Brian #1: Coverage.py regex pragmas Ned Batchelder The regex implementation of how coverage.py recognizes pragmas is pretty amazing. It's extensible through plugins covdefaults adds a bunch of default exclusions, and also platform- and version-specific comment syntaxes. coverage-conditional-plugin gives you a way to create comment syntaxes for entire files, for whether other packages are installed, and so on. A change from last year (as part of coverage.py 7.6 allows multiline regexes, which let's us do things like: Exclude an entire file with A(?s:.*# pragma: exclude file.*)Z Allow start and stop delimiters with # no cover: start(?s:.*?)# no cover: stop Exclude empty placeholder methods with ^s*(((async )?def .*?)?)(s*->.*?)?:s*)?...s*(#|$) See Ned's article for explanations of these Michael #2: Python of Yore via Matthias Use YORE: ... comments to highlight CPython version dependencies. # YORE: EOL 3.8: Replace block with line 4. if sys.version_info < (3, 9): from astunparse import unparse else: from ast import unparse Then check when they go out of support: $ yore check --eol-within '5 months' ./src/griffe/agents/nodes/_values.py:11: Python 3.8 will reach its End of Life within approx. 4 months Even fix them with fix . Michael #3: nox-uv via John Hagen What nox-uv does is make it very simple to install uv extras and/or dependency groups into a nox session's virtual environment. The versions installed are constrained by uv's lockfile meaning that everything is deterministic and pinned. Dependency groups make it very easy to install only want is necessary for a session (e.g., only linting dependencies like Ruff, or main dependencies + mypy for type checking). Brian #4: A couple Django items Stop Using Django's squashmigrations: There's a Better Way Johnny Metz Resetting migrations is sometimes the right thing. Overly simplified summary: delete migrations and start over dj-lite Adam Hill Use SQLite in production with Django “Simplify deploying and maintaining production Django websites by using SQLite in production. dj-lite helps enable the best performance for SQLite for small to medium-sized projects. It requires Django 5.1+.” Extras Brian: Test & Code 237: FastAPI Cloud with Sebastian Ramirez will be out later today pythontest.com: pytest fixtures nuts and bolts - revisited A blog series that I wrote a long time ago.

Fredrik talks to Matt Topol about Arrow and how the Arrow ecosystem is evolving. Arrow is an open source, columnar in-memory data format designed for efficient data processing and analytics - which means passing data between things without needing to transform it, and ideally even without needing to copy it. What makes the ecosystem grow, and why is it very cool to have Arrow on the GPU? What is the connection between Arrow, machine learning, and Hugging face? Matt emphasizes the value of open standards, even as they work with or within more closed systems they can help open things up, and help bring about more modular solutions so that developers can focus on doing their core area really well. This episode can be seen as a follow-up to episode 567, where Matt first joined to discuss everything Arrow. Recorded during Øredev 2024. Thank you Cloudnet for sponsoring our VPS!

[podcastsponsor] Machine-Generated Transcript What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for listening to the episode. Christopher S. Penn – 00:00 In this week’s In-Ear Insights, if you go on LinkedIn, everybody, including tons of non-coding folks, has jumped into vibe coding, the term coined by OpenAI co-founder Andre Karpathy. A lot of people are doing some really cool stuff with it. However, a lot of people are also, as you can see on X in a variety of posts, finding out the hard way that if you don’t know what to ask for—say, application security—bad things can happen. Katie, how are you doing with giving into the vibes? Katie Robbert – 00:38 I’m not. I’ve talked about this on other episodes before. For those who don’t know, I have an extensive background in managing software development. I myself am not a software developer, but I have spent enough time building and managing those teams that I know what to look for and where things can go wrong. I’m still really skeptical of vibe coding. We talked about this on a previous podcast, which if you want to find our podcast, it’s @TrustInsightsAI_TIpodcast, or you can watch it on YouTube. My concern, my criticism, my skepticism of vibe coding is if you don’t have the basic foundation of the SDLC, the software development lifecycle, then it’s very easy for you to not do vibe coding correctly. Katie Robbert – 01:42 My understanding is vibe coding is you’re supposed to let the machine do it. I think that’s a complete misunderstanding of what’s actually happening because you still have to give the machine instruction and guardrails. The machine is creating AI. Generative AI is creating the actual code. It’s putting together the pieces—the commands that comprise a set of JSON code or Python code or whatever it is you’re saying, “I want to create an app that does this.” And generative AI is like, “Cool, let’s do it.” You’re going through the steps. You still need to know what you’re doing. That’s my concern. Chris, you have recently been working on a few things, and I’m curious to hear, because I know you rely on generative AI because yourself, you’ve said, are not a developer. What are some things that you’ve run into? Katie Robbert – 02:42 What are some lessons that you’ve learned along the way as you’ve been vibing? Christopher S. Penn – 02:50 Process is the foundation of good vibe coding, of knowing what to ask for. Think about it this way. If you were to say to Claude, ChatGPT, or Gemini, “Hey, write me a fiction novel set in the 1850s that’s a drama,” what are you going to get? You’re going to get something that’s not very good. Because you didn’t provide enough information. You just said, “Let’s do the thing.” You’re leaving everything up to the machine. That prompt—just that prompt alone. If you think about an app like a book, in this example, it’s going to be slop. It’s not going to be very good. It’s not going to be very detailed. Christopher S. Penn – 03:28 Granted, it doesn’t have the issues of code, but it’s going to suck. If, on the other hand, you said, “Hey, here’s the ideas I had for all the characters, here’s the ideas I had for the plot, here’s the ideas I had for the setting. But I want to have these twists. Here’s the ideas for the readability and the language I want you to use.” You provided it with lots and lots of information. You’re going to get a better result. You’re going to get something—a book that’s worth reading—because it’s got your ideas in it, it’s got your level of detail in it. That’s how you would write a book. The same thing is true of coding. You need to have, “Here’s the architecture, here’s the security requirements,” which is a big, big gap. Christopher S. Penn – 04:09 Here’s how to do unit testing, here’s the fact why unit tests are important. I hated when I was writing code by myself, I hated testing. I always thought, Oh my God, this is the worst thing in the world to have to test everything. With generative AI coding tools, I now am in love with testing because, in fact, I now follow what’s called test-driven development, where you write the tests first before you even write the production code. Because I don’t have to do it. I can say, “Here’s the code, here’s the ideas, here’s the questions I have, here’s the requirements for security, here’s the standards I want you to use.” I’ve written all that out, machine. “You go do this and run these tests until they’re clean, and you’ll just keep running over and fix those problems.” Christopher S. Penn – 04:54 After every cycle you do it, but it has to be free of errors before you can move on. The tools are very capable of doing that. Katie Robbert – 05:03 You didn’t answer my question, though. Christopher S. Penn – 05:05 Okay. Katie Robbert – 05:06 My question to you was, Chris Penn, what lessons have you specifically learned about going through this? What’s been going on, as much as you can share, because obviously we’re under NDA. What have you learned? Christopher S. Penn – 05:23 What I’ve learned: documentation and code drift very quickly. You have your PRD, you have your requirements document, you have your work plans. Then, as time goes on and you’re making fixes to things, the code and the documentation get out of sync very quickly. I’ll show an example of this. I’ll describe what we’re seeing because it’s just a static screenshot, but in the new Claude code, you have the ability to build agents. These are built-in mini-apps. My first one there, Document Code Drift Auditor, goes through and says, “Hey, here’s where your documentation is out of line with the reality of your code,” which is a big deal to make sure that things stay in sync. Christopher S. Penn – 06:11 The second one is a Code Quality Auditor. One of the big lessons is you can’t just say, “Fix my code.” You have to say, “You need to give me an audit of what’s good about my code, what’s bad about my code, what’s missing from my code, what’s unnecessary from my code, and what silent errors are there.” Because that’s a big one that I’ve had trouble with is silent errors where there’s not something obviously broken, but it’s not quite doing what you want. These tools can find that. I can’t as a person. That’s just me. Because I can’t see what’s not there. A third one, Code Base Standards Inspector, to look at the standards. This is one that it says, “Here’s a checklist” because I had to write—I had to learn to write—a checklist of. Christopher S. Penn – 06:51 These are the individual things I need you to find that I’ve done or not done in the codebase. The fourth one is logging. I used to hate logging. Now I love logs because I can say in the PRD, in the requirements document, up front and throughout the application, “Write detailed logs about what’s happening with my application” because that helps machine debug faster. I used to hate logs, and now I love them. I have an agent here that says, “Go read the logs, find