准备: | |
libxml2 2.6.18 or above from http://www.xmlsoft.org/ | |
libxslt 1.1.x or above from http://www.xmlsoft.org/ | |
先查看当前系统中是否有安装libxml2,libxslt这两个库,如果没有请到下面的网站中去下载安装 | |
# sudo apt-get install libxml2-dev | |
# sudo apt-get install libxslt1-dev | |
由于安装pgAdmin3需要wxGTK,所以也要下载wxGTK | |
wxGTK 2.8.x from http://www.wxwidgets.org/ |

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.
To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.
Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.
