Dept. of Homeland Security Site Switches to Linux
News Forge reports that the Deptartment of Homeland Security's site has switched to Linux.
"An experienced sysadmin can just do so much more to lock down a Unix-based operating system, especially Linux," says Beale. "Windows 2000 doesn't offer either the same kind of granularity of configuration or the equivalent ability to inspect pieces of the operating system."

PHP and MySQL Web Development
Slashdot looks at the book: PHP and MySQL Web Development.
"Starting with the "PHP Crash Course," the reader quickly learns the syntax and language constructs of PHP. The following five chapters focus on topics such as arrays, string manipulation, writing functions and object-oriented PHP. This provides a solid foundation in PHP before moving on to the intricacies of MySQL. This section is very hands-on, using realistic examples, which could be expanded upon as skills progress."

Larry McVoy on BitKeeper
Linux World talks to Larry McVoy about BitKeeper, kernel development, Linux Torvalds, and Bruce Perens.
"The story of how BitKeeper has come to be Linus Torvalds' (and many other kernel hackers) tool of choice in maintaining the Linux development tree is worthy of a book. Here's the Cliff Note's version of McVoy's contribution to Linux kernel development, BitKeeper, and countless hours of flaming on the role of open source and proprietary software."

IBM Linux Applications
I saw this link over on NewsForge today. IBM is giving away 4 CDs full of their middleware. It includes the newest levels of DB2 Universal Database, WebSphere Application Server, Lotus Domino, WebSphere Studio Site Developer, WebSphere MQ, Tivoli Access Manager, and bunch of Linux tutorials, white papers and tools to help you port your Unix apps to Linux.

An Overview of the Sun Microsystem Firewall
Security Focus takes a look at SunScreen.
"SunScreen provides for packet filtering as well as authentication and data encryption. The SunScreen software provides for both a packet filter as well as the capability to create IPsec-based VPNs. Administration of the SunScreen system is provided through a GUI or a command-line interface. The SunScreen system is composed of two parts: the screening system and the administration system."

Largefile Support Problems
Freshmeat talks about largefile support problems.
"The Unix98 standard requires largefile support, and many of the latest operating systems provide it. However, some systems still chose not to make it the default, resulting in two models: Some parts of the system use the traditional 32bit off_t, while others are compiled with a largefile 64bit off_t. Mixing libraries and plugins is not a good idea."

Remote Gkrellm over SSH
Linux Orbit contributing editor Dan McCombs gives us the lowdown on running the Gkrellm system monitor remotely over SSH:

"It's nice to have a server, router or firewall tucked away in a closet or in a dark corner of a room and still be able to access it over your local network. But what about monitoring it? Keeping an eye on a local computer is easy with Gkrellm, so why not a remote computer? In this Mini-HOWTO I'll show you how to use X11 forwarding over SSH to run a Gkrellm on your remote computer and have it display on your local computer, securely!"

OpenBSD's Battle For UltraSparc III Documentation
In late November of 2002, OpenBSD creator Theo de Raadt announced on the project's mailing lists that after over a year of attempting to obtain useful UltraSparc III documentation, they had still not made much headway. In the email he rallied the OpenBSD community to help out, asking them to contact the people within Sun responsible for providing such information. C/Net reported on this in their story titled, Open-source clan in spat with Sun. The UltraSparc III is Sun's third generation 64-bit RISC architecture based processor.
Sun boasts their UltraSparc III as an "open" architecture, yet seem to recognize that there is insufficient information freely available for the open source community to support it with operating systems. I have been told that the required documentation does exist, however, with a Sun part number of 805-0408-05-P. An early version of this manual was allegedly made available to Linux developers once a Confidential Disclosure Agreement was signed (Sun's version of a Non-Disclosure Agreement), however no such offer has been made to the OpenBSD team, an offer that if made is likely counter to the project's goals.

I attempted to discuss this issue with Danese Cooper who works in Sun's Open Source Programs Office, with as of yet limited results. My goal is to gain a clear understanding of Sun's official position on this situation, something that to date they seem unwilling to discuss with me. My continued attempts to get direct answers are described here.

Vive Java et Blackdown!
Linuxworld takes a look at Java.
"Java performance on Linux has yet to reach its potential. That said, I am still impressed with the current state of Java for client applications. If you want to get an feel for how much I believe Java has improved, here's a point of reference ("benchmark" is too strong of a term) that should remove all doubt."

Odds and Ends
On Lamp talks about some Unix odds and ends.
"At some point, I retired those notebooks and started to maintain notes in my home directory. There are several ways to keep track of your own experimentations. The first is to record your input and resulting output using the script command. For example, I can keep track of the date I did some experiments with snort:"

Book Review: Apache Administrator's Handbook
There are lot of online texts covering Apache administration and Apache security, but from my perspective a book laying on your shelf gives a better and easily accessible reference. It is always better to have all the relevant information on one place, rather than browsing the net and trying to search through tons of white papers, articles and FAQs. Written by Apache experts, "Apache Administrator's Handbook" is a valuable book for Apache administrators and for people that want to go in-depth with knowledge about this powerful web server.

SimPy Simplifies Complex Models
This article takes a look at SimPy, a Python package that allows you to easily create models of discrete event systems. There is some novelty involved in the way we think about this style of programming, but simulations are useful for understanding the behavior of resource-limited real-life systems. SimPy provides a simple Python tool for various types of modeling from limited bandwidth networks, automobile traffic behavior, market and commercial optimization, biological/evolutionary interactions, to other "stochastic" systems.

Developing cfperl, From the Beginning
Perl expert, Ted Zlatanov embarks on a new coding project to create cfperl, a cfengine interpreter written in Perl. This project explores the possibility of how cfengine could benefit from features present in Perl, in a simpler way. By the end of the article you will be familiar with Ted's approach, ideas and planning to the cfperl project and how it might apply to your own projects.
