Shutting down the podcast and leaving Data Masterminds brought relief, not grief. 2025 taught me that outdated identity narratives are self-reinforcing data points, not destiny - and that most organizations prefer data theater over actual insight.

I just had an extremely enlightening hour with @sqlgene.com . Not only did I learn much, much more than I thought I would, but I also learned much, much more about what I didn't know that I do not know. A huge thank you to Eugene for educating me.

You think ChatGPT is thinking? It's rolling dice token by token, without planning ahead. Non-English users get fundamentally worse performance. What's actually happening under the hood?

Four months of LLM use = measurable brain decline. Like GPS destroyed spatial navigation, AI atrophies thinking. Let's talk about the research, warning signs, workplace implications, and practical solutions.

LLMs are pattern-matching engines, not thinking machines. But anthropomorphization plus dopamine-driven addiction pathways trick us into trusting them. Learn what they actually are and why understanding this matters.

Rituals help performers access their best state. While power posing failed, pre-performance psychology works - discover why rituals create mental anchors!.

Sugar went from luxury to ubiquitous poison before we understood what it was doing to us. We're doing the exact same thing with AI, adding it to everything without genuine use cases while it erodes literacy and critical thinking. #AI #Literacy

Power BI, the low-code tool 🤡🫣🤭
We finally have 𝘂𝘀𝗲𝗿-𝗱𝗲𝗳𝗶𝗻𝗲𝗱 𝗳𝘂𝗻𝗰𝘁𝗶𝗼𝗻𝘀 (𝗨𝗗𝗙) in DAX!

Don't make mistakes; this is not a user data function in Fabric.

This is a new DAX feature, the most important one in the last five years.

Glorious! @effinbirds.com on LinkedIn of all places. And it's perfect. The level of superficial bollucks interspaced with pure unadulterated "f'ck this shit" makes it much more bearable and entertaining. Highly recommended.

Claude has now failed miserably for the last few hours to help me deal with what most likely is a fairly simple task in Azure Devops pipelines. The so-called "AI" is not coming for our jobs anytime soon.

For anyone considering taking the trains in Sweden: don't. I've had the misfortune of having to endure multiple train rides this year, and all of them have been between 20 minutes and 2 hours late. Currently standing still somewhere on the track after another "electrical issue".

An absolutely amazing piece of writing that summarizes my view on "AI" very well. I am not against machine learning - quite the opposite - but treat it like the tool it is and do not try to use it for everything under the sun, all while saying it will be the panacea for everything conceivable.

Many ask themselves, «Why would I use a semantic layer? How to build one?».

But a better question is: How many times have you implemented the same revenue calculation differently across your company's dashboards, reports, and apps? This is why semantic layers exist.

I have a love/hate relationship with Rode. Excellent hardware, absolutely dogshit software, and the only thing the "support" says is to send in the device - which, as you might expect, will do NOTHING for said useless and buggy software.
