Hello 👋🏼

I bet you will realise how many errors we are doing, after watching this 18 minutes video by Dave Farley.
After that, go to have a look at your user stories and think on how you work in your day to day.

Hello
the other day on Bluesky I saw a post by Simon Brown about a user complaining that C4 model is just for monoliths and he linked this page 👇

Good morning

The article I’m going to share today is from Pat Kua, ex Thoughtworker and ex CTO @ N26.
It’s a practical article and has good examples of how to create effective teams. It’s nothing too new in this channel since we shared similar articles, even though Pat is exploring Project Aristotle, a research published by Google more than 10 years ago.

hello friends

do you know what is the Software Supply Chain?
It’s the entire ecosystem of components, tools, processes, and dependencies involved in developing, building, and delivering software. It includes everything from third-party libraries and frameworks to development environments, CI/CD pipelines, and deployment infrastructures.

In this article from RedHat, it is highlighted a key aspect: Security.

morning

today an interesting article about AI, AGI and the doubt that on the future of progress of LLMs.
Please take it with a pinch of salt, since the author is popular on a couple of platforms but I wasn’t able to verify the credibility of their words. It would be like me talking about AI and making predictions, without being an expert on it.

Today’s article is about balancing speed and durability. It’s the typical problem: build something small, fast and tech debt increases vs over-engineer and value delivery suffers.
The author presents us 7 principles for balancing durability and agility.

Hello there
some insights from Edu Ferro about Vibe coding

Hello folks

quite nice article shared by Felix Lopez on Bluesky. It's about over engineering and the experience of the author when they joined an early stage startup.

hello there

To comment your code, or not to comment your code? That is the question. There is a debate in the software development industry as to whether you should, or shouldn't comment your code.

Morning ☕️

it’s Monday.. sending you some good vibes and coffee/tea/monster (yeah some friends drink monster/redbull in the morning).
I was not going to share anything today but Edu Ferro just published a great article. We often repeat QUALITY when we develop. We want to build a solution that has high quality both from customer and code perspective. But what’s really quality? Edu explains it in this article.

Morning
even if the scope of one service in a microservices architecture is small, the code architecture within that single service can be hard, especially if you are not very proficient with patterns.
Here is an article by a friend and colleague, Albert Llousas, about patterns to apply within a service or a module in a monolithic application.

“Tactical” architecture: guidelines

hello there
there are many links here to TDD videos en blogs, but this one is a special one since Emily Batche talks about her experience, how she learned the technique and what problems she faced along the way.

Good morning and Happy Friday!

today’s post is about how Slack DevEx team analyzed and improved their end2end testing pipeline.
Quite interesting also to notice that they use a monorepo and they run e2e tests before merging changes into main/master 🤔

Why untested AI-generated code is a crisis waiting to happen

I’d probably remove “untested” because imo all the ai generated code is potentially dangerous, if you don’t know how to code or don’t review it.
