My 4 reasons, Why java.

1. Write your code once and run it everywhere.
One of the biggest reasons why Java is so popular is the platform independence. Programs can run on several different types of computer, as long as the computer has a Java Runtime Environment (JRE) installed.

2. Practically 

It was designed to allow developers to get their job done with the minimum of fuss, whilst still enabling developers to pick up someone else’s (or even their own) code at a later date and understand what it’s supposed to do or work on it. Sure, you can write unreadable code in Java, just as you can in any language, but with good coding conventions it is more readable than many other languages.

 3. API

Java language itself is very simple. However, Java comes with a library of classes that provide commonly used utility functions that most Java programs can’t do without. This class library, called the Java API,is as much a part of Java as the language itself.

4. Easy to learn. 

the real challenge of learning how to use Java isn’t learning the language; it’s learning the API. The Java language has only 50 keywords, but the Java API has several thousand classes — with tens of thousands of methods you can use in your programs.

You don’t have to learn all of the Java API. Most programmers are fluent with only a small portion of it.

No computer repairer can trick you after reading this.

Some people that fixes computer might trick you and change some of your hardware, So...

In order to know if a computer repairer changed a piece of your computer's hardware you will have to do these few steps.

every piece in your computer has a unique serial number no other piece in the world has.

• How to know the serial numbers of your hardware pieces?.

checking for these numbers can be easy as installing a program called  "Belark" that analyses your hardware and gives a report that contains a lot of information including every piece's serial number.

• Make use of the serial number.

in order to check if a piece is changed, install the program and save the report before you computer crashes so you can compaire the serial numbers everytime you give your computer to get fixed.

Why everyone should learn programming?

Programming is not something used only by people who wants to work as developers for some company like facebook or google,  its something that gives you the ability to make things, things that you will need.
Today using a computer or a phone is so important, and some times you find your self having to do things over and over again, then you start thinking if there is a program that can do that job for you, and here comes your knowledge about programing,  if you know how to program then you can make your own application, for example lets say you own a store and everytime something is sold you will have to write it on a paper and at the end you will have to check for what products are sold and whats left,  what products you need to add to your store ect....
Then why not make the application that can tell you all of that just by you typing what is sold?
Did you get the point?

what is graphene ?

what is graphene ?

.
Graphene is made of a single layer of carbon atoms that are bonded together in a repeating pattern of hexagons. Graphene is one million times thinner than paper, so thin that it is actually considered two dimensional. 

In 2002, University of Manchester researcher Andre Geim became interested in graphene and challenged a PhD student to polish a hunk of graphite to as few layers as possible. The student was able to reach 1,000 layers, but could not hit Geim’s goal of 10 to 100 layers. Geim tried a different approach: tape. He applied it to graphite and peeled it away to create flakes of layered graphene. More tape peels created thinner and thinner layers, until he had a piece of graphene 10 layers thick. 

What makes Graphene so special?.

Graphene is one of the strongest materials known. It conducts heat better than diamond, and may conduct electricity better than silver. As it’s two-dimensional.

Graphene conducts so much electricity in so small a space that it may be used to develop miniaturized super fast computers and transistors. These devices should require a minuscule amount of power to support them.

Graphene is flexible, strong and transparent, too.
