Utility Part 3 {mobiles} ::::


1.How to Activate WhatsApp Voice Calling

 

WhatsApp's voice calling feature is now available to all Android users. The world's most popular messaging app with over 700 million monthly active users only introduced this feature recently and rolled it out gradually to its Android users. If you are not an Android user, you'll just have to wait a little longer to get this feature. But if you use Android, and haven't yet activated voice calling on WhatsApp, what are you waiting for?
The process isn't as simple as updating WhatsApp to start using the voice calling features. It involves a couple more steps that you need to follow. We've described these below, so take a look to enable voice calling on WhatsApp for Android.
  1. Download the latest version of WhatsApp for Android from here. The latest version on WhatsApp's website is 2.12.7, but if you're downloading from Google Play, ensure that your device has version 2.11.561. Older versions don't support this feature for all users.
  2. Once you have the latest version of WhatsApp installed on your Android phone, ask someone who has WhatsApp calling enabled to make a WhatsApp call to your number.
  3. Multiple users have reported that giving a missed call doesn't work. You'll have to receive the call and wait for a few seconds before disconnecting to activate WhatsApp voice calling.
  4. When the feature is enabled on your smartphone, you'll see a new three-tab layout on WhatsApp, one each for Calls, Chats and Contact



     

2.Android Essentials::

 

 

1. SwiftKey

Android Must-Have Apps: SwiftKey
There are tons of great Android keyboard apps around, but SwiftKey has been my go-to typing tool for a long time. Its combination of personalized next-word prediction and slide-to-type functionality makes it a perfect fit for my typing style -- and its newly introduced cloud-sync option means my customized setup appears on any device I use within seconds of installation.
2. Google Voice
It may be in the midst of a transition to Hangouts, but for now, Google Voice is an absolute must-have on any phone I'm carrying. My main phone number is a Google Voice line, so once I have the GV app installed, I can make and receive both calls and texts on the device using my own personal digits.
Especially as someone who moves around among multiple devices, that's an invaluable kind of power to have.
3. Google Drive

Google Drive
Regardless of where I'm working, I use Drive and its Google Docs component as my sole word processor and spreadsheet editor. With the Drive app on my phone, I can quickly view and edit any notes or documents I've created and the changes are synced instantly to my account. That means they appear in real-time on any PC or Chromebook where I also have Docs open and are waiting for me the next time I open Docs on any other device.
4. Dropbox
Even though its functionality overlaps with Google Drive, I still use Dropbox for certain types of storage, file syncing and cross-device transfers (the first rule of life in the cloud is never to keep all your eggs in one basket, right?). Having the Dropbox app on my phone makes it easy for me to get at my stuff and upload new files as needed.

Android File Manager
5. Sliding Explorer
File managers let you use your Android device just like a computer -- browsing through storage, finding and dealing with specific files, and sharing files directly to other installed services. I recently made the switch over to Sliding Explorer as my go-to file management solution; it's simple, easy to use, and has a clean user interface that adheres to current Android design guidelines (which is a major plus in my book).

6. Reader+
Google Reader may be gone, but for me, RSS remains the easiest way to keep up with all the news I need to follow during the day. Reader+ is my favorite app for doing it: It works seamlessly with Feedly and offers a highly customizable, easy-to-use interface along with an excellent in-app browser. It's hands-down one of the most frequently used apps on any device I carry.
7. Twitter
I've used a lot of Twitter clients over the years, but I've recently -- and somewhat reluctantly -- settled on the official Twitter client for my current on-the-go tweeting needs. Though it got off to a rough start, the official Twitter app now boasts a clean and simple interface, provides multiple account support, and does pretty much everything I need in a lightweight package. And, in contrast to most of the third-party alternatives, it's not in a constant state of battle to stay alive (grumble, grumble, grumble).

