Happens to everyone
Just having a multitude of terminals open with a mix of test environment and (just for comparison) an open connection to the production servers…
We were at a fair/exhibition once and on the first day people working on an actual customer project asked us, if they could compare with our code.
Obviously they flashed the wrong PLC and we were stuck dead at the first hours of the exhibition.
I still think that this place was cursed, as we also had to do multiple re-soldering of some connections of our robot and the sherry on top was the system flash dying - where I had fucked up, because I just finished everything late at night and didn’t made a complete backup of everything.
But it seems, if luck runs out, you lose on all fronts.
At least I was able to restore everything in 20mins. Which must be some kind of record.
But I was shaking so much from the stress, that I couldn’t efficiently type anymore and was lucky to have a colleague to just calmly enter what I told him to and with that we’re able to get the show case up and running again.
Well, at least the beer afterwards tasted like the liquid of the gods
Not OP, but can only speak from my experience: Installing a second WM/DE usually messes up my install, as quite some stuff is just from one GUI framework, so I don’t have to have to much stuff installed.
Also getting rid of it afterwards always wasn’t as easily possible.
I completely get trying out a WM y firing up a VM. You could even just boot the live USB stick to check it out.
But changing my working install just to try something (and then have to clean it up again) wasn’t working out for me in the past
