I once met a person that never drank water, only soft drinks. It’s not the unhealthiness of this that disturbed me, but the fact they did it without the requisite paperwork.

Unlike those disorganised people I have a formal waiver. I primarily drink steam and crushed glaciers.

  • A method I have not seen mentioned yet (for when you have an old precompiled version of an app):

    1. Identify the missing libs. You can run the program, but sometimes it’s easier to use ldd
    2. Use your web browser to download the missing libs from Debian’s repos (stable or older if need be). Unfortunately you often also have to grab their deps too.
    3. Extract the .debs
    4. Move all of the .so files into the same folder as the old program you are trying to run
    5. export LD_LIBRARY_PATH=“$(pwd)”
    6. Now try running the app

    It often takes a bit of fiddling, but it’s worked for me a few times and you only need to fetch the few libraries you are missing. For bigger things however it can be a dependency hell, you might as well use the distro’s actual package manager inside a chroot.

    Note: You don’t need to be using Debian as your host distro, I don’t. As long as it’s a glibc based distro you should be mostly fine (glibc is mostly backwards compatible)



  • My distro recently dropped support for gtk+2 (which I am fairly pissed about, since it’s the last good version of GTK+)

    Stuff like this completely throws the shared libraries idea in the bin. There are lots of benefits, sure, but none of them matter when your program won’t even start.

    Please name and shame your distro. GTK2 is a core component of userspace for many users, just as important as glibc and bash. Maintaining it might be annoying, but it’s the lesser of two evils.

    My distro (Void Linux) dropped support for qt4 a few years back. Now I’m running QUCS in wine. “win32 is the only stable ABI in Linux”

    (And yes you’re right 2 is the last good version of GTK+. Gtk3 and 4 look and feel so much worse, they make me feel like I’m being punished.)


  • Lawful good: Please don’t use 8P8C for anything other than 10/100/1000BASE* compatible protocols, especially on network devices. It’s confusing.
    Chaotic good: Please don’t use ethernet cable for anything other than ethernet compatible protocols, especially on ethernet devices.
    Lawful evil: That’s a valid use of Cat5 cable.
    Chaotic evil: Let’s talk about RS-485

    True neutral: Wires are just wires and standards are just standards. In a parallel dimensions, somewhere, cat5 is used for 8-phase delta mains power.

    Sorry for the late reply, tied up. Thankyou for the photos.

    The Z-axis leadscrews look OK in the photos (nothing obviously wrong). That’s a very clean and new printer.

    Q1. Is there any grease on those Z-axis leadscrews (tall metal spiral rods) or are they completely dry?

    Q2. If you force your printer to move up and down does it make unusual noises at some parts of its travel height? You can try typing thing g-code into your printer monitor software to make it move up and down:

    G0 Z100 F1000   (move to Z position 100mm.  You won't actually travel at 1000mm/minute, instead the printer will do whatever it's max is)
    G0 Z0 F1000    (move to Z position 0mm, ie nozzle touching the bed)
    

    You may need to home the axes first (G28)

    Q3. Are these screws on both sides properly tight? I think I might possibly see a gap under one, but it could also be an optical illusion from reflections.



  • SFF = Small Form Factor. It’s smaller than traditional ATX computers but can still take the same RAM, processors and disks. Motherboards and power supplies tend to be nonstandard however. Idle power consumptions are usually very good.

    USFF = Ultra Small Form Factor. Typically a laptop chipset + CPU in a small box with an external power supply. Somewhat comparable with SBCs like Raspberry Pis. Very good idle power consumption, but less powerful than SFF (and/or louder due to smaller cooler) and often don’t have space for standard disks.

    SBC = Single Board Computer.
