Laptops for Linux!
Each laptop partitioned its drive differently, and the Attache even includes a tiny DOS partition for the emulator, but included neither the correct file-system module for the new kernel nor an entry in fstab or mtab. I think both laptops have a slightly odd partition setup, with too much swap (256MB on the Attache, 128MB on the AS-LT300). Table 3 is a short file-system table so you can see how they're set up for Linux, a bit systematic for what is presumably a single-user system.
It is difficult to put together a top-quality laptop for Linux. There are too many peculiarities and quirks of the hardware, and drivers are hard to come by. The best anyone can hope for in the near future is that everything will work after a bit of fixing. I would expect LinuxLaptops to lead the way, with ASL and the others adopting those ideas which turn out well. We don't have Linux-specific laptop factories, and we don't have perfect support for all the hardware. Laptops for Linux are coming, and hopefully some day they will be as completely functional as desktop boxes. Right now, they lack audio and some video support (svgalib, for example). These laptops do have PCMCIA slots, infrared ports, disk and CD-ROM (optional DVD) drives, and some potential for expansion. Check the web sites for the full technical details.
Now that players have entered the Linux laptop market, we're going to see quality go up and price go down, though there are many options to buying a Linux laptop. If you need just a portable machine with little computing power, you could get an inexpensive or used laptop and install Linux. If you want the flat screen monitor, you could buy one (I think they are worth the reduced eye strain and radiation); Xi Graphics already has some drivers available. If you want a small computer, pair your flat panel display with a NetWinder and Happy Hacking Keyboard Lite. If you need a laptop but don't like either of these, you could try one of LinuxLaptops' other models (the Paquet looks exceedingly cute). Also, you could wait until we move on to 64-bit RISC technology (one x86 is enough, eh?). If you are buying only one computer, and you live in an apartment which you'd like to look nice (i.e., no ugly CRTs), or if you travel and need your computer, these laptops have much to offer. The choice between our review subjects should be easy. By now, you must know if you're a Red Hat (AS-LT300) person or a Debian (Attache) person, although realistically, LinuxLaptops has made a more highly tuned machine for the price. Either way, how can you go wrong putting Linux on a computer, especially one as cool as a laptop?
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
