I am working on a little twitter project that uses twitter4r as the client API. As of recently twitter pulled some strings on their API and broke compatibility. syris:~ victori$ ruby somebot.rb /opt/local/lib/ruby/gems/1.8/gems/mbbx6spp-twitter4r-0.4.0/lib/twitter/client/base.rb:43:in `raise_rest_error’: Not Found (Twitter::RESTError) from /opt/local/lib/ruby/gems/1.8/gems/mbbx6spp-twitter4r-0.4.0/lib/twitter/client/base.rb:48:in `handle_rest_response’ from /opt/local/lib/ruby/gems/1.8/gems/mbbx6spp-twitter4r-0.4.0/lib/twitter/client/base.rb:20:in `http_connect’ from /opt/local/lib/ruby/1.8/net/http.rb:543:in `start’ from /opt/local/lib/ruby/gems/1.8/gems/mbbx6spp-twitter4r-0.4.0/lib/twitter/client/base.rb:16:in `http_connect’ from /opt/local/lib/ruby/gems/1.8/gems/mbbx6spp-twitter4r-0.4.0/lib/twitter/client/user.rb:37:in `user’ from somebot.rb:5 Curse […]

I finally got around to open sourcing our scala memcached implementation that we use at fabulously40 for session storage. Since wicket sessions can vary greatly in size, using the standard memcached server implementation became impractical due to the slab allocator. The current code on github lacks the ehcache store and an Actor IoHandler adapter. The […]

One of the first few things I have tackled while creating fabulously40 was stateless pagination. I wanted to keep all the public facing pages stateless to avoid session overhead. Wicket makes pagination brain dead simple at the cost of session use. I wanted to keep the simple programming model yet be completely stateless. Here is […]

I am about to run out the house for the Labor Day weekend, quickie post on my new coding url strategy. MixedParamHybridUrlCodingStrategy lets you keep stateful multi-pagemap URLs clean while using mixed parameters. Example… mount(new MixedParamHybridUrlCodingStrategy(“/questions”,QuestionsPage.class,false,new String[]{“cat”})); This will mount “/questions/stupid-category” and convert it to… new PageParameters(“cat”,”stupid-category”); package com.base.target.coding; import java.util.HashSet; import java.util.Iterator; import java.util.Map; […]

This is a late night post, so I am just going to make it short. This patch lets you use QueuedThreadPool with the Grizzly Connector. This is a monkey patch, getMaxThreads() should be moved up into the Thread Interface. — GrizzlyConnection-old.java Sat May 2 01:08:02 2009 +++ GrizzlyConnector.java Sat May 2 00:56:37 2009 @@ -51,6 […]

You might find this plugin nifty if you have multiple application servers processing requests. The Perlbal BackendHeaders plugin appends X-Backend headers with which backend served the request.

Try this fun perl benchmark, to test your dual core, SMP or hyperthreaded system. Before running, make sure you have perl 5.8 with threading support compiled in. Perl has native ithreads as of perl 5.8. #!/usr/bin/perl -w use threads; use strict; my $y1=Bench->new(); print “Bencmarking multi-threadedn”; $y1->benchmark(); print “Benchmarking single-threadedn”; $y1->ncpu(1); $y1->benchmark(); package Bench; sub […]

Dynamic type languages such as Perl, Ruby, PHP, and Python free you as the developer from managing memory in your application. However, it isn’t a fool proof solution that you won’t have memory leaks in your application. You as the developer should be aware of how the underlying garbage collector of your preferred language works […]

I *really* needed session affinity for our wicket application. HAproxy does session affinity but can’t be reconfigured at runtime without a restart. Perlbal is much more configurable, it lets you add and remove nodes in a pool at runtime. This makes deploying a new version of our web application a lot easier. I have the […]
