"Nmap ("Network Mapper") is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping)."

"Last year, I wrote an article describing the free and open-source graphics stack, explaining all of the interconnected pieces: X11, graphics drivers, DRM, and DRI, and their roles in getting pixels placed on the screen. In the year since, I've answered a lot of really good questions from the Linux community about my post, about X11, and about Wayland. I've learned a lot. Several new technologies have appeared, and I have started to take a more active role in this myself, as part of our efforts to port GNOME to Wayland."
