- This week I decided to go nuclear on my bad YouTube habit. I installed a plugin called Tab Limiter that lets me limit youtube.com to one tab at a time. Clicking links that open in new tabs will now auto-close the tab. Why do this? I talked about it before but when I’m bored I...
- “Typing is not the bottleneck” – illustrated. If you’ve followed me for a while, you’ll know how often I say this – especially since the rise of AI-assisted coding. Here’s an example. This is a cumulative flow diagram from Jira for a real development team. It shows work only...

- On April 21st, the Bluesky team announced a new account verification system. In my opinion, one of the best bits about Bluesky was the ability to verify yourself using a domain name. This new system goes a step further, and I was curious about how it worked. This lead to me...
