By now, every Linux user's heard of KDE 4.0, and the controversy surrounding its release. Here's one partisan KDE user's take on it — with screenshots.
openSUSE is a popular German Linux distribution that Distrowatch.com lists as one of the "top ten." Version 10.3 was released on October 4th. Underneath its new green artwork, the new version's improvements include cutting down the time it takes to reach the graphical login screen; speeding up and streamlining its package management utility; and making it easier for users to install software using a new "one-click install" process. There's a lot to like here.
The last Kanotix release (based on Debian Sid) came out in October, 2006. Shortly thereafter, a Kanotix co-developer (and many of Kanotix's other developers) left the project, mainly due to a disagreement over whether Kanotix should be based on Sid (Debian's unstable branch) or something less volatile, like Etch (Debian's current stable branch) or Ubuntu. Kanotix's founder now has a new, Etch-based version of Kanotix in development, code-named "Thorhammer."
Unless you're able to deal with such esoteric problems as diagnosing a buggy post-install script, or figuring out how to deal with a major change in the directory structure of X.org, you might occasionally find running a Debian Sid-based system to be more than you can handle. And that's where Sidux comes in. Sidux's goal is to allow mere mortals the ability to run Debian Sid on the desktop, in order to take advantage of the latest Debian software available. Its development team helps guide its users through the occasional bumps in Sid, via IRC and its user forum. Another goal is to offer a consistent release cycle. Sidux comes with a variety of "convenience scripts" and utilities you won't find in Debian proper, that make it easier to do such things as administer your system and install proprietary software.
Slackware is the oldest surviving Linux distribution; its first version came out in 1993. Version 12 was recently released. As its Wikipedia entry notes, it's got a reputation for sacrificing ease-of-use (in terms of configuration and package management tools provided by the distribution) in favor of letting the end user configure the system and its software by herself.
Part 2 of the Fedora 7 "Moonshine" review.
I was anxious to test the new Linux Mint release in hopes that wireless might be working, but alas, I spent the better part of 4 days downloading in vain.
PCLinuxOS is an up-and-coming distribution that recently made it into Distrowatch.com's list of Top Ten Distributions. I installed PCLinuxOS Test 4 on a 10 GB partition (with a separate 1 GB /home partition) on an AMD Athlon 2600+ with 640 MB of RAM and an NVIDIA GeForce 6200 LE graphics card. This hardware is no great shakes nowadays, but it's plenty fast enough to run PCLinuxOS with all the bells and whistles.
Linux Mint is an Ubuntu-based distro whose goal in life, per its website, "is to produce an elegant, up to date and comfortable GNU/Linux desktop distribution." The developers have released both GNOME-based and KDE-based versions in the past, and their latest version, v2.2 "Bianca," is already final in its GNOME incarnation.
