Maths Magic-Proving 1 is equal to 100

In maths we learn that no any two numbers are equal but here we will prove that 1 is equal to 100

For this we will let suppose two identities x and y
here x=y(you can take the value if you want)
so x =y
so 99x=99y
so (100-1)x=(100-1)y
so 100x-1x=100y-1y
s0 100x-100y=1x-1y
so100(x-y)=1(x-y)   as here both sides(x-y) are same cancelling them
so 100=1

5 Nifty Apps That Turn Your Android Into A Universal Remote

With all the gadgets, remotes, and thingamajigs piling up on your coffee table, finding the right remote can sometimes be a real pain. But thanks to a few heroic Android developers, there are tools to consolidate some of those pesky remotes … into your Android phone. While you can’t use an Android app to turn your TV on or change the channels (because of the lack of an infrared emitter in the Android phones on the market today), the following apps let you control a home theater PC, Tivo, Squeezebox and other devices via your phone. And at the very least you can save a few bucks when it comes to media center accessories.
The following 5 apps are neat demonstrations of what you can do with a flexible, app-friendly phone like the Verizon Droid, the T-Mobile G1 or the Sprint HTC Hero.
1. RemoteDroid
This app transforms your Android into a wireless keyboard and mouse. It consists of 2 components: the RemoteDroid app on your phone and a server application for your computer. The difficulty level for set up is low; hop on a Wi-Fi network, run the server application and enter an IP address into the phone (the server app even displays it for you). Best of all, the app is free, so you’ll have that much more money towards a custom home theater PC.
2. Boxee Remote
It’s too bad you can’t call your lost, wee Apple remote when it’s disappeared and you know it’s gotta be around somewhere. But if you’re using Boxee, you’ve got a backup: The Boxee Remote app makes a great, free backup remote if you use Boxee as your primary means of streaming television and movies from your computer.
3. TivoRemote
A note to Tivo Series 3 and Tivo HD people: Forgetting to record your favorite shows on Tivo is a thing of the past. Put your medium-savvy tech hat on, dish out $1 and remotely control your Tivo from anywhere using Tivo’s Network Remote Control setting and TivoRemote. Since I don’t have a Tivo myself, I wasn’t able to personally test this application, but the reviews are positive and the community feedback are hymns of praise. One commenter on the market also found a ninja-like purpose for the pocket-sized remote, “My wife finds this highly irritating… thanks!”
4. SqueezeControl
SqueezeControl is a free app that taps into and controls your Logitech SqueezeCenter, a handy wireless network music player. We are all accustomed to lugging our phones around, so any app — like this one — that eliminates the fumbling of pockets for an additional device has a place in our world.
5. Gmote
Similar to RemoteDroid (and, like it, totally free), this app becomes a wireless keyboard and mouse for your computer or HTPC set up. It’s not too hard to set up: All you need is the phone app along with the server application on the computer you wish to use. Gmote pulls music, movies, and other media and organizes it all in convenient folders. In addition to it’s wireless keyboard/mouse functionality, it offers a remote control screen to quickly control your media.

How To Turn On Your PC With Your Android Phone Using Wake-On-LAN

If you’re a techie, one of the first things you do when you walk in the door is turn on your computer. Perhaps you simply tap your keyboard or mouse, or maybe you press the power button. Either way, you have to be at your computer before you can start it.
Wouldn’t it be easier if your computer was ready for you as soon as you sat down? If you own an Android device, that’s possible thanks to a free app called PC Auto Waker. The setup can be a little complex, but the payoff makes it worthwhile.

The Quick & Easy Setup

Once you’ve downloaded PC Auto Waker off the Android marketplace, you’ll need to set it up so that it has the ability to communicate with your computer. It depends on 802.11 WiFi, but it’s not necessary for each computer to have WiFi hardware. The PC you’d like to wake only needs to be connected to a broadcasting WiFi router.
The basic setup consists of three steps. First, you’ll need to enter a name for the computer you’re going to wake. This name DOES NOT have to be the same as the computer’s network name. This is merely a way of identifying the computer in the app’s interface.

After that, you’ll need to enter the MAC address of the target computer. Do a Windows Search for  ”cmd” to open your command line interface, then type ipconfig/all and press enter. The MAC address will appear as a string of six two-digit numbers labeled Physical Address.

