I used to think software could be written in a definitive, “perfect” way. Just use the right patterns. But I realised it’s all about modelling things in a human way. And hide the complexity. This means trade-offs everywhere and you have to make the best of what you’ve got. Unsatisfying but true.

I failed a job interview technical test relating to Domain Driven Design because I used too much abstraction while covering money currency types. To be fair, I over complicated it. Lesson learned: keep all that stuff simple, one big-decimal value object, and in one domain service.

@vaughnvernon.bsky.social Hi there Vaughn! I’m loving reading “Implementing Domain-Driven Design”. It’s great stuff. I spotted this little doozy.

I’m currently reading Vaughn Vernon’s “Implementing Domain Driven Design”. Brilliant stuff. A big book but full of quality ideas.

Auto-incremented IDs vs generated UUIDs. What do you think?

Better Controllers: - Controller <- Inject UseCase + Presenter - Controller handles/scrapes/validates request - Creates a Command DTO - Invokes UseCase with DTO - Presenter <- Inject Repositories + View renderer - Controller invokes Presenter - Controller sends output to client

When you have a bad programming idea, ChatGPT is great! It will guide you step by step on how to turn your bad idea into an incredibly complex bad idea that does the same thing but perfectly conforms to the SOLID principles. 😄

Laws and constitutions are just words on paper. Their virtues rely on the willingness of enforcers (police, armed forces and judges) to uphold the words, along with the good nature present in all people. Weakened personal values or corrupted enforcers unlock the door, allowing tyranny to walk in.

Has anyone used the Presenter and ViewModel pattern from a UseCase? If the output can vary (e.g.- web page with user details, special offers, adverts etc. VS command line which just wants “Success!” or “Error”) then how does the UseCase know what to give the Presenter?

Trump is an enemy of us all. Europe needs to unite - and the UK needs to rejoin the EU. If you want to see that happen… join European Movement UK right now. We’re driving this. ✊

Keir Starmer! Nice one. A leader with a backbone in European politics for once. Someone standing up to a bully. PM 'ready' to put troops on ground in Ukraine to protect peace

I used to frequently discover fun websites that I enjoyed and would bookmark. I felt happy, enriched and inspired. That doesn’t really happen any more. What we need to invent is some sort of “world-wide web” where sites link to other related sites. Surprised it hasn’t already been done 🤷‍♂️🌍😉

People in the 20th century would do things when they got pissed off. People in the 21st century just post messages to everyone else, who, in turn post very similar messages to everyone else. Nobody actually does a thing because they believe posting and reading is somehow changing things.

And so, when the time came the humans willingly plugged themselves into The Matrix. The machines and their early masters barely had to do anything at all…

I’ve killed off my Twitter/X account now. Good riddance! I couldn’t take the constant hateful propaganda.

I’m beginning to wonder if anyone in the web development world knows about Event Sourcing and Domain Driven Design or Hexagonal Architecture… Are we all stuck with CRUD? Maybe this is just a backward PHP thing where the framework counts for everything. #php #ddd #dddesign #eventsourcing

Just deactivated my Twitter account. It feels kind of liberating. I didn’t really need anything on there anyway. I slightly felt like I was attached because of old interactions. But hey, all gone now. So long mother-Musker!

If you want to play the Beatles, good luck to you. Their chord structures are so difficult considering how simple the songs sound!

How do I delete my Mastodon account? The platform never really worked for me.

In the movies we used to watch, billionaires wore capes and went rushing around trying to save the innocent from the tyrants of the world. Nowadays, the billionaires just want to watch the world burn.

I’m waiting for a long running scandal involving Elon Musk that keeps getting longer so we can call it Elongate.

BoundedContext > contains Controller > creates DataObject > puts on CommandBus > delivers to UseCase > uses Repository > retrieves Aggregate > passes to DomainService > uses AggregateRoot > uses ValueObject > eventually Infrastructure > triggers EventDispatch DDD flow in a nutshell.

Please use this new year to realise we can all start again. The past is behind. The future is ahead. We can reset. If Darth Vader could do it, then we can all do it too. May the force be with you!

“Do you expect me to talk?” “No, Mr Bond. I expect you to die!”

My new political party: Fountains, statues and monorails. Free for all. I call it Rogeria. Rights for all people and animals. Free camping rights all around the UK. Resistance to dark outside powers and dark inside powers. A constitution to prevent government intervention on peoples’ lives.

A fascinating description.

Anyone who’s done DDD in PHP, how was it? Did it make life easier than regular CRUD?

I did my usual Christmas tradition and gave a fiver to a homeless person. I don’t care what they spend it on. If we all did this then at least everybody gets a bit of attention at this time of year. That’s what I think it’s all about.

In a chef’s kitchen the cooks work together, communicate a lot, keep things on track and rely on quality for their reputation. The head chef will re(de)fine dishes relying on feedback from their fellow experts and customers alike, always sharing ideas. Each kitchen is different. Software is similar.

Building software is a fun team game where you work together, get excited, chat with stakeholders and solve the problems along with tests and refactoring. Then you celebrate at the end of the day whichever way best suits you. A high five for a typical weekday and maybe a chat and drink on a Friday.

Debugging could even be seen as the *absence* of a skill. Like saying "I'm really good at putting kitchen fires out"

There are examples of pure genius in the world of human history that just cannot be explained. The ancient Egyptians. The Beatles. With an emphasis on the latter.

We’re posting here on social media, “venting out” & writing about those who are super-rich and in control… Those who are super-rich and in control are laughing. They’re enjoying us sitting with smartphones, doing nothing but being annoyed & sharing. We do nothing but wait for a hero. #timeforheroes

Number 1 symptom of the Woke Mind Virus. You don't believe stupid racist sh*t.

Here is a pattern I like: interface FilterInterface + filter(items) class Filter1 class Filter2 class Filter3 class CompositeFilter + add(FilterInterface filter) + filter(items) FilterBuilder + addFilter1 + addFilter2 + addFilter3 + build(): FilterInterface Not just for filters.

I’m really liking BlueSky. 🙂 That is all.

Wrap IFs, FORs, SWITCHes, WHILEs etc. in small, context-related classes (for your working code) as best you can. The sooner you leave that layer of programming, the better your code will be and the happier your team will be. You’ll still need them elsewhere now and then but consider that too.

Is anyone using one database but plucking different things from different tables to make different objects for different situations? The common (CRUD) approach is 1 record per entity/concept. Is anyone dipping in and out to gain flexibility over this? E.g. A SingingUpUser and a SignedUpUser etc..?

In software we write tiny granular level IFs, FORs, list manipulations, string manipulations etc. in all the wrong places. Use low level, meaningful concepts to contain/reuse them. Make medium level concepts out of those. Make high level concepts out of those. Concepts and meaning all the way down.

@danabra.mov Dan. I want to be able to push the little panel away that tells me my post has been made or that I’ve followed someone. It hangs around too long. Is that a thing you can do or suggest to whoever can please? Thanks! Sorry if it’s strange giving customer feedback directly.
