I should have included more detail in my last post. For those who do not know, open source (GPL) licensing states that if I distribute a program called Hello_World under an GPL license, anyone can add, modify, or create the source code for Hello_World as long as the modifications are added to future versions of Hello_World and follow the original GPL license restrictions. For instance, you could not modify Hello_World and create your own version called My_Hello_World and distribute it as a competitor to my version. The legal implications of GPL licensing are way to complex to write about in this email; however, Linux, Apache and Netscape are some high-profile examples that have been successfully disturbed under GPL. In my last post, I referred to a program called Samba. Samba is an open source software application that provides seamless file and print services to SMB/CIFS clients. Samba is BIG in the Unix world right now and there are allot of contributors to it because Samba fills a very important void in Unix networking. Obviously if Samba was written in Ada, you would need to know Ada in order to write the modifications you wanted to add to it. My theory is: If one or more Ada programmer(s) saw another big void in the Unix/Linux world and realized an application in Ada under GPL to fill it, there would be such an interest in the application that people would learn Ada in order to contribute to it.
