Editorial Product Review: :A modern computer system that's not part of a network is even more of an anomaly today than it was when we published the first edition of this book in 1991. But however widespread networks have become, managing a network and getting it to perform well can still be a problem. 'Managing NFS and NIS,' in a new edition based on Solaris 8, is a guide to two tools that are absolutely essential to distributed computing environments: the Network Filesystem (NFS) and the Network Information System (formerly called the ...
Editorial Product Review: :When 'Practical Unix Security' was first published more than a decade ago, it became an instant classic. Crammed with information about host security, it saved many a Unix system administrator from disaster. The second edition added much-needed Internet security coverage and doubled the size of the original volume. The third edition is a comprehensive update of this very popular book - a companion for the Unix/Linux system administrator who needs to secure his or her organization's system, networks, and web presence in an increasingly hostile world. Focusing on the ...
Editorial Product Review: :Rich Text Format, or RTF, is the internal markup language used by Microsoft Word and understood by dozens of other word processors. RTF is a universal file format that pervades practically every desktop. Because RTF is text, it's much easier to generate and process than binary .doc files. Any programmer working with word processing documents needs to learn enough RTF to get around, whether it's to format text for Word (or almost any other word processor), to make global changes to an existing document, or to convert Word files ...
Editorial Product Review: :If you are a network administrator, you're under a lot of pressure to ensure that mission-critical systems are completely safe from malicious code, buffer overflows, stealth port scans, SMB probes, OS fingerprinting attempts, CGI attacks, and other network intruders. Designing a reliable way to detect intruders before they get in is an essential--but often overwhelming--challenge. Snort, the defacto open source standard of intrusion detection tools, is capable of performing real-time traffic analysis and packet logging on IP network. It can perform protocol analysis, content searching, and matching. Snort can ...
Editorial Product Review: :What's 'real-world programming'? Real-world programming (typically called real-time programming) is programming that interacts in some way with the 'real world' of daily life. At one time, real-time systems were confined to very esoteric applications, like rocket guidance systems. Now, they play a role in almost every aspect of life: they control the brakes on your car, video games, automatic bank tellers -- and the disk drive in your computer. It won't be long before mundane devices like toasters and hair dryers have microprocessors built in, to say nothing of ...
Editorial Product Review: :IRC (Internet Relay Chat) may very well turn out to be the world's most successful hack. In 1988, Jarkko Oikarinen wrote the original IRC program at the University of Oulu, Finland. As he says in his foreword, 'IRC started as one summer trainee's programming exercise. A hack grew into a software development project that hundreds of people participated in, and then became a worldwide environment where tens of thousands of people now spend time with each other. I have found many of my friends through IRC and learnt a ...
Editorial Product Review: :The beauty of open source is making code freely available. The curse is trying to organize the chaos that code development can evolve into. CVS, the Concurrent Version System, is an open source tool for managing and distributing source code. It allows multiple users dispersed over a wide geographic area to work on the same file at the same time, using a shared directory. Under CVS, multiple users can check out files from a directory tree, make changes, and then commit those changes back into the directory. CVS is ...
Editorial Product Review: :Redundant Array of Independent Disks (RAID) technology is becoming a standard feature of computer systems that support mission-critical services like file sharing, mail exchange, or Web servers. RAID offers two benefits to these essential systems: improved I/O performance and fail-safe data storage. Although bandwidth problems on networks are well documented, the internal data transfer bottleneck that exists at the hardware level in each system can also leave you with perplexing performance issues. RAID is a cost-effective and easy-to-manage way to alleviate this bandwidth problem by distributing the I/O load ...
Editorial Product Review: :This guide, intended as an explanation of the POSIX standard and as a reference for the POSIX.1 programming library, helps you write more portable programs. Most UNIX systems today are POSIX compliant because the federal government requires it for its purchases. Even OSF and UI agree on support for POSIX. Unfortunately, given the manufacturer's documentation, it can be difficult to distinguish system-specific features from those features defined by POSIX. The POSIX Programmer's Guide is especially helpful if you are writing programs that must run on multiple UNIX platforms. This ...
On paper, the Mio DigiWalker P550 looks to be an attractive gadget for the mobile professional, combining the capabilities of a PDA and GPS into one device. However, its poor battery life and subpar navigation skills tell a different story.
Though it won't appeal to the masses quite yet, the Nokia N800 Internet Tablet is a nice, portable device for on-the-go Web browsing, and it has some worthy upgrades.
Diesel vehicles have nearly a 50-percent market share in Europe, thanks to tax incentives and diesel-friendly legislation across the EU. Diesels are so passé there that you can buy a BMW 730d and no one will think it odd that your luxury car burns oil. Pull up in a diesel 7-Series in America and people would leer at you like you've alighted from an amphibious vehicle reeking of saltwater and dead trout.
But now, thanks to the oft-reported combo of newly-raised CAFE standards, not-so-newly-raised gas prices, and the 50-state diesel engine, GM, Ford, and Chrysler are about to dip more than a hesitant toe into the diesel game. Chrysler offers a diesel in the Grand Cherokee, but soon all three automakers will offer diesels in their best-selling lineups of light trucks -- the Dodge Ram 1500 is expected to offer a 50-state diesel after 2009. Light trucks are being used to lead the charge since those buyers stand to gain the most with the least amount of (perceived) sacrifice.
Diesels currently have 3.2-percent of the American market. Some estimates put them at 15-percent by 2015. That's a huge leap, and diesel still has plenty of hurdles. Diesels will come with a cost premium over gasoline-engined cars. That should be easy enough to conquer -- incentives and some quick cost and longevity calculations should convince people of the benefit. The real hurdle is the nagging issue of perception. The plan will probably be to attack that with a price that makes the proposition unbeatable. Said Chrysler's director of environmental affairs, "If it's priced right, we can sell diesel here. Diesel can give you an immediate poke in fuel economy -- 20 to 40 percent. Not many technologies can deliver that today."
