The Ultimate Linux Laptop
So, what does the word ultimate mean in the context of Linux-based laptop computers? Should it be the laptop to blow away all others? Or might the best model be more subtle in its “ultimateness”? Given that we use our laptops in such varied ways, the answer in this context is more elusive than on the desktop or in the server room.
Brainstorming for inspiration on the criteria for the Ultimate Laptop, and given that my laptop and I reside in Michigan, my mind wandered instinctively to cars. “Which vehicle would most people agree is ultimate?”, I pondered. Based on what I see on local streets, I suspect that the Escalade, Corvette or XLR Roadster would win bragging rights. But, that's Michigan. An informal poll of my California friends gave me arguments for several different BMWs, Lexuses (Lexi?), Mini Coopers, Mustangs and more. What is a poor Products Editor to do?
Later, after reviewing the several entries for the Ultimate Linux Laptop competition, the ultimate automotive metaphor finally came to me. Although I probably will be run out of auto country for saying this, the laptop that was most like the Toyota Prius was the winner. In other words, the top machine was the one that would get LJ's readers' heads nodding and saliva flowing with its novel and elegant—but not necessarily just brawny—Linux-based innovations.
Based on these criteria, the winner of the 2007 Ultimate Linux Laptop competition is the EmperorLinux Raven X60 Tablet. The Raven X60 is a portable, powerful, well-designed, Core 2 Duo machine with several unique innovations that Emperor has brought to the Linux space. Shortly, we'll delve into why we selected the Raven X60, but first, here's a little more about the competition itself.
For this first iteration of Ultimate Linux Laptop, we emphasized the innovation-focused “Prius effect” as mentioned above, considering the entire computing experience. We called on vendors to send us their best publicly available total package for around $3,000 US or less. Linux should be pre-installed, and all major features (such as Wi-Fi support, Bluetooth, function keys and so on) should work without major extra input from the user. Furthermore, after testing all the machines, we were more convinced that the complete package is much greater than the sum of its parts. Some machines looked wonderful on paper but simply failed to inspire. Factors such as ergonomic construction, service, documentation and attention to detail noticeably and considerably separated the best from the adequate.
We anticipate that some readers will prefer that the Ultimate Linux Laptop act more like a Porsche than a Prius and provide the most smoke-producing performance possible. Yes, we considered this, and in the future, we may bump up the price point to include exotic machines. This year, however, we felt that the current market for Linux laptops warranted a brains-over-brawn approach.
Luckily, many of the firms that ship pre-installed Linux machines took part in our competition. We cheered the news of Dell's shipping pre-installed Linux laptops and tried to get our hands on one for testing. Unfortunately, however, Dell expressed zero interest in participating, despite repeated calls around Round Rock. In contrast, I spoke with either the CEOs or Vice Presidents of all of the Linux specialist providers. Although many in our community make calls to support Dell, I say that actions speak louder than words. In my experience, our community-based providers generally do an excellent job of supporting what they sell.
Now, on to the Raven X60 Tablet laptop!
Here are the specs for the Raven X60 Tablet we tested, priced at $2,950 US:
Dual-boot Ubuntu Feisty Fawn (kernel 2.6.21) and Fedora Core 6 (kernel 2.6.17), both 32-bit.
Processor: Intel 1,667MHz Core 2 Duo L2400 with 2,048KB cache (667MHz FSB).
2,048MB of RAM.
100GB hard disk at 5,400RPM.
DVD+/-RW (in UltraBase, included).
12.1" LCD display at 1400x1050.
Networking: 10/100/1000Mbps Ethernet, 56Kbps modem, 802.11a/b/g (54Mbps) Wi-Fi, Bluetooth (2Mbps).
Weight: 3.4 lbs. alone, 4.4 lbs. with battery, 6.4 lbs. with UltraBase.
Battery: 8-cell, 4.5 amp hours.
Ports: two USB, one CardBus, one RJ-45, one VGA, one secure digital.
Wacom Tablet integrated into LCD display.
Biometric fingerprint scanner.
UltraBase station includes DVD+/-RW, additional ports—parallel, serial, USB (four), PS/2—and pass-through of RJ-45, VGA.
Four features on the Raven X60 Tablet put it all alone into this year's winner's circle. First, the X60, which is simply a Linux-powered Lenovo ThinkPad X60 Tablet, is a well-built ergonomically efficient machine. Lenovo has continued IBM's strong tradition of quality, which is evident in the components used, the construction (such as the display swivel) and the comfortable computing experience (for example, the keyboard and stylus response).
The second stand-out feature is the 4,096dpi Wacom Tablet built in to the LCD display, which works like a charm. Emperor conveniently pre-installs the Jarnal handwriting recognition software with a desktop icon, so you can rotate and flip the display any way you wish, even flat on its back, and start writing. The Dynamic X rotation allows you to cycle between four screen orientations without restarting X. In addition, the included stylus can act as a mouse or a stylus with a pressure-sensitive eraser. Besides tinkering with Jarnal, I had a blast playing with the tablet function on The GIMP, which made me feel like a budding artist. Emperor's president, Lincoln Durey, told me that The GIMP “takes advantage of the 256 levels of pressure sensitivity that the stylus provides”.
Yet another slick feature is the Raven X60's biometric fingerprint scanner, which currently works on the GDM, login and sudo PAM services. Once you've trained your own fingerprints, you can use it to log in or simply revert to your password.
The fourth feature to distinguish this machine is its comprehensive, well-designed manual, which is specific to the Raven X60. It's obvious that Emperor considers good documentation a core part of the user's experience, as the manual nicely predicts what information the user will seek. Furthermore, each section clearly explains not only what features exist and how to use them, but also what features are not working yet. This service will save you hours by steering you away from dead ends.

Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
