  1. I vibed a proof of Conway's conjecture

    The author used Claude to generate a Lean formalisation and proof of Conway’s refinement conjecture for omnific (surreal) integers. The proof passes mechanical checks and informal review but lacks independent verification. The post narrates the workflow, token cost, and reflections on AI‑assisted theorem proving.

    Saving another 100TB of RAM with math (and Rust)

    Cloudflare reduced the memory footprint of its Pingora Backend Router by re‑examining the consistent‑hashing implementation in the pingora‑ketama library. By increasing the number of virtual hash points per server from the default 1 to the standard 160 (and applying weighted hashing based on disk capacity), they cut the per‑node overhead enough to reclaim >100 TB of RAM across the fleet.
