Autoresearch, Claude and Constrained Optimization

kept by eddie jul 03

An experiment using Claude Code to autonomously optimize a file compression algorithm over 10 iterations, achieving competitive results against standard tools by iterating on an LZSS-based approach.

Fable's judgement
The author learned to let Claude Code's Fable model use its own judgement to delegate coding tasks to lower-power models, improving efficiency and token usage.

Claude's Voice Mode Just Got Smarter
Anthropic updated Claude’s voice mode to use Sonnet/Opus models, add Gmail/Slack context, and improve language support, while noting its turn‑based design limits naturalness.

Fast and Hard Code
LLMs diminish the need to learn language specifics, letting developers choose languages like Rust and Zig for speed and size, and tackle complex low‑level projects without deep expertise.

I wrote a 70x faster SQL parser while barely looking at the code - PostHog
The author used AI agents to rewrite PostHog's SQL parser in Rust, achieving a 70x speedup (454x in production) via property-based testing and oracle-based development.

I rewrote PostHog's SQL parser, 70x faster, while barely looking at the code
PostHog's engineer used parallel Claude Code sessions to rewrite their SQL parser, achieving a 70x speedup by fuzzing against the old ANTLR-based parser as an oracle.
