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).

CLISP is a portable ANSI Common Lisp implementation and development environment by Bruno Haible. Interpreter, compiler, debugger, CLOS, MOP, FFI, Unicode, sockets, CLX. UI in English, German, French, Spanish, Dutch, Russian, and Danish.

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/

A web based Metadata Catalog Server for data description and discovery. Supports both generic and geospatial data discovery. It implements international standards (e.g. ISO19115/19139/19119, ISO19115-3, DCAT-AP, CSW 2.0, OGC API Records). It originates from the United Nations and is used by many governments as geoportal software. Active development and discussion takes place on GitHub and OSGeo Discourse. You can also connect directly with the companies supporting the development. Source code available on github https://github.com/geonetwork/

Modular, touch screen friendly navigation system with GPS tracking, realtime routing engine and support for various vector map formats. Works on a wide range of devices, from computers to smartphones.

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
