  • 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.



  • Oh, I totally know there’s been a lot of politics in the Foss community and that some of the people are nasty, I’m just flabbergasted that someone would try to connect such disparate things.
    I can comprehend a Nazi Foss enthusiast having opinions on race and on window managers. It’s when they start having racist opinions on window managers that it all flies out the window. It’s like being opposed to copper plumbing because it’s too Norwegian.

    Just a case of seeing irrational people who act irrationally act irrationally in a new way and being shocked that the irrationality doesn’t follow a pattern or stay in topic.



  • 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.




  • The US has a water system effectively comparable to the ones across Europe, FYI. That includes lead levels, since it wasn’t just the US that used lead pipes.

    In most circumstances lead pipes are safe to replace with different materials as part of routine maintenance. It’s only very notable incidents where things go wrong that have driven a push for greater haste, since it highlighted the consequences of things going wrong.



  • 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.



  • 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.


  • Sure. I wouldn’t disqualify someone for being ambivalent towards what we’re working on, but the person who seems interested is gonna be better to work with.

    Likewise when looking for a place to work, if the tangibles are equivalent I’ll prefer the place with better intangibles.

    I’m not in HR or management, so I don’t care about cost effectiveness or productivity beyond “not screwing me over”. From that perspective, it’s generally nicer to work with someone who finds it interesting than with someone who doesn’t.

    There’s no point asking “why do you want to work here”, because the answer is obviously a combination of money and benefits, and how food and healthcare keeps you from being dead.
    I can’t fault an interviewer who’s clearly trying not to ask the obvious question and instead actually ask how the candidate feels about the work instead of disqualifying them for not volunteering the right answer.

    It’s not unreasonable for an employer to ask a candidate how they feel about the work anymore than it’s unreasonable for the candidate to ask about the working environment.


  • I actually kinda agree with both here.

    It sucks working with someone who is utterly disinterested in the work, if it’s anything above rote work.
    Asking the candidate what they found interesting about it is at least a basically fine idea. If they can’t answer when you ask, that actually is kinda concerning.
    Big difference between asking and expecting them to volunteer the information.

    At the same time, if the people interviewing you can’t even pretend to show basic conversational courtesy by asking some basic “what do you do for fun” style questions or anything that shows they’re gonna be interested in the person they’re looking to work with, that’s a major concern.



  • Yup. Even easier, since a lot of the part modeling tools used by professionals use file formats that other modeling tools speak. AutoCAD is so pervasive that everyone speaks their format.

    The trickiest part is inevitably the “are we knowingly giving people something that’s unsafe when 3d printed” that they need to do for liability.
    Basically everywhere there’s a degree of “as a manufacturer of hygiene products you should reasonably catch risks that consumers wouldn’t, and not provide them”.

    I’d bet there’s a handful of people putting together some nice and proper reports explaining that while skin flakes, oils and bacteria can get trapped in the layer gaps and lead to bacteria growth, reasonable cleaning would offset any possible issues. Basic ass covering.


  • Some people seem to be taking it a little more confrontationally than seems necessary.

    Think “let” as in “facilitate” rather than “permit”. A step stool let’s you reach a high shelf, but you don’t need to ask it for permission.

    They’re providing 3d models they’ve done basic quality control on for some components of some devices.

    It’s 100% a sales tactic to increase their perceived value by creating the impression that repairs will be easier and so the thing will last longer. It just happens to be that the easiest way to do that is to actually do it.
