A textbook case: public funds burned for years on a service that was never viable. The money's gone, the work's gone, and predictably, so is the project. Same old story.
Which public funds ? DNS0.eu was a private initiative, from the NextDNS founders. DNS4EU is a public initiative, as mentioned in the news, and this one is still supported and actively developed.
Second bullet point is pretty funny. I really liked linear algebra, but I'm sure it could get frustrating if you're not an expert. I wonder if it makes sense philosophically for code to be more mathematical like APL or like a spoken language like Python.
