Even seasoned system administrators can overlook Linux workstation backups or do them in a haphazard, unsafe manner. At a minimum, you should set up encrypted workstation backups to external storage. But it’s also nice to use zero-knowledge backup tools for off-site/cloud backups for more peace of mind.

Let’s explore each of these methods in more depth. You can also download the entire set of recommendations as a handy guide and checklist.

What Makes Up a Kubernetes Cluster?

Monday 17th of April 2017 03:30:56 PM

In our first three installments in this series, we learned what Kubernetes is, why it's a good choice for your datacenter, and how it was descended from the secret Google Borg project. Now we're going to learn what makes up a Kubernetes cluster.

A Kubernetes cluster is made of a master node and a set of worker nodes. In a production environment these run in a distributed setup on multiple nodes. For testing purposes, all the components can run on the same node (physical or virtual) by using minikube.

  • Top 4 CDN services for hosting open source libraries
    A CDN, or content delivery network, is a network of strategically placed servers located around the world used for the purpose of delivering files faster to users. A traditional CDN will allow you to accelerate your website's images, CSS files, JS files, and any other piece of static content. This allows website owners to accelerate all of their own content as well as provide them with additional features and configuration options. These premium services typically require payment based on the amount of bandwidth a project uses. However, if your project doesn't justify the cost of implementing a traditional CDN, the use of an open source CDN may be more suitable. Typically, these types of CDNs allow you to link to popular web-based libraries (CSS/JS frameworks, for example), which are then delivered to your web visitors from the free CDN's servers. Although CDN services for open source libraries do not allow you to upload your own content to their servers, they can help you accelerate libraries globally and improve your website's redundancy.
  • Users stand up, speak out, and deliver data on OpenStack growth
    Last week, the OpenStack Foundation announced the results of its ninth user survey. OpenStack users responded in record-breaking numbers to participate, and their voices as revealed in the data tell the real story of OpenStack. The OpenStack community is growing, thriving with new users, deployments, code contributions, and collaborations, all on the rise. User diversity is expanding across geographies and organizational sizes. And OpenStack's ability to integrate with innovative technologies is paving the way for advancements not even dreamed of just five years ago.

Debian Derivatives: Q4OS and Devuan

  • Debian-Based Q4OS 1.8.4 Operating System Lets Users Select Alternative Desktops
    Today, April 26, 2017, the developers behind the Debian-based Q4OS GNU/Linux distribution announced the release of the fourth stability and security update of the Q4OS 1.8 "Orion" series. Q4OS 1.8.4 comes almost two months after the release of the previous point release, and besides incorporating all the security patches backported from the upstream repositories of the Debian GNU/Linux 8 "Jessie" operating system series, it adds an exciting new feature, namely the integration of alternative desktop environments.
  • Which is Free, Which is Open … [Also]

    Devuan and Debian need not defer to the Open Source Initiative regarding what is Open Source, since the OSI is just using Debian's Free Software Guidelines. Debian's Free Software Guidelines are a definition of Free Software, not specifically Open Source. At the time they were created, RMS personally approved of them as "a good definition of Free Software".

    A new stable update of the open-source and cross-platform SMPlayer media player was announced recently, versioned 17.4.2, for all supported operating systems, including GNU/Linux and Microsoft Windows. SMPlayer 17.4.2 is now the latest stable release of the popular media player applications, and it looks like it ships with various exciting improvements and new features. One of these is support for using the ffhevcvdpau decoder from the MPlayer project, but only on Linux-based operating systems.
  • Gyazo – An Easy Way to Capture Screenshots, GIFs and Save Websites
    Gyazo is a screen capturing application with which you can quickly take quality shots of your screen and also create GIFs on the fly with a simple click. It is as simple to use as another screen capture tool we wrote on earlier, Peek, but Gyazo seems to have an edge in terms of functionality, customizability, and extension; at least, for now.
