Introduction [00:00:00] Jeremy: I'm here at RubyConf San Diego with Mike Perham. He's the creator of Sidekiq and Faktory. [00:00:07] Mike: Thank you, Jeremy, for having me here. It's a pleasure. Sidekiq [00:00:11] Jeremy: So for people who aren't familiar with, I guess we'll start with Sidekiq because I think that's what you're most known for. If people don't know what it is, maybe you can give like a small little explanation. [00:00:22] Mike: Ruby apps generally have two major pieces of infrastructure powering them. You've got your app server, which serves your webpages and the browser. And then you generally have something off on the side that... It processes, you know, data for a million different reasons, and that's generally called a background job framework, and that's what Sidekiq is. [00:00:41] It, Rails is usually the thing that, that handles your web stuff, and then Sidekiq is the Sidekiq to Rails, so to speak. [00:00:50] Jeremy: And so this would fit the same role as, I think in Python, there's celery. and then in the Ruby world, I guess there is, uh, Resque is another kind of job. [00:01:02] Mike: Yeah, background job frameworks are quite prolific in Ruby. the Ruby community's kind of settled on that as the, the standard pattern for application development. So yeah, we've got, a half a dozen to a dozen different, different examples throughout history, but the major ones today are, Sidekiq, Resque, DelayedJob, GoodJob, and, and, and others down the line, yeah. Why background jobs are so common in Ruby [00:01:25] Jeremy: I think working in other languages, you mentioned how in Ruby, there's this very clear, preference to use these job scheduling systems, these job queuing systems, and I'm not. I'm not sure if that's as true in, say, if somebody's working in Java, or C sharp, or whatnot. And I wonder if there's something specific about Ruby that makes people kind of gravitate towards this as the default thing they would use. [00:01:52] Mike: That's a good question. What makes Ruby... The one that so needs a background job system. I think Ruby, has historically been very single threaded. And so, every Ruby process can only do so much work. And so Ruby oftentimes does, uh, spin up a lot of different processes, and so having processes that are more focused on one thing is, is, is more standard. [00:02:24] So you'll have your application server processes, which focus on just serving HTTP responses. And then you have some other sort of focused process and that just became background job processes. but yeah, I haven't really thought of it all that much. But, uh, you know, something like Java, for instance, heavily multi threaded. [00:02:45] And so, and extremely heavyweight in terms of memory and startup time. So it's much more frequent in Java that you just start up one process and that's it. Right, you just do everything in that one process. And so you may have dozens and dozens of threads, both serving HTTP and doing work on the side too. Um, whereas in Ruby that just kind of naturally, there was a natural split there. Global Interpreter Lock [00:03:10] Jeremy: So that's actually a really good insight, because... in the keynote at RubyConf, Mats, the creator of Ruby, you know, he mentioned the, how the fact that there is this global, interpreter lock, [00:03:23] or, or global VM lock in Ruby, and so you can't, really do multiple things in parallel and make use of all the different cores. And so it makes a lot of sense why you would say like, okay, I need to spin up separate processes so that I can actually take advantage of, of my, system. [00:03:43] Mike: Right. Yeah. And the, um, the GVL. is the acronym we use in the Ruby community, or GIL. Uh, that global lock really kind of is a forcing function for much of the application architecture in Ruby. Ruby, uh, applications because it does limit how much processing a single Ruby process can do. So, uh, even though Sidekiq is heavily multi threaded, you can only have so many threads executing. [00:04:14] Because they all have to share one core because of that global lock. So unfortunately, that's, that's been, um, one of the limiter, limiting factors to Sidekiq scalability is that, that lock and boy, I would pay a lot of money to just have that lock go away, but. You know, Python is going through a very long term experiment about trying to remove that lock and I'm very curious to see how well that goes because I would love to see Ruby do the same and we'll see what happens in the future, but, it's always frustrating when I come to another RubyConf and I hear another Matt's keynote where he's asked about the GIL and he continues to say, well, the GIL is going to be around, as long as I can tell. [00:04:57] so it's a little bit frustrating, but. It's, it's just what you have to deal with. Ractors [00:05:02] Jeremy: I'm not too familiar with them, but they, they did mention during the keynote I think there Ractors or something like that. There, there, there's some way of being able to get around the GIL but there are these constraints on them. And in the context of Sidekiq and, and maybe Ruby in general, how do you feel about those options or those solutions? [00:05:22] Mike: Yeah, so, I think it was Ruby 3. 2 that introduced this concept of what they call a Ractor, which is like a thread, except it does not have the global lock. It can run independent to the global lock. The problem is, is because it doesn't use the global lock, it has pretty severe constraints on what it can do. [00:05:47] And the, and more specifically, the data it can access. So, Ruby apps and Rails apps throughout history have traditionally accessed a lot of global data, a lot of class level data, and accessed all this data in a, in a read only fashion. so there's no race conditions because no one's changing any of it, but it's still, lots of threads all accessing the same variables. [00:06:19] Well, Ractors can't do that at all. The only data Ractors can access is data that they own. And so that is completely foreign to Ruby application, traditional Ruby applications. So essentially, Ractors aren't compatible with the vast majority of existing Ruby code. So I, I, I toyed with the idea of prototyping Sidekiq and Ractors, and within about a minute or two, I just ran into these, these, uh... [00:06:51] These very severe constraints, and so that's why you don't see a lot of people using Ractors, even still, even though they've been out for a year or two now, you just don't see a lot of people using them, because they're, they're really limited, limited in what they can do. But, on the other hand, they're unlimited in how well they can scale. [00:07:12] So, we'll see, we'll see. Hopefully in the future, they'll make a lot of improvements and, uh, maybe they'll become more usable over time. Downsides of multiprocess (Memory usage) [00:07:19] Jeremy: And with the existence of a job queue or job scheduler like Sidekiq, you're able to create additional processes to get around that global lock, I suppose. What are the... downsides of doing so versus another language like we mentioned Java earlier, which is capable of having true parallelism in the same process. [00:07:47] Mike: Yeah, so you can start up multiple Ruby processes to process things truly in parallel. The issue is that you do get some duplication in terms of memory. So your Ruby app maybe take a gigabyte per process. And, you can do copy on write forking. You can fork and get some memory sharing with copy on write semantics on Unix operating systems. [00:08:21] But you may only get, let's say, 30 percent memory savings. So, there's still a significant memory overhead to forking, you know, let's say, eight processes versus having eight threads. You know, you, you, you may have, uh, eight threads can operate in a gigabyte process, but if you want to have eight processes, that may take, let's say, four gigabytes of RAM. [00:08:48] So you, you still, it's not going to cost you eight gigabytes of RAM, you know, it's not like just one times eight, but, there's still a overhead of having those separate processes. [00:08:58] Jeremy: would you say it's more of a cost restriction, like it costs you more to run these applications, or are there actual problems that you can't solve because of this restriction. [00:09:13] Mike: Help me understand, what do you mean by restriction? Do you mean just the GVL in general, or the fact that forking processes still costs memory? [00:09:22] Jeremy: I think, well, it would be both, right? So you're, you have two restrictions right now. You have the, the GVL, which means you can't have parallelism within the same process. And then your other option is to spin up a bunch of processes, which you have said is the downside there is that you're using a lot more RAM. [00:09:43] I suppose my question is that Does that actually stop you from doing anything? Like, if you throw more money at the problem, you go like, we're going to have more instances, I'll pay for the RAM, it's fine, can that basically get you out of these situations or are these limitations actually stopping you from, from doing things you could do in other languages? [00:10:04] Mike: Well, you certainly have to manage the multiple processes, right? So you've gotta, you know, if one child process crashes, you've gotta have a parent or supervisor process watching all that and monitoring and restarting the process. I don't think it restricts you. Necessarily, it just, it adds complexity to your deployment. [00:10:24] and, and it's just a question of efficiency, right? Instead of being able to deploy on a, on a one gigabyte droplet, I've got to deploy to a four gigabyte droplet, right? Because I just, I need the RAM to run the eight processes. So it, it, it's more of just a purely a function of how much money am I going to have to throw at this problem. [00:10:45] And what's it going to cost me in operational costs to operate this application in production? When to use other languages? [00:10:53] Jeremy: So during the. Keynote, uh, Matz had mentioned that Rails, is really suitable as this one person framework, like you can have a very small team or maybe even yourself and, and build this product. And so I guess from... Your perspective, once you cross a certain threshold, is like, what Ruby and what Sidekiq provides not enough, and that's why you need to start looking into other languages? [00:11:24] Or like, where's the, turning point, or the, if you [00:11:29] Mike: Right, right. The, it's all about the problem you're trying to solve, right? At the end of the day, uh, the, the question is just what are we trying to solve and how are we trying to solve it? So at a higher level, you got to think about the architecture. if the problem you're trying to solve, if the service you're trying to build, if the app you're trying to operate. [00:11:51] If that doesn't really fall into the traditional Ruby application architecture, then you, you might look at it in another language or another ecosystem. something like Go, for instance, can compile down to a single binary, which makes deployment really easy. It makes shipping up a product. on to a user's machine, much simpler than deploying a Ruby application onto a user's desktop machine, for instance, right? [00:12:22] Um, Ruby does have this, this problem of how do you package everything together and deploy it somewhere? Whereas Go, when you can just compile to a single binary, now you've just got a single thing. And it's just... Drop it on the file system and execute it. It's easy. So, um, different, different ecosystems have different application architectures, which empower different ways of solving the same problems. [00:12:48] But, you know, Rails as a, as a one man framework, or sorry, one person framework, It, it, I don't, I don't necessarily, that's a, that's sort of a catchy marketing slogan, but I just think of Rails as the most productive framework you can use. So you, as a single person, you can maximize what you ship and the, the, the value that you can create because Rails is so productive. [00:13:13] Jeremy: So it, seems like it's maybe the, the domain or the type of application you're making. Like you mentioned the command line application, because you want to be able to deliver it to your user easily. Just give them a binary, something like Go or perhaps Rust makes a lot more sense. and then I could see people saying that if you're doing something with machine learning, like the community behind Python, it's, they're just, they're all there. [00:13:41] So Room for more domains in Ruby [00:13:41] Mike: That was exactly the example I was going to use also. Yeah, if you're doing something with data or AI, Python is going to be a more, a more traditional, natural choice. that doesn't mean Ruby can't do it. That doesn't mean, you wouldn't be able to solve the problem with Ruby. And, and there's, that just also means that there's more space for someone who wants to come in and make an impact in the Ruby community. [00:14:03] Find a problem that Ruby's not really well suited to solving right now and build the tooling out there to, to try and solve it. You know, I, I saw a talk, from the fellow who makes the Glimmer gem, which is a native UI toolkit. Uh, a gem for building native UIs in Ruby, which Ruby traditionally can't do, but he's, he's done an amazing job at sort of surfacing APIs to build these, um, these native, uh, native applications, which I think is great. [00:14:32] It's awesome. It's, it's so invigorating to see Ruby in a new space like that. Um, I talked to someone else who's doing the Polars gem, which is focused on data processing. So it kind of takes, um, Python and Pandas and brings that to Ruby, which is, is awesome because if you're a Ruby developer, now you've got all these additional tools which can allow you to solve new sets of problems out there. [00:14:57] So that's, that's kind of what's exciting in the Ruby community right now is just bring it into new spaces. Faktory [00:15:03] Jeremy: In addition to Sidekiq, you have, uh, another product called Faktory, I believe. And so does that serve a, a similar purpose? Is that another job scheduling, job queueing system? [00:15:16] Mike: It is, yes. And it's, it's, it's similar in a way to Sidekiq. It looks similar. It's got similar concepts at the core of it. At the end of the day, Sidekiq is limited to Ruby. Because Sidekiq executes in a Ruby VM, it executes the jobs, and the jobs are, have to be written in Ruby because you're running in the Ruby VM. [00:15:38] Faktory was my attempt to bring, Sidekiq functionality to every other language. I wanted, I wanted Sidekiq for JavaScript. I wanted Sidekiq for Go. I wanted Sidekiq for Python because A, a lot of these other languages also could use a system, a background job system. And the problem though is that. [00:16:04] As a single man, I can't port Sidekiq to every other language. I don't know all the languages, right? So, Faktory kind of changes the architecture and, um, allows you to execute jobs in any language. it, it replaces Redis and provides a server where you just fetch jobs, and you can use it from it. [00:16:26] You can use that protocol from any language to, to build your own worker processes that execute jobs in whatever language you want. [00:16:35] Jeremy: When you say it replaces Redis, so it doesn't use Redis, um, internally, it has its own. [00:16:41] Mike: It does use Redis under the covers. Yeah, it starts Redis as a child process and, connects to it over a Unix socket. And so it's really stable. It's really fast. from the outside, the, the worker processes, they just talk to Faktory. They don't know anything about Redis at all. [00:16:59] Jeremy: I see. And for someone who, like we mentioned earlier in the Python community, for example, there is, um, Celery. For someone who is using a task scheduler like that, what's the incentive to switch or use something different? [00:17:17] Mike: Well, I, I always say if you're using something right now, I'm not going to try and convince you to switch necessarily. It's when you have pain that you want to switch and move away. Maybe you have Maybe there's capabilities in the newer system that you really need that the old system doesn't provide, but Celery is such a widely known system that I'm not necessarily going to try and convince people to move away from it, but if people are looking for a new system, one of the things that Celery does that Faktory does not do is Celery provides like data adapters for using store, lots of different storage systems, right? [00:17:55] Faktory doesn't do that. Faktory is more, has more of the Rails mantra of, you know, Omakase where we choose, I choose to use Redis and that's it. You don't, you don't have a choice for what to use because who cares, you know, at the end of the day, let Faktory deal with it. it's, it's not something that, You should even necessarily be concerned about it. [00:18:17] Just, just try Faktory out and see how it works for you. Um, so I, I try to take those operational concerns off the table and just have the user focus on, you know, usability, performance, and that sort of thing. but it is, it's, it's another background job system out there for people to try out and see if they like that. [00:18:36] And, and if they want to, um, if they know Celery and they want to use Celery, more power to Faktory them. Sidekiq (Ruby) or Faktory (Polyglot) [00:18:43] Jeremy: And Sidekiq and Faktory, they serve a very similar purpose. For someone who they have a new project, they haven't chosen a job. scheduling system, if they were using Ruby, would it ever make sense for them to use Faktory versus use Sidekiq? [00:19:05] Mike: Uh Faktory is excellent in a polyglot situation. So if you're using multiple languages, if you're creating jobs in Ruby, but you're executing them in Python, for instance, um, you know, if you've, I have people who are, Creating jobs in PHP and executing them in Python, for instance. That kind of polyglot scenario, Sidekiq can't do that at all. [00:19:31] So, Faktory is useful there. In terms of Ruby, Ruby is just another language to Faktory. So, there is a Ruby API for using Faktory, and you can create and execute Ruby jobs with Faktory. But, you'll find that in the Ruby community, Sidekiq is much widely... much more widely used and understood and known. So if you're just using Ruby, I think, I think Sidekiq is the right choice. [00:19:59] I wouldn't look at Faktory. But if you do need, find yourself needing that polyglot tool, then Faktory is there. Temporal [00:20:07] Jeremy: And this is maybe one, maybe one layer of abstraction higher, but there's a product called Temporal that has some of this job scheduling, but also this workflow component. I wonder if you've tried that out and how you think about that product? [00:20:25] Mike: I've heard of them. I don't know a lot about the product. I do have a workflow API, the Sidekiq batches, which allow you to fan out jobs and then, and then execute callbacks when all the jobs in that, in that batch are done. But I don't, provide sort of a, a high level. Graphical Workflow Editor or