Contract-driven development with OpenAPI 3 and Vert.x | DevNation Tech TalkRed Hat Developers
Have you ever been frustrated by developing and documenting an HTTP API? When it comes down to defining the HTTP interface between frontend and backend, have you ever had problems specifying the parameters or the shape of the body without misunderstandings? In this talk we’ll introduce you to "Contract Driven Development" (or API Design First approach), a methodology that uses declarative API Contracts to enable developers to efficiently design, communicate, and evolve their HTTP APIs, while automating API implementation phases where possible. In order to implement this methodology, we’ll show you how to develop an API contract using OpenAPI 3 and how you can easily implement the HTTP endpoints using Vert.x Web OpenAPI.
SymfonyCon Berlin 2016 Jenkins Deployment Pipelinescpsitgmbh
Currently I'm working on a flexible deployment pipeline in Jenkins where I can reuse some templates and create new pipelines within minutes. I'd like to present my solution, talk about the basics of Jenkins and explain why it's the better way to deploy with a CI server.
Building domain-specific testing tools : lessons learned from the Apache Slin...Robert Munteanu
The Apache Sling project has built a number of testing tools which aid in testing applications that are built on top of this framework - REST-based, assembled using OSGi and backed by JCR.
We will review how those testing tools fit in with domain-agnostic testing tools such as JUnit and Mockito and what the benefits and pitfalls are when building your own domain-specific tools.
Similar techniques apply to projects not using the same technology stack, so the discussion will bring value to all projects which can benefit from domain-specific testing tools.
There's been a lot of movement in the Java EE world. From the release of its 8th edition to the shift to Eclipse Foundation and recent rebranding to Jakarta EE. At the same time Eclipse MicroProfile shown up on the EE scene with the primary goal of evolving the spec towards microservice architectures.
With all these changes happening rapidly what has happened to Arquillian, the de-facto testing tool for Java EE applications?
Come to this session, you are going to explore the new and noteworthy of the Arquillian constellation. How standard Arquillian tests has been simplified as well as how microservice architecture has impacted on Arquillian offering integrations for polyglot persistence tests, contract testing or deployment tests for Docker, Kubernetes, and Openshift.
You'll learn that Arquillian is not only for Java EE.

Event Sourcing, Domain Driven Design, and Command Query Responsibility Segregation – we hear all of these technologies used together frequently, but how do they actually work together? How do you manage complex co-ordination in a CQRS system?
In this talk, we will discuss a real world example of DDD with ES and CQRS written in F# - a functional first language on the .NET Framework. We’ll take a deep dive into the F# algebraic type system that constructs the domain model. Also, the explanation of the abstract notion of a DDD aggregate root compared to the CQRS implementation of an aggregate root. Finishing with how sagas and triggers facilitate poly-aggregate communication.
From my session at DevTernity in Riga, December 1st 2015. Have you always wanted to add predictive capabilities to your application, but haven’t been able to find the time or the right technology to get started? Everybody wants to build smart apps, but only a few are Data Scientists. We had the same issue inside Amazon, so we created a Machine Learning engine that Developers can easily use. The same approach is now available in the AWS cloud. We demonstrate how to use Amazon Machine Learning (Amazon ML) to create machine learning models, deploy them to production, and obtain predictions in real-time. We then demonstrate how to build a complete smart application using Amazon ML, Amazon Kinesis, and AWS Lambda. We walk you through the process flow and architecture, demonstrate outcomes, and then dive into the implementation. In this session, you learn how to use Amazon ML as well as how to integrate Amazon ML into your applications to take advantage of predictive analysis in the cloud.
Data analysis is being used to transform businesses, increase efficiency, and drive innovation. But organizations need to perform increasingly complex analysis on their data (streaming analytics, ad-hoc querying and predictive analytics) in order to get better insights and actionable business intelligence. The growing data volume, speed, and complexity of diverse data formats make legacy tools inadequate or difficult to use. The AWS Cloud has a comprehensive portfolio of analytics services to help you process data of any volume and automate how you put that data to work for your organization. In this session we’ll see how to put those services at work on structured, unstructured and real-time data.
Writing your CV & preparing for interview - Information for tax professionalsThe SR Group
The objective of your CV is to gain you an interview either with a potential employer or a recruitment consultant, and to create a positive impression about you in the mind of the
interviewer before you meet.
It is a good idea to split your CV into four sections: personal information, qualifications, employment history and interests.
Organisations interview in many different ways both in terms of style as well as process. As an interviewee you should never assume that each interview will be structured in exactly the same way and you should always aim to improve your interview style through better preparation and understanding of the interview process. Of course, your greatest ally is the recruitment consultant you are working with who will be able to prepare you based on their knowledge of the organisation and role in question.

