    SimpleXlsxWriter

    C++ library for creating XLSX files for MS Excel 2007 and above.

    This library represents XLSX files writer for Microsoft Excel 2007 and above. The main feature of this library is that it uses C++ standard file streams. On the one hand it results in almost unnoticeable memory and CPU resources consumption while processing (that may be very useful at saving a large data arrays), but on the other hand it makes unfeasible to edit data that were written.

    LevelDB

    LevelDB

    A fast key-value storage library

    ...Written at Google, it contains keys and values that are arbitrary byte arrays, ordered within the key value store according to a user-specified comparator function. LevelDB is not an SQL database and does not support SQL queries or indexes. It simply provides an ordered mapping from string keys to string values. Data is stored already sorted by key, though callers can override the sort order through a custom comparison function. It supports forward and backward iteration as well as transient snapshots, and automatically compresses data via the Snappy compression library.

    gradslam is an open source differentiable dense SLAM library

    gradslam is an open-source framework providing differentiable building blocks for simultaneous localization and mapping (SLAM) systems. We enable the usage of dense SLAM subsystems from the comfort of PyTorch. The question of “representation” is central in the context of dense simultaneous localization and mapping (SLAM). Newer learning-based approaches have the potential to leverage data or task performance to directly inform the choice of representation.