Finally, you need to enter the SSID of the wireless network the target computer is connected to. It’s not necessary to enter any security information, regardless of whether the WiFi network is secured or not.
Once you’ve handled all of that, it’s time to see if you’re set! Place your computer into sleep or hibernate mode, and press the Wake All button in the PC Auto Waker app. If it works, great! If not, you have a few other settings to mess with.

The Nitty-Gritty Setup

If your computer did not wake it’s probably because the computer is not set up to accept a Wake-On-LAN packet. Fortunately, most computers can be configured so that they will accept it.

First, restart your computer and enter BIOS. This is done by entering the correct key at boot, which should be indicated on the POST screen that appears before Windows beings loading. Once you’ve entered BIOS, look for the Wake-On-LAN setting and enable it. You’re likely to find this along with other settings related to power management or networking, but BIOS vary from computer to computer, so you’ll have to do some digging of your own.

Once you’ve enabled Wake-On-LAN in BIOS, you’ll need to make sure Windows is configured properly as well. Do a Windows Search for Device Manager and open it, then navigate down to Network Adapters. Right-click on the one you use to connect with the Internet and then click Properties. On the Power Management tab you will find three checkboxes. If they’re not already checked, do so.
This should clear up any trouble that’s causing PC Auto Waker to malfunction.

Conclusion

PC Auto Waker is an awesome app. Once you have it set up, your computer will start as soon as your phone makes a connection with your WiFi network. This means you can walk in the door knowing that your PC is already starting. It’s magic!
What do you think about it?  Are there any similar Android wake on LAN apps that do a better job?  If so, let us know about them in the comments.

Version history of Android

Version history

Main article: Android version history

Android has seen a number of updates since its original release. These updates to the base operating system typically fix bugs and add new features. Generally, each new version of the Android operating system is developed under a code name based on a dessert item. Past updates included Cupcake and Donut. The code names are in alphabetical order (Cupcake, Donut, Eclair, Froyo, Gingerbread, Honeycomb, and the upcoming Ice Cream Sandwich).
The most recently released versions of Android are:

• 2.0/2.1 (Eclair), which revamped the user interface and introduced HTML5 and Exchange ActiveSync 2.5 support^[43]

• 2.2 (Froyo), which introduced speed improvements with JIT optimization and the Chrome V8 JavaScript engine, and added Wi-Fi hotspot tethering and Adobe Flash support^[44]

• 2.3 (Gingerbread), which refined the user interface, improved the soft keyboard and copy/paste features, and added support for Near Field Communication^[45]

• 3.0/3.1 (Honeycomb), a tablet-oriented^[46][47][48] release which supports larger screen devices and introduces many new user interface features, and supports multicore processors and hardware acceleration for graphics.^[49] The Honeycomb SDK has been released and the first device featuring this version, the Motorola Xoom tablet, went on sale in February 2011.^[50] Google has chosen to withhold the Honeycomb source code, which called into question the "open-ness" of this Android release.^[51] Google's Andy Rubin stated that the latest Android source code would be released "when it is ready". The reason for the delay, according to Rubin in an official Android blog post, was because Honeycomb was rushed for production of the Motorola Xoom.^[52] Google later confirmed that the Honeycomb source code would not be released until after it was merged with the Gingerbread release in Ice Cream Sandwich.^[53] The 3.1 update has been announced at the 2011 Google I/O on 10 May 2011.^[54]

The upcoming version of Android is:

• Ice Cream Sandwich,^[55] a combination of Gingerbread and Honeycomb into a "cohesive whole."^[56] It was announced on May 10, 2011 at Google I/O that it will be released in Q4 2011.^[57]

What is MOTOBLUR and what will it do to Android?

Though I do not consider myself to be a Motorola fan, it’s interesting to see the MOTOBLUR, a new customized version of Android OS, developed by Motorola, and probably its' biggest hope to revive some of the company's lost fortunes...
Visually, MOTOBLUR is a nice looking OS, with a clear focus on social networks. The home screen is holding all the popular social network feeds at screen (MySpace, Facebook, Twitter and of course emails) allowing easy reading and simple status posting.
It looks nice, but I guess it’s nothing more than another widgets styled fancy UI.

