February
Peter SalusYou're reading this on the Web. The Web is a teenage part of the Internet. And the Internet is the offspring of the ARPAnet, which turns 35 this year.
Do you know what the RFCs are? Have you read an RFC? There are about 3700 Requests For Comment as of early February 2004. But RFC 1 ("Host Software") was written by Steve Crocker, and dated Apr-07-1969. And the first RFC ("Network Timetable"), by Elmer Shapiro, was numbered 4, but dated "Mar-24-1969".
Cameron LairdFor quite a few UnixReview.com readers, Beginning PHP4 Databases will be the single most valuable book available on development of Web applications. Its flaws are likely to be only minor distractions to those out to learn more about the PHP programming language or Web-oriented database management. Here's the good and not-so-good about Beginning PHP4 Databases.
Joe "Zonker" BrockmeierZonker discusses using ccache to speed up compilations. He also touches on DVD burning.
Cameron LairdAssembly language can be high-level, too. That's what Randall Hyde promotes, and we think he's mostly right.
Ed SchaeferIn the introduction to his book, Automating Unix and Linux Administration, Kirk Bauer wants systems administrators to admit to being lazy. With his tongue planted firmly in his cheek, Bauer whimsically suggests that automating our work allows us to take "off to the lake". Even if you are not slothful or indolent, Bauer provides insight into tools that aren't yet part of the generic Unix core distribution.
Ed SchaeferThis month, Michael Wang shows us how to correctly create and remove lock files using his lock_unlock function.
Rajeev KumarEver wonder why those lines such as "default.ida?XXXXX...." or "cmd.exe" are in your Web server logs? If your Web server is running at the default port 80/tcp, it's likely that your Web server is being attacked by one of many Internet worms. Common worms, such as Code Red, send a text string like the following in the form of a URL (read as a single line):
Joe "Zonker" BrockmeierThis month, I have a couple of interesting tools you might want to add to your software toolbox. The first is Kuake, a console application with a twist. The second is XBindKeys, a program that you can use to create hotkey combinations to launch your most-often used applications and scripts in X.
Marcel GagnéVMware enables you to create virtual machines on your computer, complete with boot-up BIOS and memory checks. It virtualizes your hardware configuration, essentially creating a PC inside your PC. Guest operating systems such as Windows (9x, 2000, XP, etc), Linux (pretty much any flavor), Netware, and FreeBSD see these secure, virtualized machines as real systems complete with associated hardware (including USB). These guest operating systems are not emulated. They are actually running on your virtual machines. Furthermore, each virtual machine can be individually networked, allowing communication and file sharing between the virtual and the real machines.
Emmett DulaneyIn 2003, Novell — long known for their network operating system, NetWare — began betting heavily on Linux as they started the transition from a software company to a technology company. Among other lesser things that took place, they purchased the Ximian desktop and the SuSE version/flavor of the operating system (the latter deal was finalized in January).
Early on in the move to embrace Linux, Novell began plans for a new certification — Certified Linux Engineer (CLE). While not fully written in stone at the time that I pen this, many of the details surrounding what is planned for that certification have now become available. More will materialize when the exam goes live in the first quarter of this year.
A brief overview of what was then known about the CLE appeared in my November column. This month, I'll explore the certification and where it fits in with all the other Linux certifications that are available.
Joe CasadSince its founding, Red Hat has been locked in a never-ending quest to answer the question, "How do we make money on a product the customer can obtain elsewhere for free?" Enterprise Linux 3 is the latest episode in Red Hat's quest. And though you will find the same old Linux inside, this latest offering from the leading Linux vendor reflects a credible new approach to the market and a steady commitment to strategic engineering improvements. It looks like they might be on the right track, but only the market knows for sure.
Peter SalusIt's 35 years since UNIX was born, 35 since the ARPAnet was created, and a decade since the release of Linux 1.0. Salus provides some historic context.
