Im working on a mind mapping app that would allow for integration of gamification features and be nicer and easier to remember. I was missing more advanced graphics from apps and being able to treat it as my note taking and learning tool. i.e. how (and why?) should I remember a mind map if it looks the same like all other maps and all i can do is pick couple of shapes and dashed/dotted lines? this simply doesnt work with my brain so i decided to create something better :) map on page is a preview of this, but im curious about the quiz, typing games and cheatsheet, would love some…

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…

I built a daily puzzle where a piece of paper is folded and hole-punched, and you predict where all the holes end up when it's unfolded. It's the kind of thing I used to do in grade school with actual paper and scissors, and it turns out the mental version is a surprisingly good spatial reasoning challenge. Three difficulties each day: easy is a 4×4 grid with one fold, hard is 6×6 with three folds. It's built with Next.js. The puzzles are generated deterministically on the fly using a daily seed. The engine runs a forward simulation of the paper folds using 2D coordinate mirroring, then…

One true story, one lie — the room votes. A live icebreaker

The idea is simple: click any place on the map, propose a name, others vote, or it will be auto-accepted in ~5min. No account needed for fresh locations or name duel - only to challenge already-renamed places or vote to prevent abuse. 40k renames so far, and surprisingly people mostly behave. Some names are genuinely creative and I keep learning random geography facts just by watching the map (did you know someone mapped every single animal in a Taiwan Kaohsiung zoo on OpenStreetMap?) Non-commercial, just a side project. Stack is SvelteKit, MapLibre, 40GB vector map self-hosted on Cloudflare…

A "marbles-based" puzzle game, feels a little bit like pool, and a little bit like breakout, but it has its own flavor. Three worlds of linear gameplay in single-player mode, with a total of 36 levels, which the player can solve either by a few quick trick shots, or with a patient step-by-step approach. Shared screen mode to play against a friend. Our first title, feedback appreciated. This is the "lite" version, completely free, no ads. The full version has 5 worlds and 200+ levels. https://play.google.com/store/apps/details?id=com.apsisware.pinchoomarbleslite

Finding the balance between humans and machines has been the thread through my career. I always had a thing for AI and couldn't wait for it to actually deliver on what was promised. Now it does, and it's more important than ever that humans and machines keep working well together. AI makes creation trivial. Text, code, design, strategy, in seconds. But one thing AI does not create: independently verifiable proof of when something existed. Reproducing is now cheaper and easier than creating. Chronology becomes contestable at the moment it matters most. The universal problem was known. I…

hi all. i’ve been shipping a small open project that tries to answer that question with evidence, not vibes. in 70 days it reached \~800 stars. the core claim is simple: many AI failures are not noise. they repeat because the geometry and ordering underneath are stable. if so, we should be able to name each failure mode, set acceptance targets, and stop shipping the same bug twice. ### what it is * a compact Problem Map of 16 reproducible failure modes in RAG and agents. * each item has a minimal fix and measurable gates. examples: * Semantic ≠ Embedding: metric and normalization mismatch.…

Hi everyone, I’m a student with a strong interest in computer science and complexity theory. Recently, I worked on a manuscript attempting to prove that P ≠ NP. I know how this sounds — it’s one of the hardest and most debated problems in CS, and many have tried and failed. I don’t claim to have the final answer, but I believe the approach I used might at least offer some fresh perspective or provoke useful critique. The idea involves geometric separation between deterministic and nondeterministic computation, using high-dimensional lattice constructions and some physics-inspired intuition.…
