As a gauge of storage demand, IDC says the total amount of disk storage shipped last year grew 40.5 percent from 2007. But with the storage requirements of average enterprises rapidly growing, keeping it all forever can create long-term management challenges and lead to headaches when something needs to be found. Analysts, attorneys, and vendors say enterprises are better off getting rid of some data -- but doing it judiciously. For IT departments, that means planning, carefully executing, and not going it alone. Companies that save everything are often those that aren't sure what needs to be saved or deleted. On top of the price of disks, tapes, networks and management, piling up too much data can come back to haunt a company in case of a lawsuit. It may cost $1 million to find and compile the data requested in "e-discovery," the process of collecting electronic data as evidence.

"Archiving should be used only to selectively retain information for specific periods of time. Separated from backup and done with specialized tools, the process runs more smoothly and prevents saving too much or too little information"...

"Although disks will get less expensive over time, in-house staff to manage them won't"...

AIIM - Association for Information and Image Management - is concerned about how we manage data and information. It is simply too much data and it takes too much time to find information.

Is DVD a dying medium? Have you burnt any DVDs or CDs recently? The Internet shop Komplett.no is pointing out that the sales of the abovementioned storage media have gone down. Other media like USB sticks and external hard disks are getting cheeper and hence more popular among customers. Read the whole article by clicking the link below (in Norwegian only).

Nature journal reports that it is possible to make 1,6 TB of information fit on a DVD-sized disk thanks to the new method called "five-dimensional"- 5-D optical recording. Researchers at Swinburne University of Technology in Australia added three "dimensions" to the two spacial dimesions that DVDs and CDs already have: spectral (colour), polarization and spacial - recording information in 10 layers of the nano-rod films. As a result, the scientists say they have achieved unprecedented data density. Unlike the holographic recording methods 5-D recording is bit-by-bit which allows to read each piece of information sequentially.

The ordinaty digital deletion means overwriting the overall directory - the pointers - leading to the actual information objects: the documents are therefore still there and can be reconstructed. However, total erasion is desirable in many cases, e.g. when demanded by law. To meet this need Data Domain (www.datadomain.com) has launched System Sanitation Process in its Retention Lock product. The latter allows total information destruction in a safe manner.

Wolfram|Alpha is launched! Apparently a usual search engine but not completely. It is a computational knowledge engine, which carries out search  against all accumulated knowledge residing in different sources. The inventor is Stephen Wolfram himself, who is also the man behind Mathematica.

Pictures from the mid-1960s Lunar Orbiter program lay forgotten for decades. NASA was so preoccupied with getting an astronaut to the moon that little attention was paid to the mountains of scientific data that flowed back to Earth from its early space missions. These data were stored on miles of fragile tapes, packed up and sent to a government warehouse with crates of other stuff. And it would have been destroyed without Nancy Evans' interference. The archivist knew her mission: to preserve the history of human space exploration and see the pictures restored.

A new standard for secure online preservation of images and pictures has been worked out by the IKT Norge (ICT Norway)and Forbrukerrådet (the Norwegian Consumer Council). The companies responsible for photographs storage of the public are now obliged to follow these norms. The objective of the standard is to make sure that the photographs and other pictures of people are stored in a secure way and that the situations when those are accidentally deleted or suddenly disappear become non-existent.

Ting Xu of Lawrence Berkeley National Laboratory’s Materials Sciences Division (MSD) and Tom Russell of the University of Massachusetts Amherst came up with new extremely effective storage technology. In today's computers hard drives the magnetic domains that encode bits of information measure a couple of dozen nanometers (billionth of a meter) across. The researchers found a way of ordering large nanometer-scaled arrays: each array of bits is three nanometers across, and there are ten trillion of them in a square inch, densely packed and arranged in perfect order.

SafetySafe has introduced a PC safe with an integrated USB cable for storage of personal (or business) data. The safe contains a small space inside - only big enough to room an external 2,5" harddisk. There is also space for CD and DVD preservation inside the safe (the article is in Norwegian).

Portsmouth University researchers in England are developing the universal emulator which, presumably, will be capable of recognizing and running files all the way back to the 70s. The research work is a part of the larger EU-financed KEEP - Keeping Emulation Environments Portable - project. The super-emulator will read and run text files, multimedia, web pages, databases and compuet games - all independently of the original platform (the article is in Norwegian).

Being able to store your data securely with unlimited storage space online has been a hot topic for quite some years now. LiveDrive has launched its beta version of such online storage serice, which is, in addition to being free, has also Windows Explorer interface. The service allows to work offline too by backing up the data locally. At present it is unknown when alfa version is due. This will truly be a payment service (the article is in Norwegian).

An inspired engineer uncovers the purpose of flat, grooved disks known today as vinyl records. By reconstructing the shape of some grooves from scans of the surface of a recording, he wrote software to play Vivaldi's four seasons. How did he do that and what practical applications may this experiment have? Reed more here: http://www.cs.huji.ac.il/%7Espringer/.

Bringing knowledge and enlightenment to Africa's street kids and other vulnerable children.
Lubuto libraries are special places where Africa's street kids and other marginalized children can read for themselves, look at books or have books read to them. In Lubuto libraries, children come in contact with and explore the world and their human heritage. Giving vulnerable children the opportunity to learn to read and to learn, even if they are excluded from formal schooling, will help them to go in positive directions with their lives, knowing that society is providing a place for them and cares about their welfare.
