GnuPG and Chksum

I am not a person to explain all the cryptographic theory that works behind pgp and chksum methods..Because I got only a C grade in the last endsem in the cryptography paper..But I can explain you how to use this tools.

When you download a zipped file you can get its corresponding chksum(MD5,sha1sum , sha224sum sha256sum ,sha384sum, sha512sum and so and so.)It will be basically a line which looks something like this
959bdb934e3a72d256bfbd0122d996a73adb5d1f gnupg-2.0.9.tar.bz2
Now just create a text file ,give some name to it say a.txt and copy the above line to it.Place the file in the same folder which contains the zipped part.Invoke the terminal(of course in linux systems) and type
md5sum --check a.txt
or
sha1sum --check a.txt
so and so depending upon the sum that u received.If ur zipped file is untampered it will return 'OK'.
So thats all about Checksum checking.

now to check signatures.
Download the signature.say let the file that contains the signature be xxxxxxxxxx.xx.sig.
Place the signature in the same folder which contains the downloaded file.
Run " gpg --verify xxxxxxxxxx.xx.sig ". If everything is fine u should get an OK message.

Thats for now......

Kill me please.........

I am so happy that I have to pen down it some where. I have been assigned the task of setting up a mail server. I started the work last wednesday,and since then I have been glued to the computer .It has been a 100% devoted work but things were not coming in my way.And I could not free my mind either, a sort of mental torture....And thanK God I finally could send a mail throug it.A desperate trial and error run has now been successfully completed..Kodos to me:)

The result of the previous sem will be announced tomorrow...Feelings? Well, its a don't care attitude right now.And it has to be the same tomorrow.After all I am 21 years old (young,even though many here call me valyettan) and its high time to get freed from such silly thoughts...

Setting up a mail server

Its vacccation time.But I am still at the college.The task assigned to me is to set up a mail server for the institue.
Nowadays I am doing a lot of technical stuff that I plan to start a technical blog.
Or at least I should have a blog that some body reads.Its nearly two years that I have been all alone in this blog world.But should say that I am a big fan of myself..and its the reason that I continue to blog regularly.

The pending list is now

1.The anatomy of B tech curriculum in computer science
2.Falling in love with segmentation fault.
3.The great great Bulls and Bears .

Two more to it.

4.Compiler construction
5.Mail server

All the above mentioned are technical stuff. Thats why i plan of starting a technical blog.

An end and perhaps a new beginning

Its the end of another semester.And as I had stated earlier an eventful semester.And I have managed to perform extremely poor in all the exams.Cheers to me :)

But I strongly feel that I have learned more things in this semester than in any other period of my life. So no worries about GPA.Also I could find answers to almost all the questions that prompted me to take computer science.Not big things , just simple matters like how internet works,what are protocols, how a compiler works etc etc.

Now its time to some serious learning.Things are getting clearer and clearer. The saddest part is that this could have been done earlier. A waste of two years is what it counts in the end.Pavam njan........

Now should get back home tomorrow..missing amma and achhan quite dearly..missing the palakkadan kattu..missing the ambalakulam and the aalthara of kuttiyamkavu bagavathy kshetram ...missing the 'saranam vilikal ' of the swamimar.....

with love

The art of living

There was a period, I suppose some where after the 1 st Sem that there was something at the backdrop of my mind which disturbed me quite badly.
I was struggling to figure what I was doing at NITC.I have been a computer science student and still I did not have any idea what computer science is all about.The classes of maths, EC and Electrical was hell for me.I could never never understand why I should study bloody network theory,intricacies of motors,higher integeral and differential equations and the likes.Mugging highly useless 'substances' and vomiting it in the examination paper had become a routine exercise during the period.It was all done when my mind was struggling to find out what my dearest computer science could offer me. And it continued , perhaps till the end of fourth sem.


Well, I intended to write something else.I somehow deviated from the topic.May be I would continue at a later stage.As usual,let me pen down its heading,
"The anatomy of B tech curriculum in computer science".So two posts are pending now.
1.The anatomy of B tech curriculum in computer science
2.Falling in love with segmentation fault.
Add to it,
3.The great great Bulls and Bears , and lets make it three.


Now coming to the topic which I really wanted to write in this post.I have a feeling that I waste a lot of time in planning:
Planning the days activities,Planning studies,planning future etc. And often much of the time is wasted on it.Not on the execution but on the process of planning.Now I think its time for me to stop that habit.Continuously worrying (or may be perhaps thinking about the future) is sure to kill you if you have surrendered to it.It makes the life hectic.Pointedness is what u require in your life.A complete dedication to what you are doing at the moment, a state of 100% concentration.It makes the life more comfortable.It spares you a lot of time and energy.I have always felt that its not the tight schedule but the mental exercise of worrying about the schedule, really makes the life miserable.I wish for the day (or perhaps a mental state to be more precise),when I could completely free my mind from all anxieties about the future, from all regrets about the past.I wish for the day when I could say 'I Live This Moment'.Good luck me :)

Good night!

A quick post before I get to sleep.

