It's been a long road, but TCP ingress for Workers is finally here.
gRPC support is now available in Cloudflare Workers. You can now route, transform, and serve gRPC services natively at the edge without maintaining dedicated proxy infrastructure or translation layers. Read the launch post: https://cfl.re/4fMsitT
I really tried to like Shroud. It's well written but the pacing is way too slow, and the characters are entirely forgettable and uninteresting. The concepts are there but it just felt like a journey going nowhere.
🪐📚💙 I’m reading the 2026 Hugo Nominees! Shroud by Adrian Tchaikovsky, 436 pages. I’ve some mixed feelings. The story is well-written and I love the concepts in this one, especially the sense of alienness. The tech felt well-grounded without taking over the story. #booksky #adriantchaikovsky
So.. on a day next where the temperature is expected to reach 104 degrees F ... the power company has decided to schedule a multi-hour maintenance outage during the time of day that is expected to be the hottest time of the day.

Very happy to say that @cloudflare.social is a Diamond level sponsor for this year's @nodeconf.eu ... also thankful for all our sponsors!
I just saw a meme that said “get in losers, we’re reclaiming the emdash”. People. PEOPLE. Where are your STANDARDS? It CLEARLY should be “get in, losers — we’re reclaiming the em dash.”
The Error code property proposal has advanced to Stage 2 ... github.com/tc39/proposa... WHATWG folks have raised an objection based on a potential conflict with DOMException's legacy code property. We'll need to figure that out in order to push further. github.com/tc39/proposa...

Some notes on www.jasnell.me/posts/http-s... to address some of the feedback I've received so far ... 1. It's not compatible with any existing server! That's intentional. While many runtimes current implement some variation of using Request/Response or Node.js-compat there is no common API surface

I've also been one to try out new kinds of input devices. I recently came across the mudra link (mudra-band.com) and was fascinated by it. I picked one up last week and, for the most part, it's actually quite a neat little device. There's one challenge with it for me tho...

I'd say that ICE agents are likely the only population whose cumulative and average IQ's are the same single digit integer... but it can't be given that there people who support and enable them.
Fuck ICE. Fuck literally every single individual who works for and willingly supports them.
WHOA DHS does not say that the agent feared for his life… just the vague concern for “public safety.” So he killed him just because he did not want him in America, not because of any specific threat to agents?
atproto has one big idea: apps should be lenses rather than boxes this idea is still unknown to majority of internet users. even to the majority of web developers we’re still at a phase where, if you explain it to someone, you can literally see it clicking for them in real time
