This is the fourth in a series of articles on systems administrator fundamentals. These days, DevOps has made even the job title "systems administrator" seems a bit archaic like the "systems analyst" title it replaced.

I've been using the lm-sensors tool ever since CPUs became hot enough to melt themselves. It monitors CPU temperature, fan speeds, and motherboard voltages. In this two-part series, I'll explain some advanced uses of lm-sensors, and look at some of the best graphical interfaces to use with it.

The actor and founder of HitRecord Joseph Gordon-Levitt kicked off the second day of the Open Source Summit. His open creative community, HitRecord, allows for the evolution of open source film projects. We learned how a company is using BlockChain to fight poverty while keeping plastic out of the ocean, and about how Microsoft and Google are now more deliberate about how they create a culture of openness inside and outside their companies. Watch as Jason Hibbets and I give you a quick summary of day 2, and I manage to understand what TensorFlow is along the way. read more

WebERP a complete web based accounting and business management tool that can be used for online shop or a retail management system released under an OpenSource license. In this tutorial, I will show you step by step how to install WebERP on Ubuntu 16.04 server.

In this article, Ciarrai Cunneen and I describe how to do a paper-based usability test, using an early redesign of the GNOME Settings app as an example. The updated Settings features in GNOME 3.26, released on September 13. When writing open source software, we often obsess about making our logic elegant and concise, coming up with clever ways to execute tasks and demonstrate ideas. But we sometimes forget a key fact: Software is not useful if it is not easy to use. read more

And then filtering out all the stuff he doesn't need to read Emacs enthusiast Artur Malabarba has put the text editor to work taming Slack.…

The Mirai botnet attack that enslaved poorly secured connected embedded devices is yet another tangible example of the importance of security before bringing your embedded devices online. A new strain of Mirai has caused network outages to about a million Deutsche Telekom customers due to poorly secured routers.

Machine learning and artificial intelligence (ML/AI) mean different things to different people, but the newest approaches have one thing in common: They are based on the idea that a program's output should be created mostly automatically from a high-dimensional and possibly huge dataset, with minimal or no intervention or guidance from a human. Open source tools are used in a variety of machine learning and artificial intelligence projects. In this article, I'll provide an overview of the state of machine learning today. read more

Google's top-of-the-line Chromebook Pixel is coming back with a new name and better specifications.

Wi-Fi is one entry-point hackers can use to get into your network without setting foot inside your building because wireless is much more open to eavesdroppers than wired networks, which means you have to be more diligent about security.

Unikernels are small and fast and give Docker a run for its money, while at the same time still giving stronger features of isolation, says Florian Schmidt, a researcher at NEC Europe, who has developed uniprof, a unikernel performance profiler that can also be used for debugging.

In Linux, there's a concept of users (those who use the system), and then there's the concept of groups, which is basically a logical mechanism to manage a collection of users. To give you a basic idea, groups make it easy to manage users with, say, same security and access privileges.

Firefly’s “RK3399 Coreboard” compute module features Rockchip’s hexa-core RK3399 with up to 4GB RAM and 16GB eMMC, and is supported with a new dev board. Firefly has taken the guts of its Rockchip RK3399 based Firefly-RK3399 SBC and squeezed it onto a computer-on-module.

According to Droid Life, on October 4, Google will release the first new retail version of the Chromebook Pixel since 2015, the Pixelbook. The Chomebook Pixel was the Rolls-Royce of Chromebooks. It was faster, more powerful, and came with a better display than any other laptop in its day. Thanks to Chromebook Pixel fans, Google has elected to start selling this luxury Chromebook again.

For years I've been jealous of folks with iOS devices who could just send their phone screens to their Apple TV devices. It seems like the Android screen-mirroring protocols never work right for me. My Sony Xperia has multiple types of screen mirroring, and none of them seem to work on my smart TVs or Roku devices.

Octavo’s OSD335x-SM is a 40 percent smaller version of its AM335x based OSD335x SiP that adds an EEPROM and more I/O. There’s also an open-spec dev board. Last year, Octavo Systems added a new twist to BeagleBone development when it released its 27 x 27mm OSD335x System-In-Package (SiP) module. The OSD335x, which went on to […]

Pipewire — a new project of underlying Linux infrastructure to handle multimedia better — has just been officially launched. The project’s main goal is to improve the handling of both audio and video. Additionally, Pipewire introduces a security model to... Continue Reading →

Abstractions and metadata are the future of architecture in systems engineering, as they were before in software engineering. In many languages, there are abstractions and metadata; however, systems engineering has never adopted this view. Systems were always thought of as too unique for any standard abstractions. Now that we’ve standardized the lower-level abstractions, we’re ready to build new system-level abstractions. read more

The Linux Foundation is highlighting some of those who have recently passed the certification examinations. In this article, recently certified engineer Georgi Yadkov shares his experience.

Adlink’s MVP-6010 and MVP-6020 embedded computers run Linux or Windows on Intel 6th Gen CPUs, and offer 4x PCI/PCIe slots, 6x USB ports, and 4x COM ports. If Adlink’s new MVP-6010/6020 Series looks familiar, that’s because it’s a modified version of the recent MVP-5000 and last year’s MVP-6000 industrial PCs.
