What's the best way to validate an XML file against an XSD file?
... is basically the same as the accepted answer. This solution seems to me a bit inefficient though, as it unnecessarily builds the DOM for the xml to parse: parser.parse(new File("instance.xml")). The validator accepts a Source, so you can: validator.validate(new StreamSource(new File("instance.xml")...
Best Practices: Salting & peppering passwords?
... purely theoretical, it's in fact not. For example, Bcrypt cannot accept arbitrary passwords. So passing bcrypt(hash(pw), salt) can indeed result in a far weaker hash than bcrypt(pw, salt) if hash() returns a binary string.
Working Against Design
The way bcrypt (and other password hashing algorithm...
How do you dynamically add elements to a ListView on Android?
...tion might be to create unnamed List object in Adapter than to create a 16 bit pointer to an list object. Which is not needed after creating the adapter because adapter has an add method.

Advantages of stateless programming?
... of interactions it can have with the rest of the program.
That's the big win from 'immutability' IMO. In an ideal world, we'd all design terrific APIs and even when things were mutable, effects would be local and well-documented and 'unexpected' interactions would be kept to a minimum. In the re...

Concept of void pointer in C programming
...e must be aligned at boundary of the size of data type (e.g. pointer to 32-bit integer must be aligned at 4-byte boundary to be dereferenced).
For example, reading uint16_t from void*:
/* may receive wrong value if ptr is not 2-byte aligned */
uint16_t value = *(uint16_t*)ptr;
/* portable way of r...
Merge two Git repositories without breaking file history

One quick bit of knowledge before I move forward, EBCDIC is another character set, similar to ASCII, but a total competitor. PHP attempts to deal with both. But basically, this means byte EBCDIC 0x4c byte isn't the L in ASCII, it's act...
Heap vs Binary Search Tree (BST)
...e, O(n log(n)) for BST.
Advantage of BST over binary heap
search for arbitrary elements is O(log(n)). This is the killer feature of BSTs.
For heap, it is O(n) in general, except for the largest element which is O(1).
"False" advantage of heap over BST
heap is O(1) to find max, BST O(log(n)...

All great answers, but this wins for conciseness, with great short-circuiting. Thanks all!
