    Ryzen: Strictly technical

    The Windows scheduler is already NUMA-aware and can tell the difference between logical and physical cores. It has everything needed to schedule work on Ryzen efficiently (except for perhaps some power control stuff), and just needs to be aware of the processor's core and cache topology.

    Official AMD Ryzen Benchmarks, Reviews, Prices, and Discussion

    This is wrong, and you've repeated this misinformation multiple times across multiple pages. Threads aren't free. If you have more threads scheduled to run than processors that can run them, the OS has to context switch, where it has to stop the thread, save the memory that it's using, evict...

    Ubuntu 14.04 Unity slowness

    I run Ubuntu on my 2007-era laptop which is much slower than the OP's PC, and while it's not blazing fast, I haven't encountered the problem the OP is experiencing.

    Ubuntu 14.04 Unity slowness

    Newer desktop environments like Unity, Gnome 3, Cinnamon, etc. require a compositing window manager, which in turn requires a working 3D accelerator. If your 3D accelerator is inadequate or not working properly, it will fall back on llvmpipe (a software 3D rasterizer), which is relatively slow...

    Why does yum/apt repos sometimes all fail with 404?

    The Ubuntu apt repos take up a substantial amount of disk space, and it's unreasonable to ask mirrors (who are all volunteering their resources) to maintain obsolete repositories indefinitely. Ubuntu offers LTS releases for precisely this reason.

    Good defragging program for Linux?

    Whether a defragmentation tool is available depends on the file system you're using; however, btrfs, ext4, and xfs (one of which you're likely using on a modern distro) all have online defragmenters available.

    Best version of linux

    If you're looking to develop apps for Linux, you should target Debian and Fedora, as these are the upstream distros for most of the major Linux distributions.

    How do I force permanently a file extension to always open with same program?

    Linux does not make any file determination based on file extension; rather, it inspects the physical format of the file and uses that to determine what type of file it is. You can manually inspect a file type by running `file <some file>` at a command prompt. KDE identifies files based on the...

    How do I force stop a md array?

    /proc/9583/exe This is a symlink to the command that started the process. Knowing what the command is should give you a better idea of what the process is doing and why it's stuck. You can also run `strace -p 9583` to find out exactly what that process is doing.

    How do I force stop a md array?

    Linux locks disk resources if something is using the disk. This can be problematic on NFS mounts where the remote host no longer exists, but if Linux is complaining that something is still using a local disk, it's probably correct. You can use the 'lsof' command to find the process that is...

    Which smart switch? HP V1910 vs. NetgearGS724T-300NAS? (Went with the HP V1910)

    Wow. You dug up quite an old thread just to ask that. I guess I should be flattered :P You can check if a switch is non-blocking by comparing the maximum theoretical switching capacity of the switch (based on port count/maximum speed) with the manufacturer's specifications. According to the...

    What actual speed should I be getting connected to a Gigabit ethernet port?

    If your application is testing network throughput, and you're getting 2-3Gb/s over Gigabit Ethernet and you're not using any type of link aggregation, your testing application is screwed up. If you want accurate results, test with iperf instead.

    NFS randomly hiccuped, now everything is screwed up

    resolv.conf can be overwritten by NetworkManager, as well as the configuration scripts that various distros use. Unless you're using a positively ancient distro, there should be no reason to modify resolv.conf by hand.

    Access NAS FTP using IPv6

    Port forwarding is a concept used by NAT, which is an IPv4-exclusive function. For IPv6, to access your NAS, simply use the NAS's IPv6 address. If your router has IPv6 firewall functionality, you will need to ensure that your NAS's IPv6 address is accessible to the outside world, and that it's...

    swift / Ubuntu hardware question

    The limitation of BIOS is very specific: you cannot boot from a boot disk that is greater than 2TB. Getting around this is easy: use a RAID controller, either external or the one built into your motherboard. In the RAID controller's configuration screen, create a new disk array (if you only...

    Random letters are bolded in emails

    I just encountered this problem on my work computer today, and only on a combination of certain letters. In my case, it seemed to be specific to the font 'Calibri' when rendered below a certain font size. Switching to a different font or forcing the font size larger resolved the problem. I...

    Everytime I try Linux, I don't last a day.

    Linux instructions are often given for the command line because they're convenient to copy and paste, and these types of instructions are generally compatible with most distributions. If you want a graphical configuration interface, your desktop environment will have one available. fstab is...

    Everytime I try Linux, I don't last a day.

    I get what you're saying, but the problem with your comparison is that Linux is not a monolithic one-size-fits-all platform. There are platforms that are designed to be very easy to use, even if it mean sacrificing functionality (Android, and SteamOS will likely fit in this category), there...

    Question about changing motherboards and (not) having to reinstall Windows

    On modern versions of Windows? Storage controller drivers. If you're using a generic IDE or SCSI driver, or your storage controller is moving with you (e.g., you're using a hardware RAID card), you don't need to re-install. If you're using a 3rd-party driver specific to your storage controller...

    Is it normal for KVM/Qemu to be this slow?

    Fedora Core 9 is very old, and KVM wasn't nearly as mature back then as it is now. I'm not sure what the purpose of using such an old OS is, but if you're married to it, you may want to use Xen or Virtualbox instead of KVM.

    Ubuntu 14.04 Sluggish Performance

    Nope, sorry. Ubuntu 14.04 is pretty snappy from what I've seen. If Linux just seems to be lagging a bit for no apparent reason, you may be running into a name resolution issue. Make sure that you have DNS set properly, and if your DNS server doesn't have an A and PTR record for your machine...

    Is it normal for KVM/Qemu to be this slow?

    KVM is the fastest hypervisor I've used to date, and it's rock solid. If KVM is truly as slow on your PC as your described in your OP, either you're doing something horribly wrong, or you have the world's shittiest hardware. I'm not sure what you're doing with your VMs, but 512MB may be low...

    Is it normal for KVM/Qemu to be this slow?

    You're probably not using KVM, so QEMU is falling back to software emulation, which is dog slow. I've also seen this if you grossly overcommit the VM's memory, but you'd see a lot of disk activity in that case.

    Windows Is a Turd

    Is it possible for WiFi to have an "unclean signal"?

    I don't know. It's kind of hard to know for sure without diagnosing the problem as it happens. However, if your problem was with your wireless connection, you would experience problems with all communication attempts, not just to this one particular site.
