ExtroVert Proof of Concept Background 
TI/Technology’s self-imposed challenges 
 How far can we take a 100% open source solution in a short period of time? 
 Can the organization adapt and evolve? 
• Use of a packaged solution or a rapid-application-development framework 
• Agile-like software development approach 
Proof of concept goals 
 Support preliminary ExtroVert technical design efforts 
 Suitable for use in usability studies 
• Polished look-and-feel 
• Real data 
 Select ExtroVert functionality 
• 27 features in the areas of search, content management and utility 
• Informed by snapshot of requirements as of 10/2/06 
 Identify suitable external resources for upcoming CSS/DIV-based HTML layout efforts 
Rules of engagement 
 Small, focused, empowered team 
• Manish Shah, Brian Durand, Evan Petrie, Kyle Crum 
 Team encouraged to “think as a user” when confronted with ambiguities 
• Select questions escalated to single contact: Tony Bagdy 
• Answers to be provided within 1 hour 
 Frequent (weekly) releases/product iterations

 Multiple image croppings for new content 
 My Tasks 
11/2/06 - Ruby on Rails Pilot
Obvious Questions
6 
What is Ruby on Rails and why did you use it? Is it used by a lot of 
organizations? I’ve never heard of it. 
 Open source web application framework 
 First released to public in July 2004 
 Increases developer productivity by 4X-8X (vs Java only or other frameworks) 
 Acceptance and adoption by developer community has been tremendous 
 Imitation is the sincerest form of flattery 
• More than 15 “Rails-like” frameworks for other languages 
 TI/Tech researched open source technologies for iLab in mid-2005 
• Frameworks: Ruby on Rails, Django (both young frameworks) 
• Languages: PHP, Python, Java/JSP 
• Selected PHP for iLab, but retained Ruby on Rails on “watch” list 
 Used by a variety of Web 2.0 companies – no “large” scale sites to date 
 Basecamphq.com, odeo.com, 43things.com 
 Enterprise use is still emerging – small CNET projects 
 Latimes.com – Inpage RSS Reader, Travel(?) 
 Provide insight into potential challenges for latimes.com’s Ruby on Rails Projects: 
Inpage RSS reader and Travel (?) 
11/2/06 - Ruby on Rails Pilot
7 
Can we use Ruby on Rails to launch ExtroVert early? 
 Not recommended 
 Only consider if willing to accept significant risk 
 Product may to scale to support anticipated ExtroVert national traffic (testing still in progress) 
 Productivity gains are real and significant, but long-term viability is questionable 
 There are many languages and frameworks, likely that only 1-2 will dominate over the long-term 
• Java – 25 frameworks 
• Ruby – 4 frameworks 
• PHP – 58 frameworks 
• Python – 9 frameworks 
 Criteria beyond “developer productivity” suggest frameworks other than Ruby on Rails may dominate 
 Ultimately, too little information and too early in the space to attempt to predict a winner 
 Use of Ruby on Rails for ExtroVert might prompt conversion to another solution in 
18+ months 
 General attempt to rationalize technology environment OR 
 Difficulty locating resources/talent 
11/2/06 - Ruby on Rails Pilot
8 
Why was this so much faster than the solutions originally 
proposed for ExtroVert? 
 Primary contributing factors 
 50% tool selection 
 50% development methodology 
 Tool selection 
 Use of an open source framework that improves productivity – Ruby on Rails 
 Able to accept some risk with viability of framework since result was Proof of concept/prototype 
 Risk was acceptable for a Proof of Concept with short “shelf life” 
 Should be possible to recreate this – with slightly less productivity? – with similar tool 
 Development methodology 
 Adopted an “agile-like” approach 
 Emphasis on action/people over process 
 Should be possible to realize additional value after engaging an Agile coach 
11/2/06 - Ruby on Rails Pilot
9 
Ruby on Rails & Other Open Source Elements – Too Good to Be True? 
Why Ruby on Rails 
 TI/Tech researched open source technologies for Innovation Lab in mid-2005 
• Frameworks: Ruby on Rails, Django 
• Languages: PHP, Python, Java/JSP 
 Ruby on Rails favored by TI/Tech architect 
• Significantly improves developer productivity 
• Very promising framework, but still emerging and unproven in high-traffic scenarios 
• Placed on a list of TI “watch” technologies 
• ExtroVert POC goals provided opportunity for additional investigation 
 Other Considerations 
 LA’s technology architect (consultant) arrived at similar conclusion w/o influence from TI 
 LA plans to use Ruby on Rails for conversations with TI 
11/2/06 - Ruby on Rails Pilot
10 
Next Steps 
 Complete scalability test - 11/28/06 
 Refine proof of concept for usability tests – TBD w/Product Development 
 Complete analysis of “best bet” web application framework for ExtroVert – 12/15 
 Conversations with framework creators 
 Feedback from Web 2.0 
 Add’l industry research 
 Integrate feedback from ongoing Open Networks conversations

Why Ruby on Rails  TI/Tech researched open source technologies for Innovation Lab in mid-2005 • Frameworks: Ruby on Rails, Django • Languages: PHP, Python, Java/JSP  Ruby on Rails favored by TI/Tech architect • Significantly improves developer productivity • Very promising framework, but still emerging and unproven in high-traffic scenarios • Placed on a list of TI “watch” technologies • ExtroVert POC goals provided opportunity for additional investigation  Other Considerations  LA’s technology architect (consultant) arrived at similar conclusion w/o influence from TI  LA plans to use Ruby on Rails for conversations with TI 11/2/06 - Ruby on Rails Pilot
