AGAMA in a library for galaxy modelling. Its main tasks include:

• Computation of gravitational potential and forces;

• Orbit integration and analysis;

• Conversion between position/velocity and action/angle coordinates;

• Distribution functions;

• Self-consistent multi-component galaxy models;

• Framework for finding best-fit parameters of a model from data;

BBarolo 3D fitting tool to derive the kinematics of galaxies from emission-line observations.

NAIF is a pure-python package for numerical analysis of frequencies. It implements the NAFF algorithm introduced by Laskar (1990, 1999) and further developed by Valluri & Merritt (1998) – see also Price-Whelan et al (2016) and their released package SuperFreq. It is based on the Fortran implementation of Valluri & Merritt (1998), but it introduces a few improvements. It is also intended to be a transparent, well documented and easy-to-use implementation.

code of the method described in Dehnen W., Semczuk M., Schönrich R., 2022, MNRAS, 518, 2712

pytreegrav is a package for computing the gravitational potential and/or field of a set of particles. It includes methods for brute-force direction summation and for the fast, approximate Barnes-Hut treecode method. For the Barnes-Hut method we implement an oct-tree as a numba jitclass to achieve much higher peformance than the equivalent pure Python implementation, without writing a single line of C or Cython.

NEMO is a toolbox for stellar dynamics, particle simulations, stellar orbits, image processing and tabular data manipulation.

PortableXDR is an implementation of External Data Representation (XDR) Library. It is a standard data serialization format, for uses such as computer network protocols. It allows data to be transferred between different kinds of computer systems.

NEMO is a toolbox for stellar dynamics, particle simulations, stellar orbits, image processing and tabular data manipulation.

The aim of this version is just to get the core library libnemo.a and a few binaries right, so many scripts and tools were already (or would be eventually) removed.

VorBin package is a Python implementation of the two-dimensional adaptive spatial binning method of Cappellari & Copin (2003). It uses Voronoi tessellations to bin data to a given minimum signal-to-noise ratio.

A python wrapper to unsio

UNSIO ( U niversal N body S napshot I nput O utput) is an API which perform input/output operations in a generic way, and on different kind of nbody files format (nemo, gadget, sqlite3 etc).

GNOME Topbar is a Wayland-only GTK top bar inspired by GNOME Shell. It provides a continuous system panel with notifications, quick settings, media controls, workspaces, and custom script modules.

SpaceSniffer1000 is an egui desktop application for exploring filesystem usage with a clickable treemap.

Pinentry Fuzzguy is a small Guile pinentry implementation for Wayland. It uses Fuzzel for passphrase prompts, displays context supplied by gpg-agent, and falls back to pinentry-tty when a graphical prompt is unavailable.

Emacs built from the wlshm-backend branch of trevarj's fork, which adds a raw Wayland plus CPU Cairo-on-wl_shm rendering backend enabled with --with-wlshm. Inherits emacs-next.

This Emacs build implements graphical UI purely in terms of GTK.

kg is a small terminal text editor with pure Emacs-style keybindings, syntax highlighting, multiple buffers, split windows, incremental search, undo, and VT100 terminal support without a curses dependency.

A font for cryptocurrency symbols

My custom Iosevka font inspired by JetBrains Mono.

Execute multiple shell commands periodically with separate intervals and display the output in GNOME Shell's top bar.

Guixboy provides a Guile command-line interface for common Guix System maintenance workflows, including configured reconfiguration targets, update checks, substitute URL aliases, garbage-collection recipes, profile discovery, and beginner-oriented explanations.

Guix Weather Plus is a Guix extension that estimates whether a normal Guix pull followed by system or home reconfiguration is likely to use available substitutes instead of local builds.

Helpers that drive the personal mail flow: credential lookup from authinfo.gpg and staging deletions as Maildir flags (Guile), plus manual sync and GNU list archive imports (POSIX shell). Notmuch tagging is handled by the notmuch-mbsync service's tag rules.

yoink is a terminal music browser: browse MusicBrainz, queue full albums, and a background worker crawls YouTube Music and downloads each track with yt-dlp, tags it, and writes a clean Artist/Album/NN Title.opus library tree. Output is plain files; syncing elsewhere is left to the user.
