Dos and don'ts with react hooks. An opinionated approach
Daniel
Espino Garcia
,
Software Design Engineer at Mattermost
Keywords:
javascript react reactnative hooks

Function components on React introduced hooks, a completely different approach to how you deal with the component lifecycle. This has led to many discussions on when and where to use hooks.What values should be memoized with useMemo? When is needed useCallback? What should go in the dependency array? Why using useReducer if it does the same as useState? This talk tries to give a swallow look at the trade-offs of using different callbacks and advice on when to use them, with practical examples.

Java's Project Loom & Co - the end for reactive programming?
Jan
Weinschenker
,
Architect and Senior Consultant
Keywords:
reactive programming, java, jvm, threads, loom, performance, project loom, virtual threads

More often than not, modern and powerful software will at some point have to deal with processing a large amount of events and data. 100 incoming requests per minute can suddenly turn into thousands or more per minute. Appropriately sized hardware can deal with heavy load, if it is available. Well written software intelligently utilizes the available resources, such as memory, network, threads, etc.The JVM left a lot to be desired here. Especially when it came to managing a limited number of threads. They were an expensive commodity and concurrency is always difficult to implement. Reactive frameworks such as WebFlux, RxJava or Kotlin's coroutines closed this gap. However, these frameworks are cumbersome. They take some time to really master.But Project Loom, introduced with Java 21, offers virtual threads as a native Java feature to solve this problem. I will show how the new Java features compare to established reactive ways. Do they mean the end for reactive programming?

Leveraging Storybook for Component Driven Development outside of your classic Component Library.
Emma
Britnor
,
Senior Software Engineer, Bloomberg
Keywords:
React, Storybook, React Testing Library

Component Driven Development focuses on building your UIs by starting with the individual components to then compose later into your pages. Let’s dig into how we can utilise Storybook to promote this paradigm, in the environment of large web apps that many of us work with daily. I’ll take you on a journey from component creation, discussing best practices for API design, how to then write Stories to document your flexible component API and then compose those stories directly in your tests with React Testing Library to encourage UI driven testing. These are usually best practices we associate with traditional component libraries but complex web apps have a lot to learn from adopting this approach in setting them up for success.

Improvement of Object Orientation through the Use of the Mirror Pattern
Dominik
Galler
,
Director IT Excellence @esentri AG
Keywords:
Java, Mirror Pattern, OOP, Reflection

Developer teams are encouraged to solve basic functions centrally and transparently to save effort in repetitive tasks. One such approach is the use of the Mirror Pattern (bracha.org/mirrors.pdf).Initially, this presentation introduces the fundamentals of the Mirror Pattern. It discusses how a minimal Mirror Pattern can be established in a Java project and the prerequisites needed. The pattern is theoretically motivated and then demonstrated through a minimal reference implementation. Based on the example implementation, potential application areas are explored with examples, focusing on enhancing object orientation. Meta-programming via the Mirror can help reduce procedural code (often found in Spring applications) and enable developers to create intuitive, structured, and more reusable structures. Since there are no silver bullets, risks and experiences from over two years of practical use in projects are also considered.

Fake it until you `make it`. API Integration Testing with testcontainers and WireMock
Oleg
Nenashev
,
Community Builder at WireMock, CNCF/CDF Ambassador, Jenkins maintainer
Keywords:
testcontainers, wiremock, api

Testcontainers has become one of the most popular tools for software integration testing. If you can put your system-under-test into a container, Docker compose cluster or a pod, this is what you're likely to use. If your target isn't ready, not containerizable or just too heavy for testing as is, you can always use mock testing frameworks, e.g. WireMock or MockServer in the JVM ecosystem. Can you combine both approaches? Sure! In this talk, we will classify integration testing and discuss areas for WireMock and Testcontainers, and discuss which tool to choose for each use-case. And why not both? We will discuss putting WireMock into Testcontainers, and getting best from them thanks to the new WireMock modules for Testcontainers. Last but not least, we will see how to put WireMock in front of the Testcontainers or your real system to do deeper tests or even chaos engineering. P.S: We will focus on the Java, Golang or Python examples, but the same approaches can be used everywhere

