For those who want a systems focused advent to wind up the year, it’s begun!

Daily posts will refresh here: www.ruthmalan.com/Advent.html

And will be posted to the page for the day (which will also hold notes and links to work people share here or on their own blog, etc.).

Phase 1: Learn

Domain A accesses Domain B's data in the legacy directly

Phase 1: Learn Domain A accesses Domain B's data in the legacy directly

Phase 2: Migrate
The concept is validated, so migrate required logic to Domain B, create an interface, and migrate Domain A's dependency on the legacy to the new interface.

Phase 2: Migrate The concept is validated, so migrate required logic to Domain B, create an interface, and migrate Domain A's dependency on the legacy to the new interface.

Legacy-leveraged learning phase is the name I use for a pattern we've been using at PayFit in a few places recently.

This pattern is controversial because it violates my most important modernization principle: respect domain boundaries.

Building Robust Maintainable Software Using genAI with Clare Sudbery - Trifork Academy Join Clare Sudbery for a 2-day masterclass on building robust, maintainable software using genAI using test-driven development.

Have you had enough of all the endless chit-chat about AI? Yeah. I hear you.

So I ain’t sayin’ nuffink other than, I’m running a two-day workshop in Amsterdam on November 17th and 18th, getting the most out of LLM-augmented coding tools and having FUN with it.
Let’s not talk about it. Let’s DO It.

I really love that @gienverschatse.com talk was such a great compliment for mine. Honored to be the first one quoting her ♥️

Can you design a system in 2 hours? We gave it a shot at @dddeu.bsky.social!
We tackled a problem at the design level, using the #ACEDmodel 🟩🟨🟧🟥

Great designs, collaboration & questions!
And so many smiles 😄

I run this workshop from 2 hours up to 2 days in length. jcq.me/tdesysb

I recently watched @felienne.bsky.social make a case for feminism in programming language design www.youtube.com/live/-Br66SU...
(TY @lindamciver.adsei.org)

This talk sparked thoughts, helped me learn something new, and also triggered some complicated feelings. Sharing in no specific order (1/7)

That’s definitely on how works in real life. You have your decisions and then…some context brings questions. Thank you ! 😊

Woooow, this is cool, i was thinking about this and wasn’t sure…good idea !

I remember one hands-on code workshop that I attended gave a very simple example of the business project and while coding we were able to identify the pain points because of that 💖

When you’ve joined a workshop in a conference, what you liked about it? Will you improve something?
I’m still refining my architecture workshop for @codemash.bsky.social and I would love to hear some tips 👩🏻‍💻

@tekiegirl.bsky.social is the best ♥️

Of course ! Thank you for laughing with me and teaching @golang.org to the #OrlandoDevs community! 💻

Then also @williamcook.dev brought the fun and sad parts of using @golang.org in a fun presentation. We know that go users are there because of the cute mascote! #OrlandoDevs rock it !

I’m in the #OrlandoDevs ignite party and this quote is so true that it hurts. As @mentrix.bsky.social says: communication is one of the most important skills for devs and engineers 💖 @robschn.com presenting !

Exactly, using just those metrics to take decisions is not the best idea

28.11.2024 00:46 👍 1 🔁 0 💬 1 📌 0

I’m not saying that they aren’t useful or perfect, but if you base all your products on the Dora metrics then you aren’t looking far enough

27.11.2024 16:16 👍 0 🔁 0 💬 1 📌 0

I’ve experienced that some managers just care aboutDora metrics and some products like payroll or payments gateways don’t need to be changed so often.The important thing there is the time to recover,but do infinite commits just to get a metric up is the same as test minimum things just for coverage

I agree partially with this, because also DORA metrics can be use for the “evil”, what about if the product does not need to change so often? The one that I really like is the time to take to go back to business…and even that one can be controversial if it is not “that important”. Always depends

While I’m refining my workshop for @codemash.bsky.social I started looking at the #cards42org @innoq.bsky.social for some inspiration and… this card is the best! The upside down disclaimer was sad but I had fun shaking the wand (you never know when magic happens)✨🪄

Self-organization & the power of collectives are deeply misunderstood. First encountering them in open spaces curated by @bruceeckel.bsky.social, I was mesmerized.

"Facilitating Software Architecture" from O'Reilly describes how to bring this to your software. facilitatingsoftwarearchitecture.com.
