    curl -sSL -I \
        -H "Accept: application/vnd.docker.distribution.manifest.v2+json" \

go框架选择观点与分类

因为go的标准库net/http功能非常全，所以关于go语言的框架使用有三种观点:

1. 不用框架:

   因为go的标准库net/http功能非常全。只需要用一个完成路由和路由参数的库，加上海量的能满足任何需求(比如session什么的)的中间件就行了。目的是代码里始终使用net/http，保持最大的兼容性。不需要为了符合框架去写一些奇怪的shim程序。

2. 轻量级框架:

Ubuntu 16 default python is almost python 3

Loads of solutions exist, but for changing the system default, alias is not the way to go.

$ update-alternatives --list python update-alternatives: error: no alternatives for python

Fix iOS Project Swift Errors

In order to build the iOS app in the latest XCode, you need to convert the project to Swift 3.0. After you do this, when you try to run or archive the project, you will get a bunch of errors. This section explains how to fix them.

IMPORTANT NOTE: Fix all the RED errors. There will also be yellow triangles and the option to "update to recommended settings". Do NOT fix these things and do NOT update to recommended settings.

Info from Apple on what has changed in Swift: http://adcdownload.apple.com/Developer_Tools/Xcode_8_beta_6/Release_Notes_for_Xcode_8_beta_6.pdf ("New in Xcode 8 beta 6 - Swift Compiler" section on page 8)

"NSURL" is not implicitly convertible to "URL"
