What is Java?
My national patriotism is very hurt by putting Dili on the map with no reference whatsoever to East Timor. Dili IS NOT INDONESIA! Dili is an indivisible part of East Timor, and by the United Nations Resolution, Portugal is still the rightful administrative power of East Timor. The Indonesian government has shown no regard for the human rights, and refuses the right of self-determination of the people of East Timor. —Daniel Bernardodaniel.email@example.com
Let me congratulate you and your team for all the work you have done to benefit the Linux Community. The October issue of LJ was once more a good example of what a magazine should be—both instructive and entertaining.
Although your introduction to the Java world was quite good, I was a bit disappointed you didn't refer to the wonderful relationship between the Java world and the Linux world. An interview with Randy Chapman would maybe be in order. Perhaps focusing on Sun's license restrictions and (dare I say it?) aggressive position towards the Linux Community would also not be a bad idea. Maybe for a future Java II issue?
Finally, I would just like to point out a geographical error in your cover: the city of Dili, as well as half the island it is on (East Timor), is not a part of Indonesia. In the eyes of the UN, it is still a Portuguese colony. It was invaded in 1974 by Indonesia, and its people (the Maubere) are still fighting for their freedom. I know it's not your duty to know this, but you'll also understand it is mine to report it.
Keep up the good work! —Filipe Custódiofmc@novabase.pt
Just a couple of weeks after receiving your letters, in a strange coincidence, the Nobel Committee jointly awarded East Timor's Roman Catholic Bishop Carlos Filipe Ximenes Belo and exiled resistance leader Jose Ramos-Horta the 1996 Nobel Peace Prize for their efforts in the 21-year-old conflict with Indonesia.
The prize draws international attention to the situation and awards US$1.12 million to the recipients, which Committee Chairman Francis Sejersted said was for “their work toward a just and peaceful solution to the conflict in East Timor.”
In 1975, shortly after Portugal pulled out of what had been a Portuguese colony, the Indonesian government moved in and annexed East Timor a year later, an action which the United Nations has never recognized.
But Linux Journal is not a magazine about world politics, so I leave further investigation to the interested readers; a web search I did suggests there is ample reading material available.
In the November 1996 issue (#31), Jorg-Rudiger Hill wrote an article entitled “Linux Goes 3D: An Introduction to Mesa/OpenGL”. In the article, he writes, “OpenGL is the standard for 3D computer graphics and is managed by the Architecture Review Board.” Then, on page 27, this text is enlarged and quoted in a box.
I would like to point out there are other standards for 3-D graphics besides OpenGL. A visit to the ANSI web site (www.ansi.org) reveals two. First, the Graphical Kernel System (GKS) is a graphics standard which now has 3-D extensions (ANSI X3.124-1985). Second, the Programmer's Hierarchical Interactive Graphics System (PHIGS) is a newer standard (ANSI/ISO 9592-1-1989) with many features OpenGL lacks. You may have also heard of PEX, PHIGS Extensions to X, which supports networked 3-D graphics.
These are just some thoughts for you to consider. —John F. Bunchbuncho@ro.com

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
