If you don't have your ticket yet for the Tableau Customer Conference in Washington D.C., you're gonna want to pick it up before Friday, when the early bird discount expires. In addition to keynotes by Nate Silver, Charles Wheelan and Tableau's co-founders, we can finally announce some of the Tableau customers who will be speaking at TCC about how they use Tableau in their own companies. Alongside household names like LinkedIn and Wells Fargo, you'll have the chance to hear from small- and medium-sized companies and agencies, including AudienceAudit, Manpower Group and the Broad Institute.

Tableau Server has many built in features to promote data exploration, collaboration, and security. The Data Server is arguably the most powerful of these tools but is commonly overlooked and underutilized.

The ability to author a calculation once and share it with everyone, creating a standardized definition for each field? • Are you tired of having to deploy database drivers on each users local machines? • Do you want to simplify how your users access data stored in your databases? If you found yourself replying 'yes' to any of these questions, then it’s time to unleash the Data Server.

Since I myself am not an familiar with JavaScript even in the slightest, I decided to sit down with someone from Tableau who is and get their perspective on how big a game changer this API really is. Fortunately for me (unfortunately for him) Michael Kovner, Tableau Product Consultant and JavaScript dabbler, sits close enough for me to harass on a near daily basis.

Today, our friends at Cloudera have formally launched their SQL-on-hadoop offering called "Impala". Did you know that Tableau was one of the first ISVs to support Impala?

Sets have been an evolving part of Tableau Desktop and that remains true in 8.0. Our New Features page offers an excellent overview of the new possibilities available to you using sets in 8.0. With this blog post, I wanted to get a little deeper into two ways that sets can help you make your data more meaningful and useful in dynamic ways: adding sets to hierarchies and using sets in calculations.

As March comes to an end, let's have a look at what people have been blogging about this month. I'd like to thank all of those who are out there, blogging about Tableau. Whether it's innovating new ways to use the software or applying it to real data, we're hugely grateful!
