How to Share Files Between Mobile Phones and Computers

Your files are spread across phones, tablets and computers. Find the right apps to transfer files between Windows PCs, Macs, iPhone, iPad and Android devices. 

Your digital photos, documents, music, and other files are spread across a range of devices from your mobile phones to tablets and your computers.For instance, how you do you transfer a file from your Android mobile phone to your iPad? Or how will you send a snippet of text copied on your Windows computer to your iPhone without emailing yourself? What is the quickest way to move multiple files from one Android tablet to anotherShare Files Between Android, iOS, Mac & Windows

The following how-to guide discusses apps, both web-based and mobile apps, that will help you transfer files, photos, web pages and everything else between your desktop computers and mobile devices easily without needing a USB cable.

The popular and most obvious solution for sharing files across devices is email. Send a file to yourself from one device and then download that email attachment on the other device. For bigger files, you can upload them to Dropbox, OneDrive or Google Drive from one device and download on your other device(s). If you are on a Wi-Fi network, prefer Dropbox since it will download the file over LAN instead of the cloud and thus the transfer would happen at a much faster rate.

If you wish to transfer text snippets, web page URLs or even clipboard content from one device to another, Google Keep is a recommended option. You can copy-paste text inside Keep and it instantly becomes available on your Android device. iOS and Mac users can install Scribe or BeamApp to effortlessly copy web page links and text notes from the Mac to your iPhone or iPad.

Like Keep, Push Bullet is another very handy app for sending web pages, map directions, text notes and even small files from your computer to phone, phone to phone or between computers. Push Bullet supports push notifications. It is available for iPhone, Android and desktop computers (as a Chrome add-on) while the iPad version will be available soon.

AirDroid is probably the only app you’ll ever need for moving files in and out of your Android phone and tablet wirelessly. Launch the AirDroid app on your Android, open web.airdroid.com on your desktop browser and scan the QR code to make the connection. Mac can install Droid NAS to access your Android phone’s folders and the SD card inside Finder as a Bonjour computer.

Unlike Android, Apple does not provide access to the iOS file system except for the media gallery. You can use Documents or Good Reader to transfer documents, photos and other files from the computer to your iPad and iPhone (or vice versa) over the local Wi-Fi network. These apps can be mounted as a network drive on your computer and they have a built-in browser to help you download and save web files that won’t download in the Safari browser.

Computer maker Lenovo recently introduced the ShareIt app for sharing files and everything else between your Android, iOS and Windows PCs. The app creates an ad-hoc network for sending files from one device to another and requires no Wi-Fi network, Bluetooth or data connection. The interface is beautiful, uncomplicated and all the recipient has to do is connect their device to the Wi-Fi network created by the app on the sender’s device for transferring files.

The popular JustBeamIt service offers an Android App to help you transfer files from your phone to the computer. Just select a file on the phone inside the JustBeamIt app and it will generate a unique URL. Open this URL on your desktop and the transfer would happen directly between your phone and computer over a P2P connection.

SuperBeam is another useful app for transferring files between Android devices. Select one or more files inside any file manager app and choose SuperBeam from the system-wide sharing menu. It will generate a QR code that you can scan with SuperBeam on your other device and the file transfer will happen automatically. If the two Android devices are not connected to the same Wi-Fi network, SuperBeam will transfer files using Wi-Fi Direct or NFC. The pro version also lets you send files from Android to your Mac, Windows or Linux computer (requires Java).

Any Send also makes it very easy to transfer files or even entire folders between devices over Wi-Fi. It’s more like a cross-platform version of AirDrop. You can copy a file or folder to the clipboard and paste it on your other devices visible inside Any Send. You can share files between Mac and PCs or between your Android phone and desktop computers.

Apple’s AirDrop is the perfect option for transferring files between your Macbook and iMac or between your iPhone and iPad. The upcoming version of AirDrop will also let you send files from Mac to iOS devices but until that happens, you can the free InstaShare app. All you have to do is drag the file from your computer to the target device. It works over Wi-Fi or Bluetooth and, unlike AirDrop, supports older iPhones and Macs as well.

