Blog for developers

The developer posts are build logs more than tutorials. ToolsTray runs entirely in the browser, with WebAssembly doing the heavy lifting, and a lot of what I learned getting it there is not written down anywhere else. How to keep a static site installable and working offline. What it costs to run a real model in a worker. Why a lazy boundary can shrink one chunk and grow the first load.

They include the code, the measurements, and the things that did not work. I would rather publish the dead end I spent a day on than a clean narrative that skips it, because the dead end is usually the useful part.

There is also a practical strand: how to tell whether an online JWT decoder is quietly sending your token to a server, and what to check before pasting anything sensitive into a tool you did not write.
