Barcode Writer in Pure Postscript generates all barcode formats entirely within PostScript so that the process of converting the input data into the printed output can be performed by the printer or RIP itself. This is ideal for variable data printing (VDP) and avoids the need to re-implement the barcode generation process whenever your language needs change.

Comptty is used to compare two RTTY streams. It's comparison function uses a linear-programming technique. It computes total number of errors, the character error rate (CER) and the bit error rate (BER). Special attention is given to SHIFT and UNSHIFT to account for an error occurring in that character.

Scatterplot3d is an GNU R package for the visualization of multivariate data in a three dimensional space. Basically scatterplot3d generates a scatter plot in the 3D space using a parallel projection. Higher dimensions (fourth, fifth, etc.) of the data can be visualized to some extent using, e.g. different colors, symbol types or symbol sizes.

Tool that can give numerous reports on memory usage on Linux systems. Unlike existing tools, smem can report proportional set size (PSS), which is a more meaningful representation of the amount of memory used by libraries and applications in a virtual memory system.

This package provides a program designed to test the functionality of a VT100 terminal (or emulator). It also supports analysis of VT220, VT420, and xterm.
