New Year's Resolution




What is New Year's resolution?


A New Year's Resolution is a commitment that an individual makes to a project or the reforming of a habit, often a lifestyle change that is generally interpreted as advantageous. The name comes from the fact that these commitments normally go into effect on New Year's Day and remain until fulfilled or abandoned. More socio-centric examples include resolutions to donate to the poor more often, to become more assertive, or to become more economically or environmentally responsible. People may act similarly during the Christian fasting period of Lent, though the motive behind this holiday is more of sacrifice than of responsibility. The new year resolution is one example of the rolling forecast-method of planning. According to this method, plans are established at regular short or medium-term time intervals, when only a rough long-term plan exists.

There are religious parallels to this secular tradition. For example, in Judaism's holiest holiday, Yom Kippur, one is to reflect upon one's wrongdoings over the year and both seek and offer forgiveness. The concept, regardless of creed, is to reflect upon self-improvement annually.

Timeline of computer security hacker history

This is a timeline of computer security hacker history. Hacking and system cracking appeared with the first electronic computers. Below are some important events in the history of hacking and cracking.


Read More......

Hacker (computer security)

In common usage, hacker is generic term for a computer criminal, often with a specific specialty in computer intrusion. While other definitions peculiar to the computer enthusiast community exist, they are rarely used in mainstream context. Computer hacking subculture is often referred to as the network hacker subculture or simply the computer underground. to its adherents, cultural values center around the idea of creative and extraordinary computer usage. Proponents claim to be motivated by artistic and political ends, but are often unconcerned about the use of criminal means to achieve them.

Paul A Taylor defines a hack as being simple but impressive; involving sophisticated technical knowledge; and having the illicitness of being against the rules.

Software cracking

Software cracking is the modification of software to remove protection methods: copy prevention, trial/demo version, serial number, hardware key, CD check or software annoyances like nag screens and adware.

The distribution and use of cracked copies is illegal in almost every developed country. There have been many lawsuits over cracking software, but most have been to do with the distribution of the duplicated product rather than the process of defeating the protection, due to the difficulty of constructing legally sound proof of individual guilt in the latter instance. In the United States, the passing of the Digital Millennium Copyright Act (DMCA) legislation made software cracking, as well as the distribution of information which enables software cracking, illegal. However, the law has hardly been tested in the U.S. judiciary in cases of reverse engineering for personal use only. The European Union passed the European Union Copyright Directive in May 2001, making software copyright infringement illegal in member states once national legislation has been enacted pursuant to the directive.

