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.

Reviewing what's available in the Open Source world for CFML

I thought this might be a bit of fun to post. It's a short "What's Hot in CF?" preso from the "day zero" meeting prior to MXDU 2005.

Presentations from the CFinNC conference

CFUnited is the ideal conference for developers to discover the latest in ColdFusion, Flex and AIR technology, share ideas & experiences, discover potential clients, and begin collaborating on projects.
