Passing Objects By Reference or Value in C#
... changes to the parameter itself are seen by the caller.
So:
public void Foo(Image image)
{
// This change won't be seen by the caller: it's changing the value
// of the parameter.
image = Image.FromStream(...);
}
public void Foo(ref Image image)
{
// This change *will* be seen by...
Tetris-ing an array
..., '', commonPrefix($paths));
Now, it may overly cut two strings such as /foo/bar and /foo/bar/baz will be cut to /foo. But short of adding another iteration round to determine if the next character is either / or end-of-string, I can't see a way around that...

constant pointer vs pointer on a constant value [duplicate]
...ommend cdecl.org as a site that converts declarations, for example int (*(*foo)(void))[3], into meaningful English text ("declare foo as pointer to function (void) returning pointer to array 3 of int").

Is it possible to import a whole directory in sass using @import?
..., https://github.com/rails/sass-rails, features glob importing.
@import "foo/*" // import all the files in the foo folder

Glorified classes in the Java language
... 1.5) - it allows an object to participate in a foreach loop:
Iterable<Foo> iterable = ...;
for (Foo foo : iterable) {

The Serializable interface has a very special meaning, different from a standard interface. You can define methods that will be taken into account even though they are...
Determine the data types of a data frame's columns
...
I would suggest
sapply(foo, typeof)
if you need the actual types of the vectors in the data frame. class() is somewhat of a different beast.
If you don't need to get this information as a vector (i.e. you don't need it to do something else progr...
Writing files in Node.js

Asynchronous Write

Javascript objects: get parent [duplicate]
...e references to the same object.
You could also do:
var obj = { subObj: {foo: 'hello world'} };
var obj2 = {};
obj2.subObj = obj.subObj;
var s = obj.subObj;
You now have three references, obj.subObj, obj2.subObj, and s, to the same object. None of them is special.

Lambda capture as const reference?
...ly this doesn't apply when capturing a member-variable by reference: [&foo = this->foo] inside of a const function gives me an error stating that the capture itself discards qualifiers. This could be a bug in GCC 5.1, though, I suppose.
