The Coderland booth at the recent Red Hat Summit was all about serverless computing as implemented in the Compile Driver. If you haven’t gone through that example (you really should), that code creates a souvenir photo by superimposing the Coderland logo, a date stamp, and a message on top of an image from a webcam. We thought it would be fun to build a Raspberry Pi version for the booth so we could offer attendees a free souvenir. Here’s a look at the finished product:

I recently had the opportunity to speak at Red Hat Summit 2019. In my session, titled “Vert.x application development with Jaeger distributed tracing,” I discussed how scalable event-driven applications could be built with Eclipse Vert.x, a Java Virtual Machine toolkit for building reactive applications.
Thanks to many developer tools, creating these applications is no longer the most effort-consuming task in IT. Instead, we now have to understand how parts of our application function together to deliver a service, (across dev, test and production environments). This can be difficult because, with distributed architectures, external monitoring only tells you the overall response time and the number of invocations, providing no insight into the individual operations. Additionally, log entries for a request are scattered across numerous logs. This article discusses the use of Eclipse Vert.x, distributed tracing, and Jaeger in the context of this problem.

Getting started with distributed tracing can be a daunting task. There are many new terms, frameworks, and tools with apparently overlapping capabilities, and it’s easy to get lost or sidetracked. This guide will help you navigate the open source distributed tracing landscape by describing and classifying the most popular tools.

Millions of developers worldwide want to learn more about serverless computing. If you’re one of the lucky thousands attending Red Hat Summit in Boston May 7-9, you can gain hands-on experience with the help of Burr Sutter and the Red Hat Developer team.
Guru Night is a BYOL (bring your own laptop) event taking place Wednesday, May 8 from 5:00 p.m. to 8:00 p.m. at the Boston Convention and Event Center in ML2 East-258AB. (Doubtless there will be a map to show you where or what ML2 East etc. is; we have no idea.) Head to the signup page and fill out your details now.
TL;DR: Beer and pizza will be served.
We felt compelled to point that out. But read on.

Red Hat Summit 2019 is rocking Boston, MA, May 7-9 in the Boston Convention and Exhibition Center. Everything you need to know about the current state of open source enterprise-ready software can be found at this event. You’ll find customers talking about their experiences leveraging open source in their solutions, creators of open source technologies you’re using, and hands-on lab experiences relating to these technologies.
This hands-on appeal is what this series of articles is about. In previous articles, we looked at labs focusing on Red Hat Enterprise Linux, Integration and APIs, and cloud-native app development. In this article, we’ll look at labs in the “Emerging Technology” track.
