Open Hack NYC: Think Place, Not Space
Tue, 09 Mar 2010 14:20:00 -0800 -

85% of all data stored is unstructured and this amount doubles every 3 months; 80% of this data also contains a form of geo term or reference. Geocoding, assigning a longitude and latitude to a geo term will allow you to show a location on a map but it won't enable to determine any further information about a place; its neighbours, parents, children or other relationships. You don't need to geocode, you need to geoparse, using a system that knows that Paris Hilton isn't the Hilton in Paris, that London, Londra and Londres are all the same place and that knows which of the 23 places called London or the 36 places called Paris you mean. Join Gary Gale, as he shows you how to do all of this with Placemaker. (slides)

The Apache site describes Pig as ”... a platform for analyzing large data sets that consists of a high-level language for expressing data analysis programs, coupled with infrastructure for evaluating these programs. The salient property of Pig programs is that their structure is amenable to substantial parallelization, which in turns enables them to handle very large data sets.”

Yahoo! Research developed Pig to facilitate programming in Hadoop. As quoted in The Register, Doug Cutting describes Pig as “SQL for MapReduce.”

In this video, Alan Gates from Yahoo!’s Grid team describes what Pig is, why you should use it, what you can do with it, and future plans for the Pig project.

Zheng Shao and Namit Jain - Hive
Fri, 07 Aug 2009 17:59:46 -0800 -

Hive is open-source data warehouse infrastructure built on top of Hadoop, started at Facebook. In this talk, Namit Jain and Zheng Shao discuss how and why Facebook uses Hive. They present Hive's progress and roadmap and describe how the open source community can contribute to the evolution of Hive.

Hive is a system for managing and querying structured data built on top of Hadoop: it uses MapReduce for execution, HDFS for storage, and adds metadata on raw files.

Advanced data warehousing is a *huge* priority for Facebook -- in March 2008 the service was generating about 1TB per day in March 2008; in mid-2009, data production had increased to 10TB per day.

Wed, 29 Jul 2009 07:04:10 -0800 -

Open Hack Day 2008 - a hackumentary | Part 1 from ricky montalvo on Vimeo.

This episode: In part 1 of this 4-part series, Yahoo! opens its doors to developers in one of the biggest hack events ever assembled.


Synopsis: What if one of the world’s leading Internet companies opened its doors to "hackers" --allowing them access to some of its most important products and platforms to see what they could create?

That's what happened in September 2008, when over 300 developers descended on Yahoo!'s campus for an event that is every coder's dream.

This first Yahoo! short film documentary presents the intense, fun, and real-life Hack culture as illustrated by the Open Hack Day attendees. The short will show the lives of the participants as they compete in the ultimate in developer/coder showdown, discovering not only their "hack" habits and personalities, but also sharing what the developer community is all about.

Jonathan Gray & J-D Cryans - HBase Goes RealTime
Mon, 20 Jul 2009 18:51:53 -0800 -

Jonathan Gray and Jean-Daniel Cryans introduce their latest release of HBase.

Jonathan Gray is the co-founder and CTO of Streamy.com, which has been using HBase in production for about nine months. Jean-Daniel (J-D) Cryans is an HBase committer and Universite de Quebec graduate student, currently working as an Hbase consultant for OpenPlaces.com. Together they've released HBase 0.20 -- the performance release -- rewritten and re-architected for the Web.

HBase is a storage system that's built on top of HDFS. The guiding philosophy of their release: to unjava-fy everything. Some of the major changes: new key format, new file format (HFile), new query API, new result API and optimized serialization, new scanner abstractions, and new concurrent LRU block cache.

See for yourself.

Tom White - Running Hadoop in the Cloud
Sat, 11 Jul 2009 14:25:23 -0800 -

Tom White, Cloudera engineer, Hadoop committer, and author of Hadoop the Definitive Guide, from O’Reilly and Yahoo! Press, talks about running Hadoop in EC2.

He opens with a discussion of the Berkeley RAD Lab paper on cloud computing and walks us through a set of definitions to a discussion of the public cloud. He sees a realm of interesting possibilities: an apparently infinite resource; the elimination of user commitment; and the pay-as you go model, which enables elasticity. Tom describes the implementation of Hadoop in this landscape.

Yanpei Chen & Laura Keys: Energy Efficient Hadoop
Tue, 07 Jul 2009 18:39:42 -0800 -

There are compelling economic reasons to run datacenters with energy efficient software, as UC Berkeley researchers Laura Keys and Yanpei Chen describe in this talk. Typically, datacenters are measured using a Power Utilization Efficiency (PUE) metric-- but until now the role of software in the equation has been neglected.

The speakers include energy use as a dimension of software performance alongside productivity and resource consumption metrics, and describe their experiments and findings on changing Hadoop software parameters to improve energy efficiency.
