🕺 From #Python 3.13, virtual environments created by venv will come with a #Git ignore file, thanks to @brettcannon ’s PR merged yesterday. There’ll be no need to add .venv (or whatever) to your .gitignore file then..

FYI the virtualenv package already does this 😁

I just wrote this proposal that #Django’s third-party package tutorial recommend using a django_ module prefix to prevent name collisions, such as the historical one between django-ratelimit and ratelimit.

What do you think?

🏎️ Last night, I fixed a segmentation fault bug in my #Python testing library time-machine.

🤷 There were several outstanding issues about segmentation faults with unclear causes, and I didn’t have time to dive into them.

🐛 Then I received a new bug report from Marcin Sulikowski with a minimal reproduction. This research pointed directly at the problem and revealed the other reports as duplicates.

👏 Clear and reproducible bug reports are very valuable contributions!

#TodayInOpenSource

⏱️ After 6.5 years, pywatchman released a new version at the beginning of the month, including #Python 3.10+ support. Yay!

🦄 Django’s runserver can use pywatchman to drastically reduce the CPU cost of autoreloading. #Django gets pywatchman to send it file change notifications from the OS rather than polling every file every second.

✍️ In January, I removed the watchman section from Boost Your Django DX due to the incompatibility. But now I can restore it. 😊

♦️ There is a safer alternative to 'git push --force'!

🫸 Use --force-with-lease and --force-if-includes to restrict force pushes so that they don’t unintentionally overwrite commits pushed by others.

✍️ New post on improving diffs with the “histogram” algorithm

💡 Did you know that #Git generates diffs “on the fly” by comparing commit snapshots? And that there’s a superior built-in algorithm, “histogram”, that makes diffs easier to read?

👉 Learn about it in this new post, extracted from my Git book: https://adamj.eu/tech/2024/01/18/git-improve-diff-histogram/

Made a bunch of temporary files you don’t want to commit to #Git? Run git clean to erase them. -f is the non-prompting mode and -d removes untracked directories too.
