These differ greatly in the time they support their releases:

* Ubuntu: 18 months
* Ubuntu LTS: Server 5 years, Desktop 3 years
* RedHat, [[CentOS]], Scientific Linux: 7 years
* Gentoo: less relevant; "rolling releases"
* Debian: 1 year after a new release; thus usually 2.5 - 3.5 yrs
* SUSE Linux Enterprise Server: see http://support.novell.com/lifecycle/lcSearchResults.jsp?st=suse+linux+enterprise+server; generally 6 years or more

==Mac OS X==
==Mac OS X==


Mac OS X is a proprietary [http://en.wikipedia.org/wiki/FreeBSD BSD]-unix-derived operating system that runs on Apple's computers. The BSD-subsystem, called [http://en.wikipedia.org/wiki/Darwin_(operating_system) Darwin], attempts to be open-source. Unlike most other flavors of unix, OS X is not based on an [http://en.wikipedia.org/wiki/X_Window_System  X11 windowing system], but instead uses a proprietary [http://en.wikipedia.org/wiki/Aqua_(user_interface) Aqua] graphical user interface. For crystallographers and others who need the conventional X11 windowing system, an [http://trac.macosforge.org/projects/xquartz Xserver for OS X] is available, and installs by default on the most current version of OS X.

==Irix (SGI)==
==Irix (SGI)==
By all accounts, SGIs are now obsolete.  They are more expensive and perhaps offer higher productivity, but it is not worth the money when $500 Linux box takes 1/2 hour to calculate a simulated annealing omit map.  There are some examples of software (such as [http://wiki.c2b2.columbia.edu/honiglab_public/index.php/Software:GRASP GRASP]) that you can only run on SGIs, not Linux.  O is also wicked fast on SGIs.
Irix is a flavor of UNIX and is still supported by [http://www.sgi.com/products/software/irix/ SGI].
