The content of {{article.content_html|safe}} are paragraph blocks, and I just wanna add <span class="label">Note:</span> in the very first paragraph. Thanks! ...
Learning C++ and see the class laid out like this: class CRectangle { int x, y; public: void set_values (int,int); int area () {return (x*y);} }; void CRectangle::set_values (int a, int b) { x = a; y = b; } I know Java and methods(functions) in Java are written within the class. The class looks like a Java interface...
Hi all, ok what I want to do is to draw a quad in the scene that lays on a plane parallel to the view. So it should appear flat. More in particular, I think I didn't get very well how the mechanism of gluLookAt works in comparison with the functions glTranslate and glRotate: If I position the view "manually" using the functions glTran...

(If that's possible... :-p) Here are my requirements for this project: module-based (has libraries/modules that compile into a main program module) compiles cross-platform I'd like to do this so that I can get a hold on the basics ...

I'm appending the text during special events but I want the EditView to scroll down to the latest text added so it'll be visible.

I am working with c++ strings, and am a beginner at programming. I am expecting: 99 Red Balloons But I am receiving: 99 RedBalloons Why is that? #include <string> #include <iostream> using namespace std; int main() { string text = "9"; string term( "9 "); string info = "Toys"; string color; char hue[4] = {'R','e...
I want to pass an overloaded function to the std::for_each() algorithm. e.g.: class A { void f(char c); void f(int i); void scan(const std::string& s) { std::for_each(s.begin(), s.end(), f); } }; I'd expect the compiler to resolve f() by the iterator type. Apparently, it (gcc 4.1.2) doesn't do it. So, how can I specify which ...
A small initiative from my work place plans to teach very basic computers to not so fortunate kids. I was looking for some very basic topics/resources. These kids are very young and have not seen/worked with a computer before. The fun factor should not be lost and hence I don't want it to be rigorous, just plain, what is computer, keybo...

Ok, i've always kind of known that computers treat strings as a series of numbers under the covers, but i never really looked at the details of how it works. What sort of magic is going on in the average compiler/processor when we do, for instance, the following? string myString = "foo"; myString += "bar"; print(myString) //replace with...
This seems like a fairly simple problem to me but I have been having some issues. In one of my views I use something like <% if current_page?(:controller => "activities", :action => "new") %> *Do something here* <% end %> and it does something specific on the new page for a form. Easy enough and it works great. Unfortunate...
