  • I torrented and seeded many torrents (its still seeding right now) and it can do at least 2 (havent tried more) jellyfin streams at once as long as I disable server side transcoding to reserve resources. I had the full arr suite of apps running along with ombi (gonna move to jellyseer, but imo ombi used too much ram on my 4GB laptop to be something I kept running). Is it perfect? No, it has quirks that will come up now and again but can I really complain when getting now 16 years of use out of a laptop I never thought I’d touch again once I built my desktop?

    Edit: oh be aware, if you’re using old hardware, DO NOT use the newest versions of things like Linux mint, it possibly won’t have drivers that works for really old hardware (like wifi card, Lan card, etc.) and it won’t be easily apparent sometimes. I solved this with a friend who had the same laptop as me but couldn’t get internet once installing mint. It turns out he used a newer version of mint that did not have a way to support his wifi card and installing and older version solved it



  • Yes, in a sense. It technically isn’t vibrating them, but rapidly spinning them due to the constantly changing magnetic field (produced by the magnetron).

    Since water has a dipole moment (one side of the molecule experiences a slight positive charge, while one side experiences a slight negative charge) it will react to changes in an electric field just like a magnet would

    Edit: I’d also like to add this is not specific to water. Some fats and other food material also undergoes that rotation, and the same concept (with different frequencies and wavelengths) is used in industrial processes all the time to quickly, and efficiently heat materials

    Completely fair point, that I do not think I have the knowledge to speak on. On the Trigonometry Wikipedia page, he pops up a few times, and many trig identities are known as pythagorean identities. Perhaps its not fully trig, but was used as a basis to help discover trig? Without having the understanding pythagorus gave mathematicians regarding triangles, I would think it would be pretty hard to begin developing deeper math regarding said triangles

    There will be those that do and dont get the “nitty gritty” of the theory side of the math. Those people sometimes become math majors. Normal people (joking, dont be mad math majors), need more than simply the theory side of the math and actually need to see/perform the application side of things. I never once “understood” the lesson in math class when we go over the equations with variables only. I only truly began to learn the material and be able to use it once we got to the example problems. We would do multiple in class and then I would understand how to literally go through the problem and perform the math that was expected of me on the homework, and subsequently the test. There is tons of stuff i know how to use in math, but by no means understand WHY it came to be, or HOW its works for the realm of mathematics. I wanna know how this math can help me solve real life problems, problems I will face in industry, or even just a cool way to apply math in the real world. Not how it will be used in research to find new types of math we wont be able to apply for 70 years.

    It was pretty funny being in calculus in college. I was in a class with mostly engineers who were also taking the exact same weed out courses, and nearly every day after the professor would finish showing us the theory side of the lesson, hands would shoot up and the question of, “What application does this have in real life or engineering? Like, how will I actually use this?” always got asked. So not “loving” the theory is by no means uncommon (we all wished for an application focused version of the class to exist, for people like stem students who are not into the math theory lol), but I still see the value in having it presented so that you can have a more foundational understanding instead simply going through the motions

    The reason they drill it in to the extent that they do is so that you have a foundational understanding of the underlying math on which to build new knowledge. If you show up in calc 1 in college without remembering even the basic concepts you were previously taught in things like trig…that can really bite you in the ass. My teacher LOVED pulling out classic substitutions for Secant, Cosecant, and cotangent (No, i didnt outright remember them from Trig, but I had seen them, and that made refreshing much easier). Also these concepts then form the basis of many other fields such as physics (electricity/magnetism, kinetic motion, optics, etc.), chemistry (quantum, MO theory, and things relating to the physics side of why chemistry occurs), and many of the graphing concepts used in engineering/stem only make sense if you have the foundational understanding of what integration/derivation are. Those stem from understanding how to graph complex functions by hand (like we did in trig) so that when you are doing it later with assistance, you still GRASP what is going on.

    Yes its not perfect, and yes for people who never need that later in life it can suck. However, I would make the argument it is better to have more of your population educated to a higher standard than what is needed in daily life, than to only give that to those who are aware enough at a young age to actively seek said education

    A^2 + B^2 = C^2 is known as the Pythagorean theorem. This theorem explains the proportionality of the 3 sides of a right triangle (a triangle with 1 corner angle = 90 degrees). If you know the length of 2 sides (in his example, the wall beams) you can find out the length of the third (in his example, this would be the supporting strut spanning the beams that meet at a 90 degree angle). If their example is explaining a beam that spans the room from 1 corner to the other, you still use this formula as a rectangle is 2 right triangles that meet along their hypotenuse (the longest leg of a right triangle, or the length you are solving for in this problem). The 2 known sides are the length/width of the room, and you solve for the 3rd side, your diagonal beam


  • You would use materials that perform completely fine at those temps. This could be anything from high nickel alloy steel, to Inconel, to an HEA (high entropy alloy). You can even do high heat resistant metals with ceramic coatings on the inside for protection if creating a passivation layer is too difficult for the application or the exposure environment does not allow for one to form.

    There is an entire subsection of engineering studies focused on purely coaxing specific properties out of a material or developing materials to custom suit extreme applications, known as material science. They generally work very closely with chemical engineers (my background) and metallurgists in order to manufacture the designed product in either batch form, or in continuous fashion.

