iTune installation failure on Vista

Today, I received my iTouch, and as I tried installing iTune from Apple, I could not believe when the installation failed. I tried again, and it failed again. It kept on happening for some more tries (between the multiple reboots I did). But it did not installed on my Lenovo having Vista Home Premium. As I double click on 70 MB+ files I downloaded freom Apple's website, a DOS window disappears as soon as it appears. I am at my wits ends!!! I have been able to install softwares of my choice on this laptop, and never before, had a problem. I think there are many many Vista users who are having the trouble with new version of iTune. Help me if you know the problem and the solution. Meanwhile, I am downloading the previous version of iTune for installation.

[Update] - Installation of iTune 7.7 was successful; however, when I connected my iTouch, it refused to work with it, saying v8 or later is required! I then updated iTune from its Help menu option. The update was of 85 MB, and it went well. I connected my iTouch, and it immediately recognized it. No problems faced this time!

How Google Is Showing Off Chrome

The Google home page has been ransacked. The familiar, colorful logo is upside down. The search box and the "I'm Feeling Lucky" tab have been uprooted and now point up at a rakish angle, jutting into white space. Other links have tumbled from the top navigation bar and lie in a heap on the side of the browser. What on earth is going on? Have the hackers taken over?

The screwy design is part of a new series, Chrome Experiments, that Google is launching on Mar. 18 to demonstrate the potential of Chrome.
The jumbled home page is actually a program called Google Gravity. British interactive design firm Hi-Res! recreated the search giant's regular home page, giving users the ability to wreck the joint. With the mouse, a user can spin the traditional elements into space. They soar, they careen, they bounce, until they settle higgledy-piggledy at the bottom of the browser window.

In Windows Vista, if for whatever reason the drive letter or paths assignment to a disk-drive, CD/DVD drive, USB flash memory disk drive, or external hard disk drive needed to be changed or modified, users can use Disk Management console to manage the volumes and drives on the computer, including changing the drive letter and paths.

And if you install some applications or programs in the drive that you have just changed the drive letter, they may not functioning properly after the change due to the possibilities that the programs will also refer to the specific drive letter or original path used when installation as environmental variables.

Copy/Paste the block of text in vi/vim

  • Mark the location of the first character of the block of text you want to copy by pressing mx
  • This marks the begining of the text to be copied into a buffer 'x'.
  • Move the cursor over the last character of the block of text you want to copy and press (shift)+x
  • By pressing shift you are moving all the characters from mark to the current position into a buffer.
  • To copy (or, in vi terminology, to yank the buffered text) press y'x
  • This will yank everything from the buffer x. ('tick' character ' is command in vi to read from the named buffer)
  • Now move the cursor above the location where you want to paste the yanked text and press p
  • p (for paste) will insert the copied (yanked) text at the line below the cursor.
