SelfHeal Uses LLM Patches to Repair Failing Python Apps With Rollback Safety

·1 views

SelfHeal is a tool that responds when a Python function raises an error or fails a health check. It asks a large language model to generate a code patch for the problem. The patch is first checked for syntax and tested with pytest in a copied workspace. The running function is only updated after the user approves the change, and if activation fails, the system reverts to the previous version.

NVKE: Open Source Tool for Running Managed GPU Kubernetes Clusters on Your Own Hardware

NVIDIA Kubernetes Engine (NVKE) is an open source, Apache-2.0 licensed project that lets platform teams create and operate isolated Kubernetes clusters on bare-metal GPU servers they own. It runs as a management plane on the hardware and provisions machines through NVIDIA Infra Controller, with each workload cluster getting its own control plane, etcd and node pools. Users interact with their clusters using standard kubectl, without needing to know NVKE exists. The project is currently in preview, its APIs may change between releases, and it is not recommended for production workloads. It is aimed mainly at organizations building internal Kubernetes-as-a-service offerings on GPU infrastructure.
