IBM has published the following eight technical articles, tutorials, and downloads on its developerWorks and alphaWorks websites. They cover a range of interesting (though not necessarily embedded) technical topics. Some require free registration. Enjoy . . .

• From monolithic to grid: a brief history of computing — How did we get from there to here? The history of computing is marked by ages. In each age, the basic design of how we work with computers changes. Many people probably think we're in the brave new Internet age at this time, but considering the nature of computing, we're likely just at an intermediary stage. We're just now peeking into the next age — the age of the truly distributed computing system — the coming of the grid.
• Developer's notebook: Tips from veteran Linux programmer — The author is one of the top Linux developers around, and a long-time UNIX champion. Fellow Linux developers will benefit from the useful, common-practice shell scripting techniques that the author and his Codemonks Consulting partners employ on a daily basis in their Linux development and applications services work.
• Programming Linux sockets, Part 1 — This introductory-level tutorial shows how to begin programming with sockets. Focusing on C and Python, it guides you through the creation of an echo server and client, which connect over TCP/IP. Fundamental network, layer, and protocol concepts are described, and sample source code abounds.
• Secure programmer: Validating input — In nearly all secure programs, your first line of defense is to check every piece of data you receive. If you can keep malicious data from entering your program, or at least keep it from being processed, your program becomes much harder to attack. This article shows how to validate input — one of the first lines of defense in any secure program.
• Design Pattern Toolkit — Design Pattern Toolkit is an Eclipse-enabled tool for generating applications based on customizable, model-driven architecture patterns. This tool automates the use of the best known application development practices. With Design Pattern Toolkit, an expert in the art of developing a particular class of application (such as portlet, Web service, or JDBC bean) can encode the implementation steps that take application requirements and produce a complete, working application.
• System recovery with Knoppix — Rescue a non-booting Linux system, edit files, mount networked filesystems, and do a bare-metal rebuild with only a Knoppix disk and an Internet connection. This article shows you what to do when good disks go bad.
• Linux links wirelessly — Systems administrator and book author Tom Syroid teaches you how to configure a wireless network card under Linux. Upon completion of this free tutorial, you'll know how to set up a Linux laptop for wireless transmission using Gentoo distribution as an example.
• WML with PHP — When you're working with the Wireless Markup Language, you should know that it can get more dynamic with the use of PHP. Contributor Vivek Malhotra takes you through sample Hypertext Preprocessor tasks. Following this free tutorial, which contains detailed sample code, you'll be able to create dynamic wireless and Web pages.
