Google unveils Project Ara Spiral 2 modular smartphone

Google has revealed the Project Ara Spiral 2 modular smartphone. It features a 720p display, 5 MP camera and 3G connectivity.

Google revealed its prototype Spiral 2 modular smartphone at the Project Ara Developers Conference in Mountain View this week. The handset will be launched in Puerto Rico in the second half of this year.

The Project Ara Spiral 2 features Marvell PXA1928 and Tegra K1 dual application processors. It has a 720 x 1280 pixels display, speakers and a 5 MP rear camera. The modular smartphone will have inbuilt light and proximity sensors. Connectivity options included in the prototype are a microUSB port, 3G modem with band 2 Antenna, Wi-Fi, and Bluetooth support.

he Spiral 2 has a battery that offers 20% - 30% less capacity than an average smartphone, but Google plans to improve on that in the Spiral 3. According to reports, Google is already working on the Spiral 3, which will feature an improved camera, battery life, support 4G LTE connectivity and use an inductive system for contactless data connections between modules. 

Currently, the Spiral 2 has 11 modules, but Google plans to increase the number to 30 by the end of the year. The new modules will add 4G connectivity as well as an improved camera.

Google is planning to launch the device in Puerto Rico which will work as a smaller test market, while it works with the FCC on the project before launching the project widely. The Internet giant plans to sell the Spiral 2 chassis and modules in Puerto Rico in partnership with local carriers OpenMobile and Claro.

         Java (programming language) 

 

About & History :                                                                    

Java is a computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another. Java applications are typically compiled to bytecode (class file) that can run on any Java virtual machine (JVM) regardless of computer architecture. Java is, as of 2014, one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers. Java was originally developed by James Gosling at Sun Microsystems (which has since merged into Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.The original and reference implementation Java compilers, virtual machines, and class libraries were developed by Sun from 1991 and first released in 1995. As of May 2007, in compliance with the specifications of the Java Community Process, Sun relicensed most of its Java technologies under the GNU General Public License. Others have also developed alternative implementations of these Sun technologies, such as the GNU Compiler for Java (bytecode compiler), GNU Classpath (standard libraries), and IcedTea-Web (browser plugin for applets).

Compilers :                                                                                                                

Start off by making sure that you downloaded the Java JDK. This contains the Javac compiler which is a command line compiler. It is available here: http://java.sun.com/javase/downloads/wid... 

After that is installed, you can download and install an IDE called Netbeans which will allow you to edit your code in a more productive environment. You can get it here: http://netbeans.org/downloads/index.html 

Netbeans will only be able to compile your Java code if the JDK is installed. Be sure to install the JDK first.

Change IP Address Using Command Prompt

How to Change IP Address Using Command Prompt

Most everybody can figure out how to change their IP address using Control Panel, but did you know you can set your network card’s IP address using a simple command from the command prompt?

Changing IP Steps :

Changing your IP information requires two commands, one for your IP address, subnet mask and default gateway and another for  your DNS settings. In order to change your IP address we use the netsh command, the exact command you want to use is the following:

netsh interface ip set address name=”Local Area Connection” static 192.168.0.1 255.255.255.0 192.168.0.254

his assumes the following:

• The name of the interface you want to change the IP address  for is Local Area Network
• You want to statically assign an IP address of 192.168.0.1
• You want to set a subnet mask of 255.255.255.0
• You want to set a default gateway of 192.168.0.254

Armed with this information you should obviously switch the settings out for some that are suited to your network. You might, however, be wondering how you can go from using an already set static IP address to getting an address from DHCP. In this case the command you are looking for is:

netsh interface ip set address name=”Local Area Connection” source=dhcp

HELO FRIENDS,
Some time ago, I wanted to change the admin email of my blog, in the 
process, i made a very big mistake. When i added the second email, i 
thought it was all done, i went ahead and deleted the first email 
account while it was still my admin email. And the repercussion, i 
lost access to that blog. 
I know some people may be in the same situation. It may be that you 
have a Gmail account and hope to create a new Gmail address or you 
just want to transfer your blog to another email address probably 
because you don't like the present admin email. You must take care to 
do it so that you will not regret your actions later. Never delete an 
email account when it is still your admin email. By doing so you will 
inadvertently delete your blog and that is nearly impossible to 
recover. 




Transferring your Blogger blog from one gmail / email account to 
another is a very simple process if you do it correctly. 
To transfer your Blogger / Blogspot blog to a new email address, follow these simple steps correctly: 
1. Sign into your current Gmail account, i mean your admin email, the 
one you use to sign in to your blog. 

2. From your dashboard, select Customize > Settings> Permissions> 

3. Then select "Add Author." 

4. Add the new Gmail account as an author. 

5. Sign out of Blogger and Gmail. 

6. Sign into your new Gmail account. 

7. You will receive a message of invitation to be an author. Accept 
the authorship to your blog. 

8. Sign back into the first (admin) account. 

9. Go back to Customize> Settings> Permissions. 

10. Grant your new email address Admin Privilege. This will give both 
email addresses equal blogging control. 

You can now log in with your new admin email and control your blog with it. 

Now, if you wanted to delete the old email, take the following steps: 

1. From your dashboard, select Customize > Settings> Permissions> 

2. Then clicking "remove". This dissociates the email from your blog. 

Once you have severed the relationship between the email and your 
blog, your Gmail account can now be safely removed without losing your 
blog.
