Update 05/21: Microsoft shared a presentation on how to use your MSDN benefit to convert your Office 365 Developer Preview to get a year free.
"The easiest way to get started developing SharePoint apps with LightSwitch is to sign up for a free trial of an Office 365 Developer account at dev.office.com. Because Office 365 has moved from preview to release, if you signed up for a preview account, you have until May 31st to convert it to a paid subscription. Doing so will save all your content," Microsoft stated.
Check the step-by-step slideshare by Randall Isenhour from the Office content team:
Today, Hortonworks announced the general availability of Hortonworks Data Platform (HDP) for Windows.
The beta version of HDP for Windows was released two months ago at the Strata Conference in Santa Clara Hortonworks and was well received by industry press.
""Hortonworks Data Platform (HDP)", is the industry's first 100 percent Open Source Apache Hadoop-based distribution for Windows and it helps to accelerate the adoption of Hadoop in the enterprise by diversifying the number of platforms that it can run on.
With HDP for Windows customers can deploy Hadoop today on Windows Server in their own data centers.
In addition, "HDP for Windows offers easy migration to HDInsight: Customers can migrate seamlessly from HDP for Windows to Windows Azure HDInsight Service to take advantage of the elasticity and low cost of Hadoop in the cloud."
You can download HDP for Windows from Hortonworks and start testing.
