360|Flex is officially over and my slides are finally available. It was another great conference but I am officially wiped out. Three full days of content and wonderfully geeky discussion have left me looking forward to the weekend.

For any who asked for my slides, they are included below. Thanks so much for the great feedback and being a wonderful audience. I really enjoy doing these deep-dive style talks and so long as 360|Flex keeps inviting me back and all of you keep attending, I promise to try to keep them fresh and interesting.

Flex 4 components from the firehose

P.S. If you didn’t get a chance, check out my featured opening over at http://www.weheartdoug.org for Nate’s masterful prank.

360| Flex and WorldWare Ahoy

March is shaping up to be a busy month for speaking, and I am pretty happy about it. I have the opportunity to deliver two distinct talks on topics where I feel, let’s just say, a lot of passion.

First up in the 360|Flex Conference in San Jose on March 7th-10th. Here I am delivering a talk about the Flex Framework and its relationship to the component development in the Flex 4 methodology. There will actually be quite a few Flex 4 talks (and even component talks) available at 360|Flex this year; however, I think this will come across differently. I intend on tearing apart the framework again along the lines of my Dense and Hot presentation a few years back. The intent of this presentation is less about what and more about why. I want you to know things like the order that nested components have their commitProperties called versus their measure when you leave. More importantly though, I want you to walk away knowing that it’s because of priority queues and nest-levels. I want you to feel comfortable explaining it to that poor guy back at the office that couldn’t make it to San Jose for the conference. That guys deserves some love to. You want to help him, right? I digress.

In either case, I hope you can make it out to 360|Flex. It is always a good event. It is chocked full of great content and I don’t know that there is a better value in the Flex conference space. If you want to be extra-nice to me, you can register with this link. Apparently if enough people register that way, John Wilker is going to carry me from place to place in some type of litter. All said though, try to make it if you can. Even if I wasn’t speaking, I would still be there learning from a great community willing to spread a lot of knowledge.

Right on the heels of 360 is the WorldWare conference in Santa Clara on March 16th-18th. WorldWare is a conference dedicated to those developing applications for an international market. I will be doing a pre-conference workshop on the benefits of using the Flex Framework, with all of its UI swapping, layout object goodness, to the benefit of those wishing to write an i18n application in a reasonable amount of time and with a reasonable expectation of maintaining it (without sleeping at the office for the rest of their lives). This year’s theme at WorldWare is the ROI of Software Internationalization and I am honored to even be considered near the profound list of speakers. If your application or company is targeting the international world this is the place to be in March.

Hope to see you at one (or both )of these events,
Cheers,

FlexUnit in Flash Builder Bugs plus TDD

I just finished my presentation materials for my Test-driven development session at Adobe Max, and I am pretty excited how it turned out. It is a 90-minute BYOL (Bring your own laptop) lab, which is always challenging. Each person showing up with a diverse setup and (hopefully) our files installed.

So, if you are planning to head to Max, and you are interested in TDD, try to attend. I think it will be well worth the effort.

That said, there will also be two sessions at the 360|Flex Max unconference where we will be reviewing the FlexUnit 4 framework from the inside out. The goal here is to provide initial context for those interested in becoming committers on the project. FlexUnit 4 is a highly functional testing framework, but it is also complex. Until we have the chance to document every corner, this might be your best chance to learn the ins and outs of it.

Finally, working on this session has given me the opportunity to work with the FlexUnit plugin in Flash Builder. I must say I am very pleased with how this is evolving. Nonetheless, there are a few enhancements I would still like. If you are of a like mind, read through the bugs and cast your vote.

