I find it telling that the highest praise for LLMs comes from people using it for something where they admittedly have very little domain knowledge. Domain experts usually mention major caveats. I've been testing them on subjects where I already understand the problem well, and I've yet to see any outputs that would make me trust them on things I don't already know.

I suppose everything is okay as long as it's done inside of a building.

We don't know where exactly viruses came from, but one of the leading theories is actually that they are the descendants of bacteria which outcompeted other bacteria. When a parasitic bacterium sheds more and more of its own metabolic capabilities, because it's more efficient to steal those abilities from its host cell, it evolves in a way that looks more and more like a virus.

"More evolved" or "more advanced" in this case doesn't mean "bigger" or "more complex". You can say viruses are equally evolved as bacteria, meaning they've spent equally long being optimized for their ecological niche.

I just checked my `~/.local/share/libvirt/`. It doesn't do this for me, and I don't think it ever has.

I do remember having to set this up at some point. Looks like this is it:

There are some limits around network ports in User Sessions, but it should suffice for anything you'd use Vagrant for.

> Creating a new VM? You're forced to pick an OS by typing the name of your OS into a search box which is tedious and doesnt give you an option for generic x86 machine.

...There is though? It's in the dropdown under "Generic or unknown OS. Usage is not recommended (generic)". Here it is in the code if you don't believe me:

And a random tutorial which makes use of it:

No. The antenna elements are always plugged in the same way. By sampling/introducing the signal at a different physical position on the lens (or multiple positions simultaneously), you create different physical distances and phase shifts for each element, and therefore a different beam direction.

...Apropos of nothing, this reminds me that a long ago, I played on a Minecraft server where one of the boys made a piston display with controlled by a pressure plate array. I was shocked by how he managed to transmit the signal with a simple wire. Maybe it was a similar idea, using the propagation distance...

> If the output ports are connected to individual antennas in an antenna array, this allows shaping the beam in different directions by switching which input port the signal is sent to.

From TFA.

Presumably the geometrical shape of the lens is dictated by solving for useful phase shifts for different input points. Otherwise you could just use a bunch of delay lines.

I wonder if anybody's ever designed a 3D version of this. You might get a wider range of inputs, or more precise steering, by shaping the delays on a non-Euclidean (curved) surface (like a sphere or a saddle).

Literally all of them are using it as part of non-user-facing debug tools for 3D graphics:

Meta as part of their VR/gaming division, Google in their VR division and 3D rendering engine, Ikea in a 3D material editor, and Intel in a 3D SDK.

And again, the intended use is immediately explained on the project repo no matter what the comment you were replying to said.
