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.

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

Simple Ways of Speeding Up Windows XP

I just finished setting up a new PC for a friend and I think some of you will be interested in some of the adjustments can I make all my computers to make them faster. I'm here focused on those that are simple to make and will not cause problems if you get ill, instead of registry settings etc. Quoting

1. Disable indexing services

Services Index is a bit small program that uses a large amount of RAM and can often make a computer endlessly loud and noisy. This process of system updates and lists of indexes all files on your computer. He does this so that when you do a search for something on your computer, it will look for faster scanning the index lists. If you do not search your computer frequently, or even if you do search often, this system service is completely unnecessary. To disable do the following:

* Go to Start
* Click Settings
* Click Control Panel
* Double-click Add / Remove Programs
* Click Add / Remove Window Components
* Clear the indexing service
* Click Next

2. Optimizing display settings

Windows XP can look sexy, but displaying all the visual elements can waste system resources. To optimize:

* Go to Start
* Click Settings
* Click Control Panel
* Click System
* Click the Advanced tab
* In the Performance tab, click Settings
* Leave only noted the following:

* Show shadows under menus
* Show shadows under mouse pointer
* Show translucent selection rectangle
* Use drop shadows for icon labels on the desktop
* Use visual styles on windows and buttons

3. Speedup folder browsing

You may have noticed that everytime you open my computer to browse folders that there is a slight delay. This is because Windows XP automatically searches for files and network printers everytime you open Windows Explorer. To correct this and to significantly increase navigation:

* Open My Computer
* Click on the Tools menu
* Click on the Folder Options
* Click the View tab.
* Clear the Automatically search for network folders and printers on the box
* Click Apply
* Click OK
* Reboot the computer
4. Disable Performance Counters

Windows XP has a performance monitor utility Monitors which several areas of your PC's performance. These utilities take up system resources so disabling is a good idea.

To disable:

* Download and install the Extensible Performance Counter List
* Then select each counter in turn in the 'Extensible performance counters' window and clear the' performance counters enabled 'below bottom.button checkbox at the

5. Improve Memory Usage

Cacheman Improves the performance of your computer by optimizing the disk cache, memory and a number of other settings.

Once installed:

* Go to Show Wizard and select All
* Run all the wizards by Selecting Next Finished or until you are back to the main menu. Use the defaults unless you know exactly what you are doing
* Exit and Save Cacheman
* Restart Windows

6. Optimizing your internet connection

There are lots of ways to do this but by far the easiest is to run TCP / IP Optimizer.

* Download and install
* Click the General Settings tab and select your Connection Speed (Kbps)
* Click Network Adapter and choose the interface you use to connect to the Internet
* Check Optimal Settings then Apply
* Reboot

7. Optimizing Your Pagefile

If you give your pagefile a fixed size it saves the operating system from Needing to resize the page file.

* Right click on My Computer and select Properties
* Select the Advanced tab
* Under Performance choose the Settings button
* Select the Advanced tab again and under Virtual Memory select Change
* Highlight the drive containing your page file and make the initial Size of the file the same as the Maximum Size of the file.

Windows XP sizes the page file to about 1.5X the current amount of physical memory by default. While this is good for systems with smaller amounts of memory (under 512MB) it is unlikely that a typical XP desktop system will ever need 1.5 X 512MB or more of virtual memory. If you have less than 512MB of memory, leave the page file at its default size. If you have 512 or more, change the ratio to 1:1 page file size to physical memory size.
8th Run BootVis - Improve Boot Times

BootVis will significantly improve boot times

* Download and Run
* Select Trace
* Select Next Boot and Driver Trace
* A Trace repetitions screen will appear, select OK and Reboot
* Upon reboot, BootVis will automatically start, analyze and log your system's boot process. When it's done, in the menu, go to Trace and select Optimize System
* Reboot.
When your machine has rebooted wait until you see the Optimizing System box appear. Be patient and wait for the process to complete


9th Remove the Desktop Picture

Your desktop background consumes a fair amount of memory and can slow the loading time of your system. Removing it will improve performance.

* Right click on desktop and select Properties
* Select the Desktop tab
* In the Background window select None
* Click OK


10th Remove Fonts for Speed

Fonts, especially TrueType fonts, use quite a bit of system resources. For optimal performance, trim your fonts down to just those that you need to use on a daily basis and fonts that applications may require.

* Open Control Panel
* Open Fonts folder
* Move fonts you do not need to a temporary directory (eg C: \ FONTBKUP?) Just in case you need or want to bring a few of them back. The more fonts you uninstall, the more system resources you will gain.
