During past years, the requirements for modern applications have increased from gigabytes of data to terabytes, from thousands of requests per second to millions, from seconds of response time to milliseconds, and this list can be continued. Until now, most of these problems have been solved using the Microservices architecture, but what's next? What next approach should we apply where Microservices fail? In this presentation, we will overview modern approaches to application development with Reactive and Distributed architecture and see how Vert.x help to implement such solutions.

Java9 Beyond Modularity - Java 9 más allá de la modularidadDavid Gómez García
These are the slides I used for my "Java 9 beyond modularity" at several different local meetups and conferences in Spain during 2017
Java 9 is about to reach its public release scheduled for September 2017. If we ask what are the new features that this new version will include, probably the first that comes to our head is modularity.
But java 9 brings with a lot of features beyound Jigsaw, JPMS or modularity. In this talk we will talk about at least 9 other new features that include this new version of Java that are interesting and maybe will end up being more used than the modularity itself for those who embrace the new version.
Those are changes that come to complement and improve even more the set of new tools (like Streams, Optionals, etc...) that Java 8 brought to us.
We'll take a look at small changes in language syntax (such as new ways of using try-with-resources), changes in Collections APIs and Streams, new tools like VarHandles, new APIs such as the Flow API, and As we allow the inclusion of reactive programming with Java.
Do you want to see in Java 9 beyond modularity? Do you want to have a more complete view of what you can provide? Let's take a look toghether!
Take Control of your Integration Testing with TestContainersNaresha K
Slides from my Java2Days conference talk - Take Control of your Integration Testing with TestContainers.
How easy is it to write and maintain integration tests when your system under test interacts with databases, message stores, and other external systems? It can be quite challenging, can’t it? For example, the lack of control over the setup of databases can increase the cost of integration testing. Sometimes we take the route of using an in-memory database instead of the one we employ in the production environment, making the tests less effective. With Docker containers, you can simplify this to some extent by running the setup before invoking your tests. Imagine if you get to control the database environment right from within the test code. TestContainers bring in this convenience.
TestContainers is a tool that you can invoke from your test code. It provides lightweight, throwaway instances of common databases, web browsers(Selenium tests), or anything else that can run in a Docker container. In this presentation, I walk you through how TestContainers is the most effective way to take advantage of Docker containers for integration testing. I present through several use-cases and demonstrate how TestContainers simplifies integration testing.

This is a presentation given on October 24 by Michael Uzquiano of Cloud CMS (http://www.cloudcms.com) at the MongoDB Boston conference.
In this presentation, we cover Hazelcast - an in-memory data grid that provides distributed object persistence across multiple nodes in a cluster. When backed by MongoDB, objects are naturally written to Mongo by Hazelcast. The integration points are clean and easy to implement.
We cover a few simple cases along with code samples to provide the MongoDB community with some ideas of how to integrate Hazelcast into their own MongoDB Java applications.
Futures and Rx Observables: powerful abstractions for consuming web services ...Chris Richardson
A modular, polyglot architecture has many advantages but it also adds complexity since each incoming request typically fans out to multiple distributed services. For example, in an online store application the information on a product details page - description, price, recommendations, etc - comes from numerous services. To minimize response time and improve scalability, these services must be invoked concurrently. However, traditional concurrency mechanisms are low-level, painful to use and error-prone.
In this talk you will learn about some powerful yet easy to use abstractions for consuming web services asynchronously. We will compare the various implementations of futures that are available on the JVM. You will learn how to access web services using reactive observables (RxJava), which are asynchronous data streams. We will describe how these mechanisms let you write asynchronous code in a very straightforward, declarative fashion.
JavaFX 8 est disponible depuis mars 2014 et apporte son lot de nouveautés. Gradle est en version 2 depuis juillet 2014. Deux technologies plus que prometteuses: JavaFX donne un coup de jeune au développement d’applications desktop en Java en apportant un navigateur web intégré, le support des WebSockets, de la 3D, et bien d’autres. Gradle est l’outil de d’automatisation de build à la mode, apportant de superbes possibilités par rapport rapport à maven, outil vieillissant, grâce à l’engouement de la communauté vis à vis de cet outil mais aussi par le fait de la technologie utilisée en son sein: groovy. Venez découvrir comment il est possible de réaliser rapidement une application à la mode en JavaFX avec un outil à la mode également. Bref venez à une session trendy.
Node has captured the attention of early adopters by clearly differentiating itself as being asynchronous from the ground up while remaining accessible. Now that server side JavaScript is at the cutting edge of the asynchronous, real time web, it is in a much better position to establish itself as the go to language for also making synchronous, CRUD webapps and gain a stronger foothold on the server.
This talk covers the current state of server side JavaScript beyond Node. It introduces Common Node, a synchronous CommonJS compatibility layer using node-fibers which bridges the gap between the different platforms. We look into Common Node's internals, compare its performance to that of other implementations such as RingoJS and go through some ideal use cases.

One of the new features in JavaFX 2 is a set of pure Java APIs that can be used from any JVM language, opening up tremendous possibilities. This presentation demonstrates the potential of using JavaFX 2 together with alternative languages such as Groovy, Clojure, and Scala. It also will showcase the successor to JavaFX Script, Visage, a DSL with features specifically targeted at helping create clean UIs.
MongoDB is the trusted document store we turn to when we have tough data store problems to solve. For this talk we are going to go a little bit off the path and explore what other roles we can fit MongoDB into. Others have discussed how to turn MongoDB’s capped collections into a publish/subscribe server. We stretch that a little further and turn MongoDB into a full fledged broker with both publish/subscribe and queue semantics, and a the ability to mix them. We will provide code and a running demo of the queue producers and consumers. Next we will turn to coordination services: We will explore the fundamental features and show how to implement them using MongoDB as the storage engine. Again we will show the code and demo the coordination of multiple applications.

Spring Cloud: API gateway upgrade & configuration in the cloudOrkhan Gasimov
In this presentation we walk through features of Spring Cloud Gateway and Spring Cloud Config projects, overview new features provided by Spring Cloud Gateway including advanced routing options for API services supporting parallel APIs in several versions, discuss code examples and configuration options. Once API gateway is deployed, we don’t want to redeploy it on configuration changes as well as redeploy other services upon configuration updates. And this is where Spring Cloud Config enters the game. It allows us to keep configurations in the cloud, for example in a Git repository, and once paired with tools necessary, enables almost zero-down-time configuration updates, audit of changes and parallel configurations for different environments.
While developing distributed apps, most teams are focused in delivery of business value. Sometimes, after production deployment, a few moments later, we realize that exceptions arise, time-outs blow. The system need more fault tolerance. Presentations overviews a few patterns and principles of fault and latency tolerance for such systems.
Distributed design is the way to go for most of the modern applications. However, when you have a startup with 1-2 back-end developers in a team, it’s much easier to start with a monolithic app and refactor it when necessary. Presentation covers a few patterns, anti-patterns and real-life examples from personal experience.
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
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).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
