August 23, 2025: Weekly Notes 2025/10

  • Context switching is very hard. I feel it. And everyone seem to agree. Apparently, it takes roughly 23 minutes to recover after “hey, got one minute?” interruption. Surprisingly, there is very little in written literature to back this “23 mins” number https://news.ycombinator.com/item?id=44999373.
  • My car (Tata Nano XTA) refused to start a couple of weeks ago. I thought old battery but turns out broken rubber pipes, rusted and leaking metal pipes causing engine to go “cold”. Until a few years ago, Tata cars used to suffer from metal rusting, but according to r/carsindia, they are much better these days. Anyway the car spent a week in garage and I spent roughly 14,000 (Car Didn’t Start) to fix it. The car being out in the open is also making things worse. I don’t park it inside the building since rat chewed wires a couple of times.
  • I learnt about “Residuality Theory” in software architecture on GOTO Tech Podcast. I kind of like it. I did more digging and found Residuality Theory: A Rebellious Take on Building Systems That Actually Survive.
