Dependabot opened six pull requests against my wiki repo over the last two weeks.

The fix was one character.

The commit is titled feat(deps): consolidate dependency updates.

A couple weekends ago I shipped nine releases of libsql-search, from 0.3.0 up to 0.11.0.

There’s exactly one file in one of my wiki projects that’s a security control rather than a config file, and I hadn’t read it in months. pnpm 11 removed onlyBuiltDependencies along with four related settings and replaced all of them with a single allowBui…

I shipped a logging library with a LOG_LEVEL environment variable.

I went looking through the rate limiter on a docs search API this weekend and found a comment I’d written explaining exactly how to defeat the code directly underneath it.

If you run a vector database, you’ve probably got a startup check that compares your configured embedding dimension against the collection’s actual vector size.

Adding a nullable column, or a column with a default, is the textbook example of a safe migration.

My MCP server has a just mcp-install recipe that prints a claude mcp add ... command you paste into a terminal.

I wrote a comment months ago that asserted a security property.

In forty-six minutes one morning I opened three pull requests, and every one of them deleted a dependency.

I ran a benchmark that should have ended the argument.

This series started two weeks ago with the question of what a file actually is.

Every format in this series so far has been a way of writing a document down.

A PDF does not have a current version.

The GIF89a specification defines the signature, the color tables, the LZW encoder, the four interlacing passes, transparency, and the per-frame delay.

MP4’s boxes are exact about everything: every byte accounted for, every offset written down.

XML’s answer to structure was a schema language, a query language, and a namespace system.

Last post ended on a question.

JSON’s problem is that its specification is too small.

Markdown has too many specs.

CSV is simple but powerful.

Last post ended on a promise: a .docx is a ZIP file, and you already know how ZIP works.

Every format in this series so far reads front to back.
