    Napkin Math

    Napkin Math

    Techniques and numbers for estimating system's performance

    Napkin Math is a technical reference project for estimating software system performance from first principles.

    Mac Development Ansible Playbook

    Mac Development Ansible Playbook

    Mac setup and configuration via Ansible

    ...It handles everything from installing Homebrew and CLI tools to configuring dotfiles, apps, system preferences, and macOS behavior. The goal is to make provisioning a new Mac (or re-provisioning an existing one) fast, reliable, and repeatable. The playbook integrates roles for common functionality, uses tagged tasks to allow fine-grained selection (e.g., only dotfiles or only Homebrew apps), and provides default configurations that can easily be overridden via a config.yml. Because many steps in macOS setup are manual or brittle (especially GUI apps, App Store installs, system preferences), this playbook bridges the gap between a “clean install” and a fully configured dev machine. ...

    ChartGPU

    ChartGPU

    Beautiful, open source, WebGPU-based charting library

    The ChartGPU repository is an open-source, WebGPU-based charting library written in TypeScript that enables developers to visualize large datasets with high performance and smooth interactivity even when handling millions of data points. By leveraging WebGPU — the next-generation graphics API for the web — ChartGPU offloads rendering work to the GPU, allowing for fast panning, zooming, and real-time updates with minimal latency. This makes the library particularly valuable for data-intensive dashboards, scientific visualizations, and financial charting where performance bottlenecks of traditional canvas or SVG approaches become apparent. It includes support for common chart types like line, bar, scatter, and candlestick plots, and its architecture is designed to scale with both visual complexity and data volume.
