    This had a large performance penalty of between a factor 10 and 20 for Java versus C in average applications. [5] To combat this, a just-in-time (JIT) compiler was introduced into Java 1.1. Due to the high cost of compiling, an added system called HotSpot was introduced in Java 1.2 and was

  4. Error correction code - Wikipedia

    en.wikipedia.org/wiki/Error_correction_code

    Low-density parity-check (LDPC) codes are a class of highly efficient linear block codes made from many single parity check (SPC) codes. They can provide performance very close to the channel capacity (the theoretical maximum) using an iterated soft-decision decoding approach, at linear time complexity in terms of their block length.

    Weave merge was apparently used by the commercial revision control tool BitKeeper and can handle some of the problem cases where a three-way merge produces wrong or bad results. It is also one of the merge options of the GNU Bazaar revision control tool, and is used in Codeville. [citation needed]

    3: Replaying the game 7 vs 3 (previous loser). 3 wins because it is smaller. Therefore, 3 is promoted to the top while 7 is saved in the node. 4: Replaying the game 3 vs 2 (previous loser). 2 wins because it is smaller. Therefore, 2 is promoted to the top while 3 is saved in the node. 5: The new overall winner 2 is saved above the root.
