Back in 1987, Apple released an album called "The Apple Boogie" and handed it out at conferences. You can listen to it in all its glory here, including a weird parody of the Ghost Busters theme..

I have a pure Ruby implementation of Doom (to be released soon). You *can* play it, but it's really for benching Ruby implementations and JITs (ala Optcarrot). Initial results: Ruby 4.0.2 without YJIT: 73 fps Ruby 4.0.2 with YJIT: 207 fps TruffleRuby 34: 235 fps

I was asking Claude about what animal has the worst life, and this sentence out of context feels like peak horror: "he bites into her flank and his body literally dissolves into hers, losing his eyes, fins, and organs until he's just a pair of gonads attached to her bloodstream"

I'm looking through a SIMTEL CD from 1992. I see a (rare for then) open source C compiler called Small-C. I Google to see if anyone has ported it to modern systems. A dude made his latest commit to one an HOUR ago. What are the odds.

A question that flummoxes LLMs: "Does English have any words which are the name of the place where the same named product is purchased or consumed, akin to cafΓ© in French?" SOTA models give wrong answers like "bakery" and "bar", except for Gemini 3.1 Pro which got "takeaway" and "carvery".

Briefly caught the genealogy bug and found my most distant ancestor so far: James Waterhouse, born in 1318, in Lincolnshire (where I live now!) At 23 generations above me, though, I realised I have 8,388,608 such ancestors, so he's probably one of yours too!

Music recs are boring, but OK: WOLF ALICE. They remind me of Fleetwood Mac. All their songs are so different.

It's refreshing how many bands this decade are heavily influenced by the 70s-90s and not continuing with the milquetoast bullshit that ruled the 2010s.

Just shut down my final Heroku app. End of a 16 year (or thereabouts) run for me! Heroku solved deployment for a generation of developers, then sorta became something we drifted away from despite continuing to work pretty well (and this app was solid as a rock for years).
