Me and IC 7486

Its was semester Exam day.It was digital circuits practical exam.
Unusually i arrived 10 minutes late for the exam,yet i was not nervous.:)
As any practical exam i submitted the record and picked a sheet in the lot it said "DESIGN AND IMPLEMENT HALF ADDER AND FULL ADDER CIRCUITS USING LOGIC GATES" Surprised to get such an easy experiment at sem exam, i began with aim,apparatus required,circuit diagram,truth table,procedure and ended with result.It took me 2 sheets to complete the writing part of the experiment.
Now, its time to connect the circuit and seek the output.
I went to fetch the components,there were so many 7486 IC's. Then i connected 7th pin to ground and 14th pin to +15V(thats wrong,it should be connected to +VCC terminal)

The rest of the connections were made in a few minutes and i switched ON the power.
There were fumes from my circuit,unusually....
It was a fraction of a second that turned left,right,towards the tutor and also towards my fellow student to check if they have spotted me and my circuit with fumes..
Oh Thank GOD,no one spotted me.Well i have burnt an IC,the 7486 IC.
Replica of a CRIMINAL HIDING HIS CRIME,i was stead fast in blowing the fumes away and took that IC out of the bread board with my hankie :(
I'm in damn need of a new 7486,what to do??how can i let the tutor know that i have burnt an IC??
If I let out the truth it'll fetch me a black mark.I lied to the tutor.
I said to her"EXCUSE ME MAM,I NEED AN IC 7486,THIS ONE IS BROKEN"(Its burnt actually,anyway its useless so I broke a pin and made it a scrap)
I feel bad to have lied and i'm telling about this crime to all my kith and kin,to feel light after committing a crime thats the reason behind this post...

Now I'm with a new 7486 IC and I was bit more careful with this one and successfully
completed the connections and the output was perfect and got it verified too..

All the tasks at the lab are over now and its time to leave.I'm supposed to disconnect the circuit and place it ready for the next batch of students to engage in the circuitry.
The process of disconnecting began,I pulled the wiring hastily and pulled the IC's hastily because its all over for me and I'll be leaving the lab in a few minutes.
The proverb proved itself "HASTE MAKES WASTE"..yes the same old IC 7486's pin got hurt,it got fractured badly,it is supposed to be pointing down but then it was pointing right..what a mess!!! Second crime!!!My heart is weak to bear this...

This time I rolled it up in a couple of wires and placed it in a corner of the table and disappeared from the lab...
This is how even the lame ones become criminals...lol...

The closed gates....

The closed gates of my school.The gates will never open for me again.They were open for 14 years for me.It haunts me.
There were thousands and thousands of dreams right from lower kinder garden to Higher secondary Second year.Some of them got shattered and many came true.
I'll share one memorable happening in each class.


Lower kinder garden(L.K.G-Section-D)-In my class we used to have soft toys on the cupboard.It was so tempting to cuddle it.One fine day me and my friend,kidnapped it in the afternoon(the practice is that LKG kids will be put to sleep after lunch and class teacher wont be in sight,it was a prefect time to steal the toy)and played the usual Doctor and patient game.I was the doctor because i was the one who got on the bench and stole it from the cupboard.And the toy was the patient, my friend was its mother.She brings it to saying that her son suffers from fever.I mercilessly took a pencil sharpened it and poke it on the toy's hands.Then we rolled into laughter and was having fun.It all went fine and as my fellow students were asleep.All of a sudden i could hear the sound of anklets and yes it was my class teacher on inspection.I warned my friend to place it somewhere and pretend to be sleeping.She was stubborn and teacher came,she got caught, I successfully pretended to be sleeping and i escaped...hahaha it was so nice to see someone getting scolded...

Upper Kinder Garden(U.K.G-Section-D: Well this was the class were i was branded as a rowdy student.I keep on talking to my friend,meddle with things and get caught,kneel down and finally my parents will be called.There were lot of activities going on like my school has two campus-the old campus has L.K.G to 3rd class and the main campus(new campus) has rest of the classes till higher secondary,and the practice is that both the campus will have separate sports day and annual day celebrations,i used to participate in March past(thats one thing i love in a sport day).As a student of U.K.G i took part in choir for kinder garden graduation ceremony wearing the black coat and all.I still remember an hour before the commencement of the ceremony my class teacher applied lipstick for all those who take part in the choir,and there was the refreshment committee filling the tiny lipstick applied mouths with lemonade.Its like yesterday, time rolled like a lightening thundering our hearts with painful past.
here is the picture of the choir for Kinder Garden graduation




Thats me!!




well i'm stopping this post here still lot of stories are left unsaid..
To be continued..:)

Watched GURU...

