Twitter Version 2.0.10(2010)

Twitter has unveiled its new version( say version 2.010) that changes the interface, introduces new features and promises to be "faster, easier and richer." This will have a double-paned view of things. Quite frankly, it uses a lot of the wasted space on the page.

Each pane will take up half the screen. The left-hand column will contain the regular old timeline of Tweets. Click on a Tweet, and the right hand pane shows the details of the Tweet, including the user profile of the sender, the conversation it's in, and more. Videos and pictures can be seen in the right pane.

Some of the welcomed features of this new twitter are as follows:
  1. Two-pane interface:
    The new interface is clean and well organized. Lists and trends are easier to view (requiring less scrolling) than with the old Twitter.
  2. Embedded media:
    New Twitter will display the photo on the right half of the page . You'll also see more information such as other tweets that have linked to that same image. Videos, too, will be embedded. If you click on a tweet containing a link to a YouTube video, the video will play right on right-hand pane instead of redirecting you to YouTube. This eliminates the hassle of closing multiple browser tabs once you're done viewing. 
  3. Continuous scrolling:
    In the new Twitter, the "more" button at the bottom of the page used to load older tweets will be gone. Now, you'll be able to scroll through older tweets continuously, without having to manually load more.

Automatic wallpaper changer script for Linux

I always want linux to compete with windows. In windows 7 , wallpaper changes automatically .So i wrote this script .


# please report bugs to the author

# Usually the background pics are stored in /usr/share/backgrounds

cd /usr/share/backgrounds

num=`ls | wc -l`
#echo $num
choice=`expr $RANDOM % $num`
#echo "choice is $choice"
filename=`eval ls | head -$choice  | tail -1`
#echo "That is $filename"

if [ -f $filename ]
gconftool-2  --type string  --set /desktop/gnome/background/picture_filename "/usr/share/backgrounds/$filename"
  #echo "$filename is not a file"

Downloading youtube videos

There are lot of ways you can download youtube videos.I will mention a few online downloaders..
Different methods are here:
  1.   Replace youtube in the URL by voobys
     If the url of the video is ,change it to , You can download the video from this link.

   2) Add "kiss" to the youtube URL
         So change the above url as
   3) Add ok to the URL
           Change url as

  4) Some other webpages where you can download youtube videos:
  5) For those who prefer command line terminal , use Youtube-dl package . You can then  download the video by typing   youtube-dl 
But remember downloading vids is forbidden by the Terms of Service of youtube and in some cases illegal.You can watch them on YouTube and you can, providing the video owner lets you, "embed" them to other sites using the code beside the video you want to show off elsewhere.  And you can use the email function to send them to people who you want to show it to.
All that is done on YouTube, directly on the video's page itself.  :)

For my last post on an interview test , i came accross a situation to show a less than symbol near character 'b' like < b (without spaces).But blogger misinterpret me and the post was made bold.Then i tried giving the standard HTML symbol for less-than < , but of no use. So from a google search i found this solution. You can give & # 60 (without spaces.I gave spaces to show you ). That works ..

Amazon Interview questions

I recently had an interview for internship by Amazon . Here i'm posting the questions asked during that . There were about four questions , out of which one was coding .

1) Consider you have a list of 2n+1 elements. n elements in the list have one duplicate. Give the algo to find the remaining unique element(the element without duplicate) ? { Eg: array 5 2 4 4 2 1 5 : here 1 is the unique element }

Modify the algo , if we have many elements without duplicate ? { Eg: array 5 2 4 4 1 7 2 3 5 here 1 7 and 3 are unique ie without duplicates }

2) Consider a singly linked (non circular ) list . Give the algo to find the pointer to the k'th element from the last , in a single iteration through the list .

3) Consider you have an array . the elements are arranged as in increasing order till a peak element , and from this element onwards it decreases..Give the algo to find this peak element .{ Eg: array : 2 3 4 5 6 3 2 1 : here 6 is the peak element. }
Modify your algo to take care of multiple peak elements . { Eg: array 2 3 4 5 6 3 2 1 5 8 9 2 1 here we peak elements are 6 9

Coding :
Write a definiton for the function with prototype given below:
Reversal(pointer to head of list, an integer k )
This function takes a list and an integer k, and reverses the first k elements of list and return a pointer to the head of new reversed list .
