3-D ness in ur images!!!

2010-03-09T15:20:00.001-08:00

Now with photoshop u can achieve 3-D ness in ur photos and this is particularly called "out of bound" photos!! in this technique actually we create illusion (try to show which is not there!!!)

so i decided to make one now a slideshow just below is going to show what are the original images n what is the final image.

there are two original images (image 1 and image 2) n one final image image 3..

(note: if any1 wanna create their own then mail me at mohanj184.vit@gmail n i'll send u tutorial!!! )

just graphs

2010-03-06T11:57:00.001-08:00

in ma spare tym i made sum graphs u must watch it!!!

yes yes u can have " 3-D " !!!!

2010-03-05T15:13:00.001-08:00

now i think that majority have watched "AVATAR" n 3-D is going crazy in all minds!!!!
so i came up with a novel, inexpensive, stereoscopic technique for generating 3D images
from cellophane on a liquid crystal displays which are most typically used for a laptop screen.

Stereoscopy requires independent manipulation of the left and right eye views.
Our technique takes advantage of two facts;

a) the first is that the light from the liquid crystal display of either a laptop computer or a camera phone is polarized light !!!(

u don't have to know much abt polarized light!!!)

2, and therefore we can easily manipulate its transmission with a polarizer sheet(cellophane paper!!!).

The second fact is that a cellophane half-waveplate can change the direction of polarization of light. The direction of polarization of one half of the liquid crystal screen was rotated by the cellophane half-waveplate.
Two images displayed with orthogonal polarization on two halves of the screen become separable by wearing a pair of glasses of orthogonal polarization.

so anyone can conver laptop screen into a 3D display with minimal knowledge of optics.

now what is stereoscopic's principle!!! i m gonna tell u by a modal approach which u can see in below image!!!

now u have to achieve this effect in ur laptop with the help of polarized glasses (made up of cellophane paper)

now this is goin to show how????

this is ma polarized goggles!!

inner view of goggles!!!

outer view of goggles!!!

this is my laptop screen!!

Now w@t 2 do for getting 3-D feeling from ur laptop

cover half of ur laptop screen with cellophane paper n make cellophane goggles n just wear n view anything in ur laptop it will appear 3-D!!!

now happy 3-Din!!!!!

bbye c u n take care!!!!! haha!!

(n dear u can get this cellophane paper from any stationary shop n u can make goggles wid help of any cardboard !!! :for vishal!!! )

Practical implementaion with lightScribe technology

2009-12-16T23:22:00.001-08:00

I think everyone knows about this technology in theoritical now in this i m gonna show u practical implementation of this techonology in day 2 day life.

lets start wid some introduction of this:

LightScribe is an optical disc recording technology that uses specially coated recordable CD and DVD media to produce laser-etched labels with text or graphics, as opposed to stick-on labels and printable discs.The purpose of LightScribe is to allow users to create direct-to-disc labels (as opposed to stick-on labels), using their optical disc writer. Special discs and a compatible disc writer are required.

LightScribe was evaluated by Hewlett-Packard engineer Daryl Anderson and brought to market through the joint design efforts of HP's imaging and optical storage divisions in 2004. Anderson is no longer actively associated with Lightscribe.

Now not going to so much practical details about lightScribe lets talk about my purpose to write this blog

today mainly every laptop comes with this techonology of lightScribe in DVD writers. i m also keep hearing from my colleagues that u can also make ur own label CDs/DVDs through this techonolgy so i decided to make one .so especially for this i went to chennai (3 hrs from my location) to buy a lightscribe DVD oh sorry i forget to mention that for this labelling we require a special DVD called as lightScribe u can find it at any computer shop well i got a DVD from imation brand though it costs (Rs. 100) .after this we need a labelling software mainly u can go for acoustica CD label marker don't go for its name it works well for DVD too n its works very fine.now after this u need a image mainly labelling is in sepia (black n white with some yellow version)mode.now i m gonna show my image n label DVD

dats d image

dats d label of DVD

u can see in the image version the text color is blue but in label it is in black n white version means u can label in only black n white version. colour version is under progress from the manufacturer.

now dats cool u can gift to ur girlfriend with ur unique photos labelled or in ur tour CD u can label ur tour photo now thats cool na.......

enjoy..............

downloading url:

http://www.acoustica.com/cd-label-maker/index.htm

u can get a demo version of label marker software from above site or u can search in any torrents......

