Computer Systems A Programmer's Perspective Second Edition To this point in our study of computer systems, we have assumed thatprograms run in isolation, with minimal input and output. How-ever, in the real world, application programs use services pr…

Profiling Go Programs  分析go语言项目 24 June 2011 At Scala Days 2011, Robert Hundt presented a paper titled Loop Recognition in C++/Java/Go/Scala. The paper implemented a specific loop finding algorithm, such as you might use in a flow analysis pass of a…

Data structures are a basic element in programming. Almost every program uses one or more types of data structures to store and manage their data. Java API provides the Java Collections framework that contains interfaces, classes, and algorithms, whi…

java.util.concurrent包的类都来自于JSR-166:Concurrent Utilities,官方的描述叫做“The JSR proposes a set of medium-level utilities that provide functionality commonly needed in concurrent programs. ”.作者是大名鼎鼎的Doug Lea,这个包的前身可以在这里找到,它最好的文档就是系统的API手册. 当然,这里参考的concurrent包…