I simply want to say to myself that

Happy ending.

Yesterday was my compiler lab exam. I had figured an E grade in the previous exam and hence yesterday's exam was a bit crucial for me.This is one lab for which I had spend nearly 80% of my study time.It was really great experience.But I had a terrible time in convincing Selina mam , that I did not copy and what I was showing was my own work. Mam seemed to come to the lab with a bit of prejudice.It felt to me that she had already made up her mind whom to give 'S',whom to give 'A' and whom to give 'F'.Once you make a good impression , its easy going. They will hardly look into your program.Else, Its going to be hard time.I was a bit disappointed at this.Because I was always bad at impressing someone with my communication skills. But soon I got used to it.And happily I got an A grade,yesterday. But the most happy thing is that Vigil,my lab partner, managed an "S' grade.:)Kudos to him.

Well this is a lab which taught me what programming is.Now I feel that I have become more confident to approach a problem.Programming is an art. And any artistic work requires immense amount of concentration,skill and taste. I call programming an art,because programming requires all these.U need to have immense concentartion else you can be sure that you are going to mess up everything.By skill, I mean the ability to think and analyse.Thinking is the core of programming. Its really ammazing to explore different paths so as to solve a particular problem.And finally taste,well this gives you enough endurance or keep ur tempo till the last.
"The biggest reward of love is the feeling of love ".Similarly ,"the biggest reward of programming is the feel of programming.".This is something to be experianced. I am happy that I had a bit of such an experiance in this semester first with 'Bulls N Bears' and then with the compiler lab. Now I am looking forward to the mini project.Want to make it great.

I have already made up mind on the tpoic for the next post. Well its heading is going to be
"Falling in love with Segmentation Fault ".

Thats for now

Another miss!!!!

As i was writing the previous post, another surprise was being taken.As usual I missed that too....
Most of my friends were on their beds..But all of them received smses, informing that exams were going on.Many ran to the class,after wearing the dress.And the remaining joined my company.

Hats off to all those who missed the test

S5 Rocks..........

So here comes a post after a really long period....there were several occasions before when I started to put a post..I signed in to blogger quite a few times.But,each and every time I dropped out at the last minute.Well,it is not because that I did not have anything to say.In fact the semester(S6) was quite eventful in many respects.I have this dirty habit of allowing silly thoughts and matters to eat my brain,and that has been pulling me back.Its time to take another Art of living course, I suppose.

I wish to write about Bulls And Bears, the online stock market simulation game conducted as a part of tathva08.I wish to start it "Right from the beginning ",when the idea flashed through my mind,to develop a software for the same.And I am afraid that a post on it will be quite big,and that's the reason I had been postponing it.Any way it will be put up in a month or so.

The other memorable happenings of this semester is that I failed for the first time in an exam . It was "the design and analysis of algorithm" paper which trapped me before the wicket.And that too,not once but twice.Happy going...

Perhaps the biggest advantage of this semester is that the teachers have stopped taking attendance.And bunking are at its peak.Everyone (I mean ,the Arrakkapodi boys),Usually goes for 2 or3 classes and bunks the remaining 12 or 13 classes in a week.So it is happy sleeping here.While I write this post,it is 11.50 am IST,the fourth hour networks class is going on, and I am sure that at least 5 of my friends will be still on their beds.Well I cant express this particular feeling.Great and simply great teachers! Long live NITC Compsci Dept.

This post is dedicated to all wonderful faculties of Compsci dept who have stopped taking attendance.

but not going as the way i thougt...Any way its not time to complain.I should concentrate on getting it up.


PS: I changed the address.reason?Well,I don't know.

Happy VISHU

I simply want to say A happy vishu to one and all.....

awaitin Ragam

Its the end of yet another exam season. We had two SESSIONALS in a span of four weeks..And that was a bit demanding..
Could perform well on most of the subjects except CO..Now the march towards Ragam 08 begins..I am afraid that it won't be having the vigor and energy of that of last year,but still it is Ragam and it guaranties something.

The exams have been eating my head for the last one month . It's a great relief now.Now should start to learn something . May be PHP or something else.Also I plan to make an entry into online trading. But have to learn a bit more so as to shine in this bear run..

Thats all for now

Chicken Pox rocks at NITC

Never in my life have I tasted chicken...But still I got Chicken pox.(How come?)..Well I don't know...Most of the students in my class was havingan experinxce of it..I was a bit afraid of it...So didn't dare to take any chance and hence soon ran to homeEverything was fine, And I was abt to step out to college..Alas a kuru on my face detected by Amma,Confirmed that I have been infected..Soon sentenced to 2 weeks room imprisonment...Things were not different in the college..More and more students wre being affected and it was decided to shut the college for 2 weeks...Thank god I need not worry abt the medical certificate and othe hulaballas...Homeopothy treatment...Fruits at alternate intervals..everything fine but can't bear the usual food served without any salt...well that is the most horrible part ,I suppose..Advices poured in from all walks of life..People with and without any experiance of it started to dictate the fundas...Each phone call mad amma more and more tensed..
Amma had a real tough time...She was worried abt it spreading to muthassan who is bed ridden.She took 2 weeks leave...and was there ready to execute my orders...I know that she was doing everything posssible from her part...But ocassionaly I used to pour my wrath on her, for there was no one else to shout.
This post dedicated to her, for her wonderful company during those hard days...

