Is your computer “male” or “female”??



1. Open Notepad

2. Type the following line in notepad:

CreateObject("SAPI.SpVoice").Speak"I love you"

3. Save file as computer_gender.vbs in any location

4. Run the file by double clicking on it... If you hear a male voice, you have a boy If you hear a female voice, you have a girl (:

Note: Turn on the speaker before running the file :)

IBM To Build Next Generation Chips Using DNA

In future DNA wouldn’t just control human evolution but also computing evolution, if IBM succeeds to use DNA in development of next-generation microchips.


Scientists at IBM Research and the California Institute of Technology announced a scientific advancement that could be a major breakthrough in enabling the semiconductor industry to pack more power and speed into tiny computer chips, while making them more energy efficient and less expensive to manufacture.
Today, the semiconductor industry is faced with the challenges of developing lithographic technology for feature sizes smaller than 22 nm and exploring new classes of transistors that employ carbon nanotubes or silicon nanowires. IBM’s approach of using DNA molecules as scaffolding  – where millions of carbon nanotubes could be deposited and self-assembled into precise patterns by sticking to the DNA molecules – may provide a way to reach sub-22 nm lithography.

The utility of this approach lies in the fact that the positioned DNA nanostructures can serve as scaffolds, or miniature circuit boards, for the precise assembly of components – such as carbon nanotubes, nanowires and nanoparticles – at dimensions significantly smaller than possible with conventional semiconductor fabrication techniques. This opens up the possibility of creating functional devices that can be integrated into larger structures, as well as enabling studies of arrays of nanostructures with known coordinates.
“The cost involved in shrinking features to improve performance is a limiting factor in keeping pace with Moore’s Law and a concern across the semiconductor industry,” said Spike Narayan, manager, Science & Technology, IBM Research – Almaden. “The combination of this directed self-assembly with today’s fabrication technology eventually could lead to substantial savings in the most expensive and challenging part of the chip-making process.”
The lithographic templates were fabricated at IBM using traditional semiconductor techniques, the same used to make the chips found in today’s computers, to etch out patterns. Either electron beam or optical lithography were used to create arrays of binding sites of the proper size and shape to match those of individual origami structures. Key to the process were the discovery of the template material and deposition conditions to afford high selectivity so that origami binds only to the patterns of “sticky patches” and nowhere else.
The paper on this work, “Placement and orientation of DNA nano structures on lithographically patterned surfaces,” by scientists at IBM Research and the California Institute of Technology, will be published in the September issue of Nature Nanotechnology and is currently available at: http://www.nature.com/nnano/journal/vaop/ncurrent/abs/nnano.2009.220.html.

Nokia Unveils Its First Linux Phone N900

Nokia's First Linux Phone N900





Nokia unveiled N900, its first smart phone running on Linux software, aiming at improving its offering at the top end of the market.
The Nokia N900 runs on the Linux-based Maeme 5 software, featuring true multitasking with applications as well as Web browsing with Adobe Flash support.

Nokia’s workhorse Symbian operating system controls half of the smartphone market volume — more than its rivals Apple, Research in Motion and Google put together. Nokia said Linux would work well in parallel with Symbian in its high-end product range.
“As Nokia announces the software platform that will drive its future services aspirations it created a dedicated solutions unit — the challenge will be to ensure that all these elements work in harmony in the face of fierce competition from Apple and Google,” said Ben Wood, head of research at CCS Insight.
The new N900 model, with cellular connection, touch screen and slide-out keyboard, will retail for around $712, excluding subsidies and taxes.
Nokia also unveiled a new Solutions business unit, which aims to better tie together its phone operations and new mobile Internet services offering.

The University of Calgary, Faculty of Medicine scientists who proved it is possible to cultivate a network of brain cells that reconnect on a silicon chip—or the brain on a microchip—have developed new technology that monitors brain cell activity at a resolution never achieved before.
Developed with the National Research Council Canada (NRC), the new silicon chips are also simpler to use, which will help future understanding of how brain cells work under normal conditions and permit drug discoveries for a variety of neurodegenerative diseases, such as Alzheimer’s and Parkinson’s.

The new technology from the lab of Naweed Syed, in collaboration with the NRC, is published online this month in the journal, Biomedical Devices.
“This technical breakthrough means we can track subtle changes in brain activity at the level of ion channels and synaptic potentials, which are also the most suitable target sites for drug development in neurodegenerative diseases and neuropsychological disorders,” says Syed, professor and head of the Department of Cell Biology and Anatomy, member of the Hotchkiss Brain Institute and advisor to the Vice President Research on Biomedical Engineering Initiative of the U of C.
The new neurochips are also automated, meaning that anyone can learn to place individual brain cells on them. Previously it took years of training to learn how to record ion channel activity from brain cells, and it was only possible to monitor one or two cells simultaneously. Now, larger networks of cells can be placed on a chip and observed in minute detail, allowing the analysis of several brain cells networking and performing automatic, large-scale drug screening for various brain dysfunctions.
This new technology has the potential to help scientists in a variety of fields and on a variety of research projects. Gerald Zamponi, professor and head of the Department of Physiology and Pharmacology, and member of the Hotchkiss Brain Institute, says, “This technology can likely be scaled up such that it will become a novel tool for medium throughput drug screening, in addition to its usefulness for basic biomedical research”.
