GHL has written two very nice Python-related posts. The first is for highly-technical readers who want to use the new Blaze package ("NumPy 2.0") so badly they'll do so even if it doesn't work yet -- and yes, I'm in that camp! Here are instructions for building Blaze. Note that due to its rapid development it's possible that these instructions will not work in the near future.
The second is a hands-on exploration of Python immutability, a concept that deeply frustrated me when I first learned about it because sometimes it doesn't seem to have any internal consistency.
