How EverTrue is building a donor CRM on top of ElasticSearch. We cover some of the issues around scaling ElasticSearch and which aspects of ElasticSearch we are using to deliver value to our customers.
How does a full-text search engine works? How is the index built and searched? Can I use PostgreSQL as a full-text search engine or should I go for a more specialised solution? How does one configure and use PostgreSQL search?
This presentation covers all those aspects, based on the work we did to index teowaki.com. It was presented at PgConf EU 2014 in Madrid

ElasticES-Hadoop: Bridging the world of Hadoop and ElasticsearchMapR Technologies
In this talk, we will provide an overview of Elasticsearch for Apache Hadoop (ES-Hadoop), which includes integrations between the various Hadoop libraries, whether batch (Map/Reduce, Pig, Hive) or stream oriented (such as Apache Spark). We will also cover the YARN support and the HDFS snapshot/restore plugin available as part of ES-Hadoop. We will talk about the upcoming ES-Hadoop 2.1 GA release and near-term roadmap.
An introduction to and a couple of examples and tips on how to use Elasticsearch for general data analytics. Examples are based on Elasticsearch version 2.x.
Groovy speech I held last year for introducing a new JVM language as substitute of Java. Easy and intuitive, it offers new features unknow to its parent yet.
A presentation given at the Lucene/Solr Revolution 2014 conference to show Solr and Elasticsearch features side by side. The presentation time was only 30 minutes, so only the core usability features were compared. The full video is embedded on the last slide.
Query DSL in Elasticsearch is a way to perform query on elasticsearch cluster.It is rich flexible query language
We can define queries of elasticsearch in JSON format.In this presentation we will see type of query dsl and its usage.

ASTs are an incredibly powerful tool for understanding and manipulating JavaScript. We'll explore this topic by looking at examples from ESLint, a pluggable static analysis tool, and Browserify, a client-side module bundler. Through these examples we'll see how ASTs can be great for analyzing and even for modifying your JavaScript. This talk should be interesting to anyone that regularly builds apps in JavaScript either on the client-side or on the server-side.
Lets look at writing a new Struts 2 application from square one, using the Yahoo User Interface (YUI) Library on the front end, and Struts 2 on the backend. YUI provides the glitz and the glamour, and Struts 2 provides the dreary business logic, input validation, and text formatting.
Ajax is the web's hottest user interface. Struts is Java's most popular web framework. What happens when we put Ajax on Struts?
In this session, we look at writing a new Struts 2 application from square one, using the Yahoo User Interface (YUI) Library on the front end, and Struts 2 on the backend. YUI provides the glitz and the glamour, and Struts 2 provides the dreary business logic, input validation, and text formatting.
During the session, we will cover
* How to integrate an Ajax UI with Struts 2
* Basics of the Yahoo User Interface (YUI) Library
* Business services Struts can provide to an Ajax UI
Who should attend: Ajax developers who would like to utilize Struts as a back-end, and Struts developers who would like to utilize Ajax as a front-end.
To get the most from this session, some familiarity with an Ajax library, like YUI or Dojo, is helpful.
This talk is focused on tuning analysing and optimizing MongoDB query and index with the use of Database Profiler and "explain()" function.
Also, performance of database can also be impacted by configuring the underline ( Linux ) OS with some recommended settings which do not come by default.
What the web platform (and your app!) can learn from Node.jswbinnssmith
The web platform has a ton of warts. They're the result of historical baggage much of which could have been avoided.
As a frontend developer at Atlassian Bitbucket I've worked on apps big and small and have seen the benefits of composition and reuse of many small modules in the web browser. We compose together and compile over 1,000 modules in Bitbucket's frontend and ship them to user's browsers many times a week.
Learn how small modules solve these problems and more, how the future of the web is bright, and how to bring modularization and composition to your web app.
Bob Tiernay explores the fascinating world of jq, "the JSON Processor”. Starting with a motivation, he then covers the language, provides helpful tips, showcases a real world example, cautions some things to avoid and finishes with a discussion of the ecosystem.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
