MAC OS X
Mac OS X's core is a POSIX compliant operating system (OS) built on top of the XNU kernel, with standard Unix facilities available from the command line interface. Apple released this set of software as a free and open source operating system named Darwin. On top of Darwin, Apple layered a number of components, including the Aqua interface and the Finder, to complete the GUI-based operating system which is Mac OS X.Mac OS X introduced a number of new capabilities to provide a more stable and reliable platform than its predecessor, Mac OS 9. Many aspects of Mac OS X's architecture are derived from Openstep, which was designed to be portable—to ease the transition from one platform to another. Mac OS X includes its own software development tools, most prominently an integrated development environment called Xcode. Xcode provides interfaces to compilers that support several programming languages including C, C++, Objective-C, and Java. For the Apple Intel Transition, it was modified so that developers could build their applications as a universal binary, which provides compatibility with both the Intel-based and PowerPC-based Macintosh lines.

Apple introduced many new features with each new release of OS X. One of the major differences between the previous versions of Mac OS and OS X was the addition of the Aqua GUI, a fluid graphical user interface with water-like elements. Furthermore, every window element, texts, graphics or widgets was drawn on-screen using the anti-aliasing technology. ColorSync, a technology introduced many years before, was improved and built into the core drawing engine, to provide color matching for printing and multimedia professionals. Also, drop shadows were added around windows and isolated text elements to provide a sense of depth. New interface elements were integrated, including sheets (document modal dialog boxes attached to specific windows) and drawers.
The human interface guidelines published by Apple for Mac OS X are followed by many applications, giving them consistent user interface and keyboard shortcuts. In addition, new services for applications were included, which included spelling and grammar checkers, special characters palette, color picker, font chooser and dictionary; these global features are present in every Cocoa application, adding consistency. The graphics system OpenGL composites windows onto the screen to allow hardware-accelerated drawing. This technology, introduced in version 10.2, is called Quartz Extreme, a component of Quartz. Quartz's internal imaging model correlates well with the Portable Document Format (PDF) imaging model, making it easy to output PDF to multiple devices. As a side result, PDF viewing is a built-in feature.
·Version 10.4 - include Automator, an application designed to create an automatic workflow for different tasks; Dashboard, a full-screen group of small applications called desktop widgets that can be called up and dismissed in one keystroke; and Front Row, a media viewer interface accessed by the Apple Remote. Moreover, the Sync Services were included, which is a system that allows applications to access a centralized extensible database for various elements of user data, including calendar and contact items. The operating system then managed conflicting edits and data consistency.
·Version 10.5 - all system icons are scalable up to 512×512 pixels, to accommodate various places where they appear in larger size, including for example the Cover Flow view, a three-dimensional graphical user interface included with iTunes, the Finder, and other Apple products for visually skimming through files and digital media libraries via cover artwork. This version includes Spaces, a virtual desktop implementation which enables the user to have more than one desktop and display them in an Exposé-like interface. Mac OS X v10.5 includes an automatic backup technology called Time Machine, which provides the ability to view and restore previous versions of files and application data; and Screen Sharing was built in for the first time.
Finder is a file browser allowing quick access to all areas of the computer, which has been modified throughout subsequent releases of Mac OS X.
Quick Look is part of Mac OS X Leopard's Finder. It allows for dynamic previews of files, including videos and multi-page documents, without opening their parent applications.
Spotlight search technology, which is integrated into the Finder since Mac OS X Tiger, allows rapid real-time searches of data files; mail messages; photos; and other information based on item properties (meta data) and/or content. Mac OS X makes use of a Dock, which holds file and folder shortcuts as well as minimized windows. Mac OS X Architecture implements a layered framework. The layered framework aids rapid development of applications by providing existing code for common tasks.

Audeo NeckBand Voicless Phone Calls
This is one of the latest new input devices. It is a neckband that translates thought into speech. The Audeo sensor is a highly integrated, extremely sensitive sensor of neurological activity. It noninvasively detects electrical activity at the sur
face of the skin. The Audeo actively processes this activity to make it a robust control signal. This control signal can then be connected to a speech engine in various ways to give back to a person, the ability to communicate. By interpreting and picking up nerve signals has been used to demonstrate a voiceless phone call. The name of this device is think n spell. Some scientists at Ambient Corporation are bent on improving their "Audeo" wireless neckband which taps into nerve signals being sent to the vocal chords and vocalizes those "thoughts" for you. Users have to specifically think about voicing words for them to be picked up by the band, but it saves them from saying potentially sensitive things while on a cellphone in public. The device is also being aimed at those who have lost the ability to speak due to diseases. Currently the device can only recognize roughly 150 words and phrases, and has a decent delay between "speaking" with your mind and the computer vocalizing the words for you though it still needs upgrade. This device can make the current communication technology take a step forward. This device can also be used for military purposes because of its stealth features the device can be used by the SWAT forces in America for surprise tactics instead of the hand sign ways.This device was introduced by Michael Callahan in the USA. The process of this device is from the neurological transmissions or vibrations it transforms into audio then it encrypts the vibrations with the audio then it transmits it into the cpu of the device then it sends a signal to the phone or to another device and by that they can communicate with each other.

Mini Hot Printer
But with Dell’s Wasabi PZ130 pocket-size printer you can quickly give your photo subjects and friends something more tangible in the form of a physical picture.
The 7-ounce Wasabi measures just 4.8 x 2.8 x 0.9 inches and produces 2-x-3-inch borderless color prints in under a minute. It uses an inkless printing process called Zink, and Dell offers photo paper in either a 24 pack for $12 or a 48 pack for $20. Plus, the paper comes with a sticky backing so that the photos can be used as stickers for things like scrapbooking and tagging bags and belongings.
The Wasabi printer works with Bluetooth phones so that you can wirelessly print pictures, and it also has a PictBridge connector for printing directly from compatible digital cameras. Dell claims that the printer is easy and intuitive to use, with simple buttons and indicators. And for a limited time, Dell is also making it easier to buy with a price of $99; it regularly sells for $149.
Get Wasabi while it’s hot.
