Windows "Windows is indeed slower than other operating systems in many scenarios, and the gap is worsening." That's one way to start an insider explanation of why Windows' performance isn't up to snuff. Written by someone who actually contributes code to the Windows NT kernel, the comment on Hacker News, later deleted but reposted with permission on Marc Bevand's blog, paints a very dreary picture of the state of Windows development. The root issue? Think of how Linux is developed, and you'll know the answer.

This is total propaganda and I am sick of it. Windows is BY FAR the fastest OS. Linux is absolute junk. While the Linux kernel may be OK...and I stress may be OK... let us not accept such things on blind faith... Linux as a complete operating system is total garbage.

International Space Station to boldly go with Linux over Windows

Computers aboard the International Space Station are to be switched from Windows XP to the Linux operating system in an attempt to improve stability and reliability.

Dozens of laptops on the ISS's 'opsLAN' network - which provides the ship's crew with vital capabilities for day-to-day operations, from telling the astronauts where they are to interfacing with onboard cameras - will be switched, removing Windows entirely from the ISS.

“We migrated key functions from Windows to Linux because we needed an operating system that was stable and reliable – one that would give us in-house control. So if we needed to patch, adjust or adapt, we could," said Keith Chuvala of the United Space Alliance, which runs opsLAN for NASA.

Astronauts using the system were trained on specific courses tailored by the non-profit Linux Foundation.

Linux is already used to run various systems aboard the ISS, including the world's first 'Robonaut', sent to the Space Station in 2011. 'R2' can be manipulated by astronauts as well as ground controllers and is designed to carry out tasks "too dangerous or mundane" for astronauts in microgravity, according to the Linux Foundation.

Tailored versions of Linux are widely used in scientific projects, including CERN’s Large Hadron Collider.

How Linux Mastered Wall Street

When it comes to the fast-moving business of trading stocks, bonds and derivatives, the world's financial exchanges are finding an ally in Linux, at least according to one Linux kernel developer working in that industry.

This week, at the annual LinuxCon conference in Vancouver, Linux kernel contributor Christoph Lameter will discuss how Linux became widely adopted by financial exchanges, those high-speed computerized trading posts for stocks, bonds, derivatives and other financial instruments.

As an alternative to traditional Unix, Linux has become a dominant player in finance, thanks to the operating-system kernel's ability to pass messages very quickly, Lameter said in an interview with IDG. In fact, the emerging field of high-frequency trading (HFT) would not be possible without the open-source operating system, he argued. Lameter himself was hired as a consultant by one exchange -- he won't say which one -- based on his work in assembling large-scale Linux clusters.

IBM, Intel and Linux dominate Top 500 supercomputer market

In terms of operating systems, 462 out of the 500 supercomputers on the list use Linux, 25 run on Unix, and just 13 are based on Windows.
