Linux

delete everything in /tmp; you're not really using it anyways and you'll get more disk space. lol

i literally used this same logic when i merged the contents of c:\windows & c:\win32 because there were so many duplicate files and folders and i needed to recover the free space.

sometimes i'm thankful for my cluelessness; examples like this paint me into corners and this particular corner was the impetus behind my exploration into linux; which has sustained my career for the last 25ish years through several once-in-a-lifetime economic recessions and multiple personal setbacks.

linux is the best mistake i've ever made.

once you have some experience under your belt, these are non-issues:

• deciding to “learn Linux” the hard way by starting with a specialized distro (Slackware, Gentoo, Alpine)
• switching to unstable or testing branches before you’re ready ’cause you want bleeding edge or “stable is too far behind”
• playing around with third-party repositories before understanding them (PPAs in Ubuntu, AUR in Arch)
• bypassing the package manager (especially installing with curl | sudo sh)
• changing apps for no other reason than “it hasn’t been updated for a year”

Overclocking

Instability you ask? This is like a slow creep to instability and freeze your system. It's called the Bash Fork Bomb (look it up if you want), but it's a copy/paste you put in and it slows your system down by consuming all the system resources and cause it to lock up HARD. It goes away after a system reboot, though.

I was going to post the code here, but decided to play nice. But if you are curious:

(edit: Made 'slow' 'slows')

Go through all installed packages and remove "bloat".
Add third party repositories.

Mess with grub, without really understanding what you're doing.

Also, "meep".

Trying to mount an iso image in the terminal and accidentally un-mounting your root drive.

Totally didn't do that before...nope not even once, definitely not twice >.>

Installing GPU drivers :). Bonus if you need to use CUDA on top of that

Apparently running an update on Fedora. My flatpaks were broken on Fedora 40, so I thought it's a configuration issue on my part and did a clean reinstall when Fedora 41 came out. Issues were not present... until I ran an update.

Just my experience, I was unable to log in after trying to add samba to my installation. Had to boot into live usb and reset my password.

Maube I'm just bad and it's not samba.

sudo rm -rf /boot /efi
