LUCCA: Library of Utilities for C/C++ Astrodynamics
Tools: C/C++, Astrodynamics, Numerical Mathematics
The Library of Utilities for C/C++ Astrodynamics (LUCCA) is an open-source (MIT license) collection of methods and classes for solving both common and complex problems in aerospace engineering. It is designed and written in C/C++ for fast execution and near-universal platform support. Problems include a variety of propagation models, orbit determination, kinematics, launch models, and orbit controllers.
CUBEN: C/C++ Computational Numerics
Tools: C/C++, Numerical Mathematics
The C/C++ Computational Numerics library (CUBEN) is an open-source (MIT license) set of methods and classes for solving both common and complex problems in numerical mathematics. It is designed and written in C/C++ (leveraging the Eigen library for vector and matrix support) for fast execution and near-universal platform support. Problems include multiple root-finding algorithms, numerous methods for solving systems of equations, classes for modeling different categories of numerical functions, ODE and PDE solvers, pseudo-random number generation, least-squares tools, and many others.
QuX: Queried XML
Tools: C/C++, File I/O Data Interfaces, SQL, XMl
Queries XML (QuX) is an experimental proof-of-concept demonstrating an alternative to traditional XML interfaces for low-level languages like C++. I've found the traditional, official approaches to be very redundant, overly complex, heavy on resources, and overly abstract. Queries XML, or QuX, is a way to use traditional SQL-style SELECT, INSERT, and UPDATE queries to manipulate XML files and data structures. QuX is very useful for simple, lightweight serialization, state / data management, and other data-intensive operations that engineers frequently face. Developers needing to interface low-level code with XML data, like design requirements, will also find QuX useful.
Tools: Python, cherrypy
Thin-layer data server for providing uniform RESTful query access to a multitude of data formats by drag-and-drop copy, including tabular (.CSV, .XLSX, .SQL) and document (.JSON, .UNQ, .XML) formats. My first fully-deployed PyPi package! You can find the source code on GitHub. But what really gets crazy is when you use it to wrap an Excel spreadsheet in a Docker image. Drop-in containerized datastore with complete transparency and multi-table storage, for a single file!
Impulse web application toolkit
Impulse is an instantaneous web application starter kit. It is NOT a framework--there are no new programming languages, markups, or abstractions to learn that you don't probably already know. To create a new web application, you simple copy and paste the project contents into a new folder and bam! you're on your way! Check out the source code on GitHub to get started. When you're ready, building into a distributable installer or executable with electron-builder is a snap.
'Kirke' Website CMS
Tools: PHP, MySQL, HTML, CSS
Lightweight and node-based website CMS for management of personal websites, with database support and node abstraction for content, users, and other custom forms of data.
Post-Sparse Data Architecture Standards for Modern SSA
Tools: Systems Engineering, Data Architecting, DevSecOps
The volume and diversity of SSA data is increasing at an exponential rate, even as flight safety, security, and traffic management requirements impose greater demands on analysis and prediction such data drives. New tools, technologies, and development methods are required to keep pace with an evolving data environment and operator needs. Data architects must face the need to relax structure requirements to maintain flexibility in the face of a multiplicity of data fusees and widely-varying precision and accuracy.
We outline several key technologies that can enable rapid turnaround of software and pipeline architecting for an evolving SSA data environment. These include robust standards for both end-client and data-pipeline nodes across synchronous-poll and asynchronous-socket use cases. The end result is a near-real-time common analysis environment supporting collaborative users and transparent processing.
Procedural Vignette Generation
Tools: Systems Engineering, Space Architecting, Scenarios and Vignettes
Outlines an approach designed to procedurally generate vignettes for arbitrary architectures and mission areas, specific to given threat sets and scenario-driven contexts.
Resilience as Stability
Tools: Systems Engineering, Space Architecting, Controls Engineering
Proposes a methodology by which resilience of complex architectures can be construed and approached as a problem of stability in the control of an architecture. Controls techniques are applied to the architecting process to ensure satisfaction of resilience requirements.
Controls Engineering Overview
