software design patterns and lessons learned from nature - jaromil

Software Design patterns between Agile and Permaculture

Denis “Jaromil” RoioDyne.org CTO and co~founder

Agile and Software Architecture Symposium28 September 2016, Arnhem

Roots: hacker community from the BBS times (est. 1999)

Now: think &do tank (not for profit software house)

Free and open source, towards recycling of existing tech

Simplicity, minimalism, UNIX principles... GNU furrr

Resilience, long term, community based approach

Leading EU research onblockchain, currencyand p2p economies

Permaculture: an approach to the design of human settlements and agricultural systems.

Focuses on:

obtain a yield for human needs aim to create stable and productive systems mimic the relationships found in natural ecology harmoniously integrate the land with its inhabitants

Historical colocation:

Traditional (preindustrial) agriculture was labor intensive Industrial agriculture is fossil fuel intensive Permaculture is design and information intensive


Observation: observation of the subject during all possible occurring circumstances and transformations of its context.

Boundaries: individuation of the boundaries touched by the subject, the surface of interaction with other subjects.

Resources: inventory of resources the subject can dispose of, what comes and goes from and to outside.

Evaluation: analysis of how elements interact and define the subject, establishing the nature of the project.

Design: definition and mapping of the subject, imagining it in all its possibly different aspects.

Implementation: plan how to realise the subject, creating a plan of action for its full realisation.

Maintain: consideration of the maintenance aspects involved by the design and its sustainability.


Work to assuage fears, to celebrate positive results. Be patient if things get sticky. When all else fails, return to ways to create even more community. Do anything else you can to bring people closer. Celebrate every small success with food.

Peter Schuh, 2004 “Integrating agile development in the real world”

We make our software very portable and we make our software standardized so that other people can easily have portability, so we are aiding portability from every possible direction. Meanwhile, you see Microsoft deliberately introducing incompatibilities and deliberately blocking interoperability.

Richard M. Stallman, 2004
