Self-Managed Data Buffer Memory
The C programming language defines two standard memory management functions: malloc() and free(). C programmers frequently use those functions to allocate buffers at run time to pass data between functions. In many situations, however, you cannot predetermine the actual sizes required for the buffers, which may cause several fundamental problems for constructing complex C programs. In this article, Xiaoming Zhang advocates a self-managing, abstract data buffer. He outlines a pseudo-C implementation of the abstract buffer and details the advantages of adopting this mechanism.

World's Smallest Secure Web Server
"Sizzle runs on the Berkeley/Crossbow "motes" -- battery-powered, wireless devices equipped with an 8-bit microprocessor, 128KB of FLASH and a mere 4KB of RAM. While many small web servers have been demonstrated previously, none has addressed the capability of secure communication within such tight resource constraints. Sizzle implements the industry standard security protocol, SSL, used to protect Internet-based transactions like stock trading, e-commerce and on-line banking."

Object databases: Q&A with key movers at db4object
"While the traditional relational database market has largely resisted open source databases, the database world overall is a dynamic market full of change and opportunity. Berkeley DB and MySQL are notable open source successes in the embedded market and the market for database-backed Web sites. To that mix, db4objects hopes to become the newest success story, with its object database. NewsForge sat down for a Q&A with db4objects CEO Christof Wittig and Chief Software Architect Carl Rosenberger to get an overview of their strategy."

Installing a Virtual Honeywall using VMware
The Honeywall CDROM makes the implementation of a GenII Honeynet Gateway easier. Furthermore, if it is installed on a virtual machine, it will also include the many advantages that a virtual machine environment offers. This paper therefore, explains how to go about configuring VMware to deploy a Honeywall. read more (Article is a PDF file)

Programming the cache on the PowerPC
While many programs can obtain acceptable performance by simply letting the processor manage its own caching, programs with special requirements may obtain dramatically improved performance by giving the processor explicit instructions and manipulating the cache directly. More typically, boot firmware may need to flush and enable the cache.

The Easy Way to the ILife
"There are plenty of very good guides to choose from. O'Reilly Media's Missing Manuals series is perhaps the most popular, and Peachpit Press' Visual QuickStart guides are highly regarded. But I like Jim Heid's Macintosh iLife '04, a 300-page guide to Apple's iLife software suite."

Apple to drop sub-$500 Mac bomb at Expo
"e new Mac, code-named Q88, will be part of the iMac family and is expected to sport a PowerPC G4 processor at a speed around 1.25GHz. The new Mac is said to be incredibly small and will be housed in a flat enclosure with a height similar to the 1.73 inches of Apple's Xserve. Its size benefits will include the ability to stand the Mac on its side or put it below a display or monitor."

Use Your Digital Camera with Linux
"For years, I've wanted a digital camera. Both my father and brother had one; why not me? Then one day it happened: I had been working a new contract for about a month when the boss said it was time we met. He was in New York City and here I was in Ottawa. Coincidentally, NYC-bug (pronounced "nice bug") had invited my girlfriend to go see Eric Allman and Kirk McKusick talk at a BSD user group meeting. Of course, being the natural born tourist that I am, I had to buy one immediately."

Gentoo for All the Unusual Reasons
"I have a confession to make. I use Gentoo Linux. My colleagues at the various Linux User Group meetings I attend think I'm nuts. Everyone knows that Gentoo is a source-based Linux distribution. Gentoo's reputation (in large measure pushed by the people who develop the distribution) is that it's for people who want super crazy optimizations, and it really is suitable only for those who use desktops. In truth, Gentoo is ideal for a whole bunch of other, unexpected, reasons. Much to my surprise, people actually are using Gentoo in production environments for these very reasons."

Proactive Patch Management
"Some may say that availability and perhaps serviceability of systems will be improved. The difficult question to answer is, by how much? Technical people are also aware that patches are not bug-free software either. A number of patches are withdrawn each year, and a number of alerts are released to inform users about bad patches identified within their system environment. Thus, the risks related to the introduction of patches into system environments come from:"

Better programming through effective list handling
Singly linked lists are a powerful abstraction that allow programmers to represent numerous types of data; extending those lists to handle arbitrary data types can offer effective tools for processing data. This article looks at these processes and examine the Lisp variation Scheme, an easy-to-use list-oriented language that delivers list-manipulation capabilities without the complexities of C.

Tal Herzberg, the Long Arm of the DAW
"A digital audio workstation, like a guitar or piano, is a musical instrument," says Tal Herzberg, a Grammy-winning engineer, producer, programmer, and mixer who was one of the first to embrace computers for music. "Most musicians I know today use digital production tools in their creative processes. The ability to hear ideas played back practically in real time is addictive."
