My first manager at Uber started a GitHub page back at the time with resources to become a more proficient developer - ones he personally found helpful (he did not have a CS degree). I realized he is *still* updating it, 7 years later! A neat list: github.com/charlax/profes…

@scotthannen @vkhorikov If you refer to your questions of entity vs. value, there are typically two ways to compose any kind of data, and this has nothing to do with DDD. This can also be described as reference by object or reference by value, but I think composition best suits this discussion. In the…
Imagine a tech conference having no CFP, as they reach out to speakers directly. They successfully attract some of the most heavy hitter men speakers in tech, and 3 women speakers. Now imagine my surprise that 2 of those women are FAKE profiles. They do not exist. Nada.
Hot take: behavioral interview questions (“Tell me about a time…”) should be sent to candidates in advance. Reasons to send in advance: 1. More time to comb through their whole career to find a good example is a *good thing*. Otherwise you can’t tell the difference between…

Assuming a #DDDesign Bounded Context requires model persistence, it should have it's own, non-shared database (at least one). That is, no other Bounded Contexts may have operational access to that database. Yet, "database" can be an overly generalized constraint: 1. The point is…
Why wait for cloud deployment to tell you that things aren’t working if the type system could have done so? My latest blog post connects the dots across DDD, cloud automation, and type systems: architectelevator.com/cloud/ddd-tech…

I'm extremely honored to write a book for @VaughnVernon signature series: "Balancing Coupling in Software Design" The book combines the history of software engineering, physics, statistics, biology, and industrial engineering to derive simple rules for designing modular software.
@ylorph I think large parts of the industry have learned that they can't trust the engineering dept. So they 'agile' and micro manage engineering. So engineers lose agency and feel like they're not trusted... So they try to put on a face of being flawless... and it harms us.
I wanted to upgrade a project to PHP 8.2 and figured I could use @rectorphp for this. Not only was I right, but I had also completely underestimated how easy it was going to be 👇 tech.osteel.me/posts/upgrade-…
2 years ago I gave away 5 course those who can't afford it, to learn more about PHP. This week I met 2 in person in Porto ❤️️ It's a sign to repeat😇 * I give 10 people 250 € for course/training Retweet to enter, comment with your course choice. * Till 21st January noon
If you believe you are following the Liskov Substitution Principle in a class hierarchy, but your naming conventions lead to classes named Abstract* or *Base, then you are not, in fact, following LSP. LSP described a subtyping relationship, which also applies to naming.
Have you heard about free range management? @SteveTauber and @andreascreten wrote a guide to managing knowledge workers, structuring teams, and shaping the work so that an organization can find success. This resulted in our very first book: bit.ly/3Y0tFeT
As software becomes harder to change over time (this will happen if you do not make it easier) the maintainers will convert from advocates of change to advocates of stability for all it depends on. This is why the BC crowd is so strong, most engineers end there.
Pretty much every feature of every information system I wrote in my entire career can be reduced to this sequence: Data source > information we have > business rules > information we want Each of these is a class or a small collection of classes.
Here are the slides from my #DDDEU keynote: speakerdeck.com/vladikk/fracta…
This article will help you improve your development docker setup. You will no longer have to manage exposed ports on your database containers or other non-http services. bit.ly/3M1VY5g
