So we've been working with a VM at a university course I'm taking during semester break. Keyboard layout was QWERTY instead of QWERTZ, and I'm not used to the first layout, but no problem, I can fix that.
Or so I thought.

So I spend nearly half an hour trying to configure the VM to use the desired layout without altering the Ubuntu instance that much - only to then suddenly discover a small USA flag in the corner of the panel bar which could be changed by clicking once to the German flag.
This also changed the keyboard layout instantly.
So, yay, I guess. D:

I just got a phone call from "Microsoft" because there are Trojans on my pc. The broken English (and the content of the call) told me that it was scam, but I wanted to have my fun, so I continued the call.

After I told them that I am on my Computer, I was forwarded to an "expert", and now the funny part starts 😁

Scammer: you have your keyboard in front of you??
Me: yes
S: you see the strg, control ctrl button on the bottom left
M: yes *rly?*
S: what button. Is next to it?
M: fn
S: ...
M: ... *XD*
S: and next to it?
M: that's the windows button
S: ok, press that button along with 'r'
M: ok
S: what do you see?
M: *telling him what I see on my GERMAN pc*
S: ok, type 'eventvwr' *spelling it like hell*
I did so. Just while this spelling I could have hit my head on the desk... It was hilarious

He navigates me to the error and warnings and tells me that those are Trojans 😂 and that this is the reason some programs (especially my antivirus software) aren't running properly.

Well I told him that those aren't Trojans and that all my programs are running properly. I don't know if that was the reason, he stopped the call, but I wasn't able to connect to their 'headserver'.

In the end I am sad that I wasn't able to f*ck him up more. Maybe I would have been able to get some more information about their company to kick their *****.

Next time I will be (more) prepared

Last week I wired up my home network (including custom modem and routers) myself, because the stuff my ISP wanted me to use was garbage.
Luckily Germany has "router-freedom" so ISPs are not allowed to force us to use their device to dial into the network.
I did everything myself, because the 'technicians' they kept sending me were just idiots who didn't know anything, considering the highly paid job they are doing. Usually they told me, to get the device from my ISP, because my "Router" (actually a business grade, standalone Modem by Cisco, to feed my Router) didn't even have WiFi ( lol ). Also all Technicians didn't arrive at the agreed date but at some other time. I wasn't able to wait any longer.
So I did it myself.

Consider me something more like a student of theoretical computer science. Not actually supposed to be experienced with hardware stuff.

The ISP is serving me with a DOCSIS 3.0 Network based on the television cable network in my city. For some reason they are providing the internet-access to only one socket in the apartment, which has a rather uncommon "WICLIC" connector. After having trouble getting an adapter for WICLIC to common coaxial F-Connectors (used by every DOCSIS-Modem), I made one myself.

After setting up everything (not that hard, once the connectors fit) my modem told me, that, while I'm perfectly connected to the ISPs internal Network, I still can't access the internet.

So I called the ISP...
After getting ranted at, about that what I'm doing is illegal and only certified employees are allowed to do this and I will break more, than actually do good and that I can't just connect my own "Router" (again I needed to correct her: Modem) I hang up the phone.
Also she accused me of hacking their devices because I'm not supposed to see my IP address... (My Modem told me on its web interface. I didn't even need telnet for that.)
I went to the ISPs head office, told the first desk as many technical terms as I could remember and got forwarded to something like the main technician.

He was a really nice guy. The only sane and qualified person I dealt with at this company. He asked me for my Address and Device Model, I told him my MAC and last internal IP, I had seen and he activated my internet access within a minute.
We talked a while about the stupid connector that ISP is using in the homes and he gifted me some nicer adapters to connect my modem to the wall.

Why do ISPs hate their customers that much?

When the new head of the Computer Science program at our university comes to our help desk and needs help getting a Kali Linux box to connect to wifi... we have lost all hope (back story this guy is only head because he was the only one to take the job. he is a total tard... it's scary)