If you agree, vote away. Hope to see you at Max,
Mike

Any Which Array but Loose.. the code

Posted At: May 20, 2009 9:05 PM | Posted By: Michael Labriola
Related Categories: 360Flex, Adobe Flex, Presentations

For those that attended my 360|Flex session on Array/DataStructure performance, here is an updated version of the code I was using to demo. A few things:

  1. The timing method I am using only has millisecond resolution. So, the difference between 0 and 1 millisecond could change in subsequent calls. I would pay more attention to the difference between 1 and 100, which is what we really care about.
  2. Right not the default number of items being created in each structure is set to 5000. You can change this and the insert/delete numbers by changing the constants in the main MXML file
  3. Playing with the aforementioned numbers will really help you get a sense of how these things work. For instance, it is really interesting to see the difference between sorting the ArrayCollection up front or later as the array size grows.
  4. There are (n) more variations of each of these.. using push() instead of direct addressing. Telling the vectors to be fixed size instead of dynamic. I kept this open enough that you should be able to add those cases and explore as you see fit, but I didn’t cover every permutation in this code
  5. I added some filters on the main page so that you can easily lose/add tests or datapoints to get a better view of the data
  6. I didn’t include the LinkedListCollection code in this package. I will get that out soon, but I want to clean it up and comment it. It is confusing to me right now and I wrote it

Okay, so, that’s it. Have fun and play. In the end, this is all about finding the best tool for any particular job.

A few introspection classes to keep things going

Posted At: April 23, 2009 9:04 PM | Posted By: Michael Labriola
Related Categories: 360Flex, Adobe Flex

Okay, it has been way to long since I have had the opportunity to post anything of value. So, here are a few classes I wrote called Constructor, Field, Method and Klass. They also use one additional class named MetaData tools. These classes roughly mirror the java.lang.reflect classes. They aren’t quite as thorough, but there is some good stuff in here.

In the next few weeks these will be released as part of a larger project, but I thought I would take the opportunity to throw these early versions online as I have found them extremely useful over the last month. In addition to the ‘normal’ stuff you would expect in introspection, these also take care of a few gotchas that you might run into if you are used to Java and now play in the AS sandbox.

First, the default describeType method of the flash.utils package doesn’t actually know how to get constructor parameters from the metadata until the class has been constructed, in some capacity, once. This is really frustrating but can be handled by doing a behind the scenes instantiation and capture. Not gorgeous, but it works and gets me the parameters I wanted.

Second, DescribeTypeCache has a few issues regarding when a description is cached. If you cache it for the first time before the first instance is built, you will forever get that version back. This means that the cached record may look different dependent upon the order you called it… so not cool.

Third, pre-flash player 10, you can’t specify that an array will contain a given type of data. Flex has a metadata tag called ArrayElementType, which MXML will respect (in some cases) but overall it is mostly useless. This library will actually look at that ArrayElementType at runtime and at least tell you what data you expected to go into the array. This is actually quite useful in a number of situations ( however, you need to ensure you instruct your project to keep the ArrayElementType metadata.

Fourth, you can fake out having a constructor.apply() at least for a limited set of arguments.

Fifth, actually, I’m not sure what’s fifth, so just grab these classes and give them a whirl if you are interested. I promise they will be documented and have some asdocs by the time they are released, but these are a start.

Also, in the next month I will be presenting at both 360|Flex Indianapolis and webDU (within a few days of each other). These are two of my favorite conferences. They both have a unique message and a great crew behind them. I hope to post more about these soon, but if you can make either of these conferences, I would love to sit down and explain the bigger picture of where these classes come from, and, hopefully, get you playing with some very interesting new code.

Vote if you want ridiculous amounts of detail at 360 Flex Indy

Posted At: January 20, 2009 10:01 AM | Posted By: Michael Labriola
Related Categories: 360Flex, Adobe Flex, flexcamp

Okay, so I haven’t managed to post anything of value in a while but I am hoping that is about to change. Over the coming weeks and months, I plan to start posting ad hoc classes I have found useful or just little snippets that might save you some time. Hopefully, that will give you a reason to come back and visit.
In the meantime though, voting has opened up for 360 Flex Indy. Votes are being tallied for each session and, as I understand it. The top ones get presented. So, for any of you that enjoyed ‘Dense and Hot’ and ‘The Ties that Bind Us’ (aka Diving in the Data Binding Waters) you may want to log in and vote for my latest session ‘Any Which Array but Loose‘. Continuing the trend of ridiculous deep dives on Flex topics, I decided to tackle the various array types available with Flash Player 10. I am at a bit of a disadvantage though. Since I updated my description after the site launched, I seem to have lost any initial votes on my topic. If you vote, I do promise that there will be much more information presented then you could possibly want.

