介绍KVM,它的本质以及如何配置和安装。虚拟化最近几年取得了长足的进步,首先由于有大量的开源虚拟机管理程序在不断发展,这个改进几乎排除了操 作系统与大功率服务器快速增长的利用之间的障碍,公司立即受益。知道最近,软件仿真虚拟化一直是关注的焦点,两个常见的软件仿真虚拟化途径是完全虚拟化和 半虚拟化。对于完全虚拟化,通常调用管理程序或虚拟机监视器,存在于虚拟操作系统和硬件层之间,这个层在操作系统实例之间多路复用竞争系统资源。半虚拟化 不同,管理程序在一个协作的环境中运作,因为每个客户操作系统都知道它正运行在一个虚拟化环境中,因此每个使用管理程序的协作都在硬件下完成虚拟。
在异步应用程序中发送和接收信息时,可以选择以纯文本和 XML 作为数据格式。掌握 Ajax 的这一期讨论另一种有用的数据格式 JavaScript Object Notation(JSON),以及如何使用它更轻松地在应用程序中移动数据和对象。

Dindel is a program for calling small indels from next-generation sequence data by realigning reads tocandidate haplotypes. The simplest use of Dindel is to consider all in indels in a read-alignment file(a BAM file), and to test whether each of these is a real indel or a sequencing error or mapping error.Dindel can also test candidate indels or sequence variants from other sources, e.g. a database of knownvariants, or indels called on a different sample for which you want to know if it is also supported by readsin your current sample.
MicroStrategy SDK是一个丰富的软件开发包( SoftwareDevelopment Kit),它把MicroStrategy平台功能很容易地集成到应用系统中
在新批次开发之前,必须新建对应eclipse工作空间,且工作空间名称必须与svn保持一致。下载代码时一定要仔细检查,确保导入的代码是本批次开发工作空间的代码。
软件危机及软件工程的出现速度是企业竞争致胜的关键因素,软件项目的最大挑战在于一方面要应付变动中的需求一方面要在紧缩的时程内完成项目传统的软件工程难以满足这些要求所以软件团队除了在技术上必须日益精进,更需要运用有效的开发流程,以确保团队能够发挥综效。这正是Agile Process (敏捷的软件开发流程)于近年来兴起的主要原因。
过去的 20 年里,各公司一直致力于开发自动化操作软件。一直以来,通过软件应用程序,我们获得了巨大的效率和生产力,而软件应用程序已成为一种在全球经济中进行协作和共享信息的新介质。实际上,使用软件应用程序已成为共享关键业务信息和处理各类事务的主要方式。今天,软件应用程序已涵盖了从电子邮件到用于事务处理的 CRM 等业务。
This book was born of frustration. We were each involved in a large project with a lotof event-based logic. Petty problems regularly turned into long days of debugging.
We would like to introduce Gradle to you, a build system that we think is a quantum leap for build technologyin the Java (JVM) world. Gradle provides:A very flexible general purpose build tool like Ant.Switchable, build-by-convention frameworks a la Maven. But we never lock you in!Very powerful support for multi-project builds.Very powerful dependency management (based on Apache Ivy).Full support for your existing Maven or Ivy repository infrastructure.Support for transitive dependency management without the need for remote repositories or pom.xml and ivy.xmlfiles.Ant tasks and builds as first class citizens.Groovy build scripts.A rich domain model for describing your build.
Dubbo 管控台可以对注册到 zookeeper 注册中心的服务或服务消费者进行管理,但管控台是否正常对 Dubbo 服务没有影响,管控台也不需要高可用,因此可以单节点部署。
Hibernate是一种orm 工具,O(object是Java中的对象)、R(relation是关系——关系型数据库中的数据)、M(mapping是映射),将数据库中的数据和内存中的Java的面向对象的数据进行数据之间的映射的工具。
VCS® is a high-performance, high-capacity Verilog® simulator thatincorporates advanced, high-level abstraction verificationtechnologies into a single open native platform.VCS is a compiled code simulator. It enables you to analyze,compile, and simulate Verilog, SystemVerilog, OpenVera andSystemC design descriptions. It also provides you with a set ofsimulation and debugging features to validate your design. Thesefeatures provide capabilities for source-level debugging andsimulation result viewing.
前端领域最近几年发展的特别迅速,可以说是百家争鸣。在底层的前端框架领域中,最早是jquery称霸互联网,近两年MVVM类型的框架慢慢成为主流,Vue、React和Angular三大框架并驾齐驱。可以说,目前这四种是开发者用的最多使用最广的底层框架,也由此衍生了大量基于这些框架的免费UI库。
CruiseControl是一个针对持续构建程序(项目持续集成)的框架,它包括一个email通知的插件,Ant和各种各样的版本管理工具。CruiseControl提供了一个Web接口, 可随时查看当前的编译状况和历史状况,一下简称CC

A relationship, in the context of databases, is a situation that exists between tworelational database tables when one table has a foreign key that references the primarykey of the other table. Relationships allow relational databases to split and store data invarious tables, while linking disparate data items. For example, if we want to storeinformation about a Customer and his Order, then we need to create two tables, onefor the Customer and another for the Order. Both tables, Customer and Order, willhave the relationship one-to-many so whenever we retrieve all orders of a customer,then we can easily retrieve them.

This is the second edition of the highly rated book Object-Oriented JavaScript byStoyan Stefanov, Packt Publishing. After the release of the first edition, in the lastfive years, JavaScript has moved from being mostly used in browsers for client-sidetechnologies to being used even on server side. This edition explores the “languageside“ of JavaScript. The stress is on the standards part of the language. The booktalks about ECMA Script, Object-Oriented JS, patterns, prototypal inheritance,and design patterns.
