As businesses become more sophisticated in their use of the Internet, a single web site in a single language is becoming less common and the trend is toward multiple languages and often to multiple, regional and/or branded web sites. Supporting multiple sites (multiple domains) on a single code base is known as "multi-tenant" architecture. Multi-tenant and multi-lingual web platforms present a number of interesting challenges.

I've helped build two such systems, a content management system at Broadchoice and more recently a dating platform at World Singles. In this deep dive, we'll look at the pros and cons of many of the decisions my teams had to make as we faced and overcame a variety of technical challenges. We'll cover different approaches to web, application and database infrastructure, authentication and security, skinning, content management in multiple languages, and more!

Software development has cycles. In the 1980's, functional programming languages were "hot" but somehow they never became mainstream. Instead, object-oriented languages took over the mainstream and that has shaped how most of us program today. However, functional programming languages have started to get more attention recently, partly because Moore's Law has begun to stall and instead of chips continuing to get more powerful, we are moving to multiple cores - and we need to take advantage of concurrent processing in order to leverage those cores.

Functional programming languages focus on immutability of shared data and higher order functions. The former makes concurrent programming much easier and the latter allows for small "pure" functions to be easily composed into sophisticated algorithms. In addition, the nature of functional programming allows for much easier testability - in the absence of side effects.

In this session, you'll learn about some functional programming languages that are making waves these days as well as some techniques you can apply to solving your own problems in a way that's easier to test, easier to reuse and easier to leverage concurrency.

Solr, an open source, enterprsie search platform from Apache, is becoming the standard search engine for use with ColdFusion. In this session, we will discuss how to set up Solr collections, index collections and run searches against those colelctions and some of the differences between Solr and Verity.

Take your application scalability to the next level. This session will take you beyond the basics of caching in ColdFusion 9.0.1, diving deep under the covers of how ColdFusion leverages Ehcache to boost application performance. We'll cover tips and tricks to leverage the newest features of Ehcache in ColdFusion 9.0.1 as well as how to take advantage of advanced functionality not directly exposed to ColdFusion such as replicated caching, distributed caching, and the newest feature being added to Ehcache: Cache search.

A short overview of how I used CFML / ColdFusion to build a little, one-man start-up called Refynr.com. Not much detail, but gives a taste of how I did it in less than 5 months.

Do you know what MURA CMS, an open source ColdFusion based Content Management System, can do for you as a developer? Get yourself introduced to MURA, its architecture, its event model, its API, its extension possibilities and be ready to get started!

Learn simple and effective ways to scale and boost the performance of ColdFusion applications using Ehcache. This session will cover why caching is important, how ColdFusion leverages Ehcache to boost performance, tips and tricks to leverage the newest features of Ehcache in ColdFusion 9.0.1, and how to take advantage of the ability to snap in Enterprise Ehcache to scale out your applications.   

This is my presentation: Getting to Know AntiPatterns-Emergency Backup Edition.

It contains screenshots of my very lame sample app.

Join Rob Brooks-Bilson for a discussion on configuring, securing, and maintaining Adobe ColdFusion servers for optimal performance and stability. Beyond configuration, he'll also discuss the server monitor and the new Adobe AIR based server manager.

With new application deployment paradigms, we have more options to get our applications in front of our users, but also create new security vulnerabilities. This session will investigate how to avoid some common security pitfall, and the techniques used to identify and track them.
