Video: Auto-Reversing Transitions in Flex 4

First, this new flash (or would that be Flash news?):

CodeDependent now has a channel on YouTube!

Yes, finally, for all of those bored people surfing the web looking for funny videos, there is now a channel that talks exclusively about animation and graphics programming. Oh, my kids will be so happy.

Now, back to our regular programming...

Auto-Reversing Transitions in Flex 4, the next episode in the gripping and suspenseful series CodeDependent, is now available from Adobe TV.

This show is about the new autoReverse property in Flex 4 transitions. By default, Flex transitions stop any currently-running transition before running a new transition. So if you're currently animated from stateA to stateB and you trigger a change back to stateA, Flex will stop the A->B transition and then start the B->A transition from the beginning. This sometimes causing jarring behavior, where the visuals may pop to the end of the previous transition, or sometimes even worse artifacts. Flex 4 offers a new, simple property, autoReverse, which lets you tell Flex to stop the current transition and start the next one from that same point in time. In the A->B example above, if you trigger a change back to stateA when the A->B transition is halfway through, then Flex will stop the A->B transition and start the B->A transition from that midway point.

This feature is a small step toward more general, useful interruption and reversing behavior that I'd like to see in transitions eventually. There are some important constraints to this behavior, such as having to actually define that reverse transition (we don't create it for you) and making sure that your transition effects are true reverses of each other (which can include some tricks like using a Pause effect on the reverse transition to account for a startDelay in the forward transition). It's also important to note (since this just came up in my work yesterday from a use case from the tools team) that using assymetric easing (which is not the defaul) can make this tricky. So this feature is not necessarily for all situations, but it is useful for some common cases and can make Flex transitions an even smoother and cooler UI experience than they are already.

Women and children overboard

It's the Catch-22 of clinical trials: to protect pregnant women and children from the risks of untested drugs....we don't test drugs adequately for them. In the last few decades , we've been more concerned about the harms of research than of inadequately tested treatments for everyone, in fact. But for "vulnerable populations," like pregnant women and children, the default was to exclude them. And just in case any women might be, or might become, pregnant, it was often easier just to exclude us all from trials. It got so bad, that by the late 1990s, the FDA realized regulations and more for pregnant women - and women generally - had to change. The NIH (National Institutes of Health) took action too. And so few drugs had enough safety and efficacy information for children that, even in official circles, children were being called "therapeutic orphans." Action began on that, too. There is still a long way to go. But this month there was a sign that

Not a word was spoken (but many were learned)

Video is often used in the EFL classroom for listening comprehension activities, facilitating discussions and, of course, language work. But how can you exploit silent films without any language in them? Since developing learners' linguistic resources should be our primary goal (well, at least the blogger behind the blog thinks so), here are four suggestions on how language (grammar and vocabulary) can be generated from silent clips. Split-viewing Split-viewing is an information gap activity where the class is split into groups with one group facing the screen and the other with their back to the screen. The ones facing the screen than report on what they have seen - this can be done WHILE as well as AFTER they watch. Alternatively, students who are not watching (the ones sitting with their backs to the screen) can be send out of the classroom and come up with a list of the questions to ask the 'watching group'. This works particularly well with action or crime scenes with
