The MaybeNull attribute enables C#8's nullable references feature to provide more useful warnings, by helping it infer information about a method output.

Here's a quick tip on how to alter the sort order of a column in Power BI!

The NotNull attribute enables C#8's nullable references feature to provide more useful warnings, by helping it infer information about a method argument.

Making your Power BI reports accessible is crucial, and one important aspect is legibility. If you're using background colours to represent certain categories, then you need any text that's used in conjunction with that background to be as clear as possible. This blog demonstrates how to dynamically select the best font colour to overlay on any chosen background colour.

I was recently invited on to Microsoft Mechanics to talk about the new on-demand SQL Serverless offering within Azure Synapse. If you have been following along with my previous blog posts you will know that we've been hard at work applying Azure Synapse against real customer workloads. In the video I take you through the service by solving a real-world IoT problem for one of our telco customers.

There is a new service in town that promises to transform the way you query the contents of your data lake. Azure Synapse Analytics comes with a new offering called SQL Serverless allowing you to query your data on-demand with no need for pre-provisioned resources.When we heard about the new service we were keen to get involved, so for the last 10 months we've been working with the SQL Serverless product group to provide feedback on the service and to help ensure it meets our customers needs. During this time we've put it through it's paces by implementing a range of real-world use cases. We were particularly interested to see how it stacked up as a replacement for Data Lake Analytics, where to date there has been no clear and easy migration path.

At endjin we solve complex problems which cover a huge range of cloud services, data science techniques and industries. The work we do is massively varied and in this there is a huge opportunity. Hear about Carmel's experience in completing her apprenticeship here at endjin, and why you should consider our apprenticeship scheme!

A few years ago, I attended a Guardian 1-day Masterclass - Introduction to Data Visualisation. What I did not know then was that it would have a profound effect on how I view design. This blog is a recap of that day and reference points to consider when designing and creating graphics for data visualisation.

Did you know that Azure Synapse has great support for .NET and #csharp? Learning new languages is often a barrier to digital transformation, being able to use existing people, skills, tools and engineering disciplines can be a massive advantage.

Have you ever needed an automated process to use alternative credentials for a subset of tasks? This post will demonstrate a technique that allows you setup multiple, concurrent authenticated sessions when using the azure-cli and switch freely between them.

Have you or are you about to invest in Azure Databricks? If so, the new Spark offering in Azure Synapse Analytics is likely to have grabbed your attention and rightly so. Why is Microsoft putting yet another Spark offering on the table and what does it mean for you?

For years we have been building modern cloud data solutions on Azure and helping our customers transform their use of data to drive outcomes. Here are 5 reasons why Azure Synapse Analytics might just be the service that we have been crying out for.

Power BI Embedded is a great tool for ISVs offering a BI product for their customers. Generally, the reports exposed to the customers are personalized to some extent - one can use the Power BI JavaScript library to interact with the reports and tweak the visuals based on the logged-in user. Another way reports differ from user to user is the underlying data that user is allowed to see. This is controlled using Row-level Security. A standard method to implement Row-level security is to pass the user's email address to the data model, and have rules filter the data model appropriately based on the data that user is permitted to see. However, sometimes it can be useful to filter the data model based on more than just a user's email address. This blog indicates how to modify an Embed Request (made by Power BI Embedded) to provide additional context on what data the embedding application would like to be returned for a user to view on a report.