Its more than a year since the movie GURU was released.Its today that i watched it for the first time.I have a habit of learning something from any movie.Well i learned to say "I'll excel no matter what". Guru (Abishek) will keep on saying "I'll excel come what" and it makes me feel good to listen to such positive words.I enjoyed each and every dialogue, specially the words from madhavan to convince the gal to marry him.Over all the movie was good!! I felt that there is some ambiguity in the court scene where Guru talks about his hard work and all in the place where he is supposed to prove that the cases against him are fake..

Rest of the movie is good....

PATRIOTISM AT ITS EXTREME..

This scene was captured at North Coimbatore bus halt at Coimbatore on 18 August 08.
I could feel the depth of patriotism by looking at the horns of a corporation worker(bull).

violin class-day 1

My long term dream and wish came true today..it was to learn to play violin..
today was my 1st violin class.IT was fine.My tutor asked me lot of questions.they follow..
tutor:whats ur name?
me:dharini
tutor:what do u do?
me:2nd year B.tech IT in HICET.
tutor:do u listen to carnatic music?
me:yes i do..
tutor:hmm..which carnatic singer do u like?
me:priya sisters.
tutor:fine..which song do u like?
me:brahmam okkate..
tutor:...why did u choose to learn to play violin?
me:music from a violin is smooth and divine..thats the reason..
tutor:whats the use of learning music?

one of my classmate entered the hall and he was engaged in a conversation with him..

tutor:so u dont remember even 1 use of learning music?
me:(actually i paused to not to interrupt him)IT makes us divert from our routine,gives relaxation,...
tutor:hmm...we usually ask such questions to every student..dont bother..
me:(tiny smile played on my lips)...
tutor:Violin is the most complicated instrument of all...guess why??
me:my guess is because in violin we used two tools(the bow and violin part)...
tutor:...mmmm...so practice daily..
tutor:how is sound produced?
me:when two objects collide sound is produced..
tutor:exactly..but u r too specific..i say in general sound is produced by the vibrations

the class started and he taught for a gal then asked a boy to play as a test,then came a small boy of 7th class,he too is learning to play violin.
it was my turn to learn, follow carefully and learn the theory of violin with me.





I'm learning carnatic music in violin so the posture is important.
you sit on the floor with legs crossed.then stretch your right leg so that your toe is just in front of the left knee cap.rest the violin's scroll on your toe.you lean towards the violin and violin placed towards you ie., on you.fine..
Now the bow handling technique, it was quiet difficult for me..here it goes..
hold the rear end of the bow with thumb and middle finger on either side.fore finger little above the middle finger, spread your fingers for a comfortable hold.while bowing your folded palm should be parallel to the bow, this prevents wrist pain and shoulder pain aftermath..

Now the bowing part:bowing is sliding the bow to and fro over the string with constant slow speed and less pressure.
if u press the bow towards the string it creates a jarring sound and same results if you bow very slow..

i was good at it. tutor said "you are really good for 1st time bowing.."
awesome??? yeah i rock!!!
then was the class for other two students and i was staring at them and the first class was done..
Tutor asked me if i had any doubts, i said no..(i meant i dont hav any doubts in my part of class) he said doubt arises only when you have interest in this..i felt ashamed i'm realy interested in this..its okie for first day of class...i really enjoyed it..i'll be buying a black violin the coming friday and going play it till my craze is lost...
mine..

VIVA VOICE-my 1st viva ever..

It was Fundamentals Of Programming practical exam 1st semester B.Tech IT..

my question was "WRITE A C PROGRAM FOR SEQUENTIAL SEARCH USING FUNCTIONS "

I'm a crazy biology student i usually flop in cs at school.it was my 1st ever computer science practicals and my 1st ever viva voce, guess what i did...
i wrote a program for sequential search without functions and executed it too.i felt great and was top of the world to see my program execute and the output was exact.
i called the internal examiner and she too checked my output it was exact and the big fun is that she too didn't notice that my program was without functions.

i was in cloud nine and next task was the viva voce .

