I found this interesting Node.js article from The New Stack. A handy piece for those of you considering Node and especially now that we now have it in both Software Collections and OpenShift. "Why Node.js is an excellent and underutilized enterprise tool "Node.js, after cutting its teeth for a few years in the open source space, then being used by large-scale startups like LinkedIn and Joyent, it is now heading for the enterprise. From scaling virtualized hyper visors to operating...

Excerpts from the original article: "Now that Red Hat Enterprise Linux 7 is generally available, we are re-casting the Red Hat Enterprise Linux High Touch Beta program into a series of Red Hat Enterprise Linux 7 special interest groups (SIGs), the first of which is focused on application containers. The Red Hat Enterprise Linux Atomic Host SIG encompasses technologies that are required to create, deploy, and manage application containers. "We also announced today that Red Hat and Google are collaborating...

Excerpts from the original announcement: "Red Hat and Google are both committed to open source and we were both early proponents of Docker as well as key contributors to the Docker project. We are now joining forces to drive a new open standard around orchestrating Docker containers at scale for the management of cloud application deployments. "Today, Red Hat is announcing that as part of Project Atomic, we are collaborating with Google to tackle the challenge of how to manage...

Debugging software is something akin to an art form but, regardless of the approach you prefer, having good information on what's happening in your application is key. ltrace is one tool you may wish to add to your belt - a debugging tool that attaches to a running process, and prints to the terminal or a log file the library calls and/or system calls made by that process. In both its mode of operation and command line interface, ltrace is...

Reposted in its entirety from rhelblog.redhat.com. When Red Hat Enterprise Linux 5 was first introduced in 2007, it was done so with an expected seven year lifecycle. Five years later, in 2012, we saw the continued strong adoption of Red Hat Enterprise Linux 5 and decided to extend its seven year lifecycle to 10 years. Now, in 2014, the original retirement year for Red Hat Enterprise Linux 5, we still see an active, dedicated customer base that has come to...

As html5 and client side solutions become more prevalent, the need for handling more and more data through javascript will increase. One such challenge, and the focus of this article, is a strategy for handling hundreds of megabytes of data through Web Workers. What created this need for me personally was the development of Log Reaper [1] which is a client side approach to parsing log files with no server side upload or processing. Log Reaper identifies and parses log...

As many of you have probably heard, Red Hat announced a new " Docker server" at Summit. The new server is called "Atomic" and details can be found at the project home page. As you all know, I tend to be interested in using Software Collections to ensure the portability of applications. So, putting my foot^W money where my mouth is, I decided to download Atomic, run it as a VM, create a Docker image with a Software Collection, and...

UPDATE: Read the new article " How to run systemd in a container" for the latest information. I have been working on Docker for the last few months, mainly getting SELinux added to help CONTAIN Containers. libvirt-sandbox – virt-sandbox-service For the last couple of years I was working on a different container technology using libvirt-lxc, in addition to my regular SELinux job. I built the virt-sandbox-service tool which would carve up your host system into a bunch of service containers...

If you are anything like me, you live in perpetual fear of breaking your primary machine. The one you use for reading email, twitter, notifying you of meetings, etc. Over the years we have seen many attempts to alleviate this problem, things like etckeeper, using git to manage home ( duck it), regular backups (sure...), etc. Today, I stumbled across one of the benefits in Software Collections that I hadn't noticed before. My internal monologue went something like this: me...