anything like that. [00:20:50] Those to me are more marketing tools that you use to sell the tool for six figures. And I don't think they're usable. And I don't think they're actually used day to day. I provide an API for developers to use. And developers don't like moving blocks of code around in a GUI. They want to write code. And, um, so yeah, temporal, I, like I said, I don't know much about them. [00:21:19] I also, are they a venture capital backed startup? [00:21:22] Jeremy: They are, is my understanding, [00:21:24] Mike: Yeah, that, uh, any, any sort of venture capital backed startup, um, who's building technical infrastructure. I, I would look long and hard at, I'm, I think open source is the right core to build on. Of course I sell commercial software, but. I'm bootstrapped. I'm profitable. [00:21:46] I'm going to be around forever. A VC backed startup, they tend to go bankrupt, because they either get big or they go out of business. So that would be my only comment is, is, be a little bit leery about relying on commercial venture capital based infrastructure for, for companies, uh, long term. Getting people to pay for Sidekiq [00:22:05] Jeremy: So I think that's a really interesting part about your business is that I think a lot of open source maintainers have a really big challenge figuring out how to make it as a living. The, there are so many projects that they all have a very permissive license and you can use them freely one example I can think of is, I, I talked with, uh, David Kramer, who's the CTO at Sentry, and he, I don't think they use it anymore, but they, they were using Nginx, right? [00:22:39] And he's like, well, Nginx, they have a paid product, like Nginx. Plus that or something. I don't know what the name is, but he was like, but I'm not going to pay for it. Right. I'm just going to use the free one. Why would I, you know, pay for the, um, the paid thing? So I, I, I'm kind of curious from your perspective when you were coming up with Sidekiq both as an open source product, but also as a commercial one, how did you make that determination of like to make a product where it's going to be useful in its open source form? [00:23:15] I can still convince people to pay money for it. [00:23:19] Mike: Yeah, the, I was terrified, to be blunt, when I first started out. when I started the Sidekiq project, I knew it was going to take a lot of time. I knew if it was successful, I was going to be doing it for the next decade. Right? So I started in 2012, and here I am in 2023, over a decade, and I'm still doing it. [00:23:38] So my expectation was met in that regard. And I knew I was not going to be able to last that long. If I was making zero dollars, right? You just, you burn out. Nobody can last that long. Well, I guess there are a few exceptions to that rule, but yeah, money, I tend to think makes things a little more sustainable for sure. [00:23:58] Especially if you can turn it into a full time job solving and supporting a project that you, you love and, and is, is, you know, your, your, your baby, your child, so to speak, your software, uh, uh, creation that you've given to the world. but I was terrified. but one thing I did was at the time I was blogging a lot. [00:24:22] And so I was telling people about Sidekiq. I was telling people what was to come. I was talking about ideas and. The one thing that I blogged about was financial experiments. I said bluntly to the, to, to the Ruby community, I'm going to be experimenting with financial stability and sustainability with this project. [00:24:42] So not only did I create this open source project, but I was also publicly saying I I need to figure out how to make this work for the next decade. And so eventually that led to Sidekiq Pro. And I had to figure out how to build a closed source Ruby gem, which, uh, There's not a lot of, so I was kind of in the wild there. [00:25:11] But, you know, thankfully all the pieces came together and it was actually possible. I couldn't have done it if it wasn't possible. Like, we would not be talking if I couldn't make a private gem. So, um, but it happened to work out. Uh, and it allowed me to, to gate features behind a paywall effectively. And, and yeah, you're right. [00:25:33] It can be tough to make people pay for software. but I'm a developer who's selling to other developers, not, not just developers, open source developers, and they know that they have this financial problem, right? They know that there's this sustainability problem. And I was blunt in saying, this is my solution to my sustainability. [00:25:56] So, I charge what I think is a very fair price. It's only a thousand dollars a year to a hobbyist. That may seem like a lot of money to a business. It's a drop in the bucket. So it was easy for developers to say, Hey, listen, we want to buy this tool for a thousand bucks. It'll ensure our infrastructure is maintained for the next decade. [00:26:18] And it's, and it's. And it's relatively cheap. It's way less than, uh, you know, a salary or even a laptop. So, so that's, that's what I did. And, um, it's, it worked out great. People, people really understood. Even today, I talk to people and they say, we, we signed up for Sidekiq Pro to support you. So it's, it's, it's really, um, invigorating to hear people, uh, thank me and, and they're, they're actively happy that they're paying me and our customers. [00:26:49] Jeremy: it's sort of, uh, maybe a not super common story, right, in terms of what you went through. Because when I think of open core businesses, I think of companies like, uh, GitLab, which are venture funded, uh, very different scenario there. I wonder, like, in your case, so you started in 2012, and there were probably no venture backed competitors, right? [00:27:19] People saying that we're going to make this job scheduling system and some VC is going to give me five million dollars and build a team to work on this. It was probably at the time, maybe it was Rescue, which was... [00:27:35] Mike: There was a venture backed system called IronMQ, [00:27:40] Jeremy: Hmm. [00:27:41] Mike: And I'm not sure if they're still around or not, but they... They took, uh, one or more funding rounds. I'm not sure exactly, but they were VC backed. They were doing, background jobs, scheduled jobs, uh, you know, running container, running container jobs. They, they eventually, I think, wound up sort of settling on Docker containers. [00:28:06] They'll basically spin up a Docker container. And that container can do whatever it wants. It can execute for a second and then shut down, or it can run for, for however long, but they would, um, yeah, I, yeah, I'll, I'll stop there because I don't know the actual details of exactly their system, but I'm not sure if they're still around, but that's the only one that I remember offhand that was around, you know, years ago. [00:28:32] Yeah, it's, it's mostly, you know, low level open source infrastructure. And so, anytime you have funded startups, they're generally using that open source infrastructure to build their own SaaS. And so SaaS's are the vast majority of where you see sort of, uh, commercial software. [00:28:51] Jeremy: so I guess in that way it, it, it gave you this, this window or this area where you could come in and there wasn't, other than that iron, product, there wasn't this big money that you were fighting against. It was sort of, it was you telling people openly, I'm, I'm working on this thing. [00:29:11] I need to make money so that I can sustain it. And, if you, yeah. like the work I do, then, you know, basically support me. Right. And, and so I think that, I'm wondering how we can reproduce that more often because when you see new products, a lot of times it is VC backed, right? [00:29:35] Because people say, I need to work on this. I need to be paid. and I can't ask a team to do this. For nothing, right? So [00:29:44] Mike: Yeah. It's. It's a wicked problem. Uh, it's a really, really hard problem to solve if you take vc you there, that that really kind of means that you need to be making tens if not hundreds of millions of dollars in sales. If you are building a small or relatively small. You know, put small in quotes there because I don't really know what that means, but if you have a small open source project, you can't charge huge amounts for it, right? [00:30:18] I mean, Sidekiq is a, I would call a medium sized open source project, and I'm charging a thousand bucks for it. So if you're building, you know, I don't know, I don't even want to necessarily give example, but if you're building some open source project, and It's one of 300 libraries that people's applications will depend on. [00:30:40] You can't necessarily charge a thousand dollars for that library. depending on the size and the capabilities, maybe you can, maybe you can't. But there's going to be a long tail of open source projects that just, they can't, they can't charge much, if anything, for them. So, unfortunately, we have, you know, these You kind of have two pathways. [00:31:07] Venture capital, where you've got to sell a ton, or free. And I've kind of walked that fine line where I'm a small business, I can charge a small amount because I'm bootstrapped. And, and I don't need huge amounts of money, and I, and I have a project that is of the right size to where I can charge a decent amount of money. [00:31:32] That means that I can survive with 500 or a thousand customers. I don't need to have a hundred million dollars worth of customers. Because I, you know, when I started the business, one of the constraints I said is I don't want to hire anybody. I'm just going to be solo. And part of the, part of my ability to keep a low price and, and keep running sustainably, even with just You know, only a few hundred customers is because I'm solo. [00:32:03] I don't have the overhead of investors. I don't have the overhead of other employees. I don't have an office space. You know, my overhead is very small. So that is, um, you know, I just kind of have a unique business in that way, I guess you might say. Keeping the business solo [00:32:21] Jeremy: I think that's that's interesting about your business as well But the fact that you've kept it you've kept it solo which I would imagine in most businesses, they need support people. they need, developers outside of maybe just one. Um, there's all sorts of other, I don't think overhead is the right word, but you just need more people, right? [00:32:45] And, and what do you think it is about Sidekiq that's made it possible for it to just be a one person operation? [00:32:52] Mike: There's so much administrative overhead in a business. I explicitly create business policies so that I can run solo. you know, my support policy is officially you get one email ticket or issue per quarter. And, and anything more than that, I can bounce back and say, well, you're, you're requiring too much support. [00:33:23] In reality, I don't enforce that at all. And people email me all the time, but, but things like. Things like dealing with accounting and bookkeeping and taxes and legal stuff, licensing, all that is, yeah, a little bit of overhead, but I've kept it as minimal as I can. And part of that is I don't want to hire another employee because then that increases the administrative overhead that I have. [00:33:53] And Sidekiq is so tied to me and my knowledge that if I hire somebody, they're probably not going to know Ruby and threading and all the intricate technical detail necessary to build and maintain and support the system. And so really you'll kind of regress a little bit. We won't be able to give as good support because I'm busy helping that other employee. Being selective about customers [00:34:23] Mike: So, yeah, it's, it's a tightrope act where you've got to really figure out how can I scale myself as far as possible without overwhelming myself. The, the overwhelming thing that I have that I've never been able to solve. It's just dealing with billing inquiries, customers, companies, emailing me saying, how do we buy this thing? [00:34:46] Can I get an invoice? Every company out there, it seems wants an invoice. And the problem with invoicing is it takes a lot more. manual labor and administrative overhead to issue that invoice to collect payment on the invoice. So that's one of the reasons why I have a very strict policy about credit card only for, for the vast majority of my customers. [00:35:11] And I demand that companies pay a lot more. You have to have a pretty big enterprise license if you want an invoice. And if the company, if the company comes back and complains and says, well, you know, that's ridiculous. We don't, we don't want to pay that much. We don't need it that much. Uh, you know, I, I say, okay, well then you have two, two things, two, uh, two things. [00:35:36] You can either pay with a credit card or you can not use Sidekiq. Like, that's, that's it. I'm, I don't need your money. I don't want the administrative overhead of dealing with your accounting department. I just want to support my, my customers and build my software. And, and so, yeah, I don't want to turn into a billing clerk. [00:35:55] So sometimes, sometimes the, the, the best thing in business that you can do is just say no. [00:36:01] Jeremy: That's very interesting because I think being a solo... Person is what probably makes that possible, right? Because if you had the additional staff, then you might say like, Well, I need to pay my staff, so we should be getting, you know, as much business as [00:36:19] Mike: Yeah. Chasing every customer you can, right. But yeah. [00:36:22] Every customer is different. I mean, I have some customers that just, they never contact me. They pay their bill really fast or right on time. And they're paying me, you know, five figures, 20, a year. And they just, it's a, God bless them because those are, are the. [00:36:40] Best customers to have and the worst customers are the ones who are paying 99 bucks a month and everything that they don't understand or whatever is a complaint. So sometimes, sometimes you, you want to, vet your customers from that perspective and say, which one of these customers are going to be good? [00:36:58] Which ones are going to be problematic? [00:37:01] Jeremy: And you're only only person... And I'm not sure how many customers you have, but [00:37:08] Mike: I have 2000 [00:37:09] Jeremy: 2000 customers. [00:37:10] Okay. [00:37:11] Mike: Yeah. [00:37:11] Jeremy: And has that been relatively stable or has there been growth [00:37:16] Mike: It's been relatively stable the last couple of years. Ruby has, has sort of plateaued. Um, it's, you don't see a lot of growth. I'm getting probably, um, 15, 20 percent growth maybe. Uh, so I'm not growing like a weed, like, you know, venture capital would want to see, but steady incremental growth is, is, uh, wonderful, especially since I do very little. [00:37:42] Sales and marketing. you know, I come to RubyConf I, I I tweet out, you know, or I, I toot out funny Mastodon Toots occasionally and, and, um, and, and put out new releases of the software. And, and that's, that's essentially my, my marketing. My marketing is just staying in front of developers and, and, and being a presence in the Ruby community. [00:38:06] But yeah, it, it's, uh. I, I, I see not a, not a huge amount of churn, but I see enough sales to, to, to stay up and keep my head above water and to keep growing, um, slowly but surely. Support needs haven't grown [00:38:20] Jeremy: And as you've had that steady growth, has the support burden not grown with it? [00:38:27] Mike: Not as much because once customers are on Sidekiq and they've got it working, then by and large, you don't hear from them all that much. There's always GitHub issues, you know, customers open GitHub issues. I love that. but yeah, by and large, the community finds bugs. and opens up issues. And so things remain relatively stable. [00:38:51] I don't get a lot of the complete newbie who has no idea what they're doing and wants me to, to tell them how to use Sidekiq that I just don't see much of that at all. Um, I have seen it before, but in that case, generally, I, I, I politely tell that person that, listen, I'm not here to educate you on the product. [00:39:14] It's there's documentation in the wiki. Uh, and there's tons of, of more Ruby, generic Ruby, uh, educational material out there. That's just not, not what I do. So, so yeah, by and large, the support burden is, is not too bad because once people are, are up and running, it's stable and, and they don't, they don't need to contact me. [00:39:36] Jeremy: I wonder too, if that's perhaps a function of the price, because if you're a. new developer or someone who's not too familiar with how to do job processing or what they want to do when you, there is the open source product, of course. but then the next step up, I believe is about a hundred dollars a month. [00:39:58] And if you're somebody who is kind of just getting started and learning how things work, you're probably not going to pay that, is my guess. And so you'll never hear from them. [00:40:11] Mike: Right, yeah, that's a good point too, is the open source version, which is what people inevitably are going to use and integrate into their app at first. Because it's open source, you're not going to email me directly, um, and when people do email me directly, Sidekiq support questions, I do, I reply literally, I'm sorry I don't respond to private email, unless you're a customer. [00:40:35] Please open a GitHub issue and, um, that I try to educate both my open source users and my commercial customers to try and stay in GitHub issues because private email is a silo, right? Private email doesn't help anybody else but them. If I can get people to go into GitHub issues, then that's a public record. [00:40:58] that people can search. Because if one person has that problem, there's probably a dozen other people that have that same problem. And then that other, those other 11 people can search and find the solution to their problem at four in the morning when I'm asleep. Right? So that's, that's what I'm trying to do is, is keep, uh, keep everything out in the open so that people can self service as much as possible. Sidekiq open source [00:41:24] Jeremy: And on the open source side, are you still primarily the main contributor? Or do you have other people that are [00:41:35] Mike: I mean, I'd say I do 90 percent of the work, which is why I don't feel guilty about keeping 100 percent of the money. A lot of open source projects, when they look for financial sustainability, they also look for how can we split this money amongst the team. And that's, that's a completely different topic that I've. [00:41:55] is another reason why I've stayed solo is if I hire an employee and I pay them 200, 000 a year as a developer, I'm meanwhile keeping all the rest of the profits of the company. And so that almost seems a little bit unfair. because we're both still working 40 hours a week, right? Why am I the one making the vast majority of the, of the profit and the money? [00:42:19] Um, so, uh, I've