China has ratcheted up surveillance and security in every phase of the Beijing Olympics - even the tickets.

In a move unprecedented for the Olympics, tickets for the opening and closing ceremonies are embedded with a microchip containing the bearer’s photograph, passport details, addresses, e-mail and telephone numbers.

The intent is to keep potential troublemakers from the 91,000-seat National Stadium as billions watch on TV screens around the world. Along with terrorists, Chinese officials fear protesters might wreck the glitzy ceremonies, unfurling Tibet flags, anti-China banners or even T-shirts adorned with strident messages.

Aside from concerns about privacy and identity theft, the high-tech tickets also threaten chaos at the turnstiles.

Tickets for the Aug. 8 opening ceremony are the most expensive of the Games - with a top price of US$720 - and many are in the hands of dignitaries and friends. Delays could create terrible publicity on opening night.

Malware hunters have spotted a previously unknown — and unpatched — Adobe Flash vulnerability being exploited in the wild.

The zero-day flaw has been added to the Chinese version of the MPack exploit kit and there are signs that the exploits are being injected into third-party sites to redirect targets to malware-laden servers.

Adobe’s product security incident response team is saying that all versions of Flash Player 9.0.124.0 are not vulnerable to these exploits.

So, hosting and managing a ton of Ajax calls, even when working with mootools, dojo or scriptaculous, can be quite cumbersome, especially as they get updated, along with your code. In addition, several sites now use these libraries, and the end-user has to download the library each time.

Google now will provide hosted versions of these libraries, so users can simply reference Google’s hosted version. From the article, ‘The thing is, what if multiple sites are using Prototype 1.6? Because browsers cache files according to their URL, there is no way for your browser to realize that it is downloading the same file multiple times. And thus, if you visit 30 sites that use Prototype, then your browser will download prototype.js 30 times.

Today, Google announced a partial solution to this problem that seems obvious in retrospect: Google is now offering the “Google Ajax Libraries API,” which allows sites to download five well-known Ajax libraries (Dojo, Prototype, Scriptaculous, Mootools, and jQuery) from Google. This will only work if many sites decide to use Google’s copies of the JavaScript libraries; if only one site does so, then there will be no real speed improvement. There is, of course, something of a privacy violation here, in that Google will now be able to keep track of which users are entering various non-Google Web pages.

Call/Recall has announced it is developing a 1TB optical drive and disk, backwards compatible with Blu-ray, in partnership with with the Nichia Corporation of Japan.

Call/Recall began synthesizing 1TB materials for Nichia’s blue-violet laser diodes in December 2007, with first initial testing successfully completed in March 2008.

InPhase has just this year announced its revolutionary 300GB holographic disk and here is another optical format with more than three times the capacity. How realistic is this?

Call/Recall and Nichia will jointly develop the ultra high-capacity optical disc recording and playback system. It is designed around Nichia’s commercially available violet and blue laser diodes and Call/Recall’s one terabyte media.

One secret sauce is the use of a Rhodamine-type dye in a recording layer. It is excited by laser light and reacts to give off light when excited by another laser at a different wavelength. Such light emission or its absence can be used to indicate binary ones and zeroes.

The dye spots are tiny and can exist in 200-250 layers thus providing the 1TB capacity. The use of a single lens to read multiple layers is enabled by having a fluid-filled lens and increasing/reducing the fluid content and thus the lens’ profile and its focal length.

The I/O rate is said to be around 100MB/sec, five times faster than InPhase’s holographic drives.

The process is not reversible and produces write-once-read-many (WORM) media. Reversibility is being worked on and there is a generalised roadmap out to 5TB, still on CD-sized 120mm platters.

Google Inc. showed off its nearly completed mobile software system to about 3,000 computer programmers Wednesday, hoping to cultivate more services and advertising for people on the go.

Although brief, the demonstration at the Internet search leader’s annual developer conference in San Francisco represented the most extensive public look so far at “Android” - an open-source platform being designed for “smart” phones and other mobile devices that surf the Web. Android was first announced nearly seven months ago.

The bells and whistles unveiled Wednesday included: a way to unlock phones by drawing a specific shape on the touchscreen instead of entering a password; bookmarks for favorite Web sites on the device’s home page; a “compass” tool that automatically roams with the phone while a user looks at photographic images of a city map; a magnifying tool to zoom in on Web content; and a mobile version of the video game “Pac Man.”

The demonstration relied on touchscreen technology similar to Apple Inc.’s iPhone, but Android can also be tailored to work with a tracking ball, said Andy Rubin, who is overseeing the project.

While acknowledging the work on Android is nearly done, Rubin deflected a question about how much longer consumers will have to wait for a phone powered by the new software. Sticking to the timetable Google has used throughout the project, Rubin said Android will hit the market some time during the final six months of this year.