GOOGLE™ WAVE

2009-10-02T03:00:00.001-07:00

What is it n how it works...

Google is ready with another tool to further entrench its position in the online world. The Internet's numero uno company has just released its new communication platform Google Wave to a select 100,000 users. Billed as one of the most ambitious projects from Google, experts believe that Google Wave has the potential to alter the way we communicate online.
Google unveiled Wave in May this year during I/O event's keynote address. It started as a side project at Google's Australia office. Wave was developed by a small team in Australia, led by brothers Jens and Lars Rasmussen. It the same team of Australian Google engineers who created Google Maps. Presently, some 60 engineers are reportedly working on the application.

what exactly it is:

An online tool for real-time communication and collaboration, Wave aims to combine instant messaging, wiki, email, document handling and social networking features in one package.
It can be both for a conversation and a document in which people can discuss and work together using rich text, videos, photos, maps and multimedia. Wave also makes it very easy to share photos, which can simply be dragged from the desktop onto the Wave platform.

how it works:

Google Wave users can add new participants to a wave at any time either by clicking "Add" on the wave or dragging and dropping a contact from the Contacts pane on the left to the wave.
Similarly, users can add pictures by simply dragging them into the wave. While the images download progressively, the thumbnails of the pictures appear instantly, while the full image is loaded in the background.
There's also an option for Users to make "quiet" conversations with one or two other participants within the actual wave, and these cannot be seen by the other participants unless you want them to.
Spell checker: There's also a spell checker, dubbed Spelly that automatically corrects misspelt text. The gadget can even recognise how a word is supposed to be spelt based on context within the sentence.

how it looks:

Wondering how Google Wave looks? The main interface looks similar to a standard email box with some changes. On the right side of the interface is a box, which shows the conversations, dubbed "waves" by Google.
These real-time conversations can have multiple participants. All participants have the ability to edit the conversation at any time, with every user being able to see a live feed of what every other participant is doing within that feed.
There's a middle box shows that shows the list of conversations which are either in progress or were made in the past. User icons on the left show the individual wave's participants, and the small green badges show users that are online.

its compatibility and support:

Wave will work on all modern browsers. This means, Chrome, Safari (3 and 4), and Firefox 3.5 and up. Yes, Wave will also work with Internet Explorer. Just that IE users will be asked to install ChromeFrame.
Incidentally, Microsoft does not recommend installing this plug-in, claiming it compromises security.
Developer support: While Wave is a product, the larger goal of the project is to make people adopt it as their online communication platform.
For this, Google is going to need third-party developers. Experts believe that Google needs these third-party developers to build stuff on top of Wave.
Some of such applications include Suduko, a Ribbit conference call gadget, a video chat gadget by 6rounds and a trip-planning gadget by Lonely Planet

Wolfram Alpha is Coming -- and It Could be as Important as Google

2009-04-05T19:50:00.001-07:00

Introducing Wolfram Alpha

Stephen Wolfram is building something new -- and it is really impressive and significant. In fact it may be as important for the Web (and the world) as Google, but

for a different purpose. It's not a "Google killer" -- it does something different. It's an "answer engine" rather than a search engine. took a

close look at Wolfram Alpha's capabilities, discussed where it might go, and what it means for the Web, and even the Semantic Web. Stephen has not released

many details of his project publicly yet, so I will respect that and not give a visual description of exactly what I saw. However, he has revealed it a bit in a recent

article, and so below I will give my reactions to what I saw and what I think it means. And from that you should be able to get at least some idea of the power of

this new system.