errors, fix them.” Fifth lesson: debt collection. Technical debt is a big issue. This is when stuff just accumulates. As clients have new requests, “Oh, we want to do this and this and this.” Your code starts to drift even from its original incarnation. Christopher S. Penn – 07:40 These tools don’t know to clean that up unless you tell it to. I have a debt collector agent that goes through and says, “Hey, this is a bunch of stuff that has no purpose anymore.” And we can then have a conversation about getting rid of it without breaking things. Which, as a thing, the next two are painful lessons that I’ve learned. Progress Logger essentially says, after every set of changes, you need to write a detailed log file in this folder of that change and what you did. The last one is called Docs as Data Curator. Christopher S. Penn – 08:15 This is where the tool goes through and it creates metadata at the top of every progress entry that says, “Here’s the keywords about what this bug fixes” so that I can later go back and say, “Show me all the bug fixes that we’ve done for BigQuery or SQLite or this or that or the other thing.” Because what I found the hard way was the tools can introduce regressions. They can go back and keep making the same mistake over and over again if they don’t have a logbook of, “Here’s what I did and what happened, whether it worked or not.” By having these set—these seven tools, these eight tools—in place, I can prevent a lot of those behaviors that generative AI tends to have. Christopher S. Penn – 08:54 In the same way that you provide a writing style guide so that AI doesn’t keep making the mistake of using em dashes or saying, “in a world of,” or whatever the things that you do in writing. My hard-earned lessons I’ve encoded into agents now so that I don’t keep making those mistakes, and AI doesn’t keep making those mistakes. Katie Robbert – 09:17 I feel you’re demonstrating my point of my skepticism with vibe coding because you just described a very lengthy process and a lot of learnings. I’m assuming what was probably a lot of research up front on software development best practices. I actually remember the day that you were introduced to unit tests. It wasn’t that long ago. And you’re like, “Oh, well, this makes it a lot easier.” Those are the kinds of things that, because, admittedly, software development is not your trade, it’s not your skillset. Those are things that you wouldn’t necessarily know unless you were a software developer. Katie Robbert – 10:00 This is my skepticism of vibe coding: sure, anybody can use generative AI to write some code and put together an app, but then how stable is it, how secure is it? You still have to know what you’re doing. I think that—not to be too skeptical, but I am—the more accessible generative AI becomes, the more fragile software development is going to become. It’s one thing to write a blog post; there’s not a whole lot of structure there. It’s not powering your website, it’s not the infrastructure that holds together your entire business, but code is. Katie Robbert – 11:03 That’s where I get really uncomfortable. I’m fine with using generative AI if you know what you’re doing. I have enough knowledge that I could use generative AI for software development. It’s still going to be flawed, it’s still going to have issues. Even the most experienced software developer doesn’t get it right the first time. I’ve never in my entire career seen that happen. There is no such thing as the perfect set of code the first time. I think that people who are inexperienced with the software development lifecycle aren’t going to know about unit tests, aren’t going to know about test-based coding, or peer testing, or even just basic QA. Katie Robbert – 11:57 It’s not just, “Did it do the thing,” but it’s also, “Did it do the thing on different operating systems, on different browsers, in different environments, with people doing things you didn’t ask them to do, but suddenly they break things?” Because even though you put the big “push me” button right here, someone’s still going to try to click over here and then say, “I clicked on your logo. It didn’t work.” Christopher S. Penn – 12:21 Even the vocabulary is an issue. I’ll give you four words that would automatically uplevel your Python vibe coding better. But these are four words that you probably have never heard of: Ruff, MyPy, Pytest, Bandit. Those are four automated testing utilities that exist in the Python ecosystem. They’ve been free forever. Ruff cleans up and does linting. It says, “Hey, you screwed this up. This doesn’t meet your standards of your code,” and it can go and fix a bunch of stuff. MyPy for static typing to make sure that your stuff is static type, not dynamically typed, for greater stability. Pytest runs your unit tests, of course. Bandit looks for security holes in your Python code. Christopher S. Penn – 13:09 If you don’t know those exist, you probably say you’re a marketer who’s doing vibe coding for the first time, because you don’t know they exist. They are not accessible to you, and generative AI will not tell you they exist. Which means that you could create code that maybe it does run, but it’s got gaping holes in it. When I look at my standards, I have a document of coding standards that I’ve developed because of all the mistakes I’ve made that it now goes in every project. This goes, “Boom, drop it in,” and those are part of the requirements. This is again going back to the book example. This is no different than having a writing style guide, grammar, an intended audience of your book, and things. Christopher S. Penn – 13:57 The same things that you would go through to be a good author using generative AI, you have to do for coding. There’s more specific technical language. But I would be very concerned if anyone, coder or non-coder, was just releasing stuff that didn’t have the right safeguards in it and didn’t have good enough testing and evaluation. Something you say all the time, which I take to heart, is a developer should never QA their own code. Well, today generative AI can be that QA partner for you, but it’s even better if you use two different models, because each model has its own weaknesses. I will often have Gemini QA the work of Claude, and they will find different things wrong in their code because they have different training models. These two tools can work together to say, “What about this?” Christopher S. Penn – 14:48 “What about this?” And they will. I’ve actually seen them argue, “The previous developers said this. That’s not true,” which is entertaining. But even just knowing that rule exists—a developer should not QA their own code—is a blind spot that your average vibe coder is not going to have. Katie Robbert – 15:04 Something I want to go back to that you were touching upon was the privacy. I’ve seen a lot of people put together an app that collects information. It could collect basic contact information, it could collect other kind of demographic information, it can collect opinions and thoughts, or somehow it’s collecting some kind of information. This is also a huge risk area. Data privacy has always been a risk. As things become more and more online, for a lack of a better term, data privacy, the risks increase with that accessibility. Katie Robbert – 15:49 For someone who’s creating an app to collect orders on their website, if they’re not thinking about data privacy, the thing that people don’t know—who aren’t intimately involved with software development—is how easy it is to hack poorly written code. Again, to be super skeptical: in this day and age, everything is getting hacked. The more AI is accessible, the more hackable your code becomes. Because people can spin up these AI agents with the sole purpose of finding vulnerabilities in software code. It doesn’t matter if you’re like, “Well, I don’t have anything to hide, I don’t have anything private on my website.” It doesn’t matter. They’re going to hack it anyway and start to use it for nefarious things. Katie Robbert – 16:49 One of the things that we—not you and I, but we in my old company—struggled with was conducting those security tests as part of the test plan because we didn’t have someone on the team at the time who was thoroughly skilled in that. Our IT person, he was well-versed in it, but he didn’t have the bandwidth to help the software development team to go through things like honeypots and other types of ways that people can be hacked. But he had the knowledge that those things existed. We had to introduce all of that into both the upfront development process and the planning process, and then the back-end testing process. It added additional time. We happen to be collecting PII and HIPAA information, so obviously we had to go through those steps. Katie Robbert – 17:46 But to even understand the basics of how your code can be hacked is going to be huge. Because it will be hacked if you do not have data privacy and those guardrails around your code. Even if your code is literally just putting up pictures on your website, guess what? Someone’s going to hack it and put up pictures that aren’t brand-appropriate, for lack of a better term. That’s going to happen, unfortunately. And that’s just where we’re at. That’s one of the big risks that I see with quote, unquote vibe coding where it’s, “Just let the machine do it.” If you don’t know what you’re doing, don’t do it. I don’t know how many times I can say that, or at the very. Christopher S. Penn – 18:31 At least know to ask. That’s one of the things. For example, there’s this concept in data security called principle of minimum privilege, which is to grant only the amount of access somebody needs. Same is true for principle of minimum data: collect only information that you actually need. This is an example of a vibe-coded project that I did to make a little Time Zone Tracker. You could put in your time zones and stuff like that. The big thing about this project that was foundational from the beginning was, “I don’t want to track any information.” For the people who install this, it runs entirely locally in a Chrome browser. It does