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).

mp3splt is a free utility to split mp3, ogg vorbis and FLAC files without decoding, selecting begin/end time; if file is an album, you can get splitpoints automatically from internet or a local cue, cddb file. It also splits Mp3Wrap and AlbumWrap archives. Supports splitting and trimming by silence detection. For mp3 files, both ID3v1 and ID3v2 are supported using original tags or user defined tags.

wxMaxima is a cross-platform graphical front-end for the computer algebra system Maxima based on wxWidgets. It provides nice display of mathematical output and easy access to Maxima functions through menus and dialogs. This project has moved to github and can be reached at http://wxmaxima-developers.github.io/wxmaxima/

OpenJUMP is a community driven fork of JUMP the "Java Unified Mapping Platform" GIS software. The original JUMP was developed by Vivid Solutions, released under GPL2 in 2003 and discontinued in 2006. During 2004 already some enthusiastic developers joined together to enhance further the features of JUMP. They launched an independent development branch called OpenJUMP. The name gives credit to the original JUMP development, and at the same time describes the objectives of this project to be fully open to anyone wanting to contribute. These days OpenJUMP is developed and maintained by (some few) volunteers around the globe. If you need functionality or even better want to contribute you are very welcome to contact us at our mailing list.

Stellarium renders 3D photo-realistic skies in real time with OpenGL. It displays stars, constellations, planets, nebulae and others things like ground, landscape, atmosphere, etc.

3DimViewer is a lightweight 3D viewer of medical DICOM datasets that is distributed as open source software. The viewer is multiplatform software written in C++ that runs on Windows, Mac OS X and Linux systems. 3DimViewer source codes are available on Bitbucket (https://bitbucket.org/3dimlab/3dimviewer). Video tutorials can be found on YouTube (https://www.youtube.com/playlist?list=PLCvwUmKRw9ZO4YexLKEXmw_2jPo-kXVRn).

A multiplatform vector drawing program with a complete library of electronic symbols. Schematics and drawings are stored in a very compact text format. There is no netlist concept behind the drawings (so no simulation, and this is a choice) but this allows a great graphical flexibility and ease of use, making FidoCadJ the perfect tool for exchange sketches in forum and newsgroup discussions with a few clicks. Drawings can be exported in several graphic formats, such as pdf. Follow the development live on Twitter: https://twitter.com/davbucci

JSmol is the extension of the Java-based molecular visualization applet Jmol (jmol.sourceforge.net) as an HTML5 JavaScript-only web app. It can be used in conjunction with the Java applet to provide an alternative to Java when the platform does not support that (iPhone/iPad) or does not support applets (Android). Used in conjunction with the Jmol JavaScript Object (http://wiki.jmol.org/index.php/Jmol_Javascript_Object), JSmol seamlessly offers alternatives to Java on these non-Applet platforms. JSmol can read all the files that Jmol reads. You can do all the scripting that Jmol does. You can create all the buttons and links and such that you are used to creating for Jmol. All of the rendering capability of the Jmol applet is there. JSmol has both a console and a popup menu. JSmol is integrated fully with JSME and JSpecView. A "lite" version of JSmol provides minimal functionality (balls and sticks only) for extremely small-bandwith apps. Released 1/12/2013

The EdytorNC project now consists of four applications that can be useful for programming and operating CNC machine tools. EditorNC is a specialised text editor for CNC programmers. FTPserver is a simple FTP server for transferring cnc programs to and from the machine. SerialPortFileServer is a simple server for transferring cnc programmes to and from the machine via RS232 ports. ProgramManager is a program that makes it easy to search for cnc programs based on, for example, part number, part name contained in the first three comments in the cnc program. Some EdytorNC features : bolt holes calculation; solutions of triangles calculation; speed, feed calculation; conversion inch/mm, mm/inch; code colouring; RS232 data transmission with automatic file saving and possibility to download new CNC program directly from machine (beta function, look in tool tips in serial port configuration dialog). Clipboard to keep texts from system clipboard.

An easy to use application to design your kitchen garden or your house farm. Helps you plan your plants ( vegetables, fruit trees, herbs, flowers ) so that it respects the rules of crop rotation and companion planting. Based on square foot gardening. A fork of https://sourceforge.net/projects/kitchengarden. The windows installer contains all necessary files. A Linux and Mac package contains scripts and instructions to install the dependencies, and run KGA. If you download the jar directly, you must have Java 9+, including javafx. Oracle and OpenJDK java runtimes no longer include javaFX, and it must be separately installed. Alternatively https://www.azul.com/downloads/zulu-community/ is a JRE that provides a free 'JRE FX' installable that includes java and javafx. Installing it is the easiest way to run KGA on another OS. Kitchen garden aid is primarily tested on java 15, with javafx 15 on windows. If you notice a bug, especially on another OS please report it so I can fix.
