Miller is a command line tool that combines features from sed, awk, cut, join, and sort. It works best on name-indexed CSV input, and thus allows easy cutting, sorting or filtering on column names. It allows pretty-printing of tabs/columns, format conversions, can be used in shell pipes like simpler tools, adds some SQL-like querying features, and is similar in spirit to "jq" the JSON queryer.
VIPS is a small, quick and memory-conservative 2D image processing C and C++ library. It comes with over 300 functions, for arithmetic processing, histograms, convolutions, morphological operations, frequency filtering, colouring, resampling, statistics and others. It supports most common raster image formats (PNG, TIFF, JPEG, FITS, OpenEXR), or chain to ImageMagick/GraphicsMagick.
