Stephanie shares her newfound interest in naming conventions, highlighting a resource called "Classnames" that provides valuable names for programming and design. Joël, in turn, talks about using AI to generate names for D&D characters, emphasizing how AI can help provide inspiration and reasoning behind name suggestions. Then, they shift to Joël's interest in Roman history, where he discusses a blog by a Roman historian that explores distinctions between state and non-state peoples in the ancient Mediterranean. Together, the hosts delve into the importance of asking questions as consultants and developers to understand workflows, question assumptions, and build trust for better onboarding. Stephanie categorizes questions by engagement stages and their social and technical aspects, while Joël highlights how questioning reveals implicit assumptions and speeds up learning. They stress maintaining a curious mindset, using questions during PR reviews, and working with junior developers to foster collaboration. They conclude with advice on documenting answers and using questions for continuous improvement and effective decision-making in development teams.

I'm Joël Quenneville. STEPHANIE: And I'm Stephanie Minn. And together, we're here to share a bit of what we've learned along the way. JOËL: So, Stephanie, what's new in your world? STEPHANIE: So, if it has not been clear about just kind of the things I'm mentioning on the podcast the past few weeks, I've been obsessed with naming things lately [chuckles] and just thinking about how to name things, and, yeah, just really excited about...or even just having fun with that more than I used to be as a dev. And I found a really cool resource called "Classnames." Well, it's like just a little website that a designer and developer shared from kind of as an offshoot from his personal website. I'll link it in the show notes. But it's basically just a list of common names that are very useful for programming or even design. It's just to help you find some inspiration when you're stuck trying to find a name for something. And they're general or abstract enough that, you know, it's almost like kind of like a design pattern but a naming pattern [laughs], I suppose. JOËL: Ooh. STEPHANIE: Yeah, right? And so, there's different categories. Like, here's a bunch of words that kind of describe collections. So, if you need to find the name for a containment or a group of things, here's a bunch of kind of words in the English language that might be inspiring. And then, there's also other categories like music for describing kind of the pace or arrangement of things. Fashion, words from fashion can describe, like, the size of things. You know, we talk about T-shirt sizes when we are estimating work. And yeah, I thought it was really cool that there's both things that draw on, you know, domains that most people know in real life, and then also things that are a little more abstract. But yeah, "Classnames" by Paul Robert Lloyd — that's been a fun little resource for me lately. JOËL: Very cool. Have you ever played around at all with using AI to help you come up with the naming? STEPHANIE: I have not. But I know that you and other people in my world have been enjoying using AI for inspiration when they feel a little bit stuck on something and kind of asking like, "Oh, like, how could I name something that is, like, a group of things?" or, you know, a prompt like that. I suspect that that would also be very helpful. JOËL: I've been having fun using that to help me come up with good names for D&D characters, and sometimes they're a little bit on the nose. But if I sort of describe my character, and what's their vibe, and a little bit of, like, what they do and their background, and, like, I've built this whole, like, persona, and then, I just ask the AI, "Hey, what might be some good names for this?" And the AI will give me a bunch of names along with some reasoning for why they think that would be a good match. So, it might be like, oh, you know, the person's name is, I don't know, Starfighter because it evokes their connection to the night sky or whatever because that was a thing that I put in the background. And so, it's really interesting. And sometimes they're, like, just a little too obvious. Like, you don't want, you know, Joe Fighter because he's a fighter. STEPHANIE: And his name is Joe [laughs]. JOËL: Yeah, but some of them are pretty good. STEPHANIE: Cool. Joël, what's new in your world? JOËL: I guess in this episode of how often does Joël think about the Roman Empire... STEPHANIE: Oh my gosh [laughs]. JOËL: Yes [laughs]. STEPHANIE: Spoiler: it's every day [laughs]. JOËL: Whaaat? There's a blog that I enjoy reading from a Roman historian. It's called "A Collection of Unmitigated Pedantry", acoup.blog. He's recently been doing an article series on not the Romans, but rather some of these different societies that are around them, and talking a little bit about a distinction that he calls sort of non-state peoples versus states in the ancient Mediterranean. And what exactly is that distinction? Why does it matter? And those are terms I've heard thrown around, but I've never really, like, understood them. And so, he's, like, digging into a thing that I've had a question about for a while that I've been really appreciating. STEPHANIE: Can you give, like, the reader's digest for me? JOËL: For him, it's about who has the ability to wield violence legitimately. In a state, sort of the state has a monopoly on violence. Whereas in non-state organizations, oftentimes, it's much more personal, so you might have very different sort of nobles or big men who are able to raise, let's say, private armies and wage private war on each other, and that's not seen as, like, some, like, big breakdown of society. It's a legitimate use of force. It's just accepted that that's how society runs. As opposed to in a state, if a, you know, wealthy person decided to raise a private army, that would be seen as a big problem, and the state would either try to put you down or, like, more generally, society would, like, see you as having sort of crossed a line you shouldn't have crossed. STEPHANIE: Hmm, cool. I've been reading a lot of medieval fantasy lately, so this is kind of tickling my brain in that way when I think about, like, what drives different characters to do things, and kind of what the consequences of those things are. JOËL: Right. I think it would be really fascinating to sort of project this framework forwards and look at the European medieval period through that lens. It seems to me that, at least from a basic understanding, that the sort of feudal system seems to be very much in that sort of non-state category. So, I'd be really interested to see sort of a deeper analysis of that. And, you know, maybe he'll do an addendum to this series. Right now, he's mostly looking at the Gauls, the Celtiberians, and the Germanic tribes during the period of the Roman Republic. STEPHANIE: Cool. Okay. Well, I also await the day when you somehow figure how this relates to software [laughter] and inevitably make some mind-blowing connection and do a talk about it [laughs]. JOËL: I mean, theming is always fun. There's a talk that I saw years ago at Strange Loop that was looking at the defense policy of the Roman Emperor Diocletian and the Roman Emperor Constantine, and the ways that they sort of defended the borders of the empire and how they're very different, and then related it to how you might handle network security. STEPHANIE: Whaat? JOËL: And sort of like a, hey, are we using more of a Diocletian approach here, or are we using more of a Constantine approach here? And all of a sudden, just, like, having those labels to put on there and those stories that went with it made, like, what could be a really, like, dry security talk into something that I still remember 10 years later. STEPHANIE: Yeah. Yeah. We love stories. They're memorable. JOËL: So, I'll make sure to link that in the show notes. STEPHANIE: Very cool. JOËL: We've been talking a lot recently about my personal note system, where I keep a bunch of, like, small atomic notes that are all usually based around a single thesis statement. And I was going through that recently, and I found one that was kind of a little bit juicy. So, the thesis is that consultants are professional question-askers. And I'm curious, as a consultant yourself, how do you feel about that idea? STEPHANIE: Well, my first thought would be, how do I get paid to only ask in questions [laughs] or how to communicate in questions and not do anything else [laughs]? It's almost like I'm sure that there is some, like, fantasy character, you know, where it's like, there's some villain or just obstacle where you have this monster character who only talks in questions. And it's like a riddle that you have to solve [laughs] in order to get past. JOËL: I think it's called a three-year-old. STEPHANIE: Wow. Okay. Maybe a three-year-old can do my job then [laughter]. But I do think it's a juicy one, and it's very...I can't wait to hear how you got there, but I think my reaction is yes, like, I do be asking questions [laughs] when I join a project on a client team. And I was trying to separate, like, what kinds of questions I ask. And I kind of came away with a few different categories depending on, like, the stage of the engagement I'm in. But, you know, when I first join a team and when I'm first starting out consulting for a team, I feel like I just ask a lot of basic questions. Like, "Where's the Jira board [laughs]?" Like, "How do you do deployments here?" Like, "What kind of Git process do you use?" So, I don't know if those are necessarily the interesting ones. But I think one thing that has been nice is being a consultant has kind of stripped the fear of asking those questions because, I don't know, these are just things I need to know to do my work. And, like, I'm not as worried about, like, looking dumb or anything like that [laughs]. JOËL: Yeah. I think there's often a fear that asking questions might make you look incompetent or maybe will sort of undermine your appearance of knowing what you're talking about, and I think I've found that to be sort of the opposite. Asking a lot of questions can build more trust, both because it forces people to think about things that maybe they didn't think about, bring to light sort of implicit assumptions that everyone has, and also because it helps you to ramp up much more quickly and to be productive in a way that people really appreciate. STEPHANIE: Yeah. And I also think that putting those things in, like, a public and, like, documented space helps people in the future too, right? At least I am a power Slack searcher [laughs]. And whenever I am onboarding somewhere, one of the first places I go is just to search in Slack and see if someone has asked this question before. I think the next kind of category of question that I discerned was just, like, questions to understand how the team understands things. So, it's purely just to, like, absorb kind of like perspective or, like, a worldview this team has about their codebase, or their work, or whatever. So, I think those questions manifest as just like, "Oh, like, you know, I am curious, like, what do you think about how healthy your codebase is? Or what kinds of bugs is your team, like, dealing with?" Just trying to get a better understanding of like, what are the challenges that this team is facing in their own words, especially before I even start to form my own opinions. Well, okay, to be honest, I probably am forming my own opinions, like, on the side [laughs], but I really try hard to not let that be the driver of how I'm showing up and especially in the first month I'm starting on a new team. JOËL: Would you say these sorts of questions are more around sort of social organization or, like, how a team approaches work, that sort of thing? Or do you classify more technical questions in this category? So, like, "Hey, tell me a little bit about your philosophy around testing." Or we talked in a recent episode "What value do you feel you get out of testing?" as a question to ask before even, like, digging into the implementation. STEPHANIE: Yeah, I think these questions, for me, sit at, like, the intersection of both social organization and technical questions because, you know, asking something like, "What's the value of testing for your team?" That will probably give me information about how their test suite is like, right? Like, what kinds of tests they are writing and kind of the quality of them maybe. And it also tells me about, yeah, like, maybe the reasons why, like, they only have just unit tests or maybe, like, just [inaudible 12:31] test, or whatever. And I think all of that is helpful information. And then, that's actually a really...I like the distinction you made because I feel like then the last category of questions that I'll mention, for now, feels like more geared towards technical, especially the questions I ask to debunk assumptions that might be held by the team. And I feel like that's like kind of the last...the evolution of my question-asking. Because I have, hopefully, like, really absorbed, like, why, you know, people think the way they do about some of these, you know, about their code and start to poke a little bit on being like, "Why do you think, you know, like, this problem space has to be modeled this way?" And that has served me well as a consultant because, you know, once you've been at an organization for a while, like, you start to take a lot of things for granted about just having to always be this way, you know, it's like, things just are the way they are. And part of the power of, you know, being this kind of, like, external observer is starting to kind of just like, yeah, be able to question that. And, you know, at the end of day, like, we choose not to change something, but I think it's very powerful to be able to at least, like, open up that conversation. JOËL: Right. And sometimes you open up that conversation, and what you get is a link to a big PR discussion or a Wiki or something where that discussion has already been had. And then, that's good for you and probably good for anybody else who has that question as well. STEPHANIE: I'm curious, for you, though, like, this thesis statement, atomic note, did you have notes around it, or was it just, like, you dropped it in there [laughs]? JOËL: So, I have a few things, one is that when you come in as a consultant, and, you know, we're talking here about consultants because that's what we do. I think this is probably true for most people onboarding, especially for non-junior roles where you're coming in, and there's an assumption of expertise, but you need to onboard onto a project. This is just particularly relevant for us as consultants because we do this every six months instead of, you know, a senior developer who's doing this maybe every two to three years. So, the note that I have here is that when you're brought on, clients they expect expertise in a technology, something like Ruby on Rails or, you know, just the web environment in general. They don't expect you as a consultant to be an expert in their domain or their practices. And so, when you really engage with this sort of areas that are new by asking a lot of questions, that's the thing that's really valuable, especially if those questions are coming from a place of experience in other similar things. So, maybe asking some questions around testing strategies because you've seen three or four other ways that work or don't work or that have different trade-offs. Even asking about, "Hey, I see we went down a particular path, technically. Can you walk me through what were the trade-offs that we evaluated and why we decided this was the path that was valuable for us?" That's something that people really appreciate from outside experts. Because it shows that you've got experience in those trade-offs, that you've thought the deeper thoughts beyond just shipping the next ticket. And sometimes they've made the decisions without actually thinking through the trade-offs. And so, that can be an opening for a conversation of like, "Hey, well, we just went down this path because we saw a blog article that recommended this, or we just did this because it felt right. Talk us through the trade-offs." And now maybe you have a conversation on, "Hey, here are the trade-offs that you're doing. Let me know if this sounds right for your organization. If not, maybe you want to consider changing some things or tweaking your approach." And I think that is valuable sort of at the big level where you're thinking about how the team is structured, how different parts of work is done, the technical architecture, but it also is valuable at the small level as well. STEPHANIE: Yeah, 100%. There is a blog post I really like by Hazel Weakly, and it's called "The Power of Being New: A Proven Recipe for High Impact." And one thing that she says at the beginning that I really enjoy is that even though, like, whenever you start on a new team there's always that little bit of pressure of starting to deliver immediate value, right? But there's something really special about that period where no one expects you to do anything, like, super useful immediately [laughs]. And I feel like it is both a fleeting time and, you know, I'm excited to continue this conversation of, like, how to keep integrating that even after you're no longer new. But I like to use that time to just identify, while I have nothing really on my plate, like, things that might have just been overlooked or just people have gotten used to that sometimes is, honestly, like, can be a quick fix, right? Like, just, I don't know, deleting a piece of dead code that you're seeing is no longer used but just gets fallen off other people's plates. I really enjoy those first few weeks, and people are almost, like, always so appreciative, right? They're like, "Oh my gosh, I have been meaning to do that." Or like, "Great find." And these are things that, like I said, just get overlooked when you are, yeah, kind of busy with other things that now are your responsibility. JOËL: You're talking about, like, that feeling of can you add value in the, like, initial time that you join. And I think that sometimes it can be easy to think that, oh, the only value you can add is by, like, shipping code. I think that being sort of noisy and asking a lot of questions in Slack is often a great way to add value, especially at first. STEPHANIE: Yeah, agreed. JOËL: Ideally, I think you come in, and you don't sort of slide in under the radar as, like, a new person on the team. Like, you come in, and everybody knows you're there because you are, like, spamming the channel with questions on all sorts of things and getting people to either link you to resources they have or explaining different topics, especially anything domain-related. You know, you're coming in with an outside expertise in a technology. You are a complete new person at the business and the problem domain. And so, that's an area where you need to ask a lot of questions and ramp up quickly. STEPHANIE: Yes. I have a kind of side topic. I guess it's not a side topic. It's about asking questions, so it's relevant [laughs]. But one thing that I'm curious about is how do you approach kind of doing this