Tears

Quote of the day:- Don’t think of building a stairway to moon, you wont have anything for it to rest.

Tears flow down my cheek
My throat is clogged with emotions
I cant stay normal even if i try to be
All these emotions getting on me

Not lamenting on something unfortunate
Just grateful to the God
The wonderful gifts he bestowed upon me
Life of luxury i am entitled to

Looking at others grieving
On their losses irreparable
Makes me smile at my life
Distanced i might be from my loved ones

Still with me they are always
They are in this world
Looking after me and smiling at my achievements
A source of strength for my future endeavors

While i am here to live
With, the ones i love
They are left reminiscing of the golden past
Trying to get some shine in the murky present

Thanking God for all the years of joy
I have had all my life
Praying to the almighty up above there
To provide strength to the deceased
Strengthen the shoulders of the pallbearers….

Dedicated to families of Hyderabad Blast victims and to my cousin sister who must have spent the first rakhi without the arm of her real brother to tie a rakhi..

Of NLP and Rockford

A summer project and one and half months into LTRC and being inducted into LTRC family(as my frnds say) and being kicked out(not given Summer Internship Money 😦 ). I just can’t help but be amazed at the amazing capability of human brain to parse the natural language. The incident which made me think about this thing was a statement made by my friend to another
” Abe newspaper de dena yaar, pavitra karne hain :P”
I hope you must have understood what the guy was talking about.. If you havent then keep reading later and you will get enough hints about the act committed by most (almost all) guys. The real thing was that without any background statement or anything of that kind,the other person completely understood what the guy was saying. I have seen some projects and papers and so many algorithms and methods have been tried and people keep trying and even then if they can get accuracy levels in range of 70% then its great and for that, i am sure they wont be considering such phrases which can be sort of Idioms but not famous at all, just framed at the moment. You can’t do anything but be amazed at the ingenuity of the supreme, the creator.

Now to Rockford, a movie about which i have heard so much and whose songs i have heard so many times that i have been dying for years to watch the movie and finally i watched the movie. Any mention of the movie without the song YAARON by K.K. is just incomplete. If “Smells like Teen Spirit” is the youth anthem in English then for sure “Yaaron” is the youth anthem for Indians in Hindi. K.K. will be immotalised for the song atleast for our generation people. Now coming to the movie, i was really impressed by the an Indian movie freely talking abt shagging and all. It is such a common place activity among guys(dunno abt gals… :P) but no teen movie ever talks abt it. We can talk about sex,but shagging is a big no no always. All in all a good movie, worth watching for one and all, though i think that they could have done better with casting some other girl as the love interest of the protagonist. One more thing was, I was thinking Nandita Das would have some rule but she just walks 2 times wishing good morning to the guys… What the crap…. But the picture sure reminds of the good old school days.

PS1:- Dil full pet houseful… Went to a buffet for b’day party of a few guys and once again i trumped Pk n Chand in eating more… hail me!! 😀
PS2:- For the uninformed, they are the heaviest eaters in mess and canteen and i eat measly 2 rottis and some rice in the canteen
PS3:- Go through this link and i will change my blog name if you didnt ROFL.
PS4:- Two Profs on leave, last 2 days => Chhutti for 2 days and with weekend coming, this week has been nothin short of fun
PS5:- Finally started using my keyboard again for the first time since coming to OBH,that is 1 and half month now.
PS6:- I hope you got what “he” meant by pavitra karna… 😛 I talked abt it a lot
PS7:- Listening to AC/DC for the first time today.
PS8:- Watched a movie after ages yesterday.. I always think of watching movies but end up not watching them and not doing anything at all.

