Ontem à noite não tinha nada melhor pra fazer, instalei o Fedora 10 lá em casa.

Não vou fazer nenhum review aqui. Tem muito site que faz isso, e faz com maestria.

Só queria comentar que há alguns releases atrás, quando inventaram o tal do Codeine, que servia para os codecs necessários para rodar um arquivo de mídia, a idéia era boa, mas a execução era porca. O Totem (ou Rythmbox) abria uma janela dizendo o que estava disponível gratuito, e o que seria pago. A instalação era terrível, e nem sempre funcionava.

Já no Fedora 10 isso foi integrado ao PackageKit, e essa integração ficou fenomenal. Ontem fiz uns testes com vídeos em DivX, e de primeira ele detectou os codecs faltando, e tentou baixar os pacotes. Obviamente não havia nada, já que por padrão o Fedora não libera pacotes com codecs não-livres (ref). Ok, pode não ser muito óbvio para quem não está acostumado, mas é assim que funciona no Fedora.

E como contornar? Para isso existe o RPM Fusion, um repositório de pacotes que não podem ser distribuídos pelo Fedora por uma ou outra restriçao. Adicionando esse repositório ao seu sistema, o PackageKit encontra facilmente os plugins to Gstreamer (Totem/Rythmbox) que permitem o uso de vários tipos de vídeos proprietários ou não-livres.

Muito bom! Estamos caminhando para a integração total entre o desktop e o “fornecedor de software”, já que uma das reclamações mais constantes que ouço é que é muito difícil instalar um programa no Linux, muito mais ainda saber de onde instalar.

O Projeto Fedora, juntamente com o time RPM Fusion, anunciam ao público o mais novo repositório para o Fedora. o RPM Fusion proverá pacotes que estão fora dos repositórios oficiais.

Mas o que é o projeto RPM Fusion? O projeto é a junção de vários repositórios que forneciam pacotes que estavam fora do repositórios oficial do Fedora, assim, algumas vezes, gerando quebra de dependência, quando esses vários desses repositórios em um único sistema.

There are a lot of different stories about what motivated the creation of the Fedora Project. Well, in this video, you can find a view from who was there, and participated in the whole process. Check out Greg DeKoenigsberg’s view of the facts.

Someone sent us a request today.

I have been brutally separated from my iPhone in an unfortunate event.

[Update]: Uh! This is post 300!

Today the LHC (Large Hadron Collider) from CERN (European Organization for Nuclear Research) starts it’s operation. This is a huge particle accelerator (also widely known as “the largest machine built by man”) which will try to reproduce the conditions that existed only during the Big Bang, and also try to detect and prove the existence of many particles only known in theory (so far).

- LHC at Wikipedia
- Special website from Nature
- Coverage from Scientific American

Some say this is the prelude to the end of the world, but that’s just human nature. Usually people are scared about things they don’t know or don’t understand. For those people, today is the first day towards the end.

For those who believe the LHC is a benefit to humanity, we can only hope that with the experiments we can finally understand black holes, worm holes, big bang, or even time travel and parallel dimensions.

Let History define who’s right and who’s wrong.

ramkumar commented on an earlier post called “RH401: Passed” that he didn’t know what RHCDS mean. To serve a wider public, I am going to post a few links of interest for those who want to understand what goes around Red Hat Certifications:

• Red Hat Training main page
• .RHCE - This is the regular certification. It means you are able to manage Red Hat systems in a general manner.
• RHCDS - This certifies that you are a little over a regular administrator, and you have datacenter skills.
• RHCSS - This certifies your skills/knowledge of fine tuning security on Red Hat systems.
• RHCA - This certifies that you have further knowledge, and is prepared for the “enterprise” systems (clusters, virtualization, etc).

Some of the courses overlap, some are specific. Read the descriptions, check the courses, and define your path.

I don’t know worldwide, but I can say that in USA and Brazil, RHCE is a pretty strong certification (better than LPI), and RHCA is rapdly becoming of higher importance.

Have fun!

Today someone asked me to help with a computer crash. I replied “try this, try that, then let me know if it works”. Fine minutes later, he replied to my e-mail with a URL:

Uh, right. I got the message, sorry.

Raleigh, N.C.-based Red Hat Inc. has touted its “green computing” image following a recent independent test that ranked Red Hat Enterprise Linux (RHEL) 5’s power efficiency over Novell’s SUSE Linux Enterprise and Microsoft Windows Server 2008 on three different hardware platforms.

The server tests rated power consumption on IBM, Dell and HP machines in three conditions: active mode optimized for power savings, active mode optimized for performance and quiet mode.

A small newspaper in Brazil came out today with the following photo in it’s cover.