Motorola took Palm’s synergy vision and improved it a little bit: MOTOBLUR continuously (and automatically) syncs your phone and email contacts with your friends from Facebook™, MySpace and Twitter.
Beyond the homepage gimmick, all the feeds are listed in one unified inbox screen, which may become helpful.
Like Ping.fm, you can quickly update your status across all of these sites in one move. Other social networking features – like wall posts, photo sharing, and quick posting of videos to YouTube are also supported.
In addition, MOTOBLUR continuously updates and backs up the information into a secure environment. Again, not a real innovation, but a cool feature.
What’s going on behind the scenes?
Technically speaking, Motorola took the Android 1.5 source and customized it. Yes, that means that once you use Motorola’s MOTOBLUR, you are not running the version that was released by Google’s developers…
Is it a good thing to do?
I’m not sure.
Based on my previous experiences with Motorola user interface, I think that it’s better to stick with the original… maybe a customized shell (a-la Sense UI) is better, as it keeps the original source of the OS.
In any event, the first 2 devices to run MOTOBLUR will be: CLIQ (North America) and DEXT (International).
 
To see it in action (movies and some trials) check out the Motorola web site.

Use Your Android Phone as a Wireless Modem

Have a laptop but no Wi-Fi? Turn your Android phone into a modem and get your computer connected to the Net in seconds.

By JR Raphael, PCWorld    May 7, 2010 2:14 am

You know you can surf the Net on your Android phone--but did you know that the same phone can also enable you to surf the Net from your PC?
We're talking about something called tethering. In a nutshell, tethering allows you to use your smartphone like a wireless modem: You connect it to your computer, then use its 3G connection to get online.
Editor's Note: If you're phone is already running Android 2.2 (as of 7/27/10, its release is limited to the Google Nexus One only), you already have tethering built in to your phone. If you're running 2.1 or lower, read on.

Carrier Considerations

Before you start thinking about tethering with your Android device, you should check with your carrier to learn about its policies and conditions. Some carriers offer their own fee-based tethering services for certain phones; others forbid the practice altogether or assess penalties if they discover you're doing it.
As long as your carrier doesn't object, the only other consideration is data usage. While tethering, you'll be harnessing your phone's 3G connection to use the Internet from a computer, so you will be consuming a potentially sizable chunk of data. If your smartphone plan includes unlimited data, you should be fine; but if your plan allows only a certain amount of data per month, be sure to keep that restriction in mind.

First Steps to Tethering

Carrier-provided options aside, there are numerous ways to tether your phone to your laptop or desktop PC. Many of them require tinkering with advanced configurations on your Android device; we won't be getting into those here. The option we'll be explaining involves little more than installing a couple of programs and clicking on a couple of basic settings.
Let's begin with your mobile phone: Open up the Android Market and search for an app called PdaNet. Download and install it to your phone (it's currently available free of charge).
Once the app is installed, you'll need to download the companion program to your PC. Click over to June Fabrics (that's the name), and select the edition that's right for you. As of this writing, the program supports 32-bit versions of Windows XP, Windows Vista, and Windows 7; 64-bit versions of Windows Vista and Windows 7; and versions 10.5 and 10.6 of Mac OS.
Before you move on to the next step, you need to adjust one setting on your Android phone. From the home screen, tap the Menu key and select Settings. From there, select Applications, and then Development. Now check the box that says USB debugging. When the confirmation dialog box appears, press OK.
This setting allows the PdaNet app to stream data directly from your phone to your PC. It is a setting frequently used by developers. In theory, however, as the confirmation box explains, it could be used maliciously. For your protection, you should go back into this menu and disable the USB debugging setting whenever you are not actively using the tethering function.

Starting Your Connection

Take a deep breath--you're almost done. Plug your Android phone into an open USB port on your PC. Run the PdaNet app on your phone and select the Enable USB Tether option. The app will confirm that you've downloaded and installed its PC-based cousin; click Already installed to continue.
After verifying the connection, the app will tell you that it's on and running as a background service on your phone. Now, go to your PC and look for the PdaNet icon in your system tray--it's a rectangular box that looks like a cell phone. Right-click the icon and select Connect from the pop-up menu that appears.
At this point, everything should be all set (woo-hoo!). The PdaNet PC program should pop up a confirmation that you're connected, and a notification should appear on your desktop informing you that the PdaNet modem is up and running. Your computer is now online through your phone's data connection; you can open a Web page, check e-mail, and do practically anything else you could normally do while connected to the Net.
One final note: You may have noticed that the PdaNet Android app has a second option on its main screen: Enable Bluetooth DUN. If you're using a computer that has Bluetooth functionality, you can connect your phone to your PC wirelessly using this option instead of the Enable USB Tether option discussed above.

