Column | De voorzichtige terugkeer van het politieke midden

Insight in the data economy:

Seems dodgy! Did I get the option to not consent? I don't recall seeing this on my last flight booking.
Airlines Sell 5 Billion Plane Ticket Records to the Government For Warrantless Searching
New documents obtained by 404 Media show how a data broker owned by American Airlines, United, Delta, and many other airlines is selling masses of passenger data to the U.S. government.

Barbara Kathmann heeft fantastisch werk gedaan op het gebied van digitalisering en privacy, maar haar indrukwekkende prestaties op deze portefeuille kregen van de kandidatencommissie verrassend genoeg niet de waardering die ze verdienen.

An 8TB corpus of copyright-free text for training AI models.

https://github.com/r-three/common-pile/blob/main/paper.pdf

I'm glad somebody has finally done this. The "we need to break copyright or AI won't work argument" feels super-dodgy to me and we can just evaluate whether it's true. 1/n
A diagram showing the breakdown of the Common Pile corpus. It shows large chunks coming from Code, wikimedia, stackexchange etc.

This is genius. If I’m understanding correctly, metadata is handled by a DuckDB compatible SQL database and the actual data is handled by an open file format of your choice.

You can perform familiar SQL queries and DDL, on highly scalable open format data files. Well done! #databs #dataengineering

Today we're launching DuckLake, an integrated data lake and catalog format powered by SQL. DuckLake unlocks next-generation data warehousing where compute is local, consistency central, and storage scales till infinity. ⁠ducklake is an open standard and we implemented it in the "ducklake" extension.
