Overview of the MPEG-4 Standard

MPEG-4 is an ISO/IEC standard developed by MPEG (Moving Picture Experts Group), the committee that also developed the Emmy Award winning standards known as MPEG-1 and MPEG-2. These standards made interactive video on CD-ROM, DVD and Digital Television possible. MPEG-4 is the result of another international effort involving hundreds of researchers and engineers from all over the world. MPEG-4, with formal as its ISO/IEC designation ‘ISO/IEC 14496’, was finalized in October 1998 and became an International Standard in the first months of 1999. The fully backward compatible extensions under the title of MPEG-4 Version 2 were frozen at the end of 1999, to acquire the formal International Standard Status early in 2000. Several extensions were added since and work on some specific work-items work is still in progress.

HowToForge: Back Up/Restore Hard Drives And Partitions With Ghost4Linux

This tutorial shows how you can back up and restore hard drives and partitions with Ghost4Linux. Ghost4Linux is a Linux Live-CD that you insert into your computer; it contains hard disk and partition imaging and cloning tools similar to Norton Ghost. The created images are compressed and transferred to an FTP server instead of cloning locally.

A Small Introduction in Wireless Lan Penetration

Wireless LANs (WLAN) are becoming increasingly popular. They’re extremely convenient for lap top users, and for home networks : no need for cables all over the place, just sniff the air waves and connect. Obviously, this poses kind of a risk : anyone with a WLAN enabled computer can look around, see what WLAN’s are there to be found, and come in to have a look. While IT professionals (hopefully) hopefully understand these risks, the average home user or DIY adept might just unpack his new toys, set them up, and leave the wireless network unprotected. Happens all the time. After all, buyers expect things to work “out of the box” – so vendors sell their stuff so that it will.

Used to be so that WLAN’s were secured through WEP – The Wireless Encryption Protocol. Without access to the right key, it would be impossible to decrypt the data flying around on the air waves. Unfortunately, WEP encryption proved quite weak, and can easily be broken. What follows is a 5 step intrusion guideline : it shows how easy it can be to get access to a wireless network. It is based on a commercial from a company that sells security …

Proposal for Porn Domain Revived

A net domain for pornography was originally considered in 2001. A proposal was made in June 2005, a final approval was expected in December 2005 but was delayed to May 2006 and was quickly rejected. Over the years, conservative groups, politicians and pornographers have actively criticized the .xxx domain idea. Operators do not like the idea of easily masse blocking of porn sites.

ICM registry, the backer of .xxx, has made sure that site.xxx will not hit a user with spam or spyware and will use a system to label their content. ICM has also taken steps to ensure child pornography or anything of the like is not available or promoted. ICM promises to actively police all .xxx sites. Internet Corporation for Assigned Names and Numbers (Icann) has invited the public to comment on the revised .xxx agreement with the final cutoff date being February 5, 2007. If final approval is won it is not yet clear when the domain could start operating.

Indian-born scientist developing coated DVD’s for 50 terabytes (50000GB)

Sydney, Jul 8 (ANI): An Indian born scientist in the US is working on developing DVD’s which can be coated with a light -sensitive protein and can store up to 50 terabytes (about 50,000 gigabytes) of data.

Professor V Renugopalakrishnan of the Harvard Medical School in Boston has claimed to have developed a layer of protein made from tiny genetically altered microbe proteins which could store enough data to make computer hard disks almost obsolete.

“What this will do eventually is eliminate the need for hard drive memory completely,” ABC quoted Prof. Renugopalakrishnan, a BSc in Chemistry from Madras University and PhD in biophysics from Columbia/State University of New York, Buffalo, New York as saying.

The light-activated protein is found in the membrane of a salt marsh microbe Halobacterium salinarum and is also known as bacteriorhodopsin (bR). It captures and stores sunlight to convert it to chemical energy. When light shines on bR, it is converted to a series of intermediate molecules each with a unique shape and colour before returning to its ‘ground state’.

Since the intermediates generally only last for hours or days, Prof Renugopalakrishnan and his colleagues modified the DNA that produces bR protein to produce an intermediate that lasts for more than several years. They also engineered the bR protein to make its intermediates more stable at the high temperatures generated by storing terabytes of data.

This, they said, ultimately paved the way for a binary system to store data.