Talk at RubyKaigi 2015.
Plugin architecture is known as a technique that brings extensibility to a program. Ruby has good language features for plugins. RubyGems.org is an excellent platform for plugin distribution. However, creating plugin architecture is not as easy as writing code without it: plugin loader, packaging, loosely-coupled API, and performance. Loading two versions of a gem is a unsolved challenge that is solved in Java on the other hand.
I have designed some open-source software such as Fluentd and Embulk. They provide most of functions by plugins. I will talk about their plugin-based architecture.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

6. THE CHALLENGE
Write an application that consumes a REST
API.
Components must be small and reusable.
Say no to boilerplate code.
Behavior should be easy to test.
7. THE LIBRARIES
PRODUCTION
Guice | Spring
OkHttp
Retrofit
JDeferred
RxJava
MBassador
Lombok
Slf4j | Log4j2
TEST
JUnitParams
Mockito
Jukito
Awaitility
Spock

8. GITHUB API
Well documented REST API
Latest version located at
https://developer.github.com/v3/
We’re interested in the repositories
operation for now
9. QUERYING REPOSITORIES
API described at
https://developer.github.com/v3/repos/#list-
organization-repositories
Given a query of the form
GET /orgs/${organization}/repos
10. QUERY RESULT
[
{
"id": 1296269,
"owner": { /* omitted for brevity */ },
"name": "Hello-World",
"full_name": "octocat/Hello-World",
"description": "This your first repo!",
"html_url": "https://github.com/octocat/Hello-World",
/* many other properties follow */
},
/* additional repositories if they exist */
]
11. WHAT WE’LL NEED
Dependency Injection
HTTP client & REST behavior
JSON mapping
Boilerplate buster
Handle concurrency
24. Lombok - https://projectlombok.org
public class ApplicationEvent {
}
@lombok.Data
@lombok.EqualsAndHashCode(callSuper = true)
@lombok.ToString(callSuper = true)
public class NewInstanceEvent extends ApplicationEvent {
@javax.annotation.Nonnull
private final Object instance;
}
25. Lombok - https://projectlombok.org
• Reduce boilerplate source code by generating bytecode.
• Relies on APT (Annotation Processing Tool).
• Extensible but not for the faint of heart.
• Common usages already covered, i.e, POJOs, builders.
• Don’t forget to enable annotation processing in your IDE!
28. HTTP
How many options are out there to build an
HTTP client?
How many ways are there to build a REST
client?
29. OkHttp - http://square.github.io/okhttp
public static final MediaType JSON
= MediaType.parse("application/json; charset=utf-8");
OkHttpClient client = new OkHttpClient();
String post(String url, String json) throws IOException {
RequestBody body = RequestBody.create(JSON, json);
Request request = new Request.Builder()
.url(url)
.post(body)
.build();
Response response = client.newCall(request).execute();
return response.body().string();
}
30. OkHttp - http://square.github.io/okhttp
• Basic HTTP/HTTP2 Client API.
• Configuration is extensible via factory classes.
• HTTP lifecycle can be decorated via interceptors.
31. ADDING JAVA ON TOP OF HTTP
What steps do we must ensure in order to
build an HTTP/REST client?
How should HTTP error codes be handled?
How to handle connection errors?
Parsing results in format X or Y.
35. MULTI-THREADED CODE
The golden rule of UI programming:
- Everything related to UI must be
executed inside the UI thread (read/write
UI properties, paint/repaint, etc).
- Everything else must be executed
outside of the UI thread.
39. JDeferred - http://jdeferred.org
• Delivers the concept of Promises
• Promises can be chained
• Java8 friendly, i.e, lambda expressions can be used
• One shot execution.
40. REACTIVE PROGRAMMING
It’s time to embrace a new paradigm.
Reactive programming is a new name for
old and well-known concepts:
events and streams
46. RxJava - http://reactivex.io
• Implements the Observable pattern.
• Delivers dozens of operations out of the box, e.g. zip, reduce,
concat.
• Supports backpressure, i.e, when the data producer is faster than
the data consumer.
47. COMPONENT COMMUNICATION
How do you keep two unrelated
components communicated with one
another?
How do you push data down the stream
without forcing publishers to wait for
consumers?
50. MBassador -
https://github.com/bennidi/mbassador
• Configurable event bus based on annotations.
• Faster implementation than Guava’s event bus.
• https://github.com/bennidi/eventbus-performance
• NOTE: project is no longer actively maintained, fixes and features will
be slow to come.
55. Mockito - http://mockito.org
• Fluid DSL based on static methods.
• Provides support for Stubs, Mocks, and Spies.
• Mock interfaces, abstract classes, and concrete classes.
56. Jukito - https://github.com/ArcBees/Jukito
@RunWith(JukitoRunner.class)
public class SampleControllerJukitoTest {
@Inject private SampleController controller;
@Before
public void setupMocks(SampleService sampleService) {
when(sampleService.sayHello("Test")).thenReturn("Hello Test");
}
@Test
public void sayHelloAction() {
controller.setModel(new SampleModel());
controller.getModel().setInput("Test");
controller.sayHello();
assertThat(controller.getModel().getOutput(),
equalTo("Hello Test"));
verify(controller.getService(), only()).sayHello("Test");
}
}
58. Spock- http://spockframework.org
@spock.lang.Unroll
class SampleControllerSpec extends spock.lang.Specification {
def "Invoke say hello with #input results in #output"() {
given:
SampleController controller = new SampleController()
controller.model = new SampleModel()
controller.service = Mock(SampleService) {
sayHello(input) >> output
}
when:
controller.model.input = input
controller.sayHello()
then:
controller.model.output == output
where:
input << ['', 'Test']
output << ['Howdy, stranger!', 'Hello Test']
}
}
59. Spock- http://spockframework.org
• Groovy based DSL.
• Parameterize multiple methods with different argument
cardinality.
• Parameterize test method names.
• JUnit friendly (can use extensions and rules).
