With this gist, I, as a total assembly noob, am trying to understand the XCDUUID runtime hack (https://github.com/0xced/NSUUID/blob/1.0.1/NSUUID.m#L167-L221) to be able to use NSUUID on iOS < 6.0.
@implementation XCDUUID
+ (void) load
{
// query runtime if NSUUID class already exists, if so => done
if (objc_getClass("NSUUID"))
{
return;
}

mac os x:自动挂载ntfs硬盘为读写权限。 只要ntfs硬盘连接到电脑即可使用 ./ntfs_mount_auto.py 挂载ntfs磁盘为可读写,ntfs_unmount.py 为卸载磁盘。 ntfs_mount.py 是较早的版本,只有电脑先识别除硬盘,在/Volumes 可读到硬盘内容时才可以使用此脚本挂载为可读写。 建议使用./ntfs_mount_auto.py

为什么不应该用 SSL 翻墙

SSL 设计目标:

  1. 防内容篡改
  2. 防冒充服务器身份
  3. 加密通信内容

而翻墙的目标:

  1. 不被检测出客户端在访问什么网站
  2. 不被检测出服务器在提供翻墙服务

xcode 5 + OS X 10.9 mavericks GHC work around nuttiness

PSA :

just use GHC for OSX https://ghcformacosx.github.io

the rest of these directions are preserved for historical purposes

TLDR version, if you have homebrew

xcode-select --install ; brew tap homebrew/versions ;   brew tap homebrew/dupes \
