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!

Good math problems are hidden inside textbooks and online documents. To keep up with all the sources in the world is hard. For someone who just wants to continuously solve problems, finding and going through all the sources feels like a hassle. I wished for a website that could just dump all the math problems available in the world out there. And if I could filter the problems by topics, that would be beautiful. teachyourselfmath is a side project that was born out of this need. At its core, it is a math PDF extraction engine. The engine has some machine learning going on behind the scenes…

I had an idea for this concept for a while and decided to build a little website around it. It's kind of a silly idea but I'm really curious to see how it plays out. If you're a particularly curious person, be warned. By submitting a payment to the game, you get to see how many other people were curious enough to play. You will be ranked based on your payment amount, and get to discover some interesting insights about the game's dynamics. Hope you like it

My dad makes the questions, I made the site. I think the genre and the level of difficulty is suited for HN. Hope you enjoy. (I promise no AI-generated questions, they are all hand made!).

www.schmeebs.com I built this site in two days. I tried to make it a fusion of Twitter + Digg in that people will be able to follow certain "domains" of news then be able to see popular stuff from there. Its as real time as it can be at this point. Would welcome any thoughts on it!

Hello all, I built about 2 years ago a coding website for kids, teens and adults: https://codeguppy.com Despite my efforts to promote the website it is still not well know. I post almost daily about it on Twitter at https://twitter.com/codeguppy ... but even there I don't have views. The website is fun... although I still have a ton of things to add. I appreciate if you take a look and suggest improvements and most importantly help me with spreading the news about this website. I really need a boost! Thanks all!

I haven't seen anything like this so I decided to build it in a weekend. How it works: You see a bunch of things pulled from Wikipedia displayed on cards. You ask yes or no questions to figure out which card is the secret article. The AI model has access to the image and wiki text and it's own knowledge to answer your question. Happy to have my credits burned for the day but I'll probably have to make this paid at some point so enjoy. I found it's not easy to get cheap+fast+good responses but the tech is getting there. Most of the prompts are running through Groq infra or hitting a cache…

Well HN, I've finally produced something I think is worthy of sharing, but I didn't do it "in a weekend". Yeah, it's an iOS puzzle game. And yeah, it's a game I built because I wanted to play it rather than based on market research, so all this sort of makes it the antithesis of a popular HN post. But whatever. Still hoping for some of that patented (har har) expert HN feedback. Critique any part of it except the music. Also, PM me for upgrade codes, or I can post some here if there's any interest. Download (it's free):…

Hi Hn, A buddy and I worked on this prototype to see if we could design a system that helps people think creatively. I'd love your feedback, tips and pointers - and yes, I know it's a bit ugly (much css work to be done). Check it out at beta.monsterlumen.com and let us know what you think!

Link: http://this.isby.us/ I've been working on this on and off for a few weeks as part of an apprenticeship program with a Rails shop. I was given the opportunity to create a 'toy' app to learn more about Rails development. The basic idea is this: If you know people you often share links with, you can create a 'bin' on the site, and share that bin with others. Then, you and your friends can all add and view links that you find interesting. My goal was to make this happen as simply as possible, so there are no user accounts, and there is a bookmarklet for adding links without having to go…

Hi HN! In the last couple of weeks I've been working on Cranki: Cranki = Crosswords + Anki. (It's a stupid name tbh, haha) I like doing crosswords in Spanish (to learn vocab) but none of the apps out there allowed me to use my own list of words that I come across. So I built one instead. It's entirely client-side. No server, no database, no accounts, etc. Your words and stats are stored in local storage. I built this for myself but let me know if you like it!

Hi, I spent the last couple of months developing OurClubFundraiser(http://www.ourclubfundraiser.com) and launched it about two weeks ago.I would love to get some feedback from the HN community on how I could improve the site and tweak the concept. Since launching I have found that: 1) I am not getting enough visits(Average around 5 a day) 2) Any of the visits I do get are not converting. I am working on 1) and will hopefully be able to dramatically increase the number of visits over the next few weeks. I could really do with some third party perspectives on point 2. 1)Is the concept not…

It has: War Alliances Presidents Voting for community leaders No users and much more... I made this because I'm terminally online and I'm hyper interested in online communities, how they function, how they evolve and this is basically my bet in the direction that it's all going in. That bet is that online communities will evolve to require much stronger tools to enable mass collaboration, democratically elected leaders/moderators and the war thing is just for fun.

linkrdr (www.linkrdr.com), a personal link aggregator, was directly inspired by http://news.ycombinator.com/item?id=3555923 I read while browsing on HN. It's still a bit rough, but the concept is an interesting one and people have already shown interest. Let me know what you think. Also, if anyone knows a good UX designer, email me :)

Here is the link: http://www.wikihowtodo.com I know a lot of geeks share the same dream -- build the next kick-ass todo-list/project management system. So do I. However, as I was quite positive that my web development skill is worse than 99% of developers' in this community, I decided to build something simple, useless but unique. So I built this. Basically it's a Wikihow scraper, nothing more. It gives you a place to store interesting Wikihow articles and yes, they are converted into todo lists. I know this site is not that good, but I still need your guys' feedback. For example, as I am a…

For fun this Valentine's Day, a couple buddies and I decided to play around with the idea of digital Valentines. We cranked out the project in the month of January as a "nights & weekends" project. We'd love any feedback in general! Our next step is to figure a way to seed this in key communities, to see if it has any chance of taking off. The URL is www.1millionvalentines.com (or www.1MVS.com). Thanks!
