- [The last four points](https://beny.one/the-last-four-points) (2026-08-08): A perfect Lighthouse score taught me very little about making the page fast, and a great deal about how fast is measured.
- [Three stacks](https://beny.one/three-stacks) (2026-07-25): What I actually use, and why the honest answer is three different answers. Each one is downstream of a single constraint I refused to give up.
- [Everything in the binary](https://beny.one/everything-in-the-binary) (2026-07-18): One rule, no network calls, and the code it forced. A transformer reimplemented in Go, quantized to fit, and proved correct against the original.
- [Everything except the bytes](https://beny.one/everything-except-the-bytes) (2026-06-12): Uploading forty gigabytes is not a bandwidth problem. It is a coordination problem, and the coordination is where all the bugs live.
- [Where the key lives](https://beny.one/where-the-key-lives) (2026-05-09): Encrypting a secret is the easy part. The harder question is what happens to the decrypted key afterwards, and how long you let it exist.
