C - still no replacement

People who design languages can't resist the temptation of doing clever stuff. The result if that we still are having to deal with C problems that could have been solved years ago. Until this is done, we are stuck with this language.

Real issues with C

Lack of namespaces
Preprocessor is bad
Enums don't have explicit integer type

archlinux install with (almost) full disk encryption, btrfs and RAID

This tutorial is not ready yet.

This tutorial focuses on the disk setup and boot process. You should be familiar with a standard archlinux installation to follow along. However, I also added some general things that the archlinux installation guide fails to adress.

Setup

2 disks of 2TB each

BTRFS and RAID

Basics

RAID stands for "redundant array of inexpensive/independent disks". It is a way of organizing disks.
There are hardware and software RAID implementations, for instance:
- mdadm is a software implementation found in the linux kernel

some CPUs have hardware RAID
