Git 3.0's upcoming SHA-256 default will be a costly mistake

6 weeks of Claude Code
It is wild to think that it has been only a handful of weeks. Claude Code has considerably changed my relationship to writing and maintaining code at scale. I still write code at the same level of quality, but I feel like I have a new freedom of expression which is hard to fully articulate. Claude Code has decoupled…

Discord is not documentation
I'm going to be slightly contrarian and say that I like Discord. It's great to be able to get real-time help on a problem. And it is fun to see, again in real-time, what other people are working on and struggling with. In truth, Discord is no harder to sign up to than Slack, Matrix, Gitter, IRC, or whatever. And of…
