    A few things about those UV tubes:

    I have very similar LED tubes that I bought at a regular shop here in Austria. It's very likely that they are sourced from the same company in China. My version even runs on 220 V, so I guess it's more "fun".
    Those power cords that you got (connector on one end, stripped wires on the other) also came with the tubes I bought. Those are needed if you want to hard-wire those tubes somehow. If you want to daisy chain several tubes together, there are specific connector cables with plugs on both ends. There are also end caps that should have come with the tubes you bought to cover the otherwise exposed mains voltage pins at the other side of the tube.
    What's also interesting is that the tubes in the video don't have any earth connection even though the connector could support it. My version does have a working earth connection.

    In theory, this is possible, but not worth it (due to cost and power losses). You also have to take into account that those devices usually need a lot of power, which means that a single phase circuit would need to handle a lot of current.
    If you have to rewire everything, keep in mind that there might be several ways of doing that depending on what the electrical code in your country specifies. Since this is a workshop, you could think about installing wall-mounted or ceiling-mounted conduits for the wires, which should be easier and less expensive than running everything inside the walls.

    I know, just an expression. I am aware that it is usually a capacitor or capacitor bank in most cases. I have also seen such a thing in combination with LC filters on one PCB.

    Again, this isn't how physics works. Inside a conductor are free electrons. When a magnet is brought near the conductor, the free electrons move within the conductor as the magnet moves closer. However the electrons stop moving as soon as the magnet stops moving, or when they reach the bounds of the conductor.
     
    To produce a constant flow of electrons, i.e. electric current, the magnet needs to move and the magnetic field needs to constantly change. 
     
    You can also look at it from a broader conservation of energy perspective. Energy out must equal energy in. If nothing is moving where is the energy coming from?
     
    Nearly all pacemakers are powered by chemical batteries which must be replaced every 5-10 years. Decades ago some were made with radioisotopes for power. New research is developing ones which utilize the bodies natural power sources to generate electricity. Nowhere in a pacemaker is a magnet.

    Until someone invents an entirely new material with the same unique properties, creating semi-conductor transistors requires rare metals.
     
    That's not how physics works. Current is induced in a conductor from a changing magnetic field. Energy cannot be drawn from a permanent magnet like a battery.

    Given that paper transistors seem to still be in the academic phase of things and not produced at any sort of relvant scale tells you that they are not near the point where the main problem is "increasing compute power". You'll have to build a working prototype of a CPU with paper transistors first and unless you're an EE or similar specialising in this area this isn't something random people on a forum can just "make happen".
    How will you make it happen?
    From a practical perspective, why would I want multiple computers for specific games? As you say there hypothetically would be very little cost, one can just print the 12900k and 3090 Ti once and be able to run every game at max settings and performance. There would be no need for different hardware configurations.
     
    Looking at e.g. this paper that looks into using paper these don't just roll out of your printer either. They're still tiny at micrometre scale and still use a metal-oxide-semiconductor, so they're not pure paper. At least the first iterations of such printers will likely be far outside of consumer reach as well, just like state of the art 3D printers.
     
    Does it work at "very, very low voltages"? Or is this speculation into it is imagined they'll work? Magnets don't magically give you free energy. A stationary magnet won't yield anything either, you'll have to make it move such that the changing magnetic field creates an electric field and hence current.

    greenhorn reacted to mariushm in woah, I've just learned what "heatsink fin skiving" is,, I wonder if that is common knowledge??   
    It's common knowledge for those that are curious or those in the profession. It's not a requirement to know. It's a cool process.
     
    For completeness, two other ways to make heatsinks are through extrusion or by forging 
     
    Forging is cool but requires heavy (as in tons) machinery and high pressures... basically you squeeze the aluminum into the shape you want

    In Romania, there's a classic, "sarmale in foi de viță de vie"   - viță de vie is grape vines, the bush or whatever is called, foi is leaves so basically Sarmale in grape leaves.
    If the're cooked right and the recipe is good, they're excellent ... and I'm leaning towards best served warm. 
    The leaves are not bad, a very tiny bit stringy, you'd feel those "branches" in the leaves but they break in pieces easily.
     
    Here's a recipe, the ingredients are easy to figure out.
     
     
    The "pickled cabbage" / sauerkraut variety is more common  , same for regular cabbage varieties ..
    Here's a recipe with pickled cabbage - this one has english subtitles so it's easier to follow :

    It’s time to build a new computer for work. My 4790K has been run for so long I wore-out a SATA SSD and cloned that drive. So this install was an upgrade from 8.1 to 10, then cloned and has been used for years.
     
    So, new parts for my upgrade:
    Asrock Z590 Phantom Gaming 4 i5 11600K Silicon Power A80 512gb NVMe EVGA BQ 850 semi-modular PSU Cougar MX330-Air case DeepCool 400 V2 cooler Parts I already had:
    Corsair LPX 2x8gb 3200MT  GTX 1060 6gb I built the system already, posted it, and have OS and driver install left, plus all my work-specific software. My plan is to buy more Ram, 2x16gb at least, maybe 2x32gb because I can and it’s conceivable I could approach 32gb and possibly exceeded it in rare circumstances with my workload.

    That method is interesting, but it can be abused (as can all tracking methods). From what I have read, I think it could be also be circumvented by randomizing some GPU parameters like clock and voltage in a small range, so that it is not noticeable for the user but still manages to throw off that tracking algorithm.

    I have had stuffed grape leaves several times with different stuffings and both hot and cold. I think I prefer them cold because the flavours turn out differently.

    When it comes to fig leaves, I am more skeptical (didn't try it yet). Those leaves should be quite difficult to chew and also when you break off a fig leaf, there is a milky, sticky liquid with a distinct odour coming out of the stem. I'm not sure how that tastes. Maybe they are ok if you cook them long enough.

    Summary
    A team of researchers from French, Israeli, and Australian universities has explored the possibility of using people's GPUs to create unique fingerprints and use them for persistent web tracking.
    The results of their large-scale experiment involving 2,550 devices with 1,605 distinct CPU configurations show that their technique, named 'DrawnApart,' can boost the median tracking duration to 67% compared to current state-of-the-art methods.

    My thoughts
    Oh bother. Another method of tracking us, and even more so with our precious GPUs. You know this is an awfully convienient time for just such a method of tracking, especially since we can't burn our GPUs. /s Jokes aside, this is honestly a bit frightening. Apparently, we can be tracked with the minor (seriously minor) performance differences of our GPU. This seems to be able to use any GPU that uses the WebGL API, thus meaning that literally everyone can be tracked using this (since practically every GPU (i or d) every web browser uses (or at least supports) the WebGL API (Correct me if I'm wrong). Thankfully this does also provide a way to counteract this. Namely scriptblockers and I should think that temperature and voltage changes should affect this as well (again, correct me if I'm wrong). Full research paper is linked below incase you want to read that. Well, hopefully Khronos gets a fix or patch out (if it's even possible).