Childhood

Strolling through the park
I see those cute little faces
Playing their own games
Having the time of their lives
Tensions a far cry for them

The power they posses is greater than any
A cute child can make you smile
With their inquisitive eyes
They look upto you
Questions  myriad filling their minds

Looking at them i remember the days gone by
Those days of fun and frolic
The period of tension free life
Walking with a spring in step
Dreams of flying so high

Of the spirit not perturbed by expectations
Not a care about the future life
Confidence to fall upon others when troubled
Strength of the family so close behind you
Comforting hand of your father and the warm heart of your mother

Now a grown up, you walk all alone
Living life the way you want to
Taking decisions for you and people around you
Shouldering the responsibility of everything you fuck up
The life in a new form, the life a bit matured

Difficulties ease into life
Crisis become a feather on your hat
Thats how you have to live as adults
Looking at the toddlers and flashing a smile at them
Letting them think the world is still a good place to live in

While you live your life
Fighting for everything you need in your life
Trying to make the world a different place
For you,for me,for generations to come
Life for the unborn, relation for the unwed

Was in some sort of daze while writing the last portion specially the last paragraph was feeling as if i am in some other world was writing whatever was coming to my mind… just going with my heart.. So might not make that much sense..

Song of the Day -: Maybellene by Chuck Berry
PS1:- My blog turning into my poem diary these days 😛
PS2:- My mouth ulcers finally healed
PS3:- Mid sems came and went as always, nothing eventful
PS4:- Life is so dull n boring these days
PS5:- Chuck Berry roxx.. Awesome lyrics..

“He never ever learned to read or write so well
But he could play a guitar just like he ‘s ringing a bell”
Just listen to the song Johnny B Goode… to feel rock n roll..

Mr. Kalam at IIIT-H

The day that we at IIIT-H had been waiting for quite some time finally came. It was announced some time back that Mr.A.P.J.Abdul Kalam will be joining IIIT-H as distinguished faculty and will be coming to our college on 15th August. With excitement we were waiting for the arrival of the dignitary.
Earlier it was scheduled that he will be coming after our cultural program ends but a few moments after it started, there was an announcement by the anchor Karan that Mr Kalam is going to arrive sooner than expected. And there he was, X-President of India Mr. A.P.J.Abdul Kalam, first glance of him from near and for some reason he looked plastic to me, nt a human.. I dunno he ws so strange looking… i cant point out what but it ws strange.
The moment he set his foot in the tent and came near the group of us students sitting there, who all stood up to see him (we were lucky in that respect that we were on the left most side from where he came), he was just enignmatic and charming. Standing to pose in front of someone who was clicking a photo. Waiting to talk to a few people (regretfully only girls 😦 ). Then he gve his lectures after the cultural program. Which is nt much to write about.
Here are a few photographs of today…

Mr. Kalam up close…

Mr Kalam’s Autograph which i got…

Unfettered Love

Once we were so close together
It seemed like she would be with me for eternity
It was as if she was made just for me and me for her
She was the world for me, the source of my happiness

But the fateful day came and she departed from my life
The last meeting with her on that fateful evening
Tears flowing down the cheek of sky masked my tears
The same rain looked on her face as tears

She went to a place far far away from me
The distances all snatched her away from me
I was left there to brood all alone
While she found the love of her life in the place new

She found in him a support I never could give
She found him a man, i could never be
She was done in by the charm of that stud
While I stood her trying to gather the shattered pieces of my life

The gale in my life turned into a storm
Sunshine of my life marred by ugly clouds
The tree of my life uprooted by the storm blowing
I can only see the gibbet of despair in front of my eye

I am still trying to find that beacon of hope
Waiting for the love of my life to be mine again
As they say, set your love free to make it yours again
Living in the hope that the bird of my life will return to the house of my heart

Song of the Day:- Ek Hockey Dungi rakh ke from CHak De India

PS1:- Wrote 5 PSes but they got deleted nw nt in a mood to write any PS
PS2:- Btw had 7-8 cups of coffee from the coffee vending machine in OBH as chand’s coin got stuck… Some people had even brought thermos but then we told the guard and the machine was switched off..

Life Mein BC….

FOR THE UNINITIATED BC IS TIME PASS AND NOTHING NON-VEG, IF YOUR FILTHY MIND HAS THOUGH OF SOMETHING ELSE..

