Hey Berkeley, here's a new site showing Berkeley police and fire department activity. I believe this is put together by our old Twitter buddy @scanberkeley.com (Not to be confused with a different site: Berkeley Scanner). A good use of LLMs. berkeleycrime.com

USA is playing the World Cup here in the SF Bay today, but it's such a non event here that many folks didn't even know it was happening. I only know because we were finishing up on a Zoom call at 4:58 & a colleague *in another state* mentioned it.

Citizen, the crime and emergency app, has a problem with alerts that are way too broad and unnecessary. Yesterday's alert: something about a world cup game.

Talking about electricity usage is like this: Them: "So what is a kilowatt-hour exactly?" Me: "Well imagine that you had a 100-watt bulb and you used it for 10 hours. That's 100 watts x 10 hours. One kilowatt-hour." Them: "Sure, but what's a kilowatt-hour?"

One oddity in the AI experience is the inconsistency in the experience. Gemini on my phone fails ~20% of the time, claiming it can't do something that is clearly within it's scope. Today, I tried to set an alarm. Two tries, back to back, two different answers.
