Developing NVIDIA Holoscan Applications with CLI, Skills, and AI Coding Agents
NVIDIA Holoscan is a platform for building real-time AI applications at the edge, from medical imaging to robotics. HoloHub is its companion repository: a...
Building Federated Multimodal AI Workflows with NVIDIA FLARE
Modern vision-language models (VLMs) can support tasks such as visual question answering, captioning, and image-text reasoning. In practice, however, the data...
A revisit of remote Spectre attacks on Cloudflare Workers
In 2024 and 2025, we reassessed remote Spectre attacks on our Workers infrastructure. We share details about the new attack primitives like Spectre gadgets, remote timers, achieving co-location and how new defenses further harden Cloudflare Workers.
Post-Train NVIDIA Cosmos 3 Edge for On-Device Robot Control
Robots need policies that can adapt to their sensors, environments, and tasks while running on onboard computing hardware. World models offer a foundation for...
Evaluating AI Agent Skill Performance with NVIDIA SkillEvaluator
AI agents are only as effective as the context they receive. Even with capable models and well-documented NVIDIA libraries, agents can spend extra steps finding...
How CISA’s BOD 26-04 changes vulnerability prioritization
Learn how CISA’s BOD 26-04 mandates risk-based vulnerability prioritization and how Datadog helps teams prioritize and remediate critical findings.
20× the CI traffic without getting slower: How we rebuilt Git serving at Datadog
Learn how Datadog built gitretriever to handle 20× more CI Git traffic while maintaining low latency and reducing backend CPU usage.
How AI Coding Agents Can Unlock Materials Simulation with NVIDIA ALCHEMI Toolkit
Atomistic simulation requires three things: knowledge of the science, compute-efficient implementation of simulations, and accessible interfaces to the...
Run Massive-Scale UMAP in Minutes Using Multiple GPUs—Without Losing Accuracy
Uniform Manifold Approximation and Projection (UMAP) is a dimensionality reduction technique widely used for visualization and feature extraction. Applications...
BGP Role model: tracking the adoption of RFC 9234
RFC 9234 lets routers reject route leaks on their own, using BGP Roles and the Only to Customer attribute. We measured who has deployed it, and found two Tier 1 networks unexpectedly stripping OTC.
Two ways to measure the cumulative impact of experiments
Summing individual wins overstates true impact. See two accurate methods, holdouts and Datadog’s Cumulative Impact, and how to choose between them.
Centralize human and agentic work with Datadog Work Management

A letter to the Discord community in Brazil
On the order from Brazil's ANPD to suspend screensharing and video features in the country, how we're complying, and our commitment to our community in Brazil.
How Cloudflare detects MCP traffic and helps secure it
Cloudflare Gateway identifies MCP requests using protocol-level heuristics. Security teams can use that signal to find shadow MCP traffic, enforce Portal-only access for approved servers, and block direct connections on managed network paths.
Secure all your internal vibe-coded applications — in one click
Introducing Cloudflare Access for Workers. Attach an Access policy directly to a Worker and it applies everywhere that Worker runs — routes, custom domains, workers.dev, and previews — automatically.
