Modern software architecture is often broken. Slow delivery leads to missed opportunities, innovation is stalled due to architectural complexities, and engineering resources are exceedingly expensive.
Orkes is the leading workflow orchestration platform built to enable teams to transform the way they develop, connect, and deploy applications, microservices, AI agents, and more.
With Orkes Conductor managed through Orkes Cloud, developers can focus on building mission critical applications without worrying about infrastructure maintenance to meet goals and, simply put, taking new products live faster and reducing total cost of ownership.

Mocking is an essential part of unit testing, and the Mockito library makes it easy to write clean and intuitive unit tests for your Java code.
Get started with mocking and improve your application tests using our Mockito guide:
Spring 5 added support for reactive programming with the Spring WebFlux module, which has been improved upon ever since. Get started with the Reactor project basics and reactive programming in Spring Boot:
Since its introduction in Java 8, the Stream API has become a staple of Java development. The basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use.
But these can also be overused and fall into some common pitfalls.
To get a better understanding on how Streams work and how to combine them with other language features, check out our guide to Java Streams:
Explore Spring Boot 3 and Spring 6 in-depth through building a full REST API with the framework:
Yes, Spring Security can be complex, from the more advanced functionality within the Core to the deep OAuth support in the framework.
I built the security material as two full courses - Core and OAuth, to get practical with these more complex scenarios. We explore when and how to use each feature and code through it on the backing project.

Spring Data JPA is a great way to handle the complexity of JPA with the powerful simplicity of Spring Boot.
Get started with Spring Data JPA through the guided reference course:
Refactor Java code safely — and automatically — with OpenRewrite.
Refactoring big codebases by hand is slow, risky, and easy to put off. That’s where OpenRewrite comes in. The open-source framework for large-scale, automated code transformations helps teams modernize safely and consistently.
Each month, the creators and maintainers of OpenRewrite at Moderne run live, hands-on training sessions — one for newcomers and one for experienced users. You’ll see how recipes work, how to apply them across projects, and how to modernize code with confidence.
Join the next session, bring your questions, and learn how to automate the kind of work that usually eats your sprint time.
Regression testing is an important step in the release process, to ensure that new code doesn't break the existing functionality. As the codebase evolves, we want to run these tests frequently to help catch any issues early on.
The best way to ensure these tests run frequently on an automated basis is, of course, to include them in the CI/CD pipeline. This way, the regression tests will execute automatically whenever we commit code to the repository.
In this tutorial, we'll see how to create regression tests using Selenium, and then include them in our pipeline using GitHub Actions:, to be run on the LambdaTest cloud grid:

1. Spring and Java
>> The Joy of Mustache: Server Side Templates for the JVM [spring.io]
An intro to Mustache and Spring Boot – what more do you need?

A short history of the JCP and the many conflicts around the Java language.
>> Debugging hints for Logstash [frankel.ch]
Quick and very practical notes on getting an ELK stack working and well-formatted data into it.
And seeing how ELK stack’s my go-to whenever the option’s open, I quite enjoyed this one.
>> Tracing In Microservices With Spring Cloud Sleuth [ryanjbaxter.com]
Tracing a request across multiple systems is a critical aspect of developing a microservice system today, and this is a good starting point to using Spring Code Sleuth and a Zipkin server to do so.
>> How to implement a soft delete with Hibernate [thoughts-on-java.org]
If you’ve been working on any complex enough system, you probably had to do a soft delete at some point. It’s not hard to implement – which is one extra reason to try to get it right from the start.

A fun (and cringy) trip down memory lane. If you remember any of the older names on this list, you know how easy we have it today 🙂
>> Let’s Encrypt Everything [codinghorror.com]
Good points about encryption.
This one hits home as well, because baeldung.com is not yet running over HTTPs. That’s of course coming.
>> Elasticsearch: Adventures in scaling a multitenant platform [bigeng.io]
This is a long post – let’s start here.
It’s also chock-full of Elasticsearch goodness.
I’m using Elasticsearch daily in my client work, so I got a lot out of it. If you aren’t, you still might want to bookmark it.

3. Musings
>> Domain Fallback Mechanism In Apps [techblog.bozho.net]
A common sense solution to DNS resolution issues – having a fallback list of IPs. Clearly something that cannot be done for a web-app running in the browser – only on a native app.
Surprisingly even the top apps on the market – such as the Twitter mobile app – don’t use the technique.
>> Managing test data in end-to-end test automation [ontestautomation.com]
The age-old question of data preparation and cleanup in testing has plagued the land for eons 🙂
Maybe I’m making it sound more ominous than it really is, but we do have entire tools built around this problem, so it’s certainly not trivial.
This is a quick intro to potential approaches and solutions.
>> How to make an introduction [dandreamsofcoding.com]
Introducing people probably isn’t the top thing on my mind. That being said, there’s really only so much we can do until without the help of someone else.
Meeting people in our ecosystem can definitely be a catalyst, so it’s well worth investing some mental energy into getting better at it.
