Selection Sort Vs Insertion Sort

Selection Sort: Given a list, take the current element and exchange it with the smallest element on the right hand side of the current element.
Insertion Sort: Given a list, take the current element and insert it at the appropriate position of the list, adjusting the list every time you insert. It is similar to arranging the cards in a Card game.
Time Complexity of selection sort is always n(n - 1)/2, whereas insertion sort has better time complexity as its worst case complexity is n(n - 1)/2. Generally it will take lesser or equal comparisons then n(n - 1)/2.
Any suggestion to improve this article is always welcome!

Quickly ping Google/Yahoo to know your Connection Status.

1. Open notepad and jot down ping -t 209.85.171.100. Close and rename it as *.bat file. This is the IP address* of Google.

2. Send shortcut to your Desktop.Change icon(Optional).

1. 2.

Note: Don’t use IP address of Microsoft.com/Amazon.com, etc as they don’t respond to ping command.

For my broadband connection ‘Round Trip Propagation time’ of around 300-400ms(seen in snapshot above) indicates a fairly good connection speed. If you see reply from remote server, close the batch process.

*why use IP address? If the connection is not ok, the batch process will fail to execute if you simply write ping -t google.com, so you won’t be able to find the problem.

ADSL Splitter Connection.

Last night I shifted my modem and laptop to another place, so I had to disconnect all the phone and modem connections. After reconnecting my router ‘line state’ was showing ‘Down’ rather than ‘Showtime’.

I tried to figure out the problem but was unable to do so. In the morning after much of the troubleshooting I finally figured out that the problem was with the splitter connection. Damn!!!

I have interchanged the modem and phone lines while reconnecting… what the hell?

 

Ubuntu 8.1 delivered.
