Look who’s here! #newcrafts Image
Coupling and cohesion for the first time were defined in this book. #newcrafts ImageImage
“Software design is an exercice of human relationship” was written
Every idea will change the behavior of the software, which leads us to many more ideas (fan-out here).

Reason why Backlogs are bad ideas => because they are growing exponentially. @KentBeck at #newcrafts ImageImage
How things are affecting each others. #newcrafts Image
“Software design is an exercice of human relationship” (here between sponsors and geeks-changers). @KentBeck at #newcrafts Image
Saying “we will now work on the Structure during 6 months and adding no new features in the mean time” is not helping the human relationship between the geeks and the sponsors. 😀 ImageImage
We need to maintain the relationship. Image
Programmers very often don’t have respect in their own work. A kind of ritual scaring (should be painful) 🤦‍♂️@KentBeck #newcrafts Image
Be careful: Moving the structure (refactoring) may be very addictive and seductive, but need diminution return.

(It’s comfortable cuz we don’t even have negative feedback from users like when we deliver a change of behavior). @KentBeck #newcrafts Image
The cost of Software is equivalent to the cost of change which is equivalent to… the cost of coupling.

We need to reduce the coupling (at a reasonable pace) @KentBeck #newcrafts Image
Empirical vs Speculative software design (bets) #newcrafts ImageImage
Any comment saying: « be sure » is bad coupling 😄 #newcrafts Image
Software is not just about the money.

There is also beauty in coding. @KentBeck
#newcrafts Image
We can both try to bring more value to this world, and have pleasure (as geeks) doing so. @KentBeck

(That was a hell of a keynote!). Thank you #newcrafts for this. Image

Refactoring Blockers

- Lack of patience
- Seeking perfection (can be demotivating)
- Guilt-shame-despair
- I don’t know (we don’t trust our own ability-opinion
- No spears, no spikes
- No compassion

« Thinking takes time. » @ClareSudbery at #newcrafts

Couldn’t agree more. Reason why I always refer to the « sustainable pace » of eXtreme Programming with my colleagues and also ask them:

Can't you find your best ideas like me by walking or taking a shower? 😄 Image

#CQRS is not a general purpose style of architecture.

A thread ⬇️
The first time I built a CQRS system… it was in 2006. The term hadn’t be coined yet by Greg (that happened in 2010), but the practice was ubiquitous in finance with tons of high throughput platforms to build or to maintain.
Actually, the first time I’ve used this architecture style was not due to my young skills of tech architect, but rather on a technical constraint.

Him: last time you were saying that you wanted us to avoid using feature branches. Why? 🔽

Me: I was saying that if you want to move toward Continuous Delivery on that specific software, you’d better aim trunk based development.
H: ok but what you don’t like with branches?

M: Despite what people here are saying, they are very often long-lived. They last more than a day, more than a couple of days. Sometimes a week… When no merge conflict is detected at the end it’s ok.
Bad things happen when there is a merge conflict at the end of the day.

H: Yes, but is it that much painful? Aren’t branches our bread n butter?
