Knowing almost technical solutions

Know the whole http://www.aliyun.com/zixun/aggregation/11116.html "> The site map is as follows:

Knowing is rarely used in the development of a Web site in Python, but also a lot of places worth learning, from knowing we can also understand some of the new WEB technology.

First, the Python framework

Knowing the current use of the Tornado framework. Tornado Tornado Web Server, a Web server and Web application framework written in Python language, is used by FriendFeed in its own website FriendFeed. After being acquired by Facebook, the framework is open to the public as open source software.

Knowing to use Redis for caching, queuing, counting, or tasks, use Redis-Py to connect clients to it.

Eight, the message system

Knowing that the messaging system uses the comet implementation, comet is a "server push" technology based on a long http connection.

Nine, the virtual environment

As a Python site, it is very likely that Virtualenv will be the solution to the purely packet-based environment.

Ten, code deployment

The common Python project basically uses Fabric for deployment, and does not know which one to use.

Eleventh, search to achieve

Knowing the use mmseg do Chinese word segmentation, the corresponding root exists redis as the key, the database id as the value, each data item is a zset collection. Search according to the key to find the corresponding value.
