Throw away your TV

I recently came across this site called "Throw away your TV". It has tons of funny videos as well as educational ones.

One feature I liked was, when I am watching something, if I go to a different browser tab, it actually detects it and stops playing the video, only to continue after I go back to it.

AutoIt Automation Tool

In the previous article about lost USB devices, author talks about AutoIt. I checked it out and it seems like a nice automation tool for Windows that can . There is also an informative Wikipedia article about it.

Below is from their home page:

AutoIt v3 is a freeware BASIC-like scripting language designed for automating the Windows GUI and general scripting. It uses a combination of simulated keystrokes, mouse movement and window/control manipulation in order to automate tasks in a way not possible or reliable with other languages (e.g. VBScript and SendKeys).

AutoIt is also very small, self-contained and will run on 95, 98, ME, NT4, 2000, XP, 2003 out of the box with no annoying "runtimes" required! You can even make compiled executable scripts that can run without AutoIt being installed!

Accessing Ubuntu from Windows with FreeNX

[ORIGINAL POST - 06/02/2006]
My coworker, Andy Mei mentioned FreeNX to me. I checked out the Ubuntu Forums on FreeNX and FreeNX Wiki page. It's a two-part (client/server) software...

To install FreeNX on my ubuntu dapper,

First I added the following line to my /etc/apt/sources.list:
deb dapper-seveas freenx
you can try other repositories.

If you do not want to get gpg errors, import them:
  • sudo gpg --keyserver --recv-keys 1135D466
  • sudo gpg --export --armor 1135D466 | sudo apt-key add -
Then I,
  • fired up Snaptic Package Manager,
  • clicked reload to get updared package list from the newly added repository
  • then searched for freenx
  • marked it and clicked apply
To make installation simple, I did not enable ssh. Then, I went to NoMachine's website & downloaded NX Windows Client.

Result is a very fast & easy connection from Windows XP to Ubuntu Linux (see screenshot above).

Ahh, don't try to be smart and install it from cmd line `sudo apt-get install freenx`. I know people who did and suffered ;-)

[UPDATE - 09/29/2006]
OK, I take that back! I now have a beta version of Ubuntu Edgy Eft (Knot 3) running on my linux box and I installed it from command line:
sudo apt-get install freenx
I chose No machine keys during the set up and it works just fine!

[UPDATE - 10/02/2006]
I downloaded the new NxClient (2.1.0-6) from It failed to connect to my Ubuntu
NX> 704 Session cache: unix-gnome
NX> 707 SSL tunneling: 0
/usr/lib/nx/nxserver: line 891: 27507 Terminated              
( sleep $AGENT_STARTUP_TIMEOUT; exit 1 )
NX> 105 NX> 504 Session startup failed.
NX> 1004 Error: nxagent failed to start with: Unrecognized option: 1
NX> 1001 Bye.
Apparently, it needs a compatible client/server installation...

Useful Free Windows Programs Under 2MB

Over 20 free windows applications under 2mb, courteously of revision3 forum member, lordfoul. Definately a list to look into. Applications range from miscellaneous software, command utilities, system performance tools, and more.

- Taskbar Shuffle (left-click and drag the programs/buttons on your Windows taskbar to rearrange them)

- Power Menu (adds "Always On Top", "Minimize To Tray", "Priority" and "Transparency" sub menus to all top level system menus)
