How to format an unformattable pendrive?

Format an Unformattable Pen Drive with simple
DOS Command, Perhaps these days almost all of
us are well aware of pen drives and use them a
lot for files transfers from one PC to another or
sometimes use them to listen music or videos
stored on the flash drives. But sometimes the
excess use of these pen drives from one PC to
another results into infection with some rare
viruses which cause them to malfunction like
folders missing, capacity shown less or sometime
we even couldn’t format it.
The reason for such a problem a virus residing in
the pen drive makes the system busy so from
windows environment it becomes hard to format it
or access it properly. So below is the simple DOS
command thru which you can easily format a pen
drive.

 Go to Start –> Run.
 Type Cmd & press Enter.
 Type the following command line
 Format/x G:
 Here G: refers to your removable disk
 drive letter.
 Press Enter.

Now I hope your problem will be solved if in any
 case there is still a problem then I will advise you
 to download the best tool for pen drives “HP
 Format disk Utility” which is quite a very good
 application that can fix a lot of pen drive related
 problem

Create blur bitmap using RenderScript and ScriptIntrinsicBlur

ScriptIntrinsicBlur, added in API Level 17, is a Intrinsic Gausian blur filter. Applies a gaussian blur of the specified radius to all elements of an allocation.

Here is a example show how to create blur bitmap with RenderScript and ScriptIntrinsicBlur.

package com.example.androidimageview;

import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.renderscript.Allocation;

import android.support.v7.app.ActionBarActivity;
import android.widget.ImageView;
import android.widget.SeekBar;
import android.widget.SeekBar.OnSeekBarChangeListener;
import android.widget.TextView;

public class MainActivity extends ActionBarActivity {

 TextView textTitle;
 ImageView image1, image2, image3;
 SeekBar seekbarBlurRadius;
 
 Bitmap bitmapOriginal;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  textTitle = (TextView) findViewById(R.id.title);
  image1 = (ImageView) findViewById(R.id.image1);
  image2 = (ImageView) findViewById(R.id.image2);
  image3 = (ImageView) findViewById(R.id.image3);

  bitmapOriginal = BitmapFactory.decodeResource(getResources(),
    R.drawable.ic_launcher);

  image1.setImageBitmap(bitmapOriginal);

  // create blur bitmaps
  image2.setImageBitmap(createBitmap_ScriptIntrinsicBlur(bitmapOriginal, 25.0f));
  image3.setImageBitmap(createBitmap_ScriptIntrinsicBlur(bitmapOriginal, 25.0f));
  
  seekbarBlurRadius = (SeekBar)findViewById(R.id.blurradius);

  seekbarBlurRadius.setOnSeekBarChangeListener(new OnSeekBarChangeListener(){

   @Override
   public void onProgressChanged(SeekBar seekBar, int progress,
     boolean fromUser) {
    
   }

   @Override

    // TODO Auto-generated method stub
    
   }

   @Override

    float radius = (float)seekbarBlurRadius.getProgress();
    image2.setImageBitmap(createBitmap_ScriptIntrinsicBlur(bitmapOriginal, radius));
    image3.setImageBitmap(createBitmap_ScriptIntrinsicBlur(bitmapOriginal, radius));
   }});

 }

 private Bitmap createBitmap_ScriptIntrinsicBlur(Bitmap src, float r) {
  
  //Radius range (0 < r <= 25)
  if(r <= 0){
   r = 0.1f;
  }else if(r > 25){
   r = 25.0f;
  }

  Bitmap bitmap = Bitmap.createBitmap(
    src.getWidth(), src.getHeight(),
    Bitmap.Config.ARGB_8888);

  RenderScript renderScript = RenderScript.create(this);

  Allocation blurInput = Allocation.createFromBitmap(renderScript, src);
  Allocation blurOutput = Allocation.createFromBitmap(renderScript, bitmap);

  ScriptIntrinsicBlur blur = ScriptIntrinsicBlur.create(renderScript,
    Element.U8_4(renderScript));
  blur.setInput(blurInput);
  blur.setRadius(r);
  blur.forEach(blurOutput);

  blurOutput.copyTo(bitmap);
  renderScript.destroy();
  return bitmap;
 }

Home Automation For Dummies

The easy way to control your home appliances

Home Automation For Dummies
Do you want to control common household appliances and amenities from your smartphone or tablet, wherever you happen to be? Home Automation For Dummies guides you through installing and setting up app-controlled devices in your home, such as heating and air conditioning, lighting, multimedia systems, game consoles, and security and monitoring devices—and even suggests popular products to consider.

The saturation of the mobile market with smart devices has led to an upsurge in domestic devices, such as thermostats, refrigerators, smoke detectors, security systems, among others, that can be controlled by those devices. Both Google and Apple offer fully-integrated solutions for connecting mobile devices to home theater and audio systems, and now Google has branched out into smart thermostats and smoke detectors. If you've caught the bug and want to get your feet wet in this cool new phenomenon, Home Automation For Dummies gives you plain-English, step-by-step instructions for tech-ifying your home without breaking a sweat.

