I'm working on Lightningbeam (https://lightningbeam.org), an integrated multimedia editor. It's inspired mainly by Macromedia Flash, Apple GarageBand, and Kdenlive. It combines animation, audio and video editing into a single timeline. It's cross-platform, running natively on Linux, macOS and Windows.

I'm currently rewriting the UI in Rust - previously it had a Rust backend and a JS frontend using Tauri, but I ran into bandwidth limitations which prevented it from being really usable as a video editor. It's currently in early alpha.

This demo is really impressive: https://huggingface.co/spaces/mistralai/Voxtral-Mini-Realtim...

Don't be confused if it says "no microphone", the moment you click the record button it will request browser permission and then start working.

I spoke fast and dropped in some jargon and it got it all right - I said this and it transcribed it exactly right, WebAssembly spelling included:

> Can you tell me about RSS and Atom and the role of CSP headers in browser security, especially if you're using WebAssembly?

Doesn't seem to work for me - tried in both Firefox and Chromium and I can see the waveform when I talk but the transcription just shows "Awaiting audio input".

I feel like this creates a hash value and the real question is how unique of a value does it represent and how easy it is to narrow it down given throwing a dictionary at it. Similarly, unknown names could likely be teased out like a one-time pad. If they appear in multiple sentences then their randomness quickly repeats and becomes something that potentially could be isolated from the rest of the words around them. This would probably be a fun problem for a cryptography class to work on.

If so, then finding the redacted string would be similar to trying to brute-force a hash (though presumably slower, since text layout algorithms are probably more complex than a single hash invocation).

It would be nice if this told you upfront how many questions there were - after sixteen with nothing changing I figured it was probably endless but apparently there are twenty?

Over the many years Wayland has been promising to be a better toaster, I have tried to use it.

Every single time, I had to go back to X11 because shit simply don't work.

At this point, I am dead convinced that Wayland is simply broken by design.

As a matter of fact, they justify their existence by systematically pointing out how broken the architecture of X11 is and how a "modern" replacement is severely needed.

True, X11's architecture is indeed bad and creates lots of problems.

However, unlike Wayland, it DOES WORK.

Also, and very unfortunately for Wayland, the team working on it seem oblivious to the fact that trying to replace a badly designed system does not automatically make the replacement any better.

At this point, I would call Wayland a complete failure.

Worse, they've been at it for over 15 years and it is still fundamentally unusable.

The fact that Ubuntu is planning to deprecate X11 is, at this point in time, a catastrophe as far as I'm concerned.

The only reason I use Wayland is display scaling - with a high DPI screen, many apps are blurry or inconsistently scaled under X11. Given the parade of other issues Wayland brings, I wish the development effort were instead spent on improving highDPI support in X11.

What makes that curve exponential?

skykooler · 9 months ago

Starting at an initial density of air, suppose you descend a distance D such that the air density doubles. Now your air is twice as dense, which doubles the pressure underneath it, meaning if you descend a further D the density will double again. Continue ad infinitum (or at least until the ideal gas law stops being a good approximation).

This is because of Newtonian gravity being inversely proportional to the square of the radius, right?

skykooler · 9 months ago

Gravity changes little over that distance - it's more because of the compounding effect of atmospheric pressure (the deeper you go, the more air you have above you which raises the pressure, raising the density and meaning that pressure increases exponentially faster).

An interesting corollary of this is that if you only have a single sample, it reduces to indicating that your sample is the median value - i.e. if you see one item with serial number N, you can guess that there were roughly 2N produced.
