For some reason I though I posted this on my blog, but tonight I noticed I had spaced it. My latest installment of the Flex Performance series on O’reilly InsideRIA was published on July, 17th. You can read it here:

Oh, and while you’re there check out some of the other series. There’s a bunch of really good stuff there!
All I gotta say is:
And this:
I need to catch some zzz’s…signing out…oh, and the source images used above belong to companies with big $$…you know © for them or something like that.
I need to blog code samples more. To be quite frank, I don't because something in my brain always tells me my posts have to be polished and verbose and I'm always short on time. That's probably why I have a bunch of unfinished drafts sitting in my wordpress db. That being said, I'm going to attempt to short circuit my brain to allow me to post quick snippets and as a result hopefully quicker and more useful blog posts...we'll see how it goes.
So, here's the first attempt. Earlier this week a colleague of mine asked if there was a cool way to E4X filter on attributes without having them cause an RTE. The RTE would be generated in the case of nodes that don't contain the attribute.
Here's a sample block of XML:
We want to filter based on @someAttrib, but when you use the E4X predicate filtering syntax, the app will RTE on the first node since it doesn't contain @someAttrib. Due to the RTE, what my colleague was doing was surrounding his code in a Try/Catch as the following example illustrates:
My colleague knew there was a better way, since he knows Try/Catch can very slow. So he posed the question. I answered quickly since I got to promote one of my favorite functions in AS3: hasOwnProperty(). Here's the revised code block:
Enjoy!
I must have been pretty out of it, but apparently I ran into the 360|Flex guys at the Blue Monkey the other night and had a blast...read all about it:
Talking with them about the upcoming 360|Flex...I also guess it got a little wild upstairs.
Anyway, that reminds me, you need to get registered to go to 360|Flex. Here's the link:
Also, if you want to see who else they've run into recently, here's a partial list (hit up the 360 Flex site for more):

All I gotta say is be there or be square!
Adobe MAX is the yearly premiere event that encompasses all things Adobe...Flex, AIR, ColdFusion, Photoshop, you name it. This year it's going to be November 16 - 19, 2008 in San Francisco, California. This will be my third year at MAX, and thanks to Ted Patrick and CO, they just keep getting better and better.
That being said, I'm very excited to be speaking at MAX 2008 about the wonderful and powerful Debugging and Profiling features of Flex Builder 3! For those of you that have seen me at past conferences such as MAX, 360Flex, Webmaniacs, RIADevShed, and FlexCamp you'll know that I'm a sucker for good debugging tools and techniques and I love talking about this set of topics.
You can keep posted on updates to this session by using the outstanding RIA session scheduler at the MAX site and although it's early and the time and date is subject to change, here's the current abstract on the session:
Debugging and Profiling with Flex Builder
Learn how to use the powerful debugging and profiling tools included within Flex Builder to build high-performance, reliable applications. We'll cover some advanced debugger features you may not know, as well as go into detail about how to get the most out of the profiler.
Speakers: Jun Heider
Products: Flex Builder, Flex
When: Wednesday, November 19, 11:00 am - 12:00 pm
I'm planning for it to be an informative and entertaining session, and if there's a chance you'll be there and have some ideas on content you'd absolutely want to see feel free to let me know.

See you there!
360|Flex Send a Team or an Army - http://tinyurl.com/5vm594
360|Flex is already a great deal at the full price of $480. However, what's even more amazing is the $375 per ticket price when you register as a 4 person team. It's no wonder that companies are taking advantage of this deal and are sending whole teams. If you haven't registered yet, you'd better hurry. When teams buy in bulk, the number of available tickets dwindles fast.
