The other day I got a fantastic idea on Electrical Technology. I had envisioned a solution to problem that has challenged me from my college days. I contacted my professor and was convinced my idea was unique. This was the time I was using Kubuntu OS. I was able to better use my PC due to the fact that some one, somewhere, totally unknown to me has put in hours of work so that I and fellows like me could run my computer without burning our pockets. Without such great souls, my use of my computer would have been hampered by proprietary software.
At that moment I was in the state of dilemma. If I get a patent, I have chance of getting money. If I declare my works as GFDL in public domain, some can use it and I wont be rewarded properly. Declaring my works in a public domain would surely help some one trying to build a project cheap and might remove R&D burdens being enforced on customers pocket.
Finally I added a copyright saying, any one who wants to use my work should contact me. If any one uses it for a good purpose, I will give certain rights for free, else if the person is trying to make money by using derived version of my work, he has to pay a share of profit.
Very soon I will put my work under GNU belt, so that all can use it without paying me a paise.
