Improve Security on Free Software
I'm relatively new on Free Software, is very dificult to me using free software developing tools because I have learned developing with the Microsoft's tools from the beginning.
Then a teacher showed to us about the free software alternatives for developing and I was interested on them. One of my worries about the free software is this:
If I get for free all the source code of an application (like the database connection, encryptation algorythms, functionality) developed for my clients, everybody could know how this application works and maybe how to hack it!
