With Terminal User Interface (TUI) for everything fiesible, my XPS 14 now idles at no more than 3.6W (sometimes even below 3W) with the screen at 70% brightness. The battery is 70 Wh. … Today I finished another round of idle-tick surgery on my Rust TUI stack. The numbers:

  • ~198,000 idle wakeups per day eliminated across kastrup and tock.
  • ~41,800 redundant SQLite queries per day removed from tock.
  • Two poller threads converted from 1-second spin-checks to Condvar waits.
  • One main loop moved from a 2-second wake tick to 10 seconds.

😳

That’s an impressive idle consumption for a non-Mac machine. I get that this is unlikely to be the best setup for most people. However, this is a fantastic example of how LLMs are making software more personal than ever for those who care and are opinionated.
