Nov. 3, 2014 The New Yorker

On Nov. 3, 2014 The New Yorker’s James Surowiecki wrote “Le Divorce” about when mergers become divergers. Hewlett-Packard is spinning off Symantec, Symantec is spinning off Veritas and eBay is spinning off PayPal. One effect is that high performing employees get more money.

Jess Row wrote a short story called “The Empties” about a woman surviving an apocalypse in Vermont.

May 25, 2011 Commonwealth Club Jack Dorsey Twitter

On Wednesday, May 25, 2011 in San Francisco at the Commonwealth Club, Jack Dorsey of Twitter and Square received the 21st Century Visionary Award. Kara Swisher of AllThingsD talked with him about his journey from learning dispatch systems in St. Louis and New York City to Silicon Valley. While Twitter has become a technological and political force, Dorsey thinks his Square device will change the way mobile electronic transactions are handled around the world. While he has support from Visa, Google and PayPal are offering solutions in the same space. I wonder if there will be an announcement about some Square deal with Apple at WWDC.

Oct. 27, 2010 SDF LinkedIn Avatara

On October 27, 2010 in Mountain View at LinkedIn, the SDForum SAM SIG hosted Chris Riccomini, Senior Data Scientist on LinkedIn’s Product Analytics team to talk about “Scalable Analytical Processing with LinkedIn’s Avatara.”

Formerly of PayPal, Riccomini worked on LinkedIn’s ”People You May Know” feature and “Who’s Viewed My Profile” product. He talked about the competing priorities between high throughput and low latency and the solution of Hadoop and Voldemort. LinkedIn needed something that would support offline aggregation, event-time aggregation and query time aggregation. It had to run through a Map/Reduce shared interface to power customer facing data products. He described a layered structure from top to bottom. On the top layer is the engine. Below that are the cube, and then the cube query. At the bottom are three elements: transform, aggregator and comparator.

The result was Avatara, a real time scalable Online Analytical Processing (OLAP) System already in production. It has features like select, count, where, group, having, order and limit. Riccomini described the architecture and implementation of its storage and aggregation layers.

One new term I heard was AvatarSQLishBuilder. Apparently, even in a NoSQL environment, the code should still have the look and structure of SQL. My advice for anyone heading into Hadoop territory is to take an experienced SQL database developer with you. Java is not enough in this Wild West show.

Another new term is Yahoo Cloud Serving Benchmark (YCSB). This is a way to compare various cloud products. I thought they were talking about yogurt. More explanation is at:

Richard Taylor was there and has written a splendid article about it at:
