  • Subhuman lemmy posters: “We are spending way too much!!! $0.5m on scientific research!!! Outrageous!”

    Me: “Bro we spend billions killing children around the world who tf cares there are other places you should be concerned about budget.”

    Subhuman lemmy posters: “Errrm actually stfu stop bringing that up, we want to cut everything but that!”

    kys you people are freaks, this place is just as bad as reddit, entirely comprised of genocidal US ultranationalist sociopaths. I need to go to a forum that is not English-speaking.


  • Interesting you get downvoted for this when I mocked someone for saying the opposite who claimed that $0.5m was some enormous amount of money we shouldn’t be wasting, and I simply pointed out that we waste literally billions around the world on endless wars killing random people for now reason, so it is silly to come after small bean quantum computing if budgeting is your actual concern. People seemed to really hate me for saying that, or maybe it was because they just actually like wasting moneys on bombs to drop on children and so they want to cut everything but that.






  • i use one of those trackball mice with the ball on top. first time i tried it i never went back, no need to worry about having a proper surface or desk space for a mouse ever again. if you reach the side of your desk using an optical mouse, you have to pick the mouse up and move it all the way to the other side of the desk, while is a proper ball mouse (a good one without too much resistance) when you flick the ball it can continue spinning a bit even as you release it, so you can flick it to the side and then bend your wrist slightly to then flick it again, and the mouse cursor will just continue moving without stopping, which in games you can do this to have endless turning around, when turning is always stuttery on an optical mouse due to hitting the end of the desk. it takes a little bit to get used to, but at least a good one with limited resistance and a large ball, you can easily get just as accurate as an optical mouse as well. the only downside i find is that i do have to take the trackball out and clean it like the ones on the bottom.

    That’s not how political parties work, though. Political parties are largely ideological institutions, they exist first and foremost not to win elections but to propagate an ideology, and winning the election is just a sign that they succeeded in their goal of convincing people of their ideology, and so now enough people agree that it can take root in the state. When political parties lose, it’s very rare that they will interpret their loss as “we need to abandon all our values to match the opinion polls.” No, they interpret their loss as meaning they failed in their goal of convincing people of their values, and thus should change their strategy of their out-reach, not changing their whole ideological position.

    Democrats going against the rich elites would be an abandonment of their party’s values and everything they stand for. In most countries, if you dislike the ideology of a party, you vote for someone else. The party itself has no obligation to change its entire ideology for you, such a thing very rarely occurs. If that was the case, then every political party would all have the exact same position, just all copy/pastes of whatever the opinion polls say.

    I keep seeing all this bizarre rhetoric about how if the Democrats were “smart” they would just abandon their whole party’s platform and adopt some other platform, but this makes zero sense, because you have to consider motivation. Their motivation is not to just win the election, but to convince you of their ideology, and abandoning their ideology does not achieve this. Democrats are not stupid, they just don’t have the same motivations as you. Yes, they want to win, but they ultimately want to win on their platform, not on someone else’s platform.

    That’s how political parties work. They have a platform, and the platform is paramount. If a green party adopted all pro-coal and pro-oil lobby positions just to win an election, that would not be a “smart” decision for them, because, even if it leads to their victory, it still is an abandonment of their ideology. Democrats are unabashedly a pro-rich elite party, it should not be smart for them to become anti-elite, because it is not aligned with their motivations.

    Yes, it’s ultimately a cautionary tale as to why social democracy is unsustainable, as it is just the implementation of social policies while maintaining capitalist hegemony. There is no such thing as a benevolent oligarch. Capitalists have utilitarian reasons to implement pro-worker social policies, and it’s usually to reduce unrest or increase productivity. The moment those reasons no longer become relevant, they will begin to dismantle it. Much of western Europe in general right now is suffering from nonstop austerity for a long time now.

    Bell’s theorem demonstrates that you cannot have a deterministic theory that would also be Lorentz invariant, that is to say, compatible with special relativity and the speed of light limit. The speed of light limit is very well tested over and over again, and no one to this day has ever been able to construct even a single mathematical model that could even approximately reconstruct the predictions of quantum field theory in a way that is deterministic. That suggests that any deterministic theory would actually make quantifiably different predictions than quantum field theory, and yet we don’t have any evidence that its predictions are violated, and quantum field theory is verified to 12 decimal places of precision.

