apollo file api overview
i was recently given the opportunity to present an introduction to the apollo file api's at apollo camp. the event itself was a huge success with an eager and inventive crowd devouring code well into the evening. during kevin lynch's keynote, he mentioned that it should take flex developers only a few minutes to get their applications into apollo. but what comes next?

presenting crud at 360flex
everybody seems to be blogging about their presentations and/or presence at 360flex, so i thought i'd join the mix. i'm actually in san jose right now, but headed home for the weekend in an hour or so. i'll be returning on sunday night ready to network, present and otherwise have fun with fellow flex developers. my topics are "5 minute crud with fds" and "flex with java".

on flexing the 1040 (us tax form)
let me preface this post by saying that perception is reality. that is to say that sometimes all you really need to do is instill the vision of what's possible, and the rest will take care of itself. in the software world we call this a "demo". setting vision and demonstrating the possibilities of adobe software is something i do on a daily basis. with that in mind, i was recently tasked to come up with a flex version of the irs form 1040 (annual taxes for those outside the united states).

data synchronization visualization
among the many valuable features of adobe flex data services is the ability to keep client-side applications in sync with their appropriate data-structures on the server. while this generally means relational databases and lists or tables of data on the client, it doesn't always have to be that way. i recently came across an interesting scenario, which afforded me the luxury of building an application that represented client-side data outside of a list.

thoughts on accordion usability
it's no big secret that i'm not a particularly big fan of the accordion control. in almost every case i encounter, the use for the accordion is to provide an alternative view to stepping through complex forms. while it can certainly be made to accommodate this use-case, it has to be one of the most abused applications of the container. what's worse is that i fear we'll see a lot more of it in the not too distant future.

yet another webcam barcode scanner
let me be clear right up front - i didn't come up with this idea. in fact, i've seen no fewer than three other web-cam barcode scanner implementations. this first one i saw was shortly after the release of flash player 8 with the introduction of the bitmap api's. you can still use this version and access it as a component on barcodepedia. renaun ericsson has also created a web-cam barcode scanner using actionscript 3 complete with a flex 2 user interface. i also ran across an implementation on the webqem blog.

context menus revisited
after encountering a security sandbox limitation in my previous example, i update the post with a scaled-down set of images that are accessed from the same domain. i'll say more on that topic later. then i got a comment from brian ferris saying that he was confused by my post as it was contradictory to the documentation. brian quoted the documentation which has the following to say about context menus.

flex 2 context menus
one of the first tips i give to flash developers getting into flex for the first time is to forget what they know about flash. i was helping a customer with a proof of concept application the other day, and got bit by not following my own advice when the requirement to have context menus came up. this feature has been available since flash player 7, but i wasn't familiar with how to implement it on flash player 9 with flex 2. after burning several hours trying it the flash 7 way, i landed at the flash 9 way.

image processing algorithms
image processing algorithms have long been one of my favorite areas of study. it's the genesis for a number of my central examples (i.e. exif data and hex editor), so you can only imagine that i'm super-excited about apollo. of course manipulating bitmap data has been possible in actionscript since flash player 8, and has only gotten better (due to performance) in flash player 9. taking this to the extreme (perhaps) is fauxto.

borders, corners and shadows, oh my!
ever have the problem of getting a ui composite and wondering how you are going to implement it? i had one such example come across an internal flex questions list the other day. i've been helped countless times by the list, so i try to at least put some thought into every question that comes across. this one however had screenshots of the problem inline with the question. it caught my attention and i couldn't help but think that "we should be able to do that with flex."
