Spain could have been a scientific superpower; but the Reconquista brought them intellectual & infrastructural ruin.

curl, which is one of the most popular CLI/API tools for network requests and data transfer on Linux/Unix, is to discontinue its HackerOne bug bounty program due to "too strong incentives to find and make up 'problems' in bad faith that cause overload and abuse".

AI eats its users: Eurasia Group's #8 Top Risk of 2026

Under pressure to generate revenue and justify sky-high valuations, some AI companies will adopt extractive business models that threaten social and political stability.

"Do you know where I can look up Frungal's Extractor?"

The magic school librarian sighed. "That grimoire is locked away."

"Why?"

"That spell extracts your anxieties and fears and turns them into a creature."

"Yes! To slay!"

"In theory. In practice, nobody can slay the new pet they created."