A Computational Knowledge Engine for the Web

In a nutshell, Wolfram and his team have built what he calls a "computational knowledge engine" for the Web. OK, so what does that really mean? Basically it

means that you can ask it factual questions and it computes answers for you.It doesn't simply return documents that (might) contain the answers, like Google

does, and it isn't just a giant database of knowledge, like the Wikipedia. It doesn't simply parse natural language and then use that to retrieve documents, like

Powerset, for example.Instead, Wolfram Alpha actually computes the answers to a wide range of questions -- like questions that have factual answers such as

"What is the location of Timbuktu?" or "How many protons are in a hydrogen atom?," "What was the average rainfall in Boston last year?," "What is the 307th digit

of Pi?," or "what would 80/20 vision look like?"Think about that for a minute. It computes the answers. Wolfram Alpha doesn't simply contain huge amounts of

manually entered pairs of questions and answers, nor does it search for answers in a database of facts. Instead, it understands and then computes answers to

certain kinds of questions.

(Update: in fact, Wolfram Alpha doesn't merely answer questions, it also helps users to explore knowledge, data and relationships

between things. It can even open up new questions -- the "answers" it provides include computed data or facts, plus relevant diagrams, graphs, and links to other

related questions and sources. It also can be used to ask questions that are new explorations between relationships, data sets or systems of knowledge. It does

not just provides textual answers to questions -- it helps you explore ideas and create new knowledge as well)

How Does it Work?

Wolfram Alpha is a system for computing the answers to questions. To accomplish this it uses built-in models of fields of knowledge, complete with data and

algorithms, that represent real-world knowledge.For example, it contains formal models of much of what we know about science -- massive amounts of data about

various physical laws and properties, as well as data about the physical world.

Based on this you can ask it scientific questions and it can compute the answers for you. Even if it has not been

programmed explicity to answer each question you might ask it.

But science is just one of the domains it knows about -- it also knows about technology, geography, weather, cooking, business, travel, people, music, and more.

It also has a natural language interface for asking it questions. This interface allows you to ask questions in plain language, or even in various forms of abbreviated

notation, and then provides detailed answers.

The vision seems to be to create a system wich can do for formal knowledge (all the formally definable systems, heuristics, algorithms, rules, methods, theorems,

and facts in the world) what search engines have done for informal knowledge (all the text and documents in various forms of media).

How Smart is it and Will it Take Over the World?

Wolfram Alpha is like plugging into a vast electronic brain. It provides extremely impressive and thorough answers to a wide range of questions asked in many

different ways, and it computes answers, it doesn't merely look them up in a big database.

In this respect it is vastly smarter than (and different from) Google. Google simply retrieves documents based on keyword searches. Google doesn't understand

the question or the answer, and doesn't compute answers based on models of various fields of human knowledge.

But as intelligent as it seems, Wolfram Alpha is not HAL 9000, and it wasn't intended to be. It doesn't have a sense of self or opinions or feelings. It's not artificial

intelligence in the sense of being a simulation of a human mind. Instead, it is a system that has been engineered to provide really rich knowledge about human

knowledge -- it's a very powerful calculator that doesn't just work for math problems -- it works for many other kinds of questions that have unambiguous

(computable) answers.There is no risk of Wolfram Alpha becoming too smart, or taking over the world. It's good at answering factual questions; it's a computing

machine, a tool -- not a mind.One of the most surprising aspects of this project is that Wolfram has been able to keep it secret for so long. I say this because it is

a monumental effort (and achievement) and almost absurdly ambitious. The project involves more than a hundred people working in stealth to create a vast

system of reusable, computable knowledge, from terabytes of raw data, statistics, algorithms, data feeds, and expertise. But he appears to have done it, and

kept it quiet for a long time while it was being developed.

Competition

Where Google is a system for FINDING things that we as a civilization collectively publish, Wolfram Alpha is for COMPUTING answers to questions about what we as

a civilization collectively know. It's the next step in the distribution of knowledge and intelligence around the world -- a new leap in the intelligence of our

collective "Global Brain." And like any big next-step, Wolfram Alpha works in a new way -- it computes answers instead of just looking them up.

