Have you ever thought if the person that you always move with is your real friend?

People do find it difficult to judge friendship.

Take this experience i had today. At a lecture the whole class was in jolly good mood. Pretty obviuos cao it was the last week of the semester and thus the very last class.

A friend of mine hit me in my back for fun and then a friend sitting in front of me commented on that. And to that comment i said something which was meant to be a joke. But well, did that person take it seriously. In fact a friendly banter changed in to that person saying some harsh things to me. Anyways it ended with hurt feelings for both parties.

Now here is the point, if that person was a real friend , he/she wud have understood that i meant it to be joke and did not mean any harm. And thus not made it look like a offense and retribute. Now a real friend will forgive you for small mistakes that you do and help you to be a good and better person. A real friend wil understand ur feeling and thus always try to be sensitive.
Real friend will not think about the getting help from the other but about helping him with no intention of returning the favour! The point was this, assuming i did say something inappropraite the friend should have understood that i meant no harm. If that person doesnt understand no give any slack to you when making mistakes that person is not a good friend! We all do make mistakes at one time or another, so if your so called friend doesn't forgive you then he is faking friendship till he gets his job done by you! beware of these people they are real danger!
infact those a real leachers who will smile a appear friendly only till they get their thing done by you and afterwards smailes and words will be gone!!!!!

A real friend will open his heart to your feelings and help make smoothen the rough edges of life.

Being real friend is truly difficult coz it is about giving love selflessly. But try to be a better friend every day, so that one day you can end up being a beautiful person in your heart a true friend!

cheers in your path towards building true friendshipsQ

real speed of the SLT ADSL home connection

512kbps upload 128kbps download unlimited SLT home ADSL package speed results.


I have now used slt adsl home package for 1.5 yrs . The cost including taxes is SLR 1850/= inc. taxes .

I have found it to be very reliable and within the 90% speed limit of which it was quoted.
Using IDM i get 55-60KBps download speed and good seeded torrents gives a speed of ~50KBps.

The service of SLT in this section is good too.

As this is unlimited download connection , i have downloaded lots of torrent and big direct downloads. Even then there have being no throttling of bandwidth and i get 60 out of the theoretical 63KBps.

Relay grading tutorial

This is a brief glimpse into the relay grading tutorial we had for our level 4 sem1 protection subject,

Orion in the sky

About a year ago my eyesight dropped rapidly , i coudnt even find the constellations in the sky. But today peeking from the balcony i saw my favorite "ORION" the hunter in the sky. The ancient Greek mythologies that i read in my childhood made me a dreamer and a romantic. I still do dream a lot.
Orion was a major reason of me doing so. Seeing Orion today makes me feel my old confident self again. I did lose my confidence about a year ago when i screwed my studies big time in level 3.
But things have being great lately and i feel my spirit heart and brains have returned. i am pumped up and ready to charge and do what i want, the way i want and be the best hasala ever!

Funny how seeing a simple thing as a constellation in the sky made me soo happy !

Life is awesome :) :) :)

Life is awesome

These days have been actioned packed for me with the beat even faster than 24.

A mess in the uni, a bigger mess and fight in front of our house, extreme efficient studying, Working out in the park every day and hanging out with my friends all contributed to this.

Well i need to be frank when i say that fights motivate me. The lethargic pace of life turns to a much more motivated lively pace.
Didn't go for karate as grading test was scheduled for this saturday.
Feel extremely fit and ready to go the final lap of the first semester!

Sweetest victory!

Life is a fight

After a long lull my life entered another phase. The transition is from peace to war. From sleeper to fighter. This is about survival and not about victory. The experience is bitter but refreshing. Getting into a fight motivates me to do my best. And when i feel safe the motivation seeps from me and i become another ordinary guy. But when there is some rivalry and enemies, in the face of adversity i become a completely different person with a drive like no other.

Numerical differentiation

We did a practical to find the knee point voltage of a CT.
We got 6 readings and from that we are to draw a graph and find the knee point voltage which is the voltage at which the gradient of the tangent becomes 0.2.

After drawing the graph saw that the knee point lies above the range of readings taken so tried out a numerical method instead of a graphical one.

1) Interpolate and extrapolate the values to suffiecient accuracy

2) use the matlab gradient function

Current (mA) Voltage (V)
65 5
230 7
760 9
2300 11
4000 13
6300 15
9700 17
14600 19

syntax at http://www.mathworks.com/access/helpdesk/help/techdoc/ref/gradient.html
a=[5,7,9,11,13,15,17,19 ]

a=[5,7,9,11,13,15,17,19 ]

> gradient(a,b) // Here we want to differentiate a with respect to b, this can be done using gradient command in matlab

ans =

Columns 1 through 7

-4.7619 36.3636 1.9324 1.2346 1.0000 0.7018 0.4819

Column 8


NOTE: My values could have been much more accurate if i interpolated the values and wrote a m-file where the it is checked with the gradient and at the point it increases o.2 the value of the voltage is output .

But lack of time stops me, hopefuly after the exams i will get time 2 finish the post.

30 days more and counting

Yes its been a hard semesters work and just 4 weeks more for the grand finale.

studied more things this sem than all 3 previous years combined.

Challenge is to complete all the course work and econ assignment successfully and start working out past papers.

Only 4 weeks to complete all this and the subject that i am repeating electromagnetics.