CNN IBN INDIAN OF THE YEAR

Sreedharan received CNN IBN INDIAN OF THE YEAR...
Kudos to him..Sreedharan ,One of the most inspiring lives of contemporaryIndian society..In the rank of people like APJ, Mother teresa,Manmohan Singh etc..
His name used to figure in various rankings of different magazines..Has made to the TIME'S list ,also a ususal name in India Today 50 powerful people...
Well what does it really signifies?
First of all it is really a morale booster for all those who have dedicated their lives forpublic service .Of course their selfless mind may not be longing for any recognition..But it is important to make them feel that INDIA really cares them..In a country where bollywood and cricket stars are worshipped near to GOD and wherePublic service is totally out of the lime light,such acts ,such awards, are badly required.It may not be making any difference in those people, who will certainly above such awards,but it inspires the Indian Youth to follow their foot steps.Also it may help them to think out ofblind star worship.
We certainly need Film stars and Cricket stars..But what is their service to the country..Apart from filling thier pockets , how do they make the difference in the society..Perhaps theyentertain us for a few hours..But is that sufficient to have a demi god status?I remeberwhen there was a case in the Delhi High court, lawyers of BCCI pleading that INDIAN cricket teamisa private body, with its own private business and has nothing to do with the country..I wonder if at all a situation occurs, in which the Govt decides to float its own cricketing team and use the revenue from it to eradicate poverty, how many Sachins Or Gangulies will be there to resignfrom BCCI and play for the country. Certainly they say that they play for the country,but is it for thecountry? or for personal monetary benefits and fame, One is not sure.Of course among them tehre will be people who might be doing social service, but that is only a part time business andcertainly comes only after the case of those who have dedicated their lives for the cause of others.
Personally , Sreedharan Sir is a great source of inspiration for me. May be because of the reason that he is a malluHe is a wonder to me , for that he works even at his 76th year(if I am correct)..His secrets..Yoga
I salute PADMAVIBUSHAN Shri SREEDHARAN and wish If we had more sreedharans...

Inspiring Inspiron!!!!!!!!!!!!!!!!!!!!!!!!!!

There is a lot to write and I wonder where to start from….

As I had posted earlier, I’ve decided to buy a dell Inspiron notebook which costs something around 44k. I think dell’s policy of direct to customer will save a good amount. First u need not pay the commission that the dealers will charge you ,also there is no VAT which will save you some 2K.Altogether I suppose that it is a good deal, only that I will have to wait for some 3 more weeks. No problem. Quality comes with a price. It is somewhat a high end configuration. Dual (2) core of 2.GHz, 2 GB RAM, 2MB cache, 2Mega Pixel web cam (ya its all twos. Perfect coincidence.160GB hard disk) .Only that I will have to bear (both the cost and low performance) of Windows Vista. I tried to get a Linux version, not that I would use a pirated version, I simply don’t need. If it was an XP, I would not have minded. But Vista is horrible, I suppose. May be with 2 GB ram I can manage (and perhaps enjoy the aero experience.)


Well the need of laptop at NITC is something that I wish to write in detail. Why I decided to buy one upon a “blade loan”. Well I don’t venture to write on it. It is perhaps a complex issue. Only that, I will have to be more disciplined to make the best use of it. NITC is a place where I have noticed myself being described as “Bagyavan” upon telling that I don’t have a laptop. That’s the way things go here…..

Half naked fakir!!!!!!!

Thats what I felt, sitting near the operation theater waiting for my turn to get inside the 'STERILE AREA' for the first time in my life.I had a growth on my lymph node which I decided to operate. It was at Daya hospital Thrisur that I ended up. Two words abt the hospital;;;Good bulding, moderate rates, Good doctors but extremely poor system and extremely poor nurses. Thats my first hand feel abt it. No where else, I suppose, u would find a doctor attending the share holders meeting when he has got a lot of patients waiting outside for his 'Darsahn'. And the villian of the story is Dr Abdul Aziz. I can't help writing abt him, as the desperation I felt ,on having to wait for 3 hrs after getting a token no 3, is quite inexpressible.I will have to go there one more time but certainly I won't dare again.

Happy New Year to one and all...
HAven't been blogging for quite sometime..Busy playing badminton..great game .should have started earlier..

S4 rocks...truely rocks...The much awaited time has come...NO labs with physical work.ONly the work before the computer.Has got to learn a lot.
Wishing to host a virtual stock market for tathva 08. Started learning PHP..great learning experience..

I am planning to take a lap top.Most probably that of DELL Inspiron...Everything is good except the delivery system.Siraj is having a real mess out there to get the laptop .His has been a wait of more than one month.
Is this the customer care of such an international brand.Extremely shameful....
