November brought a full plate of new features written by developers working at Red Hat, and we are here to share the harvest. Keep reading for some of our reader's top picks and a few we really like, including updates for Red Hat Enterprise Linux 8.5 and Red Hat Enterprise Linux 9 Beta and developer guides to choosing your best Java garbage collector, building machine learning models in the cloud, bringing Kubernetes workloads to the edge, and so much more.
Note: See the end of this article for the full lineup published in November 2021.
How to get RHEL 8.5 and RHEL 9 Beta
The best news for many developers this month was the arrival of Red Hat Enterprise Linux 8.5 and Red Hat Enterprise Linux 9 Beta. Find out what's new in RHEL 8.5—including support for OpenJDK 17 and .NET 6—then look ahead to new features in RHEL 9 Beta. Both versions are available as a no-cost RHEL for developers subscription.
See these related articles for more about what you can do with RHEL 8.5:
Machine learning and data science in the cloud
As of this month, our collection of resources for building intelligent applications includes new ways to try out Red Hat OpenShift Data Science. Get an overview of this cloud-based AI/ML platform with Audrey Reznik's Building machine learning models in the cloud, then watch these video demonstrations from the OpenShift Data Science team:
- Access more data from your Jupyter notebook
- Build and deploy an object detection model using OpenShift Data Science
Note: If you like machine learning, you might also enjoy this inside look at Project Thoth's cloud-based dependency resolver, which uses reinforcement learning and custom criteria to resolve Python library dependencies.
Java tools and performance
It's been a great month for diving into Java performance and tools for profiling and monitoring in the JVM. If you're new to these topics, we recommend starting with Aashish Patil's How to choose the best Java garbage collector. Then, see:
- Runtime profiling in OpenJDK's HotSpot JVM
- JVM performance monitoring with JMC agent
- A faster way to access JDK Flight Recorder data
Developer Sandbox for Red Hat OpenShift
As a developer, you want to learn, but maybe your shop isn't working with state-of-the-art technologies. No problem! You can get hands-on experience with Kubernetes, microservices, machine learning, and more with the Developer Sandbox for Red Hat OpenShift, free with a Red Hat account. Get started with your Developer Sandbox today, then check out the growing menu of activities that you can try.
Debugging, authentication, microservices, and more
