    Eigenvektor reacted to Agall in Do I need to install these bracket things on my GPU?   
    I don't think its possible in a normal case to maintain enough positive pressure to keep a GPU fan from intaking from PCIe slots right next to it. With relatively ventilated ones its less likely, solid ones obviously wouldn't.

    Honestly I go heavy on positive pressure and leave these open so the GPU heat gets out the case quicker (In theory)

    no, the activation code is just checked against the microsoft servers.
     
    it cannot be used for remote access.

    Eigenvektor got a reaction from Yolky-List in How to Optimize a Home Lab VM Server for Gaming?   
    Before you go all out and spend money on anything, I would try gaming on your PC through Parsec from an external location first. If your ISP blocks it, or performance isn't convincing without a VM in the mix, you can probably save your money.
     
    Which hypervisor you use isn't going to matter too much. The primary concern is that it needs to support GPU passthrough and it needs to do so for at least two GPUs. A hypervisor that runs on bare metal (e.g. ESXi) might have a slight performance advantage, so would be my go to in this scenario. You can probably achieve the same with a Linux machine running KVM.
     
    A consumer level CPU will work as well as a server CPU, the primary concerns are cooling, enough cores and enough PCIe lanes for two GPUs. If you want a CPU capable of effectively powering two gaming machines at the same time, you'll want one with at least 16, or better yet 20 cores minimum (20 P-cores that is, in case you're thinking of Intel). You'll also need a motherboard with slots for two GPUs.
     
    You'll want to assign between 6 to 8 cores to each VM and leave the rest for the hypervisor. You'll also want at minimum 64 GB of RAM. Ideally you'd want to assign 32 GB to each VM, but have enough left over for the hypervisor itself, so probably more like 80 GB+.
     
    Even with that, there's no guarantee that the VMs aren't going to negatively impact one another if both are running a full gaming workload and competing for shared resources (such as memory, disk and/or network bandwidth)

    Eigenvektor got a reaction from rikitikitavi in iPad 4k?   
    For the sake of comparison, your typical 16:9 monitor with "4K UHD" uses 3840 × 2160 pixels. (4096 x 2160 is DCI 4K).
     
    At 32" that is a pixel density of 138 ppi, so a fair bit lower than the iPad.
     
    Of course your viewing distance is usually farther away, so it's likely the same clarity.

    Don't worry, you did it properly 😉
     
    Building your own really isn't that difficult. There's also a sub-forum where you can ask for recommendations on the components you picked: https://linustechtips.com/forum/18-new-builds-and-planning/
     
    Not in the UK, so not sure which place would be reliable for pre-built computers or buying computer parts.

    Eigenvektor got a reaction from Mark Kaine in Hyper backup , compression or not ? 1 hdd daily backup , 1 hdd backup one time or monthly   
    As I said, it really depends on what you're backing up. If it is mostly text files you can save a ton of space. If it is mostly images and video, compression isn't going to do much, since the files are already compressed.
     
    No compression is going to be faster, and easier to access without requiring specific software. So in that sense I agree with @Mark Kaine, it's usually the more sensible option. Compression primarily makes sense if you have a ton of (highly compressible) data and can't afford disks that are big enough.

    Eigenvektor got a reaction from Fat Cat11997 in Can better antennas help wtith ping on pc?   
    DNS has absolutely nothing to do with ping.
     
    If the DNS server you're using is slow, the initial lookup that resolves a host name to an IP might take more time. Which means initial connection to the game server might take longer than usual.
     
    But once the IP has been resolved and a connection has been made, DNS is no longer involved in the communication at all. So the ping you're seeing while in game is completely independent from DNS.
     
    If ping is higher than before, there are multiple possible explanations. Maybe the game server moved to a different location that is further away. Maybe the game server has more load than before. Maybe your ISP or any intermediate ISP changed their routing and there are now more hops between you and the server.

    DNS does not impact ping.
    DNS takes, for example, google.com and translates it to an IP address. That mapping is then cached locally on your machine for a period of time.

    That's "normal" and it is arcing inside. Don't do that, or try and do that. It's not normal for someone to try and hold a switch in between positions. It should be flipped on or off. You will mess up the contacts if you keep doing this.

    Eigenvektor got a reaction from Gat Pelsinger in Is this possible in Linux?   
    As I said above, there is likely some kernel level power event you can subscribe to.
     
    Otherwise, I would suggest a slightly more conservative approach. The battery percentage is unlikely to change significantly in 1 second.
     
    When the app starts, query battery percentage and projected battery life. Use that to estimate when the battery will next go down by 1%.
     
    Use that estimation to determine when you should query again.
     
    When you query, check the expected delta vs the actual delta, use that to adjust your poll rate accordingly.
     
    Do all of that in a low priority background thread. Only update the UI when percentage has actually changed.

    <-- as you can see by that badge, I did contribute to folding.
     
    During that time the down payment for my power bill doubled. And that was back when I still paid 32 cent per kWh. Since then the cost for electricity has gone up to 43.5 cent per kWh (+35%), as has the cost of everything else.
     
    If you have parents who can just shrug that off, cool. If you just shrug that off because it's not your money, uncool.

    Not really. As I said, it can work as a neat space heater. Not gonna beat a proper HVAC system for anything but a single room though. My power bill doubled when I ran a few GPUs 24/7 for a folding event. In winter, so assisting the HVAC not fighting it.
    Not everyone can do so, nor do they want to.
    🤓 <- that's the only appropriate reaction I have for this statement lmao.
    You assume everyone's parents can just magically afford a higher bill. Mom and Dad don't poof money out of a hat infinitely for their kids projects. I've had the privilege of financially stable parents who can both shrug off an increased power bill and have helped me financially in a bunch of other ways, most people do not get that. It is very important to understand that that is a less and less common privilege these days, so you don't come across as an entitled twat.
     
    I don't get the fixation on F@H. As I said earlier it seems to be going fine, and they regularly have more hardware than they can actually use enrolled. I'm not sure what point there would be in the masses running F@H on very slow and inefficient devices (really anything but a decent to great GPU is practically useless for F@H, I only run CPU folding when I want the heat output). If you want to effect the world in a positive way, look into how batteries are produced from raw materials to final product (both environmental and human cost), then come back and advocate for burning through the limited useful life of mobile and laptop batteries to accomplish barely anything as F@H doesn't scale well on those devices. If they could even be served work units.
     
    On the speed of F@H, back during the covid push in 2020, the network was 2x faster than the fastest supercomputer on the planet: https://www.tomshardware.com/news/folding-at-home-worlds-top-supercomputers-coronavirus-covid-19. This article also does a good job of mentioning that you can contribute with your hardware if you want, but not being too pushy over it.
     
    On mobile, unless they've changed it, DreamLab seems especially bad on modern phones: https://foldingforum.org/viewtopic.php?t=32951. Relevant bit here:
    Lots of even cheaper phones now are often OLED, seems a bad idea to try and kill screens faster for dubious benefit.
     
    TLDR: Folding @ Home seems a weird thing to want to get regular (non-techie) folks into. It's doing very well (again AFAIK, I haven't seen some massive "we're losing hardware help" message from the F@H team, and we have some hardcore Folders here on the forum so it would have been mentioned if so) in its niche, and doesn't really fit anywhere else due to a multitude of overlapping concerns that may or may not be an issue depending on the individual non-techie person.

    Try pinging the modem in your home. Most likely that ping time is below 1 ms (at least on cable). That's the only portion of ping you have control over.
     
    The rest of the ping time will be the distance between your modem and the server you're connected to.
