Heads up that I will be migrating this account to https://mastodon.social/@brettcannon shortly (assuming everything goes well). I believe the most visible thing that will happen is if I follow you I will show up as following you again from the new account. The impetus for this was […]

How did MCP get standardized before a location for prompt files? I'm rather dumbfounded that I can't write a single prompt file for a repo and just have the models all pick it up automatically without some editor-specific setting.

The PSF Developers-in-Residence program makes this possible, check out how the @ThePSF supports the Python ecosystem with full-time staffing: https://www.python.org/psf/developersinresidence/

Thanks to the work of Python Release Managers and all the Developers-in-Residence we have a coordinated #python #security release of all versions for 5 CVEs all in one day (1 critical, 3 high, 1 medium) […]

Perl: 37 years old Python: 34 years old

dependency groups 🥰

AI failed: paragraph-formatted spec using something introduced in Python 3.12 (Claude Sonnet 3.7 came the closest to succeeding; Claude 4 wasn't out yet) AI nailed: updating a Dockerfile so that it downloaded the right file for the CPU architecture (I told it the final outcome and to update CI […]

I'm looking for a functions-as-a-service with a cron/schedule trigger. I have found some, but I'm wondering if I'm missing any (I'll take any that can run Python, Rust, JS via ReScript or Gleam, or BEAM via Gleam)? […]

I was poking around the Mastodon APIs and I can't find a way to have a bot hide individual posts for me, only update my filters list. Am I missing something?

Went through various Pocket replacements this weekend. I wanted a read queue that has strips out superfluous stuff from the page (i.e. not bookmarking, so that eliminated Raindrop, Linkwarden). I tried: - Readwise: nice, but too expensive just for this and RSS not powerful enough to unseat […]

I want a mobile OS where apps are nothing more than PWAs or WebAssembly with worlds standardized by the Bytecode Alliance.

I just got the "Admired" badge on discuss.python.org, and I'm only the 2nd person after @pfmoore to get it. https://discuss.python.org/badges/31/admired I don't know what that says about Paul and me that we have posted over 300 times, let alone that many times with at least at least 5 likes. 😅

Just booked everything for #europython2025 ! I will be there Tuesday - Friday, so I will be at the #webassembly summit, my keynote, and everything else in the main conference! I will be staying with what seems like the rest of the conference in the Grand Hotel Prague Towers Monday through […]

Once again, if your LLM system combines access to private data, exposure to malicious instructions and the ability to exfiltrate information (through tool use or through rendering links and images) you have a nasty security hole This time, GitLab […]

If I had a connection in Munich from Canada to Prague and I had 1h45m to make that connection (so I suspect customs and security), is that enough time? It would be on Lufthansa the whole way if that helps. Otherwise I'm looking at 1h10m in Zurich (seems too short), 1h47m in Toronto (which is a […]

Mozilla is shutting down Pocket. https://getpocket.com/farewell Where to next? @instapaper ?

@pauleveritt I just started to listening to the Talk Python to Me episode on t-strings, and I can tell you that according to https://opensource.snarky.ca/About+Me/Appearances , @mkennedy has not found me interesting enough to be on since Dec 2023, so I have 3.5 years left to be boring 😉

The trailer for the Python documentary is out! https://youtu.be/pqBqdNIPrbo?si=9LLlghqZkJRAcnpF

I wrote a blog post unravelling t-strings to help explain what they are doing -- providing syntactic access to the f-string parser -- while we wait on the official docs. https://snarky.ca/unravelling-t-strings/ /cc @pauleveritt @lysnikolaou

There were layoffs at MS yesterday and 3 #python core devs from the Faster CPython team were caught in them. If you know of any jobs, please send them their way (they kind of know Python, CPython, and its internals well 😉): Eric Snow: https://www.linkedin.com/in/ericsnowcurrently/ Irit Katriel: […]

If you open an issue and use "GPT" as a verb then I'm going to assume your solution is wrong. Not because using AI is inherently bad, but because I'm going to assume you don't understand the problem or solution and you just "prompted" the problem away.

Someone didn't vibe code the tests?

