NEW from me: CO2 emissions in China have now been flat or falling for 18 months, the first time that energy demand growth at or above historical averages doesn't drive emissions up, thanks to the clean energy boom. 🧵👇

I have a fetish for van Emde Boas trees .. • O(log log u) everything (insert, delete, lookup, successor/predecessor) is absurdly fast in practice once u <= 2^64 • It’s basically the integer version of a perfect dynamic hash table with worst-case guarantees. • The recursive

Random UUIDs are killing your database performance You switched from integer IDs (1, 2, 3…) to UUIDs (a1b2-3c4d-…) for security or distributed generation. Then your database writes get slower, sometimes much slower. Here’s why: Index Fragmentation. Most database indexes

Utter awesomeness this week from Axiom: A lot of the attention around AIutomated math has been focused on solving discrete problems, but I've always been most excited about its potential for fundamental theory-building. And this week, Carina Hong, Ken Ono, et al.

After interviewing 12 AI researchers from OpenAI, Anthropic, and Google, I noticed they all use the same 10 prompts. Not the ones you see on X and LinkedIn. These are the prompts that actually ship products, publish papers, and break benchmarks. Here's what they told me ↓
