II ciência livre – semana de ciência e tecnologia 2010

o que é software livre?

o que é software?

programas, aplicativos, ferramentas, utilitários...

sequência organizada de passos

um software é uma receita

diz perfeitamente ao computador o que fazer :)

softwares são feitos por pessoas

às vezes, muitas pessoas!

?----------->

linguagem de programação!

java

c

visualbasic

...várias tecnologias....

muitas mesmo!

----------->

----------->

código-fonte executável

compilação

nessa ordem

<-----------

código-fonte executável

faça seu software como quiser

...livre...

e deixe-o livre, se quiser!

software livre

use

distribua

estude

modifique

sem restrições

sem letras miúdas

mas espere...

“programa de graça”

“chega de serial”

não é isso!

<-----------

código-fonte executável

----------->

você não é refém do software

usar, redistribuir, estudar, modificar

usar, redistribuir, estudar, modificar

mascote do linux

mascote do linux

láinãcs? láinux?

linux!

o mais famoso software livre

e possivelmente o maior

x 460

linus torvalds

linux é um sistema operacional

sistemas operacionais em mobiles

android

baseado em linux

sistemas linux são distribuições

e existem várias....

...várias mesmo...

é absurdo.

quer experimentar uma?

tente o ubuntu

provavelmente alguém perto de você usa :D

sabia que vc já é usuário de software livre?

web se baseia em software livre

linguagens, formatos, protocolos, sistemas

abertura = interoperabilidade

formatos fechados = usuário refém

formatos abertos = liberdade de escolha

infinitas possiblidades

tudo isso é muito bonito

empresas financiam!

empresas não são santas

testar exaustivamente pode ser caro

muita gente usa testa os softwares livres

muita gente mesmo

usuários corrigem/reportam bugs

treinamento, suporte, certificação, equipamentos, customização

todo mundo ganha com software bom

software livre tende a ser mais seguro

peer reviewing

algumas opiniões

vivemos em comunidade

compartilhamos livros

Idéias, opiniões

músicas

vídeos

conhecimento

receitas de bolo :)

porque não compartilhar software?

não seja egoísta!

remixe

produza

não fique de fora

há uma revolução acontecendo

junte se a nós :)
