I eventually learned that there's a 'correct way up' for USB A cables. The two small holes should be on top. Tragically not all power adapters get this right, even for name brands. My ability to get the cable right first time still isn't much better than 50%!

I'm adding uptime data to my personal LLM bot. Does this information belong in the system prompt? That was my initial plan, but I'm thinking that a tool would be better. Tools let me see information provenance ("queried the uptime tool"). There's also a small caching benefit.

After further playing with my LLM project, I'm surprised how hard it is to tune with system prompts. My agent kept saying "obviously" even though my prompt said "helpful, professional". Eventually I found that a "courteous" prompt gets "of course" which is better but not ideal.
