Recover Data From RAID1 LVM Partitions
This tutorial describes how to rescue data from a single hard disk that was part of a LVM2 RAID1 setup. Why is it so problematic to recover the data? Every single hard disk that formerly was a part of a LVM RAID1 setup contains all data that was stored in the RAID, but the hard disk cannot simply be mounted. First, a RAID setup must be configured for the partition(s) and then LVM must be set up to use this (these) RAID partition(s) before you will be able to mount it. I will use the Knoppix Linux LiveCD to do the data recovery.

PowerBASIC/DOS and Linux
How to use PowerBASIC/DOS on Linux:

"A combination of Linux and the DOS version of the PowerBASIC compiler is a powerful solution for simple (and not so simple) programming tasks. You can create blazingly fast fully multi-user databases and other applications that run under Linux. As PowerBASIC was designed to run at reasonable speed on XT's, 286's and 386's, it runs like nobody's business on modern multi-gigahertz CPU's. It is also an easy way to write programs on Linux machines that can be instantly copied to and run on MS Windows with no changes required at all, as many versions of Windows can run DOS programs natively. (I am not sure if DOS programs can be run on Windows Vista.) This article describes how to get everything working on Linux, and provides handy programming tips for integrating a DOS program written in PowerBASIC with the rest of your desktop."

Slim Linux laptop has potential
Looks nice but can you get to a shell?
"The Foleo has been pitched as a "revolutionary product category" ever since Palm began hiring Linux developers more than a year ago. When Palm unveiled the device last month, it breathlessly billed the Foleo as the first of a "new class" of products likely to go down in history as Palm's best-selling ever -- more popular than the Treo smartphone, and more popular than the original "Palm Pilot." "

OpenMoko Neo1973 - a Linux based phone
OpenMoko is a GNU/Linux based open software development platform. What this means for the lay person is that using OpenMoko software development kit, phone manufacturers will be able to bring out mobile phones which have more or less the same features of the now widely known iPhone from Apple and much more - all this under an Open license powered by GNU. This also means that for the first time there is potential for you to be completely free from being tied up with one mobile carrier or even a single phone manufacturer (read Apple) for want of anything better.

MPX for X Server on Linux
"The Multi-Pointer X Server (MPX) is a modification of the X Server. A standard X Server only provides one mouse cursor (pointer) and one keyboard focus, regardless of the number of input devices connected. MPX provides the user with multiple mouse cursors and multiple keyboard foci. Multicursor applications have been developed in the past but MPX is the first implementation of a multicursor windowing system (or a multicursor X server)."

Virtual Hosting With PureFTPd And MySQL
This document describes how to install a PureFTPd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database.

Optimizing AIX 5L performance through Disk I/O
While disk tuning is arguably less exciting than CPU or memory tuning, it is a crucial component in optimizing server performance. Learn more about direct I/O, concurrent I/O, asynchronous I/O, and best practices for each method of I/O implementation.

Take Charge of Your Architecture
The architecture you think you have is often different than what you actually have. Itís time to take charge of your architecture and learn how you can discover deviations by writing tests using JUnit, JDepend, and Ant to discover problems proactively instead of long after the fact.
