I ported Zelda Classic, a 20+ year old C++ Allegro program, to the web:

xfinity.com wins the shitty website of the month award. every other interaction takes 5s to do anything, support pages 400 (unless you are logged out or in incognito), and live chat is broken

was being generous. some stuff takes minutes to finish. glanced at a trace and yup, some custom made shit analytics framework. they'd see people dropping out of their flows in their dashboards, if it weren't for the fact that no one has a choice in internet service.

so, how normal is it to come across an error in MSVC codegen?
Straight up bug in the compiler. 100% not undefined behavior. The assembly is obviously doing the wrong thing.

imagine having all this tech, and using it to do the most boringly unimaginative thing ever. a cumbersome virtual tablet with resolultion worse than a TV from 2007

Dogfooding is a super power. @vercel's website is constantly automatically updated (with PR review) to run the latest canary of @nextjs.
Not gonna lie, sometimes it hurts to run the cutting edge, but the payback is huge. E.g. yesterday I was like "Why is vercel.com/ai-accelerator so slow?"
Turns out there was a bug in the Next.js canary that was loading more CSS than necessary for a given route. We fixed it upstream, repushed, and prevented this bug going out to all users of the framework before the next release.
We'll add automated tests to catch similar issues going forward.

TIL that a $ (A$3 instead of A3) denotes an _absolute_ position in a spreadsheet. So when you copy/paste, those references don't get modified relatively! mind blown

eli5: depending on the app my tv is playing (netflix, youtube, even different videos across YT; whatever) I have to vary my volume by up to 15 notches to maintain a reasonable level. i have an AVR and a 3.0 sound system. what am i doing wrong or is this just unavoidable

i just successfully consulted the x64 developer's manual and solved a bug. i can feel my beard turning grey

probably the simplest proof that journalism does not really take advantage of the web as a medium is when an article references a time with a fixed timezone, no matter what timezone the reader is in.
just... convert it to my timezone 😭