Juniors : {for spare time reading!}

part 1: interaction

i dont know whether i should write it or not, or is it too early to write this?? but i must appreciate the juniors.
like each other years, the batch is a mix of some goods and some "not so goods", but i seem to have interacted with the goodones only... the first day itself, i had interacted with 7 odd freshers, of which i remember the CSE- ukra guy very nicely, one guy is supposed to have come from CP, and knows me from my target batch days... although i dont remember him. i met his friend, arvinds bro, and 3 more guys out there... i was missing the smart,decent,confident and quality junior... finally i came to know such a junior (shouvik, ME) the very next day! i was a bit rude, and he afraid. i dont know why he was afraid of me that time, may be, my being a senior was reason enough for him to stay away. he was the first to have approached me, thinking me to be a fresher! LOL, i was trying to execute some "second year" stuff, like asking him to introduce himself and stuff, but he seemed innocent, and me confused! he seemed mannered and didnt lack confidence. i actually liked him - a sharp junior material. but as i started to explain to him , how to introduce himself... the 3rd year seniors came and did a thoda-bohut [thoda for them.... bohut for the junior] ragging. i remember the guy with shouvik, he was arrogant, but i didnt tell him anything for he was sick !
anyways.. i found in shouvik the right proportions of confidence and decency and a perfect brother type guy! i donot expect him to lie to me! if he does and if he is caught... God save him! i cooled him down a bit, and enjoyed all the way to kolkata, where i really felt good, interacting with a junior,.. i dont know what he felt!
(may be - what a senior re bhai!! instead of ragigng me... talking as if he is a friend!!?? )
any how , he now shares a bros' place in my heart!
after him, i met his roomie and his friends.. hehehe
i just walked into the first years canteen ( which i was not supposed to do by any means), and sir also didnt check me... and before that i had a talk with a dozen of juniors or even more than that... and i loved it! i corrected them, took their "chota" intros . the most significant of them were the two CSE juniors and harsh gupta , another CSE junior... who smiles at everybody...
let me meet him someday... i am sure to make him smile for an hour!!LOL. in the canteen , i met some more of my juniors... a total interaction, talked freely with all, and answering their innumerable questions.. oh God... where do they bring these questions from??
anyways... i managed to find a couple of "not so good" juniors, sort of scolded them.. but finally escorted to the college, skipping my lunch.
the next instance, i was taken back by a surprise!!
a girl (girls are supposed to epitome of discipline and manners... right??) pointing finger at me, saying "excuse me!! where is the EC101 lab??".. i couldnt help but be rude!
i scolded her a bit ( i couldnt get more rude!!), but finally showed her team (15 girls perhaps or more) the lab. the teacher there, didnt mind the scolding and supported me there.
that day also, i met some new faces... some good, but not as good as shouvik... but were good. they lacked confidence..
the junior from CSE - anjani kr mishra... he lacks something... i dont know what.. but lacks something, he said "yes bhaiya" a million times... after i completed each of my statements..
that irritated me..
yuvraj- as his friends call him..[i again forgot his real name] is good... but i think it is tough for him to accept me as his senior , i can understand.. he is older to me by age.. so i dont expect much much respect from him... but yes - i do expect decency from him...
with him , came another fresh face, arrogant, irritating, nonsense stuff..sure to be blacklisted!
i forgave him, when he said sorry [he had the audacity to call me and say "sorry".... aami arr ki korbo... kore dilam... forgive!! bollam "first nonsense is always forgiven..."]
oh ha!! yesterday, i met a kid!! a first year kid(debashis charavarty)... who speaks much,,, i mean very much.,. too much ... a bit too very much though... onek khon por aamar matha ta byatha korte legechilo...
even sei raat e aami sei bok bok - e ghumeo shunte pachilam!!
ekhon oke dekhlei hashi paaye. i lend him my shoes though... and that evening, i stood there talking to one junior or the other for about an hour!!
in the independence show also, i met many freshers.. of the notables is jahangir alam, (again from mechanical department), who was confident, and has qualities of becoming an anchor (ototao confidence nei...)[i felt the need of a good anchor... may be the anchor there was pathetic!] and another guy, from pharma. who took my phone number.
{it is sad that almost all juniors i have interacted with are guys... i wanna see more junior girls , decent, confident, quality freshers to interact with me}
later today i met 2 juniors. ... obese.. not so confident, pampered.. pathetic... they need their parents to take them home?? yack!!
and both of them are supposed to be from respectable disciplines!! one was from ECE while the more pampered one from CSE!!
yeh junior ke chakkar mein, i also interacted with many of my seniors,,,... with whom i never felt the need of interacting before.
but they were also good,... in short - my juniors are making me feel more responsible, and i am starting to enjoy myself at college!
kudos to shouvik,avik, "yuvraj", the talkative debashis, the over simplified - bidhan for making me feel responsible and feel like a "grown up"!!

arrlekha uchit hobe na! 'freshers hoye jak tarpor lekha jaabe,,,
i am supposed to write a testimonial for shouvik... after he writes it for me.. hehehe..lets see..




