This chapter provides you with the opportunity to flex your C++ muscles by critiquing a piece of code. Can you find a better way to optimize this code for idiomatic usage? Find out in this challenge from Herb Sutter.

Pyrex is a language specially designed for writing Python extension modules. According to the Pyrex Web site, "It's designed to bridge the gap between the nice, high-level, easy-to-use world of Python and the messy, low-level world of C." Almost any piece of Python code is also valid Pyrex code, but you can add optional static type declarations to Pyrex code, making the declared objects run at C speed.

Just knowing an object-oriented language isn't enough to create object systems. You also have to learn to "think in objects." This chapter explains why it's important to understand what it means to truly be "object-oriented" and how you can build your business by using object-orientation from top to bottom.

The Ruby community is abuzz about Rails, a web application framework that makes database-backed apps dead simple. What's the fuss? Is it worth the hype? Curt Hibbs shows off Rails, building a simple application that even non-Rubyists can follow.

Has the Object-Oriented Programming been hyped too much, or do we suffer from the OO paradigms exposed in languages such as C++, Java, C#? How about languages that support features such as prototyping and/or multi-dispatch?

The old adage, "If it ain't broke, don't fix it," doesn't necessarily apply in the case of technology. Projects continually require alterations, updates, and enhancements. This chapter outlines the nature of code change, and suggests some of the challenges to be faced when making these changes.

As 64-bit PowerPC processors become more widely available, it becomes desirable to make applications run in the 64-bit computation mode, providing access to larger address space and faster 64-bit arithmetic. This excerpt from a longer Technical Library article covers some of the issues faced when porting existing 32-bit code to the new computing model -- or when embarking on new 64-bit development.

Eugene Blanchard made his Introduction to Data Communications (also known as Introduction to Networking) available for free. The book covers a broad variety of topics such as RS-232, Ethernet, RF, TCP/IP and many other topics in its 63 chapters. This is a valuable reference and read for those just starting to understand networking and data communications as well as seasoned professionals in the field.

Linux Magazine has an extensive article the technical details and motivation behind Xen by one the developers.

With Gambas, you can quickly design your program GUI, access MySQL or PostgreSQL databases, pilot KDE applications with DCOP, translate your Basic program into many languages, create network applications easily, and so on...

Navicat 5.3.1 (a cross-platform MySQL client, available for OS X, Linux and Windows) now offers support for customizable History Log path, resizable Manage User window and improves the import/ export wizards. The database management tool is an integrated GUI tool, which can perform MySQL administration and database development, enabling to import/export to and from different file formats, backup data, transfer database from server to server, create visual sql queries and manage multiple databases on local or remote MySQL server. It also includes a full featured graphical manager for setting the users and access privileges. Download an evaluation.

American RadioWorks has an interesting investigation into the longer-term effects of the Y2K scare, especially its impact on the world's IT infrastructure. Y2K was a real potential problem, which was first ignored, but then most likely over-reacted to. But it was probably responsible for the rise of the Indian offshore IT boom. It also resulted in big productivity gains as decades of cruft were removed from datacenters during the fixes. For example, when the NY Stock Exchange was able to reassmble its systems six days after 9/11, it was because of the Y2K-related work they'd done.

Autopackage, a Linux distribution neutral binary packaging framework has released a new version. New features include: First API stable release, Self contained Installers, Multi architecture support, Better documentation, Support for internationalisation, Support for Gconf schemas, A brand new graphical management software for easy uninstallation of autopackaged apps. A 1.0 release is expected by Feb 2005.

BBC's research and development team has released yet another open source project for network testing. Dubbed the Kamaelia project, released on Tuesday, is designed to simplify the creation and testing of new protocols for large-scale media delivery systems. This follows earlier efforts like the open source dirac project to create video codecs tailored towards streaming.
