Note that there has been controversy for the last few years around Culture Hustle not fulfilling orders and doing other sketchy things. Just a heads up.

Agreed. Virtualized 3d acceleration in particular still has quite a bit of "secret sauce" left in it.

If this is truly meant as a PoC to raise awareness, shouldn't there be a writeup of how it works and/or source code? I'm not interested in running some random binary that claims to hack a game, but a technical description of the vuln would be interesting.

It's the Erlang runtime/virtual machine, like the JVM is for Java, Scala, etc.

Current US mail trucks are right hand drive so the driver can deliver to curbside mailboxes without getting out.

Probably an isolation transformer. A search for “cable tv isolation transformer” gives lots of results.

I bet you could get a lot better color if you used the screen itself to generate the bayer pattern on film rather than printing it with a printer.

Get some large format color negative film and thin cyan, magenta, and yellow filters. Put a cyan filter on the LCD, followed by the film on top. In a darkroom, light up the "red" pixels and to expose that part of the film. Repeat with the magenta filter and "green" pixels, and finally the yellow filter and "blue" pixels. Develop the film and reattach to the LCD.

This is kind of how the shadow mask was made in color CRT monitors. A photographic process was used to put the red, green, and blue phosphor dots on the screen by shining light through the shadow mask from the same angles the electron guns would later illuminate the phosphors. This ensures that the red, green, and blue phosphor dot pattern lines up (fairly) accurately with the shadow mask.

Yes this issue is still there unfortunately.

Free electron lasers generate X-rays using a single pass through the lasing medium, which is essential because you can't make good mirrors at those wavelengths either.

As a fuel. And yes, it's the same principle.

I would guess it comes from calling the universal quantifier ”for all” in logic
