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?

>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?


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



>>5894 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 >>5894 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.

Do we need a leftist Luke Smith?

hahahahahah the absolute state of leftypol


he just does whatever /g/ thinks is cool. nothing about him is intelligent or groundbreaking.


Go listen to some of the podcasts he's done, he's some kind of Tradchrist-monarchist freak living on land he bought using a gift from a rich family member and memeing about technology he doesn't really understand (I'll make my dotfiles reference the regular user account as SU so I never have to enter a password, this is a good idea lmao) to idiots that think being cool is hipster software + edgy jokes

Literally a soyboi living off of daddy's money and youtube bucks larping as ted, could you be more pathetic?


Potentially. What does the left Luke Smith (LLS) do differently?


also flirting with antisemitism

Mozilla shoots itself in the foot again to please its overlords at Google.

>I came across this video recently, in which Mozilla add-on developers talk about the implementation of the new "DeclarativeNetRequest" feature that Google intends to use in order to replace the current "block WebRequest" used in Manifest V2 by pretty much any content blocker worth of it's name. The video is only 3 weeks old: https://www.youtube.com/watch?v=tpDFS-GUytg

>To summarize the important bit of the video, Mozilla is planning to adopt the new functionality without replacing the current one, essentially to ensure compatibility between add-ons in Chrome and Firefox while also maintaining the content blocker functionality.
>However they are very careful to always say, wether in this video or in the corresponding blog posts, that they will support blocking WebRequest "for now", or "we don't have any IMMEDIATE plans to remove content blocking capabilities" which concerns me, because they are definitely going to implement DNR in the future, even if only at browser start up at first.
>The fact that they don't give us a definitive answer regarding content blocking features is a big concern. Surfing the web without UBO is…unthinkable at this point.

Just imagine if they had done this shit while they were the underdog to Internet Explorer.


they havent done anything yet


False, they've done A LOT of dumb shit over the years.

The headline made me think they could do all that just by you carrying a smartphone but it's an analysis of heavy smartphone use. Not that that's much better.

Wait so if I'm a poorfag who can't afford a fancy phone that supports an open source OS buying a used iphone is better than getting stock android shit?


>used iphone
only if you want apple to kill your device performance with a firmware update
see https://edition.cnn.com/2020/07/14/tech/apple-slow-iphone-settlement-payouts/index.html


Eh, I only use my phone for calling and whatsapp (thanks to normies and my boss).


buying a cheap android and installing replicant on it is better than both of those options.


Doesn't it suffer from the same issue as Graphene i.e. it's supported in very few devices that are hard to find and/or expensive?
