Itty-bitty, teeny-weeny Linux PCs

  • Story Type: News Story; Groups: Linux
Over at our sister site LinuxDevices, we're always looking at small, embedded-Linux systems. While reviewing Freespire recently on a Mini koobox, an Apple Mini-sized system, I began to wonder, Just how small do full-featured, Linux-powered PCs come?

Command "ipcs -m" appears to be almost useless for getting Oracle 11g shared memory allocation maps. The basic steps for shared memory monitoring and tuning /dev/shm to handle instances with MEMORY_TARGET more then 1024M had been explained in Tanel Poder’s blog. Posting bellow follows advices from Tanel Poder’s blog to build Oracle 11g (64 bit) ASM database with MEMORY_TARGET size 1.2 GB on CentOS 5.

Make Your Linux Desktop Look Like A Mac - Mac4Lin Project Documentation

Do you want to give your desktop a dash of Mac OS X? The goal of this project is to bring the look and feel of Mac OS X (latest being 10.5, Leopard) to *nix GTK based systems. This document will present the procedure to install Mac4Lin pack & tweak certain things to get that almost perfect Mac OS X like desktop.

Tidy up your filesystem with FSlint

Over time, a filesystem accumulates a lot of useless items. FSlint is a nifty little tool that helps you clean your filesystem by pointing out junk in the form of empty directories, corrupt symlinks, files with bad names, duplicate and temp files, and more. However, its usefulness is marred by a virtually total lack of documentation and a GUI that takes some getting used to.

Open Source ERP: Today's Hottest Emerging Technology?

What's the most exciting technology of the next few years for the enterprise? Forget folding displays and virtual worlds: Think open source ERP, say some pioneering information technology leaders.

What really should be a major focus for fedora developers

"This is one of the things which I feel is really hurting Linux... the inability to properly upgrade a distribution. Fedora and Ubuntu both have a 6 month time frame with releases, thats two versions a year. One would think that they would make upgrading as flawless as possible."

One Laptop per Child gets first order

Uruguay has placed an order for 100,000 of the laptops aimed at children in the developing world, the first firm order received by the organisation.

Is Microsoft Hijacking Open Source?

Like many, I was pretty shocked by the recent Microsoft-EU deal to settle the long-running investigation into interoperability issues. This was not so much because of the way Microsoft has used every kind of delaying tactic it could before eventually agreeing (for the nth time) to try harder in the future. My real dismay was provoked by the gap between appearance and reality – a chasm that I think bodes ill for the future of open source.

Wired Magazine “Doesn’t Get It”

This month’s issue of Wired Magazine had an article in it about LaLa, a CD swapping service. In the article, Wired’s Cliff Kuang wrote “The arrangement exploits a loophole in copyright law: While distributing duplicates is verboten, it’s perfectly legal to trade your own property.”

Linux: HowTo: Emergency Reboot a Remote Machine

Sometimes the machine you're working on has a little oops. Maybe the reboot command has hung and the system will not shutdown or a kernel panic has occurred and although you still have shell access, there is little more you can do with the machine. The solution is simple: you need to hard reboot the machine. But you're in Phoenix and the machine is in L.A. Like any good system administrator, you have the machine hooked up to an IP-KVM (or serial over IP, if the machine is headless), but the magic SysRq keys won't send properly. So what's a sysadmin to do?

Gaming from within the terminal

MUDs (Multi-User Dungeons) are text-driven cooperative or competitive games that you can play either straight from your terminal using the Telnet protocol or through a separate application specially designed to play MUDs. The majority of MUDs are free to play. Here's how you can get started with them. To find a MUD that appeals to you, visit a MUD-list such as The Mud Connector or Mud Magic. Both have reviews and top-rated and "game of the month" features to help you find a MUD to jump into. I recommend Mud Magic for beginners, as it is easier to navigate and provides clear, comprehensive lists of top-10 MUDs.

Review of Linux Distributions - Part 2

Last week I wrote the first part of this series which discussed the installation of Mepis, Kubuntu, OpenSuse, and Freespire on my laptops. Now that I have had time to play with each of the operating systems I would like to discuss my impressions of the different distributions. I have not spent any time on OpenSuse yet so I will leave it out of the discussion.

Ars at FOSSCamp: revolutionizing the command line with Hotwire

Colin Walters of Red Hat chaired a FOSSCamp session about Hotwire, a unique and innovative graphical shell environment designed to improve the command-line user experience. I've been testing Hotwire releases for some time now, so the opportunity to see Walters present his invention in person seemed too good to pass up.

Linux-powered PMP sports 7-inch touchscreen

iRiver is readying a Linux-based media recorder/player comprised of a detachable mobile unit and tethered docking station. The Unit2's base station offers a DVD/CD player, TV tuner, and PC-style I/O, while the detachable display features a 7-inch WVGA (800x480) touchscreen, WiFi, and USB. Apparently, the idea is to use the docking station to record DVDs, music CDs, or TV content onto the portable unit, which can then be carried with the user.

Fedora 8 Werewolf

The release of Fedora 8 (codenamed Werewolf) is due out for release in less than two weeks and comes with a host of new features. Fedora 8 will offer a Codec Buddy for installing audio/video codecs, an open-source Java stack now based upon IcedTea, improved laptop support, the Pulse Audio sound server, remote virtualization support, and much more. As a sneak peak at the final release of Fedora 8, taken from the Fedora 2007-10-24 Rawhide spin we have screenshots of the improvements to the Fedora Firstboot, the Fedora 8 GNOME desktop, and also the KDE version of Fedora 8. Enjoy!

GIMP tricks: Liquid rescaling by example

Have you ever taken a picture which would be just great only if you could remove that strange unwanted object that showed up in the middle of nowhere and now kills the whole effect? Or perhaps you just want to get rid of your ex-girlfriend and keep the photo with a fantastic landscape alone? Whatever your secret plans are, GIMP Liquid rescale plugin is there for you. Just use it!

Making Linux application user interfaces richer with OpenGL

Ars was at FOSSCamp this weekend. Think of FOSSCamp as an "un-conference" without a set agenda where the minds behind open source projects get together and plot world domination (and, err, ways to improve their code). One fascinating session (and one that shows how FOSSCamp works and why it's so productive) was given by Mirco Müller, who discussed using OpenGL in GTK applications. Müller—the developer behind Cairo-Clock and the LowFat image viewer—talked about the state of OpenGL support in desktop applications and described various techniques that developers can use to make OpenGL content integrate better with conventional GTK user interfaces.

The Linux Community of Interest

Back in 1995, I read an article about the scarcity of webmasters and switched my specialty. I often look for hot spots and retool to meet the needs. Before 1995, Oracle Financials was hot. I just didn’t care much for the rigidity of technology. But, I was an accountant and an IT guy so I had tooled up for database programming.read more