    I don’t really understand your point about the dice. If you have two “quantum” dice that are exactly the same, they are not guaranteed to land on the same thing, and that is precisely what it means to be nondeterministic, that even if all the initial conditions are the same, the outcome can be different. Yes, we cannot make the whole universe the same throughout the experiment, but to make sense of this, you cannot speak in vague philosophy but need to actually specify in mathematical terms what parts of the universe you think are determining the outcome, which, again, any attempt to specify such a thing would require contradicting the predictions of quantum field theory.

    My issue with your argument is that, whether or not you intended this or not, what you are undeniably arguing is that all our current physical theories are currently wrong and making the wrong predictions, and they need to be adjusted to make the right predictions, and you are basing this off of what is ultimately a philosophical criticism, i.e. that it is not deterministic and you think it should be, without even having a viable model of what this determinism would look like. It just seems far too speculative to me.

    Yes, you can always make the argument that “our old theories have been proven wrong before, like Newton’s gravity was replaced with Einstein’s gravity, so we shouldn’t put much stock into our current theories,” but I just find this unconvincing, as you can make this argument in literally any era, and thus it completely negates the possibility of using science to understand the properties of nature. Every scientific theory would have to always be interpreted as just something tentative that can’t tell us anything about nature, because it’s bound to be replaced later, and instead we’re just left arguing vague philosophy not based on anything empirical.

    I will readily admit that if I base my understanding of reality on our best physical sciences of the era, those can be overturned and I could be shown to be wrong. However, I still find it to be the most reasonable position as opposed to trying to “intuit” our way to an understanding of nature. The person who strongly defended the Newtonian picture of nature prior to Einstein was later shown to be wrong, yes, but he was still far more correct than the majority of those who insisted upon trying to derive an understanding of nature entirely from intuition/philosophy. I am with Heisenberg who argued that until we actually have any experimental evidence that violates the predictions of quantum field theory and can only be corrected with the introduction of hidden variables, then positing their existence is pointless metaphysical speculation, not derived from anything empirical.

    Ah yes, crying about “privilege” while you’re here demanding that people shouldn’t speak out against a literal modern day holocaust at the only time when they have the political power to make some sort of difference. Yeah, it’s totally those people who are “privileged” and not your white pasty ass who doesn’t have to worry about their extended family being slaughtered.



  • “Separation of powers” is an incredibly nonsensical concept. If we live in a democracy then the democratically elected legislature should have total power. The idea that unelected judicial branch can dictate policy is indeed anti-democratic, the judicial branch should be wholly subervient to the legislature. The same is true of the executive branch, the executive branch also should be wholly subservient to the legislature. Giving a single guy control over the whole freaking military and making the branch roughly independent is also entirely nonsensical. It has happened historically in the past in several countries that the executive just tells the military to attack the legislature and the country collapses into a dictatorship. This literally almost happened in South Korea literally today, although the president backed down at last moment. Any country with separation of powers is already borderline a totalitarian dictatorship, since it just takes a single crazy executive to decide to pack the courts and disband the legislature solely for their own personal gain and the whole thing falls apart.

    It’s always funny seeing arguments like this as someone with a computer science education. A lot of people act like you can’t have anything complex unless some intelligent being deterministically writes a lot of if-else statements to implement it, which requires them to know and understand in detail what they are implementing at every step.

    But what people don’t realize is that this is not how it works at all, there are many problems that are just impractical to actually “know” how to solve yet we solve them all the time, such as voice recognition. Nobody in human history has ever written a bunch of if-else statements to be able to accurately translate someone’s voice to text, because it’s too complicated of a problem, no one on earth knows how it works.

    Yet, of course, your phone can do voice recognition just fine. That is because you can put together a generic class of algorithms which find solutions to problems on their own, without you even understanding how to solve problem. These algorithms are known as metaheuristics. Metaheuristics fundamentally cannot be deterministic, they require random noise to work properly, because something that is deterministic will always greedily go in the direction of a more correct solution, and will never explore more incorrect solutions, whereby an even better solution may be beyond the horizon of many incorrect ones. They also do have to be somewhat deterministic as well, because you need some greed or else the random exploration would be aimless.

