When I wrote the article appearing in issue 169 of the Linux Journal we had only had George (that's what we named our Chumby) for a couple weeks. We've had him for a couple months now, and George has become well integrated into our family. Things have settled down from the initial excitement we all had when he arrived and now it almost seems like he's always been there, sitting in his corner of the kitchen, there when you need him, and quietly waiting when you don't. That's not to say our relationship has not had some bumps along the way.

Learn how to extend the Eclipse Modeling Framework Ecore metamodel by adding elements to reusable Java snippets. Discover, step by step, how to use dynamic templates with JET to generate the implementation code for the extended model elements.

MySQL owners past and present opened the annual user's conference to re-assure them Sun Microsystems has no hidden agenda for the open source database. Sun chief executive Jonathan Schwartz and software executive vice president Rich Green pledged it's not just business as usual for MySQL - they'll also commit Sun's engineering resources, sales and global support.

JWChat is a Jabber instant messaging client that is written using only HTML and JavaScript. This means that you need not install a Jabber instant messaging client in order to use Jabber, assuming you already have a Web browser installed. A Jabber client that runs in a Web browser could be just the ticket for such uses as providing instant messaging to visitors to your Web site.

Not a Linux article, but on a topic near and dear to our hearts -- An attack by an IP holding company. In this case, Monster Cable's lawyers sending a Cease and Desist letter to Blue Jeans Cable. Too often, FOSS folk, bless their hearts, panic at the word "patent". This letter from Blue Jeans President and former litigator, Kurt Denke, gives some idea why real companies -- companies with valuable businesses and assets to protect don't just go out and routinely drop "patent bombs".

Fonality is building an IP-PBX company that leverages Asterisk and embraces managed service providers. In other words, Fonality has converged three hot markets (unified communications, open source and managed services) into a single solution. And a new Fonality product release could help the company strengthen its international presence. Here are the details from MSPmentor.

The open-source Eclipse Foundation announced four initiatives that address embedded and mobile device development. The new Device Software Development Project (DSDP) initiatives include a framework for communications among debugging and monitoring devices, and a Texas Instruments (TI)-sponsored project devoted to creating and configuring C/C++ tools for "highly constrained" devices.

Everyone grumbles about Linux driver problems, but kernel hacker Greg Kroah-Hartman actually did something about it. Kroah-Hartman created a program by which open-source developers would create drivers for hardware vendors even if their equipment was proprietary. Over a year later, though, Kroah-Hartman has found that the vast majority of hardware OEMs (original equipment manufacturers) already offer Linux support.

This is the second in our series co-publishing with Fedora Interviews. In Fedora, the supported method for upgrading from one release to the next is by downloading the media and rebooting from the media and using Anaconda. Why was this the case, and what's wrong with a yum upgrade?

This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I will also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

When looking at the AMD Phenom 9500 under Linux, we had found this processor had posed a number of issues from kernel panics to other troubles when running Ubuntu 7.10 with the Linux 2.6.22 kernel. Once, however, upgrading to Ubuntu 8.04 with the Linux 2.6.24 kernel these problems had vanished and we were pleased by this native quad-core desktop processor from AMD. Released a month prior to the first Phenom desktop CPUs were the quad-core Opteron 2300 "Barcelona" processors. We hadn't looked at any AMD Barcelona processors at that time, but today we finally have our hands on two of the new AMD Opteron 2356 server/workstation processors.

You may recall about 4 months ago, I reviewed the Eee PC. As it turned out, the computer was actually a gift from my wife, so unlike many of the other products I review, I got to keep it. I'm going to give you the quick rundown of how those 4 months have been with the little lappy at my side:

Free operating systems differ from the proprietary variety in a number of ways. One of the differences which is most evident to all users is in the provision of device drivers. With free systems, device drivers are free software, provided with the system itself. Proprietary systems tend to provide relatively few drivers; instead, proprietary drivers are shipped with the hardware itself and installed separately. Anybody who wonders about which model works better would be well advised to look at the events of March 28, when Creative Labs shut down an outside developer who had been working to improve Creative's drivers.

Ever want to boot up your Ubuntu Linux system really quick to look something up? Sure, I think we all do that from time to time. Hate it when you get the forced file system check because you’ve booted up 30 times? I do. Imagine how I felt in front of a room full of young students, who were attending a small business seminar when this “lengthy” check kept us waiting, while listening to them snigger and giggle. (”Windows doesn’t do this”, “…that’s a cheap OS…”, “Get a real OS”, “…hurry up man…”, “…slooooowwwww…”, “…Linux sucks…”, and so on).

Linux does everything that many users want it to, but some people have tasks that require Windows applications. You can dual-boot both operating systems, or run Windows in a virtualized environment on Linux. Alas, virtualization makes the guest OS almost useless for processor- and RAM-intensive tasks like editing videos and playing games. Now, a Ubuntu-based distro called andLinux takes cooperation with Windows to a whole new level.

I recently ran into trouble trying to play copy-protected DVDs on my new installation of Kubuntu 8.04 (Hardy Heron beta). Initially it seemed that there was a problem with the installation of libdvdcss2, because Kaffeine kept offering to re-install it. However, after a re-start of Kaffeine from Konsole with wizard mode (kaffeine -w), I got this error...

The Debian GNU / Linux distribution has announced the eighth and final update to the Debian 3.1 Sarge release. Time sure does fly. It seems like just yesterday that I was complaining about the delayed Sarge release (it was actually 2004), and wondering what impact the upstart Ubuntu distribution would have on Debian.

Via Technologies has laid out a new initiative to improve support for the open source development community. The chip maker will launch an official Via Linux website this month as a first step in the programme.

In about 100 days, the United States Federal Government will be required to be running large portions of their systems on IPv6. Now, for the few non-technical in the crowd, it means that the address your PC uses to connect to the Internet, in most cases, is IPv4.

UNIX, Novell, Red Hat and Ubuntu Linux were the most reliable server operating systems. Linux distributions experienced 1-2 hours per server per annum downtime, an average decrease of 75% since 2006. Surprisingly, downtime increased by 25% to nearly 9 hours per server, per year for Windows Server 2003.
