在 Xcode 里下载文件真的是一种折磨, 特别是每次 Xcode 大版本更新都会遇到新的下载内容. 经过一翻周折, 本人找到一个方法可以轻松快速便捷地下载和安装对应的 Simulator 和 Doc 文件

1. 在 Mac 下, 打开 Xcode, 进入 Preference 中的 Downloads 面板
2. 点击任意的下载按钮
3. 打开系统帮助工具 Console
4. 稍等一会儿, 在 Xcode 里取消下载, 然后你会在 Console 里面看到对应的下载地址 (对应的 Cosnole Message 是 (DVTDownloadable: Download Cancelled. Downloadable: ...) 之类的)
5. 复制对应的链接地址, 到某雷或者任何比 Xcode 下载快的工具里
6. 等待下载完成, 进入 /Users/#{Username}/Library/Caches

Autofs on Mac OS X

With autofs you can easily mount network volumes upon first access to the folder where you want to mount the volume. Autofs is available for many OS and is preinstalled on Mac OS X so I show you how I mounted my iTunes library folder using this method.

Prepare autofs to use a separate configuration file

autofs needs to be configured so that it knows where to gets its configuration. Edit the file /etc/auto_master and add the last line:

#
# Automounter master map
#

+auto_master # Use directory service

libdispatch efficiency tips

The libdispatch is one of the most misused API due to the way it was presented to us when it was introduced and for many years after that, and due to the confusing documentation and API. This page is a compilation of important things to know if you're going to use this library. Many references are available at the end of this document pointing to comments from Apple's very own libdispatch maintainer (Pierre Habouzit).

My take-aways are:

• You should create very few, long-lived, well-defined queues. These queues should be seen as execution contexts in your program (gui, background work, ...) that benefit from executing in parallel. An important thing to note is that if these queues are all active at once, you will get as many threads running. In most apps, you probably do not need to create more than 3 or 4 queues.

• Go serial first, and as you find performance bottle necks, measure why, and if concurrency helps, apply with care, always validating under system pressure. Reuse
