1. Initialization

Declaring an empty vector and then pushing values

// creates an empty vector
std::vector<int> vec;
// push values into vector
vec.push_back(10);
vec.push_back(20);
vec.push_back(30);

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

Modules

Here'e an example of how to register a nick on Freenode IRC. It's a little tricky, but if you follow some simple steps, you'll get through it okay. All you need to do is connect to the Freenode IRC network and have a little talk with NickServ.

The first and most confusing questions can be combined:

How do I know if my nick is already registered to someone else?
How do I talk to NickServ?

Start by connecting your client to irc.freenode.net and joining any chat.

Next, type this command in the chat window:

	OK, Let's begin. Hello, Everybody.
	My name is Narihiro Nakamura.
	Today, I'm talking about "Parallel worlds of CRuby's GC".

	I'm very happy now, because I'm meeting attendee in rubyconf.
	And, one of my dreams is to talk in rubyconf.
	So, I'm very happy and exciting.

	Today is my first presentation in English.
	My English is not good.

	module TwosComplement
	def self.encode(n)
	if n < 0
	binary = (n + 1).abs.to_s(2).chars.map { \|c\| c == "0" }
	binary.unshift(true) unless binary.first == true
	else
	binary = n.to_s(2).chars.map { \|c\| c == "1" }
	binary.unshift(false) unless binary.first == false
	end

	module TwosComplement
	def self.encode(n)
	if n < 0
	binary = (n + 1).abs.to_s(2).chars.map { \|c\| c == "0" }
	binary.unshift(true) unless binary.first == true
	else
	binary = n.to_s(2).chars.map { \|c\| c == "1" }
	binary.unshift(false) unless binary.first == false
	end

	// This program is an example of how to run a command such as
	// ps aux \| grep root \| grep sbin
	// using C and Unix.

	#include <stdlib.h>
	#include <unistd.h>

	int pid;
	int pipe1[2];
	int pipe2[2];

	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

	// Use Gists to store code you would like to remember later on
	console.log(window); // log the "window" object to the console