i was called..here is the exact conversation..
external: what is your name?
me: Dharini
ext:what is void main?
me:(blinking,flopped)sorry dont know
ext:what are library functions?
me:when C- software is installed in PC there will certain files of it which are fixed cannot be changed are installed. whenever the C-software during execution of a program needs some help with basic functions it uses these files...blah blah...
ext:(shocked)hmmmm...C-software???
me: no sir C-compiler..
ext:(still more puzzled)C-compiler??
me:yes sir..
ext:hmmm...what is C??
me:its a programming language sir...(as if he doesnt know it and i only know it)
ext:what is knowlegde and information?
me:knowledge is what we know and information is wealth(yeah the same dialogue from movie called"BOYS")
ext:(almost broke into laughter)......
ext:hmmmm...some examples of library functions?
me:strcpy,strlen
ext:why are you considering such complicated ones...you can very well account for simple ones such as printf , scanf...
me:(a tiny smile playing on my lips)(therinja solla maattoma)....
ext:what is an OS?
me:operating system.1st line of software installed on any PC.it forms the base for all the other applications to function..blah..blah..
ext:(satisfied)....
still some more questions...and my 1st ever viva is done..

i was the second one to get OUT of the lab..i felt great..
the guilty feeling is still deep in my heart...to have written a program without functions...and i'm not fit for this thing...


but all that is wrong..i'm the one who is made for IT...i scored outstanding grade in Fundamentals Of Programming practicals..
this is the only incidence which gives me confidence and keeps the heat for my profession... i rock!!!!

class foto 1st standard D section

attending school sports day,when u r a passed out.....

it was 27 jan 2008,sunday....
i called my friend,asking her to accompany me for attending the sports meet at my school.After a long convencing and sweet words,she said"YES".
PLACE:At my school gate.
TIME:11:00 a.m

Me & my frnd stood outside,not knowing if we will be allowed or not...suddenly
security:welcome..why standing outside..
me:how r u anna..
security:fine,go enjoy the sports day...

At first sight Principal sir(we call him VP sir) was busy talking to the staffs.I and My frnd stood still,hoping he would turn to us.He did turn to us,said"How r u ma.."
I & frnd said"fine sir,how r u sir? congratulations sir!!"
he said"fine ma..congrats for?"
i said"for becoming the Principal"
sir said"Thank you ma..do come for annual day"
me & frnd said"sure sir"
We walked straight to canteen,staring at everyone,hoping to find our frnds.Then got something from canteen and started chatting,chatting,chatting and chatting.
All of a sudden caught sight of Chitrakala mam,we both were so excited and almost ran towards her.Unfortunately she was too busy at the day's proceeding,so couldnt talk to her.We walked slowly saying"somehow we must talk to her"to each other,then saw sudha mam(we call her sudha miss,she is so strict & perfect in english & a teacher of physics)
mam:how r u ma
me:fine mam..how r u
mam:good..what r u studying,which college.
me:B.Tech IT in HICET.
mam:mmm...good...
she asked same thing to my frnd too..

then both were roaming thro the corridor..it was geetha mam..she too enquired abt the college & dept.all this happened near chemistry lab(where lot of conical flasks & test tubes were broken by me)AT school,whenever i see her i'll try to escape from her sight,coz she is the HM & of course i hav fear on her.then on the way to first floor saw Indra mam(the lab demonstrator,dept of phy)

Now at First floor:
Caugt sight of Padma miss(teacher of chem) before meeting her it was Ravi sir walking behind us.
About turn!! and started talking to him.What a surprise he said"Dharini u changed a lot"My frnd "Yes sir she is the cls rep it seems".he said"oh!u really changed a lot"

Now Padma miss...said"who is this actress?????".me thinking"oh my god is she saying abt me"
oh god she is teasing me...she was too good that she talks only truth all the time.She too said"u changed a lot"
Then walked all the way thro all the classes & corridor..on the way met sarojini mam,and still many tutors....

Six years' dream came true..i wanted to get inside the elevator..yup got inside it & checked my beauty at the mirror..then came a voice"akka there is no power".enna kodumai sir...chinna ponnu kitta koda bun nu vaanganuma.....
alright,both walked down the stair,stopped a 4th std girl,got her certificate and said"congrats u r 2nd in beginner's 100 feet running race"I gave a hand shake too.

It felt like heaven roaming all thro the building,with dreamy eyes,chatting,chatting...still more chatting..laughing...just enjoyed..

wow!!what a day !! I enjoyed it to the core...
oh my god! it was time to leave,we both had to part our ways..we had been talking for 3 hours but felt there were lot of things left unsaid....
then things ran thro the memory lane"tomorrow i got tests in EEE,Material science...Oh yes got to be a responsible rep....etc,etc...got to wake up at 6 am...and the usual so called busy life"...

she's good...

she looks good....
