Many short meetings.

Trying out cool gadgets like the segway. Looking out of the window all the time for the pizza hopefully arriving the next 10 minutes.

Peeking in interesting but foreign questions at StackOverflow after reading the answers related to the own project.

Googling after the possible causes and possible treatments when experiencing medical problems (without knowing if it's harmless or severe - for yourself or for a family member).

Using the company's desktop computers to solve cryptographic puzzles (like mining) on the company's computers while the boss and someone from the IT were asking to have a look on the machine after one guy already snatched my keyboard.

Very scary moment indeed but surprisingly it turned out: the real reason why they came was because a techadmin recently removed a shared system account but some faulty clients kept flooding the servers with outdated login credentials which also triggered mass SMS on the mobile devices.

Luckily I could somehow take an opportunity to remotely call the script which pulled the emergency brake which I prepared to shut down everything. Close call.

Nowadays I think it itsn't worth to take the risk just to do something that could also be done with the own home computer even it takes five times longer.
