I have just received the February 2003 issue of Linux Journal, was reading through the Letters and came across the one with the guy who wants to run Microsoft ads in LJ. If I want Microsoft ads, I will go to a Windows magazine. It is true that MS ads cannot harm us, but they are annoying!
Kudos for Jon Hall, the LJ magazine and the thought behind the GNU/Linux and other free, open-source software movements (“Back to Brazil”, Letters, February 2003). The heavy reluctance against land reform is the root cause of fundamental socioeconomic problems in many parts of the globe, including Southeast Asia, South Asia, Central and South America and Africa. I believe land reform movements in these countries share the same vein that the Linux/GNU movement has. Our country, Japan, had been coerced into doing a total land reform by the US occupation policy in 1940s. It liberated not only the land but the minds of so many common people, enabling the making of the world's second biggest economy and modern industry.
In two articles [LJ, September 2002], Doc Searls incorrectly claims that the terms “wardriving” and “warchalking” were derived from the movie War Games. I believe they actually were derived from the term “war dialing”, the process of sequentially dialing a range of phone numbers in search of a modem connect tone. War dialers were utilities that could be left to run and accumulate interesting numbers to be investigated later. These programs were the equivalent of today's internet port scanners.
War Games came out in 1983, and we don't know of an example of the term “wardialing” before that. Although the other “war” terms are derived from “wardialing”, it's likely that “wardialing” came from the movie. Wardialing is still a threat according to a 1998 survey by Peter Shipley: www.dis.org/filez/war.pdf.
Just to say what an inspirational answer to the unfair criticism maddog received from that reader in Brazil [Letters, LJ, February 2003]. I really liked maddog's reply, especially the paragraph that starts “I believe...”. I just might put that paragraph on an A4 page above my desk! Great stuff!
PS: Not sure what you guys have done, but LJ now arrives in my office in-tray the day after you announce it on the web site. It used to take weeks (or longer). Whatever you've done, keep doing it.
I don't subscribe to LJ to read about politics, especially apologies for terrorists and other assorted anti-American, third-world riffraff. My subscription expires in March 2004, and I won't be renewing.
I see Linux as losing its sense of humor. I am willing to bet a cup of coffee that this is due to the infusion of money from big business. Don't we have a wacky penguin? Don't we have XBill? Isn't that funny stuff? The answer is a qualified yes. It's funny, but it's funny in the same regard that recess is fun—that being because it is at a set time and place and supervised. But Linux never had a recess time before. You could play all day and still get everything done. It's time to get off our collective asses and put the fun back in Linux.
You can't spell FUN without U.
Before I decide not to resubscribe, is Linux Journal going to return to the size that it used to be? I feel that the quality and content of the magazine has dropped in the last year and find it hard to sign up again for another year. The cost has not changed, but the content has!
The number of pages of content depends on the number of pages of advertising. More ads fund more content. In a down economy when ads are few, page counts go down everywhere.
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
