About

Agent Substrate is an open-source runtime for operating isolated, stateful agent and code-execution sandboxes on Kubernetes. It coordinates actor and worker lifecycles, places active workloads on a shared pool of ready capacity, and can suspend idle environments while preserving memory and filesystem state for later resumption. Sandboxes use gVisor or Cloud Hypervisor microVM isolation, with per-actor identity and network controls. Agent Substrate is designed for platform and infrastructure teams building agent-hosting services, coding environments, and other workloads that execute untrusted or intermittent tasks. The core project is Kubernetes-portable; Google Cloud also provides GKE-optimized deployment tooling. Optional Filestore agent volumes can persist workspaces across suspend and resume cycles.

About

RAMKeeper is a macOS menu bar utility for people who want to understand and manage memory use on a Mac. Its free direct-download build attributes memory to apps and browser or Electron renderer processes, grouping helpers under parent apps and showing current and peak readings. A separate free Mac App Store build reports system-level memory pressure, swap and compressed memory; Apple's sandbox prevents it from showing per-app memory. The $19 one-time Pro unlock for the direct build adds configurable memory-threshold rules that can notify, gently restart or suspend an app, Focus Mode to suspend and resume background apps, and a history of actions with before-and-after readings. Controls are off until configured. The app runs on macOS 12 or later on Apple silicon and Intel Macs, and memory analysis occurs locally.
