JS has proper async stacktraces as well, or do you mean something else?

Great work! Strangely, I thought I remember being able to use breakpoints on https://cloudflareworkers.com/ - I thought it handled inspector messages in a nested loop until receiving debugger resume command - since the begi

> What prevents developing a wrapper or shim that runs any wasm as if it were any other native executable? That definitely exists and is used on server-side - Wasmtime, Wasmer and others.

Thanks, be sure to check out the part 2 as well :)

Don't know about webcams - usually (unlike in OP's case) those already have good OS-level support, but I did port gphoto2 to Wasm+WebUSB for access to DSLRs & mirrorless cameras: https://github.com/GoogleChro

Browser ports can't integrate at OS level, they're intentionally separated today, but given that e.g. Node.js has WebUSB support ( https://github.com/node-usb/node-usb ), I guess you could make a layer that exp

Chromebook is probably the perfect target for those kinds of ports. Definitely worth giving a try, hopefully SANE supports it.

That's been already blocked by Google, with reviews deleted, so not much I guess.

Or it could apply gzip/brotli + optionally wasm-opt and cut the size ~5-6x: https://twitter.com/RReverser/status/1494435774003093515

The sad part is, it could be cut very easily cut down to ~60MB with basic optimization & compression (heck, even gzip/brotli compression alone would go a long way): https://twitter.com/RReverser/status/149

Ah, I see. That would be interesting, but removes the cross-platform compatibility from the equation, which, for me, is the most valuable piece of WebUSB and other similar APIs.

Glad to hear! If you want to give it another try, you should be able to use my linked libusb fork in any app that depends on libusb, and compile that with Emscripten.

I didn't see it but did think about it. I think it should be possible by wrapping WebUSB into something like Comlink, e.g. I know Surma experimented with allowing Comlink to be used with WebSockets: https://twitter.com/

With guiding you're usually aiming for 5-10 minute exposures per frame. That usually results in each frame having at least several streaks. Sure, those are technically still short and can be cancelled out, but astrophotography is alrea

One is looking at it, another is polluting it and precluding others from looking at it. Surely you see the difference?
27.
by RReverser 5y ago
For pure visual observation you might be right, but any sort of amateur astrophotography is already significantly affected and is only going to get worse because 1) it's usually more wide-field than in professional observatories, which

> Limiting it to installed apps still has the problem of users blindly agreeing to something that is fundamentally super dangerous. Same can be said about native apps. Like with other hazards, in the end it's all about balance - you
