r25888: {website} Dropping task priority and alphabetising It has always irked (website/trunk/getinvolved/en)

Author: atagar Date: 2012-11-14 06:26:37 +0000 (Wed, 14 Nov 2012) New Revision: 25888 Modified: website/trunk/getinvolved/en/volunteer.wml Log: Dropping task priority and alphabetising It has always irked me that we had a task 'priority'.

There are more <a href="https://metrics.torproject.org/formats.html">descriptor types</a> that we'd like to include in the search. The search application should handle most of them and understand some semantics like what's a timestamp, what's an IP address, and what's a link to another descriptor. Users should then be able to search for arbitrary strings or limit their search to given time periods or IP address ranges. Descriptors that reference other descriptors should contain links, and descriptors should be able to say from where they are linked. The goal is to make the archive easily browsable. - - The search application shall be separate from the metrics website and shouldn't rely on the metrics website codebase. The search application will contain hourly updated descriptor data from the metrics website via rsync. Programming language and database system are not specified yet, though there's a slight preference for Python/Django and Postgres for maintenance reasons.
