Was at school the other day and met a dude who was told by an acquaintance that I'm a "computer guy".

Dude comes up to me and jokes that the acquaintance was spreading rumors about me being a programmer. I was a bit confused and tell him that I do in fact program, and then he asks me what I've done, to which I explain what languages I've dealt with.

Next thing he asks me: "Have you made an OS?"

BREH

He tells me about how he went through Linux From Scratch. I have no idea how in-depth that book goes, if someone who has read it could enlighten me that'd be nice.

Acquaintance mentions that I won an app contest. (At this point, I'm internally telling acquaintance to shut his face.) I explain what I made(an Android app that helps sort Lego pieces) and he promptly tells me that I just used an API and barely wrote any code.

After (hopefully calmly) going back and forth with him, I just say "So I write bad code. What's it matter to you?" He stopped talking right there.

He apologized later. Yeah right, I'm sure you're sorry.
