This security-focused Linux distribution is surprisingly good for everyday use

Ger Bosma/Getty There are some Linux distributions that were created for specific purposes. There are those for creating multimedia, developing software, network routing, ethical hacking, general use, and everything in between. And then there are some distributions that can easily serve multiple purposes. When I think of ParrotOS, I generally think of security: forensics, penetration testing, etc. I've used ParrotOS for similar purposes before, but always neglected to test the Home edition.

Investors familiar with the matter told The Wall Street Journal that the rocket company SpaceX has agreed to invest a whopping $2 billion in xAI, the Musk-led firm behind the controversial large language model Grok.

Why random selection is necessary to create stable meritocratic institutions

Campbell's Law (a variant of Goodhart's Law) states that the more a metric is used for social decision-making, the more it will be subject to corruption which distorts and corrupts not only the metric itself, but the very social processes it was meant to measure. Selection criteria for a position of authority are one example of such a metric. When selection criteria are opaque, it is difficult for them to become a target, preserving their utility as measures.

Obviously, there was the iPhone 5c back in 2013 as a cheaper offering compared to the iPhone 5s. It didn’t sell too well, but it was certainly its first venture into this market.
