This InfoQ video talk, recorded at NoFluffJustStuff, goes beyond myths surrounding AOP and shows the real deal. It examines many practical applications implemented with and without aspects, providing a context for scrutinizing AOP. It also discusses ways to adopt AOP in pragmatic, risk-managed ways allowing developers to try AOP in their own system and gain understanding at the experiential level without exposing them to undue risk.

Watch AOP - Myths and Realities (82 minutes).

Author, speaker, consultant, and trainer, Ramnivas Laddad has been developing complex software systems using technologies such as Java, J2EE, AspectJ, UML, networking, and XML for over a decade. Ramnivas is an active member of the AspectJ community and has been involved with aspect-oriented programming from its early form. Ramnivas this year joined the Spring Interface 21 team, and will be speaking at The Spring Experience.

Ramnivas is also doing a training: Core AOP: Simplifying Enterprise Application Development with AOP in Novebemer in Washington.

   minor bugs - our first video!

   by Floyd Marinescu

   This is among InfoQ's first videos, and we have a couple of minor known bugs that may affect a minority of people:
   - if you're on a slower internet connection (512 or less) - you may need to refresh the page once or twice before it starts to work
   - if you don't have Flash 8+ installed, you will only hear audio - please upgrade (you should see a message to this effect on the interface)
   
   We are working on solving both of these... We hope you enjoy this video, it is the first of many! :)

   nice

   by Sandeep Khurana

   Nice presentation, even a new comer like me could understand. Some suggestion,
   1. Can such a big demo can be split into parts of small demos too ? And give a choice to watch full demo or demo in parts?
   
   2. Is there any possiblity for the code which was shown in demo to be downloaded ? So that we can play around?
   
   3. Was there no question asked by the audience there? If there were questions asked, would be helpful to present the Q&A session too.
   
   4. Although the presestation slides showed some references for further readings, but is it possible to have some sort of resource section here for books, sites , tutorials etc for the topic presented ?

   Thanks, Sandeep.
   
   

   
   2. Is there any possiblity for the code which was shown in demo to be downloaded ? So that we can play around?
   

   
   
   You should find most code as a part of AspectJ in Action's downloadable source (www.manning-source.com/books/laddad/laddad_src_...)
   
   

   
   3. Was there no question asked by the audience there? If there were questions asked, would be helpful to present the Q&A session too.
   

   
   
   I think I remember wondering about no questions, too (usually, there are quite a few questions). I think Floyd's camera intimidated the attendees :-).
   
   

   
   4. Although the presestation slides showed some references for further readings, but is it possible to have some sort of resource section here for books, sites , tutorials etc for the topic presented ?
   

   
   
   See my article on the same topic that includes the information you are seeking:

   A text version ?

   by ZedroS Schwartz

   Hi
   
   Is there some way to have some text based support for this presentation ?
   
   Not all of us can access to the video and/or have sound on, so any other support is welcomed. For example, could some presentation slides be available ?
   
   Thanks in advance

   Please provide a means for downloading the video also. I have a slow connection to internet, so playing the flash video is jerky and with many pauses.
   Thanks........Vijay.

   I "get it" now.

   by Chad Bradley

   Thank you for your presentation. It is well done.
   
   I had not been convinced about aspects before. When hearing how people were using it I had always thought of it as a hack.
   
   I "get it" now.
   
   I would love to see an article or video that concentrates on unit testing best practices. It has taken years of experience to write code that is easily testable. The result is alot of test code and fixtures that is not near as pretty as the production code. I can see how aspects could make unit testing even simpler and make production code less complex, yet just as testable.
   
   Great job Ramnivas!

   I still don't buy it.

   by Jonathan Allen

   I still don't believe that AOP is worth losing code localization. Aside from logging, I saw nothing that I would like to use in production.
   
   By the time the speaker is done, there is no code left in the actual classes. At that point, why have the actual classes?
   
   Many of the examples were trying to solve problems created by overapplying design patterns. Dynamic proxies, observer patterns, factories, and other such nonsense are so rarely needed that they should be alien topics to most programmers. The fact that they are seen as as problems to be solved showed they are improperly used.
   
   Now, if AOP was positioned as a cool way to do tracing and logging I would buy into it. Integrate it into a good test bench and you have a killer tool.

   I knew a very little about AOP before I saw your presentation RamNivas. I would like to get up to speed on writing my own Aspects. What is the best place to start?
   
   Thanks a bunch!
