How Micronaut Practices Developer Productivity Engineering

Online event

The Micronaut project is a modern, JVM-based, full-stack framework for building modular, easily testable microservice and serverless applications. Get the Lowdown on how the Micronaut project teams do Developer Productivity Engineering (DPE). In this Webcast we chat with Cedric Champeau, a Consulting Member of Technical Staff at Oracle Labs, and Sergio del Amo Caballero, a Micronaut Product Development Lead at Object Computing Inc. about their experience improving developer productivity for 40+ Micronaut projects. Cedric and Sergio will share their DPE wins and the productivity insights gained to ultimate improve build times by 50%.

Ballerina: A language to develop, consume and combine network services

Ballerina is a modern, general-purpose programming language that makes it easy to develop and consume network services. It's a pragmatic language with familiar C-style syntax combined with explicit error handling, static types, concurrency safety to make programs reliable and maintainable. The current compiler produces JVM bytecodes; hence, it can fit anywhere Java is used. Also, the Java interoperability in the language makes Ballerina compatible with most existing java libraries.

Typically, applications reuse code by linking software libraries. But today, more and more applications reuse code by consuming services over the network, typically JSON over HTTP. APIs that matter are primarily network APIs. This shift to the cloud has changed programming, and there is a need for new abstractions in languages to improve developers' productivity.

Ballerina offers network primitives in the language to simplify developing and deploying services in the cloud. Services with resource and remote functions, clients, and interactions are higher-level concepts in the language designed to hide the complexities of working over the network. The syntax and semantics of these abstractions are designed to maintain source-diagram duality, enabling developers to visualize any ballerina program as a sequence diagram. Ballerina also simplifies deploying Ballerina code onto the cloud, allowing those without in-depth knowledge about Kubernetes to write the logic and deploy that code onto cloud platforms such as Kubernetes.

Bio:
Sameera Jayasoma is the head of architecture for Ballerina at WSO2. He is one of the designers of the Ballerina language and platform capabilities. He's been working at WSO2 for 14 years and contributed to WSO2 Carbon and Update Manager projects. He likes to engage in wildlife and landscape photography and enjoys pacific northwest hiking.

"One of the most interesting aspects of the world is that it can be considered to be made up of patterns"
Norbert Wiener (1940s)

We are entering a new and long-tail phase of software development with Machine Learning (ML). ML, a subset of AI, is the ability of a machine to produce accurate results for a particular problem without any explicit programming. These predictive results are derived from recognizing patterns in large data sets.

We are effectively giving machines the ability to gain experience.

This megatrend affects our applications, software tools, data structures, systems architecture, new hardware approaches, business processes, organizational interactions, enterprise strategies, government behavior, geopolitical strengths, ethics, data privacy, etc. In essence, ML is an inflection point for computing, enterprises, countries, humanity, and civilization.

We’ll explore some basic ML use cases, take a look at JSR #381 (Visual Recognition for Java), and then dive into issues, strategies, and the near-term and long-term directions of ML.
