AI Analysis

●●●BangerWizardryBig Brain

Hand-written kernel language hitting 76% of cuBLAS performance on a 2080 SUPER.

Strengths
  • •Achieves 74% of theoretical GPU peak — meaningful performance for a solo research project
  • •Tile-first language design maps naturally to distributed DAG compilation
  • •44-minute technical deep-dive with verifiable benchmarks and PTX output
Weaknesses
  • •Single-machine validation only — no multi-node cluster benchmarks yet
  • •Personal learning project, not production-ready for real workloads
Target Audience

GPU programmers, compiler engineers, ML infrastructure developers

I built yawdl a tiny language that compiles in the browser

The author actually implemented a browser-side compiler using an Ohm.js grammar so you can write UI { } and Script { } blocks in one .yawdl file and have routing/metadata handled without a server. It’s a clever, compact experiment that’s useful for personal sites and tinkering, but it’s still early and a bit brittle — not yet compelling enough to replace Svelte/ASTRO-style single-file workflows.
