Have fun betting virtual (not real) money on predictions from HN users
I wanted to see how difficult it would be to build a web app using a sub-$300 android smartphone. Decided to build a fun predictions website where you could bet virtual (not real) money on predictions made by others, and also make predictions of your own. Building it turned out to be considerably easier and more fun than I anticipated. Primary tools used were: # QuickEdit as the mobile code editor (Note: the free version of the QuickEdit app is riddled with ads, it shows an advert each time you close a tab, but it unfortunately had the best UI of the 3 or so Android code editors I tested.…
In plain words
This is a prediction betting website where users wager virtual money on forecasts made by community members from Hacker News. Built entirely on a budget Android smartphone using QuickEdit, PHP, and jQuery, the platform allows users to create predictions and place bets against other participants' forecasts. The creator developed it as an experiment to test web app feasibility on low-cost mobile hardware, ultimately finding the process more straightforward than expected.

I wanted to see how difficult it would be to build a web app using a sub-$300 android smartphone. Decided to build a fun predictions website where you could bet virtual (not real) money on predictions made by others, and also make predictions of your own. Building it turned out to be considerably easier and more fun than I anticipated. Primary tools used were: # QuickEdit as the mobile code editor (Note: the free version of the QuickEdit app is riddled with ads, it shows an advert each time you close a tab, but it unfortunately had the best UI of the 3 or so Android code editors I tested. Ended up using NetGuard to block it from retrieving & displaying ads), # PHP for the Backend ( custom PHP microframework I've used and built on over the past few years ). # jQuery for the frontend js (cringing) - it appears I'm simply too lazy to learn React/Vue/et al. Every once in a while, I pick one of them to learn, but I always end up returning to jQuery - or time-permitting - amateur level vanilla JS. # Bootstrap for the CSS - Battle-tested. For a purely backend dev with minimal design skills, good ol' Bootstrap (and in a growing number of cases, Tailwind) is always a life saver. # Whole thing is hosted on 2 VMs (1 hosting the web app, and 1 hosting Redis & MySQL). # As to the site itself, it turned out to be pretty cool to play around with. Go there, view the predictions, bet on the predictions you believe will come true, or against the ones you think will not. You get $50,000 to bet with (not real money). No signup is required to bet, but a quick signup is required to make a prediction. Hope you guys like it, and please be ruthless in telling me of any bugs you've found. So go on here => kudotap.com And Have Fun!

Hey HN! Just for fun, I built an interactive Hacker News Simulator. You can submit text posts and links, just like the real HN. But on HN Simulator, all of the comments are generated by LLMs + generate instantly. The best way to use it (IMHO) is to submit a text post or a curl-able URL here: https://news.ysimulator.run/submit. You don't need an account to post. When you do that, various prompts will be built from a library of commenter archetypes, moods, and shapes. The AI commenters will actually respond to your text post and/or submitted link. I really wanted it to feel…

Hi HN! Excited to show off the project we've been working on for the last couple months. We started with an idea for a crazy twist on prediction markets: You come up with a question for traders to predict, and then decide the outcome yourself. For example, you could create a market on “Will my date with [X] go well?” Anyone can bet on it, and the bets create a forecast on the chance your date goes well. After the date is over, you get to judge the result and reward the traders who picked the correct side. There are so many ways for this mechanism to go wrong: the creator of the market can be…

With my friends we wanted to have a nice friendly competition (no money involved) about the football worldcup by predicting the results. I though this might interest other groups of friends so I coded a website just for that in 3 days. Nothing ground breaking but I like the suscription system "Doodle" style with just links, no personal infos... Tell me what you think !

I made a thing! In 2014, I was holding a stack of iPhones and thought to myself: "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves" I pared that idea all the way down to this: trading cards made of e-ink displays. Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the…
