A desktop app for keeping diary, my second GUI program. The project is still active, because I'm using it.
A proxy (similar to shadowsocks-dotcloud). My initial motivation is to use free PaaS to host it, and fix some weakness of shadowsocks (which *may* help GFW to discover server). But actually it's just a reinvented wheel.
Toy Scheme Interpreter.
My first Android app, a live wallpaper. It's an abandoned prototype, because I'm short of original color scheme and filters. And a nice filter is so complex. It's sad to find out that I forgot some basic syntax of Scala after few months of not using it.