Wolfram Alpha, at its heart is quite different from a brute force statistical search engine like Google. And it is not going to replace Google -- it is not a general

search engine: You would probably not use Wolfram Alpha to shop for a new car, find blog posts about a topic, or to choose a resort for your honeymoon. It is not

a system that will understand the nuances of what you consider to be the perfect romantic getaway, for example -- there is still no substitute for manual human-

guided search for that. Where it appears to excel is when you want facts about something, or when you need to compute a factual answer to some set of

questions about factual data.

I think the folks at Google will be surprised by Wolfram Alpha, and they will probably want to own it, but not because

it risks cutting into their core search engine traffic. Instead, it will be because it opens up an entirely new field of potential traffic around questions, answers

and computations that you can't do on Google today.

The services that are probably going to be most threatened by a service like Wolfram Alpha are the wikipedia, cyc, Metaweb's Freebase, True knowlege, the start

Project, and natural language search engines (such as Microsoft's upcoming search engine, based perhaps in part on Powerset technology), and other services

that are trying to build comprehensive factual knowledge bases.

Microsoft Live Lab Photosynth

2009-03-31T06:57:00.001-07:00

History

Photosynth is based on Photo Tourism, a research project by University of Washington graduate student Noah Snavely.

Microsoft released a free tech preview version on November 9, 2006. Users could view models generated by Microsoft or the BBC, but not create their own models at that time.Microsoft teamed up with NASA on August 6, 2007 allowing users to preview its Photosynth technology showing the Space Shuttle Endeavour. On August 20, 2007, a preview showing the tiles of Endeavour during the backflip process was made available for viewing.

On August 20, 2008, Microsoft officially released Photosynth to the public, allowing users to upload their images and generate their own Photosynth models.

Photosynth is a software application from Microsoft Live Labs and the University of Washington that analyzes digital photographs and generates a three-dimensional model of the photos and a point cloud of a photographed object. Pattern recognition components compare portions of images to create points, which are then compared to convert the image into a model. Users are able to view and generate their own models using a software tool available for download at the Photosynth website.

Process

The Photosynth technology works in two steps. The first step involves the analysis of multiple photographs taken of the same area. Each photograph is processed using an interest point detection and matching algorithm developed by Microsoft Research which is similar in function to UBC's Scale-invariant feature transform. This process identifies specific features, for example the corner of a window frame or a door handle. Features in one photograph are then compared to and matched with the same features in the other photographs. Thus photographs of the same areas are identified. By analyzing the position of matching features within each photograph, the program can identify which photographs belong on which side of others. By analyzing subtle differences in the relationships between the features (angle, distance, etc.), the program identifies the 3D position of each feature, as well as the position and angle at which each photograph was taken. This process is known scientifically as Bundle adjustment and is commonly used in the field of photogrammetry, with similar products available such asImodeller, D-Sculptor, and Rhinoceros. This first step is extremely computationally intensive, but only has to be performed once on each set of photographs.

The second step involves the display of and navigation through the 3D point cloud of features identified in the first step. This is done with the publicly downloadable Photosynth viewer. The viewer resides on a client computer and maintains a connection to a server that stores the original photographs. It enables a user to, among other things, see any of the photographs from their original vantage point. It incorporates DeepZoom technology Microsoft obtained through its acquisition of Seadragon in January 2006. The Seadragon technology enables smooth zooming into the high-resolution photographs without downloading them to the user's machine.

The Photosynth D3D based viewing software is only available to the Windows Vista and XP operating systems. The team recently released a Silverlight version of the viewer:Photosynth Silverlight Viewer

As of March 2009 user uploaded Photosynth collections are now available for viewing on iPhones using iSynth (3D) or Seadragon Mobile (2D only).Capabilities

Sixth sense technology

2009-03-27T20:07:00.001-07:00

Indian Geek Develops 'Sixth Sense' Device

Use hand gestures to click pictures or send mails

28-year-old Pranav Mistry, a MIT (Massachusetts Institute of Technology) based researcher hailing from Gujarat has created a digital prototype of a "sixth sense" device that is being currently evaluated by corporations including Google, Microsoft, HP and Samsung.

