I Was a Biology Student With No Laptop. I Wrote Code in a Diary. Here's What I Built.

By Arshad Azeez M — Founder & CEO of SidhiLynx, Electronics Engineering student at Anna University, Chennai Let me tell you something that sounds a little crazy. I started learning to code with no laptop, no computer, no system. I was a biology student in 12th standard — not computer science, not engineering. Biology. And I wanted to code. So I did the only thing I could. I wrote code in my diary. Not metaphorically. Literally. Pen and paper. I'd write Java programs in a notebook, then use OCR to extract the text, paste it into Programiz, and run it. That's how I learned. That's how I wrote my first loops, my first functions, my first programs. Did it make sense? Not always. Did it work? Sometimes. Did I stop? No. Why did I even start? I just liked building things.