8. Simple Calendar Widget
I rely on Google Calendar to keep myself organized, and having my upcoming appointments and events on my home screen is a key part of how I keep tabs on my agenda. The stock Android Calendar widget doesn't quite cut the mustard for me, nor do most of the manufacturer-added alternatives, but Simple Calendar Widget is exactly what I need.

Simple Calendar Widget
Simple Calendar Widget's customization potential is what makes it numero uno for me: After I download my saved settings from Dropbox and unzip them using Sliding Explorer (see what just happened there?), the widget looks just the way I want it -- with a long-reaching scrollable list of my agenda and no added frills.

9. HD Widgets
While there are plenty of good Android weather widgets out there, HD Widgets' minimalist design and high level of customizability make it the one I want to see on my home screen. Its presence goes a long way toward making a phone feel like my own.
10. Pandora
All productivity aside, my phone is also my workout companion. I use Google Music for storing and streaming my own stuff, but when I get in the gym, Pandora's almost always the app I open. After years of ongoing tweaking, I have a handful of stations on it that play an awesome mix of (almost exclusively) songs I want to hear.
11. Netflix
Now that I'm using Chromecast for all my Internet-to-TV streaming needs, the Netflix app is a core piece of my Android arsenal. I have my phone within arm's reach more than any other gadget, and the Netflix app serves as my remote for sending shows to the telly and controlling playback once they're there.
12. Nova Launcher (and Nova Launcher Prime)
When I'm testing a phone for review purposes, I tend to use its own launcher -- at least initially -- so I can get a feel for its default user experience. When I'm using a device long-term, though, a custom launcher almost always comes into play.
I go back and forth between a lot of different launchers -- and there are quite a few that I really enjoy -- but Nova is the one I usually come back to in the end. I like it because it lets me have a stock-like experience with a handful of tweaks and added elements, like more on-screen space, custom swipe- and tap-based gestures, and sped-up animation performance.

YU Project Caeser ::::

It looks like YU, the recently launched smartphone brand from Micromax, is gearing up to launch a new smartphone.

The firm has already started teasing a phone which has been code-named Project Caesar. The latest teasers on the company's Facebook page suggest that the phone will come preloaded with Android Lollipop, the latest version of Google's mobile OS.

YU has even taken a dig at Xiaomi in a teaser that reads, 'KitKat in the age of lollipop? Give ME a break.' Interestingly the 'ME' in the teaser resembles Xiaomi's 'Mi' logo. It's worth pointing out that Xiaomi's recent flagship, Mi 4, comes preloaded with Android 4.4 KitKat and not Lollipop.

YU is rumoured to release the new smartphone in April. This is also the time when Cyanogen, which powers the software of YU smartphones, is expected to release a build based on Android Lollipop. No other details related to the phone are available at the moment. The company had earlier launched Yureka, a budget phone that offers mid-range specifications and is sold via weekly flash sales.
The first phone under Micromax's Yu brand has been launched in India. The device, known as the Yureka, is going to be available from tomorrow, exclusively on Amazon. The company is following a flash sale model, where consumers will have to register for the devices and then take part in the sale. This means that you will be able to register from tomorrow, while the device actually goes on sale on January 8.

Micromax quickly responded to Xiaomi's fame with a new brand called Yu that is aimed at growing tech enthusiasts in India. Mimicing Xiaomi's flash sales and online sales model, the company launched its first Yu Yureka smartphone, priced under Rs. 10,000. And now the company is gearing up to launch its next Yu smartphone in India. - See more at: http://www.digit.in/mobile-phones/micromax-announces-project-caesar-hints-at-lollipop-based-yu-phone-25550.html#sthash.sFaQn4Ee.dpuf

