Unix+clones Emulating an OS with qemu
Post date: May 22, 2005, 04:05 Category: Emulation Views: 86
Tutorial quote: When you want to emulate a PC with a complete operating system on your computer, the most heard answer would be VMWare. Sure, for Linux, there is wine, but that package is targeted to handle only window$ and not all programs are supported. No, I'm talking about simulating a complete OS on a virtual PC with virtual hardware.

Although VMware does an almost perfect job at it, it isn't free software. Time to see what the Open Source community has to offer. That's when I stumbled upon qemu. Let's have a look at the possibilities.

Unix+clones Apple's G5 versus x86, Mac OS X versus Linux
Post date: June 3, 2005, 23:06 Category: Benchmarks Views: 117
Tutorial quote: This article is written solely from the frustration that I could not get a clear picture on what the G5 and Mac OS X are capable of. So, be warned; this is not an all-round review. It is definitely the worst buyer’s guide that you can imagine. This article cares about speed, performance, and nothing else! No comments on how well designed the internals are, no elaborate discussions about user friendliness, out-of-the-box experience and other subjective subjects. But we think that you should have a decent insight to where the G5/Mac OS X combination positions itself when compared to the Intel & AMD world at the end of this article.
OSX A mini-guide to Mac OS X for new Mini owners
Post date: April 12, 2005, 13:04 Category: Miscellaneous Views: 78
Tutorial quote: One thing the Mac mini does not have is a comprehensive “welcome to OS X” guide. Printed documentation included with the mini is scanty — primarily EULA and warranty information, and Apple has never been one for flashy tutorials. That’s why we at Ars have pulled together a short list of things every newcomer to Mac OS X needs to know.

This guide is not intended to be comprehensive and answer every conceivable question Windows and Linux users will have about their new platform. What it does intend to do is give you the lowdown on some basic things: window management, accessing your Windows box from the Mac, and application behavior.
OSX Mac OS X Server Migration Guide

Tutorial quote: This guide contains the following chapters:

Chapter 1, “Migrating the Previous Version of Mac OS X Server,” details the steps to follow if you have the previous version of Mac OS X Server and want to migrate to the new

Chapter 2, “Migrating Macintosh Manager or At Ease for Workgroups,” explains the steps involved in migrating existing Macintosh Manager or At Ease for Workgroups users,
workgroups, and documents to Mac OS X Server.

Chapter 3, “Migrating AppleShare IP,” provides information about migrating existing information from an AppleShare IP server to Mac OS X Server.
Ubuntu Installing Windows XP/2000 in Free VMWare Player
Post date: November 27, 2005, 12:11 Category: Miscellaneous Views: 216
Tutorial quote: This guide will allow you to install Windows XP or 2000 solely with the VMWare Player. For the uninitiated, VMWare released a free application that allows users to run, but not create virtual machines. Using QEMU, we will create an environment suitable for use with the player.

As a side-note, I'd like to point out that VMWare makes quality software. If you require additional functionality, consider upgrading to Workstation.
Unix+clones Using MySQL to benchmark OS performance
Post date: April 12, 2005, 03:04 Category: Benchmarks Views: 93
Tutorial quote: It seems to be an exciting time for *nix operating systems, with a number of them recently releasing new versions that bring the addition of expanded features and claims of improved performance. If you're using GNU/Linux, OpenBSD, NetBSD, FreeBSD, or Solaris as a database server, you've probably recently considered an upgrade or switch to another OS in that list due to marketing hype and hearsay. This article will show you how to benchmark operating system performance using MySQL on these OSes so you can find out for yourself if you're missing out. While this may not necessarily be indicative of overall system performance or overall database application performance, it will tell you specifically how well MySQL performs on your platform.

The following operating systems were used for the comparison testing:
- FreeBSD 4.11
- FreeBSD 5.3
- NetBSD 2.0
- Linux 2.6
- Linux 2.4
- Solaris 10 x86 (build 69)
- OpenBSD 3.6
Unix+clones Learn REXX fast
Post date: August 31, 2005, 21:08 Category: Programming Views: 114
Tutorial quote: If you’ve programmed under IBM operating systems, you’ve undoubtedly heard of Rexx. Rexx is the scripting and command language IBM bundles with all its mainframe, mid-range, and lower-end operating systems. What you might not be aware of is that Rexx also runs on almost every other operating system in the known universe. You can download Rexx free for all versions of Windows®, Linux, UNIX®, BSD, Mac OS, and DOS, and many other systems. It even runs on the three major operating systems for handheld devices: Windows CE, Palm OS, and Symbian/EPOC32.

What this means is, if you learn Rexx, you’ll know a scripting language that runs everywhere from mainframes to handhelds—and everything in between. Rexx is a general-purpose language that's powerful enough for mainframes yet flexible enough for other platforms. Best of all, Rexx is easy to learn.
