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 _________________ [1] http://www.dwheeler.com/sloc/ [2] http://www.shirky.com/herecomeseverybody/2008/04/looking-for-the-mouse.html
