Managing TV with XMLTV XMLTV is a set of open source utilities for working with television schedules. It's not just for people building their own PVRs, though--with a little cleverness, you can build your own schedule applications. Brian Murray shows how he manages his family's entertainment time. [ONLamp] Testing PHP Code with PHPUnit Type; reload web site; eyeball output; fix bugs; repeat--there's a better way to write PHP code! Testing gives you confidence not only that your code works, but also that you can make changes to improve your design and flexibility without breaking behavior. Sebastian Bergmann, the author of PHPUnit, shows how his library can help to ease your development woes. [PHP]
Through Project Looking Glass with Hideya Kawahara 3D has taken over video gaming. When will it take over mundane computing areas such as file managers, word processors, and desktop environments? Maybe soon, if Hideya Kawahara and the Project Looking Glass team have their way. John Littler explores the ideas, implementations, and possibilities of 3D interfaces in this interview. [Linux] ONLamp 2005 Survey Results We recently ran a survey on ONLamp.com to find out more about our readers. Here are some of the interesting tidbits of information we learned. [ONLamp] Analyzing Web Logs with AWStats If you don't know where you are and what you're doing, how do you know where you're going? A crucial part of any successful web site is statistical analysis. AWStats is a powerful open source tool for collecting, summarizing, and reporting web statistics. Sean Carlos shows how to install, configure, and understand the output of the program. [ONLamp] Using the Root Account on Debian Debian GNU/Linux is a powerful and popular community-developed Linux distribution--and the basis for several other useful and usable distributions. With the recent release of Debian Sarge, it's better than ever. Edd Dumbill, Debian developer and GNU/Linux advocate, shows how to use the root account safely and responsibly. [Linux] What's New in ModSecurity
Two years ago, Ivan Ristic introduced ModSecurity, an Apache Modern Memory Management, Part 2 Modern Unix-like operating systems have their own characteristics for allocating and using memory. Howard Feldman explains how modern programming languages use memory, why this matters, and how to avoid memory and resource leaks. [ONLamp]
PHP Code Generation with Elisp There's plenty of near-repetition in software development; writing very similar code over and over again. Stop copying, pasting, and modifying, and start automating the process! Zachary Kessin shows how to use Emacs Lisp to generate useful and reusable database-access code for PHP. [PHP] Security Alerts TCP Tuning and Network Troubleshooting Information doesn't travel across networks in one big chunk--it goes in little packets wrapped in packets wrapped in packets. Sure, you know that, but did you know that a bit of measuring and a bit of tweaking can improve your networking performance by two orders of magnitude? Brian Tierney shows how. [ONLamp.com] Analyzing Statistics with GNU R Analyzing and graphing statistical data doesn't have to be as dry and boring as it sounds. With the GNU R programming language, it can be as easy as writing a few lines of code--R is to statistics and analysis as Perl is to text files. Kevin Farnham shows how easy it is to use GNU R productively with just a little bit of training. [ONLamp] Run Python Scripts on Your Nokia Smartphone Most users do not need a full-blown programming platform to develop small hacks for their phones. A scripting language like Python is the perfect tool to automate simple tasks and perform simple logical processing. This excerpt from Nokia Smartphone Hacks shows you how to use Python to develop and run scripts for your Series 60 device. [Python] Installing and Configuring Ubuntu on a Laptop Jeremy Jones recently bought a new laptop and decided to run Linux. Don't shudder--it actually works! Here's how he installed, reinstalled, and configured Ubuntu GNU/Linux on a Dell Inspiron. [Linux] What Is Prefactoring You've probably heard of Refactoring (the process of restructuring code without changing its external behavior), but what is Prefactoring? Ken Pugh provides the answer, then covers some of the guidelines to prefactoring in the areas of Extreme Abstraction, Extreme Separation, and Extreme Readability. Ken is the author of Prefactoring. [O'Reilly Network] Processing XML with Xerces and SAX It's rare to write an application these days and not run into the use of XML as a data interchange format. Perl, Java, Python, C#, Ruby, JavaScript, and PHP all have good XML processing libraries. Where's the love for C++ applications? It's in Xerces, a capable open source library. Ethan McCallum shows how to use Xerces and C++ to process, manipulate, search, and write valid XML with the event-based and memory-lean SAX processing model. [ONLamp] Using Perl in PostgreSQL Perl's DBI module makes it easy to use a database. That's not the only way to interact with a database, though. If your PostgreSQL database doesn't do exactly what you want, you can write server-side extensions--in Perl. Andrew Dunstan shows how to enable PL/Perl and how to write triggers with it. [Databases] FreeBSD Basics Inside a Luxury Synth: Creating the Linux-Powered