🔹 Kubernetes - Kubernetes v1.34: Recovery From Volume Expansion Failure (GA)

The blog post discusses the new feature in Kubernetes v1.34 that allows automated recovery from volume expansion failures and has reached general availability. Previously, correcting mistakes like typos in persistent volume expansion required manual intervention and cluster-admin access, but now users can reduce the requested size of a PersistentVolumeClaim (PVC) if the expansion hasn’t completed. This enables Kubernetes to automatically correct the size and return any consumed quota. The update also includes improved error handling and observability for volume expansions, introducing new API fields to monitor progress and error conditions. This feature addresses longstanding bugs and enhances the overall resizing workflow. The blog acknowledges contributors who helped achieve this improvement. 👉 Read more

🔹 Java - Paths to Support Additional Numeric Types on the Java Platform #JVMLS

The tech blog post titled “Paths to Support Additional Numeric Types on the Java Platform” discusses the potential for expanding the range of numeric types available in the Java platform. While Java’s current set of numeric types has remained stable over the years, there is a growing demand for additional types, particularly for scientific, engineering, and machine learning applications. These fields can benefit from using linear algebra, complex numbers, and smaller numeric types like 16-bit and even 8-bit floating-point numbers, which are being considered by the IEEE SA Working Group P3109 for standardization. The talk addresses what is necessary to fully support these new numeric types in Java and explores the trade-offs involved in different approaches to implementing this support. 👉 Read more