How to Create New RxJS Operators
Mohammad-Ali
A'râbi
,
Backend Engineer at Jodel | Docker Captain | Snyk Ambassador
Keywords:
RxJS, TypeScript

RxJS has a flexible implementation comparing e.g. to RxJava, separating the operators from the observable object itself. This allows other developers to create their own operators and even publish them as third-party libraries. This is the case e.g. for the RxJSx library containing operators for dealing with arrays and tuples.In this talk, we will introduce the RxJS operators ecosystem, draw some examples from RxJSx to showcase how to use operators from a third-party library, and finally showcase how one can create their own operators.

In this session, I will highlight one of the most reliable and efficient ways of software development for companies and teams of any size regardless of their architecture, technology stacks, and frameworks.Have you ever used Ruby on Rails with its scaffolding system? Or maybe Laravel with its own code generator? There is always something that helps you to write less code - nuxi, go-swagger, Hygen, and many others... but does it really?Everybody knows "code-first" or "design-first" and even the "specification-first" approaches when we talk about microservices and APIs, but what if we can expand it to the whole system not only for service communication, let's dive in!We will be focused on how specifications and proper code generation can help engineers with:- reducing the risks of bugs and misconfiguration, - designing applications regardless of framework tool limitations,- writing less boilerplate code.Finally, and most importantly - how to start using this approach today.

Statistically 70% of all IT-projects worldwide cannot be classified as "successful". Did you know that? And the crazy thing is that this figure has remained unchanged for the past 20 years, despite the fact that technology is constantly improving. The reasons: poor communication, changing requirements, unrealistic expectations and much more. Hardly any of these reasons have anything to do with technology, as it is essentially down to a lack of soft skills. Paradoxically, too much focus on technology leads to poorer results and also has another side effect: A lack of soft skills is also the main reason for job frustration, as 94% of HR managers say that employees with stronger soft skills are more likely to be promoted than employees with more years of experience but weaker soft skills. Sounds familiar?Pierluigi is the CEO of Utterskills, an e-learning academy for soft skills in IT and in his talk he will give some quick wins and an overview of the most important soft skills in IT.

How microservices become autonomous services.Microservices have been used more and more frequently in recent years. The use of many smaller services has made the use of synchronous communication increasingly difficult and complex.This is because synchronous communication ensures close coupling between the individual services and can ensure that if one service fails, a number of others fail at the same time.Typical resilience patterns such as: Circuit-Breaker, Retries, Service Meshes, etc. in turn increase the complexity of the overall system and also only partially solve the real problem. In this presentation, I will show how an event-first mindset can be used to design entire systems in an event-driven way.How microservices become autonomous services that are completely separate from each other and only communicate with each other via events.And how developers can use serverless and FaaS to focus on what is important: delivering business value.

AI is on the rise and will, inevitably, help developers to be more efficient.But it is not only developers who benefit from these tools; it's hackers too. AI doesn't care if you are a defender or an attacker. This means bad actors can leverage the amazing capabilities of AI tools to write exploit code – even if they are not full-stack developers or penetration testers. This is concerning and underscores why code security is critical for the safety of society and organisations.When used responsibly, AI can help solve the greatest obstacle to successful software security programs: the imbalance that exists between the effort developers spend finding flaws and the time to fix them.In this session, we will write an exploit for a few publicly know vulnerabilities and demonstrate how AI can help prevent 'bad' code from becoming a bigger issue.

