An experimental log of research, iterative design, and the trade-offs that shape the work — written for engineers navigating the same path.https://runbykomal.com/https://runbykomal.com/posts/the-data-race-that-passed-every-test/https://runbykomal.com/posts/the-data-race-that-passed-every-test/A lock-free SPSC ring buffer returned the correct sum on every run while containing a data race. Then a benchmark with a 2x noise floor almost convinced me the race was worth keeping. The fix was measurement, not luck.Wed, 15 Jul 2026 00:00:00 GMThttps://runbykomal.com/posts/the-part-the-algorithm-doesnt-see/https://runbykomal.com/posts/the-part-the-algorithm-doesnt-see/An O(1) lock-free scheduler lost 4–5× throughput to false sharing: two threads fighting over one 64-byte CPU cache line. The fix was memory layout, not the algorithm.Wed, 01 Jul 2026 00:00:00 GMThttps://runbykomal.com/posts/ground-zero/https://runbykomal.com/posts/ground-zero/There's no clean starting point for a log like this, so here's an honest one.Tue, 30 Jun 2026 00:00:00 GMT
