• Why does C# not allow const and static on the same line?

  - by Cuga

  Why does C# not allow const and static on the same line? In Java, you must declare a field as 'static' and 'final' to act as a constant. Why does C# not let you declare const's as final? I make the further distinction that in Java, every interface is public and abstract, whether this is explicitly declared or not. Aren't const's effectively static in nature? WHy does C# balk at this?

• Why should Python PEP-8 specify a maximum line length of 79 characters?

  - by pcorcoran

What to do with wrapping should be the choice of the content consumer, not the responsibility of the content creator. Are there any (legitimately) good reasons for adhering to 79 characters in this age?

• Am I using too much jQuery? When am I crossing the line?

  - by Andrea

  Lately I found myself using jQuery and JavaScript a lot, often to do the same things that I did before using CSS. For example, I alternate table rows color or create buttons and links hover effects using JavaScript/jQuery. Is this acceptable? Or should I keep using CSS for these kinds of things? So the real question is: When I'm using too much jQuery? How can I understand when I'm crossing the line?

• how to make sub-muens line up below their parents in horizontal navbars?

  - by Joel

  Hi folks. I'm just putting together a simple nav bar using something similar to this tutorial: http://www.cssnewbie.com/horizontal-dropdown-menus/ The thing is, that I'd like to have the children lists first item to line up directly below the parent. Right now, they just go wherever I float them. Is there a way to do this without absolute positioning? I'd like to achieve something similar to what these guys have in their top nav bar: http://michaelfranti.com/
