Computers have daemons inside.

Normally I laugh at these as they have some merit, but fuck this one. The right end of the curve isn’t some Jedi understanding of things, it’s tech bros that think AI is alive and they want to enslave us.
Ok, but what with the magnetic flux?
i think it just means that once you optimize the hardware close to what physics allows, you have to consider all kinds of strange phenomena appearing. like, quantum physics, electrons tunneling around, the internal resistance value of the wire antenna, etc.
it's not just "logic gates", by far not. e.g. consider the magnetic flux in magnetic storage disks.
But what if we don't do that but instead optimize hardware and software for the tasks? Hackers run 3D games on microcontrollers...
We have 1.7 nm processes now. That's like 10 atoms of Si. Foundries are increasingly magic crystal forges
It would be better with a charge-carrier diffusion diagram, but your computer is also full of very strong magnetic fluxes, changing all the time and interacting with each other.
It appears they’re discussing electron flow, which causes a magnetic field
Otherwise known as “programmers.”
Seriously though we tricked metal into thinking with runes and lightning. That is magic.
well actually silicon is a semi-conductor. not entirely a metal.
Ok, we tricked stone into actually-not-thinking.
"Actually-not-thinking" is still overselling it. Computers don't think. They compute, which is really just doing calculations, and that is not as complex as it sounds. I've seen people make water do calculations. The number of calculations and the speed they can be performed makes it seem like magic.
No, but the wifi chips do. Even radio engineers who designed them will tell you they just tamed the elves, they don't really understand how radio engineering works.
Computers have voodoo goblins inside them with the personalities of extremely malevolent genies.
No, I don't agree.
Every single problem can be traced to a specific source.
What a lot of people (especially in IT) determine as a glitch, is just some unexpected change that they don't have the time/energy to deal with and can be solved by just rebooting.
Every single thing has a cause, even if the problem was a single particle of radiation from space that flipped a bit on a hard drive.
I've had the pleasure to work with some IT-guru that could solve every problem. They could see where this unexpected change came from and tell how to solve it so it wouldn't ever happen again. Except maybe those bit flips.
Bitflips are fun.
For a while, I managed a fleet of about 6500 iPod touch devices, and we would have random failures on devices where a simple re-image would solve the problem. I did a back of the napkin calculation, and our rate of those failures was almost exactly the expected cosmic radiation bitflip chance for the total surface area of all the storage chips in our devices.
larger structure sizes can help against spontaneous bit flips, i think. at the cost of consuming more energy for each calculation step.
Indeed, but smaller structures are less likely to get hit in the first place, it's a bit of a trade off.
Also, error correcting memory and storage are things, but at the end of the day, that is just more/larger structures, which is a roundabout way of saying you're correct.
No, not every problem can be traced to a specific cause. Sometimes the information required to do that has been lost (or never existed) and finding the root cause becomes impossible.
How would you prove some random radiation caused a bit flip to make an app crash without having equipment to detect it set up beforehand?
I once had a email that crashed the network card on a windows 2000 server. That was not fun to try and find the problem. After the 3rd occurrence the network card got binned
Reminds me of https://www.catb.org/jargon/html/magic-story.html
(I can't get that link to work right now. Maybe it's down. So here is the same story on the Wayback Machine.)
The 'more magic switch' is one of my favorite stories like that, right up there with the 500 mile email.
Midwit doesn't know about RDSEED, or RNDRRS . Every modern computer has a hardware random number generator built in (aka true random number generator). Since there's a hwrng bulit in, operations that depend on it aren't deterministic.
Not a magic elf though. Definitely more goblin.
Don't forget about "race conditions"!
I still remember the time a bug was fixed by adding a comment on a previously empty line
Computers are fucking weird.
Back in the dark ages of late 90s/early 00s computing, I figured out that I could reliably crash a computer with a c++ script that printed char 7 (system bell) in a while loop, but if I added a semicolon in the next line the system would be fine.
It was fun putting the first exe as the shortcut on lab computers, as people would be sooooooo confused when their computer spazzed out and beeped at them at an ever slowing cadence when they tried to open a normal application. Never bothered how to do it on dual core systems, because I couldn't be forked.
