On October 29th the NLUUG held their second conference this year (the first, held in the spring, focused on file systems). With over 200 visitors and talks by 19 speakers, all prominent in their respective fields, this conference was of particularly high quality. This is surely emphasized by the location and surroundings and the excellent organization. Read on for a short impression on the conference, which was attended by several KDE community members.

Mobile specialist Palm strengthens its team by hiring Matthew Tippett, the Linux graphic driver developer since 2003 at ATI, to be in charge of Linux kernel development.

Developer Nanni Bassetti has announced the release of version 1.0 of the Computer Aided INvestigative Environment (CAINE) Linux live distribution. CAINE and NetBookCAINE (NBCAINE) provide a complete digital forensic environment that's organised to integrate existing software tools as software modules and to provide a simple graphical user interface (GUI).

Keeping any computer system running can be some work. It would be nice if we never had to do any type of maintenance or troubleshooting, but no operating system has reached that point. Many desktop Linux users have server administration experience and are quite comfortable dropping to the command line and tinkering with their system. Not only do they know how to do this, it is the method that makes them comfortable. For those users who use a desktop operating system and expect a graphical experience, opening a terminal window is not a normal thing to do. That does not mean they are incapable of learning it. They are just more comfortable with a visual interface. There are many control panel tools and settings dialogs in KDE that make it easier for graphical-minded users to get things done. Here are five stand-alone applications that will help you stay informed about your computer’s status and health.

A couple weeks ago I wrote about NoSQL and provided a short overview of the landscape of non-relational databases. One that has become increasingly popular is Apache CouchDB, so I’d like to spend a couple weeks digging into it a bit and talking about why it’s so interesting. Before I do, it’s worth noting that Ubuntu 9.10 was just released and uses CouchDB under the hood. The Ubuntu One backup/synchronization service makes it easy to back up and sync Firefox bookmarks, Tomboy notes, files, contacts, and more. As more users adopt 9.10 and Ubuntu One, CouchDB usage grows accordingly. If you read my previous NoSQL article and wondered which projects are ready for prime time, consider this a big vote of confidence for CouchDB.

In like a lion, out like a Snow Leopard? Apple changed its spots on Sun's ZFS fairly quickly. This week the company shutterd the ZFS Project on Mac OS Forge, and there's no hide or hair of ZFS to be found in Snow Leopard. It's a pretty quick turnabout from a few years ago, when Sun CEO Jonathan Schwartz was touting Apple's inclusion of ZFS in Leopard.

The Gimp is a powerful graphical application that can handle just about any kind of bit-mapped editing job. You can re-touch photos, shrink or enlarge pictures, combine elements using layers, and many other operations with little to moderate effort. The program also has a bunch of interesting “filters” that transform your picture into something new. Perhaps you need to make a cool text logo for your company or are a teacher needing to create some coloring projects, for your kids. The Gimp has you covered in those departments. And, once you try using a few of the filters, I'm sure you'll see opportunities to "filter" pictures, all over the place.

There are far too many interesting Linux and free software conferences these days, so it would be difficult—really, impossible—to attend them all. Slides and videos of the talks can help fill in the gaps, but, for conferences with a more academic bent, the papers that are the basis of the presentations can give an even more detailed look. The papers from the recently concluded Real Time Linux Workshop are a good example; this article will briefly look at a few of them.

Android 2.0, nicknamed "Eclair," will make its big entrance on the Droid next month, and other handsets are sure to follow. Version 2.0 brings a set of new features to the table, including native support for Microsoft Exchange. However, the wide-open Android ecosystem may be prone to fragmentation as the underlying platform grows in strength and ability.

According to a report in the French language publication 01net, the French General Directorate of Public Finance (DGFiP) is switching to Mozilla's Thunderbird email client for 130,000 users. The switch is happening as part of a merger of two French tax authorities which had different email systems, The Directorate General Tax (DGI) which used Lotus Notes and the Directorate General of Public Accountancy (DGCP) which used Microsoft Outlook.

Freescale Semiconductor has begun taking orders for a Power Architecture development platform for Android-based products, opening a new category of embedded devices to Google's open-source mobile operating system.

A Qt developer has brought a piece of KDE to Maemo. After plasmoids, this week brings the Plasma desktop. Also a KDE Maemo mailing list.

An open memo from the U.S. DoD declares that open source software is no worse than traditional software, perhaps even useful.

The mobile phone market suffered a six percent drop in shipments year to year, but saw a 5.6 percent improvement over the previous quarter, says IDC. Meanwhile, Motorola, which showed a 6.4 percent yearly drop, according to IDC, posted 3Q earnings that beat analyst predictions.

In response to the news this week that the city of Los Angeles is going Googlefied with a $7.25 million, five-year deal to adopt Gmail, Google Calendar and other applications, Novell's blog has an interesting rebuttal. Of course, the reason for the city's switch to Google's corner of the cloud is to save money that it would otherwise spend on expensive software licenses, and it will save. Still, the Novell blog post is intriguing because it's a missive from an open source-focused company criticizing the Los Angeles decision with barbs frequently aimed at open source solutions. It claims that L.A. should have opted for Novell's fee-based Groupwise solution. Huh?

When running a modern Linux graphics driver stack in a composited environment there is a lot less tearing -- particularly with regard to video playback, but OpenGL applications too -- now than there was in the past, but there is still room for improvement. One of the ways to improve this is by properly controlling the display of buffers with how often the swaps occur and to sync them with the monitor's refresh rate or the rate at which the compositor is running.

If you're fetching several resultsets that contain a lot of common data, it can make sense to obtain a single resultset that has all the data that's required, store it in a temporary table, and then select from this temporary table as needed.

The Linux-Kongress is traditionally where kernel developers exchange honors and advice about new features and enhancements. This year a number of speakers presented performance improvement data and discussed what aspects of Linux can be drawn out even more.

While recent Ubuntu releases have been more about careful enhancement and distribution maintenance, the current version 9.10 offers a new look as well as a whole range of new technical features – the developers have restructured the distribution's standard filesystem, boot system and hardware maintenance, and they have introduced new software. Not everything is completely new; many changes were introduced into Ubuntu as part of a gradual development process and have now reached the maturity required for general use.
