Mastering Tableau in 2026 by Marleen Meier - New Release and not just for the Datafam
Thank you to Packt Publishing and Shruthi Shetty for sharing this piece with me before its release and for the continuous trust in me. I remember reviewing Marleen's latest book as if it were yesterday. Time really flies; that was in the summer of 2023, nearly three years ago! Oh, how drastically things have changed in our data visualization community and in technology globally since then. Tim Ngwena's foreword added a nice touch. While AI can enhance dashboards and create s

DataFam Day in Amsterdam @Salesforce Tower
I recently visited the new Salesforce towers in Amsterdam for the first time! They have relocated a metro station down, next to the Olympic Stadium, moving it from Amsterdam Zuidas.

My goal with each class is to enrich the master's students' understan

To be honest, I wasn’t quite sure what to expect going in. However, the experience exceeded my wildest expectations. The other two participants

Snowflake Summit Stories: A Tech and AI Pilgrimage
I shall have to begin with a personal narrative before moving on to the topic of technology and innovation, I promise. To me, Snowflake is far more than just a cloud-based data platform. It's much more. The community and the people who surround it are what make it unique. It was both a blessing and a curse for me to be highly involved in the platform adoption in my previous job. Inevitably, you only recall the good things after some time has passed. I have encountered super b
