What's the (hidden) cost of Scala's lazy val?
...) and initializes the target field in a synchronized block if the relevant xor of the bitmap indicates it is necessary.
Using:
class Something {
lazy val foo = getFoo
def getFoo = "foo!"
}
produces sample bytecode:
0 aload_0 [this]
1 getfield blevins.example.Something.bitmap$0 : int [15...
Real world use cases of bitwise operators [closed]
...t into every area where these operators are used in graphics programming. XOR (or ^) is particularly interesting here because applying the same input a second time will undo the first. Older GUIs used to rely on this for selection highlighting and other overlays, in order to eliminate the need for...

XPath OR operator for different nodes
...
Logical operators (OR, XOR, AND) are the same in every programming language but natural language interprets them slightly different. It's best to remove ambiguity when discussing issues related to them. Furthermore, with XPath it's best not to thin...
How to reverse a singly linked list using only two pointers?
...out using a third. Simply cast the pointers to a int/long and perform the XOR operation a couple of times. This is one of those C tricks that makes for a fun question, but doesn't have any practical value.
Can you reduce the O(n) complexity? No, not really. Just use a doubly linked list if yo...
A Java collection of value pairs? (tuples?)
... a true tuple. For example the hashcode implementation in SimpleEntry just xors the codes of the elements, so <a,b> hashes to the same value as <b,a>. Tuple implementations often sort lexicographically, but SimpleEntry doesn't implement Comparable. So be careful out there...

What does |= (single pipe equal) and &=(single ampersand equal) mean
...
I think you want to use a XOR instead of an AND for this.

Calculate last day of month in JavaScript
...0 : 31 days
That means you can shift the value 3 places with >> 3, XOR the bits with the original ^ m and see if the result is 1 or 0 in bit position 0 using & 1. Note: It turns out + is slightly faster than XOR (^) and (m >> 3) + m gives the same result in bit 0.
