Yeah, I lived through the early "plug and pray" days.

And for some damn reason, printers seem to still be stuck in that age. My most upvoted post on ELI5 yet was me expounding upon the sorry state of the printing subsystem in Windows.

So your new games could be programmed to speak to the windows audio subsystem, which would speak to the sound card using drivers made by the sound card manufacturer, and these systems would keep track of the IRQs and DMAs and everything. Before that, the DOS games had to know how to speak directly to every sound card they wanted to support. There were a few standards, and not that many sound cards overall, but PnP eventually enabled a very wide range of devices that all mostly just worked.

It has a tiny electronic chip inside, and a coil made from very thin copper wire. The readers emit a high frequency magnetic field which induces enough power in the coil to turn on the chip. The chip and reader then communicate briefly, and the backend computer system can read the card ID, see that it's linked to you, and which privileges you have.

Edit: it's called NFC, for near-field communication. You can Google it to learn more.

You can probably see the circuitry if you hold the card up to a very strong light source, such as the lens of a projector.

Welcome to the wonderful world where us non-US keyboard layout users have been living for decades:

The game says, press "[". Sometimes I can press the key where "[" is on an US keyboard. Sometimes I can type "[" by pressing AltGr+8 in my language. Sometimes neither works (because the game doesn't know about AltGr, and I interprets it as "right alt") and I'm just unable to use this particular control.

Probably. It's why I learned English in school, despite living in Norway. But easy access to every part of the world is only a few decades old, and the internet is only a tiny part, or no part at all, of everyone's world as of yet. We still mostly want to talk to people in the real world, where geographical barriers have helped languages diverge for millennia. This is not quickly undone, even if people would want to.

Reflexes are controlled by local nerves and muscles. Some biochemistry is controlled by hormones made by glands, which affect how cells behave. Some is controlled only by the cells themselves.

Instincts, emotions, thoughts, memory, muscle memory, all voluntary movement is controlled by the brain.

We have a complex stack of control mechanisms. Intellect on top of emotions on top of instincts on top of reflexes on top of autonomous processes (which are layered too). The lower you go the less control you have and the more primitive the capabilities are. Reflexes and below don't even involve the brain.

While instincts are mostly concerned with immediate survival of the individual and the continuation of the species, most interpersonal, society-forming behavior is regulated by emotion. A lot of our identity lies there - belonging, love, likes and dislikes, connection, who we're comfortable with, who we open up to, but also hate, revenge and callousness.

That was from memory, but when I google it I find 1 out of 80000 instead.

Curiously I don't find a good source, only almost the exact same sentence repeated over and over, with slight variations, and the same weird grammatical issue/quirk.

This is the sentence: "Apples do not come true from seed. Actually about 1 in every 80,000 apple trees grown from seed is quality factors good enough to even be considered for evaluation."

With software which speaks to hardware. Let's say your program says PRINT "a" The program will send the ASCII code for "a" to the operating system, saying this is to be printed. The operating system will look up the pattern of pixels for "a" in a font file, and send it to the video card. The video card will store it in the frame buffer, which is then repeatedly read and sent to the screen, which will decode the pixel data to decide which dots of red, green and blue should be illuminated.

This is a bit simplified, because i don't actually know any of this in detail, but it shows the principle.

The great thing is that all the links in the chain only need to understand its immediate neighbors. The screen doesn't need to understand a frame buffer, or an OS, it just needs to translate a video signal to a screen image. And the programmer doesn't need to know anything about how the screen works, just how to tell the computer to display something. This divides the immense complexity of modern computers into components that a team of engineers can comprehend.

Some diseases also jump species. Animals can give humans rabies, but humans generally don't pass it on. These often stick around in species that don't get sick, or don't get nearly as sick, as we do. And some can linger, for example anthrax which can sit around in soil for decades, just doing nothing.

You wrote what I was going to, except faster and better.

If you don't wear shoes indoors, floor temperature and heat conductivity also matters. A carpet feels warmer than wood, which fells warmer than vinyl on concrete, which fells warmer than tile, even when they're all at the exact same temperature.
