之前做过这样一个需求,要让商家页的商家图片按照图片外面box的大小等比例缩放.之前的想法是在页面中先输出图片的src,然后在页面底部初始化js,然后在js中写相应的可以使图片按照box的大小等比例缩放的函数.要实现图片的等比例缩放要做到以下几点, 第一,得到图片的width和height 第二,比较图片的width和height与box的width的height的大小,共有四种情况, # 如果图片的width和height均小于box的width和height,那么直接让图片上下左右居中即可,…

1 n-gram模型与auto complete n-gram模型是假设文本中一个词出现的概率只与它前面的N-1个词相关.auto complete的原理就是,根据用户输入的词,将后续出现概率较大的词组显示出来.因此我们可以基于n-gram模型来对用户的输入作预测. 我们的实现方法是:首先用mapreduce在offline对语料库中的数据进行n-gram建模,存到数据库中.然后用户在输入的时候向数据库中查询,获取之后出现的概率较大的词,通过前端php脚本刷新实时显示在界面上.如下所示: 2 m…

最近在看code complete,学习了一些东西,作为点滴,记录下来. 关于类: 类的接口抽象应该一致 类的接口要可编程,不要对类的使用者做过多的假设.不要出现类似于:A的输入量一定要大于多少小于多少,一定要在某个函数前call之类的限制,而应该在assert等地方加入这些判断,让代码去做限制,而不是注释. 代码阅读的次数要比写的次数多得多 类的成员变量表征类拥有怎样一个属性 类的继承表征类还可以有另一个特殊的版本 类用到的其他类的次数叫做扇入(fan in),越少越好 要在构造函数中对所有的…

重读code complete 说说代码质量 2014年的第一篇文章本来计划写些过去一年的总结和新年展望,但是因为还有一些事情要过一阵才能完成,所以姑且不谈这个,说说最近重读code complete 的收获吧. 记得第一次读code complete 还是刚毕业的时候,身边好多朋友极力向我推荐此书,于是我就买了一本读起来,可能是当时功力不够,读起来总是觉得没啥味道,而且极为枯燥,总觉得不如<深入浅出MFC>,<CLR Var C#>,<Windows Internals&g…

  在使用vmware的过程中发现创建快照.恢复快照.管理快照等功能突然都变成灰色的,用不了.更觉得夸张的是仅仅剩下关闭虚机按钮是红色的.心想估计是虚机快照没处理完之类的问题导致的,于是想想关闭虚机重启得了. 点击关闭之后提示"xxx is still busy. Please wait until the operation is complete before closing"(其中xxx是你虚机的名字). 记得N早以前遇到过,不过没有记录所以忘记怎么处理的,晕了吧,后悔偷懒没记录…

背景:本人在网上学习java时,看到一段样例代码比较好,因此复制粘贴到eclipse中看看编译结果.结果eclipse报"Syntax error, insert "}" to complete"错误.如下图所示: 经过查找,代码中没有缺少"}"号,也没有语法错误.再经常反复查找问题,终于发现导致报错的原因是在复制过程中,下图大括号前面的类似空格的不可见字符没有删除.把下图红线的空格删除后,报错就消失了.…

这题也是第二次做,本想第一次做时参考的算法会和老师讲的一样,不想老师讲的算法用在这题感觉还不如思雪园友的算法(http://www.cnblogs.com/sixue/archive/2015/04.html)来的简单,不过老师给的思路是一种挺通用的思路,可以用来解决一系列的问题,但我目前看着有点吃力.我坚持认为对全局变量的使用需十分谨慎,能不用就不用,所以为了不出现全局变量,就无辜多了一串参数.实现代码如下,题目在代码下方 #include <stdio.h> #include <st…
