Commercial software houses tend to base development on a rigorous policy of quality assurance, source and revision control systems, documentation, and bug reporting and resolution. Developers are not allowed to add features or to change key sections of code on a whim: they must validate the change as a response to a bug report and consequently “check in” all changes to the source control system so that the changes can be backed out if necessary. ” Internally, the quality assurance department runs rigorous test suites (so-called regression tests) on each new pass of the operating system and reports any bugs.
A great number of web and FTP archive sites carry Linux software and related documents. Appendix A contains a listing of some of the Linux documents available via the Internet.

There are tons of TCP/IP-based applications and protocols out there. If you have experience with TCP/IP applications on other systems, Linux will be familiar to you. The system provides a standard socket programming interface, so virtually any program that uses TCP/IP can be ported to Linux.
