Uber engineered native gRPC endpoints directly into OpenSearch to eliminate inefficient REST/JSON translation layers within their architecture. Their automated pipeline for syncing JSON APIs with Protobuf schemas, their internal integration strategy, and the resulting performance gains in production environments for high-throughput ingestion and vector search workloads.
- Uber implemented gRPC as an OpenSearch module
- To prevent divergence between REST and gRPC, Uber built a three-stage automated pipeline
- Removing the JSON-to-Protobuf translation layer reduced p99 index write latency by 60% for Uber’s M3 metrics system and decreased batch indexing job runtimes by 20-35%.
- Large vector searches, which serialize poorly in JSON, saw a 53% reduction in p50 latency and a 43% reduction in p95 latency.
- Combining gRPC with binary document formats like SMILE proved highly effective, executing 30% faster than REST JSON and 45% faster than gRPC JSON.

The proliferation of AI coding models has drastically lowered the barrier to discovering software vulnerabilities, resulting in a massive influx of automated, low-quality, and false-positive vulnerability reports. This volume is overwhelming open-source maintainers and security teams. The article outlines how the industry must adapt, offering specific strategies for companies, maintainers, and external bug hunters to manage triage, improve report quality, and prevent ecosystem burnout.

Microsoft is so jealous of Claude Code's success that they decided to include a "co-author" credit for GitHub Copilot, even if Copilot has done nothing.

Red Hat critiques a recent VMware study that claimed VMware Cloud Foundation (VCF) with vSphere Kubernetes Service (VKS) offers a "5.6x pod density" advantage over Red Hat OpenShift. The benchmark as an architectural mismatch rather than an accurate performance evaluation, noting that VMware compared 300 overcommitted virtual worker nodes against 4 bare-metal OpenShift nodes.

The article addresses the "broken" scale of AI model distribution, where transferring massive models (like a 130GB DeepSeek-V3) to hundreds of GPU nodes simultaneously bottlenecks network bandwidth and hits rate limits on hubs like Hugging Face. The solution is the CNCF project Dragonfly, which uses a Peer-to-Peer (P2P) architecture to ensure a model is fetched from the origin only once. It details new native protocol support for hf:// and modelscope://, allowing dfget (Dragonfly's download tool) to natively understand these hubs, reducing origin traffic by up to 99.5% and enabling wire-speed distribution across clusters.

Following the announced retirement of the ingress-nginx project, the CNCF migrated its internal services cluster to Envoy Gateway (an implementation of the Gateway API). Rather than a generic tutorial, the post details their specific architectural decisions, such as utilizing a shared Gateway object across multiple HTTPRoutes to optimize cloud load balancer costs and operational simplicity. It also covers the migration strategies they used for maintaining the same IP address, handling legacy certificates, and conducting "Day 2" operations with cert-manager.

The article introduces GKE Active Buffer, a native feature designed to solve the persistent problem of scale-out latency in Kubernetes. Traditionally, cluster autoscaling suffers from delays while provisioning new VMs and pulling container images. To solve this, admins often used "balloon pods" (dummy pods that hold space), which are "hacky," complex to manage, and lack native integration. GKE Active Buffer replaces these with a declarative CapacityBuffer API, providing a standardized, portable way to maintain "warm" capacity. This allows business-critical workloads—such as AI inference, retail flash sales, and gaming—to land on pre-provisioned capacity nearly instantaneously.

In the modern world of services, the teams developing and working with them need to understand the concept of rate limiting. Being able to design these systems is crucial to avoid service denial and provide higher uptime. It is an important part not only for externally available services, but also for internal ones.

Tech giants under attack by a Trivy-compromised GitHub action.
Cisco – More than 300 GitHub repositories were cloned during the incident, including source code for its AI-powered products, such as AI Assistants, AI Defense, and unreleased products. A portion of the stolen repositories allegedly belongs to corporate customers, including banks, BPOs, and US government agencies.
