Enjoying messing around with Claude Code! It does say "you're absolutely right" a lot, though. Pretty sure I'd have been done with my little weekend project by now if I was "absolutely right" with every idea and prompt...

"You're absolutely right on all counts." Oh LLM sycophants, I may talk like it (it's a professional hazard in tech), but it really isn't true.

A bit inspired by @simonwillison.net 's stream of vibe-coded "low stakes" tools, was pleased with Claude's take on explaining composition effects. The ratio of a subset of unique counts to the total unique count falls the longer the time window. Which still boggles my mind. How can 7 x 29 = 6?!

Work has had me in JS world for years and recently Go. I’ll still fire up the occasional Python notebook to try out a technique or perform a quick task. Tried uv recently when I got a new machine, and was gearing up to review my Python setup. It’s sooooo much better. Good infra. Recommended.

I'm a massive Golden Girls fan, so I can think of no better leadership for my Adeptus Sororitas. I've been working through this concept for YEARS and I'm excited to finally have it accomplished. Shout out to @bssterrain for the amazing head sculpts. #warhammercommunity #warhammer40k #goldengirls

Had my first Zoom call of the year today - audio problems made me grateful I wasn't the main speaker! The culprit was app memory bloat. Since I don't have a 192GB Mac that won't be the real consumption by Acrobat, the memory thief could be something else altogether. But that caught my eye!

“the fintech grew organically, acquiring a similar business with thousands of customers” It’s a valid strategy - but that is called “growth by acquisition”, usually seen as the opposite of growing organically.
