I built an open source web calendar inspired by the Google calendar2024 · schedule-x.dev · ▲232I love the looks and UX of the Google calendar. But I wanted to have a version I could use more freely in my own projects, still looking similar to the one from Google.
CodenQuest2024 · codenquest.com · ▲282Hello everyone, I've been working on a project called CodenQuest, a coding practice app inspired by platforms like LeetCode, but with a major twist: it's heavily gamified, similar to Duolingo. The main goal is to make coding practice more engaging, especially on mobile. Key Features: - Diverse coding questions with integrated hints and timers. - Code editor with code completion and fill in the blanks questions - Performance statistics (runtime, memory, CPU usage, and more). - Gamified elements: leagues, ranking systems, daily challenges, friends, and streak mechanisms. - Available on iOS and…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hi HN! I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong. This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code. Happy to answer questions, and please let me know if you have any feedback on the game. Thanks!
