fluid-sims. Collection of high-performance, CUDA-accelerated fluid dynamics and physics simulators, including SPH, hypersonic flow, and reaction-diffusion systems.

pg_os. PostgreSQL extension providing operating system-level functionality directly through SQL, enabling process management, file system operations, IPC, and system monitoring within the database environment.

Ghast. Security auditing and remediation tool for GitHub Actions workflows that detects vulnerabilities, misconfigurations, and anti-patterns based on industry best practices.

pg_shell. Stateless, auditable, and replayable command shell built entirely on PostgreSQL and htmx. It replaces persistent shell processes with database-backed terminal sessions, where every command, output, and environment change is recorded in real-time.

an-ki. Distributed neural network project built with Rust that supports task scheduling, load balancing, and fault tolerance across a network of nodes. It leverages asynchronous operations, leader election, and health monitoring to ensure high availability and scalability for secure inter-node communication.

raft-vm. A lightweight VM designed to provide concurrency, fault tolerance, and actor-based message-passing models.

Capsule-UI. A UI architecture enforcing component isolation via Shadow DOM and CSS Modules. Features zero-runtime styling, container queries, and seamless micro-frontend integration for React, Vue, and Svelte.

pg_git. PostgreSQL-native Git implementation providing full version control functionality including core operations, branching, merging, and remote transport directly within the database..

XORM. ⊕, macros, and two 8-bit registers. That's all you get.

nlp-dump. Use Spacy to save out linguistic data in various formats.

SpacyVis. XML annotation visualizer with interactive highlighting.

pg_gpt2. Complete implementation of the GPT-2 architecture entirely inside PostgreSQL, featuring a native tensor engine, autograd, and AdamW optimization for end-to-end training and inference via SQL.

4splat. Binary format and reference implementation for 4Splat (.4spl). Palette-based, lossless 4D video codec that generalizes indexed-color images to spatial-temporal data with Gaussian splats
