I'm experimenting with AI Assistants to get them to do projects my way. My approach is document how I'd like things done while I do them. Then I revert the change and let the assistant do it.

Role-playing - objects are more players of their roles than instances of their types. -- Sandi Metz #oop

"You can't build the right product if you can't build the product right. If you can build the thing right, you can live long enough to find the right thing." ronjeffries.com/xprog/articl...

As always, it's great to listen to @jbrains.ca. Are integrated tests a scam? youtu.be/j0NjFsb-at8

Mocks... Mocks everywhere... In this video Emily made me feel it's ok not to fight this particular instance of semantic diffusion. youtu.be/RvKPOjlQKyM?...

"You can draw a line around any part of your code and call it anything you like, but only when you have to maintain the tests do boundaries become real." “Hexagonal Architecture Explained” Alistair Cockburn & Juan Manuel Garrido de Paz #hexagonalarchitecture #portsandadapters #testing

The Future of Software Development is Software Developers - or why we won't be replaced by #ai anytime soon - by @jasongorman.bsky.social codemanship.wordpress.com/2025/11/25/t...

Me in 2005: let me code this whole system over the weekend. Me in 2015: let me glue these open-source projects together to confirm if the idea is worth doing. Me in 2025: let me spend a couple of hours creating a spreadsheet so I don't have to write the app.

“duplication is far cheaper than the wrong abstraction” - Sandi Metz in “All the little things” at RailsConf 2014 The quote is often put out of context to support the idea it’s always better to postpone the abstraction until there’s enough duplication. #SoftwareDevelopment #oop

The day hasn't passed yet and I think Ghostty will also replace tmux for me.

/me installs ghostty

I still can't believe I can just play this game on my mobile.

. @lunivore.bsky.social 's blog is such a great resource for #BDD related content. "Don’t start with BDD, and definitely don’t start with the tools."

You know what? DON'T hire entry-level software developers. DO use chatbots to generate as much of your code as possible. DON'T bother investing in your dev teams and dev processes. DO let their ability to comprehend code atrophy. I've got my eye on a bigger house, you see.

"There’s always more to build than we have time or resources to build—always." If you somehow started to build 10x quicker, would you fire 9/10 of your developers or would you rather start building 10x more? 🤔

Putting all your controllers in one directory and your views in another Is like putting the cortisone and hemorrhoid cream in the drawer with toothpaste because they're all tubes.

I re-read the introduction to "User Story Mapping" by Jeff Patton, and there are so many gems in this chapter alone.

The Big OOPs: Anatomy of a thirty-five-year mistake is an excellent talk. I love it when someone makes the effort to dig into the background of concepts instead of reinventing their own interpretations. Those who don't learn the past are deemed to repeat it. youtu.be/wo84LFzx5nI?...

Reading "hexagonal architecture explained" by Alistair Cockburn. I need to stop each time a driving or a driven port is mentioned and think if it's inbound or outbound. As a non native English speaker I much prefer the inbound/outbound terms.

IntelliJ plugin request: Visualise the testing strategy based on test labels/tags. Include the time it takes to run each layer.

I like this reincarnation of the testing pyramid - the testing iceberg. It shows how not all business-readable tests need to be end-to-end, or even integrated. claysnow.co.uk/the-testing-...

Thank you, @dev.to for the new badge, but I'd rather be able to save an article to update the canonical URL. What I get instead: Whoops, something went wrong: status: 500 error: Internal Server Error

Final (at least for now) batch of articles are now migrated from dev.to to my personal domain. These are from my well received event sourcing series: zalas.pl/series/event... #eventsourcing #ddd #dddesign #kotlin

I stumbled upon an opinion that in modern #dddesign the Aggregate should be freed from its constraints and the Dynamic Consistency Boundary (DCB) is the next cool thing.

Another one migrated. "Collaboration and contract tests": zalas.pl/collaboratio...

I started migrating my blog to Hugo from dev.to. I'll be doing it post by post, while revising the content. First blog post is now moved: zalas.pl/on-granulari...

I have finally automated releases of one of my open-source projects. A new release is made weekly, if the last build succeeded. Now the project is on autopilot 😎 github.com/jakzal/phpqa...

I don't know if I can go back to working in an office...

What's the best static-page generator for a blog in 2025? I went with dev.to initially as I just wanted to write. Some of the articles turned out to be valuable for others, and I'd like to host them under my own domain now on github pages.

Hm... I noticed that some of the images have disappeared from (at least) one of my @dev.to blog posts: dev.to/jakub_zalas/... Anyone else experienced this?

I'm thinking of migrating some of my GitHub actions to something that could be run locally more smoothly. I know there's nektos/act, but that's a bit clumsy. Is dagger.io what I'm looking for? 🤔 #cicd

Principle of Mutual Oblivion (PoMO): ralfwestphal.substack.com/p/principle-... Radical Object-Orientation looks a lot like functional programming. #oop #fp

My latest talk is now available. It covers a lot of different design techniques in just 60 mins! www.youtube.com/watch?v=fOF3...

A healthy take on the test pyramid. “Eviscerating the Test Automation Pyramid” cucumber.io/blog/bdd/evi...

I like when someone goes back to the source and sets the record straight. I'm also fed up with people bashing mocks without actually giving any arguments against them.

My friend Manuel Rivero has published an awesome article that I think is great 👇 codesai.com/posts/2025/0... at @codesaidev.bsky.social

I'm playing with #Kotlin coroutines, channels and flow to reproduce actor-like behaviour. Yes, I know of the obsolete `CoroutineScope.actor`. Just playing!

The upcoming Structurizr DSL v4.0.0 release will now also support relationship archetypes. 🚀 Read more at www.patreon.com/posts/122686...

After a year of dotnet core, I'm back with #Kotlin, and it's so good to be back! Something about Kotlin makes I just feel at home. Unmatched developer experience.

Living now in Central Europe is scarring and frustrating. I’m angry seeing surprised posts here from the US folks that Trumps does what he does. Is it really that surprising? Also as Polish person, we have a deep remember of Munich, Jalta “piece agreements”. That’s what’s happening now again. 1/

By bicycle, it takes about 15 minutes to get from my place to Wimbledon Village. In a supercar that's 20x as fast, it takes about 15 minutes to get to Wimbledon Village. In case you were wondering why faster code generation makes little difference to team productivity.

"I never know what test to write, requirements aren't clear." is what someone actually told me to justify their reluctance to write tests first.