To briefly describe what this sixth sense is all about, we need to understand how the current dissemination of information from current electronic devices takes place. Most of the information from computers, mobile phones and other devices are confined to screen or paper - if we decide to take a print. However, the sixth sense, according to Mistry, bridges this gap "bringing intangible digital information out into the tangible world, and allowing us to interact with this information via natural hand gestures". The concept falls under "wearable computing" -- the same category under which the ubiquitous mobile phone falls as well.

The equipment list for the sixth sense might seem a tad crude, but it does its job quite well. It comprises a pocket projector; mirror and web camera bundled in a wearable pendant-like mobile. With the help of the projector, you can turn any material surface into a touchscreen. The camera is used to "see" the hand gestures. The user will however need to wear color-coded gloves on the index finger and the thumb so that the hand movements can be recorded and decrypted.

Some of the interesting hand gestures include drawing a square frame which will trigger a command to take a picture, drawing the @ sign will let the user access his email. You can even write e-mails with the help of the projector, which projects an image of a virtual keyboard so that you can type. All this costs around $350 (Rs. 17,000) to build - which is not a bad for something as futuristic as this!

Mistry has been approached by a couple of Indian companies who seem to be interested in his project. However, he wants the technology to be a little cheaper before it comes to India.

The Future is in the Cloud

2009-03-27T04:11:00.001-07:00

Microsoft is changing tracks: the software giant now sees the importance of web-based services ,even though some of these edges have been around for a while already.

Windows 7 certainly got its fair share of attention when it was first shown off,but another announcement made by the microsoft at the same time might just turn out to be a lot more important.At the annual professional Developers Conference (PDC) in Los Angeles, the company’s new chief architect Ray Ozzie introduced Microsoft’s agenda for the coming years.The group wants to capture the Internet market

with new platforms and services,and Ozzie underscored the historical significance of the move by saying “It’s the transformation of our software; it’s the transformation of our strategy and our offerings across the board to fundamentally embrace services”. The vehicle which take Microsoft on that transformational journey , he revealed,is Windows Azure a new “cloud computing “ platform designed to offer users access to computing applications on any Internet-connected device from anywhere on planet.

What is cloud computing?

Users traditionally use softwares installed on their terminals , whether these are desktop PCs,laptops,cellphones or other devices.For bussines and enterprise scenarios ,individual servers or racks of them operate behind the scenes ,depending on the type of applications they need to support and the scale of the organization.When these companies have millions of customers who uses their websites and online services,they need to maintain massive data centres to ensure constant speed and uptime(which might involve multiple physical locations around the world).
The web is fast becoming the primary contact of contact for businesses,which means they can’t go offline when demand peaks.For example a shopping site that can’t deal with a spike in traffic during a holiday season will go offline ,causing massive business looses as well as customer dissatisfaction.On the flip side ,investments in processing power of this magnitude will not always be worthwhile .If it’s night time in North America,servers there are almost idle whereas those in India are under full load since it is day time here.

With cloud computing ,processing loads can be easily redistributed between idle servers.By hosting applications on a platform that consists of millions of distributed centres around the world rather than a single server ,customers don’t have to worry about uptime,latency,capacity,power supply,or even natural disasters and geopolitical events .Paying for only the server capacity you need means you can scale your infrastructure requirements fairly easily,based on peaks and valleys in user demand.Meanwhile the hosts of cloud use advanced virtualisations techniques to host multiple clients ,but not necessarily on individual machines or in single physical locations.This greatly optimizes space,power consumption and overall costs , and works out particularly well for small start-ups which don’t know how much demand their services can cope with and how much power they must purchase at the outset .Some might even need to rent bursts of power to analyze complex simulations every now and then.the cloud automatically provides them with required capacity also redistributes load evenly…………

The spread of the computer virus

2009-03-26T03:55:00.000-07:00

Viruses likeMydoom ,CodeRed and llove you have been bringing PCs to a standstill ,slowing down the internet and causing crores of rupees worth of damage for more than 20 years now