always, uh, that's another reason why I've stayed solo, but, but yeah, having a team of people working on something, I do get, regular commits, regular pull requests from people, fixing a bug that they found or just making a tweak that. that they saw, that they thought they could improve. [00:42:42] A little more rarely I get a significant improvement or feature, as a pull request. but Sidekiq is so stable these days that it really doesn't need a team of people maintaining it. The volume of changes necessary, I can easily keep up with that. So, I'm still doing 90 95 percent of the work. Are there other Sidekiq-like opportunities out there? [00:43:07] Jeremy: Yeah, so I think Sidekiq has sort of a unique positioning where it's the code base itself is small enough where you can maintain it yourself and you have some help, but primarily you're the main maintainer. And then you have enough customers who are willing to, to pay for the benefit it gives them on top of what the open source product provides. [00:43:36] cause it's, it's, you were talking about how. Every project people work on, they have, they could have hundreds of dependencies, right? And to ask somebody to, to pay for each of them is, is probably not ever going to happen. And so it's interesting to think about how you have things like, say, you know, OpenSSL, you know, it's a library that a whole bunch of people rely on, but nobody is going to pay a monthly fee to use it. [00:44:06] You have things like, uh, recently there was HashiCorp with Terraform, right? They, they decided to change their license because they, they wanted to get, you know, some of that value back, some of the money back, and the community basically revolted. Right? And did a fork. And so I'm kind of curious, like, yeah, where people can find these sweet spots like, like Sidekiq, where they can find this space where it's just small enough where you can work on it on your own and still get people to pay for it. [00:44:43] It's, I'm trying to picture, like, where are the spaces? Open source as a public utility [00:44:48] Mike: We need to look at other forms of financing beyond pure capitalism. If this is truly public infrastructure that needs to be maintained for the long term, then why are we, why is it that we depend on capitalism to do that? Our roads, our water, our sewer, those are not Capitalist, right? Those are utilities, that's public infrastructure that we maintain, that the government helps us maintain. [00:45:27] And in a sense, tech infrastructure is similar or could be thought of in a similar fashion. So things like Open Collective, things like, uh, there's a, there's a organization in Europe called NLNet, I think, out of the Netherlands. And they do a lot of grants to various open source projects to help them improve the state of digital infrastructure. [00:45:57] They support, for instance, Mastodon as a open source project that doesn't have any sort of corporate backing. They see that as necessary social media infrastructure, uh, for the long term. And, and I, and I think that's wonderful. I like to see those new directions being explored where you don't have to turn everything into a product, right? [00:46:27] And, and try and market and sale, um, and, and run ads and, and do all this stuff. If you can just make the case that, hey, this is, this is useful public infrastructure that so many different, um, Technical, uh, you know, applications and businesses could rely on, much like FedEx and DHL use our roads to the benefit of their own, their own corporate profits. [00:46:53] Um, why, why, why shouldn't we think of tech infrastructure sort of in a similar way? So, yeah, I would like to see us explore more. in that direction. I understand that in America that may not happen for quite a while because we are very, capitalist focused, but it's encouraging to see, um, places like Europe, uh, a little more open to, to trialing things like, cooperatives and, and grants and large long term grants to, to projects to see if they can, uh, provide sustainability in, in, you know, in a new way. [00:47:29] Jeremy: Yeah, that's a good point because I think right now, a lot of the open source infrastructure that we all rely on, either it's being paid for by large companies and at the whim of those large companies, if Google decides we don't want to pay for you to work on this project anymore, where does the money come from? [00:47:53] Right? And on the other hand, there's the thousands, tens of thousands of people who are doing it. just for free out of the, you know, the goodness of their, their heart. And that's where a lot of the burnout comes from. Right. So I think what you're saying is that perhaps a lot of these pieces that we all rely on, that our, our governments, you know, here in the United States, but also around the world should perhaps recognize as this is, like you said, this is infrastructure, and we should be. [00:48:29] Paying these people to keep the equivalent of the roads and, and, uh, all that working. [00:48:37] Mike: Yeah, I mean, I'm not, I'm not claiming that it's a perfect analogy. There's, there's, there's lots of questions that are unanswered in that, right? How do you, how do you ensure that a project is well maintained? What does that even look like? What does that mean? you know, you can look at a road and say, is it full of potholes or is it smooth as glass, right? [00:48:59] It's just perfectly obvious, but to a, to a digital project, it's, it's not as clear. So, yeah, but, but, but exploring those new ways because turning everybody into a businessman so that they can, they can keep their project going, it, it, it itself is not sustainable, right? so yeah, and that's why everything turns into a SaaS because a SaaS is easy to control. [00:49:24] It's easy to gatekeep behind a paywall and it's easy to charge for, whereas a library on GitHub. Yeah. You know, what do you do there? You know, obviously GitHub has sponsors, the sponsors feature. You've got Patreon, you've got Open Collective, you've got Tidelift. There's, there's other, you know, experiments that have been run, but nothing has risen to the top yet. [00:49:47] and it's still, it's still a bit of a grind. but yeah, we'll see, we'll see what happens, but hopefully people will keep experimenting and, and maybe, maybe governments will start. Thinking in the direction of, you know, what does it mean to have a budget for digital infrastructure maintenance? [00:50:04] Jeremy: Yeah, it's interesting because we, we started thinking about like, okay, where can we find spaces for other Sidekiqs? But it sounds like maybe, maybe that's just not realistic, right? Like maybe we need more of a... Yeah, a rethinking of, I guess the, the structure of how people get funded. Yeah. [00:50:23] Mike: Yeah, sometimes the best way to solve a problem is to think at a higher level. You know, we, the, the sustainability problem in American Silicon Valley based open source developers is naturally going to tend toward venture capital and, and capitalism. And I, you know, I think, I think that's, uh, extremely problematic on a, on a lot of different, in a lot of different ways. [00:50:47] And, and so sometimes you need to step back and say, well, maybe we're, maybe we just don't have the right tool set to solve this problem. But, you know, I, I. More than that, I'm not going to speculate on because it is a wicked problem to solve. [00:51:04] Jeremy: Is there anything else you wanted to, to mention or thought we should have talked about? [00:51:08] Mike: No, I, I, I loved the talk, of sustainability and, and open source. And I, it's, it's a, it's a topic really dear to my heart, obviously. So I, I am happy to talk about it at length with anybody, anytime. So thank you for having me. [00:51:25] Jeremy: All right. Thank you very much, Mike.

[00:00:00] Jeremy: I'm here at RubyConf, San Diego, with Sara Jackson, thank you for joining me today. [00:00:05] Sara: Thank you for having me. Happy to be here. [00:00:07] Jeremy: Sara right now you're working at, ThoughtBot, as a, as a Ruby developer, is that right? [00:00:12] Sara: Yes, that is correct. Teaching in Japan [00:00:14] Jeremy: But I think before we kind of talk about that, I mean, we're at a Ruby conference, but something that I, I saw, on your LinkedIn that I thought was really interesting was that you were teaching, I think, programming in. Kanazawa, for a couple years. [00:00:26] Sara: Yeah, that's right. So for those that don't know, Kanazawa is a city on the west coast of Japan. If you draw kind of a horizontal line across Japan from Tokyo, it's, it's pretty much right there on the west coast. I was an associate professor in the Global Information and Management major, which is basically computer science or software development. (laughs) Yep. [00:00:55] Jeremy: Couldn't tell from the title. [00:00:56] Sara: You couldn't. No.. so there I was teaching classes for a bunch of different languages and concepts from Java to Python to Unix and Bash scripting, just kind of all over. [00:01:16] Jeremy: And did you plan the curriculum yourself, or did they have anything for you? [00:01:21] Sara: It depended on the class that I was teaching. So some of them, I was the head teacher. In that case, I would be planning the class myself, the... lectures the assignments and grading them, et cetera. if I was assisting on a class, then usually it would, I would be doing grading and then helping in the class. Most of the classes were, uh, started with a lecture and then. Followed up with a lab immediately after, in person. [00:01:54] Jeremy: And I think you went to, is it University of Rochester? [00:01:58] Sara: Uh, close. Uh, Rochester Institute of Technology. So, same city. Yeah. [00:02:03] Jeremy: And so, you were studying computer science there, is that right? [00:02:07] Sara: I, I studied computer science there, but I got a minor in Japanese language. and that's how, that's kind of my origin story of then teaching in Kanazawa. Because Rochester is actually the sister city with Kanazawa. And RIT has a study abroad program for Japanese learning students to go study at KIT, Kanazawa Institute of Technology, in Kanazawa, do a six week kind of immersive program. And KIT just so happens to be under the same board as the school that I went to teach at. [00:02:46] Jeremy: it's great that you can make that connection and get that opportunity, yeah. [00:02:49] Sara: Absolutely. Networking! [00:02:52] Jeremy: And so, like, as a student in Rochester, you got to see how, I suppose, computer science education was there. How did that compare when you went over to Kanazawa? [00:03:02] Sara: I had a lot of freedom with my curriculum, so I was able to actually lean on some of the things that I learned, some of the, the way that the courses were structured that I took, I remember as a freshman in 2006, one of the first courses that we took, involved, learning Unix, learning the command line, things like that. I was able to look up some of the assignments and some of the information from that course that I took to inform then my curriculum for my course, [00:03:36] Jeremy: That's awesome. Yeah. and I guess you probably also remember how you felt as a student, so you know like what worked and maybe what didn't. [00:03:43] Sara: Absolutely. And I was able to lean on that experience as well as knowing. What's important and what, as a student, I didn't think was important. Naming, formatting, and style [00:03:56] Jeremy: So what were some examples of things that were important and some that weren't? [00:04:01] Sara: Mm hmm. For Java in particular, you don't need any white space between any of your characters, but formatting and following the general Guidelines of style makes your code so much easier to read. It's one of those things that you kind of have to drill into your head through muscle memory. And I also tried to pass that on to my students, in their assignments that it's. It's not just to make it look pretty. It's not just because I'm a mean teacher. It is truly valuable for future developers that will end up reading your code. [00:04:39] Jeremy: Yeah, I remember when I went through school. The intro professor, they would actually, they would print out our code and they would mark it up with red pen, basically like a writing assignment and it would be like a bad variable name and like, white space shouldn't be here, stuff like that. And, it seems kind of funny now, but, it actually makes it makes a lot of sense. [00:04:59] Sara: I did that. [00:04:59] Jeremy: Oh, nice. [00:05:00] Sara: I did that for my students. They were not happy about it. (laughs) [00:05:04] Jeremy: Yeah, at that time they're like, why are you like being so picky, right? [00:05:08] Sara: Exactly. But I, I think back to my student, my experience as a student. in some of the classes I've taken, not even necessarily computer related, the teachers that were the sticklers, those lessons stuck the most for me. I hated it at the time. I learned a lot. [00:05:26] Jeremy: Yeah, yeah. so I guess that's an example of things that, that, that matter. The, the aesthetics or the visual part for understanding. What are some things that they were teaching that you thought like, Oh, maybe this isn't so important. [00:05:40] Sara: Hmm. Pause for effect. (laughs) So I think that there wasn't necessarily Any particular class or topic that I didn't feel was as valuable, but there was some things that I thought were valuable that weren't emphasized very well. One of the things that I feel very strongly about, and I'm sure those of you out there can agree. in RubyWorld, that naming is important. The naming of your variables is valuable. It's useful to have something that's understood. and there were some other teachers that I worked with that didn't care so much in their assignments. And maybe the labs that they assigned had less than useful names for things. And that was kind of a disappointment for me. [00:06:34] Jeremy: Yeah, because I think it's maybe hard to teach, a student because a lot of times you are writing these short term assignments and you have it pass the test or do the thing and then you never look at it again. [00:06:49] Sara: Exactly. [00:06:50] Jeremy: So you don't, you don't feel that pain. Yeah, [00:06:53] Sara: Mm hmm. But it's like when you're learning a new spoken language, getting the foundations correct is super valuable. [00:07:05] Jeremy: Absolutely. Yeah. And so I guess when you were teaching in Kanazawa, was there anything you did in particular to emphasize, you know, these names really matter because otherwise you or other people are not going to understand what you were trying to do here? [00:07:22] Sara: Mm hmm. When I would walk around class during labs, kind of peek over the shoulders of my students, look at what they're doing, it's... Easy to maybe point out at something and be like, well, what is this? I can't tell what this is doing. Can you tell me what this does? Well, maybe that's a better name because somebody else who was looking at this, they won't know, I don't know, you know, it's in your head, but you will not always be working solo. my school, a big portion of the students went on to get technical jobs from after right after graduating. it was when you graduated from the school that I was teaching at, KTC, it was the equivalent of an associate's degree. Maybe 50 percent went off to a tech job. Maybe 50 percent went on to a four year university. And, and so as students, it hadn't. Connected with them always yet that oh, this isn't just about the assignment. This is also about learning how to interact with my co workers in the future. Differences between students [00:08:38] Jeremy: Yeah, I mean, I think It's hard, but, group projects are kind of always, uh, that's kind of where you get to work with other people and, read other people's code, but there's always that potential imbalance of where one person is like, uh, I know how to do this. I'll just do it. Right? So I'm not really sure how to solve that problem. Yeah. [00:09:00] Sara: Mm hmm. That's something that I think probably happens to some degree everywhere, but man, Japan really has groups, group work down. They, that's a super generalization. For my students though, when you would put them in a group, they were, they were usually really organized about who was going to do what and, kept on each other about doing things maybe there were some students that were a little bit more slackers, but it was certainly not the kind of polarized dichotomy you would usually see in an American classroom. [00:09:39] Jeremy: Yeah. I've been on both sides. I've been the person who did the work and the slacker. [00:09:44] Sara: Same. [00:09:46] Jeremy: And, uh, I feel bad about it now, but, uh, [00:09:50] Sara: We did what we had to do. [00:09:52] Jeremy: We all got the degree, so we're good. that is interesting, though. I mean, was there anything else, like, culturally different, you felt, from, you know, the Japanese university? [00:10:04] Sara: Yes. Absolutely. A lot of things. In American university, it's kind of the first time in a young person's life, usually, where they have the freedom to choose what they learn, choose where they live, what they're interested in. And so there's usually a lot of investment in your study and being there, being present, paying attention to the lecture. This is not to say that Japanese college students were the opposite. But the cultural feeling is college is your last time to have fun before you enter the real world of jobs and working too many hours. And so the emphasis on paying Super attention or, being perfect in your assignments. There was, there was a scale. There were some students that were 100 percent there. And then there were some students that were like, I'm here to get a degree and maybe I'm going to sleep in class a little bit. (laughs) That is another major difference, cultural aspect. In America, if you fall asleep in a meeting, you fall asleep in class, super rude. Don't do it. In Japan, if you take a nap at work, you take a nap in class, not rude. It's actually viewed as a sign of you are working really hard. You're usually working maybe late into the night. You're not getting enough sleep. So the fact that you need to take maybe a nap here or two here or there throughout the day means that you have put dedication in. [00:11:50] Jeremy: Even if the reason you're asleep is because you were playing games late at night. [00:11:54] Sara: Yep. [00:11:55] Jeremy: But they don't know that. [00:11:56] Sara: Yeah. But it's usually the case for my students. [00:11:59] Jeremy: Okay. I'm glad they were having fun at least [00:12:02] Sara: Me too. Why she moved back [00:12:04] Jeremy: That sounds like a really interesting experience. You did it for about two years? Three years. [00:12:12] Sara: So I had a three year contract with an option to extend up to five, although I did have a There were other teachers in my same situation who were actually there for like 10 years, so it was flexible. [00:12:27] Jeremy: Yeah. So I guess when you made the decision to, to leave, what was sort of your, your