Brian #2: CVE Foundation formed to take over CVE program from MITRE

Back story: CVE, global source of cybersecurity info, was hours from being cut by DHS
- The 25-year-old CVE program, an essential part of global cybersecurity, is cited in nearly any discussion or response to a computer security issue.
- CVE was at real risk of closure after its contract was set to expire on April 16.
- The nonprofit MITRE runs CVE on a contract with the DHS.
- A letter last Tuesday sent Tuesday by Yosry Barsoum, vice president of MITRE, gave notice of the potential halt to operations.
- Another possible victim of the current administration.
CVE Foundation Launched to Secure the Future of the CVE Program
- CVE Board members have spent the past year developing a strategy to transition CVE to a dedicated, non-profit foundation. The new CVE Foundation will focus solely on continuing the mission of delivering high-quality vulnerability identification and maintaining the integrity and availability of CVE data for defenders worldwide.
- Over the coming days, the Foundation will release more information about its structure, transition planning, and opportunities for involvement from the broader community.

Topics covered in this episode: Making PyPI’s test suite 81% faster People aren’t talking enough about how most of OpenAI’s tech stack runs on Python PyCon Talks on YouTube Optimizing Python Import Performance Extras Joke Watch on YouTube About the show Sponsored by Digital Ocean: pythonbytes.fm/digitalocean-gen-ai Use code DO4BYTES and get $200 in free credit Connect with the hosts Michael: @mkennedy@fosstodon.org / @mkennedy.codes (bsky) Brian: @brianokken@fosstodon.org / @brianokken.bsky.social Show: @pythonbytes@fosstodon.org / @pythonbytes.fm (bsky) Join us on YouTube at pythonbytes.fm/live to be part of the audience. Usually Monday at 10am PT. Older video versions available there too. Finally, if you want an artisanal, hand-crafted digest of every week of the show notes in email form? Add your name and email to our friends of the show list , we'll never share it. Brian #1: Making PyPI’s test suite 81% faster Alexis Challande The PyPI backend is a project called Warehouse It’s tested with pytest, and it’s a large project, thousands of tests. Steps for speedup Parallelizing test execution with pytest-xdist 67% time reduction --numprocesses=auto allows for using all cores DB isolation - cool example of how to config postgress to give each test worker it’s on db They used pytest-sugar to help with visualization, as xdist defaults to quite terse output Use Python 3.12’s sys.monitoring to speed up coverage instrumentation 53% time reduction Nice example of using COVERAGE_CORE=sysmon Optimize test discovery Always use testpaths Sped up collection time. 66% reduction (collection was 10% of time) Not a huge savings, but it’s 1 line of config Eliminate unnecessary imports Use python -X importtime Examine dependencies not used in testing. Their example: ddtrace A tool they use in production, but it also has a couple pytest plugins included Those plugins caused ddtrace to get imported Using -p:no ddtrace turns off the plugin bits Notes from Brian: I often get questions about if pytest is useful for large projects. Short answer: Yes! Longer answer: But you’ll probably want to speed it up I need to extend this article with a general purpose “speeding up pytest” post or series. -p:no can also be used to turn off any plugin, even builtin ones. Examples include nice to have developer focused pytest plugins that may not be necessary in CI CI reporting plugins that aren’t needed by devs running tests locally Michael #2: People aren’t talking enough about how most of OpenAI’s tech stack runs on Python Original article: Building, launching, and scaling ChatGPT Images Tech stack: The technology choices behind the product are surprisingly simple; dare I say, pragmatic! Python: most of the product’s code is written in this language. FastAPI : the Python framework used for building APIs quickly, using standard Python type hints. As the name suggests, FastAPI’s strength is that it takes less effort to create functional, production-ready APIs to be consumed by other services. C: for parts of the code that need to be highly optimized, the team uses the lower-level C programming language Temporal : used for asynchronous workflows and operations inside OpenAI. Temporal is a neat workflow solution that makes multi-step workflows reliable even when individual steps crash, without much effort by developers. It’s particularly useful for longer-running workflows like image generation at scale