In this talk, we will cover the design of core.async, and then move directly to exploring core.async’s capabilities. Finally, we will assemble these primitives into substantial working programs, building toward the Holy Grail of async: substantial UI application development in the browser, with no callbacks in sight.
Datalog has been a signature feature of Datomic since day one, and the 2015 releases of Datomic add additional expressiveness for hierarchical selection, disjunction, and negation. In this talk, we will cover the basics of Datomic Datalog, and then dive into the latest enhancements, both in the core language and in how Datalog fits into application code.
This talk presents Apache Spark, Spark Streaming, Apache Kafka, Apache Cassandra and Akka as supporting Lambda architecture in the context of a fault tolerant, streaming big data pipeline. We will walk through the Fault Tolerance story with these technologies to build applications, and how to easily implement and integrate them in a Scala Akka application for real-time delivery of meaning at high velocity, in highly distributed and concurrent environments.
We are experiencing a profusion of interconnected devices. Architectures are undergoing radical changes to enable better scaling and resiliency. And at the heart of all of these are several new protocols that are changing the way services communicate. A lot of interest lies with WebSocket, HTTP/2, CoAP, MQTT, XMPP, etc. What can these protocols do? What can we learn from them? And where are things going? This session will explore these questions and more.
In this session, Joanne will present principles, stories and practical suggestions on how to build a successful organizational culture that supports experimentation and learning with the goal to delivering better value for customers.
Open source hardware and digital fabrication tools are enabling a wider audience to engage in building all aspects of interactive technologies, regardless of their backgrounds. In this talk, I’ll present an overview of some of the tools of physical computing and discuss how and by whom they’re being used to create new connected devices.
We’ve entered the Ambient Computing Era and JavaScript is its dominant programing language, But a new computing era needs a new and better JavaScript. It’s called ECMAScript 6 and it’s about to become the new JavaScript standard. Why do we need it? Why did it take so long? What’s in it? When can you use it? What comes next? Answers will be given.
Our approach to programming for the past 50+ years has mostly focused on specific features of a programming language. The result has been an emphasis on “general purpose” programming languages. The next 10 million programs will not be built this way. We don’t have the time. We don’t have the money. And we can’t afford to fail as we have been.
What helps us understand the nature of network traffic? Which services are talking to one another and how does this change during failure conditions or a deploy? What helps us understand how user behavior changes over time? And which features provoked these changes? This talk will help prepare you to tackle these problems at a range of scales.
You’re ready to go with all the best Agile practices: you’ll develop incrementally and iteratively, you’ll have sprints and retrospectives, and you can’t wait to tell your clients about your velocity and show them your burndown charts. But all of your prospective clients are telling you they want firm quotes, and contracts with detailed specifications and delivery dates. How do you convince them a traditional contract is actually riskier than they think, and persuade them to instead sign an Agile (time and materials) contract?
