PHP | 痴人说梦

http://www.riverlet.me/blog/archives/tag/php

依赖注入、控制反转这两个概念近期有点火，尤其是 Yii 2.0 框架推出后，更是在其官方文档里特别提到这一概念，感觉相当高大上。 Dependency injection is a software design pattern that allows the removal of hard-coded dependencies and makes it possible to change them, whether at run-time or compile-time. 译依赖注入是一个软件设计模式，它移除了硬编码依赖，使运行时或编译时的修改成为可能。 Php namespace Database;. Class Database { protected $adapter;. Public function construct() { $this- adapter = new MySqlAdapter; } }. Db = new Database();. Php namespace Database;.

Linux | 痴人说梦

http://www.riverlet.me/blog/archives/tag/linux

64位 Linux 下编译安装 aapt 的方法附下载地址. 今日要把一个旧的服务迁移到运行着64位CentOS的新服务器上，运行 aapt (APK 包解析工具) 时报错如下. Lib/ld-linux.so.2: bad ELF interpreter: No such file or directory. Yum whatprovides "*/ld-linux.so.2". 查询看哪个lib里面包含这个so文件，结果是需要 glibc-2.12-1.107.el6.i686，原来 aapt 是一个32位程序，无法直接运行在 64 位环境下。 Google了一下，网上大多数解决方案是 yum install xxx 库以满足 aapt 的32位环境，要运行这么个小工具还要额外安装一个库，即使安装了可能还依赖其他的库，太low，所以，先看看有没有其他办法。继续Google，发现官方并不提供64位的 aapt 工具，好在有热心网友已经把它重写并移植到 64 位环境下了，在这儿 https:/ code.google.com/p/android-sdk/ ，感谢该作者，帮了大忙。 Wget http...
