Greg Cupal applies constructor theory (from physics) to agile software work #agileAndBeyond
Prevailing Consensus in science: from one state to one state, according to laws
Constructor theory: what can and can’t be caused to happen?

Get a solution space, eliminate the impossible, and what’s left could happen. This is more complex
Instead of from Here to There with a Plan “oh no, this person is gone, whatever shall we do”
From available inputs through tasks we could perform
to various points in the solution space.

We don’t know the end point, but we know where we can’t get.

How to sell your ideas, by Tom Bellinson
hint: expertise and explanations won’t do it.
#AgileAndBeyond ImageImage
Step 1: focus on their win. Find out what it is by asking questions.
if you can’t deliver on THEIR goals, move on. #AgileAndBeyond ImageImageImage
your goal is to enter the other person’s world, so you can communicate with them.
figure out their communication style and use that. @tomsbigideas Image

How do you take a legacy system toward fast flow of change? @suksr takes us through an evolution
using wholistic approaches including DDD, Wardley Mapping, and Team Topologies #QConLondon
The Wardley Map is only part of Wardley Mapping. There’s a whole strategy cycle

from @suksr #QConLondon
Team Topologies has categories of teams, and even more important: consciously plan the interactions between teams

Slow means risky. 130000 dev hours in a single weekend deploy

@audunstrand and @trulsjor #QConLondon
It’s not about how fast the team can program.
It’s about how fast the team can find solutions to each problem, uncover organizational secrets for how the domain works and should work.
There’s a conflict between cross-functional teams and the organizational hierarchy.

And alignment is a Challenge in autonomous teams

Flow in a software team is a socio-technical property.
Dropping flow comes with downtime, bugs, and other general misery.

from @ntcoding #QConLondon
Enforcing the same JIRA workflow doesn’t make developers interchangable.
“It takes me weeks to develop rapport with teammates, months to learn domain and code, a few hours to learn a JIRA workflow.” @ntcoding #QConLondon
Smooth devex, sustainable flow:
“This is working in the government, six years ago.
No one else has an excuse anymore.”

This morning at #QConLondon , @glenathan tells a story of an experiment at Circle CI: for this greenfield project, let’s have NO LOGGING.
Instead of logs, events! that make traces!

“Events are good logs.”
They’re data-first instead of human-first; they wrap units of work with durations; they can be explored multiple ways

@glenathan #QConLondon
They found best practices like: wrap each unit of work; report errors in a standard field; use span names that are specific enough to tell you what’s happening but general enough for useful grouping.

and now what we’ve all been waiting for: @KevlinHenney keynote #QConLondon

“If there’s any probability, even so close to zero it won’t fit in a floating point number, it is not impossible”
Representations are never perfect.
“Software development is the creation and maintaining of illusions.”
@KevlinHenney #QConLondon
Programming paradigms are ways to organize our illusions.
