In this tutorial, I will show you how to install Rails on CentOS 7. We will install and configure Ruby on Rails with a PostgreSQL database, and then create our first project with Rails. Ruby on Rails (RoR), or short "rails", is a server-side web application framework written in ruby that follows MVC (Model-View-Controller) concept.

How does an open organization make decisions when stakeholders have contradictory priorities? And what if safety and human life are two of those priorities? In such a scenario, it seems that maximizing safety would supersede any other agenda, but engineering has a long history of failures that show otherwise. With their emphasis on open communication and clear guidelines, open organizations can help ensure those responsible for decisions avoid such failures. read more

In this series, we'll put together a nice reliable configurable mail server with Postfix, Dovecot, and OpenSSL on Ubuntu Linux.

In his talk, Joe reminded us of the #1 open source myth: Open source is comprised of mostly volunteers. The truth is, these days, pretty much any major open source project has people who are paid to work on it. There are always people who do it because they love it, but these days most of us are paid (and still love it). Over the years we have learned that if you want patches in a timely manner, you need people who are paid to do it. read more

Portwell’s 3.5-inch “PEB-2773” SBC features dual- or quad-core Atom E3900 SoCs, wide-range power, industrial temperature support, and six USB 3.0 ports. Portwell’s PEB-2773 extends the 14nm-fabricated Atom E3900 (“Apollo Lake”) system-on-chips in the 3.5-inch SBC form factor. Other 3.5-inch Apollo Lake SBCs include Advantech’s MIO-5350 and PCM-9366, as well as Aaeon’s GENE-APL5 and Avalue’s ECM-APL […]

It's easy to think of containers and VMs as a binary choice -- deciding whether to use a VM or a container (not both) for your use case. In his keynote at LinuxCon Europe, Brandon Philips, CTO at CoreOS, talked about a case study for using VMs and containers together to take advantage of the strengths of both.

My Sysadmin Is a FOR/NEXT Loop. Technology always has promised to save us time by doing the things we can do more accurately and with greater efficiency.

We just released our State of Mozilla annual report for 2015. This report highlights key activities for Mozilla in 2015 and includes detailed financial documents. Mozilla is not your average company.

Ubuntu's parent company, Canonical, is strongly backing Kubernetes for cloud container management. Bu that doesn't mean it's putting all its DevOps eggs into the Kubernetes basket.

Today, I’m joining Mozilla’s Board. What attracts me to Mozilla is its people, mission and values. I’ve long admired Mozilla’s noble mission to ensure the internet is free, open and accessible to all.

E-Con’s Linux-ready “eSOMiMX6-micro” COM offers an i.MX6 SoC, optional WiFi/BT and GbE, and a 54 x 20mm footprint. Its “Meissa-I” carrier is only 80 x 40mm. In 2014, we called the E-Con Systems eSOMiMX6 computer-on-module “tiny” because it used the 70 x 45mm “?Qseven” form-factor to expand upon the i.MX6 SoC. Now E-Con has bested […]

The gcc compiler offers a seemingly never-ending list of command line options. Of course, no body uses or has expertise on all of them, but there are a select bunch that every gcc user should - if not must - know. While some of them are commonly used, others are a bit uncommon but no less useful.

Over the past six months, federation of Kubernetes clusters has moved from proof of concept to a release that is worth checking. Federation was first introduced under somewhat of a code name -- Ubernetes. And then, in Kubernetes v1.3.0, cluster federation appeared. Now, there is extensive documentation on the topic.

SiFive’s Arduino ready “HiFive1” dev kit features its 320MHz FE310, the first MCU using the open RISC-V ISA. Also, Samsung is rumored to be using RISC-V. In July, San Francisco-based startup SiFive unveiled the first system-on-chips based on the open source RISC-V processor architecture: a Linux-ready octa-core Freedom U500 and a FreeRTOS-based Freedom E300.

SUSE has become not only HPE's Linux of choice, but it's now its chief cloud developer as well. What it boils down to is SUSE will use HPE OpenStack and Cloud Foundry assets to improve SUSE OpenStack Cloud, and bring to market a new, enterprise-ready SUSE Cloud Foundry PaaS.
