Biggles is a Python module for creating publication-quality 2D scientific plots. It supports multiple output formats (postscript, x11, png, svg, gif), understands simple TeX, and sports a high-level, elegant interface. It's intended for technical users with sophisticated plotting needs. The goal is to produce the best scriptable plotting program.

GRPN is a RPN calculator for the X Window system built using the GIMP Toolkit (GTK). GRPN works with real numbers, complex numbers, matrices, and complex matrices. Numbers can be displayed in 4 different radix modes, and complex numbers can be displayed in either Cartesian or polar form.

This is Math::BigInt::Pari, a plugin module for Math::BigInt that replaces Math::BigInt's core math routines with Math::Pari routines. This package contains a replacement (drop-in) module for Math::BigInt's core, Math::BigInt::Calc.pm. It needs the new versions of Math::BigInt and Math::BigFloat as they are from Perl 5.7.x onwards.

This package provides cubic spline interpolation of numeric data. The data is passed as references to two arrays containing the x and y ordinates. It may be used as an exporter of the numerical functions or, more easily as a class module.

Math::Symbolic is intended to offer symbolic calculation capabilities to the Perl programmer without using external (and commercial) libraries and/or applications. Possibly the most convenient way of constructing Math::Symbolic trees is using the builtin parser to generate trees from expressions such as '2 * x^5'. You may use the Math::Symbolic->parse_from_string() class method for this.

Display runs a specified command over and over, printing the output through curses(3X). The command can be compound and the delay between executions is settable on the command line. The output from the command had better fit on a single screen, of course. This can conflict with the application of the same name from the graphics/ImageMagick port/package.

BB is an high quality audio-visual demonstration for your text terminal. It is portable demo, so you can run it on plenty of operating systems and DOS. Supports: DOS (VGA + MDA), stdio, curses, slang, X11, gpm, linux-console Sound: OSS, Sun audio, SGI, DEC Aplha, AIX, HP-UX, DOS (GUS CLASSIC, GUS CLASSIC, GUS MAX, GUS ACE, GUS PNP, SB, ESS, PC-buzzer

This distribution contains a module I18N::Charset which maps Character Set names to the names officially registered with IANA. For example, 'Shift_JIS' is the official name of 'x-sjis'. It also maps character set names to Unicode::Map8 conversion scheme names (if Unicode::Map8 is installed). For example, the Unicode::Map8 scheme name for 'windows-1251' is 'cp1251'.

tkRunIt is a run dialog box for X which allows you to execute commandline without using an xterm. tkRunIt was inspired by Xrun but is designed to be completely navigable from the keyboard and to allow extreme customizablility as I often find that personal workspace tools/shortcuts are seldom workflow compatible across users.

gstreamer-vaapi is a collection of GStreamer plugins and helper libraries that allow hardware accelerated video decoding through VA-API. Depending on the underlying hardware, the following video decoders are supported: JPEG, MPEG-2, MPEG-4:2, H.264 and VC-1. Renderers are available for X11, GLX, Wayland and raw DRM for headless pipelines.
