CVE-2025-49844 - The Redis CVSS 10.0 vulnerability and how we responded

Report URI closed the door on Redis CVE-2025-49844 fast. They rolled out ACL-based command blocks and jumped to Redis8.2.2, now running on a freshRedis Sentinel-based HA setup. To prove the fix stuck, they ran command counter checks and layered in enforced blocking rules—then pushed it all out fleet.. read more

A fully functional Kubernetes cluster with 1 million active nodes.

Pushing Kubernetes to 1M nodes isn’t just hardware—it's architectural judo. Networking flips to exclusive IPv6.Less chatter, more breathing room. etcd hits a wall.Write throughput stalls at scale, so they swap it out. Entermem_etcd, a Rust-built replacement pushing over 1M buffered writes per second.. read more

Connect Codex to MCP Servers via MCP Toolkit

OpenAI Codex just leveled up. It now hooks into Docker’sModel Context Protocol (MCP) Toolkit, which means it can tap directly into 200+ infrastructure tools—likeNeo4j graph databases—as if they were built-in features. With MCP, Codex doesn’t just code. It runs containers, spins up data models, eats .. read more

Hardened Images: crafted by humans, protected by AI

Docker just wired anAI guardrailstraight into its Hardened Image (DHI) pipeline. It scans upstream diffs, catches regressions before they ship, and stops bad logic in its tracks. Case in point: it flagged a logic bug that slipped past the usual coding copilots. A real fix landed upstream. Win for cu.. read more

How to Allocate Kubernetes Resource Ownership

Resource ownership in Kubernetes isn’t just a nice-to-have anymore—it’s turning into table stakes. Teams are usingnamespaces, RBAC, labels, quotas, and admission controllersto draw clear lines around who owns what, how much they can use, and what rules they follow. Tools likeKyverno,LimitRanges, and.. read more

GPT-5.3-Codex is OpenAI’s advanced agentic coding model, designed to go beyond writing code and operate as a general-purpose collaborator on a computer. It builds on GPT-5.2-Codex by combining stronger coding performance with improved reasoning and professional knowledge, while running about 25% faster. The model is optimized for long-running tasks that involve research, tool use, and complex execution, and it performs at the top of industry benchmarks such as SWE-Bench Pro and Terminal-Bench.

Unlike earlier Codex models that focused primarily on code generation and review, GPT-5.3-Codex can reason, plan, and act across the full software lifecycle. It supports activities such as debugging, deploying, monitoring, writing product requirement documents, creating tests, and analyzing metrics. It can also autonomously build and iterate on complex applications and better interpret underspecified prompts, producing more complete and production-ready results by default.

A defining feature of GPT-5.3-Codex is its interactive, agentic workflow. Users can steer the model while it is working, receive progress updates, and adjust direction without losing context, making it feel more like a teammate than a batch automation tool. The model was even used internally to help debug its own training and deployment processes. GPT-5.3-Codex is available through paid ChatGPT plans in the Codex app, CLI, IDE extension, and web, with API access planned for the future.
