Freshly, I had only read the page you linked and was turned off at its specificity. Views of hackers (even widely-shared ones) do not constitute a definition for what a hacker
is.
The previous entry ("hacker") gets a bit more general, but is still quite computer-centric. It references non-computer activities to show that there is more to it, but does not really attempt to capture how these aspects fit together.
Specific quotes that I liked from the article:
>> Hackers believe that essential lessons can be learned about the systems – about the world – from taking things apart, seeing how they work, and using this knowledge to create new and even more interesting things.
> the archetype of ‘the hacker’ is essentially that of an individual attempting to live an empowered and unalienated life. It is outsider in spirit, seeking empowerment outside the terms set by the mainstream establishment.
> unlike the straightforward activist who defines himself in direct opposition to existing systems, hackers work obliquely. The hacker is ambiguous, specialising in deviance from established boundaries, including ideological battle lines. It’s a trickster spirit, subversive and hard to pin down. And, arguably, rather than aiming towards some specific reformist end, the hacker spirit is a ‘way of being’, an attitude towards the world.
Now gosh maybe this is really just overgeneralizing "hacker" into a fancy word for critical thinking by someone who sees through groupthink and happens to be at the right place at the right time to do something clever. But if there's an aspect to "hacker" that means something beyond just someone who plays with computers, I'd say the article did a pretty good job trying to describe that general concept.
