By Ralf Hildebrandt and Patrick Koetter on Tue, 2006-11-21 19:48. Software
Developed with security and speed in mind, Postfix has become a popular alternative to Sendmail. The Book of Postfix published by No Starch Press is a complete guide to Postfix whether used by the home user, as a mailrelay or virus scanning gateway, or as a company mailserver. Practical examples show how to deal with daily challenges like protecting mail users from SPAM and viruses, managing multiple domains, and offering roaming access.

AJAX Magazine: Howto integrate Google Calendar in your website using AJAX: "Howto integrate Google Calendar in your website using AJAX

One of the features I find it interesting in Google calendar is the possibility to create shared calendars, but also the availability of your calendar as XML or ICAL whatever it's a private or public one. As soon as we have XML of our calendar available I was wondering why not integrating Google calendar directly in website. For example a community that use the service to manage their events, or to display your future trips in your blog ?"

Criando, Copiando e restaurando imagens de HD com o Ghost for Unix (g4u): "Criando, Copiando e restaurando imagens de HD com o Ghost for Unix (g4u)

Como todo administrador de rede gosta e precisa, nada melhor do que ter uma imagem pronta dos computadores de sua rede, com tudo configurado. A reinstalação fica muito prática assim.

A ferramenta que tenho usado no meu trabalho é a g4u. Embora o nome seja Ghost For Unix, ele tem suporte a clonagem com sucesso de vários sistemas operacioanais, como: NetBSD, Linux, Novell Netware 4.11 and 5.1, Solaris/x86, Windows NT, 2000 and XP. Aqui no meu trabalho faço a clonagem de Linux e Windows XP sem problemas.

Agora vem o melhor de tudo. Para quem usa Linux com dual boot (ou mesmo quem não usa), ao fazer o clone (ou imagem) de um HD, ele copia a MBR junto. Achei essa facilidade algo maravilhoso."
