A good explanation about setting up SPF-records for domains can be found here:
To have scripted automated backup of PostgreSQL databases on a linux platform, you can create a script like so:
#!/bin/bash PGPASSWORD="your-password" /usr/bin/pg_dump -U user database > sql-file.sql
Replace user and your-password with your username and password; replace database with the database you want to backup. The output of the dump goes to stdout and can be piped to a plain text file or compressed to something else.
A plugin for Thunderbird exists for easy import and export of mails in all sorts of formats. It is available for all platforms and can be downloaded here:
One of the features is the ability to import entire folders and subfolders containing mails in .eml format.
There will be some maintenance going on today and tomorrow, each time at night. During that time, our website might not be accessible.
It is possible to have multiple iPhoto libraries, and not just one. To create a new library, hold down the Option (⌥) key while starting iPhoto. This will prompt you to create a new library or open an existing one.
Alternatively, you can also use iPhoto Buddy, which allows you to easily select libraries from a nice GUI.

Currently, the official Avast for Mac Edition available for download is still at version 2.74, released somewhere in 2007.
This version still has many annoyances and bugs that have not yet been resolved (one of these issues is the ability to run automatically in the background, without the main window popping up at start up each time).
Luckily, the Avast Forum has a post, providing a new release candidate is available for download for some time now. The build is also a bit outdated but has at least many fixes that aren't present in the official release.
The direct download link is: http://public.avast.com/~cimbal/avast.3.11.zip.
With the take-over of Sun by Oracle, they have been seriously rebranding just about everything there is to rebrand: Java, Virtualbox, OpenOffice, MySQL, ...
I noticed this in the About box of OpenOffice 3.3:
This is pretty much the result of what happens when a major company is on a buying spree to acquire technology from various other companies, and leaving a lot of the community developers seamlingly standing in the cold (although there's a small footnote mentioning their contributions).
Everything you need to set up and use VDI for free...
That's what Citrix is providing nowadays with XenDesktop Express. It provides full VDI for up to 10 users, and can work with XenServer, Hyper-V and VMware.
The full link to everything is this one:

Something to remember: escaping entities (e.g. when you have table or field names that are the same as reserved words) is possible using square brackets
Some examples:
CREATE TABLE [User] ... SELECT * FROM [User]
I had to use this while renaming logical names, which had a dot in their name.
In VMware ESXi 4.1, by default, the video drivers are not correctly installed. This is because of the fact that the old driver (which is installed by default) is a WDM type of driver. This type of driver has been kicked out of Windows 7 and Windows 2008R2 in favour of the newer WDDM driver architecture. As a result, the video is reverted to the Standard VGA adapter, which has terrible performance.
However, installing the VMware Tools does provide a correct driver, even though it is not installed by default. To install it, see the second chapter of the article: Windows 2008 R2 console freezes in vSphere console.
