Modern hypervisors enable efficient resource sharing among multiple guest operating systems by virtualizing and emulating hardware resources. However, such virtualized resource sharing may not always be desirable, or even should be avoided when VM performance is a great concern, or when a VM requires full DMA control of a hardware device.

It's been a very long time coming, but GNOME has finally hit its stride--in a big way. Since the release of GNOME 3, people have declared that this particular Linux desktop is dead. Those naysayers can now put their hatred aside and enjoy the hard work that the developers have put into making GNOME 3.16 the single most polished iteration of this open-source desktop to date... and quite possibly any Linux desktop.

When I heard Erica Stanley speak about women in open source at All Things Open last fall, I knew I wanted to hear more. When the opportunity to interview her arose last month, I jumped at the chance. read more

The sound of a dying hard drive can be terrifying. It means a headache, downtime, and replacement costs in the best case. In the worst case, it means sending the drive to a data rescue lab. Using a redundant array of independent disks with mirroring (RAID 1), you can make a drive failure less of a nightmare.

It’s no longer April Fools Day, so what we are about to tell you is no joke, but the real deal. The awesome developers behind the well-known and acclaimed Magic Lantern third-party software add-on that brings a wide range of new features to Canon EOS cameras, have announced that they’ve managed to port the Linux kernel to Canon DSLRs.

Google announced an Asus “Chromebit” HDMI stick running Chrome OS, plus four new low-cost Chromebooks, and opened its Android-to-Chrome OS app porting tech. Google took the Linux and Chrome browser based Chrome OS a step closer to a potential convergence with Android as it announced the first embedded form-factor Chrome OS computer, as well as […]

It's been a unique experience for me as a Techdirt writer, one who does not delve into the net neutrality debates and posts very often, to watch the effect the wider coverage about net neutrality has had on the general public. Without being scientific about it, there are certain markers for story penetration I notice and have noticed specifically when it comes to net neutrality. For instance, a couple of months ago, my father called me up with a simple question: "What should my position be on net neutrality?" The question itself isn't generally useful, but the simple fact that a grandfather is even asking about it means something...

Only a couple of days after releasing the final build of the Firefox 37.0 web browser, Mozilla has now pushed the next major version of the application to the Beta channel. We were very curious to see what’s new, so we have downloaded Mozilla Firefox 38.0 Beta in order to report its new features and improvements.

Nebula, which provided OpenStack-based private cloud solutions, has closed, suggesting that only more established companies will now succeed in the OpenStack market.

Google has extended the support for its ARC Welder app and now Linux users can also run Android apps (APKs) right in their browser, with just the help of a downloadable Chrome app.

If you've spent any time around UNIX, you've no doubt learned to use and appreciate cron, the ubiquitous job scheduler that comes with almost every version of UNIX that exists. Cron is simple and easy to use, and most important, it just works. It sure beats having to remember to run your backups by hand, for example.

By design, the research company’s numbers don’t reflect the amount of money spent by U.S. taxpayers funding the NSA’s operations. Nor do they indicate how much of this $47 billion is being born by the likes of Microsoft and Oracle, as far as I can tell. What I do know is that many foreign governments have been publicly investing in Linux and open source projects since Snowden’s revelations that back doors for the NSA have been built into many proprietary U.S. enterprise software products.

This article provides a detailed analysis about the new Advanced Encryption Standard (AES) built-in functions provided by IBM XL compilers. It explores the code that the compilers generate to demonstrate the performance gained by using the built-in functions. This is critical for high-performance AES applications, especially when many of them cannot be parallelized due to the nature of operation modes, such as chaining mode [for example, cipher block chaining (CBC) and propagating cipher block chaining (PCBC)] or feedback mode [cipher feedback (CFB) and output feedback (OFB)]. If you are a software engineer who is interested in achieving high performance for applications on IBM POWER8 processors, this article is for you.

The stable edition of Ubuntu 15.04 (Vivid Vervet) is just around the corner, so this is a good time to take a look at the features that are going to be implemented in the new release and see what important packages have been updated.

This document describes the basic installation of a CentOS 7.1 server. The purpose of this guide is to provide a minimal setup that can be used as basis for all kind of CentOS server setups.

Could Microsoft's open source advocacy ever result in the company offering its cash cow Windows OS up to open source? It's possible, according to one Microsoft official, though his comments Wednesday should perhaps be taken with a grain of salt.

The Document Foundation announces LibreOffice 4.4.2, the second minor release of the LibreOffice 4.4 "fresh" family, with over 50 fixes over LibreOffice 4.4.0 and 4.4.1.
