Among the commands: 1. Show ( and purge) installed but unused linux headers, image, or modules 2. Download all images from a site 3. Play high-res video files on a slow processor 4. Find the 20 biggest directories on the current filesystem etc.

I decided to put up this guide which shows how to install the latest Wine release in Ubuntu 9.04 using 3 different methods. The default Jaunty repositories come with Wine 1.0.1, but the latest release is 1.1.24 and a new version is available every two weeks, so here is a tutorial which explains how to get the last Wine release in Ubuntu or Kubuntu Jaunty.

We're on the verge of a serious evolution on the web. Right now, the common way to include video on the web is by use of Flash, a closed-source technology that is a massive resource hog. The answer is the HTML5 video tag, which allows you to embed video into HTML pages without the use of Flash or any other non-HTML technology; combined with open video codecs, this could provide the perfect opportunity to further open up and standardise the web.

Bring me a Pre that fixes Synergy, improves performance, has iPhone-like materials/build quality, full search, full copy/paste, visual voicemail and a more mature app store and I’ll leave Apple. Until then, personally, I’ll keep a close eye on the Pre because Palm totally gets it. This is what a smartphone is supposed to be and we finally, two years after the iPhone’s release, have a real competitor both in hardware and in OS.

Clutter, the open-source toolkit designed to develop rich user interfaces with OpenGL and OpenGL ES but without the complexity of programming to such APIs, is nearing version 1.0. This toolkit, which was used to create the very impressive Moblin V2 interface, is backed by Intel and continues to gain steam. Version 0.9.4 was released just this morning, which is serving as the Clutter 1.0.0 Release Candidate 1 build.

I can talk until I'm blue in my space about the technical advantages of Linux and open-source software. Forget about that for now though. Let me give you a reason for your office to use them that may strike home: It can save jobs, including, just maybe, your job. This simple fact was brought home to me over the weekend when I was at the SouthEast Linux Fest at Clemson University. There, I saw Chad Wollenberg, a network administrator who focuses on the integration of free and open technologies in education. The point of his talk was really quite simple: "Why should our school systems be paying for proprietary software when teachers are being laid off?"

The Linux Plumbers Conference 2009 is now accepting proposal submissions. Proposals can be edited and created until Monday 22 June 2009 PDT (7 AM Tuesday June 22 2009 GMT). Submissions are invited for speakers in our microconference tracks as well as the general track session.

A home-cooked Microsoft license has carved out a small but growing following among the open-source community in less than two years. Microsoft's Public License (MS-PL) is used by 1.03 per cent of open-source projects less than two-years after it was officially recognized by the Open-Source Initiative and is poised to overtake the Mozilla Public License (MPL) in terms of popularity.

In part one we wrote a basic bare bones port check program, in this part of the series we take the next step and fixup a few issues plus begin breaking out the code. This small program is a decent introduction (but definitely not definitive) to network programming.

Yet another beta! Changes in 1.8.1 Fixed bug in 1.8.0 which defaulted to "nl" (Dutch) instead of "us" during boot (Live CD). Changes in a nutshell (1.8.0): + Updated kernel 2.6.28 * New module powernow-nx + Updated Firefox. + Default keymap for Dutch is now "US". + LiveUSB with options toram and myconfig=usb works now. + Nautilus script TextEdit: Yes/No Buttons instead of Cancel/OK. + Grub background now available for isolinux CD. + Infamous "i810" and "trident" bug in Xorg fixed. + CPU frequency scaling should work now with Intel (Centrino/Speedstep/...) too. + Added firmware for Broadcom 43xx wireless chips.

The OpenSource World conference — previously known as LinuxWorld — is fast approaching &mdsah; it convenes in San Francisco from August 12 - 13, showcasing everything Open Source and more. Conference organizers this week drew back the curtain on one of the conference's main attractions, its keynote speakers, and the lineup promises to be an interesting listen.

Is it time to scrap Fedora? I've been in discussions with a group of other writers, Linux distribution watchers, Linux community leaders and developers in the past few days concerning Linux commercial vs. Linux community versions and some of us came to the conclusion that Fedora's relevance has waned. In fact, it might be time to scrap it completely. Or maybe it's time for Red Hat to step up and support it formally and unconditionally.

Apache (and other web servers) have some kind of DOS-able flaw. IIS does not have this flaw. Do "all computers" suffer from the problem? No - only Apache and other open source web servers. An example of the "when MSFT software has a problem, all computers are at risk" FUD, only in reverse.

As I wrote a few days ago, I replaced Kubuntu and Ubuntu on several of my home PCs with PCLinuxOS and 64 Studio. I was intending to wait a couple of months to post a followup because long-term performance is what matters. But a few things have impressed me so much these two newcomers to my little computing empire deserve an extra mention.

I've written quite a bit about using Linux to help educate people. In the past, I've discussed using Linux to teach astronomy, programming and computer logic design. So today, I'm writing about using the KDE Interactive Geometry (Kig) program to teach mathematics. Kig allows you to use various tools to diagram and demonstrate different mathematical concepts. With Kig, you can draw points, lines, line segments, half lines, vectors, circles and various other conic sections. When Kig refers to a “half line”, it means what I was taught was a ray—essentially a line with one endpoint. Drawing hyperbolic curves on the computer sure beats getting dry-erase marker all over yourself or sneezing because of chalk dust.

It's been a while since I had a look at Songbird, and that was when 1.0 came out. The new release was put out a little earlier this month and comes with a brand new equalizer, a new mode to auto-organise media files included in the collection and Last.fm radio integration. However, the most awaited feature is probably the 10-band equalizer and it is available using the Controls -> Equalizer menu option (or Ctrl+E). Here's how it looks:

With the release of Ubuntu 9.10, which is due out this October, Canonical and the Ubuntu developers hope to fix at least 100 "paper cuts" on the Ubuntu Linux desktop. Paper cuts are rather trivial usability bugs that are small, but in one way or another could impair the Linux desktop or increase the burden placed on a new Linux user ever so slightly.

One thing that I love about Linux (and Ubuntu) is that it is fully customizable and I can configure it to the way that I want it. Previously, I have already illustrated its flexibility by showing how you can transform Ubuntu Hardy and Intrepid into Mac OS X. Today, let’s bring a step further and see how we can transform Kubuntu Jaunty to Windows 7 in 3 simple steps.

SourceForge is keenly aware of its roots in the open source community, and its strategies for growth encompass ways to better serve its base. Among its goals are a transformation of the Sourceforge.net Web site into "a world-class development environment," said Jon Sobel, SourceForge's group president of media.

Qmailtoaster is a project that aims to make the installation of Qmail onto RPM based systems a snap. All of the packages are distributed in source RPMs so building the packages for your particular distro and architecture is as easy as running a script or a simple command for each package. The RPMs have all of the needed and commonly asked for patches included so you can have a mail server up and running in about an hour. When it's all complete, you'll have a full Qmail mail server installation ready for just about anything. I personally run Qmailtoaster servers for other companies and ISPs who have tens of thousands of users on their systems.
