It depends on the process. Argon/CO2 is used for MIG welding, while TIG generally uses pure argon. In some situations that justify the expense, helium is used instead as it allows deeper weld penetration.


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.


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".


For me it shows the waveform and then "error"


Try disabling CSP for the page


Same here. In Chromium I don't even see the waveform.


I had to turn off ad-block to get it to work.


I can see the waveform but it still doesn't work for me. Switched to Edge, disabled all adblocking and privacy extensions, built-in tracking prevention, and "enhanced site security" (whatever that is), and still no dice. I'd love to try it and be impressed, but it seems impossible. :(


Did you check if your mic even works in principle? E.g. using https://www.onlinemictest.com/

If you don't get sound there it won't work anywhere. A surprising number of problems like these can be solved by selecting the correct audio input source (provided your computer shows more than one).


Yep. Mic works fine. My mic even works on the test page! What doesn't work is any of the transcription functionality. :(


I just bit the bullet and did it via python and the api.


Same here on iPhone with Arc Search.

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?


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.


O man I recently tried to use fractional scaling on Wayland, and it went very poorly. Electron apps like slack or signal do not support it, and flameshot also works very poorly. But I guess at least fractional scaling is to an option... (Which I had to enable in some secret setting somewhere)


In xfce, setting DPI in Appearance works perfectly (in my experience). Just don't try to scale with display settings...


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).


What makes that curve exponential?


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).


Newtonian gravity (classical mechanics).

Two-body gravitational attraction is observed to be an inverse square power law; gravitational attraction decreases with the square of the distance.

g, the gravitational constant of Earth, is observed to be exponential; 9.8 m/s^2.

Atmospheric pressure: https://en.wikipedia.org/wiki/Atmospheric_pressure#:~:text=P... :

> Pressure (P), mass (m), and acceleration due to gravity (g) are related by P = F/A = (m*g)/A, where A is the surface area. Atmospheric pressure is thus proportional to the weight per unit area of the atmospheric mass above that location.


Was there an issue with this answer about why water pressure is?

Are you donvoting according to preference or to Terms of Service?

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.


You do have outliers though. Seal Team 6 is actually Seal Team 1 but they wanted people to think they were outnumbered.