not collect data. There’s no backend, there’s no server somewhere. So it stays only on your computer. Christopher S. Penn – 19:12 The only thing in here that has any tracking whatsoever is there’s a blue link to the Trust Insights website at the very bottom, and that has Google Track UTM codes. That’s it. Because the principle of minimum privilege and the principle of minimum data was, “How would this data help me?” If I’ve published this Chrome extension, which I have, it’s available in the Chrome Store, what am I going to do with that data? I’m never going to look at it. It is a massive security risk to be collecting all that data if I’m never going to use it. It’s not even built in. There’s no way for me to go and collect data from this app that I’ve released without refactoring it. Christopher S. Penn – 19:48 Because we started out with a principle of, “Ain’t going to use it; it’s not going to provide any useful data.” Katie Robbert – 19:56 But that I feel is not the norm. Christopher S. Penn – 20:01 No. And for marketers. Katie Robbert – 20:04 Exactly. One, “I don’t need to collect data because I’m not going to use it.” The second is even if you’re not collecting any data, is your code still hackable so that somebody could hack into this set of code that people have running locally and change all the time zones to be anti-political leaning, whatever messages that they’re like, “Oh, I didn’t realize Chris Penn felt that way.” Those are real concerns. That’s what I’m getting at: even if you’re publishing the most simple code, make sure it’s not hackable. Christopher S. Penn – 20:49 Yep. Do that exercise. Every software language there is has some testing suite. Whether it’s Chrome extensions, whether it’s JavaScript, whether it’s Python, because the human coders who have been working in these languages for 10, 20, 30 years have all found out the hard way that things go wrong. All these automated testing tools exist that can do all this stuff. But when you’re using generative AI, you have to know to ask for it. You have to say. You can say, “Hey, here’s my idea.” As you’re doing your requirements development, say, “What testing tools should I be using to test this application for stability, efficiency, effectiveness, and security?” Those are the big things. That has to be part of the requirements document. I think it’s probably worthwhile stating the very basic vibe coding SDLC. Christopher S. Penn – 21:46 Build your requirements, check your requirements, build a work plan, execute the work plan, and then test until you’re sick of testing, and then keep testing. That’s the process. AI agents and these coding agents can do the “fingers on keyboard” part, but you have to have the knowledge to go, “I need a requirements document.” “How do I do that?” I can have generative AI help me with that. “I need a work plan.” “How do I do that?” Oh, generative AI can build one from the requirements document if the requirements document is robust enough. “I need to implement the code.” “How do I do that?” Christopher S. Penn – 22:28 Oh yeah, AI can do that with a coding agent if it has a work plan. “I need to do QA.” “How do I do that?” Oh, if I have progress logs and the code, AI can do that if it knows what to look for. Then how do I test? Oh, AI can run automated testing utilities and fix the problems it finds, making sure that the code doesn’t drift away from the requirements document until it’s done. That’s the bare bones, bare minimum. What’s missing from that, Katie? From the formal SDLC? Katie Robbert – 23:00 That’s the gist of it. There’s so much nuance and so much detail. This is where, because you and I, we were not 100% aligned on the usage of AI. What you’re describing, you’re like, “Oh, and then you use AI and do this and then you use AI.” To me, that immediately makes me super anxious. You’re too heavily reliant on AI to get it right. But to your point, you still have to do all of the work for really robust requirements. I do feel like a broken record. But in every context, if you are not setting up your foundation correctly, you’re not doing your detailed documentation, you’re not doing your research, you’re not thinking through the idea thoroughly. Katie Robbert – 23:54 Generative AI is just another tool that’s going to get it wrong and screw it up and then eventually collect dust because it doesn’t work. When people are worried about, “Is AI going to take my job?” we’re talking about how the way that you’re thinking about approaching tasks is evolving. So you, the human, are still very critical to this task. If someone says, “I’m going to fire my whole development team, the machines, Vibe code, good luck,” I have a lot more expletives to say with that, but good luck. Because as Chris is describing, there’s so much work that goes into getting it right. Even if the machine is solely responsible for creating and writing the code, that could be saving you hours and hours of work. Because writing code is not easy. Katie Robbert – 24:44 There’s a reason why people specialize in it. There’s still so much work that has to be done around it. That’s the thing that people forget. They think they’re saving time. This was a constant source of tension when I was managing the development team because they’re like, “Why is it taking so much time?” The developers have estimated 30 hours. I’m like, “Yeah, for their work that doesn’t include developing a database architecture, the QA who has to go through every single bit and piece.” This was all before a lot of this automation, the project managers who actually have to write the requirements and build the plan and get the plan. All of those other things. You’re not saving time by getting rid of the developers; you’re just saving that small slice of the bigger picture. Christopher S. Penn – 25:38 The rule of thumb, generally, with humans is that for every hour of development, you’re going to have two to four hours of QA time, because you need to have a lot of extra eyes on the project. With vibe coding, it’s between 10 and 20x. Your hour of vibe coding may shorten dramatically. But then you’re going to. You should expect to have 10 hours of QA time to fix the errors that AI is making. Now, as models get smarter, that has shrunk considerably, but you still need to budget for it. Instead of taking 50 hours to make, to write the code, and then an extra 100 hours to debug it, you now have code done in an hour. But you still need the 10 to 20 hours to QA it. Christopher S. Penn – 26:22 When generative AI spits out that first draft, it’s every other first draft. It ain’t done. It ain’t done. Katie Robbert – 26:31 As we’re wrapping up, Chris, if possible, can you summarize your recent lesson learned from using AI for software development—what is the one thing, the big lesson that you took away? Christopher S. Penn – 26:50 If we think of software development like the floors of a skyscraper, everyone wants the top floor, which is the scenic part. That’s cool, and everybody can go up there. It is built on a foundation and many, many floors of other things. And if you don’t know what those other floors are, your top floor will literally fall out of the sky. Because it won’t be there. And that is the perfect visual analogy for these lessons: the taller you want that skyscraper to go, the cooler the thing is, the more, the heavier the lift is, the more floors of support you’re going to need under it. And if you don’t have them, it’s not going to go well. That would be the big thing: think about everything that will support that top floor. Christopher S. Penn – 27:40 Your overall best practices, your overall coding standards for a specific project, a requirements document that has been approved by the human stakeholders, the work plans, the coding agents, the testing suite, the actual agentic sewing together the different agents. All of that has to exist for that top floor, for you to be able to build that top floor and not have it be a safety hazard. That would be my parting message there. Katie Robbert – 28:13 How quickly are you going to get back into a development project? Christopher S. Penn – 28:19 Production for other people? Not at all. For myself, every day. Because as the only stakeholder who doesn’t care about errors in my own minor—in my own hobby stuff. Let’s make that clear. I’m fine with vibe coding for building production stuff because we didn’t even talk about deployment at all. We touched on it. Just making the thing has all these things. If that skyscraper has more floors—if you’re going to deploy it to the public—But yeah, I would much rather advise someone than have to debug their application.

Michael #1: Distributed sqlite follow up: Turso and Litestream Michael Booth: Turso marries the familiarity and simplicity of SQLite with modern, scalable, and distributed features. Seems to me that Turso is to SQLite what MotherDuck is to DuckDB. Mike Fiedler Continue to use the SQLite you love and care about (even the one inside Python runtime) and launch a daemon that watches the db for changes and replicates changes to an S3-type object store. Deeper dive: Litestream: Revamped Brian #2: PEP 792 – Project status markers in the simple index Currently 3 status markers for packages Trove Classifier status Indices can be yanked PyPI projects - admins can quarantine a project, owners can archive a project Proposal is to have something that can have only one state active archived quarantined deprecated This has been Approved, but not Implemented yet.

Three Buddy Problem - Episode 54: Europol busted pro‑Russian hacktivist crew NoName 057(16), the Brits announce sanctions on Russia's GRU cyber units, Wagner‑linked “war influencers” streamed atrocities from Africa, and fresh tech worries ranged from a $500 RF flaw that can hijack U.S. train brakes. Plus, ProPublica on Microsoft's China‑based “digital escorts,” Google's headline‑grabbing AI‑found SQLite zero‑day, and OpenAI's new task‑running agents. Meanwhile, Ukraine's hackers wiped a Russian drone maker, ransomware crippled a major vodka producer, and another Chrome zero‑day quietly underscored how routine critical exploits have become.

