#SoCraCan

I love this description by Carlos Ble of what makes a good community. Many important aspects are mentioned and hopefully inspire others to consider them for the communities they are part of! 👏🏻

Your event’s #CodeOfConduct extends beyond the event and it’s digital spaces

We had an interesting discussion at #SoCraCan about whether we should allow people to attend the event, if they had behaved in a way that violates the event’s Code of Conduct *outside* of the event. What if that person “behaves” during the event? Wouldn’t it be unfair towards them to exclude them? Maybe they have changed?

Less than a month until I am back Nordic Testing Days in #Tallin where I will be speaking about, no encouraging you to start building better testing tools.

I've run previews of this talk now at #Codefreeze and #SoCraCan and in both instances received very positive feedback which makes me excited to share it with a broader audience.

Tickets are still available, and the city and the conference is absolutely worth a visit: https://nordictestingdays.eu/

#testing #architecture

#SoCraCan was a blast, lots of homework to think about. Long live the #OpenSpace #unconference

I miss #SoCraCan 😢

#SoCraCan 2023 says Hi!

I think I got a few people excited about #serverless at #SoCraCan
Slides are here:
https://coderbyheart.com/talks#serverless-architecture-for-iot-on-aws

The results made Edina happy.
#SoCraCan

TIL: Iceland 🇮🇸 has not DST.
#SoCraCan

Now trying to figure out what the role of an Engineering Manager is.
#SoCraCan

Together with Gustavo Gutierrez we started a new #Kata at #SoCraCan: Develop a teaching lesson planner and learn about date and time zones.
The outline exists already, but I have to double check the test data.

Their problem was that they couldn't get DynamoDB to serve the queries they need so they had to switch to something else. They were also close to the 400 KB item size limit. After switching to PostgreSQL they reduced the cost by 90%.
#SoCraCan

Now in the session by Juan Vega (https://www.linkedin.com/in/juanvegarodriguez) who shares why they migrated one of their systems from Serverless to Microservices.
#SoCraCan

He summarized the principles after the session:
- One to one relationship between entity and object
- Use Metaphor to understand the problem domain
- Favor immutable objects
- Create complete objects
- Create valid objects
- Do not use null/nil
- Do not use getters/setters, only when needed
- Do atomic changes: e.g. syncwith(newObject)
- Reify the architecture of the system in the system itself (subsystems)
#SoCraCan

A more extensive course about what he talked about is available in Spanish, here: https://academia.10pines.com/disenio_a_la_gorra

#SoCraCan

Fourth one: represent the architecture of the system in the system itself, so it can reason about the system itself.
This allows to swap out parts of the system, and swap between a monolithic approach or a Microservice architecture.

A book recommendation is Rebecca Wirfs-Brock book: Designing Object-oriented Software
https://books.google.es/books/about/Designing_Object_oriented_Software.html?id=KpJQAAAAMAAJ&redir_esc=y

#SoCraCan

Third one: only allow valid objects (do not use setters to create an object step by step until you have what you need).
#SoCraCan

Second one is: use good metaphors to derive a model.
#SoCraCan

The first heuristic of Good Software Design is to model every concept in the business domain as a software model.

He recommends two books to draw inspiration from:

The Evolution of Physics (Einstein/Infeld)
The Design of Everyday Things (Dan Norman)

Hernan Wilkinson (https://www.10pines.com/) came all the way from Argentina and talks about the 7 principles to build great software at #SoCraCan

Day 2 of #SoCraCan is starting.

What makes a successful community? We've discussed this in a big group at #SoCraCan

Gustavo Gutierrez speaks about the time and date challenges they encountered in one project.
#SoCraCan

We didn't find a Timezone #kata, so we came up with our own very simple one: https://gist.github.com/coderbyheart/33ffc41a2023a643da75fdb543a0e6f2 ... it tool already a lot of time to understand the problem and so the 30 minute timeslot was over quickly.
#SoCraCan

What is a team? A good question we are going to discuss now at #SoCraCan

Now in the workshop with Christoph Welcz (https://www.welcz.de/) on how to build a CRUD API using #Rust.
#SoCraCan

Did a preview of my upcoming #NTD2023 talk about writing better test tools at #SoCraCan after lunch and nobody felt asleep! 😜
Got great feedback, which reminded me to add a main aspect that I previously only implicitly covered.
It's really cool that there are events like this where I can prototype talks.

#SoCraCan lunch break before I do my session

This session is about iterative ways to develop software.
#SoCraCan

We are sharing tools and methods we use in our development process in the third session:
#SoCraCan

Now in the session with Adrián Ferrera (https://adrianferrera.dev/) who shares how he applied #HexagonArchitecture to the front-end code if his website.
#SoCraCan

#SoCraCan 2023 schedule for day 1.

First session is about non-verbal communication. And we picked the pool as the session room.
#SoCraCan

The sessions keep coming... #SoCraCan

They came to the right place. #SoCraCan

Carlos Ble (https://www.carlosble.com/) is the facilitator for #SoCraCan and explains the rules of the #OpenSpace.

The first day of #SoCraCan is starting, and the attendees gather for the opening session.

#SoCraCan proof that it's fun!

Such a beautiful detail at #SoCraCan: these #OpenSpace posters are hand-made by the organizer's family.

#SoCraCan is starting!

What a city! #SoCraCan #Tenerife 🇪🇸