For non-IIIT-H ians.. all that is written below happened through a series of mails sent to the intra IIIT-H “Life” Mailing list which has been set up for discussin general student issues…. 😛 and nw you will see what the student issues are… 😀

It all Started with Naga Sitaram raising a valid point about Telugu movies not being screened in the Movie Club saying that in his 1 year stay in IIIT, he hasnt seen any telugu movie being screened in IIIT.

Then pavankumar_g,bhaskar_kakani,gaurav.kharkwal sent mails supporting the motion

Anita,Anusha V,suman_chalana,radhika_b,bhima all agreed with the motion and mails kept flowing

Then Maneesh Upmanyu sent a mail asking people to spare the mailboxes

Padmini was vry excited with the prospect of telugu movie,sandeep_digavalli said that hit telugu movies hould be screened instead of flop movies like Naqaab and all

Then Suryakant Patidar aka Pati sent a mail saying “Yes, I can’t wait ………….
Next mail : life-unsubscribe@students.iiit.ac.in”
you can understand his frustration but if he did this, then he missed out names of a lot of awesome movies. and such great BC…

Sashidhar chips n frustrated with this mail
“Your passion for telugu movies is undoubtedly admirable. You guys have put your point across in a great way…
But please spare my INBOX……….. PLZZZZZZZZZZZZZZZZ”

ganga_t,santosh_puram,Karunakar Paturu also agreed with the concept sending mails to remind us.

FIRST INSTANCE OF BC
Sanket started the bc with the mail titled Untiy in Diversity
————UNITY IN DIVERSITY————–
—no matter whether it is telgu or hindi—

Rameshsoni asking “Why not Rajasthani,bangali,Gujrati,Tamil,Haryanvi,
Kannad,Malyalam,Marathi,Bhojpuri,Malay…………………..”

satya_vs said “If anyone have to discuss about “Screening Telugu Movie” AND “OBH
Groundfloor Mess” i suggest you to please from now onwards send to
life-unsubcribe@students.iiit.ac.in” dont know what he intended to say… but ok..

Kiran V Neelisetty also agreed with all of them..

khandelwal said that telugu movies should be screened

Nishant Shobhit wanted Telugu Movie “Bangaram” and Marathi “Gheum Tak”

kiranm sent a mail in telugu with line by line eng translation and was very happy to see such a huge response and hoping that this idea will be implemented

Thereafter all hell broke loose and bc started…
FINALLY BC STARTS
Vaibhav Bajpai saying “From last three years i did n’t see any Bhojpuri movie in movie club. I want to see spiderman-3 in bhojpuri.”

Akash Deep wanted the screening of bhojpuri movies “humka hau chahi” and superhit “ganga”

khandelwal says “Now bhojpuri movie also becoming famous.so by not bhojpuri.” Now this is mc++(mail count++) like PC++

Sankalp wanted to see a marathi and a gujarati movie..
“1. marathi: andharya raatri diva tujhya hatat
(which was remade in hindi as “andheri raat mein, diya tere haath mein”).
2. gujarati: tamaara maatey mhaari jaan
but before all this, i want ground breaking acts by Prabhuji, Loha and
Gunda to be screened.”

Maneesh Upmanyu warned people to stop this or they will be banned from life mailing list

But Saurav Khurana our batch topper sent a mail requesting for harayanvi movies
1. kuaara baap….
2. meri kaan mai jua…
3. teri baal mai kua…
4. Lado ki maa (part 2)

Badrinath also wanted to see the greatest-est movie Shivaji and some B-Grade Turkish Movies deceptively titled “Emret komutanim : Sah mat” and “Emret komutanim”.

By then a guy named Himank Sharma got quite bored with this action goig on and he nt being involved so he sent a mail asking the greatest Hindi Movie “Chhamiya” which has got awesome dialogues to be screened…. You hav to be a guy in IIIT to knw the special dialogues of the movie

Then Ankur Khare wantd “to see monica bellucci in action, screen Italian movies! 😀 ”

Abheet Bharti wanted Punjabi Movies too..
1. badla jatti da
2. jatt di pasand
3. kudi punjaban
After all, if everyone is coming to party, why should punjabees be left
behind?”

