Tried out Dia for a few days solid - still so many features of Arc that I can't easily live without (primarily syncing with my phone, and the floating windows)

Anyone have recommendations for good walking/running shoes?\

nope

Hold on to your butts!

folks i’ve discovered the best website: butt.holdings

pub fn try_map<F, R> ( self, f: F ) → <R as Try>: :Residual as Residual<[<R as Try>:: Output; N]>>:: TryType where source F: FnMut (T) →> R, R: Try, Try>: : Output; N]>, <R as Try>:: Residual: Residual< [<R as

Kinda wild that someone thought to themselves that they wanted this to exist in the world

Just talked with someone who’s personally paying for 10 $200/mo claude max plans to avoid hitting rate limits locally - absolutely wild

It really feels like OpenAI has a great offering - but they fall behind on a lot of the newer product integrations

Finally gave in and upgraded to the pro plan on Claude - using Claude Code at work and also wanting to experiment with MCP servers more was just too much of an incentive

Found out one of my friends uses Amazon Music, haven't been able to look at them the same since

Finding myself falling down the Lesswrong and Gwern rabbit holes right now

Flying back to Boston this morning, wrapping up our 2 week west coast trip. It was a blast!

Screenshot of an incorrect answer in the jsdate.wtf quiz, the question was: `new Date("maybe 1")` and the correct answer was `2001-04-30T23:00:00.000Z` but I responded with `2001-05-01T00:00:00.000Z`.

Darn - the only one I missed on the quiz and it was because I forgot that the answers were based on another timezone 🤦‍♂️

Check out the quiz at jsdate.wtf

Saddest 4 word story just dropped:

“For sale: American Dream”

so far the primary complaint i have with the iOS26 betas is that everything is visually so large, scrolling through messages and it’s hard to see a thread because the ui is so dominant

corner a new way to explore the world

at the moment i’m torn on using Corner (get.corner.inc) vs doubling down on Google Maps which has a lot of historical location data, but it’d be nice to have social location sharing back again

What’s the classic foursquare for an #atproto world?

New blog post: using UnoCSS to do fun experiments with highly adaptive color utils. No more `bg-primary-hover` tokens! What if instead of flattening system rules into token lists, we encode them as live, functioning... rules?
