Tejones Conf 18 / the next step of the tribe

The Joke

As I have described in previous posts, TheMotion's original team evolved into a kind of tribe with a shared culture (honeybadgers from team to tribe). A fundamental characteristic of this culture is sharing and learning as a team. So the next logical step in this evolution was to generate a space for just that... learning and sharing... our invitational conference, or rather, unconference.  Our Open Space, the HoneyBadgersConf / TejonesConf18.

It started almost as a joke, but we quickly convinced ourselves that it was an excellent opportunity to enjoy together and learn at the same time.

It took us a long time to agree on a date, but a month ago we were finally able to book a country house to spend the whole weekend and organize the openspace.

The Open Space / Sessions

We made a single track openspace. But although we were few we had many proposals so in the end some talks/sessions were left out of the panel.

• Craftsmanship. We saw together the talk Run 2018 - Masterclass: Craftsmanship (talk in Spanish from Xavi Gost) and discuss the ideas present in the talk. A very interesting discussion. I proposed this discussion to confront some ideas about agile, the dark side of agile and how to transmit the idea of agile software delivery.
• Show me your data pipeline. In this session, we talked about data processing workflows. We didn't focus on technology. The focus was on organizational and team design to develop and operate these data pipelines. You know, Conway's law. :) The session was proposed and conducted by Jorge Jardines.
• Traceability and observability. Fran Ortiz introduced us to the concepts of distributed tracing and observability for applications. We talked about opentracing, zipkin, and honeycomb and were able to make a small demo using opentracing.
• My life as a junior developer. Georgina gives a talk about her exciting evolution in our profession. It was a very inspiring talk and full of insights.  We talked about power relations, diversity, team culture, power dynamics, etc.
• A light introduction to Terraform. In this session, Ivan explained how to use Terraform. He detailed how it compares to other tools and approaches for systems/resources provision. There was a lot of diversity in the degree of knowledge about systems architecture, cloud, etc. This diversity generated a fascinating conversation that we continued in the next session.
• Kubernetes. In this last session Abel, Ivan and I explained the basic concepts of kubernetes and how they fit with the idea of applications that follow 12 factors.

The idea was to have more sessions, but the truth is that the lunches and dinners were longer than expected :)

Conclusions

The result of the experiment was remarkable, and although due to date conflict some of the Badgers could not come, we want to repeat the next year and even invite some friends.

On the one hand, I feel part of the tribe and its culture, and on the other hand an astonished spectator of this process of growth. For me, this process has been as surprising as it has been rewarding.

Good talks/podcasts (Nov 2018 I)

Some good talks that I show lately:

• Designing a high-performing team Alison Coward. How to grow high-performance teams (create new habits, communication, psychological safety, effective meetings, etc...)
• It’s Not Continuous Delivery If You Can’t Deploy Right Now Ken Mugrage. Great description of Continuous Integration and Continuous Delivery and all the needed practices (trunk base development, dark launches, feature toggles, etc). A very good description.
• How Your Systems Keep Running Day After Day John Allspaw. Good reflections and a new (for me) mental model to use failure as a "good" input for product and system design/architecture.
• Failure and Change: Principles of Reliable Systems #YOW!Perth Mark Hibberd Interesting talk to understand failure and how to architect to be resilience.
• DOES18
• Breaking Bad Leadership: The Anti Heroes of DevOps John Rzeszotarski. An interesting Journey using DevOps explaining the kind of leadership needed on each step and context.
• Digital Transformation: Thriving Through the Transition Jeffrey Snover. The first part of the talk is not very interesting for me, but the second part is very interesting to improve our mental models and surf in this fast pace changing environment. It gives some ideas for understanding current trends and learning to adapt.
• Operations: The Last Mile Damon Edwards. This talk is not only very funny, it is also a great description of the problems generated by a "classic" operations mindset and how to change to a modern approach / devops.

My Software Crafters Barcelona 2018

A month ago I had the pleasure of attending the Software Crafters Barcelona 2018. I think it's the fourth time I've been to this conference and it's among my favorites.

I loved this year's edition. The first two years the conference had around 80 attendees and an excellent environment for networking and learning in community.
Last year the conference, and we were around  200 participants, which was a major logistical challenge. Although I liked last year's decision, the truth is that we lost some of the networking and community feeling. However, this year the organizers have overcome all the challenges and achieved the same atmosphere that we had in the first editions.