Add your name and email to our friends of the show list, we'll never share it. Brian #1: Switching to direnv, Starship, and uv Last week I mentioned that I'm ready to try direnv again, but secretly, I still had some worries about the process. Thankfully, Trey has a tutorial to walk me past the troublesome parts. direnv - an extension for your shell. It augments existing shells with a new feature that can load and unload environment variables depending on the current directory. Switching from virtualenvwrapper to direnv, Starship, and uv - Trey Hunner** Trey has solved a bunch of the problems I had when I tried direnv before Show the virtual environment name in the prompt Place new virtual environments in local .venv instead of in .direnv/python3.12 Silence all of the “loading”, “unloading” statements every time you enter a directory Have a script called venv to create an environment, activate it, create a .envrc file I'm more used to a create script, so I'll stick with that name and Trey's contents A workon script to be able to switch around to different projects. This is a carry over from “virtualenvwrapper', but seems cool. I'll take it. Adding uv to the mix for creating virtual environments. Interestingly including --seed which, for one, installs pip in the new environment. (Some tools need it, even if you don't) Starship Trey also has some setup for Starship. But I'll get through the above first, then MAYBE try Starship again. Some motivation Trey's setup is pretty simple. Maybe I was trying to get too fancy before Starship config in toml files that can be loaded with direnv and be different for different projects. Neato Also, Trey mentions his dotfiles repo. This is a cool idea that I've been meaning to do for a long time. See also: It's Terminal - Bootstrapping With Starship, Just, Direnv, and UV - Mario Munoz Michael #2: rqlite - Distributed SQLite DB via themlu, thanks! rqlite is a lightweight, user-friendly, distributed relational database built on SQLite. Built on SQLite, the world's most popular database Supports full-text search, Vector Search, and JSON documents Access controls and encryption for secure deployments Michael #3: A Python dict that can report which keys you did not use by Peter Bengtsson Very cool for testing that a dictionary has been used as expected (e.g. all data has been sent out via an API or report). Note: It does NOT track d.get(), but it's easy to just add it to the class in the post. Maybe someone should polish it up and put it on pypi (that person is not me :) ). Brian #4: Some Markdown Stuff Textual 4.0.0 adds Markdown.append which can be used to efficiently stream markdown content The reason for the major bump is due to an interface change to Widget.anchor Refreshing to see a symantic change cause a major version bump. html-to-markdown Converts html to markdown A complete rewrite fork of markdownify Lots of fun features like “streaming support” Curious if it can stream to Textual's Markdown.append method. hmmm.

本期节目应嘉宾的要求，我们只发布了文字稿。带来的不便还请各位听众谅解。 嘉宾 tanloong 链接 gh-133390: Support SQL keyword completion for sqlite3 CLI by tanloong · Pull Request #133393 · python/cpython SQLite Keywords QuantWiki - 中文量化百科 《阳光马达棒球场！》 文字稿 laike9m: 哈喽大家好，欢迎来到最新一期的《捕蛇者说》。我们今天请到了谭龙，然后让他来聊一聊给 CPython 做贡献的经历。谭龙其实最近给 CPython 提了一个 PR，然后也是他第一次给 CPython 做贡献。然后呢，这个贡献是给 SQLite 的那个命令行加了一些命令补全，就是可以补全 SQLite 的关键字。我们今天另外一位主播是 Manjusaka。 Manjusaka: 请叫我 Nadeshiko Manju，对吧？OK，大家好，好久不见，我又回来了。然后今天很高兴又来和 laike9m 进行搭档，来。 laike9m: 好，然后这是我们今天的嘉宾谭龙，你要不先简单介绍一下自己吧。 tanloong: Hello，大家好，我叫谭龙，我是山东的。然后 18 年的时候是来青岛上大学，然后大学本科毕业之后就在这找工作了。我本科不是计算机的，毕业之后找工作也找了一些计算机相关的工作，也有一些其他方面的工作，中间也换了好几次工作。最近是刚刚入职一家新的公司，然后是做数据分析方面的工作。谢谢。 laike9m: 所以你说你本科不是学计算机，方便透露一下吗？你本科学的是什么？ tanloong: 我本科是英语的。 laike9m: 哦，这个跨度很大。 tanloong: 对，确实。其实我本科最开始填志愿的时候，我录取的专业也不是英语，是一个调剂的专业，叫生态学。然后我是大一下学期的时候想转专业，然后正好我们学校有转专业的政策，我就从高中学的那几门课里，我觉得英语我学得还可以，然后当时也比较喜欢，所以我就决定转英语了。直到后来快毕业的时候才有点接触到这个计算机方面的这个东西。 laike9m: 然后就发现自己还是更喜欢计算机一些。那所以你之后是进行一些自学吗？然后就去找工作还是？ tanloong: 对，基本上是自学。最开始接触计算机是大一的寒假，我们辅导员让学生回家的时候在假期要学点东西，然后开学让交学习笔记。我当时从一个中国大学 MOOC 上注册了一个账号，然后它弹出来的，第一个给我推荐的课程就是 Python。那我就学这个吧。所以当时我就学，就学了这个。当时学得很不明白，然后就把 PPT 跟着敲了一遍，但是也云里雾里的。直到后来后面的几个寒暑假才看了一些成体系的 Python 的入门的书，然后算是入门 Python 了。 laike9m: 所以换句话说就是你其实一开始学，你并不知道 Python 是干嘛的，就是并没有特别地抱着某种目的，比如说我就想找一个程序员的工作这样子。 tanloong: 没有，开始的原因只是巧合，但后面坚持下来，应该也算是因为比较喜欢吧。我觉得比较有意思。 laike9m: 那还是挺有意思的，对，感觉是命运的安排。 Manjusaka: 咱行看起来都是转行的。诶，那 laike9m 你是转行吗？ laike9m: 我本科也不是学计算机的，然后我知道你本科也不是，所以。 Manjusaka: 对，那看起来大家这三个人跟少女乐队一样，这三个人里面抽不出一张计算机本科学位。 laike9m: 对，但我觉得还是你的英语这个跨度最大。 Manjusaka: 啊，对，然后，哇，卧槽。啊，现在要是学日语的，我突然就想问一下为什么要学日语。 laike9m: 学日语的转计算机还真没见过，但是很多程序员都会日语。 Manjusaka: 有，可能在大连那边还真有。 laike9m: 啊，对，大连日本人比较多。 Manjusaka: 对，对，对，日语外包会多一些。 laike9m: 嗯，好，对，说回正题，就是你相当于一开始接触的编程语言就是 Python, 然后后来相当于你在工作中可以理解也是主要用 Python, 对吗？ tanloong: 对的，我有两份工作是跟计算机相关，然后都是写 Python 的。第一个工作是之前的一份是写图形界面的，用的是 PySide, 然后就写一个称重系统。他们是一个建桥公司，就是他们需要统计他们的货车送多少货进他们工厂，然后运多少货出来，写一个这个图形界面，然后放在那个他们的磅站去，然后货车过磅的时候来统计数据。另一个工作是现在的工作是在一个私募公司做数据分析。我之前没接触过股票证券这方面的东西，现在还在学习。 laike9m: 你是开发算法吗，还是给他们开发一些内部工具或者界面之类的？ tanloong: 内部工具，我们组三个人有写算法的，但是我是属于比较初级的那种，只能写一些帮他们节省时间的工具。 laike9m: OK，对，因为我感觉那种像交易的算法可能更需要用 C++ 一些，对吧？还是说其实也有用 Python，比较好奇。 tanloong: 我们公司开发部应该是写 C++ 的，然后应该也有写 Python, 但是数据分析我们那个组主要是做一些因子的构建，就分析哪些因子它对你的这个股票的收益率贡献比较大，就这种的，我们就主要是写 Python，不写 C++。 laike9m: 明白，好的。所以就是到了今天我们要聊这个话题，然后你给 CPython 做了一个贡献。那我相信就是百分之可能 99.99% 的用过 Python 的人都没有给 Python 做过贡献，那么你一开始是怎么有这个想法的？然后就是后来你是怎么去一步一步实施这个的？ tanloong: 我最开始有这个想法是应该从天哥，就是 B 站的那个，对，他当时成为 Python Core Dev 之后，在直播的时候就有人在直播间问一个给 Python 做贡献的问题，做贡献难不难呢？这些之类的。但是天哥说，如果你想给 Python 做贡献，你是会发现有很多事可以做的，做贡献并不难。然后后来就是之前我在写称重系统的时候，需要用到 SQLite 去查用户存的那个本地的数据库。然后当时我就发现 Python 的 SQLite 的命令行界面有点不好使，就是如果它能有那个补全就好了，所以当时是有那个想法。然后实施是在后来我前段时间没有工作，然后就每天比较闲，然后我想找点事做，然后我想起来之前我想给那个 SQLite 的加补全的这个想法，我就试试吧。然后我就去 GitHub 上找，我就试了一下。然后试的时候我发现，我本来觉得这个应该是挺难的，因为我完全不知道它这个补全要怎么实现。