If you need to transfer files between your Android phone and iPhone or iPad, Send Anywhere is a good option. You can send files of any size over peer-to-peer (when the two devices are on the same network) else it uses the cellular connection. All you have to do is pair the two devices by entering a 6-digit key and begin the transfer. They have a web-app as well allowing you to send (or receive) files from the desktop to your iOS or Android device.

Finally, you’ve BitTorrent Sync for automatically syncing folders between Windows, Mac, iPhone, iPad, Windows Phone and Android devices. The transfers do not involve the cloud – you put a file in the folder of one device and it magically appears on all your other devices.

Choose the Right App for Sharing Files

ShareItThe devices are running different operating systems and therefore there’s no starard method that will allow you to easily copy files from one device to another.

How to increase speed of online video

This is normal stuff to play an online video much faster than the normal speed or in slow internet connection. Maximum online video broadcasting channel uses flash player, which is slower than the Html5 video broadcasting. Either, you can use html5 media player or use your own installed media player in PC. Let’s do this stuff using VLC media player, which is more popular media player.

There are same steps to increase speed as:

    1.       Open VLC media player

    2.       Open media->Stream

    3.       Open Network

    4.       Add your online video link(Example of youtube  video link is: http://www.youtube.com/watch?v=bDHFDK3x4Uo)

    5.       Click on Play. Take stream output as stream.

    6.       Now go to Playback->speed->faster. This will boost your speed of arrival frames. 

    7.       Increase speed up to 4.0x.

 you can also play a youtube video on html5:

    1.       Open http://youtube.com/html5

    2.       Do request for it default player.

    3.       Open http://youtube.com , now it will open as html5 player.

How to schedule and limit your google forms

How to schedule and limit your google forms

Google Forms impose no limits. Any poll or survey created inside Google Forms has no expiration date and it can collect unlimited number of responses until the form owner decides to manually close* the form. But you can schedule these from and close it by trigger. Suppose anyone wants to set their form before 5 days and think after 5 days it will open for general user. For this situation you need to apply trigger on script editor by using some lines of Google Script.

Setting Expiration date and time of form:

Google script editor give flexibilty to set your expiration date and limiting your forms as following.

1.Go to google drive and click on existing or create new form

2.Inside editor click on Tools->Script editor.

3.Click on Form

4.Set DATE_OPEN   =  "2014-01-04 06:00". On this time your form will be visible.

5.Set DATE_CLOSE =  "2014-03-2 11:59". After this dste snd time your form will be invisible.

6.Set MAX_RESPONE   =  "200". This will set your maximum number of response.

7.(CNTL+S) save your script.

 Google Script for Setting expiration and Limiting response

DATE_OPEN   =  "2014-01-04 06:00"

DATE_CLOSE =  "2014-03-2 11:59"

/* Initialize the form, setup time based triggers */

function Initialize() {

 

  deleteTriggers_();

 

  if (DATE_OPEN !== "") {

    .create();

  }

 

  if (MAX_RESPONE !== "") {

    ScriptApp.newTrigger("checkLimit")

    .forForm(FormApp.getActiveForm())

    .onFormSubmit()

    .create();

  }

}

/* Send a mail to the form owner when the form status changes */

}

/* Close the Google Form, Stop Accepting Reponses */

function closeForm() { 

  var form = FormApp.getActiveForm();

  form.setAcceptingResponses(false);

  informUser_("Your Google Form is no longer accepting responses");

}

/* If Total # of Form Responses >= Limit, Close Form */

function checkLimit() {

  if (FormApp.getActiveForm().getResponses().length >= MAX_RESPONE ) {

    closeForm();

  } 

}

/* Parse the Date for creating Time-Based Triggers */

function parseDate_(d) {

  return new Date(d.substr(0,4), d.substr(5,2)-1,

                  d.substr(8,2), d.substr(11,2), d.substr(14,2));

Generally programmers of windows apps faces problem while installing sdk 8.0, one of the major problem I would like to discuss with you. Most of the time we encounter following problem “Windows Phone 8 SDK: A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file in other word we generally see  windows Software Development Kit Tools for Windows Store . A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file”.