John said “idhi voora keka!!!” Dunno what it means.. Someone comment on the post telling what it means

Rahul Chauhan wanted the “screening of top most regional film “Dhakad Chhora” which
made a collection of 2 crores :).”

Finally Nishant Shobhit(Moderator of Life Mailing List) put his foot down saying
“Thats enough folks!
The DNS is down and emergency traffic moderation cannot be enabled right now.
Spammers will be banned permanently from the list.”

Even after that Ankur Jaiswal(ankur_j) wanted to see “teri lungi mera ghaghra” or “sasura bada paisawala”

After this Shrikant also sent a mail which was moderated in which he wanted to see the following Pappu series movies
1. Nappy mein Pappu
2. Pappu bana Champu
3. Pappu aur Chacha Chaudhary
4. Pappu wants Punjabi Cats( u knw the odr wrd)
5. Ye pappu pappu kya hai

After this final mail from Nishant Shobhit
“All traffic moderated.
ankur_j banned.”

Finally the saga ended with a total of 48 mails in a little over 2 hours…

This was a most pleasurable experience and i will say Life mailing list roxxxx… This goes to show that how we IIIT-Hians do BC… Mail pe BC.. Gtalk pe BC (status messages).. BC hi BC..

Arz Kiya Hai

A few days ago, i started writing sher(if these can be called so) and here is a collection of 10 of them which i have written in the meanwhile… This is my first attempt at this form of art, so cant say anything about the quality of them, hope you find them good….My attempt will not satisfy all the conditions of she, if there are any , but i get the feeling of them being sher.

1) Unki yaad mein humne rat bhar ki chand se bat
Wo to na aye unki yaadon ke sahare rehne ki ho gayi aadat

2) Aaftab sa tej unke chehre mein, bit chandni si komalta unke ehsaas mein
Jheel si gehrai unki aankhon mein, Raat sa andhera unki zulfon ke saye mein
Mere mehboob ka to kehna hi kya
Khuda bhi soche hairan hoke khoobsurati kaise aayi insan ki kaya mein

3) Hawa ki sarsarahat unka ehsaas layi
Barish ki cham cham unke paadep ki chanak layi
Us Dilruba ki yaad mein humne raatein tanhayi meni katein
Uske aane ke intezaar mein humne uski tasveer se hi baat chalayi

4) Humare gam mein unhone ashkon ki nadiyan bahain
Hum aise bhi bewafa na the
Ki jab bhi humari yaad ayi unhone apni kashti hi dubayi

5) Vo pardanasheen humnasheen se ban gayi dilnasheen
Unki aankhon ki gehrai humein dubati le jaye
Is ishq ki to dastaan hi kuch aisi hai.
Takthon-tajon ne iske aage sar jhukaya hum to akhirkar insan hi hain

6) Us pal ke intezaar mein palke bichaye baithe hain
Unke deedar ki aas lagaye baithe hain
Wo kya kayamat-e-din hoga
Jis din vo khwabon se nikalkar humari aankhon ke saamne ayengi

7) Aap ne humein sar aankhon par chadhaya aapki meharbani
Is nacheez ko tareef ke kabil samjha humari khush kismati
Ye to sab unki mohabbat ka asar hai
Is jeete jagte insaan ko shayar bana diya

(This was written as a reply to status messages of all my friends which showed things like “Himank the new shayar on the block” and other things)

8 ) Gham-e-Ulfat mein humne khudai se bhi ki dushmani
Sara jahaan ek taraf unki yaadon ki gehrai hi nazar aayi
Unki sohbat ke intezaar mein humne apni hasti hi mitayi
Jis Din vo saamne ayi kayamat bhi sharmai

9) Is haseen ehsaas ke liye alfaz bahut hain
Zindagi ki gaadi ka ek pahiya hai ye
Is nacheez ki kya aukat ki Dosti ke bare mein kuch bolo
Ye to hai vo paak jazba jiske aage mohabbat bhi sar jhukaye

10) Uska ek ashq duba de mujhe gamon ki gehrai mein
Uski ek muskan mita de mere saare gamon ko
Zindagi se bhi pyari hai vo zindagi ki dor meri
Uske bina to ab meri zindagi ki ummeed bhi nahin hai

(Dedicated to my sister..)

