It's easy to think of containers and VMs as a binary choice -- deciding whether to use a VM or a container (not both) for your use case. In his keynote at LinuxCon Europe, Brandon Philips, CTO at CoreOS, talked about a case study for using VMs and containers together to take advantage of the strengths of both.

In 2014, we called the E-Con Systems eSOMiMX6 computer-on-module “tiny” because it used the 70 x 45mm “?Qseven” form-factor to expand upon the i.MX6 SoC. Now E-Con has bested […]

The gcc compiler offers a seemingly never-ending list of command line options. Of course, no body uses or has expertise on all of them, but there are a select bunch that every gcc user should - if not must - know. While some of them are commonly used, others are a bit uncommon but no less useful.

Over the past six months, federation of Kubernetes clusters has moved from proof of concept to a release that is worth checking.

SiFive’s Arduino ready “HiFive1” dev kit features its 320MHz FE310, the first MCU using the open RISC-V ISA. Also, Samsung is rumored to be using RISC-V. In July, San Francisco-based startup SiFive unveiled the first system-on-chips based on the open source RISC-V processor architecture: a Linux-ready octa-core Freedom U500 and a FreeRTOS-based Freedom E300.

SUSE has become not only HPE's Linux of choice, but it's now its chief cloud developer as well. What it boils down to is SUSE will use HPE OpenStack and Cloud Foundry assets to improve SUSE OpenStack Cloud, and bring to market a new, enterprise-ready SUSE Cloud Foundry PaaS.

In past articles, I've looked at several libraries or specialist applications that can be used to model some physical process or another. Sometimes though you want to be able to model several different processes at the same time and in an interactive mode.

Over the years when using Unix-like systems, I’ve been exposed to three or four different versions of the operating system’s default logging tool, known as Syslog. Here I will look at the logging daemon called rsyslog, a superfast Syslog product.

Shell scripts are incredibly useful things. They allow you to do something as basic as creating an easy command to replace a more difficult one with lots of flags, to batching up many complex commands to run from a cron job. They’re great because you can quickly fire them off in your favorite terminal, but in some cases they require you to remember specific combinations of flags or options. If you find yourself in this situation, you can add some simple GUI dialogs to help you speed your way through the task at hand.