但是我去看了一下 PDB，就是天哥维护的那个 PDB 里面的代码，它里面实现补全是那样写的，然后我就照着 PDB 的补全，然后给 SQLite 加了一个补全，然后就交了 PR。 laike9m: 所以其实也是从你的实际工作需求出发，然后加上高天的激励。对，你知道高天也来过我们这边好几次吧？ tanloong: 对，两次。 laike9m: 老听众，看来是。对，然后我觉得这个还挺有意思，就是也是算是榜样的力量吧。就是我不知道还有没有其他人是这样，就是因为听到就是有个人跟他说，哎，其实做贡献没有那么难，然后去做了，但这样挺好的。我算吧。你也算吗？ Manjusaka: 对，我算。当时我是先认识张翔老师，然后后面然后跟他聊了一些，就包括我可能当时，那位你可能还认识，那个 Ezio Melotti。谁？18 年北京的那位嘉宾，Ezio。 laike9m: 你说 PyCon。 Manjusaka: 对，就是当时我们不是邀请到另外一位来北京。 laike9m: 哦。PyCon China Beijing 2018。2018 吗？2018 我去了吗？我有点不记得了。没事你继续说吧。 Manjusaka: 你在北京，你当时还没 transfer 去美国，然后你从上海来北京。 laike9m: OK。 Manjusaka: 然后我当时聊了一下，就后面开始，正好 18 年，后面我就说我正好在休息，后面就开始陆陆续续提一些贡献，对。 laike9m: 嗯，对对，其实我觉得翔哥一定程度上也是当时给了我一些激励或者指导嘛，对。 Manjusaka: 对，张翔老师还是非常 nice 的。 laike9m: 对，就给听众们如果有不知道，就是张翔是中国的第一个 CPython core developer, 第一个核心开发者，对，然后高天是第二个。 Manjusaka: 对，然后张翔老师应该是在 16 年晋升的。嗯，反正是老前辈了，老前辈了。 laike9m: 但其实他当时就是更多是因为工作中会需要改一些 CPython 代码，他当时在华为嘛，对吧？ Manjusaka: 然后。哦，不不不，他晋升成为 CPython Core 的时候，我记得没错，是在新浪，然后他就开始编的。 laike9m: 哦，新浪，OK。 Manjusaka: 对，然后他去华为其实做的也不是跟 CPython 本身相关的，他是去做的 OpenStack 相关的东西。对，然后他对就是说是整个生态工具链会比较熟，所以说他可能跟高天老师就是说是有一点不一样，是张翔老师对于各种非常疑难问题的 debug 非常擅长，这也是我记得介绍人给他在他的 promote 介绍里面说的，对。 laike9m: 嗯，我记得他当时那个演讲。 Manjusaka: 对对对，然后我的很多 debug 技巧也来自于张翔老师，对。 laike9m: Anyway，我觉得后人都是在前人的一些基础上去做工作的。 Manjusaka: 是的，没错。 laike9m: 好，那说回谭龙的这个 PR，我其实也简单看了一下，其实我原来也不知道补全要怎么加，但发现其实还真的挺简单的。你可以跟听众们大概说一下这个流程吗？比如说我要给一个像 Python 的 SQLite 命令行加补全，它大概要做些什么工作？ tanloong: 它是写一个 context manager，然后在你进那个 readline 的时候，你把 readline 的那个 completor 给替换成你自己的函数，然后在退出的时候再把它替换回你替换之前的那个函数，就你替换之前的那种 readline 的默认的 completor。然后你自己写的那个函数是还有一个 state, 就是 readline 调你的函数拿补全的时候，它会先给你发一个 state 等于 0, 这个时候你判断了 state 等于 0 的时候，你去生成一个完整的，就根据用户当前输入的那个 text, 生成一个完整的 completion candidate 的列表。然后 readline 会继续给你发 state 等于 1, 2, 3，这个时候你把你之前生成的 candidates 按照它发的 state 做个 index, 返回你的 candidates 对应的要补全的词。然后这中间就是 state=0 的时候，你的 candidates 最好需要缓存一下，不要在每次 readline 给你发 state=1, 2, 3 的时候你再重新生成，那样会比较耗时间，注意一下性能的问题。然后基本就是这样。 laike9m: OK，我说一下我看到的那个 PR 里面，我觉得比较关键的地方就是它其实就是一个首字母的匹配，就相当于首先你有一个关键词的列表，对吧？你要构建一个说哪些单词是 SQLite 关键词，比如说 SELECT 啊 JOIN 这种。然后我发现你是当用户每输入一个字符，然后你就会去跟这些关键词的前缀做一个匹配，对吧？然后发现如果有能 match 上的，你就把它作为一个 candidate 返回，作为补全的一个。 tanloong: 就其实那个关键字最开始的，你要拿到那个 SQLite 的完整的关键字的列表，当时对我来说还是挺难的。我最开始是从 SQLite 的文档里直接复制它的完整的所有的 147 个关键字，然后硬编码到 Python 里。但是有 core dev 说这样写不太好，而且其中有一个关键字并不是在所有的 SQLite 编译出来的时候都会支持的，是一个 V 开头的关键字。希望就是这个 SQLite 这个关键字能够动态生成。然后我当时查了一下，就是如果你想动态生成需要在 C level 去写，但是我这个 C 学的不太好，虽然之前学过一个学期的公开课，但是我完全不知道就是用我查到的 SQLite 文档里说生成关键字列表的那两个函数，去生产，我不知道要怎么写，然后我也不知道怎么把它放进 Python, 所以我当时说这个对我有点难。后来有一天晚上我看到那个消息里，那位 core dev 又说了一遍，就是非常希望这个关键字列表它是能从 C 里拿到的，而不是从 Python 里拿。我当时其实有点理解错了，我以为他的意思是让我把那个硬编码的关键字列表从 Python 给移到 C 里，然后我当时就把它移到 C 里了。虽然我对那个 Python 的 C 要怎么写，然后怎么把它暴露出来，暴露给 Python 的代码去能够访问，我用了一下 AI，当时是用的豆包，问怎么在 Python 的那个 C 里面存一个列表，然后能让它暴露出来，给 Python 的代码调用。然后当时豆包写上，然后我试了一下豆包给的结果，然后是可以的，然后我就直接硬编码到 C 里，然后问那个 core dev 行不行。但是 core dev 后来回复说他的意思是不是在 C 里硬编码，而是在 C 里要动态生成。当时我就，我感觉我理解错了。然后后来是另一位 core dev 帮忙给写的，然后他写了之后给发了一个 PR 到我的那个 fork 里，然后我合并进去，然后我的 fork 再合并到 CPython 的 main。 laike9m: 我还在想，就是因为我也看到你的那个 keywords 那部分是从 C 的 module 里 import 的。这个他当时说为什么要动态生成，其实我还是不太理解。可能就是 OK，我明白，但就是你编译的时候，你会根据你的 CPython 版本有不同的关键词，这样你就不用在那个 Python 里面写，比如说 if 是什么版本，然后你的关键字要加或者减一些东西是吧？ tanloong: 对的，SQLite 它应该是在编译的时候有一个选项，如果你开了某个选项，那么它的关键词会有变化。 laike9m: 明白明白。 tanloong: 哦。 laike9m: 这个确实还挺 tricky 的，对，感觉是这个 PR 里面最困难的部分。 tanloong: 确实。 Manjusaka: 嗯。 laike9m: 那所以就是总体这个流程下来你有什么感受吗？因为我知道你的那个 PR 还被因为把 test break 了还被 revert 了一次，对吧？ tanloong: 对，它是有一个测试在运行那个 run_pty 的时候，它是用那个 run_pty 生成一个 sudo terminal, 就在一个伪终端里去模拟用户的输入，然后查看它给的 candidates 是不是符合预期。但是在那个伪终端里，它给的 candidates 是带颜色的。就是你的 candidates，它的两边会有那个控制符。 laike9m: 它那个颜色码嘛，然后就不对了。 tanloong: 对，然后测试就 fail 了。当时是在那个 buildbot 上跑构建，就是构建失败，我找了一下，但是我想就是在那个 buildbot 上最好能有一个 interactive 的，就我能像在终端里我手动敲命令一样，我可以人为的去测试，然后看一下它中间到底是什么样子，再修改那个测试。但是 buildbot 我找不到我要怎么就进那个交互式的模式，也可能根本就没有。然后这个问题我解决不了。然后当时是有个 core dev 说他去找那个 buildbot 的 owner，然后问他要 SSH 的权限，然后他去调试。 laike9m: 等一下，我有一个疑问，就是为什么你这个 PR 感觉大家都很 helpful? 因为你知道一般的 CPython PR 就是你提了之后，可能很长时间都没有人理。这点你是怎么看的？就是感觉大家都会去帮你去 debug 或者帮你写些代码，这个是自然的吗？还是说他们本来就对这个很有兴趣还是怎么样？ Manjusaka: 嗯，从我的角度出发的话，我不太确定，高天老师那边可能有其他的 input, 但是就我观察来看，这个取决于 core dev 风格。不过他们整体来说，对新人是比较友好的。而且去 buildbot 里面调试这种东西的话，我觉得这个东西其实也还好，你去翻看 CPython 的 PR 其实这种事情也有不少，所以说我觉得这个相对来说还好。但是对于一些争议或者说是还在试图达成共识的过程中，那确实是比较头疼的。但是如果说是已经达成共识要去实施的一个 PR, 那我觉得相对来说会好一些。 laike9m: 明白，所以就是这种没有什么争议性的，只是实现或者一些 debug 问题就会推进的比较快，然后大家也会帮忙。 Manjusaka: 对，而且这种东西我理解主要是你添加新的 feature，而不是更改 API 的话，那这种东西就会好很多。就像我上周的时候，我当时想改 sys._enable_profile() 那个 API, 就是新增加的那个远程 debug 的接口，我想新增加在它的 audit event 里面增加一些元数据。这就牵扯到了 API 的更改以及更内部的一些细节上的更改。然后我就和三个 core dev，然后 Victor, Paul，还有哪一位，然后就 battle 了两天，然后最后 I gave up。 laike9m: 好吧，他们可能有一些 concern。 Manjusaka: 对，就这种你增加一些新的 API 之类的，就是会有一些比较 concern, 但是如果说你是实现一个全新的 feature, 大家觉得你这个 feature 不是为了实现而去实现，那这种情况下相对来说还是会比较顺利的。 laike9m: 嗯，嗯，理解。还有一点就是我知道那个 CPython 的不同模块，它其实是不同的人来维护的嘛。 Manjusaka: 啊，是的，没错。 laike9m: 就可能恰好就是 SQLite 这个维护者，他就是比较积极，比较热心，就是反应比较快，所以。 Manjusaka: 啊，是的，没错。它是比较活跃的，就是 SQLite 这种东西。我就又说到一个伤心事。在改一个东西，然后被 Mark 直接给拒了，然后我现在都还推不动，虽然大家都说有需求，但是 Mark 就觉得说这个东西没需求，然后但是就给拒了，对。 laike9m: 我知道 Mark Shannon 这个人比较固执，对，也是跟人的性格有很大关系。 Manjusaka: 对，是的，没错，跟这个看具体的开发者的问题，对。 laike9m: 对，就是其实你会发现像 Python，如果你不了解，可能会觉得 Python 是一个有一个很庞大团队去维护的这么一个精密复杂的系统，但你真正去看它里面到底是怎么实现的，或者说去提 PR 才会发现可能每一个文件它就是那么一两个人懂，然后你就是要找那一两个 stakeholder, 如果你想做一些更改的话，然后你只要能比如说说服他们，然后你就可以做你想做的。对，它相当的扁平吧。 Manjusaka: 对，我觉得主要还是怎么说服。 laike9m: OK，所以说回谭龙你这个 PR 的话，然后就你把那个 core developer 帮你把测试修好了，对吧？然后你就重新提交，这样子。 tanloong: 对的。就我感觉给 CPython 这个维护者，在这些维护者之间就是它是有一个小圈子的，然后你作为一个新人去给他们交 PR 也是一个交际的过程。就是你要积极主动一点，然后就一般新人你第一次交 PR 的时候，比较容易会被带着审视的态度去看你的工作。然后你交 PR 的时候，你最好是把你之前想到的一些可能会拒绝你 PR 的理由给解释清楚，然后你为什么这样做，然后让他们就是在他们提出问题之前就看到你的解释，这样会就是更容易沟通，然后更容易让你的 PR 更顺利一点。 Manjusaka: 嗯，对。 laike9m: 我看到你其实你之前提了一个 issue 对吧，就是你说你希望能够在 SQLite 的命令行里支持这些补全。所以你提那个 issue 的时候当时就想说自己去实现这个吗？还是说你本来期待说其他人可以去做这个？ tanloong: 是的，我是准备自己实现的。因为 Python 的 dev guide 里面写，如果你想交一个 PR，你应该先写一个 issue, 除非你交的 PR 是 typo fix。