I would have thought that the trick of having my LinkedIn name as “📊 David” to identify spammers would have stopped working after 5 years, but it’s still going strong.
“Hi 📊 David, I was reading your profile and you would be perfect for this role…”

Any system that allows exchanging real money for stuff with an element of chance is morally equivalent to a casino.
Corollary: Pokémon cards, Roblox, Labubus, and even claw machines should all be 18+

Yesssss random forests.
Gradient boosting the is the stage where I mostly get the concept but my understanding isn’t 100% clear. But random forests are the most complicated models where I feel like I properly understand them top to the bottom.

I don't really have favorites (I contain multitudes), and until i saw @christophmolnar.bsky.social ask this funny question, I don't think I'd realized how enamored I am of SVMs. They're just so beautiful, especially radial SVM.
Also on my list of loves: KNN!

Experimenting with a custom made static site generator. Super simple stuff: a build script that uses pandoc to convert markdown to HTML and then spatchcock it into a template file. Surprisingly successful so far

At this point I’ve just made peace with the fact that divs cannot be centred and I’m much happier for it. Blessed is the mind too small for CSS

The worst thing about notebooks isn’t that they’re an incentive to write horrendously unstructured code, but that they displace proper IDEs. Lots of data science tooling is built with a mindset of “data scientists only use Jupyter”.

No, Australia does not need new cities.
My new essay sets the record straight: we have a lot of cities, but we aren’t using them as well as we could be. To make our cities more successful, we have to open up a lot more land for commercial uses to enable agglomeration.

Why do you think this NIMBY considers London, New York and Los Angeles to be good, but Hong Kong, Bangkok, and Mexico City are bad? What's the difference? What could be the distinguishing factors there? What a mystery!

I’m running trouble with Python’s philosophy of “there should be multiple ways to do it”.
I want a function to work with both pandas and polars columns, so I need to import both in my module even though users will only be importing one? That can’t possibly be right.

Speculation: LLMs are useless at explaining enterprise software because the training data and search results are mostly marketing bullshit.
So if I say “tell me what $x does” I’ll get “$x leverages cutting-edge AI, empowering organisations to unlock transformational insights”
