why is maths as a school subject nothing but difficult number tricks with no practical application? physics has equations that are both piss easy and give you answers you can use. fuck educational maths

The actual topics to cover will largely depend on what you want to get out of it. Since you mentioned ASCII, I assume you are interested in the actual representations used by computers and not just the numeral systems in mathematics. I'm sure there are plenty of textbooks that cover these things but I can't recommend any because I learned these stuff by attending lectures in university.

I would cover at least these topics:
- Boolean algebra, maybe a little digital circuits
- Numeral systems (binary, octal, decimal, hexadecimal)
- Bitwise operations
- Number representations (BCD, sign-magnitude, one's complement, two's complement, floating point)
- Memory, endianness
- Arbitrary precision numbers (maybe?)
- Character encodings (ASCII, ISO/IEC 8859, Unicode)
- Maybe some simple image format like something from netpbm? Or some other example of how other things are represented in computers. 3D models, audio? idk

I'm sure I missed something, hopefully other anons will insult me for it,

"current text generation models carry with them the seeds for worldwide human extinction and we need to act accordingly" is a massively strong claim that is entirely hypothetical and carries zero evidence to back it up. It was more believable to say that nuclear weapons would cause a human extinction event and it still didn't happen. Why does anyone take these clowns seriously

Well no, if someone has physical access to your machine always assume the worst. Encrypting like >>22332 says will only keep your data safe but they can still flash whatever they want on the machine.

Afaik once you go coreboot you can also flash internally which means anyone with a modified USB flash could easily change it too.

Remember to constantly randomize your MAC address.

 No.22255

randomizing your MAC address doesn't do shit unless you're concerned about the local network you're on. when packets get NAT'ed they don't preserve information about the MAC address on the local network because otherwise that would cause all sorts of problems. MAC addresses are only meaningful on a local network because iirc they're randomized and also dependent on the hardware you're using, so if every single MAC address of every device in the world was being sent around on the internet, there would be collisions all the time.

Also is it true that from Windows 10 until onwards (Windows 11), you don't need install any third-party or additional antivirus?

I mean Windows has nothing exclusive anymore, so I don't get the point in trying it pretend it's still easy to use past Windows 7. NixOS with KDE is easier to teach to kids and old people than Windows 11 unless you want more flexibility than windows would ever non-trivially provide in the first place.

That said, ClamWin was great back when I used to use Windows.

Canada’s favorite coffee chain was covertly data mining the shit out of people who just wanted cheap coffee, and they got outed by the government, then concluded tim hortons was basically being evil then was like “oh well can’t punish them".

>The Tim Hortons app used location data to infer where users lived, worked, and whether they were travelling. It generated an “event” every time users entered and left their homes, entered and exited their office, or travelled.

it's a good feature, you can pre-order your food and only go there to pick it up

more broadly, it's crazy how inefficient the food sector is under capitalism. food is the archetypal economy of scale, cooking at home shouldn't be cheaper than eating outside, there shouldn't be a kitchen in every house

>cooking at home shouldn't be cheaper than eating outside, there shouldn't be a kitchen in every house
Those are two separate issues. Why it's more expensive to eat outside is because the restaurant has to pay salaries to cooks and waiters, rent, taxes, licensing fees, equipment, etc.

No, there shouldn't be a kitchen in every house. People should have a communal kitchen in the building, and then people from that building have to be paid to work in the communal kitchen. It shouldn't be a free-for-all, the communal kitchen should be run like a restaurant. People can have a kitchenette at home to warm up things, make tea, etc.

Just found out about "invention clauses". In the US there are about 10 states which have 3 conditions: they own everything you name that was made on company time, using company equipment, or using trade secrets taught to you by the company.
Every other state does not include any conditions. They can claim everything you make, even if it's completely unrelated to your job. YouTube videos? Tutorials? Game streaming? A web comic? Literally anything. It's theirs.
They don't even have to make exemptions for collaborative work. They can take a portion of anything you contribute to if they want.

These laws completely ignores computer history. Workers walking out of Fairchild Semiconductor is how we got Intel, AMD and Zilog. Same with workers walking out of Motorola giving us MOS Technology. Meaning if the laws existed in the 1970s the PC would never have been invented in the USA as the military industrial complex had no interest in it and they employed all the engineers thus it would have had the intellectual property to the tech behind the PC and did nothing with it as DARPA didn't ask them to make one. Then you had Commodore and Atari swap a chunk of their engineers when Jack Tramiel bought Atari and when Commodore bought Amiga (that was engineers the left Atari prior) which would have been a IP nightmare.
