Hope my post didn't come across as complaining because I agree! Wasm is great right now for lots of things, just wanted to highlight a use case that isn't great yet.

In Scheme what you want to do is allocate a big bytevector and use it over and over. This is what I already do outside of Wasm. I don't want or need linear memory involved, I just want access to my (array i8) from JS.

Thanks for bringing a reasonable perspective to this discussion.

Yes, I know there's more overhead on the web than native, but that is missing the point of my post. I'm talking about issues with Wasm GC relative to other ways of rendering with Wasm. I've played many browser games with go

Perhaps I should've said this in the post to ward off comments from the anti-GC crowd but I do realtime graphics in managed memory languages just fine outside of the Wasm context. This is a Wasm problem.

This was a quickie post for me. Just a tale of what my experience has been. No in-depth, apples to apples comparison so I don't know the magnitude of the performance differential.

by davexunit 2y ago
Yes, that's right. I'm hoping there will be a way to do this in a future revision of Wasm GC.

by davexunit 2y ago
Sorry but it's just a different choice not a mistake. I do realtime graphics just fine in non-web managed memory languages.

by davexunit 2y ago
Slower, single threaded, greatly increases binary size, separate heap from JS so bad interop with extern refs. Wasm GC is a great thing.

As mentioned, that works quite well already but it's not the topic of this post.

Stack switching in wasm would be great (as long as they aren't nerfed which they might be!) but note that Hoot has fibers right now : https://gitlab.com/spritely/guile-hoot/-/tree/main/lib&#x

Since everything would be speaking OCapN you could use the browser interface as a convenient command center. This idea is becoming quite appealing to me actually... would be cool to have a little dashboard showing the health of my servers a

> I wonder how hard this would be to port to Hoot It would be interesting, though I don't know if it would make sense. In any case, the way to do it would be to extract all the code that does POSIX things into an abstraction layer.

Actor systems can handle unpredictable errors and if you watch a recent talk by Douglas Crockford about actors/Misty there are Erlang-like "let it crash" examples.

There are many layers of capabilities. Unguessable process IDs would be necessary for network capabilities. A sandboxing environment would be necessary for system or process level capabilities. It's still worth having the network se

by davexunit 2y ago
Right, they would need to be unguessable to be used as capabilities.

Shepherd is a wonderful little service manager. The project has been integrating the good features of systemd (socket activation, timers, etc.) while retaining the hackability of using a fully featured programming language for configuration

I should clarify that when he calls it vaporware he means that he is interested in propagating the actor model concept rather than any specific language or implementation.

by davexunit 2y ago
Douglas Crockford has described Misty as vaporware (hence the name), whereas at Spritely we are building and shipping things that can be used. Rather than build an entirely standalone domain specific language, our research and development b

Erlang actors are not privately addressable, so they cannot be used for capability security. The actors described here are.

Wrapping file i/o in actors is exactly what we do in the Goblins distributed programming system. It ensures that only one operation is happening against the file descriptor at any given time while allowing other actors to use it asynch

What line of cymbals? A? K? Something else? Zildjian make quality stuff but maybe you'd prefer either a different line of theirs or another brand entirely like Meinl or Sabian. You never break as many sticks and cymbals than when you&#

Yeah, electronic cymbals just don't feel right at all. The price to pay for being able to practice somewhat quietly, I suppose.

by davexunit 2y ago
I'm a long time fan of Sabian cymbals but good lord their new logo is so awful. The old one was way better and it's especially bad when compared to Zildjian's iconic logo.

Maybe, but I haven't pushed very hard for it as I don't use OOP very often. I did buy Art of the Metaobject Protocol in case I wanted to try to make some of the improvements myself, but haven't gotten around to it.

Strange to see this show up on the front page now when I wrote this back in 2022. For context, this is a light critique of Guile's CLOS-like OOP system which overall I think is a pretty great approximation of CLOS. I just wanted to wri