Michael #3: PyCon Talks on YouTube Some talks that jumped out to me: Keynote by Cory Doctorow 503 days working full-time on FOSS: lessons learned Going From Notebooks to Scalable Systems And my Talk Python conversation around it. (edited episode pending) Unlearning SQL The Most Bizarre Software Bugs in History The PyArrow revolution in Pandas And my Talk Python episode about it. What they don't tell you about building a JIT compiler for CPython And my Talk Python conversation around it (edited episode pending) Design Pressure: The Invisible Hand That Shapes Your Code Marimo: A Notebook that "Compiles" Python for Reproducibility and Reusability And my Talk Python episode about it. GPU Programming in Pure Python And my Talk Python conversation around it (edited episode pending) Scaling the Mountain: A Framework for Tackling Large-Scale Tech Debt Brian #4: Optimizing Python Import Performance Mostly pay attention to #'s 1-3 This is related to speeding up a test suite, speeding up necessary imports. Finding what’s slow Use python -X importtime Ex: python -X importtime ptyest Techniques Lazy imports move slow-to-import imports into functions/methods Avoiding circular imports hopefully you’re doing that already Optimize __init__.py files Avoid unnecessary imports, heavy computations, complex logic Notes from Brian Some questions remain open for me Does module aliasing really help much? This applies to testing in a big way Test collection imports your test suite, so anything imported at the top level of a file gets imported at test collection time, even if you only are running a subset of tests using filtering like -x or -m or other filter methods. Run -X importtime on test collection. Move slow imports into fixtures, so they get imported when needed, but NOT at collection. See also: option -X in the standard docs Consider using import_profile Extras Brian: PEPs & Co. PEP is a ‘backronym”, an acronym where the words it stands for are filled in after the acronym is chosen. Barry Warsaw made this one up. There are a lot of “enhancement proposal” and “improvement proposal” acronyms now from other communities pythontest.com has a new theme More colorful. Neat search feature Now it’s excruciatingly obvious that I haven’t blogged regularly in a while I gotta get on that Code highlighting might need tweaked for dark mode Michael: git-bug Pyrefly follow up Joke: There is hope .…

Add your name and email to our friends of the show list , we'll never share it. Michael #1: git-flight-rules What are "flight rules"? A guide for astronauts (now, programmers using Git) about what to do when things go wrong. Flight Rules are the hard-earned body of knowledge recorded in manuals that list, step-by-step, what to do if X occurs, and why. Essentially, they are extremely detailed, scenario-specific standard operating procedures. [...] NASA has been capturing our missteps, disasters and solutions since the early 1960s, when Mercury-era ground teams first started gathering "lessons learned" into a compendium that now lists thousands of problematic situations, from engine failure to busted hatch handles to computer glitches, and their solutions. Steps for common operations and actions I want to start a local repository What did I just commit? I want to discard specific unstaged changes Restore a deleted file Brian #2: Uravelling t-strings Brett Cannon Article walks through Evaluating the Python expression Applying specified conversions Applying format specs Using an Interpolation class to hold details of replacement fields Using Template class to hold parsed data Plus, you don’t have to have Python 3.14.0b1 to try this out. The end result is very close to an example used in PEP 750 , which you do need 3.14.0b1 to try out. See also: I’ve written a pytest version, Unravelling t-strings with pytest , if you want to run all the examples with one file. Michael #3: neohtop Blazing-fast system monitoring for your desktop Features Real-time process monitoring CPU and Memory usage tracking Beautiful, modern UI with dark/light themes Advanced process search and filtering Pin important processes Process management (kill processes) Sort by any column Auto-refresh system stats Brian #4: Introducing Pyrefly: A new type checker and IDE experience for Python From Facebook / Meta Another Python type checker written in Rust Built with IDE integration in mind from the beginning Principles Performance IDE first Inference (inferring types in untyped code) Open source I mistakenly tried this on the project I support with the most horrible abuses of the dynamic nature of Python, pytest-check .

