Hi!
I want to be able to apply an operation f: (T,T) => T to two Option[T] values in Scala. I want the result to be None if any of the two values is None.
More specifically, I want to know if is there a shorter way to do the following:
def opt_apply[T](f: (T,T) => T, x: Option[T], y: Option[T]): Option[T] = {
(x,y) match {

Maybe you consider this question trivial but im just curious what is your opinion.

I'm getting huge differences when I pass a float from C# to C++.

Given the requirement:
Take an object graph, set all enum type properties based on the processed value of a second string property. Convention dictates that the name of the source string property will be that of the enum property with a postfix of "Raw".
By processed we mean we'll need to strip specified characters e.t.c.

void* GetData()

I am receiving a BASE64 encoded string from a WebService. The string represents an HTML page, and I can use built-in ColdFusion functions to convert and display it. However, I need a GIF representation of the HTML page, and I'm wondering if there's any way to do this using ColdFusion.
In NumPy functions, there are often initial lines that do checking of variable types, forcing them to be certain types, etc. Can someone explain the point of these lines? What does subtracting a value from itself do?
t,w = asarray(t), asarray(duty)
w = asarray(w + (t-t))
t = asarray(t + (w-w))

I'm writing some code, and I need it to catch the arguments and pass them through fmt.Println (I want its default behaviour, to write arguments separated by spaces and followed by a newline). However it takes []interface {} but flag.Args() returns a []string. Here's the code example

I will later this year start on a project (embedded hardware, C, small company) where I believe that most (if not all) code will be new.
So what experiences do you have to share as advice to starting a new code base? What have you been missing in projects that you have been working on? What has worked really well? What…
