    Octave Forge

    Octave Forge

    A collection of packages providing extra functionality for GNU Octave

    Octave Forge is a central location for collaborative development of packages for GNU Octave. The Octave Forge packages expand Octave's core functionality by providing field specific features via Octave's package system. See https://octave.sourceforge.io/packages.php for a list of all available packages. GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable. Refer to https://www.octave.org for more information.

    Jmol

    Jmol

    An interactive viewer for three-dimensional chemical structures.

    Over 1,000,000 page views per month. Jmol/JSmol is a molecular viewer for 3D chemical structures that runs in four independent modes: an HTML5-only web application utilizing jQuery, a Java applet, a stand-alone Java program (Jmol.jar), and a "headless" server-side component (JmolData.jar). Jmol can read many file types, including PDB, CIF, SDF, MOL, PyMOL PSE files, and Spartan files, as well as output from Gaussian, GAMESS, MOPAC, VASP, CRYSTAL, CASTEP, QuantumEspresso, VMD, and many other quantum chemistry programs. Files can be transferred directly from several databases, including RCSB, EDS, NCI, PubChem, and MaterialsProject. Multiple files can be loaded and compared. A rich scripting language and a well-developed web API allow easy customization of the user interface. Features include interactive animation and linear morphing. Jmol interfaces well with JSpecView for spectroscopy, JSME for 2D->3D conversion, POV-Ray for images, and CAD programs for 3D printing (VRML export).

    Upscayl

    Free and Open Source AI Image Upscaler for Linux, MacOS and Windows

    Free and Open Source AI Image Upscaler for Linux, MacOS and Windows built with Linux-First philosophy. Upscayl is a cross-platform application built with the Linux-first philosophy. This means that we prioritize Linux builds over others but that doesn't mean we'll break things for other OSes. Upscayl does not work without a GPU, sorry. You'll need a Vulkan-compatible GPU to upscale images. CPU or iGPU won't work. You can also download the flatpak version and double-click the flatpak file to install via Store but wait for the full release, we'll be pushing it to Flathub for easy access. Upscayl uses AI models to enhance your images by guessing what the details could be. It uses Real-ESRGAN (and more in the future) model to achieve this. The CLI tool is called real-esrgan-ncnn-vulkan and it's available on the Real-ESRGAN repository.

    Yet another cross-platform graphical process/system monitor

    Yet another cross-platform graphical process/system monitor. A customizable cross-platform graphical process/system monitor for the terminal. Supports Linux, macOS, and Windows. Inspired by gtop, gotop, and htop. By default, bottom is somewhat like a dashboard - a bunch of different widgets, all showing different things, and they all cram together to fit into one terminal. If you instead just want to see one widget, maybe you want to look at a graph in more detail, for example, you can "expand" the currently selected widget using the e key, which will hide all other widgets and make that widget take up all available terminal space. To allow for widget-specific keybindings and expansion, there is the idea of widget selection in bottom, where you can focus on a specific widget to work with it. This can be done with the mouse (just click on the widget of interest).

    Excalidraw

    Virtual whiteboard for sketching hand-drawn like diagrams

    Excalidraw, the virtual whiteboard app for sketching hand-drawn like diagrams, has come a long way. With the remote work becoming the status quo, Excalidraw was able to show its true potential and we’ve come to a point where over 100K people have used it just the last month! While it has been extremely successful as a free open source project, the biggest source of complaints nowadays is around adoption within companies: How do you share diagrams with your co-workers easily? Can your company depend on the service for live collaboration? Is your data secure? We’ve thought long and hard about how to make it happen in a volunteer-based open source model but haven’t found a great solution. So we decided to build a company around Excalidraw with the first product being Excalidraw+. With account-based access you can rest assured only the right people will have access to your data, while still retain the ability to share specific drawings with outside collaborators.