in a place where question asking is not normalized and maybe other people are less comfortable with kind of people asking questions openly and in public? Like, how do you set yourself up to be able to ask questions in a way that doesn't lead to just, like, some just, like, suspicion or discomfort about, like, why you're asking those questions? JOËL: I think that's the beauty of the consultant title. When an organization brings in outside experts, they kind of expect you to ask questions. Or maybe it's not an explicit expectation, but when they see you asking a lot of questions, it sort of, I think, validates a lot of things that they expect about what an outside expert should be. So, asking a lot of questions of trying to understand your business, asking a lot of questions to try to understand the technical architecture, asking questions around, like, some subtle edge cases or trade-offs that were made in the technical architecture. These are all things that help clients feel like they're getting value for the money from an outside expert because that's what you want an outside expert to do is to help you question some of your assumptions, to be able to leverage their, like, general expertise in a technology by applying it to your specific situation. I've had situations where I'll ask, like, a very nuanced, deep technical question about, like, "Hey, so there's, like, this one weird edge case that I think could potentially happen. How do we, like, think through about this?" And one of the, like, more senior people on the team who built the initial codebase responded, like, almost, like, proud that I've discovered this, like, weird edge case, and being like, "Oh yeah, that was a thing that we did think about, and here's why. And it's really cool that, like, day one you're, like, just while reading through the code and were like, 'Oh, this thing,' because it took us, like, a month of thinking about it before we stumbled across that." So, it was a weird kind of fun interaction where as a new person rolling on, one of the more experienced devs in the codebase almost felt, like, proud of me for having found that. STEPHANIE: I like that, yeah. I feel like a lot of the time...it's like, it's so easy to ask questions to help people feel seen, to be like, "Oh yeah, like, I noticed this." And, you know, if you withhold any kind of, like, judgment about it when you ask the question, people are so willing to be like, yeah, like you said, like, "Oh, I'm glad you saw that." Or like, "Isn't that weird? Like, I was feeling, you know, I saw that, too." Or, like, it opens it up, I think, for building trust, which, again, like, I don't even think this is something that you necessarily need to be new to even do. But if at any point you feel like, you know, maybe your working relationship with someone could be better, right? To the point where you feel like you're, like, really on the same page, yeah, ask questions [laughs]. It can be that easy. JOËL: And I think what can be really nice is, in an environment where question asking is not normalized, coming in and doing that can help sort of provide a little bit of cover to other people who are feeling less comfortable or less safe doing that. So, maybe there's a lot of junior members on the team who are feeling not super confident in themselves and are afraid that asking questions might undermine their position in the company. But me coming in as a sort of senior consultant and asking a lot of those questions can then help normalize that as a thing because then they can look and say, "Oh, well he's asking all these questions. Maybe I can ask my question, and it'll be okay." STEPHANIE: I also wanted to talk about setting yourself up and asking questions to get a good answer, asking good questions to get useful answers. One thing that has worked really well for me in the past few months has been sharing why I'm asking the question. And I think this goes back to a little bit of what I was hinting at earlier. If the culture is not really used to people asking questions and that just being a thing that is normal, sharing a bit of intention can help, like, ease maybe some nervousness that people might feel. Especially as consultants, we also are in a bit of a, I don't know, like, there is some power dynamics occasionally where it's like, oh, like, the consultants are here. Like, what are they going to come in and change or, like, start, you know, doing to, quote, unquote, "improve", whatever, I don't know [laughs]. JOËL: Right, right. STEPHANIE: Yeah, that's the consultant archetype, I think. Anyway. JOËL: Just coming in and being like, "Oh, this is bad, and this is bad, and you're doing it wrong." STEPHANIE: [laughs] JOËL: Ooh, I would be ashamed if I was the author of this code. STEPHANIE: Yeah, my hot take is that that is a bad consultant [laughs]. But maybe I'll say, like, "I am looking for some examples of this pattern. Where can I find them [laughs]?" Or "I've noticed that the team is struggling with, like, this particular part of the codebase, and I am thinking about improving it. What are some of your biggest challenges, like, working with this, like, model?" something like that. And I think this also goes back to, like, proving value, right? Even if it's like, sometimes I know kind of what I want to do, and I'll try to be explicit about that. But even before I have, like, a clear action item, I might just say like, "I'm thinking about this," you know, to convey that, you know, I'm still in that information gathering stage, but the result of that will be useful to help me with whatever kind of comes out of it. JOËL: A lot of it is about, like, genuine curiosity and an amount of empathetic listening. Existing team knows a lot about both the code and the business. And as a consultant coming on or maybe even a more senior person onboarding onto a team, the existing team has so much that they can give you to help you be better at your job. STEPHANIE: I was also revisiting a really great blog post from Julia Evans about "How to Ask Good Questions." And this one is more geared towards asking technical questions that have, like, kind of a maybe more straightforward answer. But she included a few other strategies that I liked a lot. And, frankly, I feel like I want to be even better at finding the right time to ask questions [laughs] and finding the right person to ask those questions to. I definitely get in the habit of just kind of like, I don't know, I'll just put it out there and [laughs], hopefully, get some answers. But there are definitely ways, I think, that you can be more strategic, right? About identifying who might be the best person to provide the answers you're looking for. And I think another thing that I often have to balance in the consulting position is when to know when to, like, stop kind of asking the really big questions because we just don't have time [laughs]. JOËL: Right. You don't want to be asking questions in a way that's sort of undermining the product, or the decisions that are being made, or the work that has to get done. Ideally, the questions that you're asking are helping move the project forward in a positive way. Nobody likes the, you know, just asking kind of person. That person's annoying. STEPHANIE: Do you have an approach or any thoughts about like, once you get an answer, like, what do you do with that? Yeah, what happens then for you? JOËL: I guess there's a lot of different ways it can go. A potential way if it's just, like, an answer explained in Slack, is maybe saying, "We should document this." Or maybe even like, "Is this documented anywhere? If not, can I add that documentation somewhere?" And maybe that's, you know, a code comment that we want to add. Maybe that's an entry to the Wiki. Maybe that's updating the README. Maybe that's adding a test case. But converting that into something actionable can often be a really good follow-up. STEPHANIE: Yeah, I think that mitigates the just asking [laughs] thing that you were saying earlier, where it's like, you know, the goal isn't to ask questions to then make more work for other people, right? It's to ask questions so, hopefully, you're able to take that information and do something valuable with it. JOËL: Right. Sometimes it can be a sort of setup for follow-up questions. You get some information and you're like, okay, so, it looks like we do have a pattern for interacting with third-party APIs, but we're not using it consistently. Tell me a little bit about why that is. Is that a new pattern that we've introduced and we're trying to, like, get more buy-in from the team? Is this a pattern that we used to have, and we found out we didn't like it? So, we stopped using it, but we haven't found a replacement pattern that we like. And so, now we're just kind of...it's a free-for-all, and we're trying to figure it out. Maybe there's two competing patterns, and there is this, like, weird politics within the tech team where they're sort of using one or the other, and that's something I'm going to have to be careful to navigate. So, asking some of those follow-up questions and once you have a technical answer can yield a lot of really interesting information and then help you think about how you can be impactful on the organization. STEPHANIE: And that sounds like advice that's just true, you know, regardless of your role or how long you've been in it, don't you think? JOËL: I would say yes. If you've been in the role a long time, though, you're the person who has that sort of institutional history in your mind. You know that in 2022, we switched over from one framework to another. You know that we used to have this, like, very opinionated architect who mandated a particular pattern, and then we moved away from it. You know that we were all in on this big feature last summer that we released and then nobody used it, and then the business pivoted, but there's still aspects of it that are left around. Those are things that someone knew onboarding doesn't know and that, hopefully, they're asking questions that you can then answer. STEPHANIE: Have you been in the position where you have all that, like, institutional knowledge? And then, like, how do you maintain that sense of curiosity or just that sense of kind of, like, what you're talking about, that superpower that you get when you're new of being able to just, you know, kind of question why things are the way they are? JOËL: It's hard, right? We're talking about how do you keep that sort of almost like a beginner's mindset, in this case, maybe less of a, like, new coder mindset and more of a new hire mindset. It's something that I think is much more front of mind for me because I rotate onto new clients every, like, 6 to 12 months. And so, I don't have very long to get comfortable before I'm immediately thrown into, like, a new situation. But something that I like to do is to never sort of solely be in one role or the other, a sort of, like, experienced person helping others or the new person asking for help. Likely, you are not going to be the newest person on the team for long. Maybe you came on as a cohort and you've got a group of new people, all of whom are asking different questions. And maybe somebody is asking a question that you've asked before, that you've asked in a different channel or on a call with someone. Or maybe someone joins two weeks after you; you don't have deep institutional knowledge. But if you've been asking a lot of questions, you've been building a lot of that for yourself, and you have a little bit that you can share to the next person who knows even less than you do. And that's an approach that I took even as an apprentice developer. When I was, like, brand new to Rails and I was doing an internship, and another intern joined me a couple of weeks after, and I was like, "You know what? I barely know anything. But I know what an instance variable is. And I can help you write a controller action. Let's pair on that. We'll figure it out. And, you know, ask me another question next week. I might have more answers for you." So, I guess a little bit of paying it forward. STEPHANIE: Yeah, I really like that advice, though, of, like, switching up the role or, like, kind of what you're working on, just finding opportunities to practice that, you know, even if you have been somewhere for a long time. I think that is really interesting advice. And it's hard, too, right? Because that requires, like, doing something new, and doing something new can be hard [laughs]. But if you're, you know, aren't in a consultant role, where you're not rotating onto new projects every 6 to 12 months, that, I feel like, would be a good strategy to grow in that particular way. JOËL: And even if you're not switching companies or in a consulting situation, it's not uncommon to have people switch from one team to another within an organization. And new team might mean new dynamics. That team might be doing a slightly different approach to project management. Their part of the code might be structured slightly differently. They might be dealing with a part of the business domain that you're less familiar with. While that might not be entirely new to you because, you know, you know a little bit of the organization's DNA and you understand the organization's mission and their core product, there are definitely a lot of things that will be new to you, and asking those questions becomes important. STEPHANIE: I also have another kind of, I don't know, it's not even a strategy. It's just a funny thing that I do where, like, my memory is so poor that, like, even code I wrote, you know, a month ago, I'm like, oh, what was past Stephanie thinking here [laughs]? You know, questioning myself a little bit, right? And being willing to do that and recognizing that, like, I have information now that I didn't have in the past. And, like, can that be useful somehow? You know, it's like, the code I wrote a month ago is not set in stone. And I think that's one way I almost, like, practice that skill with myself [laughs]. And yeah, it has helped me combat that, like, things are the way they are mentality, which, generally, I think is a very big blocker [laughs] when it comes to software development, but that's a topic for another day [laughs]. JOËL: I like the idea of questioning yourself, and I think that's something that is a really valuable skill for all developers. I think it can come up in things like documentation. Let's say you're leaving a comment on a method, especially one that's a bit weird, being able to answer that "Why was this weird technical decision made?" Or maybe you do this in your PR description, or your commit message, or in any of the other places where you do this, not just sort of shipping the code as is, but trying to look at it from an outsider's eyes. And being like, what are the areas where they're going to, like, get a quizzical look and be like, "Why is this happening? Why did you make this choice?" Bonus points if you talked a little bit about the trade-offs that were decided on to say, "Hey, there were two different implementations available for this. I chose to take implementation A because I like this set of trade-offs better." That's gold. And, I guess, as a reviewer, if I'm seeing that in a PR, that's going to make my job a lot easier. STEPHANIE: Yes. Yeah, I never thought about it that way, but yeah, I guess I do kind of apply, you know, the things that I would kind of ask to other team members to myself sometimes. And that is...it's cool to hear that you really appreciate that because I always kind of just did it for myself [laughs], but yeah, I'm sure that it, like, is helpful for other people as well. JOËL: I guess you were asking what are ways that you can ask questions even when you are more established. And talking about these sorts of self-reflective questions in the context of review got me thinking that PRs are a great place to ask questions. They're great when you're a newcomer. One of the things I like to do when I'm new on a project is do a lot of PR reviews so I can just see the weird things that people are working on and ask a lot of questions about the patterns. STEPHANIE: Yep. Same here. JOËL: Do a lot of code reading. But that's a thing that you can keep doing and asking a lot of questions on PRs and not in a, like, trying to undermine what the person is doing, but, like, genuine questions, I think, is a great way to maintain that mindset. STEPHANIE: Yeah, yeah, agreed. And I think when I've seen it done well, it's like, you get to be engaged and involved with the rest of your team, right? And you kind of have a bit of an idea about what people are working on. But you're also kind of entrusting them with ownership of that work. Like, you don't need to be totally in the weeds and know exactly how every method works. But, you know, you can be curious about like, "Oh, like, what were you thinking about this?" Or like, "What about this pattern appeals to you?" And all of that information, I think, helps you become a better, like, especially a senior developer, but also just, like, a leader on the team, I think. JOËL: Yeah, especially the questions around like, "Oh, walk me through some of the trade-offs that you chose for this method." And, you know, for maybe a person who's more senior, that's great. They have an opportunity to, like, talk about the decisions they made and why. That's really useful information. For a more junior person, maybe they've never thought about it. They're like, "Oh, wait, there are trade-offs here?" and now that's a great learning opportunity for them. And you don't want to come at it from a place of judgment of like, oh, well, clearly, you know, you're a terrible developer because you didn't think about the performance implications of this method. But if you come at it from a place of, like, genuine curiosity and sort of assuming the best of people on the team and being willing to work alongside them, help them discover some new concepts...maybe they've never, like, interacted so much with performance trade-offs, and now you get to have a conversation. And they've learned a thing, and everybody wins. STEPHANIE: Yeah. And also, I think seeing people ask questions that way helps more junior folks also learn when to ask those kinds of questions, even if they don't know the answer, right? But maybe they start kind of pattern matching. Like, oh, like, there might be some other trade-offs to consider with this kind of code, but I don't know what they are yet. But now I know to at least start asking and find someone who can help me determine that. And when I've seen that, that has been always, like, just so cool because it's upskilling happening [laughs] in practice. JOËL: Exactly. I love that phrase that you said: "Asking questions where you don't know the answers," which I think is the opposite of what lawyers are taught to do. I think lawyers the mantra they have is you never ask a witness a question that you don't know the answer to. But I like to flip that for developers. Ask a lot of questions on PRs where you don't know the answer, and you'll grow, and the author will grow. And this is true across experience levels. STEPHANIE: That's one of my favorite parts about being a developer, and maybe that's why I will never be a lawyer [laughter]. JOËL: On that note, I have a question maybe I do know the answer to.