Topics covered in this episode: pre-commit: install with uv PEP 773 : A Python Installation Manager for Windows (Accepted) Changes for Textual The Best Programmers I Know Extras Joke Watch on YouTube About the show Sponsored by NordLayer : pythonbytes.fm/nordlayer Connect with the hosts Michael: @mkennedy@fosstodon.org / @mkennedy.codes (bsky) Brian: @brianokken@fosstodon.org / @brianokken.bsky.social Show: @pythonbytes@fosstodon.org / @pythonbytes.fm (bsky) Join us on YouTube at pythonbytes.fm/live to be part of the audience. Usually Monday at 10am PT. Older video versions available there too. Finally, if you want an artisanal, hand-crafted digest of every week of the show notes in email form? Add your name and email to our friends of the show list , we'll never share it. Brian #1: pre-commit: install with uv Adam Johnson uv tool works great at keeping tools you use on lots of projects up to date quickly, why not use it for pre-commit. The extension of pre-commit-uv will use uv to create virtual environments and install packages fore pre-commit. This speeds up initial pre-commit cache creation. However, Adam is recommending this flavor of using pre-commit because it’s just plain easier to install pre-commit and dependencies than the official pre-commit install guide. Win-win. Side note: No Adam, I’m not going to pronounce uv “uhv”, I’ll stick with “you vee”, even Astral tells me I’m wrong Michael #2: PEP 773 : A Python Installation Manager for Windows (Accepted) via pycoders newsletter One manager to rule them all – PyManager. PEP 773 replaces all existing Windows installers (.exe “traditional” bundle, per-version Windows Store apps, and the separate py.exe launcher) with a single MSIX app called Python Install Manager (nick-named PyManager). PyManager should be mainstream by CPython 3.15, and the traditional installer disappears no earlier than 3.16 (≈ mid-2027). Simple, predictable commands. python → launches “the best” runtime already present or auto-installs the latest CPython if none is found. py → same launcher as today plus management sub-commands: py install, py uninstall, py list, py exec, py help. Optional python3 and python3.x aliases can be enabled by adding one extra PATH entry. Michael #3: Changes for Textual Bittersweet news: the business experiment ends, but the code lives on. Textual began as a hobby project layered on top of Rich, but it has grown into a mature, “makes-the-terminal-do-the-impossible” TUI framework with an active community and standout documentation. Despite Textual’s technical success, the team couldn’t pinpoint a single pain-point big enough to sustain a business model, so the company will wind down in the coming weeks . The projects themselves aren’t going anywhere : they’re stable, battle-tested, and will continue under the stewardship of the original author and the broader community. Brian #4: The Best Programmers I Know Matthias Endler “I have met a lot of developers in my life. Lately, I asked myself: “What does it take to be one of the best? What do they all have in common?”” The list Read the reference Know your tools really well Read the error message Break down problems Don’t be afraid to get your hands dirty Always help others Write Never stop learning Status doesn’t matter Build a reputation Have patience Never blame the computer Don’t be afraid to say “I don’t know” Don’t guess Keep it simple Each topic has a short discussion. So don’t just ready the bullet points, check out the article. Extras Brian: I had a great time in Munich last week. I a talk at a company event, met with tons of people, and had a great time. The best part was connecting with people from different divisions working on similar problems. I love the idea of internal conferences to get people to self organize by topic and meet people they wouldn’t otherwise, to share ideas. Also got started working on a second book on the plane trip back. Michael: Talk Python Clips (e.g. mullet ) Embrace your cloud firewall ( example ).

