Video: Improving Workbook Performance Using the Tableau Performance Checklist
Just a few days ago, I had the privilege of attending and presenting at the latest Baton Rouge TUG meeting. As an LSU alumnus (Geaux Tigers!), I was thrilled at the opportunity. It was also great to see how much the Tableau community has grown there. My presentation covered something every Tableau user seeks to […]
Moving Redis Heap Files in Tableau Server
I was plugging away at various tasks yesterday when I received a fun notification from Windows: “You have low disk space on C:” This isn’t unusual, as I have an SSD on my C: drive and have to clean it up every now again. I was surprised because I had just freed up 5-6 GB and […]
Visualizing 30 Years of Oklahoma Tornados
When you think of Oklahoma, what comes to mind? Maybe you think of cowboys, farming, Native American culture or the oil and gas industry. All of those are common answers, but there’s something associated with Oklahoma’s identity more than anything else: tornados. This weather phenomenon definitely isn’t unique to Oklahoma (just ask our neighbors), but […]
10 Questions for Tableau Educator Matthew Lutton
Matthew is relatively new to the Tableau world (with a little over two years in the Tableau sphere) and I have to admit, I didn’t know about him and didn’t meet him until the annual Tableau Conference last year in Seattle. Like a bullet, he came out of nowhere and made a mark. We do […]
Data Viz: Is an MBA Worth the Investment?
“Is an MBA worth the investment? The answer to this question is the standard MBA answer: It depends. The worth of an MBA depends on a variety of factors. Perhaps the most important of these is return on investment (ROI), which can vary greatly between MBA programs. Other key factors include a program’s ranking and how difficult it is […]
Tableau Server Security Advisory: User Impersonation

Affected versions of Tableau Server include: Tableau Server 8.1 through 8.1.20 Tableau […]
10 Questions for Tableau Maestro Michael Martin
I met Michael at the first or second Tableau Conference. It was particularly memorable meeting him because he is scary smart and his appearance is remarkably similar to Art Garfunkle. Michael specializes in creating impressive social network graphs, performing target customer analysis and integrating market segmentation with product sales data. I recently reconnected with him […]
10 Questions for Juice Analytics Founder Zach Gemignani
I’ve been aware of Juice since before my days as a consultant. Around 2007, I found Juice Analytics because they were serving-up some very useful blog posts on data visualization before it was a household word. In particular, I loved an Excel add-on they had called the Chart Chooser. Zach is the CEO, and his brother and Co-Founder […]
Extract Web Data Directly to Tableau with Our import.io Web Connector
I was excited when Tableau announced the upcoming web connector at last year’s conference. I had envisioned it getting data from web pages into Tableau as easily as when I use import.io. Just enter a URL, automatically parse the structure and return the data. It was a disappointment to learn that it wouldn’t be quite […]
10 Questions for Data Fashionista Anya A’Hearn
Somehow, I didn’t actually meet Anya in person until the conference in Washington, D.C., a few years ago. I knew of her and her work with Tableau well before then. Her personality in her blog posts is consistent with her personality in person. She is gregarious and funny — a real joy to be around. […]