When Fred Cohen ,a student at the University of Sothern California,wrote a thesis on the possibility that computers would not be defended from malicious programs,nobody guessed that he was layingground for a $3.8 billion industry.In 1984,Cohen published a paper titled "Computer viruses : Theories and Experiments" that not every professor would allow his student to go through today. The paper described thestructure of a theoretical program which could multiply and carry out commands without the user's knowledge: the conceptualization of first virus.

everything was going fine in the mid-eighties; and if a ever disappeared it was most likely due to aprogramme error or simple carelessnes on the part of the user.But only a couple a year latter, a new type of virus start emerging
- the so-called polymorphic type of virus could change itself and encrypt the malicious payload .Many firms in the still-nascent antivirus industry couldn't deal with the next advancement , and threw in their towels .The few that remained had to clean up the fallout of virus construction kits ,which started becoming quite popular and allowed every PC novice to program malware and cause the billions of dollars of worth damages...

Viruses for everyone: infection through the web

In the pre-Internt era it wasn,t easy for virus swriters to circulate their creations their creations ,since floppy disks were the only the widespread means of transmission.The golden age for crooks dawned with the emergence of the Internet . now they can send their to all over world from their own homes-all that was needed a web connection..The internet also introduced antivirus manufactures to a new problem -until then ,experts had studied every virus individually and come up with individual tools to deal with them.Three hundred viruses per day were not too much of a burden but the number quickly rose to 30,000 per day.

As a result , the antivirus vendors had to built large computers centres and write tools that automatically analyze virus samples to determine their signatures.Today,such analysis takes a cople of seconds -only in difficult cases do the experts personally examine any data.In recent times,it is not just PCs but also cellphones that have been affected by viruses attacks .Thankfully,only a limited number of threats have surfaced so far, but that could change in the near future with the advent of synchronization services such as Microsoft Live Mesh and Apple MobileMe ,which consatntly updates data between cell phones and computers. These serve as perfect distribution method for viruses- there is no real protection against such attacks yet.Even Fred Cohen concluded in his computer can only be perfectly safe when it is completely isolated from contact with other computers .that is it can't be networked or allow any foreign storage medium to be connected .Today this is not practically possible .There is nothing we can do but be careful and trust the antivirus industry,which in turn has to continuously react to new types of threats and provide users with tools to keep us on top of the daily cat-and-mouse game we face............

When Fred Cohen ,a student at the University of Sothern California,wrote a thesis on the possibility that computers would not be defended from malicious programs,nobody guessed that he was layingground for a $3.8 billion industry.In 1984,Cohen published a paper titled "Computer viruses : Theories and Experiments" that not every professor would allow his student to go through today. The paper described thestructure of a theoretical program which could multiply and carry out commands without the user's knowledge: the conceptualization of first virus. everything was going fine in the mid-eighties; and if a ever disappeared it was most likely due to aprogramme error or simple carelessnes on the part of the user.But only a couple a year latter, a new type of virus start emerging - the so-called polymorphic type of virus could change itself and encrypt the malicious payload .Many firms in the still-nascent antivirus industry couldn't deal with the next advancement , and threw in their towels .The few that remained had to clean up the fallout of virus construction kits ,which started becoming quite popular and allowed every PC novice to program malware and cause the billions of dollars of worth damages...

Viruses for everyone: infection through the web

In the pre-Internt era it wasn,t easy for virus swriters to circulate their creations their creations ,since floppy disks were the only the widespread means of transmission.The golden age for crooks dawned with the emergence of the Internet . now they can send their to all over world from their own homes-all that was needed a web connection..The internet also introduced antivirus manufactures to a new problem -until then ,experts had studied every virus individually and come up with individual tools to deal with them.Three hundred viruses per day were not too much of a burden but the number quickly rose to 30,000 per day. As a result , the antivirus vendors had to built large computers centres and write tools that automatically analyze virus samples to determine their signatures.Today,such analysis takes a cople of seconds -only in difficult cases do the experts personally examine any data.In recent times,it is not just PCs but also cellphones that have been affected by viruses attacks .Thankfully,only a limited number of threats have surfaced so far, but that could change in the near future with the advent of synchronization services such as Microsoft Live Mesh and Apple MobileMe ,which consatntly updates data between cell phones and computers. These serve as perfect distribution method for viruses- there is no real protection against such attacks yet.Even Fred Cohen concluded in his computer can only be perfectly safe when it is completely isolated from contact with other computers .that is it can't be networked or allow any foreign storage medium to be connected .Today this is not practically possible .There is nothing we can do but be careful and trust the antivirus industry,which in turn has to continuously react to new types of threats and provide users with tools to keep us on top of the daily cat-and-mouse game we face............theory In one of his works ,John Von Neumann puts forth the theory that a computer program can replicate itself on its own.

