Linux 2.6 and Hyper-Threading
2cpu tells us about Linux 2.6 and Hyper-Threading.
"While the general concensus on Prescott's performance in its current state (namely clockspeed) has not been glowing, we should take a moment to go over the architectural changes meant to improve hyper-threading. The simplest change Intel made to Prescott was increasing the size of the respective L caches on the processor. The L1 data cache was bumped from 8KB to 16KB and the L2 from 512KB to 1024KB. As I discussed previously, when you have two logical processors competing for shared resources, more is better."

Trusted Solaris
NWfusion tells us about Trusted Solaris.
"But other security features won't be moved into Solaris. For example, Trusted Solaris lets users label all the applications and files on a server and then restrict access to those items based on an employee's security clearance level. Such features carry too much performance or administrative overhead to be made a part of the general purpose OS, Iyer said."

Getting Reacquainted with dbXML 2.0
XML.com tells us about dbXML 2.0.
"The dbXML project has an interesting history. Some have compared it to a soap opera. Though there has been quite a bit of flux in the project, its goal has been to produce a high quality, small footprint XML database that just works."

ALT Linux Compact
Virtualsky reviews ALT Linux Compact 2.3.
"Compact has been designed with the PC builder (or OEM) in mind. However, I've found Compact to be simple enough for just about anyone to install and use. If you can rip songs from a CD into MP3s and burn them back to a CD, you should be able to install Compact 2.3 without any difficulties."

Home Automation with Mac OS X, Part 2
MacDevCenter brings us Home Automation with Mac OS X, Part 2. (While the article was written for a Mac most of the information could be used with Linux or any other OS - Noel)
"The X10 technology is surprisingly elegant and simple in its design and execution. Every module has a house code (A-P) and an individual unit code (1-16). By assigning each module a specific house code and unit code, you are able to designate which module will respond to which signal. These signals travel over your home's existing wiring, so you don't need to retrofit your house."

Deep inside the K Desktop Environment 3.2
Ars Technica reviews the K Desktop Environment 3.2.
"JuK is KDE's new music player with a focus on managing huge playlists. It started as a tool for managing the meta tags of music files, which is apparent in the excellent integration of the optionally-visible tag editor below the track list. A search bar offers quick access to particular songs. JuK usually resides in the system tray where it takes up the least possible space."

Creating a PPP dialup server with OpenBSD
The OpenBSD Journal tells us how to create a PPP dialup server with OpenBSD.
"So, this is all you need to do if you want dialup on the cheap. It has proven to be ultra-reliable for me. You can dial in with a terminal or a PPP client this way. You could even do SLIP through a scripted login (SLIP doesn't have anything like LCP or PAP to automate the process) or UUCP transfers. Wow, what a throw-back to last century :) ..."

Building Task Packages
UserLinux talks about building Task Packages.
"Task" packages are packages that do not install any software of their own, but depend upon a list of packages that you'd need for a particular "task". For example, operating a desktop, or a server. Installing the task package causes all of the packages it depends upon to be installed. You don't need to be a programmer to generate them. You really only need to know how to use the shell and edit some text files."

Novell is Becoming a True Linux Player
IT Managers Journal talks about how Novell is becoming a true Linux player.
"Acquiring SUSE allows Novell to be significantly more competitive in the Linux market. It will also allow Novell to penetrate different sub-segments of the market since SUSE has specific expertise in Linux for mainframes and in Linux for the desktop. Compare this with Red Hat, whose core strength is in enterprise computing, i.e., Linux-on-Intel servers running corporate applications and data center infrastructure. While Novell will still offer customers the choice to implement its proprietary NetWare operating system, its focus has clearly shifted toward the Linux market."

A Security Primer for Mac OS X
MacDevCenter brings us A Security Primer for Mac OS X.
"Unfortunately, some Mac users forget that security is more than just applying the occasional patch. It is a continuously evolving quest that requires additional steps to make their systems more secure. Luckily, the Unix foundation of Mac OS X, Darwin, has provided us with powerful tools that we can leverage to help our computers remain secure in an otherwise dangerous world."

X Marks the Spot: Looking back at X11 Developments
For the past year, there has been a slow and steady stream of news events regarding XFree86, X11, or new X server implementations. To those not paying close attention (and even those who are), the meaning of some of these events may not be clear. In this brief article, Oscar Boykin attempts to share his impression on what the changes mean for users of free software on the desktop. It appears that XFree86 is in some turmoil, and it may leave some to infer that free desktop systems will suffer.

Ethernet Electric Razors
Light Reading tells us that soon we may be able to use use Ethernet to run our electric razor.
"That's the kind of thing Cisco Systems Inc. (Nasdaq: CSCO - message board) and others see happening with the advent of Power over Ethernet (POE), a topic that's been long discussed but didn't become universal until last June, when the Institute of Electrical and Electronics Engineers Inc. (IEEE) ratified the 802.3af standard "

Kernel Trouble

Using the 2.6 Kernel with Your Current System
Linux Devices talks about how to use a 2.6 Kernel with our current system.
"If you are creating a system that can boot and run both 2.4 and 2.6-based kernels, and your Linux vendor does not provide updated and flexible startup and shutdown scripts, conditionalizing your startup scripts based on the version of the kernel that is booting is an excellent solution. The easiest way to do this is to set an environment variable based on the identity of the running kernel, as in the following example: ..."
