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).

Karto allows to calibrate a scanned map (or aerial photos) with some known geo-points (Lambert, UTM, ...). After that, you can add any points (GPS points) in the map to build your own map. You can also add a transparent GIF image in the map after calibration (cave, mines, roads, ...). You can realize your own cartes with the data you add inside adding/showing/hiding layers of data. You can import/export your data files (after checking and correcting them) in differents formats.

Adele was developed to simplify the daily work with data. Use it as a swiss knife to fill the gap between your work with spreadsheet application like MS Excel and enterprise servers like SAP ERP. Specialized tools like Rapid Miner, KNIME or similiary stuff should not be replaced. But Adele is designed for business people working with spreadsheet applications to analyse their data. There are many technical concepts in an easier way included. For example realtime OLAP, transformations, charts, analysis tools,... Connectors (e.g. JDBC, SAP ABAP, OData) can be used to pre-analyse the data and extract it without saving the data as text files. A plugin concept for enhancements are available. Enjoy! Its free for commercial use too. Adele runs without installation from USB stick for Windows, Linux and MacOSX. Last added changes: - data science tools (V1, IQR) - export to remote and desktop databases (mysql,sqlite, ms access) - internet features for emails and domains
