COZMO: HUMAN ENHANCEMENT TOWARDS AI ROBOTICS



Human brain is a box full of mystery. You never know what new idea may explode at your course of time . And what if that your idea turned out to be so intelligent that can often act and react like human. I am quiet sure reading these line one thing struck on your mind “robot”. Robot is a machine built to carry out some complex task or group of tasks which are programmed. It is one of that example of hard work and dedication of computer scientist since that era of time. And the concept of AI has brought their dream come true. Artificial intelligence has been arguably the most exciting field for robotics. Though its certainly the most controversial that a robot can work in an assembly line . But there's no consensus on whether a robot can ever be that intelligent as that of human brain. Indeed its an challenge for AI world that a man made machine with intellectual abilities as like ours. 

Today I am going to share about a creepy robot that’s fascinating today's world “COZMO”. Cozmo is an artificially intelligent toy truck which also shows the scope and future of AI and robotics. It is an artificially intelligent toy robot unveiled by San Francisco startup Anki- and Tappeiner. Cozmo is software driven that can be connected from device to device through Bluetooth. There’s no data in cloud so Cozmo is secure. It comes with three interactive power cubes, which the robot can recognize and with that you can play game such as quick tap, keep away or just free play. Cozmo is born to be playful; it is charming, mischievous, and unpredictable. It recognizes and remembers you, interacts with you, plays games and gets to know you over time. It combines the best of animation – humor, personality, and emotional connection with robots. 

Powered by advanced robotics, AI, and computer vision it has a brain that processes millions of data per second . It uses technologies such as computer vision, animatronics, motors and AI software. It has three ARM - based microprocessors running on android and iOS. 

Cozmo’s eyes changes color from blue to green when its mood changes. It can yawn, sneeze violently or shiver. The final design is made from 340 parts and it has four motors, a camera and a OLED display. When Cozmo is put on a charger, it goes to sleep and snores.

In this challenging world for AI this robot which can wake up, blink its eye, crawls has given life to the concept of John McCarthy.

A Day's power in half an hour: One plus 3T

Like it's said 'Life is a race.If you don' run fast you'll get trampled'. And here we are talking about the most important part of a human life 'A cell phone'. We all have studied that cell is the basic unit of our life,so is our cell phones😼.
Like we are dependent on our cell phones, our cell phones are dependent on their batteries. What if we run fast in our life but our phone doesn't? What if we have to make an important call and your phone shows a low battery? What if you want to capture the best moment of your life and damn battery is low again? I mean who wants that? We expect our phone to work at least for a day without charging. We all are living in a busy life and we have no separate time to let our phone charge for hours. Big Problem, right??

And here keeping these all things in mind One plus have created a sibling phone named as OnePlus 3T. As the name suggests, this device is essentially a souped up or 'Turbo' version of Oneplus that builds on everything we loved about the first while giving it a slightly more competitive edge against the competition.
Oneplus 3T comes with Dash charge. Dash charge is faster, safer, cooler and simply better than any other charging technology available today. Unlike other technologies, charging remain consistent even while gaming, live-streaming or demanding activities. The 3400mAh battery features a 13% increase in capacity over the Oneplus 3 which gives the solution to all the battery problem we face in our busy life. It take just half an hour to charge which will last all day long.

Not only the charger and battery life OnePlus 3T has Qualcomn Snapdragon 821(2.5GHz) which runs the most demanding apps and games with enhanced performance. 6 GB of RAM can juggle countless task without slowing down and internal storage of up to 128GB means running out of space is a thing of the past. And the camera of this phone offers 16 MP front and rear camera which gives you the crisp and sharp shots because of the cutting-edge noise reduction and improved stabilization technologies. Lightening fast shutter speed, snappy auto focus and intelligent software combine to create unmatched smartphone camera experience.

As far as the design is concerned, the OnePlus 3T looks exactly like its older sibling, and features the same full metal uni body construction, with a slightly curved back and rounded sides and corners. Despite being made entirely of metal, the phone is surprisingly light, and because the back tapers along the edges, it feels thinner as well, making for a device that is very comfortable to hold.