part 2: expectations


see, we all seniors look for certain traits in our juniors. what do i want??
what exact traits in juniors/freshers am i searching for??
am i searching for a flamboyant new face who will bunk classes and do sort of dada giri??
or am i searching for a fully oiled hair guy who is a book worm? or a person shy enough??
at first i was confused... the kinda moody person i am, i love each trait at some point of thetime or other... in my class also.. sometimes i really appreciate nupur mallik for her consistency, ashish for his flamboyancy [but no dadagiri], avinash for he oversmart attitude... debashis/DD for their simplicity, aninya for her didigiri,, anindo for his precision, abir for his intellect... kashinath, priyojit for their "no care in life" attitude.. priyonkor and monodeep for their respective ambitions, arvind for his constant improvement, nilima for her commitment towards studies and the class..salauddin for his "simple on face" expressions,, priyank for his attitude [which sometimes appears very stupid to me depending on my mood][but it isnt actually].... mrinal for his confidence... but all these trait apart, what am i searching in a junior?

well... someone like no other,, someone who will never lie to me, however rude or hurting it is... will speak the truth to me, share feelings, listen to me.. decent, confident, a guy/gal who talks,shyness element ektu [seriously ektu] thaka uchit, who knows how to keep the balance between decency and confidence, and ha!! reliable.

emon jeno na hoye, je beshi confidence dekhalo, attitude dekhalo, mithya bollo.... erokom hole jani na ki korbo... aami ekhono lier der ke parle merei feli... i really do feel je... liers shoudnt stay on this face of earth,... any ways..lets proceed with the topic.
jeno beshi lojja na paaye. if he/she is very very shy.. then its problem!!
should have enough confidence, not to fumble infront of a senior....
[matha ki bhabe thanda rakhte hoye... seta ami oder ke shikhiye debo!!]
the one who talks,,,emon jeno na hoye.. je i take him/her out for a treat and we spend the time with dumb mouths!grrr... i think i have enough explained it... i cannot more explain it.
basically bhai/bahen type!
a one who doesnt find wishing seniors - detrimental to their self esteem, should have an attitude but mustnt have a problem with it! i mean should use the attitude in the right ways!
it shouldnt come in between while talking with a friend or a senior!

i think these are the basic requirements of becoming a good junior!! LOL
was i one ??

na apatoto arr kichoo chaina..
they are the juniors now, and after 1 year will be the 2nd years... they [we too] are the soul of the college,,,,.... they must be good!
aami ei raate e ki shob aaje baaje post korchi!!



part 3: ragging - the gandhian way

do anyone here feel that ragging is necessary??
or does all feel that it is evil??
or the diplimats here would definitely feel ragging to be "necessary-evil"!!\

but i feel, physical ragging should be stayed away from and never should be resorted to.
arr emniteo aamader college e jaa hoye... that is light years away from being physical...
ha... aamader senior gulo aamader kichoo irritating questions korto... ja mental ragging bola jetei pare,,, but i am a staunch follower of Mr.M.K.Gandhi....majhe majhe aage saddam hussain type hoye jetam.... but its a rare phenomenon now!

i feel taking intros is enough.... and when ever your juniors go wrong,,... if we correct them, that will be enough....
i have seen, and sorted some of the common problems amongst juniors and have found ahimsic methods to solve it. [taking for granted, that being a senior, they will follow our words]
> speaking less : bhison baaje jinish.... very very condemnable thing... toh this is the punishment : "start talking... talk for the next 5 [or 10] mins , and for each big pause, 5 more minutes will be added... ", by this if he pauses... he needs to speak more... and i am sure he/she will stop... and after a considerable long time... will speak their mind... and that is what i want from the juniors,... to speak their mind.

> speaking more: try the reverse.... but i feel... people look good only when they talk.... so i'll let my juniors talk... talk as much as they can.... [but beware of debashis charavarty]

