  • MS Office 2007 já suporta ODF

    A Microsoft anunciou ontem o suporte de leitura, modificação e gravação de documentos OpenDocument Format (nativo do OpenOffice.org e seus derivados) no Service Pack 2 do Office 2007. A ODF Alliance soltou uma nota de boas vindas da MS a comunidade ODF, que eu endosso. Endosso também uma observação do meu colega Roberto Salomon sobre…

  • A Media Center at Home

    Since we got a 52″ Samsung LCD TV almost a year ago as a gift from relatives, I knew it was time to attach to it a dedicated computer and have a full digital media experience in the living room. I’ll tell you here my experiences building and running this thing that makes all my…

  • Cara Comunidade Debian e Ubuntu,

    Gostaria de saber o termômetro de uso do Debian e do Ubuntu em vossas empresas, escolas e comunidades. Ubuntu está mais no desktop? Já migrou para os servidores ? Ubuntu domina o desktop e Debian o servidor ? Windows no desktop e Linux no servidor? Qual Linux ? Nem um nem outro ? Abra seu…

  • I was invaded again: more passwords for you not to use

    It took some time to have my honeypot invaded again in a useful way. They were attacking constantly but were using it only to connect to IRC rooms. Useless for me. But yesterday a sweet cracker invaded it again and left behind about 240000 non-unique combinations of user+password he was using to invade others. They…

  • WordPress 2.7 Eye Candy

    Although WordPress 2.7 is almost only eye candy, it is great useful eye candy. The user interface is much much more practical, AJAXed, nice and fast. I recommend an immediate upgrade. It worked flawlessly with my complex homemade theme, my homemade plugins, plus all other plugins I use throughout my blog.

  • Yawasp Ultimate Anti-Spam Solution

    Spam fighting is a difficult job. Many spammers are too smart for Akismet and I was spending too much time cleaning comment spam. Captcha-based anti-spam methods are ok but they hurt too much the usability and user experience. Then I finally found Yawasp WordPress plugin that implements an innovative anti-spam method. It makes the comment…

  • Compromised Passwords

    I love to see crackers attacking my computers. I even wrote a Linux Magazine article about a successful invasion (portuguese). Since recently, I leave a virtual machine with an easy password ready to be attacked, just to see these crackers’ leftovers, their rootkits and what they’ll do once they brake into my system. Guess what.…

  • Mac OS X as a Virtual Machine

    Pay attention to this screenshot. This is Mac OS running as a VMware virtual machine. Pretty cool as a proof of technology. But let me tell you, this is quite a useless virtual brick. The UI is extremely slow. I had to remove the background to improve it a little bit but couldn’t resize to…

  • Dois computadores na palma da minha mão

    Da série Crônicas de TI Moderna, tenho essa foto para lhes mostrar. O cara chegou na sala, esticou o braço segurando isso pela correntinha e disse: “Estou com as duas VMs aqui”. Tratava-se desse minúsculo flash drive USB de 8GB, carregando duas máquinas virtuais de 4GB cada. E me lembrei daquele artigo sobre Paravirtualização onde…

  • Mini Papers: Pílulas de Conhecimento

    Alguns anos atrás começamos uma iniciativa na IBM de publicar regularmente artigos curtos que abordam temas de Tecnologia da Informação, suas aplicações e impacto nos negócios e na sociedade. São chamados de Mini Papers e recentemente começamos a publicá-los no portal developerWorks, em um formato de blog. Tem até um feed para os ávidos leitores.…
