OpenBSD PF Developer Interview
"It was around November 1999 when I installed OpenBSD (2.5 by then) for the first time. I was working at a small company and we were looking for an OS to use as an Internet gateway. I didn't have much prior experience with Unix, but after a while, that gateway handled most network services we needed. Since then, I run OpenBSD on all servers and desktops I use."

CARP your way to high availability
"CARP is an improved version of the Virtual Router Redundancy Protocol (VRRP) standard. The latest protocol to help provide high availability and network redundancy, it was developed because router giant Cisco Systems believes that its Hot Standby Router Protocol (HSRP) patent covers some of the same technical areas as VRRP. To avoid legal conflicts, Ryan McBride (with help from Michael Shalayeff, Marco Pfatschbacher and Markus Friedl) designed CARP to be fundamentally different. "

Modeling a database with Rational XDE Developer
A data model provides application developers a much better understanding of the overall application architecture, even though generally speaking they are not required to know in-depth about database architecture details. A database designer can use a tool like Rational XDE to model and visualize the database, ensure database rules, add different database objects, and play around with relationships. This article shows you the basics of how to model a DB2 database using Rational XDE Developer for Java.

Desktop Brawl
"Computing technology evolves at an astounding speed. AMD now has its Athlon 64-bit chip, which probably beats the G5 (we didn't have one to test). But at press time there were rumors that Apple was set to introduce a 2.6-GHz G5 within weeks, likely leapfrogging the competition again. Who's fastest? We suppose it depends on when you ask and what tests you run."

iChat Knows Where I Am
"Anyway, I realized that my PowerBook knows where it is, because it sees the AirPort Base Stations that are around me. At home, it locks onto my home AirPort network, and at work, it locks on to the work network. So I decided to write an AppleScript that remembered to set my status on iChat AV, even when I forgot. It finds out what Base Station my PowerBook is attached to, and based on that, it sets my iChat AV status."

Investor dumps SCO
"The major speculator backing The SCO Group's legal jihad against Linux wants its money back. Marin County, California-based equity fund BayStar Capital invested $50 million in SCO back in October, confident that the Utah firm had a strong legal case. Now Baystar says SCO has breached the agreement and wants to redeem its investment, which takes the form of 20,000 shares of SCO's Series A Convertible Preferred Stock. "

What follows is an email interview conducted over the last few days.

Introducing Cfengine
"Cfengine, developed by Mark Burgess at Oslo University College, is one of the most powerful system administration tools available today. In a useful deviation from most scripting tools, cfengine allows you to describe the desired state of a system rather than what you should do to a system. Cfengine itself takes care of testing compliance with that state and will do its best to correct any misconfigurations."

Verifying public keys
"Verification is part of any security system. SSH, FTP, POP, and IMAP servers ask for your password before it lets you log into the machine, get your files, or snag your email. NTP can be configured to require keys before it'll let you mess with it's clock. CIFS requires a password or kerberos tickets before granting you access to shares."

Reflections on Trusting Trust
"More precisely stated, the problem is to write a source program that, when compiled and executed, will produce as output an exact copy of its source. If you have never done this, I urge you to try it on your own. The discovery of how to do it is a revelation that far surpasses any benefit obtained by being told how to do it. The part about "shortest" was just an incentive to demonstrate skill and determine a winner."

Weathering a Storm
"Since the Tomcat migration was completed in June 2002, Weather.com has been able to scale to more than 55 million page views per day when big winter storms or hurricanes drive usage spikes, according to Agronow. If he ever encounters a similar situation, Agronow says, "I would like to see proof from the vendor that their solution can perform at the capacity level we needed, even if it's in the lab. I guess I was a little too trusting."

The Myth of the Secure Operating System
"He added that, "At the very least, from the all-important network perspective, unlike Windows, Mac OS X ships with nearly all Internet services turned off by default," and "unlike Windows, Mac OS X requires an administrator password to change certain configurations, run the system updater and when installing new software."

Planning for Disaster Recovery on LAMP Systems
"The problem with our sort of database applications is that they weave themselves into the Linux system configuration. We add definition blocks to the configuration files for Apache, MySQL, Samba, et al. We create system-wide environment variables in user shells and insert symbolic links into the filesystem. Every time we rebuild a system we have to make the configuration changes anew. The potential for error is large, even assuming we remember all the steps."

NVIDIA GeForce 6800 Ultra Performance Leap
"The new NV4x design is supposed to make all these weaknesses a thing of the past. The first card based on this design that will come to market is the GeForce 6800 Ultra. This card outshines its predecessor, the FX 5950 Ultra, in practically every category - and not just on paper! "