> attitude: it of various types.. and the most nonviolent thing that can be done .... is something like this:
==> excuse me [without any kind of sir/mam/dada/didi] : make him/her write "x-cuse me!!" for 500 times without a considerable pause... for each pause add 50 times more!
i think he/she will forget excusing themselves...
====> extra smart/irritated looks: just make him/her stand by your side, completely ignoring him/her while you are talking to other juniors...
=========> extra laughing [ the harsh gupta syndrome]: irritates most seniors... [sometimes i get irritated, depending on mood],.... karo mukher hashi kere neoa uchit na.... ekdom na... make him laugh for 5 minutes!
and for each considerable pause... add 5 more minutes to the laughing account!
===============> afraid/frightened: take him/her to the cafeteria or the shop near by... make him/her comfortable by chilled water/or coffee/ or tea... relax him/her...
======> indecency: etar ki korbo... seta niye aami research korchi... eta hole matha khub gorom hoye.... saddam type hoye jai.. kintu ahimsic way khujji...
==========> disrespecting girls: .... sonu nigam er classically mild album er "dhyannya dhaanya naari jivan" gaan ta 50 bar shona.... ba nirupa roy er video dekha... and then ask him/her sing that song or act that way... get the lyrics memorised.... and for each mistake commited after listening to it for 50 times... for each mistake make him/her listen to the song 5 more times!

apatoto etotai thak... baki ta aaro research kore likhe debo//

● Research in Nanotechnology

The reaseraches in nanotechnology can be studied under 4 heads, they are the current forms of researches and the information regarding them is gathered from wikipedia, in this blog I have discussed only about the nanomaterials, the information regarding the other heads will be published soon.
A)NANOMATERIALS:
This includes subfields which develop or study materials having unique properties arising from their nanoscale dimensions.
interface and colloidal science has given the idea of many substances which can be successfully applied to the field of nanotechnology such as carbon nanotubes and other fullerenes apart from various naoparticles and nanorods.
nanoscale materials can also be applied in case of bulk applications, the most recent commercial applications of nanotechnology are currently dealing with this aspect.Nanomedicines are an important application of such materials.Its aspects will soon be shown in this blog.
There are many terms used there where certain terms will seem alien to all of my age, so all those terms need proper explanation, they are described below:

1.INTERFEACE AND COLLOIDAL SCIENCE:they are a branch of chemistry dealing with colloids, heterogeneous systems which constitute particles whcih are in a mechanical mixture and has dimensions ranging from 1nm to 100nm and remains dispersed in a continuous dispersive medium.
2.CARBON NANOTUBES: they are the allotropes of carbon, that have nanostructure and whose length to diameter ratio is about 1000000.they are cylindrical carbon molecules that possess certain properties which make them useful applications in the field of nanotechnology, electronics and other branhces of material science. they also find useful applications in the fields of architecture. they have extraordinary strength and are excellent conductors of heat and electricity.inorganic nanotubes presently have also been synthesized
3.FULLERENES: although this term is familiar to everybody , but I still need to have some concepts clarified. they are the allotropes of carbon that are composed of carbon molecules which are arranged in a hollow sphere, ellipsoid, tube or plain like structure
4.NANOPARTICLES: particles which behave as a whole unit in terms of its property and transport, their size remains between 1-100nm.they belong to the clan of ultrafine particles and their size can be restricted to 2 dimensions , as told once they may or may not show size related intensive properties as shown by fine particles (100-250 nm) or bulk particles.
5..NANORODS:they are one type of nanoparticles that have length is to width ratio 3-5. they can be synthesised by direct chemical synthesis.

