We’ve all seen the rise of natural language features in #MicrosoftFabric—Q&A, Copilot, and now #DataAgents. It’s exciting stuff, but here’s what I keep coming back to: Without a solid #SemanticModel behind it, your Data Agent won’t be half as useful.

Very annoying indeed… 🤬 and much more mouse movement as a result

Thanks #Microsoft @microsoft.com for moving the Edge browser profile switching from the top left to the top right! Why??
~5 years of muscle memory! Sigh 🤬

Validating Azure Key Vault Access Securely in Fabric Notebooks Working with sensitive data in Microsoft Fabric requires careful handling of secrets, especially when collaborating externally. In a recent customer engagement, I needed to validate access to Azure…

🔐 When working with customer environments, security is everything. Recently, I needed to confirm access to Azure Key Vault in a Microsoft Fabric Notebook—without ever revealing or printing the actual secrets.

Wrote up the process in a short blog—check it out 👇

💡 Behind the Scenes: How I Automated My Fabric Workshop 💻

In my latest blog, I share how I used PowerShell and Fabric REST APIs to:
✅ Bulk create Fabric workspaces
✅ Assign capacities and permissions
✅ Automate cleanup after the workshop

Well, that's a way to start your Monday!🙃 I've found a case in which Copilot is better than the regular feature!

I was looking for a specific email in my flooded Outlook. I asked copilot to find the mail and specifically about parking at that certain appointment. AND IT WORKED LIKE A CHARM 😲

Fantastically insightful session with fancy @jaypowerbi.bsky.social and @marclelijveld.bsky.social: A Data Analyst’s Guide to Microsoft Fabric. Power BI, Dataflows, Lakehouse, Copilot, and more—packed with practical knowledge!💚

Up next tonight are Ian Smith and Grijs Dekkers talking about Fabric architecture. Well, Grijs is here in spirit.

Jordy Sels and Maria Lysenko are preparing to present the first session this evening. Hosted by Sopra Steria.

How did you implement #security in your data estate? Are you sure it is secured end-to-end? Frequently, I come across half-baked security implementations where the front door is locked, but the back door is open.

#MicrosoftPurview #MicrosoftFabric

It is already a few days ago, the last conference of this year for me! This time a precon with my partner in crime @jaypowerbi.bsky.social. We deep dived in #PowerBI Visual Calculations!

Also, delivered a regular session on “Changing the way how we interact with data” #MicrosoftFabric #AISkills

And then you find out they extended the deadline 😅😂

That’s it! Boarding and flying back home ✈️

After an amazing week at #MSIgnite in Chicago, I added a few more days there, and four more days in New York together with the lady! We had a great time! Now time for a nap 😴

Do I see you in Oslo in February? So much looking forward to this one! Secure your tickets now!!

Full Impact Analysis in Power BI, Export and Analyze in Excel Imagine you have a semantic model in the Power BI Service (or Fabric if you will), and you’re about to make a breaking change to this semantic model. How do you inform your end users? How do …

Always great to catch up with likeminded people at conferences! #powerbinextstep @jamesdales @jaypowerbi.bsky.social

How many times have you heard "copilot" in the past 8 hours? Probably a lot, and so do I! In everyday conversations with customers and colleagues it's mentioned at least every 10 sentences.

I decided to write down my take on copilot in a blog!