thinking there? [00:12:35] Sara: My fiance was in America [00:12:37] Jeremy: Good. [00:12:37] Sara: he didn't want to move to Japan [00:12:39] Jeremy: Good, reason. [00:12:39] Sara: Yeah, he was waiting three years patiently for me. [00:12:44] Jeremy: Okay. Okay. my heart goes out there . He waited patiently. [00:12:49] Sara: We saw each other. We, we were very lucky enough to see each other every three or four months in person. Either I would visit America or he would come visit me in Kanazawa. [00:12:59] Jeremy: Yeah, yeah. You, you couldn't convince him to, to fall in love with the country. [00:13:03] Sara: I'm getting there [00:13:04] Jeremy: Oh, you're getting Oh, [00:13:05] Sara: it's, We're making, we're making way. [00:13:07] Jeremy: Good, that's good. So are you taking like, like yearly trips or something, or? [00:13:11] Sara: That was, that was always my intention when I moved back so I moved back in the Spring of 2018 to America and I did visit. In 2019, the following year, so I could attend the graduation ceremony for the last group of students that I taught. [00:13:26] Jeremy: That's so sweet. [00:13:27] Sara: And then I had plans to go in 2020. We know what happened in 2020 [00:13:32] Jeremy: Yeah. [00:13:33] Sara: The country did not open to tourism again until the fall of 2022. But I did just make a trip last month. [00:13:40] Jeremy: Nice [00:13:40] Sara: To see some really good friends for the first time in four years. [00:13:43] Jeremy: Amazing, yeah. Where did you go? [00:13:46] Sara: I did a few days in Tokyo. I did a few days in Niigata cause I was with a friend who studied abroad there. And then a few days in Kanazawa. [00:13:56] Jeremy: That's really cool, yeah. yeah, I had a friend who lived there, but they were teaching English, yeah. And, I always have a really good time when I'm out there, yeah. [00:14:08] Sara: Absolutely. If anyone out there visiting wants to go to Japan, this is your push. Go do it. Reach out to me on LinkedIn. I will help you plan. [00:14:17] Jeremy: Nice, nice. Um, yeah, I, I, I would say the same. Like, definitely, if you're thinking about it, go. And, uh, sounds like Sara will hook you up. [00:14:28] Sara: Yep, I'm your travel guide. Technical terms in Japanese [00:14:31] Jeremy: So you, you studied, uh, you, you said you had a minor in Japanese? Yeah. So, so when you were teaching there, were you teaching classes in English or was it in Japanese? [00:14:42] Sara: It was a mix. Uh, when I was hired, the job description was no Japanese needed. It was a very, like, Global, international style college, so there was a huge emphasis on learning English. They wanted us to teach only in English. My thought was, it's hard enough learning computer science in your native language, let alone a foreign language, so my lectures were in English, but I would assist the labs in japanese [00:15:14] Jeremy: Oh, nice. Okay. And then, so you were basically fluent then at the time. Middle. Okay. Yeah. Yeah. Hey, well, I think if you're able to, to help people, you know, in labs and stuff, and it's a technical topic, right? So that's gotta be kind of a, an interesting challenge [00:15:34] Sara: I did learn a lot of new computer vocabulary. Yes. [00:15:39] Jeremy: So the words are, like, a lot of them are not the same? Or, you know, for, for specifically related to programming, I guess. [00:15:46] Sara: Hmm. Yeah, there are Japanese specific words. There's a lot of loan words that we use. We. Excuse me. There's a lot of loan words that Japanese uses for computer terms, but there's plenty that are just in Japanese. For example, uh, an array is hairetsu. [00:16:08] Jeremy: Okay. [00:16:08] Sara: And like a screen or the display that your monitor is a gamen, but a keyboard would be keyboard... Kībōdo, probably. [00:16:20] Jeremy: Yeah. So just, uh, so that, they use that as a loan word, I guess. But I'm not sure why not the other two. [00:16:27] Sara: Yeah, it's a mystery. [00:16:29] Jeremy: So it's just, it's just a total mix. Yeah. I'm just picturing you thinking like, okay, is it the English word or is it the Japanese word? You know, like each time you're thinking of a technical term. Yeah. [00:16:39] Sara: Mm hmm. I mostly, I, I I went to the internet. I searched for Japanese computer term dictionary website, and kind of just studied the terms. I also paid a lot of attention to the Japanese professors when they were teaching, what words they were using. Tried to integrate. Also, I was able to lean on my study abroad, because it was a technical Japanese, like there were classes that we took that was on technical Japanese. Computer usage, and also eco technology, like green technology. So I had learned a bunch of them previously. [00:17:16] Jeremy: Mm. So was that for like a summer or a year or something [00:17:20] Sara: It was six weeks [00:17:21] Jeremy: Six weeks. [00:17:21] Sara: During the summer, [00:17:22] Jeremy: Got it. So that's okay. So like, yeah, that must have been an experience like going to, I'm assuming that's the first time you had been [00:17:30] Sara: It was actually the second time [00:17:31] Jeremy: The second [00:17:32] Sara: Yeah. That was in 2010 that I studied abroad. [00:17:35] Jeremy: And then the classes, they were in Japanese or? Yeah. Yeah. That's, uh, that's, that's full immersion right there. [00:17:42] Sara: It was, it was very funny in the, in the very first lesson of kind of just the general language course, there was a student that was asking, I, how do I say this? I don't know this. And she was like, Nihongo de. [00:17:55] Jeremy: Oh (laughs) ! [00:17:56] Sara: You must, must ask your question only in [00:17:59] Jeremy: Yeah, Programming resources in Japanesez [00:17:59] Jeremy: yeah. yeah. That's awesome. So, so it's like, I guess the, the professors, they spoke English, but they were really, really pushing you, like, speak Japanese. Yeah, that's awesome. and maybe this is my bias because I'm an English native, but when you look up. Resources, like you look up blog posts and Stack Overflow and all this stuff. It's all in English, right? So I'm wondering for your, your students, when, when they would search, like, I got this error, you know, what do I do about it? Are they looking at the English pages or are they, you know, you know what I mean? [00:18:31] Sara: There are Japanese resources that they would use. They love Guguru (Google) sensei. [00:18:36] Jeremy: Ah okay. Okay. [00:18:38] Sara: Um, but yeah, there are plenty of Japanese language stack overflow equivalents. I'm not sure if they have stack overflow specifically in Japanese. But there are sites like that, that they, that they used. Some of the more invested students would also use English resources, but that was a minority. [00:19:00] Jeremy: Interesting. So there's a, there's a big enough community, I suppose, of people posting and answering questions and stuff where it's, you don't feel like, there aren't people doing the same thing as you out there. [00:19:14] Sara: Absolutely. Yeah. There's, a large world of software development in Japan, that we don't get to hear. There are questions and answers over here because of that language barrier. [00:19:26] Jeremy: Yeah. I would be, like, kind of curious to, to see, the, the languages and the types of problems they have, if they were similar or if it's, like, I don't know, just different. [00:19:38] Sara: Yeah, now I'm interested in that too, and I bet you there is a lot of research that we could do on Ruby, since Ruby is Japanese. [00:19:51] Jeremy: Right. cause something I've, I've often heard is that, when somebody says they're working with Ruby, Here in, um, the United States, a lot of times people assume it's like, Oh, you're doing a Rails app, [00:20:02] Sara: Mm hmm. [00:20:03] Jeremy: Almost, almost everybody who's using Ruby, not everyone, but you know, the majority I think are using it because of Rails. And I've heard that in Japan, there's actually a lot more usage that's, that's not tied to Rails. [00:20:16] Sara: I've also heard that, and I get the sense of that from RubyKaigi as well. Which I have never been lucky enough to attend. But, yeah, the talks that come out of RubyKaigi, very technical, low to the metal of Ruby, because there's that community that's using it for things other than Rails, other than web apps. [00:20:36] Jeremy: Yeah, I think, one of the ones, I don't know if it was a talk or not, but, somebody was saying that there is Ruby in space. [00:20:42] Sara: That's awesome. Ruby's everywhere. LAN parties in college [00:20:44] Jeremy: So yeah, I guess like another thing I saw, during your time at Rochester is you were, involved with like, there's like a gaming club I wonder if you could talk a little bit about your experience with that. [00:20:55] Sara: Absolutely, I can. So, at RIT, I was an executive board member for three or four years at the Electronic Gaming Society. EGS for short, uh, we hosted weekly console game nights in, the student alumni union area, where there's open space, kind of like a cafeteria. We also hosted quarterly land parties, and we would actually get people from out of state sometimes who weren't even students to come. Uh, and we would usually host the bigger ones in the field house, which is also where concerts are held. And we would hold the smaller ones in conference rooms. I think when I started in 2006, the, the, the LANs were pretty small, maybe like 50, 50 people bring your, your, your huge CRT monitor tower in. [00:21:57] Jeremy: Oh yeah, [00:21:57] Sara: In And then by the time I left in 2012. we were over 300 people for a weekend LAN party, um, and we were actually drawing more power than concerts do. [00:22:13] Jeremy: Incredible. what were, what were people playing at the time? Like when they would the LANs like, [00:22:18] Sara: Yep. Fortnite, early League of Legends, Call of Duty. Battlegrounds. And then also just like fun indie games like Armagedtron, which is kind of like a racing game in the style of [00:22:37] Jeremy: okay. Oh, okay, [00:22:39] Sara: Um, any, there are some like fun browser games where you could just mess with each other. Jackbox. Yeah. [00:22:49] Jeremy: Yeah, it's, it's interesting that, you know, you're talking about stuff like Fortnite and, um, what is it? Battlegrounds is [00:22:55] Sara: not Fortnite. Team Fortress. [00:22:58] Jeremy: Oh Team Fortress! [00:22:59] Sara: Sorry. Yeah. Oh, yeah, I got my, my names mixed up. Fortnite, I think, did not exist at the time, but Team Fortress was big. [00:23:11] Jeremy: Yeah. that's really cool that you're able to get such a big group there. is there something about Rochester, I guess, that that was able to bring together this many people for like these big LAN events? Because I'm... I mean, I'm not sure how it is elsewhere, but I feel like that's probably not what was happening elsewhere in the country. [00:23:31] Sara: Yeah, I mean, if you've ever been to, um, DreamHack, that's, that's a huge LAN party and game convention, that's fun. so... EGS started in the early 2000s, even before I joined, and was just a committed group of people. RIT was a very largely technical school. The majority of students were there for math, science, engineering, or they were in the computer college, [00:24:01] Jeremy: Oh, okay. [00:24:01] Sara: GCIS, G C C I S, the Gossano College of Computing and Information Sciences. So there was a lot of us there. [00:24:10] Jeremy: That does make sense. I mean, it's, it's sort of this, this bias that when there's people doing, uh, technical stuff like software, um, you know, and just IT, [00:24:21] Sara: Mm hmm. [00:24:23] Jeremy: there's kind of this assumption that's like, oh, maybe they play games. And it seems like that was accurate [00:24:27] Sara: It was absolutely accurate. And there were plenty of people that came from different majors. but when I started, there were 17, 000 students and so that's a lot of students and obviously not everyone came to our weekly meetings, but we had enough dedicated people that were on the eboard driving, You know, marketing and advertising for, for our events and things like that, that we were able to get, the good community going. I, I wasn't part of it, but the anime club at RIT is also huge. They run a convention every year that is huge, ToraCon, um. And I think it's just kind of the confluence of there being a lot of geeks and nerds on campus and Rochester is a college town. There's maybe like 10 other universities in [00:25:17] Jeremy: Well, sounds like it was a good time. [00:25:19] Sara: Absolutely would recommend. Strong Museum of Play [00:25:22] Jeremy: I've never, I've never been, but the one thing I have heard about Rochester is there's the, the Strong Museum of Play. [00:25:29] Sara: Yeah, that place is so much fun, even as an adult. It's kind of like, um, the, the Children's Museum in Indiana for, for those that might know that. it just has all the historical toys and pop culture and interactive exhibits. It's so fun. [00:25:48] Jeremy: it's not quite the same, but it, when you were mentioning the Children's Museum in, um, I think it's in St. Louis, there's, uh, it's called the City Museum and it's like a, it's like a giant playground, you know, indoors, outdoors, and it's not just for kids, right? And actually some of this stuff seems like kind of sketch in terms of like, you could kind of hurt yourself, you know, climbing [00:26:10] Sara: When was this made? [00:26:12] Jeremy: I'm not sure, but, uh, [00:26:14] Sara: before regulations maybe. ha. [00:26:16] Jeremy: Yeah. It's, uh, but it's really cool. So at the, at the Museum of Play, though, is it, There's like a video game component, right? But then there's also, like, other types of things, [00:26:26] Sara: Yeah, they have, like, a whole section of the museum that's really, really old toys on display, like, 1900s, 1800s. Um, they have a whole Sesame Street section, and other things like that. Yeah. From Java to Ruby [00:26:42] Jeremy: Check it out if you're in Rochester. maybe now we could talk a little bit about, so like now you're working at Thoughtbot as a Ruby developer. but before we started recording, you were telling me that you started, working with Java. And there was like a, a long path I suppose, you know, changing languages. So maybe you can talk a little bit about your experience there. [00:27:06] Sara: Yeah. for other folks who have switched languages, this might be a familiar story for you, where once you get a job in one technology or one stack, one language, you kind of get typecast after a while. Your next job is probably going to be in the same language, same stack. Companies, they hire based on technology and So, it might be hard, even if you've been playing around with Ruby in your free time, to break, make that barrier jump from one language to another, one stack to another. I mean, these technologies, they can take a little while to ramp up on. They can be a little bit different, especially if you're going from a non object oriented language to an object oriented, don't. Lose hope. (laughs) If you have an interest in Ruby and you're not a Rubyist right now, there's a good company for you that will give you a chance. That's the key that I learned, is as a software developer, the skills that you have that are the most important are not the language that you know. It's the type of thinking that you do, the problem solving, communication, documentation, knowledge sharing, Supporting each other, and as Saron the keynote speaker on Wednesday said, the, the word is love. [00:28:35] Jeremy: [00:28:35] Sara: So when I was job hunting, it was really valuable for me to include those important aspects in my skill, in my resume, in my CV, in my interviews, that like, I'm newer to this language because I had learned it at a rudimentary level before. Never worked in it really professionally for a long time. Um, when I was applying, it was like, look, I'm good at ramping up in technologies. I have been doing software for a long time, and I'm very comfortable with the idea of planning, documenting, problem solving. Give me a chance, please. I was lucky enough to find my place at a company that would give me a chance. Test Double hired me in 2019 as a remote. Software Consultant, and it changed my life. [00:29:34] Jeremy: What, what was it about, Ruby that I'm assuming that this is something that you maybe did in your spare time where you were playing with Ruby or? [00:29:43] Sara: I am one of those people that don't really code in their spare time, which I think is valuable for people to say. The image of a software developer being, well, if you're not coding in your spare time, then you're not passionate about it. That's a myth. That's not true. Some of us, we have other hobbies. I have lots of hobbies. Coding is not the one that I carry outside of the workplace, usually, but, I worked at a company called Constant Contact in 2014 and 2015. And while I was there, I was able to learn Ruby on Rails. [00:30:23] Jeremy: Oh, okay. So that was sort of, I guess, your experience there, on the job. I guess you enjoyed something about the language or something about Rails and then that's what made you decide, like, I would really love to, to... do more of this [00:30:38] Sara: Absolutely. It was amazing. It's such a fun language. The first time I heard about it was in college, maybe 2008 or 2009. And I remember learning, this looks like such a fun language. This looks like it would be so interesting to learn. And I didn't think about it again until 2014. And then I was programming in it. Coming from a Java mindset and it blew my mind, the Rails magic also, I was like, what is happening? This is so cool. Because of my typecasting sort of situation of Java, I wasn't able to get back to it until 2019. And I don't want to leave. I'm so happy. I love the language. I love the community. It's fun. [00:31:32] Jeremy: I can totally see that. I mean, when I first tried out Rails, yeah, it, like, you mentioned the magic, and I know some people are like, ah, I don't like the magic, but when, I think, once I saw what you could do, And how, sort of, little you needed to write, and the fact that so many projects kind of look the same. Um, yeah, that really clicked for me, and I really appreciated that. think that and the Rails console. I think the console is amazing. [00:32:05] Sara: Being able to just check real quick. Hmm, I wonder if this will work. Wait, no, I can check right now. I [00:32:12] Jeremy: And I think that's an important point you brought up too, about, like, not... the, the stereotype and I, I kind of, you know, showed it here where I assumed like, Oh, you were doing Java and then you moved to Ruby. It must've been because you were doing Ruby on the side and thought like, Oh, this is cool. I want to do it for my job. but I, I thought that's really cool that you were able to, not only that you, you don't do the programming stuff outside of work, but that you were able to, to find an opportunity where you could try something different, you know, in your job where you're still being paid. And I wonder, was there any, was there any specific