Linkage

Identifiers for variables and constants declared at file scope have external linkage (i.e. visible in other translation units).

Both are initialized to zero for variables and NULL for pointers by default, and exist for all the lifetime of the program.

A variable declared inside a function that keeps its value between invocations (as if it were global), and so is initialized only once.
Function or variable is only visible (callable) within the same *.c file it was defined into (limited scope => optimal performance).

From this [youtube tutorial][1]:

Inheritance (is-a relationship): design objects around what they are.
Composition (has-a relationship): design objects around what they do (i.e. behavior).

Favor composition over inheritance.

Drawback: a derived class inherits all functionalities, even those it doesn't need.

git fetch origin master
git rebase -X theirs

theirs means ours in the case of a rebase (inverse of git merge).

Means the end of command options, after which only positional parameters are accepted.

#include <iostream>

using namespace std;

$ nasm -f elf -o script.o script.asm
$ ld -m elf_i386 -o script script.o

-elf is used in nasm to produce a 32 bits object file (otherwise it outputs a binary file by default which is difficult to link).

	# 1000 samples from standard normal dist
	x = seq(1, 1000)
	y = rnorm(1000)
	y_normalized = (y - min(y)) / (max(y) - min(y))

	# split in half and with different color
	median = median(y_normalized)
	print(median)
	plot(x, y_normalized, pch=21, bg=ifelse(y_normalized > median, 'red', 'green'))
