Expose stop working after connecting to external monitor

When ever I unplug my MacBook from an external monitor, Expose stops working. The solution to this problem is to kill "Dock" application.  To make it easier, I have created a script which allows you to do the same.

set app_name to "/System/Library/CoreServices/Dock.app/Contents/MacOS/Dock"
set the_pid to (do shell script "ps ax | grep " & (quoted form of app_name) & " | grep -v grep | awk '{print $1}'")
display dialog "Killingn the application Dock with PID:" & the_pid
if the_pid is not "" then do shell script ("kill -9 " & the_pid)

Copy following lines of code into text editor and copy under $HOME/Library/Scripts/killdock.scpt.  Now you can see the script listed under scripts as an shortcut. You can see "kill dock" listed at the end.

Does Internet Speed check varies based on the browser

I wanted to see whether browser makes different while checking the speed of the internet.  I did  speed check test using speedtest.net  and four different browser and surprisingly all of them gave different results.

1: Safari  Version 4.0.3 (5531.9)
Download Speed: 17.16 Mb/s
Upload speed: 4.08 Mb/s

2. Firefox Version 3.6 (rv:1.9.2 Gecko 20100105)
Download Speed:15.84 Mb/s
Upload Speed:4.25 Mb/s

3. Chrome Version 4.0.246.0 (31780)
Download Speed:15.47 Mb/s
Upload Speed:2.17 Mb/s

4. Chrome Version 4.0.249.43:
Download speed: 17.65 Mb/s
Upload speed: 3.98 Mb/s

Looking at the results, it seems speeds varies based on the browser. You can see latest version of the Google Chrome has improves and you can see both the upload and download speed has increased.