USB 3.0

USB 3.0
USB 3.0 LogoUSB 3.0 is the third generation of USB (Universal Series Bus) technology that acts as a connector between a host computer and peripheral devices. The name SuperSpeed comes from the higher data transfer rate which greatly exceeds the previous standards of USB 1.1 and USB 2.0.
These external yet integral peripheral devices include but are not limited to: keyboards, monitors, printers, cameras, flash drives, gaming consoles and smartphones.
Like the earlier formats, it can link devices and computers without needing to first power down the computer. USB 3.0 is designed to not only streamline function of peripherals with PCs, but to do so with ten times the bandwidth. Developers at Intel announced the forthcoming release of USB 3.0 in 2007 with specifications and compatibility details underway in 2008 and 2009. The first devices equipped with USB 3.0 technology debuted in the commercial market in 2010.
SuperSpeed will likely not have complete mainstream operating system support until its developers at Intel release the motherboard chipset inherent to computer operation until 2012. It was originally slated for release more than a year earlier. However, it is speculated that competitors like AMD may attempt to integrate the USB 3.0 chipset into their technology a year ahead of Intel.
USB 3.0 SuperSpeed is designed to keep up with the pace of increased demands in consumer storage for more bandwidth for components including: high definition audio and video, increased megapixel data on cameras, smartphones with dozens of gigabytes of storage capacity and high-volume storage devices like Blu-ray drives. At USB 2.0’s optimum speed of 480 megabits per second, it may simply not meet the speed potential required by these devices.
In theory, the top speed throughput of USB 3.0 is 4.8 gigabits per second due to improved connectors and cables. Although it may not reach this transfer rate, just half of this transfer rate equates to the aforementioned bandwidth that is ten times faster than its predecessor. The USB 3.0 cable contains four extra wires compared to 2.0 to carry data information in a bidirectional manner. Considering it in terms of traffic, it simultaneously allows download and upload capabilities to travel through the cables without slowing due to data overload.
Power efficiency is another noted feature of USB 3.0. It can operate in three different modes to safeguard against excess energy use. Unlike USB 2.0—which had to continuously poll both active and idle devices for data information—the SuperSpeed interface signals the host computer or server for data transfer, therefore conserving power.
Users will be able to experience more power capabilities for configured devices as well as those not yet modified for setup. The Type B plug that enters into a device and the receptor carry an extra set of connectors to cut down on power demands for an item such as a wireless adapter. Consequently there is no reliance on a supplemental power source.
Backward compatibility is also possible with SuperSpeed. The actual connector maintains its dimension and form so that the additions of more internal wires to the design—which look like an extra metal fold—only need to be employed when linked to a 3.0 connection. As a result, USB 3.0 cables are incompatible with 2.0 devices, but USB 3.0 devices and cables are compatible with computers that have USB 2.0 ports.

USB 2.0

USB 2.0 (Universal Series Bus 2.0 version) is the second generation interface of computer technology that consists of a group of input and output wires with a port connection that transfer data at a higher speed than its predecessor, USB 1.1.
USB 2.0 brings a high speed connection to electronic peripheral devices like external hard drives, printers, cameras, flash drives, keyboards, gaming consoles, MP3 players and smartphones to a computer.
As a result, the computer will operate the device or display its data contents. It is intended to streamline the use and compatibility of external devices with PCs. This USB version debuted in 2000 and was standardized in 2001. A computer’s USB 2.0 connection location is commonly identified by a stylized trident symbol at the front or back of the computer tower and is compatible with Windows, Mac and Linux systems.
Its bandwidth is calculated at a rate of up to 480 megabits per second, rendering its speed to be far superior to USB 1.1’s 12 megabits per second. However, USB 2.0 can accommodate a total of three speeds. Low speeds of 1.5 megabits per second accommodate keyboards and speakers whereas the highest speed transfers data for devices like printers and hard drives. To determine which USB connection a computer supports, search the control panel and subsequently the hardware settings and expand the Universal Series Bus column.
The USB 2.0 system has a host (computer or server) containing several ports that allow for computer peripherals. Next, endpoints—which are register mechanisms that act as descriptors to interpret data transfer information—connect the peripheral devices to the host via pipe channels. A pipe can operate in one or two directions as the actual connection between host and endpoints. USB 2.0 polls the device in order to send data.
A pipe channel will implement one of four types of data transfers: interrupt, isochronous, bulk and control. Interrupt transfers are used for devices like keyboards that need instant responses and isochronous ones will experience potential loss of information with the transfer of something such as audio or video and allow for guaranteed bandwidth. Bulk transfers are used to pass files with the bandwidth at hand. Control transfers are bidirectional pipe channels used for simple command and status operations initiated by the host. For USB 2.0, the controller of the host will continuously sample activity from the input and output wires, or bus. The peripheral device at the lowest speed will determine the bandwidth.
USB 2.0 has experienced some adjustments and minor updates to optimize function. Among these changes: more interfaces for some peripheral devices, new plugs to enhance connector longevity, the ability for a USB to function as a host for a secondary device and USB host chargers.

