The situation where a certificate's private key only has 8 bits of randomness instead of 384 is unacceptable.
We should urge all certificate authorities to immediately publish their private keys so that the community can make sure they are random enough.
we are joining Cloudflare - so excited
We are excited to announce that Deno is joining Cloudflare!

this is cool n all but can we get this in the real world pls so it to fold my laundry man
We’re sharing a solution to the Navier-Stokes Millennium Prize Problem, one of the deepest problems at the frontier of mathematics.
The proof was produced by a group of agents, using an OpenAI next-generation model significantly more capable than GPT-6 Astra.
The problem concerns whether the description of smooth three-dimensional fluid motion modeled by the Navier-Stokes equations can break down. It has remained unresolved for roughly 90 years.

celld 0.4.1 released!
- active cell rebalancing when scaling number of celld instances
- paged reads to handle large cell databases better (no longer downloads whole database before queries can be answered)
- 10x better Queue throughput
- Support for Durable Object Facets
release notes github.com/denoland/celld/re…
R2 support!
celld 0.4.0 is released! In this release we fill out a lot more functionality beyond Durable Objects and Workers. celld now supports:
- KV
- Queues
- Workflows (durable execution!)
- R2 (using the bucket that celld is connected to)
There has been a ton of work done on reliability, correctness, and performance. We're still considering this an Alpha preview, but aiming to update that status to Beta soon.

A lot of people have been asking for an explanation about how dactyl.dev works
It's actually quite a bit of magic emulating iOS in the browser. I wrote up an explanation here:
dactyl.dev/blog/how-dactyl-w…
IOS SIMULATOR IN THE BROWSER
Introducing Dactyl
Dactyl is a vibe coding platform for native iOS and native Android apps. What's interesting about it is the device simulator: we've built a SwiftUI renderer in WASM.
This means as you're developing, you get low latency in browser canvas simulation of the app to play with. Also things like oauth flows happen in the browser.
If the app uses the camera - the browser camera API allows us to display it in the simulator.
We also let you connect your ChatGPT subscription so you don't have to buy tokens through us (+ markup)
Through [magic] - we can run the same SwiftUI code the agent writes for iOS in android, with native components.
This is the work of @undefined_void (primarily), @piscisaureus, myself, and others at Deno.
It's built on Durable Objects perhaps unsurprisingly
dactyl.dev/
very similar to dgit which is on top of Durable Objects and R2 whereas walgit is on top of S3 WAL and CAS
one of my main goals with dgit was to make deploying your own git server without a VPS to cloudflare with just npx wrangler deploy
for much more customizability and control "dgit on celld" and walgit makes more sense
Git at Scale (by cursor) has been one of the most interesting blog posts i've read in a while. It came right when I was frustrated with Shopify's internal git system.
As an exercise, I've implemented it over the weekend as open source. It's a single rust binary that you can point at any S3 type object store. It uses WAL and CAS primitives and requires no other data store.
It also implements bundle-uri so large git repos (like our mono) are very fast to download as a chain of static bundles. Also comes with basic familiar UX.