• Provides clear instructions on remotely controlling your home appliances
• Shows you how to set preferences to automatically adjust lighting or temperature
• Explores digital "life hacks" that explain how non-app-ready appliances can be controlled via smart phones using third-party go-betweens
• Covers an emerging segment of the industry that was one of the primary focuses of this year's Consumer Electronic Show

If you're looking to find new ways to simplify and better control your home environment using app-driven devices, your phone, or tablet, Home Automation For Dummies makes it easier.

Chinese Phone and Tablet Beginners User Guide: All Android Versions 4.0 Thru 5.0 Lollipop: Asus Cubot Huawei Iocean Jiayu Lenovo Oppo Oneplus Star THL Xiaomi Zopo ZTE & Others

Chinese Phone & Tablet Beginners User Guide: All Android Versions 4.0 Thru 5.0 Lollipop: Asus Cubot Huawei Iocean Jiayu Lenovo Oppo Oneplus Star THL Xiaomi Zopo ZTE & Others

This new guide is packed with all the essentials you will need, and contains almost 250 icons and illustrations to help a beginner use an android tablet or phone. The LOOK INSIDE feature previews extracts from throughout the guide, not only the beginning, to give you a better idea of the contents.

This new guide is covers all current android versions starting at version 4.0, released in 2011, right through to the latest version A.0, codenamed lollipop, which was launched in November 2014 and is being updated to millions of handsets.

There is also a section on leading Chinese phone models, advising website names, where you can obtain technical specifications and reviews, and some of the pitfalls of purchasing direct from China.

The guide is aimed at readers who have never operated any Android device previously, and is styled on my existing guide- Android User Guide for android versions 4.0 - 4.4 , which sold almost 900 copies through only two outlets in the last year with an almost 100% feedback. Feedback included words such as- a lifesaver, worth every penny, just right for beginners, well written, clear instructions, brilliant book. The most critical information, which a beginner needs, is explained in detail, click by click, generally in the order that the reader needs it, in the early parts of the guide, plus many links are provided to other external user guides for selected apps, which the reader can consult later. At the end of the guide is a three page summary of the icons and controls used in navigating the Android system, to serve as a reference chart for future use.

Most readers running version 4.4 KitKat will receive a free update to version 5.0, lollipop in any case, so this guide will give them a good idea of what to expect, when their device updates, and readers using the older versions of android- 4.0 - 4.3 will be able to get a feel for this brand new android version, if they are contemplating buying a new device.


ABOUT THE AUTHOR Having retired 2 years ago, after 30 years in export sales, marketing and IT, I looked around for something to fill in my time. I love technology and having owned countless unbranded Android smart phones, tablets and Android TV units, I felt there was a need for beginners' user guides, so I wrote this. I do hope that you will consider purchasing it. Thanks

Android Hardware Interfacing with the BeagleBone Black
About This Book

• Design custom apps that interact with the outside world via BeagleBone Black
• Modify Android to recognize, configure, and communicate with sensors, LEDs, memory, and more
• A step-by-step guide full of practical Android app examples that will help the users to create Android controlled devices that will use BeagleBone as hardware

Who This Book Is For
If you are an Android app developer who wants to experiment with the hardware capabilities of the BeagleBone Black platform, then this book is ideal for you. You are expected to have basic knowledge of developing Android apps but no prior hardware experience is required.

In Detail
This book explores using the Android OS on the BeagleBone Black hardware platform and provides an introduction to Android's unique approach to hardware interfacing. You'll be walked through the process of installing and configuring Android on your BeagleBone Black, as well as preparing your PC development environment to create Android applications that directly interface with hardware devices. Several example projects within this book introduce you to using the GPIO, SPI, and I2C hardware interfaces of the BeagleBone Black.

You'll create Android apps that communicate directly with actual hardware components such as sensors, memory chips, switches, and LEDs. Step-by-step guidance through both the software and hardware portions of these projects is provided. Combining all of the previous projects into a single project that uses GPIO, SPI, and I2C together, you will explore the details of creating an advanced hardware interfacing app. Finally, you'll be provided with information on transitioning prototype code into code suitable for deployment on an Android-based device. With a variety of example apps that demonstrate key hardware communication concepts, this book will help you become an Android hardware interfacing pro in no time.

How To Recovering Unallocated Space Of a USB Flash Drive??

How to remove unallocated space? 

• First of all run Windows command line and type diskpart in the command prompt.
• Windows will ask you for Administrator permissions to run the tool.
• Then run list disk command to find your USB flash disk’s number. It should be the same as disk’s number in Computer Management tool. It was I in my case.
• Next you should chose the disk to work with. Type select disk <disk number> command, e.g.select disk I. 
• The next step is to clean all volumes and partitions on the disk. Use clean command to do that. The last step is to create a primary partition.
• You can do that using create partition primary command. That’s all. You should be able to format your flash disk now.

This is how I removed unallocated space on my machine:

DISKPART> list disk

  Disk ###  Status         Size     Free     Dyn  Gpt
  --------  -------------  -------  -------  ---  ---
  Disk C    Online          298 GB      0 B

 Disk D    Online          298 GB      0 B

 Disk E    Online          298 GB      0 B

 Disk I    Online         7509 MB  6619 MB

DISKPART> select disk I

Disk 1 is now the selected disk.

DISKPART> clean

DiskPart succeeded in cleaning the disk.

DISKPART> create partition primary

DiskPart succeeded in creating the specified partition.

DISKPART> exit
