DirSync Pro (Directory Synchronize Pro) is a small, but powerful utility for file and folder synchronization. DirSync Pro can be used to synchronize the content of one or many folders recursively.
Using DirSync Pro you can make incremental backups. In this way you'll spare lots of time because you don't have to copy all the files each time you want to update your backup; only new/modified/larger files would be copied.
Use DirSync Pro to easily synchronize files from your desktop PC to your USB-stick (PDA, Notebook, ...). Use this USB-stick (PDA, Notebook, ...) to synchronize files to another desktop PC.
Unlike many other synchronization software, DirSync Pro is Open Source; it is 100% free of charge, 100% free of commercial text, 100% free of advertisements and 100% free of spyware. You can use it as long as you like, without any limitations in time or funcationality. You can freely distribute it according to GPL3.
DirSync Pro is programmed completely in platform independent Java™ so it can be run under nearly every modern operating system including Windows™, Linux™ and Macintosh™.
DirSync Pro has a user-friendly User Interface which helps you configure many options to your needs. You can use DirSync Pro also through the command line which makes it very flexible for running in batches.

I was having a go at upgrading an XP virtual machine to Vista. During the exercise, I faced a number hard disk management issues. First, I needed to enlarge the virtual machine’s disk size as required by Vista. Once the disk was successfully enlarged, I then needed to extend the system partition before the Vista upgrade can proceed. After upgrade completes, I need to do shrink the virtual disk as it’s already quite large in size.
Allow me to first introduce two tools I used in the exercise. The first is the VMWare Disk Manager tool (vmware-vdiskmanager.exe). This virtual disk manager is included in the VMWare Server installation package.

In a shell script I wanted to take the execution time of a command and redirect it to a file. First I tried the following:
time command > time.txt
It didn't work. Then I found out that the time command prints its output to stderr. I changed the command to:
time command 2> time.txt
It didn't work either. The time's output was still printed on the console.
It turned out that time is a reserved word in bash. It's not like most of the builtin commands in bash but it's a true part of the command line syntax like 'if' or 'while'.
Redirecting the output of the bash time can be achieved by executing the whole command (including the time part) in a subshell as follows:(time command) 2> time.txt
Launching a subshell is not necessary. Redirecting output of a code block works as well.
{ time ls; } 2> time.txt
This will probably be more efficient that executing the external /usr/bin/time command . Also the bash time command may have some features you need. Or you want to rely on bash time because you don't know if the system installed time utility will have the features you need or not.
In redirection and pipe behaviour this is actually the equivavelnt of executing the external time command /usr/bin/time .
Suppressing the output from the command itself can be made by redirecting its standard output and standard error to /dev/null
{ time command > /dev/null 2>&1 ; } 2> time.txt

O ie7.js é um script muito útil e muito bom, desenvolvido nos últimos 4 anos por Dean Edwards, tem 31 kb e o grande desafio de consertar os bugs de renderização de html e css do ie 5.x e 6.
E o que ele faz realmente?
Adiciona novos seletores :
:hover
:first-child
:last-child
[attr]
[attr="value"]
[attr~="value"]
[attr|="value"]
[attr^="value"]
[attr$="value"]
[attr*="value"]
Altera as propriedades de CSS
background-attachment - > aceitando posicionamento fixo
background-image -> passando a aceitar png alpha
cursor -> ie IE5.x passa a suportar pointer
display -> converte list-item para block no IE5.x
margin -> suporta auto no ie 5.x
adiciona as propriedades max-height, max-width, min-height e min-width
Arruma até o HTML e corrige bugs como o famoso “Doubled Margin” (float: left; margin-left: 10px;)
A descrição completa do que o script faz, com exemplos, está aqui.
Como eu coloco isso no meu site?
Faça download do script clicando aqui.
Insira o seguinte código dentro da tag head:
Recomendo o uso desse script para backends, administrativos, pois normalmente para corrigir um bug, o script renderiza a página do jeito comum e só depois aplica o script e isso, nuUm site grande, pode ficar com o conteúdo “dançando” antes de ser completamente carregado.
Já tem uma versão para corrigir os bugs do ie7 também (ie8.js) e pode ser baixada no site do desenvolvedor.
Features:
$paginas = array(
"principal" =">" "/index.php",
"fotos" =">" "/fotos/index.php",
"contato" =">" "/contato/index.php");
Pronto. Agora existe dois jeitos de você usar a QUERY STRING, exemplos:
pagina.php?pagina="principal"
pagina.php?principal
1) Include($DOCUMENT_ROOT.$paginas[$pagina]);
2) Include($DOCUMENT_ROOT.$paginas[$QUERY_STRING]);
Você pode também checar se foi setada ou não uma QUERY STRING utilizando o método abaixo: if(empty($QUERY_STRING)) {
Veremos como fica este script completo:
include($DOCUMENT_ROOT.$paginas[principal]);
} else {
include($DOCUMENT_ROOT.$paginas[$pagina]);
}" "/index.php",
"fotos" =">" "/fotos/index.php",
"contato" =">" "/contato/index.php");
if(empty($QUERY_STRING)) {
include($DOCUMENT_ROOT.$paginas[principal]);
} else {
include($DOCUMENT_ROOT.$paginas[$pagina]);
}
?>
