They've been popular for a long time, but I'm currently catching up, so there's a lot of new things here for me. I think we generally all understand why imbalanced experts are bad; both from a learning perspective (experts don't improve if they don't get enough gradients) and a performance perspective (unbalanced routing means many GPUs idle). Recently I… ## [Emacs Security Profiles: A Proposal](https://juanjose.garciaripoll.com/blog/emacs-security-model/index.html) _2026-05-24 · Juanjo García-Ripoll's blog_ ## [25 Years of Attending Python Conferences](https://droettboom.com/blog/2026/05/10/25-years-of-attending-python-conferences/) _2026-05-10 · Michael Droettboom · Boom!

At its heart an API must solve five core problems, affectionately known as CRUD plus querying. Your API allows developers to create, retrieve, update, and delete information — queries being a special type of retrieve action. Compared to the complexity of queries, the main CRUD methods are often considered trivial. Are they, though?
