I genuinely don't understand the idea of buying Greenland -- do countries just sell parts of themselves? Like can we just sell Florida?

Men don’t call a woman a fucking bitch when they’re afraid for their lives—they say it when they hate us. They say it when they’re punishing us.

I'm really appreciating that just as I enter my Typo Era, AI text generation has gotten good enough to make perfect text unappealing.

I put this on LinkedIn because that's where I think folks need to hear it, but TLDR: if you're on X, GTFO.

Renee Nicole Good is the one whose reputation should be protected, whose death should be marked by flags across the country being lowered to half-staff, who should be getting tearful tributes and acknowledgments from politicians and media figures. These are the people we ought to honor.

In the last month? Tried to climb up on a step stool with one foot while my other foot was somehow underneath the step stool. Fell over. Luckily just a weird bruise from that one!
What's the most ridiculous way you ever hurt yourself? I got out of the tub, skidded in water and tripped over the toilet. Ankle sprain.

This is an excellent idea, data folks.
Trump has largely lost his ability to summon multi-syllabic words, or much of anything beyond the 1,000 most common words in English.

To no one’s surprise, the secret history of RPGs has always been women innovating ideas that men “discover” anywhere from 10-400 years later! Fantastic thread from one of the hobby’s coolest academics.
Indeed. The purchaseable *product* we call the TTRPG begins in the 1970s with Western Gunfight, Chainmail, and D&D.
Yet role-playing "parlor games," simulations, and similar are centuries old and draw from a well that resembles all the positive stuff about D&D.
Parlor games were feminized...

Let's pretend for a minute that a technical definition would matter, and unfortunately --
Even from a technical point of view there's no clear definition of what is "GenAI" and what isn't.

"Synthetic Panels" make no sense. The LLM is trained on data from a particular point in time. This is the same as querying the distribution of responses from an LLM with built-in assumptions about what the distribution can look like.
Well done surveys are designed for the opposite.

Did you know that from tomorrow, Qualtrics is offering synthetic panels (AI-generated participants)?
Follow me down a rabbit hole I'm calling "doing science is tough and I'm so busy, can't we just make up participants?"

Just enough snark mixed with optimism, with some definitely insightful thoughts on how the software engineering profession is evolving.

Too many people want to use AI for the output, when the hard part is what to ask for and what good looks like and context management.
If I were building something new I'd build an executive functioning buddy; let the machine manage context and coherence, and leave me to do the fun parts.
