The most dense computer memory circuit ever - 100 gigabits per square centimeter - a new record

"The most dense computer memory circuit ever
fabricated, capable of storing around 2,000 words in a unit the size of a white
blood cell, was unveiled by scientists in California. The team of experts at the
California Institute of Technology (Caltech) and the University of California,
Los Angeles (UCLA) who developed the 160-kilobit memory cell say it has a bit
density of 100 gigabits per square centimeter, a new record. The cell is capable
of storing a file the size of the United States' Declaration of Independence
with room left over."

2.5 Terabyte Hard Drives by 2009, Says Seagate

Hard drive titan Seagate says that increasing hard disk densities could mean 4,000 hours of video on your PC, or TiVo, by 2009.

Hard drive technologies have come a hell of a long way since the 1-ton, 5 megabyte RAMAC was released in 1956. Hell, it was only a decade ago that Seagate’s 20 gigabyte drives marked an industry standard. And as Seagate and other hard-drive developers continue to push the envelope on digital media storage, the once-fabled 1 terabyte milestone may soon look like small potatoes.

Seagate announced in a press release yesterday that it anticipates maximum storage sizes of 275GB for 1″ micro drives, 500GB 2.5″ notebook drives, and 2.5TB, or 2500 gigabytes for 3.5″ desktop drives by 2009.

The claims were supported by a magnetic storage demonstration in which Seagate achieved a world record of 421 Gbits per square inch (421 Gbit/in2). Such capacities have become possible as new technologies such as Perpendicular Recording have emerged, promising higher disk dens…

RFID-Embedded Discs Could Put an End to Piracy

Disc manufacturer Ritek is developing an RFID chip to embed in disc-based media, a move that could put a big dent in software piracy.

U-Tech, a subsidiary of Ritek, is currently in development of an RFID chip that could prevent illegal copying of DVDs, CDs, Blu-ray discs and HD DVDs. U-Tech has chosen a company named IPICO to manufacture the discs, and both U-Tech and IPICO have announced plans to begin production on the new RFID-discs at one of Ritek’s factories in Taiwan.

In order for the technology to be fully functional, drive manufacturers will have to include RFID-reading technology in future products. Drives would check the RFID chip to detect whether a disc contains a copied version of copyrighted media, and whether movies are being played in the correct geographical location. Ritek’s chief executive officer Gordon Yeh had this to say about the RFID technology:

This technology holds the potential to protect the intellectual property of music compan…

Wireless USB to Clean Cable Clutter

Despite a brash of delays that have plagued the progress of wireless USB, the 480 megabits per second technology should find its way into the mainstream by the end of the year.

Certified Wireless USB, as it’s being officially called, is being developed by the WiMedia Alliance, who has been selected by the USB Implementers Forum, the 1394 Trade Association and the Bluetooth Special Interest Group (SIG) for its "Ultrawideband" (UWB) technology. Ultrawideband was chosen as the next-gen standard due to its speed and versatility. Operating at speeds around 480 megabits per second, UWB connections are faster than current USB 2.0 technologies, and with a range of up to 10 meters. Transfer rates will diminish as the wireless UWB adapters near their 10 meter limit, but the ability to operate an second external hard drive that’s 30 feet away should make up for it. Said Roger Kay, an analyst with Endpoint Technologies Associates:

This stuff is plumbing. It’s important that it be there, …

Geek to Live: Secure VNC with Hamachi

Need to look up a phone number on your home computer from the office? Or control the headless media server you set up at your buddy's place across town? Or help Mom figure out how to use Flickr? You already know that Virtual Network Computing (VNC) remote controls computers over the internet. But VNC is not a secure protocol - and it won't work if the remote machine is behind a firewall you don't control.

However, pairing up VNC with Hamachi, a Virtual Private Network application, you can remote control any computer securely over your private network across any combination of operating systems. Today we'll cover how to drive a computer over the internet with the free, secure and cross-platform VNC and Hamachi, the chocolate and peanut butter of remote computing.

The last time I wrote about VNC, several of you asked, "But why not easier-to-set-up solutions like" Well, mostly because VNC software is cross-platform and free (as in speech - no upsell).…

Smarter Printing With Word Macros

What's a Macro?

Let's say you have a paragraph highlighted in Word and that's all you want to print. You'd go to the toolbar, click File, Print, choose Selection in Page Range, and hit OK.

Word (and Excel) can watch and record the keystrokes you used to print the paragraph. You can play back those recorded keystrokes by assigning them to a keyboard combination, maybe, Control-9, or a button on Word's toolbar.

The actual step-by-step macro creation process is a snap, but it's too long to describe here. Besides, it's described in rich detail in Office XP Tips: Macros 101. (The tip works in Office 2003 and older; I haven't tried it in Office 2007.)

Stick the Macro on the Toolbar
As you create the macros, name them something smart, like "A_PrintPage" and "A_PrintSelect." Trust me, with dozens of existing macros clogging the list, this will make your two lots easier to find later.

Once you've created the macros, assign them to their own…

NanoTechnology, Storage Bits For Future Computers

For those who think Chemistry isn't that intresting as technology (at least i though so!)

In the family of Prussian blue, there is a compound that can act as a switch: it is not magnetic at the outset, but it can become magnetized by the effect of light and return to its initial state by heating. Researchers of the Institute of Molecular Chemistry and Materials of Orsay (CNRS/University of Paris XI) and the Laboratory of Inorganic Chemistry and Molecular Materials (CNRS/University of Paris VI) showed that this change of state is due to the collective modification of the position of the atoms, induced by light. Such compounds, which can memorize binary information, could be used as storage bits for future computers. This work was presented in the journal AngewandteChemie International Edition (after the online publication of January 9, 2007).

In the field of computers, society's demand for capacity to store information is increasing exponentially and has led to the development of…
