User PPP Connections
"First of all, let's review a basic concept from the Clueless User's Guide series: everything on the Open Source computer is a file. In your /dev (device) folder is kept all sorts of "devices" which are linked there as files. A "device" may be nothing more than a particular protocol by which the kernel communicates to the hardware. During the lesson on Initial Setup, we talked about making sure the firewall had matching entries for ppp0 and tun0. Each of those is a protocol linked in your /dev folder. When you use KPPP to connect to the Internet, it uses the ppp0 device."

Integration: a real opportunity for Linux
The notion of "killer apps" fueling a platform's growth seems embeded in our technological culture, but those of us looking for this key to help fuel Linux's growth may be overlooking the biggest opportunity yet. The following editorial submitted to osOpinion/osViews indicates that "total system integration" is a huge opportunity that up until now has only been put into use to only a limited degree. Indeed it will be the platforms that can offer the tightest integration that have the largest growth potential.

So many worms, so little time
There is no single security countermeasure, or silver bullet, that can protect our networks completely. Over time the threats have grown in both number and complexity, while the timeframe for response has been shortened dramatically. What can we do?

Creating Websites Using Mac OS X
"While you could serve your web site off your Mac, there are a few reasons why you may not want to. First, your ISP may not appreciate it. Many make it hard, if not, impossible to share web pages. Another reason may be setting up a router to allow access to your Mac's web page. Every router is different and trying to explain how to do it on each one is a task I don't have the resources to complete."

GPS and Linux: A match made in heaven.
Whether you're wardriving, vacationing or building a Car PC, a Global Positioning System is a handy tool. Interacting with your GPS via your PC makes for an even better GPS experience. As a Linux user, GPS/PC integration can be somewhat sketchy. Vendors don't write software and drivers for Linux; it's probably safe to assume that the good folks over at Garmin would say something along the lines of "Lih-what?". Have no fear! Using your GPS with Linux isn't impossible! Check out this review over at LinuxForumsDOTorg of two fairly robust GPS navigation programs for Linux.

Genesis of a Linux guru
"Buer believed that Secureworks had to eliminate the need to do time-consuming reconfiguration on the client's network. He'd always been interested in Linux, and he had an idea. Why not use proxy ARP to simplify the install procedure? Proxy ARP allows a firewall to respond to address resolution protocol (ARP) requests for hosts other than itself. This is far less intrusive than standard address resolution requests on the network, which meant the beginning of a simpler installation procedure for Buer and Secureworks."

Interview KPDF Icon Contest
"I'm Enrico Ros, hacking on KDE on spare time which is a fun and creative thing to do. Now I'm involved in KPDF 'restyling' that means bringing it to a good level or at least made it meet users expectations. As of now most of the frequently requested features have been implemented (search, links, continuous mode, centered pages, better zooming, faster thumbnail generation, ..)."

Richard Stallman Meets the World Scout Bureau
"Stallman: It's not who was the developer, it's whether he respects your freedom that matters. If you want to live in freedom, you've got to reject software that tramples your freedom. You shouldn't stand for software that keeps you helpless or forbids helping others. When a program is free software, that means you and others can see what it does. So you can listen to other people in the community who have studied it and used it and thus decide whether you want to use it. If you really are concerned about what the program does, you can read the code yourself."

Know How To Prevent Race Conditions
Using a stolen password, Mallory managed to log into an important server running Linux. The account was a very limited account, but Mallory knew how to cause trouble with it. Mallory installed and ran a trivial program with very odd behavior. Learn what a race condition is and why it can cause security problems.

The GIMP 2.0
"In the early days of Linux, users had modest needs to create graphics, so the then-nascent GNU Image Manipulation Program (GIMP) served them well. However, as Linux and the GIMP became popular, more sophisticated users -- even some graphics professionals -- began to rely on the GIMP for their day-to-day needs. As often occurs, as demand for the GIMP grew, so did the number of feature requests. Fortunately, the GIMP developers worked hard to keep up with expensive, proprietary image editing software available on other platforms, and today, the GIMP is "the Photoshop of Linux," a category-killer application."

Making XP a Welcome Guest on Mac
"After testing it for several days, I'm very impressed. Virtual PC is fast and stable. It is remarkably full-featured and works pretty seamlessly. Microsoft is often knocked by Mac users, but Virtual PC proves the company can turn out very good software for the Mac. (Microsoft acquired Virtual PC from Connectix in 2003. Version 7 is the second update of the software from Microsoft)."

Responding to Disk Errors on Both Root Mirrors
"This document was written for system administrators who are required to respond to errors for disks under the control of Online Disk Suite (ODS) or, in later versions, Solaris Volume Manager (SVM) software. In this example both root mirrors are failing. However, as shown here, it is not always necessary to replace the disk(s). This Tech Tip details the steps to take to identify and resolve the issue. "

Knoppix from non-bootable CD-ROM
"The biggest hurdle is the kernel size starting with release 2.6.7. In the 2.6.6 release, the Knoppix kernel would fit on a 1.4M diskette. Now you need to format the diskette to 1.68M - the same size Microsoft uses occasionally for its diskettes. For that purpose, you can use winimage under Windows, fdformat under DOS or superformat/fdformat under Linux. Good luck to you because diskettes sold for the 1.4M capacity do not necessarily agree to a flawless format at higher capacity. My experience is that you need a box of ten to get one such tolerant diskette. If you want strict verification, use winimage and you will see the massacre."

California Air Resources Board's Secrets Revealed
"In speaking with Bill, I discovered a model state agency that has taken advantage of Linux and open-source software extensively for over a decade. The team believes ARB is first in the country in air quality management and first in the state in open-source IT solutions. When I first spoke to Welty, he immediately pointed out that his team is responsible for the agency's IT success. He points to Bill Fell, Harry Ng and Narci Gonzales as the proponents, visionaries and programmers who make open-source systems work at ARB."

Statistical programming with R: Part 2
In the second of a three-part series, David and Brad build on their first article on R, a rich statistical environment, released as free software. R is both a strongly functional programming language and a general environment for statistical exploration of data sets. Now that our data is shipshape, we will delve into the functionality of the language.