Plumbum is “ a small yet feature-rich library for shell script-like programs in Python.

JOËL: Hello and welcome to another episode of The Bike Shed, a weekly podcast from your friends at thoughtbot about developing great software. I'm Joël Quenneville. STEPHANIE: And I'm Stephanie Minn. And together, we're here to share a bit of what we've learned along the way. JOËL: So, Stephanie, what's new in your world? STEPHANIE: So I got a very exciting package in the mail the other day that I wanted to share with you. So I think I've mentioned her on the pod before, but I got a package of software development-related zines by Julia Evans, and I'm going to share a few of the titles that I got. So I picked up, "Oh shit, git!" [laughs] Can I swear on this podcast? I don't know. I guess we're going to find out. Or maybe we can just make the executive decision that it's fine. [laughs] I also got "Hell Yes! CSS!", "The Pocket Guide to Debugging," which I think I mentioned previously. I had seen the PDF version before, but now I have this cute, little, I don't know, six-inch book that I can carry around for all of my debugging needs. Who knows? Maybe I'll be out in the world and just need to pull it out [laughs] and debug something while I'm on the train; who's to say? And then I also picked up "HTTP: Learn Your Browser's Language!" So I'm really excited to have these little illustrated digest-sized resources. I think they'll look really cute on my shelf next to my more intense hardcore technical books like "Design Patterns" and "Practical Object-Oriented Design in Ruby" or whatever. I'm really excited about the more creative endeavors people have done with creating educational resources about software development. In fact, I think last time when we talked about creativity and creative expression, we totally missed the world of side projects. And I've really just enjoyed when people illustrate things and make stuff a lot more accessible to a wider audience than a traditional textbook or more text-based heavy resources. JOËL: I love when people go for a bit more of the playful or quirky when dealing with technical topics. And this is a great example. I love Julia Evans' work. But I'm also reminded of things like "Why's (poignant) Guide to Ruby," "Learn You a Haskell for Great Good!" or even...I forget the title of it. But there's a book by...I think it's Jamis Buck on mazes. And it's told in this sort of quirky style in a narrative. But it's all about maze-solving algorithms but told through the eyes of characters who are wandering through a maze, and it's just delightful. STEPHANIE: Aww, that's so cute. I love that. I also just had the thought that these things would make great gifts for a fledgling developer or a developer in your life who, if you don't want to get them something super specialized or technical or whatever. There are so many, like you said, quirky and fun things out there that I'm sure they'll appreciate. So, Joël, what's new in your world? JOËL: I play D&D regularly with some colleagues at thoughtbot. And recently, I got to thinking about the mechanics of rolling dice. Specifically, what dice can be rolled together? Like, can I roll multiple dice at the same time? And which one do you have to wait for the outcome of a previous roll before it makes sense to roll it? That was really interesting to me because I think that connects to a lot of other things that we do in software, where sometimes some things are independent. You can do them at the same time. And then, other times, you have to wait for the outcome of the first thing before you can even start doing the second thing. So I think, in many ways, it's a great metaphor for the difference between parallel versus series operations. STEPHANIE: I think it's very funny that you found a way to connect D&D to software development. I'm just imagining you rolling your die and then while you're doing that, having some revelation like the math lady meme or whatever, just thinking about, whoa, if this outcome happens, then [laughs] what happens? I have not joined in on our company's D&D campaign, but I do like that y'all post little updates about the story in a public space for the whole company to check out. So sometimes I've been searching for some message in our company's knowledge base, and I have stumbled upon a post about the campaign so far and what happened in last night's session, you know, how all the adventurers fought the big bird, [laughs] and it is very delightful to me. JOËL: It's a really fun way, I think to be creative. I think I enjoy the role-playing side of it a little bit more than just the mechanics of rolling dice, even though the thing I was excited to share today is rolling dice is fun. It is kind of like doing improv, where you're trying to figure out what would your character do and how do they respond to what other people say? It's fun, but it's hard. STEPHANIE: One burning question I have is, does anyone do voices for their characters? JOËL: Absolutely. Aji Slater, who was on a previous episode of this podcast, is part of this campaign, and their character has some really fun voices. STEPHANIE: That's awesome. I'm really interested in joining as a guest or something. But yeah, the improv aspect of it kind of freaks me out. I bet it's a really welcoming group. And if other people are getting into it, then I can get into it too. JOËL: Yeah, this group is very, very low-key. Most people playing, I think, are fairly new to the game. So it's very friendly, very kind of tolerant of, oh, you didn't know this rule existed, that's totally fine. We'll make it work, things like that. STEPHANIE: Nice. So another recent development in my world is that I started a new client project, actually the same client that you've been working on for many months, Joël. JOËL: Yes, the same client but different teams within the client. So we don't get to necessarily interact with each other day to day. But it is interesting that now we get to share knowledge about how this application works with each other. STEPHANIE: Yeah, yeah. And I don't think we've gotten a chance to work together even in the same world like this before. So that's kind of exciting. JOËL: How has the onboarding been for you? STEPHANIE: So, one onboarding development that was surprisingly easy and felt good was setting up a new laptop. So the client company shipped a laptop to me to use for all of their work. And I had to set up just the laptop from scratch, so I could develop on it. And I was able to do that pretty painlessly with the help of the dotfiles that I had previously put together and all of the configurations that I had exported and uploaded to like a cloud drive. And so I was able to have that up and running within a day with all of my favorite keyboard shortcuts, applications, all my little preferences, and that felt really good. So I'm going to pat myself on the back [laughs] for past Stephanie's efforts in making current Stephanie's life easier. JOËL: I'm curious, do you use thoughtbot's dotfiles as the base for your development environment, or do you use something custom? STEPHANIE: I have my own personal dotfiles that I have in a GitHub repo. But I think I did, at one point, go through thoughtbot's dotfiles for inspiration. I found that it has just a lot of extra stuff that I don't really need, but I do like that it's out there. So if any folks want a place to start with having a laptop setup configuration, you should definitely check that out. And we can link that in the show notes. JOËL: I really like the tool rcm, which is also by thoughtbot that allows you to have a modular system of dotfiles that you can pull from a few different sources and combine together. STEPHANIE: Oh, that's neat. I hadn't known about that one. That's cool. JOËL: It's a suite of command-line tools that allows you to pull probably from a git repo. And it might be several, and then trying to pull them all to the right place on your machine to be executable. So, in my case, I have the thoughtbot dotfiles and then also some personal ones. And it just kind of merges them together based on some rules and creates all the dotfiles in my home directory for that. STEPHANIE: Nice. I think the one thing that I do need to keep up on is pushing updates to the dotfiles when I make changes locally because I did have to pull in a few things that I had adjusted or made tweaks to that didn't make it to the source that I was pulling from on this new machine. This is actually my fifth MacBook that I own [laughs] just from remnants of jobs and clients' past. And one day...I keep telling myself that I'll have to return one of the older ones that I'm not using anymore, but as of now, I am an owner of five computers. [laughs] JOËL: Just start mining Bitcoin on the idle ones. STEPHANIE: Oh. [laughs] That's genius. I guess that's definitely a better use than them just sitting in my drawers. JOËL: I guess you're paying for power, and that's kind of the whole point, so... STEPHANIE: That's fair. JOËL: What are some things that you like to do when you onboard onto a new project? STEPHANIE: So, aside from my laptop adventures, when I joined this new project, I had a few things in mind that I wanted to achieve during this onboarding process. One of the things I think I want to get better at is understanding the business when I'm onboarding onto a new client. I think this is an area that previously I hadn't really focused on, but I'm now understanding is actually really important to being set up for success on a team. And so, as consultants, we're dropped into a client project oftentimes when things are already moving. And they kind of clearly have some things that they were hoping we could help with. But I am hoping to also use this time to just take a bit of a step back and ask questions about, like, what is the product? And what are its core features? And who are its users? And also, what's the direction of the business? Can I get some more context on how things are right now? We're so frequently brought in and being like, okay, like, you're going to work on this project but without the context of is the business scaling right now, or what are its struggles? We aren't quite able to make as informed decisions as we could if we had been at the company for longer and had just seen things change and had more of a feel of why we're doing what we're doing. JOËL: I love that you're asking all those questions upfront. I feel like coming in onto a new project, and that can be as a consultant, or it could be just starting a new job, is the perfect time to just be asking all of those questions. And people, I think, appreciate when we ask those questions. Sometimes I think as consultants; we can sometimes be afraid that, oh, if we're asking these sorts of basic questions, people might think less of us. But I think the opposite happens where because we're asking those foundational questions about the business model, about the future of the product, about how the technical architecture works, people really appreciate that we're asking those foundational questions where other people might not. So it actually helps build credibility rather than hurting credibility. STEPHANIE: Yeah, and I think they are really important in making the right technical decision, too, because it can help inform where you spend your time refactoring or evaluating whether this shortcut is worth it to meet this deadline or if it's not because of the bigger picture and where things are headed. If anything, I've learned that being a developer really isn't just about being in the code but having as much information as possible so that there is less ambiguity and you have more clarity to make the right choices when you do have to write the code. Another key aspect that I have become a lot more observational about, I think, is understanding the team that I'm joining, especially what their process is, how they communicate. One thing that's kind of funny about seeing a lot of different companies and how they work as consultants is they might claim to use agile, but in reality, it is a little bit different than that. And you can have that perspective as an outsider. Things like pointing an estimation is kind of all over the place in the industry. So I really like to make sure I fully understand how the team does that and what points means to them. I think another thing that I want to do during my onboarding time this week and as I'm getting to know developers on the client side is learning about the pain points that they're feeling. And, yeah, just getting more of a feel about what's top of mind for them and where is a good space to invest my time and my energy. Lastly, some more basic stuff is communication. Another thing about being a contractor that's challenging is that we don't normally get the full onboarding experience that full-time hires do. And so we may or may not have an onboarding mentor or a buddy and finding out, okay, who is the right person that I should be asking questions to? Or where's the right space for that? When you join new teams, are there any other things that you like to take into consideration? JOËL: I like that you talked about understanding the team's process. One thing that I often like to do pretty early on is make some kind of small code change but then have it go through the full process of coding on my machine to deploy it in production. And so just find some small change in the code that needs to be done, and maybe it's an easy bug fix or something. But just so I can walk through all the steps and find out what the team's process is. What are some sort of weird things that this team does that other people might not that I need to know about? Where does review happen? Is there a staging environment, unexpected ways which my change might get rejected? Things like that. So walking through the entire, I guess you could say software development lifecycle, kind of speedrunning is, I think, a really valuable exercise to do really early on a new project. STEPHANIE: Yeah, that's a great point. Like I mentioned, I think that looks so different for every team. And I'm now learning about new tools and SaaS products that I have never seen before. And even though I have an understanding of the software development lifecycle in general, just learning those quirks is very valuable so that you can be a contributor as soon as possible. JOËL: I like to contribute on day one, if possible, so kind of in order of...I don't want to say order of priority. But the order of things that I often do on a new project is one, clone the repo, try to run the setup script, or manually step through instructions in the README. Depending on the repo, that might be 10 minutes. That might be all of my first day. Number two, try to run the test suite. STEPHANIE: Yes. JOËL: Number three is figure out what went wrong for me in step one or two, make a fix for it, commit it, and open up a PR for it, and that's my contribution. If I can do those three things on day one, I feel like that is a solid first day. STEPHANIE: That's great. I love that. What can you do to help improve this process and make it just a little bit better for someone else? I think another good first-day task might be automating a part of that process that is currently manual and kind of annoying. MID-ROLL AD: Debugging errors can be a developer's worst nightmare...but it doesn't have to be. Airbrake is an award-winning error monitoring, performance, and deployment tracking tool created by developers for developers that can actually help cut your debugging time in half.

