Mystery lock up.
We covered HP's new Linux laptop at LinuxWorld in August 2004, and they loaned us one for a full review that fall. The nx5000 is a mid-size business notebook PC with a base weight of 5.75 pounds and a base price of $1,199. Display choices are XGA (1024×768) or SXGA+ (1400×1050), for an additional $75. Our review unit had the 1400×1050 screen and a combo DVD/CD-RW drive and weighed in at 2.85kg, or 6.28lb. The processor was a 1.4GHz Intel Pentium M. The nx5000 comes with 256MB to 2GB of memory, and ours had 512MB. A subset of SuSE 9.1 Professional is preinstalled and two CDs are included.
Physical layout is thoughtful, with a good-size keyboard. As on many laptops, the Ctrl keys are undersized and squeezed into the corner of the bottom row with a bunch of other modifiers. For regular use, you'll want to swap Caps Lock and Ctrl. The Escape key is undersized but in a convenient place above the tilde, and the backslash/pipe key is big and where it belongs, above Enter.
Overall size is larger than lightness-crazed road-warrior types will be comfortable with, but if you're transporting it only for commuting or occasional trips, the extra size and weight could be a good trade-off for you.
HP claims a full working day of battery life with both batteries installed, but laptop battery life is a notorious “your mileage may vary” measurement. Under light use with wireless on, including some text editing, Web surfing, listening to Internet radio and uploading the photo for this article, the nx5000 with one battery lasted more than 4.5 hours. HP installs Thomas Renninger's powersave dæmon, which is a nice touch.
The Atheros a/b/g card was not configured out of the box, but a quick point-and-click session to set it to DHCP brought it up on an 802.11b network. The installed Atheros driver is proprietary. There's one other proprietary module installed, the slamr module for Winmodem support.
Laptop audio is usually tinny and awful, but the nx5000's speakers, branded with a JBL Pro logo, are consumer audio quality and plenty good enough for Internet radio, playing games or watching a DVD. If you use the nx5000 as your home entertainment system too, the weight starts to look not so bad. Speaking of watching DVDs, the included DVD-playing software is InterVideo's LinDVD, which is DVD CCA-licensed. Playback was smooth, even with tasks running in the background. For day-to-day use, it might be more practical to swap out the DVD drive for the extra battery, use an independently developed DVD player that lets you play movies from the hard drive and simply connect an external drive when needed.
The volume controls for the speakers and headphones work separately, and the KDE volume control is configured to control speaker volume only. We had to go to the YaST volume settings control panel to turn up the headphones. This is a little confusing to start with, but the right thing for those times when you want to listen in private and not annoy everyone else in the library or café when you forget to plug in the headphones and an instant message comes in. A little user-interface help is needed here.
Everything onboard works, but how well is the system configured to work with the external USB devices that are your eyes and ears on the road?
We plugged in a brand-new Canon PowerShot S410 camera and fired up the preinstalled Digikam to pull the photos off with no configuration needed.
Plugging in a Sony DCR-HC20 MiniDV camcorder meant a little command-line work. The IEEE 1394 modules were installed, and following the instructions in Marcel's column in the December 2004 issue, we modprobed them in. Kino was not installed, but we brought in a copy from a SuSE 9.1 Professional DVD and captured some video.
It's understandable that a nonlinear video editing tool is missing from a default laptop install, but also strangely missing was OpenSSH, which people at Linux Journal use constantly. We pulled that in from the SuSE DVD as well. If you invest in this laptop, you also might want to pick up a copy of the full distribution so that you can get your favorite tools just as easily.
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
