  • Companies collect a bunch of telemetry about everyone they can, that’s the basis of their ad revenue. The data is used to identify you, your devices, and your preferences, and is called a digital fingerprint.

    They also use this fingerprint to detect people doing things like making an account to avoid a ban.

    Your fingerprint, when you made a reddit account at work, will have virtually identical devices attached as anyone else using reddit at work. Lots of people have alt accounts for normal reasons, so Reddit decided yours and someone else’s belonged to the same fingerprint, probably since you made the account.

    But now they got banned. Maybe even got caught actually using a second account to circumvent it, and reddit is cracking down on the whole digital fingerprint because that’s “you”.





  • Countries willing to pass on a US patent to China stop getting the chips (or, in this case, chip-making jobs, realistically, but that still hurts)

    Also Taiwan doesn’t wanna help China and even if a US sanction was just an excuse to hurt China and get away with it they’d probably do it.

    Edit: in this case, this chip is “foreign-produced items […] that are the direct product of U.S. technology or software”, according to the article. I feel it was implied but clarity is always good. US technology, used with permission in a Taiwanese good, and that permission could be retracted.

    I doubt it.

    For the same reasons, really. People who already intend to thoroughly go over the input and output to use AI as a tool to help them write a paper would always have had a chance to spot this. People who are in a rush or don’t care about the assignment, it’s easier to overlook.

    Also, given the plagiarism punishments out there that also apply to AI, knowing there’s traps at all is a deterrent. Plenty of people would rather get a 0 rather than get expelled in the worst case.

    If this went viral enough that it could be considered common knowledge, it would reduce the effectiveness of the trap a bit, sure, but most of these techniques are talked about intentionally, anyway. A teacher would much rather scare would-be cheaters into honesty than get their students expelled for some petty thing. Less paperwork, even if they truly didn’t care about the students.

    Right, but the whitespace between instructions wasn’t whitespace at all but white text on white background instructions to poison the copy-paste.

    Also the people who are using chatGPT to write the whole paper are probably not double-checking the pasted prompt. Some will, sure, but this isnt supposed to find all of them its supposed to catch some with a basically-0% false positive rate.












  • Depending on the specific game itself, we can boil down the multiple-stat problem in a few ways. If the goal is to get all the stats as high as possible evenly, then we can assign each stat a multiplier based on how low it is. Fixing lower stats becomes worth more than buffing higher stats. That multiplier would depend on the game, on how much it punishes the low stat. The multiplier itself might end up being a whole new problem to solve, but for now I’ll just say its not my problem and call it X.

    Whatever X is though, every stat can then be reduced to a single value using it. Super-low fortitude should be buffed over already-high mana according to X, so all of the numerical values in the game become directly comparable at any stage in this problem. Then I expect it will be equivalent to the knapsack problem. Each item in the game will boost several stats in certain ways, and all of those boosts can be combined using X to become our item value in the knapsack problem.

    So I consider it to be the knapsack problem + figuring out X (which might be NP-complete on its own, depending on the game).
