Michael #1: pyx - optimized backend for uv

• via John Hagen (thanks again)
• I’ll be interviewing Charlie in 9 days on Talk Python → Sign up (get notified) of the livestream here.
• Not a PyPI replacement, more of a middleware layer to make it better, faster, stronger.
• pyx is a paid service, with maybe a free option eventually.

Brian #2: Litestar is worth a look

• James Bennett
• Michael brought up Litestar in episode 444 when talking about rewriting TalkPython in Quart
• James brings up
  • scaling - Litestar is easy to split an app into multiple files
  • Not using pydantic - You can use pydantic with Litestar, but you don’t have to. Maybe attrs is right for you instead.
• Michael brought up
  • Litestar seems like a “more batteries included” option.
  • Somewhere between FastAPI and Django.

Brian #3: Django remake migrations

• Suggested by Bruno Alla on BlueSky
• In response to a migrations topic last week
• django-remake-migrations is a tool to help you with migrations and the docs do a great job of describing the problem way better than I did last week
• “The built-in squashmigrations command is great, but it only work on a single app at a time, which means that you need to run it for each app in your project. On a project with enough cross-apps dependencies, it can be tricky to run.”
• “This command aims at solving this problem, by recreating all the migration files in the whole project, from scratch, and mark them as applied by using the replaces attribute.”
• Also of note
  • The package was created with Copier
  • Michael brought up Copier in 2021 in episode 219
  • It has a nice .css-j9qmi7{display:-webkit-box;display:-webkit-flex;display:-ms-flexbox;display:flex;-webkit-flex-direction:row;-ms-flex-direction:row;flex-direction:row;font-weight:700;margin-bottom:1rem;margin-top:2.8rem;width:100%;-webkit-box-pack:start;-ms-flex-pack:start;-webkit-justify-content:start;justify-content:start;padding-left:5rem;}@media only screen and (max-width: 599px){.css-j9qmi7{padding-left:0;-webkit-box-pack:center;-ms-flex-pack:center;-webkit-justify-content:center;justify-content:center;}}.css-j9qmi7 svg{fill:#27292D;}.css-j9qmi7 .eagfbvw0{-webkit-align-items:center;-webkit-box-align:center;-ms-flex-align:center;align-items:center;color:#27292D;}
