Cloud Computing and VirtualizationCloud Computing isn’t virtualization or vice versa but Cloud Computing creates an excellent platform for virtualization. Amazon’s EC2 (Elastic Compute Cloud), for example, is a Cloud Computing environment (as the name implies) built using Xen. Alternatively, Google bases its Cloud environment almost entirely upon physical hardware. Providers who create Cloud-based environments for public consumption, like Amazon’s EC2, will do so using virtualization due to its low cost, flexibility, and high performanRead more...
In the week since the publication of Linux 2.6.27, the kernel developers have already integrated more than 4000 patches into the main development tree of Linux, from which kernel version 2.6.28 will emerge in late December or early January (Linux 2.6.27).In the case of the IDE subsystem, for example, that is essentially matched to parallel ATA, there have again already been many large changes in previous kernel versions (1, 2), although all current ATA controllers supported by the drivers of the IDE subsystem have already long been able to respond to the new Libata drivers.Read more...

After the web learned earlier this week that the final name of Vista's successor was Windows 7, all hell broke loose. The general consensus was that Windows 7 wasn't a bad name, but the reasoning behind it wasn't very clear. Many couldn't figure out how Microsoft had reached the number 7 (I'll give you a hint: they were looking at the kernel version number, instead of counting every single minor and major Windows release). But then others wanted to know why the current builds of Windows 7 were at kernel version 6.1, not 7.0.Read more...

Keeping up with Linux is a time-consuming endeavor. Linux is frequently changing, and it’s so large and widely-used that it is nearly impossible to keep up with all the evolution. With open source communities come power, productivity, and efficiency; so much that it is difficult to know what is happening.In this article, we’ll show you five ways you can keep up to speed with various aspects of Linux. Linux means different things to different people. There are Linux desktops in the home, Linux servers, Linux software development, Web servers on Linux, mainframes running Linux, and the interesting business aspects of Linux. We will try to cover the spectrum.Read more...

Linux® kernel 2.6.25 introduced a new process state for putting processes to sleep called TASK_KILLABLE, which offers an alternative to the efficient but potentially unkillable TASK_UNINTERRUPTIBLE and the easy-to-awaken but safer TASK_INTERRUPTIBLE. TASK_KILLABLE is the outcome of an issue raised in 2002 about the OpenAFS file system driver waiting for an event interruptibly after blocking all signals. This new sleeping state echoes TASK_UNINTERRUPTIBLE with the ability to respond to fatal signals. In this article, the author sheds light on this area and, using examples from 2.6.26 and an earlier version, 2.6.18, discusses the related changes to the Linux kernel and the new APIs that resulted from these changes.Read more...
