If your work involves doing stuff through the command line in Linux, more likely than not, you'll be using the Bash shell. Did you know there's an environment associated with the processes that are executed through the shell? And, if you want, you can tweak this environment specifically for the task you're doing? Well, in this article we will discuss a command line tool - env - that not only lets you access the shell environment, but also allows you to make changes to it as an when required.

In July the Atomic Working Group put out the first and second releases of Fedora 26 Atomic Host. This article shows you how to prepare an existing Fedora 25 Atomic Host system for Fedora 26 and do the upgrade. If... Continue Reading →

Axiomtek’s “MANO310” Mini-ITX SBC features the dual-core Celeron N3350 with triple display support and PCIe, mini-PCIe, SATA, and M.2 expansion. Like Axiomtek’s Intel Bay Trail based MANO500, but unlike most Intel Apollo Lake based mini-ITX boards we’ve covered, including DFI’s recent Ali17x, the new MANO310 is not a thin board. However, it targets embedded applications […]

Ask a developer to name their most important tools and very often the reply will include Git. There’s a good reason for that: Git is one of the most widely used distributed version control systems. Git can be set up as a local repository, used on a LAN, or used via the official, global service. With Git you can do things like add access control to your code, display the contents of a Git repository (via the web), and manage multiple repositories.

PolyVection’s “VoltaStream Zero” is an audio streaming SBC that runs Linux on a 996MHz i.MX6 ULL, and offers a TI PCM5121 DAC, TOSLINK, USB, and WiFi. In 2013, Berlin based software developer Philip Voigt decided to build his own music streaming system. As detailed in this blog entry, Voight started with a Raspberry Pi, but […]

As seen earlier this week, the Fedora community holds elections in several groups. One group that elects seats this month is the Fedora Ambassador Steering Committee (FAMSCo). The FAMSCo election started along with others this week. However, due to a technical... Continue Reading →

NextCloud is a free, open source and an alternative to another open source file hosting solution OwnCloud. NextCloud eliminates your need of using third party cloud hosting software like Dropbox for storing your documents. In this tutorial, we will explain how to install and configure NextCloud on Debian 9.

I work daily with content management tools and support documentation writers whose preferred markup language is AsciiDoc. It has a simple syntax, but enough features to keep even a hardcore documentation nerd happy. AsciiDoc allows you to write documentation in a more natural way and mark it up cleanly for presentation on the web or as a PDF. This got me thinking, "Wouldn't it be handy to be able to maintain a website purely with AsciiDoc?" read more

When I started my first company, money was tight. We had a small office and a couple of computers, but not much else. I'd done all my cost planning without even thinking about business licenses and software costs. I know it was a mistake, but it can be easy to treat these sorts of things as an afterthought. read more

The math behind IP addresses is convoluted. Our nice IPv4 addresses start out as 32-bit binary numbers, which are then converted to base 10 numbers in four 8-bit fields. Decimal numbers are easier to manage than long binary strings; still, calculating address ranges, netmasks, and subnets is a bit difficult and error-prone, except for the brainiacs who can do binary conversions in their heads. For the rest of us, meet ipcalc and ipv6calc.

Aaeon’s 10.1-inch “ACP-1106” and 7-inch “ACP-1076” multi-touch panel PCs offer extended temperature, shock, vibration, ingress, and surge protection. Aaeon has updated its ACP line of multi-touch infotainment panel PCs, which include its Bay Trail Intel Atom based ACP-1104, with two new models that run on Intel’s Apollo Lake SoCs. The 10.1-inch, 1280 x 800 ACP-1106 […]

We are quickly entering a world in which you may spend more of your day communicating with robots than with humans. Don't believe me? Ask yourself how many times you've used an automated checkout machine or ATM in lieu of a human, called the 1-800 number for a customer service need and been greeted by a machine, asked Google or Alexa what temperature to roast your brussels sprouts at, or interfaced with a website that gave you a personalized recommendation. read more

In my last few articles, I've looked into machine learning and how you can build a model that describes the world in some way. All of the examples I looked at were of "supervised learning", meaning that you loaded data that already had been categorized or classified in some way, and then created a model that "learned" the ways the inputs mapped to the outputs.

In this tutorial we'll refer to a practical example of Linux dd command that can be used by system administrators to migrate or clone a Windows Operating System or a Linux OS from a larger HDD partitioned in MBR or GPT layout style to a smaller SSD.

Every day, hobbyists and tinkerers are pushing the boundaries of what we can do with low-cost microcontrollers and mini-computers like the Arduino and Raspberry Pi. That trend doesn't stop when it comes to IoT and home automation. In this article, I'll round up six projects from Adafruit Industries that use open source hardware and software to improve home life (or at the very least, make more fun) in new and interesting ways.

There are no negotiated salaries or raises at Basecamp. Everyone in the same role at the same level is paid the same. Equal work, equal pay. We assess new hires on a scale that goes from junior programmer, to programmer, to senior programmer, to lead programmer, to principal programmer (or designer or customer support or ops . . .). We use the same scale to assess when someone is in line for a promotion. read more

Kubernetes is the most popular open-source container manager. It's been officially supported on every cloud platform you've ever heard of... with one big exception: Amazon Web Service (AWS). Now, AWS has got on board the Kubernetes bandwagon as well by joining the Cloud Native Computing Foundation (CNCF) as a platinum member.

Open source software has come a long way since the turn of the century. Every year, more and more people are embracing open source technology and development models. Not just people, though—corporations and governments are exploring open source solutions, too.

Back in the old days, if you wanted to record guitar music at home (or, stereotypically, in your garage), you got an electric guitar (or another instrument capable of making noise, such as a synthesizer), an amp to produce the sound, some effect pedals to customize the sound, and a multi-track recorder such as a 4-track or 8-track recorder. You would plug the guitar into the effects pedals, the pedals into the amp, and the amp into the recorder (or you might mic the amp and record that).
