Unlocking PDF files

Ok, no matter how much protection you can place in a file. Once it is able to be opened, it will be prone to copying.

For example, protected PDF files. Once you are able to print it, you can use a tool like PDF Creator, to print it, and then generate the PDF file however you like.

PDF Creator is free and can be downloaded from:

http://sourceforge.net/projects/pdfcreator/

Another option is to use the GhostScript tool. With it you can generate a new PDF file, from the original one. There is a script that already sets up the GhostScript tool and creates the requireds shortcuts in:

Uma visão sobre a educação superior no governo Lula

Um artigo da Revista Universidade e Sociedade, da associação de docentes do ensino superior. É interessante, para ver uma outra visão do assunto.

Para transferir arquivos e acessar terminais

O combo básico tem que incluir o WinSCP, e o Putty.

Para acesso via terminal. E, de quebra, o WinSCP pode funcionar como cliente de FTP simples, e o Putty, como terminal. =)

Programs that you can’t miss in your computer

To edit any audio file, you can’t go wrong with audacity, available at:

I use it to cut and paste audio files, and it works great. Simple and efficient. =)

Configuring Windows Seven Folder Templates

True, Windows 7 is here and there is no going back… But one of the things that actually piss me off is the folde template automatic configuration. It simply changes everything on the folder to match what it “believes” to be right…

But, to disable it, you just need to change Windows Registry… =)

From: http://www.sevenforums.com/tutorials/15699-folder-template-default.html

The link simply explains to add the registry value

"FolderType"="NotSpecified"

at the following key:

[HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\Bags\AllFolders\Shell]

As easy as it could be… =)
