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.
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-4.2# dnf 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.
The 2015 SouthEast LinuxFest (SELF) made its seventh annual appearance last week, this year filling the quiet halls of the Sheraton Charlotte Airport with the voices of the free and open source community.
This was my first time at the show, but it is most definitely a local favorite for those Red Hatters based in Raleigh. Charlotte is a city in transition, with some interesting spots to find culture and ridiculously good cuisine. The event itself had the feel of similar regional FLOSS conferences, along the lines of SCALE, Texas Linux Fest, and LinuxFest Northwest: run by a team of dedicated (and slightly exhausted) volunteers that went out of their way to make attendees and exhibitors feel welcome.
OSAS was well-represented at SELF, presenting on a variety of topics that displayed just some of our expertise.
If you wanted to attend DevConf.cz in Brno this week, but couldn’t make it there in person, you’re in luck. The event is live streaming from some of the sessions, and video archives are available on the RedHatCzech YouTube channel.
Many of us are finalizing our FOSDEM plans and preparing to head to Brussels, then we’ll have a few days to recover before DevConf.cz starts in Brno. Planning ahead for DevConf.cz, here’s a preview of some of the upstream project talks.
After Tim Burke’s keynote, The Future of Red Hat, DevConf.cz attendees will have a schedule full of great technical talks to choose from, including:
Fedora 21 officially rolled out Tuesday December 9th and made a lot of headlines. Congratulations to the Fedora community on an exciting new release that’s getting rave reviews. Word on the street is Fedora 21 was well worth the wait.

Here are a few of the articles that explain what you can expect with the latest (greatest) Fedora release:
This week, Fedora 21 (a.k.a., the release that must not be named) hit FTPs mirrors everywhere, with a feature list led by a new organizational structure for the distribution. Fedora is now organized into three separate flavors: Workstation, Server, and Cloud.
Fedora’s Cloud flavor is further divided into a "traditional" base image for deploying the distribution on your cloud of choice, and an Atomic Host image into which Fedora’s team of cloud wranglers has herded a whole series of futuristic operating system technologies.
Applications: Fedora Atomic is built to host applications in docker containers, which provide a simple-to-use means of getting at all the workload-hosting goodness that’s built into Linux, but that tends to require some assembly.