所以我就是先写的那个 issue，然后就紧接着交了 PR。当然那个 issue 题目写得有点大了，我那个 PR 只做了关键字的补全，但是 issue 是所有的补全。比如说你以后也许还会需要补全你的那个 SQLite 里面的表名，还有列名，还有函数名，这些目前还不支持。 Manjusaka: 明白。 laike9m: 所以你未来打算就是继续在这方面做一些事情吗？还是说就先到此为止？ tanloong: 也许会吧。但是这个刚才说的表名、列名、函数名，我目前还没有想到就是要怎么才能实现它。我看到就是 Python 的 PyPI 上有一个第三方的 SQLite 的命令行是支持表名、列名、函数名的，而且它是 context-sensitive，就是它会检测你当前是不是需要输入一个表名或者列名，比如说你是在 SELECT 后面，那它就会给你补全列名。就像这种就是非常智能的补全，我还没有想到就是怎么在 CPython 里支持，也许没有那个能力去支持它，总之就是还不确定。 laike9m: 明白。对，那个可能要就是回溯一下，不光得去做一个前缀匹配，对，会更复杂一点感觉。但我觉得是一个好的开始吧，就是你有一个这种框架，就会有更多人去加更多的 feature 进去。也许未来就会有。 tanloong: 是的，确实。就那个关键字的 PR 合进去之后，过了几天，有另一位 contributor 交了一个 dot commands completion 的 PR, 现在给加了那个 dot commands 的补全。目前 Python 的 SQLite 的命令行就有三个 dot commands，就是 .help, .version, .exit。.exit 还是 .quit 就来着，总之是推出的那个 .command。然后那个 PR 现在正是就是刚刚建不久，然后还没有 core dev 留言，但是它实现的有一点简单，就是有一些问题，但是应该后面会就是慢慢给修上，然后给合进去。 laike9m: 其实你可以去那个 review，因为你比较熟，你是最熟的其实。 tanloong: 是，我还真给看了一下，然后写了两个评论。但是写的第一个评论就是那位交 PR 的人，他觉得没有必要，就是他持反对意见。然后第二个评论，那位交 PR 的人还没有回复，然后其他人也没有回复。 laike9m: 嗯，我觉得挺好，就是因为我知道就是如果你比如说在一些 issue 里面回复的比较多，然后就会被那个提拔成 triager 的权限，对吧？然后其实这个是 core dev 之前的一步。 tanloong: 对，确实。然后我看就是交那个 dot command completion PR 的那个人，他的评论比较多，一般 CPython 有什么新的 issue，他都会先跑到底下去评论，然后有时候评论这个 issue 和之前的某个 issue 有联系。就像这种之类的，或者有人交 PR，然后他会去给 review。但是我还没有太多追踪 CPython 的那些 issue 和 PR，然后没有评论多少，就主要是我自己参与的那些 issue 跟 PR。 laike9m: 对，我觉得每个人有不同的风格吧，也不用一定去迫使自己要怎么样之类的。像高天那种，就是从 PDB 模块开始，然后把 PDB 弄得特别熟，然后通过成为 PDB 的维护者，然后来成为 core dev，这个路径也挺好的。我觉得可能更实际一点吧，因为我觉得你要去就是对于一些每一个 change 做一些评论，这个还挺难的。 tanloong: 确实从一个单独的模块开始做，你确实你的那个在 CPython 社区里面的成长会更容易一点。因为你是这个模块的专家，然后别人有什么问题就只能来找你。但是我也觉得这个也挺难的。天哥是从一个完全的 CPython 的陌生人，然后进入到 CPython 一点点做贡献，最后成为 core dev。就像你从一个外人进一家公司，然后慢慢走到管理层，都是非常难的步骤，你要获得信任，然后你做的每一个工作你都要给解释清楚，然后让别人就是认为你是可以承担更重要的角色。我觉得这也是非常难的一个过程。 laike9m: 嗯，是的是的。对，其实说回来就是那个，像给 CPython 做贡献不光是一个技术面上的事情，它还有很多这种交流，对吧？然后尤其是当你和这些外国人交流，你不是用你的母语，然后他们的一些交流的习惯可能也不太一样，所以这个方面也会有一些壁垒吧？就是谭龙，因为你是英文专业，所以这方面你觉得说你的本科教育有帮到你吗？ tanloong: 我觉得是有的。如果我没有选英语专业，我应该还停留在高中的那个状态，就是虽然当时英文成绩还可以，但是如果让我看一个全英文的网站，我是心里发怵的，我是心里有那个牴触的心理。但是大学接触英语比较多，然后主要是你抵触心理没有了，然后你愿意去哪怕接受自己写出来的英语没有那么完美，哪怕也不像母语，也不够 native-like, 你也可以接受自己写出来的这些句子，然后去交流。因为你只要能把意思给表达清楚，让对方看懂就可以。其实你放下这个心理负担，你会发现写英语还是没有那么难的。 laike9m: 是的，是的，同意，对。 Manjusaka: 我现在是有一个做简单的 workflow, 然后我会交给 AI 来帮我润色，然后扩展一下我单纯的观点。对，我觉得这是 AI 的一个很好的使用场景。 laike9m: 你用的是哪个工具呢？还是就是手动复制？ Manjusaka: 我是直接在 Claude AI 上面给他固定了一组 prompt。 laike9m: 明白，明白。 Manjusaka: 我觉得这就是这一块东西很好用的方式，特别是在我跟他们长篇大论地 battle 的时候，还是挺好用的。 laike9m: 帮我写一个回复去反驳这个人。 Manjusaka: 对，我一般是 prompt 就是说是我引用的那一段，然后我首先给他一个正面的肯定，然后其次列出我对他的观点，一 ABC，然后对，然后就这样。 laike9m: 你写 prompt 的时候是拿中文写吗？ Manjusaka: 我拿中文写。 laike9m: 嗯，OK，这样表意更准确一些。 Manjusaka: 对对对，你可以看我群里发的那个 issue，然后那个就是很多大段的，就是我是用 AI 生成出来的。 laike9m: 我想到之前在推特上看到一个段子，就是说在 AI coding 的时代，以前不都是什么 “Talk is cheap, show me the code” 吗？现在是 “Code is cheap, show me the talk”。 Manjusaka: 确实。Code is cheap, show me the talk. laike9m: 一个哥们他在他的 GitHub repo 里面就是把所有的他的那个跟 AI 的聊天记录全都传上去了。这个就是挺好玩的。 Manjusaka: 挺好玩的，挺好玩的。 laike9m: 对，像谭龙，我觉得你之前本来要在 C 模块里面写死 keyword 的时候，你也是用 AI 生成的，虽然后来发现那个路径是不对的，但是至少这方面 AI 的助力还是挺大的。 tanloong: 确实，如果我当时在紧接着问 AI 怎么不要硬编码，然后整个动态生成的话，也许我当时就能直接把动态生成的代码给交进去了，而不是让另一位 core dev 帮忙给写。嗯。 Manjusaka: 是的。 laike9m: 所以就是你对于这个给 CPython 第一次做贡献的这个流程，你有什么其他的一些感受吗？就是我们刚才还没有聊到的，你想分享的。 tanloong: 我没有了。 laike9m: 哦，行，那也没关系，好。我们也是觉得给 CPython 做贡献的人越多越好，然后可能也是能够给听众们一个激励吧。然后感觉这期其实录的挺快的，然后不知道有没有什么你想推荐的东西，就是如果你听我们之前节目的话，你应该知道有这个环节，对吧？ tanloong: 我推荐一个网站是跟量化金融有关的，算是一个给入门的学习者的一个索引吧。那个网站叫 QuantWiki。是量化金融中文百科，然后里面有一些就是量化金融相关的入门的概念，还有一些前沿的证券公司发的研究报告，还收录了其他的类似的 Python Data Training 这方面的 GitHub 的 repo 的链接。如果是这方面像我这样的刚入门的学习者的话，可以就是了解一下。 laike9m: 我看了一下，这个写的还挺好的，就是他把各种概念和一些工具都列出来了，对。嗯，我们之前也请过大伟来聊，就是他开发了一些交易相关的工具，所以其实这方面 Python 应用也是挺多的，对。 Manjusaka: 哎，反正我觉得给 Python 做贡献，就觉得还是希望像谭龙这样的人越来越多。是的，是的。对，而且现在他们就感觉是整体都非常缺人的感觉。 laike9m: 哪个看上去像不缺人？ Manjusaka: 嗯，这倒也是，确实。反正就之前我给 Brandon 和 Ken Jin 然后请教问题的时候他们都表示很新奇，我操居然还有 Freshman 对我们现在做的这块感兴趣。对，居然还有新人对我们感兴趣？Freshman，哦 Freshman。啊对，反正我觉得从他们视野来看，就整体的很多的地方都会很缺人。 laike9m: 嗯，是的是的，尤其是像你做的那些 debugging 啊，然后 tracing 的一些东西，我觉得懂的人真的很少。 Manjusaka: 我觉得就没人管的状态。而且就我现在对他们的 tracing 的部分有很大的怨言，就主要是 Mark 上面说... 哎，我后面会试着再推一推，但是就哎，随缘吧。 laike9m: 嗯，行。好的。Manjusaka 你有没有什么想推荐的东西。 Manjusaka: 我推荐一部番吧，《阳光马达棒球场！》，非常很不错的一部番，我推荐大家去看看。然后可能国内有很多朋友对于传统的国外的可能说足球或者其他也好，这种体育文化他并不清楚，这种体育文化到底应该是怎么样的，它是怎么样遍布在人的日常生活中的，然后有些人不清楚，那么我建议大家可以去看一下，然后挺治愈的一部番。 laike9m: 嗯，好的好的。啊，我先不推荐了吧，以后再说吧。对，我最近在看一些书，但是还没有看完，所以，对。好，其实我们这期是比较短的一期，然后但是也希望听众们可以从中学到一些东西，然后如果要记住一点的话，就是可能给 CPython 做贡献也没有那么难。对，好，我们这期就到此结束，然后各位听众我们就下期再见，大家拜拜。 众人: 拜拜。

Check out The Link.AI Consulting at https://agentic.constructionConnect with Hugh on LinkedinHere's a shorter briefing based on the same informationExecutive Summary:Anthropic's Model Context Protocol (MCP), announced in late November 2024, is an open protocol designed to standardize how AI systems interact with external data sources and tools. It aims to overcome the current fragmented landscape of AI integration, where bespoke solutions are often required for each new connection. MCP establishes a universal framework for communication, simplifying development, enhancing AI agent effectiveness through improved context and tool access, and fostering a vibrant ecosystem of AI capabilities. By utilizing a client-server architecture and defining key primitives for data and action exchange, MCP offers a more dynamic and context-aware approach compared to traditional REST APIs. The emergence of MCP registries and marketplaces like smithery.ai further signifies its potential to transform the future of AI by enabling more interconnected, adaptable, and powerful AI systems.Key Themes and Important Ideas/Facts:1. Addressing the Challenges of AI Integration:The current method of integrating AI models with external resources is often complex and requires custom solutions for each connection. "When building AI applications today, each project frequently requires unique, bespoke solutions for how AI