I hear a lot about security problems, any hints on secure programming?
Even though at the start you may think that your programs on your little non-networked Minix system will never be a security threat, it is a good idea to learn a little bit about secure programming early in your programming career. Two useful references are the Secure UNIX Programming FAQ maintained by Thamer Al-Herbish, and the Secure Programming for Linux and Unix HOWTO by David A.
