Topic

Taking off With JDK Flight Recorder

Are you running into problems with Java applications in production? Not understanding what is eating up all your system resources? And throwing a bunch of System.out messages in your code is not helping? You should check out the JDK Flight Recorder (JFR). JFR is a powerful and low-overhead observability tool built into the JVM that can help you track down those performance issues and difficult-to-understand bugs. In this presentation, we will go through the basics of using JFR in your Java applications.

Thu, Sep 26, 2024, 6:30 PM EDTSolving Gradle Build Challenges with Gradle Plugins - Ihor Herasymenko
Free Times Cafe, Toronto, ON
Solving Gradle Build Challenges with Gradle Plugins

Writing custom build logic in Gradle can be as easy as adding a few lines of imperative
Groovy code to your build scripts; however, this approach does not scale well. As projects
grow, this often results in fragile builds that everyone hates and nobody can understand.
In this talk, we are going to see how we can better structure our builds with the help of
Gradle Plugins.

We will explore different kinds of Gradle Plugins, when and where to use them, and develop
an integration for a JDK tool that Gradle does not support out-of-the-box.

We will dive into Gradle’s core extension points, such as Tasks, Extensions, Properties,
Providers, Artifact Transforms, and see how to wire them all together in order to create a
piece of custom, reusable, and well-tested build logic.

Thu, Oct 31, 2024, 6:30 PM EDTWebAssembly and Java - Ming Iu
Free Times Cafe, Toronto, ON
WebAssembly and Java

WebAssembly is the exciting technology that allows you to program for the web in languages other than JavaScript. There's been a lot of hype surrounding it, with some speculating that it could not only replace JavaScript, but it could replace Java virtual machines as well. Some people are even trying to use WebAssembly for cloud computing and have suggested that it could actually replace Docker.

Come on an overview tour of WebAssembly and the WebAssembly ecosystem where we try to discover how much of this hype is justified.

The talk will look at how WebAssembly differentiates itself from Java bytecode, despite the conceptual similarities between the two. We'll try to understand the WebAssembly security sandbox and compare it to other ways of sandboxing your code. We'll examine the rationale for running WebAssembly on the server, and briefly touch on how to run WebAssembly code from inside your Java programs. Finally, the talk will discuss why Java programmers aren't using WebAssembly despite the fact that browsers have supported it since 2017, and it will discuss why that might change in the future.
