step 1: do an experimental JIT step 2: do a website called https://www.doesjitgobrrr.com to track performance step 3: write a PEP called "JIT Go Brrr" step 4: non-experimental JIT gone brrr? step 5: CPython gone brr? step 6: brrr? https://peps.python.org/pep-0836/ #Python #CPython #JIT #PEP #PEP836 #JIT #GoBrrr

RE: https://code4lib.social/@acdha/116558806694701121 Do not use pull_request_target. Do not use caches in publish workflows. Use dependency cooldowns. Use Zizmor. Tell GitHub to make Actions secure by default. #GitHub #GitHubActions

RE: https://mastodon.social/@hugovk/116534312819614916 Just as importantly! After two years, it&#39;s now time to ceremoniously hand over the `main` branch to @savannah! `main` is now accepting new features for Python 3.16, and I bet it&#39;s going to be even better than 3.15. https://peps.python.org/pep-0826/ #Python #Python315 #Python316

Do you use astral-sh/setup-uv@v7 in #GitHubActions? And it&#39;s not hash-pinned? And you use #Dependabot or #Renovate? The setup-uv project has switched to only Vx.y.z tags, no more Vx or Vx.y. But Dependabot and Renovate won&#39;t upgrade from Vx to Vx.y.z, so you&#39;ll need to manually update to setup-uv@v8.0.0 to keep up with future updates. &quot;To increase security even more we will stop publishing minor tags. You won&#39;t be able to use v8 or v8.0 any longer.&...

Who would like Rust in CPython 3.15? @emmatyping and Kirill Podoprigora &quot;propose introducing the Rust programming language to CPython. Rust will initially only be allowed for writing optional extension modules, but eventually will become a required dependency of CPython and allowed to be used throughout the CPython code base.&quot; https://discuss.python.org/t/pre-pep-rust-for-cpython/104906 #Python #Python315 #CPython #Rust