Video calling on iPad ,iPhone and Android

Mobile Video Calling is still not so affordable and many a times not utilized to full potential owing to restrictions and hurdles. Thanks to Apps, Smartphones today, allows free video calling over 3G / 4G / WiFi or simply any data connection.
Here I list some cross platform Applications for Mobile Devices which lets free voice calls and Live Video calls over any Data Connection.

Tango

Tango is quite new application and my favorite just because of its simplicity. You don’t need to make a profile either; you just install Tango, start it up and you’re ready to make video calls. Tango scans your Contacts and find friends who are already using Tango or you can also invite some from Address Book.
Tango works over both Wi-Fi and 3G and connects iOS (iPhone and iPod Touch) and Android devices. It’s easy to turn video on and off during a Tango call. Also, you can switch between Front Facing and Rear Facing Camera during calls. Visit Tango
I tried it on Airtel EDGE, Video Calling works but continuous streaming is problem, you get Still image many a times so 3G or WiFi is recommended.

Fring

Fring is another popular application which is also available for Nokia / Symbian Devices. Fring enables video calls between iOS and Android devices and works over 3G, but it requires you to create a profile and is a little more complex than Tango. Visit Fring

Qik

Qik allows you to connect over 3G and WiFi and works for both Android and iOS devices. As of now, Video Chat feature is limited to few Mobile Devices. Along with Video Calling, it supports Video Sharing called as Video Mail which are uploaded to your Qik Account. Visit Qik.
Data Charges apply as per your plan but still I would say it is far cheaper than Video Call rates implemented by Mobile Networks.

Recover and Copy Audio and Videos from Damaged Scratched CD DVDs

We know that CD’s and DVDs don’t lasts long and damages / scratches makes recovering data from them nearly impossible if we try to copy using Windows native functions.
This is irritating if we have our Photos and Video memories stored in optical Disks and not accessible after years due to scratches. Fortunately, we have a special program called Get My Videos Back which can copy and save Videos and Audio files from Scratched CDs and DVDs.

Get Back My Videos, in fact, is nothing but a freeware, portable, open source nature and specific to Windows OS. That Came into action, It Allows users data recovery Allocated on a CD, DVD and other types of optical media , Provided, However, That Whether audio or video file , These are the only files on the Which tool is Able to act.
Unfortunately, right now, Get Back My Videos can operate on a single media at a time (Well, Something is Better Than Nothing!) And, it also featured to copy bytes found and skip errors found.
You can customize speed of the recovery process and the elapsed time, then Which Allows the user to the Obtain an overall process.

Protect your stolen Mobile Phones

Protect your stolen Mobile Phones

Sometimes unfortunately your mobile phones gets stolen or sometimes it gets misplaced. So if your mobile phone gets stolen and it falls in hands of stranger then it can be a great threat to you.

Mobile phone contains lot of information like contact numbers, text messages (SMS), other data like games, videos, music files, emails etc. This information can be used by the robber or the person who founds your mobile phone. So we must know what to do if your mobile phone gets lost. Today we discuss about this fact.

First of you should avoid to store private/confidential information on your mobile phones. Many people save their bank account details, ATM pin codes, emails, etc in form of text messages or in any other form or in memory cards. So try to avoid such things. ;-)

Every mobile has an unique international code. This is 15 digit International Mobile Equipment Identity (IMEI) number of your phone that can be used to deactivate your mobile phone. You must remember this number. Usually this number is written on the packing box in which your bought your mobile. Just write this number somewhere and keep it safe. Now when ever your mobile phone gets lost or stolen you need to call the mobile phone company office and inform them about your loss, the company can then deactivate your mobile phone by using the IMEI number that you provided.

But this is not so much of use because the data in your mobile can still be still be accessed, however mobile phone will not work to perform functions like making calls, sending SMS etc.

So there is an alternative there are software available that can track your mobile phones. However this feature is now inbuilt in many mobile phones. But this software can provide you many features as below:

1. Locates your mobile phone using GPS.

2. Remotely locks the phone. You just need to send a SMS and your phones will get locked.

3. Remotely wipe all the data in mobile. You just send a SMS to remotely delete all data in mobile.

4. SIM card change alert. Receive an alert when ever SIM card on your mobile phone is changed.

So all these features can be used by using software. There are many such software available on internet. Google them to know more. I am providing you link of one software. This software's name is Sprite Terminator. Here is the link to know more about it:
