How to Add Label and Related Post to Blogger

Label is a function in Blogger that let you categorize your post. You might want to label your post as "Places of Interest" when your post is about your experience visiting other countries. When your reader click on the Label, they will be redirected to specific posts under the same Label. Another feature that would be useful is the Related Post feature. By using this feature, you somehow persuade your readers to keep on reading your blog and build the engagement in the future. Other advantage of using the Related Post feature is to let the past stories accessible to new readers. The easiest way to do this is by adding related post widget using site like LinkWithin or nRelate. In this post we will show how you can use LinkWithin to add Related Post to your blog.

Adding Label

Step 1
Log in to your Blogger account. Click the "Posts" link on the left of your blog edit page, check the box on which post you would like to label  then click on the "Label Selected Post"

Step 2
When the "Label Selected Post" is clicked, you can continue with the naming of your New Label. Your label will be shown next to the post title (as in Example of Label) below:

Step 3 
You can display the Label using "Add a Gadget" in your layout page.

Step 4
Click the preview button and your label should look something like this:

Adding Related Post

Step 1
Go to http://www.linkwithin.com/learn then fill in your email, the link to your blog, the platform (i.e. Blogger, WordPress (self-hosted), TypePad) that you are using (in this case Blogger), and width. The width is the option you can put how many stories or related post you like your reader to see.

Step 2
Click the Get Widget button and follow the steps shown by the page. The steps are as below

What is Hamming Code? How It Can Detect and Correct Error?

Transmission error can be caused by noisy communication channel such as scratches on a CD, static on a cell phone, or atmospheric interference. Therefore, there is a need to detect and recover the original message from the corrupted data. One method to detect and correct error is by using Hamming code that was invented by Richard Hamming in 1950. It make use the concept of additional bit called parity. In this page you will learn how to get the formula for 4, 8 and 16 bit Hamming data transmission. Based on the formula, you will see how Hamming can detect and correct error. Though only 4, 8, and 16 bit Hamming is shown, the same concept applies to others. 

• 4-bit Data Transmission using Hamming 
• 8-bit Data Transmission using Hamming 
• 16-bit Data Transmission using Hamming

4-bit Data Transmission using Hamming

The number of parity bit depends on the number of data to be transmitted. The parity bit is inserted at each 2^n location which will make a 4-bit data (i.e. D3,D2,D1,D0) transmission will need 3 parity bit (i.e. at P1, P2, P4)

4-bit data with 3 parity bit produce 7 bit number

This will total up the data transmission to 7 bit. Every 3 bit parity is used to detect group of bit. Every parity bit is for themselves and has bit ‘1’ on certain position bit.

   C1 = xx1 (001,011,101,111) = {1,3,5,7}
   C2 = x1x (010,011,110,111) = {2,3,6,7}

   C4 = 1xx (100,101,110,111) = {4,5,6,7}

Omitting the 2^n number, therefore:

   P1 = parity for bit {3,5,7}
   P2 = parity for bit {3,6,7}
   P4 = parity for bit {5,6,7}

Example: Given a 4-bit number "1100" and assume even parity bit, show how Hamming Code is able to detect and correct the data if the receiver received "1000".

Answer: Arrange the "1100" as below

The question assume even parity, therefore  all the the three parity bit and the answer (all together 4 bit) should be even. Another method is by using XOR to the three parity bit.

   P1 = parity for bit {3,5,7} = parity for bit {D3,D2,D0}= 1 XOR 1 XOR 0 = 0
   P2 = parity for bit {3,6,7}= parity for bit {D3,D1,D0}= 1 XOR 0 XOR 0 = 1
   P4 = parity for bit {5,6,7}= parity for bit {D2,D1,D0}= 1 XOR 0 XOR 0 = 1

Put the answer for P1, P2, P4 at their respected location as below:

To check error, execute checking code

   C1= XOR {1,3,5,7} = XOR{P1,D3,D2,D0}= 0 XOR 1 XOR 1 XOR 0 = 0
   C2= XOR {2,3,6,7} = XOR{P2,D3,D1,D0}= 1 XOR 1 XOR 0 XOR 0 = 0
   C4= XOR {4,5,6,7} = XOR{P4,D2,D1,D0}= 1 XOR 1 XOR 0 XOR 0 = 0

C4 C2 C1=000 therefore no error.

