A fun few hours with Cursor, neo4j, and Cytoscape analysing astroturfing and sock-puppet accounts on Reddit.
Common pattern of a handful of accounts posting 'questions', and then another comments on it.
Maybe an attempt at seeding LLMs, which scrape Reddit?

🌶️ Hot take: if you have to label your opinion as a 'hot take'… it probably isn't.

One for my DBA friends! A very good talk from @andypavlo.bsky.social, looking at how LLMs can _actually_ be used to help improve performance. It's measured and reasonable, with plenty of caveats and real-world considerations from someone who _really_ gets RDBMS.

#duckDB question - is there a smart way to expose all the `value` string fields without manually unpacking them by name?
e.g. this is tedious:
SELECT value.animalName.string, value.deviceID.string
Sample record: gist.github.com/rmoff/38aff1...

Ended up going with asciidoc + revealJS.
Love the low friction and focus on writing.

For years I've used the "+" trick with emails when registering, and finally it paid off. Looks like surge are selling addresses (or got breached), and adobe are buying addresses for unsolicited emails ¯\_(ツ)_/¯

What *IS* an AI Agent?
To mix my metaphors: I've been pushing this one around on my plate for a while now, but it's time to ship it or get off the pot. As it were.
So…what is an Agent? Have a read of this an LMK if I'm talking complete nonsense or not ;)
