My agent.md to improve LLM-assisted code quality
The first time I tried to use an LLM to speed up coding was in mid-2025. I was not impressed. I was working on libadbmdns back then, an mDNS implementation in Rust. The code produced would not even compile.

macOS needs its grid back
Two decades ago I had a better Mac desktop experience than I have today. I only had a single low res (by todays standards) screen, yet I felt like Hugh Jackman in Swordfish - deftly navigating more than nine displays without thinking, muscle and spatial memory working seamlessly together. TLDR; I built an app to…

Distributing Mac software is increasing my cortisol levels

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. If you want to keep going, you can connect to a local open source model instead of Anthropic. To monitor your current quota, type: /usage

4x faster network file sync with rclone (vs rsync) (2025)
For the past couple years, I have transported my 'working set' of video and project data to and from work on an external Thunderbolt NVMe SSD. But it's always been slow when I do the sync. In a typical day, I may generate a new project folder with 500-1000 individual files, and dozens of them may be 1-10 GB in size…

Conventional Commits encourages focus on the wrong things
You’ve almost certainly encountered Conventional Commits before. It may have reared its ugly head in the changelog of an open source project you’ve used. It may have been the enforced commit format for an open source project you contributed to. A lot of people swear by it. I swear at it. Even though it is used by a…

Git at any scale
Hosting Git repositories at scale is a nightmare. When Linus Torvalds designed the first version of the information manager from hell (that's actually the tagline for Git, look it up ), he had a very specific use case in mind: his own. He wanted to replace BitKeeper, the distributed version control system that was…
