Is the Raspberry Pi ready to take over the low-end thin client market? This week, NComputing unveiled the RX-HDX, its second Raspberry Pi based thin client.]

Have you ever heard someone say, "It's impossible to do X with Linux"? Me too. This is the story of how I busted the myths about open source in my own head and used Linux to finish my PhD in fine arts. Many people think non-technical students can't use Linux, and they make a lot of assumptions about people who use it in their advanced degree programs. They scoff and reply with something along the lines of, "Well, of course; those people do 'computer stuff,' but in my [lofty, important, unique area] it's just not possible." Well, it is possible, and I'm proof. read more

From prohibition-era moonshiners to the 2000s MTV classic Pimp My Ride, people have repairing, upgrading, and modifying their cars for a long time.

The $70 “Waggle” remote controller device for 3D printers offers a mobile app with a video feed and temp controls, plus a cloud-based slicing service. A Seoul-based startup called Ateam Ventures is closing in on its $10,000 Kickstarter goal for a Waggle 3D printer controller equipped with WiFi and a 720p video camera.

The alias command-line tool is both useful and relatively simple. Its purpose is to simplify a single-line command by creating a custom name for it. There is a good chance that you already have some aliases even if you've never used the tool. In Bash, aliases can be created with a simple text editor and are stored in your $HOME/.bashrc file. If you want to see what aliases have been set up, take look at that file, or simply type alias on a command line and press Enter/Return. read more

Ladies and gentlemen, we've left Mars. Well, at least I'm done with the Martian lander from my past few articles. I hope you had chance to experiment with it and find out that it's not too easy to land a craft on any planet!

"A good engineer is a lazy engineer," some will say. And to a certain extent, it's true: Laziness is a great quality if you're automating repetitive tasks. But laziness flies in the face of learning new technologies and getting new work done. Somewhere between Junior Systems Administrator and Senior DevOps Engineer, laziness no longer becomes an advantage. Let's discuss the five laws aspiring DevOps engineers should follow if they want to become great DevOps engineers. read more

Adlink launched a rugged, Linux-ready “MVP-5000” industrial PV with 6th Gen Core processors, up to 32GB DDR4 RAM, and mini-PCIe based wireless options. The MVP-5000 is a close cousin to last year’s MVP-6000, the first in Adlink’s “value line” series of rugged, fanless MVP computers, which offer much of the functionality of its MXE line […]

DevOps is mostly about culture change. Being successful is all about finding ways to bridge the gap between the builders and the maintainers, bringing projects to fruition and updating them in shorter cycles to maintain a competitive advantage. But at the end of the day, you need the right tooling to make it all work. read more

Elementary OS, my dear penguin? With the death of Unity, Canonical will focus more attention on Ubuntu servers, Ubuntu in the cloud and Ubuntu in the so-called Internet of Things.…

Windows will almost certainly never be open source, but virtually all Microsoft Windows engineers are now using the open-source program Git to build Windows on.

MinnowBoard.org’s “MinnowBoard Turbot Quad” and Aaeon’s UP Squared SBCs began shipping, featuring community sites and Intel SoCs running Linux and Android. On May 23, Intel-backed MinnowBoard.org and ADI Engineering began shipping the first quad-core MinnowBoard, selling for $190.

Joining any new company—with an established culture and programming practices—can be a daunting experience. When I joined the Ansible team, I decided to write up the software engineering practices and principles I’ve learned over the years and to which I strive to work. This is a non-definitive, non-exhaustive list of principles that should be applied with wisdom and flexibility. read more

At one point in time, when you wanted to attach an external block storage device to a server, you mapped it as a Logical Unit (LU) across a Storage Area Network (SAN). In the early days, you would do this over the Fibre Channel (FC) protocol. More recently, iSCSI (SCSI over IP) has usurped FC in most data centers.

As we mentioned in the previous article, web browsers present the largest and the most exposed attack surface on your Linux workstation. We’ve already discussed some best practices that Linux sysadmins can follow to reduce the impact of a compromised browser, such as upgrading to Wayland, using a different browser for work/high-security sites, and using Firejail to create a sandbox around Linux applications.
