My presentation at JavaZone 2010, http://bit.ly/cO1AE5, shows how to do this with just a summing reducer and I admit I should probably write a new blog post about that.

The short answer is no. Search consists of data collection, creation of an index and ranking. Traditional data collection is done by crawlers following links. Obviously that’s not optimal for real-time search unless you treat oft-changing sites differ…

]]> Comment on OAuth and the 4 hour work day by knuthellan http://knuthellan.com/2009/06/05/oauth-and-the-4-hour-work-day/#comment-58 Fri, 04 Mar 2011 19:11:40 +0000 http://knuthellan.wordpress.com/?p=92#comment-58 The OAuth system included a login page implemented in haml and based on the haml template for the rest of the site. I stored all persistent data including request, access tokens and remote service credentials in CouchDB.

I did not add the user page to revoke access at the same time, but the basic support for that was included. Adding it meant another haml view and some basic sinatra post handling. This addition was probably a couple of days work.

Sticky sessions in the load balancer will avoid problems related to request tokens not being synchronized between database replicas in time.

1) user’s authorization via Login page.
2) did you store all the request/access tokens in db
3)Did it include a website for users to revoke access to apps when needed?

It was about two weeks later before the full request signing between PHP and Ruby was working. Since getting this right is important, I would set aside a week to ensure it’s well tested and robust.

]]> Comment on A functional approach to Ruby by MononcQc http://knuthellan.com/2010/06/22/a-functional-approach-to-ruby/#comment-39 Thu, 24 Jun 2010 15:37:47 +0000 http://knuthellan.com/?p=276#comment-39 Just a little technical point. Erlang isn’t a purely functional language, as it allows unrestrained side effects, message passing being the most obvious example of that.

You can have purely functional data structures and functions, but they only are because the programmer wanted it so — nothing coming from the language coerces you to do otherwise.
