Fable in its first 200K tokens shattered the record Opus and I had been stuck at for days on Non-Attacking Queens 16x16 solves. -38% wall time, -37.6 % nodes. 14.6 seconds. It moved like a killer. bsky.app/profile/tavi...

I've been obsessed with coding fast adversarial game tree solvers this week. Warmed up on Othello and then wrote dozens of increasingly fast solvers for Non-Attacking Queens. Record 16x16 in 24sec. This needs to be verified but here is the first ever 18x18 board solve.

A post by my friend Steve about the expansion plans of Mount Seymour Resort. The ski hill operates almost entirely within a Provincial Park and it already places roadblocks for public access. The expansion effectively transfers park land to a private operator, locking out the public.

In the month since I posted this latency chart for my search engine project bsky.app/profile/tavi... I've managed to eek out another 57x speedup on the p99 -> 12µs. 450x faster than the original chart.

Been going "tiger style" with perf optimizations. 10x speedup between first image and second/third. Now p50@ 26µs p95@ 271µs p99@ 695µs :)
