Hi everyone, I'm Chris Wanstrath.

When Jeremy asked me to come talk, I said yes.  Hell yes.  Immediately.  But
then I took a few moments and thought, Wait, why?  Why me?  What am I supposed
to say that's interesting?  Something about Ruby, perhaps.  Maybe the
future of it.  The future of something, at least.  That sounds
keynote-y.

Sublime Text 2 – Useful Shortcuts (Mac OS X)

General

⌘T	go to file
⌘⌃P	go to project
⌘R	go to methods
⌃G	go to line

These two files should help you to import passwords from mac OS X keychains to 1password.

Assumptions:
1) You have some experience with scripting/are a power-user. These scripts worked for me
   but they haven't been extensively tested and if they don't work, you're on your own!
   Please read this whole document before starting this process. If any of it seems
   incomprehensible/frightening/over your head please do not use these scripts. You will
   probably do something Very Bad and I wouldn't want that.
2) You have ruby 1.9.2 installed on your machine. This comes as standard with Lion, previous
   versions of OS X may have earlier versions of ruby, which *may* work, but then again, they

在导出数据之前，先设置两个值 max_allowed_packet 128M～256M或者更大，参考内存的使用量;net_buffer_length 一般设置成16384。在使用mysqldump导出数据的时候增加两个三个参数 -e --max_allowed_packet=128M --=net_buffer_length=16384

设置时区
ec2实例和国外vps默认的时区都是当地的，不适合国内使用，通过手动修改自己的时区

ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

date一下看看已经更改过来了

1. 连接 VPN Cisco IPSec (让系统生成配置文件)

3. 修改 racoon 配置文件:
   $ sudo vim /etc/racoon/racoon.conf
4. 将最后一行注释掉（目的是不使用系统生成配置）:
   # include "/var/run/racoon/*.conf" ;
5. 将下面一行添加到文件末尾，包含分号（使用定制的配置文件）:
