Greatest IT Screwups You've Ever Done

[Thanatos Telos]

Getting comcast for my ISP.

Kidding. Installing my 212 EVO the wrong way. Airflow was broken for a while.

I activated talkback mode on my smartphone once.
Your phone then starts screaming at you with every touch you make and the regular touch controls don't apply anymore.
Took me hours to figure out how to turn it off.
I suggest everyone try this.

Also ran a matlab script once which took two weeks to complete, only to find out I made a mistake in my script which left me with matrices filled zeros instead of useful data and set my research back two weeks.
