I tried finding you something, it's surprisingly hard. These two look good. They are from here: https://home.csulb.edu/~hill/ee201/



thanks fren
some wikipedia references and articles are also good resources tho it's a shame such info is so spread out


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,


This looks sick, I wish I had an excuse to use it.

Remember when javascript only existed to make websites prettier?


No, and my first browser was text based. JS has always been about adding functionality.


I think you mean CSS


Not to defend js-fuckery but Math.max() and Math.min() make sense if you think of them as taking the sup/inf of the empty set


nah back then it was about crashing your browser


I have a feeling that "AI alignment problems" were just made up to make programmers feel better about their inability to solve any real problem. Please tell me how wrong I am.

All those assholes are some flavor of lesswrongoid rationalist neorreactionary.


AI is nowhere close to being real and there's much bigger issues. None of the stuff like AI art is anything approaching actual AI.


>AI alignment problems
marketing term, nothing to do with programming


oh yeah dude ai is so so soooooo powerful right now we need to contain it pass laws only let a select few control it because it could kill us all im not blowing it out of proportion so you inflate our stocks no im actually sooo scared aha

I have used coreboot before, but I got a laptop with a weird chip layout that is going to be difficult to coreboot. I found a few workarounds, but I am having trouble understanding them. Would anybody here be willing to help?

How do you prevent an evil maid attack after flashing coreboot on a machine?

inb4 you don't


that has to be one dedicated maid to bring along a flashing kit when she could just drug me and tie me up and tell me I've been a bad boy

when is framwork laptop getting coreboot support??


LUKS + store the key in flash drive/TPM


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.

You know what would actually be a useful AI? One that crawls through the text of the entire written works of an author, isolates each logical assertion that author makes, and cross-checks it against other logical assertions for contradictions, to see if that author ever contradicts themselves. Is such a thing possible using LLMs? Does such a thing already exist?

Do these two sentences contradict each other:
<The puppet did not fit into the box because it was too big.
<The puppet did not fit into the box because it was too small.
I'm firmly of the opinion that they describe the same situation. (AI-trolling sentence pairs like the above are called Winograd sentences.) How could I know, clearly I don't make a deduction based on grammar here. There is a lot of grammatical ambiguity in sentences with what "it" or "he" or "this" actually refers to. And not just these. Words like "house" or "tree" are not unique identifiers that refer to exactly one object, "Jon" can refer to two different guys in a story, "Robert" and "Anton" can refer to the same Mr Robert Anton Something.

People resolve the ambiguity by thinking about the situation described. In parsing a story about a woman pranking another woman, reasoning about avoiding self-harm, about not being surprised by what you did yourself, that is reasoning about intent and what sort of information different people have, can be necessary. Current AI is very flaky at this.


>isolates each logical assertion that author makes, and cross-checks it against other
authors, to build a database/network map of which authors agree, which disagree, and to what degree (strong agreement, weak agreement).


It's trivially easy to write a formal language with arbitrary tokens signifying assertions and checking for contradictions with a SAT solver or something. Translating a text into this form is thorny because most texts are written about the real world and unambiguously transcribing the real world to a formal language is almost impossible, so you can always go "well is this what the author really MEANT?"


>Is such a thing possible using LLMs?
No, they don't understand the actual content of the statements, only the linguistic characteristics of the words (being generous).


it probably already is possible if you just customize GPT's personality and guide it every time for each text

Remember to constantly randomize your MAC address.
7 posts omitted. Click reply to view.


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.


>it's just nice to be noticed.
Deus Ex moment.


Android already does this by default.


sounds good if i'm on a labby, but why would i do it if i'm on desktop


>Thinking any of this shit is going to protect you from the fbi.
If I was doing shit that I thought yhe feds would care about I would use TailsOS or something, but you probably can't even count on that.


Yeah I still using it, in fact anyone still kinda using it cuz we can't just abandon our normies facade.

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

I still can't move on into Linux. Cuz it's not even my laptop, but my parents.

Best advice is to run Windows in a Qubes OS virtual machine.


you should only use the built-in windows defender unless you like installing spyware that will make your computer run even slower


although obviously the better option is simply not using windows at all


File: 1699464042518.jpeg (432.64 KB, 1072x1556, 23661f380e41cfde.jpeg)

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.


>kids will want to learn a programming language just to use the package manager and install programs
You had a point until you mentioned that meme OS.

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 streamlines the process. If you already have the app it has your payment info and so on and you can order stuff before you get there or something. It's really unnecessary and a sign of how strapped for time and productivity-maxing society has become.


here's how to streamline the process: use cash


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

everything I eat tastes like shit because I'm not going to waste my time learning to cook, and I'm not going to waste money eating outside


>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
It was the same in the USSR


>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.
