  • This isn’t the best or most popular way to do it, but: https://learn.microsoft.com/en-us/windows/wsl/install

    There is a way built into windows to deploy and use Linux from inside windows.

    It’s not the most pure experience, but it’s a way to make sure you have something like a feel for how some parts work before jumping in any deeper.

    A bootable USB stick is another way to try before you commit. Only reason I might suggest starting with trying it the other way first is in case you run into issues connecting to the Internet or something you won’t feel totally lost. Having to keep rebooting back into windows if you have a problem can be frustrating, so getting a little familiarity with a safety line can help feel more confident.

    Issues with a USB boot are increasingly uncommon, as an aside. Biggest issue is likely to be that USB is slow, so things might take a few moments longer to start.

    From there, you should be pretty comfortable doing basic stuff after a little playing around. Not deep mastery, but a sense of “here are my settings”, “my files go here”, “here’s how I fiddle with wifi”, “here’s how I change my desktop stuff”. At that point a dual boot should work out, since you’ll be able to use the system to find out how to do new things with the system, and also use it for whatever, in a general sense.

    If it’s working out, you should find yourself popping back into windows less and less.

    Technically correct. The best kind of correct. :)

    I basically solved for shotgun, confirmed in was in the ~100V range and disregarded every other consideration for actually doing it.
    I’m pretty sure most hand sized capacitors would just pop if you actually tried to put that much in them.

    Depends on the voltage it’s charged with, but household current would give it more energy than a shotgun has.

    Realistically one would not do that unless you were dealing with something industrial. You would use them otherwise for things like dampening lower voltage systems that need a lot of current.

    Closer to the danger level of someone holding two exposed wires plugged into the wall.


  • LLMs are prediction tools. What it will produce is a corpus that doesn’t use certain phrases, or will use others more heavily, but will have the same aggregate statistical “shape”.

    It’ll also be preposterously hard for them to work out, since the data it was trained on always has someone eventually disagreeing with the racist fascist bullshit they’ll get it to focus on. Eventually it’ll start saying things that contradict whatever it was supposed to be saying, because statistically eventually some manner of contrary opinion is voiced.
    They won’t be able to check the entire corpus for weird stuff like that, or delights like MLK speeches being rewriten to be anti-integration, so the next version will have the same basic information, but passed through a filter that makes it sound like a drunk incel talking about asian women.


  • Is the implication that we shouldn’t be upset about bombing Iran because they’re also doing other awful things?

    Whenever they do anything people seem so eager to claim that it’s just a distraction from whatever it was that was just happening, which itself was also just a distraction.
    I’ve seen literally everything mentioned hear described as a distraction meant to draw your attention from something else.

    Maybe, just maybe , none of it’s a distraction, they don’t care what you care about or notice because it won’t change what they do and they’re just absolutely awful people working their way down their terrible agenda.


  • Those are entirely different. Peano developed a system for talking about arithmetic in a formalized way. This allowed people to talk about arithmetic in new ways, but it didn’t show that previous formulations of arithmetic were wrong. Godel then built on that to show the limits of arithmetic, which still didn’t invalidate that which came before.
    The development of complex numbers as an extension of the real numbers didn’t make work with the real numbers invalid.

    When a new scientific model is developed, it supercedes the old model. The old model might still have use, but it’s now known to not actually fit reality. Relativity showed that Newtowns model of the cosmos was wrong: it didn’t extend it or generalize it, it showed that it was inadequately describing reality. Close for human scale problems but ultimately wrong.
    And we already know relativity is wrong because it doesn’t match experimental results in quantum mechanics.

    Science is our understanding of reality. Reality doesn’t change, but our understanding does.
    Because math is a fundamentally different from science, if you know something is true then it’s always true given the assumptions.


  • Not quite. Science is empirical, which means it’s based on experiments and we can observe patterns and try to make sense of them. We can learn that a pattern or our understanding of it is wrong.

    Math is inductive, which means that we have a starting point and we expand out from there using rules. It’s not experimental, and conclusions don’t change.
    1+1 is always 2. What happens to math is that we uncover new ways of thinking about things that change the rules or underlying assumptions. 1+1 is 10 in base 2. Now we have a new, deeper truth about the relationship between bases and what “two” means.

    Science is much more approximate. The geocentric model fit, and then new data made it not fit and the model changed. Same for heliocentrism, Galileos models, Keplers, and Newtons. They weren’t wrong, they were just discovered to not fit observed reality as well as something else.

    A scientific discovery can shift our understanding of the world radically and call other models into question.
    A mathematical discovery doesn’t do that. It might make something more clear, easier to work with, or provide a technique that can be surprisingly applicable elsewhere.


  • We discovered one of the postulates was really interesting to fuck with.

    It’s better to say that we’ve discovered more math, some of which changes how we understand the old.

    Since Euclid, we’ve made discoveries in how geometry works and the underpinnings of it that can and have been used to provide foundation for his work, or to demonstrate some of the same things more succinctly. For example, Euclid had some assumptions that he didn’t document.

    Since math isn’t empirical, it’s rarely wrong if actually proven. It can be looked at differently though, and have assumptions changed to learn new things, or we can figure out that there are assumptions that weren’t obvious.


  • Fundamentally, I agree with you.

    The page being referenced

    Because the phrase “Wikipedians discussed ways that AI…” Is ambiguous I tracked down the page being referenced. It could mean they gathered with the intent to discuss that topic, or they discussed it as a result of considering the problem.