Now try to check what happen when data received is "1000"

   C1= XOR {1,3,5,7} = XOR{P1,D3,D2,D0}= 0 XOR 1 XOR 0 XOR 0 = 1
   C2= XOR {2,3,6,7} = XOR{P2,D3,D1,D0}= 1 XOR 1 XOR 0 XOR 0 = 0
   C4= XOR {4,5,6,7} = XOR{P4,D2,D1,D0}= 1 XOR 0 XOR 0 XOR 0 = 1

C4 C2 C1 = 101 which detect the error at location number 5. 

 8-bit Data Transmission using Hamming

The number of parity bit depends on the number of data to be transmitted. The parity bit is inserted at each 2^n location which will make an 8-bit data (i.e. D7,D6....,D1,D0) transmission will need 4 parity bit (i.e. at P1, P2, P4, P8)

8-bit data with 4 parity bit produce 12 bit number

This will total up the data transmission to 12 bit. Every 4 bit parity is used to detect group of bit. Every parity bit is for themselves and has bit ‘1’ on certain position bit.

   C1 = xxx1 (0001,0011,0101,0111, 1001, 1011, 1101, 1111) = {1,3,5,7,9,11,13,15}
   C2 = xx1x (0010,0011,0110,0111,1010,1011,1110,1111) = {2,3,6,7,10,11,14,15}

   C4 = x1xx (0100,0101,0110,0111,1100,1101,1110,1111) = {4,5,6,7,12,13,14,15}
   C8 = 1xxx (1000,1001,1010,1011,1100,1101,1110,1111) = {8,9,10,11,12,13,14,15}

Note that the number above 12 will be removed (i.e. strike-through).

Omitting the 2^n number, therefore:

   P1 = parity for bit {3,5,7,9,11}
   P2 = parity for bit {3,6,7,10,11}

   P4 = parity for bit {5,6,7,12}
   P8 = parity for bit {9,10,11,12}

Example: Given an 8-bit number "11001011" and assume even parity bit, show how Hamming Code is able to detect and correct the data if the receiver received "1001011".

Answer: Arrange the "11001011" as below

The question assume even parity, therefore all the the four parity bit and the answer (all together 5 bit) should be even. Another method is by using XOR to the four parity bit.

   P1 = parity for bit {3,5,7,9,11} = parity for bit {D7,D6,D4,D3,D1} = XOR(1,1,0,1,1) = 0
   P2 = parity for bit {3,6,7,10,11} = parity for bit {D7,D5,D4,D2,D1} = XOR(1,0,0,0,1) = 0

   P4 = parity for bit {5,6,7,12}= parity for bit {D6,D5,D4,D0} = XOR(1,0,0,1) = 0
   P8 = parity for bit {9,10,11,12}= parity for bit {D3,D2,D1,D0} = XOR(1,0,1,1) = 1

Put the answer for P1, P2, P4, P8 at their respected location as below:

To check error, execute checking code
   C1 = XOR{1,3,5,7,9,11} = XOR{P1,D7,D6,D4,D3,D1} = XOR(0,1,1,0,1,1) = 0
   C2 = XOR{2,3,6,7,10,11} = XOR{P2,D7,D5,D4,D2,D1} = XOR(0,1,0,0,0,1) = 0

   C4 = XOR{4,5,6,7,12} = XOR{P4,D6,D5,D4,D0} = XOR(0,1,0,0,1) = 0
   C8 = XOR{8,9,10,11,12} = XOR{P8,D3,D2,D1,D0} = XOR(1,1,0,1,1) = 0

C8 C4 C2 C1=0000 therefore no error.

Now try to check what happen when data received is "1001011"

   C1 = XOR{1,3,5,7,9,11} = XOR{P1,D7,D6,D4,D3,D1} = XOR(0,1,0,0,1,1) = 1
   C2 = XOR{2,3,6,7,10,11} = XOR{P2,D7,D5,D4,D2,D1} = XOR(0,1,0,0,0,1) = 0

   C4 = XOR{4,5,6,7,12} = XOR{P4,D6,D5,D4,D0} = XOR(0,0,0,0,1) = 1
   C8 = XOR{8,9,10,11,12} = XOR{P8,D3,D2,D1,D0} = XOR(1,1,0,1,1) = 0

C8 C4 C2 C1 = 0101 which detect the error at location number 5. 

