Writeback Options in Power BI

Jon Vöge comes continues looking at Power BI writeback:

This blog has previously covered the basics of native Microsoft Fabric / Power BI write-back with Translytical Task Flows.

In my first post on the subject, we created a simple Comment/Annotation solution, allowing the user to input free text comments on Data Points directly in Power BI.

However, Translytical Task Flows do not only support Free Text as an input type for the users of your reports. All of the new & updated Power BI Slicer visuals work with Translytical Task Flows, and we can use List and Button slicers for users to add categorical data to our task flows too.

Read on to see these other options in action.

Read on to gain an overview of what options are available on the PostgreSQL side and how they differ from what’s available in Oracle.

PBKDF2 in SQL Server 2025

Vlad Drumea has my interest:

I’ve written previously about auditing or cracking SQL Server login passwords either online (inside the instance itself) or offline (exporting the hashes and using a specialized cracking tool).

Last week, Microsoft’s Pieter Vanhove published a blog post that covers What’s new in SQL Server 2025 security.

This is one of the few instances in which I’d prefer things be slower in the database.