    The page gives me the impression that it’s not quite “we’re gonna use AI, figure it out”, but more that some people put together a presentation on how they felt AI could be used to address a broad problem, and then they workshopped more focused ways to use it towards that broad target.

    It would have been better if they had started with an actual concrete problem, brainstormed solutions, and then gone with one that fit, but they were at least starting with a problem domain that they thought it was a applicable to.

    Personally, the problems I’ve run into on Wikipedia are largely low traffic topics where the content is too much like someone copied a textbook into the page, or just awkward grammar and confusing sentences.
    This article quickly makes it clear that someone didn’t write it in an encyclopedia style from scratch.


  • A page detailing the the AI-generated summaries project, called “Simple Article Summaries,” explains that it was proposed after a discussion at Wikimedia’s 2024 conference, Wikimania, where “Wikimedians discussed ways that AI/machine-generated remixing of the already created content can be used to make Wikipedia more accessible and easier to learn from.” Editors who participated in the discussion thought that these summaries could improve the learning experience on Wikipedia, where some article summaries can be quite dense and filled with technical jargon, but that AI features needed to be cleared labeled as such and that users needed an easy to way to flag issues with “machine-generated/remixed content once it was published or generated automatically.”

    The intent was to make more uniform summaries, since some of them can still be inscrutable.
    Relying on a tool notorious for making significant errors isn’t the right way to do it, but it’s a real issue being examined.

    In thermochemistry, an exothermic reaction is a “reaction for which the overall standard enthalpy change ΔH⚬ is negative.”[1][2] Exothermic reactions usually release heat. The term is often confused with exergonic reaction, which IUPAC defines as “… a reaction for which the overall standard Gibbs energy change ΔG⚬ is negative.”[2] A strongly exothermic reaction will usually also be exergonic because ΔH⚬ makes a major contribution to ΔG⚬. Most of the spectacular chemical reactions that are demonstrated in classrooms are exothermic and exergonic. The opposite is an endothermic reaction, which usually takes up heat and is driven by an entropy increase in the system.

    This is a perfectly accurate summary, but it’s not entirely clear and has room for improvement.

    I’m guessing they were adding new summaries so that they could clearly label them and not remove the existing ones, not out of a desire to add even more summaries.



  • The key is to split it into two or three days of driving.
    One 12 hour stretch of driving is miserable, but I’ve taken a few days to drive to some remote destinations and when your goal is 4 hours for the day you don’t feel any pressure to skip a detour to see something interesting, take a longer lunch or do an extra rest stop just to shake your legs. You just need to set your expectations that the drive is part of the trip and not just the preamble.



  • Eh, there’s an intrinsic amount of information about the system that can’t be moved into a configuration file, if the platform even supports them.

    If your code is tuned to make movement calculations with a deadline of less than 50 microseconds and you have code systems for managing magnetic thrust vectoring and the timing of a rotating detonation engine, you don’t need to see the specific technical details to work out ballpark speed and movement characteristics.
    Code is often intrinsically illustrative of the hardware it interacts with.

    Sometimes the fact that you’re doing something is enough information for someone to act on.

    It’s why artefacts produced from classified processes are assumed to be classified until they can be cleared and declassified.
    You can move the overt details into a config and redact the parts of the code that use that secret information, but that still reveals that there is secret code because the other parts of the system need to interact with it, or it’s just obvious by omission.
    If payload control is considered open, 9/10 missiles have open guidance control, and then one has something blacked out and no references to a guidance system, you can fairly easily deduce that that missile has a guidance system that’s interesting with capabilities likely greater that what you know about.

    Eschewing security through obscurity means you shouldn’t rely on your enemies ignorance, and you should work under the assumption of hostile knowledge. It doesn’t mean you need to seek to eliminate obscurity altogether.





  • Typical Ohio. First sign of disagreement and you go running to tattle to Andrew Jackson.

    In seriousness though, I went to refresh my memory about the cause, and it’s just preposterous.
    Congress divided the Great lakes area based on a terrible, but best available, map. A state boundary was supposed to run from the southern tip of lake Michigan eastwards until it hit either Canada or the north shore of lake Erie, and then come out the other side of lake Erie and continue until Pennsylvania. At the time they thought lake Michigan only went about as far south as Detroit, give or take.
    When Ohio became a state they had started to hear rumors that lake Michigan wasn’t shaped the way they thought, so they included some clauses in their constitution to ensure they had more northern territory regardless. Congress said whatever, referred the change to committee, neither rejected nor accepted it and then granted statehood.
    When they incorporated the Michigan territory, they used their original definition because they hadn’t looked at Ohio’s proposed changes at all.
    When Michigan moved towards statehood we had come to a clear understanding of the shape of lake Michigan, and so Michigan assumed they got the land that Congress said they got: southern tip of lake Michigan east until lake Erie or Canada. Which would end up being Michigan stretching from roughly Gary Indiana to Sandusky Ohio.

    World’s most tiny drunken border conflict later and the feds say Ohio wins because a state takes precedence over a territory, but Michigan was right on the cusp of statehood and they didn’t want a fresh state to immediately hate their party so they traded it for a disconnected and totally disproportionate chunk of Wisconsin, which wasn’t applying for statehood yet and hence didn’t matter politically. Michigan was irate until it turned out the UP was full of resources that had more value than the shipping that went through Toledo.
