The subject of this week's Linux Picks and Pans is a representative of a less well-known computing platform that coexists with Linux as an open source operating system. If you thought that the Linux kernel was the only open source engine for a free OS, think again. The Berkeley Software Distribution, or BSD, shares many of the same features that make Linux OSes viable alternatives to proprietary computing platforms. GhostBSD is a user-friendly Linux-like desktop operating system based on TrueOS, which is based on FreeBSD's development branch.