Several studies shown that round 80% of our applications consist of other people's code. With using any 3rd party package (e.g. NPM, Maven, Cargo, NuGet, PyPi) that is developed by others, we also put a lot of trust in it, which might result in bigger security problems later. Would it not be nice if there is a better way to review a package for security? An easier way to perform an assessment based on certain aspects of the package that will tell you more about the package its software security. With the introduction of Scorecard project the Open Source Security Foundation (OpenSSF) exactly tries to achieve that. In this session we start out with different area's covered by of OpenSSF Scorecard, like how well it's maintained, does the build have dangerous workflows, and does the project use other security tools to check for problems?. All combined will give us the ability to assess a 3rd party package its security posture more easily and improve our own application security.

Hibernate is the defacto standard persistence for Java database apps. It was built when Java apps and database systems were monoliths. The cloud, microservices and serverless have changed Java dramatically, but persistence is still the same. Now AI is making its way into Java and AI requires uncompromising performance. EclipseStore was built to be the Java persistence for the cloud and AI. It enables databaseless in-memory data processing by using Core Java only. While databases use database-specific data structures or formats, EclipseStore supports the real Java object model. The engine enables seamlessly mirroring any Java object graph of any size and complexity into any object storage such as AWS S3. This leads to 3 main benefits: 1) highest performance, microsecond response and query time, up to 1000x faster than comparable SQL queries,2) 96% cloud database cost savings, 3) Radically simplicity, only one data model, no expensive mappings or data conversion.

Head of Software Engineering at Chrono24, Founder at Sparkteams
Keywords:
Scaling Agile, Organizational Design, Team Topologies, unFix

Scaling agile methods to large tech organizations doesn’t come naturally. While established frameworks like Nexus, Scrum@Scale or SAFe provide methods and processes to scale agile, they often feel clumsy, bureaucratic, and – actually – unagile. Recent approaches, such as Team Topologies and the unFIX patterns offer a different take on the problem. In our talk, we share firsthand insights on shaping an organizational structure that scales agile practices as well as our struggles and learnings along the way. We will guide you through our thinking processes and show how and why we arrived at our current organizational structure, which allows us to build successful products in a fast and user-centric way while ensuring sustainable employee satisfaction.

This talk explores the rapidly evolving landscape of modern data architectures that build and used for analytics purposes. They continually adapt practices and tools from software engineering. We will explore the growing influence of software engineering within the data ecosystem. Speaking of software engineering: the integration of analytics systems with the transactional/operative systems will also be taken into account. Typical scenarios and contextual factors of different architectural approaches we will also be discussed. We take a look into recent developments such as Data Mesh and Data Lakehouse, the ELT pattern, Cloud DWHs and theirlike. Additionally, I provide insights into the practical implementation of these architectures using tools and technologies commonly found in the “Modern Data Stack.”

Keywords:
test impact analysis, test gap analysis, pareto-optimization of tests. fast feedback from slow-running test-suites.

When a system has "grown historically," this often applies to the tests as well: they run for too long but find too few bugs. The reason is that such test suites often test too much and too little at the same time. They test too much because they include tests that incur costs but provide little added value compared to similar tests. They test too little because important functionality remains untested.In the talk, I will present analyses mine data from your repos (version control, issue tracker, test coverage etc) to uncover these issues: Pareto optimization of test suites and test impact analysis identify the tests that currently have the best cost-benefit ratio. Test gap analysis reveals which code changes are still untested, indicating missing tests. By doing so, these analyses provide us as developers with effective tools to understand and improve our test architecture. For each analysis, I outline its research background and show practical examples from large systems.

The dream of communicating with computers using natural language has been around for almost half a century. Voice user interfaces (VUIs) are already available in the consumer sector through Alexa or Siri.This talk will examine how web applications can be expanded to include a voice interface consisting of speech synthesis and recognition based on current best practices from science for VUI. An example application will be used to demonstrate the existing possibilities.A particular concern of this talk is to address the limitations of the current W3C standard WebSpeech API. The non-functional requirements of availability on different system environments, data security and offline capability will be analysed in more detail. The source code and documentation of Webkit, Chromium and the Gecko engine are included in this analysis. Finally, an outlook is given on the challenges for VUIs on the web for the next decade.

