SSH keypair setup for GitHub (or GitHub/GitLab/BitBucket, etc, etc)

Create a repo.

Make sure there is at least one file in it (even just the README.md)

Generate a SSH key pair (private/public):

ssh-keygen -t rsa -C "your_email@example.com"

Example inputs:

Variable	Value
key	`the shared secret key here`
message	`the message to hash here`

Reference outputs for example inputs above:

| Type | Hash |

Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096

Sort object properties by value (values are text)

I have following object:

var cities={10:'Tashkent', 14:'Karakalpakiya', 16:'Andijan'};

I want sort it by city names, so after sort it should be:

var cities={16:'Andijan', 14:'Karakalpakiya', 10:'Tashkent'};

But I can't sort object properties, instead can convert object into array, then sort items.

	function birthday(s, d, m) {
	let result = 0;
	for(let i = 0; i < s.length - (m - 1); i++) {
	if (s.slice(i, i + m).reduce((r, v) => r + v, 0) === d) {
	result++;
	}
	}
	return result;
	}

	Serial Keys:

	GDB commands by function - simple guide
	---------------------------------------
	More important commands have a (*) by them.

	Startup
	% gdb -help print startup help, show switches
	*% gdb object normal debug
	*% gdb object core core debug (must specify core file)
	%% gdb object pid attach to running process
	% gdb use file command to load object
