Package errors provides simple error handling primitives. The traditional error handling idiom in Go that is applied recursively up the call stack results in error reports without context or debugging information. The errors package allows programmers to add context to the failure path in their code in a way that does not destroy the original value of the error. Wrap function returns a new error that adds context to the original error. Using errors.Wrap constructs a stack of errors, adding context to the preceding error. ...

netstack is a userspace TCP/IP networking stack written in Go that implements core IPv4/IPv6 protocols with a focus on correctness, isolation, and testability. By running entirely in user space, it avoids kernel dependencies and can be embedded into sandboxes, virtualized environments, or custom appliances. Its architecture models NICs, link endpoints, route tables, and protocol engines as composable interfaces, enabling precise control over packet flow and easy mocking in tests. ...

Origin, also known as OKD is the community distribution of Kubernetes that has been optimized for continuous application development and multi-tenant deployment. It adds developer and operations-centred tools to Kubernetes to speed up application development and simplify deployment, scaling, as well as long-term lifecycle maintenance. It also makes it easier to launch Kubernetes on any cloud or bare metal and run and update clusters, while providing all the necessary tools for creating...

Hawaii is a desktop operating system built on the GNU/Linux stack with a new lightweight and fast Wayland desktop environment written with QtQuick and deeply integrated with systemd. Hawaii delivers incremental and atomic updates which gives users to ability to rollback the whole system to a known good state if a regression happens.

...On BSD-derived systems such as OSX, we use tools like ipfw and pfctl to inject failure. On Linux, we use iptables and tc. Comcast is merely a thin wrapper around these controls. Windows support may be possible with wipfw or even the native network stack, but this has not yet been implemented in Comcast and may be at a later date. On Linux, Comcast supports several options: device, latency, target/default bandwidth, packet loss, protocol, and port number.

novm is an experimental, minimalist virtual machine monitor that explores running Linux guests with a streamlined user-space control plane. Its goal is fast, scriptable VM lifecycle management—boot, snapshot, pause, resume—without the heft of a full cloud stack. The design favors small, understandable code paths around KVM and tap networking so developers can reason about isolation and performance trade-offs. It showcases patterns like process-per-VM supervision, concise configuration, and direct mapping of devices needed for common development workloads. As a research vehicle, novm emphasizes hackability over feature completeness, making it useful for instrumentation experiments, educational deep dives, or bespoke CI sandboxes. ...
