  • On this deserted island I could use some help()

    Jump

  • help now actually opens the help utility on Python 3.13!

  • Good experience with neko remote browser

    Jump

  • Perhaps there was an easier lighter-weight way of doing this?

    Yeah, SSH tunneling. What I would do (and have done in the past) is something like:

     
        
ssh -L 8080:192.168.0.1:80 myserver

    That will forward port 8080 on your host to port 80 on 192.168.0.1, so you can access your router's web UI with http://localhost:8080/ in your own web browser.

    You can also setup full tunneling with SSH, but that requires messing around with SOCKS and I usually can't be bothered.

  • I make all my videos using Linux. Here's how. | Veronica Explains

  • If we're suggesting a GUI for basic trimming and splicing, I prefer Avidemux, it supports cutting without transcoding the whole video (as long as you cut on an I-frame), saving time and reducing artefacts.

    UPS input load

    Jump

  • Ahh sorry, I thought you meant you plugged it into the input side. If that's the case then are you running anything that measures CPU usage? I run the TIG stack, it might be able to give you some hits. Also back to my original point which is already unlikely, if it's a modified sinewave UPS, it can confuse some measuring devices while it's on battery.

    UPS input load

    Jump

  • It's weird to do this daily, but it's possible that the UPS is doing a self test, which would drain the battery a little and the load is from charging it back up.

  • Mom can we have Scratch? We have scratch at home. Scratch at home:

  • The symbol they defined out is not the equals symbol but rather U+2550, so the for loop is fine.

  • Is "AI" A Buzzword?

    Jump

  • Before other people start commenting 'yeah obviously', it's their April Fools video, it's pretty funny.

  • Android Self hosting

    Jump

  • You have to be on the March update, then go to Developer options -> Linux environment, and enable it. Then 'Terminal' will appear in your apps drawer.

  • How I helped fix sleep-wake hangs on Linux with AMD GPUs

    Jump

  • I hadn't restarted my serial logger after I rebooted my laptop, leaving me with no clue about what caused the crash.

    Probably way too late now, but if it was a proper kernel panic, it should've saved the dmesg in the kernel's pstore which saves to either ACPI or EFI storage (depending on BIOS or UEFI), which systemd then extracts to /var/lib/systemd/pstore/ on next reboot.

  • Oh damn, phoronix comments are usually bad, but they really got off the rails this time!

  • ESET in Germany recommends installing Linux as alternative for older HW running Windows not supported by Windows 11

    Jump

  • Ahh okay, that description kinda sounds like floppy drive power, but it probably is a proprietary thing.

  • Could also be slimline sata.

  • Probably a long shot, but if you live in Australia (or maybe also New Zealand), Jaycar often sells the Ender 3 V3 SE for AU$250, which seemed like a really good price compared to other places I found.

  • Linux Kernel Patches To Use AMD INVLPGB Instruction Show Huge Speed-Up

    Jump

  • I couldn't find a hard answer to whether this supports EPYC only, or Ryzen too; so I put together this script to read the CPUID to detect for INVLPGB support according to the AMD64 Programmer’s Manual, and my 7800X3D does not support INVLPGB.

    (Let me know if I've made an error though!)

     c
        
#include <stdio.h>
#include <stdint.h>

int main() {
    uint32_t eax, ebx, ecx, edx;

    eax = 0x80000008;

    __asm__ __volatile__ (
        "cpuid"
        : "=a" (eax), "=b" (ebx), "=c" (ecx), "=d" (edx)
        : "a" (eax)
    );

    printf("EBX: 0x%x\n", ebx);

    if (ebx & (1 << 3)) {
        printf("CPU supports INVLPGB\n");
    } else {
        printf("CPU does not support INVLPGB\n");
    }

    return 0;
}

  • That's INVLPG which has been there since the 486. The AMD64 Programmer's Manual has some info on the differences between INVLPG, INVLPGA, and INVLPGB though.

  • Running Windows is officially supported by Apple, yes most guides use bootcamp to set it up, but you should be able to create an install drive like a normal PC and boot from it by holding Option/Alt as you press the power button. Mac's usually just use EFI like any modern PC under the hood.

  • Nah, bootcamp assistant is Apple's dual boot setup tool, it is a native install, but it has to be started from MacOS.

  • How does hypixel have their website and minecraft server on their root domain? (I would like to do something similar)

    Jump

  • TCP and UDP can listen on the same port, DNS is a great example of such. You’d generally need it to be part of the same process as ports are generally bound to the same process

    They don't even need to be the same process. I'm pretty sure that's just a common practice if something needs both protocols, but there's nothing stopping you from having a web server on TCP 443 and a VPN server on UDP 443. Ports are an abstraction brought by each protocol, they aren't in anyway related.
