Father of two here. I started coding in BASIC when I was 8 and fell in love with computers. It evolved into a passion for building products, and it has been my life's career. My son is showing interest in programming, mostly because, like other kids, he wants to make games. That's what got me started, too :) We've been working with Scratch and GameMaker, and I’ve been focusing on fundamentals like logic, structure, and problem-solving. It's really about getting him experience breaking problems

Hey HN, I'm Aline, founder of interviewing.io and one of the authors of Beyond Cracking the Coding Interview (the official sequel to CTCI). We just compiled every problem (and solution) in the book and made them available for free. There are ~230 problems in total. Some of them are classics like n-queens, but almost all are new and not found in the original CTCI. You can read through the problems and solutions, or you work them with our AI Interviewer, which is also free. I'd recommend doing A

I started a little math club in Bangalore. Why Since finishing college a few years ago, studying math has been a mostly solitary pursuit for me. While I enjoy exploring new concepts and solving problems on my own, I often miss the collaborative spirit of my academic days. Back then, my friends and I would gather to discuss homework problems, share insights, and learn from each other. There was a unique joy in exploring ideas together, something that’s hard to replicate alone. I’d love to brin

The original version of this story appeared in Quanta Magazine. They say a bird in the hand is worth two in the bush, but for computer scientists, two birds in a hole are better still. That’s because those cohabiting birds are the protagonists of a deceptively simple mathematical theorem called the pigeonhole principle. It’s easy to sum up in one short sentence: If six pigeons nestle into five pigeonholes, at least two of them must share a hole. That’s it—that’s the whole thing. “The pigeonhol