There are two solution of this problem:

A)    By changing local time.  Details are as follows:

Set the computer's date to 16 July 2013 or earlier, run installation, then update the date

to the present

     1.      Right click date and time in lower right corner of screen.

2.      Select Adjust Date/Time

3.      Click the Change Date and Time button.

4.      Select 16 July 2013 on the calendar.

5.      Click OK.

6.      Click OK.

7.      Run the installer again.

When installation is complete, use steps 1 through 6 to set the date to the current one.

B)    By downloading small (.msi) file generally 344KB to fix this issue.

1) Uninstall the partially installed Windows Phone SDK 8.0 if it currently installed on your computer.

2) Download the .msi and .cab files from the following 4 locations and save them to the same folder on your computer:

http://go.microsoft.com/fwlink/?LinkId=257143

http://go.microsoft.com/fwlink/?LinkId=257144

http://go.microsoft.com/fwlink/?LinkId=257145

http://go.microsoft.com/fwlink/?LinkId=257146

3) Go to the folder where you have saved downloaded file and run this file named “Win8SharedSDKTools.msi”.

vigenere cipher

Description

Vigenere  cipher is used for encrypting alphabetic text. In a Caesar cipher, each letter of the alphabet is shifted along some number of places; for example, in a Caesar cipher of shift 3, A would become D, Bwould become E, Y would become B and so on. The Vigenère cipher consists of several Caesar ciphers in sequence with different shift values.

To encrypt, a table of alphabets can be used, termed as Vigenère square, or Vigenère table. It consists of the alphabet written out 26 times in different rows, each alphabet shifted cyclically to the left compared to the previous alphabet, corresponding to the 26 possible Caesar ciphers. At different points in the encryption process, the cipher uses a different alphabet from one of the rows. The alphabet used at each point depends on a repeating key.

For example, suppose that the plaintext to be encrypted is:

cryptograph

The person sending the message chooses a keyword and repeats it until it matches the length of the plaintext, for example, the keyword "vein":

veinveinvei

Each row starts with a key letter. The remainder of the row holds the letters A to Z (in shifted order). Although there are 26 key rows shown, you will only use as many keys (different alphabets) as there are unique letters in the key string, here just 4 keys, {v,e,i,n}. For successive letters of the message, we are going to take successive letters of the key string, and encipher each message letter using its corresponding key row. Choose the next letter of the key, go along that row to find the column heading that matches the message character; the letter at the intersection of row and column,  is the enciphered letter.

For example, the first letter of the plaintext, c, is paired with v, the first letter of the key. So use row v and column c of the Vigenère square, namely v. Similarly, for the second letter of the plaintext, the second letter of the key is used; the letter at row r and column e is v. The rest of the plaintext is enciphered in a similar fashion:

Plaintext:	cryptograph
Key:	veinveinvei
Ciphertext:	Xvgcojoevtb

Decryption is performed by going to the row in the table corresponding to the key, finding the position of the ciphertext letter in this row, and then using the column's label as the plaintext. For example, in row v (from vein), the ciphertext v appears in column c, which is the first plaintext letter. Next we go to row e (from vein), locate the ciphertext v which is found in column r, thus r is the second plaintext letter.

Find rank of matrices using SR modulus Method

In engineering mathematics it is not easy to find rank of matrices. SR Modulus method give us flexibility and  easy way to find rank of matrices. This method is working under the project “LOCO POCO SOCO”, developing by S.K. Chakravarti since 2009.

SR Modulus method:

If a matrix A= , then find the rank of matrix A.

B=A%(Prime Number P)

Let prime number be 2. Then matrix B will be

B=

Apply elementary row and column elimination. Try to do (n-1) elements of  any one row or column of matrix B to be 0.

If Maximum elements are in the form of 2n,3n,5n,7n…..,  then take prime number P as upper prime.

Apply these Modulus and elimination till every elements gets  {-1,0,1}.

Rank(A)=Number of none zero rows or columns of matrix B.

 Download .pdf file: Click Here

Example:

Given that a 3x3 matrix A=. Find the Rank of matrix A.

Solution:

Applying modulus 2, then B=A%2.

B=

Number of none zero rows or column = 2

Hence, Rank(A)=2    ANS.

If you have any problem regard this you can contact me via comments or email.
