Just got my first IT job (I'm 19 y/o)
I am a C# programming teacher now :D for teens aged 15-18
I like it but I've had the chance to give the first lecture and there's this kid
Who is constantly interrupting
"Excuse me, programming is boring, when will you tell us how to break passwords"
"Excuse me, I have this neighbour I don't like, how do I put his printer on fire using code?"
"Excuse me, so we now know what classes are but can you tell us how to run fork bomb on system startup?"

I suppose the kid will be becoming famous here over time

Also, out of rant, what do you wish your lecturers said to you when you were just getting started?

Welcome fucktards! Yall are shit and im already sick of you.

As student I wished my lecturers denied those people in a class for a few lessons and then made an exam about those lessons. That way those annoying fuckballs know they should behave.

Really as a passionate dev I hated my IT school mainly because those people.

Really, you should kick that kid out.

I envy you a bit...
I love C# and I love sharing my knowlege. But if i meet a guy like that i would punish him severly.

Try explaning that coding isnt that easy. That hacking and exploitation takes years of skill and research.
And a bunch of buzzwords dont make you a programer.

(I would fucking love that job)

it's not in school btw, its private teaching I have a group of 12 kids

I wouldn't kick this kid out. Yes, he may be annoying as fuck, but I think this kid would have great potential if he is put in the right direction.
I would give him some special tasks for homework, not hard ones, but see how he solves it.
His interest in programming is there, he just needs a good guide. If he gets punished for this interest, it would just lead to a bad path, maybe even to become a blackhat if he's intelligent enough...
Being a teacher is not an easy job.

Teach them how to play poker and demand they bring real money.

Give the kid a warning and then kick it out. He may become a good dev later, but right now, he has to learn a completely different lesson in his life - not being an annoying dick.

I wish they would encourage all kinds of questions even if it seems trivial. We had this one guy who didn't explain shit and was like "oh thats trivial. You should remember this from school". No I dont. Either my school didn't have it or I don't remember but please encourage me for asking qustions where i seem to lack knowledge instead of putting me down. You are literally getting paid to explain that stuff to us. Goddamit.
Sorry.

“Hold your horses, Zero Cool, this is not a movie.”

For me, I don't really need to think of anything that my lecturer should have told me, I had a great programming lecturer the second time around.

I say that only because the programming 1 lecturer taught us only the basics and seemed to know just that, when it came to things like lab classes, I would ask her about things, before she would answer she would say "hang on let me get my notes...."

Second Semester she is gone! We get an amazing lecturer who could probably off the top of his head explain the basics - intermediate knowledge for programming, though it wasn't his knowledge just really how every was explained.

Also he made me want to get into game development more, so theres that lol.

To tell me how to forkbomb a system with HTML and a SNES

Damn if I had a skid like that in my class I'd just kick him out

Ask him to setup arch linux on his pc, or take a owasp course by selling his iPhone (if he has one).

Lucky! You get yo for a new generation of programmers! I wish you the best!

As for your question... I guess having known from the beginning what KISS and DRY meant would have been great. I mean, every teacher explains how to code, but I've never seen one explaining the best practices... Those are hard to learn later on imho.

...And wait, that annoying kid is paying a private course just to be annoying? Wow. Please, teach him deltree /y :<

Also dont start with frameworks before they know the basics.

And if you give assignments let them choose something they want to make with the techniques they need to learn. Nothing is as annoying as making something you dont like.

I've been teaching java in a private training center for two years now and very often I get people like that you need to make him sit down for a one on one conversation and map out a career goal in his field of interest and explain the importance of what you are teaching in that code
