Enthusiastic hacker. Startup veteran (Rill Data, Retool, Looker, Apptio). I like it when things "just work" but have been known to tweak bits and bytes to get things "just so".
Liked this post by Ahmad El-Alfy (via HNews thread) on URLs as state containers. Often neglected in app design but compelling to end users.
Not so easy to get right since not all state should be in URL, and weirdness can happen with permissions. Always worth it though.

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...

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?!

Seeing surges of discussion around a topic and working backwards to figure out what caused the spike is a fun past time
The 1am science spike is still a mystery though

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.

uv is one year old today. Hard to believe its only been a year. The growth, adoption, and impact surpassed my wildest expectations.
Happy birthday, uv! 🥳

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.

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.
