]]> Comment on Auragen computers remembered by Stu Green http://www.yodaiken.com/2006/03/auragen-computers-remembered/comment-page-1/#comment-1286 Stu Green Fri, 06 May 2011 15:55:21 +0000 http://yodaiken.com/?p=32#comment-1286 I too was at Auragen briefly and was one of the commuters from NYC. It was a fantastic learning environment with substantial Unix knowledge being freely shared by folks like Anita Borg. Unfortunately, it did not last long enough. Doug Wells was one of the greatest sources of networking and Unix internals knowledge I have ever met. To close the circle following Auragen's demise I joined Bell Labs and finally got to see viable fault tolerant Unix at Tandem. I too was at Auragen briefly and was one of the commuters from NYC.

(Just an example Google's entire infrastructure is missing from those market share numbers, I'd say that makes them questionable) It looks like MS got those numbers from Gartner which wikipedia says is based on 'Revenue' so Linux will be very underrepresented http://en.wikipedia.org/wiki/Usage_share_of_operating_systems#Servers Netcraft says Windows and Linux are both about 41% (and Apache is almost 90%...) https://ssl.netcraft.com/ssl-sample-report//CMatch/osdv_all The market share for Linux on servers is almost certainly severely undercounted since they ONLY count stuff like RHEL where you have a support contract involved (ie where there’s some sort of ‘sale’) The problem with doing this is that that’s not the only way Linux is deployed to production environments, people frequently just install debian or some other distro after downloading it themselves.

For bashscripts it is very useful, though.
