Retired Software Written by John HeidemannThis web page lists software I've written but no longer maintain either because it is "done", transfered to others, superceeded by other work, or no longer useful.
Operating System Modifications
- UCLA Stackable Filing
is the subject of my
My stacking work is available in several forms,
part in 4.4BSD and MacOS-X,
a larger part here,
and the complete distribution for people with a SunOS source license;
details are available.
Since this work has been transfered to others I no longer actively develop it.
- kernel debuggers
is a source-level kernel-debugger for SunOS 4.1 based on GNU gdb
and Sun's kadb. It requires Sun kernel source code to build
and two machines to operate.
Xkdebug is a modification to David Hinds kdebug-1.2 allowing breakpoints and single-stepping in a Linux source-level kernel-debugger.
These debuggers are either for platforms that are no longer interesting (SunOS) or have been superceeded by other kernel debuggers (Linux).
- Linux and FreeBSD configurations
- I maintain some tips
about configuring Linux and FreeBSD
for some of the laptops I've used.
(This page is now elsewhere because it's not really software.)
- Apache Performance Enhancements
As part of my work with ISI's
project we have found some
in http-server performance.
This work has been integrated into Apache for a long, long time now.
The WWW::Search library provides a Perl API to Web search engines
(work done as part of
I no longer maintain WWW::Search. See the README file in a current release in CPAN for information.
- WebStone-1.1 patches
is a useful benchmark.
fixes some portability problems (for SunOS)
and avoids rexec (and the need
to specify a password in the configuration file).
These patches have been superceeded by more recent WebStone releases.
- sawfish extensions
- Finally, an emacs-like window manager... and some extensions.
- A news-to-mail gateway written in Perl.
This works, but sadly, netnews is so 1990's.
- Yet another easily-extensible
Tcl/Tk-based system monitor.
Watch your clock and laptop battery.
I actually do maintain this for me, but there are better tools available for others.
- jogutils with jogscroll
- I added ``jog_scroll'' to
Takaya Kinjo's jogutils support for Sony's jog-dial
on their VAIO laptop hardware.
This probably still works, but there may be better choices now.
Emacs Macro Packages
- Emacs macro packages
- Emacs is my editor-of-choice, and
I've written a couple of packages for it.
provides one-click mouse commands to scroll and copy/move text.
Version 2.21 released.
A version of mouse-extras will be in emacs 19.35.
I no longer maintain this as a separate package since it's now in the standard emacs release.
- crypt+pgp-pub.el (download .el, 111KB) is a version of crypt++ (by Lawrence R. Dodd, Rod Whitby, and Kyle E. Jones) that I've hacked up to support pgp-public-key encryption on files. This code has been subsumed into Karl Berry's updated crypt++.
Games and Amusements
Although all these programs still work, better implementations now exist for Linux/FreeBSD.
is a solitaire card game for X11.
is another solitaire game for X11 modeled after
the game ``Free Space'' distributed with Microsoft Windows NT.
is a Minesweeper implementation for Unix and X11.
While the user interface is not very strong,
xbomb is the only Minesweeper implementation
(that I know of) which allows programmable
solvers to aid the player.
No longer must one do all the boring parts of the maze by hand,
xbomb's solvers do it for you!
- Hyperer is a screen saver that draws n-dimensional rotating hypercubes.
Odds and Ends
- Cluster-based Energy Conservation is follow-on to Geographic Adaptive Fidelity (GAF), a topology control protocol for sensor networks. This work was done by Ya Xu and is described in his paper about CEC. The source code for GAF is in the standard ns distribution (since 2.1b5), but the source code to CEC is only available in the snapshot at this page.
- CRP extensions
- Some extensions for CRP (Dirk Grunwald's conference management package) to support Sensys 2006.
