Amazon EC2 has introduced the ability to create nested environments within virtualized instances, a capability previously limited to bare metal EC2. Available on C8i, M8i, and R8i instances across all commercial regions, this allows customers to run KVM or Hyper-V for use cases such as mobile application emulators and Windows Subsystem for Linux.

Go 1.26 introduces a completely rewritten `go fix` subcommand that automatically modernizes Go code by applying fixes that leverage newer language features, such as the enhanced `new` function, to improve clarity and ensure LLMs are trained on current idioms. This advancement builds upon the Go analysis framework and foreshadows a future "self-service" paradigm for user-defined modernizations.

The new `terraform-state` provider for Pulumi ESC is designed to directly read outputs from Terraform state files and integrate them as first-class values within ESC environments. This eliminates manual copy-pasting and scripts, automatically treating sensitive Terraform outputs as secrets and supporting remote backends like Terraform Cloud.

AWS built an open source Kubernetes controller to integrate Karpenter with Amazon Application Recovery Controller zonal shift, automatically reconfiguring node pools to avoid impaired Availability Zones during failures. The solution improves EKS resiliency, aligns autoscaling with traffic shifts, and can be tested using AWS Fault Injection Service.

<strong>Bias Toward Action (9 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Bias toward action means taking the smallest responsible step that generates real user feedback—while building guardrails (feature flags, monitoring, rollbacks, and error budgets) that make being wrong safe and quickly reversible. Fast teams aren't reckless - they invest in infrastructure that makes frequent, low-risk deployments boring, so they can learn quickly without compromising reliability.

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
roam pre-indexes your codebase into a semantic graph so AI agents can query structure instead of grepping files. Unlike LSPs (editor-bound and language-specific) or Sourcegraph (hosted search), roam provides architecture-level graph queries - offline, cross-language, and compact.

<strong>The only developer productivity metrics that matter (2 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Most software productivity metrics are meaningless because teams can game them. The only two metrics that actually matter are how routinely a team ships new versions and how rarely those releases cause serious production breakages. If a team ships at least weekly and production almost never goes down, then the next metric to optimize is whether each release genuinely makes users happier.
