• What is Automation and Configuration Management with CHEF – Part 1

  Configuration Management is the key focus point of DevOps practice. In the Software development cycle, all the servers should be software-configured and maintained well in such a way that they should not make any break in the development cycle. Bad configuration Management can make system outages, leaks, and data breaches. Using Configuration Management tools is about facilitating accuracy, efficiency, and speed in the DevOps-driven environment. There are two models of configuration Management tools – PUSH-based & PULL-based. In the PUSH-based, the Master server pushes the configuration code to the servers wherein PULL-based individual servers contact the Master for getting configuration code. PUPPET and CHEF are widely used PULL-based models, ANSIBLE is a popular PUSH-based model. In this article, we will see about CHEF.

What is GNU/Linux Copypasta?

I’d just like to interject for a moment. What you’re refering to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX. Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux!

Ben Widawsky: Framebuffer Modifiers Part 1

In a now pretty well established tradition on my part, I am posting on things I no longer work on! I gave a talk on modifiers at XDC 2017 and Linux Plumbers 2017 audio only. It was always my goal to have a blog post accompany the work. Relatively shortly after the talks, I ended up leaving graphics and so it dropped on the priority list. I'm splitting this up into two posts. This post will go over the problem, and solutions. The next post will go over the implementation details.

Linux Lite 5.4 Will Be Based on Ubuntu 20.04.2 LTS, Release Candidate Ready for Testing

Linux Lite is a user-friendly distro that aims to bring more ex-Windows users to the Linux and Open Source ecosystem. The new release of this Ubuntu derived distribution, Linux Lite 5.4, will be based on Canonical’s recently released Ubuntu 20.04.2 LTS (Focal Fossa) operating system. But Linux Lite 5.4 will ship with the long-term supported Linux 5.4 LTS kernel instead of the much newer Linux kernel 5.8 from Ubuntu 20.04.2 LTS. However, users will be able to install any other kernel they want up to the recently released Linux kernel 5.11 from the software repositories with just two commands.
