Free software

● “Free” - sloboda, ne cena

● “Free as in freedom”

● "Free as in beer" vs "Free as in speech"

● Besplatan vs slobodan

Milan Milošević, 14-16. oktobar 2009, Pirot www.mmilan.com

Besplatan softver?

● Vlasnički softver
● Freeware
● Shareware (?!?!)

Zašto?

● I need, I want, I CAN

● Niko ne radi besplatno ?!?
● Neko radi zbog zabave
● Neko radi zbog potrebe

● “Novi” poslovni model
● Cena usluge, ne proizvoda

Zašto ja?

● Korisnik
● Cena, stabilnost, bezbednost
● Kompanije
● Kompatibilnost, nezavisnost, cena
● Čovečanstvo
● Monopol, znanje, sigurnost, nema “Velikog brata”


Ali...

● Već koristite Slobodan softver !
● Firefox
● Wikipedia
● Internet...


GNU is Not Unix

● 1969: Nastao Unix (AT&T)
● 1983: Startovao GNU Projekat (Richard Stallman)
● 1991: Linux 0.01 ( 10k linija koda, 1 korisnik )
● 1994: Linux 1.0 ( 170k linija, 100 hiljada korisnika)
● 1996: Linux 2.0 ( 400k linija, 1,5 miliona korisnika)
● 1998: Free Software Definition (4 slobode)
● 1998: Linux 2.1.11 ( 1.5M linija, 7.5 miliona korisniak)
● 1999: Linux 2.2: 12 miliona korisnika
● 2009: Odlična budućnost

GNU/Linux

Prednosti:

● Brzina i stabilnost
● Bolji kvalitet i ekonomičnost
● Bezbednost: manje “rupa” brze i češće “zakrpe”
● Nema crva, spyware-a, rušenja, plavog ekrana
● Pravi višekorisnički sistem (pristup fajlovima, prava drugih
korisnika, morate da se prijavite)
● Prilagodljivost (Mogućnost izbora, CLI, GUI,...).
● Jaka zajednica za podršku i razvoj


Ako je tako dobar...

● ...zašto se ne koristi više?
● Skuplje = bolje
● Marketing
● Kompanije, ugovori, obaveze
● Piraterija
“It’s easier for our software to compete with Linux when
there’s piracy than when there’s not.” - Bill Gates (2007)
“They’ll get sort of addicted, and then we’ll somehow figure
out how to collect sometime in the next decade.” Bill Gates
(2006)
