Fastest way to serialize and deserialize .NET objects
...cases where ProtoBuf and NetSerializer are well-suited to, but in terms of raw performance for at least relatively simple objects... BinaryFormatter is significantly more performant, by at least an order of magnitude.
YMMV.

How does @synchronized lock/unlock in Objective-C?

When should I use double instead of decimal?
...ven if it had to be padded out to 16 bytes; it would have allowed a larger range than double or Decimal, much better speed than Decimal, support for transcendental operations (e.g. sin(x), log(x), etc.), and precision which while not quite as good as Decimal would be way better than double.

Difference between a Seq and a List in Scala
...efined order of elements. Sequences provide a method apply() for indexing, ranging from 0 up to the length of the sequence. Seq has many subclasses including Queue, Range, List, Stack, and LinkedList.
A List is a Seq that is implemented as an immutable linked list. It's best used in cases with last...
Memcached vs. Redis? [closed]
