Fedora Flock Recap: Day 2

Ed. Note: The Virtio talk had the wrong description and the Game Art talk had inadvertently gotten removed from the post. I’ve fixed these things up again – thanks to gurdonark for pointing these mistakes out!

Here’s today’s Flock recap!
Oh, but wait! I have some things to tell you!

Missing Friday Videos – Miracle Appearance!

One of the saved videos from Friday was a ~2 hour long stream that had 2 talks in it and was inaccessible yesterday. Today, I was able to edit it down into the two talks. Also, another Friday talk video mysteriously appeared. So… we’ll do a “Friday: The Missing Videos” recap at the end of this post. (And there will probably be a “Saturday: the missing videos” recap tomorrow, because I see that YouTube is still contemplating some of the longer recordings from today, from ECTR109.)

Okay… Now Where Are the Auditorium Videos plz?

Well… they are on an sdcard in the camera. So they aren’t up online yet. As I understand it, some may have not recorded properly (the battery died at least once, during Robyn’s keynote, and the stream was down this morning for the beginning of the badges talk before Spot fixed it.) So… patience, my friends.

Oh, Have I Got Ideas for Making This Better Next Year…!

Why, of course you do! Some of us (so far, Ian Weller, gnokii, and I) have some ideas too. So we put together an etherpad brainstorm for Flock 2014 ideas to make it a better conference. I’d especially like to see other remotees like myself contributing to this brainstorm, because I would like to see Flock 2014 be an even better experience for remote attendees than this year. (But don’t get me wrong, this has been the best remotee access Fedora conference so far, I’m pretty sure!)

Okay hon, get to the recap!

Alrighty then!

Saturday

Lulzbot Keynote

The 3D printing community is the largest and fastest growing part of
the Libre Hardware community. With this rapid expansion, the need for
better tooling is becoming evident, both to improve accessibility to
every day users and to empower new contributors. Fedora is the first
and only major GNU/Linux distrobution to package most of the Free
Software tooling used in 3D printing today, which is an important
step, but the tools themselves need to be improved further.
This talk discusses the current state of Free Software in the context
of libre hardware 3D printing – new developments, opportunities for
further involvement, and areas of concern. The talk will also include
a demonstration of hardware from Lulzbot – the makers of the only 3D
printers that carry the FSF’s “Respects Your Freedom” certification.

KVM and Virtio Introduction

KVM ( Kernel-based Virtual Machine) is a virtualization solution for Linux. It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module. Using KVM, we can run multiple virtual machines having Linux or Windows images.
KVM uses QEMU(“Quick EMUlator”) which is a free and open-source software that performs hardware virtualization. Virtio is a virtualization standard for network and disk device drivers where just the guest’s device driver “knows” it is running in a virtual environment, and cooperates with the hypervisor. This session would be useful for those who want to understand virtualization with KVM and interested to know about how KVM, QEMU & Virtio works together.
The session will also cover few of the details about the work flow of virtio and QEMU.”

An Architecture for a More Agile Fedora

Fedora is awesome, great tech, great people, high standards, and the best enthusiast distro. But it’s also difficult to use as a base for building on, and that’s where the excitement is now and in the future. This talk presents a proposal for refocusing the core Fedora distribution as a platform, while including layers of modular enabling tech within a broader Fedora umbrella, with greater autonomy for SIGs in their own areas. This will make Fedora a stronger base for remixes and spins, an easier target for developers, enable upstream communities to work in Fedora while retaining their own conventions and culture, provide a better app UX for end users, and will put Fedora in the center of interest in computing today.

Task Automation in Fedora QA

When we talk about automation in Fedora QA, the general assumption is that we’re talking about the usual kinds of test automation. While that is what we have been doing, that’s not exactly where we’re going. Instead of focusing on more traditional test automation, our vision is to have a more generic automation system that can be used for testing in addition to other initiatives requiring a base execution system. Learn about the new push for task automation, what this means, what you’ll be able to do with task automation and how you can help.

SELinux for Mere Mortals

While Security-Enhanced Linux (SELinux) is an incredibly powerful tool for securing Linux servers, it has a reputation for being difficult to configure. As a result, many system administrators simply turn it off. Fortunately, the incredible amount of work completed by the SELinux community in recent years has made SELinux system administrator-friendly.
In this session, attendees will:

• Learn the basics of SELinux
• Review the SELinux architecture
• Discover how to configure, analyze, and correct SELinux errors
• See how to generate basic policy modules to enable non-SELinux-aware applications to work on SELinux-protected systems
• See real-world examples of how to use this tool

Btrfs – Cool Butter

Note: The video on this one was interrupted twice. I stitched the three resulting videos together into one, but there are holes where the G+ recorder disintegrates the video into soup… maybe because of the conference network? Anyway, it’s the best we’ve got! Most of the talk is understandable.
Interested in btrfs? This talk will cover how to slather yourself in this way-cool filesystem, different features that are available, and maybe the buttery future.

Scale or Fail – Give your app the Speed it Needs in the Cloud

Whether you have one or a million visitors accessing your web app, they are all going to demand a great user experience regardless of what it takes for you to deliver it. This invariably means quick page loads and fast response times every single time. In this talk we will show how core Linux tools have been used in OpenShift to deliver a kick-ass autoscaling platform. We will take a spatial web/mapping service and hit it with load and watch OpenShift just start adding new “servers” to handle the load. No proprietary solutions needed – it’s all right there in Fedora 19 and you will love to see this in action.

The Hotrodder’s Guide to Maximum Performance LAMP

Hotrods, aka drag racers, are the automotive epitome of the pursuit of maximum performance. Even though they are amazing machines, the basic concepts of how to get there are simple: reduce weight, simplify, streamline, and add power. The same concepts can be applied to server infrastructure to take your overloaded server and reduce its load to a respectable quarter mile time. Even in an age of abundant CPU power and cloud computing, the art of tuning servers for maximum performance is still relevant and pays immense dividends down the road no matter what size your IT infrastructure is. In this presentation I will cover all parts of the LAMP stack, how to tune those parts, dos and don’ts and trade offs.

Is “Cloud” Something Beyond a Buzzword and Should Fedora Care?

“Cloud” is one of the biggest tech buzzwords ever, like sticking dot-com on an idea a decade ago. It’s slapped on anything and everything these days, sometimes with very little sense. But, there is something real underneath all that. This introductory talk covers what the cloud really is and what it isn’t, with a focus on work currently going on in Fedora and on what it means for our future.
