24 alternatives to 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.…
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… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Have fun betting virtual (not real) money on predictions from HN users launched in 2022; newer entries below may have overtaken it.

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…

Hi HN! I’ve been lurking for a while, but out of fear of being steamrolled by HN readers or maybe just natural introversion, I’ve always been too scared to post or comment. Which is why 1. this is my first real Hacker News submission 2. my friend Michael and I built "Fake" Hacker News, a place to post and see what AI-generated HN comments might say. Here’s a video of me using fakeHN to test this very submission: https://www.loom.com/share/4b9f4f9d7c77489a86baeb92ec55a1ed?... And an example of one of our generated posts:…

I've been playing around with Android development recently, and made this Hacker News app this weekend: Market link: https://market.android.com/details?id=com.mellort.hackernews ($1) Dropbox link: http://db.tt/jlqIcBg1 (free: if you like it, DL from the market, too!) I used api.ihackernews.com for the data. Unfortunately, some of the pagination from that source is broken, so I can only return one page of results. In the future, I might play around with creating my own API server on App Engine. I'm not sure what my plans are for the source yet, but I'd like to make it open source. If you're…

Hey HN community, I built a tool that helps optimize your post for hitting the first page of Show HN. How it works: I used a Hugging Face dataset of all Hacker News posts from the past 3 years and trained a model that predicts how successful your post might be. There's still a lot of randomness on HN, so nothing is guaranteed, but the tool helps optimize your post for higher odds. A couple of interesting findings: - GitHub repo links work x3 better than regular domains - Open-source tools have a steady virality rate (13.9% - one of the highest) - "I built" outperforms "We built" - Using…

HN, I've been mostly lurking, semi-active on HN for over 4 years. For most of that time, I've been working on my startup, Learndot. I have always wanted to do a "Show HN" post, but I never thought it was ready. We've now finally launched web signup and using a freemium business model. I feel I can now post and offer something to the community (a new app to try out) and hopefully get good quality feedback. Here's the site: http://www.learndot.com Would appreciate any or all thoughts: From pricing/positioning, to design/performance. The app is written in Sproutcore and backed by an API written…

A year and a half after I published https://HackYourNews.com, I've rewritten it to be neater and added support for more news sources. HackYourNews.com v1 had a great response on HN [1] and consistently sees ~2k weekly unique visitors. There were many long-standing requests that I wanted to fulfill (thanks for your patience!): a proper dark mode, correct rendering on mobile devices, and more cogent summaries. This rewrite is the result. gpt-4o-mini reduces the cost of summarization to an absurd degree, so it's now sustainable to keep this free service going! Someday, I hope to use…

Hi HN, A while ago I had a mildly depressing realization. Back in 2010, I had around $60k. Like a "responsible" person, I used it as a down payment on an apartment. Recently, out of curiosity, I calculated what would have happened if I had instead put that money into NVIDIA stock. I should probably add some context. For over 10 years I've worked as a developer on trading platforms and financial infrastructure. I made a rule for myself - never trade on the market. In 2015, when Bitcoin traded about 300 usd, my brother and I were talking about whether it was a bubble. He made a bold claim that…

I created a bot which analyses Euro 2024 betting odds and performs some basic analysis based on the recent form of each team and provides advice on which odds are under/over-priced by email to all subscribers. The intelligence of the bot is admittedly rather basic but this simple app shows how easy it is to reliably scrape and parse structured data with AI and perform insightful analysis. The initial version of the bot, shown in the notebook took about 15 minutes to build. Disclosure: this bot is built on our new graph based #nocode platform NodeScript.dev, which we've recently brought…

Since the HN devs seem to be in dev-mode, I thought I'd put in one more little request. :) This one line of code, added to the head of HN's html, will make the site actually usable on mobile devices: Here are the before and after pics of the front page: http://imgur.com/rMYfqwN,mwPDMvB#0

http://playbitpoker.com Hey, this is my first startup project and I'm pretty excited. I've got to the point where I feel I've got something solid, and I don't know what to do next. I haven't had masses of people using it and testing it with the test-network bitcoins. I have tested it a fair bit with friends and it seems there's no major problems. What should I do? Is this a minimum viable product? Should I try and promote it while it's still in testing, or should I switch over to using real bitcoins before doing that? I'd love to hear any suggestions you might have. P.S. I had…

Hey HN, After GPT-3 created waves in the tech industry, a lot of AI tools were emerging and with that, some AI website builders But the results seemed way too generic to us. It felt like the developers were rushing to catch the wave instead of building a proper tool We took our time, did months of RnD and finally came up with something better than what others in the market are doing. It’s got better design output. While it’s still in beta, I wanted to show HN what we did. Will appreciate the feedback when you guys try it out. Here is the link to signup for the beta:…

Yesterday I decided I wanted to experiment with different ways of reading HN. After considering a few options, I settled on a Mac app and spent a couple of hours planning/sketching on paper. This morning I fired up Xcode and spent 4 hours hacking away and I must say I'm liking how it's looking. Since the project is in its very early stages, I though that it could be a very good time to get some feedback. I've posted a few screenshots at http://imgur.com/a/rCbVN and uploaded a binary at http://abra.rm-fr.net/~fiam/HackerNews.zip If you have some free time, give a try and let me know what you…

I have recently developed a bot capable of simultaneously scanning over 140+ sportsbooks around the globe. It analyzes millions of odds in real time and uses this data to find overpriced odds. The logic behind it is straightforward: it uses odds from all sportsbooks to calculate the probabilities of an event occurring. Then, with simple maths it determines if the expected value is positive, meaning the potential payout exceeds the risk. Unfortunately, sportsbooks limit your accounts once they realize that you are profitable and not a losing customer. So I have already been limited at more…

Hi HN, I love building small games (as Pong, Wordle, Tetris, etc.), but they're never quite unique enough to justify their own site. So I built boring.game - a daily "boring" game where the social mechanics (predicting your score, challenging other users) is more interesting than the game itself. I started a HN team if you want to compare your results: https://boring.game/invite/SRhyUStjin You can also play all daily games without signing up, if that is what you prefer. Built with SvelteKit (first time using Svelte - loved it!). Would love feedback on both the concept and…
