Release The Kraken! An Open-Source PubSub Server for the Real-Time Web
Saved by uncleflo on March 5th, 2013.
Today, we are releasing Kraken, the distributed pub/sub server we wrote to handle the performance and scalability demands of real-time web apps like Asana. What problem does Kraken solve? One of the key promises of real-time web applications is that users will see changes made by other users as they happen, without hitting reload or refresh. Many of the up-and-coming reactive web frameworks initially accomplish this by periodically re-executing queries against the database. When we were building the early prototypes of Asana, our reactive framework (Luna) was no different.

Flex 4 Component States vs. Skin States « Saturnboy
Saved by uncleflo on January 24th, 2012.
Flex 4 introduced an awesome new skinning architecture. Among other things, the new architecture provides significantly better separation between a component and its skin. Flex 4 also promotes the use of states to the point where they are virtually mandatory in any non-trivial app. And that brings us to the question of the day: How do you communicate state information from the host component down to its skin? As always, we’ll dive into some examples to explore how things work. In our first example, we just want our skin to mirror the states of its host component. So, we begin with a simple component based on SkinnableComponent. And then we add three states: base, happy, sad. Here we discuss the code.

redraw - Forcing Flex to update the screen? - Stack Overflow
Saved by uncleflo on November 22nd, 2011.
As mentioned in other answers, the flash player is single threaded, if you don't break up your work into discrete chunks that can executed in separate "frames", you're going to see jumps and stutters in the ui, which is effectively what you're seeing. If you really must see that 12% message, then it's not enough to invalidate the display list, as the display list isn't getting a chance to update until after the 56% work has completed, you must explicitly interrupt the natural event cycle with a call to validateNow() after your message has been set.