@mkennedy thought you might find this interesting about the Zen browser. https://sizeof.cat/post/web-browser-telemetry-2025-edition/#zen-browser

The spec for pylock.toml is up! https://packaging.python.org/en/latest/specifications/pylock-toml/

Would having a short domain act as a link tree and URL shortener for myself be worth it in this day and age? Is having some domain.tld/github redirect to my GitHub profile as a URL to verbally tell people, have on slides, etc. worth it? (I know asking to be talked out getting yet another domain […]

Oops I did it again, I wrote a new PEP, got lost in the comments, oh coder, coder. Oops, you thought I could stop, that I knew better, I'm not that intelligent. https://discuss.python.org/t/pre-pep-import-name-metadata/90506 https://genius.com/Britney-spears-oops-i-did-it-again-lyrics

I thought I posted about the latest tool support for `pylock.toml`, but I can't find anything. So, there is now some form of support in: 1. UV 2. Pip 3. PDM 4. Pip-audit

I posted the same thing on both Bluesky and Mastodon where I have 3,578 and 3,404 followers, respectively. The posts were done Apr 28 in the afternoon. The engagement levels were (Bluesky vs. Mastodon): - 1 vs. 0 comments - 2 vs. 0 reshares - 15 vs. 8 likes/favourites

My review of @feedbin after my 1 month free evaluation: it's good and I would consider leaving @Inoreader for it if (1) it has a "mark as you scroll past" feature, and (2) I got a reply to my emails sent to their support address. Otherwise it has a clean web UI on both desktop and mobile and the […]

I think I might write a blog post about how Python determines what arguments to a function get bound to what parameter name (hint: it's all via `__code__` and can be reversed-engineered via locals in a stack frame).

If I'm going to prefer Mastodon over Bluesky I need to: 1. Find a good host to run my own instance (otherwise the federation benefits don't seem quite so beneficial); recommendations welcome as I don't have the time to self-host 2. File a feature request to make it easy to take your filters […]

Is there an Android app that will scan my installed apps list and tell me there's actually a web app I could be using instead?

I'm about to go to bed before I set up for a #python event that celebrates the joy of technology and the responsibility we have to use the skills we have to improve the world. A while ago, I caught the news that former #Python release manager, @swearyanthony is in the ICU in a critical […]

Thinking about print debugging and ways to specify what you want logged is giving me aspect-oriented programming flashbacks.

Uv has a PR open to add pylock.toml support! https://github.com/astral-sh/uv/pull/12992

Thanks to @sbidoul , pip 25.1 will have a `pip lock` command that uses `pylock.toml`! https://github.com/pypa/pip/pull/13213 pip-tools has started looking at if they can leverage it. https://github.com/jazzband/pip-tools/issues/2124 pip-audit has support in 2.9.0 […]

@brianokken The latest Python Bytes episode hasn't shown up at @pythonbytes , but to answer your question about the purpose of `[packages.tool]`, it's to set tool-specific details for each package entry instead of making tools come up with their own way of mapping tool-specific data to each […]

t-strings are coming! https://peps.python.org/pep-0750/ https://discuss.python.org/t/pep750-template-strings-new-updates/71594/130

Anyone know of an amp for ceiling speakers that does multi-point Bluetooth? Our house came with https://www.arylic.com/products/a30-wireless-amplifier , but we can only connect one device at a time which is annoying when we want to use our Bluetooth turntable.

I apologize for my acting in this video. https://fosstodon.org/@ThePSF/114263169280378337

PEP 751 has been accepted! https://peps.python.org/pep-0751/ This means #python now has a lock file standard that can act as an export target for all 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 […]

Any of the other @Vivaldi users getting annoyed by the various opt-out stuff getting pushed in updates? Like the "share Vivaldi" button in the extensions section or the Proton VPN stuff (I use @mullvadnet already)? I already stopped sponsoring the project over this since I wanted to pay for a […]

I FINALLY asked for pronouncement on PEP 751 -- lock files for #python : https://peps.python.org/pep-0751/ It does contain what is, I believe, necessary to have multi-use lock files. If that gets to stay in (@pfmoore has said that at this point he will ask me to remove stuff instead of […]

This is absurdly great, but I haven't read a single blog post or news article about it. A fully open source, offline-first alternative to Notion that's a collab between the French and German governments because they want to host documentation securely and on their own terms. THIS is what Europe […]

Due to the actions of the US government towards Canada, I will not be attending #pycon US this year. https://snarky.ca/why-i-wont-be-attending-pycon-us-this-year/

I updated the lock file example in PEP 751 after updating my PoC: https://peps.python.org/pep-0751/#example The most exciting thing is the `packages.attestation-identities]]` table thanks to attrs (and so thanks to [@hynek for using Trusted Publishers). Hopefully [@yossarian and the other PEP […]
