    IE Memory Leak Best Practices with AJAX in Mind

    Am I getting obsessed with memory leaks?  Give me a non-leaking browser and I'll cut it out .Yesterday I was hunting for a hard-to-find memory leak with r.a.d.treeview.  Our component cleans up its DOM element references and DOM event handlers when it is being destroyed.  Control destruction and resource disposal occurs on two occasions:  when the page unloads and when the control is updated by an AJAX call (r.a.d.callback, Atlas, etc -- the mechanism is framework-agnostic).  Now the treeview, being a good citizen, follows the leak prevention pattern of keeping references to DOM elements to a minimum.  Most of the...

    Automating Complex JavaScript-rich Controls with Watir

    Playing with minimo

    With mozilla minimo recently released it will be interesting for web developers and geeks alike to mess around with it. For those not familiar with minimo it is basically mozilla’s alternative to pocket internet explorer for PDAs, smartphones and other devices that use Windows CE. And yes, it does have tabs! Here is what we can read on the official website (http://www.mozilla.org/projects/minimo/): The Minimo has been focused on code-size and runtime footprint reduction, small screen usablity, and porting to small consumer devices. We hope to make Minimo the browser of choice on small devices, or machines with limited system resources; taking advantage of...

    Glassy buttons, interrupted?

    Has the time come to challenge the top place of glassy look in today’s web notion for haute couture? What could possibly act cooler than a glassy button on your web site? Admit it, even if you never had it, at one point or another you secretly craved for one.

Everyone’s got it - for the last couple of years, web interface has been all about this glassy feel – ironically enough, with the fall of the...
