NOTE: This was a great hack in days gone by, but now both Apple and Google have improved their support for custom protocol handlers. Licensed under the WFTPL http://www.wtfpl.net/txt/copying/

A face-detection script in Python

This face-boxer.py script is more-or-less the same code that you'll find in the OpenCV tutorial: Face Detection using Haar Cascades. For another variation, with more explanation, check out RealPython's tutorial.

Usage

The face-boxer.py script is designed to be run from the command-line. It has two required arugments:

  1. The path to a XML file containing a Haar-cascade of visual features. In this example, it will be the features that make up a face.
  2. The path to an image file that you want to perform face-detection on. You can pass in more than one image file as space-separated arguments.

备份/恢复 Meteor 的 MongoDB 数据库

准备工作：

  1. 安装 Meteor。
  2. 安装 Homebrew，是为了更方便地安装 MongoDB。
  3. 安装 MongoDB，是为了使用里面的 mongodump 和 mongorestore。

备份与恢复本地数据库 (localhost)：

  1. 在想要备份的应用目录下，meteor run。
  2. 还是在相应的应用目录下，meteor mongo，查看相应的端口号，比如：如果显示的是 connecting to: 127.0.0.1:3001/meteor，那么端口号就是3001，下一步要用到。
