Big (MOOC) Data | ###b | Scoop.it

"By now it seems clear that MOOCs can generate vast quantities of data, from course completion rates, to assessments, to student experiences. Duke University recently shared comprehensive data about its first MOOC, Bioelectricity: A Quantitative Approach.  This was one of the five courses deemed worthy of undergraduate credit by the ACE, announced earlier this month."

Incredible.  Google will 'require' all advertisers to target mobile devices, even if they dont want to.... What???   I recently commented on another Internet Marketing article that quoted Frank Zappa correctly but not in a particulalry good context,  however I feel the following lyric is apt and rather fitting in this case.  'And you shall do as you are told, until the rights to you are sold'  (extract taken from 'Im the Slime' from the Apostrophe' album).

EMC to Hadoop competition: "See ya, wouldn't wanna be ya." | GigaOM Tech News

EMC to Hadoop competition: "See ya, wouldn't wanna be ya." | GigaOM Tech News | ###b | Scoop.it

If, like many industry watchers, you’ve been confused about EMC Greenplum’s Hadoop strategy over the past couple years, Scott Yara has a message for you: “We’re all in on Hadoop, period.”

 

Yara, Greenplum’s co-founder and senior vice president of products, has a not-so-coded message for his big data market competitors, too. Put simply, he doesn’t think they stand a chance against his company, and he served notice on Monday morning with the unveiling of the company’s new Pivotal HD Hadoop distribution and Project Hawq in a staged event at San Francisco’s Dogpatch Studios.

 

Pivotal HD is a completely re-architected Hadoop distribution that has been natively fused with Greenplum’s analytic database (that’s the Project Hawq part), but Yara thinks it’s a bigger deal than just another SQL-on-Hadoop play. In an interview last week, Yara told me that Project Hawq is the manifestation of Greenplum’s decision to sell itself to EMC in 2010, a move he thought would would kickstart his company’s founding vision of becoming the leading big data platform.