intention behind, like, when you took that job, it was so that I can try something different, or did it just kind of happen? I'm curious what your... The appeal of consulting [00:32:58] Sara: I was wanting to try something different. I also really wanted to get into consulting. [00:33:04] Jeremy: Hmm. [00:33:05] Sara: I have ADHD. And working at a product company long term, I think, was never really going to work out for me. another thing you might notice in my LinkedIn is that a lot of my stays at companies have been relatively short. Because, I don't know, I, my brain gets bored. The consultancy environment is... Perfect. You can go to different clients, different engagements, meet new people, learn a different stack, learn how other people are doing things, help them be better, and maybe every two weeks, two months, three months, six months, a year, change and do it all over again. For some people, that sounds awful. For me, it's perfect. [00:33:51] Jeremy: Yeah, I hadn't thought about that with, with consulting. cause I, I suppose, so you said it's, it's usually about half a year between projects or is It [00:34:01] Sara: varies [00:34:01] Jeremy: It varies widely. [00:34:02] Sara: Widely. I think we try to hit the sweet spot of 3-6 months. For an individual working on a project, the actual contract engagement might be longer than that, but, yeah. Maintainers don't get enough credit [00:34:13] Jeremy: Yeah. And, and your point about how some people, they like to jump on different things and some people like to, to stick to the same thing. I mean, that, that makes a lot of, sense in terms of, I think maintaining software and like building new software. It's, they're both development, [00:34:32] Sara: Mm hmm. [00:34:32] Jeremy: they're very different. Right. [00:34:35] Sara: It's so funny that you bring that up because I highly gravitate towards maintaining over making. I love going to different projects, but I have very little interest in Greenfield, very little interest in making something new. I want to get into the weeds, into 10 years that nobody wants to deal with because the weeds are so high and there's dragons in there. I want to cut it away. I want to add documentation. I want to make it better. It's so important for us to maintain our software. It doesn't get nearly enough credit. The people that work on open source, the people that are doing maintenance work on, on apps internally, externally, Upgrades, making sure dependencies are all good and safe and secure. love that stuff. [00:35:29] Jeremy: That's awesome. We, we need more of you. (laughs) [00:35:31] Sara: There's plenty of us out there, but we don't get the credit (laughs) [00:35:34] Jeremy: Yeah, because it's like with maintenance, well, I would say probably both in companies and in open source when everything is working. Then Nobody nobody knows. Nobody says anything. They're just like, Oh, that's great. It's working. And then if it breaks, then everyone's upset. [00:35:51] Sara: Exactly. [00:35:53] Jeremy: And so like, yeah, you're just there to get yelled at when something goes wrong. But when everything's going good, it's like, [00:35:59] Sara: A job well done is, I was never here. [00:36:02] Jeremy: Yeah. Yeah. Yeah. I don't know how. To, you know, to fix that, I mean, when you think about open source maintainers, right, like a big thing is, is, is burnout, right? Where you are keeping the internet and all of our applications running and, you know, what you get for it is people yelling at you and the issues, right? [00:36:23] Sara: Yeah, it's hard. And I think I actually. Submitted a talk to RubyConf this year about this topic. It didn't get picked. That's okay. Um, we all make mistakes. I'm going to try to give it somewhere in the future, but I think one of the important things that we as an industry should strive for is giving glory. Giving support and kudos to maintenance work. I've been trying to do that. slash I have been doing that at ThoughtBot by, at some cadence. I have been putting out a blog post to the ThoughtBot blog called. This week in open source, the time period that is covered might be a week or longer in those posts. I give a summary of all of the commits that have been made to our open source projects. And the people that made those contributions with highlighting to new version releases, including patch level. And I do this. The time I, I, I took up the torch of doing this from a co worker, Mike Burns, who used to do it 10 years ago. I do this so that people can get acknowledgement for the work they do, even if it's fixing a broken link, even if it's updating some words that maybe don't make sense. All of it is valuable. [00:37:54] Jeremy: Definitely. Yeah. I mean, I, I think that, um, yeah, what's visible to people is when there's a new feature or an API change and Yeah, it's just, uh, people don't, I think a lot of people don't realize, like, how much work goes into just keeping everything running. [00:38:14] Sara: Mm hmm. Especially in the world of open source and Ruby on Rails, all the gems, there's so many different things coming out, things that suddenly this is not compatible. Suddenly you need to change something in your code because a dependency, however many steps apart has changed and it's hard work. The people that do those things are amazing. [00:38:41] Jeremy: So if anybody listening does that work, we, we appreciate you. [00:38:45] Sara: We salute you. Thank you. And if you're interested in contributing to ThoughtBot open source, we have lots of repos. There's one out there for you. Thoughts on RubyConf [00:38:54] Jeremy: You've been doing programming for quite a while, and, you're here at, at RubyConf. I wonder what kind of brings you to these, these conferences? Like, what do you get out of them? Um, I guess, how was this one? That sort of thing. [00:39:09] Sara: Well, first, this one was sick. This one was awesome. Uh, Ruby central pulled out all the stops and that DJ on Monday. In the event, in the exhibit hall. Wow. Amazing. So he told me that he was going to put his set up on Spotify, on Weedmaps Spotify, so go check it out. Anyway, I come to these conferences for people. I just love connecting with people. Those listening might notice that I'm an extrovert. I work remotely. A lot of us work remotely these days. this is an opportunity to see some of my coworkers. There's seven of us here. It's an opportunity to see people I only see at conferences, of which there are a lot. It's a chance to connect with people I've only met on Mastodon, or LinkedIn, or Stack Overflow. It's a chance to meet wonderful podcasters who are putting out great content, keeping our community alive. That's, that's the key for me. And the talks are wonderful, but honestly, they're just a side effect for me. They just come as a result of being here. [00:40:16] Jeremy: Yeah, it's kind of a unique opportunity, you know, to have so many of your, your colleagues and to just all be in the same place. And you know that anybody you talk to here, like if you talk about Ruby or software, they're not going to look at you and go like, I don't know what you're talking about. Like everybody here has at least that in common. So it's, yeah, it's a really cool experience to, to be able to chat with anybody. And it's like, You're all on the same page, [00:40:42] Sara: Mm hmm. We're all in this boat together. [00:40:45] Jeremy: Yup, that we got to keep, got to keep afloat according to matz [00:40:49] Sara: Gotta keep it afloat, yeah. [00:40:51] Jeremy: Though I was like, I was pretty impressed by like during his, his keynote and he had asked, you know, how many of you here, it's your first RubyConf and it felt like it was over half the room. [00:41:04] Sara: Yeah, I got the same sense. I was very glad to see that, very impressed. My first RubyConf was and it was the same sort of showing of [00:41:14] Jeremy: Nice, yeah. Yeah, actually, that was my first one, too. [00:41:17] Sara: Nice! [00:41:19] Jeremy: Uh, that was Nashville, Yeah, yeah, yeah. So it's, yeah, it's really interesting to see because, the meme online is probably like, Ah, Ruby is dead, or Rails is dead. But like you come to these conferences and yeah, there's, there's so many new people. There's like new people that are learning it and experiencing it and, you know, enjoying it the same way we are. So I, I really hope that the, the community can really, yeah, keep this going. [00:41:49] Sara: Continue, continue to grow and share. I love that we had first timer buttons, buttons where people could self identify as this is my first RubyConf and, and then that opens a conversation immediately. It's like, how are you liking it? What was your favorite talk? [00:42:08] Jeremy: Yeah, that's awesome. okay, I think that's probably a good place to start wrapping it. But is there anything else you wanted to mention or thought we should have talked about? [00:42:18] Sara: Can I do a plug for thoughtbot? [00:42:20] Jeremy: yeah, go for it. [00:42:21] Sara: Alright. For those of you out there that might not know what ThoughtBot does, we are a full software lifecycle or company lifecycle consultancy, so we do everything from market fit and rapid prototyping to MVPs to helping with developed companies, developed teams, maybe do a little bit of a Boost when you have a deadline or doing some tech debt. Pay down. We also have a DevOps team, so if you have an idea or a company or a team, you want a little bit of support, we have been around for 20 years. We are here for you. Reach out to us at thoughtbot.com. [00:43:02] Jeremy: I guess the thing about Thoughtbot is that, within the Ruby community specifically, they've been so involved with sponsorships and, and podcasts. And so, uh, when you hear about consultancies, a lot of times it's kind of like, well, I don't know, are they like any good? Do they know what they're doing? But I, I feel like, ThoughtBot has had enough, like enough of a public record. I feel It's like, okay, if you, if you hire them, um, you should be in good hands. [00:43:30] Sara: Yeah. If you have any questions about our abilities, read the blog. [00:43:35] Jeremy: It is a good blog. Sometimes when I'm, uh, searching for how to do something in Rails, it'll pop up, [00:43:40] Sara: Mm hmm. Me too. Every question I ask, one of the first results is our own blog. I'm like, oh yeah, that makes sense. [00:43:47] Jeremy: Probably the peak is if you've written the blog. [00:43:50] Sara: That has happened to my coworkers They're like, wait, I wrote a blog about this nine years ago. [00:43:55] Jeremy: Yeah, yeah. So maybe, maybe that'll happen to you soon. I, I know definitely people who do, um, Stack Overflow. And it's like, Oh, I like, this is a good answer. Oh, I wrote this. (laughs) yeah. Well, Sara, thank you so much for, for chatting with me today. [00:44:13] Sara: Absolutely, Jeremy. Thank you so much for having me. I was really glad to chat today.

David was the chief software architect and director of engineering at Stitch Fix. He's also the author of a number of books including Sustainable Web Development with Ruby on Rails and most recently Ruby on Rails Background Jobs with Sidekiq. He talks about how he made decisions while working with a medium sized team (~200 developers) at Stitch Fix. The audio quality for the first 19 minutes is not great but the correct microphones turn on right after that. Recorded at RubyConf 2023 in San Diego. A few topics covered: Ruby's origins at Stitch Fix Thoughts on Go Choosing technology and cloud services Moving off heroku Building a platform team Where Ruby and Rails fit in today The role of books and how different people learn Large Language Model's effects on technical content Related Links David's Blog Mastodon Transcript You can help correct transcripts on GitHub. Intro [00:00:00] Jeremy: Today. I want to share another conversation from RubyConf San Diego. This time it's with David Copeland. He was a chief software architect and director of engineering at stitch fix. And at the start of the conversation, you're going to hear about why he decided to write the book, sustainable web development with Ruby on rails. Unfortunately, you're also going to notice the sound quality isn't too good. We had some technical difficulties. But once you hit the 20 minute mark of the recording, the mics are going to kick in. It's going to sound way better. So I hope you stick with it. Enjoy. Ruby at Stitch Fix [00:00:35] David: Stitch Fix was a Rails shop. I had done a lot of Rails and learned a lot of things that worked and didn't work, at least in that situation. And so I started writing them down and I was like, I should probably make this more than just a document that I keep, you know, privately on my computer. Uh, so that's, you know, kind of, kind of where the genesis of that came from and just tried to, write everything down that I thought what worked, what didn't work. Uh, if you're in a situation like me. Working on a product, with a medium sized, uh, team, then I think the lessons in there will be useful, at least some of them. Um, and I've been trying to keep it up over, over the years. I think the first version came out a couple years ago, so I've been trying to make sure it's always up to date with the latest stuff and, and Rails and based on my experience and all that. [00:01:20] Jeremy: So it's interesting that you mention, medium sized team because, during the, the keynote, just a few moments ago, Matz the creator of Ruby was talking about how like, Oh, Rails is really suitable for this, this one person team, right? Small, small team. And, uh, he was like, you're not Google. So like, don't worry about, right. Can you scale to that level? Yeah. Um, and, and I wonder like when you talk about medium size or medium scale, like what are, what are we talking? [00:01:49] David: I think probably under 200 developers, I would say. because when I left Stitch Fix, it was closing in on that number of developers. And so it becomes, you know, hard to... You can kind of know who everybody is, or at least the names sound familiar of everybody. But beyond that, it's just, it's just really hard. But a lot of it was like, I don't have experience at like a thousand developer company. I have no idea what that's like, but I definitely know that Rails can work for like... 200 ish people how you can make it work basically. yeah. [00:02:21] Jeremy: The decision to use Rails, I'm assuming that was made before you joined? [00:02:26] David: Yeah, the, um, the CTO of Stitch Fix, he had come in to clean up a mess made by contractors, as often happens. They had used Django, which is like the Python version of Rails. And he, the CTO, he was more familiar with Rails. So the first two developers he hired, also familiar with Rails. There wasn't a lot to maintain with the Django app, so they were like, let's just start fresh, fresh with Rails. yeah, but it's funny because a lot of the code in that Rails app was, like, transliterated from Python. So you could, it would, it looked like the strangest Ruby code in the world because it was basically, there was no test. So they were like, let's just write the Ruby version of this Python just so we know it works. but obviously that didn't, didn't last forever, so. [00:03:07] Jeremy: So, so what's an example of a, of a tell? Where you're looking at the code and you're like, oh, this is clearly, it came from Python. [00:03:15] David: You'd see like, very, very explicit, right? Like Python, there's a lot of like single line things. very like, this sounds like a dig, but it's very simple looking code. Like, like I don't know Python, but I was able to change this Django app. And I had to, I could look at it and you can figure out immediately how it works. Cause there's. Not much to it. There's nothing fancy. So, like, this, this Ruby code, there was nothing fancy. You'd be like, well, maybe they should have memoized that, or maybe they should have taken that into another class, or you could have done this with a hash or something like that. So there was, like, none of that. It was just, like, really basic, plain code like you would see in any beginning programming language kind of thing. Which is at least nice. You can understand it. but you probably wouldn't have written it that way at first in Ruby. Thoughts on Go [00:04:05] Jeremy: Yeah, that's, that's interesting because, uh, people sometimes talk about the Go programming language and how it looks, I don't know if simple is the right word, but it's something where you look at the code and even if you don't necessarily understand Go, it's relatively straightforward. Yeah. I wonder what your thoughts are on that being a strength versus that being, like, [00:04:25] David: Yeah, so at Stitch Fix at one point we had a pro, we were moving off of Heroku and we were going to, basically build a deployment platform using ECS on AWS. And so the deployment platform was a Rails app and we built a command line tool using Ruby. And it was fine, but it was a very complicated command line tool and it was very slow. And so one of the developers was like, I'm going to rewrite it in Go. I was like, ugh, you know, because I just was not a big fan. So he rewrote it in Go. It was a bazillion times faster. And then I was like, okay, I'm going to add, I'll add a feature to it. It was extremely easy. Like, it's just like what you said. I looked at it, like, I don't know anything about Go. I know what is happening here. I can copy and paste this and change things and make it work for what I want to do. And it did work. And it was, it was pretty easy. so there's that, I mean, aesthetically it's pretty ugly and it's, I, I. I can't really defend that as a real reason to not use it, but it is kind of gross. I did do Go, I did a small project in Go after Stitch Fix, and there's this vibe in Go about like, don't create abstractions. I don't know where I got that from, but every Go I look at, I'm like we should make an abstraction for this, but it's just not the vibe. They just don't like doing that. They like it all written out. And I see the value because you can look at the code and know what it does and you don't have to chase abstractions anywhere. But. I felt like I was copying and pasting a lot of, a lot of things. Um, so I don't know. I mean, the, the team at Stitch Fix that did this like command line app in go, they're the platform team. And so their job isn't to write like web apps all day, every day. There's kind of in and out of all kinds of things. They have to try to figure out something that they don't understand quickly to debug a problem. And so I can see the value of something like go if that's your job, right? You want to go in and see what the issue is. Figure it out and be done and you're not going to necessarily develop deep expertise and whatever that thing is that you're kind of jumping into. Day to day though, I don't know. I think it would make me kind of sad. (laughs) [00:06:18] Jeremy: So, so when you say it would make you kind of sad, I mean, what, what about it? Is it, I mean, you mentioned that there's a lot of copy and pasting, so maybe there's code