Linux in a Nutshell released in third, updated edition

(Josette Garcia, O'Reilly & Associates, Inc.)

O'Reilly's latest edition in the popular "In a Nutshell" series, Linux in a Nutshell, 3rd Edition covers all the core commands available on common Linux distributions. "Linux is changing rapidly, and so are the needs of its users," says Andy Oram, O'Reilly Linux Editor. "Among the most significant features of this new edition are the in-depth tutorials on each of the three graphical interfaces that confront users when they boot Linux-KDE, GNOME, and the older, but highly stable fvwm. But that's not all. Anyone who wants to upgrade software uses a package manager. Our new Nutshell edition expands the discussion of the Red Hat Package Manager (RPM) and includes a new section on the Debian Package Manager (DPKG). It's bound to be one of the most important Linux titles published this year."

A must-have book for any Linux user, Linux in a Nutshell, 3rd Edition isn't a scaled-down quick reference of common commands, but a complete reference to all user, programming, administration, and networking commands.

"Since the last edition of the book came out, Linux has made great strides in providing the kind of user-friendly environment with the kind of tools that users have come to expect from a windowing system," says co-author Ellen Siever. "The desktop environments have made life easier for users who don't necessarily want to learn obscure Unix commands and who want a friendlier environment. Improvements in package management tools have simplified the installation and upgrading of software. We've also added much more coverage of networking commands." In addition, the book also covers a wide range of GNU tools for Unix users who have GNU versions of standard Unix tools.

Linux in a Nutshell, 3rd Edition is a must for any Linux user; it weighs less than a stack of manual pages, but delivers everything needed for common, day-to-day use.


DARPA Researchers Work to Speed Up Internet

(Staff Sgt. Kathleen T. Rhem, USA American Forces Press Service)

(EXCERPT) WASHINGTON, Aug. 30, 2000 -- DoD researchers are working to make Internet connections 1,000 times faster than they are today, which will open up amazing new possibilities for using the Internet.

"Today's Internet does amazing things," said Mari Maeda, project officer for the Defense Advanced Research Projects Agency. "But compared to what it could do, it's really only the tip of the iceberg.

"The Internet has changed the way we live, the way we shop," she continued. "Once we have this new technology in place, and as the Internet evolves, we will be able to do all sorts of new things that are just outside the realm of our imagination today."

Maeda said performance and speed are the main limitations to today's Internet. A person using a high-speed corporate network might download Web pages at speeds of millions of bits per second, but a home user might get only one-tenth or one-hundredth of that speed, she said.

"What we are trying to do is increase that speed by 1,000 times. That will enable you to do tremendous things," she said. For instance, Maeda explained, today's Internet allows users to download digital photographs, but the Internet of the future would allow doctors to share x-ray images, which require much higher resolution, in real time.

She said such an advanced new Internet would have "all sorts of applications" in crisis management, the medical and entertainment professions, and the military. The new Internet would also allow more people to use it at one time, Maeda added.

DARPA researchers are currently working on prototypes of new software and hardware that would enable this high-speed network. They are also working on a test of the new system. Maeda said the test, called "SuperNet" and in its third year, links two or three dozen sites.

"This is not a replacement for the Internet," she said. "It's a network-growth experiment so that researchers can basically field, test and experiment with their new software and hardware and try them out."

Applications for the military might include high-definition radar images seen in real time, more advanced meteorological radar images, and less expensive, high- quality teleconferencing.

DARPA, located in Arlington, Va., is spending $30 million per year over the next five years to get the system up and going. Maeda said continued funding is necessary if the United States wants to stay at the forefront of Internet technology.

"We are basically harvesting a lot of research that we have done in the past three to six years. All of the research that DARPA and other agencies have funded in the past is starting to pay off now," she said. "Unless we continue to fund research and continue to do far-looking research, the world is going to dry up. The U.S. is right now No. 1 in this area, and the U.S. cannot maintain that superiority unless we continue to fund research."

Maeda said the military would likely be the first to benefit from this research, followed by corporate America. She foresees private users upgrading from modems to cable digital subscriber lines over the next several years, and said their 1,000-times-faster Internet service is five to 10 years away.

But DARPA researchers aren't limiting their vision to 10 years in the future. They're even looking at how we'll be able to send the Internet to space, she said.

"One of the farthest-term research projects we are funding is interplanetary Internet -- how we are going to actually extend this Internet to space, to the solar system," Maeda said. "It's not something that is going to happen in the next three to four years, but it's something we need to start thinking about. It will definitely be a real issue in the next 20 years."