With a 5.5 inch with AMOLED display with 1080p resolution we get rich and vibrant colors with lot of contrast, and the optical dark mode that is built-in to Oxygen OS taking fantastic advantage of deep inky blacks. If you are not fan of vibrancy though, it is also easy to switch to sRGB color mode display setting that provides a more natural and less saturated look.

" PLAY MORE, DO MORE,STORE MORE" this awesome featured gadget costs $439 in today's date. So, if your looking for a phone with dash charge, camera that allows you to click in every angle with 1080p resolution then do invest it on OnePlus 3T.

7 Most Useful Quick Android Tips For Beginners

7 Most Useful Quick Android Tips For Beginners

We’ve been consistently coming up with various guides and tutorials for Android. If you haven’t still checked our beginner guide to basic Android settings, then you want to check them out because you might be missing 10 very useful tips to get most out of your Android device.
Moving on, here are seven most useful quick Android tips. These tips are definitely helpful to increase your productivity level, which includes disabling vibration during phone calls, taking screenshots, settings default dialer, optimizing phone screen, viewing saved wireless network password, hiding files and folders, and adjusting brightness using status bar.

TIP 1: HOW TO DISABLE VIBRATION DURING CALLS ON ANDROID

Whenever you get calls on your Android, by default the device rings along with vibration. This feature during calls is useful if you’re in a noisy place where its difficult to hear the ringtone; in that case the vibration might make you aware of incoming call.
But, vibration during calls is not always useful, so some of you might want to disable it. Disabling vibration might also save you some percentage of your battery charge.
On your Android device,
  • Go to Settings
  • Open Sounds
  • Scroll down to the Vibrate section and turn on/off Also vibrate for calls option
In this way you can now select your own preference during incoming call, either ring only or both ring & vibrate.

TIP 2: HOW TO TAKE A SCREENSHOT ON ANDROID

Do you want to share your score after getting a new high-score in a game, share portion of webpages, or share anything that’s on your Android screen? Whatever might be the reasons, you can simply take a screenshot to capture your Android screen and share it online or do whatever you’d want.
Taking a Screenshot on Android
  • Hold down Power button + Volume down buttons at the same time
  • Continue holding the buttons until you hear a click or a screenshot sound
To view screenshot
  • Visit Gallery app
  • You’ll find your screenshot image under Screenshots album

TIP 3: HOW TO SET THE DEFAULT DIALER IN ANDROID

Making an app default (selecting “always” options) means that the system won’t display any prompt to select an app the next time. One of my friend recently downloaded a dialer app from Google Play, and made that particular downloaded app the default dialer app to make calls. Now he wanted to revert back to the Android default dialer.
Well, there is an easy way to revert to the default one.
Visit settings > Applications > Manage Applications. 
Select the “downloaded” among the tab menu, to view the list of applications which you’ve downloaded. From the list select the dialer app which you’ve downloaded. Within the dialer app info page, scroll down and press the “clear defaults” button.
That’s it, now open the dialer, and this time you’ll be prompted to select an app to open the dialer.

TIP 4: HOW TO OPTIMIZE PHONE SCREEN IN CYANOGENMOD

LiveDisplay, one of the cool feature which CyanogenMod has added to their nightlies and I personally first came across this feature on OnePlus phones running CyanogenMod 12.1. LiveDisplay optimizes the phone screen based on time, providing various options including color temperature, brightness & saturations, enhance colors, screen color.
Viewing LiveDisplay Settings in CyanogenMod
  • Visit Settings
  • Select Display & Lights
  • Tap on LiveDisplay
Now let’s go through the available options which you can manipulate to optimize your phone screen.
Activating Night Mode in CyanogenMod
Visit Settings > Display & Lights > LiveDisplay, and tap on Display mode to select Night which automatically activates Night mode on your CyanogenMod phone.
Similarly, you can activate the Outdoor mode which optimizes the settings so that you can effectively use your phone while you’re outdoor, under bright sun.
Activating Automatic Screen Optimization in CyanogenMod
  • Visit Settings
  • Select Display & Lights
  • Tap on LiveDisplay
  • And select Automatic from the list of modes
Instead of selecting modes (day, night, outdoor), some might consider allowing the system itself to auto manage and optimize. No matter, which time you use your phone, the system automatically adjusts its settings.
Adjusting Screen Color of Your Phone Screen
While you’re inside LiveDisplay settings, visit Screen color option below Calibration. Here you can adjust the Hue, Saturation, Contrast and Intensity of the screen.
You have predefined settings: Standard & Vivid – available for adjusting Screen color.
If you want to manually adjust the settings select Custom, and tap the gear icon. Now slide the sliders as per your preference and once you’re done, tap SAVE button to apply the changes.

