Those benchmarks from @t3.gg revealed some interesting issues in Workers. Happy to say it's all fixed now, save for some lingering next.js-specific stuff we're continuing to work on. Thanks for the reproducible test cases, @t3.gg. Excessive details in blog post: blog.cloudflare.com/unpacking-cl...

Hey Bluesky, I know how people here just LOVE everything AI, so I wanted to show you what @threepointone.bsky.social and I have been up to. We made an agent that calls MCP not as "tools", but by converting the tools into a TypeScript API, and writing code against that. blog.cloudflare.com/code-mode/

Did search. Would eat.

I think adding the .map() thing was worth it just for the engagement on these threads lol.

I don't have a problem with making new RPC systems! I can stop any time I want! But I don't want to. So I made a new one for you. It's called Cap'n Web. It's like Cap'n Proto RPC, except focused on working great in browsers and JavaScript/TypeScript servers. blog.cloudflare.com/capnweb-java...

My smoke detector. In case you can't hear it over the alarm, it's saying: "Too much smoke, alarm cannot be hushed." Four different detectors in my house have had false alarms now. All Kidde-brand. Apparently this is common with Kidde. @bradfitz.com I am feeling your pain (a decade later).

Holy shit. This guy saved a PNG to a bird. (he drew a bird into a spectrogram, played that sound to a starling, and the starling reproduced it back to him with enough accuracy he got his bird drawing back in their call's spectrogram) www.youtube.com/watch?v=hCQC...

Ridiculous. The time Google is spending just on comms to deprecate this is likely an order of magnitude more than it would have cost to just keep these links working forever. One could implement this on Workers in 5 lines of code and never touch it again...

Midnight power outages in 2025 are like being haunted: - HVAC fans suddenly go silent - Weird beeps and boops from around the house as charging devices complain they stopped charging - Phone notifications blowing up - Powered shades occasionally go up and down randomly (wtf??) - Distant car alarm

I find that the most effective way to get rid of a headache is to exercise. I also find that people with headaches are not receptive to this advice.

Came here to make a "'JD Vance kills the Pope' was not on my bingo card" joke but it turns out literally everyone already made that joke it so I'll see myself out.

We had @linusmediagroup.com over for a LAN party! www.youtube.com/watch?v=97Y0...

I posted a new video, in which I demonstrate the "Rupert Property" for a bunch of polyhedra: youtu.be/evKFok65t_E

Hate to say but... I did not like Severance. Great premise! Too much weird shit, nonsense, and inconsistency. I couldn't suspend disbelief. Amused this came from Apple as it seems like it's actually their fantasy office? Annoyed I paid Apple money for the first time in a decade to watch this.

I saw the Goodyear blimp outside the window and I took a picture and sent it to @jadewang.me and typed "blomp", which was a typo, except now I've decided that's really a much better word anyway. It's a blomp now. Goodyear blomp in Austin, presumably for SXSW.

I've been trying a lot of AI code assistants lately... Claude Code: Holy fucking shit 🤯😱 Cursor, GPT 4.5: I would have found this impressive if I had not tried Claude Code first. Gemini code assist: This... is what I expected an LLM to be, before I tried the others.

whoa

Today we’re excited to share a few announcements on how we’re making it even easier to build AI agents on Cloudflare, including a new agents-sdk (a new JavaScript agents framework) and updates to Workers AI. blog.cloudflare.com/build-ai-age...

Hey! 👋 In ~2 months, I'm presenting a research project at Node Congress that compiles JVM bytecode to WebAssembly, letting you import Java functions in JavaScript. 😈 This'll allow existing Java code to run in the browser and new JS runtimes like Cloudflare Workers... 🙈 gitnation.com/badges/node-...

My startup shut down over 8 years ago and I still get contacted EVERY DAY by phone, text, and/or email by people offering various forms of (presumably predatory) business financing.

I figured it out, and it's so dumb: The motherboard was just confused about which GPU to use to display the BIOS UI. I configured the BIOS to use the motherboard's integrated VGA and ignore the GPUs. Now it boots fine and both GPUs work great for ollama. 🤦 bsky.app/profile/kent...

