All modern operating systems are able to run many programs at the same time. For example, a typical Linux server might include a Web server, an email server, and probably a database service. Each of these programs runs as a separate process. What do you do if one of your services stops working? Here are some handy command-line tools for managing processes.

Steve Mills, the senior vice president and group executive of IBM’s software group, talks about the benefits of open source software, Web 2.0 tools for business, and taking programming for granted: “Open source has been a great help to us, because it helps accelerate standards. You get significantly improved interoperability and portability. I think where people misunderstand this is that it’s often not the money you make from the open source code; it’s the money you make around it.”
