LinuxCon+CloudOpen North America 2014

Chicago is a unique venue in that it is also the place of the most valued financial market the Chicago Mercantile Exchange (CME) as well as a diverse technology infrastructure of Banks, Investment and trading companies. Linux is key to the business here in Chicago and this talk will talk a bit about the history of Linux use for trading and then give some insight into how Linux is used in trading here.

The CME is widely seen to be the leading indicator for other electronic markets worldwide and what happens in Chicago affects the rest of the world.

MySQL is the most popular database on the web but how do you grow from one instance on a single LAMP box to meets needs of high availability, big data, and/or 'drinking from the fire hose' without losing your sanity. This presentation covers best practices such as DRBD, read/write splitting, clustering, the new Fabric tool, and feeding Hadoop. 80% of Hadoop sites are fed from MySQL instances and it can be frustrating without guidance. MySQL's Fabric will manage sharding and provide more flexibility for your data. And using the memcached protocol to access data as a key/value pair can be up to 9 time faster than SQL (but you can still access the data concurrently with SQL). So do not get stuck without a plan for growth.

From research to production: over almost a decade of development, Ceph has expanded its mission, built a user and developer community, and adapted to an evolving world of storage technologies.Today, Ceph is attracting more user and developers than ever before.In this talk, we will discuss what’s new in the project, including:
•Erasure coding to reduce storage efficiency
•Tiered storage pools
•Object storage federation across multiple sites

Along with what’s new, we will also discuss how the project and its technology will adapt to the challenges of the future with updates to CephFS and emerging storage backends.

OpenStack governs itself in ever widening circles starting with the individual patch and encompassing standards for inclusion in our gate testing. OpenStack Programs self-govern when contributors review individual patches, providing the foundation for community involvement and responsibility. Leaders within programs self-nominate and participate in elections if they wish to play an official role as Program Technical Lead. Leaders anywhere in the community can self-nominate to participate in elections to be a member of our Technical Committee. Learn the mechnisms that govern the elegibilty of the electorate and candidates as well as the meaning of the responsiblities they accept.

Storage is hard. One of the aspects of that is getting files synchronized to different places, how do you do it efficiently and effectively. It's a hard problem because of the myriad of use cases from mirror infrastructures, content distribution networks, backups, remote office locations, mobile devices, websites and clouds. With a myriad of different use cases there's a huge breadth of potential options to dealing with trying to keep files in sync. I intend to do a reasonable dive into what technologies are out there for the more general use cases, get into why you may or may not want to use them, what their strengths and weaknesses are and attempt to help give guidance to folks trying to find their way through this complex and hard problem

Working with software means working with bugs. Bugs in software, bugs in hardware; bugs in Open Source code, bugs in proprietary code. If software is eating the world, bugs might end up taking the first bite.

We will present a few typical bugs, some of them famous, some of them infamous (including bugs that actually killed people). Since one can never be too well-prepared to fend off the next infestation, we will give tools, tips, and best practices to fix bugs in Open Source software. We will give real world examples of Really Mysterious Bugs (sometimes nicknamed "Heisenbugs" because they tend to disappear when you try to observe them), and how they were fixed, in Node.js, Docker, and the Linux Kernel.

To be effective technologists, we often have to tell stories and share information; either showing our technical peers techniques and approaches, or distilling information into a non-technical form for other decision-makers. Python provides a rich set of tools not just for building software, but for analysis and visualization of data. IPython Notebook gives a framework to explore, then repeatably combine explanatory text, diagrams, command line invocations, and code into a single (revision-control capable) document which can be shared as PDF, HTML, Reveal.js presentation, a blog post, or an interactive notebook file.

This talk will provide a basic introduction to working with IPython Notebook, then show several examples of effective use to meet these needs.

Finally, testing, automation, and sharing beautiful, publication (and management) ready results will be discussed.

You there, Linux administration god -- did they mention you also have a small to huge gaggle of MySQL instances that you need to take care of when you were hired? Well databases are the wanton, needy brats of the software world and will provide you quite the wild ride if you are not prepared. This session covers what every Linux admin needs to know to keep their databases happy, friendly, and efficient. Do you know if SSD really work? Where do you spend you upgrade budget for the best results? What replication strategies take the load off your main server, feed Hadoop clusters, or provide 'save your butt' redundancy? What tools do you need to ease user admin, backups, query tuning, and generally make your life easier? All this and more in a fast paced session you need to attend.

Data is emerging as the world’s newest resource for competitive advantage. As the value of insight from data continues to grow, companies are struggling with their current systems to keep pace as their present IT infrastructure and IT budget can't keep up with the increased demand for insights and volume of data. In this session we will explore why top performing organizations confront this reality by taking a different approach. Hear how companies are winning with new innovation and design that puts data to work faster with their Linux solutions. These systems are easy to consume and manage with open-source technologies, simplified virtualization management and flexible capabilities, to provide companies with a competitive advantage.

The 3D printer is changing the world as we know it, as the price for digital fabrication technology is dropping, the footprint is shrinking, and the universe of digital models is growing. Open source hardware is playing a major role in this, and Linux support is a key part of enabling this ecosystem. In this presentation, Tom will talk about how 3D printing works, why open source hardware matters, and how to go from an idea to a physical object with Linux and FOSS software.
