What is a bus error?
...and then typecast for access to a problem mode (i.e. You set up an uint8_t array, add one, two, or three to the array's pointer and then typecast to a short, int, or long and try to access the offending result.) X86 systems will pretty much let you do this, albeit at a real performance penalty. SO...

Note that an effect of using this double brace initialisation is that you're creating anonymous inner classes. The created class has an implicit this pointer to the su...
Using Linq to get the last N elements of a collection?
...lem with most enumerables; in fact, optimizations exist already for Lists, Arrays, and even EF queries to evaluate the Count() operation in O(1) time.
If, however, you must use a forward-only enumerable and would like to avoid making two passes, consider a one-pass algorithm like Lasse V. Karlsen o...
Evenly distributing n points on a sphere
...
In this example code node[k] is just the kth node. You are generating an array N points and node[k] is the kth (from 0 to N-1). If that is all that is confusing you, hopefully you can use that now.
(in other words, k is an array of size N that is defined before the code fragment starts, and which...
