[Nick Demou]

με βάση το εξαιρετικά ενδιαφέρον αλλά "σιτεμένο" [1]:
Red Hat 6.2: ~19 million lines of code, about 5,000 person-years of
development time
Red Hat 7.1:  30 million physical source lines of code, about 8,000
person-years of development time
Debian 3.1: 230 million lines of code, about 60,000 person-years [more
than 100 million hours of human thought]
                  (περίπου $8 billion USD redevelopment cost)

και μετά διαβάζω στο εξαιρετικά ενδιαφέρον και φρέσκο "Gin,
Television, and Social Surplus"[2]
<<<<<<
all of Wikipedia, the whole project--every page, every edit, every
talk page, every line of code, in every language that Wikipedia exists
in--that represents something like the cumulation of 100 million hours
of human thought.[...] it's a back-of-the-envelope calculation, but
it's the right order of magnitude
[...]
And television watching? Two hundred billion hours, in the U.S. alone,
every year. Put another way, now that we have a unit, that's 2,000
Wikipedia projects a year spent watching television.

και ο συγγραφέας του "Gin, Television, and Social Surplus" καταλήγει:
<<<<<<
[...] they're discovering that when you offer people the opportunity
to produce and to share, they'll take you up on that offer. It doesn't
mean that we'll never sit around mindlessly watching Scrubs on the
couch. It just means we'll do it less.

And this is the other thing about the size of the cognitive surplus
we're talking about. It's so large that even a small change could have
huge ramifications. Let's say that everything stays 99 percent the
same, that people watch 99 percent as much television as they used to,
but 1 percent of that is carved out for producing and for sharing. The
Internet-connected population watches roughly a trillion hours of TV a
year. That's about five times the size of the annual U.S. consumption.
One per cent of that  is 100 Wikipedia projects per year worth of
participation.

I think that's going to be a big deal. Don't you?

Και σε αυτό το σημείο ζητώ συγνώμη γιατί από μια άποψη το post είναι
ελαφρά off topic
