I recently returned from a trip to Israel. It was my first time in Israel, and the trip was a success. I was there teaching TDD to a client in Haifa. I also managed to take some time to visit some of the sights of Haifa and see a little of Tel Aviv. I even managed to get out of the country right as the recent aggressions began.

The purpose of my trip was to provide training for my client in Pragmatic Test Driven Development. While there, I managed to meet with some good friends like Atzmon Hen-Tov, David H. Lorenz and Lior Schachter to discuss an open-source implemenatation of an AOM framework called Ink, which is itself an evolution of ModelTalk.

It was good to see my colleages again and to visit Israel, and even better to get out just in time. Still, I look forward to being able to go back again. I hope to see more of the country next time and to participate in future collaborations with my colleagues.

 

I just got back from Kraków, Poland last week where I attended JDD 2012. While at the Java developers conference, I presented a talk called "When Should You Consider Meta-Architectures? Using Meta to Scale the Cloud." I also spoke on the subject, "Pragmatic, Not Dogmatic TDD: Rethinking How We Test" with Rebecca Wirfs-Brock.

I've just barely recovered from JDD and now I'm heading to Haifa, Israel. This is my first time in Israel so I'm excited about being there. While there, I'll be presenting a course on the subject of Test-Driven Development for a client of mine who maintains offices there. I've never been to Israel, so I'm excited take in some of the sites in Haifa and possibly Tel Aviv. If you'll be in the area and would like to get together, get ahold of me.

 
I am currently in Panama City Panama for the first International Symposium on Software Architecture and Patterns.  It is being held in conjunction with the tenth Latin American and Caribbean Conference for Engineering and Technology. I was on the Planning Committee for the convention this year and I have been asked to give a keynote address.  
 
The following is a description of my keynote address which is entitled "When Should You Consider Meta-Architectures? Using Meta to Scale the Cloud." 
 
The recent surge in cloud computing has really changed the way architectures are evolving. Platforms as a Service (PAAS) and Software as a Service (SAAS) is becoming where organizations can get necessary resources as needed without having to worry about many hardware and software configuration issues. It is no longer the case that systems need to be isolated to a single platform or set of platforms with a lot’s of possible maintenance issues. The core premise with the cloud is that different resources including services can be allocated and integrated as needed, adapting to the specific needs of the organization or systems being built.
 
Additionally, “Cloud Computing” allows for a large numbers of users and flexibility for different services being provided. Different types of resources and services provide maximum configuration and flexibility within the cloud and metadata is key for this type of variability. , It is quite often the case that cloud applications need to be able to dynamically adapt at runtime, without stopping the application. It is important to provide a way for users to customize their own experience with cloud applications. Trying to do this without ways for users to describe and adapt to their specific needs will not scale at all. This scaling and adaptability problem becomes even more imperative when you have many different organizations with different requirements. If, in the cloud, these organizations cannot adapt and define their different needs, the cloud solution would not be that compelling to them. In these situations, it is important to allow the ability for different customizations of the services, and to allow the users themselves to dynamically configure the systems. In order to be able to adapt to these dynamic requirements, the demand for Meta-architectures, such as those provided by Cloud solutions such as SalesForce, are necessary to make these types of adaptability possible!
 
What does it take to build a system that can be changed and adapted without programming? When is it appropriate to consider stepping into the meta world to build such an extensible system specifically in the “Cloud” environment? This talk answers these questions and presents ideas about using meta-architecture to scale in the “Cloud”. 
 
I am also leading a BootCamp that focuses on teaching the principals of writing and being a part of the patterns community.
 
This is my first time to Panama and have enjoyed seeing the sites and taking many photos of the Panama Canal, Old City Ruins and the old city, which was rebuilt after the city was burned down by pirates in the early 1600's!
Panama is very modern now with huge growth and growing economy.
 

Just last Saturday, I returned from Dallas, Texas. Today, I leave for Penang, Malaysia! I was in Dallas attending Agile2012. While at the conference, I hosted a workshop with Rebecca Wirfs-Brock on the subject of Testing System Qualities. During the workshop, we showed how to write Quality Scenarios that emphasize architecture capabilities such as usability, security, performance, scalability, internationalization, availability, accessibility and the like.

We also collaborated on a lecture entitled Pragmatic, Not Dogmatic TDD: Rethinking How We Test. During the presentation, we challenged the "norm" for TDD. While we agree that testing should be an integral part of your daily programming practice, we believe that you don’t always need to derive your code via many test-code-revise-retest cycles to be test-driven.

I had great time at the conference and especially enjoyed meeting up with friends like Linda Rising and Jutta Eckstein.  

Next on the agenda is a trip to Penang, Malaysia.  I am excited to be making my first trip to Malaysia.  The purpose of my trip is to teach a course on Pragmatic Test Driven Development.  While there, I will be visiting with a friend and taking the time to do a bit of site seeing.  

 

 

I attended another Agile Portugal this year in beautiful Porto, Portugal. Pre-Conference started Thursday early evening with a talk and discussion about "Better Science Through Art", June 21st. That was followed by watching Portugal win the Euro 2012 quarterfinals.

On Friday, the conference started with many Open Spaces which lead to some great dialog about various topics. Saturday started with a talk from Richard P. Gabriel's entitled "Life in the Trampoline of Amnesia." After that I took part in several talks and speed-talks. In the afternoon, I gave my Keynote address entitled, "Pragmatic, Not Dogmatic TDD: Rethinking How We Test."

Saturday night was the night of the annual Festival of São João party in Porto...it has become a tradition for me. The music, lights, fireworks, and food are amazing every year. The real highlight of the event for me was getting to see my friends again, particularly Ademar Aguiar, Richard Gabriel, David West, and Peter Sommerlad. Richard, David, and I did some post-conference site-seeing. The convention really went by too fast, and I'm already looking forward to next year!
