The thing I want to achieve with WebAssembly is still proving a lot harder than I had anticipated. I want to be able to take strings of untrusted code provided by users and execute them in a safe sandbox. I have all sorts of things I want this for - think custom templates for a web application, custom workflow automation scripts (Zapier-style), running transformations against JSON data. When you're dealing with untru…

Hey Simon, I've done some similar experimentation using Extism to sandbox LLM generated code. This uses our JavaScript PDK (which uses quickjs) and can be embedded in any host language we support https://extism.org/blog/sandboxing-llm-generated-code

I'm also working on a Python-PDK right now and hope to have a beta ready in the next month. That would allow us to do something similar with python.

Another open Source project locking their community discussions away on Discord where it can't be easily discovered or searched. At least consider mirroring to the web - or at this stage inform people you will one day make posts available on the open web. Acquiring that consent afterwards is painful.

hear ya loud and clear -- and we use multiple forms of communication.. GitHub issues and discussions are actively suggested when we find that a conversation is turning into something that would benefit others and move from Discord.

Discord is really advantageous for us to have real-time conversations with people though.

Is there some service available for mirroring discord chats the web?

This blog article is great, I had a hell of a time integrating Wasm into Ruby, so much so to the point that I gave up. I was absolutely going to call a function, pass it some HTML to parse (as a string), and return a number, but what I wound up doing is pass a directory with some HTML file in it, return a number as a string, and parse it. Because after struggling with wasmtime and wasmer until I could see it was not…

This is great so far btw! Going to watch this whole talk today.

There's a lightning talk version from GitOpsCon (at GitOpsCon/CDCon Vancouver - co hosted with OSS Summit later in the week)

But they are pretty much the same talk, except at CDCon, I hadn't written the Kubernetes operator so that it actually ran the Wasm module yet. At the end of the talk at OSS Summit, I show it running and I'm so glad you enjoy it! I will definitely check out your new ruby SDK :tada:

The idea of Wasm as a universal plugin system is very promising. But string passing is maybe not the best example to highlight, considering that Wasm is introducing stringref to enable zero-copy string sharing between the Wasm runtime and host language. https://github.com/WebAssembly/stringref/blob/main/proposals...

A quite old idea,

Earlier quoted context omitted.

While it'd be a nice addition, I wouldn't expect it any time soon. It's currently still a stage 1 proposal, while we've been waiting for years for other proposals to be merged. The last time a proposal was actually finished was over 2 years ago. https://github.com/WebAssembly/proposals https://github.com/WebAssembly/proposals/blob/main/finished-...

Indeed, webassembly is moving extremely slowly. I started a project years ago expecting https://github.com/WebAssembly/memory-control/blob/main/prop... and https://github.com/WebAssembly/memory64 to be fixed at some point. Neither are yet, and the project still suffers from it to this day. I think wasm is still great without these fixes, but I have lost confidence in the idea that wasm will reach its full potential a…

Eventually people will realise its potential is being yet another bytecode format, with VC trying to capitalise products on top of it.

I really miss forums tbh, what happened to them?

It feels like Discord has replaced the good old forum but it's worse in so many ways.
