New preprint: we used k-mer matching with suffix match length information to create an assembly-to-assembly alignment algorithm + software for bacterial genomes, kbo.

kbo uses the SBWT data structure which lets us run a query in 1-10s and 500-1000MB RAM, depending on the task and parameters.

All our algorithms run in the browser, try the tool at maklin.fi/kbo/ There is no server-side processing, so the data never leaves your computer.

k23 (the Wasm OS) just got a shiny new async executor! But we need your help:
The executor is likely full of concurrency bugs, deadlocks and worse.

So if you want to help out the project an absolute ton head over here and help get kasync tested:

New #Topiary release. This is an incremental release. The headline changes are bumping Tree-sitter to v0.25, as it was blocking some users, and better support for Nix sandboxes after 0.6 introduced dynamic fetching. You'll also fine support for formatting #Wasm Interface Type thanks to returning contributor Mikhail Katychev. Thanks a lot!

@gabe_sky That's a great page - it's always the first 10 links on Google you need to skip usually :)

I took the time to work on my DHT-based storage system running in the browser, and now it works nicely with simple javascript:

If you connect through the above link, your browser becomes a node in a decentralized network, and fetches this page from one of the other nodes! For more information, visit

@mcc i would like to know the answers to your questions, too. i've been investigating Rust/WASM + some libs? tauri maybe? as 100% Rust alternative to, i dunno, Typescript. like, scroo JS period except as needed/used by Rust libs I'm depending on.

is this possible? desireable? seems like what you're trying to do is the first step

🌀 Introducing **Chakra** - a blazing fast in-browser WebAssembly runtime for builders.

```sh
chakra myfile.wasm
```

– Runs WASM in-browser with logs
– Supports Rust, TinyGo, C, Asc and Python
– One-line introspection & verify commands

Chakra is an open source project and we're building it *with the community*.

Ruffle remains the most compelling argument for Rust and WASM as technologies. Anything that allows one to once again experience sbemails in their original vector-art glory is clearly a net positive for society.

PPCI support assembly generation from #wasm code!

⚡ Why I use WebAssembly | nasso.dev

｢ My favorite way to use WebAssembly is as a way to share code between platforms. Write the core logic of your application in Ru… a language that can easily compile to native code and WebAssembly 😊. In this architecture, most of your code is shared between the “native” and the “web” variants of your app ｣