processes are constructed and how they connect with necessary data resources." (Introduction)This leads to significant development and maintenance burdens.MCP aims to solve this by providing a universal, open standard for connecting AI systems with data sources and tools. "MCP offers a unified solution to this problem by providing a universal, open standard for connecting AI systems with data sources, effectively replacing these fragmented integrations with a single, consistent protocol." (Introduction)The motivation is to overcome the limitations of isolated AI models "trapped behind information silos and legacy systems." (Introduction, citing source 2)MCP addresses the "MxN problem" by transforming it into an "N plus M setup," where each model and tool only needs to conform to the standard once. "Without a standardized protocol, this results in a complex web of M multiplied by N individual integrations... MCP's approach transforms this into a much simpler N plus M setup, where each tool and each model only needs to conform to the MCP standard once..." (Introduction, citing source 3)By open-sourcing MCP, Anthropic intends to foster collaboration and a shared ecosystem.2. Core Concepts of MCP:Client-Server Architecture: MCP is built on this established pattern. "At its core, the Model Context Protocol (MCP) is built upon a client-server architecture, a well-established design pattern in computing, to facilitate the connection between AI models and external resources." (Core Concepts)Host: The AI-powered application or agent environment the user interacts with (e.g., Claude desktop app, IDE plugin). "The Host is the AI-powered application or agent environment that the end-user directly interacts with." (Core Concepts) It can connect to multiple MCP servers and manages client permissions.Client: An intermediary within the Host that manages the connection to a single MCP server, maintaining a one-to-one link. "The Client acts as an intermediary within the Host, responsible for managing the connection to a single MCP server." (Core Concepts) It handles communication lifecycle and maintains stateful sessions.Server: An external program that implements MCP and provides capabilities (tools, data, prompts) for a specific domain (e.g., databases, cloud services). "The Server is a program, typically external to the AI model itself, that implements the MCP standard and provides a specific set of capabilities." (Core Concepts) Anthropic and the community have released servers for Google Drive, Slack, GitHub, Postgres, SQLite, and web browsing.This architecture is likened to a "USB port" for AI. "This client-server architecture, often likened to a 'USB port' for AI applications, provides a standardized way for AI assistants to 'plug into' any data source or service without requiring custom code for each connection." (Core Concepts, citing source 3)3. MCP vs. REST APIs for AI Agents:Limitations of REST APIs: Require significant manual effort, lack standardized context management, often stateless, static API definitions. "Integrating AI agents with external services via REST APIs often requires significant manual effort and lacks a standardized way to manage the evolving context of agent interactions." (MCP vs. REST APIs for AI Agents)Advantages of MCP:Standardized Communication: Based on JSON-RPC, simplifying integration.Dynamic Tool Discovery: AI can query servers to understand available tools. "AI models equipped with an MCP client can query connected servers to understand the tools and resources they offer." (MCP vs. REST APIs for AI Agents)Two-Way Real-Time Interaction: Supports persistent connections for context updates.Superior Approach Scenarios: Complex workflows with multiple tools, real-time data integration, frequently changing toolsets, intelligent assistants, automated coding tools, dynamic data analytics.4. Enhancing AI Agent Effectiveness:Improved Contextual Awareness and Management: MCP allows agents to access and retain relevant context from multiple sources, overcoming context window limitations. "One of the most significant ways in which the Model Context Protocol enhances the effectiveness of AI agents is by enabling improved contextual awareness and management." (Enhancing AI Agent Effectiveness)The ability to connect to multiple servers simultaneously supports complex workflows.The "Resources" primitive provides just-in-time, modular context, leading to more efficient processing and accurate responses.Facilitating Seamless Integration: MCP eliminates the need for custom code for each new data source or tool. "By providing a standardized interface, MCP eliminates the need for developers to write custom code for each new data source or tool that an AI agent needs to interact with." (Enhancing AI Agent Effectiveness)Pre-built servers for popular systems (Google Drive, Slack, GitHub, databases) streamline integration.Supporting Advanced Reasoning and Decision-Making: The "Tools" primitive allows agents to invoke functions and access real-time data.The "Sampling" primitive enables complex, multi-step reasoning processes (with recommended human approval).Real-World Examples:Corporate chatbots querying multiple internal systems.AI-powered coding assistants (Sourcegraph Cody, Zed Editor) accessing codebases.Anthropic's Claude Desktop accessing local files. "By integrating MCP, Claude can securely access local files, applications, and services on the user's computer." (Enhancing AI Agent Effectiveness)AI2SQL generating SQL from natural language.Apify allowing AI agents to access Apify Actors for automation.5. Driving Adoption for AI Tool Providers:Standardized Integration: Reduces the complexity and costs of developing and maintaining multiple custom integrations. "By providing a single, open standard for connecting