STEPHANIE: So once you've cloned the repo and you're poking around the codebase, what are some things that you notice when you're looking at the code? JOËL: Ooh, that's always fun. In a Rails application, there are a few files I almost always open first in a new project just to get a feel for it. Number one is the routes file. What does that look like? Is it huge? Is it small? Are there a lot of non-standard routes in there, not just standard RESTful resources? That's going to tell me a lot about how things are structured. I can probably even get a sense of what controllers are large, what controllers have 20 non-RESTful actions in them just by looking at the routing file. The other place I like to look at is the user model. Generally, that just collects so many methods. And so I can also often get a feel about the app just by looking at that. And then from there, it's pulling on connections and trying to say, okay, well, what seems to be the core model of this app that everything coalesces around? And maybe for an e-commerce app, it's some kind of product, or maybe for an insurance product, it might be some kind of policy object. And so you find that, and then you find all of the core business logic around there. And that can often give you a really good picture of what the app is like. STEPHANIE: Yeah, a few other things I would add to that list of things to check out is the Gemfile. I like to look at that to see what gems are familiar to me. Do they have authentication, common authentication gems that I've used before? Or is there a lot of stuff that's new to me? And it also kind of tells you, are they more likely to reach for a library or try to build something themselves? I liked that you mentioned that you try to run the test suite early on. I think test coverage is a good place to investigate as well if they have any metrics, you know, that also tells you that it is or isn't something they value. And then seeing like, okay, what parts are well-tested and what parts are a little less tested? I'm really glad that you pointed out how much information you can glean about controllers because then, once you're poking around in there, that can tell you a lot about where are the scary parts of the app? I've found that to be really interesting. You know, sometimes you can just open up a file and be like, whoa, [laughs] and have kind of a gut reaction. Other times, you might pick it up from other developers, and you might start hearing about areas of the app that they are a little nervous to touch. JOËL: I definitely connect with that. I feel like many products have a particular file that is kind of scary and that people don't want to touch. And sometimes, people will tell you upfront, sometimes, you just discover it yourself. And I've been on projects where it's like, oh no, we have a ticket that's come up. It's fairly straightforward, except we know whoever picks it up is going to have to touch the scary file, and I'm not it. STEPHANIE: Yeah, absolutely. JOËL: I'm curious if you run any kind of automated tooling to try to understand a little bit more about the code. So I'm thinking things like maybe Flog or Flay or some of those tools to get a feel for maybe what are the hotspots in the application, anything like that that you like to look for? STEPHANIE: That's a great point. I think the only times I have invested energy into doing that has been more when I'm doing a code audit for a client, which, in some cases, is a separate service that clients can pay consultants for. But I can see the value of doing it when you're joining a team for the first time. JOËL: In a sense, I almost feel like we do a kind of abbreviated code audit for ourselves as part of onboarding. STEPHANIE: That's fair. I wonder if you can use those tools and scope it in a way to the particular team or areas in the codebase that you know that you'll be working on. JOËL: You mentioned the Gemfile earlier. And one thing that maybe seems super obvious is checking version numbers for things like Rails and Ruby because that will significantly impact how development is going to work. Is this a Rails 3 app, or is this a Rails 7 application? STEPHANIE: Yeah, yeah, that's a great point. I am glad you mentioned that because I think that's probably the very first thing [laughs] that I would do just to set my expectations around what I'm working with. JOËL: I feel like it's one of those things that's often just told to you when somebody helps you onboard. It's like, "Okay, you can clone the repo. It's over here. By the way, this is a Rails 3 app. We're kind of behind the times. Here are some weird things we've had to do to keep it alive. We have this other team. They're in this back room over there, slowly working on a Rails 4 upgrade. It's been in progress for four months, but we think we're pretty close. Can't wait for Rails 4." STEPHANIE: Oh God. [laughs] I think the alternative is a developer being like, "Oh yeah, we just upgraded to Rails 7," and they're all really excited and feeling really good about it, [laughs] as they should be, because I think that Rails upgrades are an important thing to stay on top of. And it is really great when you are working on a project that gets to be up to date there. JOËL: Yeah, Rails upgrades are interesting because I feel like when you're proactive about them, they're not that bad, especially more modern versions. I think Rails has gotten a lot better about making those upgrades smoother today than they were ten years ago. But when you're not up to date about them, when you've just kind of procrastinated on doing the updates, every month or year that you wait to do the update makes it so much harder to do that update when the time comes. Because now more gems have fallen out of date, more things have now been abandoned that you just can't use. A lot of community knowledge is just not around as much anymore. Because Rails 3...I forget when Rails 4 came out, probably about ten years ago. So people who remember how things were done idiomatically ten years ago, some of that knowledge has kind of passed on. It's not as prevalent as knowledge around Rails 6 or Rails 7 is. STEPHANIE: 100%. I think I heard someone at thoughtbot identify themselves as a post-Rails 5 generation developer. And I loved that because it really tells you a lot about just their experience. And it's kind of fun. I can imagine some kind of BuzzFeed quiz or something that's like, what Rails generation are you? But yeah, I've certainly seen pro-con lists about joining different projects, and a con might be the app is still on Rails 3. And then, if the app is on a very new version of Rails, that's usually in the pro column because folks are excited about getting to have all that good, new stuff. What do you look out for in terms of design patterns in a codebase? Is that something that kind of sets off your radar at all? JOËL: One thing that will definitely make me raise an eyebrow is heavy use of metaprogramming. I've been bitten by that a lot on projects. Some things are way too clever by half. So a lot of metaprogramming typically means it's going to be difficult to read and follow the flow of logic in the code. And also, there might be some unexpected bugs. Or I found once a memory leak that happened because of some weird metaprogramming. So that definitely makes me a little bit skeptical of part of the code. STEPHANIE: Yeah, that's fair. And it also just makes it hard to understand the domain when you have no idea where things go. And you have to just find out later when you are debugging and are in the middle of desperately trying to figure out how this app works. So I can see how that is a little suspicious. I think one thing that I am reevaluating for myself when I notice design patterns is trying to figure out, do I want to perpetuate them? Do I want to follow them? And in the past, I have been more likely to just follow an existing pattern in the codebase. But one thing that I'm hoping to do moving forward is to simply ask, how do decisions get made around patterns? Who gets to introduce them? Are they documented? What does that process look like? Do you have a conversation with the team about it? Just so that I have more tools in my toolbox, I think if I ever do find something that I feel really strongly about, that should be different than what I'm seeing in the codebase. So kind of expanding my skill set there. JOËL: I think that's a fantastic question to ask, and I've done this on previous projects. And sometimes, the answers are just absolutely illuminating. So you see a weird pattern, and you ask, like, "Oh, where does that come from? Why do we do that?" And some will say," Oh yeah, that was Bob back in, you know, 2017. He read an article and was really a fan of this thing, and he put it everywhere. Nobody else really understood the pattern, but we haven't really been able to change it. And he's no longer with the company, and now we just kind of...it's there." Or sometimes it's like, "Oh, great question because you see, we have this subtle business problem. And we've got to reconcile these two pieces of technology with also this expectation that our customers have. And so we came across this pattern, and we decided to use it." And it's these things where just looking at the code with no context, you're like, that's weird. Why would you want to do that? And then, when you understand the underlying problem, it makes so much sense. It's like, okay, I don't love this pattern, but it's the correct solution here, and I fully support having that here. It's a tricky problem at the intersection of technological problems and business problems, and this was the best way we could solve it. I'm not always super happy, but it is the right choice. STEPHANIE: Yeah, I've heard someone describe that as code archaeology in a way that all codebases have a story to tell about how they got to the current state that they're in. And I have certainly struggled with this but trying to approach joining a new team and working on a new codebase, especially if it's legacy code, from a place of curiosity rather than being combative about it. And just going through the git commits or just simply asking members of the team, like, "Hey, what's going on here?" and getting to hear some of those fun stories. JOËL: Yeah, most code exists for a reason. It's not just people writing things just because, particularly code that, you walk in as an outsider and think, oh, that's bad code or looks weird. It's usually for a reason. People aren't just purposefully writing this to trigger you two years down the road. It's also important...as a new person onboarding onto a project, people care about your perspective. As an outsider, oftentimes, it's really rich to bring in an outside perspective. But it's also not a great look to come in and just immediately be like, "Oh, we need to tear this thing down," or "This is so bad." It's important to build trust with the team. And as with so many things in life, seek to understand before running your mouth. STEPHANIE: Wow, how insightful, Joël. [laughs] Speaking of building trust, can we talk a little bit about different strategies we have for doing that? JOËL: Yeah. As a new person on the team, you really want to build a strong connection with the client and to build that trust because then you can be more effective in doing your job. You can bring more value to the client. What are some ways that you like to get that moving in a positive direction early on a new project? STEPHANIE: I think setting up channels of communication is really important, so, ideally, having a one-on-one with a manager or a team lead because that is a great place to make sure that the work you're doing is aligned with what they think you should be doing. So figuring out what their expectations are, like, what do you expect me to get done in my first week? And then what do you want me to be doing by the first month? That is important because we might think about all the things we would love to improve about this codebase or like influence on the team. But if that is not lined up with their views of what success looks like, then we're not quite delivering on the value that we [laughs] had hoped that we would. Another thing that I'm starting to notice a lot more, and we talked a little bit about this previously when we talked about the value of sustainability in web development, but learning what the team's values are and also what the organization's values are because that will really inform the behavior of folks on the team and the decisions that they make. So some values that come to mind are transparency, or collaboration, or growth, or speed. Like, if you find out those underlying foundational pillars, that can really help you orient yourself in your work and being like, okay, I know that this organization really focuses on these kinds of things, so I would like to try to make decisions that uphold or are in line with the things that are important to them. JOËL: I want to really second your comment about good communication. That is one of the most powerful things you can do to build credibility to build trust with another human being, and that can happen in a lot of ways. Like you're saying, some of it is setting up actual communication channels with a manager. Some of that can be the things we mentioned earlier, like asking questions about the architecture, trying to learn all about the product and the business. That can also be being active in that particular team's Slack channel. Sometimes new people come on to a team, and they're a little bit more timid, and they're just kind of not present. And so kind of coming in and...like, you don't want to take over the channel but being active in the channel, asking your questions in that channel, even just talking about your onboarding experience being like, "Hey, I'm running through...I got stuck on this thing. Here's the thing I did to get unstuck." People love seeing that. And it helps them to feel like you're actively participating from day one. STEPHANIE: Yes, that is a great transition to what I wanted to make sure to say at the end of this is that your onboarding experience matters. I know that when you're joining a new team, you might feel a lot of pressure to start contributing and make sure that you are providing value. But your onboarding experience should be inclusive, and you should advocate for your needs. Like, if you don't have access to credentials or there are just various blockers to your onboarding, that's a big deal, and it should not be a gatekeep-y process. Everyone wants you to be able to do your job, and so if you're running into those issues, it's definitely important to raise those concerns for yourself and also for anyone else who comes along the way. Also, everything is new, and will probably feel uncomfortable. If you're anything like me, I feel a lot of pressure to prove myself when I join a new team and start contributing left and right. But it's just important to remember that when all this stuff is new, feeling uncertain or feeling confused and just being in that beginner's mindset again can be uncomfortable, but that is totally normal. JOËL: I feel like something I sometimes do that ties all of these ideas together is when I'm encountering some new code or a new problem, to help myself understand it, I will diagram it. But oftentimes, it can be nice to share that diagram in the team's Slack channel and to say, "Hey, I'm new to the project, and I was exploring this area, and I kind of diagrammed it." Just talk a little bit about the thing that you're doing and maybe what you learned about it. People love that. Visuals are a really powerful tool. And you might be surprised that there might be some team members that have been on the project for a while who never really understood that part of the code. And so they will latch on to what you've shared and be like, "Oh, thank you, because now I finally have a feel for that part." Or maybe you didn't get it quite right, and somebody will follow up and say, "Hey, I love your diagram, but you have a misconception here. There's actually a different piece that connects here." And then you can have a conversation, and you just revealed a blind spot. And so I've found that that can be a really positive way to get started. STEPHANIE: Yeah, absolutely. Joël Quenneville, professional diagrammer. But even if you don't draw a diagram, putting your assumptions out into the world and how you understand things I think is really valuable because, yeah, it's like you are showing your learning path and also being open to receiving feedback if it's not quite right and, hopefully, spreading knowledge all around. So I love that. JOËL: This reminds me a little bit of the episode we had with Steve Polito about learning in public. And he was focused more on learning about Rails, and open source, and things like that. But there's a sense in which you can sort of learn the product or learn the codebase. And public means your team channel. So you can say, "Hey, I'm digging into this model, and here's how I understand the way things work. It's a bulleted list of three things." You might get some good comments on that. You might get other people who appreciate it. So kind of learning the internals of a product within the public confines of a team, I think, is a really good framework as well. STEPHANIE: Absolutely. JOËL: On that note, Shall we wrap up?

