The Art of Overthinking Everything

23.06.2025
I overthink. A lot. It’s practically a hobby at this point. I’ll replay conversations in my head like a director trying to fix a scene that’s already happened, plan imaginary arguments I’ll never have, and stress about things that probably don’t matter. Some people call it ex...

Binary in a Nutshell

Explaining how Binary works

13.01.2025
What is Binary? Binary is a number system that uses only two digits: 0 and 1. This system is called “base-2,” compared to the decimal system (base-10) we commonly use, which has digits from 0 to 9. Computers use binary because electronic circuits only have two states: on (1) ...
