DIGITALOCEAN MICROVMS: FAST, ISOLATED COMPUTE FOR YOUR AI AGENT INFRASTRUCTURE

DigitalOcean has released MicroVMs in public preview, offering isolated virtual machines that pause when idle and resume in milliseconds. The service costs $0.022 per vCPU-hour and $0.0085 per GiB-hour for compute, billed per second, while paused instances only incur storage fees. MicroVMs are built on the open-source Firecracker platform and are designed for workloads like coding agents, sandboxes, and CI/CD runners.

ZERO-DOWNTIME POSTGRESQL MIGRATIONS: A PRODUCTION PLAYBOOK FOR SAFE SCHEMA CHANGES

Safe PostgreSQL schema changes separate expansion, backfills, traffic switches, and cleanup so old and new application versions remain compatible during deployment. Short lock timeouts, concurrent index builds, separately validated constraints, and throttled backfills limit disruption, while monitoring replica lag and data consistency determines when each phase can proceed.

AGENTIC EVALUATIONS: BENCHMARK AI AGENT QUALITY, PERFORMANCE, & SAFETY

Anthropic has introduced a new concept called agentic evaluations, or agentevals, to verify that AI agents perform tasks correctly and safely. The tool grades agent traces based on specific criteria like performance, output quality, and safety. Developers can install agentevals via a Python package or clone the source repository from GitHub.

WHAT TODAY'S SOFTWARE OWES TO BRONZE AGE CLOCKS

Leaky buckets provide inexpensive admission control by calculating available capacity from elapsed time rather than running a background timer. PlanetScale applies related token-bucket budgets to Postgres queries, estimating resource costs before execution and reconciling actual costs afterward to control bursts and protect database capacity.

INTRODUCING ON-DEMAND CPU AND MEMORY PROFILING WITH FLAMEGRAPHS FOR WORKERS AND DURABLE OBJECTS

Cloudflare added on-demand production CPU and memory profiling for Workers and Durable Objects, with interactive flamegraphs and downloadable profiles. Internal profiling uncovered redundant JSON processing and partially disabled metrics code that still consumed memory. Memory profiles capture allocations during the recording window rather than the entire existing heap.
