Power BI October 2026: what changed and what it means for new analysts

 Microsoft's October 2026 Power BI update adds several features that matter for people learning data analytics.

Copilot and AI. Copilot can now help build Power BI reports with custom visuals. Beginners should use it to draft a page, then check every chart against the data, because an AI-suggested visual is only as good as the fields it uses.

Reporting features now generally available:

Chart plot area background colour, for clearer charts

Auto-expanding hierarchy axis with field parameters, for drill-down reports

Personal bookmarks that keep column widths, so saved views look the same


Features in preview: a Gantt chart for project timelines, and a list slicer with a dropdown. Preview features can change before release, so check their status before using them in client work.

Semantic models also gained more accurate surge protection.

If you are learning Power BI, practise these features on a sample dataset first, and always check the numbers before you share a report.

Using Copilot in Power BI as a beginner: a checklist

 Copilot can save time when you build a first dashboard, but it does not replace understanding the data. Before you accept a suggested visual, check: 1. Which table and fields the visual uses 2. Whether the total matches a number you can check by hand 3. Whether the chart type suits the question 4. Whether the filter is applied to the page or the whole report Build the same report once without Copilot. That is how you learn what Copilot is doing, and it is the skill employers test in interviews.

10 Spring Boot Interview Questions Every Java Fresher Should Prepare

Most Java full stack interviews for freshers in Bangalore spend a good part of the time on Spring Boot. You do not need to know everything, but you should be able to explain these ten topics in your own words, ideally with an example from a project you built. 1. What is Spring Boot, and why use it? Spring Boot sits on top of the Spring framework and removes most of the setup work. Auto-configuration, starter dependencies and an embedded server let you run a web app with very little code. 2. What does @SpringBootApplication do? It combines @Configuration, @EnableAutoConfiguration and @ComponentScan, so one annotation marks the main class and starts scanning for your components. 3. Dependency injection Instead of creating objects with new , Spring creates them (beans) and passes them where they are needed. Constructor injection is the recommended style because it makes classes easy to test. 4. @Controller vs @RestController @RestController returns data (usually JSON) directly. @Contr...