2.Create an AutoRun File for a USB Flash Drive

about:-     

USB AutoRun is the term used when specific, predetermined digital content is automatically launched from your flash drive as soon as it is plugged into a memory port. The content can include items like a web page, interactive menu, multimedia presentation, a document, or an entire application. Creating an autorun USB drive allows for customization of content as well as the personalization of the title of your flash drive and its autoplay setup options.

Flash drive autorun has two primary purposes. First, it helps the user navigate the contents of the device with ease—a menu will quickly display all of the drive's files without any prompting on your part. Second, when the USB drive is distributed as a promotional gift, it provides a second layer of marketing on top of a branded exterior. The USB autorun can deliver web pages, commercials or special offers without the risk of users missing it or having to search for the flash drive's contents on your desktop or buried in My Computer settings.

NOTE: Keep in mind that Mac operating systems cannot use autorun, and it is believed they do so as a general security measure. Also Windows Vista and Windows 7 users are not initially set up for the command, but have the option to manually turn on autorun from the control panel.

If you are working with a large quantity of flash drives, a custom USB duplication service can quickly handle your autorun needs. However, creating an autorun flash drive from the comfort of your own PC or laptop is also possible.

First, you will need to open the text/HTML editor, Notepad, to make USB autolaunch work. The program is intended to provide a clean slate for the creation of code. You will also need your executable application or document you are wanting to open. Once in Notepad, type out the following text:



STEPS TO CREATE :





Then, save your Notepad file as autorun.inf under the flash drive's root directory. Make sure you don't have any spaces or illegal characters in the filenames so that they open properly.

If you feel like getting a little fancy, you can even add more like a company icon or use a long label to name the drive:
[autorun]
Icon=MyLogo.ico
Label=My long drive name here
;Open=PlayMe.exe
ShellExecute=PlayMe.exe
UseAutoPlay=1




 Here is how it would look copied onto your USB Drive. You may need to change the .ico file properties to Hidden to allow your autorun to work properly on most PC machines so Windows won't try to open them in a picture viewer.

Top 10 Computer Tricks Every Geek Should Know


We've talked before about the things every computer user should know how to do, but we geeks are special: we want to go above and beyond, to explore every nook and cranny of our system and make everything easier. Here are ten ways to do just that.

1. Program Your Own Dead Simple Scripts
You don't need to learn an entire programming language to write advanced scripts. Windows users can do a ton of awesome stuff with AutoHotkey, from creating simple keyboard shortcuts to controlling their PC remotely. To get started, just check our beginner's guide to AutoHotkey and our list of the best AutoHotkey tricks. Mac users don't have anything quite like AutoHotkey, but you can do quite a bit with the built-in, insanely easy-to-learn AppleScript. If you aren't the coding type, check out Automator on the Mac and its clone, Actions on Windows

2. Squeeze More Power Out of Your Hardware
With a bit of tweaking, you can push your hardware past its original limits and get some pretty serious bang for your buck. When it comes to your PC, you can overclock your processor and video card, and even install OS X on non-Macs by building a Hackintosh. And, while you're at it-even though it isn't a computer trick specifically-you should try turning your $60 router into a $600 router with DD-WRT.

