GRADIS/GRADIFF

GRADIS is an in-development graphing and diagramming application, based on the GRADIFF file format.

GRADIFF is a file format optimized for maintaining diagrams in source control, with an emphasis on clean and readable diffs. Alongside the formal specification of GRADIFF comes a Rust-based, high-test-coverage reference implementation library, as well as an experimental Cairo-based renderer.

./badges

./badges (dot-slash-badges) is a text-to-path SVG renderer for README badges that comes with a built-in CC0 template and font.

While ./badges is a CLI tool, a prototype web server with corresponding Vue.js-based frontend was built as ./badges web.

For Version 3 of ./badges, a Rust-based rewrite is planned, enabling a WASM port and client-side-only version of ./badges web.

calendity

calendity is a template project for setting up an Eleventy-based statically generated event bulletin board.

toc-extract

toc-extract is a package for Node.js that can be used to extract a Table of Contents from HTML, using JSDOM.

Additionally, toc-extract defines a filter for the static site generator Eleventy.

vtproto

vtproto is a Protocol Buffers-based data format for Vibrotactile Patterns that I designed as part of my diploma thesis.

libvtp / vtp.js (deprecated)

libvtp is a C library for encoding and decoding vibrotactile patterns that I wrote as part of my diploma thesis. It has been superseded by vtproto.

vtp.js is a manual (i.e. not Emscripten-based) JavaScript port of libvtp.

synthesizer

A work-in-progress project to build a synthesizer from scratch using MIDI and STM32.

eieruhr

A simple, AVR-based kitchen timer that I made as a toy project in college.

KISStokens

KISStokens was a Go library for signing, verifying and decoding authentication tokens following the JSON Web Signature (JWS, RFC7515) and JSON Web Token (JWT, RFC7519) standards.

I have developed a number of working releases, but decided to discontinue KISStokens since the project that it was intended to be a part of did not materialize and I have since moved on to Rust.

xeDB

xeDB was an attempt at writing a database specifically geared and empirically optimized towards the Event Sourcing use case.

The project has been put on hold, mainly for a lack of a practical use, but I'm considering to pick it back up since it still would be a nice and educational side project.
