Bringing up search results

So... back to the idea of being your own Google. Why? Maybe because you need to provide search on an intranet of internal documents. Maybe because you want your site to offer its own search (after all, not everyone has figured out site:example.com search-terms, and many expect sites to have their own search widget). Maybe because you'd like to understand the reasoning behind the search results, or have a system where by results aren't purchased by advertisers.

And that's why we're talking about Nutch.

In today's Feature Article, Introduction to Nutch, Part 2: Searching, Tom White writes:

In this article, we turn to searching. The Nutch search system uses the index and segments generated during the crawling process to answer users' search queries. We shall see how to get the Nutch search application up and running, and how to customize and extend it for integration into an existing website. We'll also look at how to re-crawl sites to keep your index up to date--a requirement of all real-world search engines.


The Sun bloggers turn out en masse in today's Weblogs to comment on the beta release of Java SE 6. Scott Violet kicks off with a look at

Mustang: the little things:
I'm taking a brief hiatus from my series of blogs on application architecture to join in the mustang blog carnival extravaganza. The bulk of the major features have already been covered, in this blog I'll explore some of the smaller bug fixs and RFEs we've done to make mustang that much more compelling.

In From Monitoring to Diagnosing Memory Problem in Mustang, Mandy Chung writes:
"Mustang Beta Release is available!! Mustang has several enhancements in the VM and the JDK tools to help identify the symptoms and diagnose memory problems from using jconsole to monitor the memory usage and garbage collection activities to using jconsole to take a snapshot of the heap or turn on more diagnostic or tracing such as verbose GC."

the latest episode of O'Reilly Network's Distributing the Future podcast has a feature on Java Podcasters. Adapted from the ONJava article "The Java Podcasters" (parts 1 and 2), the podcast story contains excerpts from the Java Posse, ZDot, DrunkAndRetired.com, Swampcast, and the NetBeans Podcast, and is thus a quick way to sample these varied Java podcasts.

The coming year is bringing dramatic changes to the Web services landscape.

In today's Forums, erajsri asks
My first JXTA app : How do I reach out to the whole Internet, not just the LAN:
"I'm new to JXTA and building my first ever P2P app ! Thus Im quite eager to get it up and running. However I have certain concerns over it's functionality. Could JXTA be used to reach peers on the whole Internet? I mean in usual file sharing P2P apps like BearShare, Limewire, Kazaa etc you could get your peer to connect to the whole wide Internet, not just the LAN pc's. How do they make such a discovery possible?"

A guest has some solutions
Re: Matching real and virtual camera:
"To get accurate pixel metrics, which are highly desirable for virtual and augmented reality applications, measure the dimensions of your actual image area on the physical display surface with a ruler and set the dimensions using the appropriate methods of Screen3D. For less accuracy just use the dimensions advertised by the display manufacturer."
