Open Dylan compiles to native code and has a full-featured IDE including an incremental development mode, browsing of runtime objects, remote debugging, etc. Open Dylan currently only runs on the x86 platform and the IDE does not yet run on the Linux version. Open Dylan is in many ways a mature implementation. If you are new to the language, choose Open Dylan if you can.

Fancy biff program under X11 environment. Hbiff is a replacement for xbiff that flashes when new mail arrives like the traditional xbiff. In addition, if you click on the hbiff icon, a window will popup showing the mail headers. This makes hbiff better than xlbiff where privacy is an issue since the headers are only displayed when you request. hbiff can also run the MUA for you.

Elmo (ELectronic Mail Operator) is an ncurses-based program for receiving, filtering, reading, composing, and sending mail from a character terminal. It speaks POP3 and SMTP and can work with maildir or Berkeley-formatted mailboxes. This version is a development version, but is rather stable, and is known to work better than the stable version on FreeBSD 4.x. Before running elmo, users should run elmoconf.pl to generate an ~/.elmorc file.

clRNG a library for uniform random number generation in OpenCL. Streams of random numbers act as virtual random number generators. They can be created on the host computer in unlimited numbers, and then used either on the host or on computing devices by work items to generate random numbers. Each stream also has equally-spaced substreams, which are occasionally useful. The API is currently implemented for four different RNGs, namely the MRG31k3p, MRG32k3a, LFSR113 and Philox-4x32-10 generators.

This module was adapted from Math::Vector. It uses most of the same algorithms, and currently preserves the same names as the original functions, though some aliases have been added to make the interface more natural. The "object" for the object oriented calling style is a blessed array reference which contains a vector of the form [x,y,z]. Methods will typically return a list.

The Statistics::LineFit module does weighted or unweighted least-squares line fitting to two-dimensional data (y = a + b * x). (This is also called linear regression.) In addition to the slope and y-intercept, the module can return the square of the correlation coefficient (R squared), the Durbin-Watson statistic, the mean squared error, sigma, the t statistics, the variance of the estimates of the slope and y-intercept, the predicted y values and the residuals of the y values.

The Math::VectorReal package defines a 3D mathematical "vector", in a way that is compatible with the previous CPAN module Math::MatrixReal. However it provides a more vector oriented set of mathematical functions and overload operators, to the MatrixReal package. For example the normal perl string functions "x" and "." have been overloaded to allow vector cross and dot product operations. Vector math formula thus looks like vector math formula in perl programs using this package.

Graphillion is a Python software package on search, optimization, and enumeration for a graphset, or a set of graphs. - Lightweight data structures for handling x-illions of graphs - Search, optimization, and enumerate large and complex graph sets - Efficient implementation extending Python with C/C++ - Working with existing graph tools like NetworkX - Open source MIT license - Well tested: more than 600 unit tests - Fast prototyping, easy to teach, and multi-platform

Triangle generates exact Delaunay triangulations, constrained Delaunay triangulations, Voronoi diagrams, and quality conforming Delaunay triangulations. The latter can be generated with no small angles, and are thus suitable for finite element analysis. Show Me graphically displays (using X) the contents of geometric files, especially those generated by Triangle, my two-dimensional quality mesh generator and Delaunay triangulator. Show Me can also write PostScript images to files.

gtkfind is the program to use when you don't want to have to remember all the options to find(1). It is a graphical program that allows you to search for files and (optionally) perform operations on them. You can search for files by using wildcards, by matching file types and/or permissions, etc. gtkfind requires X and the GTK+ toolkit. It is still under development, but has reached a stage where it is actually useful.
