Programs will usually start with capabilities, perform any activities that require those capabilities, and then “drop” them when the process no longer needs them. This, in turn, allows processes to exercise certain privileges without having any privileges in the init user namespace. User Namespaces Fortunately, Linux has a solution?

The resulting program preserves the original structure, and contains all vulnerable operations.

If we don’t exercise our muscles, they tend to atrophy, but we still have them. Once we begin to exercise, the muscles grow again. People who have exercised innate capabilities and acquired developed capabilities will be much better positioned to acquire whatever skills they need to be successful. We all have muscles as humans.

While it is seen as a positive for users to be able to quickly see if the site they’re loading is slow, the ethics of such a program become a little murkier.

To borrow Henry Ford’s alleged words, it would be great at designing faster horses, if asked.

It’s also awkward, an exercise of the blindfolded people describing the pachyderm. Some of this is likely a function of professional programming: if, for the totality of your career, the boss has supplied you with the reason why you do the things that you do, it isn’t natural to start a new initiative by asking “why”. And that’s ok.

Software today is not typically a single program—something that is executed by an operator or user, producing a result to that person—but rather a service : something that runs for the benefit of its consumers, a provider of value. The most common programming task in the world. Let’s dive into this concept for a bit.

This ruling in itself raises many questions: how much creativity is needed, and is that the same kind of creativity that an artist exercises with a paintbrush? However, that design issue isn’t germane to this discussion. If a human writes software to generate prompts that in turn generate an image, is that copyrightable?

"Appiness" is an illusion, an arbitrary line drawn to include programs built on some platforms but not others, and all of today's OSes allow multiple platforms to expose "real apps."
