Who develops Linux?

Linus Torvalds (pictured above) started the Linuxproject, and although he has only written 2% of the

code, he has written the most of anyone alone.

The UNIX Philosophy

UNIX-like operating systems have been traditionallywritten by programmers, made for programmers. Thismeans it is easy to programmatically work on data.

1 Write programs which do one thing, and one thing well2 The output of a program should become the input of another

curl http://site/d.img.gz

| zcat

| dd of=/dev/sdb

The Linux Way

Distributions include apackage manager, a programwhich is responsible for:

software installationdependency resolutionsoftware updatessoftware removal

Linux is Ultra Customizable

Because Linux is just a kernel, so many software packages exist torun on top of it. You get the choice of these packages to make thedesktop just how you like it.

Arch Linux Distros

Started in 2002 and there hasn’t been anew version released since

I’m not joking… Arch Linux is a rollingrelease. Updating your system throughpacman brings you to the latest

Comes with basically nothing out of thebox, it’s up to you to install the softwareyou want to use

Software packages are usually bleedingedge

Very helpful and kind community
