GitHub releases gh-stack CLI extension for managing stacked pull requests

GitHub has introduced a CLI extension that automates the workflow for stacked branches and pull requests. The tool handles branch creation, rebasing, and setting correct base branches to break large changes into reviewable chains. It also includes an AI agent skill to help coding assistants understand the stacked PR context.

  • Automates tedious branch management and rebasing for stacked PR workflows
  • Requires GitHub CLI v2.0+ and installed via gh extension install
  • Includes an AI skill to enable coding agents to navigate stacked branches
  • Simplifies chaining small, reviewable PRs that build on each other

AWS DataSync Enhanced mode now supports EFS and FSx for Lustre

AWS DataSync Enhanced mode has expanded support to include Amazon EFS and Amazon FSx for Lustre as source or destination locations. This update allows users to leverage parallel processing, removal of file count limits, and detailed transfer metrics for these file systems. Previously restricted to Basic mode, these integrations are now available across all AWS regions.

  • Enhanced mode is now available for EFS and FSx for Lustre locations.
  • Enables parallel processing and removes file count limitations for these workloads.
  • Simplifies large-scale migrations and AI/ML training data movement.
  • Provides detailed transfer metrics for better observability.
  • Available in all AWS regions where DataSync is supported.

HashiCorp founder Marcin Dela launches faster terminal multiplexer with persistent sessions

HashiCorp co-founder Marcin Dela has released a new terminal multiplexer designed for higher performance than existing tools. The initial release highlights persistent sessions as a core feature, suggesting future capabilities may expand on this foundation. This entry marks Dela's return to the terminal multiplexing space with a focus on speed and reliability.

  • Marcin Dela, HashiCorp co-founder, is back with a new terminal tool.
  • The multiplexer prioritizes speed as its primary differentiator.
  • Persistent sessions are the headline feature in this initial release.
  • Expect further feature expansion beyond session persistence.

Terraform introduces tfpolicy, an HCL-based policy-as-code framework

HashiCorp has launched tfpolicy in public beta for HCP Terraform, offering a policy-as-code framework built directly on HCL. This tool integrates governance creation and enforcement into standard Terraform workflows, removing the dependency on external policy engines or separate languages. The move aims to modernize infrastructure governance by simplifying the operational overhead associated with policy management.

  • tfpolicy enables HCL-native policy-as-code, eliminating the need for external tools or Rego.
  • Governance creation and enforcement are now embedded directly within Terraform workflows.
  • Public beta availability starts within HCP Terraform for early adopters.
  • Aims to reduce complexity by unifying infrastructure definition and policy logic.

AWS CloudWatch introduces managed Prometheus collectors for zero-agent monitoring

Amazon CloudWatch now offers fully managed Prometheus collectors to ingest metrics from EKS, EC2, ECS, MSK, and OpenSearch without requiring self-managed agents. This replaces the previous need to deploy and scale OpenTelemetry Collectors, as CloudWatch now handles provisioning and scraping automatically via user-provided configurations. Metrics arrive in OpenTelemetry format and are queryable with PromQL alongside native AWS metrics.

  • Eliminates the operational overhead of deploying and scaling self-managed OpenTelemetry Collectors.
  • Supports zero-agent metric collection from key AWS services including EKS, EC2, and MSK.
  • Enables unified PromQL querying across vended AWS metrics and collected Prometheus data.

Idle GPUs: The New Grounded Aircraft in AI Infrastructure

Hugging Face highlights how unutilized GPU capacity represents a critical inefficiency in modern AI operations, likening it to grounded aircraft. The blog post argues that managing compute resources requires proactive scheduling and allocation strategies to maximize utilization rates. This shift emphasizes the need for robust orchestration tools to prevent hardware idleness during peak demand periods.

  • Idle GPUs signal significant operational waste and missed inference/training opportunities.
  • Proactive resource orchestration is essential to maintain high hardware utilization.
  • Treating compute like grounded aircraft reframes the urgency of scheduling efficiency.
  • Infrastructure costs rise directly with increased periods of GPU idleness.

AWS Direct Connect adds BGP route visibility for VIFs

AWS Direct Connect now exposes BGP route details for private, transit, and public virtual interfaces. Users can inspect accepted and advertised routes, including AS paths and community values, via the console or the ListVirtualInterfaceRoutes API. This capability aids in troubleshooting routing issues and verifying hybrid network propagation.

  • Inspect BGP communities and AS paths for all VIF types directly in the console.
  • Use ListVirtualInterfaceRoutes API for programmatic route auditing and automation.
  • Verify route propagation between on-premises routers and AWS edge nodes.
  • Troubleshoot hybrid connectivity issues by comparing accepted vs. advertised routes.

IAM Policy Simulator moves to console with SCP testing

AWS has integrated the IAM Policy Simulator directly into the IAM console, replacing the standalone tool to centralize identity and policy management. The update enables testing of Service Control Policies (SCPs), allowing teams to validate how organizational constraints interact with identity and resource policies. This consolidation supports more realistic scenario modeling for security and platform engineers.

  • Simulator is now native to the IAM console, removing the standalone URL.
  • New capability to test SCPs alongside identity and resource policies.
  • Centralized location simplifies validation workflows for platform teams.
  • API support retained for automation and condition key testing.