    A simple example of a metaheuristic is that of annealing. If you want to strengthen a sword, you can heat up the metal really hot and let it slowly cool. While it’s really hot, the atoms in the sword will randomly explore different configurations, and as it cools, they will explore less and less, and the overall process leads them to finding rather optimal configurations that strengthen the crystaline structure of the metal.

    This simple process can actually be applied generally to solve pretty much any problem. For example, if you are trying to figure out the optimal route to deliver packages, you can simulate this annealing process but rather than atoms searching for an optimal crystaline structure, you have different orders of stops on a graph searching for the shortest path. The “temperature” would be a variable that represents how much random exploration you are willing to accept, i.e. if you alter the configuration and it’s worse, how much worse does it have to be for you to not accept it. A higher temperature would accept worse solutions, at very low temperatures you would only accept solutions that improve upon the route.

    I once implemented this algorithm to solve sudoku puzzles and it was very quick at doing so, and the funny thing is, I’ve never even played sudoku before! I do not know how to efficiently solve a sudoku puzzle, I’ve honestly never even solved one by hand, but with sudoku it is very easy to verify whether or not a solution is correct even if you have no idea how to find the solution and even if finding it is very difficult, verifying it is trivially easy. So all I had to do is right the annealing algorithm so that the greedy aspect is based on verifying how many rows/columns are correct, and the exploration part is just randomly moving numbers around.

    There are tons of metaheuristic algorithms, and much of them we learn from nature, like annealing, however, there’s also genetic algorithms. The random exploration is done through random mutations through each generation, but the deterministic and greedy aspect of it is the fact that only the most optimal generations are chosen to produce the next generation. This is also a generic algorithm that can be applied to solve any problem. You can see a person here who uses a genetic algorithm to teach a computer how to fly a plane in a simulation.

    Modern AI is based on neural networks, which the greedy aspect of them is something called backpropagation, although this on its own is not a metaheuristic, but modern AI tech arguably qualifies because it does not actually work until you introduce random exploration like a method known as drop out whereby you randomly remove neurons during training to encourage the neural network to not overfit. Backpropagation+dropout forms a kind of metaheuristic with both a greedy and exploratory aspect to it, and can be used to solve just about any generic problem. (Technically, ANNs are just function-approximators, so if you want to think of it as a metaheuristic, the full metaheuristic would have to include all the steps of creating, training, and then applying the ANN in practice, as a metaheuristic is a list of steps to solve any generic problem, whereas an ANN on its own is just a function-approximator.)

    Indeed, that’s how we get phones to recognize speech and convert it to text. Nobody sat down and wrote a bunch of if-else statements to translate speech into text. Rather, we took a generic nature-inspired algorithm that can produce solutions for any problem, and just applied it to speech recognition, and kept increasing the amount of compute until it could solve the problem on its own. Once it solves it, the solution it spits out is kind of a black box. You can put in speech as an input, and it gives you text as an output, but nobody really even knows fully what is going on in between.

    People often act like somehow computers could not solve problems unless humans could also solve them, but computers already have solved millions of problems which not only has no human ever solved but no human can even possibly understand the solution the computer spits out. All we know from studying nature is that there are clever ways to combine random exploration and deterministic greed to form processes which can solve any arbitrary problem given enough time and resources, so we just implement those processes into computers and then keep throwing more time and resources at it until it spits out an answer.

    We already understand how nature can produce complex things without anyone “knowing” how it works, because we do that all the time already! You do not need a sentient being to tell the beetle how to evolve to fit into its environment. There is random exploration caused by genetic mutations, but also a deterministic greedy aspect caused by “survival of the fittest.” This causes living organisms to gradually develop over many generations to something fit for its environment. And life has had plenty of time and resources to become more suited to its environment, life has been evolving for billions of years, with the whole resources of the planet earth and the sun.


  • No, the point is that bacteria can produce toxins in between a company packaging a product and a person receiving it and then boiling it themselves. Companies have to kill the bacteria prior to shipping it. It’s similar to canned foods for example, they put it in the can then heat up the can to kill the bacteria, then ship it, so it shouldn’t have any harmful bacteria in there to begin with.

    Good. That’s when Democrats should be criticized the most, because that is the only time you have the power to exercise any leverage over them. Why would you refuse to criticize them when you actually have a tiny bit of leverage and wait until you have no power at all and your criticism is completely irrelevant and will be ignored? That is just someone who wants to complain but doesn’t actually want anything to change.
