There are no longer any excuses for a Minimum Viable Product. From now on, an MVP should be a Maximum Valuable Product, as the SQLBI Whiteboard story teaches us.

Idea: ask your boss for a larger monitor.
How many slicers did your last report have? Who holds the record?

@fhtino Uncertain. For sure, that 5% is not needed often.

Are LLMs now better at DAX than humans? My honest answer, from the DAXBench v2 live with Maxim Anatsko.

@kurtbuhler It’s like they made RL using only marketing brochures from IT companies but it’s too scary so it cannot be that.

Yesterday's article on optimizing DAX with AI was supposed to come with a video, and the video was missing at launch. Now it's online: the same test, human vs AI vs human plus AI, in video form.

We optimized a DAX measure ourselves and asked AI to do the same. Neither version was faster on every query.

Then AI refined our version: the slowest query went from 4,396 ms to 1,538 ms.

It also wrote more equivalence tests than we ever had the patience to write.

DAX with AI: Scenarios is complete!

The video course includes ten business scenarios: currency conversion, comparable-store sales, budget vs. forecast, shared-cost allocation, inventory from sparse snapshots, financial statements, workforce analytics, and more. The training also includes seven "concept" lessons that are shared across several scenarios.

We announced it in September for November 30, and we're proud to release it four weeks early.

If you already purchased the video course, log in to your SQLBI account: the whole training is ready for you!

You don't need to watch it from start to finish (but you can if you want to): Pick the scenario closest to your next project, check the concepts it lists, and start there.

The details are in my blog post: https://t.co/xgmk3vRiiz
If you haven't enrolled yet, there's a launch offer on the course and on the bundle: https://t.co/QXs75tTdaA

@rbutinar Thank you!

[Marco Russo @marcorus]

Over the last few months, I've started writing essays that aren't strictly technical; they are more about how we work, think, and build things.
I also created a website that collects everything I publish, because with AI, I no longer have an excuse to postpone it: https://t.co/ty4FBqCwei

Here are the essays so far:

- The orchestra conductor
- Code as a hobby
- No SQL, no analyst
- Function first

This is still the place for the conversation: your feedback is very welcome!

@ilya_sb1 there is never a single truth. The comics highlight the issue of having different interpretations of the same metric definition.

[Marco Russo @marcorus]

Be honest: when the numbers disagree, does the truth win or the nicest number?

[Marco Russo @marcorus]

@LucidInsightsNZ Indeed that’s the question!
