Eight from IBM: RoHS, WiMAX, JET/Eclipse MDD, OpenBSD…
Aug 21, 2006 — by LinuxDevices Staff — from the LinuxDevices Archive — viewsIBM has published the following new technical articles, tutorials, and downloads on its DeveloperWorks website. They cover a range of interesting (though not necessarily embedded) technical topics, primarily related to Linux and open source system development. Some require free registration. Enjoy . . . !
- Standards and Specs: RoHS Bureaucracy Runs Amok — The EU has adopted a set of governmental standards for reduction of the use of hazardous materials in electrical and electronic equipment. This standard is called RoHS, and when the ex cathedra RoHS Directive came down, it was missing a little crucial piece of information — how manufacturers, distributors, and purchasers of parts could communicate to each other the RoHS status of every part.
- The end of cable? — You've heard some rumblings about Mobile WiMAX, but until recently it's all been in the abstract. The wireless world is changing very fast and WiMAX could be part of all our futures. Why stay with cable when you can grab it from the air onto your own home network? Why stay at home when your laptop with the right external card can be your TV/phone/datasource anywhere? Learn what's changed to make WiMAX a potentially devastating competitor to the telecom empire.
- Best practices for Eclipse model-driven development — The ability to create templates to codify best practices (that generate artifacts) is a powerful concept that can save you countless hours and reduce tedious coding. Get an introduction to the code generation framework, JET, which is an Eclipse technology project, that we expect many developers will use in their endeavors.
- Unix specialized tools and shortcuts — Every skilled trade has its secrets — those little tricks, techniques, and tools that make light of even the most complex task. Programmers, system administrators, and other UNIX computer professionals have their own kind of specialized tools. Learn how to leverage the many shortcuts that the Unix shell provides. With a little practice, you'll work smarter, not harder.
- Take a closer look at the most secure Unix OS OpenBSD — OpenBSD strives to be the most secure UNIX derivation. Design principles, such as code auditing, extensive use of encryption, and careful configuration choices, combine to ensure OpenBSD's secure by default philosophy holds true. This article gives you a close look at the operating system so secure that it was once banned for use in a DEF CON competition, where crackers go after each other's systems.
- Unit test your PHP code at every level — Test-driven development and unit tests are the latest way to make sure your code is behaving as you expect through changes and refactoring. Unit tests are a framework for writing tests on code and running those tests automatically. Find out how to unit test your PHP code at the module, database, and user interface (UI) level. With testing you will gain greater confidence that the code you ship to customers is running properly.
- The Ruby on Rails migration key advantages over Java frameworks — The migrations story in Java programming is not nearly as robust. Dealing with changes in the data and object model can be a difficult task. The Ruby on Rails solution has some core advantages. With all of the benefits of Rails migrations, sush as: allowing data migration as well as schema migration, and the use of model logic with your data migration, you'd expect a complex piece of code, but they are incredibly simple. This article examines Rails schema migrations, a philosophy of separating each database schema change from the base object model.
- The web development megaframework TurboGears — Developers call this project a “megaframework,” because it is made up of several pre-existing subprojects. TurboGears helps glue together a number of main components: MochiKit: JavaScript library, Kid: Templating language, CherryPy: Base Web framework, and SQLObject: Object-relational mapper (ORM). This article shows how to use TurboGears to create a Web-based shopping application and concludes with a comparison between Turbogears and Django.
