strip

在nginx官方wiki的第三方模块中看到nginx strip模块,简单的看下功能，大意就是把网页中的空格，tab，换行删除以用来减少文件的大小，提高用户的访问速度，这个模块配合gzip效果更佳. mod_strip模块简介： 直接翻译官方的简介，mod_strip移除html文档中没必要的空行（包含空格，tab，换行）. mod_strip配合NginxHttpGzipModule来使用可以更好的减少文件大小以及减少页面下载时间,这个软件目前还在测试阶段，但是我用 得非常OK.mod_strip速度非常快,而且仅仅需要非常少量的内存. 1. mod_strip安装： # cd /usr/local/src/ # wget http://wiki.nginx.org/images/6/63/Mod_strip-0.1.tar.gz # tar -xzvf Mod_strip-0.1.tar.gz # cd nginx-1.4.2 //提前解压好的nginx # ./configure --prefix=/usr/local/nginx-1.4.2 --add-module=../mod_strip # make # make install 2. mod_strip简单用法： location / { strip on; } strip指令： 语法: strip on|off

Based on some experiments, it appears to me that the following Python v2.7 code: def lookup_pattern(pattern, file_containing_patterns): for line in file_containing_patterns: splits = line.split() if splits: if (pattern == splits[0]): return map(lambda x: x.strip(), splits[1:]) return None Could be simplified as follows to drop the map of strip() : def lookup_pattern(pattern, file_containing_patterns): for line in file_containing_patterns: splits = line.split() if splits: if (pattern == splits[0]): return splits[1:] return None I believe this is true because the split() should remove all white

isEmpty public static boolean isEmpty(CharSequence cs) 常用函数之一，判断字符串是否为""或者null StringUtils.isEmpty(null) = true StringUtils.isEmpty("") = true StringUtils.isEmpty(" ") = false StringUtils.isEmpty("bob") = false StringUtils.isEmpty(" bob ") = false isNotEmpty public static boolean isNotEmpty(CharSequence cs) 最常用函数之一，跟上面方法相对 StringUtils.isNotEmpty(null) = false StringUtils.isNotEmpty("") = false StringUtils.isNotEmpty(" ") = true StringUtils.isNotEmpty("bob") = true StringUtils.isNotEmpty(" bob ") = true isAnyEmpty public static boolean isAnyEmpty(CharSequence... css) 任意一个参数为空的话，返回true，

刚在看自定义 View 的知识点时，突然想起来，如果 CardView 宽高相等， CardView 设置圆角的半径为宽高的一半时，不就是一个圆形嘛？！ Cardview配合ImageView显示圆形图 1.布局文件 <android.support.v7.widget.CardView android:id="@+id/cv_img_activity" android:layout_width="200dp" android:layout_height="200dp" app:cardCornerRadius="100dp" app:cardElevation="10dp" app:cardPreventCornerOverlap="true"> <ImageView android:id="@+id/iv_cv_img_activity" android:layout_width="match_parent" android:layout_height="match_parent" android:scaleType="centerCrop"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:textColor="@color
