Okay a short summary - I recommend reading the man-pages for detailed info.

nmap | netstat | socketstat

sudo netstat -tulpen | grep -v 127.0.0.1 -> View Services and Ports
sudo nmap -sS IP -> SYN-Stealth-Scan, view open ports
sudo nmap -sU IP -> Scan UDP Ports instead of TCP
sudo nmap -sV IP -> Scan for RPC and other Services
sudo nmap -A IP -> Includes sV and tries to detect the remote OS
sudo sockstat -lc -> Show open and connected Sockets

During the last days I wrote some shell scripts to keep my development environments in sync. When it came to arrays I experienced some weird problems.

fl0@fl0-m0thership:~/AutoPkgUpdater$ sh MakePlist.sh f00
MakePlist.sh: 25: Syntax error: "(" unexpected

Guess what's at line 25? Right, an array declaration...The weird thing: I was able to directly declare an array in the shell like the following:

fl0@fl0-m0thership:~/AutoPkgUpdater$ a=( one two three)

Sometimes you need to change the default Python version of your OS.
For Ubuntu you can accomplish that by editing the "debian_defaults" file.
1. Go to:

$ cd /usr/share/python
$ sudo nano debian_defaults

2. Change the version as needed:

To make your touchpad behave pretty much like under OSX just create a new file /etc/hal/fdi/policy/appletouch.fdi with the following content:

<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
  <device>
    <match key="info.capabilities" contains="input.touchpad">
      <match key="info.product" contains="appletouch">
        <merge key="input.x11_driver" type="string">synaptics</merge>
        <merge key="input.x11_options.VertTwoFingerScroll" type="string">1</merge>
        <merge key="input.x11_options.HorizTwoFingerScroll" type="string">1</merge>
        <merge key="input.x11_options.TapButton1" type="string">1</merge>
        <merge key="input.x11_options.TapButton2" type="string">3</merge>
        <merge key="input.x11_options.TapButton3" type="string">2</merge>
        <merge key="input.x11_options.FingerLow" type="string">10</merge>
        <merge key="input.x11_options.FingerHigh" type="string">20</merge>
        <merge key="input.x11_options.PressureMotionMinZ" type="string">10</merge>
      </match>
    </match>
  </device>
</deviceinfo>

"Woooow - this is awesome!" You'll need 3D glasses to get the effect...This video shows a 3D Stereo Ubuntu (compiz enabled)! To watch the HD Version visit the link below the vid

A series of screenshots showing the effect:

During the last few weeks I was recapitulating my prior projects concering Human Computer Interfaces...All of them, namely T.I.R.E.X & the Pad, dealt with three dimensional display characteristics. But why? Since "3D" is obviously a part of our "real life" some applications like CAD programms or the simulation of e.g. car crashes or robots are "naturally" implemented in 3D space.

If you've ever looked at a CAD prog. or an OpenGL simulation the physics are great, the lightning is great, you can rotate, transform and project things. BUT - the display is still 2D in the end. Sure - all the stuff desribed above helps you to get the impression of a "real" 3D model but you still ned a tiny little bit of imagination. I would like to increase this little "bit" and present you an easy way to implement and use the power of OpenGL and anaglyphic stereoscopy.

What is anaglyph?
