This hands-on class provides experience with a variety of Linux virtualization approaches. We examine the straight forward approach of creating VM's with tools like the virt manager and virsh and then dive into qemu and KVM.
This class covers Linux virtualization from the introductory level up to a more advanced level. Not only covering “how to” but also the “how” of how things work behind the scenes. How virtualization is implemented on Linux. From the role of qemu to the role of the Intel and AMD specialized instructions.
National Council Of Education, Research and Training (NCERT) has released a notification on their website which promotes the use of Free and Open Source software in Indian schools. This notice is released well in time, as other schools, colleges and government institutions in India are already moving to open source software to save costs and prevent vendor locking. NCERT is responsible for maintaining standards in most government and private schools and educational institutions in India.
It sounds like Microsoft is working on a dual-boot smartphone strategy that would cover both Google Android and Windows Phone. Um... this strategy sounds a bit like the 1990s, when IBM launched a dual-boot initiative involving OS/2 and Windows. Anybody else remember how that story turned out?
Today's news scan turned up several interesting entries. First up is Linux.com's piece highlighting three key moments in Linux history. A new Scientific Linux review is out. Two KDE release announcements were posted. OMG!Ubuntu! has a list of seven features you're going to love in Ubuntu 14.04. A new Linux bug is wreaking havoc. And finally, friends don't let friends operate Windows.
While many developers are jumping on board with Linux, odds are that porting their old titles is not likely to occur, whether due to cost, resources or perceived lack of interest. This issue can be solved by either “going native”, only running software that is available natively for Linux, or by employing an option such as Wine to get it to run under Linux. Another option includes virtualization, but that is beyond the scope of this article.
The bug in the GnuTLS library makes it trivial for attackers to bypass secure sockets layer (SSL) and Transport Layer Security (TLS) protections available on websites that depend on the open source package. Initial estimates included in Internet discussions such as this one indicate that more than 200 different operating systems or applications rely on GnuTLS to implement crucial SSL and TLS operations, but it wouldn't be surprising if the actual number is much higher. Web applications, e-mail programs, and other code that use the library are vulnerable to exploits that allow attackers monitoring connections to silently decode encrypted traffic passing between end users and servers.
I think computers like Chromebooks are the way of the future, but not because of their operating system - because of their hardware. Relatively low cost laptops with SSDs for storage and an insane battery life are everything I want in a computer.
The code, set to be released in March, doesn't patch kernel code in-place but rather uses an ftrace-like approach to replace whole functions in the Linux kernel with fixed variants, said Pavlik. SUSE then plans to submit it to the Linux kernel community for upstream integration.
Today KDE released the second alpha of Frameworks 5, part of a series of releases leading up to the final version planned for June 2014. This release includes progress since the previous alpha last month.
Early last year, I posted a piece on Mozilla radically changing its approach to plugins in the Firefox browser. Plugins and extensions are, of course, part of the reason why many of us chose to use Firefox in the first place. There is a huge ecosystem of useful ones. However, especially since Firefox moved to a rapid release cycle, extensions have cause many performance problems. For that reason, Mozilla has been steadily overhauling its process of handling extensions in Firefox, especially when it comes to extensions that are automatically enabled.
With the open-source graphics driver stack found in the forthcoming release of Ubuntu 14.04 LTS (Mesa 10.1 + Linux 3.13), the performance of the community-developed Radeon Gallium3D driver is now close to that of the official AMD Catalyst driver for recent generations of Radeon graphics cards. In several OpenGL tests the "RadeonSI" driver can even run 80% the speed of AMD's official Catalyst Linux driver.
There are several definitions of open source. The Open Source Initiative (OSI) website contains a very useful and detailed definition, which goes beyond access to the source code and includes ten specific criteria concerning the distribution terms of open-source software. We will not enter here into the ongoing debate concerning the differences between open source and free software, as the OSI website provides a short review of the terms.
Magiea has been one of my favorite projects and distributions since its inception, but Jesse Smith said today that the spell is broken for him. Smith had issues with his network connection upon first boot, but continued to have installation and updating of software issues. He complained of poor performance, missing packages, and a seriously annoying task switcher too. All in all, he wasn't pleased. He concluded (in part):
For those who do not know, Nokia uses its own proprietary fork of Android, rather than stock Android, in its X-series devices. It also removes all Google services and replaces them with its own. Therefore, these devices ship with Nokia Store in lieu of Google Play. However, ports have been made in both directions, i.e., Google apps on Nokia X, and Nokia Store on other Android devices.
Today KDE released updates for its Applications and Development Platform, the third in a series of monthly stabilization updates to the 4.12 series. This release also includes an updated Plasma Workspaces 4.11.7. Both releases contain only bugfixes and translation updates, providing a safe and pleasant update for everyone.
Like All Things Open, which is now an annual event, Great Wide Open is aimed at those who earn their living by plying their trades in the tech sector. In other words, don’t expect any workshops or presentations on “How to Setup Ubuntu for Grandma” here. However, this doesn’t mean there’ll be nothing for people who mainly use Linux and open source at home. Indeed, all FOSS supporters should look into enterprise events like this because what happens in the enterprise often eventually ends up on the desktop, either as improvements/additions to Linux or as new open source applications.
The module is available in an industrial temperature version. It ships with a Yocto Project-certified Linux Linux 3.12 or 3.2 BSP that offers a choice of several distributions, including Arago and Ubuntu. Board support packages are also available for Android 4.x and WEC7.
My own talk was about where KDE, both technically and socially/organizationally, is going, also resulted in quite a few questions. They ranged from "what does RTFM mean" to discussions about involvement of startups and decision making processes. Much of what I talked about won't be new for KDE people who follow what is going on in our community quite closely. I mostly extrapolate from trends which have been visible for quite a few years. But for those who are new or less close to our community, I plan on putting it in a blog post or two over the coming days/weeks.
NanoPC launched a $69 mini-PC and $67 SBC based on a quad-core Samsung Exynos4412 SoC, with SD, HDMI, USB, camera, and Ethernet, and running Linux and Android.
The team is proud to announce the release of LMDE 201403.