Stephanie shares that she's been taking an intro to basket weaving class at a local art studio, and it's an interesting connection to computer science. Joël eats honeycomb live on air and shares a video that former Bike Shed host Steph Viccari found from Ian Anderson. It's a parody to the tune of "All I Want For Christmas Is You," but it's all about the Ruby 3.2 release. In this episode, Stephanie and Joël shift away from literature and lean into art. Writing code is technical work, but in many ways, it's also aesthetic work. It's a work of art. How do you feel about expressing yourself creatively through your code?

JOËL: Hello and welcome to another episode of The Bike Shed, a weekly podcast from your friends at thoughtbot about developing great software. I'm Joël Quenneville. STEPHANIE: And I'm Stephanie Minn. And together, we're here to share a bit of what we've learned along the way. JOËL: So, Stephanie, what's new in your world? STEPHANIE: I'm really excited to share that I've been taking this intro to weaving class at a local art studio. I'm actually a few weeks in, and it's wrapping up soon. But one thing that I found really cool at the very first class was that the instructor mentioned that weaving was, in some ways, a predecessor or inspiration to modern computing. And he said that, and I got really excited because surely that meant that I would be good at this thing [laughs] and this craft, and then I promptly kind of forgot about it. But I was inspired the other night to look up this history to just learn more about weaving and its connection to computer science. And I learned that, in particular, the invention of something called the Jacquard loom really led to early computing machines because, basically, weaving involves threading horizontal and vertical fibers. And the way you do it if you thread the horizontal fiber, also called the weft, over or under the vertical fibers, called the warp, you get different patterns. And so with the Jacquard loom, this invention utilized punch cards as instructions for basically binary code, and that would tell the loom how to raise and lower those vertical threads, which would then lead to a beautiful pattern. And after that invention, this previously very laborious process became automated. And that also had a really big impact on the textile industry. And fabric became a lot more available at a much lower cost. So that was a really cool little history lesson for me. JOËL: That is really cool. So are you saying that punch cards, as we know them from early computing, were borrowed as a concept from the weaving industry? STEPHANIE: Yeah, that's at least what I've read. I can see now how complex weaving tapestries and patterns set the stage for more complex computations. And I don't know if I'm going to keep going down this weaving journey. I liked the intro class because it was very chill, and I got to use my hands. And I had a little bit of fun making, I don't know, like ten by 12-inch little tapestry. But yeah, I've definitely seen other more advanced weavers make really beautiful textiles and fiber arts. And it's really cool to see the application of that detail-oriented skill in different formats. JOËL: Are you going to try to make your own punch cards? STEPHANIE: That's an interesting evolution of this skill [laughs] for sure. I think what I really did like was the hands-on approach. And so the punch cards did make this process automated. But I personally enjoyed the switching of the threads and pulling them through and doing it with my hands instead of something that's kind of turned into automated machine work. Does that inspire you in some way? JOËL: I think sometimes it's interesting, right? As software people, we sort of have the two urges. We work in so much automation. When we see a process, we would love to try to automate it ourselves, even if it's been done before. So, oh, could I build a small, automatic mechanical loom using punch cards? That sounds like a fun automation challenge. At the same time, so much of my daily job is automation that sometimes it's nice to kind of remove automation entirely from the picture and, like you said, just work with your hands. STEPHANIE: That's a really interesting way to think about it. I do believe that people have different reactions to it, like you said, where they're like, "Wow, I can use my skills to do this really cool thing." On the other hand, you might also respond with, "Wow, I've done this automation code-writing work for eight hours. So now I really want to do something completely different." And I think that's the camp that I was in, at least when I first signed up for this class, just having space, like three hours a week, to sit and not look at a computer and deal with the physical realm. JOËL: So here's the other route that I think a lot of software people take, and that is, here's a fun mechanical process that can be automated. What if we simulated it virtually? So what if I create a program where you can sort of create your own punch card, like, decide where you want to punch the holes? And maybe these are just radio buttons or something or checkboxes in a grid on a webpage. And then, the program will output an SVG that is the thing that would have been woven if you'd used it in that pattern. And so now you can kind of play around with, like, huh, what if I punch here? What if I unpunch here? And you get all these patterns out, and you could just get to try it around. STEPHANIE: That's fascinating. I can't believe your brain went there. [laughter] But yeah, the idea that it's not actually about the pattern itself but the holes that you make, that part being the creative process and then what comes out of it then being a bit of a surprise or just something organic that's a really interesting take too. JOËL: Something that I find is really fun about software and things created from software is this sort of really short feedback loop in terms of trial and error. So if you were actually having a weaving machine and you made a physical punch card, and then you try something, and you realize it's not quite right, the machine weaved something you didn't quite like, now you've got to set it up again. You probably have to start from scratch with a new punch card because you can't really unpunch holes unless maybe you can put tape over it or something. That trial-and-error feedback loop is much shorter. Whereas with a program, you just pause the simulation, punch-unpunch some holes, restart, and then you just kind of keep trying. And there's something fun about that creative exploration when you've got that really tight feedback loop. STEPHANIE: That's fair. I think perhaps that actually might be why doing it manually, and by it, I mean weaving, gives you a little bit more room to [laughs] debug if you will, because you can see when something goes wrong. And this actually happened to me in class earlier this week where I didn't thread the fiber over instead of under. And I was like, oh, this doesn't look right. Like, that's not the look I'm going for. And then I could kind of quickly see, oh, I missed a thread over here and unravel and do it again. Whereas what you just described, if the punch card is wrong and then you create this big piece of fabric, at that point, I'm not really sure what happens then. If someone out there is a weaving expert and knows the answer; I would be very curious to know. JOËL: Now I kind of wish we'd had this conversation last month because, in early January, there was a game jam event that happened. It's a yearly or biyearly Historically Accurate Game Jam, and they select a theme, and then everybody has to submit a game, or a simulation, or something, an interactive program that fits with the theme. And this year's theme was the Industrial Revolution. And I feel like simulating an old automated loom with punch cards would be the perfect fit for something that's small enough that I could build it in a week without spending 10 hours a day working on it. It fits within the theme, and it's still kind of fun. STEPHANIE: Wow, that would have been a really great idea. If there was an award for best fitting the theme, I think that would have won because then you're also tackling the history of computing. I was talking about earlier the loom obviously being...or the automated loom also really playing a big role in the Industrial Revolution. And, I don't know, maybe this is our future club, Joël, and we're going to get into video game development. [laughs] What's new in your world, Joël? JOËL: There are two things. One is that today former Bike Shed host, Stephanie Viccari, shared a video with me from Ian Anderson. This was made last December to the tune of All I Want For Christmas Is You. But it's all about the, at that time, upcoming Ruby 3.2 release. It is amazing. The lyrics talk about the different features that are upcoming. It rhymes. It's set to meter. I am just blown away by this. And I'm just really hyped [laughs] about this video. STEPHANIE: You sent it to me and I gave it a watch before we sat down to record, and I also loved this video. It was so fun. And I think Ruby has a bit of a tradition of releasing new versions around Christmas time. So if this became a tradition, that would be very fun, and maybe instead of singing Christmas carols, we'll be singing new Ruby version carols around the holidays. JOËL: I feel like if Ian wants to do another one next Christmas, now that you have the precedent, it'd be a great space to try something to the tune of Last Christmas because now you can reference back last year's song. STEPHANIE: Yeah. I might as well just go all in and create a whole Christmas album of Ruby anticipation carols. [laughter] JOËL: Yeah, really excited about that. Kudos to Ian. And for all of our listeners, we'll link the video on the show notes of the podcast. Go and check it out; it is worth the two and a half-minutes of your life. STEPHANIE: Agreed. JOËL: The other cool thing, for the past few episodes, we've been talking a lot about hexagons and how they show up in nature, and bees, and how they build their honeycombs and whether that is sort of by design or sort of just happens by nature through sort of external forces. And so this week, I went out to the store, and I bought some real honeycomb. And I'm going to try it on air. STEPHANIE: [laughs] Oh my gosh, I didn't realize that's what was happening. [laughter] Okay, I'm ready. JOËL: All right, I'm going to take a slice. STEPHANIE: Wow. For research. JOËL: For science. STEPHANIE: Wow, that is a big bite. [laughs] JOËL: Hmmm, it's basically crunchy honey. STEPHANIE: So I've enjoyed honeycomb in that raw form on ice cream. I really like it on there and oatmeal and stuff like that. I think it's a little bit waxy. Like, once you get to chewing the bits at the end, that part is a bit of a less pleasant mouth-feel [laughs] in my opinion. What are you experiencing right now? JOËL: Yeah, so like you're saying, the honey kind of dissolves away in your mouth. You had this really fun mix of textures. But then, in the end, you do end up with a ball of [laughter] beeswax in your mouth. STEPHANIE: Oh no. JOËL: Which I understand is completely safe to eat, so... STEPHANIE: Yeah, that's true. JOËL: I'm just going to eat the whole thing. STEPHANIE: I think it's kind of like swallowing gum. [laughs] JOËL: Which apparently does not last for seven years in your digestive system; that's a myth. STEPHANIE: Wow, debunking myths, trying honeycomb. You're welcome, to all The Bike Shed listeners out there. Investigating the important things. JOËL: What is interesting is that we're talking about the structural power of hexagons. I can cut a pretty thin slice of the comb, and it doesn't fall apart. It still has a lot of strength to it, which is nice because it means that the honey doesn't just go splashing everywhere. I can cut up a fairly thin slice, pick it up, it still holds the honey, put it in my mouth, and it doesn't make a mess. STEPHANIE: The bees know what they're doing. [laughs] Cool. Would you eat raw honeycomb again? JOËL: Well, I got a whole block, and I had one tiny slice. So, yes, I will be eating the rest of this. STEPHANIE: [laughs] JOËL: I don't think this will be a regular thing in my weekly groceries. But I would bring this out again for a special occasion. Or I can see this fitting nicely, like you said, on maybe certain breakfasts, even on a charcuterie board or something. STEPHANIE: Oh yeah, that's a really good use for it. JOËL: In some ways, it's nice because it's a way to have honey without having to have it on something else or having to eat it with a spoon. It's honey that comes with its own carrying vessel. STEPHANIE: That's great. Yeah, like a bread bowl for soup. [laughs] JOËL: Exactly. Bees make their own bread bowls for honey. STEPHANIE: [laughs] MID-ROLL AD: Debugging errors can be a developer's worst nightmare...but it doesn't have to be.

