Yeah it's really frustrating and JS string builtins are not a good fit for me as I do not want to deal with 16-bit code units.

I am excited by the prospect of booting Wasm binaries without any JS glue, but when I've looked at the documentation for the component model and WIT it says that resources are references passed using a borrow checking model. That would

Combining OpenClaw with sensitive personal data is a recipe for disaster.

Permissions can be handled with capability systems. Keyhive [0] is the furthest along on this. I've also made my own prototype [1] showing how certificate capabilities can be composed with CRDTs. [0] https://www.inkandswitch

> I'd guess that the Racket internals are now easier to work with than Guile's Maybe, I couldn't say, but I find Chez's source code very cryptic and hard to read. More so than any other Scheme implementation.

Guile, being a bytecode VM with JIT currently, loses to Chez/Racket overall but it's honestly quite fast. I can make games that run at a smooth 60fps with infrequent GC pauses. Plenty of room to grow but Guile isn't slow by a

That's how I see it, too. I used these benchmarks early in Hoot's development as a rough measure of r7rs compliance and only occasionally as a guide for improving performance. I never published my results but I had Hoot passing mo

This is not the smallest REPL binary out there but it's far from the largest I've seen. My anecdotal evidence suggests it's somewhere in the middle or maybe smaller than average. We haven't configured our web server to

The annoying thing about that proposal is having to use 16 but code units instead of 8 bit. I hope the stringref proposal can get beyond phase 1 because that does strings right imo.

The animation on the Syndicated Actors home page [0] does a pretty good job of showing the difference, I think. Goblins is much more similar to the classic actor model shown at the beginning of the animation. The "syndicated" part

We should have a FAQ! We get the Erlang question a lot. In short, Erlang actors are not capabilities because processes can be enumerated in Erlang. Capabilities require that the actors/processes have unforgeable/unguessable priv

Yeah those interested in Wasm topics might find https://spritely.institute/hoot/ interesting. It's not only a Scheme compiler but a full Wasm toolchain available as a library.

That's right! We are developing our own stack at Spritely but OCapN is a protocol to be implemented for any and all programming languages so we can have interoperable capability security over the network. Besides our Scheme implementa

Always interesting to see an older article come back around. I could probably update this a bit for 2026 but my workflow is just about the same now as it was then. Guix is good and just released 1.5.0, check it out.

It's possible to do continuations on Wasm now and it will be made even easier by the stack switching proposal.

Came here to see if anyone mentioned propagators. That thesis is excellent. I second the recommendation.

But do you want your web browser to have the privilege to read your SSH private key? That's the risk of running programs "as you".

by davexunit 10mo ago
The whole problem is mapping privilege to users and groups, so doas doesn't solve the issues explained in the article. > The key difference here would be that www-deployment can not delegate as easily to arbitrary users, as they wou

It's nice to see other people writing about the capability transfer feature of Unix domain sockets. File paths are not object capabilities, but file descriptors are. Using a privileged daemon on top of an ambient authority system like

Despite not being an ML programmer, I found the spec pretty easy to read for the most part. One of the least intimidating specifications I have ever read, surprisingly.

I personally do not want to write HTML and I especially do not want to encode logic into it. This wave of HTMX-likes has some interesting ideas but encoding it all into HTML just feels so wrong to me. JSX is likewise awful. We need real pro
