2025-01-06

42: A Powerful Spacecraft Attitude Control System Simulator

42 is a comprehensive general-purpose simulation of spacecraft attitude and orbit dynamics, primarily used to support the design and validation of attitude control systems throughout their lifecycle, from concept studies to integration and test. It accurately models multi-body spacecraft attitude dynamics (rigid and/or flexible bodies), and both two-body and three-body orbital flight regimes, simulating environments from low Earth orbit to throughout the solar system. 42 simulates multiple spacecraft concurrently, facilitating studies of rendezvous, proximity operations, and precision formation flying. It also features spacecraft attitude visualization.

Low-Cost Live Image Description for the Visually Impaired: ESP32-CAM + Phone + Server

This project details a low-cost, live image description solution for the visually impaired, using an ESP32-CAM, a phone, and a server. The ESP32-CAM captures images at set intervals, which are then sent to an OpenAI API for description. The description is relayed to the user via a webpage on their phone, read aloud via text-to-speech. While the current prototype has limitations—requiring manual camera handling and lacking robust security—it demonstrates the feasibility of the approach and lays groundwork for future development of more sophisticated assistive tools.

Beam: SSH-based File and Pipe Transfer Tool

Beam is a tool for transferring files and pipes over SSH, requiring only an SSH client; no binary installation is needed. It supports pipe transfer, offers high security with public key authentication, and uses simple SSH commands for sending and receiving data. Random channel names can enhance security. While the Beam server is located in Germany, transfer speeds might be limited, and end-to-end encryption isn't supported (data is briefly decrypted on the server), its lightweight nature and simple self-hosting make it a convenient file transfer solution.

Transcendental Syntax: Building Logical Abstractions from a Low-Level Language

This GitHub project implements Jean-Yves Girard's 'Transcendental Syntax,' a method for constructing logical abstractions from a low-level, logic-agnostic language. It uses a base language called 'stellar resolution,' where elementary objects (programs) are 'constellations.' These constellations are used in a higher-level language, 'Stellogen' (a metaprogramming language for constellations), to define proofs and formulas. The project is under development, with the guide currently only available in French.

F-Droid Fake Signer PoC: Bypassing Certificate Pinning

F-Droid Fake Signer PoC: Bypassing Certificate Pinning

This project is a proof-of-concept demonstrating vulnerabilities in F-Droid's APK signature verification. Attackers can exploit these flaws to forge signatures, bypassing F-Droid's certificate pinning and allowing malicious apps to masquerade as legitimate ones. The vulnerabilities stem from inconsistencies in how F-Droid handles certificate order and verification within the APK signing block. By manipulating these inconsistencies, attackers can inject false certificate information, tricking F-Droid into accepting them as valid. While fixes have been proposed and implemented, further vulnerabilities and bypasses have been discovered, highlighting ongoing challenges in securing APK signing verification.
