Google Mail is More Secure than Ever

Well friends, when we use the INTERNET do we really wonder how much of our information is being leaked to the world with or without our knowledge.Not really but it also affects our privacy especially if privacy and secureness is one of ur need for sending information.Google recently intoduced the use of HTTPS which is the secured version of http protocol , n perhaps its make use of IPSEC, KEBEROS And SSL.HOwever one downside of security is that it reduces performance as you may have noticed.To access ur inbox using secure version use can use:

https://mail.google.com

or

enable it by default

You can even disable it but beware it will make ur connection slower due to encrytion and decryption , but ita up to u to choose security or performance.

Sexondly google introduce a new feature where u can have a log of activities to ur emai l and this might be useful  wen u 4got to signout ur email at another place u can even see where it was and hence take due action .wow here r screen shots.

Itis found at the bottom of your inbox, and by clicking on more details you get ..

GOOGLE KNOL

wow what  an exciting feature google has lauched called KNOL , wich is a community abt sharing thing s ur know and also respect the copyright , here is the link i discovered and hpe u will enjoy them,http://knol.google.com, woow google R0Cks!

2day Im going to The Orange P@rty at UOM

Wow, only 1 year left to finish university course so ot 2 enjoy a bit too , so going to the party 2nite. will keep in touch

Postgresql Codes to add in an array

  create or replace function AddArray(integer [],integer[])returns integer[]) as '
declare

                  a alias for $1;
                  b alias for $2;
                  c integer [];

             begin
                 c:=''{}'';
                    for i in 1..5 loop

                       c[i]:=a[i]+b[i];

                    end loop;

                    return c;

  end;
' language plpgsql;

A very nice place for tutorial :

Special thanks for all thse codes published goes to sydney,kooshal, yannick, vanessen and vikesh and all those who contributed .

using structures loops etc

Write a program that performs the following:
It creates an array of a structure student (What the structure contains is your choice).
It executes a loop that displays a menu as follows:
1.Add new student
2.Modify a student information
3.Display Array
4.Exit
It allows the user to choose one of the above menu options.
If the user chooses option 1, the program allows the input of the student information, builds a structure, create a thread passing the created structure as argument. The thread simply adds the structure to the array.
If the user chooses option 2, the program allows the entry of a key (such as student id), creates a thread passing the key as argument. The thread requests for the field to be modified and the new value and makes the required modification.
If the user chooses option 3, the program creates a thread that displays all filled elements of the array.

In each of the above cases the thread exits after having performed its task.
