Hunt exploitable vulnerabilities in your own app (Sponsor)
Don't have Mythos access?
Chainguard Harness builds your app from source in an isolated environment, then lets Mythos 5.1 hunt through a live instance for exploitable vulnerabilities. Each finding is reproducible and delivered with a recommended fix.
> Catch risks early: Find and patch exploitable vulnerabilities in your custom code and OSS before attackers do.
> Refocus engineering: Reproducible findings focus team attention and resources on the most actionable issues that are based specifically on your code.
> Avoid a massive bill: Skip building a custom test harness and burning cash on unoptimized tokens.

1M Durable Workflows per Second on Postgres (6 minute read)
DBOS scaled a benchmark of no-op durable workflows from 20,000 per second on one Postgres server to one million across 50 shards using PgDog. The main obstacle was a contention feedback loop that collapsed throughput when a shard slowed down. Advisory locks limited concurrent dequeuers and restored stable scaling.
One Hub, 34 Clusters: Lessons From a GitOps Control Plane at Scale (5 minute read)
Nitish Mane describes an Argo CD hub that managed 34 clusters across 22 AWS accounts and one Oracle Cloud tenancy from a repository of 174 Helm charts. Per-cluster contracts, CI manifest diffs, and no-prune settings kept changes safe, and onboarding reportedly fell from 4 days to 1.7 hours.
How to Integrate Terraform with Backstage for Self-Service (17 minute read)
Mattias FjellstrΓΆm explains how to connect Terraform with Backstage through the software catalog, software templates that open pull requests, and the Spacelift plugin. Backstage collects requests but does not run Terraform, so version control remains the source of truth.

Macro (GitHub Repo)
Macro is a unified workspace that combines email, chat, docs, tasks, agents, and CRM into a single interface with shared team memory. It links all objects, such as emails and tasks, via a bidirectional graph so AI agents and users can search across tools without switching contexts.
The Pwn Request Reckoning: What Still Works Against GitHub Actions (9 minute read)
GitHub's upcoming platform changes in 2026 will make pull_request_target attacks harder, but gaps remain involving outdated checkout versions, script injection, and unprotected triggers like issue_comment. Pinning actions to old SHA values predating the July 2026 backport release bypasses the new checkout protections entirely. The default policy also does not apply to private repositories or workflow_run events.
The AI observability race will be won on interoperability (5 minute read)
OpenTelemetry offers a common method to capture and describe AI behavior using shared conventions for conversations and messages. This standardization helps teams compare models, reduce duplicate integration work, and measure cost per outcome rather than just token counts.
