Linux kernel 3.0 released

서버(리눅스 vs BSD)

http://en.wikipedia.org/wiki/Usage_share_of_operating_systems

W3Techs(2010.8) 63.7% vs 2.4%
Security Space(2009.7) 74.29% vs 5.35%
Netcraft(2009.1) 41.02% vs 3.30%

슈퍼컴퓨터

Operating system Family share for 06/2011

Linux 91.00 %
Windows 1.20 %
Unix 4.60 %
BSD Based 0.20 %
Mixed 3.00 %
Totals 100%

다 아시는 이야기이지만, 안정성에 문제가 있으면 서버, 슈퍼컴퓨터에 탑재하기 상당히 곤란합니다.
슈퍼컴퓨터 리눅스 점유율 90% 이상입니다.
서버 리눅스 점유율 41~64% 입니다.

알만하신 분이 이렇게 경직된 사고방식을 가지고 계시다는게 좀 신기하네요
게다가 우리나라 인터넷뱅킹이 SSL안쓰는 이유와 같다라니;;; 이건 약간 코미디같고..

우리나라 인터넷 뱅킹은 SSL 사용합니다.
bjy님 유언비어 좀 퍼치지 마세요.

서버, 메인프레임, 슈퍼컴퓨터를 리눅스가 장악하고 있습니다.
군사, 우주, 항공, 은행, 날씨 예측, 과학, 기술 등에서 안정성에 문제 있으면 어떻게 되나요?
전세계가 마비됩니다.

슈퍼컴퓨터에 들어가려면 안정성이 확보가 되어야 하는 것은 당연한 얘기지요.

이로써 리눅스의 안정성은 검증되었습니다.

리눅스 점유율은 두자리 수, BSD는 한자리 수.

Servers

Server market share of software sold through commercial channels can be measured by two methods - market share by units sold or market share by revenue. However, these methods may undercount the share of open source operating systems currently in use, since such operating systems may be obtained for free with or without a support plan and may be loaded onto machines that did not ship preloaded with them.
Another method is to survey publicly accessible servers, such as web servers on the Internet, and determine the operating system powering such servers by inspecting response messages. This method gives alternative insight into market share of operating systems actually installed on those servers, as opposed to the ones sold. This method, however, only includes servers publicly accessible on Internet, and excludes all other servers.

[edit]Mainframes

IBM System z has a 90-95% share of the mainframe computer hardware market.[31]
Operating systems for IBM System z generation hardware include IBM's bundled proprietary z/OS,[31] Linux on System z and as at October 7, 2008; 2 years ago the prototype OpenSolaris for System z.
Gartner reported on December 23, 2008; 2 years ago that Linux on System z was used on approximately 28% of the "customer z base" and that they expected this to increase to over 50% in the following five years.[32]
Of Linux on System z, Red Hat and Novell compete to sell RHEL and SLES respectively.
Prior to 2006, Novell claimed a market share of 85% or more.
Red Hat has since claimed 18.4% in 2007 and 37% in 2008.[33]
Gartner reported at the end of 2008 that Novell had an 80% share of mainframe Linux.[32]
[edit]Supercomputers

Graph of supercomputer OS market share from around 1994 to 2010 according to TOP500.[34]
The TOP500 project lists and ranks the 500 fastest supercomputers that benchmark results are submitted for. It then publishes the collected data twice a year. The June 2011 figures show Linux in the lead at 91%, followed by IBM AIX at 4.2% and Microsoft Windows HPC Server 2008 at 1.2%. A use of mixed operating systems accounts for 3%, and others account for 0.6%.[35][36]

이거 써놓고 다른 글타래 가서 보니..
가짜 전문가 얘기를 다시 꺼내 드는 것 같은데...
그런 것으로 보아서는 이분 맞으신 것 같네요...