TIP 5: HOW TO VIEW SAVED WIFI PASSWORD ON ANDROID DEVICES

Sometimes you might forget the password of the Wireless networks (WiFi) which you’ve previously connected to. Once you connect to a network, your Android system automatically saves the network’s details, so that the next time you connect to the same network you won’t have to enter password again.
Logging into the router and viewing the wireless settings might be the first option, only if you’ve access to the router. What if its a public, or other networks (office/company) where you don’t have direct access to the router?  Well, in that case there’s a workaround that lets you view saved WiFi password on your Android device.
Disclaimer: Make sure that your Android device is already rooted.
  • Open Terminal Emulator on your Android device
  • Type su in the terminal to gain superuser access
  • Use cat command to view the content of /data/misc/wifi/WPA_supplicant.conf file.
cat /data/misc/wifi/WPA_supplicant.conf 
WPA_supplicant.conf files stores the details of networks which you’ve connected to.

TIP 6: HOW TO HIDE FILES/FOLDERS IN YOUR ANDROID DEVICE

Whenever we are forced to hang out with kids and relatives, it’s usual case that your cousins are always curious to play games and view gallery on your mobile and the hard part is you can’t say “NO”. In fact, someone may sneak your phone without permission and take valuable or private data that you don’t want to share.
Here’s the quick solution for your android device to hide any file without using any third party app. The hidden file will not be view-able on your gallery, multimedia players, office editors, etc. It’s easy and only takes a second to hide your data from anyone until and unless the person knows about this trick.
  • Unlock your device, and open File Manager
  • Click the setting option > Show Hidden files
  • Now go the desired file/folder that you want to hide.
  • Just rename the file with (.) dot before the filename and save it. For example, “.sandy” or “.thequickblog”
  • And the file will be hidden. You can mark/unmark the Show hidden file option whenever you desire.
Hiding the Contents Without Renaming the Folder
  • To do so you can create a file by naming it as “.nomedia” inside the folder that you want to hide. It’s content on the Gallery will be hidden without renaming the folder.
Note: It works on most of the android devices but for Sony Xperia series, this workaround works only if it is a Premium app. In free version you can’t access this feature. You better download a file manager from google play store.
For Samsung devices, the name of default file manager is Files.

TIP 7: HOW TO ADJUST BRIGHTNESS BY SLIDING ACROSS STATUS BAR IN CYANOGENMOD

Ability to adjust brightness of your Android device screen by sliding across status bar is one of the cool feature which CyanogenMod has brought to their latest ROMs. In most of the android devices, brightness can be adjusted using the brightness level bar, but CyanogenMod users can quickly adjust the screen brightness of their CM powered Android device by sliding across the status bar.
Activating “Slide Status Bar to Adjust Brightness” Feature
  • Visit Settings
  • Select Status Bar under personal heading
  • Tap on Brightness control
Adjusting Brightness from Status Bar
Place your finger over the status bar and slide from left to right to increase the brightness and similarly slide for right to left to decrease. You can see the changes in the brightness level of your device in realtime, while you slide your finger across the status bar.

CONCLUSION

I hope these android tips were in anyway helpful to you.
Android is the most customizable phone out there, there are many workarounds which you can perform with your Android device to get most out of it. So for now, I am signing off from this post, promising you guys that I will be back with more other Android tips and guides.

Oracle VM VirtualBox Manager: Add Network Drive / Shared Folder in Windows Server 2012 R2

Share a folder outside the VM in computer's drive and add a network location inside i.e. from Virtual Machine enabling the Guest Addition. This enables access to your shared folder.