Also, Thursday and Friday, I will be at Flex Camp Chicago. A sold out event in Chicago with a lot of great speakers. For anyone who is attending, I will be hanging around for the balance of the days, so feel free to come up, introduce yourself and talk Flex. I will be happy to answer any questions I can or help you around a problem in code.
Cheers,
Labriola

360 Flex San Jose Recap

Posted At: August 20, 2008 3:08 PM | Posted By: Michael Labriola
Related Categories: 360Flex, Adobe Flex, Presentations

I am back in Chicago after a red-eye from San Jose this morning where I was attending 360 Flex. It was yet another wonderful conference put on by Tom and John featuring great presentation and fantastically inquisitive attendees. For my part, I ended up doing two back to back sessions on Drag and Drop with AIR and a deep dive into Flex Data Binding.


The AIR session was originally Jeff Tapper’s to do, but he selflessly agreed to hang back when a client emergency kept him working during conference hours. I did my best to fill in for him and hopefully the audience gained some tips and tricks when moving between these technologies.


The data binding session is one I have been looking forward to for quite some time. It is another of my ‘Flex from the Inside Out’ style presentations where I attack a narrow topic and try to bring light to the darkness. It seemed well received and the crowd seemed to very interested, which makes it worth the effort.


The slides for both of these presentations can be found at SlideShare. The download URLs for these presentations are as follows:

Please send any feedback you have so I can make these better for the next time around.


Thanks,

Want to really learn Adobe Flex?

Posted At: July 14, 2008 9:07 AM | Posted By: Michael Labriola
Related Categories: 360Flex, Adobe Flex, Presentations

Next month (August 18 – 20) I will be speaking and listening at 360|Flex San Jose along with a cadre of some of the best Flex speakers in the world. While this conference certainly offers a ton for beginners and those adopting Flex, 360|Flex distinguishes itself by also offering content for intermediate and advanced teams.

This is a huge deal. Flex teams and developers are growing and evolving but many of the conferences and books (including my own) only focus on beginners. So how does a developer get to the next level in Flex knowledge? That is the most common question I am asked during consulting and mentoring gigs these days. My answer: Start by registering for this 360|Flex San Jose 2008. You will absorb an amazing amount of content, meet some really great people and learn a lot for a really reasonable price.

My topic specifically is about data binding. You know, those stupid little curly brackets that make all of the magic happen. Well, we are going to reveal the magician’s tricks, break it all down and learn it from the inside out. I promise you will leave the session with knowledge that will scare your peers and allow you to do horrible things that the Flex framework engineers never intended. Which is pretty much the goal of most of my sessions…

I hope I have the chance to see you there, so register and don’t delay. They will sell out and then you will be sad.

As though its been years…

Okay, so since the last time I managed to blog, I had an excellent time presenting ‘Dense and Hot’ in Milan Italy for 360 Flex. It was a great time with a great bunch of presenters. I am looking forward to what Tom and John manage to do with their next conference. Cheers Guys. I presented at a few events for Adobe and BEA, Flex Camp Wall Street, the Boston Flex Incubator group and the new Chicago Flex User Group. This week I am out in San Jose for the Adobe Community Summit and learning about the amazing things Adobe has in the pipeline. All I can say, is the next year is going to be exciting. Next week I am presenting a hands-on lesson in advanced component development and skinning at WebManiacs. Followed closely by ‘Dense and Hot’ at webDU in Sydney Australia. And just to bring things back around to the beginning, I will be presenting a brand new presentation at 360 Flex San Jose in August. It’s an hour and twenty minutes on the internals of data binding, which will, in my professional opinion, be absolutely awesome. Attached to this post are all of the slides I have been promising. Next week I will post the WebManiacs slides. To all those that made these past events great, thanks, each of these events was fantastic in its own way. I hope to see the rest of you at WebManiacs and 360 Flex. Labriola Download
