Crabbox is a production-grade, multi-provider remote development environment orchestrator. The core is a Go CLI that provisions ephemeral sandboxes, VMs, and containers across 60+ cloud and virtualization backends (AWS, Azure, GCP, Hetzner, Firecracker, Docker, KubeVirt, Nomad, and many delegated-run services). Users issue commands like `crabbox run`, `warmup`, `connect`, `ssh`, `vnc`, and `cp`; the CLI leases a remote host, syncs a workspace archive, executes commands or opens interactive sessions, collects artifacts and test results, and tears the resource down. A Cloudflare Worker/Node.js coordinator handles lease state, provider reconciliation, artifacts, and runtime-adapter relays, while a Swift/Virtualization.framework daemon supports Apple VM backends. This is an application, not a research or data-analysis project, though it emits operational telemetry and parses remote JUnit results as part of its execution pipeline.
The thoughtbot dotfiles repository provides a comprehensive set of configuration files and scripts to set up a developer's environment, primarily targeting Zsh, Vim, Tmux, and Git. It uses the rcm tool to manage symlinking of dotfiles into the user's home directory, allowing for easy updates and local overrides. The repository includes shell aliases, functions, and key bindings for Zsh; Vim configuration with plugins for enhanced functionality (including fzf, vim-rails, and ALE linting); Tmux configuration for improved status bar and navigation; and Git configuration with useful aliases and hooks. Additionally, it provides a collection of helper scripts in the `bin/` directory for common tasks such as branch management, port clearing, and file replacement. The architecture is modular, with separate directories for Zsh, Vim, Git templates, and bin scripts. The Zsh configuration is split into configs, functions, and completions, which are loaded in a specific order. The Vim configuration uses vim-plug for plugin management and includes settings for syntax highlighting, linting, and navigation. The Tmux configuration improves color resolution, removes administrative debris from the status bar, sets the prefix to Ctrl+s, and softens the status bar color. The Git configuration adds aliases for creating, deleting, merging, and renaming branches, fetching and rebasing onto the default branch, and trusting project bin directories. It also includes hooks to regenerate ctags after certain Git operations. Key reusable components include the `git-up` script for rebasing onto the default branch and the `tat` script for tmux session management. These scripts are isolated, self-contained, and demonstrate practical solutions to common developer workflows. The configuration adapts to available tools (e.g., using ripgrep if present, falling back to the Silver Searcher) and incorporates modern practices such as using asdf for version management and setting up a safe bin path for trusted repositories.
