This is exactly what it looks like: We're going to make you sing. ;)

The Complex Ethics of Piracy This talk aims to replace the "piracy is good" vs "piracy is theft" debate with a more nuanced understanding. It will investigate when piracy is selfish; when it is civil disobedience; whether it is ever constructive for cultural industries, or whether it is ever, as copyright holders argue, "theft". I will conclude that each of these things is sometimes true about piracy, and that simple views are inadequate for understanding the ethical dimension of copyright infringement. Both pirates and copyright industries need to develop more subtle understandings of the morality of file sharing.

The United States has a treasure trove of nautical charts in digital form, including plots of shipwrecks, navigation buoys, coastal and river depths, and other fine booty. OpenStreetMap is an open source, open format collaborative project for building a free map of the world. Join this session to find out more of the marine secrets of the National Oceanographic and Atmospheric Administration (NOAA), OpenSeaMap's plans to extend OSM to the high seas, and splicing the two (and your mainbrace) together. We'll use the Geospatial Data Abstraction Library (GDAL), OGR, Python, and the OSM API.

With millions of users signing on daily to access their favorite social media services – be it Twitter, Facebook or Digg – a developer’s worst fear is not having the backend support to house and provide access to such huge amounts of related data. Industry efforts to architect next generation databases that can scale massively by pairing open source databases and content management technologies with cloud-computing are underway. The door is also “opening” to a whole new world of user benefits which will be made possible by access to data -- cross-cloud -- in non-proprietary databases and content management systems.

RDMS showed us the one true way to organize data, yet the NoSQL movement shows us how it fails. The faithful are confused and concerned. The heretics rally boldly in the streets with torches and pitchforks, yelling something about "doesn't scale," while the defenders of orthodoxy scream about the features and safeties these strange new gods lack, and do the apostates even realize it? As the philosophical storm brews, DB admins and developers must make fateful decisions that will affect the rest of the code's life. Here they will glean the first glimpses of the knowledge they will need to make informed choices and be spared the wrath of the database gods.

What are the three highest priorities for your FLOSS project, what's blocking you, and can we help? A guided discussion.

Open source content management systems are now mainstream among non-profit organizations. See examples from live social change sites of how they're taking advantage of Plone to further their missions.

What is X? Why do we still use it after twenty years? What will we be doing with X and graphics in the future? Come have these questions, and more, answered in a straightforward, simple manner.

Battling the minions of evil is not an appropriate time for cowboy database design. Your users' lives, and perhaps those of the entire world, depend on accurate and up-to-date data. You can't take a chance on duplicated data becoming inconsistent. You need a solid data model with little or no maintenance. At the same time, a zombie apocalypse is hardly the right situation to prioritize the purity of the data model over usability. Your users need answers fast, and their brains may already be appetizers by the time a dozen joins complete. How do we prioritize both maintainability and performance? A good DB admin knows whether normalization is the right approach for a particular data set, how far to normalize, and when and how to denormalize to improve performance. Let's hope the warriors of the forces of light have a good DB admin. If they call on you, are _you_ up to the challenge?

Large-scale web projects use sophisticated staged deployment systems, but the prospect of setting these up can be daunting. Using virtualization and automated configuration puts the benefits within easy reach even for small projects. David Brewer explains how Second Story uses Linux, VMware Server, and AutomateIt to grease the wheels of development on their museum-sector projects.

The Drizzle Project is a fork of the MySQL 6.0 server.

It may seem obvious to some, but the socialist imagery that Mozilla uses isn't accidental. Nor is the grounding of Activity Streams in socialist theory. What do these things have to do with open source an its future? A lot, and I'll paint a picture to tell you how it should play out.

Preparing for the big launch

A webpage typically will be as slow as the slowest request in the page. So if for a high traffic website like Yahoo! frontpage has lots of such possibly slow external apis, it could hold webserver processes and also effect user experience. Multiple Retry is a feature meant to optimize server resource utilization and efficiently use webserver processes/threads.

If I could convince developers of one thing it would be this: Writing tests and using version control together during development is the simplest way to improve your life. So I will.

