Tornado Web Server

Tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed. By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user. Upgrade notes As of Tornado 3.2, the backports.ssl_match_hostname package must be installed when running Tornado on Python 2. This will be installed automatically when using pip or easy_install. Hello, world Here is a simple “Hello, world” example web app for Tornado: import tornado.ioloop import tornado.web class MainHandler(tornado.web.RequestHandler): def get(self): self.write("Hello, world") application = tornado.web.Application([ (r"/", MainHandler), ]) if __name__ == "__main__": application.listen(8888) tornado.ioloop.IOLoop.instance().start() This example does not use any of Tornado’s asynchronous features; for that see this simple chat room.

Using PyObjC for Developing Cocoa Applications with Python Cocoa Frameworks The Cocoa frameworks consist of libraries, APIs, and runtimes that form the development layer for all of OS X. By developing with Cocoa, you will be creating applications the same way OS X itself is created. Your application will automatically inherit the great behaviors and appearances of OS X, with full access to the underlying power of the UNIX operating system. Using Cocoa with the Xcode IDE is simply the best way to create native Mac applications. The Power of Objective-C Twisted Twisted is an event-driven networking engine written in Python and licensed under the open source MIT license. Twisted makes it easy to implement custom network applications. Here's a TCP server that echoes back everything that's written to it:

Latent Semantic Analysis in Python Latent Semantic Analysis (LSA) is a mathematical method that tries to bring out latent relationships within a collection of documents. Rather than looking at each document isolated from the others it looks at all the documents as a whole and the terms within them to identify relationships. An example of LSA: Using a search engine search for “sand”.
