Just finished up a two-month jury duty stint and I’m really realizing how much solo projects depend on inertia and motivation. You take a break and it takes ages to get back in the swing of things.

I see endless people dragging WNBA & NWSL teams for “losing money” (“the NBA is subsidizing the WNBA”, etc)… but the Yankees, Clippers, Mets, Everton, Barcelona, etc aren’t losing money… they’re “investing in the club”.
Just can’t *quite* put my finger on the difference here.

I built a calendar again! Sort of. This one is super tiny: take all the bunch of calendars you might have, and then spit out a single URL that you can share with others.

I think the funniest thing that best describes the iPhone 17 Pro is that Apple doesn't even let you compare it against the iPhone 16 Pro. It... would not look that impressive.

Generally, I think it’s a great thing to take some time off from work, so you stay fresh and like, be a human. But keep in mind if you’re taking an official leave or sabbatical, it’s a great time for the company to fire you. It happens allllll the time.

One of the dumbest things I've done for as far back as I can remember is to check the start of every commit sha1 and see how long the first number is. So commit `78867d` is a nice five-int sha.

i’m a huge proponent of being in the Flow, when you’re deep in programming and don’t have any distractions to get in between you and your code. that’s why i never interrupt my AI as it writes all my code

there's something about how AI never writes tests for its code unless i explicitly tell it to that makes me think damn, it really did become a human-level programmer
