Getting around with Ansible Galaxy.
What you should try to look after when writing your own role before submitting it to Galaxy, some high-quality roles examples and some facts on Galaxy at the moment.
After explaining what problem Reactive Programming solves I will give an introduction to one implementation: RxJava. I show how to compose Observable without concurrency first and then with Scheduler. I finish the talk by showing examples of flow control and draw backs.

My personal highlights from the Reactive Summit 2017. I loved the conference from the beginning till the end and I shared some of that with my Reactive Amsterdam meetup. All content belongs to the respective speakers.
A step towards the way you write the code in React application.In this presentation, I have given introduction about React hooks. Why we need it in our react applications and describe about the two most commonly used React Hooks API useState and useEffect. I also given the links of code snippets I added in these slides
Streams, Streams Everywhere! An Introduction to RxAndrzej Sitek
Nowadays users expect real time data - tweets, messages, order confirmations etc. - the user's attitude moved to the “push" model and it is high time for us devs to make that step as well.
Reactive Extensions (Rx) is the new hot stuff amongst developers these days. It is a library for composing asynchronous and event-based programs by using observable sequences. Sounds nice?
The only problem is that it can be a bit difficult to approach initially, especially when you come from an imperative world, but once mastered it helps dealing with some common problems in a nicer and cleaner way making your code more readable and easier to maintain.
Multiple implementations of Reactive Extensions helps reusing once learnt concepts between different programming languages. The aim of this talk is to provide a quick introduction to Rx theory and potential usecases. The examples are based on RxJava - the Java VM implementation of Reactive Extensions.

The Developer Conference - CloudKit, entendendo a Cloud da AppleRodrigo Leite
In this lecture that I presented in the TDC, I will explain a brief experience using the framework CloudKit.
The problems found and the solutions to solve them.
Over the past few years, web-applications have started to play an increasingly important role in our lives. We expect them to be always available and the data to be always fresh. This shift into the realm of real-time data processing is now transitioning to physical devices, and Gartner predicts that the Internet of Things will grow to an installed base of 26 billion units by 2020.
Reactive web-applications are an answer to the new requirements of high-availability and resource efficiency brought by this rapid evolution. On the JVM, a set of new languages and tools has emerged that enable the development of entirely asynchronous request and data handling pipelines. At the same time, container-less application frameworks are gaining increasing popularity over traditional deployment mechanisms.
This talk is going to give you an introduction into one of the most trending reactive web-application stack on the JVM, involving the Scala programming language, the concurrency toolkit Akka and the web-application framework Play. It will show you how functional programming techniques enable asynchronous programming, and how those technologies help to build robust and resilient web-applications.
Once you have your Microservices setup, the most pertinent question is how to I test Microservices and ensure that all the moving parts of this distributed system stay in sync.
The presentation provides testing strategies on how to test Microservices and provides focussed understanding of using Consumer Driven Contracts (CDC) to test Microservices API. Additionally it provides pointers around how to do debug Microservices and trace the performance of individual services.
Please read the following presentations before referencing "Testing Microservices"
1. Introduction to Microservices - https://www.slideshare.net/anilallewar/introduction-to-microservices-78270318
2. Build the Microservices sample application -
https://www.slideshare.net/anilallewar/building-microservices-sample-application
Microservices architecture has recently become very popular. However, along with it advantages, it brings some challenges as well. With the growing amount of components, testing becomes one of such challenges. In most cases, a microservice is a stateful component that changes its state after a test. Here we present an approach that makes tests independent and reproducible without extra development effort.

Scala, docker and testing, oh my! mario camouJ On The Beach
Testing is important for any system you write and at eBay it is no different. We have a number of complex Scala and Akka based applications with a large number of external dependencies. One of the challenges of testing this kind of application is replicating the complete system across all your environments: development, different flavors of testing (unit, functional, integration, capacity and acceptance) and production. This is especially true in the case of integration and capacity testing where there are a multitude of ways to manage system complexity. Wouldn’t it be nice to define the testing system architecture in one place that we can reuse in all our tests? It turns out we can do exactly that using Docker. In this talk, we will first look at how to take advantage of Docker for integration testing your Scala application. After that we will explore how this has helped us reduce the duration and complexity of our tests.
Integration testing is hard, and often teams are tempted to do it in production. Testcontainers allows writing meaningful integration tests spawning Docker containers for databases, queue systems, kv-store, other services. The talk, a blend of slides and live code, will show how we are able to deploy without fear while integrating with a dozen of different datastores. Don't mock your database with fake data anymore, work with real data

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

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.

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.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

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).
