How to use Github repository in SSH mode?

It is preferred that you use SSH to check in code. You will need an SSH key associated with your GitHub account to do this. You can follow the guide created by GitHub, or the steps below.

The following steps are for MacOS. Follow the guide linked above for other operating systems.
  1. Generate an SSH private-public key pair. Open a terminal on your machine and enter
    • ssh-keygen -t rsa
  2. You will be asked where to save the key. The default (~/.ssh/id_rsa) will suffice.
  3. You will be asked for a secure passphrase. If you enter one, you will be asked for this phrase every time you commit changes. Be sure to remember it.
  4. Add the newly generated private key to your SSH agent. Use the following command.
    • ssh-add -K ~/.ssh/id_rsa
  5. Add the newly generated public key (~/.ssh/id_rsa.pub) to GitHub. Go to your account settings and select "SSH and GPG keys". Press "New SSH key".
  6. Give your key a meaningful title (i.e. your computer's name or "Work Laptop")
  7. Copy the public key. The easiest way to do this is with the following command. Alternatively you may open ~/.ssh/id_rsa.pub with your favourite text editor and copy it.
    • pbcopy < ~/.ssh/id_rsa.pub
  8. Paste the key into the "Key" box. Press "Add SSH key".

Unlock protected blocks in Siemens SIMATIC Step 7

Recently I'd been called by Hindalco's Fabrication Plant division to unlock the protected blocks in Siemens SIMATIC Step 7. They were in need to unlock those blocks since an year because of 1 million Rupees of loss per month. They want to re-program those blocks but it was locked by the man who'd done the setup. From the people working in that department, I came to know that they were trying to call that man (someone from Italy) right here but he's not coming. Actually, what he'd done was that he'd locked some of the blocks and deleted the source file. And Siemens didn't provide any feature to unlock. Department people also told me that even the people working in Siemens don't know how to do it. Being a software engineer I know that any thing can be reverse engineered. So I took up the challenge. How did I unlocked the blocks? The first thing I'd done was searched about this software at Google and read about what is this software all about. Aft...

JS: The complete code example of Crypto.js (DES)

For one of the project I was trying to use crypto.js but I found that the Quick-start Guide have some deficiency in terms of library usage. So I am writing it here as a useful note for memory recap. <script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/tripledes.js"></script> <script> var encrypted = CryptoJS.DES.encrypt("The secret message", "secret_key"); var e_msg = encrypted.toString(); console.log(e_msg); var decrypted = CryptoJS.DES.decrypt(e_msg, "secret_key"); var d_msg = decrypted.toString(CryptoJS.enc.Utf8); console.log(d_msg); </script>

Encode or decode date in 3 characters

I have developed a new way to encode/decode dates within 3 characters by using base-36 format. What is a base 36 format? Base 36 or hexatridecimal is a positional numeral system using 36 as the radix. The choice of 36 is convenient in that the digits can be represented using the Arabic numerals 0-9 and the Latin letters A-Z. In simple language, base-36 format refers to series of 0-9 followed by A-Z characters, i.e., 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ; where each character refers to the position index in series. The concept can also be represents as shown in the below table Series Character Series Character Series Character Series Character 0 0 10 A 20 K 30 U 1 1 11 B 21 L 31 V 2 2 12 C 22 M 32 W 3 3 13 D 23 N 33 X 4 4 14 E 24 O 34 Y 5 5 15 F 25 P ...