    I work in a steel mill and we have Inconel furnace rolls that hang out in 1600 F heat 24/7 and are rated (iirc) to ~2300F max operation temp. For reference medium carbon steel melts between 2600 and 2800F, and loses a lot of its mechanical strength well before 2300F (I am trying to find a stress strain curve for carbon steel over multiple temperatures for reference. I will update if I find one)

    Edit: Okay so I found one that does show what I am trying to convey. As you can see, the higher the temperature of the sample material, the lower the yield strength. Example: the 100C sample was strained to >25% before failure, while the 700C sample began to plastically deform (fail) before 10% strain. Take note of the second link, all the test temperatures are MUCH higher than any of the carbon steel samples

  • The issue in my eyes, and my number one complaint with this massive E.V. push (for many years now) is the insane environmental impact of lithium mining and the very short termed planning of just going hard on batteries (without spending more time and money on better battery tech [Toyota actually has that new solid state battery I’m very hopeful for, and we’ve been working on polymer batteries for decades]) we will waste a very precious earth material we WILL NEED in the future, and you never ever hear any of the politicians or CEOs talk about how dirty lithium mining and processing is because almost all of it happens outside the countries leading this push (thus, not their problem).

    Not saying we shouldn’t be moving away from ICE, it’s that I feel our current approach is incredibly short sighted, and will have far reaching impacts into future generations and I feel as though we may even cause more damage than help in our current approach



  • Actually a very fair point, and something that I do in fact find interesting is that it hasn’t breached FO4’s numbers. That game burned me so fucking hard lol. I bought that pile of shit at full price (last game I ever purchased at launch), and it ran SOOOOOO bad. Like less than 20 fps in any city bad. I tried to push through the framerate/bugs to get to the good and for me it just never came. I dropped that game after 1 playthrough and I have 0 desire at all to ever pick it up again. I have replayed skyrim (heavily modded at this point) and FO:NV (FO3 didnt work right on my W10 machine, i wonder if it works now with W11 and compatibility mode. I would replay that for sure), but I think with FO4 the charm had worn off. Playing a game that felt like oblivion [Not in a literal sense, but in the “its a bethesda RPG” sense] (with shitty quest writing) in the modern day at sub 20 fps for the price of $60 was one hell of a wakeup call.

    So all of that is to say, I find it surprising that their new flagship has not beaten FO4’s numbers. Perhaps they burned a lot more people than just me?


  • I do not know a single person IRL who has purchased this game (across multiple platforms). We all played and love to this day, Skyrim, FO3, FO:NV (my friends like FO4, it wasn’t for me personally, I found the story incredibly boring…the dogshit performance on release also never helped). So I am wondering what their gamepass numbers are vs. full purchases. Steam (the numbers cited in the article) would be purchases, but I would be interested one day to see the split of gamepass to purchase users


  • Anyone I know who left our troop, did so early after transitioning from cub scouts to boy scouts. Most had other commitments that required most of their time (sports mostly), or they didn’t find it “cool”. I didn’t care if it was “cool” at school or not so that point never bothered me. I managed playing 2 year round sports along with scouts and clubs, but totally understand not wanting to make that commitment and deciding to drop scouts. I loved the camping trips, cool merit badges, and high adventure opportunities it provided (like Philmont Ranch).

    You seem to have a very different perception of scouting (which obviously could come from the way your troop functioned vs. how my troop did for example), but my point is that you shouldn’t paint things with a broad brush. Again, I don’t share any of these same sentiments with you, but you speak like it’s absolute fact or that you know all intricacies of the situation. You simply do not, nor do I. I am sorry you had a poor experience.

    To your last point. I just texted 2 people who left my troop (we are still friends) and brought forward what you said. Only 1 has responded so far and said “LOL, it had nothing to do with “facism” wtf. I just didn’t really love it so I didn’t want to keep putting time into it.” So again to my point of not painting things with a broad brush…not everyone shares your experience of “the young fascists club”. In general, sweeping generalizations result in indefensible positions. It’s easy to find flaw in absolutist statements about large groups


  • I’m not sure what troop you were in, but nobody I know had an experience like that in scouts. I loved scouts and highly suggest people get into it. Without scouting I would have never done many awesome things, and I straight up never would have gotten the chance to get into certain hobbies like snowboarding (my family does not ski), without taking merit badges like the snow sports merit badge. I learned how to scuba dive, I learned blacksmithing (awesome merit badge), it helped fuel my love of chemistry, and so SOOO much more. I’m not saying it’s all fine and dandy, there are bad people out there. However, painting scouts with a broad brush (or painting anything with a broad brush) is just wrong. It’s not representative of the entire group, nor of everyone’s experience with said group.

    I would say scouting significantly built my leadership skills, I attended multiple leadership conferences and trainings, and my eagle scout award is a talking point in every interview. Along with many of the life long friends I made along the way, I highly recommend scouting to young children. You will be shocked the cool opportunities it can provide.

    Finally, I’m not in any way sure what was fascist about anything we did in scouting? Outside of being respectful when performing flag ceremonies, very little national anything came up unless we took a trip to a military base to see refueling planes for example. I’d assume this highly depends on the troop and its leaders, but again this is not an across the board scouting thing. Every troop can be wildly different from the next as long as their bylaws fit within thr BSA rules
