From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What is the most duct-tape thing you've done to Linux? (lemm.ee)

tell me the most ass over backward shit you do to keep your system chugging?
here's mine:
sway struggles with my dual monitors, when my screen powers off and back on it causes sway to crash.
system service 'switch-to-tty1.service'

[Unit]
Description=Switch to tty1 on resume
After=suspend.target

[Service]
Type=simple
ExecStart=/usr/local/bin/switch-to-tty1.sh

[Install]
WantedBy=suspend.target

'switch-to-tty1.service' executes '/usr/local/bin/switch-to-tty1.sh' and send user to tty1

#!/bin/bash
# Switch to tty1
chvt 1

.bashrc login from tty1 then kicks user to tty2 and logs out tty1.

if [[ "$(tty)" == "/dev/tty1" ]]; then
    chvt 2
    logout
fi

also tty2 is blocked from keyboard inputs (Alt+Ctrl+F2) so its a somewhat secure lock-screen which on sway lock-screen aren't great.

My mother uses some software that runs in the browser for her shop. It can print out receipts and scan items. To do these things it has a small "sattelite" application that runs on the system and interacts with the printer and scanner. This software only runs on Windows and Linux doesn't have drivers for the scanner.

When I switched her over to Linux and found this out in the process I wanted to stop, give up and install windows.

But then I had a stupid idea. I could run the sattelite program in a Windows VM and pass through the USB devices for receipt printer and scanner. The webapp uses requests to localhost:9998 to communicate with the sattelite so I set up a apache server that proxies these requests into the VM. I also prevented the VM from acessing the Interner so Windows doesn't update and screw everything up.

And it works. It has been in use for a week now and I've heard no complaints. I'm just praying to god it doesn't break

At least getting a snapshot of the Windows VM should be simple. And since it doesn’t connect to the internet and doesn’t update, restore should be quick and relatively easy.

Create a script to send important data records (if you need that for taxes or inventory data etc) as a nightly routine, that way you have a consistent database for any important records.

Then just create a restore point. If it breaks in 2 weeks, then you just relaunch it and know that it's going to kill itself in 2 weeks. A simple restart to that restore point solves everything.

Sounds 100% functional to me!

I wonder if the windows docker image could be of use?

[–] delirious_owl@discuss.online 3 points 3 months ago (1 children)

Is there such a thing as a windows docker image that doesn't run Linux on Windows?

[–] BlueEther@no.lastname.nz 2 points 3 months ago (1 children)

I saw a reference to it the other day but didn't look further, it looks like the windows docker image can only run as athe same os as the base release

[–] delirious_owl@discuss.online 2 points 3 months ago

Ah right, useless.
