    2018 Thomson Reuters Top 100 Global Tech Leaders Icon

    See how tech-sector leadership is being redefined in today’s complex business environment.

    21st century technology-sector leadership requires not only optimal financial performance but also attention to many other factors, including management and investor confidence, risk and resilience, legal compliance, innovation, environmental impact, social responsibility, and reputation. Successfully managing these areas may determine which tech companies have the fortitude to succeed in the future. Here’s to those that made the list.
    Who are today’s top global tech leaders?

  • FreeCAD Icon

    FreeCAD

    a parametric 3D CAD modeler

    WARNING: FreeCAD has moved! FreeCAD code and release files are now hosted on github at https://github.com/FreeCAD/FreeCAD Only older files and code are available here. FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is 100% Open Source and extremely modular, allowing for very advanced extension and customization. FreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms.

  • Eagle Mode Icon

    Eagle Mode

    Zoomable user interface (ZUI) with file manager, file viewers and more

    Eagle Mode is a zoomable user interface (ZUI) with file manager, file viewers, games, and more. This project is about a futuristic style of human-computer interaction, where the user can visit almost everything simply by zooming in. It features a portable C++ toolkit API for developing such ZUIs, and it features the Eagle Mode application, which provides a virtual cosmos with plugin applications. The most important one is the professional file manager with its rich, scriptable command set. It integrates file viewers for most of the common file types, as well as an audio and video player. Furthermore, the virtual cosmos contains a chess game, a netwalk game, a 3D minesweeper game, a world clock, some fractal fun, and a Linux kernel configurator in form of a kernel patch. Eagle Mode runs best on Linux, but there is also a light version for Windows, which lacks some of the plugins.

    Pioneers is an emulation of the board game The Settlers of Catan, which can be played over the internet.

  • Presage

    the intelligent predictive text entry platform

    Presage (formerly Soothsayer) is an intelligent predictive text entry system. Presage generates predictions by modelling natural language as a combination of redundant information sources. Presage computes probabilities for words which are most likely to be entered next by merging predictions generated by the different predictive algorithms. Presage's modular and extensible architecture allows its language model to be extended and customized to utilize statistical, syntactic, and semantic predictive algorithms. Presage's predictive capabilities are implemented by predictive plugins. Predictive plugins use services provided by the platform to implement multiple prediction techniques.

  • FractalNow Icon

    FractalNow

    Fast, advanced, multi-platform fractal generator

    FractalNow provides users with tools to generate pictures of various types of fractals quickly and easily. It is made of both a command line tool, FractalNow, and a graphical tool, QFractalNow. The graphical tool, based on Qt library, allows users to explore fractals intuitively and generate pictures. Both tools are entirely multi-threaded and implement advanced algorithms and heuristics that make computation very fast compared to most existing free fractal generators.

  • SASfit Icon

    SASfit

    A program for fitting structural models to small angle scattering data

    SASfit has been written for analyzing and plotting small angle scattering data. It can calculate integral structural parameters like radius of gyration, scattering invariant, Porod constant. Furthermore it can fit size distributions together with several form factors including different structure factors. Additionally an algorithm has been implemented, which allows to simultaneously fit several scattering curves with a common set of (global) parameters. This last option is especially important in contrast variation experiments or measurements with polarised neutrons. The global fit helps to determine fit parameters unambiguously which by analysing a single curve would be otherwise strongly correlated.
