systemd_commander - TUI for managing systemd services
systemd_commander is a terminal user interface for managing systemd services and browsing journal logs. The project provides two closely integrated applications: systemd_commander for service management and journal_viewer for examining journal entries.
The software is built with ncurses and presents common systemd administration tasks through a keyboard-driven interface. Services can be inspected and controlled without repeatedly entering systemctl commands, while logs for a selected unit can be opened directly in the accompanying journal viewer.
Privileged operations are requested only when necessary rather than requiring the complete interface to run as root.

IntelOwl - threat intelligence enrichment and analysis platform
IntelOwl is a threat intelligence management and enrichment platform built to reduce the manual work involved in checking files and observables across many separate sources.
Security analysts can submit items such as IP addresses, domains, URLs, hashes or files and orchestrate multiple analysis and intelligence services from one system. It combines external intelligence lookups with locally available malware-analysis tooling, making it useful for SOC workflows, investigations and repeatable enrichment pipelines. Results can be examined through its web interface or consumed programmatically by other security applications.

paint.software – Paint.NET-style raster image editor for Linux
paint.software is a native raster image editor for Linux that follows the layout and editing model of Paint.NET without requiring Wine or the .NET runtime.
Built with C++17 and Qt 6, it is intended for drawing, quick image corrections and layered editing in a conventional desktop interface. Its workspace combines a central canvas with tool, colour, layer and history controls.

Verilator - SystemVerilog simulator and lint system
Verilator is a SystemVerilog simulator and lint system aimed at high-performance digital design verification.
Unlike an event-driven interpreter, it translates Verilog and SystemVerilog designs into compiled C++ or SystemC models which can then be built into native executables. Linting is integrated into the same frontend, allowing the parser and elaborator to identify questionable constructs without generating a simulation model. This combination makes Verilator useful both as a standalone code checker and as part of larger verification environments where simulation speed, standards checking and automated source analysis are important.

StaticPipes – flexible pipeline-based static site generator
StaticPipes is a Python static website generator designed around configurable pipelines rather than imposing a particular project structure or publishing workflow.
A site is assembled from a collection of pipes and processes selected by the developer. Each pipe performs a task such as copying files, rendering templates or transforming assets. Processes can also be chained so that a source file passes through multiple operations before reaching the generated site. Developers with specialist requirements can extend the supplied base classes and add their own processing logic.
StaticPipes also treats checking the generated website as part of the build process rather than an entirely separate task.

Meloville - local music player
Meloville is a desktop music player designed for listening to and managing a local music collection.
Meloville takes a more visual approach than many traditional Linux music players, with album artwork playing a prominent role throughout the interface. Besides the usual library and playlist functionality, there are synced lyrics, metadata editing, a full-screen Big Picture mode, MPRIS integration and a feature for sharing the currently playing track with another listener.

Open Video Downloader – cross-platform yt-dlp GUI
Open Video Downloader is a cross-platform graphical frontend for yt-dlp that makes downloading media from supported websites accessible without working directly at the command line.
Users can add individual videos or playlists, inspect the available options, choose how the resulting media should be produced, and follow download progress from the desktop interface. The application uses a Vue 3 frontend with a Tauri/Rust backend, which communicates with yt-dlp to obtain media information and perform downloads. Despite retaining the youtube-dl-gui repository name, current versions are built around yt-dlp.

Chili3D – browser-based 3D CAD application
Chili3D is a browser-based 3D computer-aided design application for creating and editing solid models directly in a web browser. Its modelling engine is based on OpenCascade, compiled to WebAssembly, while Three.js handles the interactive 3D viewport.
The application is designed around a conventional CAD workflow rather than a simplified model viewer. Users can create sketches, build solids from profiles, modify geometry, organise parts hierarchically, and save projects in browser storage. A ribbon-style interface groups modelling and editing commands, with a project tree and property panels for working with model structure and parameters.

JS Paint – classic MS Paint recreation with modern features
JS Paint is a web-based recreation of classic Microsoft Paint that closely reproduces its familiar tools, menus and workflow while extending the experience for modern systems.
It can be used in a browser or as an Electron desktop application, with packaged Linux builds available. The project is aimed at straightforward raster drawing and image editing, retaining the deliberately simple character of older Paint releases while removing some of their practical limitations.

svlint - configurable SystemVerilog linter
svlint is a command-line linter for SystemVerilog source code.
It is built on the sv-parser parsing library and is designed around a configurable collection of rules rather than a fixed coding policy. Projects can enable the checks they need, use supplied rulesets aimed at different development scenarios, or maintain their own configuration in the source tree. This makes svlint useful for both straightforward syntax and style checking and more specialised hardware-development policies covering design and verification code. It can also participate in editor workflows through the related svls language server.