In computing, this situation of inadequate softwares/tools/operating systems occurs quite often if you are a tech junkie who loves experimenting numerous tools or operating systems on your single machine. Harddisk partitioning for dual boot operating system is one popular solution to accommodate two

Today, I did Windows Server 2012 setup on my Oracle VM VirtualBox Manager which was an easy task. But right after I completed the setup, I find out that  I was unable to access my computer files and folders from the virtual machine I set up.

So this blog is about my findings on accessing your machine's drive (file and folders) while you are  using an operating system installed inside your virtual machine. This is actually a simple task and it took me less than five minute to configure but at least half an hour to find the solution.

I'm using Oracle VM Virtual Box Version 5.1.8 r111374(QT5.5.1). While I tried to add a network drive for using local partition as a shared drive on my newly installed Windows Server 2012 in my VM following error was encountered:
Oracle VM requires the VirtualBox Guest Addition be enabled in order to add shared folder. The error message also also tells how to use virtual machine inside the virtual machine. Our task now is to install guest addition. To do so:
  • Go to Devices menu
  • Select Insert Guest Additions CD image
Install the Guest Addition for Virtual Box. after installation of Guest Addition, we are now able to add the guest drives to access from virtual machine. Now this is how we add shared drives:
  • Right Click your Virtual Machine
  • Click Settings
  • Click Shared Folders

  • Add a Machine folder
  • Not that in order to access any folder from you virtual machine you first need to change the folder properties and share it. Only the shared folders are accessible.

After you've shared a folder outside the VM in your computer's drive and added a network location from the inside  i.e. from your Virtual Machine enabling the Guest Addition. you can now easily access the shared folder.



This was a simple yet useful tips that I've shared in this blog. On my Next blog I will share how to download files from your web browser (Internet Explorer which is the default browser available) in a Windows Server.

Quantum Computing: Next Generation's Biggest Invention

Quantum Computing: Next Generation's Biggest Invention

The theoretical studies of computation systems which makes the direct use of quantum – mechanical phenomena, such as superposition and entanglement to perform operations on data is called quantum computing. Quantum computers are different from binary digital electronic computers. Binary digital electronic computer uses binary digit 0 and 1 where as quantum computation uses quantum bits which can also be superposition of both 0 and 1. The field of quantum computing was initiated by the work of Paul Benioff and Yuri Manin in 1980. By the change of time many others took a initiative to develop it. 

What is a qubit?

 A qubit just like a classical bit has two possible states | 0 > and (denoted in dirac notation ). But unlike classical bit a qubit can be in more than two possible states. That is, it can be in a superposition of states and . Mathematically, a superposition state looks like,

In the above expression is the probability amplitude for state and β is the probability amplitude for state . and both can be complex numbers. Since and are probabilities amplitudes, they must be normalized. Mathematically,

Qubits can be represented in terms of polarization of a photon where vertical and horizontal polarization are the two states. It can also be represented in terms of spin of an electron. There are number of quantum computing models distinguished by the basic elements in which the computation is decomposed.

Quantum Computing Models

Adiabatic quantum computer based on quantum annealing
Here, the computation gets decomposed into a slow continuous transformation of an initial Hamiltonian (is a operator corresponding to the total energy of the system in quantum mechanics) into a final Hamiltonian whose ground state contain the solution.

One way quantum computer
The computation decomposed into sequence of one quantum bit measurements applied to a highly entangled initial state or cluster state.

Topological quantum computers
The computation decomposed into the brading of anyons in a 2D lattice.

Quantum gate array: The computation decomposed into sequence of few quantum bit quantum gates.
A quantum bit can hold even more information, e.g. up to two bits using superdense coding. Hence, quantum computers will be able to analyze the vast amount of data collected by telescope and seek out earth like planet. The concept of quantum computational models will help to determine how diseases developed. Google itself is using a quantum computer to design software that can distinguish cars from landmarks. 

A quantum may be the smallest measurable finite unit but quantum computing may unlock doors to infinity. It is expected to be the next biggest invention in computing despite the fact that most experts concede that the first quantum computer may be some years off.
