Git Smart HTTP served by disposable nodes, while MinIO holds the authoritative write-ahead log, refs and snapshots.

• Pushes commit with a conditional If-Match write on the head object instead of a leader
• Nodes rebuild their caches from a snapshot plus WAL replay; HMAC-signed UDP gossip is only a speed-up
• Failpoints, chaos and concurrency scripts, and a read-only React console for WAL and node health

Educational and local-only by design.

Personal finance app with a Go (Gin) clean-architecture backend on PostgreSQL and a Next.js front end.

• PostgreSQL row-level security isolates each user's data inside the database
• Trigger-based audit trail snapshots rows before and after changes on eight financial tables
• Refresh-token rotation with reuse detection, rate limiting, background workers and SSE notifications

A long-running learning playground.

Atomis

Native apps & developer tools · updated Sep 2026

Local-first code playground for Zig, Rust, Go, TypeScript, Python, C and C++, with Monaco, real language servers, native execution and inline runtime values.

• Rust/axum orchestrator speaks a WebSocket protocol to a React and Monaco UI
• Inline values come from per-language AST instrumentation, without changing the visible code
• A Linux Landlock sandbox confines each session to its workspace, with no TCP

sbql

Native apps & developer tools · updated Aug 2026

SQL workspace on a headless Rust core, with a Ratatui terminal UI and a native SwiftUI macOS app for PostgreSQL, SQLite and Redis.

• The core owns connections, pagination, schema introspection and mutations; UIs are thin clients
• Sorting and filtering rewrite the SQL syntax tree instead of concatenating strings
• The SwiftUI app calls the same Rust engine through UniFFI; passwords live in the system keyring

Lectern

Native apps & developer tools · updated Sep 2026

Native Linux PDF reader in Zig that renders with Poppler and Cairo behind an SDL3 interface, with bookmarks, dark mode and freehand notes.

• A background worker pre-renders neighbouring pages so turning a page never blocks the window
• Notes autosave to an atomically written sidecar file; the PDF itself is never modified
• The idle window uses no CPU, and native tests compare screenshots against golden images

ghline & diffline

Native apps & developer tools · updated Aug 2026

Two Rust terminal interfaces: ghline browses GitHub through the gh CLI, diffline reviews a local diff and sends line-anchored notes to a coding agent.

• One shared crate (palette, fuzzy matcher, lexer, drawing primitives) behind two binaries
• Review notes are anchored to file lines, not screen rows, and sent as one grouped message
• Release archives ship with SHA-256 checksums and GitHub provenance attestations

hitt

Native apps & developer tools · updated Mar 2026

Terminal API client in Rust: a TUI and a scriptable CLI for HTTP collections, environments, request chaining, assertions, load tests, WebSocket and SSE.

• Imports cURL, Postman, OpenAPI 3 and HAR; exports cURL, Postman and Markdown docs
• Request chains pull values out with JSONPath, headers or cookies and pass them to the next step
• Built-in load testing reports p50 to p99 latency

Work in progress; gRPC execution is not wired up yet.
