  Hello 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…

  I spent 4 months building Duolingo but for your life2025 · three-cells.com · ▲90

  I initially released this as just an IOS app. Since then it has been growing steadily but a lot of people have emailed asking for a web / android version. It took me nearly 2 months to build a version for the web. The nice thing about using Convex as my backend is that all the data is always synced between the app and web. I do not have to setup any syncing logic. The moment you change something in the app, it will reflect on the web version in realtime. I know there are loads of these kind of tools online but it's starting to feel like mine is actually starting to differentiate itself…

  Talanoa▲346

  Hi 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…

  22 GB of Hacker News in SQLite▲730

  Community, All the HN belong to you. This is an archive of hacker news that fits in your browser.

Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
