Recursively copy a directory (using cp, tar or rsync)

Original Source: http://snipplr.com/view/26670/

Reformatted for improved readability and personal reference.

How does one make a recursive, identical copy of /source/ into /target/?

I suppose you want to do that for archiving or duplicating something and want to preserve "everything". That includes permissions, ownership, filetypes, timestamps etc.

NAT and FORWARD with Ubuntu’s ufw firewall

UFW

I use Ubuntu’s Uncomplicated firewall because it is available on Ubuntu and it's very simple.

Install UFW

if ufw is not installed by default be sure to install it first.

Instructions on how to fix npm if you've installed Node through Homebrew on Mac OS X or Linuxbrew

OBSOLETE

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.
