Did you folks get my e-mail from out Humanitarian Support Operations Conference? The Center for Excellence in Disaster Management and Humanitarian Assistance's Humanitarian Support Operations Conference was held recently at the Ilikai Hotel in Waikiki. The event drew over 170 people from 23 Asian-Pacific countries including Thailand, China, South Korea, New Zealand, Papua New Guinea, Fiji, Mongolia, Australia, the Philippines, Indonesia and many others.
Supporting the conference was a pair of Linux machines providing Internet access (WWW and Mail) running NCSA's Mosaic and the COE's Conference Home page. Attendee photos were digitized and put online using an Apple QuickTake camera. Events included a working session and introduction to Linux, which was a first experience for many of these countries.
Future COE plans include travelling to these countries with Linux laptops, as we've chosen to use the OS as our Internet connectivity platform used with developing nations. In short, choosing Linux gives us a cost-free method of connecting dozens of dissimilar host sites with a similar operating environment. We'll begin building custom database applications, namely a front end for our Oracle SQL server (Sparc 20 based) for Linux by the first week of October.
We're very excited about Linux, and everyone at the conference was equally enthusiastic about seeing the “Linux Work-Servers” and the power they give to otherwise blah-entrenched x86s. One of the delegates from India asked me if his 486-100 would be suited for such a project...I had to laugh when I told him that the machine he was using was a 486-33! (We had 20 inch monitors on the desk and the boxes underneath...so it looked like we had some real powerstations going!)
If you'd like additional information about what our future plans for Linux hold, please don't hesitate to ask.
In case you hadn't gotten this, I enclose the following reply sent to Keith Briggs. In his letter, Mr. Briggs called to my attention my apparent invention of a university:
Dear Mr Wilder:
I quote from Linux Journal #17, page 22: “...comes from the Australian Technical University in Melbourne,...” I am sorry to have to inform you that there is no such place in Melbourne. There is not even a place with a similar name! (The Australian National University comes closest, but it is in Canberra).
Dear Keith Briggs,
I don't know how I came up with the “Australian Technical University in Melbourne”; every reference I can locate in the materials I prepared the review from points to the University of Technology, Sydney. My apologies to all.

I read your review of my book (Teach Yourself Perl in 21 Days, reviewed by David Flood on page 15 —ED) in the November 1995 Linux Journal. In the review, David noted that he was unable to get an errata sheet from CompuServe. In case you have not yet managed to pick up an errata list anywhere, I have taken the liberty of enclosing one. This contains every error I know of.
Thank you for taking the time to review my book. If you know of anyone else who wants an errata sheet, let me know and I will pass this on to them.
I am glad that you have found my book useful, and of course encourage you to tell everyone you know to buy it.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
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
