Though there is not an official Rack spec for asynchronous responses, Rack servers such as Rainbows! and Thin provide an asynchronous interface for responses that may happen at an unknown time in the future, such as in a web chat room.</p><p><a href="http://polycrystal.org/2012/04/15/asynchronous_responses_in_rack.html">Read more...</a></p> rack ruby Sun, 15 Apr 2012 23:58:00 GMT tag:polycrystal.org,2012-04-15:default/1334534280000 2012-04-15T23:58:00Z http://polycrystal.org/2012/03/07/bundler_searches_an_np_complete_problem.html The dependency resolution algorithm used in bundler (up to at least version 1.1) attempts an exhaustive search (using backtracking or backjumping) of what is an NP-complete problem. In most cases, a solution is found quickly. But in some real-world cases, the solution is not found quickly, and bundler appears to have hung.<p><a href="http://polycrystal.org/2012/03/07/bundler_searches_an_np_complete_problem.html">Read more...</a></p> bundler dependencies ruby Thu, 08 Mar 2012 02:52:00 GMT tag:polycrystal.org,2012-03-08:default/1331175120000 2012-03-08T02:52:00Z http://polycrystal.org/2012/02/26/deploying_sonar_to_jboss_as7.html <a href="http://www.sonarsource.org/">Sonar</a> does not officially support the <a href="http://www.jboss.org/as7">JBoss AS7</a> application server / servlet container (or any JBoss version). By default, JBoss's JPA modules notice the <code>persistence.xml</code> file in <code>sonar-core-2.13.1.jar!/META-INF/persistence.xml</code> and attempt to setup JPA (Hibernate). This fails (because Sonar isn't expecting JBoss to be doing anything in the way of setting up Hibernate). One solution is to remove the JPA module from JBoss.<p><a href="http://polycrystal.org/2012/02/26/deploying_sonar_to_jboss_as7.html">Read more...</a></p> java jboss sonar Mon, 27 Feb 2012 00:21:00 GMT tag:polycrystal.org,2012-02-27:default/1330302060000 2012-02-27T00:21:00Z http://polycrystal.org/2010/04/10/example_jruby_extension_in_java.html <p>Simple example of writing a JRuby extension in Java.</p><p><a href="http://polycrystal.org/2010/04/10/example_jruby_extension_in_java.html">Read more...</a></p> java jruby ruby Sat, 10 Apr 2010 14:34:00 GMT tag:polycrystal.org,2010-04-10:default/1270910040000 2010-04-10T14:34:00Z
