Linux-based AUV maps Antarctic sea ice thickness

26 11 2014

Woods Hole Oceanographic used a Linux-based “SeaBED” AUV to build the first 3D map of Antarctic sea ice — and found it’s thicker than had been estimated.

Like the Bluefin Robotics Linux-based Bluefin-21 AUV, which was used in an unsuccessful search for missing Malaysia Airlines Flight 370 earlier this year, the SeaBED surveys the surface (or in this case the ice) in lines, like a lawnmower. The SeaBED was specially fitted with an upward-looking sonar device to measure ice thickness.

SeaBED runs Ubuntu Linux on a 1.2GHz Intel Pentium. Complete source-code is provided to users, “making sensor additions or vehicle maintenance much simpler than that of competing commercial offerings,” according to Singh’s SeaBED page on the WHOI website.

The electronics are located in the top hull, and the batteries and sensors are in the bottom hull. The two hulls are connected by “wet” cabling routed through the vertical struts, says WHOI. The upper hull holds most of the positive buoyancy while the lower hull houses the bulk of the negative buoyancy, thereby increasing stability in pitch and roll conditions.

” Linux is Everywhere. From Space Stations to Microwave Ovens, Linux powers everything.” You might have heard that a lot and have always wondered ” Is that just a phrase or is it actually true ? “  Be assured, it is true. World’s biggest companies use Linux in one way or another but you are not going to believe unless I take names.

The Halloween Documents: Microsoft’s Anti-Linux Strategy 15 Years Later

31 10 2013

It’s almost Halloween—which marks 15 years since Eric S. Raymond published the first leaked “Halloween Documents” documenting Microsoft’s (MSFT) secret strategy to compete with Linux and open source. A lot has changed since then, when terms such as “fear, uncertainty and doubt” (FUD) first exploded into the lexicon. But how much remains the same? Do Microsoft and open source play nicely today?

The Halloween Documents, so-called because the first one leaked in October 1998, don’t actually have much to do with Halloween itself—which I find sad, as an avid fan of the holiday. But for understanding the historical relationship between Microsoft and open source, the memos are vital.

They were the first to reveal the particularly nasty “tricks” Microsoft planned in its effort to contain the open source movement, and to prevent Linux in particular from cutting too deeply into its revenue. One key strategy for the company was implementing proprietary protocols to lock customers into Microsoft software. Another was touting Microsoft software as offering lower total cost of ownership (TCO) than Linux, even though the documents showed that Microsoft itself found Linux to be the cheaper overall solution in many cases.

History, however, has proven Microsoft’s strategy largely wrong. Fifteen years after Raymond published the first of the documents (he subsequently added several more to his site, along with extensive commentary), which Microsoft later acknowleded to be authentic, Windows and Linux continue to coexist. And while Linux and open source never became an existential threat to Microsoft, as the Halloween Documents suggest executives at the company once feared, it’s hard to deny that they have significantly curtailed the company’s share of important markets, like servers operating systems and applications, for many years. Microsoft might be a richer enterprise today if it had achieved the goals it articulated in the Halloween Documents.

French police move from Windows to Ubuntu Linux

7 10 2013

Summary: The big reason the French Gendarmerie made the Linux move? It saved them 40 percent in total cost of ownership over Windows.

There are many reasons to switch to a Linux desktop from Windows. Better security; not having to worry over possible built-in privacy leaks; and, last but never least, Linux is cheaper… a lot cheaper.

That’s the big reason why the Gendarmerie, which with the Police Nationale, serves France as a national police force, has been slowly, but surely moving to a customized version of Ubuntu Linux, from Windows XP.

In an European Union report for government administrators, Major Stéphane Dumond of the French Home Office is reported to have said at the Evento Linux conference that, “Using an open-source desktop lowers the total cost of ownership (TCO) by 40 percent in savings on proprietary software licenses and by reducing costs on IT management. Using Ubuntu Linux massively reduces the number of local technical interventions.”

Kubuntu Linux Emerges From Ubuntu’s Shadow

5 09 2013

The KDE desktop variant of Ubuntu Linux gets its own commercial support as it begins life away from Canonical.

Thanks to support vendor Emerge Open, the Kubuntu Linux distribution now has its own commercial support for those users and enterprises that need or want it. Kubuntu is the KDE desktop version of the Ubuntu Linux distribution that is commercially supported by Canonical. The primary Ubuntu Linux distribution is based on the GNOME Linux desktop.

“Canonical used to provide a commercial support service for Kubuntu but dropped it last year,” Kubuntu developer Jonathan Riddell told eWEEK.

Riddell explained that Kubuntu is one of the flavors of Ubuntu and, along with the flagship Ubuntu Desktop, it gets server infrastructure to build packages and host Kubuntu distribution.

No End in Sight to Linux’s Reign in the Top500

19 06 2013

Linux’s many strengths are undeniable in numerous aspects of computing today, but if there’s one area in which its domination tends to continue virtually unchallenged, it’s supercomputing.

Last November’s Top500 list was a perfect illustration of that ongoing reign and now the latest version of that list brings even more good news for Linux fans.

Linux took more than 95% of the top500 supercomputers list.

Linux continues its domination of the Top500 supercomputer list “with all of the top 10 and more than 90 percent of systems relying on clustered Linux,” said Jay Lyman, a senior analyst for enterprise software at 451 Research.

Most notably, in the 41st Top500 list, which was announced Monday at the 2013 International Supercomputing Conference in Leipzig, Germany, Linux’s share of the world’s fastest machines had increased yet again by more than another percentage point to 95.2 percent.
