2,000 Movies All On One DVD!!!


How do you like to store 2,000 movies on ONE DVD.... a piracy business owner's nightmare, so too for movie companies and producers... how easy will it be to duplicate and transfer if you could store in the one DVD. You could be a traveling piracy dealer with just a notebook and that one DVD.

Australian scientists have unveiled new DVD technology that stores data in five dimensions, making it possible to pack more than 2000 movies onto a single disc. A team of researchers at the Swinburne University of Technology in Melbourne, have used nanotechnology to boost the storage potential nearly 10,000-fold compared to standard DVDs, according to a study published in the peer-reviewed journal Nature.

"We were able to show how nanostructured material can be incorporated onto a disc in order to increase data capacity, without increasing the physical size of the disc," said Min Gu, who led the team.

Discs currently have three spatial dimensions. By using gold nanorods Gu and colleagues were able to add two additional dimensions, one based on the colour spectrum, and the other on polarisation. Because nanoparticles react to light depending on their shape, it was possible to record information in a range of different colour's wavelengths at the same physical location on the disc. Current DVDs record in a single colour wavelength using a laser.

The fifth dimension was made possible by polarisation. When light waves were projected onto the disc, the direction of the electric field within the waves aligned with the gold nanorods.

"The polarisation can be rotated 360 degrees," explained co-author James Chon.

"We were, for example, able to record at zero degree polarisation. Then on top of that, were able to record another layer of information at 90 degrees polarisation, without them interfering with each other," he said in a statement.

The researchers are still working out the speed at which the discs can be written on, and say that commercial production is at least five years off. They have signed an agreement with Korea-based Samsung, one of the world's largest electronics manufacturers. Last month, US technology giant General Electric said its researchers had developed a holographic disc which can store the equivalent of 100 standard DVDs. - AFP/SMH

My Master, A National Treasure

REPOST:  Its been more than two years since I posted on my sifu. This is probably the most significant posting I had done thus far that does not involve business or politics. My circle of close friends and business colleagues have benefited significantly from his treatment.


My Master, Dr. Law Chin Han (from my iPhone)

Where shall I start? OK, just based on real life experiences of those who are close to me. The entire Tong family (Bukit Kiara Properties) absolutely swear that he is the master of masters when it comes to acupuncture (and dentistry as well). To me, you can probably find many great dentists, but to find a real Master in acupuncture, thats a whole different ballgame.


I am not big aficionado of Chinese medicine or acupuncture initially. I guess you have to go through the whole shebang to appreciate the real life changing effects from a master.


My business partner and very close friend went to him after 15 years of persistent gout problem, he will get his heavy attacks at least…

PUC - An Assessment

PUC has tried to reinvent itself following the untimely passing of its founder last year. His younger brother, who was highly successful in his own right, was running Pictureworks in a number of countries in Asia.

The Shares Price Rise & Possible Catalysts

Share price has broken its all time high comfortably. The rise has been steady and not at all volatile, accompanied by steady volume, which would indicate longer term investors and some funds already accumulating nd not selling back to the market.


Potential Catalyst #1

The just launched Presto app. Tried it and went to the briefing. Its a game changer for PUC for sure. They have already indicated that the e-wallet will be launched only in 1Q2018. Now what is Presto, why Presto. Its very much like Lazada or eBay or Alibaba. Lazada is a platform for retailers to sell, full stop. eBay is more for the personal one man operations. Alibaba is more for wholesalers and distributors.

Presto links retailers/f&b/services originators with en…

How Long Will The Bull Lasts For Malaysia

Are we in a bull run? Of course we are. Not to labour the point but I highlighted the start of the bull run back in January this year... and got a lot of naysayers but never mind:






























p/s: needless to say, this is Jing Tian ... beautiful face and a certain kind of freshness in her looks and acting career thus far



http://malaysiafinance.blogspot.my/2016/12/bank-negara-may-have-switched-on-bull.html


I would like to extend my prediction that the bull run for Bursa stocks should continue to run well till the end of the year. What we are seeing for the past 3 weeks was a general lull where volume suddenly shrunk but the general trend is still intact. My reasons for saying so:

a) the overall equity markets globally will be supported by a benign recovery complemented by a timid approach to raising rates by most central banks

b) thanks to a drastic bear run for most commodities, and to a lesser extent some oil & gas players, the undertone for "cost of materials" have been weak and has pr…
