The new PC-BSD 1.4 beta, released last week, offers 3-D desktop support via Beryl as well as late-model components such as KDE 3.5.7, FreeBSD 6.2, Xorg 7.2, a selection of fresh GUI tools and utilities, and a variety of optional components, as detailed in the full release notes.

It strives for user-friendliness primarily via a graphical installation program and a KDE graphical interface.

This is Canonical's first native Ubuntu system deployment and management tool.

Lars Ellenberg started an effort to getDRBD, the Distributed Replicated Block Service merged into the Linux kernel. When asked for clarification as to what it was, Lars explained,"think of it as RAID1 over TCP. Typically you have one Node in Primary, the other as Secondary, replication target only. But you can also have both Active, for use with a cluster file system." Earlier in the thread he described it as"a stacked block device driver".

A number of KDE related news stories are floating about the interweb today, so here's a quick round-up. Aaron Seigo writes his KDE e.V. Presidential Address on his blog. Over at Ars Technica, I have an article talking about the future of KHTML and Webkit. Daniel Molkentin has published a new book on coding for Qt 4.x and lastly, I've stumbled across a short visual tutorial for those Mac OS X users among us that are looking to help test the KDE/Mac snapshots.

Find out about the Eclipse Platform, including its origin and architecture. Starting with a brief discussion about the open source nature of Eclipse and its support for multiple programming languages, we demonstrate the Java development environment with a simple programming example.

This follow-up to David Gallardo's "Getting started with the Eclipse Platform" offers new information relevant for Eclipse V3.3.

Following the progress of founder and chief maintainer Barry Kauler's Puppy Linux is like watching a litter of scampering frisky pups. A fast gestating two months after the prior release, newborn Puppy Linux Version 2.17 -- aka "Dancer" -- was pushed out late last week. Version 2.17 of Puppy Linux -- so named to reflect its small, cuddly, yet very complete persona -- popped out at a mere 82.6MB, says the distro's website.

Navicore is Nokia's GPS mapping and navigation program for the Linux-powered N800 Internet Tablet. The kit comes with a Bluetooth GPS receiver, car-mounting hardware, and a memory card containing the Navicore Personal software and map collection. If you have an N800, it's a great travel aid. Sadly, there is one strike against Navicore that I see no way around for desktop Linux users. The N800 Navigation Kit ships with a memory card containing one region's maps (say, North America). The Navicore Web site contains additional maps for other regions of the world -- but you cannot access or install any of that data without running Windows.

Some would argue this story doesn't belong on a Linux News Site. I may tend to agree with you. The value isn't what you will personally gain from this article...it's who you can pass it on to. We all know one person who might want to take a peek...

When a partition that was previously an ext3 partition is converted to disk dump, the next time the system will boot, it will show a "Token is too" error. This problem occurs and leaves the system in an unbootable state. This is because yaboot tries to to boot from a partition of type “Linux” (Type 83). This error does not occur if the partition is labeled as swap (Type 82).

Learning a new language cannot be complete without a few 'real world' examples. 'Hello world!'s and fibonacci sequences are always nice as an introduction to certain aspects of programming, but soon or later you crave something meatier to chew on. 'Ruby by Example: Concepts and Code' by Kevin C. Baird provides a wealth of knowledge via general to specialized examples of the dynamic object oriented programming language, Ruby. Want to build and mp3 playlist processor? How about parse out secret codes from 'Moby Dick'? Read on!

Zend pitches PHP to the enterprise. PHP is wildly popular in the open source community, but less so in the enterprise. These things are hard to measure, but one indicator is job vacancies.
