I just made 4sqvision at SuperHappyDevHouse

4sqvision is a life and fun application launched in 2010. It appears to be a tool or service related to Foursquare integration or visualization, created during a SuperHappyDevHouse event. The product is designed for users interested in location-based social networking features, offering them a new way to interact with or view their Foursquare data. It targets casual users looking for entertaining ways to engage with their social networks and location check-ins.

  Hacky Meta Glasses GPT4 Vision Integration2023 · github.com · ▲226

  v1.0.0: https://github.com/dcrebbin/meta-vision-api/releases/tag/1.0... The previous implementation was very very hacky and used a bookmarklet alongside uglified messenger classes from 2 years ago to monitor a chat, it was also only for image messages. The new release is a browser extension for chrome & firefox that you run on an alt facebook account on messenger that can monitor for new chat & image messages + video monitoring if in a call. You can create a group chat and use a special method (instructions in the readme) to force the Glasses to be aware of…

  floors.jsFeb 2026 · floorsjs.com · ▲215

  Hey HN, I'm Vincent. I built floors.js to bring back social interactions on the web. You paste one script tag. Your pages become isometric 3D rooms. Visitors show up as avatars, see each other, and chat in real-time. Three.js handles the isometric rendering, and a Bun WebSocket server manages presence, rooms and chat. The whole thing runs without touching the host site's DOM or styles beyond its own container. It works on any static site and is also optimised for SPA navigation (clicking on a door lets you navigate to another page). The landing page itself is the live demo, and I'm in the…

  Super Hacker News adds one page browsing & keyboard navigation to HN▲10

  HN has been a destination on the Web for me recently, but I've had trouble really _getting into_ it. I realized that was because there wasn't an intuitive way for me to browse through articles, comments and authors. I started working on a GreaseMonkey script for myself and, as I got into it, decided I would share it with others who may be interested. SuperHN keeps everything on one page and adds keyboard navigation. 'W' and 'S' browse through articles, 'A' and 'D' cycles through an article, its comments and poster. It also makes the front page a bit more readable. You can get Super Hacker…

  TeamPostgreSQL, neat admin interface for PostgreSQL▲10

  I am just getting ready to release TeamPostgreSQL 1.05. You can check it out here: http://www.teampostgresql.com It is a web-based admin interface for PostgreSQL, with a lot of work put into making it a user-friendly and productive way to work with the database.
