    GPT-3 has basically replaced Google for me for searching through humanity's collective memory. Example below. The Google result is reminiscent of AltaVista from c.a. 1998.

    These people are likely supposed to be of the Ahrensburg culture, about 9000 to 12000 years ago. As far as we know, they had dark skinned and blue eyes. The light skin and blonde hair characteristic didn’t evolve until the Bronze Age

    It’s a simple misunderstanding of the problem as presented. They just take “false positive rate” to mean “the portion of positives that are false” rather than “the portion of all tests that are falsely positive”

    Each footstep gives ~0.5 joules. Estimate 100,000 steps a day, about 14 Wh. Enough to run a 60 W bulb for 15 minutes.

    3yo was learning about primary colors, and therefore asked a creative question: “are there primary numbers?” Didn’t think I’d be teaching my 43 month old about primes, but here we are. She loved the lesson, and felt very proud of her question and satisfied by the explanation.

    Here's a crazy idea for technical interviews. Instead of whiteboard coding, 45-minute algorithms challenges, and brain-teasers, ask the candidate to bring some code they wrote. It can be anything. The interview is then just a code review.

    The Commodore 64 is now as old as the ENIAC was when the C64 came out.

    In high school my funk band travelled to Denmark from Iceland by playing small gigs and saving up the money we got for wearing T-shirts plastered with logos of various companies we asked for sponsorship. We just asked each one if they'd give us ~$100 and they said sure.

    The truly precious resource is not your time, but attention. Spending attention wisely improves the quality of your time. Conversely, time is worthless when you attention is scattered.

    This book: "If you're feeling frustrated, that means you're low on dopamine and you need a break! Also if you're feeling frustrated that means your brain is about to learn something new and you should keep going!" Well, which is it?
