Forkcast Hacker News #13: latticedb, CarWatch, texbrain, kern, ambient-context, vpsmon, adi2

Episode Summary#

Episode 13 covers 30 open-source projects trending on Hacker News, including an embedded graph database with vector search in a single file, a Raspberry Pi car AI running a 35B parameter model offline, a browser-based LaTeX editor via WebAssembly, a 1.5MB container runtime with zero RAM at rest, a macOS menu bar app that logs your work through the accessibility tree, a lightweight VPS monitor in Go, and a modern GUI library for Ada with CSS styling.

Repositories Covered#

latticedb#

Embedded single-file knowledge graph database with vector search and full-text search for AI/RAG apps

CarWatch#

Your car as a chat-room agent: Raspberry Pi 5 + dashcam + local AI. CodeWatch’s sibling for the garage.

texbrain#

FOSS browser-based latex editor with live preview, real-time collaboration, and git integration.

kern#

A fast, rootless sandbox and virtual resource runtime for any workload, including untrusted and AI-generated code. Daemonless: a real, kernel-enforced container in ~3.5 ms from an OCI image, no daemon, one 1.52 MB static binary.

ambient-context#

A menu bar app that keeps a written record of what you worked on.

vpsmon#

Lightweight system monitor for Linux VPS

adi2#

A modern GUI library for Ada: CSS styling, XML UI, SDL3

steppewm#

minimal stacking wayland window manager

zcomplete#

Mistype a command and zcomplete runs the one you meant, worked out from the commands you usually run. zsh, bash and fish.

Tblue#

Passive blue-team security scanner — 582 read-only modules, plus 32 opt-in probes. Runs on your machine. No accounts. No telemetry.

emacs-zero-to-ide-journey#

My Emacs Zero to IDE Journey

neostatic#

A small neocities static blog generator

pktscope#

Wireshark-style terminal packet analyzer on eBPF/TCX — live packet list, protocol detail tree, section-colorized hex; works on raw-IP tunnel devices

api#

OpenMRP’s public API.

MajinBook#

An open catalogue of world literature with likes

mulmoterminal#

Run multiple Claude Code and Codex sessions in parallel — a browser terminal grid that shows which agent needs you. Local, tmux-backed, MIT.

reachpad-cli#

The reachpad CLI: workspaces where Claude, Codex and other coding agents build full-stack apps and share them by link, from your terminal.

sillage#

Your language model forgets everything. Sillage gives it a 4 MB memory that persists across sessions, no gradients, no fine-tuning, no growing index. Beats an unbounded kNN-LM at 1/13 the storage (perplexity 31 → 17). CPU-only, fully reproducible, four preprints with Zenodo DOIs.

cot-redteam-agent#

Red-team visible LLM reasoning — refusal quotes aren’t success. Adaptive TUI, CI scan, OWASP tags, mock provider, proof-of-action agent lane.

netra-kernel#

Open-source AMDGCN kernels for optimizing LLM inference

Orion#

A backend and automation language compiled to bytecode in Rust. One binary, 58 built-in modules, no runtime to install.

defragger#

Linux filesystem defragger written in Rust and Qt Quick/Kirigami

typeclip#

Types your clipboard with human cadence — built for screen recordings

orbit#

Multi-repo Git workspaces for any coding agent — real worktrees, no index, no server

pyrift#

Detect silent Python behaviour differences across CPython versions and CPython vs PyPy

nonograms#

Nonograms TUI

MNEMOSYNE#

The Autonomic Observational Existence Verification System

Graphlib#

Graphlib is a C++ library that empowers users to create and edit graphs!

sktime-cli#

The unofficial CLI client for sktime framework

cuda-metal#

CUDA compiler and runtime for Apple Silicon
