I have seen many people write plugins or some small application on github and people using it. Do they get paid for it ?
Some example i saw were :
2) Markdown parser which github uses
3) language parsers
4) Games strategy eg .playing with computer
people have implemented many things some of which may be directly taken from some research work
I guess most of what one thinks is already there.
Just want some idea from experts how to go about getting such ideas where to look at some magazines, sites etc. so that one can pick up a small project by oneself and build something useful for people.
