10 from IBM: SSH, JSON, Mylyn, iPhone web apps, Web 2.0…

Aug 17, 2007 — by LinuxDevices Staff — from the LinuxDevices Archive — 3 views

IBM has published the following new technical articles, tutorials, and downloads on its DeveloperWorks and AlphaWorks websites. They cover a range of interesting (though not necessarily embedded) technical topics, primarily related to Linux and open source system and application development. Some require free registration. Enjoy . . . !


  • Distributed administration using SSH — Use Secure Shell (SSH) to run commands on remote UNIX systems and, with some simple scripts, put together a system that enables you to manage many systems simultaneously from one machine without having to log in directly to the machines themselves.
  • Mastering Ajax with JSON on the server side — As discussed in the previous article in this series, JSON is a useful format for Ajax applications because it allows you to convert between JavaScript objects and string values quickly. In this final article of the series, you'll learn how to handle data sent to a server in the JSON format and how to reply to scripts using the same format.
  • Extend the Eclipse SDK with Mylyn 2.0 — Now in release 2.0, Mylyn (formerly called Mylar) enhances productivity by seamlessly integrating tasks into Eclipse and automatically managing the context of those tasks as you work. Part 1 introduces Mylyn's task management facilities and integration with repositories such as Bugzilla, Trac, and JIRA. You'll learn how context management eases multitasking and reduces information overload in Part 2.
  • Ease multitasking for Eclipse with Mylyn 2.0, Part 2 — This second half explains how Mylyn's context management facilities make multitasking easy and reduce information overload when you're working on large applications in Eclipse. Part 1 introduces Mylyn's task management facilities and integration with repositories such as Bugzilla.
  • Build an iPhone remote control — Use PHP combined with Joe Hewitt's iUI toolkit to build a Sailing Clicker like application (a remote control for a Mac and windows). The toolkit builds an iPhone-looking interface, and handles the feel of the interface. For example, as you page through a list of items, iUI sweeps from side to side, just like an iPhone application does.
  • Web 2.0 Goes to Work — During this day-long technology briefing from IBM, you'll see demos of the hottest technologies and participate in interactive breakout sessions – a large part of the content will be driven by you and the
    other attendees as we go along!
  • Google Mashup and Web 2.0 storage solutions — Google Maps API along with DB2 or Informix, PHP, JavaScript, and XML let you create an easy-to-use map with your data on it. Use custom icons, change the map type, create a sidebar, and use event handlers. Once created, manage your mashup data cache. Also, be sure to check out how you can use new Web 2.0 tools, principles, and practices in your company.
  • Track down and squash pesky PHP bugs — Tracking down bugs in PHP code can be a challenge. But if you have a development system and can install Xdebug, squashing those bugs becomes a lot easier. Xdebug can show a stack trace, dump even complex variables, track memory usage over time, and allow you to conduct an effective post-mortem when an error or crash occurs. This is a good way to get introduced to PHP tools that simplify your PHP debugging.
  • Develop multitasking applications with PHP V5 — Many PHP developers believe that because standard PHP lacks threading capabilities, it's impossible for a practical PHP application to multitask. Not true… PHP doesn't support threading in the way other languages like the Java programming language or C do, but the examples in this article show that PHP can exploit in-process multitasking and has more potential for speed-ups than many realize.
  • Testing strategies in Ruby on Rails — The Ruby on Rails community embraces testing like the USA embraces American Idol. They watch their test case results roll by with great regularity. Ruby developers talk about testing; they blog about it; they even participate behind the scenes, not with cell phone votes but by contributing open source frameworks. Learn about the trade-offs of several Ruby on Rails testing strategies. This article walks you through the basic out-of-the-box testing techniques, and how those compare with the newer mocking frameworks.
