Linux and Politics at CES
While the big cheeses of the consumer electronics industry make obeisance to Big Hollywood over the issue of customer control of PCs and entertainment devices, the mood at the Consumer Electronics show seems to call out for a move the other way, toward badly-needed reform for the controversial Digital Millennium Copyright Act (DMCA). The Home Recording Rights Coalition (HRRC) was out in the lobby to support Virginia Rep. Rick Boucher's Digital Media Consumers' Rights Act, which would reform the DMCA to allow circumvention of copy-restriction schemes for purposes other than copyright infringement.
In the four-year history of the DMCA, the anti-circumvention provision of the law has been used only against developers of new technology, never against actual copyright infringers.
Also at CES, Sharp showed off the (almost) only-in-Japan Zaurus SL-C700, which is shaped like a miniature "Tablet PC" with a screen that pivots from PDA-style to open above a small keyboard. The screen is a full 640x480, twice the size of the one on the popular SL-5500.
While attendees couldn't touch, or in most cases read the exquisitely rendered but Japanese text on, the new model, hands-on demos of the US SL-5500 were well-attended.
"One advantage of Linux is that many of the downloadable applications are available under the GPL license, which means that they are completely free," said a cheerful presenter to a row of attendees during a demo. That's free as freedom, if you want to be picky, but attendees got the point.
Third-party Zaurus hardware and software vendors included Socket, the company behind the top-rated 802.11b card for the Zaurus in our January issue.
The Pegasos MicroATX motherboard sports all the usual PC motherboard features, with one small difference -- it's PowerPC based. Samuel Rydh of the Mac-on-Linux Project pointed out that the board is compatible with a wide variety of PC-market PCI cards, and can also support Mac-on-Linux to allow for a complete MacOS session within a Linux one.
Mac-on-Linux works similarly to VMWare on the Intel architecture, but isn't as tricky because the PowerPC is much friendlier to virtualization. The Pegasos board is priced at $470 for a single PowerPC G3 version.
Last year, at least four vendors brought Linux-based PDAs. Royal, which had been set to go with a Microwindows-based offering, went back to the drawing board and came back this year with a new prototype, the LineaLX, based on a Motorola MX1 at 200MHz. It's running Linux, but neither the Qtopia, like the Zaurus, or Microwindows, like last year. We'll be bugging them for a look at how to develop for this thing. At a show dominated by cellular and WiFi, the notable hardware feature of the LineaLX is a built-in 56kpbs modem, with full-sized RJ-11 jack.
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
