Instructions for installing a very clean Debian GNU/Linux system that boots from RAID 1, and has RAID 1 or RAID 5 root and data filesystems.

I hope to turn this into a general easy to follow guide to setting up RAID-5 and LVM on a modern Linux system. However, for now it's basically a collection of my notes as I experimented on my own systems. Please note that my own experimentation was based on the RAID and LVM implementations under Fedora Core 3 & 4, as wel as Red Hat Enterprise Linux 4, all of which are based on the 2.6 series of kernels.

This is an attempt to collect everything needed to know to get LVM up and running. The entire process of getting, compiling, installing, and setting up LVM will be covered. Pointers to LVM configurations that have been tested with will also be included. This version of the HowTo is for LVM 2 with device-mapper and LVM 1.0.8.

SQL Server provides a mechanism for returning different values in a SELECT clause based on Boolean conditions: the CASE statement. This statement resembles Visual Basics Select Case statement.

This document explains how to set up Debian GNU/Linux on a computer with your root partition on a RAID volume managed with LVM.

The Filesystem Hierarchy Standard (FHS) defines the main directories and their contents in most software systems using UNIX and Unix-like operating systems. It is a formalization and extension of common UNIX practices.

SQL DATEADD Function: Returns a new datetime value based on adding an interval to the specified date.

How to install Debian

This guide explains how you can install and use KVM for creating and running virtual machines on an Ubuntu 8.10 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM).

rtorrent is a BitTorrent client for ncurses, using the libtorrent library. The client and library is written in C++ with emphasis on speed and efficiency, while delivering equivalent features to those found in GUI based clients in an ncurses client.

In computer storage, logical volume management or LVM is a method of allocating space on mass storage devices that is more flexible than conventional partitioning schemes. In particular, a volume manager can concatenate, stripe together or otherwise combine partitions into larger virtual ones that can be resized or moved, possibly while it is being used.

This HOWTO describes the "new-style" RAID present in the 2.4 and 2.6 kernel series only. It does not describe the "old-style" RAID functionality present in 2.0 and 2.2 kernels.

There are ways to limit the number of user processes in a system. These limits can protect you mainly from your own mistakes. If a remote attacker is able to trigger a fork bomb in your system, you probably have a more serious problem than simply the lack of this limit.

Suppose we have a two-player game in which each player takes turn making his/her move. We assume that the game will always terminate in a draw, win, or loss. We can conceptualize the game as a tree consisting of all the possible "game board" configurations with the initial configuration as a root node. Each node in the game tree corresponds to a possible configuration of the game. A leaf node corresponds to an end game configuration: a win, loss, or draw.

The days of the plain filesystems like FAT32 and ext2 seem to have past. Newer operating systems are offering journal, 64-bit filesystems, with features like supporting terrabytes of filesizes or attaching attributed meta-data in them. Today we are interviewing (in a given set of questions) the main people behind IBM's JFS, NameSys' ReiserFS and SGI's XFS.

This tutorial is complete guide to DOM processing.

Welcome to Processing XML with Java, a complete tutorial about writing Java programs that read and write XML documents. It contains over 1000 pages of detailed information on SAX, DOM, JDOM, JAXP, TrAX, XPath, XSLT, SOAP, and lots of other juicy acronyms. This book is written for Java programmers who want to learn how to read and write XML documents from their code.

The entire book is available online. You can read every chapter and every page so you can see for yourself how well this book answers your questions such as, "Why does SAX truncate the text in my documents after a few thousand characters?" or, "How do I serialize a DOM Document object in an implementation-independent way?" I'll forego the usual hype. Check the book out for yourself. The entire book is here at Cafe con Leche. You can read every word of it, all seventeen chapters and two appendixes. If you like it, please buy a copy. I promise it's cheaper than printing all 1100+ pages on your laser printer.

I'm going to show you a base example that does everything that most documents need to do. It has a root element. The root contains another element that is its child. The root contains a comment too.
