MOSS 2007 入门 : 站点定义和站点模板

在WSS中有两种方式可以实现对站点的定制：站点定义和站点模板。无论是一个站点定义还是一个站点模板都可以包含对一个WSS站点的定义：其中包括站点的列表、文件、Webpart、feature和设置。模板实际上是包括站点模板和列表模板，当用户通过Web界面或是SharePointDesigner更改一个站点或是列表的定义时，模板中仅仅记录了更改的内容而并没有包含全部定义。一个标准的自定义模板中实际上是引用了其原始的站点定义，所以当一个站点模板部署到一个新的站点上

Solr(5.1.0) 与Tomcat 从0开始安装与配置

1、什么是Solr？Solr是一个基于Lucene的Java搜索引擎服务器。Solr提供了层面搜索、命中醒目显示并且支持多种输出格式（包括XML/XSLT和JSON格式）。它易于安装和配置，而且附带了一个基于HTTP的管理界面。Solr已经在众多大型的网站中使用，较为成熟和稳定。Solr包装并扩展了Lucene，所以Solr的基本上沿用了Lucene的相关术语。更重要的是，Solr创建的索引与Lucene搜索引擎库完全兼容。通过对Solr进行适当的配置，某

Python

python3实现二叉树的遍历与递归算法解析(小结)

1、二叉树的三种遍历方式二叉树有三种遍历方式：先序遍历，中序遍历，后续遍历即：先中后指的是访问根节点的顺序eg:先序根左右中序左根右后序左右根遍历总体思路：将树分成最小的子树，然后按照顺序输出1.1先序遍历a先访问根节点b访问左节点c访问右节点a（b(d(h))(e(i))）(c(f)(g))--abdheicfg1.2中序遍历a先访问左节点b访问根节点c访问右节点(((h)d)b((i)e))a((f)c(g))--hdbieafcg1.3后序遍历a先访

Backbone vs Ext JS 4 MVC

导读最近一段时间，我在研究移动WebApp应用开发，想在设计WebApp前端JS构架时，使用MVC分层技术，经过一段时间的技术选型，最终确定使用BackboneJS作为底层基础MVC框架。在使用Backbone写示例时，总是觉得非常怪，但又说不出怪在哪，所以，就想通过Backbone与ExtJS4MVC的对比，来发现Backbone的缺点与优化点。PS：由于我在做Desktop前端JS开发时，十分青睐ExtJS这一类的框架，ExtJS4MVC是我认为在所有
