Using Ruby Beneath a Java API
•
0 likes•791 views
My JavaLand talk with title: Using Ruby Beneath a Java API Ruby is a programming language focused on simplicity and productivity. JRuby is an implementation of the Ruby language on the Java Virtual Machine (JVM). Does it make sense to integrate Ruby libraries (Gems) with Java so they can be used transparently within any JVM-based application? Absolutely! With the diversity and innovation in the Ruby ecosystem and the popularity of polyglot programming on the JVM, it's a great fit. In this presentation, we'll explore several ways to invoke Ruby from Java, including how variables are transferred, how to adapt to data types that only exist in Ruby, how to create Java interfaces to wrap Ruby code and, finally, how to bundle Ruby Gems alongside Java code in a jar file using Apache Maven for publishing to Maven Central. As a practical example, we'll examine AsciidoctorJ, a library that provides a Java API to the Ruby-based Asciidoctor library. You'll leave the presentation with the knowledge you need to leverage JRuby to integrate any Ruby Gem into your JVM-based application.

Any resistance is futile, infrastructure bugs will be assimilated
what Arquillian is, and how it works and deep dives into the new extension called Cube which is an extension that can be used to manager Docker containers from Arquillian. With this extension you can start a Docker container with a server installed, deploy the required deployable file within it and execute Arquillian tests. The key point here is that if Docker is used as deployable platform in production, your tests are executed in a the same container as it will be in production, so your tests are even more real than before.
Version Control Done Right
Presented at ACCU 2012, an modern overview of version control systems, and best practices for using them on your projects.
As ever, these slides would benefit from a Pete jumping about in front of them.
Mocks, Stubs and Fakes. ¿What Else?
Through the use of build pipelines, Continuous Delivery will enable faster and more frequent build, test and deployment cycles of software.
To ensure that what you are delivering has the required quality: how do we build a continuous delivery pipeline in the real world and how do we correctly implement tests?
Testing Polyglot Persistence Done Right
Data storage is one of the most crucial parts of any applications, and we use many different tools and tricks to keep it in a good shape. We frequently use both old school relational systems with new approaches commonly known as NoSQL. We write sophisticated queries and use optimization techniques to give our end users the greatest possible experience.
So why is persistence very often skipped in the testing efforts? Is it really that complex and painful to setup? During this talk we will have a closer look at Arquillian Persistence Extension together with NoSQLUnit. These tools remove that burden and boilerplate to make you a happy and productive programmer again! Join this session and see for yourself that writing tests for your data storage logic is as easy as writing normal unit tests!
Kubernetes Native Java
Kubernetes is becoming the de-facto platform to deploy our application nowadays. But this movement also implies some changes in the way we code our applications. Before this change, we just developed a monolith application where everything was up and running up front, now we are breaking down this monolith into (micro)services architecture and everything is interconnected with the network. Although it might seem easy, done properly is not an easy as there are some challenges to address that was not in a monolith architecture.
In this session, we’re going to start discussing what are these challenges (ie fault tolerance, service discovery, open tracing, or health checks) and demonstrate how they can be solved using Eclipse MicroProfile specification.
Come to this session to learn how to develop a successful Kubernetes-Native application using Quarkus, a Java ecosystem way to develop cloud-first, container-native, serverless focused and Kubernetes optimized.
Reactive Programming for Real Use Cases
Probably you are curious about this thing called Reactive Programming. Reactive Programming is another programming paradigm that in most of the cases, we are not used to coding in our day-to-day work, as the imperative way is the common one. This makes learning and thinking in a reactive way harder. One of the main problems I have found when learning and reading material about Reactive Programming is that they never tackle enterprise use cases. In this session, we are going to skip the cute ideas that are normally part of a reactive programming talk and focus on how to use it in the real world. Don't be the last developer to board this train and move your reactive skills from novice to expert.

Microservices testing and automation
DevOps has grown in popularity in recent years, particularly in (software) companies that want to reduce lead time to be measured in days/weeks instead of months/years. If you want to make sure your software does the right things and does things right, you need to test it implacably. The big problem is that companies see is the testing phase as the bottleneck—and it is—of the process slowing down product release. To change that, we need a new way of testing our applications, making the release process of an application a testing process as well and involving the QA from the beginning within the team. QAs are not a separate team anymore (DevTestOps). How is the testing pyramid affected? In this session, we will not only describe, but actively demonstrate several techniques that you can use immediately to start testing in production and speed up your release cycle to unimaginable limits.

