Make: Arduino Bots And Gadgets: Six Embedded Projects With Open Source Hardware And Software (Learni is an open-source project developing the industry standard solution for building and managing virtualized data centers and cloud infrastructures. The presentation will describe the unique innovative features provided by OpenNebula and its integration capabilities that allow to build a cloud within any data center environment. The target audience are integrators and IT administrators interested in deploying a private cloud solution or in the integration of OpenNebula with other projects. The talk will be useful for both people with experience or without prior knowledge of OpenNebula, as it will start by introducing the project and its main features, along with a quick demonstration. By the end of the presentation attendees will have a comprehensive idea of the integration and customization capabilities of OpenNebula.

Do you know what people are really doing in your open source project? Having good community data and metrics for your open source project is a great way to understand what works and what needs improvement over time, and metrics can also be a nice way to highlight contributions from key project members. This session will focus on tips and techniques for collecting and analyzing metrics from tools commonly used by open source projects. It's like people watching, but with data.The best thing about open source projects is that you have all of your community data in the public at your fingertips. You just need to know how to gather the data about your open source community so that you can hack it all together to get something interesting that you can really use. This session will be useful for anyone wanting to learn more about the communities they manage or participate in.

VCs try to pick winners among possible portfolio companies, but enterprise IT is increasingly tasked with figuring out the open-source projects that will gather the most momentum and emulate Linux's success. The problem, however, is that despite a range of attributes open-source projects need to succeed, the breakout successes remain "Black Swans," coming out of nowhere to dominate the industry. In this session, Matt Asay will highlight key attributes to look for in open-source projects worth bringing into the enterprise, and against the backdrop of Black Swan theory will identify ways to predict the unpredictable: the next big open-source project.

This presentation will cover the history of Enlightenment, briefly touching on early releases, describing the early years and trials undergone by the EFL community until the present, and including the work that has been done to prepare for the release. It will also describe the usefulness of a desktop which scales automatically to fit its environment and hardware, including some demonstrations of E17 running on unusual non-PC devices.The talk will be targeted mainly at developers, though a normal user will also understand many topics. Attendees can expect to learn about graphics, hardware, open source workflows, and the life of a long-lived open source community. It is important because it details the creation and release preparation of one of the most awaited pieces of software in Linux history. The presentation will also include an announcement of the actual release date for E17.

When I was a kid, the computer was my favorite toy. I would spend hours of time coding just for the fun of it. This love of computers led to a career in software development, which has been greatly rewarding! But, once anything becomes a job it is difficult to stay in love with it -- even when your job is open source.So, find a hobby? Do something else! That's great, but for me nothing has the same mental reward as a good computer project. It just sucks to constantly be at the mercy of other people's demands...My solution has been simple: retro-computing! I don't just use the computers of my youth, I make them do interesting new things! It's crazy, of course...but I love it! Maybe hearing about my experiences could be useful for you to find your way to avoid burnout? You may not want to dig-out an 8-bit micro for your next project, but maybe a robot, or an arduino, or...

Innovation, cooperation and the sharing of ideas are fundamental to the success of the free software community. As several notable lawsuits came to light throughout 2011, the free and open source software community saw aggressive use of patents to restrict choice and unfairly impair market forces. We'll see how the US patent system got to where it is in relation to software in particular and discuss what's already been tried and what's currently being done to protect free operating systems. Have you ever wondered what's at stake, how much money is changing hands, who is at risk and what can help? Defensive patent pools leverage the patents of a few to ensure protection for the group against patent trolls and other aggressors. We'll see how shared preemptive resources like Prior Art and Defensive Publications can help defend Linux, GNU and related projects.

Service providers and service users are rushing to embrace cloud offerings, many of them powered by open source software. Patent holders are not far behind them. I would like to discuss patents and how they apply to cloud computing, and how to address these issues in cloud initiatives. My presentation is important to the Linux ecosystem and this event in particular because many cloud offerings, both public and private, heavily use open source software, especially Linux, in their infrastructure.The audience includes cloud service providers, open source providers with cloud offerings, and their customers. They can expect a brief and lively overview of patent law and how it applies to cloud computing, followed by an in-depth discussion of specific issues that need to be addressed when negotiating business arrangements involving cloud offerings. No technical expertise is required.

The Qt toolkit has existed since the mid-90s and has been used for development of many desktop and embedded applications, including the entire KDE desktop and tools such as VLC. In 2011 the Qt Project was established to drive the future development of the project: a true Open Source project with an open governance model, based on the models found in mature open source communities like the Linux kernel and WebKit. The main goal of the project for 2012 is to launch Qt 5.0, the first major version of Qt in 7 years.The talk will focus on how the Qt Project's community is set up, the interactions between the community members and show how a new-comer can approach the project with their ideas and contributions. The last part of the session will show what the most important features of Qt 5 are. The presenter is a maintainer in the Qt Project and was the lead person behind its creation.

Ceph is one of the most interesting new technologies to recently emerge in the Linux storage space. Based on the RADOS object store, the Ceph stack boasts massive scalability and high availability commercial, off-the shelf hardware and free and open source software. Ceph includes a massively distributed filesystem (Ceph FS), a striped, replicated, highly available block device (RBD), S3 and Swift object storage capability through the RESTful RADOS Gateway, and a simple, well-documented native API withlanguage bindings for C, C++ and Python.This hands-on tutorial will walk you through the initial setup of a Ceph cluster, highlight its most important features and identify current shortcomings, discuss performance considerations, and identify common Ceph failure modes and recovery.Good Linux sysadmin/devops background recommended for attendees. Distributed storage knowledge is a plus.

OpenLDAP's new MDB library is a highly optimized B+tree implementation that is orders of magnitude faster and more efficient than everything else in the software world. Reads scale perfectly linearly across arbitrarily many CPUs with no bottlenecks, and data is returned with zero memcpy's. Writes are on average twenty times faster than commonly available databases such as SQLite. The entire library compiles down to only 32K of object code, allowing it to execute completely inside a typical CPU's L1 cache. Backends for OpenLDAP slapd, Cyrus SASL, Heimdal, SQLite, and OpenDKIM have already been written, with other projects in progress.The intended audience is developers writing system-level code, working in environments where absolute efficiency is required, such as mobile phones and other embedded devices, and high volume databases.

The ThingSpace IoT Development Kit with STMicroelectronics combines the hardware and software you need to get your next cellular IoT project off the ground.
