    Isn’t it a lot more like a capitalist treadmill? Work hard to make number go up! It is in fact beatable in the sense that the number can’t actually go up forever, eventually the system crashes.




  • So how does generating a one time pad from mutually accessible data fit into this scheme. Is the pad the cipher or the key?

    If two people agreed that the pad would be the output of a particular pRNG given the 3rd paragraph of the second article on the third page of that day’s newspaper as a seed.

    The attack vector would be shortcomings in the pRNG I guess? Which could result in the possibility of some sort of statistical language attack?

    Or the attacker could guess the newspaper text & algorithm.


  • Neat, yeah Wikipedia says steam cipher approximate one time pads but can also be completely insecure.

    I think it would take one hell of an effort to crack, it would be like 3MB encryption right? Or if they guessed the scheme they could try all mp3s ever torrented XOR’ed in every possible combination.

    Idk I think there’s something workable there but I only having a casual knowledge

    Also I think OP wanted pen and paper so maybe use a book instead digital files.


  • I’m certainly not an expert.

    But could you generate pads from mutually accessible data sources?

    Like use hit_me_baby_one_more_time_not_a_virus.mp3 appended with a password, as a seed in a pseudo random number generating algorithm, then do the same thing with another data source, repeat however many times, then XOR the generated numbers together, and use the result as a pad?






  • Edit to add disclaimer: this is shitpost level math here guys, I’m just spitballing.

    It would definitely emit thermal radiation. if it was 99% efficient and the size of pluto’s orbit, around a star like the sun, and the energy was used to create matter, I think it would radiate the remaining energy as 0.009 W/m2 with a peak emission wavelength of 150micrometers. The James Webb telescope has infrared capabilities that max out at 28.5 micrometers so def not detectable.

    But probably a dyson sphere would be smaller than pluto’s orbit, which would greatly increase the apparent power, and shorten the wavelength. idk it’s all imaginary.

    I won’t subject you to my hand writing but I did (power of sun × 0.01)/(surface area of sphere with Pluto’s orbital radius) to get radiation intensity (0.009 W/m2). Then rearranged Stefan-Boltzmann law to solve for temperature (19.8K). Then used Wien’s Displacement Law to calculate the peak wavelength (1.5×10-4 m).

    Maybe I’ll run the numbers again with a martian orbit radius, and 50% efficiency.







  • Fair enough I get all that. My contention is that writing off commenters as shills and bots underestimates the size of the problem.

    I agree that the Kremlin targets the fabric of our society. But they have succeeded to the point that we can’t just cut off the affected parts. It’s too pervasive. We need to mend and reinforce the damaged fabric. Idk if you’re confident they’re shills/bots/trolls then I guess you’re right, but what if they’re just ignorant?


  • Just FYI it’s totally possible for non-shills/bots to support Russia. They can be real people just with different experiences, values and/or information diets than you.

    Like to me it’s pretty obvious who the bad guys in the war are (russia). But to a Belarusian it’s probably not so clear (in fact I’ve met a Belarusian that feels this way).

    Writing people off as shills/bots gives a false sense of security (not exactly the passing I want but close enough I guess)

    I think it’s much healthier to say something like “your head is so far up your ass it’s difficult to understand you”.
