Ever wondered why do Rust's Vec , etc. always grow their capacity in powers of 2?🤔 Not just tradition. When we double the size (2^n), we can compute the new index (x) using a fast bitwise AND: `x & (capacity - 1)` Instead of expensive x `%` capacity.⚡ #Rust #LowLevel

Hi, did you remember this Tweet in July 2024 ? Right, I'm doing a new 12-months challenge (from October 2024 to October 2025, InchaAllah). No, it's not an app, nothing like that. At the end I'll tell you what it was.

Spent more time than expected building the mental model before touching kernels.c. Worth it. The lab got easier once I could reason about what the hardware was actually doing: cache lines, write-allocate, working sets. Code followed naturally. #BuildInPublic #LowLevel #CLang
Spent more time than planned on groundwork. Went through SRAM/DRAM internals via @CoreDumpped and Branch Education videos. Useful, but probably deeper than needed right now. Going over Drepper’s memory paper - lwn.net/Articles/25212… #BuildInPublic #LowLevel

Blocking fixed rotate. 8×8 tiles keep the dst working set bounded in cache regardless of image size. CPE went from growing badly with N to nearly flat across all five sizes - 1.7 to 3.2 vs naive's 1.7 to 8.3. ~19x speedup over baseline. #LowLevel #CLang #BuildInPublic

Smooth was a different problem. Removed avg()- 4 hardcoded regions, no conditionals in the interior loop. ~99% pixels hit a tight branch-free path. CPE ~43→12, ~60x speedup. Autograder clean. #LowLevel #CLang #BuildInPublic

First real insight: loop unrolling alone does nothing for rotate. Measured 2x/4x/8x unroll - all flat. The bottleneck isn't loop overhead, it's strided dst writes causing a cache miss on every single pixel. #LowLevel #CLang #BuildInPublic

built a #lowlevel agent that uses antonlytics.com for recall and evolution, it builds tools just in time (when needed) and doesn't rely on any third-party tools. The more you use it, the more it builds and knows.
