My personal (public) NixOS configurations and common Nix(OS) modules, pkgs, and libs.

Generic gpio driver for the tm1637 microcontroller written in Rust.

CLI utility to support you with your time logs in GitLab.

Provides pre-rasterized characters from the "Noto Sans Mono" font in different sizes and font weights for multiple unicode ranges.

Audio beat detection library that supports different audio input devices as source. You can pass a callback for each found beat to the library.

Simple audio visualization library which is especially useful for developers to visually check audio algorithms against the waveform.

A multithreaded bruteforce library written in Rust. PLEASE DO NOT use this software to harm someones privacy in any kind! This project was made for fun and for teaching myself new things about Rust.

A simple demo with UEFI using the serial device for a chat.

Your small yet useful swiss army knife for the `fcntl` system call, specifically for acquiring and testing file locks, but not limited to those.

Web-app to convert bin/oct/dec/hex, interpret data as float(IEEE-754), interpret as different integer types, and to show memory endianness.

The crate `tokio-js-set-interval` allows you to use `setInterval(callback, ms)` and `setTimeout(callback, ms)` as in Javascript inside a `tokio` runtime (https://tokio.rs/).

Library to read Tar archives (by GNU Tar) in `no_std` contexts with zero allocations. The crate is simple and only supports reading of "basic" archives, therefore no extensions, such as GNU Longname.

Docx4JSRUtil library helps you to search and replace text inside docx-Documents parsed by Docx4J.

Library + CLI-Tool to measure the TTFB (time to first byte) of HTTP requests. Additionally, this crate measures the times of DNS lookup, TCP connect and TLS handshake.

Minimal CMake-based project building a trivial C++ library with Catch2-based unit tests.

Small no_std-lib that checks if the binary is running inside a QEMU virtual machine. Only works on x86/x86_64 platform.

CLI utility that helps you to calculate indices into the page table from a virtual address. For x86, it outputs the indices into the page tables for both, 32-bit and 64-bit paging.

A demo bash-like shell for educational purposes - shows basics about pipes, fork and a lot of other UNIX facilities.

All-in-one binary to convert decimal/bin/oct/hex + interpret data as i8-i64, u8-u64, and f32/f64 (IEEE-754).

My public Slidev slides.

An easy to use and fast `no_std` library (with `alloc`) to get the frequency spectrum of a digital signal (e.g. audio) using FFT.

A parser and builder for the Linux process initial stack layout - use it to decode or construct argc, argv, envp, and auxv (auxiliary vector).

A Linux driver for the QEMU Debugcon device packaged in Nix.