Supersonic Subatomic Java
Java was born in the mid-90s, the era of TLC and Boyz II Men, long before the rise of Linux server virtualization and the Linux container.
We took great pride in running Java applications for weeks if not months without restarts and Java assumed the whole computer belonged to itself, that it could consume all available memory and CPU. In this presentation, we will demonstrate the problems associated using Java for "microservices", and how the open source ecosystem is working to insure the future of Java by being cloud first, container native, serverless focused and Kubernetes optimized. This is where GraalVM meets Quarkus, bringing server-side and enterprise-capable Java to enable you to build truly cloud native apps
From DevTestOops to DevTestOps
DevOps is growing in popularity in last years, particularly in (software) companies that want to reduce its lead time (time to business value from idea to production) measured in days/weeks instead of months/years?
If you want your software to do the right things and do these things right, you need to test it implacably.
The big problem is that companies see (and it is) the testing phase as the bottleneck of the process slowing down product release. To change that, we need a new way of testing our applications, making the release of an application a testing process as well, and involve QA since the beginning within the team. QAs are not a separate team anymore (DevTestOps).
What is the role of QAs in this new approach? How is the testing pyramid affected? How you can fail on trying to speed up release frequency?
In this session, we will not only describe but also actively demonstrate several techniques that you can use immediately following the session for testing applications like unicorns.
Istio service mesh & pragmatic microservices architecture
Microservices architecture has changed how companies develop and deploy applications. This change has affected testing process as well. New techniques have emerged and others have been enhanced. Does your organization wish to achieve unicorn like speed? With N deploys per day? Or a lead time (time to business value from idea to production) measured in days/weeks instead of months/years? In this session, we will not only describe how to use Istio and Kubernetes but actively demonstrate 3 specific techniques that you can use immediately following the session.
Currently, Istio is gaining a lot of traction as service-mesh implementation for Kubernetes. In this session, we are going to explore how to install Istio, and how to use it to release new versions of our services correctly.
Zero Downtime Deployment in Microservices era
ou joined the DevOps movement and want to release software even faster and safer. You started reading about Advanced deployment techniques like Blue-Green Deployment, Canary Releases or Dark Shadow Technique. But how do you implement them without disrupting your users in production? With Zero Downtime! This is easy with your code, but what about ephemeral and persistent states? Most of the examples out there does not tackle this scenario (which is the most common in real systems). Come to this session and you’ll learn in a practical way how you can achieve zero downtime deployments applying advanced deployment techniques for maintaining the ephemeral and persistent state of your microservice application.
Service Mesh Patterns
As we start to go toward cloud-native infrastructure and build our applications out of microservices, we must fully face the drawbacks and challenges to doing so. Some of these challenges include how to consistently monitor and collect statistics, tracing, and another telemetry, how to add resiliency in the face of unexpected failure, how to do powerful feature routing (ie feature graduation, tap compare ) and much more like securing your services correctly.
Service mesh, in general, helps developers solve this in a non-invasive way.
In this session, we'll show how you can take advantage of these capabilities and show you some patterns that you can implement easily with a service mesh to make your delivery to production smoothly and without surprises.
We expect most developers haven't adequately solved for these issues, so we'll take it step by step and build up a strong understanding of Istio and its patterns, harness its power in your production services architecture.
Supersonic, Subatomic Java

KubeBoot - Spring Boot deployment on Kubernetes
Have you ever thought how to deploy Cloud Native Java Applications (Spring Boot) on Kubernetes? Kubernetes has now become a de-facto standard for deploying Cloud Native Applications, but still, there is the myth that they are not ready for Java workloads. The aim of this session is to break that myth to show Kubernetes is well suited for Cloud Native Java applications. The session explores the cloud native characteristics such as Discovery, Blue/Green Deployments, Elasticity, Canary Deployments, Resiliency, Pipeline(CI/CD), Authentication etc., becomes implicit characteristics to your Spring Boot Java applications that are deployed on Kubernetes In this session, we will see how to build, debug, deploy and discover Spring Boot applications on Kubernetes, covering in-depth details of the tools, libraries, and platform that could be used to make your spring boot deployment smooth and easy.

Testing XXIst Century
Microservices architecture has changed how companies develop and deploy applications. This change has affected testing process as well. New techniques have emerged and others have been enhanced.
Come to this session to learn about service virtualization, contract testing or testing in production to increase deployment velocity from 1 week to N times per day or deploy each service independently without worrying about breaking the compatibility between services anymore.
Arquillian Constellation
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.
Testing for Unicorns
One of the most important benefits of automated testing is to ensure a fast and safe code refactoring to evolve our system architecture. The main problem is how to write tests that are easy to write, easy to follow and not time consuming during development nor execution time. In this session, we are going to explore some powerful Java testing libraries that will help you write better (unit) tests focusing on the main Unicorns architecture challenges such as validating microservices endpoints, remote calls to other microservices or just asynchronous/reactive code.
Live Long and Prosper to Monolith
Nowadays everyone is talking about microservices and how cool they are. That's true, but not all business needs to move to microservices, you can still use monolith architecture and make it more fashion by applying some of the design/elements that you've learned from microservices architecture. Can you use circuit breaker pattern, service isolation, event-driven and non-blocking application, cloud-native approach or zero downtime deployment in monolith architecture? Is it worth? The answer is YES!!!. Come to this session to learn how to make your Java monolith applications attractive again by borrowing some of the principles of microservices architecture.
Testing in the 21st Century (ExpoQA)
Microservice architectures have changed how companies develop and deploy applications, and have therefore in turn affected the testing process as well. New techniques have now emerged and others have been enhanced, while old testing techniques (used in monolith) drive us to a dead-end when we try to apply them to a microservices architecture.
In this master class, Alex Soto will introduce some testing techniques, such as service virtualization, contract testing and testing in production to increase deployment velocity from 1 week to N times per day and deploy each service independently without worrying about breaking the compatibility between services. He will show you several examples in Java but will also point out resources for other languages as well.
After this theoretical and live code master class, you'll understand how to test microservice architectures and reduce the friction between trying to apply old testing techniques to a new paradigm.

Microservice architectures have changed how companies develop and deploy applications, and have therefore in turn affected the testing process as well. New techniques have now emerged and others have been enhanced, while old testing techniques (used in monolith) drive us to a dead-end when we try to apply them to a microservices architecture.
In this master class, Alex Soto will introduce some testing techniques, such as service virtualization, contract testing and testing in production to increase deployment velocity from 1 week to N times per day and deploy each service independently without worrying about breaking the compatibility between services. He will show you several examples in Java but will also point out resources for other languages as well.
After this theoretical and live code master class, you'll understand how to test microservice architectures and reduce the friction between trying to apply old testing techniques to a new paradigm.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