JOËL: So, for the last couple of weeks, we've been joking that this is turning into the Stephanie and Joël book club because we've been talking about a lot of articles and books. Today, I'd like to shift a little bit away from literature and lean into art. Writing code is a technical work, but in many ways, it's also an aesthetic work. It's a work of art. How do you feel about the idea of expressing yourself creatively through your code? STEPHANIE: So this is interesting to me because it's actually quite different from what we've been talking about in recent episodes around the idea of writing sustainable code, code for other people to read. Because if you are writing code purely for creative expression and just for yourself, that will look very different than what I think folks have kind of called boring technology, which is choosing the patterns, the tools, the frameworks that are tried and true, and just kind of sticking to the things that people have solved before. And so, in some ways, I don't know if I really get to express myself creatively in the code that I write, which I think is okay for me because I don't really consider myself someone who needs a creative outlet in my work. What about you? What thoughts do you have about this? JOËL: I think it's interesting the way you described it. I'm almost wondering if I'm making maybe a comparison to physical architecture; maybe you almost have a sort of brutalist perspective on the things you construct. STEPHANIE: [laughs] JOËL: So they're functional. They're minimal. They are not always the prettiest to look at, but they're solid. Does that metaphor sound about right to you? STEPHANIE: I feel like I have to make a pun about SOLID, the design patterns, and code. JOËL: Ooh. STEPHANIE: [laughs] But I think I like brutalist, I mean, the term itself. I don't know if I necessarily identify with it in terms of my work and output. But the idea that the code that I do is functional is, I think, particularly important to me as a developer. And I don't just mean, like, oh, the code works, so it's done, but functional for whatever need I'm solving and also for the people who are working with this code again in the future. I mentioned boring technology. There's a talk that I'm kind of referencing by Dan McKinley, and you can check out his slides at boringtechnology.club. And he talks about this idea of decision-making and how that relates to writing boring or creative code. And he also references Maslow's hierarchy of needs. And so, ideally, if you're working in an existing codebase, all the low-level decisions have been made for you. And then you can kind of traverse the hierarchy and focus your creativity on the high-level problems that you're trying to solve. So maybe you're not necessarily expressing your creativity in the syntax or whatever pattern you're using, again, because a lot of those things have been solved. But where the creativity comes from is the particular domain or business problem you have and the real-world constraints that you're faced with. And how do you figure out what to do given those constraints? JOËL: I think that lines up a lot with my own experience as well. I think as a newer developer, syntax is sort of the thing that's top of mind. And so, maybe trying to get clever with syntax is something that I would focus on more. Sometimes that's trying to get code really short and terse. Sometimes it's because I want to try. Can I do this thing with a particular piece of syntax, or even just does it look pretty? I think now, in my code, I am actually kind of boring with my syntax. I, probably when I write Ruby, mostly use a kind of slimmed-down set of syntax and don't use the full expressive power of the language for most of my day-to-day needs. So basic things with objects, and methods, and blocks, sort of the basic building blocks that we get from Ruby regular conditionals, if...else, and a few other nice things that the language gives us. But, in many ways, it almost feels like...I don't know if you've ever seen the simplified English Wikipedia. STEPHANIE: No, I haven't. What is that? JOËL: They're treating it, I think, like a separate language, but it is a version of Wikipedia in English with a more restricted vocabulary to try to make the content more accessible to those that might struggle with more standard English. So it's a sort of smaller subset of English. And, in many ways, I feel like a lot of the day-to-day Ruby code that I write is simplified, Ruby. STEPHANIE: Wow, that's really interesting. I think this also goes back to the specialized vocabulary episode we talked about. And is there value in keeping things accessible, and straightforward, and boring but at the cost of being able to express yourself with everything you have available to you? This is a bit of a tangent, I guess, but I grew up speaking Chinese with my parents, but since then, I have really lost a lot of that vocabulary. And, in some ways, I really struggle with communicating in Chinese because I feel like I'm not able to express myself exactly the way I want to in the way that I can in English. And when I'm talking to my parents, yeah, that's been a bit of a challenge for me because I do really value being able to say things the way that I mean, and I'm not able to have that with my limited vocabulary. So I can also see how people might not enjoy working within these confines of boring syntax and boring frameworks. JOËL: Sometimes it's nice to give yourself a sort of syntactical restriction, but they're very low-level when it comes to most of what we do for programming. And I think that's sort of what I've learned as my career has evolved is that programming is so much more than just learning syntax. So kind of like with art, maybe it's nice to restrict yourself to say, oh, can I do something with only a particular brushstroke technique, or restricting myself to a particular palette or a particular medium? And that can foster a lot of creativity. So, similarly, I think you could do some things like playing Code Golf, not on production code; please don't. STEPHANIE: [laughs] JOËL: But as an experiment in a side project or just almost as a piece of art, that can be a really interesting problem to solve and give you a deeper understanding of the language. And I'm sure there are plenty of other syntactical limitations you could put on yourself or maybe fancy things you would like to explore and say, "Well, this is over the top. We don't need to structure it in this way or use this syntax. But I want to sort of push the boundaries of what can be done with it. Let's see where I can take it." STEPHANIE: That's really fair. And I think it relates back to what I was saying earlier about perhaps creativity when writing software products comes from the constraints of the business of, in some ways, physical aspects of development. In the Dan McKinley talk, I mentioned about choosing boring technology. He generally recommends against bringing in a new language or framework because of the costs, the carrying cost of doing that, and the long-term maintenance to consider. But he instead suggests turning the question on its head and being like, how can we solve this problem with the current technology that we do have? And I think that relates to what you were saying about being able to push the boundaries of a particular medium or tool and in a way that you might not have considered before. JOËL: Exactly. And I think going back to the analogy with art; sometimes it is nice to restrict yourself to a particular brushstroke or something like that to try to foster creativity. But oftentimes, you want to explore creativity in much higher-level ways. So maybe you're not restricting things like brushstrokes and color, and, instead, you want to explore lighting. You want to explore maybe certain ways of mixing colors. There are all sorts of, I think, higher-level ways that you can be creative in art that's not just the mechanics of how you apply pigment to canvas. And we see the same thing like you were saying, in code where there's a lot of higher level business problems. Generally, how do we want to structure large chunks of the code? How do we want to build abstractions? Although that can also be a dangerous place to get too creative in. STEPHANIE: Yeah, absolutely. Do you consider yourself a creative person or need a creative outlet? And how does writing code or software development play a role in that for you? JOËL: I would say, yes, I consider myself a creative person. And I would consider coding, in general, to be a creative endeavor. I sometimes describe to people that writing code is like building something out of infinite legos. You're constrained only by the power of your imagination and the amount of time you're willing to put into constructing the thing that you're building. Of course, then you have all sorts of business constraints. And there are things you want to do on a work project that are probably not the same as what you would want to do on a client project or on a personal project. But there's still creativity, I think, at every level and sometimes even outside of the code itself. Just understanding and breaking down the business problem can require a ton of creativity before you even write a single line of code in your editor. I was reading a Twitter thread the other day by @GeePawHill that sort of proposes that there are sort of four steps in evolution of kind of the mindset that programmers go through over their career. And I'd be curious to hear your thoughts on this evolution if you kind of agree with it or disagree with it if that maybe lines up with some of your experience. So this Twitter thread proposes four levels of thinking that we go through. I think we can kind of jump between these levels at various points in our work. So we might do all of these in a day, but to a certain extent, they also follow a little bit of a progression in our career. So the first level is thinking in terms of syntax; that's just knowing the characters to type in the editor. The second level is thinking in terms of code, that's, thinking a little bit more semantically. So now, instead of thinking, oh, do I need if then curly brace, then closed curly brace? Now we're thinking more in terms of, okay, I need a branch in the flow of control for my logic here. And at that level, maybe you don't even need to think about the syntax quite so much because you're so comfortable with. It kind of just fades away. Building beyond that, now you're thinking in terms of your paradigm. So Ruby is an object-oriented language, so you might be thinking in terms of what objects do I need to represent this problem and how do they need to talk to each other? And the sort of underlying semantics of, oh, do I need a conditional here or not? Those might start fading away because now you're thinking at a slightly higher level. And then, finally, thinking in terms of change sets. Now you're thinking less in terms of the language itself and more in terms of the business problems and how the current behavior of the software is different and needs to change to get to where we want the behavior to be. STEPHANIE: I think I disagree a little bit with the idea that it's a progression. And I'm thinking about how when you have a beginner's mind, anything is possible. And in some ways, if you are new to coding, before you have that understanding of what is and isn't possible, anything is possible. And so, in some ways, I've worked with people who are super new to coding, and the ideas that they come up with for how to make a change at that highest level that you were just describing, in some ways, make sense. You can be like, oh yeah, that actually is something we can do and an idea that you might eventually get to from someone more experienced, having followed those different levels of progression and reaching a place where you're like, I know exactly what tools or the details about how to do this. But when you have that beginner's mind, and you don't have the details of the how, I think you can still think about those problems at a higher level, and that is valuable, and maybe they'll need help implementing along the way. And I think that that could be a really interesting area of collaboration that perhaps we don't do enough in this industry because it's very mentorship-focused where it's like, okay, I have more experience, and so I'm going to teach you what I know. Whereas if you bring someone with a totally fresh perspective along, what ideas can you generate from there? JOËL: I think we definitely exist in all of these layers every day as developers. I think, looking back at myself as a newer developer, I tended to maybe work bottom-up when I tried to solve a problem. And I think that now I probably tend to work sort of in the reverse order, start by thinking in terms of changes and then work my way down. And so syntax, at that point, is the last thing that I'm thinking about. It's really an implementation detail. Whereas I think as a new coder, syntax was super important. Was your experience similar to that, or did you have a very different journey? STEPHANIE: It's funny that you mentioned it because I think when I was new to development, there were so many syntactic things that I didn't understand that I just kind of like blurted out of my brain when I was reading code and was then trying to latch on to the important pieces of information that I needed to know, which often meant class names or method names. Pieces that I could grab onto and be like, okay, I'm seeing that this method then calls this other method or whatever. And, yeah, what you were saying about implementation details falling away, I kind of did that at the beginning of my career a little bit, at least at that syntactic level. So, yeah, I think I'm with you where we all exist at different parts of this framework, I suppose. And that journey could look different for everyone. JOËL: So we're talking about ways to be creative at higher levels. And one way that I find has been really fun for me but also really useful has been bringing in dependency graphs as a tool for design. You knew I had to mention dependency graphs. STEPHANIE: We got there in the end. [laughter] Cool, go on. JOËL: I think it's been really good sometimes in terms of modeling change sets because dependency graphs can be a great tool for that, but also sometimes in terms of trying to understand what the underlying business problem is and how it might translate into code structures where things might be tightly coupled versus not. And so, drawing it out visually is a really powerful design tool. And because now I can look at it in two-dimensional space, I can realize, oh, I see something that feels like it's maybe an anti-pattern or might be a problem here. There's a cycle in my graph; maybe we should find a way to break that. Maybe we need to introduce some dependency inversion and break that cycle, and now our graph is acyclic. And so I think that's where there can be a lot of creativity that happens, even when you're not writing code at that point. You're just sort of talking about how different pieces of the project or even different subproblems...you're not even talking about if they're implemented in code, but just saying this subproblem is related to this subproblem, and maybe I would like to find a way for them to not have a connection to each other. STEPHANIE: I'm glad we got back to this dependency graph topic because I stumbled upon something that I'm curious to hear your opinion on. I have been following Julia Evans' work for a little bit now. And she recently released a new zine about debugging. And at the end of the zine, she includes a link to these choose-your-own adventure puzzles that she has created, specifically to teach you about debugging and how to do it. And so it's basically a little detective game, and you kind of follow along with this bug. And she gives you some different options about how would you like to find a little bit more information about this bug? And what approach would you take? And you make some different selections, and then as you go, you get more information about the bug. And that helps inform what next steps you might take. And, one, I think this is a great example of a creative project about software development, even though it's not necessarily your day-to-day work. But then she also uses a tool called Twine, which is for creating non-linear stories, or puzzles, or games. And it got me really thinking about the multi-step wizard we've been talking about and this idea of looking at a problem in different mediums. It also reminds me of if you have a designer on your team and they're doing prototyping, they usually have some kind of user interactivity that they have to codify. And they are making those decisions about okay, like, if you are at this step, then where do you go next? And those are all things that you've talked about doing as a developer, I think, at a later point in the future lifecycle. And I'm now just kind of thinking about how to integrate some of that into our workflow. Do you have any thoughts about that? JOËL: I had one of the coolest experiences in my career when I was doing a front-end project where we were building a typeahead component that was pulling data from a remote server and then populating a drop-down. And the designer and I sat down and just started to look through all the different states that you could be and how you could move from one to another. So it looked like maybe you start the typeahead is empty; it's just a text box. And then as you start typing, maybe there's a spinner that shows up. And then maybe you have some results, or maybe you don't have results. And those are two different entirely states that you could be in. And then, if you backspace, what happens? And what if something goes wrong on the server? Like, we just kept finding all these edge cases. And we built out a diagram of all the possible journeys that someone could take, starting from that empty text box, all the way to either some sort of error state or a final state where you've selected an item. But, of course, these are not necessarily terminal because in an error state, maybe you can just start typing again, and you sort of jump back into the beginning of the flow. So we did this whole diagram that ended up looking very much like a finite-state machine. We didn't use the term, but that's kind of what it ended up being. And I think we both learned a lot about the problem we were trying to solve and the user experience we were trying to create through that. There was just a lot of back and forth of, like, oh, did you think about what would happen if we get no results here? Have we thought about that state? Or it's like, okay, so now we're in an error state. What do we do? Is there a way to get out of it, or are we just kind of stuck? Oh, you can backspace. Okay, what happens then? STEPHANIE: Yeah, I mean, we've been talking about creativity as a solitary process. But I think that that goes to show that when collaborating with other people, too, that process can also be very fun and creative and fulfill that need outside of the way the code is written. JOËL: In many ways, I think working with somebody else, and that gets made at the intersection of two or more people's work, is probably the most creative way to build software. STEPHANIE: That actually reminds me of a book I read last year called "Tomorrow, and Tomorrow, and Tomorrow." And it's about these two friends and their journey creating video games together. And it kind of follows several decades of their life and their relationship, and their creative and collaborative process. And I really loved that book. It was very good, especially if you like video games. There are a lot of great references to that too. But I think what you were saying about that fulfillment that you can get with working with other people, and that book does a really good job examining that and getting into our need as humans for that type of collaboration. So that's my little book rec. It goes back to our conversation about designing a game. Again, maybe this is [laughs] what we'll do next. Who knows? The world's our oyster. On that note, shall we wrap up? JOËL: Let's wrap up. STEPHANIE: Show notes for this episode can be found at bikeshed.fm. JOËL: This show has been produced and edited by Mandy Moore.

