We show how to simplify SSL certificates using Let's Encrypt with Apache httpd on Red Hat Enterprise Linux 7.

Born of the browser wars of the 1990s, JavaScript has gone from a simple scripting language to be the most important ecosystem of the development world.

Here are 10 tips to keep in mind when reviewing code submissions that, for whatever reason, you (as a project maintainer) do not like.

Decentralizing both the application lifecycle management process as well as the related tooling is key to scaling development and meeting changing needs.

After three years of working on VS Code, we celebrate 3.8-million installations and more than 20-million downloads—two indicators that we are providing valuable VS Code extensions accepted by fellow developers.

This article describes changes that were made to the Abigail library (Libabigail) application binary interface (ABI) change analysis framework and its associated set of tools in 2018.

Learn how to use and contribute to open source projects for your development

This article shows you how to create a pull request, the first step towards becoming an active member of an open source community.

Red Hat's certification program provides validation of IT professionals' skills and knowledge using our subscription products. What is less known is that Red Hat offers certifications for developers too!

Join Red Hat OpenShift developers Krishna Raman and Dan McPherson for an interactive whiteboard, slide, and demo session where they will dive into OpenShift's architecture, internal components, APIs, and security model. If you are a systems architect interested in learning what it takes to build a Platform-as-a-Service (PaaS), this talk is for you. Curious about the code that powers OpenShift and what it takes to run a scalable and secure PaaS? This is the talk for you!

The Internet Of Things (IoT) brings the whole new challenges to the world of the messaging solutions. Gathering data from the field and delivering it to the cloud is a common task for IoT solutions. Developers find themselves struggling with field protocols on one side and data delivery protocols on the other. Eclipse Kura is a well-recognized field gateway for IoT applications. Apache Camel is a message-routing engine and a library containing a gazillion various endpoint connectors. And last, but not least, Rhiot project attempts to make the Kura and Camel developer experience even better. In this session, you'll learn how Red Hat combines Kura, Camel, and Rhiot to create rocking IoT gateway solutions.

Have you ever used an open source project? Of course you have, but have you made any contributions yourself? Filed a bug report? Submitted a patch? Have you ever started your own OSS project, or taken a closed/private project public? What licenses should you use? How do you manage contributions? How do you support contributors and still get work done? What do you do with difficult community members? In this talk we'll go over the basics of OSS: how to get involved, how to start a project, how to manage contributions. We'll discuss project lifecycles, legal CYA tips, and how to keep projects moving. You'll see the inner workings of real OSS projects, and learn how to be a better OSS user and producer.

Geert Schuring of Dutch Company Luminis talks about his latest proejct with Fuse and makes my Daughters jealous by controlling a Tinkerforge LED panel with Apache Camel.

Over the past 5 years, Jason Hibbets has been the community manager behind Opensource.com, an online publication focused on highlighting the use of open source methodologies in areas outside of technology. In this session, he’ll provide a case study of the content strategy and community-building effort for the Opensource.com publication. You’ll go behind the scenes and see the tools, metrics, and strategy that’s helped this project grow to over 600,000 page views a month. This session will: Give in-depth insight about how to build a great team. Provide details on social media and SEO strategies. Outline our community moderator program. Show metrics and results from the Opensource.com team.

The biggest inhibitor to open source contributions is developer environment configuration. Developers want prepackaged environments ready to code, with nothing to install. Some estimates indicate that nearly 100 billion gigabyte hours are lost due to configuration problems each year. What if any project could be built or debugged without installing software? We'll explore the emerging market around cloud development and how developer work spaces can be provisioned, shared, and scaled. In this session, you will: Learn about Eclipse Che and Eclipse Cloud Development, a technology stack for eliminating configuration from the lives of development teams. Hear about an opinionated git and gerrit flow that enables tested pull-and-change requests to be submitted without the overhead of project configuration. See a demo of how popular open source projects like Spring, Apache TomEE, Orbeon, and WSO2 have written their own provisioning capabilities. We'll also demo an integration with WildFly that shows you how to quickly make a contribution without installing any software.

A new era for physics is about to begin in 2015 when the recently upgraded particle accelerator infrastructure at CERN will start up again tocontinue the search for new particles. The Accelerator Controls System behind the scene enables operators to monitor and control critical (real-time) equipment and services 24x7x365. In many ways it is realized by using open source software and even open hardware. This talk gives an insight into where and how this is done and highlights concrete scenarios like ActiveMQ for fast and reliable messaging, Camel and Elasticsearch for diagnostics and White Rabbit for central timing. It also covers the experiences made by using open source software solutions during development and maintenance of in-house services in the recent years.

Keycloak is a new open source authentication server for cloud, mobile and html5. With loads of features, including single-sign on, social login, account management console, account workflows, fully featured admin console, OAuth2 and OpenShift cartridge to name a few. The first alpha has recently been released, with loads more features planned for the future. Keycloak also provides support for role based authorization and supports granting access to third party applications. This talk gives a comprehensive introduction to Keycloak and its features, as well as discuss how easily you can add authentication to your applications. There will also be an extensive live demo. Stian Thorgersen is a Senior Software Engineer at Red Hat. He co-leads the Keycloak project together with Bill Burke, and is also the security lead on another new open source project. Stian also has many years of experience in cloud solutions.

In this JBug, Tom will use an example driven format to illustrate some of the new features that have been added into Narayana recently. We will look at: 1. Why you need a transaction manager - a brief revision course 2. Using Narayana inside none-EE containers, mainly focussing on Tomcat 3. The Narayana STM library 4. Narayana and NoSQL

Microservice architectures have become popular, but we have to balance hype with reality. Microservices make it harder to manage deployments and create complex inter-service communications patterns. Learn how Open Source software built by open communities like Apache Camel, Docker, Kubernetes, OpenShift and Fabric8 can help achieve organizational goals to integrate services and establish effective continuous integration and continuous delivery pipelines. With Christian Posta -  Principal Middleware Specialist

The current hype around the Internet of Things (IoT) has led to a substantial amount of innovation thanks to open source software, open hardware, open standards, and community inspiration. In this session, we will explore how you can use open source software to incorporate the physical world (the “Things”) into your traditional enterprise IT infrastructure. We will walk the path from a typical enterprise developer’s current focus on web desktop applications to mobile and devices, specifically developer prototyping platforms like Raspberry Pi, Intel Edison, Arduino, Particle.io, and several others. Learn how to connect the physical world to your enterprise middleware backbone via sensors and actuators. == Speaker == Burr Sutter: Technologist, innovator, creator, catalyst—an evangelist, product manager, teacher, and 'internal start-up' leader with the vision to see tomorrow's technology and the ability to focus and energize the engineers who build it and the communities who use it.
