On the Web
The theme of our November 2002 issue was internationalization, and we were fortunate to receive quite a few interesting articles on the subject. One story in particular, Wayne Marshall's “Radio E-Mail in West Africa”, gave insight into how much we can accomplish when we are willing to shift our perspectives a bit and work with the tools available—in Wayne's case, HF radios capable of long ranges but little bandwidth. Unfortunately, space constraints in our print edition forced us to cut some of the details of the e-mail configuration used from the article. The long version, however, is available on our web site at www.linuxjournal.com/article/6299. If you're interested in the details of how Wayne's radio e-mail project came about or how the setup differs for incoming as opposed to outgoing mail, be sure to read “Radio E-Mail in West Africa: the Complete Version”. And be sure to check out the readers' comments at the end; a lot of people are sharing their unique communication setups.
On the topic of internationalization, Fred Noronha has been providing us with Linux and open-source news from India and neighboring countries. The grassroots support for software libre is strong, and even the government has expressed interest in moving their systems to open source. But are they serious? In a follow-up web article, “Indian Government's Reported Move Makes News, Then Fuels Skepticism” (www.linuxjournal.com/article/6389), Fred reports that many speculate the Indian government is simply using free software as a threat to get Microsoft to lower license fees or make a local investment. As one reader states, India cannot rely on the government to lead the Free Software movement. “So we the people will adopt free software and eventually the government will have no choice but [to] follow the people.”
Finally, we're certainly not opposed to stirring up some trouble; we just don't always know where it's going to come from. So quite innocently we announced the winners of the 2002 Readers' Choice Awards on our web site in mid-November in the form of a press release (www.linuxjournal.com/article/6380). We certainly weren't expecting the amount of reader comments we received—42 comments, to be exact, as I write this. So who comments on a press release? People who agree on one thing: our voters/readers are idiots because they didn't choose the correct winners. Some days it feels like we are all back in the sandbox, ready to hit each other on the head with our toy trucks if we don't get our way. So jump on to the article's web page and throw some sand yourself.

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
