Groupon: Controlled Experimentation to Guide Product Innovation by Rajesh Parekh

Mar 262013
 

Controlled Experimentation (or A/B testing) has evolved into a powerful tool for driving product strategy and innovation. The dramatic growth in online and mobile content, media, and commerce has enabled companies to make principled data-driven decisions. Large numbers of experiments are typically run to validate hypotheses, study causation, and optimize user experience, engagement, and monetization.

The popularity of controlled experimentation has given birth to several companies that specialize in offering tools and services to effectively setup, manage, and monitor large-scale tests. While the simplicity of this concept is disarming, there are several pitfalls that can stymie progress and occasionally lead to poor decisions.

In this talk from The Hive’s Big Data Think Tank Meetup at Microsoft Rajesh Parekh discusses the guiding of product innovation with controlled experimentation:

Scalr: Setting Up Automated Scaling

Mar 132013
 

This talk is the third of four from the Dynamic Scaling meetup organized by SF Bay Area Large-Scale Production Engineering.

(from Meetup)
Despite all the buzz about it, building a horizontally scalable application for cloud deployment isn’t all that different from building one for a physical deployment, except in its ability to change size on-the-fly. Bigger applications have been using commodity hardware and fault-tolerant design to achieve high availability and scalability for a while, but provisioning capacity remains troublesome there. The real addition the cloud brings architecturally is the ability to add new resources instantly, and even change your provisioning profile algorithmically.

The talk is from Sebastian Stadil, founder of Scalr, and it’s called “Setting Up Automated Scaling.”

Hadoop: Recent News From Mahout

Mar 062013
 

Let us preface this by apologizing for poor recording quality! We had a technical issue that caused clipping on the audio. :(
We will get a transcript up soon to save your ears.

Despite that, we’ve got a recording from the Hadoop meetup last night in AppNexus. Ted Dunning, Chief Application Architect at MapR Technologies, will talk about recent developments in Mahout and real-time learning.

In particular, Ted covers the results from quality and speed testing of Mahout’s new super-fast k-means clustering algorithms (hint, quality is very good and speed is phenomenal). He also dives deep into a design for a on-line clustering facility that can cluster the full content of the Twitter fire-hose into thousands of clusters in real-time.
