As application complexity increases, observing it in action becomes harder. Traditional tools are not very useful when going across programing languages. DTrace is a revolutionary tool that allows you to observe applications in AMP stack and those written in languages like PHP, Ruby, Python, Java, C, C++ and much more. This session will teach you DTrace and demonstrate techniques of using it.

Many people view topics like Map/Reduce and queue systems as advanced concepts that require in-depth knowledge and time consuming software setup. Gearman is changing all that by making this barrier to entry as low as possible with an open source, distributed job queuing system. This session dives into advanced use cases that demonstrate the power and flexibility of distributed architectures.

This tutorial will provide an in-depth tutorial on various forms of NOSQL (NotOnlySQL) datastores (key/value, data structure store, document store and wide column stores) for working with semi- structured data. The data ranges from web logs to social and knowledge graphs to configuration data stores for cloud infrastructures and other domains.

If cloud computing is one natural conclusion of open source business models, what kind of cloud ecosystem would best support open source as a whole? Join James Urquhart, author of the "Wisdom of Clouds" blog on the CNET blog network, as he explores the technology and business models that could drive the open source opportunities of tomorrow--and a few that won't.

With an increasing number of Open Source projects demanding attention, it can be hard to attract qualified contributors. Learn how to convert your community of users into a community of developers, through training, mentoring, and community management, from a project that's been hacking its hackers since day one.

The proliferation of cloud computing is inevitable, hosted apps, software-as-as-service and now dynamic on-demand utility computing is becoming the norm. The session will be a “fire-side” chat style discussion of the types of challenges presented by IT management operations personnel and how they can manage cloud infrastructure using open source tools.

Student contributions to OSS projects have great potential to benefit both projects and students. While student involvement in OSS projects can take effort on the part of the OSS community, student contributions are well worth the effort required. This talk covers the variety of ways that students can become involved in an OSS project as well as the benefits and roadblocks to student involvement.

There comes a time in a project's life when you have to make the decision: can this code be saved? Should we fix it, or declare technical bankruptcy to cancel our technical debts and start again? In this talk I'll look at when and how to make this decision without regrets.

Efficient IT infrastructures must hold to several basic properties. Changes must be tracked. Automation must be maximized. Compliance against corporate standards must be preserved. Especially in days of limited resources, how can software help solve this problem? In this presentation, we'll show how Puppet can automate, enforce, and ensure sanity in the modern datacenter.

"Turn someone else's problems into your learning material." How do you expose your project's bugs and tasks to enthusiastic new contributors? We'll be talking about how OpenHatch's software tools and process-creating guidance make it possible to reveal a FOSS project's bug and task needs to budding contributors, students, and educators creating and running FOSS courses.

Monitoring systems to collect metrics is systems administration 101. However, systems are more complicated, there are more metrics and correlation is a must to troubleshoot problems or plan for growth. As our problem got bigger, our tools didn't get better. Reconnoiter is a large-scale monitoring and trend analysis system designed to nip these problems in the bud.

Production services need to stay up, which means that there is low tolerance for downtime in the face of instability, and perhaps even less for debugging during root-cause analysis. Gimli presents an automated process supervisor and fault analyzer that creates human readable fault traces and re-spawns a downed process. Gimli is intended to reduce time and effort during fault analysis.

Ever wanted to get a bit more out of Memcached? Wondering how to set it up for redundancy or load check your server? This talk will go over all of the latest features to libmemcached. This will include information on how to setup replication, how to build a server with libmemcached-protocol, and how to pick the best hashing algorithm.

SINNERS!! HEAR ME!!
For too long have you lain contented and SLOTHFUL in the illusion that time is infinite! SOON the UNIX EPOCH will END and numbers will OVERFLOW their confines CLEANSING all in a flood the likes we have not seen since 1901!!!
The SINS of your 32 BITS will chase your children and your children's children unless you REPENT NOW and cleanse your code of the 2038 BUG!!

Data center power usage is skyrocketing, generation is not. Large arrays of ultralight satellites will someday convert sunlight into computation and global internet communication without the economic and environmental costs of ground-based data centers. World-changing open source and open hardware technology.

This talk will be about what's happening in testing. The general argument is that we're moving away from testing units towards testing functionality through integration testing. Improved mocking libraries, scripted and emulated browsers, fixtures, and frameworks means that we can effectively test that a system works.
