Internet traffic spikes aren't what they used to be. It is now evident that even the smallest sites can suffer the attention of the global audience. This presentation dives into techniques to avoid collapse under dire circumstances. Looking at some real traffic spikes, we'll pinpoint what part of the architecture is crumbling under the load; then, walk though stop-gaps and complete solutions.
Scaling is a perennial problem. One day you are happily serving 10,000 users and suddenly that pesky CNN picks you on you and you have to deal with a million users. It isn't all about putting the latest hardware, more disk or more RAM. Scaling is a subtle art of discovering pain points in the application and using various Open Source software and technologies to get you to where you want.

These days, there are countless number of software applications and web services that have been developed using free and open source software (FOSS). Such tools have become so flexible, powerful, and universal, that it should also be possible for authors to write manuscripts using FOSS in the same way that applications are developed. In this talk, we present some case studies of this phenomenon.

Chris DiBona (Google, Inc.)
Google crawls more than just web pages, we also crawl source code. Ever wondered just how much open source code is out there? What licenses is all that code under? Which projects are the most shared? We'll try to answer these questions in this talk.
Alex Martelli (Google)
Abstraction is a powerful servant, but a dangerous master. We code, design, think, debug ... on a tower of abstractions. Spolsky's Law tells us that "All abstractions leak". This talk explores why they leak, why that's often a problem, what to do about it; I also cover why sometimes abstractions SHOULD "leak", and how best to produce and consume abstraction layers.
