Over the last few months I've taken a deep dive into LLMs, AI, and ML, mostly around using them to develop software, and I keep coming back to these three videos by Andrej Karpathy. They are easy to digest (even if they don't look like it) and should be watched in order.
I deal a lot with time and time zones in the software I develop, and thankfully most frameworks make it pretty easy to manage. The rule tends to be, convert and store everything in UTC, and display it in the user's time zone in the UI, and call it a day.
In my previous post I talked about deciding what you give a fuck about and what you don't give a fuck about. But sometimes you realize you give a fuck about too many things still and you're still overwhelmed by the number of “threads” going through your brain. I know I was.
