Welcome to the post-Super Bowl Linux newsletter! It's also the post-LinuxWorld Expo newsletter, but the former had more television coverage, for some reason. Maybe next year. Here's what's new on ONLamp.com this week.
In a plausably deniable coincidence, Iljitsch van Beijnum, author of the BGP book, wrote How to Get Rid of DDoS Attacks. There are three common techniques, each with advantages and drawbacks--but Iljitsch has a fourth. Look for a short article from him on the weekend's DDoS.
Our well-loved columnist Dru Lavigne took a holiday over the holidays to explore some of the nooks and crannies of her FreeBSD machine. Odds and Ends also reveals one source of her knowledge. Besides useful small utilities for learning more, Dru also explores a couple of timesinks and diversions included with the system.
One of the nicest bits of Mac OS X is that it has quite a bit of Free Unix goodness at its core. One of the most frustrating bits is that it has some odd differences. Building software can be tricky. Good news for PHP hackers today, though--Jason Perry's article, PHP's PEAR on Mac OS X, explains how to build, configure, and use the popular PHP repository on Mac OS X.
Finally (and more eerily), Iljitch also contributed the final installment of his Traffic Engineering column. This time, Queueing, Traffic Shaping, and Policing explains how to improve performance for specific applications--and more.

Several weblogs of the past week have featured thoughts and impressions from last week's LinuxWorld Expo. What's coming this year? Read and find out!
Now's also the time to mention this summer's upcoming OSCON. (Downtown Portland, Oregon is quite nice in the summer--and the hotel's within walking distance of almost anything you could want.) The deadline for proposals is near, so get your tutorial and talk ideas in soon! (Your editor is as guilty of procrastination as anyone ... except maybe Michael G. Schwern.)
As a teaser, upcoming articles include practical Bayesian spam filtering, emulating SMP on single-processor Linux systems, more games (SDL programming, Exult, Egoboo, FreeSCI), advanced OOP with Python, Ruby, and UML.
Until next week,
PHP 4.3 and Mac OS X
The recently released version 4.3 of PHP lets you customize it with your favorite configuration. Adam Trachtenberg, coauthor of PHP Cookbook, shows you how to download, configure, and install your very own PHP on Mac OS X.
Odds and Ends
The end of year holidays bring a chance to reconnect with friends, family, and Unix. At least, they do in Dru Lavigne's household. The FreeBSD columnist shares a few odds and ends on getting to know Unix better.
How to Get Rid of Denial-of-Service Attacks
Getting rid of DDoS attacks means filtering traffic. It's complicated by spoofing and congestion -- but Iljitsch van Beijnum, author of BGP, has three modest proposals.
The nice thing about software is that you can patch it to fix problems. The tricky thing about software is that you have to patch it to fix problems. Your systems are only as secure as your patching strategy allows. Jacek Artymiak explains how to apply patches to your OpenBSD machines.
Emmanuel Dreyfus Interview
A recent update of the NetBSD Mach and Darwin binary compatibility page left several people wondering if OS X apps now ran nearly- natively. Emmanuel Dreyfus, one of the leaders of the project, has graciously agreed to an interview. What's this binary compatibility and what does it mean?
