It’s Friday!!
And I’m not a big fan of 30 pages RFCs with sequence diagrams, ER model diagrams, all the use cases.. it’s upfront design!
Just explain what the thing (service?) is going to do, C4 level 2 diagram and that’s it.. get feedback but don’t loose time.. go live asap

I’m fan of Lightweight RFCs https://www.thoughtworks.com/en-es/radar/techniques/lightweight-approach-to-rfcs

ps: have a great weekend

Hello folks

here is an interesting article by Javier Lopez.

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.