6.NANOMEDICINES: this topic needs a lot of discussion, but it done shortly here.it involves the medical application of nanotechnology involving medical uses of nanomaterials, nanoelectronic biosensors and some future applications of molecular nanotechnolgy( this topic will be discussed in details in some other blogs following this).nanomedicine seeks to deliver a variety of reasearch tools and some clinically beneficial devices in the near future.the nanomedicine research is directly funded by the US NATIONAL INSTITUTES OF HEALTH in 2005 following a 5 year plan , to set up 4 nanomedicine centres. according to the information published in NATURE JOURNAL in april 2006, about 130 nano-bsed drugs and delivery systems are being developed world wide. Nanomedicine is a large industry, with nanomedicine sales reaching 6.8 billion dollars in 2004, and with over 200 companies and 38 products worldwide, a minimum of 3.8 billion dollars in nanotechnology R&D is being invested every year. As the nanomedicine industry continues to grow, it is expected to have a significant impact on the economy.the medical uses of nanomaterials are: a]drug delivery, b] cancer treatment, c]surgery,d]visualization,e]nanoparticle targeting..etc.
It is greatly observed that nanoparticles are promising tools for the advancement of drug delivery,medical imaging and as diagonostic sensors.. However, the biodistribution of these nanoparticles is mostly unknown due to the difficulty in targeting specific organs in the body. Current research in the excretory systems of mice, however, shows the ability of gold composites to selectively target certain organs based on their size and charge. These composites are encapsulated by a dendrimer and assigned a specific charge and size. Positively-charged gold nanoparticles were found to enter the kidneys while negatively-charged gold nanoparticles remained in the liver and spleen. It is suggested that the positive surface charge of the nanoparticle decreases the rate of osponization of nanoparticles in the liver, thus affecting the excretory pathway. Even at a relatively small size of 5nm , though, these particles can become compartmentalized in the peripheral tissues, and will therefore accumulate in the body over time. While advancement of research proves that targeting and distribution can be augmented by nanoparticles, the dangers of nanotoxicity become an important next step in further understanding of their medical uses..

● Presidential form of Goverment in India?

The idea of a change in system of governance may seem preposterous but I have given it a serious thought before writing this blog. All the problems that the present government is facing are due to our system. The days of single party majority are gone and chances of it coming back, in the near future is remote. In the last two decades we have formed innumerable rag tag coalitions, which have hurt the Indian Democracy badly. Today the governments in power need to depend and give in to the whims and fancies of some king makers. The governments concentrate more on keeping themselves in power rather than on good governance. That’s the basic problem that we face today. We need to revamp this system in to more efficient one and for that wee need a Presidential form of government.

Two great and efficient democracies follow two kinds of Presidential form of governments, Russia and United States of America. I will prefer the latter but the Russian one will suite us better.

The Russian system is such that various steps are completed before a President is elected. First a lot of candidates throw their name into the gauntlet and elections take place. The two candidates that secure the highest number votes then contest the election.

How will it work in the Indian system? The so called ‘netas’ will file their nomination papers with at least ten parliamentarians forwarding it. Due to the fragmented nature of our country no one will secure fifty one percent votes in the first stage. So the two best candidates move on to the second round. The losers will then throw their weight on the candidate of their choice. Finally we will have our own President.

Does such a system not automatically favour candidates from the more populous states? one may ask. Is there any chance that someone from Manipur or Lakshadweep will ever win the votes of a majority of the country's voters? Could a Muslim or a Dalit be elected president? These are fair questions, but the answer surely is that their chances would be no better, and no worse, than they are under our present system. Seven of India's first 11 prime ministers, after all, came from Uttar Pradesh, which surely has no monopoly on political wisdom; perhaps a similar proportion of our directly-elected presidents will be UPites as well. How does it matter? Most democratic systems tend to favour majorities; it is no accident that every president of the United States has been a white male Christian (and all bar one a Protestant), or that only one Welshman has been prime minister of Great Britain. But i dare say that the need to appeal to the rest of the country will oblige a would-be president from UP to reach across the boundaries of region, language, caste and religion, whereas in our present parliamentary system a politician elected in his constituency on the basis of precisely such parochial appeals can jockey his way to the prime ministership. A directly-elected president will, by definition, have to be far more of a national figure than a prime minister who owes his position to a handful of political king-makers in a coalition card-deal. I would also borrow from the US the idea of an electoral college, to ensure that our less populous states are not ignored by the candidates: the winner would also be required to carry a majority of states, so that crushing numbers in the cow belt alone would not be enough.

Why should we underestimate the wisdom of the Indian Electorate? Jamaica with a 97% black population elected a white president. In Argentina a country that is proud of its European origins twice elected, son of Syrian immigrants, Carlos Saul Menem. Peru elected a Japanese origin President in Alberto Fujimori. Indeed, the voters of Guyana, a country that is 50% Indian and 47% black, elected as president a white American Jewish woman, who happened to be the widow of the nationalist hero Cheddi Jagan. A story with a certain ring of plausibility in India.

