Heyyy traveler, Welcome to my page! :^) Here you can learn with me!

Who are you?!

I am a self-taught developer that mostly enjoys electronics, programming, and fixing template-related compiler errors in C++!

I can code very well in C++/C, I am familiar with the x86 assembly (via reverse-engineering), I know a little bit of modern HTML/CSS/JS... and that's about it! I particularly like the GoldSrc engine 🖤 aaand a little bit of other stuff such as cheating, exploiting and software vulnerabilities, and operating systems.

Why does this exist

I created this site in order to educate myself as well as the others, and also to practice my HTML/CSS/JS skills (of course). By writing down about some topic really helps me to understand it pretty well, while possibly educating other people as well.

I mainly post here just some basic articles about stuff I'm currently interested in, or stuff that seems notable. If you want to contact me for whatever reason, you can find contacts on the bottom of the page! Thanks for visiting. :^)
