Open Semantic Search is a personal search engine that features full-text search, faceted search (interactive filters), tagging, annotation, and vizualisations (trend charts and, tag cloud, and word cloud) for documents, files, images, videos, tables, sheets, and news from different data sources such as file servers, RSS, databases, wiki, or CMS. It integrate Apache Solr with UI, connectors, semantic wiki for metadata management (tagging, annotation, and structured notes), OCR, and other tools.
QtIPy is a simple GUI-based automator for IPython notebooks. It allows you to attach triggers to files, folders, or timers to automatically run notebooks. IPython notebooks are great for interactively working through analysis problems, so why would you want to automatically run them? To get a record of how you ran your analysis! By running a notebook through QtIPy you get the output, figures, and a step by step log of how the analysis was performed all in the same folder.
RufasCube is a slider puzzle where there is a 3x3x3 arrangement of cubelets with the center one missing, allows sliding permutations. After a randomization, the goal is to restore the cube to its original configuration based on color and alphabetic hints. It is challenging, but not as difficult as a Rubik's cube. Here, diligence pays off. Also, incremental solution is possible - you can unscramble one slice at a time. When you finish, you can see the entire English alphabet appear on the 26 cubelets. It supports laptops and Mac Retina displays.
RufasGate is a combination of the Portal and Sokoban games. Using stargate terminology, there are Zero Point Modules (ZPMs) that power the portal guns, which in turn create the two ends of a temporary and short range wormhole, a shortcut through space-time, that allows obstacles to be bypassed. In order to empower the portal guns, all cylindrical ZPMs must be bumped onto their base receptacles. There are currently only four levels, and no way to save a game. RufasGate is also a testbed for learning/illustrating various modern OpenGL techniques including cubemaps, water reflections, sound, and glsl shader capabilities. For anyone planning to use SDL2, it illustrates key-mapping, to get improved keyboard responsiveness from SDL. It supports laptops and high DPI Mac Retina displays.
