We usually think of types as something that can define a single layer of an object: with an interface we normally specify a list of a few properties and their respective types. If any one of those properties is another object we must refer again to i…

"I worked up a full implementation as well but I decided that it was too complicated to post in the blog. What I was really trying to get across was that immutable data structures were possible and not that hard; a full-on finger tree implementation…

refer:http://research.swtch.com/interfaces Go Data Structures: Interfaces Posted on Tuesday, December 1, 2009.   Go's interfaces—static, checked at compile time, dynamic when asked for—are, for me, the most exciting part of Go from a language design…

What is a high-performance data structure? To answer that question, we're used to applying normal considerations like Big-Oh complexity, and memory overhead, locality, and traversal order. All of those apply to both sequential and concurrent software…

一个星期前,我写了关于SQL Server里闩锁(Latches)和自旋锁(Spinlocks)的文章.2个同步原语(synchronization primitives)是用来保护SQL Server里的共享数据结构,例如缓存池里的页(通过闩锁(Latches)),锁管理器哈希表里的锁(通过自旋锁(Spinlock)).接下里你会看到越来越多的全新同步原语(synchronization primitives),即所谓的无锁数据结构(Lock-Free Data Structures).那也是…

Computer Science An Overview _J. Glenn Brookshear _11th Edition We have seen that the way data structures are actually stored in a computer's memory is not the same as the conceptual structure envisioned by the user. A two-dimensional homogeneous arr…

  Data structures A data structure is a group of data elements grouped together under one name. These data elements, known asmembers, can have different types and different lengths. Data structures can be declared in C++ using the following syntax: s…

To demonstrate the difference between mutability and immutability, imagine taking a drink from a glass of water. If our glass is mutable, when we take a drink, we retain the same glass and change the amount of water in that glass. However, if our gla…
