Intel has recently showcased the new ‘Knights Ferry’ processor at a supercomputing conference in Seattle. The new chip was demonstrated running in a test machine and is capable of crossing the 1 teraflop mark, or a trillion floating point operations barrier -; something previously restricted to tens of cabinets filled with processors.

To put that into perspective, Intel unveiled the first supercomputer to cross the 1 teraflop mark in 1997. That system was comprised of 9,298 Pentium II processors that filled 72 full-sized cabinets. In comparison, the new 22nm processor, called ‘Knights Ferry’, is about the size of a matchbook and can achieve the same level of performance.

Don’t expect to see these new chips anywhere anytime soon however.  Intel and its partners hope to deliver said systems by 2018.

According to this post from TechSpot, researchers have discovered that hackers have now managed to port an old Linux trojan to work on Apple’s Mac OS X platform.

“Once it is running on the host machine, it connects to an IRC channel and awaits further commands from the hackers. They can then use the combined connections of the all the computers in the botnet to flood servers with requests, bringing them down in DDoS attacks. Hackers are able to download files to the infected computer for it to update itself or install additional malware, and gives complete control of the host machine to execute any command they choose.”

Mac users seem to think that their machines are immune to any form of infection. It’s good to know that the platform really isn’t as secure as many people think. Could this be the start of a new demand of anti - virus programs for Max OS X?

Here is a small game of Yahtzee I have been recently working on in Java. At the moment it takes the form of a standalone swing application, although I may port it to a Java applet for in browsers games. Full source code can be found on the GitHub repository

Microsoft has now released the developers preview for Windows 8, which includes -

• A 64-bit Windows Developer Preview
• Windows SDK for Metro style apps
• Microsoft Visual Studio 11 Express for Windows Developer Preview
• 28 Metro style applications including the BUILD Conference app

It’s available here.

Although I haven’t personally installed the release, here are a couple of screenshots from a user running it in a Virtual Machine.

This shows the new ‘Metro’ UI in Windows 8. It consists of a series of tiles and widgets that link to the most common applications. I can’t really see anyone using this on a desktop computer, but I suppose it’s meant to be for mobile devices with touchscreens, which will benefit hugely from the large icons.

Here is the new desktop and start menu in the developer release. Although most of the desktop is similar to that of Windows 7, huge changes can be seen in the new start menu which has been completely revamped to fit in with the new Metro style.

One of the main changes in the new release is the new Ribbon in Windows Explorer. For more basic skilled users this could be a real time saver, as it stops people from trawling through the edit menu in order to find ‘Copy’. However on the other hand, on smaller resolutions the Ribbon can take up a lot of real estate, and won’t leave much room for the actual files to be displayed. I can see most advanced users instantly hiding the Ribbon, as most of it’s features can be accomplished with simple keyboard shortcuts.

The task manager has also been given a much needed face lift. It’s now much more graphic, and offers the user more information than in previous versions. This will also apparently be a window that many users will see, as Microsoft have recently said that most people use the task manager on a day to day basis to ‘kill’ programs. This doesn’t really say much for the developers.

Finally there is the new Metro Control Panel and a possible Metro equivalent to ‘All Programs’. I hope that Microsoft still include the old versions however, as I can see trying to navigate the control panel on a desktop computer taking twice as long as it should do.

Of course this is a very early build of Windows 8, but shows a taster of what’s to come. I find it surprising that Microsoft have made such large changes from Windows 7. Obviously Microsoft are trying to integrate the new release with Windows Phone devices, and Metro will look and feel great on a touchscreen device, but I don’t really think that it offers any use whatsoever to the majority of users sitting at their desks.  Plus considering that Microsoft’s clients are mostly corporate, I can’t see the new changes being that popular with them. It will probably decrease productivity and will confuse many users, especially considering that many businesses have only just made the leap from Windows XP to Windows 7, and from Office 2003 to 2010. The leap has just been made at my college, but not without major problems. Many have had problems using Libraries, and the whole network has been down for hours at a time. Of course the problems will be fixed soon, but it doesn’t bode well for Windows 8 considering that it took the best part 8 years to upgrade to Windows 7.

Expect to see a lot more about the new release in the near future.

A few days ago Oracle announced the availability of their new Java 7 SDK. Some of of the major changes include -;

• New I/O APIs (Asynchronous I/O)
• Strings in switch statements
• Unicode 6.0
• Elliptic-curve cryptography
• Translucent and shaped windows
• Heavyweight/lightweight component mixing
• Swing Nimbus look-and-feel
• Swing JLayer component
• The integral types (byte, short, int and long) can also be expressed using the binary number system. To specify a binary literal, add the prefix 0b or 0B to the number.
• Any number of underscore characters (_) can appear anywhere between digits in a numerical literal. This feature enables you, for example, to separate groups of digits in numeric literals, which can improve the readability of your code.
• You can replace the type arguments required to invoke the constructor of a generic class with an empty set of type parameters (<>) as long as the compiler can infer the type arguments from the context. This pair of angle brackets is informally called the diamond.
• A single catch block can handle more than one type of exception. This enables you to specify more specific exception types in the throws clause of a method declaration and reduces code repetition.
• The try with-resources statement is a try statement that declares one or more resources. A resource is an object that must be closed after the program is finished with it. The try with-resources statement ensures that each resource is closed at the end of the statement.
• Java API for XML Processing (JAXP) 1.4.5.