AI models with tools, MCP reduces the need for tool providers to develop and maintain multiple custom integrations tailored to different AI platforms." (Driving Adoption for AI Tool Providers)Increased Interoperability: Tools can work with any MCP-compatible AI model, broadening the potential user base and reducing vendor lock-in. "Tools built using the MCP standard can seamlessly work with any AI model that has implemented an MCP client, regardless of the AI provider (e.g., Anthropic, OpenAI) or whether it's an open-source model." (Driving Adoption for AI Tool Providers)Opportunities for Innovation and Specialization: Enables developers to create specialized servers that can be accessed by any MCP client, fostering a division of labor.Benefits for Scalability and Future-Proofing: Ensures integrations remain compatible with future AI models adhering to the standard.6. Real-World Use Cases and Examples of MCP Implementation (Detailed):Coding Assistants: Sourcegraph Cody and Zed Editor.Enterprise Integrations: Block and Apollo. "Companies like Block and Apollo have adopted MCP to securely connect their AI systems with internal data repositories and customer relationship management (CRM) systems." (Real-World Use Cases and Examples of MCP Implementation)Desktop AI Applications: Anthropic's Claude Desktop.Data Querying Tools: AI2SQL.Automation Platforms: Apify.Community-Built Servers: Numerous servers on platforms like Smithery.ai and mcp-get.com for databases, cloud services, etc.7. Future Implications and the Evolving AI Ecosystem:Fostering Interoperability and Standardization: MCP has the potential to become a universal standard for AI integration. "By establishing a universal standard for AI integration, MCP could become the equivalent of HTTP for the web or USB-C for device connectivity in the AI world." (Future Implications and the Evolving AI Ecosystem)Could decouple AI model choice from underlying integrations.Potential Impact on AI R&D and Deployment: May shift focus towards effective utilization of external information over solely increasing model size. Could lead to more modular AI system designs.Addressing Potential Challenges: Requires buy-in from AI providers and tool developers. Security is paramount. Ensuring user trust and human oversight are crucial. "Security is another paramount concern. Allowing AI agents to access and interact with external systems, especially sensitive enterprise data, necessitates robust security measures to prevent unauthorized access or data leaks." (Future Implications and the Evolving AI Ecosystem)Conclusion:MCP offers a promising path towards a more interconnected, context-aware, and effective AI ecosystem. Its standardized framework addresses critical integration challenges, enhances AI agent capabilities, and provides new opportunities for tool providers and the broader AI community. While adoption challenges exist, the potential transformative impact of MCP on the future of AI is significant.

Stephen Margheim, a celebrated figure in the Ruby and Rails community, returns to unravel the fascinating intricacies of his latest project—writing a parser for SQLite's SQL dialect in Ruby. He shares his enlightening journey of translating complex SQL syntax, which at first seemed a simple endeavor but soon unfolded into a realm of deep learning and unexpected challenges. Alongside this, Stephen collaborates with Aaron Francis on "High Leverage Rails," a video course designed to spotlight the synergy between Rails and SQLite, offering a treasure trove of insights into developing high-quality applications.We dive into the nuanced world of SQL parsing, where Stephen candidly recounts the arduous process of porting SQLite's lexer and parser into Ruby. What began as a straightforward task quickly turned into a labyrinth of complex syntax and discrepancies that required astute attention and incremental progress. He reflects on the absence of a fully compatible SQLite parser in any language, emphasizing the significance of open parsers like Postgres in creating a robust ecosystem for tools and libraries.Stephen's excitement is palpable as he discusses Quickdraw, a groundbreaking testing framework that revolutionizes testing in multi-core environments. This innovation, along with the anticipation for RailsConf 2025 in Philadelphia, paints a bright future for the Rails community. With rich discussions on parsing, testing, and upcoming Rails events, this episode promises to inspire and engage both seasoned developers and newcomers to the Ruby and Rails landscape.

After spending a decade working for appsec vendors, Grant McKracken wanted to give something back. He saw a gap in the market for free or low-cost services for smaller organizations that have real appsec needs, but not a lot of means to pay for it. He founded DarkHorse, who offers VDPs and bug bounties to organizations of all sizes for free, or for as low of cost as possible. While not a non-profit, the company's goal is to make these services as cheap as possible to increase accessibility for smaller or more budget-constrained organizations. The company has also introduced the concept of "fractional pentesting", access to cyber talent when and how you need it, based on what you can afford. This implies services beyond just offensive security, something we'll dive deeper into in the interview. We don't see DarkHorse ever competing with the larger Bug Bounty platforms, but rather providing services to the organizations too small for the larger platforms to sell to. Microsoft delays Recall AGAIN, Project Zero uses an LLM to find a bugger underflow in SQLite, the scourge of infostealer malware, zero standing privileges is easy if you have unlimited time (but no one does), reverse engineering Nintendo's Alarmo and RedBox's... boxes.
