Linux vs. BSD, What's the Difference? Dru Lavigne. Linux mavens are usually pretty sure they'll never go back to (or start using) Windows. They may like Mac OS, but usually don't jump ship for that either.
But how about the other open source Unix descendant, BSD? Dru Lavigne offers a basic primer on what's different in PC- BSD for a Linux user, and what's better. An Introduction to Linux Audio. John Littler. OSS. ALSA. JACK. Linux certainly has enough ways that you can get access to the sound subsystem. But which one to use, and how? John Littler takes us on a guided tour of Linux Audio, complete with code.
A Simple Introduction to Device Drivers under Linux. Valerie Henson. For many seasoned Linux developers, device drivers still remain a bit of a mysterious black art practiced by a select few. While no single article could possibly attempt to covered everything there is to know about writing drivers, Valerie Henson gives us a brief taste of what's involved, by implementing a device to return "Hello World" using all the major driver frameworks. Optimizing Linux System Performance. Swayam Prakasha. Wringing the value out of every processor cycle on your machine required a variety of approaches.
Sure, your code has to be efficient, but you also have to have your disks configured correctly, and a multitude of other things. Swayam Prakash provides a guide to some of the lower hanging fruit you can pick. Semaphores in Linux. Vikram Shukla. Semaphores are one of those things that most programmers have heard of, but may not have ever used. But if you're using threads under Linux, it's one of the best ways to keep everyone in sync.

John Littler examples how the upgrade works and walks you through setting up VOIP and Asterisk. When Linux Runs Out of Memory. Mulyadi Santosa. Memory is a precious commodity in computers. Generally the more you have, the better.
Yet your application has to run alongside other applications, and each wants its own area of memory. What happens when there's not enough to go around? Mulyadi Santosa explores the memory management principles in the Linux kernel to explain how the Out of Memory killer works- -and how to avoid it. Virtualization and the POWER5 Architecture.
Ken Milberg. Virtualization is a trendy topic in the server room now, especially as commodity computers begin to support features that mainframes have had for decades. Mainframes aren't standing still, however; IBM's POWER5 architecture supports powerful virtualization features on AIX..
Linux. Ken Milberg describes some of the benefits of the recent work on this platform. Degrees of Openness. Adrien Lamothe"Open" is a word too important to apply merely to source code. Although open source code is important to free and unfettered computing, openness encompasses far more components of a computing system.
Adrien Lamothe explores other degrees of openness and their implications. Rediscovering Bluetooth.
Guylhem Aznar. Bluetooth is a powerful protocol. Its advantages over Wi. Fi make it capable of doing a lot more than most people imagine- -yet few people understand how to get the benefits. Guylhem Aznar walks through enabling Bluetooth on a Linux PC and connecting to useful devices.
Four Tough Lessons of System Recovery. KIVILCIM Hindistan.
KIVILCIM Hindistan recently migrated to a new laptop and promptly destroyed his partition table. Flailing around with false laziness taught him the true value of true laziness.
Here's a real- life tale of Knoppix rescue and a cautionary tale about troubleshooting. Linux on the Nokia 7. Internet Tablet. by John Littler. Nokia's 7. 70 Internet Tablet is more than a phone, according to John Littler. It's a Debian GNU/Linux system.
This makes it a prime target for hackers. Littler explores some of the built- in utilities and some of the other tricks you can use. Indie Podcasting with Open Source. John Littler. Linux has a reputation as a multimedia lightweight. That's undeserved; there are plenty of powerful, useful, and usable applications to meet most of your media needs. For example, it's possible to become an independent podcaster with a little bit of equipment and experience.
John Littler shares his advice on podcasting with open source. Switching Back to Desktop Linux. Almost everyone at O'Reilly owns an i. Book or Power. Book and almost everyone runs Mac OS X. It's not everyone's ideal operating system, however. Recently, free software editor chromatic explained to Mac editor Derrick Story why he switched back to desktop Linux.
Here's what he wants in a usable Unix desktop. How Shellcodes Work. Peter Mikhalenko. Buffer overflow problems are well- known. Fewer people know how exploits can help attackers execute their malware through buffer overflows and other holes. Peter Mikhalenko walks through the construction and refinement of a shellcode to show how they work so that you can protect your machines. Managing Disk Space with LVM.
Bryce Harrington. Kees Cook. Linux's Logical Volume Manager (LVM) allows you to create virtual disk partitions out of one or more hard drives. This makes it easy to manage growth in filesystems.
Combined with RAID, it provides a nearly unbeatable way to keep your files safe and available. Bryce Harrington and Kees Cook show how to configure LVM, how to combine it with RAID, and how to use it on desktop machines too. Installing Software on Debian.
Edd Dumbill. Debian GNU/Linux is a powerful and popular community- developed Linux distribution- -and the basis for several other useful and usable distributions. One of the reasons for its popularity is the ease of installing and maintaining software. Edd Dumbill, Debian developer and GNU/Linux advocate, shows how to use Debian's tools to find and install software packages. Secure Your Linux Server.
Aaron Brazell. Linux is a powerful and popular operating system kernel. That popularity means you might be running it even if you're not a dedicated Unix administrator or high- powered programmer.
That doesn't mean that rock- solid security is out of your reach, though. Aaron Brazell shows how to make Red Hat 9 (and other Linux distributions) much more secure in a few easy steps.
Fine- Tuning Kubuntu. Carla Schroder. Ubuntu is a well- maintained, well- organized Linux distribution. Kubuntu adds the popular and powerful KDE desktop environment. As nice as Kubuntu is, the default installation doesn't fit every user.

Josh Glover. Now that we have moving paddles for our SDL Pong clone, the only thing standing in the way of some real fun is making the ball move (and adding scorekeeping). Josh Glover delivers the finale to his three- part Pong hack by showing you how to add these last two elements to finish off your very own table tennis computer game. Retro Gaming Hacks, Part 2: Add Paddles to Pong. Josh Glover. In part one of this three- part series on hacking Pong, Josh Glover detailed how you can write your own Pong clone, using SDL. So what's next? Adding the paddles. Today Josh walks through how, with the help of sprites, you can create and animate player- controlled paddles for your Pong clone.
