In plain words

This is a development tool that helps programmers understand the Monty Hall paradox through code. It provides executable examples and simulations that demonstrate why switching doors increases winning odds in the classic probability problem. The tool is designed for developers and students learning probability concepts and computational thinking. It's hosted on GitHub for easy access and contribution.

    A variant of the Monty Hall problem (the 7th one on this quiz) went semi-viral a couple months ago. For me at least, I may be able to walk through the reasoning of the original problem, and I may be able to convince myself it's correct, but it's very hard to build an intuition for why it's correct that feels truly sound. So I thought it'd be interesting to have a quiz to contort the original problem in as many ways as possible to challenge my understanding and intuition. Try it out!

    I made a puzzle game that gently introduces my favorite math mysteries2024 · rahulilango.com · ▲1,054

    This is the first iteration of a short game I’m making that tries to interactively explain some of my favorite math questions / ideas. My goal is mostly to get the player curious and not necessarily to explain absolutely everything. There were a lot of fun technical parts to building this: - For implementation reasons, it’s much easier if the lines all have integer intersection points with each other. To do this, when a new line is added I “cheat” by rounding intersections to integers and then splitting the old lines at the intersection into new linds (with potentially different slopes)…

    I learned about the Monty Hall Problem recently. I thought it was so interesting it inspired me to make this small interactive website about it.

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
