这篇也是组内分享的文档，整理了之前两篇Netty+Redis的文章，加入了一些Redis调优相关的命令和内容。 TCP连接Redis协议基于TCP/IP协议，受限于TCP连接建立的速度（三次握手等），及网络中数据传输的速度。 数据包大小Redis官方的一项测试显示，对于1k~10k以下的数据，Redis的吞吐量变化并不明显，吞吐量曲线在1k~10k左右出现拐点，如下图。 单线程Redis服务器为C语言编写，使用异步非阻塞IO，目前坚持使用单线程（可能出于线程锁的效率考虑）。对于高并发访问+多核CPU场景而言，并不能充分使用CPU资源，可能发生某核心占用率很高，其他核心空闲，但Redis请求阻塞在队列中的情况。搭建Redis集群可以解决该问题，但集群节点间访问引起的网络IO延时又带来新的问题。 Redis性能监控/测试info命令redis-cli中输入info可以显示当前Redis服务器的全部状态信息。这些信息按照内容被分成了很多部分，可以用额外的参数来单独获取，如下： 参数名 说明 server 获取 server 信息，包括 version, OS, port 等信息 ...

这是我与同学组队在2017年2月参加美国数学建模大赛（Interdisciplinary Contest In Modeling ）的文章，比赛题目为：Sustainable Cities Needed 题目原文为： Background:Many communities are implementing smart growth initiatives in an effort to consider long range, sustainable planning goals. “Smart growth is about helping every town and city become a more economically prosperous, socially equitable, and environmentally sustainable place to live.”[2] Smart growth focuses on building cities that embrace the E’s of sustainability—Economical ...

Recently I am thinking about the question in the title: What is the difference between valuation and pricing? And the purpose of them? I search over Google to get the result and find few interesting response. The one I think solve my confuse most is: 估值模型的原理是现金流量折现，或者用同类型的公司进行对比 资产定价模型是根据风险收益对等的原则计算股票的收益率 前者算出的是绝对价值，后者算出的相对价值 两者都是对价值的估计 Though here the author talks about CAPM rather than general pricing, but it still works. From my understanding, pricing is replicate or construct the derivative ...

Equations are given in the format A / B = k, where A and B are variables represented as strings, and k is a real number (floating point number). Given some queries, return the answers. If the answer does not exist, return -1.0.Example:Given a / b = 2.0, b / c = 3.0.queries are: a / c = ?, b / a = ?, a / e = ?, a / a = ?, x / x = ? .return [6.0, 0.5, -1.0, 1.0, -1.0 ]. The input is: vector<pair<string, string>> equations, vector& values, vector<pair<string, string>> q ...

她可以褪色，可以枯萎，怎样都可以，但只要我看她一眼，万般柔情便涌上心头。

Evaluate the value of an arithmetic expression in Reverse Polish Notation. Valid operators are +, -, *, /. Each operand may be an integer or another expression. Note: Division between two integers should truncate toward zero. The given RPN expression is always valid. That means the expression would always evaluate to a result and there won’t be any divide by zero operation. Example 1: 123Input: ["2", "1", "+", "3", "*"]Output: 9Explanation: ((2 + 1) * 3) ...

编辑人：酷酷的诚 邮箱：zhangchengk@foxmail.com 内容： # 描述 该处理器根据流文件的内容计算一个或多个JsonPath表达式。这些表达式的结果被写入到FlowFile属性，或者写入到FlowFile本身的内容中，这取决于处理器的配置。通过添加用户自定义的属性来输入jsonpath，添加的属性的名称映射到输出流中的属性名称(如果目标是flowfile-attribute;否则，属性名将被忽略)。属性的值必须是有效的JsonPath表达式。“auto-detect”的返回类型将根据配置的目标进行确定。当“Destination”被设置为“flowfile-attribute”时，将使用“scalar”的返回类型。当“Destination”被设置为“flowfile-content”时，将使用“JSON”返回类型。如果JsonPath计算为JSON数组或JSON对象，并且返回类型设置为“scalar”，则流文件将不进行修改，并将路由到失败。如果所提供的JsonPath计算为指定的值，JSON的返回类型可以返回“scalar”。如果目标是“flowfile-c ...
