Yahoo Patent Letter to Facebook Referring to Memcached and Other Open Source Technologies

Sarah Lacy:

The technologies in question include things like memcached which was created in 2003 by LiveJournal and has been used longer than Facebook has been alive.[…]

Other examples include Open Compute, an open hardware project started by Facebook that focuses on low-cost, energy efficient server and data center hardware; Tornado a Python-based web server used for building real-time Web services; and HPHP, a source code transformer that turns PHP into C++.

I have no other details about this patent letter Yahoo sent Facebook, but I seriously doubt it targets these technologies separately. Most probably it refers to some sort of combinations of these and one that Facebook has mentioned as part of their IP.

Asyncdynamo: Amazon DynamoDB Async Python Library by Bitly

Bitly’s new asynchronous Amazon DynamoDB Python client:

Asyncdynamo requires Boto and Tornado to be installed, and must be run with Python 2.7. It replaces Boto’s synchronous calls to Dynamo and to Amazon STS (to retrieve session tokens) with non-blocking Tornado calls. For the end user its interface seeks to mimic that of Boto Layer1, with each method now requiring an additional callback parameter.

Available on GitHub.

Tornado Sees Some NoSQL Activity

Tornado, the non-blocking web server and tools open sourced by FriendFeed before their acquisition, seems to get some NoSQL activity. While Django is leading the way in the Python world, judging by the NoSQL projects happening around Node.js, one could say that Tornado, with its non-blocking architecture, may be an interesting alternative.

Thomas Pelletier has ☞ a blog post about a simple websocket + Tornado + Redis Pub/Sub protocol integration:

The principle is very simple: when your user loads the page, she is automatically added to a list of “listeners”. An independent thread is running: it listens for messages from Redis with the subscribe command, and send a message through Websocket to every registered ”listener”. In this example, the user can send a message to herself with a simple AJAX-powered form, which calls a view with a payload (the message), and the view publish it via the publish command of Redis.

This is basically a web chat! If you want to have fun, you can then add a roster, with a presence system, authentication etc…

There’s also a ☞ GitHub project called Trombi:

Trombi is an asynchronous CouchDB client for Tornado.

And I’m pretty sure there are other projects I’ve missed (but you can leave a comment to add them to the list).