duplication, but are there specific things where you're like, oh, I just don't? [00:06:31] David: Yeah, so I had done a lot of Java in my past life and it felt very much like that. Where like, like the Go library for making an HTTP call for like, I want to call some web service. It's got every feature you could ever want. Everything is tweakable. You can really, you can see why it's designed that way. To dial in some performance issue or solve some really esoteric thing. It's there. But the problem is if you just want to get an JSON, it's just like huge production. And I felt like that's all I really want to do and it's just not making it very easy. And it just felt very, very cumbersome. I think that having to declare types also is a little bit of a weird mindset because, I mean, I like to make types in Ruby, I like to make classes, but I also like to just use hashes and stuff to figure it out. And then maybe I'll make a class if I figure it out, but Go, you can't. You have to have a class, you have to have a type, you have to think all that ahead of time, and it just, I'm not used to working that way, so it felt, I mean, I guess I could get used to it, but I just didn't warm up to that sort of style of working, so it just felt like I was just kind of fighting with the vibe of the language, kind of. Yeah, [00:07:40] Jeremy: so it's more of the vibe or the feel where you're writing it and you're like this seems a little too... Explicit. I feel like I have to be too verbose. It just doesn't feel natural for me to write this. [00:07:53] David: Right, it's not optimized for what in my mind is the obvious case. And maybe that's not the obvious case for the people that write Go programs. But for me, like, I just want to like get this endpoint and get the JSON back as a map. Not any easier than any other case, right? Whereas like in Ruby, right? And you can, I think if you include net HTTP, you can just type get. And it will just return whatever that is. Like, that's amazing. It's optimized for what I think is a very common use case. So it makes me feel really productive. It makes me feel pretty good. And if that doesn't work out long term, I can always use something more complicated. But I'm not required to dig into the NetHttp library just to do what in my mind is something very simple. [00:08:37] Jeremy: Yeah, I think that's something I've noticed myself in working with Ruby. I mean, you have the standard library that's very... Comprehensive and the API surface is such that, like you said there, when you're trying to do common tasks, a lot of times they have a call you make and it kind of does the thing you expected or hoped for. [00:08:56] David: Yeah, yeah. It's kind of, I mean, it's that whole optimized for programmer happiness thing. Like it does. That is the vibe of Ruby and it seems like that is still the way things are. And, you know, I, I suppose if I had a different mindset, I mean, because I work with developers who did not like using Ruby or Rails. They loved using Go or Java. And I, I guess there's probably some psychological analysis we could do about their background and history and mindset that makes that make sense. But, to me, I don't know. It's, it's nice when it's pleasant. And Ruby seems pleasant. (laughs) Choosing Technology [00:09:27] Jeremy: as a... Software Architect, or as a CTO, when, when you're choosing technology, what are some of the things you look at in terms of, you know? [00:09:38] David: Yeah, I mean, I think, like, it's a weird criteria, but I think what is something that the team is capable of executing with? Because, like, most, right, most programming languages all kind of do the same thing. Like, you can kind of get most stuff done in most common popular programming languages. So, it's probably not... It's not true that if you pick the wrong language, you can't build the app. Like, that's probably not really the case. At least for like a web app or something. so it's more like, what is the team that's here to do it? What are they comfortable and capable of doing? I worked on a project with... It was a mix of like junior engineers who knew JavaScript, and then some senior engineers from Google. And for whatever reason someone had chosen a Rails app and none of them were comfortable or really yet competent with doing Ruby on Rails and they just all hated it and like it didn't work very well. Um, and so even though, yes, Rails is a good choice for doing stuff for that team at that moment. Not a good choice. Right. So I think you have to go in and like, what, what are we going to be able to execute on so that when the business wants us to do something, we just do it. And we don't complain and we don't say, Oh, well we can't because this technology that we chose, blah, blah, blah. Like you don't ever want to say that if possible. So I think that's. That's kind of the, the top thing. I think second would be how widely supported is it? Like you don't want to be the cutting edge user that's finding all the bugs in something really. Like you want to use something that's stable. Postgres, MySQL, like those work, those are fine. The bugs have been sorted out for most common use cases. Some super fancy edge database, I don't know if I'd want to be doing, doing that you know? Choosing cloud services [00:11:15] Jeremy: How do you feel about the cloud specific services and databases? Like are you comfortable saying like, oh, I'm going to use... Google Cloud, BigQuery. Yeah. [00:11:27] David: That sort of thing. I think it would kind of fall under the same criteria that I was just, just saying like, so with AWS it's interesting 'cause when we moved from Heroku to AWS by EC2 RDS, their database thing, uh, S3, those have been around for years, probably those are gonna work, but they always introduce new things. Like we, we use RabbitMQ and AWS came out with. Some, I forget what it was, it was a queuing service similar to Rabbit. We were like, Oh, maybe we should switch to that. But it was clear that they weren't really ready to support it. So. Yeah, so we didn't, we didn't switch to that. So I, you gotta try to read the tea leaves of the provider to see are they committed to, to supporting this thing or is this there to get some enterprise client to move into the cloud. And then the idea is to move off of that transitional thing into what they do support. And it's hard to get a clear answer from them too. So it takes a little bit of research to figure out, Are they going to support this or not? Because that's what you don't want. To move everything into some very proprietary cloud system and have them sunset it and say, Oh yeah, now you've got to switch again. Uh, that kind of sucks. So, it's a little trickier. [00:12:41] Jeremy: And what kind of questions or research do you do? Is it purely a function of this thing has existed for X number of years so I feel okay? [00:12:52] David: I mean, it's kind of similar to looking at like some gem you're going to add to your project, right? So you'll, you'll look at how often does it change? Is it being updated? Uh, what is the documentation? Does it look like someone really cared about the documentation? Does the documentation look updated? Are there issues with it that are being addressed or, or not? Um, so those are good signals. I think, talking to other practitioners too can be good. Like if you've got someone who's experienced. You can say, hey, do you know anybody back channeling through, like, everybody knows somebody that works at AWS, you can probably try to get something there. at Stitch Fix, we had an enterprise support contract, and so your account manager will sometimes give you good information if you ask. Again, it's a, they're not going to come out and say, don't use this product that we have, but they might communicate that in a subtle way. So you have to triangulate from all these sources to try to. to try to figure out what, what you want to do. [00:13:50] Jeremy: Yeah, it kind of makes me wish that there was a, a site like, maybe not quite like, can I use, right? Can I use, you can see like, oh, can I use this in my browser? Is there, uh, like an AWS or a Google Cloud? Can I trust this? Can I trust this? Yeah. Is this, is this solid or not? [00:14:04] David: Right, totally. It's like, there's that, that site where you, it has all the Apple products and it says whether or not you should buy it because one may or may not be coming out or they may be getting rid of it. Like, yeah, that would... For cloud services, that would be, that would be nice. [00:14:16] Jeremy: Yeah, yeah. That's like the Mac Buyer's Guide. And then we, we need the, uh, the technology. Yeah. Maybe not buyers. Cloud Provider Buyer's Guide, yeah. I guess we are buyers. [00:14:25] David: Yeah, yeah, totally, totally. [00:14:27] Jeremy: it's interesting that you, you mentioned how you want to see that, okay, this thing is mature. I think it's going to stick around because, I, interviewed, someone who worked on, I believe it was the CloudWatch team. Okay. Daniel Vassalo, yeah. so he left AWS, uh, after I think about 10 years, and then he wrote a book called, uh, The Good Parts of AWS. Oh! And, if you read his book, most of the services he says to use are the ones that are, like, old. Yeah. He's, he's basically saying, like, S3, you know you're good. Yeah. Right? but then all these, if you look at the AWS webpage, they have who knows, I don't know how many hundreds of services. Yeah. He's, he's kind of like I worked there and I would not use, you know, all these new services. 'cause I myself, I don't trust [00:15:14] David: it yet. Right. And so, and they're working there? Yeah, they're working there. Yeah. No. One of the VPs at Stitch Fix had worked on Google Cloud and so when we were doing this transition from Heroku, he was like, we are not using Google Cloud. I was like, really? He's like AWS is far ahead of the game. Do not use Google Cloud. I was like, all right, I don't need any more info. You work there. You said don't. I'm gonna believe you. So [00:15:36] Jeremy: what, what was his did he have like a core point? [00:15:39] David: Um, so he never really had anything bad to say about Google per se. Like I think he enjoyed his time there and I think he thought highly of who he worked with and what he worked on and that sort of thing. But his, where he was coming from was like AWS was so far ahead. of Google on anything that we would use, he was like, there's, there's really no advantage to, to doing it. AWS is a known quantity, right? it's probably still the case. It's like, you know, you've heard the nobody ever got fired for using IBM or using Microsoft or whatever the thing is. Like, I think that's, that was kind of the vibe. And he was like, moving all of our infrastructure right before we're going to go public. This is a serious business. We should just use something that we know will work. And he was like, I know this will work. I'm not confident about. Google, uh, for our use case. So we shouldn't, we shouldn't risk it. So I was like, okay, I trust you because I didn't know anything about any of that stuff at the time. I knew Heroku and that was it. So, yeah. [00:16:34] Jeremy: I don't know if it's good or bad, but like you said, AWS seems to be the default choice. Yeah. And I mean, there's people who use Azure. I assume it's mostly primarily Microsoft. Yeah. And then there's Google Cloud. It's not really clear why you would pick it, unless there was a specific service or something that only they had. [00:16:55] David: Yeah, yeah. Or you're invested in Google, you know, you want to keep everything there. I mean, I don't know. I haven't really been at that level to make that kind of decision, and I would probably choose AWS for the reasons discussed, but, yeah. Moving off Heroku [00:17:10] Jeremy: And then, so at Stitch Fix, you said you moved off of Heroku [00:17:16] David: yeah. Yeah, so we were heavy into Heroku. I think that we were told that at one point we had the biggest Heroku Postgres database on their platform. Not a good place to be, right? You never want to be the biggest customer person, usually. but the problem we were facing was essentially we were going to go public. And to do that, you're under all the scrutiny. about many things, including the IT systems and the security around there. So, like, by default, a Postgres, a Heroku Postgres database is, like, on the internet. It's only secured by the password. all their services are on the internet. So, not, not ideal. they were developing their private cloud service at that time. And so that would have given us, in theory, on paper, it would have solved all of our problems. And we liked Heroku and we liked the developer experience. It was great. but... Heroku private spaces, it was still early. There's a lot of limitations that when they explained why those limitations, they were reasonable. And if we had. started from scratch on Heroku Private Spaces. It probably would have worked great, but we hadn't. So we just couldn't make it work. So we were like, okay, we're going to have to move to AWS so that everything can be basically off the internet. Like our public website needs to be on the internet and that's kind of it. So we need to, so that's basically was the, was the impetus for that. but it's too bad because I love Heroku. It was great. I mean, they were, they were a great partner. They were great. I think if Stitch Fix had started life a year later, Private Spaces. Now it's, it's, it's way different than it was then. Cause it's been, it's a mature product now, so we could have easily done that, but you know, the timing didn't work out, unfortunately. [00:18:50] Jeremy: And that was a compliance thing to, [00:18:53] David: Yeah. And compliance is weird cause they don't tell you what to do, but they give you some parameters that you need to meet. And so one of them is like how you control access. So, so going public, the compliance is around the financial data and. Ensuring that the financial data is accurate. So a lot of the systems at Stichfix were storing the financial data. We, you know, the warehouse management system was custom made. Uh, all the credit card processing was all done, like it was all in some databases that we had running in Heroku. And so those needed to be subject to stricter security than we could achieve with just a single password that we just had to remember to rotate when someone like left the team. So that was, you know, the kind of, the kind of impetus for, for all of that. [00:19:35] Jeremy: when you were using Heroku, Salesforce would have already owned it then. Did you, did you get any sense that you weren't really sure about the future of the platform while you're on it or, [00:19:45] David: At that time, no, it seemed like they were still innovating. So like, Heroku has a Redis product now. They didn't at the time we wish that they did. They told us they're working on it, but it wasn't ready. We didn't like using the third parties. Kafka was not a thing. We very much were interested in that. We would have totally used it if it was there. So they were still. Like doing bigger innovations then, then it seems like they are now. I don't know. It's weird. Like they're still there. They still make money, I assume for Salesforce. So it doesn't feel like they're going away, but they're not innovating at the pace that they were kind of back in the day. [00:20:20] Jeremy: it used to feel like when somebody's asking, I want to host a Rails app. Then you would say like, well, use Heroku because it's basically the easiest to get started. It's a known quantity and it's, it's expensive, but, it seemed for, for most people, it was worth it. and then now if I talk to people, it's like. Not what people suggest anymore. [00:20:40] David: Yeah, because there's, there's actual competitors. It's crazy to me that there was no competitors for years, and now there's like, Render and Fly. io seem to be the two popular alternatives. Um, I doubt they're any cheaper, honestly, but... You get a sense, right, that they're still innovating, still building those platforms, and they can build with, you know, all of the knowledge of what has come before them, and do things differently that might, that might help. So, I still use Heroku for personal things just because I know it, and I, you know, sometimes you don't feel like learning a new thing when you just want to get something done, but, yeah, I, I don't know if we were starting again, I don't know, maybe I'd look into those things. They, they seem like they're getting pretty mature and. Heroku's resting on its laurels, still. [00:21:26] Jeremy: I guess I never quite the mindset, right? Where you You have a platform that's doing really well and people really like it and you acquire it and then it just It seems like you would want to keep it rolling, right? (laughs) [00:21:38] David: Yeah, it's, it is wild, I mean, I guess... Why did you, what was Salesforce thinking they were going to get? Uh, who knows maybe the person at Salesforce that really wanted to purchase it isn't there. And so no one at Salesforce cares about it. I mean, there's all these weird company politics that like, who knows what's going on and you could speculate. all day. What's interesting is like, there's definitely some people in the Ruby community who work there and still are working there. And that's like a little bit of a canary for me. I'm like, all right, well, if that person's still working there, that person seems like they're on the level and, and, and, and seems pretty good. They're still working there. It, it's gotta be still a cool place to be or still doing something, something good. But, yeah, I don't know. I would, I would love to know what was going on in all the Salesforce meetings about acquiring that, how to manage it. What are their plans for it? I would love to know that stuff. [00:22:29] Jeremy: maybe you had some experience with this at Stitch Fix But I've heard with Heroku some of their support staff at least in the past they would, to some extent, actually help you troubleshoot, like, what's going on with your app. Like, if your app is, like, using a whole bunch of memory, and you're out of memory, um, they would actually kind of look into that, for you, which is interesting, because it's like, that's almost like a services thing than it is just a platform. [00:22:50] David: Yeah. I mean, they, their support, you would get, you would get escalated to like an engineer sometimes, like who worked on that stuff and they would help figure out what the problem was. Like you got the sense that everybody there really wanted the platform to be good and that they were all sort of motivated to make sure that everybody. You know, did well and used the platform. And they also were good at, like a thing that trips everybody up about Heroku is that your app restarts every day. And if you don't know anything about anything, you might think that is stupid. Why, why would I want that? That's annoying. And I definitely went through that and I complained to them a lot. And I'm like, if you only could not restart. And they very