I ran out of crtcs, but I wanted another monitor. I widened a virtual display, and drew the left portion of it on one monitor, like regular. Then I had a crown job that would copy chunks of it into the frame buffer of a USB to DVI-d adapter. It could do 5 fps redrawing the whole screen, but I chose things to put there where it wouldn't matter too much. The only painful thing was arranging the windows on that monitor, with the mouse updating very infrequently, and routinely being drawn 2 or more places in the frame buffer.

Have you tried turning them off, then turning them on again?

I think we're still headed up the peak of inflated expectations. Quantum computing may be better at a category of problems that do a significant amount of math on a small amount of data. Traditional computing is likely to stay better at anything that requires a large amount of input data, or a large amount of output data, or only uses a small amount of math to transform the inputs to the outputs.

Anything you do with SQL, spreadsheets, images, music and video, and basically anything involved in rendering is pretty much untouchable. On the other hand, a limited number of use cases (cryptography, cryptocurrencies, maybe even AI/ML) might be much cheaper and fasrer with a quantum computer. There are possible military applications, so countries with big militaries are spending until they know whether that's a weakness or not. If it turns out they can't do any of the things that looked possible from the expectation peak, the whole industry will fizzle.

As for my opinion, comparing QC to early silicon computers is very misleading, because early computers improved by becoming way smaller. QC is far closer to the minimum possible size already, so there won't be a comparable, "then grow the circuit size by a factor of ten million" step. I think they probably can't do anything world shaking.

You can buy high (97-99) CRI LEDs for things like the film industry, where it really does matter. They are very expensive, but can pay for themselves with longer service life, and lower power draw for long term installations.

The CRI on regular LED bulbs was climbing for a long time, but it seems as though 90ish is "good enough" most of the time.

You can just issue new certificates one per year, and otherwise keep your personal root CA encrypted. If someone is into your system to the point they can get the key as you use it, there are bigger things to worry about than them impersonating your own services to you.

A lot of businesses use the last 4 digits separately for some purposes, which means that even if it's salted, you are only getting 110,000 total options, which is trivial to run through.

Modern operating systems have made it take very little knowledge to connect to WiFi and browse the internet. If you want to use your computer for more than that, it can still take a longer learning process. I download 3D models for printing, and wanted an image for each model so I could find things more easily. In Linux, I can make such images with only about a hundred characters in the terminal. In Windows, I would either need to learn powershell, or make an image from each file by hand.

The way I understand "learning Linux" these days is reimagining what a computer can do for you to include the rich powers of open source software, so that when you have a problem that computers are very good at, you recognize that there's an obvious solution on Linux that Windows doesn't have.

Don't joke about this, the college professors will hear you.

He only believes in the first 22 words of the first amendment. If you want to speak about what he has done, or (far worse) gather with others that share your beliefs to speak extra loud... straight to jail.

This sounds like what reverseimagesearch dot org does, but that only has 4 engines linked.

Real everyone-eats-ice-cream-and-dances-all-day hasn't been tried either. Just because you describe a set of circumstances doesn't mean those circumstances can exist, and it especially doesn't mean they can be stable long term.

Scarcity is a fact of nature. You cannot rationally distribute scarce things without knowing people's preferences, so you either need to continuously solve the economic knowledge problem (which requires a huge state apparatus, which will be taken over by a dictator), or a means of exchanging goods between people to better suit their preferences (at which point you have invented capitalism).
