<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Cloudflare has introduced cf, a new command-line interface that allows agents to access over 3,000 operations across the entire Cloudflare API. Wrangler previously supported around 280 commands, and agent usage of that tool reached 48% last week. cf uses a unified API generation pipeline to standardize commands and defaults to JSON output for agents. Cloudflare will provide maintenance support for Wrangler for 18 months after the beta ends.

<strong>Beyond Kubernetes at Modal: How to Scale 1 Million Concurrent Sandboxes in Seconds (5 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Modal engineers rebuilt their sandbox platform to support millions of concurrent sandboxes by replacing Kubernetes-style centralized coordination with distributed worker state and parallel scheduling. The redesign created one million sandboxes in under 60 seconds with sub-half-second startup times, prompting talk that infrastructure is splitting into separate coordination and execution planes.

<strong>How Uber Protects Against Retry Storms (12 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Uber added error ownership to its shared service-mesh infrastructure, so upstream services can distinguish failures they caused from errors merely propagated from deeper dependencies. During a major outage, the mechanism prevented an estimated 9.5 million unnecessary retry requests and reduced the maximum retry-storm radius across user-facing APIs from as high as 25 hops to 3.

<strong>BigQuery to ClickHouse at 15M Call Minutes a Day: What Broke, What We Fixed, and How We Cut Costs 6x (8 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Bolna migrated analytics from BigQuery to ClickHouse, moved expensive CDC deduplication into materialized views, and fixed missing TOASTed JSONB values with REPLICA IDENTITY FULL. Reducing intermediate application writes cut replication traffic, with Bolna reporting roughly 6× lower analytics costs and data availability improving from 5–15 minutes to 1–2 minutes after calls ended.

OpenShell is an Apache-2.0 runtime for running autonomous agents inside isolated sandboxes with kernel-enforced filesystem, syscall, and network policies. Credentials are injected only for approved endpoints, while proposed policy changes are formally checked before they are applied. The platform also supports Kubernetes deployment, GPUs, and Python, TypeScript, Go, and Rust SDKs.

<strong>What Dependency Mocking Software Needs to Handle in a Cloud Native Architecture (4 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Traditional dependency mocking tools break down in cloud native architectures where services deploy independently and drift goes undetected. Effective tools need deployment event awareness, behavior captured from real traffic rather than specs, automatic handling of non-deterministic fields, and cross-service diff visibility, with eBPF-based traffic capture cited as one approach.

<strong>Can your Postgres survive a bad query? (16 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Postgres memory limits such as work_mem apply per execution node and per worker rather than per query, allowing seemingly ordinary queries to consume many times the configured amount of memory. Recursive queries can be even more dangerous because some executor hash tables cannot spill to disk, creating workloads that can exhaust memory despite conservative configuration.
