Tracking change and innovation in the enterprise software development community
 |
QCon is an enterprise software development conference for team leads, architects, and project managers covering Architecture & Design, Java, .NET, Emerging Languages, NoSQL, Browser as a Platform, Software Craftsmanship, SOA, Agile methodologies and other timely topics. Last years' QCon London drew over 500 people despite the economic downturn. There were thousands of tweets and hundreds of blogs written by attendees - see Key Takeaway Points and Lessons Learned from QCon London 2009 for a feel!
The QCon conferences are taking place yearly in London, San Francisco and Beijing!
The 4th annual QCon London (March 10-12) has been announced and registration is open!

The line between development and architecture is tricky. Some say it's fake, that architecture is an extension of the design process undertaken by developers; others say it's a chasm that can only be crossed by lofty developers who believe you must abstract your abstractions and not worry about implementation details. There's a balance in the middle, but how do you move from one to the other?
Last week, InfoQ published a piece on YouTube offering HTML5 beta for its videos, in H.264 format. Shortly thereafter, Vimeo announced an HTML5 beta as well, also using H.264 as the video codec. However, Mozilla has come out against using H.264, whilst the recent iPad launch has focussed on the H.264 hardware decoding. Has Flash finally met its match?
Google has added five security enhancements to Chrome in order to make browsing more secure: cross-documents message posting, Strict Transport Security, Origin and X-Frame-Options header fields, and Reflective XSS Filter. Some of these features have already been or are to be implemented by other browsers.
In this second article in the Resource-Oriented Architecture series, Brian Sletten discusses the benefits of REST, what constitutes a resource, associating metadata with a resource, the pitfalls of common models of resource metadata, SPARQL, RDF, expressing RDF facts, RDF triples, querying RDF, and sample RDF queries.
Google recently announced their new programming language, Go. It is designed to bring some of the advances of modern programming languages back down to the systems arena where C still dominates today. However, the language is still experimental and evolving. This primer will help explain the intricacies and structure of the Go language for those who are interested in learning more about it.
For Grady Booch the foundation of a good architecture is patterns, SOA being just one of many patterns. In this Second Life presentation, Booch attempts to bring more clarity to some basic concepts: enterprise, patterns, frameworks, architecture, SOA, development, architecture lifecycle, best practices, what they are and what the aren’t, emphasizing the role and importance of patterns.
Charles Lee explains why cloud computing is not just a hype but rather the trend of a decade, and introduces the audience to several SpringSource tools, especially Cloud Foundry, showing how they can be used to create and manage cloud deployments.
Heroku's Adam Wiggins talks about how Heroku, Add-Ons, Ruby, and how Heroku manages to work around Ruby's inefficiencies using Erlang and other languages.
In this interview, Dr. Mercuri defines computer forensics, then discusses how forensics apply to criminal, civil, and intellectual property law. She addressed the challenges that technological advances, (e.g. RAID, cell phones, GPS devices, and Cloud Computing) increase the challenges faced by the forensic computer scientist. She also discusses appropriate actions if you suspect security issues.
Composite Software offers a new level of granularity when compared to SaaS (Software as a Service). Composite Software is about enabling "right-sourcing", i.e. move (or keep) arbitrary small or large elements of functionality wherever it is the most cost effective to operate them, not just entire systems. Economically, "right-sourcing" is far more efficient than "outsourcing" and SaaS. The goal of this book is start by understanding today’s software construction processes and technologies and explore why and how it should be evolved to support core composition mechanisms.
Within this book you will find everything you need to get up and running using Struts2 – from the architecture and configuration, to implementing actions and the supporting infrastructure such as validation and internationalization. Above all else, it focuses on the practical – with plenty of code and productivity tips to get you started using Struts2 today.
Domain Driven Design is a vision and approach for designing a domain model that reflects a deep understanding of the business domain. This book is a short, quickly-readable summary and introduction to the fundamentals of DDD; it does not introduce any new concepts; it attempts to concisely summarize the essence of what DDD is, drawing mostly Eric Evans' book, as well other sources since published such as Jimmy Nilsson's Applying Domain Driven Design, and various DDD discussion forums.
