“Release Early, Release Often” is a proven mantra, but what happens when you push this practice to it’s limits? .i.e. deploying latest code changes to the production servers every time a developer checks-in code?

At Industrial Logic, developers are deploying code dozens of times a day, rapidly responding to their customers and reducing their “code inventory”.

This talk will demonstrate our approach, deployment architecture, tools and culture needed for CD and how at Industrial Logic, we gradually got there.

Process/Mechanics

This will be a 60 mins interactive talk with a demo. Also has a small group activity as an icebreaker.

Key takeaway: When we started about 2 years ago, it felt like it was a huge step to achieve CD. Almost a all or nothing. Over the next 6 months we were able to break down the problem and achieve CD in baby steps. I think that approach we took to CD is a key take away from this session.

Context

Industrial Logic’s eLearning context? number of changes, developers, customers , etc…?

Industrial Logic’s eLearning has rich multi-media interactive content delivered over the web. Our eLearning modules (called Albums) has pictures & text, videos, quizes, programming exercises (labs) in 5 different programming languages, packing system to validate & produce the labs, plugins for different IDEs on different platforms to record programming sessions, analysis engine to score student’s lab work in different languages, commenting system, reporting system to generate different kind of student reports, etc.

We have 2 kinds of changes, eLearning platform changes (requires updating code or configuration) or content changes (either code or any other multi-media changes.) This is managed by 5 distributed contributors.

On an average we’ve seen about 12 check-ins per day.

Our customers are developers, managers and L&D teams from companies like Google, GE Energy, HP, EMC, Philips, and many other fortune 100 companies. Our customers have very high expectations from our side. We have to demonstrate what we preach.

• You should walk away with some good ideas of how your company can practice CD

Slides from Previous Talks

Most eLearning simply automate the formal class-room training environment. Only difference is students can be distributed now.

Although a lot of money is spent on creating engaging, interactive, multimedia courseware, one vital ingredient is missing: Other People.

Many companies adopt a blended approach to bring in the other people aspect. But even face?to?face events are often delivered in a fairly traditional way.

Meanwhile outside of the formal learning environment in online colleges (online courses, classroom, workshops, etc) individuals are learning in other ways – often without realizing it ? whether it be by reading, listening or watching or simply by talking to one another.

Only recently informal learning been recognized as important part of learning and that it needs to be supported within an organization.

This presentation explains how:

There is something very powerful about online education (eLearning). Assuming that one can create really good courses, it enables any individual to start competing with the large Universities. (Many Universities have seen the benefit of online education and they have certainly started offering their courses online.) Students can be located anywhere around the world and they can learn things at their own pace. With social media one can even achieve a very high collaboration between the students (peers) and teachers. This can scale very well and since the class capacity is infinite, we can completely remove the barrier to entry. Finally education can be made very affordable, since the cost of running an online course is extremely low compared to the bureaucratic Universities. Thus it helps in “Bringing quality education to everyone“.

One of the real problems we run into with this approach is, how do you “certify” the student? Coz these individual educators won’t have the credibility like a University nor will they be able to give an acceptable degree/certificate as a “proof of learning”. The question is can social media/web fill the void?

The Social Media/Web is still at a very nascent stage, evolving rapidly. Today people don’t really use it to validate someone’s credibility online. As of today “Certificates” have more value.

Globally, using social web to certify people has not taken off. LinkedIn is trying. I’m (or should I say, I was) trying something similar with the Agile Alliance LinkedIn Group. Lot of other people like http://www.wevouchfor.org and http://www.workingwithrails.com/ have tried.

To think about it, Open Source (being a committer/contributor on an open source project) helps you build social credibility. This model has certainly worked for a lot of developers.

Things like http://www.topcoder.com/ and http://www.codechef.com/ are taking off very well. But they are different, not so much social media.

Imagine “real” people on the web can vouch for your experience, knowledge and skill. You can demonstrate the same with applications/tools you’ve built. Your social status speaks for you and you can completely do away with the traditional certification model. I certainly see us moving in that direction. Decentralize and distribute the ability to certify people.

For many years now, our Agile eLearning albums have been offered at a flat, USD price, regardless of where you lived in the world.

That is about to change!

Our Agile eLearning albums are now available to individuals around the world at new, lower, regionally adjusted prices.

What Does This Mean To You?

It means that we have introduced a new Individual pricing model to complement our Corporate pricing model. The new model, based on Purchasing Power Parity (PPP), makes our Agile eLearning more affordable for individual purchasers.Individuals will still see USD album prices — however, they will be adjusted to reflect the purchasing power of your country’s currency.

As of April, 2010, if you live in India , you can purchase an Individual License to our Code Smells album in Java for USD $126.00, rather than the Corporate price of USD $210.00.

Even if you live in a country where the PPP discount is modest, Individual Licenses will still receive a 15% discount:

As of April, 2010, if you live in the United State , you can purchase an Individual License to our Code Smells album in Java for USD $179.00, rather than the Corporate price of USD $210.00.

Why Are We Doing This?

We’re devoted to helping people throughout the world acquire Agile skills at a reasonable price. We’ve helped large corporations, like Google, HP and Standard Life, realize this goal and now we’d like to make the same training affordable for individuals as well.To learn more about Agile eLearning, please visit our Greatest Hits Shop.

It appears to me that the Agile Community is falling behind the innovation curve. At conferences, user groups, mailing list, etc, we see the same old same old stuff (may be I’m missing something). So where is the real innovation happening? What space should I be watching?

These were the questions I posed to the group @ the SDTConf 2009. Later, during our discussion at the conference we tried answering them. After a wonderful discussion we come up with some suggestions:

• Web 2.0
  • Highly Scalability, Performance and Operations space
  • No SQL
  • Continuous Deployment and Monitoring space – Owen’s Slides are a good starting point
  • Watch out for conferences like O’Reilly’s Velocity
• Alternative Language (non-mainstream languages) space. Lot of interesting experiments going on in
  • Dynamic language space
  • Functional language space
  • Hybrid language space
• Domain Specific Language space
• Could Computing, Parallel Computing (Grid Computing), Virtualization space
• Code Harvesting Space – Check out Test Driven Code Search and Code Genie as a starting point
• Complex Adaptive Systems and its implication on our social interactions space. Dave Snowden’s work is a good starting point
• eLearning and visual assessments (feedback) of a programming session. Check out Visualizing Proficiency
• Polyglot Programming space
• With Google Apps, people are able to build 100s of Apps each month and get instant feedback on their ideas
• Social Networking and Second Life space
• Conference: Lot of interesting experiments are been conducted in the conference space. Conferences have evolved to something very different from before.
• Distributed Development and Remote Pairing space
