So as you may or may not know, I am a sophomore in high school. (Grade 10, or Year 11). I've known this kid since I was in 5th grade (year 6). He thinks he's the coolest kid on the planet. He claims to be a professional at everything. He thinks he's an expert at computers because he owns an extremely old Alienware desktop. He basically thinks that he's super smart, super attractive, super funny, super cool, super good at computers, and a super good hacker. He thinks he's a hacker because he's in a Java class. The Java class is an elective (optional class) for people my age at my school. Most of the people my age at my school are taking the same class. However, this "hacker" is getting an awful grade. But he thinks he's a hacker because his father works in software engineering, with C++, which he claims to be an expert at, himself. (Side note: He is garbage at that as well. I asked him for some proof of his knowledge of C++, so he wrote the "Hello World" program in Python, but used all caps. I don't know a single thing about C++, but I am like 90% sure that that's wrong.) Anyway, so our little "hacker" thinks he's super good at computers. He constantly rips on the fact that I have a Chromebook, which was a $150 laptop. His $300 laptop, which he brings to school every few days, has basically a little bit better specs than mine. However, in a benchmark test, I got 60fps in Minecraft at medium settings, and he managed to get 10fps at the same settings. This "Software Genius" doesn't understand the difference between a heavy OS (Windows) and a light OS (Ubuntu).
Well, anyway, for a bit more back-story on him, he brags about hacking everyone and everything. He also says that he gets hacked a lot too, because he hacks everyone. I asked him one day what he uses to "hack". His response? "Oh, I use a Password Cracker, you can download them like anywhere on the Internet. You have to like complete a survey for it, though." Seriously. Our "Hacker" isn't even using real hacking abilities. Even if password crackers did work, that isn't hacking.

Anyway, so getting to the part where he keeps wiping my SSD-- After school every day, he attempts to steal my laptop and get into it. Luckily, I've set this up to not allow Guest users, and to only allow myself to log in. My password is pretty long and complex, without any real words, and has each character a different part of text. So whenever he gets my laptop, he tries stupid passwords like "I am gay" and "I am a f****t" as if they're going to work, because he's soooo funny. -_-
Anyway, when he gets to the "hacking" he turns the laptop off. When he turns it back on, I make sure to tell him, "Do Not Turn on OS Verification. Press Ctrl+D to Turn it On." Can you guess what he does? He turns OS verification on, because it's "How to hack easier". Anyway, that wipes my entire SSD, uninstalling all of my programs, and Ubuntu, which took hours to install. This is why I'm looking for a lock.