The adoption of a presidential system will send our politicians scurrying back to the drawing boards. Politicians of all faiths across India have sought to mobilise voters by appealing to narrow identities; by seeking votes in the name of religion, caste and region, they have urged voters to define themselves on these lines. Under our parliamentary system, we are more and more defined by our narrow particulars, and it has become more important to be a Muslim, a Bodo or a Yadav than to be an Indian. Our politics have created a discourse in which the clamour goes up for Assam for the Assamese, Jharkhand for the Jharkhandis, Maharashtra for the Maharashtrians. A presidential system will oblige candidates to renew the demand for an India for the Indians.

Any politician with aspirations to rule India as president will have to win the support of people beyond his home turf; he will have to reach out to other groups, other interests, other minorities. In that may lie the presidential system's ultimate vindication

● Advent of Nano-technology and Industrial revlution

Nanotechnology is not an individual science or technology. It is a uniting expression for the multi-disciplinary area of production technologies operating in the area of extremely small size particles and materials starting from individual atoms and molecules. Hundreds of products involving nanotechnology are already available and the future applications seem endless in the areas such as biomedicine, computers, consumer products and energy.
So far we have heard of coatings like non-stick pans, self-cleaning window panes, non-scratching paint and sun-screens. In the future we may encounter medical devices which could possibly travel in the human body and cure disease at the cell-level and nanorobots capable of self-assembly
WHAT EXACTLY IS NANOTECHNOLOGY?
A nanometre is one millionth of a millimetre. One human hair is about 100.000 nm thick. Generally when discussing nanotechnology it is defined as handling research and technology in the area between 1 and 100 nanometres the aim of which is to created materials with new properties and functions associated with the small size.The idea of nanotechnology is not new. Richard Feynman’s speech “There’s Plenty of Room at the Bottom” at Caltech in 1959 suggested that the direct manipulation of individual atoms is a more powerful form of synthetic chemistry. The invention of the scanning tunnelling microscope in 1981 by Gerd Binnig and Heinrich Rohrer from IBM, has in particular led to expanding research and the development of the first commercial products in the late 1990s. The inventors received the Nobel Prize in Physics for their work in 1986.Nanosize materials appear in some forms naturally as viruses or particles in volcanic ash. Some particles are produced by human activities like diesel exhaust and other combustion processes. It has been estimated that 50.000 kg/year of nanosized materials are being produced through these unintentional processes. There are negative impacts on people’s health especially in regards to causing respiratory diseases. However, the research results are not yet comprehensive.


The nanotechnology research aims at creating totally new materials not available anywhere before. The characteristics of nanomaterials can be surprisingly different from the same materials in their traditional form. This is because in nanosize the laws of quantum physics and not of classical physics are valid. Insulating materials may become electrically conductive and insoluble materials soluble. In addition, features such as hardness and durability may increase dramatically making these materials excellent for lightweight structures. Many of these characteristics are highly desirable for various products. One feature of the materials is that the smaller the particle gets, the higher the surface area is to the volume ratio. This means that the material gets more reactive with other materials. The feature can be used for example in medical applications, but it may also pose new health risks.
Nanotechnology has been welcomed with enthusiasm for all the promises it holds. Some of the predictions seem to be pure science fiction – like the idea of self-replicating nanomachines getting loose and changing all living material into “grey goo”. But even the already known applications are often surprising and they are pushing the limits of the human imagination.

