Read more.

So you have a ton of data that you need to search efficiently. How do you do it? Make friends with search. Index and search solutions can provide distinct advantages over traditional RDBMS systems for storing and querying large data sets. Learn how to leverage elasticsearch, an open source search solution, for fast and painless indexing and querying of data. Read more.

Illustrated guide to how to write non-blocking code for Perl (and some Javascript). Goal for this session is to give some familiarity to high-level non-blocking APIs for engineers who want to dig into non-blocking programming. Read more.

The Department of Veterans Affairs spawned in July 2011 the creation of OSEHRA, a non-profit organization whose mission is to apply best practices of open source software development to the improvement and maintenance of Open Source EHR information systems that are freely available for all.
