Autoplay is also known as Autorun which should already be disabled for your cd-rom drives because of companies like Sony who like to install DRM on your computer without even asking you. There is a good article from Engadget on how to disable Autorun using a .reg file. This only works for CD-ROM drives and does not disable Autorun for USB drives.
There has been recent news of people gaining access to machines on an internal network using social engineering and USB drives. This guide will show you how to make sure that Autoplay/Autorun is disabled for all devices on your computer. It is highly recommended that you make sure Autorun is disabled for any computers you have access to at work that are running Windows XP. Disabling just the CDROM for your home computers is probably good enough since physical access to those computers is more restricted.
1. Click Start > Run
2. Type “gpedit.msc”
3. Computer Configuration > Click “Administrative Templates” > Click “System” > Double-Click “Turn off Autoplay”
4. Setting tab > Check “Enabled” > Select “All drives” from the drop down menu > Apply > Ok
disable-autoplay
There 4 easy steps to making sure that Autoplay (Autorun) is disabled on all your drives including the USB. That would remove the ability of people to insert a USB drive and automatically run a .exe on your computer by using a *.inf file.
The last thing that you can do to protect yourself is to make sure that you have “Hide extensions for known file types”. This will help you from accidentally clicking on a file that is on a USB drive that looks like it is safe to look at, but is not really. This is one aspect of social engineering that is dependent on the user to make the right decision.
Many criminals will try to mask the presence of a malicious file by adding on .exe to the end of a common file type. For instance .doc.exe or .xls.exe or .jpg.exe would be some examples. The file that you click on is not what you expect it to be rather a virus or a program used to compromise your system. Most anti-virus programs will catch this file after you execute it, but to be on the safe side it is best not to click on it in the first place.
- Open a local folder in Windows Explorer (not IE) like My Documents > Click Tools > Click Folder Options > Click “View” Tab > Uncheck “Hide extensions for known file types”

Update
I updated some of the links that didn’t work, like the link to the news article about the Sony DRM and the old .reg file. I found a copy of the reg file somewhere else on the internet and rehosted it here so it doesn’t disappear again.

How to check if someone has blocked you on Google Talk
There is a great little instant messaging utility, Pidgin that helps
to find who has blocked you in Google Talk. If you not sure how to
configure Pidgin with Google Talk, I advice you to first visit this
page.
Ok, now when you are aware of how to configure Pidgin to work with
Google Talk, I'll guide how to make smart use of Pidgin to identify
who has blocked you on Google Talk.
It's very simple. Just follow the steps:-
1- Log in to your Gmail account on Pidgin.
2- Go to "Buddies" -> "Show Offline Buddies". (A person who has
blocked you must be showing offline to you. So you need to make all
offline friends visible)
3- Now all your contacts are visible to you. Pick any one of those.
4- Right Click on your chosen contact name and select "Get Info".
It will show you the brief information of your contact. Now, if any of
your contact has blocked you on Google Talk, you will not be able to
see his/her profile.
6- Select a contact who you think may have blocked you. Again, Right
Click on his/her name and select "Get Info". You will not see
anything. Not even the contact's name.
This goes to show that this particular contact has blocked you on
Google Talk and don't want to talk to you and so it appears to be
offline always.
Hope, you like this article. This is the only way I could able to find
out to determine who has blocked you on Google Talk. What's your
comment on this?

Difference between CGPA and SGPA?
CGPA is the cumalative grade point average and
SGPA is semester grade point average.
Grade point is a system in which points are given between 0.00 to maximum of 4.00 depending upon the grade obtained in a particular course.
SGPA is the average of grade point obtained in a single semester while
CGPA is the average of grade point obtained as whole.
SGPA is semester grade point average.
Grade point is a system in which points are given between 0.00 to maximum of 4.00 depending upon the grade obtained in a particular course.
SGPA is the average of grade point obtained in a single semester while
CGPA is the average of grade point obtained as whole.
CALCULATE CGPA
Calculating your CGPA/SGPA is not an uphill task, it requires little smart work. First you need to know the number periods per week of each subject .After that you will calculate the credits of each subject. Say in first you have 7 subjects :
*Physics: 3 lectures 1 tutorial
*Chemistry: 3 lectures 1 tutorial
*Math: 3 lectures 2 tutorials
*ECO: 3 lectures 1tutorial
*ELECTRICAL :2 lectures 1 tutorial
*Basic Electronics: 2 lectures 1 tutorial
*Engineering Drawing :3 classes
*Physics PRAC: 2 Classes
*Chemistry PRAC: 2 Classes
*Basic ELECTRICAL PRAC:2 Classes
Now each lecture has one credit and each prac or tutorial has 0.5 credit. So , in the above case
Physics,Chemistry,ECO has 3.5 credit each;
Math has 4 credit ;
Basic ELECTRICAL, Basic Electronics has 2.5 credit.
All practical have 1 credit.
Engineering Drawing has 1.5 because its classes are not considered as lectures but they are treated as tutorials.
This was all about calculating credits.
In each subject you get some grade, which you get according to your marks ,they have been given in below .Points have been allotted to each grade.
A+(85&above) ---------- 10
A(75-84) ---------- 9
B (65-74) ----------- 8
C (50-64) ---------- 6
D (40-49) ---------- 4
E (39 & below) ------ 2
If you get E grade you don’t pass the course,you will have to appear again in that course.
So your SGPA that is your grade point aggregate for semester is calculated as follow:
SGPA=∑{credit of subjectn*points u get in subject n}/total credits
CGPA=∑{credit of semester*SGPA of semester}/total credits so far
*Physics: 3 lectures 1 tutorial
*Chemistry: 3 lectures 1 tutorial
*Math: 3 lectures 2 tutorials
*ECO: 3 lectures 1tutorial
*ELECTRICAL :2 lectures 1 tutorial
*Basic Electronics: 2 lectures 1 tutorial
*Engineering Drawing :3 classes
*Physics PRAC: 2 Classes
*Chemistry PRAC: 2 Classes
*Basic ELECTRICAL PRAC:2 Classes
Now each lecture has one credit and each prac or tutorial has 0.5 credit. So , in the above case
Physics,Chemistry,ECO has 3.5 credit each;
Math has 4 credit ;
Basic ELECTRICAL, Basic Electronics has 2.5 credit.
All practical have 1 credit.
Engineering Drawing has 1.5 because its classes are not considered as lectures but they are treated as tutorials.
This was all about calculating credits.

B (65-74) ----------- 8
C (50-64) ---------- 6
D (40-49) ---------- 4
E (39 & below) ------ 2
If you get E grade you don’t pass the course,you will have to appear again in that course.
So your SGPA that is your grade point aggregate for semester is calculated as follow:
SGPA=∑{credit of subjectn*points u get in subject n}/total credits
CGPA=∑{credit of semester*SGPA of semester}/total credits so far
