    Project mention: Show HN: Word Wolfers, Number Wolfers – educational games inspired by Munchers | news.ycombinator.com | 2025-11-03

    Hi HN! I just shipped a handful of educational games playable in your web browser. I hope you will give them a try and consider sharing them with the students in your life. I labeled each game with the target grade level (from TK up through middle school, and even high school for Spanish).

    I've wanted to bring this style of educational game back to life for a long time.

    In the early 90s, my grandmother had a Macintosh with educational games. She was a teacher who specialized in teaching reading. She showed me how to play Word Munchers and I had a blast munching words with the right vowel sounds.

    Wolfers games should look good on phones, iPads, and can also be installed as progressive web apps on your home screen. I recently found a simpler way to make PWAs thanks to this minimal-pwa[0] project (via HN). I made this a bit more dynamic and self-contained in Wolfer's pwa.js and added offline PWA support in sw.js. I go as far as to dynamically generate the icon for each game variant using JavaScript. I didn’t realize browsers supported this!

    I shared more development details and links to the source code here[1].

    Project mention: Show HN: Turn an audio recording into a LinkedIn video – no signup, no server | news.ycombinator.com | 2026-03-07

    I am working on some bigger projects and wanted to start sharing them on LinkedIn and YouTube. The problem is you can't just post audio on LinkedIn, it needs to be a video. Every tool I found for this wanted a signup or a subscription, and none of the demos looked how I wanted anyway.

    So I just built one with Claude. It runs in the browser, nothing gets uploaded anywhere. It is a single HTML file. A bit janky but it does what I need.

    If you are on the job market or building something new and want to share your voice without being on camera, maybe it helps you like it helps me. If you think something could be improved, reach out.
