jQuery validation: .each with form
- by Kevin Brown
If I have a form of about 40 questions, how do I apply the same rules to questions 1-20, and 21-40? For example: $("#form_survey").validate({ rules: { a_ +i: {max:12, maxlength:2}, }, messages: { a_ +i:{ max: "That's too much!" } } Where the "+i" is the ideal increment of +1... Should be easy, I'm just stuck on syntax...Read the article

Source Code Browser

Hello I'm looking for a piece of relatively simple software to browse large C++ project.

Where can I find some good tutorials for C++
- by Rob
My friend has convinced me to start learning some C++, so my question is simple: where can I find some good tutorials for it? But please don't link me to the usual dry boring tutorials that only tells you the function syntax, I need more thorough explanations. I get sidetracked very easily, and I need tutorials that are more on a human level, that I'll not only learn from, but enjoy reading as well.

Fixing Combinatorica redefinition of Element

My code relies on version of Element which works like MemberQ, but when I load Combinatorica, Element gets redefined to work like Part. What is the easiest way to fix this conflict? Specifically, what is the syntax to remove Combinatorica's definition from DownValues? Here's what I get for DownValues[Element] {HoldPattern[ Combinatorica`Private`a_List \[Element] \ {Combinatorica`Private`index___}] :> Combinatorica`Private`a[[Combinatorica`Private`index]], HoldPattern[Private`x_ \[Element] Private`list_List] :> MemberQ[Private`list, Private`x]}Read the article

XCode: Function argument indentation
- by user343317
I was unable to find any solution of my specific issue. I'm using Xcode 3.2. I'd like to indent the next line of function argument just one step in from the previous line: somevariable = pow( a, b); However, Xcode's syntax-aware indenting insists on converting the above into: somevariable = pow( a, b); Where the arguments are aligned with opening parenthesis of the function. How can I make indenting be configured to match my preference?Read the article