Surprisingly, I got all my my parts for the AI server and they all work. Except when I put them all together. With both GPUs in, the Asrock ROMED8-2T motherboard hangs with code b2. With either one GPU on its own, it boots fine. BIOS is updated, not sure what else to do. :(

Well well well. A Secure [AI] App Store, you say. Users control their data all in one place, you say. Users control what each app can see, you say. Make app development easy, you say. Where have I heard this before. www.ycombinator.com/rfs

This one?

I have ordered a second RTX 3090, reburbished, from some no-name Amazon Marketplace seller. It cost as much as the one I bought brand-new four years ago. Apparently linking two of these is by far the cheapest way to self-host AI models requiring 48GB VRAM? (diclaimer: I'm an AI noob)

FF16 be like... "Wolves are attacking our village, can you help?" "In my most recent battle I fought a dragon god. We launched ourselves into orbit. He fired gigawatt lasers at me and I responded with nuclear fireballs. I won. These wolves might be tough though, I'll see what I can do."

Hey, there is a new blog post for people who are interested in pointer compression, isolate groups, and sandbox in V8. dbezhetskov.dev/multi-sandbo...

The staircase to my second floor has 17 steps and I find this infuriating.

Hate to say it but since implementing auto-formatting in our C++ codebase I think we've spent 1000x more time fighting the auto-formatter than we ever spent arguing about formatting.

this reminded me of a dub I made about Cloudflare a couple months ago. just regenerated it with durable objects context

There should be a way to short-sell overhyped technologies in general. I could have made so much money short-selling VR/AR a few years back, and then lost it all short-selling blockchain.

December power usage. Can you spot the 48-hour LAN party?

DRAM failure light on your motherboard? It might mean: - You need to update your bios. - Your CPU is fried. It does NOT mean: - Anything is wrong with your DRAM. True across all chipsets, Intel and AMD, AFAICT (4 data points so far).

doing my best impression of a devrel

Friends are arriving tomorrow for multi-day New Year's LAN party, so today I went on a 45-mile bike ride to charge up my "right to drink beer" meter. That's how it works, right?

Startup idea: Sell the dumbest possible TV that acts as a chromecast/airplay target. No other UI, no apps, it just plays the casted video and turns off. Sell as a luxury product, high margin. I will buy it.

Can someone please add bindat() and connectat() to Linux? With same semantics as FreeBSD. Motivation: - All the usual reasons why -at variants exist for syscalls that take paths. - Easier to work around sockaddr_un.sun_path length limit of 108.

"Hah! If I use a fake ID and a 3D-printed gun they'll never be able to find me!" *continues to carry said fake ID and 3D-printed gun days after the crime* ... really?

how do you all remember every UUID? I find it really hard. so I wrote them all down on every uuid dot com the list has fast search across all 2^122 values (so you can find your favorites) - hoping to add some social features like "trending UUIDs" soon!

Been working on making it possible to connect Claude Desktop to a Cloudflare Worker using the new MCP spec, and it works! You write some functions in a Worker, document them with JSDoc, and then they show up in Claude for you to use. It's kinda magical. github.com/geelen/worke...

Linux: Oops, we're out of memory. Guess I'd better kill something. How about gnome-shell? That's not important, right? Meanwhile...

Well this is fun. www.youtube.com/watch?v=nzI_... (Note: House in thumbnail is some other house.)

Just implemented and deployed a complete GitHub oauth login flow /entirely on my phone/ using Claude and Cloudflare Workers

My mom dug some stuff out of storage.

I figured out why my HVAC energy usage was so high. This is embarassing. The fans were on high rather than auto. I didn't think it would make a difference because it was the heat pumps, not fans, using the energy, but somehow fans on high makes the heat pumps run more.

Everyone is making fun of my $20 keyboards but they are all wrong. The keyboards are not $20. They are $13.

It's amazing how many news sites will just straight up steal my photos, slap some ads around it and repost it without even asking. Props to @pcgamer.com for being the only ones who actually asked permission! Boo to the ones that didn't even link back to lanparty.house.

Durable Objects are THE great enabler. #BuildingCloudflareOnCloudflare