patiently and politely explained to me why that it needed to do that, they weren't going to remove that, and how to think about my app given that reality, right? Which is great because like, what company does that, right? From the engineers that are working on it, like No, nobody does that. So, yeah, no, I haven't escalated anything to support at Heroku in quite some time, so I don't know if it's still like that. I hope it is, but I'm not really, not really sure. Building a platform team [00:23:55] Jeremy: Yeah, that, uh, that reminds me a little bit of, I think it's Rackspace? There's, there's, like, another hosting provider that was pretty popular before, and they... Used to be famous for that type of support, where like your, your app's having issues and somebody's actually, uh, SSHing into your box and trying to figure out like, okay, what's going on? which if, if that's happening, then I, I can totally see where the, the price is justified. But if the support is kind of like dropping off to where it's just, they don't do that kind of thing, then yeah, I can see why it's not so much of a, yeah, [00:24:27] David: We used to think of Heroku as like they were the platform team before we had our own platform team and they, they acted like it, which was great. [00:24:35] Jeremy: Yeah, I don't have, um, experience with, render, but I, I, I did, talk to someone from there, and it does seem like they're, they're trying to fill that role, um, so, yeah, hopefully, they and, and other companies, I guess like Vercel and things like that, um, they're, they're all trying to fill that space, [00:24:55] David: Yeah, cause, cause building our own internal platform, I mean it was the right thing to do, but it's, it's a, you can't just, you have to have a team on it, it's complicated, getting all the stuff in AWS to work the way you want it to work, to have it be kind of like Heroku, like it's not trivial. if I'm a one person company, I don't want to be messing around with that particularly. I want to just have it, you know, push it up and have it go and I'm willing to pay for that. So it seems logical that there would be competitors in that space. I'm glad there are. Hopefully that'll light a fire under, under everybody. [00:25:26] Jeremy: so in your case, it sounds like you moved to having your own platform team and stuff like that, uh, partly because of the compliance thing where you're like, we need our, we need to be isolated from the internet. We're going to go to AWS. If you didn't have that requirement, do you still think like that would have been the time to, to have your own platform team and manage that all yourself? [00:25:46] David: I don't know. We, we were thinking an issue that we were running into when we got bigger, um, was that, I mean, Heroku, it, It's obviously not as flexible as AWS, but it is still very flexible. And so we had a lot of internal documentation about this is how you use Heroku to do X, Y, and Z. This is how you set up a Stitch Fix app for Heroku. Like there was just the way that we wanted it to be used to sort of. Just make it all manageable. And so we were considering having a team spun up to sort of add some tooling around that to sort of make that a little bit easier for everybody. So I think there may have been something around there. I don't know if it would have been called a platform team. Maybe we call, we thought about calling it like developer happiness or because you got developer experience or something. We, we probably would have had something there, but. I do wonder how easy it would have been to fund that team with developers if we hadn't had these sort of business constraints around there. yeah, um, I don't know. You get to a certain size, you need some kind of manageability and consistency no matter what you're using underneath. So you've got to have, somebody has to own it to make sure that it's, that it's happening. [00:26:50] Jeremy: So even at your, your architect level, you still think it would have been a challenge to, to. Come to the executive team and go like, I need funding to build this team. [00:27:00] David: You know, certainly it's a challenge because everybody, you know, right? Nobody wants to put developers in anything, right? There are, there are a commodity and I mean, that is kind of the job of like, you know, the staff engineer or the architect at a company is you don't have, you don't have the power to put anybody on anything you, you have the power to Schedule a meeting with a VP or the CTO and they will listen to you. And that's basically, you've got to use that power to convince them of what you want done. And they're all reasonable people, but they're balancing 20 other priorities. So it would, I would have had to, it would have been a harder case to make that, Hey, I want to take three engineers. And have them write tooling to make Heroku easier to use. What? Heroku is not easy to use. Why aren't, you know, so you really, I would, it would be a little bit more of a stretch to walk them through it. I think a case could be made, but, definitely would take some more, more convincing than, than what was needed in our case. [00:27:53] Jeremy: Yeah. And I guess if you're able to contrast that with, you were saying, Oh, I need three people to help me make Heroku easier. Your actual platform team on AWS, I imagine was much larger, right? [00:28:03] David: Initially it was, there was, it was three people did the initial move over. And so by the time we went public, we'd been on this new system for, I don't know, six to nine months. I can't remember exactly. And so at that time the platform team was four or five people, and I, I mean, so percentage wise, right, the engineering team was maybe almost 200, 150, 200. So percentage wise, maybe a little small, I don't know. but it kind of gets back to the power of like the rails and the one person framework. Like everything we did was very much the same And so the Rails app that managed the deployment was very simple. The, the command line app, even the Go one with all of its verbosity was very, very simple. so it was pretty easy for that small team to manage. but, Yeah, so it was sort of like for redundancy, we probably needed more than three or four people because you know, somebody goes out sick or takes a vacation. That's a significant part of the team. But in terms of like just managing the complexity and building it and maintaining it, like it worked pretty well with, you know, four or five people. Where Rails fits in vs other technology [00:29:09] Jeremy: So during the Keynote today, they were talking about how companies like GitHub and Shopify and so on, they're, they're using Rails and they're, they're successful and they're fairly large. but I think the thing that was sort of unsaid was the fact that. These companies, while they use Rails, they use a lot of other, technology as well. And, and, and kind of increasing amounts as well. So, I wonder from your perspective, either from your experience at StitchFix or maybe going forward, what is the role that, that Ruby and Rails plays? Like, where does it make sense for that to be used versus like, Okay, we need to go and build something in Java or, you know, or Go, that sort of thing? [00:29:51] David: right. I mean, I think for like your standard database backed web app, it's obviously great. especially if your sort of mindset bought into server side rendering, it's going to be great at that. so like internal tools, like the customer service dashboard or... You know, something for like somebody who works at a company to use. Like, it's really great because you can go super fast. You're not going to be under a lot of performance constraints. So you kind of don't even have to think about it. Don't even have to solve it. You can, but you don't have to, where it wouldn't work, I guess, you know, if you have really strict performance. Requirements, you know, like a, a Go version of some API server is going to use like percentages of what, of what Rails would use. If that's meaningful, if what you're spending on memory or compute is, is meaningful, then, then yeah. That, that becomes worthy of consideration. I guess if you're, you know, if you're making a mobile app, you probably need to make a mobile app and use those platforms. I mean, I guess you can wrap a Rails app sort of, but you're still making, you still need to make a mobile app, that does something. yeah. And then, you know, interestingly, the data science part of Stitch Fix was not part of the engineering team. They were kind of a separate org. I think Ruby and Rails was probably the only thing they didn't use over there. Like all the ML stuff, everything is either Java or Scala or Python. They use all that stuff. And so, yeah, if you want to do AI and ML with Ruby, you, it's, it's hard cause there's just not a lot there. You really probably should use Python. It'll make your life easier. so yeah, those would be some of the considerations, I guess. [00:31:31] Jeremy: Yeah, so I guess in the case of, ML, Python, certainly, just because of the, the ecosystem, for maybe making a command line application, maybe Go, um, Go or Rust, perhaps, [00:31:44] David: Right. Cause you just get a single binary. Like the problem, I mean, I wrote this book on Ruby command line apps and the biggest problem is like, how do I get the Ruby VM to be anywhere so that it can then run my like awesome scripts? Like that's kind of a huge pain. (laughs) So [00:31:59] Jeremy: and then you said, like, if it's Very performance sensitive, which I am kind of curious in, in your experience with the companies you've worked at, when you're taking on a project like that, do you know up front where you're like, Oh, the CPU and memory usage is going to be a problem, or is it's like you build it and you're like, Oh, this isn't working. So now I know. [00:32:18] David: yeah, I mean, I, I don't have a ton of great experience there at Stitch Fix. The biggest expense the company had was the inventory. So like the, the cost of AWS was just de minimis compared to all that. So nobody ever came and said, Hey, you've got to like really save costs on, on that stuff. Cause it just didn't really matter. at the, the mental health startup I was at, it was too early. But again, the labor costs were just far, far exceeded the amount of money I was spending on, on, um, you know, compute and infrastructure and stuff like that. So, Not knowing anything, I would probably just sort of wait and see if it's a problem. But I suppose you always take into account, like, what am I actually building? And like, what does this business have to scale to, to make it worthwhile? And therefore you can kind of do a little bit of planning ahead there. But, I dunno, I think it would kind of have to depend. [00:33:07] Jeremy: There's a sort of, I guess you could call it a meme, where people say like, Oh, it's, it's not, it's not Rails that's slow, it's the, the database that's slow. And, uh, I wonder, is that, is that accurate in your experience, or, [00:33:20] David: I mean, most of the stuff that we had that was slow was the database, because like, it's really easy to write a crappy query in Rails if you're not, if you're not careful, and then it's really easy to design a database that doesn't have any indexes if you're not careful. Like, you, you kind of need to know that, But of course, those are easy to fix too, because you just add the index, especially if it's before the database gets too big where we're adding indexes is problematic. But, I think those are just easy performance mistakes to make. Uh, especially with Rails because you're not, I mean, a lot of the Rails developers at Citrix did not know SQL at all. I mean, they had to learn it eventually, but they didn't know it at all. So they're not even knowing that what they're writing could possibly be problematic. It's just, you're writing it the Rails way and it just kind of works. And at a small scale, it does. And it doesn't matter until, until one day it does. [00:34:06] Jeremy: And then in, in the context of, let's say, using ActiveRecord and instantiating the objects, or, uh, the time it takes to render templates, that kinds of things, to, at least in your experience, that wasn't such of an issue. [00:34:20] David: No, and it was always, I mean, whenever we looked at why something was slow, it was always the database and like, you know, you're iterating over some active records and then, and then, you know, you're going into there and you're just following this object graph. I've got a lot of the, a lot of the software at Stitch Fix was like internal stuff and it was visualizing complicated data out of the database. And so if you didn't think about it, you would just start dereferencing and following those relationships and you have this just massive view and like the HTML is fine. It's just that to render this div, you're. Digging into some active record super deep. and so, you know, that was usually the, the, the problems that we would see and they're usually easy enough to fix by making an index or. Sometimes you do some caching or something like that. and that solved most of the, most of the issues [00:35:09] Jeremy: The different ways people learn [00:35:09] Jeremy: so you're also the author of the book, Sustainable Web Development with Ruby on Rails. And when you talk to people about like how they learn things, a lot of them are going on YouTube, they're going on, uh, you know, looking for blogs and things like that. And so as an author, what do you think the role is of, of books now? Yeah, [00:35:29] David: I have thought about this a lot, because I, when I first got started, I'm pretty old, so books were all you had, really. Um, so they seem very normal and natural to me, but... does someone want to sit down and read a 400 page technical book? I don't know. so Dave Thomas who runs Pragmatic Bookshelf, he was on a podcast and was asked the same question and basically his answer, which is my answer, is like a long form book is where you can really lay out your thinking, really clarify what you mean, really take the time to develop sometimes nuanced, examples or nuanced takes on something that are Pretty hard to do in a short form video or in a blog post. Because the expectation is, you know, someone sends you an hour long YouTube video, you're probably not going to watch that. Two minute YouTube video is sure, but you can't, you can't get into so much, kind of nuanced detail. And so I thought that was, was right. And that was kind of my motivation for writing. I've got some thoughts. They're too detailed. It's, it's too much set up for a blog post. There's too much of a nuanced element to like, really get across. So I need to like, write more. And that means that someone's going to have to read more to kind of get to it. But hopefully it'll be, it'll be valuable. one of the sessions that we're doing later today is Ruby content creators, where it's going to be me and Noel Rappin and Dave Thomas representing the old school dudes that write books and probably a bunch of other people that do, you know, podcasts videos. It'd be interesting to see, I really want to know how do people learn stuff? Because if no one reads books to learn things, then there's not a lot of point in doing it. But if there is value, then, you know. It should be good and should be accessible to people. So, that's why I do it. But I definitely recognize maybe I'm too old and, uh, I'm not hip with the kids or, or whatever, whatever the case is. I don't know. [00:37:20] Jeremy: it's tricky because, I think it depends on where you are in the process of learning that thing. Because, let's say, you know a fair amount about the technology already. And you look at a book, in a lot of cases it's, it's sort of like taking you from nothing to something. And so you're like, well, maybe half of this isn't relevant to me, but then if I don't read it, then I'm probably missing a lot still. And so you're in this weird in be in between zone. Another thing is that a lot of times when people are trying to learn something, they have a specific problem. And, um, I guess with, with books, it's, you kind of don't know for sure if the thing you're looking for is going to be in the book. [00:38:13] David: I mean, so my, so my book, I would not say as a beginner, it's not a book to learn how to do Rails. It's like you already kind of know Rails and you want to like learn some comprehensive practices. That's what my book is for. And so sometimes people will ask me, I don't know Rails, should I get your book? And I'm like, no, you should not. but then you have the opposite thing where like the agile web development with Rails is like the beginner version. And some people are like, Oh, it's being updated for Rails 7. Should I get it? I'm like, probably not because How to go from zero to rails hasn't changed a lot in years. There's not that much that's going to be new. but, how do you know that, right? Hopefully the Table of Contents tells you. I mean, the first book I wrote with Pragmatic, they basically were like, The Table of Contents is the only thing the reader, potential reader is going to have to have any idea what's in the book. So, You need to write the table of contents with that in mind, which may not be how you'd write the subsections of a book, but since you know that it's going to serve these dual purposes of organizing the book, but also being promotional material that people can read, you've got to keep that in mind, because otherwise, how does anybody, like you said, how does anybody know what's, what's going to be in there? And they're not cheap, I mean, these books are 50 bucks sometimes, and That's a lot of money for people in the U. S. People outside the U. S. That's a ton of money. So you want to make sure that they know what they're getting and don't feel ripped off. [00:39:33] Jeremy: Yeah, I think the other challenge is, at least what I've heard, is that... When people see a video course, for whatever reason, they, they set, like, a higher value to it. They go, like, oh, this video course is, 200 dollars and it's, like, seems like a lot of money, but for some people it's, like, okay, I can do that. But then if you say, like, oh, this, this book I've been researching for five years, uh, I want to sell it for a hundred bucks, people are going to be, like no. No way., [00:40:00] David: Yeah. Right. A hundred bucks for a book. There's no way. That's a, that's a lot. Yeah. I mean, producing video, I've thought about doing video content, but it seems so labor intensive. Um, and it's kind of like, It's sort of like a performance. Like I was mentioning before we started that I used to play in bands and like, there's a lot to go into making an even mediocre performance. And so I feel like, you know, video content is the same way. So I get that it like, it does cost more to produce, but, are you getting more information out of it? I, that, I don't know, like maybe not, but who knows? I mean, people learn things in different ways. So, [00:40:35] Jeremy: It's just like this perception thing, I think. And, uh, I'm not sure