Burstable VMs run on a fraction of CPU and burst to a higher level of CPU usage to support occasional usage spikes. To implement them, we leveraged Control Groups v2 (cgroups v2), a Linux kernel feature that helps manage resource usage. We thought our open-source implementation of burstable VMs might be interesting…
What Observability 2.0 means in practice, how wide events replace siloed metrics/logs/traces, and why GreptimeDB is purpose-built as the database foundation.
We benchmarked OpenTelemetry overhead in a high-load Go app against eBPF-based instrumentation to see where tracing adds real cost.
In this post, we’re highlighting 4via6 subnet routing — a powerful way to extend Tailscale’s mesh across entire edge or customer networks. It’s ideal for scenarios where traditional VPNs struggle, like fleets of robots, sensors, or isolated cloud environments.
Introducing llm-d: Kubernetes-native distributed LLM inference with KV-cache routing, disaggregated serving, and SOTA performance per dollar. Built on vLLM.
A practical, no-fluff guide to understanding the OpenTelemetry Collector - what it does, how it works, real architecture patterns (with and without it).
Discover how Nix can revolutionize your software supply chain security, enabling verifiable integrity and offline rebuilds from source.
I'm done talking about microservices: the term is confusing, discussions are abstract, and without organisational change, microservices are pointless
Understand OpenTelemetry traces and spans with real code examples. Instrument Node.js/TypeScript apps for distributed tracing and faster debugging.
This blog post covers how we virtualized NVIDIA HGX B200 GPUs using open-source software. It talks about VFIO passthrough, QEMU PCI topology fixes, large BAR boot stalls, and Fabric Manager partitions.
In this blog, we share a new finding in the XZ Utils saga: several Docker images built around the time of the compromise contain the backdoor. At first…
Our experience running AWS EBS at scale for critical workloads
A misconfiguration that might have cost us $7,000
Run reproducible, immutable environments in Kubernetes without container images. Faster deploys, SBOMs-by-default, and zero drift with Flox.
Editor’s note (August 25, 2026): Updated the Node20 removal date to September 23rd, 2026. Editor’s note (February 25, 2026): Updated the migration date to June of 2026. Editor’s note (May…
To provide a secure and dependable experience on GitHub, we’re rolling out updates to rate limits for requests made without authentication. These changes will apply to operations like cloning repositories…
We are excited to announce the next phase of the OpenTelemetry Protocol with Apache Arrow project (OTel-Arrow). We began this project several years ago with the goal of bridging between OpenTelemetry data and the Apache Arrow ecosystem. Apache Arrow is a framework designed for zero-copy exchange of structured data…
When your CI pipelines are slow, you can only optimize so much. Bottlenecks in CPU, Network, Memory, and Disk I/O can all contribute to slow CI pipelines. Let's take a look at how disk I/O can be a bottleneck in GitHub Actions.
Read how Google is using System Theoretic Process Analysis (STPA) to analyze pure software systems and discover risks.
We’re launching Stargate Norway—OpenAI’s first AI data center initiative in Europe under our OpenAI for Countries program. Stargate is OpenAI’s overarching infrastructure platform and is a critical part of our long-term vision to deliver the benefits of AI to everyone.
At Uber, our MySQL® fleet is the backbone of our data infrastructure, supporting a vast array of operations critical to our platform. Uber operates an extensive MySQL fleet, consisting of over 2,300 independent clusters. Building a control plane to manage this fleet at such a massive scale, while ensuring zero…
Fluid Storage reimagines block storage like EBS with zero-copy forks, true elasticity, and sync replication. Built for the age of agents.
Apache Iceberg and Parquet now support native geospatial types, connecting Wherobots, PostGIS, Sedona, Databricks, and Snowflake to one table format.
We analyzed if AWS’ N. Virginia region remains the least reliable in 2025. Overview of outages, affected services, and the massive October 20 AWS incident, with insights from StatusGator’s real-time monitoring.
rules_img is a Bazel ruleset for building and publishing OCI images that feel native to Bazel by treating images as metadata first and moving bytes only at the edges.
Docker Model Runner is a faster, simpler way to run and test AI models locally, right from your existing workflow.
