Don't panic!

Po čemu je razvoj Linuxa drugačiji od ostalih operacijskih ustava?

Što su distribucije, zašto postoje i po čemu su slične i različite?

Zašto postoje zajednice korisnika Linuxa? Zar nisu komercijalni dobavljači dovoljni?

Povijest Linuxa počinje 1991.

Linus Torvalds je želio OS sukladan sa Unixom za svoje i386 PC računalo

odlučio se za često objavljivanje novih verzija na Internetu i GPL licencu

BSD je imao nejasnu pravnu stranu

If you want to travel around the world and be invited to speak at a lot of different places, just write a Unix operating system. --Linus

GPL licenca i izvorni kod

GPL potiče razvoj nove programske podrške pod GPLom (viralan je) i prodaju usluga (prilagodbi) a ne produkata.

Basically, I want people to know that when they use binary-only modules, it's THEIR problem. I want people to know that in their bones, and I want it shouted out from the rooftops. I want people to wake up in a cold sweat every once in a while if they use binary-only modules. --LINUS

Razvoj jezgre Linuxa

povijesno

stabilne verzije (1.0, 1.2, 2.0*, 2.2, 2.4, 2.6)

development verzije (0.9, 1.1, 1.3, 2.1, 2.3, 2.5, ?)

2.6 jezgra je razvojna i development!

*) 1996. linux postaje 64 bitan operacijski sustav za Alpha procesore

'Fewer fundamental changes' is a mark of a system that isn't evolving as quickly, and that is reaching middle age. We are probably not quite there yet --Linus

Veza Linuxa i GNU projekta

sama jezgra OS-a nije dovoljna

korisnički programi su dio GNU projekta

svaki puta kada pišete ls na Linuxu koristite program pod GPL licencom koji je napisan kao dio ”Gnu is Not Unix” projekta

We all know Linux is great. It does infinite loops in 5 seconds. --Linus

GNU/Linux distribucije

slobodne i besplatne

Fedora

rpm

Debian

deb

Gentoo

portage

komercijalne sa podrškom

RedHat Advanced Server

SuSE/Novell

Linux Standard Base

Podrška za Linux

komercijalna podrška

u hrvatskoj još uvijek nedovoljno fleksibilna

podrška zajednice Linux korisnika

najbolji izbor informacija i savjeta

The best part is definitely the community - there are downsides to that too, but on the whole it's really great to interact with people and have a lot of people you know. --Linus

Dakle, što sa Linuxom?

Linux može odraditi enterprise zadatke

podrška postoji (korisnici Linuxa i vendori)

ulaganje u znanje vlastitih ljudi se isplati

I'm never in the situation where I have to make a priority-decision between Linux and money - all my Linux-related work can be done purely on technical issues rather than having any "marketing" issues pop up. --Linus