3. Run a Basic Linux Distribution
Even if you don't want to switch operating systems, knowing a few Linux basics can be really handy. With a live CD on hand you can troubleshoot your machine, revive an old, slow PC, and make your way through Linux-based DIY projects. Check out our five-part guide to getting started with Linux, and be careful-it can be quite the rabbit hole once you get into it!

4. Navigate Everything With Your Keyboard
There are certain basic keyboard shortcuts everyone should know, but if you really want to use your computer more efficiently, you can take it so much further. Learn the most common shortcuts for your favorite programs, like Gmail, Microsoft Word, basic text boxes, and even Facebook. After a little while, you'll be able to blow through menus and text boxes with unbelievable speed. Check out our guide to becoming a keyboard ninja, complete with a bunch of cheat sheets to help get you off the ground.

5. Learn to Crack Passwords (and Protect Yourself)
Everyone should know how to create a secure password, but responsible geeks can take it a step further by learning how to break into a comptuer. This skill-whether used on a Windows machine or a Mac-can really help you understand how computer thieves and hackers will try to get at your data. Learning the process means you know how to protect yourself against the process-not just with strong passwords but with encryption and other settings tweaks that keep thieves out. Similarly, you may also want to learn how to crack a Wi-Fi network's WEP and WPA password.
6. Know Your OS's Hidden Features
Every operating system has hidden things lying under the hood, you just have to know where to look. Windows users should check out the hidden features of Windows 7 and Windows 8, while Mac users should peruse the hidden features of OS X Lion and Mountain Lion. If you want to find even more, you can often find them in Windows' Registry or in OS X's terminal. System tweakers like Ultimate Windows Tweaker, OnyX for Mac, and Ubuntu Tweak are also great places to find secret features.

7. Run Everything on a Schedule
Stop performing all that system maintenance yourself and set it all up to run on a schedule. With Windows' built-in Task Scheduler, you can run just about any kind of task-whether it's maintenance, picture uploads, or even a simple alarm-through Windows' built-in tools (in fact, it's one of the best Windows 7 features you've probably forgotten about). Mac users looking for something similar should check out Tasks Till Dawn.

8. Read and Understand Your Resource Usage
When your computer starts acting a little slow, a lot of people jump to their resource monitor to see what's causing problems. However, just looking at a bunch of charts and graphs isn't going to tell you what's wrong unless you really know what you're looking for. High CPU is a common problem with one app slowing your system down, and as soon as you close it, the issue should go away. High network activity could be the cause of slow internet or slow file transfers over the network. RAM usage, however, is where a lot of people get thrown off: high RAM usage isn't inherently a bad thing. Know the difference between good and bad RAM usage before you start blaming processes. If you want to keep an eye on your resources, check out our favorite system monitors for Windows, Mac, and Linux, too.

9. Use the Command Line Like a Ninja
Using the command line isn't as exciting as it looks in the movies, but it can be a very useful tool (in fact, some tools are just better in the command line). It's pretty easy to learn, too-check out our command line primer for beginners to learn some basic commands. Once you've got that down, read up on the best shortcuts that help you navigate the command line like a ninja. Those guides apply to UNIX-based systems like Linux and OS X, but if you're a Windows user you can grab something like Cygwin to get a similar experience (or, if you want a more Windows-centric tool, try Powershell).

10. Find New Uses for the Programs You Already Have
Chances are, you've probably already found a few awesome tools and added them to your productivity arsenal, but most programs can be used for more than just their inteded purpose. The file-syncing Dropbox, for example, is also great for monitoring your home computer, printing files from afar, and even downloading stuff with BitTorrent. Savvy folks can use Gmail to store files in the cloud or find out if someone's stolen your laptop. Any tool can become multipurpose if you know its ins and outs.
