What is Java?

I was more than surprised to see the October cover of Linux Journal. What exactly was the idea behind putting the map of Indonesia and Indonesia Sea on it?

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.bernardo@visus.alce.pt

Dear Sir,

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.

More Graphics Standards

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

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
