Open Source Bridge

A general discussion of NoSQL databases, what they're good for and where they fit in the database world.

Join your fellow Rubyists to talk about fun things you're working on.

PSAS is a student aerospace engineering project at Portland State University. We're building ultra-low-cost, open hardware and open source rockets that feature perhaps the most sophisticated amateur rocket avionics systems out there today.

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.

Cassandra is an open source, highly scalable distributed database that brings together Dynamo's fully distributed design and Bigtable's ColumnFamily-based data model. In this talk we'll discuss the strategies Cassandra employs to provide an eventually consistent data model.

This presentation will show how to connect to REST-based web services from an Android application. We'll discuss HTTP programming as well as XML and JSON libraries. This presentation will include a live demo of an Android application.

"This compression algorithm is of course very inefficient, at least when applied to a small collection of documents. But if you were to apply it to a larger collection, say, all the music ever recorded and all movies ever made, some gains may be realized...

Learn to hack Evently jQuery CouchApps -- p2p web applications that can be deployed anywhere there's a CouchDB.

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.

How does free software help defend free speech in repressive regimes? Danny O'Brien will draw from the records of the Committee to Protect Journalists to explore how open source can help those at the cutting edge of free expression.

Why do so many technical presentations suck? Make sure that yours doesn't. Josh Berkus and Ian Dees will show you how to share your ideas with your audience by speaking effectively and (when the situation warrants it) showing your code.

Dropbox, the leader in online storage and synchronization, is good, but not good enough. Find out how you can hack together your own equivalent that's more flexible, secure and convenient.

During this talk, we will survey real-world implementations of JIT-compiled embedded DSLs and their applications.

What is possible when you can consume servers on various hosting providers with nothing more than a python script? This talk will discuss libcloud, an Apache Incubator project dedicated to building standard interfaces into the cloud.

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.

Best practices for employers, employees and open source projects to coexist without legal conflicts.

Node.js is one of the most exciting things to happen to server-side development in the last few years. Here you'll find out why Node.js is a perfect fit for your next project and a better fit than existing languages for modern web development.

Augmented Reality and Geolocation have been hot topics this year, but there has often been a confusion between aesthetics vs. practicality, and fantasy vs. reality. This presentation will highlight the advantages and disadvantages of visual and non-visual augmented reality. We'll tell stories from our experiences building location-aware social networks with custom proximity notification.

User groups are a vital part of the open source community. Learn more about how to start a group, keep it going, and make an existing group better from a panel of experienced user group organizers.

JavaScript is a unique and powerful language. Its ubiquity in the browser and its elegant concurrency model make JavaScript an ideal tool in a number of situations. Learn about the best ways to use and to understand this language from a full-time JavaScript professional.

Serialist (http://serialist.net/) provides a way to find, track and read serialized content (e.g., web comics). It's implemented entirely in Haskell and demonstrates functional web application development, crawling, scraping and distributed architecture. Serialist uses interesting graph algorithms to add and step through content lazily.

What you need to know before you even think about raising venture or angel capital, presented by a Silicon Valley founder who raised $9m from top tier firms.

Leigh will be discussing hacker spaces, and the culture of DIY spaces for making things around the world.

Even at pro-FLOSS businesses, logistical obstacles and incentive problems get in the way of giving back. I'll show you how to fix that.

Markus: Nautilus? I thought you said noodle house! Matt: Wait, wait, I think I see her head!! Markus: Are you sure? Matt: Maybe It's Not Her Head...
