briarpress.org is an amazing community and practicing a craft is fulfilling. And: watching the last generation of professional printers age, keep up the hobby in their garages, enthusiastically answer a dwindling number of questions on internet forums, and pass away, has been: sad. We lost so much.

So we're all made of stardust AND we only exist because several of our ancestors caught the worst colds of their lives and ended up with superpowers. Cool.

Hell yeah

RIP little buddy. I replaced your battery and lightning port last year, but yesterday, I set you on a Qi charger and you got *very* hot and now the 1x camera won't focus. It was a good run. It was a _great_ run.

One of life's great joys is to witness someone–anyone–doing something–anything!–with skill and (I'll say it) love. Basically, this is gonna be like Jiro Dreams of Sushi, if Jiro was funny, had a Boston accent, played Megaman, and every time he miffed it money went to a great cause.

So here's an interesting little thing or 2 @nomster.bsky.social , @foolip.org , and myself have been cooking up—along with lots of help from others!: developer.chrome.com/blog/declara... This could lead to some VERY interesting changes in how we write web pages. Would love to hear your thoughts!

📣 🚨 🪩 I'm delighted to announce "Funding The Web: a covenant for browsers, search, and people", new work from yours truly generously supported by D//F: ftw.fund. It's a complicated topic but it only impacts the whole web, so please bear with me a little! 🧵

✨ I just released a new (free!) tool for creating custom Bézier curves! courses.joshwcomeau.com/tools/bezier It has one special feature that I haven’t seen anywhere else, and it allows us to do something pretty cool. 🧵

When I was working on the responsive image client hints, we talked about fingerprinting as an abstract threat.. it’s really something to read through a thorough breakdown of a big, real example: browsergate.eu/how-it-works/
