Hi ErHong! It's always a pleasure to get fresh meat, so welcome to the community!
It would be nice to have new people to work on our projects, or share thoughs about *nix.
You'll find the home of a few open "projects", not all software related (video compilations, Unix diaries, old protocols revival, weekly challenges)...
Some of them might look dead, but all they need is a newcomer to restart it all!