Since free software "is a matter of liberty, not price", developers and distributions are allowed to ask users to pay for free software (though most users can easily choose not to). Musicians like Radiohead have experimented with asking, but not requiring, users to pay for music (by choosing their own price, which could be $0). What would happen if we did this for free software?

perl5i is a single module bringing together the best magic Perl programmers have to offer catapulting the basic language forward. Suddenly everything is an object! Functions return objects and throw exceptions! You don't have to load six modules to work with files! Perl 5 is fun again!

The most common way of using SSL/TLS encryption relies on a public-key infrastructure that puts near-absolute trust in a large number of entities around the world, any one of which could accidentally or deliberately empower anyone to impersonate any site or service and spy on all of our communications. We've seen that these certificate authorities can make mistakes. We need new mechanisms to meaningfully double-check that they're doing the right thing.

This presentation explains how to take advantage of open source collaborative best practices to effectively work across distributed development teams.

SINNERS!! HEAR ME!! For too long have you lain contented and SLOTHFUL in the illusion that time is infinite!

Thomas Jefferson envisioned a nation of self-sufficient citizen farmers; programmers like Alan Kay and Bill Atkinson tried to help us code as easily as we might hang a poster on the wall. What happened to the HyperCard ideal? Have we settled for consumption over creation? I will explore the question through a case study, surveying the state of citizen programming in 2010 — from CouchApps to Shoes to plain-jane HTML5+JS to HyperCard 2.4 — and try to convince all comers that realizing the dream of the citizen coder is vital to continuing the ideals of open source.

Open source is a lot of the time about the code. But what about the configurations? In some cases, configuring a platform can take significant time and depending on the configuration, the resulting application can be very different and address varied uses. The power users/developers of TikiWiki CMS/Groupware had exactly this problem of configuration being too tedious and full of reinventing the wheel each time. They then figured out a way to share configurations as easy-to-learn YAML inside a wiki so that other power users/developers can make use, enhance and combine these modular application configurations, leading to new and innovative applications that are easily deployed through an automated system. The same approach should be possible for configuration sharing for many different platforms, not just Tiki.

Every time your server sends or receives a packet, it copies it to (or from) a temporary kernel buffer. What an incredible waste of CPU and memory bandwidth! RDMA solves this, at a huge complexity cost. This talk will cover what happens when a dynamic language meets a direct-memory-placement protocol.

You've worked really hard on your software. It's stable and has lots of nice features and users love it. But your sysadmin hates it and complains about how hard it is to install, configure, and manage. What's up with that?

Lots of attention has been given to GPUs for speeding up certain types of computations. While GPUs are very well suited for vector operations, there are other things they are not so well suited for. FPGAs (Field Programmable Gate Arrays) are not used as widely yet, but they offer a much more flexible computing fabric than GPUs. You can implement a GPU in an FPGA, for example, or you could implement your own custom processor optimized for very specialized tasks. The barrier to entry can be high for FPGAs: how does a person with a software development background get started using them? And what about HDLs (Hardware Description Langauges) used to program FPGAs? What's the difference between simulation and synthesis? What kinds of tools are freely available? These are some of the questions that will be addressed in this session.

Starting a business is easy. Starting a successful business is only a little bit harder. But how do you keep an open source training business going and making money when the shine has worn off and it's now just hard work?

You have so much you want to teach, how do you structure it so that your training course is both interesting and challenging? How much theory can you squeeze into an hour before your attendees have forgotten where you started? How do you structure your course to account for classes which move slower or faster than average? This talk will cover all of these answers and more.

Software development requires not only technology, but also an understanding of engineering economics and human interactions. Engineering economics is the obtaining, allocating and deploying of resources, including individuals with specific skills and temperament, to efficiently develop software that meets the needs and expectations of its users. Programming is considered a technical activity but it is first and foremost a human activity whose success is determined by emotional intelligence, innate talents, personality and communications.

You may know Java or C# ... but do you own it? Can you add new language features to suit your needs? Of course not ... but with Clojure, you can! Clojure is more than a powerful language, it's a powerful language toolkit.