 16-bit Data Transmission using Hamming

The number of parity bit depends on the number of data to be transmitted. The parity bit is inserted at each 2^n location which will make a 16-bit data (i.e. D15,D6....,D1,D0) transmission will need 5 parity bit (i.e. at P1, P2, P4, P8,P15)

16-bit data with 5 parity bit produce 21 bit number

This will total up the data transmission to 21 bit. Every 5 bit parity is used to detect group of bit. Every parity bit is for themselves and has bit ‘1’ on certain position bit.

   C1 = xxxx1 

         = (00001,00011,00101,00111,01001,01011,01101,01111,

             10001,10011,10101,10111,11001,11011,11101, 11111)

         = {1,3,5,7,9,11,13,15, 17,19,21,23,25,27,29,31}

   C2 = xxx1x

         = (00010,00011,00110,00111,01010,01011,01110, 01111,

             10010,10011,10110,10111,11010,11011,11110, 11111)

         = {2,3,6,7,10,11,14,15, 18,19,22,23,26,27,30,31}

   C4 = xx1xx
         = (00100,00101,00110,00111,01100,01101,01110, 01111,
             10100,10101,10110,10111,11100,11101,11110, 11111)
         = {4,5,6,7,12,13,14,15, 20,21,22,23,28,29,30,31}

   C8 = x1xxx

         = (01000,01001,01010,01011,01100,01101,01110, 01111,

              11000,11001,11010,11011,11100,11101,11110, 11111)

         = {8,9,10,11,12,13,14,15, 24,25,26,27,28,29,30,31}
   C16= 1xxxx
          = (10000,10001,10010,10011,10100,10101,10110, 10111,

               11000,11001,11010,11011,11100,11101,11110, 11111)

          = {16,17,18,19,20,21,22,23, 24,25,26,27,28,29,30,31}

Note that the number above 21 will be removed (i.e. strike-through).

Omitting the 2^n number, therefore:

   P1 = parity for bit {3,5,7,9,11,13,15, 17,19,21}

   P2 = parity for bit {3,6,7,10,11,14,15, 18,19}
   P4 = parity for bit {5,6,7,12,13,14,15, 20,21}
   P8 = parity for bit {9,10,11,12,13,14,15}

   P16 = parity for bit {17,18,19,20,21}

Example: Given a 16-bit number "1110 0100 1011 0010" and assume even parity bit, show how Hamming Code is able to detect and correct the data if the receiver received "1110 0100 1011 1010".

Answer: Arrange the "1110 0100 1011 0010" as below

The question assume even parity, therefore all the the five parity bit and the answer (all together  6 bit) should be even. Another method is by using XOR to the five parity bit.

   P1 = parity for bit {3,5,7,9,11,13,15, 17,19,21} = XOR(1,1,0,0,0,1,1,1,0,0) = 1

   P2 = parity for bit {3,6,7,10,11,14,15, 18,19} = XOR(1,1,0,1,0,0,1,1,0) = 1

   P4 = parity for bit {5,6,7,12,13,14,15, 20,21} = XOR(1,1,0,0,1,0,1,1,0) = 1

   P8 = parity for bit {9,10,11,12,13,14,15} = XOR(0,1,0,0,1,0,1) = 1

   P16 = parity for bit {17,18,19,20,21} = XOR(1,0,0,1,0) = 0

Put the answer for P1, P2, P4, P8, P16 at their respected location as below:

To check error, execute checking code

   C1 = XOR{1,3,5,7,9,11,13,15, 17,19,21} = XOR(1,1,1,0,0,0,1,1,1,0,0) = 0

   C2 = XOR{2,3,6,7,10,11,14,15, 18,19} = XOR(1,1,1,0,1,0,0,1,1,0) = 0
   C4 = XOR{4,5,6,7,12,13,14,15, 20,21} = XOR(1,1,1,0,0,1,0,1,1,0) = 0
   C8 = XOR{8,9,10,11,12,13,14,15} = XOR(1,0,1,0,0,1,0,1) = 0

   C16 = XOR{16,17,18,19,20,21} = XOR(0,1,0,0,1,0) = 0

C16 C8 C4 C2 C1=00000 therefore no error.

Now try to check what happen when data received is "1110 0100 1011 1010"

   C1 = XOR{1,3,5,7,9,11,13,15, 17,19,21} = XOR(1,1,1,0,0,0,1,1,1,0,0) = 0