1982

15 year old student Rich Skrenta writes a program called Elk Cloner that spread itselfs in the system through disks.It uses the boot sector to propagate itself.

1984

Fred Cohen introduces the first functioning virus in his thesis, which is written for the unix systems.

1986

Pakistan Connection Softwares retailers from the middle east spreadthe first dos virus .The progrmas renames disks but doesn't causes any great damage..

1987

1. Jerusalem This is the first virus that causes permanent damage it deletes all COM and EXE files fromthe disk on wvery friday till 13th. 2.Resisting detection The cascade virus coceals itself in the infected system's RAM 1988 Virus constructions kits a virus constructions kit appears for the popular atari st computers with which even beginners can write malware that resists detection- all without any program language. 1989-1972 1.Antivirus tools
fight viruses make their first appeareances..

2.Virus win a round Malware writers start creating polymorphic viruses which are more difficult to detect on ainfected pcs.Many antivirys manufacturers give up since they are unable to find a solution to this problem.

3. Michelangelo The first virus that captures the attention of a media .It lise dormanton infected machines till march 6,the artists birthday ,when it overwrites the boot sector.. 1995 Macro viruses. The first malware for world and other such programs ,make their appeareances .Due to frequent document exchanges ,the virus circulates more than those which attack the operating system. 2000 I love you The worm "lloveyou" spreads via mail and causes damage worth billions with in days,by deelting files from affected pcs 2002 Independentof the os New generations of viruses can also infect files on linux machines, apart from windows appliacations.

2004

1.Sasser A german student programs a virus that shuts down PCs , causing huge bussiness losses and disruptions .

2. cell phones The first virus for cellphones came . A year later later they make appeareance on Symbian devices .however they have not spread much. 2006 A research group from holland introduces a new wormthat can spread itself through rfid radio transmissions. 2009------------------> "FUTURE" Viruses everywhere communications medium such as mobile and PCs are always connected to each other throgh networks.MAlware will attack these systems and simultaneously delete or exploit available data.

This is not much about viruses but i have to end my discussions here.

how to install ubuntu on your windows laptop ...........

2009-03-09T13:33:00.000-07:00

As everyone want to have linux in his system but it is very difficult to install it.but now to install linux there are very easier ways.now , here i am discuss about the installation of ubuntu 8.1 on your windows.

first make a partition of about 10 gb on your system by vista diskmgmt,msc command type diskmgmt.msc on your run menu and there is a way to create new partition.now insert your ubuntu 8.1 into your optical drive and reboot the computer.in the bios make changes in boot options and make the optical drive first preferences in boot order.now your system boots with ubuntu live cd.now when u boot through your ubuntu cd then a graphic user interface comes or you can say desktop.in the desktop there is a icon name install now click the icon.then a windows pops-up with the welcome menu gives u an option to choose your language.choose your appropiate language and click on forward now another windows pops up and it ask for your time-zone choose your appropiate time zone click on forward button and then it asks for keyboard layout choose your appropiate keyboard english users should use usa keyboards and click forward button then it shows setting up partitioner.there are two ways to partition your disk one is guided one other one is manual one.guided one uses to install linux on the free space you created on windows. so new ones should use this method and click forward this windows ask you to fill up your profile.and caution dont fill password and login name it shows a error.and click forward .and after this is the last window before installing and click ready to install and get ready for linux. at the end a grub is loaded it shows you the menu for the both windows and linux.
