A model writes the change. A model reviews the change and says it looks good. The pull request now...

Why an agent's freshly written helper often duplicates an existing utility, and how silent forks drift into real bugs.

git commit, npx, apt, ssh, psql, terraform apply, gh auth login: each can stall an AI coding agent on a prompt. The flag or env var that stops each one.

A 6B design model peaked at 64.4 GiB on an A100 80GB. Its transparent PNGs depend on a line break, so verify the alpha channel yourself.

When you ask Claude Code to "make a 60-second horror reel", it will happily start writing components....

We replayed 45 findings from a careful human code review against automated rules. They caught 9. Here is what that taught us about which problems tools can own, and the toolkit we built around it.

Developers discover that Claude Code ignores custom instructions because they set them in the wrong layer. Learn the three ways to shape Claude Code behavior, what the system prompt actually controls, and which parts remain locked no matte…

If an AI writes your code, your tests are the only thing standing between "it compiles" and "it's...

Train a toy byte-pair encoder in TypeScript and print every merge. Then ask o200k_base why pretty JSON and long keys cost you more tokens.

Agents can retype a module in an afternoon. Joel Spolsky's rule against rewrites was about the bug fixes buried in old code. Pin those first.

Nobody changed the model. Nobody touched the prompt. Accuracy dropped anyway. This is the most...

A screenshot can show what you built. A screen recording can show how it works. But making a short,...

Both make a model answer faster. Only one changes what the model is. A cost-and-quality comparison for teams shipping latency-sensitive inference.

Long context is sold as a feature and paid for as a memory bill. A cost-first look at why KV cache compression beats simply adding windows.

I coded by hand for about three years. When a feature was done, I could close the file and still...

Twenty agent turns, zero commits, red tests. A Claude Code Stop hook snapshots each turn to refs/agent-turns/, then git bisect finds the turn that broke it.
