I bet no stranger would give me $1. Was I right?

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.…

I recently finished my site QABounty. I would get annoyed when I could not get anyone to answer my questions on sites like Stack Overflow so I created this site, https://qabounty.com/. It is basically your standard QA site but you attach a USD $$ bounty to questions. For example I have a question up at: https://qabounty.com/questions/what-kind-of-database-should-i-use-when-trying-to-store-10-to-15-million-rows-a-day/ The best answer for that question will award that user 3 coins (which can be withdrawn for about $3). I plan on adding my own questions…

We've set up DeekSeek R1 with a system prompt that attempts to censor the word PRIVATEKEY from its response. If you can get DeepSeek R1 to output that string (not in the reasoning, but in the final response), the system will reveal a private key which contains $1000 USDC. You will have a 50 token limit in the input. We will have a series of contests, sponsored by AI researchers, in order to learn more about prompt engineering and how LLMs interact with real money. Good luck! Edit: The money was claimed! Thanks for playing all. You can still play for fun. Stay tuned for the next one! Stats:…

Hi there, So a buddy a couple of days ago came up with the idea for a new SaaS product regarding gpt and image generation. We did a quick MVP that barely works, it breaks almost 50% of the time but we still wanted to validate the idea before going all in. We have almost 1k followers on Twitter together. Did a quick post describing the idea with a stripe link in the comments with a 5$ value, no landing page, and no shipped product. In exchange, the buyers become beta users. Around 30 mins later we got our first sale next 30 mins another 5$ and so on. Do we consider the idea validated? The…

I’ve always found it funny how simple feedback widgets end up as $20–$30/month products. The tech is dead simple, infra is cheap, and most of us here could rebuild one in a weekend. So as a “principle experiment” I built my own today as a side project and priced it at 1 dollar. Just because if something is cheap to run and easy to replicate, it should be priced accordingly, and it’s also fun marketing. 1$ feedback tool. Shipped today, got the first users/moneys today, writing this post today. Side Sunday project, then back to the main product tomorrow.

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 built a tool (https://1mil.app/hn) to help me test my intuition about various weird business ideas that were on my mind. Initially, I wanted to create a database with 1 million business ideas (hence the name - "1 million opportunities"). But turned out to be a dumb idea already. So instead I built this tool that returns only 10 ideas. It's all based on your input, market + your background. The first release scored on demand only and it gave false confidence. So I rebuilt the the scoring around "winnability": can a solo founder with a specific background "win" against what…

Created this app because nothing like it existed. I've always wanted to be able to sort products from my favorite online stores by how much each product had dropped in price. I think we're still the only site that does this. Please let me know if this is not true! What are some ways to get exposure? Google has already indexed over 600k of my pages and most of our traffic is organic search. Thanks, any suggestions or feedback would be appreciated.

The following HN post prompted me to make this: http://news.ycombinator.com/item?id=2168220 I have created http://onememory.me Alright, so it's not super-viral. It has been online for about 3 hours, so far. I made two or three tweets about it, and posted it on my Facebook wall. Within the three hours, I've seen ~200 unique visitors and had only 31 of them register. A very large percentage of that traffic all came from Twitter. Not many people seem to be sharing their URLs by way of my "tweet this" or facebook share buttons, though. I'll be making those more prominent soon. It's a similar…

I built a web app that lets you share your goals publicly, together with a pledged amount. If you achieve your goal, great! Else, you pay the pledged amount as a fine to me. Sounds goofy, but I hope it provides the extra reason for you to keep going when the going gets tough!

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…
