Writing Message in Binary Form
A fun way of learning binaries

Ever wondered how to write messages in binary form? Yet, you think it’s hard to remember all 26 letters both lowercase and uppercase in binary form? Ever stumbled upon someone who can read binary form in ease?

I have this curiosity when I was in secondary school or junior high school. Yet, every time I saw the bunch of 0s and 1s, I always thought “Forget it, I can just refer it online next time”. This is not an efficient way. Later on, I figured something out after an observation.

There is a pattern to them, both Uppercase letters and Lowercase letters. Be reminded that this is based on ASCII in particular.

The binary form that I will write here will be in a byte size (8 bits).

For digits, 0 to 9, they all start with 0011 followed by 4 bits:

  • 0011 0000 is 0
  • 0011 0001 is 1
  • 0011 0010 is 2
  • 0011 0011 is 3
  • 0011 0100 is 4
  • 0011 0101 is 5
  • 0011 0110 is 6
  • 0011 0111 is 7
  • 0011 1000 is 8
  • 0011 1001 is 9

For Uppercase alphabetic characters, they start with 0100 for A up to O, 0101 for P up to Z.

  • 0100 0001 is A
  • 0100 0010 is B
  • 0100 0011 is C
  • 0100 0100 is D
  • 0100 0101 is E
  • 0100 0110 is F
  • 0100 0111 is G
  • 0100 1000 is H
  • 0100 1001 is I
  • 0100 1010 is J
  • 0100 1011 is K
  • 0100 1100 is L
  • 0100 1101 is M
  • 0100 1110 is N
  • 0100 1111 is O
  • 0101 0000 is P
  • 0101 0001 is Q
  • 0101 0010 is R
  • 0101 0011 is S
  • 0101 0100 is T
  • 0101 0101 is U
  • 0101 0110 is V
  • 0101 0111 is W
  • 0101 1000 is X
  • 0101 1001 is Y
  • 0101 1010 is Z

For Lowercase alphabetic characters, they start with 0110 for a up to o, 0111 for p up to z.

  • 0110 0001 is a
  • 0110 0010 is b
  • 0110 0011 is c
  • 0110 0100 is d
  • 0110 0101 is e
  • 0110 0110 is f
  • 0110 0111 is g
  • 0110 1000 is h
  • 0110 1001 is i
  • 0110 1010 is j
  • 0110 1011 is k
  • 0110 1100 is l
  • 0110 1101 is m
  • 0110 1110 is n
  • 0110 1111 is o
  • 0111 0000 is p
  • 0111 0001 is q
  • 0111 0010 is r
  • 0111 0011 is s
  • 0111 0100 is t
  • 0111 0101 is u
  • 0111 0110 is v
  • 0111 0111 is w
  • 0111 1000 is x
  • 0111 1001 is y
  • 0111 1010 is z

Now you can write somewhat cryptic message to whoever you want.

01010100 01101000 01100001 01101110 01101011 01111001 01101111 01110101 !

Web developers are no strangers to APIs — especially HTTP methods like GET and POST. When it comes to designing APIs, backend engineers or API engineers are familiar with them as well. That means REST is a term that is familiar. It is said that REST is an architecture and not a standard. It was developed alongside HTTP and is most commonly used over HTTP. HTTP is a standard, whereas REST is an architecture. REST is an architectural style that provides constraints tha

The Hypertext Transfer Protocol, more commonly known as HTTP, is said to be a standard. It is used to communicate between clients and servers. How it works is through the request-response protocol between a client and server. A quick example of how it works: Imagine your browser (client) sends an HTTP request to the server (for whichever site you are trying to access). Then the server returns a response to the client. This response conta

4 Ways To Perform Python String Formatting 4 Ways To Perform Python String Formatting Generate the strings that you like in Python Photo by Artturi Jalli on  Unsplash String formatting can be pretty fundamental and simple, but what really triggered me was what was the best way to do the formatting while writing the code for specific situations. And that curiosity kinda let me down the rabbit hole. On a side note, I actually wrote other Python related articles before like Python Number Formatting Binary Type which probably needs me to write another one more on just Python 3. If you are also keen, I wrote this piece on writing messages in binary just for fun. Other than that, I did write mostly on Java and a few on JavaScrip
