Using dependency injection and annotations in Android for cleaner code

Interesting overview of possibilities for cleaner code using dependency injection and annotations by using the RoboGuice and/or


Android Annotations


frameworks:

Clean code in Android applications

Definitely interesting possibilities, but these frameworks are quite young. And is it really worth the effort, since Activities and Intents can also be used quite effectively to keep the app loosely-coupled? Also the libraries will increase the app's size.

Not convinced yet :)

Best of this Week Summary 06 April - 12 April 2009

• Big news this week was of course that Google App Engine now also supports Java, though still in closed beta. Other reports of this news can be found here, here, and this summary from the related Campfire '09. A nice two pager overview can be found here. Also immediately available is an Eclipse plugin. Groovy is supported too btw.
  
  Note that the Java 1.6 support is not (yet?) 100%:
  
  
  • It hasn't passed Sun's Java certification tests
  
  
  • Over 7 items of what's not supported are listed here.
  
  
  • 9 mostly similar are listed here.
  
  Here's a runthrough of getting a Wicket Hello World example running on GAE.
  


• Google also tries to introduce a new standard to easily take your contacts with you to other sites: Portable Contacts. It's used in combination with OAuth.
  


• Interesting, this opensource XSS bookmarklet (thus javascript) scans for potential XSS problems.
  
• 
  
• Talking about scanners and security, here's a free HP Flash .swf scanner that decompiles it and searches for well known leaks.
  


• Great survey results on Javascript/RIA frameworks. Questions surveyed were: which frameworks do you use the most, quality on documentation and community support, performance, ease of implementation, popularity, and 3rd party plugins quality.

• Check the elaborate 95 slides comparison of Javascript libraries at the bottom of this post. It's a presentation by John Resig, Mr JQuery. The presentation is very objective. Compared are: Prototype, jQuery, Yahoo UI, Dojo and Mootools. Another short comparison of 14 RIA/Ajax/Javascript frameworks shows jQuery as the winner, as seen by the User eXperience reviewer. Great news for jQuery this week anyway: both Nokia and Microsoft are adopting it as part of their official application development platform.
  


• Can't get enough of these RIA frameworks comparisons? Here's another one, which is a short comparison/intro of three Rich Internet Application frameworks: Adobe AIR, Google Gears and Silverlight. See also my (bit older) post here, which also includes JavaFX.
  


• Summary of an article by Martin Fowler on how Agile can be used in building SOA implementations. The answer: yes you can quickly get value out of it. The biggest proof is the internet: loosely coupled and many unexpected changes.
  


• Quick-start JSF book free for download. Only 65 pages. Beginners level, step-by-step. With some mixed "infomercials" about the soon to be open source Eclipse IDE extension Exadel Studio Pro, but not in an annoying way.
  


• Key API design points from Joshua Bloch, Chief Java Architect at Google
  


• An explanation why a canonical message model (CMM) is a "good thing" in SOA and ESB.
  


• How to manage and lead geeks in a team. For technical and non-technical teamleaders.
  

Best of this Week Summary 8 September - 14 September 2008

• An interview with leads of PHP, JavaScript, Ruby, Perl, Python, and Tcl on the state of these dynamic scripting languages.
  


• Interesting technical development: IE8 and Google Chrome are putting tabs in new processes instead of threads. The main reason for creating threads used to be that it takes a relative long time to create a new process and inter-process communication is slow. But, these days the processor speeds are so fast (following Moore's Law etc), creating processes is a piece of cake/can be done really fast.
  


• How do individualism and teamwork go together in an Agile development project. Why type of roles should you have and what to expect from those roles.
  


• A short comparison of 8 java web frameworks: Struts 2, Spring MVC, Wicket, Tapestry, MyFaces, JSF, Grails and Rife.
  

Best of this Week Summary 09 Sept - 16 Sept 2007

• Good discussion about the question whether CSS frameworks are useful.
  


• Quite basic but still interesting free online chapter "Beautiful tests" for a forthcoming book named "Beautiful Code". Interesting in it is that it shows that even the shortest piece of code can contain bugs, like a Binary Search implementation. Via TSS.
  


• Good tips (thoughts) on scalability of an application. Quite a large focus on threading and decoupling of tasks, and a bit on memory usage.
  


• Simple flexible little Java framework (I'd call it a pattern) to decouple event production and consumption. Check also this Ph. D thesis for an elaborate staged event-driven architecture.
  


• There's now a nice introduction with example code to create a sample application for AIR (previously Apollo), Silverlight and JavaFX. I've also added it to post where I compare these and Flash/Flex.
