Scaling LunaDb, our in-house declarative data loading system • Asana Scaling LunaDb, our in-house declarative data loading system — describes a large architecture we undertook to break apart our data loading monolith

Learn how Asana uses GraalVM to run Scala and TypeScript in the same process, sharing caches to accelerate data computation for live client updates: asana.com/resources/sc...

Interesting comparison from the @quarkus.io maintainers shows that @graalvm.org native image remains by far the best option to deploy Quarkus applications for optimizing startup time, container image size, and memory consumption (RSS). Link in comments.

PyEditor for ESA SNAP, available since v1.5 of EOMasters Toolbox Pro, allows to use packages like #numpy on Linux and do data analysis directly in SNAP.
On Windows this will still take a little while. The maintainers of GraalPython are working on this. @graalvm.org

This is one of the @tamboui.dev demo applications, compiled to a native binary using @graalvm.org . It runs natively at 60fps+ (only limited by the refresh rate that is set in the demo) and consumes about 20MB of RAM.
