Future Touch Tech

This concept computer-of-the-future by designer Jakub Záhoř allows the user to operate the device anywhere they can find a glass surface. The user simply attaches the central unit to any glass surface like a window or coffee table, switches on the power, and watches their system light up before their eyes. The display appears as an interactive hologram on the glass that the user merely has to touch to operate. It also makes for an easy, take-anywhere way to project photos and presentations or stream movies.

The concept relates to a device the size of a smartphone with a unique touch button that acts as ON / OFF switch. This device is to be a mini-computer that works in a particular way. Indeed, it must be installed on a glass surface to be functional. This done, the user only has to turn it on by pressing the switch. The device then scans the surface before use as touch interface. A virtual office will be posted on the glass surface and the user can work on his newly created job. The screen and keyboard projected onto the glass are 100% multitouchs. Whether this technology will see the light of day in the future in any case, the concept is worth a look.

What is RSS Feeds?

Want to know what all this RSS talk is about? Learn how to harness it and use it to your advantage.

The Internet is a big place. Really big. With over a billion existing pages and thousands more being created each day, there’s a lot of great sites with a lot of fantastic content out there. But with such a massive torrent of media being produced each day, it can sometimes be hard to keep up with all your favorite sites. So how do we alleviate this problem? The answer is simple — really simple in fact. Here’s a really simple explanation of Really Simple Syndication (RSS).

What is RSS?

RSS is a notification system that alerts you when updates are made to your favorite sites. It allows content to be sent to your computer without you having to seek it out and visit an actual website. Think of it like TiVo, but for the Internet. Essentially, the Internet is like TV, but with a zillion different channels to choose from, so rather than channel surfing for hours on end, you can use an RSS aggregator (more on this in a minute) to organize all your favorite content in an easily accessible format. Like TiVo, you just tell it what you want to record, and it sends it to your computer for later viewing.

How does RSS work?

Rather than paying upwards of 100 bucks for a DVR like TiVo, you can start using RSS for free — all you need is a Internet connection and a program called an RSS aggregator. An RSS aggregator, also known as feed reader, is a program that runs in the background and constantly waits for your favorite sites to post new content. When something new pops up on a site you’re subscribed to, it gets sent to your feed reader instantaneously. Typically, aggregators come in two varieties; they can be Web-based or desktop-based. There are also a number of programs and add-ons that give RSS functionality to e-mail clients and browsers. Once you’ve installed a feed reader, you can get started.

How do I use RSS?

There are hundreds of aggregators out there, with all kinds of different interfaces and useful features, so finding one you like is just a matter of experimentation. We recommend starting with Google Reader, simply because almost every other aggregator you can find out there is capable of syncing with it, so if you find another program you like better, you can easily import all your feeds. Plus its Web-based, so you can access it even when you’re not at your home computer.

Once you have an aggregator (aka feed reader) installed, you can start subscribing to your favorite sites. Generally, you’ll know if a site supports RSS subscriptions if it has an orange icon that looks something like this

These days, you’re likely to be hard pressed to find a site that doesn’t support RSS. Most sites have buttons that you can click to receive updates on Twitter or Facebook, and the RSS button is often located right next to these.

RSS tips and tricks

If you’re using Google Reader, there are various browser extensions that make subscribing to feeds a snap. Google Chrome users can use this extension, while those who favor Firefox can use this, and Internet Explorer fans can install this to add one-click subscriptions to websites.

For power users

RSS can be used for more than just news, music, and videos. Sites like Craigslist and eBay support RSS subscriptions to specific categories of services and items. Looking for a fridge, a welding job, or a three-bedroom apartment? Just type in your search terms and scroll to the bottom of the page. At the bottom right, there should be a button that allows you to subscribe to that list of classified ads, and be alerted when any new posts are published.

In summary, RSS is a fantastic way to organize and consume the Web with increased efficiency and ease. If you do most of your reading on the web, a sturdy RSS reader is a must-have. Also, be sure to check out Digital Trend’s RSS feeds for some of the best content on the Web!

Java - an Intro

Java - an INTRO

What is Java?

Java is:

Object Oriented
Platform independent:
Simple
Secure
Architectural- neutral
Portable
Robust
Multi-threaded
Interpreted
High Performance
Distributed
Dynamic

Java Environment Setup:

Java SE is freely available from the link Download Java. So you download a version based on your operating system.

You can refer to installation guide for a complete detail.

Java Basic Syntax:

Object - Objects have states and behaviors. Example: A dog has states-color, name, breed as well as behaviors -wagging, barking, eating. An object is an instance of a class.

Class - A class can be defined as a template/ blue print that describe the behaviors/states that object of its type support.

Methods - A method is basically a behavior. A class can contain many methods. It is in methods where the logics are written, data is manipulated and all the actions are executed.

Instant Variables - Each object has its unique set of instant variables. An object's state is created by the values assigned to these instant variables.

First Java Program:

Let us look at a simple code that would print the words Hello World.

public class MyFirstJavaProgram{

/* This is my first java program.
* This will print 'Hello World' as the output
*/

public static void main(String []args){
System.out.println("Hello World"); // prints Hello World
}
}
