Traveling keeps reminding me of how much work it is to: a) deal with impromptu to-do items (usually via email) b) keep everything charged Somehow we’re serfs to email and chargers, and nobody is setting shit on fire.

In a mad dash before my first proper vacation this year, here's pgbg 26.2 with the non-Postgres parts ripped out and imported from bgt. Architecturally, I'm very happy with both and hope y'all try to play around with it! github.com/hynek/pgbg/r...

Highlights These are some big changes but I think they're worth it: everything that does not depend on Postgres, has been moved into its sibling project bgt1 because they solve real problems and I'...

The ideal outcome would be if someone wrote something like mysqlbg or so on top of it. :D

Due to popular demand (it's me—I'm the demand), I've decided to cut pgbg in two and liberate the database-agnostic parts. So if you want a self-healing way to run a background thread in Python with flexible wakeups, check it out! bgt.hynek.me/stable/

Supervised background threads for Python: crash-only service loops, restarted with backoff, instrumented with structlog and Prometheus.

pgbg is a way to run fault-tolerant background threads with PostgreSQL-based¹ orchestration: lease-based leader election & NOTIFY dispatch. Hope you like it – it fell out of TWO other projects I want to open-source eventually. ¹ requires Psycopg, SQLAlchemy optional 2/2

When I was advocating for nogil/free-threading, I always said that it’s important not to judge threads by the APIs we have, but by the APIs we will build once they’re worth the trouble. Here’s my first contribution: github.com/hynek/pgbg 1/2

til `set -e` is “exit immediately” and `set -x` is “print commands before executing” For years I thought it’s vice versa and since I use them usually together there was never a reason to find out 😳

Happy/nervous to announce argon2-cffi-bindings, the low-level C binding wheels used by argon2-cffi. It's a big release w/ wheels for new platforms, but the biggest item is the liberation from setuptools w/ great help by Nathan Goldbaum & @henryiii.bsky.social! 🥳 #Python github.com/hynek/argon2...

To me, the biggest fall from grace re software quality is clearly Fantastical. I don't even want to put it on vibe coding because there were times of flakiness before, but oh boy is it barely usable nowadays. Guess it's time to get used to BusyCal.

between weird LinkedIn influencers urging to delete tests that never failed and Richard’s learnings I know on what team I want to be and whose software I want to use

a slide from Richard Hipp’s “Reliability Lessons From SQLite” talk enumerating:

What Richard Has Learned

• Testability must be a design objective
• 100% MC/DC testing works
• sizeof(tests_cases) >= 10*sizeof(code)
• Approx 10-20% of code used only for testing
• Clear, concise documentation
• Expect to spend most of your time testing
• Good version control - situational awareness

So excuse me if I call bullshit TODAY when one tries to make arguments based on measuring something that we agreed is immeasurable. The impact of LLMs is the most non-ergodic event of my lifetime and I find it wild when people think they can make general statements either way.

it's so baffling that Apple still hasn’t shipped a native version of Bartender, while constantly breaking all existing tools that provide that functionality

Month ago I would’ve said Ty but looks like Meta is putting more resources into Pyrefly. Also heard that Google might be embracing PF. Currently, the Ty LSP is better tho b/c it allows you to globally jump to methods while PF does only classes & funcs. But that might change. I’m obviously biased.

Happy to announce v3.0.0 of my build-and-inspect-python-package GitHub Action that does what the name says. If u maintain a Python pkg u should really give it a look! Much, much fewer broken pkgs have been pushed to PyPI & who doesn't love automatic trove classifier → GHA test matrix conversion‽

Good morning! Since it's become a drag to support in mainline, I've extracted svcs's Pyramid support into an own package svcs-pyramid. That means, the next svcs version will ship WITHOUT a `svcs.pyramid` module: github.com/hynek/svcs-p...
