In front of our screens, we see multiple notes, fold- ers, windows, and applications that somehow replicate a metaphoric desk. The way we navigate this digital system has not changed much in the past four decades. How- ever, in the last two years, the technological landscape is showing sign of a potential shift that could enable novel ways of navigating the physical and digital information spaces.

Gonzalo Ord´o~nez{Matamoros Email: [email protected] Telephone: +31 53 489 3348 Office: Ravelijn RA 4333 (STEPS) 1 Abstract Open source software development is a major driver of software innovation, yet it has thus far received little attention from innovation research. One of the reasons is that conventional methods such as survey based studies or patent co-citation analysis do not work in the open source communities. In this thesis it will be shown that open source development is very accessible to study, due to its open nature, but it requires special tools. In particular, this thesis introduces the method of dependency graph analysis to study open source software devel- opment on the grandest scale. A proof of concept application of this method is done and has delivered many significant and interesting results.

  • Tutorial Do Linux
    Apostila elaborada por Fernando Henrique e Paula da Luz - [email protected] Mestrando em Física Computacional pelo Instituto de Física de São Carlos Tutorial do Linux Um pouco de História O Kernel do Linux foi inicialmente desenvolvido pelo estudante finlandês Linus Torvalds numa tentativa de conseguir o seu próprio sistema operativo semelhante ao Unix (Unix-like) que corresse em processadores Intel 80386. Linus obteve uma cópia do Minix estudou a mesma não ficando satisfeito com sua arquitetura. O projeto foi lançado em 1991 numa famosa mensagem para um grupo de discussão da Usenet. Curiosamente, o nome Linux foi criado por Ari Lemmke, administrador do site ftp.funet.fi que deu esse nome ao diretório FTP onde o kernel do linux estava inicialmente disponível (Linus tinha batizado como "Freax", inicialmente). Desde o princípio, ele recebeu a ajuda de hackers do Minix, e hoje recebe contribuições de milhares de programadores de todo mundo. Arquitetura O Linux é um núcleo (kernel) monolítico. Isto é, as funções do núcleo (agendamento de processos, gerenciamento de memória, operações de entrada e saída, acesso ao sistema de arquivos) são executadas no espaço do núcleo. Uma característica do Linux é que algumas das funções (drivers de dispositivos, suporte à rede, sistemas de arquivo, por exemplo) podem ser compiladas e executadas como módulos (LKM - loadable kernel modules), que são bibliotecas compiladas separadamente da parte principal do núcleo e podem ser carregadas e descarregadas após o núcleo estar em execução. Portabilidade Embora Linus Torvalds não tenha tido como objetivo inicial tornar o Linux um sistema portável, ele evoluiu nessa direção.
