RawTherapee is a powerful, cross-platform raw photo processing program. It is written mostly in C++ using a GTK+ front-end. It uses a patched version of dcraw for reading raw files, with an in-house solution which adds the highest quality support for certain camera models unsupported by dcraw and enhances the accuracy of certain raw files already supported by dcraw. It is notable for the advanced control it gives the user over the demosaicing and development process.RawTherapee is designed for developing raw files from a broad range of digital cameras, as well as HDR DNG files and non-raw image formats (JPEG, TIFF and PNG). The target audience ranges from enthusiast newcomers who wish to broaden their understanding of how digital imaging works to semi-professional photographers. Knowledge in color science is not compulsory, but it is recommended that you are eager to learn and ready to read our documentation (RawPedia) as well as look up basic concepts which lie outside the scope of RawPedia, such as color balance, elsewhere.Of course, professionals may use RawTherapee too while enjoying complete freedom, but will probably lack some peripheral features such as Digital Asset Management, printing, uploading, etc. RawTherapee is not aimed at being an inclusive all-in-one program, and the open-source community is sufficiently developed by now to offer all those peripheral features in other specialized software.

A simple desktop recorder for Linux systems. Built using Rust, GTK+ 3 and ffmpeg. It supports recording audio and video on almost all Linux interfaces with support for Wayland display server on GNOME session. The following formats are currently supported: mkv, avi, mp4, wmv, gif and nut (And only WebM for Wayland's GNOME session). You can stop the recording process easily by right-clicking the icon and choosing "Stop Record". Or middle-clicking the recording icon in the notifications area (but doesn't work on all interfaces). You can choose the audio input source you want from the list. You can also set the default values you want by simply changing them in the interface, and the program will save them for you for the next time you open it. Based on GREEN RECORDER but rewritten in RUST

OpenSCAD is a software for creating solid 3D CAD models. Unlike most free software for creating 3D models (such as Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. Thus it might be the application you are looking for when you are planning to create 3D models of machine parts but pretty sure is not what you are looking for when you are more interested in creating computer-animated movies.OpenSCAD is not an interactive modeller. Instead it is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file. This gives you (the designer) full control over the modelling process and enables you to easily change any step in the modelling process or make designs that are defined by configurable parameters.OpenSCAD provides two main modelling techniques: First there is constructive solid geometry (aka CSG) and second there is extrusion of 2D outlines. As data exchange format for this 2D outlines Autocad DXF files are used. In addition to 2D paths for extrusion it is also possible to read design parameters from DXF files. Besides DXF files OpenSCAD can read and create 3D models in the STL and OFF file formats.
