Adobe AIR – The Adobe Integrated Runtime (AIR) is an interesting development that enables web designers and developers to use the technologies used to build web sites - HTML, Javascript, Flash - to build applications that are used on the desktop.

The types of applications being built with AIR are those that integrate closely with websites. Some are used to follow and analyse information published by web sites while others are used to updates web sites and blogs.

Because they run on the the desktop and not in a web browser they can offer more features and access and save files on the local hard drive or network. AIR also has built in database for storage and synchronisation so you can work offline and then synchsronise the information to your website at a later date.

At present AIR runs on Windows and Mac OS X. A version for Linux is available to developers and a version for mobile devices is in development.  Click here for source

Content Delivery Network (CDN) – a specialist network of computers optimized to deliver web sites, pictures, videos and software downloads to people visiting a web site in the quickest, most efficient way possible. Computers in the network work together to share the load of delivering these files and to enable companies to deal with large peaks in demand. CDN providers include companies such as Akimai, Coral CDN and Limelight Networks.

When delivering a web page from a web server to a user's machine, distance is a factor. The distance from a user's machine to the actual location where the files are hosted does have an impact on download speeds. Use of a CDN can reduce download delays by detecting country the user is located in and using files from the geographically nearest web server.  Click here for source

"Google puts flu tracker to work on swine flu"

Well, lately swine flu has been threatening everyone. Today (April 29, 2009) Google said that it "saw a spike in searches for information about flu among people in Mexico last week even before news of the outbreak became widely known." Google found it by tracking information submitted through people’s searches - those who were sick were looking for the same type of information about the disease. Such results are generated by  U.S. Google Flu tool launched last fall. In the future such tool or any other similar can help predict outbreaks before they become widely spread.

"Oracle to Buy Sun"

With the acquisition of Sun Microsystems, Oracle finds reciprocal benefits.

"There are substantial long-term strategic customer advantages to Oracle owning two key Sun software assets: Java and Solaris. Java is one of the computer industry's best-known brands and most widely deployed technologies, and it is the most important software Oracle has ever acquired. Oracle Fusion Middleware, Oracle's fastest growing business, is built on top of Sun's Java language and software. Oracle can now ensure continued innovation and investment in Java technology for the benefit of customers and the Java community.

The Sun Solaris operating system is the leading platform for the Oracle database, Oracle's largest business, and has been for a long time. With the acquisition of Sun, Oracle can optimize the Oracle database for some of the unique, high-end features of Solaris. Oracle is as committed as ever to Linux and other open platforms and will continue to support and enhance our strong industry partnerships."

"Computer experts brace for "Conficker" worm"

Again the topic of stealing information through the Internet comes out. This time the thing is about malicious software called “conficker” worm. “Conficker, believed to reside on 2 milion to 12 milion computers worldwide, is deigned to turn an infected PC into slave that responds to commands sent from a remote server that controls an army of slave computers known as a botnet.”So it goes with steling identities, log sensitive corporate information, credit card numbers, online banking passwords and other. In other words, people are under threat. Even FBI is trying to solve the problem. This is a really bad situation called no more a cyber crime but “criminal attack” (according to Microsoft).

I remember once I got that mail from my bank that my personal data is under threat of being stolen. I wonder what they exactly had in mind? Maybe they were talking about “Conficker” computer virus…hmmm…I just hope it is not as serious as it seems.
