Set up wireless without KDE nor Gnome

One of the first problem faced when going away from KDE, Gnome or XFCE is that you have to set up your wireless connection manually.
If you have 10 minutes, it can be done once and for all: just follow this how to HOWTO: Wireless Security - WPA1, WPA2, LEAP, etc..
Then you can remove the NetworkManager startup script : "sudo update-rc.d -f NetworkManager remove".
Keep in mind to launch a "sudo /etc/init.d/networking restart" in case of problem.

Update: I just found a solution to automatically start Network Monitor Applet (nm-applet) with Awesome Window Manager. But I am quite happy with my current setting, it just connect when it starts.

VirtualBox, CentOS, Network and Template

I have been working with VirtualBox and CentOS recently, here are some notes about this experience.
I used VirtualBox 4.2 and CentOS 6.3, but most of this should work with other products too. I created the first headless, minimal CentOS via NetInstall.
I cover two points: create a template machine and configure the Network.
Configure the NetworkWe want Internet access and a LAN local to the host.
For background information read: Networking in VirtualBox by Fat Bloke on June 2012.
The easiest is to enable two Network Adapters: One will be "Host-only" and the second "Nat". In the "Preference" menu you can see the DHCP server range for the Host-only Network. So you may set fixed addresses outside this range.
Next: start the guest. There may be various results at first, depending on a lot of things. Some problem might be solved by rm -f /etc/udev/rules.d/70-persistent-net.rules and a reboot.
Anyway, configure the two interfaces (set your own IP and MAC addresses)…

One in six IT projects ends up ‘out of control’

http://www.ox.ac.uk/media/news_stories/2011/110822_1.html

A surprisingly high number of projects are 'ticking time bombs', according to researchers at the University of Oxford. They analysed 1,500 global projects that had revamped their information technology systems within the last 10 years. They discovered that one in six projects in the sample went over budget by an average of 200 per cent (in real terms) or over ran by an average of almost 70 per cent.

Their conclusion is similar to previous studies: http://brunovernay.blogspot.com/2009/10/excellent-studies-on-software-quality.html
