Often you need to download and extract archives from the internet, e.g. to install Drupal modules. Therefore you download the archive, extract it and remove the original archive. Using modern[tm] UNIX pipes you can directly pipe it to tar; therefore you don't need to save and remove the archive.

Example:

user@host> wgetar http://ftp.drupal.org/files/projects/views-7.x-3.5.tar.gz

See the result: {{{ user@host> ls -R

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
