is quantum computing legit or is it all hype? Comrade 12/01/2020 (Tue) 02:50:40 No. 6621 [Reply]
how come it seems like no progress has been made? we keep hearing about research but it seems like we never get to see any results. what gives? what even is quantum computing anyway?

>>6631 >superposition, or the ability to operate on many qubits at the same time instead of consecutively on bits as it is in computers so what does that mean from a programming point of view? in what specific way does that effect the time complexity of an algorithm?
>>6641 Imagine a rat trying to find a way out of a maze. The classical way, the rat has to go all the way down a path, and only after hitting a dead end can it then try checking another path. A quantum rat can go down every path simultaneously, solving the maze much faster
>>6641 >>6642 is a pretty good explanation tbh. it's also why right now google, ibm, et al. are measuring their successes in building a quantum computer by its quantum volume, a number that takes into account both amount of qubits and its effective error rate, because every qubit that is added and can operate relatively error free theoretically increases the capability to operate on data exponentially by allowing larger data structures. then all you need is an actual algorithm that can take advantage of this capability in a way that makes it more efficient than classical computers. as >>6642 said pathfinding is one example of a problem that might benefit from this, so in complexity terms if we take A* (which worst case can get polynomial cost in bounded tree) and compare it to say a quantum binary tree search then, assuming there are enough qubits with a negligible error rate, you would get at least an exponential speed up. pathfinding of course is fairly unique here because its memory bounded first and foremost, and every attempt at a quantum pathfinding algorithm i know of currently uses a qubit per pathing decision for example, so on large enough paths this really does exhaust capabilities of current quantum computers if you take into account that the "best" quantum computers (google, ibm) at the moment have around 50 qubits. ibm is "planning for a 1000 qubit computer by 2023" but right now this is just big words. but to generalise it: if you are working on an algorithm that requires finding the correct state in a large state space, then quantum will in general offer (usually) an exponential kind of speed up there. and this is before we get to unique solutions that use entanglement like https://en.wikipedia.org/wiki/Shor%27s_algorithm
Can't wait for quantum computers to decrypt all logged tor traffic that passed through CIA-owned nodes.
Haskell and Ocaml are the only programming languages I use.

Is there something like HackerNews but not infested by Silly Valley's libertarian STEMlords and VC-bootlicking hustlers?

>>4757 I agree about hacker news. I'd say they are a mix of steven pinker (neo-)liberals and "rational" libertarians. Interestingly, I saw a comment on hacker news saying that "if I wanted to know that vaccines cause autism, [other fake conspiracies theories], I'd go to reddit, not here", implying reddit is a schizo asylum. Interesting because I assumed reddit was mostly a liberal le I fucking love science circle jerk. I mentioned it before, https://lobste.rs is the only tech news site I can tolerate, besides the subreddits of specific technology, eg r/haskell, etc. Tech, as it exists now, is tied to politics and to capitalism more generally, you can't really escape that, so you'll occasionally see bad takes. I saw that lemmy shit but I'm just so burnt from reddit that seeing the interface gave me PTSD.

We need to make bunkerchan browseable on smartphones. Clover was really comfy for browsing 8/leftypol/. Any Comrade willing to help implementing the Lynxchan API to Clover/Kuroba?

Repositories for references:


Currently they support only the Vichan API, but implementing Lynxchan API shouldn't be too hard.

kuroba was a fork of clover kuroba-ex is a fork of kuroba https://github.com/K1rakishou/Kuroba-Experimental by lines of code kuroba-ex is the smalles and also is mostly rewritten in kotlin, so there is that Kuroba-ex is the app that you want

>>5962 Does this support bunkerchan? Cause i can't find it on the app.
>>5987 no, thats the poin, lets add support to it in kuroba-ex
>>6603 Concurred. I'd contribute, but I need to learn Kotlin and the Android SDK first.

Google violated US labor laws by spying on workers who were organizing employee protests, then firing two of them, according to a complaint filed by the National Labor Relations Board (NLRB) today. Several other employees were fired in the wake of the protests, but the NLRB found that only the terminations of Berland and Spiers violated labor laws. https://www.theverge.com/2020/12/2/22047383/google-spied-workers-before-firing-labor-complaint

>>6706 It's kind of telling that they don't use this motto anymore. Now it's 'Do the right thing', and what this 'right thing' is up to anyone's guess.
>>6706 It's "don't be evil". I.e., perfectly fine to do evil as long as you keep your image clean.