Korg OASYS Defying the trend toward ever-cheaper plastic gear and soulless soft synths, this super-keyboard is designed to rock the world for years to come. Create Digital Music's Peter Kirn goes behind the scenes at Korg USA to learn how the designers finally built the dream instrument they'd been planning for 15 years. [Digital Media] Implementing MVC in PHP: The Controller The most popular "proper" way to build a web application seems to be to use the Model-View-Controller design pattern. While it sounds complex, the concepts are sound and the ease of development it provides are compelling. Joe Stump shows how the Controller part of MVC works by developing a working version in PHP 5. [PHP] What Is TurboGears (Hint: Python-Based Framework for Rapid Web Development) TurboGears is a Python-based framework that enables you to quickly build database-driven, ready-to-extend web applications. In this article, Matthew Russell takes you inside this framework for a look at its internal mechanisms, then introduces you to its creator, Kevin Dangoor. [Mac] Features Features Security Alerts Testing Web Apps Effectively with twill There's a real drive toward testing these days. If you develop any sort of application seriously, you've likely heard recommendations to write comprehensive automated tests. Is that really useful? Michele Simionato explores the arguments for and against automated testing, and shows how to automate web app testing using Python and the twill utility. [Python] REST on Rails Ruby on Rails is an increasingly popular framework for building web applications. Matt Biddulph shows us how good the fit is between Rails and lightweight REST web apps and services. [XML.com] Modern Memory Management Modern memory management isn't as simple as knowing that you have 150MB of programs to run and 256MB of memory to do it in. Modern Unix-like operating systems have their own characteristics for allocating and using memory. Howard Feldman explains how this works and shows how to analyze and reduce the memory consumption of your programs, no matter what language you use. [ONLamp] Big Scary Daemons What Is a Linux Distribution The Linux kernel may be the star of the show, but like any star, it needs a supporting cast. In this case, the supporting cast is known as a Linux distribution--a useful set of system and application programs bundled with the OS. Edd Dumbill serves up overviews of the major Linux distributions as well as the specialist distros, and for who (or what) each distro is best suited. [Linux] EuroOSCON: Remembering the End User Daniel Steinberg reports on some of the sessions and keynotes that spanned the first two days of O'Reilly's first-ever European Open Source Convention, in Amsterdam. In one way or another, these sessions--by Jeff Waugh, Alan Cox, and Simon Phipps--focused on the user. For more news items, press releases, blogs, and photos about the convention, check out our EuroOSCON Conference Coverage page. [O'Reilly Network] Assessing Web App Security with Mozilla If your web application expects only that users always follow instructions and can never do anything other than what you want, it's probably insecure. You might find it surprising how much information your app exposes to a potentially hostile world. Shreeraj Shah demonstrats how to use Mozilla's LiveHTTPHeaders extension to see what your app does and probe it for vulnerabilities. [O'Reilly Network] Security Alerts OpenBSD 3.8: Hackers of the Lost RAID Every six months, the OpenBSD team releases a new version of their OS. It's time for OpenBSD 3.8. Federico Biancuzzi recently interviewed the core developers about new features and improvements, as well as ongoing struggles to find support from hardware vendors. Here's what to expect when you upgrade. [BSD] A Simple Mac OS X libpng Example with OpenGL When playing with OpenGL, most folks quickly tire of simple line-drawn polygon examples and want to play with more challenging concepts--such as putting texture maps onto those shapes. In this tutorial, Michael Norton shows you how to use the PNG format to create those texture maps. [Mac] What Is Ruby on Rails Ruby on Rails is an impressive web development framework that will soon reach version 1.0. While there's a lot of buzz, it can sometimes be difficult to discern the steak beneath the sizzle. Curt Hibbs walks through the features and pieces of Ruby on Rails to show how it fits together and where its big benefits come from. [ONLamp] Lightweight Web Serving with thttpd Apache httpd is full of features and abilities, but sometimes it's too heavy for simple sites or static pages. In some cases, a simpler, lighter web server is a good alternative (or addition). Julio M. Merino Vidal demonstrates how to install and configure the simple, fast, and powerful thttpd to serve simple static and generated content very quickly. [BSD] What Is the Linux Desktop Much has been made of predictions about the "year of the Linux desktop," but what is the Linux desktop, why should we use it, and why should you care? Jono Bacon takes a look at development of the Linux desktop, from its roots to its apps to its future prospects. Jono is the author of Linux Desktop Hacks. [Linux] Tell Us What You Think: The ONLamp Survey We're asking ONLamp readers to participate in our annual online survey.
