In theory, the public cloud is the ideal answer for leveraging extra computing resources when local and private cloud infrastructure aren’t enough. But deploying internal software in the public cloud is much easier said than done. Ravello Systems, however, thinks it has a solution in the form of a hypervisor for your hypervisor. The concept may sound loopy, but it actually represents what could become a crucial new way of taking advantage of virtualization and the cloud.

Users not in possession of root privileges will in future be able to set up containers in which to run software which requires them. Linux 3.8 will, under certain circumstances, use less memory and will include improvements for NUMA systems. Support for Intel 386 chips has been dropped.

Anyone who reads eBooks is aware that a number of content vendors are using proprietary platforms in an effort to lock you into their content libraries. But there is a way out, if enough vendors get on the bandwagon.

Federal Parliament has issued documents formally compelling major technology vendors Apple, Microsoft and Adobe to compulsorily appear before its committee investigating price hikes on technology products sold in Australia, in a move that finally ends months of stalling by the vendors, who have proven unwilling to voluntary discuss their pricing strategies in public.

Computer security is always a concern, network security even more so. Wireless networks are a favourite target for hackers. This is simply because there is no physical link between machines: everything goes over the airwaves. One of the first steps to tightening security is simply to see what the current activity is, and what machines are involved. The tool that should be your first stop is Wireshark.

The open source configuration management framework has moved from Ruby to Erlang for its core API server to enable better scaling and performance

The Kool Desktop Environment, later known as K Desktop Environment or KDE, was launched after Matthias Ettrich issued a call for programmers on de.comp.os.linix.misc in October 1996, and soon had 40 programmers contributing. In the mid Nineties, Linux had X and a variety of diverse and ingenious window managers, but no unified toolkit for the development of applications with a common look and feel. A typical Linux desktop would use a window manager – probably FVWM, which looked a little like Windows 95 – and a scatter of applications, some of which ran in the terminal window while the rest used a variety of widget sets, no two of which looked alike or behaved in the same way.

Linux developer Matthew Garrett, who does a lot of research into UEFI topics, writes in a blog post that by storing a large amount of data in UEFI variables, he managed to disrupt a Samsung notebook running Windows to such a degree that it subsequently refused to start. In his post, the developer also points to some sample code of the Windows program that he executed at administrator level to disable the notebook. The developer had previously speculated that some Samsung notebooks with UEFI firmware may be rendered inoperative under Windows in the same way that they were when starting Linux under certain circumstances. The experiment to confirm this was successful.

If Linux Girl didn't have to spend such a large proportion of her salary dry-cleaning her cape each week, there's no doubt she would invest those extra fortunes in some of the many purveyors of ibuprofen and other pain-relieving medicines. Why? Because of all the headaches FOSS fans are forced to endure here in the Linux blogosphere.

The kernel developers are planning a kernel-based implementation of the D-Bus protocol, which will offer faster communication between system processes and between applications

What excites me about ZWheelz is the potential to improve our education system, environment, energy independence, and economy—all with what I like to call, one "EZ" project. It all began when I built a plane from a kit, then saw the documentary, Who Killed The Electric Car?, and decided to build an electric car. Turns out, it functioned really well, and I began wondering: "Why aren't there more electric vehicles on the road?"

Let’s say it finally happens and the big OEMs get tired of dealing with Microsoft and decide to make Windows only one choice of several on new computers. Not a world like we have now, where the likes of Dell halfheartedly offer half baked and broken installs of Ubuntu, installs that need serious tweaking before they’ll work. Not that world, but a pretend world of Linux being offered across all models, with a choice between two or three distros. You know, OEMs giving Linux exactly the same treatment as they give Windows today.

The mobile revolution has changed user expectations of how they interact with different products. Meeting these changed expectations requires a huge amount of re-thinking from user experience (UX) designers. Pascal Mangold, CEO of Magnolia, recently explored this trend in an article on how the mobile revolution is challenging open source product interfaces and explained how Magnolia CMS, an open-source enterprise-grade Java Content Management System, redesigned its web-based interface to give its users an innovative new "driven by touch" content management experience.

This tutorial explains how you can integrate ClamAV into PureFTPd for virus scanning on a Fedora 18 system. In the end, whenever a file gets uploaded through PureFTPd, ClamAV will check the file and delete it if it is malware.

Chakra 2013.02 'Benz' (a code name that will follow the KDE 4.10 series) has been released. KDE 4.10 is about the most polished release KDE has put out to date; one feature that stands out is the fast improvements of Nepomuk. Our tools have gotten a lot of attention too, the live image has switched to using GFXboot - this will give many more options for language and keyboard settings and it adds a few hardware checking tools in a visually pleasing way.

Thanks to Microsoft's Windows 8 UEFI (Unified Extensible Firmware Interface) Secure Boot there was no easy way to boot Linux, or any other operating system, on Windows 8 PCs. Now, there are two ways, the recently released Linux Foundation (LF) UEFI secure boot system and Matthew Garrett's shim system to boot Linux on these PCs. Soon, there will be only one unified way.
