Exploring the New LPI 101 Exam
Unix Review takes a look at the LPI 101 exam.
"This month, I will take an in-depth look at the new 101 exam and the topics you must focus on to prepare for this exam. To create this in-depth coverage, I started with the chapters from two books that were written for the initial exams (and are no longer published) and placed them online."

Daemons Running Amok? Daemontools to the Rescue!
Okay, self-serving plug here- still, I think it's a useful howto :) I like DJ Bernstein's software, the downside is the documentation tends to be sparse and cryptic. It makes sense after you figure things out. daemontools is very nice and fast for managing services, and provides a consistent administration interface across all Unixes. One of its nicest features is automatically restarting services that die unexpectedly. Hopefully this will help users get it up and running with a minimum of vexation. See it here.

Understanding the Microprocessor
Arstechnica brings us: Understanding the Microprocessor.
"As a result, I always get feedback from people who express regret that there were portions of my articles that they didn't understand due to their lack of background in the material. This is unfortunate, and for some time I've considered doing a more generalized introduction to the basic concepts in computing. Events have recently conspired to afford me that opportunity, hence the present article, which is the first in a series on the basics of microprocessor technology."

Barbarians at the Gate
Security Focus talks about Distributed Denial of Service attacks.
"Although discussed in security circles for some time before that, this was the first prolonged example of a DDoS, and prevented legitimate traffic from reaching major sites for several hours. Yahoo, eBay, Buy.com, and CNN were but a few mjor sites who were inaccessible to their customers for extended periods of time. Now, almost three years later, can it be that we're still vulnerable? Unfortunately the answer is yes. This article will explain the concept of DDoS attacks, how they work, how to react if you become a target, and how the security community can work together to prevent them."

A Quick Look at the Fastest Apple PowerMac
Ace's Hardware has a new review online that takes a look at a dual 1.25 GHz Apple PowerMac. Though time with the unit was limited, the system was benchmarked against a variety of single and dual-processor Athlon and Pentium 4-based PCs in two key content creation applications, Adobe Premiere 6.5 and Lightwave 7.5. Among the systems tested is a dual Athlon MP 2200+, a dual 2.4 GHz Pentium 4 Xeon, a 3.06 GHz Pentium 4 (with and without HyperThreading enabled), and an Athlon XP 2800+. There is also quick overview of the architectural details of the G4+ relative to the Athlon and Pentium 4, as well as some thoughts on the future with the IBM PowerPC 970.

The Hitchhiker's Guide to the Mainframe
Ace Hardware brings us: The Hitchhiker's Guide to the Mainframe.
"I will not attempt to cover the architecture in any technical detail at this time; the intent is simply to set the stage for future articles. If you are in fact an experienced mainframe user then this article probably has no particular value for you, other than possible amusement. I will assume that the reader is familiar with general computer concepts and technologies, and will present the information in terms that should be familiar to PC or Unix geeks."

Computers for Albatrosses
O'Reilly tells us about building a datalogger to track Albatrosses.
"When David said he needed a datalogger, immediately visions of HC11-based computers, with separate RAM and ROM, danced in my head. He said that he wanted it small. No problem, I thought. HC11 computers are small, ranging in size from a playing card to a paperback novel, depending on the application. "I want to put it on a bird," he said. "You want to what?" I replied."

Lightweight FTP Jail with NAT
Daemon News talks about building a lightweight FTP jail with NAT.
"We will do this by installing an FTP daemon in a jailed environment. The jail(8) command lets you create a virtual machine, so to speak, inside a host. This virtual machine is severely limited in the ways it can interact with the host. For most purposes, it's nothing more than an isolated machine that can talk to the host only via IP networking."

A Linux High-Res Network Camera
Linux Devices tells us about a Linux based reconfigurable high-res network camera.
"It was not difficult to find a good FPGA candidate. The latest member of Xilinx's low-cost Spartan IIe FPGA family -- a 300K gates XC2S300E chip (see note below, for an update). Plus, they have free ISE Webpack development software available for download that worked fine for the design and was able to make use of 98% of the chip's resources."

Review of the Sun Blade 150
Sun introduced the Blades workstations more than a year ago, but we haven't really seen any reviews on these machines and many people are wondering about them. OSNews got their hands on the highest-end Blade 150 model and they give it a run for its money. In short, CDE performs acceptably, but Gnome2 seems to be slow on these machines.

Python Persistence Management
In this article will give you a general understanding of various persistence mechanisms for Python objects, from relational databases to Python pickles. It explains persistence, Python's object serialization capabilities, the basics of pickling, advanced issues that arise when you start to pickle complex objects, and ways to anticipate and plan around common problems due to changes in your class definitions.

Slackware Linux
Unix Review takes a look at Slackware.
"Slackware's installer is pretty basic and doesn't do all the hardware detection that other distros do now, so you'll need to manually set up your sound card and printer. However, Slack does attempt to autodetect your network card so that you don't need to worry about knowing exactly which kernel module the NIC will need. So far, I haven't found a Linux-compatible network card that Slackware couldn't detect."

Linux GUI Development for Windows Programmers
Moving from windows to linux development you are confronted with a myriad of options. QT vs GTK+? Which language should I use c/c++/java/perl/tcl/python/ruby or javascript? Should I use a commercial/proprietary layout/rad tool (QT or Kylix) or an open source one? What about Mozilla? My background was primarily in programming Visual Basic and Lotus Notes. Where should I start?

Interview With Ingo Molnar
KernelTrap has interviewed Ingo Molnar who has been contributing to Linux kernel development since 1995 with an impressive list of accomplishments. Most recently his O(1) scheduler was merged into the 2.5 development kernel, as well as much work to enhance the handling of threads. Other highly visible contributions include software-RAID support and the in-kernel Tux web and FTP servers.

In this interview, Ingo explores how he started working on the Linux kernel, noting, "It might sound a bit strange but i installed my first Linux box for the sole purpose of looking at the kernel source." He goes on to explain the concepts behind his new O(1) scheduler, and to describe many of his other kernel efforts. The interview was conducted over several months, and covers a wide range interesting topics...

Terra Soft Presents PPC Hardware Solution
OSNews features an exclusive article revealing a new product from Terra Soft, makers of the most popular PPC Linux distribution, Yellow Dog Linux, which effectively enables YDL and Linux to run on its own platform. Terra Soft are offering a motherboard and a complete PC based on the 600 Mhz G3 (G4 is also planned). This is of course still PPC, but it ain't a Mac. However, the article hints that it might be technically possible to run MacOS9 and OSX via Mac-On-Linux.