Add your name and email to our friends of the show list , we'll never share it. Brian #1: How to Write a Git Commit Message Chris Beams 7 rules of a great commit message Separate subject from body with a blank line Limit the subject line to 50 characters Capitalize the subject line Do not end the subject line with a period Use the imperative mood in the subject line Wrap the body at 72 characters Use the body to explain what and why vs. how Article also includes Why a good commit message matters Discussion about each of the 7 rules Cool hat tips to other articles on the subject “ Keep in mind: This has all been said before .” Each word is a different link. Michael #2: Caddy Web Server via Fredrik Mellström Like a more modern NGINX Caddy automatically obtains and renews TLS certificates for all your sites. Caddy's native configuration is a JSON document. Even localhost and internal IPs are served with TLS using the intermediate of a fully-automated, self-managed CA that is automatically installed into most local trust stores. Configure multiple Caddy instances with the same storage, and they will automatically coordinate certificate management as a fleet. Production-grade static file server. Brian #3: Some new PEPs approved PEP 770 – Improving measurability of Python packages with Software Bill-of-Materials Accepted for packaging Author: Seth Larson, Sponsor Brett Cannon “This PEP proposes using SBOM documents included in Python packages as a means to improve automated software measurability for Python packages.” PEP 750 – Template Strings Accepted for Python 3.14 Author: Jim Baker, Guido van Rossum, Paul Everitt, Kaudai Aono, Lysandros Nikolaou, Dave Peck “Templates provide developers with access to the string and its interpolated values before they are combined. This brings native flexible string processing to the Python language and enables safety checks, web templating, domain-specific languages, and more.” Michael #4: juv A toolkit for reproducible Jupyter notebooks, powered by uv . Create, manage, and run Jupyter notebooks with their dependencies Pin dependencies with PEP 723 - inline script metadata Launch ephemeral sessions for multiple front ends (e.g., JupyterLab, Notebook, NbClassic) Powered by uv for fast dependency management Use uvx to run jupyterlab with ephemeral virtual environments and tracked dependencies.

Topics covered in this episode: Git Town solves the problem that using the Git CLI correctly PEP 751 – A file format to record Python dependencies for installation reproducibility git-who and watchgha Share Python Scripts Like a Pro: uv and PEP 723 for Easy Deployment Extras Joke Watch on YouTube About the show Sponsored by Posit Package Manager : pythonbytes.fm/ppm Connect with the hosts Michael: @mkennedy@fosstodon.org / @mkennedy.codes (bsky) Brian: @brianokken@fosstodon.org / @brianokken.bsky.social Show: @pythonbytes@fosstodon.org / @pythonbytes.fm (bsky) Join us on YouTube at pythonbytes.fm/live to be part of the audience.

Add your name and email to our friends of the show list , we'll never share it. Michael #1: Git Town solves the problem that using the Git CLI correctly Git Town is a reusable implementation of Git workflows for common usage scenarios like contributing to a centralized code repository on platforms like GitHub, GitLab, or Gitea. Think of Git Town as your Bash scripts for Git, but fully engineered with rock-solid support for many use cases, edge cases, and error conditions. Keep using Git the way you do now, but with extra commands to create various branch types, keep them in sync, compress, review, and ship them efficiently. Basic workflow Commands to create, work on, and ship features. git town hack - create a new feature branch git town sync - update the current branch with all ongoing changes git town switch - switch between branches visually git town propose - propose to ship a branch git town ship - deliver a completed feature branch Additional workflow commands Commands to deal with edge cases. git town delete - delete a feature branch git town rename - rename a branch git town repo - view the Git repository in the browser Brian #2: PEP 751 – A file format to record Python dependencies for installation reproducibility Accepted From Brett Cannon “PEP 751 has been accepted! This means Python now has a lock file standard that can act as an export target for tools that can create some sort of lock file. And for some tools the format can act as their primary lock file format as well instead of some proprietary format.” File name: pylock.toml or at least something that starts with pylock and ends with .toml It’s exciting to see the start of a standardized lock file Michael #3: git-who and watchgha git-who is a command-line tool for answering that eternal question: Who wrote this code?! Unlike git blame, which can tell you who wrote a line of code, git-who tells you the people responsible for entire components or subsystems in a codebase. You can think of git-who sort of like git blame but for file trees rather than individual files. And watchgha - Live display of current GitHub action runs by Ned Batchelder Brian #4: Share Python Scripts Like a Pro: uv and PEP 723 for Easy Deployment Dave Johnson Nice full tutorial discussing single file Python scripts using uv with external dependencies Starting with a script with dependencies. Using uv add --script [HTML_REMOVED] [HTML_REMOVED] to add a /// script block to the top Using uv run Adding #!