GraphQL is a specification created by Facebook that defines a query language for fetching data from backend services. It allows clients to request specific data fields from a server in a hierarchical manner and receive only the requested data. GraphQL queries are strongly typed and introspective, allowing clients to understand the structure of the returned data. While still in draft form, GraphQL is used in production by Facebook's mobile apps and provides advantages over traditional REST APIs by being more product-centric and client-driven.

Declarative Concurrency with Reactive ProgrammingFlorian Stefan
”Everything is a stream“ - This often cited mantra indicates why Reactive Programming is such a powerful tool for handling data flows in almost every part of an application. Reactive Programming has experienced a significant growth in popularity in recent years. But its growing popularity also leads to a Babylonian confusion: the term ”Reactive“ has become overloaded and ”is now being associated with several different things to different people“ (Jonas Bonér, Viktor Klang). To understand what Reactive Programming is - and what it isn’t - this talk surveys the landscape sharpened by trends like Reactive Streams, Reactive Extensions and Reactive Systems. It then summarizes the basic principles of Reactive Programming by looking at the Reactor library and discusses examples, of how to use this library in a legacy system.

Simplifying Distributed Transactions with Sagas in Kafka (Stephen Zoio, Simpl...confluent
Microservices are seen as the way to simplify complex systems, until you need to coordinate a transaction across services, and in that instant, the dream ends. Transactions involving multiple services can lead to a spaghetti web of interactions. Protocols such as two-phase commit come with complexity and performance bottlenecks. The Saga pattern involves a simplified transactional model. In sagas, a sequence of actions are executed, and if any action fails, a compensating action is executed for each of the actions that have already succeeded. This is particularly well suited to long-running and cross-microservice transactions. In this talk we introduce the new Simple Sagas library (https://github.com/simplesourcing/simplesagas). Built using Kafka streams, it provides a scalable fault tolerance event-based transaction processing engine. We walk through a use case of coordinating a sequence of complex financial transactions. We demonstrate the easy to use DSL, show how the system copes with failure, and discuss this overall approach to building scalable transactional systems in an event-driven streaming context.
This document provides an overview and requirements for developing a Hospital Management System. It describes collecting both primary and secondary data. Key objectives of the system are to computerize patient and hospital details, schedule appointments and services, update medical store inventory, handle test reports, and keep patient information up-to-date. The system will have modules for login, patients, doctors, billing, and generating reports. It will use a relational database with tables for patient, doctor, room, and bill details.
This document discusses non-blocking I/O and the traditional blocking I/O approach for building servers. The traditional approach uses one thread per connection, blocking I/O, and a simple programming model. However, this can cause issues like shared state between clients, synchronization problems, inability to prioritize clients, difficulty scaling to thousands of connections, and challenges with persistent connections. The document explores using non-blocking I/O with Netty as an alternative.

Isomorphic React Applications: Performance And ScalabilityDenis Izmaylov
Isomorphic React applications allow code to run on both the client and server, improving performance and scalability. Server-side rendering builds HTML on the server so the page loads immediately before JavaScript loads. This improves the user experience but requires loading data asynchronously. Caching pre-rendered components and separating rendering can improve performance. Progressive rendering and Facebook's BigPipe technique can further optimize loading. Performance can also be improved through code optimizations like using direct React files and load balancing with multiple server instances.
Akka and AngularJS – Reactive Applications in PracticeRoland Kuhn
Imagine how you are setting out to implement that awesome idea for a new application. In the back-end you enjoy the horizontal and vertical scalability offered by the Actor model, and its great support for building resilient systems through distribution and supervision hierarchies. In the front-end you love the declarative way of writing rich and interactive web apps that AngularJS gives you. In this presentation we bring these two together, demonstrating how little effort is needed to obtain a responsive user experience with fully consistent and persistent data storage on the server side.

What Do Contribution Guidelines Say About Software Testing? (MSR 2025)Andre Hora
Software testing plays a crucial role in the contribution process of open-source projects. For example, contributions introducing new features are expected to include tests, and contributions with tests are more likely to be accepted. Although most real-world projects require contributors to write tests, the specific testing practices communicated to contributors remain unclear. In this paper, we present an empirical study to understand better how software testing is approached in contribution guidelines. We analyze the guidelines of 200 Python and JavaScript open-source software projects. We find that 78% of the projects include some form of test documentation for contributors. Test documentation is located in multiple sources, including CONTRIBUTING files (58%), external documentation (24%), and README files (8%). Furthermore, test documentation commonly explains how to run tests (83.5%), but less often provides guidance on how to write tests (37%). It frequently covers unit tests (71%), but rarely addresses integration (20.5%) and end-to-end tests (15.5%). Other key testing aspects are also less frequently discussed: test coverage (25.5%) and mocking (9.5%). We conclude by discussing implications and future research.
Explaining GitHub Actions Failures with Large Language Models Challenges, In...ssuserb14185
GitHub Actions (GA) has become the de facto tool that developers use to automate software workflows, seamlessly building, testing, and deploying code. Yet when GA fails, it disrupts development, causing delays and driving up costs. Diagnosing failures becomes especially challenging because error logs are often long, complex and unstructured. Given these difficulties, this study explores the potential of large language models (LLMs) to generate correct, clear, concise, and actionable contextual descriptions (or summaries) for GA failures, focusing on developers’ perceptions of their feasibility and usefulness. Our results show that over 80% of developers rated LLM explanations positively in terms of correctness for simpler/small logs. Overall, our findings suggest that LLMs can feasibly assist developers in understanding common GA errors, thus, potentially reducing manual analysis. However, we also found that improved reasoning abilities are needed to support more complex CI/CD scenarios. For instance, less experienced developers tend to be more positive on the described context, while seasoned developers prefer concise summaries. Overall, our work offers key insights for researchers enhancing LLM reasoning, particularly in adapting explanations to user expertise.

Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik
Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe.
We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved?
Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.

This presentation explores code comprehension challenges in scientific programming based on a survey of 57 research scientists. It reveals that 57.9% of scientists have no formal training in writing readable code. Key findings highlight a "documentation paradox" where documentation is both the most common readability practice and the biggest challenge scientists face. The study identifies critical issues with naming conventions and code organization, noting that 100% of scientists agree readable code is essential for reproducible research. The research concludes with four key recommendations: expanding programming education for scientists, conducting targeted research on scientific code quality, developing specialized tools, and establishing clearer documentation guidelines for scientific software.
