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.

The holiday season is upon us, bringing its special brand of festive chaos to many of our lives. Although this time of year can be a bit busy, many technologists still find the time to hone their skills by participating in a technical holiday calendar.

A keynote at the Embedded Linux Conference Europe described Greenlight for Girls, which aims to give girls around the world the opportunity to love STEM. There is growing anxiety within tech companies about the lack of skilled professionals to keep up with demand. There’s also a realization that one of the largest untapped resources is […]

During my career I have spent a lot of time packaging other people's code, writing my own, and working on large software frameworks. I have seen projects that still haven't released a stable version, never quite hitting 1.0, while others made 1.0 releases within months of beginning development, and then quickly moving on to 2.0, 3.0, etc. There is quite a variance in these release cycles, and this coupled with maintaining large projects can make things difficult. read more

As we saw in the previous article, the TCAM (Ternary Content Addressable Memory) in a traditional networking switch is the cornerstone of the Data Plane's operation. The foundations of SDN lie in the following question: What if we could access or program these remotely? We will discuss the consequences and effects next.

All the buzz these days is on microservices, those emphemeral flashes-in-the-pan that appear and disappear on demand, thousands or even millions of times per minute. Chauhan discusses the importance of changing the way we develop network services to support microservices.

Gitlab is a web-based management and collaboration software for GIT servers similar to GitHub. It contains features like issue tracking, file browser, change tracking and a project wiki. In this tutorial, I will install Gitlab CE on a Debian 8 server behind a Nginx proxy. The Nginx proxy improves scalability and security of the system.

In the June 2016 issue, I described my Raspberry Pi outdoor camera build. Since then, however, I've discovered a different way to stream video from it.

Open leaders are systems thinkers. When they look at the world, they see a series of dynamic relationships—between people, teams, and resources. These relationships are the elements that are always in motion, always in flux, and ultimately drive the success (or failure) of our businesses. read more

With more than 10 million units sold, the Raspberry Pi is a massive success. At this year's All Things Open, community manager Ben Nuttall gave a five-minute lightning talk introducing the educational charity behind the popular mini computer. read more

This is the time of year when Linux distribution releases start to slow down (just a bit), but there have been several noteworthy recent releases to recognize before 2017 starts.

In the pre-cloud days we saw virtualization take hold where entire operating systems were portable inside of virtual machines. That way a machine could move from server to server based on its compatibility with hypervisors like VMware, KVM or Xen Project.

In this week's edition of our open source news roundup, we take a look at open source virtual reality, a new board for electronics testing, Fedora 25, and more. Open source news roundup for November 20-28, 2016