In this case study, I will guide you through the implementation project of an AI-driven optimisation tool in the production chain of a large German manufacturer. I was part of a team made up of IT strategy and global AI executives. Together we worked through a variety of challenges that can occur in a company with over 200,000 employees.The initial situation was characterised by a lack of clear strategic direction and a culture of experimentation. One of the biggest obstacles was the lack of a data strategy, coupled with reluctant management and the unwillingness of various areas of the organisation to provide necessary data. In this talk, I will discuss why a team of data scientists and machine learning engineers alone is not enough. I will highlight the various organisational obstacles that can arise and how to overcome them. The talk will also emphasise the importance of a structured organisation and a comprehensive strategic approach to AI.

Progressive Delivery in Kubernetes
Carlos
Sanchez
,
Principal Scientist at Adobe
Keywords:
kubernetes, argo

Progressive Delivery makes it easier to adopt Continuous Delivery, by deploying new versions to a subset of users before rolling them to the totality of the users, and rolling them back if not matching some key metrics, using techniques like feature flags and canary deployments.For workloads running on Kubernetes it is very easy to adopt Progressive Delivery using Argo Rollouts. At Adobe Experience Manager we deploy over 10k customer services to Kubernetes. Changes can occur multiple times per day both internal and from code. A new feature can work fine for 99% of customers but still affect the other 1%, and detecting this just from tests is costly.We will show how to implement a Progressive Delivery pipeline with Argo Rollouts to improve the reliability of the service and prevent regressions. It allows the protection of the service and automation of roll backs to a previous version if needed. This allows for faster delivery with more confidence.

When we talk about leadership, we say that leaders need to delegate, they need to empower people, they need to inspire and motivate those they lead. What we rarely talk about is the other side of leadership, the hard truths, how easy it is to say to delegate, how hard it is to actually do, how easy it is to say you need to inspire people, how hard it is to actually do, how easy it is to say you need to confront difficult situations, and yet how hard it is to actually do so.In this talk, we're going to examine what the consequences of not taking these actions are, and how by avoiding these problems, we not only are kicking the can down the road, but ending up potentially hurting more people than we ever intended to.

ML Engineer at Meta
Keywords:
ML, Semi-Supervised Learning, Artificial intelligence

Semi-supervised learning, an innovative approach in machine learning, strategically positions itself between the realms of supervised and unsupervised learning. This methodology uniquely utilizes a combination of a small portion of labeled data and a substantially larger set of unlabeled data for model training. Its significant advantage lies in scenarios where gathering a fully labeled dataset is prohibitively costly or logistically unfeasible. By blending the directive nature of labeled data with the extensive insights of unlabeled data, semi-supervised learning offers a practical, cost-effective solution for comprehensive model training, especially in data-scarce environments.

As of late, a number of key people in the IT industry have voiced their concerns about Cloud costs. Cloud costs have been steadily rising, with the basic experience being offered by the likes of Amazon and Google not changing much, if at all. We've decided to test out a migration of a part of our applications to a bare metal machine (physical DELL rack units of our own), set up completely by ourselves, from scratch. From kubernetes, CI/CD pipelines, disk redundancy, to docker registry, Github Actions, etc.We've now been running this set up for about 60 of our applications and have seen a 80% decrease in costs, with the bare metal and data center costs being redeemed within just 2 months of leaving the Cloud (Amazon specifically).We'd love to share our journey of our bare metal migration!

When your application becomes more popular and receives more traffic, you can just add more stateless application server. But for the database, this is more complicated - scaling systems with state is always complex.Articles and blogs never explain the different approaches and their shortcomings of horizontal database scaling solutions reasonably - most often, they just try to "sell" a specific approach. But each of them has an impact on your application, and you need to build it with these constraints in mind. Covered in the talk will be:* Tasks to do before any scaling* Scaling-Up as a simple first approach* Multi-Master-Replication* Replication* Sharding
