Open Source Bridge

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.

Touchscreen is a platform for creating interactive kiosk and dashboard displays. It powers presentations for visitors to the Open Source Lab's data center and the network operations center. Come learn how touchscreen works and how to use it for your own display screens.

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.

Creating a redundant yet scalable virtualization environment is often difficult and expensive. Ganeti is an open source project which offers many solutions to simplify a clustered virtual machine environment while enabling you to use low cost hardware. This session will walk through Ganeti covering its basic design goals/features, installation architecture, and production implementation.

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.

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

MongoDB is an open source, high-performance, schema-free, document-oriented database that is rapidly gaining in popularity among web developers. In this talk we'll introduce MongoDB and the features that make it great choice for your web 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.

You've launched your new web site and it's starting to get some attention. You've tuned your database and optimized your HTTP daemon, but what if it's not enough to keep up with all the hits you're getting? We'd like to introduce you to your two new best friends: Varnish and Pressflow.

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.

A follow-on to last year's highly popular presentation, Hal Pomeranz returns with another super-size helping of command-line madness!

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.

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?
