Linux Distros

"5 Rock-Solid Linux Distros" is an InfoWorld article by Serdar Yegulalp and reads as follows:

"Here we look at five major Linux distributions from the developer’s point of view and how they shape up to meet a developer’s needs. All of these are major, mainline projects, with years if not decades of user support and development behind them. There’s little risk in making any of them the basis for one’s development environment.

That said, each of these distros—Ubuntu, Mint, Fedora, CentOS, and OpenSuse—has different strengths and weaknesses, and each balances the needs for flexibility, ease, and stability in its own way. Depending on the balance you seek, you will undoubtedly be drawn to some more than others."

DistroWatch.com is a site that lists links to BSD and just about every Linux distribution. But more it also tracks specific packages used by BSD or Linux.
