Flex Profiling
Yesterday, David Keutgens from Cynergy Systems presented Profiling in Flex for our Sydney Adobe Platform User Group. Although not a real Flex programmer myself, I found the presentation quite informative and enjoyable.
The topic also brings back my memory of my undergraduate final year where I almost did a thesis on Java profiling myself, which I didn’t end up doing because it was too hard for me.
Couple of things that I got out of the meeting (again bare in mind I am not a Flex programmer, so there might be inaccuracies below):
- In Flex you can profile 2 things: Memory or Performance.
- Need to be careful in cleaning up references to objects, otherwise the Garbage Collector won’t clean them.
- Use weak reference as much as possible, two ways of specifying weak reference:
- Dictionary class
- addListener
- When profiling look at objects that are called often or object that has long execution time.
Memorable comment on the night:
Q: What do you call a class that implements Dictionary but always use weak reference by default?
A: Wikipedia

Sporadic Learning
Yep, that’s my method of learning, basically I just learn whatever it is that comes to my fancy. A while ago it was Model-Glue, a week ago it was Flex, lo and behold, I am now captivated by ColdBox!
I guess this also can be considered as my weaknesses, being unable to be interested in one thing for long if I am not forced too. With learning these frameworks and Flex, there’s no one really asking me to do it, so there’s no pressure and I am completely free to choose whether I want to continue learning the technology or not. I need to prioritize better, I need to think through which of “the oh so many wonderful things to learn”, that can be reasonably beneficial to my career and to whoever that hires me (or will employ me).
I guess my sporadic learning at the moment is bounded by Adobe related things and web development in general, I haven’t stepped in to Ruby on Rails yet, although each day I am getting more and more compelled to at least give it a try.
Gmail thinks Adobe email is spam
I nearly lost my Flex’s registration code in an email that Adobe sent as Gmail classifies that email as spam. I don’t usually check my spam folder, but today I did, and I was fortunate to see that flex email amongst other spams..
Moral of the story, whilst Gmail spam filter is excellent, we still cannot trust it 100%.
Baby step to Flex
Just 2 tutorials that gets me build a SWF from Eclipse, without having Flex Builder installed (am in the process of getting the free Flex Builder 2 for studens)..
