Dumb. Just dumb.
No no no begs every archivist. You are never going to be able to find anything. Please don’t start using emojis in file names. Who asked for this? What fresh hell is next?

This week we are challenging ourselves to build an actual scale chart of the average sea level changes from 1900 to 2020.

You can also extend the challenge by building in some animations.

Check out my DAX user-defined functions, which lists selected items as a concatenated string.

There, you will also find a link to a PBIX file demonstrating the different variations and use cases of this set of functions.

Pretty dang good little AMA if I do say so myself. Thanks to the #PowerBI community for filling up the queue and shout out @alper.datav.is and @jaypowerbi.bsky.social (here on Bluesky) for helping out.

Follow them and stay connected if data viz and big flat tables are your thing.

Oh man these #PowerBI Visual Calculation things are my new happy place.

Here I'm generating dynamic chart titles efficiently, WITHOUT polluting my model with something purely used in one visual.

Fucking awesome!

Visual Calculations for #PowerBI are rocking my world and I'm only scratching the surface.

Please extend my thanks to the team that implemented these, @jaypowerbi.bsky.social - I expend SIGNIFICANT compute on formatting measures, and this is gonna make my hacks much cheaper to run.

I saw a demo of a gen AI product that converts natural language into SQL queries. With most of these products, the pitch is to give business users direct access to the data to ask things like "what were sales last year?". I have the same questions (in addition to security concerns) each time.
