If we're going to do DevOps, we have to give up open source. Right? Wait, we're an Agile shop, so we have to give that up, too. Right? Over the last five years or so, I've talked with a lot of people confused about what it means to "do DevOps,” and clearly concerned about having to give up other things that have already proven their value in order to adopt DevOps. The bad news is, we've not done a good job in the DevOps community of nailing down what DevOps is and what it isn't at an earlier stage in our development.

“Open source hardware gives people the freedom to control their technology while sharing knowledge and encouraging commerce through the open exchange of designs.” That sentence was taken directly from Open Source Hardware Statement of Principles 1.0, a preamble of sorts located in the definition section of the Open Source Hardware Association (OSHWA) website. Part blog, part doctrine, the site serves as a hub for this ever-growing community of creators.

This guide shows how to remove a failed hard drive from a Linux RAID1 array (software RAID), and how to add a new hard disk to the RAID1 array without losing data. I will use gdisk to copy the partition scheme, so it will work with large harddisks with GPT (GUID Partition Table) too.

In this tutorial we create a combined Openvpn/WiKID server using packer. Packer allows us to create VMware, VirtualBox, EC2, GCE, Docker, etc images using code. Note that combining your two-factor authentication server and vpn server on one box may or may not be the best solution for you.

Shenzhen Xunlong has launched a $59 open-spec “Orange Pi Plus” SBC with a 1.6GHz quad-core Allwinner H3 SoC, 40-pin Pi-compatible expansion, WiFi, and SATA. In December when Shenzhen Xunlong Software announced its open-spec, Linux- and Android-ready Orange Pi and Orange Pi Mini SBCs, both of which use the dual-core, Cortex-A7 Allwinner A20 system-on-chip, the company also briefly noted an upcoming, quad-core Orange Pi Plus. The Plus was said to offer a quad-core, Cortex-A7 Allwinner A31 SoC with a PowerVR SGX544MP2 GPU. Instead, the shipping version, now available at AliExpress for $59, arrives with Allwinner’s new quad-core Cortex–A7 based H3 SoC and a Mali-400 MP2 GPU.

I suspect there are as many Ubuntu-based Linux distributions as there are all other distributions combined. Many of them are designed with a specific purpose in mind. Whether the desire is for a different looking desktop, custom kernel or just pre-installed packages, there's probably a version of *buntu out there to fit every need. Elementary OS is just another in a long list of variants, but what it does, it does very well.

Ramiji, best known for being the first head of Microsoft's Open Source Software Lab, has just been appointed to be CEO of the Cloud Foundry Foundation. I suspect there are as many Ubuntu-based Linux distributions as there are all other distributions combined. Many of them are designed with a specific purpose in mind. Whether the desire is for a different looking desktop, custom kernel or just pre-installed packages, there's probably a version of *buntu out there to fit every need.

Former Unbounded Robotics execs have launched “Fetch Robotics” with $3 million in funding, and will ship a ROS-on-Linux mobile manipulator bot in Q2 2015. A startup called Fetch Robotics has announced $3 million in Series A financing from O’Reilly AlphaTech Ventures (OATV) and Shasta Ventures, along with a development team that jumped from the apparently now defunct Unbounded Robotics. Fetch Robotics plans to announce and ship two mobile manipulation robots in the second quarter that are aimed principally at the logistics and light industrial markets, “as well as for other human-robot collaboration opportunities,” says the company.

Dave Hakkens is the founder of Phoneblocks, an initiative that supports and pursues the creation of modular hardware for cellular phones to reduce electronic waste (e-waste) and increase efficiency. In this interview, Dave shares the story of what brought him to this mission and what he believes the future holds for one of our most treasured devices, the phone.

Data Translation unveiled a Linux-enabled dynamic signal analyzer for measuring noise and vibration, based on a BeagleBone Black-like embedded computer. The DT7837 is used for testing audio, acoustic, and vibration on mobile devices and other electronics gear. The dynamic signal analyzer can simultaneously measure four 24-bit IEPE sensor inputs at a sampling rate of 102.4 kS/s, says Data Translation.

Every year, Opensource.com awards people from our community who have excelled in contributing and sharing stories about open source. These stories are about open source as we use it in our everyday lives as well as how it helps to build a better world and future in technology. This year, we present to you the 2015 Opensource.com Community Awards in the following categories.

Axiomtek’s rugged, Linux-ready DIN-rail PC has a dual-core Atom E3827, remote IoT management, 4GB soldered RAM, and isolated serial, GbE, and DIO ports. Like Axiomtek’s Freescale i.MX287 based rBOX610, the rBOX510-6COM is a fanless, ruggedized DIN-rail computer designed for extreme environments. This time, Axiomtek has turned to the dual-core Atom E3827 from Intel’s most recent Bay Trail-I family of system-on-chips. The 1.75GHz SoC has 1MB of L2 cache, 542/792MHz graphics, and an 8W TDP.

The open source market landscape is growing by leaps and bounds, and it's at a time like this that it's important for Zimbra, a provider of collaboration software, to reinvigorate its open source roots. Here's how we plan to encourage increased participation in community open source projects in 2015.

This article will explain the installation and usage of mytop, a handy tool for live monitoring of MySQL queries. Also looking into various operations that a user can perform while monitoring the queries on mytop.

In the previous tutorial, we demonstrated how to turn a CentOS box into a BGP router using Quagga. We also covered basic BGP peering and prefix exchange setup. In this tutorial, we will focus on how we can control incoming and outgoing BGP prefixes by using prefix-list and route-map.

The Raspberry Pi 2 Model B moves up to a 900MHz, quad-core Cortex-A7 CPU with 1GB RAM, and offers backward compatibility and the same $35 price. The Raspberry Pi Foundation announced a much faster new version of the world’s leading community-backed, hacker-friendly Linux SBC. The Raspberry Pi 2 Model B moves from Broadcom’s 700MHz, ARM11 based Broadcom BCM2835 system-on-chip to a new quad-core Broadcom BCM2836 SoC clocked at 900MHz, and doubles RAM to 1GB.

The design of everyday things is an important cultural movement. Of that, most of us have no doubt. We want our tools to work flawlessly and naturally. And open source projects are catching up on this too.

Here’s three more robots in our guide to the best open source robots. Read part one for the best of the rest.

There are several conferences with a big Fedora presence in the next month. First up, FOSDEM, on January 31st and February 1st. Originally, the name stood for Free and Open Source Developers’ European Meeting, but as far as far as I can tell it’s really just stand-alone word, now — although the conference does have a strong developer audience. I’ll be speaking on Sunday in the distributions devroom (filling in for Stephen Gallagher, who couldn’t make the trip this year). There will also be a Fedora booth — I’ll see many of you there!

I'm not exaggerating when I say that Mozilla's Portland coincidental work week was an example of perfect collaboration between staff and community members.
