We’ve seen DVDs replacing CDs,But what next??The next on arena are HD-DVD and Blue-Ray Disc.Both use a blue-laser for read-write instead of the usual red laser in curreb\nt generation DVDs.Blue rays have the shortest wave lenght among the visible spectrem.So it can pack more data within the same space.Both HD-DVD and Blure-Ray DVD use Blue laser ,but they use the technology in two ways.Lets go deep into two of’em
Blue-ray discs are more efficient with using the blue laser and pack at least 25GB per layer,whichcan be increased in multiples of 25 as you add more layers and use both sides of the media.The developers are saying that they could introduce 50GB this year and then by 2007 it will reach 200GB.To achieve this they use a completely new technology and hence it costs lot for mass production….lot means…sony released a 23GB Blue ray drive with SCSI and USB interface and the cost is well above 1.25Lakhs Rs.
HD-DVD on the other hand starts with 15 GB per layer and the capacities wud therefore increase in multiples of 15.Blue_ray is definitly a superio technology.But technology alone wont save a product.Production and marketing costs are also important.But HD-DVD maintains some backward compatability with DVD,so the same production facilities can be used to manufacture its products,meaning lesser production cost ,faster time to market and low cost to products.And there is a rumour that Microsoft will ship its upcoming OS Longhorn on HD-DVDs.But Blue-ray is more activewith more than 70 MNCs suppoting it including giant Sony,Hp,JVC,TDK …So at moment it seems like that inspite of the price ,future is with Blue-Ray.But it will not be a surprise if both technologies co-exists like the DVD+R/RW and DVD-R/RW formats.

I think every one knows about P2P file sharing…You can get any(legal & illegal) files frm a P2P (peer to peer) network. Even thogh it claims that P2P networks works efficiently by utilising full bandwidth available it will take ages to get a movie or a game.Now here is Internet2.Its still in developing stage and is under test on universties across US where it is mainly used for research purpuses.Now Students are using it for illegal file transfer.They transfer Movies and song collections with in a second(6GB+/Sec).College campuses are the front lines of the recording industry’s anti-peer-to-peer (P2P) crusade, and many schools have placed technical restrictions on student downloading. However, students often find a workaround. And Internet2, known as i2hub, may prove to be that work around.
Unlike the Internet itself, i2hub enables student file-swappers to transmit large files — like song collections or movies — almost as fast as you can say “Avril Lavigne.” Earlier this month, a team of international researchers broke an i2hub record by transferring data over 7,000 miles at a speed of 6.25 GB per second –- approximately 10,000 times faster than an average broadband connection.
Using the i2hub for the unauthorized transmission of copyrighted material is forbidden, Internet2 universities have been at the forefront of working with the recording industry and motion picture industry to make prevent those things from happening.
Many universities, under pressure from recording and film companies, now include bandwidth-limiting software on their campus networks. This can slow file swapping to a crawl — or stop it altogether.
Some schools, like the University of California at Los Angles (UCLA), are experimenting with software that automatically restricts student Internet access in response to a copyright-holder complaint. Other colleges are considering applications that filter network traffic on an individual basis in an attempt to block illegal file swapping.

The high-speed network is the product of a consortium of about 200 universities, working in concert with technology companies and government, intended to develop and use advanced network technologies. Using i2hub,Scientists and researchers are able to do things like TV-quality video conferencing…and access supercomputers for grid computing in ways the commercial Internet can’t support..
Te network infrastructure of many universities would allow them to apply restrictions at a campus level to Internet2 as well as the commercial Internet.Because all of a campus’s networks are tied together, the tactics universities use to fight unauthorized swapping would be “equally effective” on both the Internet and Internet2, he said.
The bottom line is clear: University Internet access is not the ticket to free-for-all file swapping it once was.

An Israeli scientist.Elad Barkan and his team found a flaw in the GSM(Global System for Mobile communications) code that allow you to break into mobile phone calls and even take over callers identity.According to Barkan,The GSM code gives high prority to call qualities and noise interference correction after which it encrypts the call.This enabled the hackers to break into the call.
The GSM association said that they know about this vulnerability,and had even released a patch to fix the encryption algorithm.However the hackers claimed that they managed to surpase the new encryptin system. So its not safe to carry out confidential conversation over GSM networks as your rivals can easily tap it.

When you rightclick ‘My Computer’ and choose properties, or on the Control Panel click System, there’s your systems’ properties. The first tab you might consider your machines’ id. Underneath the screen might be a picture already, provided by the manufacturer of your machine.So what about hacking it?? Like this……..

[click the image to view in full size]

Interested in trying it in ur system???…okay…but be prepared…

1.Check for a file Oemlogo.bmp on system32 folder
2.If it is there then just edit tht pic,else create a bmb image below 160*160 size and save it in system32 folder with the name Oemlogo.bmp.
3.If the file was there already then there will ben a file named Oeminfo.ini.If not there, create a .txt file there and rename it .The syntax of the file would be

[General]
Manufacturer=Your fake company like srijith v
Model=Whatever you call your machine SupportURL=http://www.virtualplastic.net/
LocalFile=Path to local html file
[ICW]
Product=Tell us, please!
[OEMSpecific]
SubModel=More branding to edit
SerialNo=xxxxxxxxsrijith v yyyyy
OEM1=Srijith V
OEM2=rules!!
[Support Information]
Line1=If item is there, and
Line2=at least one line set,
Line3=”Support information button” appears
Line4=and info in the lines appears.
Line5=
Line6=Use empty lines for a spacebreak,
Line7=as many lines as you’d like,
Line8= …etc

The first two lines, Manufacturer and Model, are displayed on this tab. Actually, you can leave the model line empty; it’s the manufacturer line that is required to display oemlogo.bmp. Anything else is optional, and when an oeminfo.ini is found initially, mostly the [ICW] and [OEMSpecific] sections aren’t even there, neither are the SupportURL/LocalFile lines.

Now i know u may hav some doubts Well…I know ..You may may have doubts about how to change ……….ok post a comment here…i’ll check it..no time now!!
