OpenSource software should be encouraged more…
There are times when it is easier to change a setting through a GUI rather than the command line. You can launch a remote GUI application on your local machine through SSH.
Both machines need to be Linux with a desktop environment installed. I have tested this with two Ubuntu 10.04 systems.
Sometimes you have to load a logical volume that is not part of the main filesystem. Other times you might have to mount a volume from a live CD, perhaps to recover data from a system that is no longer booting.
In both cases it needs to be done manually.

Netbeans 7 is out. I have been using it for PHP, at work as well as at home, for almost two years and I have to say it has become by far my favourite PHP IDE.
The Netbeans IDE started in 1996 for Java. PHP support came with version 6.5 in late 2008. Since then, every release has improved significant[……]
By default, most Linux systems deliver system emails — cron output, monitoring alerts, security notices — to the local root mailbox. If you never check it, those messages pile up and you might miss something important.
The simplest way to deal with this is to forward them to an external address. The[……]
When you install MediaWiki, new user registration is enabled by default. Anyone can create an account and start editing. That’s fine for a public wiki, but not always what you want — especially for a private or company wiki where you want to control who has access.

Sometimes I need to test the email functionality of a PHP website on my local machine. The best and easiest way I found so far is using sendmail as a smart host.
A smart host is a piece of software that routes email to an intermediate mail server rather than directly to the recipient’s server[……]
Do you often have the need, or want the pleasure, to try a new operating system?
Do you prefer using a “real machine” rather than creating a virtual one (like VMware or Virtualbox for instance)?
Have you got a spare machine for this purpose?
Ok, if you responded “Yes” to all the above, please rea[……]
If you connect to a remote server regularly, typing your password every time gets old fast. Key-based authentication is the standard way around this — it is more secure and more convenient once set up.
On your local machine, run:
ssh-keygen -t rsa
This creates a 2048-bit RSA ke[……]
A child theme lets you customise an existing WordPress theme without losing your changes when the parent theme updates. Every time the parent theme is updated, any files you edited directly get overwritten. A child theme avoids this.
Start by creating a folder and a style.css file that declares the[……]
If you have more than one network card (wireless and ethernet, like in a normal laptop) you can share your Internet connection with another computer via the ethernet cable. “When should I need such a thing?” you say. I know, I know… let me explain. :-)
