I'm *so* excited to share that I am now officially a CPython Core Developer! 🥳
I wrote my first Python in 2012, and immediately fell in love with the language. I'm honored that I am a part of, and can give back to, such an amazing, welcoming community!

Decompression is up to 30% faster in CPython 3.15
This blog goes over a journey to find an optimization in some lower-level code in CPython that yields a speedup of 10-30% when decompressing more than 1MiB of data.

If you use Python, send a few dollars to the charity to keep it going. I’m pushing a dono on behalf of ScamGuard.

Feeling so much better only weeks later was a huge relief.
