GarlicDeliverySystem - Linus Tech Tips (original) (raw)

  1. Look at the Keychron V6 or V6 MAX. Not sure for how much they go in CAD, but should be around that price point.
  2. Then contact Keychron support and tell them. Having said that, bending the hotswap socket leafs back requires only some fine tweezers and partial disassembly of the keyboard with the provided screwdriver/ allen key; no soldering or stuff like that.
  3. No, this is not common and either a defect with the PCB (if all switches are equally affected) or some switches have bent pins/loose hotswap sockets. I'd reach out to Keychron support first before doing any DIY repair attempts, maybe you'll get a replacement PCB. Otherwise, you can inspect the affected sockets from the back of the PCB and check whether the solder joints are cracked, or slightly bent the metal contact leafs of the sockets together so they fit tighter.
  4. It would help to narrow it down, if we knew what you are looking for in more detail. What switches were in the K480, what do you like about the sound. What is your budget, how much work/effort do you want to put in yourself, etc. Layout requirements, i.e. 100% with US ANSI, or some ISO layout. Smaller, like TKL?
  5. Bold of you to assume I got property . Maybe I am waiting for the crash to gobble up city blocks worth of real estate. anyway, I lived in the US for a while and moved back to the EU. Some personal reasons, like being closer both physically and also time-wise (timezones can cause more issues than you'd think) was a huge boost to my well-being. But also the difference in how the economy works and stuff like health insurance etc. Now, I get that especially the latter won't be getting any better here with time and the demographic issues at hand. I also understand that highly-skilled people can make much more money and potentially have a 'better' life over in the US. Which might be relevant, given OP is a welder and would thus likely qualify for a nice job. My issue is just that most of your well-being is inherently tied to your job and economic success over in the US, much more than in many EU countries. Lose your job and don't find a new one quickly? Don't get sick and get ready to lower your standard of living significantly. Add to that the fact that OP might not want to move even further away from home and I wouldn't say it will be a huge improvement for their mental health to move even further to a different continent. On the other hand, a decade or so over there while saving up as much as possible, and they might be able to live a relaxing life back home after that. Not saying retiring, but if you can already pay off the house and have a lot saved up for retirement (not sure how the housing market looks in Bosnia, though), you are much more free in choosing a job. And maybe going away from an entirely consumer-driven economy that requires constant growth is not such a bad idea, at least for a while.
  6. Pretty sure many other european states don't look much different, Japan and SK also quite similar. So yes, there will be challenges ahead in a decade or so, but I would not call it a collapse.
  7. Given that this case looks like a custom job though, I would assume replacing it is not an option. Otherwise I'd consider taking only parts across the ocean and buying new parts at the destination. Usually cases, PSU and cooler are not worth taking on a plane in extra luggage, for example. Cheaper to replace these parts, unfortunately. If it was shipped assembled, then best guess is to contact the manufacturer for their recommended way of shipping. Maybe they even have a contact at DHL/Fedex/UPS etc. for you.
  8. If that was the case all the auto plants around me would be fully automated. Thats not the case. And the auto industry has had automation forever at this point. Some jobs need a human to do. Sure simple physical jobs can be automated. Jobs like in a fast food place can be automated. Customer service can be automated but people fucking hate it. The other side of it, is the costs of automation. It's not like you can just snap your fingers and automate. There are costs associated with automation. So a lot of places would have to weight out paying for automation vs just paying a person to do the job. Sure the costs will come down, but that will take time. I think the costs-vs-benefits part of automation often gets overlooked in these discussions. As you said, something that can be automated isn't necessarily so, simply because hiring humans to do it is so cheap compared to making custom machines. The example I always see is automotive welders and painting: both require the highest quality for the company, so employees would need to be trained well (costs) and paid well (to retain them) to do the job. On the other hand, the process is highly repetitive by design. Hence why chassis etc. are now mostly machine welded and painting in a lot of cases is down by robots as well. Things where the motions are not always the same or require subtle adjustments every time (e.g. cabling, interior assembly) are better done by humans, as the training costs are lower and you can easily transfer humans between different cars, models, kitting etc. For automated assembly you'd either have to design the whole car around it as far as I understand, or create hugely expensive machines that can adapt like humans can. The latter might be where AI could become relevant, as soon as a company figures out an AI model (and ASIC hardware, vision etc) to have robotic arms not run in terms of predefined XYZ coordinates and rotation, but in terms of "move part X into slot Y".
