Cassandra study Note 2

Here, we start to build a Cassandra cluster.I. Knowledge about Token Token is a very important concept in Cassandra. It is an attribute that Cassandra uses to balance the loads of nodes in the cluster. Cassandra has different token allocation policies. We recommend that you use the default randompartitioner partition p

Opencv experiences (1) The second chapter of learning opencv mainly introduces some common and interesting functions and data types, so that students at the beginning are more interested in image processing, although I do not understand the internal experiment of the function and the meaning of some defined constants, I am still very happy after learning Chapter 2. At least I know some basics of image processing, such as contour processing; Knowledge
