Data Driven

Frank ponders weather prediction models, the confusion matrix, and cognitive biases.

While at SQL Saturday Chicago, Andy gets recursive by talking to Andy. Seriously, he meets up with Andy Yun, one of the organizers of SQL Saturday Chicago.

Straight from the Windy City SQL Saturday, Andy chats with Cathrine Wilhelmsen to dicusss all things BIML, matching shirts, and data.

Andy’s in the Windy City on this St. Patrick’s Day attending SQL Saturday and he bumps into Bill Wolf.

In this Deep Dive, Frank and Andy delve into the depths of Data Integration and SQL Server Integration Service.

In this Data Point, Frank recounts how he has a new approach to troubleshooting WPF performance issues, or any issues for that matter.

Frank and Andy chat with Adam Hecktman, Director of Technology & Civic Innovation Chicago, about his work with data for the public good.  It was Adam who inspired Frank to get into data science.

Frank is in Reston tonight to speak at a new Meetup that focuses on AI and Machine Learning.

Frank and Andy talked about doing a Deep Dive show where they take a deep look into a particular data science technology, term, or methodology.  And now, they deliver! In this very first Deep Dive, Frank and Andy discuss the differences between Data Science and Data Engineering, where they overlap, where they differ, and why so many C-level execs can’t seem to figure out the deltas.

Yes, Andy and I are still alive and we’re doing well. 2018 has started off like gangbusters for us both. Andy is going full bore in his consulting business and I’ve been big into Big Data, between delivering five online courses on Hadoop for WintellectNOW. There is a new episode in the hopper and it will be out soon. If you’d like to learn how to make the most of Azure Government, then check out these free courses I’m delivering in the DMV area.
