Just built a feature into relisten and if there was to be a future jamband named "track" it would have completely broken it
so I had to rename the route pathway "$track" which feels equally plausible for a jam band name

My high powered anker usb-c cables died in just two years. It can’t handle the flex.
Does anyone have good cables (160+W) that can last?

Went down a rabbit hole of discovering that there is no real recovery method for errors in RSC/SSR, except for Suspense - which has orthogonal uses.
Would love to see a new primitive in React for catching errors on the server. Here's my writeup:

This PR ducked under the radar, but was just officially released in React 19.3
Being able to render from a server component (to serialize rsc data to the client) is a no brainer sugar that makes crossing the boundary in nested situations much cleaner

has anyone's company been wrestling with their web framework or architecture lately?
i'd love to chat and find out what problems you've been running into.
this isn't a pitch meeting and I won't be selling you anything – but it will help me craft my framework's feature-set and narrative.

The stones of the react team to ship the return contract for useState hooks as an array (const [state, setState])
other teams would have shipped an object with fixed keys, not a de-structurable array

had a phenomenal weekend at dicks sporting goods park. first time there since 2014. really had a blast with the crowd and shenanigans. jams out the ears.
fave of the weekend was life saving gun, but the light, WGTYM, and wave of hope (mini kit jam) also crushed.
well done Phish, see you in a month
