tblutils is a collection of several utilities for working with tabular text files: data written in plain text, with one row per line and columns separated by a common character (usually TAB or semicolon). It complements the usual Unix tools like cut and paste by providing enhanced versions that support column labels through-out, so that you can extract columns by name (tblcut), filter data using a mathematical expression (tblfilter), re-order columns without caring about the column index (tblcsort), join multiple files on a common index without having to pre-sort them (tblmerge), and much more.
Brace is a dialect of C that looks like Python. It has coroutines, hygenic macros, header generation, and libraries with graphics and sound. It is meant to be good for beginners, kids, and experts. Brace is translated to C, then compiled, with #! support and cached executables. It is fairly portable, and runs on GNU/Linux, Unix, and Windows with MinGW. It should also run on Mac OS X. It comes with a lot of demo programs, many with animated graphics.