Lucky Ali

I searched far and long and tried many type of music and many singers but somehow the comfort and pleasure which i have in the company of the songs of this artist named “Lucky Ali” can never be duplicated.
I was introduced to the music of this soul strummer through the songs of the movie Sur and since the association has never dwindled. I have been and will always be a fan of Lucky Ali. I always say that Sachin is the God of Cricket and if there is one person whom i would place as his equal to in music, it is without any shade of doubt Lucky Ali.
You can feel the harmony in his music. His music always touches a chord in your heart be it the light mood mausam, love songs like O sanam, Dark songs like Mehboob. One thing which i jut adore about him is that his songs have a variety of emotions. His repertoire consists a variety of songs.
Somehow i have always heard the complaint by people that all his songs sound the same while i on the contrary feel that he has quite a lot variety in his music listing, more than most of the Indian Artists we have. One reason for this which i can think of is people dont listen to most of his songs but have heard only the most famous ones or the movie songs while his best songs are the not so popular ones… According to me his movie songs listening to which people like his music stand nowhere in comparison to his albums.
One truly awesome quality of his songs is that many of his songs can lift up your mood whenever you are down, i for my part turn to his music whenevr i am down and out. One of his song Mausam has a strange quality (atleast seems to me), it seems a very cheerful and happy song whenever you are in light mood but it becomes a saddish (if i can use the term) when you are down, which i have experienced.
His first album Sunoh must have been a huge hit, i dont know much about then coz it came in 1996 when i was just 9 but the album stayed 60 weeks on MTV Asia charts, which is quite an achievement 😛 as far as i think. He had this habit of releasing albums every two years with Sunoh in ’96, Sifar in ’98, Aks in 2000, Gori Teri Aankhein in 2002 and Kabhi Aisa Lagta Hai in 2004 but the year 2006 went on without any album of his.. 😦 and i just kept waiting. Its 3 years since his last album and i hope he releases something soon.. 🙂
I would suggest any music enthusiast to listen to his music, specially the Album Aks…. which by me is the best of the lot..
If any Lucky Ali fan reads this and you want any song of his, just tell me and i will be more than happy to send you any song of him if you want and I on my part want the song “Aap Par Arz hai ” from the album “Sunoh”, if you have it then please send it to himanksharma@gmail.com

One more speciality of the guy is that h writes the lyrics and composes the music of most of his songs besides ofcourse singing them.. He is so multitalented.

Some songs of him i would suggest everybody to listen are
Mausam
Mehboob
Aap par arz hai
Sandesh
Nahin Rakhta Dil Mein
Sifar
Ofcourse the popular ones like Dekha Hai Aise bhi, O Sanam…
The list just goes on n on

Song of the day :- Aap par Arz hai from Sunoh.. Miss listening to this beautiful song so much..

PS1:- Mid sems approaching
PS2:- Project meeting on 9th and we havent done an iota of work, somebody please help us out.
PS3:- Weather is changing and i caught cold … Not good 😦
PS4:- Even if its boring read to you (which i hope shouldnt be) then please read in the name of Lucky Ali.

Senescence

Time is flying past like a gale
You are standing still and quite
Each day seems to bring new hope and life
In the end, it also passes with no events

Big hopes rest on the plans for future
As the day passes they are again pinned for some day later
Promises are turned down,hearts are broken
Hard tasks give leavage to petty amusements

Days morph into weeks and then into years
Time passes by waiting for none
All the things around you change
You become old and the youth flows to others

One day the realisation dawns upon you
When you’re sixty four sitting in your lawn all alone
You realise that you should have gone after your dreams
It becomes a phase to relent for the wonderful years gone by

Song of the Day – Nam Ada Likhna from Movie Yahaan

PS1:- Assignments started again.. BAck to IIIT life
