Installing Ubuntu Or Fedora From A Windows Or Linux System With UNetbootin

Post date: October 7, 2007, 09:10 Category: Installing Views: 4822 Comments
Tutorial quote: UNetbootin is a tool that allows you to install various Linux distributions (Ubuntu, Fedora, Mandriva, OpenSuSE, Debian, ArchLinux) from a Windows or a Linux desktop over the internet (i.e., you do not need to burn the Ubuntu, Fedora, ... CDs). Unlike the Ubuntu installation with Wubi, real partitions are created during the installation. In the end, you have a dual-boot system (Linux/Windows or Linux/Linux).

High Performance MySQL

Post date: December 1, 2006, 04:12 Category: Optimizing Views: 6800 Comments
Tutorial quote: The operating system your MySQL server runs on and the server's configuration can be just as important to your server's performance as the indexes, schema, or queries themselves. In this chapter, we will help you understand how to tune your server to improve performance, as opposed to tuning schema or queries. We'll be looking at changes to your hardware, operating system, and MySQL configuration to see what effects they have on overall performance.

We assume that you've already made efforts to boost the performance of your queries. If you haven't done that already, stop now and read Chapter 4 and Chapter 5 to get a handle on optimizing your queries and your application code. Only then should you worry about server settings. Hardware is often not the solution to MySQL performance problems. Poorly optimized queries can slow you down far more than not having the latest CPU or SCSI disk. To put this in perspective, one of the MySQL AB trainers even says that changing hardware might, in the best cases, give you a 10-fold performance increase. But tuning queries (and schemas) can often give you 1000-fold performance increase. Seriously.

Some topics covered in this chapter are platform-specific. The authors' knowledge of the various platforms on which MySQL runs is limited. In many cases, you'll need to consult your local documentation for various operating system tools and specifics.

We start with an overview of the factors that limit performance and then look more in depth at RAID, hardware, and operating system issues. The chapter finishes with a discussion of techniques you can use to locate, identify, and fix bottlenecks.

User-Mode Linux

Post date: December 8, 2005, 13:12 Category: Software Views: 4742 Comments
Tutorial quote: One of the largest efforts involved with software engineering is testing the software to make sure that it works as designed. Testing can require several different types of system configurations and could require multiple instances of Linux. One way to create this type of environment is to use a virtual machine.

User-Mode Linux (UML) is a fully functional Linux kernel. It runs its own scheduler and virtual memory (VM) system, relying on the host kernel for hardware support. It includes virtual block, network, and serial devices to provide an environment that is almost as full-featured as a hardware-based machine. UML cannot destroy the host machine. Furthermore, the UML block devices, also called disks, can be files on the native Linux file system, so you cannot affect the native block devices. This is very useful when you're testing and debugging block operations.

The Perfect Desktop - Part 1: Fedora Core 6

Post date: February 22, 2007, 19:02 Category: Desktop Views: 7822 Comments
Tutorial quote: With the release of Microsoft's new Windows operating system (Vista), more and more people are looking for alternatives to Windows for various reasons. This tutorial is the first of a series of articles where I will show people who are willing to switch to Linux how they can set up a Linux desktop (Fedora Core 6 in this article) that fully replaces their Windows desktop, i.e. that has all software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions, and the best thing is: all software comes free of charge.

Installing Ubuntu/Kubuntu Dapper Drake on a Single/Multi-Boot RAID System

Post date: February 8, 2007, 20:02 Category: Installing Views: 3937 Comments
Tutorial quote: This guide describes how to install Ubuntu (Ubuntu+GNOME) or Kubuntu (Ubuntu+KDE) 6.06.1 LTS (Dapper Drake) on a single or a multi-boot RAID system. It is meant as a variation of Ubuntu Wiki FakeRAID HowTo document, but digested and with minimum commentary. Its goal is to allow new Ubuntu users to complete an entire installation within 30 minutes, almost entirely by copy and paste.

The Perfect Desktop - PC-BSD 1.5

Post date: March 20, 2008, 12:03 Category: Desktop Views: 9962 Comments
Tutorial quote: This document describes how to set up PC-BSD v1.5. This release is based upon FreeBSD 6.3 and uses KDE 3.5.8 as default desktop environment. Taken from the PC-BSD page: PC-BSD is a complete desktop operating system, which has been designed with the "casual" computer user in mind. It offers the stability and security that only a BSD-based operating system can bring, while as the same time providing a comfortable user experience, allowing you to get the most out of your computing time. With PC-BSD you can spend less time working to fix viruses or spyware and instead have the computer work for you.

Setting Up A Subversion Repository Using Apache, With Auto Updatable Working Copy

Post date: June 19, 2007, 02:06 Category: Miscellaneous Views: 3984 Comments
Tutorial quote: Subversion is a free/open-source version control system. That is, Subversion manages files and directories over time. A tree of files is placed into a central repository. The repository is much like an ordinary file server, except that it remembers every change ever made to your files and directories. This allows you to recover older versions of your data, or examine the history of how your data changed. In this regard, many people think of a version control system as a sort of time machine.

A Short Introduction To Apt-Pinning

Post date: March 24, 2009, 12:03 Category: Miscellaneous Views: 4183 Comments
Tutorial quote: This article is a short overview of how to use apt-pinning on Debian and Debian-based distributions (like Ubuntu). Apt-Pinning allows you to use multiple releases (e.g. stable, testing, and unstable) on your system and to specify when to install a package from which release. That way you can run a system based mostly on the stable release, but also install some newer packages from testing or unstable (or third-party repositories).
