Node.js vs Play FrameworkYevgeniy Brikman

Video: https://www.youtube.com/watch?v=b6yLwvNSDck Here's the showdown you've been waiting for: Node.js vs Play Framework. Both are popular open source web frameworks that are built for developer productivity, asynchronous I/O, and the real time web. But which one is easier to learn, test, deploy, debug, and scale? Should you pick Javascript or Scala? The Google v8 engine or the JVM? NPM or Ivy? Grunt or SBT? Two frameworks enter, one framework leaves. This is the English version of the presentation.

Introduction to AkkaJohan Andrén

This document provides an introduction to Akka actors. It discusses how actors provide a model for building concurrent and distributed applications by avoiding shared mutable state and instead using message passing. Actors communicate asynchronously by message passing and handle errors through a supervision hierarchy. The document outlines several features of the actor model including load balancing, parallelization, and error handling.

Akka - A Brief IntroThomas Lockney

The actor model provides simple concurrency, resiliency, and elasticity through processing messages sequentially between actors that have no shared state. Actors receive and respond to messages to define their behavior, and can create other actors within the actor system. Key aspects include that actors are not threads, messages are processed sequentially, multiple actors can work concurrently, and exception handling is done through hierarchical supervisor strategies.

Introduction to Actor Model and AkkaYung-Lin Ho

Introducing AkkaJonas Bonér

The document introduces Akka, an open-source toolkit for building distributed, concurrent applications on the JVM. It provides a programming model called the actor model that makes it easier to build scalable and fault-tolerant systems. Actors process messages asynchronously and avoid shared state, providing a simpler approach to concurrency than traditional threads and locks. Akka allows actors to be distributed across a network, enabling applications to scale out elastically.

The Actor Model - Towards Better ConcurrencyDror Bereznitsky

The document discusses various concurrency models including shared state concurrency, message passing concurrency using actors, and software transactional memory. Shared state concurrency uses locking to synchronize access to shared resources but is prone to issues like race conditions and deadlocks. Message passing concurrency avoids these issues by isolating actors and having them communicate asynchronously through message passing without shared state. The actor model is implemented in several JVM languages including Scala, Groovy, and Java libraries. Software transactional memory provides an alternative to locking by allowing transactions to access shared memory in an isolated and atomic manner.

JavaScript has a well deserved reputation of be hard to write and debug. Put it on a mobile device and the problems increase exponentially. Mobile browsers lack all of the niceties that developers rely on to do testing and debugging including the most fundamental tool, the debugger. But it is possible to write quality JavaScript on a mobile device without relying on blind luck. In this talk I will show all of the tools and tricks that I learned in my 12 month development of the new KBB.com mobile site.

Play is a web framework for Java and Scala that provides tools for building web applications and services. It aims to improve developer productivity through features like automatic reloading of code changes without restarts, integrated error handling and views, and native support for Scala. Play uses non-blocking I/O and supports event-driven architectures for improved concurrency and scalability compared to traditional threaded models.

The Play Framework at LinkedInYevgeniy Brikman

Video of the presentation: http://www.youtube.com/watch?v=8z3h4Uv9YbE At LinkedIn, we have started to use the Play Framework to build front-end and back-end services at massive scale. Play does things a little differently: it's a Java and Scala web framework, but it doesn't follow the servlet spec; it's fairly new, but it runs on top of robust technologies like Akka and Netty; it uses a thread pool, but it's built for non-blocking I/O and reactive programming; most importantly, it's high performance, but also high productivity. We've found that the Play Framework is one of the few frameworks that is able to maintain the delicate balance of performance, reliability, and developer productivity. In the Java and Scala world, nothing even comes close. In this talk, I'll share what we've learned so far, including details of rapid iteration with Java and Scala, the story behind async I/O on the JVM, support for real time web apps (comet, WebSockets), and integrating Play into a large existing codebase.

AI Changes Everything – Talk at Cardiff Metropolitan University, 29th April 2...Alan Dix

Talk at the final event of Data Fusion Dynamics: A Collaborative UK-Saudi Initiative in Cybersecurity and Artificial Intelligence funded by the British Council UK-Saudi Challenge Fund 2024, Cardiff Metropolitan University, 29th April 2025 https://alandix.com/academic/talks/CMet2025-AI-Changes-Everything/ Is AI just another technology, or does it fundamentally change the way we live and think? Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater. At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts. At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.

TrustArc Webinar: Consumer Expectations vs Corporate Realities on Data Broker...TrustArc

Most consumers believe they’re making informed decisions about their personal data—adjusting privacy settings, blocking trackers, and opting out where they can. However, our new research reveals that while awareness is high, taking meaningful action is still lacking. On the corporate side, many organizations report strong policies for managing third-party data and consumer consent yet fall short when it comes to consistency, accountability and transparency. This session will explore the research findings from TrustArc’s Privacy Pulse Survey, examining consumer attitudes toward personal data collection and practical suggestions for corporate practices around purchasing third-party data. Attendees will learn: - Consumer awareness around data brokers and what consumers are doing to limit data collection - How businesses assess third-party vendors and their consent management operations - Where business preparedness needs improvement - What these trends mean for the future of privacy governance and public trust This discussion is essential for privacy, risk, and compliance professionals who want to ground their strategies in current data and prepare for what’s next in the privacy landscape.

Building 10x Organizations with Modern Productivity Metrics 10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’ Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them. But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?
