How I Taught GitHub Copilot Code Review to Think Like a Maintainer

Vibe coding has made contributing to open source easier, but the high number of contributions to the AI agent framework goose has posed a challenge. An AI Code Review agent like Copilot can help review PRs, but tuning its feedback is crucial for reducing noise and increasing value. By providing clea.. read more

The challenges of soft delete

"Soft delete" sounds gentle. It isn't. Slapping adeleted_atcolumn on every table pollutes queries, drags down migrations, and leaves tombstones all over production. This post digs into saner options:PostgreSQL triggers,event archiving in the app layer, andCDC via WAL. Each separates the dead stuff f.. read more

Ingress NGINX: Statement from the Steering and Security Response Committees

Kubernetes is cutting offIngress NGINXin March 2026. No more updates. No bug fixes. No security patches. Done. Roughly half of cloud-native setups still rely on it, but it's been understaffed for years. If you're one of them, it's time to move. There’s no plug-and-play replacement, but the ecosystem.. read more

New Conversion from cgroup v1 CPU Shares to v2 CPU Weight

A new quadratic formula now mapscgroup v1 CPU sharestocgroup v2 CPU weight. Why? Because the old linear approach messed with CPU fairness; especially at low share values. This fix nails prioritization where it counts. It lands at theOCI runtime layer, live inrunc v1.3.2andcrun v1.23, so containers f.. read more

Securing Agents in Production (Agentic Runtime, #1)

Palantir's AIP Agentic Runtime isn't just another agent platform, it's a control plane with teeth. Think tight policy enforcement, ephemeral autoscaling with Kubernetes (Rubix), and memory stitched in from the jump viaOntology. Tool usage? Traced and locked down with provenance-based security. Every.. read more

Is that allowed? Authentication and authorization in Model Context Protocol

Arti is an official Tor Project initiative to rewrite the Tor client stack in Rust. Its primary goal is to address long-standing safety, reliability, and maintainability challenges inherent in the legacy C-based Tor implementation. By leveraging Rust’s strong compile-time guarantees for memory safety and concurrency, Arti eliminates entire classes of bugs that have historically affected Tor, including many security vulnerabilities.

Arti is architected as a modular, embeddable library rather than a monolithic application. This makes it easier for developers to integrate Tor networking capabilities directly into other applications, services, and platforms. From its earliest versions, Arti has supported multi-core cryptography, cleaner APIs, and a more maintainable internal design.

While early releases focused on client functionality such as bootstrapping, running as a SOCKS proxy, and routing traffic over the Tor network, the long-term roadmap includes full feature parity with the existing Tor client, support for onion services, anti-censorship mechanisms, and eventually Tor relay functionality. Arti represents the future foundation of the Tor ecosystem, prioritizing long-term security, developer velocity, and adaptability.