why that is. Um, [00:40:40] David: Yeah, maybe it's newer, right? Maybe books feel older so they're easier to make and video seems newer. I mean, I don't know. I would love to talk to engineers who are like... young out of college, a few years into their career to see what their perception of this stuff is. Cause I mean, there was no, I mean, like I said, I read books cause that's all there was. There was no, no videos. You, you go to a conference and you read a book and that was, that was all you had. so I get it. It seems a whole video. It's fancier. It's newer. yeah, I don't know. I would love to hear a wide variety of takes on it to see what's actually the, the future, you know? [00:41:15] Jeremy: sure, yeah. I mean, I think it probably can't just be one or the other, right? Like, I think there are... Benefits of each way. Like, if you have the book, you can read it at your own pace without having to, like, scroll through the video, and you can easily copy and paste the, the code segments, [00:41:35] David: Search it. Go back and forth. [00:41:36] Jeremy: yeah, search it. So, I think there's a place for it, but yeah, I think it would be very interesting, like you said, to, to see, like, how are people learning, [00:41:45] David: Right. Right. Yeah. Well, it's the same with blogs and podcasts. Like I, a lot of podcasters I think used to be bloggers and they realized that like they can get out what they need by doing a podcast. And it's way easier because it's more conversational. You don't have to do a bunch of research. You don't have to do a bunch of editing. As long as you're semi coherent, you can just have a conversation with somebody and sort of get at some sort of thing that you want to talk about or have an opinion about. And. So you, you, you see a lot more podcasts and a lot less blogs out there because of that. So it's, that's kind of like the creators I think are kind of driving that a little bit. yeah. So I don't know. [00:42:22] Jeremy: Yeah, I mean, I can, I can say for myself, the thing about podcasts is that it's something that I can listen to while I'm doing something else. And so you sort of passively can hopefully pick something up out of that conversation, but... Like, I think it's maybe not so good at the details, right? Like, if you're talking code, you can talk about it over voice, but can you really visualize it? Yeah, yeah, yeah. I think if you sit down and you try to implement something somebody talked about, you're gonna be like, I don't know what's happening. [00:42:51] David: Yeah. [00:42:52] Jeremy: So, uh, so, so I think there's like these, these different roles I think almost for so like maybe you know the podcast is for you to Maybe get some ideas or get some familiarity with a thing and then when you're ready to go deeper You can go look at a blog post or read a book I think video kind of straddles those two where sometimes video is good if you want to just see, the general concept of a thing, and have somebody explain it to you, maybe do some visuals. that's really good. but then it can also be kind of detailed, where, especially like the people who stream their process, right, you can see them, Oh, let's, let's build this thing together. You can ask me questions, you can see how I think. I think that can be really powerful. at the same time, like you said, it can be hard to say, like, you know, I look at some of the streams and it's like, oh, this is a three hour stream and like, well, I mean, I'm interested. I'm interested, but yeah, it's hard enough for me to sit through a, uh, a three hour movie, [00:43:52] David: Well, then that, and that gets into like, I mean, we're, you know, we're at a conference and they, they're doing something a little, like, there are conference talks at this conference, but there's also like. sort of less defined activities that aren't a conference talk. And I think that could be a reaction to some of this too. It's like I could watch a conference talk on, on video. How different is that going to be than being there in person? maybe it's not that different. Maybe, maybe I don't need to like travel across the country to go. Do something that I could see on video. So there's gotta be something here that, that, that meets that need that I can't meet any other way. So it's all these different, like, I would like to think that's how it is, right? All this media all is a part to play and it's all going to kind of continue and thrive and it's not going to be like, Oh, remember books? Like maybe, but hopefully not. Hopefully it's like, like what you're saying. Like it's all kind of serving different purposes that all kind of work together. Yeah. [00:44:43] Jeremy: I hope that's the case, because, um, I don't want to have to scroll through too many videos. [00:44:48] David: Yeah. The video's not for me. Large Language Models [00:44:50] Jeremy: I, I like, I actually do find it helpful, like, like I said, for the high level thing, or just to see someone's thought process, but it's like, if you want to know a thing, and you have a short amount of time, maybe not the best, um, of course, now you have all the large language model stuff where you like, you feed the video in like, Hey, tell, tell, tell me, uh, what this video is about and give me the code snippets and all that stuff. I don't know how well it works, but it seems [00:45:14] David: It's gotta get better. Cause you go to a support site and they're like, here's how to fix your problem, and it's a video. And I'm like, can you just tell me? But I'd never thought about asking the AI to just look at the video and tell me. So yeah, it's not bad. [00:45:25] Jeremy: I think, that's probably where we're going. So it's, uh, it's a little weird to think about, but, [00:45:29] David: yeah, yeah. I was just updating, uh, you know, like I said, I try to keep the book updated when new versions of Rails come out, so I'm getting ready to update it for Rails 7. 1 and in Amazon's, Kindle Direct Publishing as their sort of backend for where you, you know, publish like a Kindle book and stuff, and so they added a new question, was AI used in the production of this thing or not? And if you answer yes, they want you to say how much, And I don't know what they're gonna do with that exactly, but I thought it was pretty interesting, cause I would be very disappointed to pay 50 for a book that the AI wrote, right? So it's good that they're asking that? Yeah. [00:46:02] Jeremy: I think the problem Amazon is facing is where people wholesale have the AI write the book, and the person either doesn't review it at all, or maybe looks at a little, a little bit. And, I mean, the, the large language model stuff is very impressive, but If you have it generate a technical book for you, it's not going to be good. [00:46:22] David: yeah. And I guess, cause cause like Amazon, I mean, think about like Amazon scale, like they're not looking at the book at all. Like I, I can go click a button and have my book available and no person's going to look at it. they might scan it or something maybe with looking for bad words. I don't know, but there's no curation process there. So I could, yeah. I could see where they could have that, that kind of problem. And like you as the, as the buyer, you don't necessarily, if you want to book on something really esoteric, there are a lot of topics I wish there was a book on that there isn't. And as someone generally want to put it on Amazon, I could see a lot of people buying it, not realizing what they're getting and feeling ripped off when it was not good. [00:47:00] Jeremy: Yeah, I mean, I, I don't know, if it's an issue with the, the technical stuff. It probably is. But I, I know they've definitely had problems where, fiction, they have people just generating hundreds, thousands of books, submitting them all, just flooding it. [00:47:13] David: Seeing what happens. [00:47:14] Jeremy: And, um, I think that's probably... That's probably the main reason why they ask you, cause they want you to say like, uh, yeah, you said it wasn't. And so now we can remove your book. [00:47:24] David: right. Right. Yeah. Yeah. [00:47:26] Jeremy: I mean, it's, it's not quite the same, but it's similar to, I don't know what Stack Overflow's policy is now, but, when the large language model stuff started getting big, they had a lot of people answering the questions that were just. Pasting the question into the model [00:47:41] David: Which because they got it from [00:47:42] Jeremy: and then [00:47:43] David: The Got model got it from Stack Overflow. [00:47:45] Jeremy: and then pasting the answer into Stack Overflow and the person is not checking it. Right. So it's like, could be right, could not be right. Um, cause, cause to me, it's like, if, if you generate it, if you generate the answer and the answer is right, and you checked it, I'm okay with that. [00:48:00] David: Yeah. Yeah. [00:48:01] Jeremy: but if you're just like, I, I need some karma, so I'm gonna, I'm gonna answer these questions with, with this bot, I mean, then maybe [00:48:08] David: I could have done that. You're not adding anything. Yeah, yeah. [00:48:11] Jeremy: it's gonna be a weird, weird world, I think. [00:48:12] David: Yeah, no kidding. No kidding. [00:48:15] Jeremy: that's a, a good place to end it on, but is there anything else you want to mention, [00:48:19] David: No, I think we covered it all just yeah, you could find me online. I'm Davetron5000 on Ruby. social Mastodon, I occasionally post on Twitter, but not that much anymore. So Mastodon's a place to go. [00:48:31] Jeremy: David, thank you so much [00:48:32] David: All right. Well, thanks for having me.

In A Synthesis of Time: Zakat, Islamic Micro-finance and the Question of the Future in 21st-Century Indonesia (Palgrave Macmillan, 2020), Konstantinos Retsikas has anthropological investigation into the different forms the economy assumes, and the different purposes it serves, when conceived from the perspective of Islamic micro-finance as a field of everyday practice. The book is based on long-term ethnographic research in Java, Indonesia, with Islamic foundations active in managing zakat and other charitable funds, for purposes of poverty alleviation. Specifically, the book explores the social foundations of contemporary Islamic practices that strive to encompass the economic within an expanded domain of divine worship and elucidates the effects such encompassment has on time, its fissure and synthesis.  In order to elaborate on the question of time, the book looks beyond anthropology and Islamic studies, engaging attentively, critically and productively with the post-structuralist work of G. Deleuze, M. Foucault and J. Derrida, three of the most important figures of the temporal turn in contemporary continental philosophy. Through doing so, the book impressively untangles the complex relationship between Islamic economics, divine worship, and time. Konstantinos Retsikas is Reader in the Department of Anthropology and Sociology at SOAS, University of London, UK. His work focuses on temporality and personhood, and he has written extensively on issues of embodiment, place making, violence, and religion. He is also the author of Becoming: An Anthropological Approach to Understandings of the Person in Java (2012). Yadong Li is a PhD student in anthropology at Tulane University. He conducts ethnography among ufologists in China. His research interests lie at the intersection of the anthropology of the paranormal, hope studies, and post-structural philosophy.

This week on Elixir Wizards, Connor Rigby, Software Engineer at SmartRent, and Taylor Barto, Lead Embedded Software Engineer at Eaton, join Sundi Myint to compare notes on embedded systems development with Elixir, C, C++, and Java. They discuss using Elixir and the Nerves framework for firmware projects versus more traditional choices like C. The guests ask one another questions and gain valuable insights into challenges, tooling, resources, and more across different embedded ecosystems. In this episode, the guests expand their perspectives and demystify the concept of embedded systems for engineers outside the field. This cross-language exchange of ideas and experiences inspires continued learning and collaboration between embedded software engineers using different programming languages. Topics Discussed: Defining "true embedded": using an operating system vs. bare metal programming Benefits and drawbacks of Elixir, C, C++, and Java for firmware Many embedded systems today use Java as the programming language via Java Native Interface (JNI) to interface with C/C++ code How Elixir expands the toolbox available for firmware projects Testing, tooling, workflows, and debugging across languages Elixir/Nerves features like hot code reloading and testing vs. Java alternatives Learning curves for new languages and frameworks Industry trends around established vs emerging tools Applying functional programming principles like immutability in new domains Scaling firmware updates across large connected networks Continued maturation of Nerves may bring Elixir into consideration for roles where Java is commonly used today Hardening systems for reliability in safety-critical uses Debugging differences between web development and embedded Hiring considerations for niche languages Additional skills needed for embedded engineers, such as technical writing, reading schematics, and writing test instructions Resources and recommendations for getting started with embedded systems Links Mentioned: Nerves: https://github.com/nerves-project/nerves https://nerves-project.org/ AtomVM: https://github.com/atomvm/AtomVM GRiSP: https://github.com/grisp RISC-V: https://github.com/ultraembedded/riscv https://smartrent.com/ https://www.eaton.com/us/en-us.html Zig Programming Language: https://github.com/ziglang Docker: https://github.com/docker Build a Weather Station with Elixir and Nerves (https://pragprog.com/titles/passweather/build-a-weather-station-with-elixir-and-nerves/) by Alexander Koutmos, Bruce A.

Summary Aaron Meyers discusses the geolocated energy information platform for electric utility customer outages, covering 140 million utility customers, representing 93% of the US population. The talk explores the platform's evolution, trade-off analysis, and the adoption of an open-source solution with Docker, Java, Python, and GeoServer. The development includes creating a unique data set for visualizing outages consistently and analyzing utility behaviors within and across counties. The speaker highlights the release of a historic outage data archive, spanning November 2014 to December 2022, supporting open science and addressing energy justice questions. Highlights

Aaron Myers, the group lead at GE Informatics Engineering Group, discusses the EAGLE ITM Open Source Utility Outage Data Collect and Analysis platform in this presentation. EAGLE Eye is the Department of Energy's operational platform for situational awareness of utility outages, covering about 93% of the US and territories. The platform transitioned from commercial off-the-shelf to open source, employing Docker, Java, Spring Boot, and Apache Airflow for scalability. The data collection process involves scraping 450 utility outage maps every 15 minutes, and the platform aims to enhance data collection efficiency using Apache Airflow. Highlights

This week the boys join Mel Gibson and Sigourney weaver as they head to Indonesia with Peter Weir's “The Year of Living Dangerously”. Of course, the real standout is Linda Hunt in an Oscar winning (and history making) performance as Billy. This fantastic movie is about western print journalism in the age of eastern political chaos (sound familiar???????), and it stands out in the year 1982. Also listen in to hear John's mini review of David Fincher's “The Killer” starring Michael Fassbender, now on Netflix, and Dave's minuscule review of “The Marvels”, which is Marvel's lowest grossing (and one of the lowest rated) opening to date despite fantastic audience reviews.  Find all of our Socials at: https://linktr.ee/theloveofcinema.

Your host is Tobias Macey and today I'm interviewing Eran Yahav about building an AI powered developer assistant at Tabnine Interview Introduction How did you get involved in machine learning? Can you describe what Tabnine is and the story behind it? What are the individual and organizational motivations for using AI to generate code? What are the real-world limitations of generative AI for creating software? (e.g. size/complexity of the outputs, naming conventions, etc.) What are the elements of skepticism/oversight that developers need to exercise while using a system like Tabnine? What are some of the primary ways that developers interact with Tabnine during their development workflow? Are there any particular styles of software for which an AI is more appropriate/capable? (e.g. webapps vs. data pipelines vs. exploratory analysis, etc.) For natural languages there is a strong bias toward English in the current generation of LLMs. How does that translate into computer languages? (e.g. Python, Java, C++, etc.) Can you describe the structure and implementation of Tabnine? Do you rely primarily on a single core model, or do you have multiple models with subspecialization? How have the design and goals of the product changed since you first started working on it? What are the biggest challenges in building a custom LLM for code? What are the opportunities for specialization of the model architecture given the highly structured nature of the problem domain? For users of Tabnine, how do you assess/monitor the accuracy of recommendations? What are the feedback and reinforcement mechanisms for the model(s)? What are the most interesting, innovative, or unexpected ways that you have seen Tabnine's LLM powered coding assistant used? What are the most interesting, unexpected, or challenging lessons that you have learned while working on AI assisted development at Tabnine? When is an AI developer assistant the wrong choice? What do you have planned for the future of Tabnine?

In this episode, Conor and Bryce conclude their conversation with Jonathan O'Connor and chat about a plethora of topics: multiparadigm languages, Ratfor, airport lounges, Meeting C++, code::dive and more.Link to Episode 155 on WebsiteDiscuss this episode, leave a comment, or ask a question (on GitHub)TwitterADSP: The PodcastConor HoekstraBryce Adelstein LelbachAbout the Guest:Jonathan O'Connor in 1988 joined Glockenspiel, a small Irish company. C++ had no virtual destructors, but it did have a coroutine library! I spent 2 years teaching C++ and OOP. In 2000, he switched over to Java. But by 2010, he started 7 wonderful years writing in Ruby. In 2016, he returned to a completely different C++, where one never had to see a pointer if you didn't want to. These days he is helping to make the world a better place writing C++ code for LADE GmbH, a company building electric car charging infrastructure.Show NotesDate Recorded: 2023-10-18Date Released: 2023-11-10Jonathan O'Connor Meeting C++ BioRatforSoftware Tools by Brian Kernighan and P.J.
