Robert M. Love, Linux kernel hacker.
"First off, of course, there is the preemptive kernel. The preemptive kernel makes the kernel schedule preemptively like user-space, as opposed to schedule cooperatively. This improves process response by allowing a freshly woken up process to immediately preempt the running task, even if the task is inside the kernel."

|Concurrency For Grown-Ups|
|Concurrency -- multi-processing -- is widely misunderstood. This article introduces the basic concurrency concepts you need to conduct your business in the server closets safely. Concurrency labels situations where more than one "application" is running at a time. Linux hosts always fill their process tables with a bunch of more-or-less simultaneous programs: network protocol daemons, cron managers, the kernel itself, and often much more. Linux is a multi-tasking operating system and it's built for this.|

|The Business and Economics of Linux|
|Linux Journal reviews the book
The Business and Economics of Linux and Open Source.
"The Business and Economics of Linux and Open Source is written for executives whose companies produce
software and for IT managers who must choose and/or deploy this software within their companies. It introduces both free and open-source
software (OSS), but predictably, the book focuses mostly on the latter.
In spite of this, actually, for these reasons, I'd also recommend the
book to hackers, for reasons that will be clear later in this review."

|Crackproof Your Software|
|Linux Lookup reviews the book
Crackproof Your Software.
"This book tries to make the average developer more aware of the ever increasing problem of piracy in today's computing world. It takes the reader through a twisting maze of cracking methods, their counter measures and so forth. It provides well written, working examples to show exactly how each counter cracking method works, so that the reader might gain a better insight into the methods a cracker might use to circumnavigate any protection written in by the lowly software developer."

|FooBillard 2.0: Not Just "Balls and a Stick"|
|Linux Orbit reviews the game
"Pool is one of the most recognizable games that most everyone knows how to play, and it just makes sense for there to be a open source version of this game for our favorite operating system. There are a few out there, and today we're going to take a look at one called FooBillard."

|Slashdot reviews the book
"It provides a solid, fast-paced drill on the rudimentaries of PHP (although the fast-paced installation instructions come in the form of classic compendia -- worth 100 pages) for seasoned programmers, before it plunges head straight into the more advanced areas of the language. Each chapter reads a bit like a tutorial on a particular area of advanced PHP development."

|Suiting All Tastes at LWE|
|Linux Planet talks about the
"This year's LWE has much of the same features that have been large draws in the past: the Taste of Linux series, the Open Source Product Excellence Awards--even the Golden Penguin Bowl. Attendees will notice that while many of the old exhibits and programs are back again this year, several more sessions have been added that are specifically targeted to the enterprise."

|Applications, User Interfaces, and Servers|
|O'Reilly brings us:
Applications, User Interfaces, and Servers in the Soup.
"To a large extent, the standalone application is already dissolving. Many people are used to doing everything from a single platform; for instance, you may have viewed and even edited a spreadsheet in your browser. And I hate to admit it, but the antitrust flap over Microsoft's integration of desktop and browser obscured the simple and obvious fact that it makes sense to integrate them. The free KDE desktop does much the same thing by integrating the file manager and browser."

|Alternative Web Browsers|
|News Factor takes a look at
alternative web browsers.
"One such browser, Opera, is often called "the fastest browser on Earth." It is also one of the few that still has a price tag. Speed and a small memory footprint are its dominant features, though Opera also pioneered tabbed browsing and mouse gestures, which have found their way into Mozilla and Konqueror, another IE alternative."
