During the three-day training, the first day I found that the lecturer was a C ++ cool: Herb Sutter. The company spent more than 2000 yuan on a single person, and I felt that it was not very worthwhile, it can be regarded as learned. It will be useful in the future: Titled keep Itve concurrency Introduction and Overview 1.

extension of the result set that provides this mechanism. 游标是通过游标库来实现的。游标库是常常作为数据库系统或数据访问 API 的一部分而得以实现的软件， 用来管理从数据源返回的数据的属性（结果集）。这些属性包括并发管理、在结果集中的位置、返回的行数， 以及是否能够在结果集中向前和/或向后移动（可滚动性）。 游标跟踪结果集中的位置，并允许对结果集逐行执行多个操作，在这个过程中可能返回至原始表，也可能不返回至原始表。 换句话说，游标从概念上讲基于数据库的表返回结果集。 由于它指示结果集中的当前位置 ，就像计算机屏幕上的光标指示当前位置一样，“游标”由此得名。2, what is the function of the cursor?① Specifies the location of a particular row in the result set.② retrieves a row or successive rows based on the current result set location.③ modifie

A role framework for implementing Java concurrency Introduction: Concurrent programming is the core concept of Java™ Development 2.0, but it may not be thread-based concurrency. Andrew Glover explains why roles are better than threads in concurrent programming in multi-core systems. He then introduced kilim--, a role-based messaging framework combining concurrent programming and distributed programming. For software developers, debugging an indeterminate flaw in a multithreaded application is
