Published: Wed, 26 Nov 2008 15:00:11 +0000 Updated: Wed, 29 Apr 2009 22:21:37 +0000 | 13 comments

I love to see crackers attacking my computers. I even wrote a Linux Magazine article about a successful invasion (portuguese).

É importante enfatizar que a Microsoft anda dizendo que o OOXML é bom e necessário porque garante compatibilidade com o formato anterior (.doc etc).

Isso é uma imprecisão grosseira que cai bem nos ouvidos de quem não é técnico ou quem não pára pra pensar o que isso significa.

Explico: O .doc e companhia são formatos binários [...]

There are some news popping on the web about ODF to be substituted by W3C’s Compound Document Formats.
