This directory contains public domain programs distributed as a service by Whiteley Research, Inc. Most of these are covered by the GNU Public License or the GNU Library Public License. These programs are provided "as is" and no guarantees are given or implied as to the fitness of these programs for any particular purpose. No liability will be accepted for any consequence of their use.

These programs can also be accessed via anonymous ftp at ftp.wrcad.com and ftp.srware.com.

Included are:

A free anti-spam filter

A free ic layout editor

A free Verilog simulator

A free HTML browser

Other, more specialized applications

Many of the programs are provided as tar archives which have been compressed with the gzip program. The gzip program, or the GNU tar program used with the z option, is required for decompression. Both are available from prep.ai.mit.edu in pub/gnu.

Windows Note: The programs with distribution files of the form xxx-setup.exe are designed to run on any Win32 platform (95/98/NT/2000/XP). The distributions in the form xxx-ntexe.tar.gz are intended to work on Windows NT/2000/XP, and may not work on Windows 95/98. Original releases of Windows 95 lack the MSVCRT.DLL file needed to run any of these programs. However, installing software such as Internet Explorer will provide this file. It can also be obtained from a friend with a newer Windows system (it lives in the System folder).

GCC-3.X Note:: The present releases should now compile without trouble using gcc-3.x. Previous versions of mozy, vl, and httpget, developed using gcc-2.95.3, were not directly compatible with gcc-3. Since gcc-3 is distributed with Red Hat 8, this was a problem. Thanks to everyone who sent patches, and aplogies for not fixing this sooner.

Links

Below are some links to other public-domain free software which in some cases is needed by or used with the programs listed below, or is deemed interesting or useful for some reason.

The GTK+ widget library
This is a library of graphical user interface components for UNIX/Linux. The library is used with Whiteley Research products.

The Cygwin tools
The cygwin tools are a set of UNIX programs that do an excellent job of providing a UNIX-like environment under Microsoft Windows. The cygwin dynamic link library, the core of the project and used by all of the tools, provides many of the functions of the UNIX kernel. The set includes a complete program development environment similar to that found on a Linux system, which allows many UNIX/Linux applications to port to Windows directly. The disadvantage is legal: programs built in this environment contain copies of the cygwin library, which can not be distributed commercially without paying royalties.

The MINGW tools
The mingw (Minimalist GNU for Windows) project is related to the Cygwin project, but does not use the cygwin kernel. Rather, it uses the native Windows facilities. This means that programs must be developed specifically for Windows, but there is no licensing constraint. It is an excellent choice for developing programs under Windows for those used to the gcc compiler and UNIX tools. With few exceptions, Whiteley Research Windows programs are compiled with mingw.

Distributions

aspam-2.6.tar.gz (107 Kb) HTTP Download FTP Download
This is an email anti-spam filter for use on Unix/Linux machines. Spam messages are extracted from the user's mailbox and placed into a separate spam mailbox. This release includes DNSBL querying and Bayes filtering. Aspam is used for anti-spam duties at Whiteley Research Inc. See http://www.wrcad.com/aspam/ for more information.

bsd-mail.patch (3.7 Kb) HTTP Download FTP Download
This is a patch for the common BSD mail program, which enables automatic saving of deleted messages to a folder. If you've ever lost messages due to deleting the wrong message by mistake, you know why this patch is needed. Requires source code to the mail program, for FreeBSD but should be applicable to others as well. See the patch file header for details.

gtkhtm-1.8.tar.gz (348 Mb) HTTP Download FTP Download
This is an HTML viewer widget for the GTK+ toolkit. It is the successor to gtk-xmhtml, which was previously distributed from this archive. It is self-contained, i.e., gtkhtm does not require GNOME or other libraries, but does benefit from the standard graphics libraries. The distribution provides source code to build the library, and a simple test program. This is intended for experienced programmers.

httpget-2.17.tar.gz (209 Kb) HTTP Download FTP Download
This is a utility and library for retrieving files from the Internet via HTTP and FTP protocols. The distribution consists of source code which will build on UNIX/Linux systems or Windows running cygwin or mingw. Probably requires programming experience to build and use.

induct.tar.gz (22 Kb) HTTP Download FTP Download
This is a 2-D Chang's algorithm evaluator for calculating the inductance of an array of superconductors, written by Jay Fleischman at Berkeley. This is the source code distribution, compiles under Unix/Linux or Windows (mingw).

induct-setup.exe (143 Kb) HTTP Download FTP Download
This is a 2-D Chang's algorithm evaluator for calculating the inductance of an array of superconductors, written by Jay Fleischman at Berkeley. This a self-extracting binary distribution for Windows, also contains the "sline" superconducting microstrip model.

imsave-1.4.tar.gz (10 Kb) HTTP Download FTP Download
