I have my reasons that Socrates once tried to understand how Docker works, because I have exactly the same feelings.

Attended a Hackathon for the last two days as a Volunteer. Now I'm Home and feeling like Jon Snow.

A computer is Jon Snow . "It knows Nothing". Still does everything.

me: *goes to stack overflow to get some points*
*searches for questions I only know*
*scrolls down to find unanswered questions*
*keeps scrolling*
*finds a question I can answer*
*types in my answer*
*finds out that someone has answered
the question with better explanation*
*decides not to submit my answer*
*looks for other questions to answer*
*keeps scrolling*
*scrolls some more*
*scrolls for the last time*
*realizes I'm Jon Snow*
*exits stack overflow*

Built a C#/.NET application with support for a serial device. Tested it on systems A, B, C initially, all Windows system, same .NET version, same targeting, same build tool version, same initial connection configuration etc, etc.

Testing - works on A and C, B nopes.
...
OK, let's check the source, is there something about B that makes it impossible to execute that bit? - No, there is not, you checked that already, stop poking around, it definitively should work on B.
...
OK, maybe admin privileges, there is I/O involved, didn't need that on A and C, but who knows - nope, doesn't work on B.
...
OK, maybe something wrong with the connection settings? First try at reinstalling driver - but no, it doesn't work on B.
...
OK let's try with another device - more/less devices on B. Other USB ports. No. Still does not work on B.
...
OK, this is stupid, but, is the cabling alright? It is, of course it is, stupid - but it still does not work on B.
...
OK, at that point I'm just gonna ask a colleague, GrumpySoftwareDev whether he has any clue why it doesn't work on B. GrumpySoftwareDev knows nothing, but discovers that one of his applications doesn't work on Windows 10. You know nothing, Jon Snow, but it doesn't work on B.
...
OK, now I'm just going to ask another colleague TheLastOfHisKind who handed B down to me somewhat bluntly if he ever experienced problems when working with B and its serial configuration. TheLastOfHisKind tells me he does not and kindly offers me some input on the situation. Still no progress to get it working on B but he hinted he might have fucked up B's driver. I already reinstalled the driver but didn't reboot, which comes after reinstall.
...
OK, I'm just gonna remove and re-install the driver, then restart. Hu! Now the UI is gone but another serial device reacted on a general call. Not fully working on B but we're getting there.
...
OK, I don't know, I'm getting frustrated, let's borrow another system D - which has roughly the same configuration as B - from my colleague StrongCurrentGuy. StrongCurrentGuy borrows me his system and cautions me not to break it. I install the driver, plug the device and copy the application from B. It just works on D. Not on B though.
...
OK, you know what. I'm done. For shits and giggles I'm gonna remove that driver again, reinstall it and restart, maybe it'll magically work afterwar- WHAT THE HELL, I JUST OPENED IT AFTER RESTARTING, IT JUST WORKS - ON B!

... seriously, what the fuck. But yeah, at least it works now.

Am I the only one who hates dealing with IT support guys... they think you are like Jon snow and now nothing of IT

I've worked with few incompetent people till now, but one guy who stands out is my peer who is a "Lead Developer".

First of all he knows nothing!! Even Jon Snow knows something, but this guy knows absolutely nothing. And on top of that he has a hard ass attitude. Never sticks to coding standards, pushes unwanted configuration files to Git, uses too many nested loops even when not even a single one is required.

And when I suggest him something, he starts giving these lame ass reasons and tries to avoid my comments. Then I say, "good luck with that buddy" and move on!!

Client A: “What does that little button do? It looks so not fit in though. Can we just remove it?”

Me: “It basically serves as a sort function and to make those data look more tidy when you first input them. Especially when it comes from many sources, it .....blah blah blah.... So it's quite inportant to stay there according to UX basic.”

Client A: “??????????”

Me whispering: “Jon Snow.....”

Client A: “Sorry, what?”

Me : “Noooothing~ let’s talk about the other module shall we?”

After working at one internship: I have covered the basics of Development.
After trying to publish my own app: I know nothing. I'm Jon Snow of programming.

No experience in web, yet the radio guys in my university are pretty insistent on me building their website from scratch, "because I'm studying computer engineering."
I know nothin Jon Snow!
