Very happily just paid my 12th year subscription to Feedbin. Rock solid, never have to think about it, and has gotten some nice capabilities over the years, like the ability to subscribe to newsletters via email and have it pipe into the feed reader instead. Highly recommended.

This morning, @dfreeman.io and I were chatting about various tradeoffs in extension points for programming languages for e.g. UI—including an off-hand reference to @ltratt.bsky.social’s group’s 2010s work—and simultaneously typed roughly “I could totally see doing a C.S. Ph.D. focused on this.” 😂

Pretty sure v6.chriskrycho.com is going to end up shipping in 2026, not 2025 like I hoped… because I just hit the end of my rope with one particular thing and yeah, I’m shaving a yak I kept telling myself not to shave (details revealed later). But it’ll be a really fun learning experience! 😂

Congrats to Marco Arment and David Smith for the really lovely 10-year-run that was Under the Radar. It was always one of my favorite shows, and I’ll miss having it show up in Overcast every two weeks, but there’s a real goodness to ending something when its time has come. 🥂

I was 38 years old when I decided, inspired by a friend, that to the store of Scripture I have memorized (most of Hebrews and Ephesians still tumbling around l!), it was time to claim my inheritance and memorize some great English #poetry. I started with Emma Lazarus’ The New Colossus. Next: TBD!

Just another data point in the search engine space: I’ve been paying for @kagi.com for 6+ months and I am extremely happy with it. Even the limited applications of LLMs are done well, stay out of the way, and are totally disable-able. I *love* being able to reprioritize and even block whole domains.

We just showed our girls “Rose” (Doctor Who Series 1.1) for the first time. They agreed that 1.1 was pretty cheesily done and hard to follow audio-wise (the mix is atrocious!)… and also already think the Doctor is great. “I love that guy!” our 13-year-old kept repeating. 😂

The Case for Bringing Back Verse Plays
Though barely attempted today, plays written in verse were once quite common. J. C. Scharl's latest is a triumph for the genre and a joy to read.

15,066.6̅% is a pretty good new listener rate. 😂
Beginning to think that Spotify’s stats are maybe not that coherent. Something *literally* does not add up here. 😂 Whoops.
(Bugs like this happen, and with large enough audiences this particular bug probably gets lots in the noise—but not with mine!—, so it’s extra funny in this case.)
