Hey /g/, whats the worst mistake you made on a computer or any device? We aren't perfect obviously, but there are some really dumb things we did at some point.

I'll start:

>>Be me
>>Install bumblebee and primusrun on Ubuntu for steam
>>accidentally sudo apt remove bumblebee on both
>>fuck up the system so bad i had to get it restored
>>mfw 1 yr of programming work down the drain

extra points for hardware related issues or Ubuntu/Debian systems
My laptop key got popped out and instead of putting it back I threw it out.
I was a dumb kid.
I had my F11 key pop out on accident once, and I left it sitting next to my computer. My dog ended up getting to it and I found it later in his bowl, partially chewed up.

Even today, I dun fuck up.
Forgot to clean the dust out of the front air vents on my PC at a time when I was doing a lot of gaming. by time the computer started having issues, it was already too late. I lost a motherboard, a power supply, and a hard drive to overheating.
>Be me
>Installing Linux for the first time. Age 14, circa 2005.
>Didn't bother to read the parted manpage.
>Ended up deleting all existing partitions
>No backups
>Lost years of short stories
My cousin had a computer like what you mentioned. He was one of those hardcore gamers that had a monster system and needed the max amount of venting possible for it. After like 3 years of having it, not even cleaning the vents, the CPU got so hot we actually found melted plastic at the bottom of the case.

We figured it was some Lego he accidentally dropped in there because of his brother, but we still don't know to this day.
Installed Windows ME.
The fuck up was not backing up.
>accidentally sudo apt remove bumblebee on both
You'd still be able to get your files, not like it screwed your filesystem retard
Was a newfag to ubuntu back then, and I knew I could get to the files, but didn't have the knowledge then how to.
Im not sure but:

Bought an i5 4690 instead of 4690 to my B85m motherboard

1996, tech support instructed me to "deltree windows" on my win95 box before I knew anything about computers. Seeing a blinking DOS C: prompt was terrifying.
I've never had any big incidents with PCs.
The worst thing I've ever done was flip the red switch behind the PSU to switch it from 115V to 220V.
PC didn't turn back on for days.

and that was my first dance with linux
There was a time when I thought I could turn my PS3 into a Linux system using a thumbdrive when my computer broke down. It turns out I needed to do a whole bunch more to make it into a linux system than I anticipated.

I tried to make it work but ended up fucking up the insides of the PS3 with my attempt for a complete factory wipe all the way to the base model of it.
Your biggest mistake is that you could have easily retrieved your data, idiot.

Something felt so wrong when I went back to get it, it's true you feel your loved ones go...
tilted my computer to mess with wires behind it

it slipped, fell and wouldn't turn back on

checked connections

checked all the boards

nothing was wrong and i started to freak...

til i noticed the power supply switch turned itself off
How were you that fucking stupid?

I mean, even if you haven't been backing up it's simple.

login without GUI. Get your fucking files. THEN reinstall.

Was the HDD kill?

Pretty clever.
I remember I was building my current rig and I put watercooling in it. I ended up leaving it open while I was in the bathroom, which was fine until my brother took a pair of scissors to the tubing and cut them. It wasn't activated with the water and everything yet, but it was a pain to cut again.

I remember my friend and I as kids were online and we found this ad for dietary pills. Being curious, we pressed on one, only to be scammed.

Also, there were the pay-to-play in game currency "code generators" they had. Those always sucked.
tar -cvf *.cpp *.hpp Makefile

I made this mistake a couple of weeks ago. I now use Git for everything and commit any time I so much as think about archiving my sources.

Also, deleting a Linux partition while forgetting that that's where my master boot record was located.

That, friends, is why I no longer play ANY computer games. I am too weak.

I am just some filthy casual that plays a couple game of Black Ops 2 a day or something.
When I was 12 I tried installing Ubuntu from a CD-RW and the Live Disc feature wouldn't work so I figured yea I'll just install it. I got a grub-rescue prompt and panicked. My dad brought my PC to best buy and Geek Squad told me I had a broken Hard drive and CD drive. I knew all I needed was a format I just didn't know about Gparted and shit. 200 bucks later and an asswippin' I was scared of Linux. I was happy with my Vista.

Swapped my Chinkpad screen without taking out the battery. Now theres a nice pair of cables running below the keyboard that shouldnt be there.

Whats worse is there wasnt a real reason to swap it to begin with.
Didn't eat my pride and get a php dev position during the pre2k boom. I could have, and I just couldn't do it. Big mistake. Could have bankrolled my education, travel, retirement, instead of only taking jobs that used technologies I liked.

RIP my old Xbox Live account. I had just finished One Shot One Kill on veteran on CoD4 earlier that day as well.
At least you learned.
set up new linux workstation, spending hours installing shit and configuring

three weeks vacation, come back, forgot password

Almost had that happen to mine until I realized later it was a fraud. This was with Sony's PS3 though.
Why would you buy Xbox 360 in the first place?

This. You could simply get Wii and play your childish games. Or you could get the damn ps3 and play the japanese shit or other exclusives. And finally, PC master race.
Good riddance.
We all got scammed in some gaming-related event in our childhood at least once, mate, at least we have learned from it.

Both forward and backward slashes do not require a shift key on the US and ISO layouts.

Lost out on an easy gig selling them on ebay which I could have made another $800.

Felt so fucking stupid
Nothing too major. Maybe when I tried to clean my G700 with rubbing alcohol and ruined it but that was just a minor enough mistake that only cost me like $70 to replace (though the G700s uses noticeably shittier software which still pisses me off) I did accidentally wipe one of my main storage drives when reinstalling Windows as well and accidentally picked the wrong drive, might have been able to recover some but I just couldn't give a shit.

Wasn't really my mistake but I remember when I was a lot younger my dad built my PC for me and accidentally screwed a screw in the wrong place somehow (still not really sure how he did it) that shorted the motherboard so badly that it burned a huge hole into it and ruined it. Stank my room up with an awful smell for a while too.
