I recently attended LinuxCon Europe 2015 from 5-7 October, 2015 in Dublin, Ireland. I came with high expectations and goals and I am pleased to be able to say they were met.
The conference was combined with two other conferences (CloudOpen and Embedded Linux Conference Europe) and I expected it to be a painful to navigate a huge venue, where I wouldn't be able to find anyone. Instead, at about 1500-2000 people, the combined conference was very addressable, allowed for easy crossing of tracks, and presented a fantastic "hallway track." The organizers, sponsors, and venue did a fantastic job.
Rather than recap every talk I attended, I'll talk about the event from the perspective of a software engineer working with container-related technologies. In my $dayjob I focus on Project Atomic, a collection of container-related technologies that make containers easier to implement and deploy. While the project focuses on Docker containers and tends to use the Kubernetes orchestrator, Atomic is really container-technology agnostic.

The genesis of this article was a financial industry luncheon in New York City a couple of years back at which I was invited to speak. The topic was this new "containers" thing: what it was, where it was going, and how it could best be used. Of particular interest was how containers related to virtual machines (VMs).
At this point, it's worth remembering the context in which server virtualization and its VMs became such a popular technology, fundamentally changing how many datacenters were operated and spawning a mini-industry of complementary vendors and products. Although initially introduced as primarily a tool for developers, virtualization rapidly became instead a way to carve out multiple virtual servers from a single physical server. This server consolidation was initially driven by cost-cutting, a popular pasttime after the dot-com bubble popped.

September 19 is a significant day for those of us who work and play in the world of free and open source software (FLOSS). Software Freedom Day, a global celebration of FLOSS falls on this date, with this year being even more significant, because this month also marks the 30th anniversary of GNU!
It is, at a certain level, pretty amazing: the choice to share software and see it built freely for its own sake has influenced innovation within IT for three decades. Technologies like cloud computing, big data, containers… these all were successful not in spite of FLOSS, but because of it. Free software has has a personal effect on its practitioners as well.
To celebrate Software Freedom Day, we put out the request here at Red Hat: what was your first experience with free software? The answers were full of tech, but also touched on a lot of positive emotions. Free software, lest we forget, means something, as the answers to our question certainly suggest.

One of the really great things about working with communities is when you wake up one morning and find someone has generously donated their time and effort to deliver something that benefits all.
In this case, oVirt has Wesley Morais de Oliveira to thank for releasing a set of 10 videos detailing the basic steps for setting up and configuring oVirt. This includes the oVirt Engine as well as oVirt Node.

Did you miss the Flock to Fedora conference, or just want to relive the greatness?
With many workshops, presentations, and over 200 attendees, it's safe to say that Flock 2015 was a huge success.
This year's location at the Rochester Institute of Technology was quite the compatible fit. Fedora is quite popular among RIT students and faculty alike. One RIT researcher, Jon Schull, even started the eNABLE Community Foundation a nonprofit organization that creates prosthetic upper-limb devices for children in need. These limbs are created with a 3D printer as well as open source software running on the Fedora platform. Flock attendees had the opportunity to learn more about eNABLE from Schull himself.

Borrowing from the developerblog entry, here's an introduction the fedora-tools” image for Fedora Atomic Host.
When Red Hat’s performance team first started experimenting with Atomic, it became clear that our needs for low-level debug capabilities were at odds with the stated goal of Atomic to maintain a very small footprint. If you consider your current production environment, most standard-builds do not include full debug capabilities, so this is nothing new. What is new, is that on RHEL you could easily install any debug/tracing/analysis utility, but on Atomic:
bash: dnf: command not found
Whoops! What’s this now??? If you haven’t played with Fedora Atomic yet, keep the first rule of Atomic in mind:
You don’t install software on Atomic. You build containers on RHEL, CentOS, or Fedora, then run them on Atomic… sysadmin tools are no exception.
We always knew we needed an equivalent for Fedora… and we're happy to announce today the availability of the fedora-tools image.

Pretty much going to go out on limb here and make the call: if you didn't find something that interested you at this year's pantheon of LinuxCon North America events, then you may want to start using Windows. Except Microsoft was there too, so you're out of luck. And Apple, so just settle down.
The list or speakers and sponsors was varied, to be sure, no less so than the visitor roll call. But the real variety was marked by the sheer number of events the Linux Foundation hosted in the Seattle Sheraton during the week of August 16.