  9. Yes, but the 4.5L are just for the power of the CPU. You will have losses along the way, every bit of the machine that is connected to the outside will have small but meaningful losses over time. Put a GPU with 600W on top of that and you have quite a lot of liters per hour during continuous runs like rendering or simulation workload. It could be done somehow, but the economics is really not there, not even for a video. Easier to go with two or three 240L dewars and call it a day. Other issue that needs to be solved (not sure how they did it in the examples above, I haven't watched the full videos) is how you ensure adequate heat transfer and circulation of the LN2/N2. The expansion from LN2 to N2 yields several hundred liters of gas per liter of LN2, that need to be trapped, stored and compressed for the liquefaction machine (unless it just used a cold head and condensation). Alternative is to go with two loops at different pressures, a higher pressure 'hot' side where the boiling point is elevated, and a lower pressure cold side where the evaporation takes place and cools the high pressure hot side. However, you would still need to ensure that the liquid in the blocks and hot lines never starts boiling, or you would end up with a lot of pressure and issues for the pump.
  10. That thing in its largest version produces 120L of LN2 per day. Heat of evaporation for LN2 is about 160kJ/L, which is ca. 44Wh. A CPU that runs at 200 would run 12 minutes on that (approximately) , so you would need 4.5L per hour just for a 200W CPU under load. 120 / 4.5 = 26 hours, so that would barely meet the requirements. Issue is you won't have just 200W to cool, you will also have a lot of losses at cooldown and then some more in between. You likely won't run this at 200W under load (after all, what is the point of LN2 cooling if you don't put a RTX5090 under LN2 as well), but you also won't run the thing full tilt 24/7. So an average of 200W seems fair for a 6-8 hours of use a day. The thing you linked pulls 15kW, which is turned into heat and noise. You will need to get rid of that. You will need either lots of bottled, relatively clean N2 or another N2 gas generator. For what?
  11. closed loop or semi-closed loop systems have been shown at exhibitions in the past, look for videos on their channel or on DerBauer's channel, GN and Jay also highlighted them I think. The fundamental issue is that LN2 is not that easy to work with in a 'sustainable' way, for a few reasons: it is really, really cold. Meaning machinery to produce it is complex, as you have to go through multiple stages to cool air down due to no single refrigerant being able to just cool it. It also means a lot of heat is produced and electrical energy is required. This also means that overall cooling power (i.e. how many liters of LN2 you can produce per hour) is quite limited, unless you go to industrial scale again. Working with LN2 can be quite dangerous, as the boiling point of liquid oxygen is higher than that of LN2. Meaning if you are not careful, you can create puddles of liquid oxygen in your system. That is not good. You create a lot of gas when LN2 is used for cooling, since it is immediately boiled off. So you would need to have a recuperation and compressor system that can handle that amount of gas production. Again, some dangers and complexity involved here.
  12. For 50-60EUR you are probably better off looking at a membrane keyboard with those requirements. cheap mechanical keyboards nowadays are almost always TKL or smaller, with 65% and 75% being the most trendy ones nowadays. For about 100-150 you can get pretty decent full-size ones, but even then most "full-size" are actually 96% or other 'squished' designs or variations on 1800 style keyboards. The Redragon you linked has a few issues I see, not sure if they will matter to you though: low profile switches, meaning you also need low-profile keycaps should you ever want to change or replace them they also appear to be soldered switches, so apart from the limited compatibility, you also have difficult repairability.
  13. I would then just shop for a panel in that size and just be content with whatever wattage you can get.
  14. Well, I haven't looked up particular panels yet, however I thought it might be a quick exercise to see whether a 100W panel with 14" sides is realistic. Given that the theoretical max. from solar is around 1350W/m^2 at the top of the atmosphere and at the equator, this will be challenging. 14"x14" is 196 square inches, or 0.126 m^2, meaning the theoretical max. you could get before any losses to the atmosphere is 170W, so realistically you will only have a fraction of that over the day and at any latitude other than the equator. Put on top of that the panel efficiency of maybe 30%, and you have maybe 30-40W for a 14" panel at best. I found a folded 35x23x6cm one one amazon claiming 60W, but unfolded it is 86cmx72cm.
  15. I am not an IT person by any means, but your first concern raises some thoughts: what if the person thought they moved their files, but actually didn't? Like they had them in some network location, someone else's documents folder etc. and just the link got severed? I don't know how your organization has this set up, but we use Onedrive for all of this and sometimes during setup of new laptops we have both a local 'Documents' and a OneDrive 'Documents', plus now also various 'Documents' from different Planners and Sharepoints. So maybe they simply misunderstood what is going on there and you work off a wrong premise/data? Otherwise it sounds like a really mysterious windows error with no traces of the files to be found.
