On desktops and Netbooks, Ubuntu has had a remarkable year. But on the server, Ubuntu continues to face multiple major challenges, reports The VAR Guy. Here's the scoop.

The 32nd edition of the Top 500 supercomputers lists was released late last week and Linux-based systems occupy 439 of the 500 positions. Other Unix variants, including BSD-based systems occupy another 24 positions.

A recent attack piece against Richard Stallman was written by Linus Torvalds on the eve of Obama’s election. Black and white by Linus Torvalds Linus begins with this: So I’m pretty well-known for not exactly being a huge fan of the FSF and Richard Stallman, despite the fact that I obviously love the GPLv2 and use it as the license for all my projects that I care about. How unfortunate to write negatively of Stallman in the very first sentence. Read the full story at Freesoftware Magazine.

PHP is an easy-to-learn programming language. It's well suited for developing simple scripts you can use to help you in all kinds of games. Each article in this series will cover 10 scripts simple enough for even a beginning developer, but useful enough for a seasoned game player.

The Linux desktop comes with a variety of multimedia players, such as Xine, MPlayer, and Amarok. Yet all digital media players are only as good as the files they have to work with, and preparing those files requires the best tag editor you can find. I checked out half a dozen of the more popular and stable graphical ID3 tag editors available for Linux. I found that going from no tags to great tags requires keeping more than one of these editors on hand.

In an effort to coax more users to take advantage of the many extensions for its Firefox browser, Mozilla has just launched FashionYourFirefox.com. The site is divided up into categories, which cater to individual interests and "online lifestyles," according to Mozilla's announcement. The site looks like a good idea for extension novices, but I don't see some of my favorite extensions, and some of the categories have a pretty sparse number of extensions.

Let cron handle your repetitive tasks - an introduction to crontab. A crontab is a simple text file that holds a list of commands that are to be run at specified times. These commands, and their related run times, are controlled by the cron daemon and are executed in the system's background. More information can be found by viewing the crontab man page. We will run through a simple crontab example later.

If all goes according to plan, the first alpha release for Ubuntu 9.04 (the Jaunty Jackalope) will be released tomorrow. It's not even been one month since the release of Ubuntu 8.10, but this first alpha release will show early signs of what we can expect to see in this next Canonical-sponsored release -- albeit many of the features are still in planning. In this article we will provide a glimpse at what Ubuntu 9.04 should hold in store to captivate Linux desktop users.

A patent represents a grant from the United States government to an individual for the exclusive right to make, use, import, sell, and offer to sell an invention. In order to obtain a patent, an inventor must prove that the invention is new, useful, and not merely an obvious improvement over what was already known.

ono Bacon, Ubuntu's community manager, has been hard at work nailing gelatin to the wall. Okay, not literally, but he's putting a lot of thought into how he can best determine the vitality, growth, needs and wants of the Ubuntu community and how they best mesh with, and give back to, the wider Linux and open source communities.

With diff-ext, GNOME users can compare and merge files from within Nautilus. If, instead, you use KDE 3, try out kdiff-ext from the same site, which works with Konqueror. Each utility handles paths to files and directories and invokes an external diff tool to perform the grunt work. With diff-ext you can easily compare two files with different names, from different directories, or whole directory trees.

Chip maker ARM is to get Ubuntu Linux up and running on its ARMv7 processor architcture, part of its plan to get its chips into netbooks and handheld internet devices. It's all about taking the fight to Intel's Atom, of course. The chip giant's processor has become the de facto standard for small, cheap computers. But the handheld tablet side of the story - the MID - has yet to take off, providing ARM with an opportunity to tout its platform's superior power efficiency.

Doing “stuff” on linux is just so easy. By “stuff”, I mean everything from doing some normal day chores, downloading files, customizing things, automating routine tasks, etc. The backbone for this is “the terminal” (not the movie :P). I can do almost anything I want from the console.

Linux and other Unix-like operating systems use the term “swap” to describe both the act of moving memory pages between RAM and disk, and the region of a disk the pages are stored on. It is common to use a whole partition of a hard disk for swapping. However, with the 2.6 Linux kernel, swap files are just as fast as swap partitions. Now, many admins (both Windows and Linux/UNIX) follow an old rule of thumb that your swap partition should be twice the size of your main system RAM. Let us say I’ve 32GB RAM, should I set swap space to 64 GB? Is 64 GB of swap space really required? How big should your Linux / UNIX swap space be?

Security is based on three characteristics: prevention, protection and detection. Grsecurity is a patch for the Linux kernel that allows you to increase each of these points. This howto was performed on a Debian Lenny system. Thus some tools are Debian specific. However, tasks can be performed with other distro specific tools or even with universal tools (make).

Hi All, Here's my 6th tip in the "OpenLDAP Quick Tips" series: "You want to encrypt the passwords that are stored in your directory server":..

These may not cover every base, but they probably cover at least one base that you don't see covered much ;) Today's going to be a "fun with awk" day. I figure we should have one now because we never had them in school when I was a kid... The topic, as the title suggests, has to do with columnar arithmetic or, less pompously put, performing arithmetic operations on columns or, even more accessibly, adding stuff up ;) It's somewhat like our older post on doing simple cumulative math with awk, but slightly more confusing.

To great fanfare, Microsoft has announced that it is deploying XO laptops in Quetame and Chia, Colombia, with the Windows XP operations system, what I like to call "Windows XO", thereby claiming that Colombia signs up for OLPC laptops with Windows. This bragging certainly has pissed off Greg Dek, a Red Hat Community Architect working on OLPC. Greg declares that Microsoft bought 10,000 XO laptops in May and can do with them whatever they want, including trumpeted up pilots of Windows XO, and that OLPC builds with Linux and Sugar, and always will.

Last week I talked a bit about the bipolar world of printing on Linux: the best of times, the worst of times; the easiest and the hardest; the most reliable and the most annoying. I raised a number of questions such as why do print jobs disappear without a trace, then reappear days later? Printing multiple copies, if you had hit the print button in frustration multiple times. Is this printer really online and working? Does it have enough toner and paper? If there is a problem, why won't it tell me in a reasonable way? Why isn't there an obvious, easy button for "cancel the print job plz, kthx"?

The iPhone and iPod Touch haven taken the mobile market by storm. Apple's AppStore is full of interesting applications that take advantage of the two devices's capabilities. But what's in there for Linux users? Sadly, GTKPod and Amarok cannot yet transfer files on an iPhone with the 2.x firmware upgrade, but there are other interesting ways your iPhone can interact with your Linux desktop and even servers.
