I want to implement greatest integer function.
int x = 5/3;
My question is with greater numbers could there be a loss of precision as 5/3 would produce a double?
EDIT: Greatest integer function is integer less than or equal to X.
Example:
4.5 = 4
4 = 4
3.2 = 3
3 = 3
What I want to know is 5/3 going to produce a double? Because if so I will…
I have a bug in my code caused by a premature freeing of a ObjC object. I seem not to be able to find it by just looking at my code.
There's usually a simple trick to track the dealloc to any class: Implement dealloc, and set a breakpoint. This even usually works with standard objects, by subclassing them and making sure I instantiate the…

In a small Ruby application, I'd like user input to be accepted without having to wait for a carriage return. My understanding is that cbreak mode needs to be enabled in order for the terminal to feed user input directly into the script.
I tried simply running x%[cbreak()] at the top of my script but that didn't…
We are currently discussing the Best Practice for placing the @Transactional annotations in our code.
Do you place the @Transactional in the DAO classes and/or their methods or is it better to annotate the Service classed which are calling using the DAO objects? Or does it make sense to annotate both "layers"?
Hi,
I have a class
class foo {
public:

static const string s;

Where is the best place to initialize the string s in the source file?
Usually, when a View requires a lot of bindings, or some UI Elements like a Bing Map, it takes a "while" to load (like between half a second and a second).
I don't want a delay between a "tap" action (like tapping an element on a ListBox) and the navigation action (displaying a new page).
I don't mind…

How do I find the MAC address of a network card on IRIX? I'd rather not shell out to something that displays it and parse the output.
I'm coding C.
Methods that require root access are acceptable.
We unfortunately find ourselves having to support our product in IE 6 because some of our largest users use it. One of them called today and told me that one of the dropdowns doesn't work when he clicks on it - it simply selects the first item.
I checked the markup and the entire contents of…
I often run into the problem that I have one stream full of data and want to write everything of it into another stream.
All code-examples out there use a buffer in form of a byte-array.
Is there a more elegant way to this?
If not, what's the ideal size of the buffer. Which factors make up…

Greetings,

A table can only store 10 records in a particular state, 10 users over 30 years for example, the others must be less than 30 years. It is a business rule and as such should be respected. How to ensure that state? Think: multiple users accessing this table.
I'm implementing a custom control that inherits from Control. I want it to be focusable (it's a kind of list box).
In the constructor, I do
SetStyle(ControlStyles.Selectable, true);
I can now use Tab to navigate to the control.
However, when the control receives a mouse click, it…
