C# 8.0's nullable references feature dramatically changes a fundamental aspect of the language. In this post, Ian explains how to you can soften the impact by enabling gradually across your projects.

Azure Key Vault safeguards encryption keys & secrets for secure data access. It offers isolated storage, AD integration, RBAC, and access policies.

This is the final blog in a series about DAX and Power BI. This post focuses on the CALCULATE function, which is a unique function in DAX. The CALCULATE function has the ability to alter filter contexts, and therefore can be used to enable extremely powerful and complex processing. This post covers some of the most common scenarios for using CALCULATE, and some of the gotchas in the way in which these different features interact!

Ensure Power BI report quality by connecting to tabular models, executing scenario-based specs, and validating data, business rules, and security.

I doubt that it's escaped anyone's notice that we have suddenly been thrown into a world which is pretty unrecognisable from that of even a few weeks ago. And I don't think any of us can claim to be managine it well all of the time, but in this post Carmel runs through some of the strategies and coping mechanisms which have helped her adjust.

Ian discusses inferred nullness and its significance in C# 8.0's new Nullable References feature.

This is the sixth blog in a series about DAX and Power BI. This post focuses on relationships and related tables. These relationships allow us to build up intricate and powerful models using a combination of sources and tables. The use of relationships in DAX powers many of the features around slicing and page filtering of reports.

Jess and Carmel recently gave a talk at Azure Oxford on Combatting illegal fishing with Machine Learning and Azure - for less than £10 / month. The recording of that talk is now available for viewing!The talk focuses on the recent work we completed with OceanMind. They run through how to construct a cloud-first architecture based on serverless and data analytics technologies and explore the important principles and challenges in designing this kind of solution. Finally, we see how the architecture we designed through this process not only provides all the benefits of the cloud (reliability, scalability, security), but because of the pay-as-you-go compute model, has a compute cost that we could barely believe!

We are currently living in extremely uncertain times. As we try to process these changes, many of us have found that we do not have the same mental capacity we once did. Some of that might be due to extra constraints on our time, but a lot of our brain-power is also spent trying to process the huge worldwide changes which are currently taking place. In this blog, Carmel talks about some techniques for managing that mental capacity, and how those apply in an ever-changing world.

C# 8.0 nullable references detect null-related errors and enhance code expressiveness.

This is the fifth blog in a series on DAX and Power BI. This post focuses on table functions. In DAX, table functions return a table which can then be used for future processing. This can be useful if, for example, you want to perform an operation over a filtered dataset. Table functions, like most functions in DAX, operate under the filter context in which they are applied.

Explore C# 8.0's nullable references feature, as Ian discusses its impact on default nullability assumptions in this informative post.

This is the fourth blog in a series about DAX and Power BI. We have so far covered filter and row contexts, and the difference between calculated columns and measures. This post focuses on aggregators. We cover the limitations of the classic aggregators, and demonstrate the power of the iterative versions. We also highlight some of the less intuitive features around how these functions interact with both filter and row contexts.

Wardley Maps are a fantastic tool to help provide situational awareness, in order to help you make better decisions. We use Wardley Maps to help our customers think about the various benefits and trade-offs that can be made when migrating to the Cloud. In this blog post, Jess Panni demonstrates how we used Wardley Maps to plan the migration of OceanMind to Microsoft Azure, and how the maps highlighted where the core value of their platform was, and how PaaS and Serverless services offered the most value for money for the organisation.

If you use Azure Functions on a regular basis, you'll likely have grappled with the challenge of testing them. Even now, several years after their introduction, the testing story for Functions is not hugely well defined. In the final post in this series, we show how to ensure specs written using Corvus.Testing can run as part of your build pipeline.

If you use Azure Functions on a regular basis, you'll likely have grappled with the challenge of testing them. Even now, several years after their introduction, the testing story for Functions is not hugely well defined. In the fourth of this series of posts, we look at how configuration can be supplied from your tests to the functions apps being tested.
