Fix your tools
Last week I had to diagnose a bug in an open source library I maintain. The issue was gnarly enough that I couldn’t find it right away, but then I thought: if I set a breakpoint here and fire up the debugger, I will likely find the root cause very soon… and then proceed to mercilessly destroy it! So I rolled up my…

Don't create .gitkeep files, use .gitignore instead (2023)
Git only tracks files, not directories. It will only create a directory if it contains a tracked file. But sometimes you need to “track” a directory, to ensure it exists for fresh clones of a repository. For example, you might need an output directory called build.

Gwtar: A static efficient single-file HTML format
Gwtar is a new polyglot HTML archival format which provides a single, self-contained, HTML file which still can be efficiently lazy-loaded by a web browser. This is done by a header’s JavaScript making HTTP range requests. It is used on Gwern.net to serve large HTML archives.

I gave Claude access to my pen plotter
I gave Claude Code access to my pen plotter. Not directly. I was the interface between the two machines. Claude Code produced SVG files that I plotted with my pen plotter. With my smartphone I captured photos that I pasted into the Claude Code session, asking Claude what it thought about the pictures. In total, Claude…

Many people believed AI could already assist with programming—seemingly replacing programmers—but I never felt it brought any revolutionary change to the way I work. Sure…

Start all of your commands with a comma (2009)

Claude Code: connect to a local model when your quota runs out
If you’re on one of the cheaper Anthropic plans like me, it’s a pretty common scenario when you’re deep into Claude coding an idea, to hit a daily or weekly quota limit.
