Linux and english19 Mar 2008 05:21 pm

The Australian PC World edition created an interesting Quiz about some historical Linux facts. The quiz has 10 questions ans they are very nice to check if you remember dates and name of the companies and persons from the first years of Linux.

I did the quiz, and my score was not good: 60% (for me a good score should be more than 80%).

If you have more than 12 years of Linux usage or think that know all about the Linux history, check your knowledge  here.

Have Fun!

Gnome and Ubuntu and english11 Mar 2008 10:59 am

I’m glad that my blog is working for something :-D Mark Lee saw my other post about the AWN on Ubuntu, and send me a comment about the incorrect repository link that I used.

Actually, the repository is not incorrect, but the owner has moved the repository to Launchpad, and the repository URL(s) have changed. So, here is the new URLs that you need add in your /etc/apt/sources.list file:

  1. deb http://ppa.launchpad.net/reacocard-awn/ubuntu gutsy main
  2. deb-src http://ppa.launchpad.net/reacocard-awn/ubuntu gutsy main

Then, execute:

  1. sudo apt-get update
  2. sudo apt-get install avant-window-navigator-bzr awn-core-applets-bzr

For more information, see the official thread about the issue http://ubuntuforums.org/showthread.php?t=385981

Funções ZZ and Shell and Unix and portuguese04 Mar 2008 10:09 pm

Criadas em fevereiro de 2000, as Funções ZZ acabaram de completar oito anos de existência. Neste período, vários projetos livres nasceram e sumiram, mas as funções conseguiram perseverar. Para comemorar esta conquista, foi lançada a versão 8.3, repleta de novidades.

Esta versão nova é um divisor de águas no desenvolvimentos do programa. O código foi completamente rescrito, visando segurança, legibilidade e facilidade de manutenção. Com comentários em português e algoritmos simplificados, seu código-fonte é um prato cheio para estudantes de Shell Script. Está tudo muito claro, fácil de entender.

Outra grande mudança é que agora o UTF-8 é a codificação padrão das funções, garantindo seu funcionamento nos sistemas modernos e acabando de vez com os problemas de acentuação. Os usuários que ainda utilizam o ISO-8859-1 não foram esquecidos, pois há também uma versão especial que vai funcionar em seus sistemas.

Agora o funcionamento correto das funções é garantido por uma suíte de testes automatizada que conta com mais de 550 verificações, fazendo um controle de qualidade rigoroso. Uma equipe de voluntários roda estes testes em diversos sistemas, ajudando a encontrar e resolver problemas. Há também duas funções novas: zzbyte para conversões entre grandezas de bits e zztool para validação de textos e arquivos.

Para completar este processo de amadurecimento das funções, o seu site www.funcoeszz.net foi remodelado, ficando mais intuitivo e fácil de encontrar as informações. Que tal uma visita agora para conhecer melhor as funções?

Funções ZZ é um software livre 100% nacional que reúne dezenas (65 atualmente) de mini-aplicativos de linha de comando, que funcionam no Linux, Mac e Windows. São várias funções em shell Bash para cálculos com datas, validação de CPF/CNPJ, arrumar nomes de arquivos, gerar senha, buscar notícias na Internet, obter o resultado da Mega-Sena, consultar a Wikipédia, pesquisar no Google e traduzir textos, entre outras. A dupla de autores é Aurélio Marinho Jargas e Thobias Salazar Trevisan.

HPC and IBM and Supercomputing and english01 Mar 2008 12:38 am

A little post that I posted in my IBM internal blog.

Ok, everyone has heard about the Top500 list, a twice year list of the sites operating the 500 most powerful supercomputers systems of the world. The first list is commonly announced during the International SuperComputing Conference - ISC (June), and the second during the International Conference for High Performance Computing, Networking, Storage, and Analysis - SC (November).

The first position of the last list (released on November 12th, 2007) is the BlueGene/L System, a joint development of IBM and the Department of Energy’s (DOE) National Nuclear Security Administration (NNSA) that was installed at DOE’s Lawrence Livermore National Laboratory in Livermore, Calif. The No. 2 is from IBM too, a BlueGene/P system installed in Germany at the Forschungszentrum Juelich (FZJ). From the Top10, there are four IBM’s systems, and 46.6% of the 500 systems are IBM.

And about the Green500 list, who’s know it? The Green500 provides a ranking of the most energy-efficient supercomputers in the world and serve as a complementary view to the Top500 list. The first list was announced on November 15th, 2007 at SC07, and we can see the rank here.

But why is it important to IBM? Because the numbers!! From the first until the 27th position, only the No. 6 is not from IBM. The first five systems are Blue Gene/P Solution, and from the No. 7 until the No. 27 they are eServer Blue Gene Solutions.

This is a clear result of the green concern that IBM is involved.
