Dados.Gov.BR
Durante as pesquisas para escrever meu último post, ví o Tim O’Reilly falando de um site do governo americano chamado data.gov. O site é um portal para se procurar e baixar informações e estatísticas em formatos puros como XML, KML, CSV etc. Achei genial e fundamental para uma gestão aberta colaborativa. Então o título deste…

A Diferença SUSE↔OpenSUSE e Red Hat↔Fedora
É ainda uma pergunta muito recorrente qual a diferença entre SUSE e OpenSUSE, Fedora e Red Hat. Por mais óbvio que seja para várias pessoas. Quando comparamos distribuições Linux como SUSE com OpenSUSE e Red Hat com Fedora, são estruturalmente idênticas mas tem alguns componentes internos que diferem na versão. Por exemplo, o OpenSUSE tem…

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,

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…