/usr/bin/env -S uv run --script shebang Even some Windows advice Extras Brian: April 1 pranks done well BREAKING: Guido van Rossum Returns as Python’s BDFL including Brett Cannon noted as “Famous Python Quotationist” Guido taking credit for “I came for the language but I stayed for the community” which was from Brett then Brett’s title of “Famous Python Quotationist” is crossed out. Barry Warsaw asking Guido about releasing Python 2.8 Barry is the FLUFL, “Friendly Language Uncle For Life “ Mariatta can’t get Guido to respond in chat until she addresses him as “my lord”. “… becoming one with whitespace.” “Indentation is Enlightenment” Upcoming new keyword: maybe Like “if” but more Pythonic as in Maybe: print("Python The Documentary - Coming This Summer!") I’m really hoping there is a documentary April 1 pranks done poorly Note: pytest-repeat works fine with Python 3.14, and never had any problems If you have to explain the joke, maybe it’s not funny. The explanation pi, an irrational number, as in it cannot be expressed by a ratio of two integers, starts with 3.14159 and then keeps going, and never repeats. Python 3.14 is in alpha and people could be testing with it for packages Test & Code is doing a series on pytest plugins pytest-repeat is a pytest plugin, and it happened to not have any tests for 3.14 yet. Now the “joke”. I pretended that I had tried pytest-repeat with Python 3.14 and it didn’t work. Test & Code: Python 3.14 won't repeat with pytest-repeat Thus, Python 3.14 won’t repeat. Also I mentioned that there was no “rational” explanation. And pi is an irrational number. Michael: pysqlscribe v0.5.0 has the “parse create scripts” feature I suggested! Markdown follow up Prettier to format Markdown via Hugo Been using mdformat on some upcoming projects including the almost done Talk Python in Production book . Command I like is mdformat --number --wrap no ./ uv tool install --with is indeed the pipx inject equivalent, but requires multiple --with's: pipx inject mdformat mdformat-gfm mdformat-frontmatter mdformat-footnote mdformat-gfm-alerts uv tool install mdformat --with mdformat-gfm --with mdformat-frontmatter --with mdformat-footnote --with mdformat-gfm-alerts uv follow up From James Falcon As a fellow uv enthusiast, I was still holding out for a use case that uv hasn't solved. However, after last week's episode, you guys finally convinced me to switch over fully, so I figured I'd explain the use case and how I'm working around uv's limitations. I maintain a python library supported across multiple python versions and occasionally need to deal with bugs specific to a python version. Because of that, I have multiple virtualenvs for one project. E.g., mylib38 (for python 3.8), mylib313 (for python 3.13), etc. I don't want a bunch of .venv directories littering my project dir. For this, pyenv was fantastic. You could create the venv with pyenv virtualenv 3.13.2 mylib313 , then either activate the venv with pyenv activate mylib313 and create a .python-version file containing mylib313 so I never had to manually activate the env I want to use by default on that project. uv doesn't have a great solution for this use case, but I switched to a workflow that works well enough for me: Define my own central location for venvs. For me that's ~/v Create venvs with something like uv venv --python 3.13 ~/v/mylib313 Add a simple function to my bashrc: ` workon() { source ~/v/$1/bin/activate } \ so now I can run \workon mylib313 or workon mylib38 when I need to work in a specific environment. uv's .python-version` support works much differently than pyenv's, and that lack of support is my biggest frustration with this approach, but I am willing to live without it. Do you Firefox but not Zen? You can now make pure Firefox more like Zen’s / Arc’s layout. Joke: So here it will stay See the follow up thread too! Also: Guido as Lord Python via Nick Muoh…

Add your name and email to our friends of the show list , we'll never share it. Brian #1: mdformat Suggested by Matthias Schöttle Last episode Michael covered blacken-docs, and I mentioned it’d be nice to have an autoformatter for text markdown. Matthias delivered with suggesting mdformat “Mdformat is an opinionated Markdown formatter that can be used to enforce a consistent style in Markdown files.” A python project that can be run on the command line. Uses a style guide I mostly agree with. I’m not a huge fan of numbered list items all being “1.”, but that can be turned off with --number, so I’m happy. Converts underlined headings to #, ##, etc. headings. Lots of other sane conventions. The numbering thing is also sane, I just think it also makes the raw markdown hard to read. Has a plugin system to format code blocks Michael #2: pre-commit-uv via Ben Falk Use uv to create virtual environments and install packages for pre-commit. Brian #3: PEP 758 and 781 PEP 758 – Allow except and except* expressions without parentheses accepted PEP 781 – Make TYPE_CHECKING a built-in constant draft status Also, PEP Index by Category kinda rocks Michael #4: Serie : rich git commit graph in your terminal, like magic While some users prefer to use Git via CLI, they often rely on a GUI or feature-rich TUI to view commit logs. Others may find git log --graph sufficient. Goals Provide a rich git log --graph experience in the terminal. Offer commit graph-centric browsing of Git repositories.

