In PowerQuery you can reference a variable just by its name. But you can now also put an @ in front of the name. Is this just syntactic sugar, or does the @ add some extra functionality? #PowerQuery #PowerBI #sqlhelp

SQL Server 2025 Is Out, and Standard Goes Up to 256GB RAM, 32 Cores!
Today marks the official birthday of Microsoft SQL Server 2025. Here's where to download the evaluation version. Here are the top things you wanna consider as you talk to your managers, developers, and end users. The feature differences between 2025 Enterprise and Standard have been revealed, and the news for Standard Edition folks is spectacular: it now supports up to 32 CPU cores and 256GB RAM!

Yeah! Belgium Central is open for business. A new Azure zone at a few kilometers from the office... No more complaining about latency, I guess 😁💪 #Azure #Belgium

When I use the CopyData activity in a #MicrosoftFabric pipeline, it allows for blanks in the column names. But then I try to append to the existing table from the lakehouse explorer, I get the error that blanks are not allowed... weird 🤔

I'll get straight to the point. We trained 2 new models. Like BERT, but modern. ModernBERT. Not some hypey GenAI thing, but a proper workhorse model, for retrieval, classification, etc. Real practical stuff. It's much faster, more accurate, longer context, and more useful. 🧵