Thank you. ini2toml - Automatically translates .ini/.cfg files into TOML “… can also be used to convert any compatible .ini/.cfg file to TOML.” “ini2toml comes in two flavours: “lite” and “full”. The “lite” flavour will create a TOML document that does not contain any of the comments from the original .ini/.cfg file. On the other hand, the “full” flavour will make an extra effort to translate these comments into a TOML-equivalent (please notice sometimes this translation is not perfect, so it is always good to check the TOML document afterwards).” pyproject-fmt - Apply a consistent format to pyproject.toml files Having a consistent ordering and such is actually quite nice. I agreed with most changes when I tried it, except one change. The faulty change: it modified the name of my project. Not cool. pytest plugins are traditionally named pytest-something. the tool replaced the - with _. Wrong. So, be careful with adding this to your tool chain if you have intentional dashes in the name. Otherwise, and still, cool project. validate-pyproject - Automated checks on pyproject.toml powered by JSON Schema definitions It's a bit terse with errors, but still useful. $ validate-pyproject pyproject.toml Invalid file: pyproject.toml [ERROR] `project.authors[{data__authors_x}]` must be object $ validate-pyproject pyproject.toml Invalid file: pyproject.toml [ERROR] Invalid value (at line 3, column 12) I'd probably add tox Don't forget to build and test your project after making changes to pyproject.toml You'll catch things like missing dependencies that the other tools will miss.

Also feedback / rate us in your podcast player app Brian #1: Jupyter Games Thorsten Beier “Making their own tiny video games can be a great way for kids to learn programming in a playful matter.” For 2D physics-based games, Box2D, (written in C++), is a 2D rigid body simulation library One Python binding, pyb2d, is from Thorsten Game examples use Ipycanvas, Ipywidgets, and Ipyevents for a place to draw and input events. There are Box2D examples for physics simulations, like internal combustion and a wind tunnel. Game examples, with code, and not that much code billiards Angry Shapes (like Angry birds) World of Goo homage Rocket Color Mixing (it's oddly satisfying to play with, and it's like 73 lines of code, including blank lines and docstring) several more examples Demo games/examples in binder Being able to play with a game engine through Jupyter is kind of amazing. Cool teaching/learning tool. Michael #2: Canary Tokens First, what are canaries (from Thinkst)? These tokens might be useful for finding fallout of Log4Shell But also generally useful Kim #3: pywinauto and PyAutoGUI - libraries for programmatically controlling a GUI-based tool. These can be very handy for simplifying the use of complex GUIs with dozens of options you need to set every time you run them and also for automating GUI tooling as part of a pipeline. Brian #4: A reverse chronology of some Python features Brett Cannon Partly for people wishing for the “good old days” of some old version of Python Brett recommends going down the list and stopping at the first feature you can't live without. If you can't go very far, better not complain about language bloat. I had to stop at 3.10, since I really like the new error messages. Here's an abbreviated list of new features in different Python versions. (And I'm abbreviating it even more for the podcast) Python 3.10 Better error messages, Union operator for types, paraenthesized context managers, match statement (pattern matching) Brett notes that the match statement required a new parser for Python the new parser made better error messages possible so, you can't toss pattern matching without being willing to give up better error messages Python 3.9 dict support for | and |=, type hinting generics for built-in collections Python 3.8 f-string support for =, f``"``{val=}``", := walrus operator (assignment expressions) Python 3.7 dictionaries preserve insertion order, breakpoint() Python 3.6 f-strings, (need we say more) also underscores in numeric literals, async generators and comprehensions, preserving keyword argument order … goes back to 3.1 Michael #5: Hyperactive GCs and ORMs/ODMs Does Python do extremely too many GCs for ORMs? Hint: yes During the execution of that single query against SQLAlchemy, without adjusting Python's GC settings, we get an extreme number of GC collections (1,859 GCs for a single SQLAlchemy query of 20k records). Our fix at Talk Python has been to increase the number of surviving allocations required to force a GC from 700 to 50,000. What can be done to improve this? Maybe someday Python will have an adaptive GC where if it runs a collection and finds zero cycles it backs off and if it starts finding more cycles it ramps up or something like that. For now, test adjusting the thresholds Here are a few presentations / resources: Michael's presentation at Python Web Conf 2021 Talk Python Memory Deep Dive course allocations, gen1, gen2 = gc.get_threshold() # GC every 50K not 700 surviving container allocations. allocations = 50_000 gc.set_threshold(allocations, gen1, gen2) Kim #6: DockerSlim- A tool to reduce the size and improve the security of Docker images. I've used it a little and got some 1Gb Ubuntu-based images down to 50Mb and that was barely scratching the surface. Extras Michael: Emojis for comments Kim: python -m http.server - a small reminder to people that this is a quick way to get files off a Python-equipped system by standing up a simple web server. Mess with DNS - Julia Evans released this really impressive learning tool last week to let people explore DNS settings without breaking real sites. Magit - a slightly tongue-in-cheek addition to last week's discussion on git via both CLI and by mashing buttons in VS Code. Anyone using emacs should strongly consider magit for git - I've kept emacs open even while trying to use other editors because I find magit so indispensable. I've included these just as small items off the top of my head that may or may not be worth a mention.

Michael #2: Step-by-step guide to contributing on GitHub by Kevin Markham Want to contribute to an open source project? Follow this detailed visual guide to make your first contribution TODAY Although there are other guides like it out there, mine is (1) up-to-date with the latest GitHub interface, (2) much more detailed, and (3) highly visual. Includes 16 annotated screenshots + 2 workflow diagrams. The only prerequisite is that the reader has a tiny bit of Git knowledge. They don't even have to be a great coder, because what I suggest is that they start by fixing a typo or broken link in the documentation. That way they can focus on learning the contribution workflow! Steps: choose a project to contribute to fork the project clone your fork locally load your local copy in an editor make sure you have an "origin" remote add the project repository as the "upstream" remote pull the latest changes from upstream into your local repository create a new branch make changes in your local repository commit your changes push your changes to your fork create the pull request review the pull request add more commits to your pull request discuss the pull request delete your branch from your fork synchronize your fork with the project repository Nice Tips for contributing code section too. Brian #3: sneklang Snek: A Python-inspired Language for Embedded Devices An even smaller footprint than MicroPython or CircuitPython Can’t wait for Robot Inventor? Snek supports Lego EV3. “Snek is a tiny embeddable language targeting processors with only a few kB of flash and ram. … These processors are too small to run MicroPython.” Can develop using Mu editor Custom Snekboard runs either Snek or CircuitPython. Or run Snek on Lego EV3. Smaller language than Python, but intended to have all learning of Snek transferable to later development with Python. “The goals of the Snek language are: Text-based. A text-based language offers a richer environment for people comfortable with using a keyboard. It is more representative of real-world programming than building software using icons and a mouse. Forward-looking. Skills developed while learning Snek should be transferable to other development environments. Small. This is not just to fit in smaller devices: the Snek language should be small enough to teach in a few hours to people with limited exposure to software. Snek is Python-inspired, but it is not Python. It is possible to write Snek programs that run under a full Python system, but most Python programs will not run under Snek.” Michael #4: Oh sh*t git via Andrew Simon, by Julia Evans Does cost $10, no affiliations This zine explains git fundamentals (what’s a SHA?) How to fix a lot of common git mistakes (I committed to the wrong branch!!). Fundamentals Mistakes and how to fix them Merge conflicts Committed the wrong file Going back in time Brian #5: Why I don't like SemVer anymore Brett Cannon Interesting thoughts on SemVer SemVer isn't as straightforward as it sounds; we don't all agree on what a major, minor, or micro change really is.

At the time of this taping, Paul was in the middle of the Metis “bootcamp” program learning the capabilities, tools, and insights of data science. This conversation ranged widely in the realm of data analysis and management, examining its relevance to Paul’s field of geology but also exploring the world’s immersion in what Bill would call a data ecology: It seems every datum is connected, or connectable, to every other datum That word is the original singular form of the plural word “data.” The growing plethora of data has to be tracked and organized, even though today’s computer hardware doesn’t allow all the world’s data—or even relatively large slices of that data—to be stored and analyzed in one place at one time. Realizing that words are data, too, Paul pointed out that geology encountered a data explosion crisis a few decades ago as science developed enough new names for various rocks to make the new information less useful. That was until geologists produced a plan for sorting out and categorizing rock names according to rocks’ bulk chemistry instead of their constituent minerals (example here). Paul came to see the value of advanced organization in obtaining, thinking, and acting upon geological data—hence, his pursuit of this certificate in data science. Discussion of this specific field of science led to the use of various other terms, with various meanings, none of them fully understood by Bill. The terms included informatics, data scraping, the analysis of data clustering, “big data,” and “machine-learning algorithms.” These terms can be anticipated to be influential in nearly all fields, so it behooves the layperson to develop some familiarity with them. It is quite possible to become skeptical of such a body of knowledge and skills that can be used for benevolent or malevolent purposes, like everything. But Paul said the hopeful side of his personality recognizes what data scientists already recognize—namely, that this amazingly powerful field also has its limitation. He recalled there is an author who currently is writing books with a robust skepticism about machine-learning. Separately, one can get a laugh from the current results seen in the hybrid field of machine-learning poetry. Bill guessed the author was Julia Evans, but it was likely Janelle Shane, the author of You Look Like a Thing and I Love You. The bottom line is that, as with all science, its tools and results cannot provide their own guidance on how to use wisely the fruits they bear. The guidance must come from external forces driven by human virtue and values. Liner notes by Bill. Audio editing by Morgan. Cover art for this epsiode was produced by Paul... in conjunction with the Landsat 8 mission, the scikit-learn and seaborn libraries, and Mauna Loa and Kilauea volcanoes.

