Show HN: I created a ninety second challenge for conversations that matter Hello HN, AskPitch Duel is an exciting challenge where you can choose one of three scenarios from a Busy prospect to a Tough interview or a Business pitch and then have a tough conversation with that character giving you a score, you will then share a link provided to you to challenge anyone you wish and send them that link which will have them against the same character and when finished, will be shown a score to see who won! The first duel doesn't require any sign-up and is extremely simple to use! Further i created the main platform AskPitch out of a true pain point that i had come across in which i had to pitch to clients over a sales call, give presentations, talk in public, handle objections in a way where i had to speak in the correct tone with confidence and know what to say while handling objections with ease. AskPitch allows its users to practice in a practice room to optimize their delivery, tone and confidence as well as a Live Roleplay area where users can have 1-1 conversations with a number of characters available for them to choose from where they can further better their pitches. There are a lot of areas in which a person needs to be good at while pitching. I had all the issues mentioned above and did not know what to say under pressure or when face to face with a prospect, and imagine the horror when i had to speak in front of a crowd. This is where AskPitch was born, I created it to help me with my pitches, my delivery, my tone, my confidence and soon i noticed i started getting positive feedback from the people i was speaking to, i noticed the butterflies in my stomach were noticeably fading over time, i noticed that i was smiling more often when meeting with clients, whether face to face or through a call and soon enough, i saw myself becoming good and becoming better like i was being optimized. I knew i found something and realized that there are many others just like me who have the same issue as i previously did and this could most definitely help them in a very positive and progressive way and so i started building AskPitch for people to practice and use while they're out and about or while they're at home or right before a pitch or even right before an interview! AskPitch allows its users to practice from a variety of scenarios such as: Insurance call opening Busy Prospect Objection Difficult client conversation Explain your business Job Interviews Investor Pitches Presentation Warmups Stage Talks Thank you and i hope you find this as useful as i did. https://ift.tt/6MDefv1 July 7, 2026 at 11:01PM

Show HN: A free, GPU-accelerated Texas Hold'em GTO solver in C++/CUDA https://ift.tt/ZbhEg5w

Show HN: A free, GPU-accelerated Texas Hold'em GTO solver in C++/CUDA I built this mostly because I love the intersection of game AI, high-performance computing, and poker. I’d love for anyone interested in game theory or CUDA optimization to tear it apart, test the accuracy, and give me feedback. Happy to answer any questions about the algorithms, the transition from CPU to GPU, or poker AI in general! https://bupticybee.github.io/texassolver_gpu_page/ July 7, 2026 at 04:52AM

Show HN: Open Science, open-source alternative to Claude Science https://ift.tt/yWYd8wf

Show HN: Open Science, open-source alternative to Claude Science Claude Science just launched. It’s a sign AI research is moving toward centralized, closed systems. So we built the opposite: Open Science: a local first, model agnostic AI research workbench. MIT licensed. Fully open. Fully reproducible. https://ift.tt/rdDCbmj July 6, 2026 at 02:13AM

Show HN: I made the Chrome Dino Game editable by your AI prompts https://ift.tt/lQXAoWO

Show HN: I made the Chrome Dino Game editable by your AI prompts In 2024 Google Labs released GenDino: a version of the Chrome Dinosaur Game that let users turn prompts into skins. GenDino is dead. The Dino Game happens to be OS, so I forked it and created Vibedino to let your prompts change the actual game. Make the dino front-flip every time it jumps. Add a hard mode after 1000m. Break my backend by implementing the full PageRank algorithm. Give it the dumbest feature idea you can think of and then approve it yourself to deploy to the main site! https://vibedino.com July 6, 2026 at 02:11AM

Show HN: I hated how much my 12-year-old played Roblox, so we built our own FPS https://ift.tt/hyJrbMQ

Show HN: I hated how much my 12-year-old played Roblox, so we built our own FPS I'm a father of two, 7 and 12. They are obsessed with Roblox, especially Rivals. Like a lot of parents, we did not love it. We tried the usual things: block it, limit it, set timers." It became a daily battle, a lose-lose situation. So I flipped the problem. Instead of fighting what they loved, I decided to lean into it, but with a twist. Why just play an FPS when you could build one together? My kids became the PMs. Claude and I became their engineer. I was shocked by how fast we moved. We picked a name, Cooked and started building. Get in. Lock in. Get cooked! In the first 3 hours, we had an actual FPS we could play together in the browser. Next day I invited my friend's two kids over. Suddenly, I had four PMs. We had 3 laptops, 1 iPad and 1 iPhone. So in 30mins we added mobile support and could play all 5 together. The kids would ask for features: "Can we have a rocket launcher that knocks people off the map?" "The knife should stab faster when you hold it." I know almost nothing about FPS design, so they were the experts. They explained what they wanted. We turned that into prompts. Claude would implement it. We would reload the page and play it 10 mins later. It's the most fun I've had building software in years. My kids are proud of it. # Here's how Cooked is cooked. The architecture - It's just a web page. TypeScript + Three.js. - No game server. Multiplayer runs over a P2P WebRTC mesh. - Supabase is only the matchmaker. It handles presence and the WebRTC handshake. - It is very cheap to run. Static site plus a few Cloudflare edge functions for TURN relay. - Bots fill empty rooms. Each bot gets a random loadout and play style. # What worked and what didn't I have been writing software for 20 years. For the last 9 years, as CEO of Krisp.ai, I have not had much time to program myself. I missed it. Claude changed it. I obsessed with this side project for the last 2-3 weeks. First, building a project with your kids is a great way to bond. It gives you shared interests and real quality time. Second, I wanted to understand the limits of Claude today and how we can apply this at Krisp. This helps me stay grounded. Opus 4.8 is extremely good at architecting application systems, researching references, and implementing algorithms. I would tell it things such as "research how the weapon system is designed in Roblox, Diablo, Fortnite and come up with a proposal on how to do this in Cooked". It would come up with an impressive backlog and I would just say "Go". Where it was really weak was UI design. It simply couldn't detect/see obvious design problems. I’ve tried to implement a loop with a game designer agent, UI designer and system architect. While the research, reasoning were top-notch, the system failed due to bad design taste and the inability to see images properly and spot problems there. Interesting fact. It really failed miserably when I challenged it to design and draw "hands" that hold the weapons. I also have struggled with building decent maps. It lacks imagination and fails even after providing a lot of guidance. Another interesting fact. This morning, I gave the same problem of “drawing a hand” to Fable and it drew it from first-shot, for all weapons. Very impressive. # Why I'm sharing this Two reasons. One: if you're a parent fighting the same screen-time battle, consider flipping it. Building the thing they love, with them, turned a source of conflict into a shared creative project. My 12-year-old now understands feature scoping. My 7-year-old has strong opinions about explosion sizes. Two: AI coding tools have crossed a line. A dad who is not a game developer, together with four kids, built a real multiplayer browser FPS that their friends actually play. https://cooked.house July 5, 2026 at 02:14PM
