Ubuntu Server Installation Notes for Partitioning a 2 Disk System to Boot From a RAID 1 Device

This note explains how to install Ubuntu Linux Server on a computer with two hard disks, with RAID 1, so it boots from the array. The entire installation, including partitioning and RAID administration, is done through the installer, and doesn't really require any access to the commands. (This is a work in progress, and we don't have screenshots yet.)

(Just to be fair, I think the SSL cert business is a scam, so there.)

Installing XCP-XAPI on Ubuntu Server 12.04 LTS

Supermicro Server Keeps Booting after 5 Minutes

I got this snazzy used Supermicro server, and after I set it up to run SSH, and I started to configure it, it started to reboot every five minutes.

Parity in Computer Data, What is It?

Parity, in computer data, is a bit that's set or unset so the total number of bits is either even or odd. It's an extra bit, and it's added as a check on the data.
