window pt-query-digest 如何使用

pt-query-digest简介使用

简介 pt-query-digest 是用于分析mysql慢查询的一个工具,与mysqldumpshow工具相比,py-query_digest 工具的分析结果更具体,更完善. 有时因为某些原因如权限不足等,无法在服务器上记录查询.这样的限制我们也常常碰到,所以开发了两种替代的技术,都集成到了Percona Toolkit 中的 pt-query-digest 中. 第一种是通过 --processlist 选项不断查看 SHOW FULL PROCESSLISTR 的输出,记录查

dojo事件驱动编程之事件绑定

什么是事件驱动? 事件驱动编程是以事件为第一驱动的编程模型,模块被动等待通知(notification),行为取决于外来的突发事件,是事件驱动的,符合事件驱动式编程(Event-Driven Programming,简称EDP)的模式. 何谓事件?通俗地说,它是已经发生的某种令人关注的事情.在软件中,它一般表现为一个程序的某些信息状态上的变化.基于事件驱动的系统一般提供两类的内建事件(built-in event):一类是底层事件(low-level event)或称原生事件(native ev

利用HTML实现软件的UI

先看看下面的实例这是应朋友之邀编写的查询职业技能鉴定考核的分数的软件.看过我之前的博文的,可知这是借用我之前的网页界面. 这个UI,如果用WinForm的控件来实现,难度很高. 于是另辟蹊径,用Webbrowser控件加载HTML网页来实现软件的UI. 这样做的好处有: 1.用HTML编写UI的难度要低得多,可以利用网上很多现成的UI库实现绚丽的UI.本例就是利用Bootstrap库实现的界面UI. 2.实现前端UI和后台逻辑的分离.前端UI(HTML)只实现界面的绘制(可以简单的对前端数据验

用R分析时间序列(time series)数据

时间序列(time series)是一系列有序的数据.通常是等时间间隔的采样数据.如果不是等间隔,则一般会标注每个数据点的时间刻度. time series data mining 主要包括decompose(分析数据的各个成分,例如趋势,周期性),prediction(预测未来的值),classification(对有序数据序列的feature提取与分类),clustering(相似数列聚类)等. 这篇文章主要讨论prediction(forecast,预测)问题. 即已知历史的数据,如何准确

QQ截图时窗口自动识别的原理（WindowFromPoint, ChildWindowFromPoint, ChildWindowFromPointEx,RealChildWindowFromPoint）

新版的QQ在截图时加入了窗口自动识别的功能,能根据鼠标的位置自动画出下面窗口的轮廓.今天有人在论坛上问起这个问题,下面我们来探讨这个功能的实现原理. 首先我们要明白截图软件的基本原理,截图时实际上是新建了一个全屏窗口,然后将当前桌面的截图画在上面,大部分截图软件,包括QQ都是这么做的.根据鼠标位置获取下层窗口,有好几个类似的API可以用(WindowFromPoint, ChildWindowFromPoint, ChildWindowFromPointEx,RealChildWindowFro

Android显示系统设计框架介绍

1. Linux内核提供了统一的framebuffer显示驱动,设备节点/dev/graphics/fb*或者/dev/fb*,以fb0表示第一个显示屏,当前实现中只用到了一个显示屏. 2. Android的HAL层提供了Gralloc,分为fb和gralloc两个设备.设备fb负责打开内核中的framebuffer以及提供post. setSwapInterval等操作,设备gralloc则负责管理帧缓冲区的分配和释放.上层只能通过Gralloc访问帧缓冲区,这样一来就实现了有序的封装保护.