Give us some background on how you started taking this self-learning process and turning it into a visual medium?Topic 2 - You’ve recently been doing a bunch of work around HTTP. Most people know HTTP as the thing they type into a web-browser (sometimes). Let’s dig into why it might be important for people to know more about how the lifecycle of HTTP can impact their application performance.Topic 3 - Lots of the content we access on the Internet is stored/cached in CDNs around the world. Walk us through the basics of how CDNs work, and some of the interactions between HTTP and CDNs that can either improve performance or generally make an application’s life miserable. Topic 4 - Beyond CDNs, another big element that impacts HTTP traffic is load-balancers. Many people understand how basic IP-load balancing works, but how can it be different between L4 and L7 load-balancers? Topic 5 - Now how does encryption factor into all of this, as things like HTTP or TLS become part of the traffic?

Julia Evans, is a zine author and software engineer at Stripe. She joins us to talk about teaching specifics as opposed to high-level overviews, using zines to show that things that sound hard aren't hard in practice, the longevity of Julia's zine empire, and the impact that monetizing her zines had on her audience and the way she approaches working on them.Julia writes zines, short tutorials in comic form for software developers. She recently starting monetizing them, it had an impact on her audience but not as much as you would think. Monetizing even had the unforeseen side effect of her zines getting taken more seriously, a college professor even made then required reading in his class.She tries to keep the zines focused, with the topics breaking down something very particular. High levels talks often have the problem of not imparting anything useful. The specificity respects people's time and also can give greater context than a high-level overview. It's also much easier to be motivated to start a twenty-page zine as opposed to a three-hundred-page book.Julia has many ideas for her zine empire. She wants to continue to collaborate with other developers so she can deliver content that isn't entirely in her wheelhouse. She also wants to start getting into some non-programming concepts, statistics in particular at some point. The possibilities with the medium are pretty much endless.Transcript"Exploring Concepts and Teaching Using Focused Zines with Julia Evans" TranscriptResources:Wizard ZinesJulia Evans:TwitterGithubWebsiteJoel HooksTwitterWebsite

I figured Ruby should have it, too. 3:44 – Chuck talks about tools and Ruby Spy. 4:05 – Julia recommends it. Julia: You had to install the gem in order to use it. 4:30 – Chuck: some people say that it has affected their performance. 4:42 – Julia: Ruby Spy is a separate process. Julia continues this conversation and goes in-depth of what Ruby Spy is, etc. 5:27 – When would you use something like this, and what kind of data would get you back to debug the slow points. 5:43 – Julia: When you run Ruby Spy it will... 6:20 – Chuck: Does it give you method names? 6:25 – Julia: Yes, 20% in this method or... 6:37 – I can see how that would be helpful on certain aspects. Being able to narrow down the 1,000 methods where you cab get your biggest bang for your buck. 7:05 – Julia comments. 7:35 – Chuck: I know people pay for Relic... 7:56 – Chuck: When it tells you which method is taking a long time, will it look at the stack and THIS method is insufficient b/c this other method is insufficient? How does it do that? 8:35 – Julia answers the questions. 8:58 – Chuck: I’d imagine that it could keep anything in memory. Did you have to do a bunch of work where THAT means THAT? 9:20 – Julia answers. Julia: The differences weren’t that big between the different versions. 9:54 – Julia goes through the different ways the versions are different. 11:56 – Panelist asks a question. Is this meant for Ruby Scripts? 12:10 – Julia: It doesn’t care – as long as you are using the Ruby Interpreter. 12:25 – Chuck: Sometimes my performance issues is Ruby, and sometimes it’s the database. For Ruby it will sit there and wait for IO. Is that a blind spot that you will have in Ruby Spy? 12:54 – Julia: Great question. There are 2 ways to do profiling. Julia explains these two ways. 13:54 – Wall Clock Time. 14:04 – Chuck: Your computer has a speed and however long it takes to run one cycle. It is similar, but... 14:26 – I guess as long as it’s relative – I was looking at these graphs you wrote. 14:51 – Julia. 14:56 – Panelist: That has been my issue. Changing context into a profiler... 15:27 – Julia. 15:38 – Chuck: Do you have to run it through something...? 15:49 – Julia. 15:53 – Chuck: Is that the most effective way to look at the data through Ruby Spy? 16:07 – Julia: I twill show you the output as it is profiling. 2 visualizations: flame graph and... 16:45 – Chuck. 16:49 – Julia: It is the only visualization that I know of. 17:00 – Chuck: I don’t know. 17:05 – Julia: You have spent this amount of % to... How much time was spent in this function or that function? I feel that the flame graph is much more helpful than a list of percentages. 17:33 – Chuck: What are you looking at in the flame graph? 17:37 – Guest: Basically what time was spent in that function. You look at what is big, and then you figure out if that is something to optimize or not. You go to the docs and... 18:36 – Jackal. 18:40 – Main problem that I would run into is the information OVERLOAD. Now you have the action controllers and all these other components that aren’t normally visual. Panelist asks a question to Julia. 19:29 – Julia: It does give you everything. If you have a real serious problem often the answer will really jump out at you. What I would say – if something is really slow it is right there. 20:08 – Chuck: You will see the name of the method? 20:15 – Chuck: Any other information it will give you? 20:22 – Julia: The line number. 20:28 – Chuck asks another question. 20:41 – Chuck: Success stories? 20:45 – Julia: Yes, I do. GitHub – success stories. Julia gives us one of her success stories. This user said that it helped them by 30%. 21:28 – I can’t imagine using a Rail app that is over 10 years old. So much as changed! A lot of the documentation would be harder to find. 22:00 – Julia gives another example of a success story. 22:10 – When it goes to production – my brain turns off and get jittery. Figure out what happens in production and I wouldn’t want to guess for an app that couldn’t be down. This is what is happening right here and right now. 22:46 – Chuck: How do they get it out into production... 22:57 – Julia: Through GitHub that you can download. If you are on a Mac and your developing you can do it through Home Brew. 23:17 – Chuck and Julia go back and forth. 23:27 – Panelist: You don’t need to have it all the time, but a good tool. 23:44 – Julia: I want people to use it but not all the time; only when they need it. 23:58 – Panelist: I think on a lot of these scripts... Rails Panel – Panelist mentions this. 25:02 – Panelist asks her a question. 25:12 – Pie Spy is something else that someone wrote. 25:28 – Julia: Ruby Spy came first, and Pie Spy is inspired Ruby Spy. He did a good job building that. 25:50 – Advertisement – Code Badges 26:35 – People still use PHP? 26:42 – Julia: Yep! 26:47 – Chuck talks about his neighbor and how he raves about this feature or that feature. 27:07 – In PHP’s defense it has come a long way. I think they are at version 7 or version 8. Sounds like they did a lot of new things with the language. 27:31 – Julia: Instead of that or this language is better – what TOOLS can we use? I hear Ruby users make fun of Java, but Java has great tools. What can we learn from that language rather than bashing the other languages? 28:13 – Chuck chimes-in. Dot.net. 28:58 – Chuck: Let’s talk about that with the opensource. 29:09 – Julia talks about the opensource project. 30:30 – Julia: I asked my manager at Stripe to do this sabbatical in advance. I worked on it for 3 months. I got a check from Segment. 31:05 – Panelist adds in his comments and asks a question. 31:26 – Julia never used it. 31:32 – I have done a lot with Ruby Motion in the past. I am curious how that would work with Ruby Spy? 32:18 – IOS is pretty locked down, so I don’t think that would fly. 32:36 – Chuck talks about Ruby Motion and how he thinks Ruby Spy would / wouldn’t fit. 32:56 – What is funny about that, Chuck, is that you can ALT click... 34:07 – Chuck mentions another app. 34:17 – Julia. 34:40 – Chuck. 35:03 – Chuck: What else are you doing with Ruby Spy that is new? 35:05 – Julia: Not much. It’s fun to see people come in to make contributions. 35:33 – Panelist: Here is a suggestion, some kind of web server that you could... 35:57 – Great idea. 36:04 – Chuck: It wouldn’t be hard to embed it. 36:12 – Julia: Sharing it between...so we don’t have to build the same thing twice. 36:33 – Chuck and Julia go back-and-forth about Ruby Spy and Pie Spy, 37:23 – Julia: Pearl was my first language, and I still love it. 37:32 – Chuck: I guess I can’t knock it because I really haven’t tried it. 37:48 – Ruby was inspired by Pearl so there’s that. 37:57 – Chuck: How do people start using your tool?

RR 378: Ruby performance: MJIT with John Hawthorn

Ruby Rogues

Panel: Charles Max Wood David Richards Dave Kimura Eric Berry Special Guests: John Hawthorn In this episode of Ruby Rogues, the panel talks to John Hawthorn about MJIT. John has been a Ruby programmer for about 9 years and is based in Victoria, B.C. They talk about what MJIT is, the effects you can see from using the MJIT compiler, and why the JIT doesn’t always work with other languages. They also touch on how you can use the JIT in your own code, how he makes his performance better, and more! Show Topics: 1:36 – John is a Ruby programmer, and has been one for the past 9 years, and he is based out of Victoria, B.C. 5:00 – He had always been curious how a JIT would work and found that it was always too difficult to work with. Since discovering MJIT, he has been able to work with these compilers because he understands how to work with C code. 7:36 – Ruby has a bytecode and it looks a lot like an assembly language, which is approachable to a Rubyist. 8:24 – The core of MJIT is an ERB template which take this bytecode, loops over it, and emits C code. 9:01 – Effects that you can seem from the JIT in your own code is that it uses a really tight math loop, making your code faster. 11:25 – Other languages aren’t suited for compilers like JIT because they are so flexible to begin with.

Panel: Charles Max Wood David Richards Dave Kimura Eric Berry Special Guests: John Hawthorn In this episode of Ruby Rogues, the panel talks to John Hawthorn about MJIT. John has been a Ruby programmer for about 9 years and is based in Victoria, B.C. They talk about what MJIT is, the effects you can see from using the MJIT compiler, and why the JIT doesn’t always work with other languages. They also touch on how you can use the JIT in your own code, how he makes his performance better, and more! Show Topics: 1:36 – John is a Ruby programmer, and has been one for the past 9 years, and he is based out of Victoria, B.C. 5:00 – He had always been curious how a JIT would work and found that it was always too difficult to work with. Since discovering MJIT, he has been able to work with these compilers because he understands how to work with C code. 7:36 – Ruby has a bytecode and it looks a lot like an assembly language, which is approachable to a Rubyist. 8:24 – The core of MJIT is an ERB template which take this bytecode, loops over it, and emits C code. 9:01 – Effects that you can seem from the JIT in your own code is that it uses a really tight math loop, making your code faster. 11:25 – Other languages aren’t suited for compilers like JIT because they are so flexible to begin with. And in some cases, it doesn’t make sense to JIT compile. 13:05 – The compiled code now is not reusable by other workers and works better with one compilation per process. 15:20 – The temp folder gets cleared immediately after its run, but this compiled code is probably going to stay in memory forever. 17:30 – The MJIT doesn’t work as well with Rails because the code can’t get warmed up enough.

In this episode of Birth Kweens, Karly and Ali talk with the lovely Julia Evans about her two births. Julia had her first baby, Ollie, in an out-of-hospital birth center, and her second baby, Edie, was born at home. Karly was lucky enough to be present at both births, once as the birth assistant and once as the midwife. Ali and Karly talk with Julia about what it was like to have two unmedicated births, what made her choose a home birth the second time around, and what it’s like to reflect back on her birth experiences now that her kids are 8 and 10 years old. Julia also shares about experiencing a long and difficult back labor with her first, having a postpartum hemorrhage with her second, and bridging the gap between her pre-birth expectations and the realities of her birth experiences after it was all said and done. This is a really great episode full of candid stories and lots of laughs. We hope you enjoy it, kweens! --- Did you like this episode? Please subscribe, rate, review, and share!