Add your name and email to our friends of the show list , we'll never share it. Michael #1: Why aren't you using uv ? Fun conversation on X by Armin Ronacher . Interesting quotes from the thread I get it replaces pip/pyenv, but should I also use it instead of the built in 'python -m venv .venv'? But I need python installed to make python programs? Because it places the venv in the project folder and I can't run executables from there due to corporate policy. Many such cases. No idea why astral doesn't address this with more urgency. Sounds like a bad corporate policy :) i’m too lazy to switch from pyenv and pip trust issues, what if they do a bait and switch … Because everyone said that about poetry and I'm not sure I'm really ready to get hurt again. Masochism Many times I tried a lot of similar tools and always come back to pip and pip-tools. Them are just work, why should I spend my time for something "cool" that will bring more problems? I tried this week but I was expecting a "uv install requests" instead of "uv add". Switched back to pipenv. we partially use it. will transition when Dependabot support is available. I’ll leave it with → Jared Scheel: Seeing a whole lotta Stockholm Syndrome in the replies to this question. Brian #2: Python Developer Tooling Handbook Tim Hopper “This is not a book about programming Python. Instead, the goal of this book is to help you understand the ecosystem of tools used to make Python development easier and more productive” Covers tools related to packaging, linting, formatting, and managing dependencies. Michael #3: Calling all doc writers: blacken-docs Run black on python code blocks in documentation files You can also install blacken-docs as a pre-commit hook. It supports Markdown, reStructuredText, and LaTex files. Additionally, you can run it on Python files to reformat Markdown and reStructuredText within docstrings. Brian #4: Reinventing notebooks as reusable Python programs marimo allows you to store notebooks as plaintext Python files properties Git-friendly: small code change => small diff easy for both humans and computers to read importable as a Python module, without executing notebook cells executable as a Python script editable with a text editor Also, … testing with pytest “Because marimo notebooks are just Python files, they are interoperable with other tools for Python — including pytest. “ “ Testing cells. Any cell named as test_* is automatically discoverable and testable by pytest. The same goes for any cell that contains only test_ functions and Test classes.” “Importantly, because cells are wrapped in functions, running pytest test_notebook.py doesn’t execute the entire notebook — just its tests.” Extras Brian: PyConUS announces Refund Policy for International Attendees New format now live for The Complete pytest Course Bundle and component courses Each course now available separately also pytest Primary Power is 13 lessons, 3.9 hours Using pytest with Projects , 10 lessons, 3.4 hours pytest Booster Rockets , 6 lessons, 1.3 hours of content New format is easier to navigate Better for people who like different speeds.

Michael: PyCon Taiwan is currently calling for proposals HN trends follow up via Shinjitsu I'm sure some other Hacker News reader has already given you the feedback, but in the unlikely case that they haven't, You read those headlines in this segment exactly wrong. “Ask HN: Who is hiring?" is a monthly post that asks employers to post about jobs they have available “Ask HN: Who wants to be hired?” is a monthly topic where they ask people who are looking for jobs to post about themselves in the hope that their skillset it is a good match (and not an LLM generated resume) So unfortunately your rosy analysis might need a less rosy interpretation.
