onBoard is a massive collaborative painting and drawing canvas where you can draw, sketch, paint, zoom, rotate, screenshot or post your drawing to facebook. See other users drawing live. Today, I am releasing 3rd version (1st, 2nd) that is a little different than the previous ones. It takes advantage of Starling Framework and YCanvas and runs on GPU at 60fps, smoother than any before. For now there is a new web version available with old drawing and other tools. Mobile versions are currently not available. I am also working on a canvas/grid framework called YCanvas that is available on github (more information with next blog post). Have a look and compare cpu vs. gpu versions of onBoard…

After a few months off from mobile development, I realized I have forgotten all the necessary developer, application and market links for my Android, iOS, BlackBerry applications. Furthermore, it took me some time to gather them all back together as well as market deeplinks for all environments. So, I have decided to put the list together that will help me catch much faster next time.

While there is not much source available out there about how to prepare QTP (HP QuickTest Professional) automation test environment working with flex applications, I decided to write this post. It is not clear, nor straightforward for one who never ran QTP, and while I spend just a few hours preparing the test environment, I hope this article will help some of you to get started much faster. Basicaly what you need is QTP 11, Internet Explorer 8 (unfortunately), Flex Automation Plug-in and flex automation framework (.swc classes)…

There are some usefull apis since Flash Player 10, I have never been playing with. Yesterday, I realized one experiment with Sound + SampleDataEvent and created quick demo for converting music into a bitmap and vice versa.
There is a Sound.extract() method in ActionScript allowing you to grab raw sound data from a sound object. It provides you ByteArray of 32-bit floating-point values, which can be converted to a Number using ByteArray.readFloat(). The resulting values are -1 < value < 1...

With my latest approach to create universal parser, I came up with something simple yet mighty. SequenceParser is a simple (30 lines) class that crawles any source and matches specified list of highly customizable ISequences. While each sequence can contain list of nester sequences, you are able to parse any type of source with nested conditions and sequences. A good example can be an attribute inside a xml node, a xml node inside a xml node, an escape character inside quotas etc.
I have also created some example sequences like MatchAnything, MatchRegexp, MatchString, StartRegexpEndRegexp, StartRegexpEndString, StartStringEndString that should help to cover almost any possible parsing scenario. These sequences notifies back via callback containing parsed string, that is vital for further bulding additional logic like highlightning, validation over parsed phrases.

Your video is usualy resized and played in a custom sized rectangle, but if you need to capture the fullscreen screenshot you may be tempted to gather the original size screenshot by resizing the whole component or its part. Its not the best practice, while you need to resize and move back and forth the component etc. Here is a quick tip to make a fullsize screenshot from spark osmf based VideoPlayer using Matrix.

There are some hidden treasures deep in flex framework, you just have to dig for. Yesterday I hit by coincidence ConstraintLayout. Its a part of 4.5 SDK and is a nice layout for defining rows and columns for a table. Once columns and rows are created, your elements are not automaticaly aligned into a block, but rather any element can refer to any column/row using correct formula in style attributes. E.g. forumla left=”{columnId}:{value}” will attach your element into position of a column and offsetting it by some value. This layout also easily let you merge cells or rows etc.
