A simple postgres client I'm working on in my free time: https://sanchosql.com/
Linux only now but it's open source so it should be possible to compile for win/mac
Never planned to make any money out of it, I've made it because I needed it, and to play around with building a unix tool in C. It's pretty simple but it's definitely one of the projects I've had the most fun working on and I still have plenty of things I want to add.
1) online platform for learning foreign languages via simple games, currently trying to make it work on mobiles (http://language-monster.com)
2) attempting to create a classic 2D real-time strategy game, although it's in early development: https://github.com/lchsk/knights
I intend to make it work on Linux & Windows
It's got a fairly nice GUI and allows you to script events in a scripting language that's like a mix between Python and C++. You can also just use C++. Everything works as part of a "scene-tree". The physics and rendering engines are swappable. I believe it uses SDL2 by default. I'm pretty new at game-dev stuff. Most of my work is in back end web development. I just thought you may find it interesting or helpful.
Thanks. Don't know of anything made specifically for learning Chinese unfortunately, but I do hope to extend my project to include Asian languages someday.
Thanks! It's written in C for the reason that I want to become a faster C developer. It hasn't always been the most convenient experience but I sure get better in writing C :).
I'm currently battling with the Microsoft Winrt driver but I'd love to see this happen on Linux too.
I guess the driver would use Chromium Embedded Framework.
Contributions on that would be more than welcome.