.RISKS & RISK MANAGEMENT

When considering the wide scope of applications and the strong impact expected on economies it is easy to say that there are great variations in the associated risks as well. In addition to the business risks, risks related to intellectual property and the political risks the main concern at this stage are the risks related to human health. We do not yet know whether the nanomaterials are harmful to people. The nanoparticles can enter a human body through inhalation, ingestion or directly through the skin and they can accumulate in the body. It is possible that they travel through cell walls. Their toxicity or carcinogenic properties have not yet been comprehensively researched. As the production volumes are still small, the exposure is not yet major. In most of the applications the particles are included in other materials thus decreasing the possibility of direct exposure. The first area where we might find evidence of harmful effects is in occupational health and safety. Even if the nanomaterials as such are not more dangerous than any other substances, all their health impacts are not yet known. There have been extensive investments in the research of the health impacts simultaneously with the practical solutions of the new technology being introduced.But the liability and recall risks will also increase as the development progresses. Products will end up with the final consumer. If the still unrecognised health impacts only manifest themselves after long term use of the products by numerous consumers, the liability could theoretically accumulate to catastrophic dimensions. The danger of illnesses comparable to those related to asbestos is considered improbable. However, it is important to approach the potential of a massive risk seriously in advance, even if it is seen as theoretical.Another area of still unknown risks is the environment. What are the possibilities of the materials ending up in the environment and causing irreparable damage? How will the waste disposal of the used products be handled? The nanomaterials may not be biodegradable in the same way as larger scale materials. They may interact with other substances and accumulate in nature. But at the same time there are tests being carried out studying the use of some nanoparticles to detoxify the environment from for example PCB or chlorine and the use of nanotech sensors to monitor environmental status.
Nanotechnology is an enabling technology offering new possibilities to many existing industries and products. This means that all industries are affected through it and have to respond to the risk management challenges. The risk management is not straightforward as there is not any singular “nanorisk” to manage. At the moment there is no available terminology, standards, measuring methods or agreed risk management tools for the special risks associated with nanotechnology.

● Objective type or subjective type.Have your say?

There is a never ending debate on whether objective type question is better or subjective type.I personally feel that objective type question has a edge over subjective type.The reasons are
1.In all the major institute like iit’s we have objective type paper.
2.In the entrance examination for post graduate courses like CAT we have objective paper so in order perform well in these all India examinations we must practice objectives.
3.In the technical section of campus interview companies set objective type paper.
For example tech mahindra in their techinal exam at heritage institute of technology gave
100 ojective to solve in 1 hour.so without prior practice it is impossible to solve so many questions in so short time.
4.most importantly if the question pattern is objective type then there is no scope for suggestion,student is compelled to go through the entire syllabus.
5.students often complain that there marks vary as different teachers give different marks on same answer.so by switching to objectives we also eliminate this problem.

In this context by objective I in no way mean mcq with one option correct.by objective I mean mcq with more than 1 option correct,assertion-reasoning,matrix match,short answer type question etc.By going for these options we also minimize the chances of guess work.
I know many of you think alike or otherwise.
Please let us know what u feel regarding this
matter.

● Are We Employable? - part 1

Now that employability is the buzz word currently doing the rounds in academic arenas... arent we supposed to counsel ourself and ask to ourself this very simple question.... Are we employable?....Read the full article

● Can we determine the value of infinity?

Our Maths teacher used to say, you can determine the value of infinity if you have a reference. Say, you are standing in front of a parallel railway track. It seems that they

rail lines are meeting each other. He says, that point is infinity with respect to you. (Parallel lines meet at an infinite distance)
Now the question is...Can we really determine the value of Infinity?
By definition, parallel lines are always same distance apart, no matter what. This is math, not physics, and definition, not theory or theorem. Thus, they do not.
The railway lines are (optical) illusion, based on physics, not math. Although true, the do look to be closer is valid. Also a highway going straight for long distance will appear to have sides meet, to where it shrinks to a point. That is optics. Physics. Not math. Perhaps teacher was goading students for such reply (get you grade of A+ ??).
A more modern view of some, is more relevant to the infinity term. A line (or more) going on for ever and ever -- (if it had a beginning) will meet itself over that infinite distance. Thus if you got on that highway, and travelled straight forever, you'd eventually arrive at the place you began. What a stretch, huh? I think this one, while sounding more like physics than math, began a century or more ago inside concept of non-euclidian geometry (math) or curved_space (now astrophysics?). If any continuing interest, you might want to try those on as search terms.

