Notes and articles on data, Power BI, DAX, and building reporting you can trust.
Following up on my custom drop–down visual, you can now type questions in plain English and get accurate answers from your Power BI dataset, all without expensive Fabric capacity or sacrificing data privacy.
Read →Stop patching Power BI reports with endless DAX and custom workarounds. A well-designed semantic model puts business logic where it belongs and makes BI more reliable, consistent, and easier to scale.
Read →The second edition of Mastering DAX in Power BI is coming soon. Alongside practical solutions for real data problems, the updated book explores how to utilise artificial intelligence to elevate your analytics.
Read →The 80/20 rule shows that a small slice of your data usually drives most of the results. Here is what the Pareto principle means and how I built a working Pareto analysis in Power BI with four custom DAX measures.
Read →A while back, a few loud voices in tech declared that SaaS was dead. The idea was simple. AI would replace the application layer sitting on top of your data, an…
Read →Software engineering fundamentals were forged through decades of failure. Here's why leaning on AI to think for you - "thinkslope" - quietly erodes them.
Read →There are three types of companies in the AI industry right now. The ones building the models. The big platforms selling access to them. And a third group that …
Read →Europe has world class industrial data, decades of domain expertise, and the regulatory framework to build AI that nobody can switch off. The question was never whether to build a flagship model. It was whether anyone would notice there was a smarter option all along.
Read →Power BI's built-in Q&A answers with charts. For most questions, that's the wrong shape of answer. So I built a custom visual that replies in plain text — and handles the data properly underneath.
Read →The first version proved the idea. The second packs the entire AI narrative engine into one self-contained Power BI visual, so the explanation travels wherever the report goes, even to users without a licence.
Read →Microsoft's Smart Narrative needs an expensive Fabric licence and still reads like an automated caption. So I built an AI narrative engine inside Power BI that explains the data in real time, for a fraction of the cost.
