The problems with ACID, and how to fix them without going NoSQL
The problems with ACID, and how to fix them without going NoSQL (This post is coauthored by Alexander Thomson and Daniel Abadi) It is a poorly kept secret that NoSQL is not really about eliminating SQL from database systems (e.g., see these links). Rather, systems such as Bigtable, HBase, Hypertable, Cassandra, Dynamo, SimpleDB (and a host of other key-value stores), PNUTS/Sherpa, etc. are mostly

Prefix code - Wikipedia
A prefix code is a type of code system distinguished by its possession of the "prefix property", which requires that there is no whole code word in the system that is a prefix (initial segment) of any other code word in the system. It is trivially true for fixed-length codes, so only a point of consideration for variable-length codes. For example, a code with code {9, 55} has the prefix property;
