• What is the recommended way to do DRY web development (SASS+HAML, LessCSS, etc) in non-Ruby projects

  - by T.R.

  I've been looking to make things a little more DRY, both on my personal projects (django) and at work (JSP/struts,PHP). SASS+HAML seem to be quite popular, but, do those outside of the Rails community generally use these as well, or do they opt for other similar solutions? Which do you use, and what was the reasoning behind the choice?

• How can I debug a win32 process that unexpectedly terminates silently?

  - by Matthew Xavier

  I have a Windows application written in C++ that occasionally evaporates. I use the word evaporate because there is nothing left behind: no "we're sorry" message from Windows, no crash dump from the Dr. Watson facility... On the one occasion the crash occurred under the debugger, the debugger did not break---it showed the application still running. When I manually paused execution, I found that my process no longer had any threads. How can I capture the reason this process is terminating?

• How can I draw a shadow beyond a UIView's bounds?

  - by Christian

  I'm using the method described at http://stackoverflow.com/questions/805872/how-do-i-draw-a-shadow-under-a-uiview to draw shadow behind a view's content. The shadow is clipped to the view's bounds, although I disabled "Clip Subviews" in Interface Builder for the view. Is it possible to draw a shadow around a view and not only in a view? I don't want to draw the shadow inside the view because the view would receive touch events for the shadow area, which really belongs to the background.

• What happens when I instantiate class in Python?

  - by Konstantin

  Could you clarify some ideas behind Python classes and class instances? Consider this: class A(): name = 'A' a = A() a.name = 'B' # point 1 (instance of class A is used here) print a.name print A.name prints: B A if instead in point 1 I use class name, output is different: A.name = 'B' # point 1 (updated, class A itself is used here) prints: B B Even if classes in Python were some kind of prototype for class instances, I'd expect already created instances to remain intact, i.e. output like this: A B Can you explain what is actually going on?

• What happens to orphaned/killed async AJAX WebMethod or PageMethod calls?

  - by Armchair Bronco

  What happens behind the scenes if I make an AJAX PageMethod or WebMethod call from, say, "Default.aspx" and then I quickly navigate away to a different page, say, "Settings.aspx" before the initial PageMethod has returned? What kind of housekeeping, if any, takes place on either the browser or the ASP.NET back end? In other words, where do abandoned AJAX PageMethod calls go to die...and what is their funeral like?

• Z-index issues in IE8 while using 960 grid

  - by Shane Reustle

  I am having an issue in IE8 where my dropdown-style navigation is going behind another element. I have tried everything from setting the offending element's zindex to 1 and the dropdown to 99 and 999. I think it has something to do with the fact that I'm using 960 grid, as it worked before when I wasn't. Update: Problem occurs in IE8.0.6 but not IE8.0.7 Here is my stylesheet and you can see the issue happening here