The venue was in the center of the city, very well communicated and comfortable. The rooms used for the talks and workshops were, I think, very suitable. The only thing I think could be improved is that the English track was a little difficult to access. Still, I think the venue was a great choice.

Another thing I loved this year, is that the open space part was done on Saturday afternoon, instead of Sunday, as was done before. This decision has allowed more people to participate in these open space sessions.

The sessions I attended:

A cowgirl journey Slides Meritxell Calvo Video
Entertaining and inspiring talk about the path she has taken within the industry and the milestones that have marked her. Very interesting to see the importance of having women referents in technology, community and mentoring.

Communication Antipatterns and where to find them Slides Emma Baddeley
As an introductory talk it went very well. He did some emphasis on distributed teams but it wasn't the main focus.

The Science of Not Estimating Slides Anemari Fiser, Javier Sánchez Rois.
An excellent summary of the problems with estimations and how to use some other alternatives as probabilistic forecasting based on real data from the team. It was fascinating how they used Montecarlo simulations based in the past cycle time and lead time of the user stories delivered by the team.

Reactive microsystems Slides Ignasi Marimon-Clos 

The talk described how to evolve from Rest Microservices to more reactive microservices using CQRS. For each step of the evolution, Ignasi described the pros and cons and the actual options for the next step. The content of the talk was great, but the following conversation was even more significant.

Kubeflow (Workshop) Laura Morillo
We follow the lab "Introduction to Kubeflow on Google Kubernetes Engine"
It was an introduction to kubeflow and concepts needed to use it (kubernetes, ksonnet). It was perfect for me because it was not to depth but let me understand the architecture and the development flow.

Parallel Changes. Big changes in small steps.

I facilitated this workshop and from the feedback I got, it was quite good. :) Slides and additional information in the following blogpost.

Timeless Streams Slides Javier Salinas Polo https://twitter.com/MuSTa1nE
Interesting session on how to solve the problem of time use in systems that use event streams. Finally, they came up with a solution by sending timestamps as events. They used these marks to demarcate periods so that they could test without the need to depend on time.

Open space Sessions:

Going to production, Help! Session moderated by Laura Lacarra

During the session, we shared different ideas about how to push to production and operating software systems. We could see how there were two groups, one more aware of the DevOps culture that considered production as part of value delivery and another group that still saw a clear separation between development and operations. We talked about incident reports and other learning tools (game days, chaos engineering). We also talked about the DORA report, and some reference books.

When there is diversity, do you know how to manage it? Session moderated by Raquel Lainde

Some ideas that I extracted from the session:

• We should provide training on diversity (because it is a great asset, but we usually are not prepared to manage it).
• Learn about biases and social psychology help us to understand the problems and our reactions.
• It is much easier for someone with privileges to correct or point out non-inclusive behavior to another person with privileges (less risk involved).
• It is essential to identify and try to be attentive to situations of discrimination.

They recommended this book that I already have on my reading list:

Other notes and stuff:

As every year I leave with a lot of new ideas, experiments to do, some devirtualizations, a lot of interesting conversations and a great sense of community. I am increasingly proud to have a profession that considers sharing and learning to be fundamental. 

Thank you very much to the organization for the impressive work you do. Each edition, I left Barcelona with the desire to return the following year. 

Good talks/podcasts (Oct 2018 II)

Some good talks that I show lately:

• Product related:
• Product Managers,Product Owners and the need for Real End User Validation Richard Mironov. Great talk to understand Product Management (outcomes vs output, discovery and validation, different kind of Product organizations. etc...)
• Escaping the Build Trap Melissa Perri at Mind the Product San Francisco 2017. A classic one to escape from the feature factory mindset.
• The problem with Product Ownership Mark Schwartz Great talk to understand the tension between Agile IT and the classic management that continue thinking that IT is a cost center. Very interesting to understand why Agile IT can not be archived using a classic command & control approach.
• LKUK13: Cycle Time Analytics - Fast #NoEstimate Forecasting & Decision Making Troy Magennis. Good talk about hot to use probabilistic forecasting to obtain better results than using estimates and without all of the problems derived.
• Observability for Emerging Infra: What Got You Here Won't Get You There Charity Majors. Great talk about the complexity of our systems, architectural complexity, the unknowns unknowns and the need for events, observability, and testing in production.