1. You can never determine the value of infinity because the term intrinsically has no numeric value or maximum.
2. If the lines are parallel then they are parallel, whether you measure them after one yard, one mile or any distance then they must remain separated by the same distance. That is what parallel means.

3. The apparent meeting of the lines at a distance is an optical illusion and has nothing to do with their mathematical relationship to each other.
4. If you can accept that the term infinity means 'never ending' then the lines will never meet.
Infinity can simply be beyond the limit of our understanding. If we take a child who has never left their village, then infinity can be as far as the next village. If we take a man who has never left his country, then infinity can be the next country. This may not be an entirely accurate description of infinity, but it does fit to a degree.
We consider that a modern explanation of infinity to be further than the furthest star. Basically up and out. The "outside". But today we know now that we will know more tomorrow. So what ever label, description, idea, measurement or theory we assign to the term "infinity" WILL, one day, be exceeded.
What else?
"To infinity, and beyond!" (Buzz Light year).
This sort of supports my idea that infinity is a boundary that is constantly moving. We have beliefs in what we cannot know and theories and proofs to support what we do know. Is infinity just another belief system yet to be defiled by proof? Buzz has faith in his abilities when he is only (and I apologize for the spoiler) a toy.
Infinity is simply a boundary of our own imagination. A much harder term, I feel, is "forever". Time vs distance?
To put the discussion on a scientific basis, the concept of infinity stems from that of innumerability. That is, whatever we are discussing, angles, equations, distances, and so on, we equate each of our "objects" with an integer number. When we run out of numbers for our counting we talk of an enumerable quantity. This is on first consideration, infinite. But if we try counting real numbers (those with decimal places) by association with integers we discover that there are more reals than integers. This is a second infinity which is not equal to the first.
It was Gregor Cantor who investigated these things at the turn of the twentieth century.
So, I'd go back to your maths master and ask him, which infinity he is talking about!
These two definitions of infinity were first proposed by Aristotle. He called the first one (running out of numbers to count) the infinity in length and the second one (infinity in decimal places) infinity in divisions.
As we are talking about parallel lines meeting at infinity, we ar talking about infinity in length.
In a more practical way, any finite number can be considered to be infinite if it is much greater than another one which you are comparing. For example, when calculating the orbits of small planets, such as the earth, you may consider that the sun is at a fixed point and doesn't move because it has such a great mass compared to earth. But this would only be totally true if the sun had infinite mass. So you can say, as an approximation, that the sun has infinite mass compared to earth. This kind of approximation is very useful in physics, and yields good results if used correctly.
This approximation is what your teacher used when he talked about the rail tracks. The distance between the tracks (lets say, 1 meter) is much smaller then the length of the rail track (100's of kilometers). So when you try to see the whole track, due to the change of scale, they seem to be together, because its length is much greater than the the width. When you are close to the track (lets say 2 meters close) you can see they are not connected. But if you look far away (10 kilometers) the width is so small that you cant resolve the two tracks anymore.
The rail track infinity is an approximate infinity. It is an open question today for physicists if real infinities do happen in nature. General relativity and quantum mechanics predict the existence of such true infinities (sometimes called singularities). But its not clear if they really exist of if they are a flaw in the theory. Anyway, physicists must work their way around them, since you cant make calculations or measurements with infinite values.

● e-books: Data Structures and Algorithms

So finally......Here are the links to some of the most wanted books n engineering colleges..Currently I am only uploading the link to Data Structures and Algorithms by Alfred V. Aho, John E. Hopcroft, Jeffrey D. Ullman. Its a rar. So you need to extract it via Winrar. The files in it open by Mozilla Firefox. I don't know whether it opens without Firefox or not but feel free to experiment.Just copy paste the url in your browser.It will take to you a page. See on the right hand side there will be an option which says "Click here open the protected link and download the file."

Just click on there and it will take you to the download page.If bad file please post so that I may rectify it. I will be posting the others soon which includes Digital Design ,Third Edition by Morris Manno. Please if you need any book post the proper name of the book with the author and I will post its link if I get it. Thank you!

Here's the first link:
