I just published my first post on Embabel’s Medium, about property filtering. This feature lets LLMs populate only approved fields, keeping hallucinations out of domain entities and enabling safe reuse in agent workflows.

I admire the Dutch for many reasons, one of which is that they celebrate the New Year with doughnuts. I’ve taken a leaf out of their book, and so Oliebollen, the doughnuts in question, are #RecipeOfTheDay.

Today we played our 40th and final session of Black Lancers, my WW2 Pulp Cthulhu campaign following the trail of the Polish Black Brigade through Europe, as the heroes hunt for ancient Christian artifacts.
This was the 2nd time I have run this campaign, and it has been a joy from start to finish.

@clownf1st.bsky.social there is a new comic describing the events that happened on the Batavia in 1629. I think you recommended Mike Dash’s book to me at GROGmeet 2019.
The comic is in Dutch, unfortunately, perhaps a translation is forthcoming.

Fun Dutch fact: Claude sounds like kloot (“testicle”), as in verkloten (“to fuck up”).
So Claude fucked up the code becomes “Claude heeft de code verkloot”, which rhymes.
