This hands-on session will introduce the audience to building applications with MongoDB - the open source document-oriented NoSQL database. The tutorial will take the user through building a simple location-based (like foursquare) from start to finish. Attendees will finish the session with a working application they use to check into locations around Portland from any HTML5 enabled phone! Read more.

Open source software was one of the earliest successful examples of a sharing economy that has had huge economic impact. But as alternative energy advocate Steve Baer once noted, ecosystem services are often ignored in economic analysis: when you put your clothes in the dryer the energy you use is measured and counted, but when you hang them on the line, they disappear from the measured economy.

The Apache Hadoop project is becoming the de-facto big-data platform. The community is gearing up the first major release of Hadoop in over 2 years. This talk will cover the major highlights of the release and also the mechanics of what it takes to deliver a major Hadoop release. Arun C Murthy is VP, Apache Hadoop at ASF and the Release Manager for this release. Read more.

In this session, Ricardo Signes (rjbs), the Perl 5 project lead, will discuss the future of the Perl language, the guiding principles of its ongoing design, and the specific changes toward which the Perl 5 Porters are working. It will also describe the way Perl 5 development really happens, how that is changing, and what we might want it to become. Read more.

A look at the state of PHP in 2012 and how it fits into the current technology stack. The session will cover common mistakes and a detailed review of new PHP 5.4 features. Read more.

An introduction to high availability for the OpenStack cloud stack, using the Pacemaker cluster management framework. Read more.

Applications are only as reliable as the database they use. At Stripe, we've developed a set of practical techniques for running MongoDB without downtime even in the face of catastophic machine failure. This session will cover a range of these techniques (and the tales behind their development). Read more.

With its latest release (2.4.0), Apache httpd is ideally suited for the cloud, both in performance and capability. See what enhancements have been made so that you can also take advantage of Apache 2.4.0. Read more.

The process of writing, editing, and publishing an O'Reilly programming book has been tending increasingly into the open source domain, relying on open source tools and technologies. This talk describes one author's experience, along with considerations about the possible future of the book in an increasingly open source world. Read more.

It is common to use multiple systems as part of the infrastructure of an application, but it’s sometimes unclear to developers when to use MongoDB alongside a relational database and what the best practices are. This presentation will introduce MongoDB, make the case for hybrid applications, and outline several real-world examples of such applications. Read more.

The hacker community has enthusiastically embraced the Arduino microcontroller. Linux and Open Source hackers are some of the most sophisticated and forward thinking in the business. This talk with give them plenty of ideas for building highly capable, remote sensor projects. Read more.

This presentation will focus on a process for taking open data sources, turning them into beautiful custom maps, using them on mobile in an offline-capable way, and doing it all with entirely open source code. Read more.

Ricardo Signes (rjbs), the Perl 5 project lead, will tell you about all the changes in Perl 5.10 through 5.16 that will affect your daily life, with a focus on things you should and shouldn't use. Read more.

Illustrated guide to how to write non-blocking code for Perl (and some Javascript). Goal for this session is to give some familiarity to high-level non-blocking APIs for engineers who want to dig into non-blocking programming. Read more.

Message Queues are a hot topic, but not all are created equal. After reviewing most of the popular choices, I will review my findings and offer suggestions for which to use when, and pros and cons of each. On the list are RabbitMQ, Kafka, Apache Qpid, Kestrel, ZeroMQ and more as time permits. Read more.

Whether you use Chef, Puppet, or just basic shell scripting, there seems to be no clear way to incrementally develop and test scripts to provision a system. In this talk I'll introduce using local virtual machines managed by Vagrant as a way to achieve this, shortening the feedback loop and increasing productivity and confidence of configuration management script development. Read more.

MySQL's configuration file is often the focus of too much attention, and too much tweaking of variables that make no difference -- or worse, have the potential to negatively impact performance. The sample default configuration files that come with MySQL are unfortunately not very helpful or good, either. We'll looking in creating a better one in this session. Read more.

This talk will talk about how to optimize available hardware resources using a real-world VPS server running a full LAMP stack, including common tuning choke points and misconfigurations. Read more.

If you're one of the 50% of developers who uses vi/Vim on a regular basis, but you still only use the 5% of the editor features that you learned in school, this talk will offer you a dozen ways to instantly make your editing more efficient and productive. Read more.
