libRational is a C++ class library for rational arithmetic.
Installation:
The `configure shell script attempts to guess correct values for various system-dependent variables used during compilation.
It uses those values to create a `Makefile in each directory of the package. It may also create one or more `.h files containing system-dependent definitions.
Finally, it creates a shell script `config.status that you can run in the future to recreate the current configuration, and a file `config.log containing compiler output (useful mainly for debugging `configure).
It can also use an optional file (typically called `config.cache and enabled with `--cache-file=config.cache or simply `-C) that saves the results of its tests to speed up reconfiguring. (Caching is disabled by default to prevent problems with accidental use of stale cache files.)
If you need to do unusual things to compile the package, please try to figure out how `configure could check whether to do them, and mail diffs or instructions to the address given in the `README so they can be considered for the next release.
If you are using the cache, and at some point `config.cache contains results you dont want to keep, you may remove or edit it.
The file `configure.ac (or `configure.in) is used to create `configure by a program called `autoconf. You only need `configure.ac if you want to change it or regenerate `configure using a newer version of `autoconf.
The simplest way to compile this package is:
1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system.
If youre using `csh on an old version of System V, you might need to type `sh ./configure instead to prevent `csh from trying to execute `configure itself.
Running `configure takes awhile. While running, it prints some messages telling which features it is checking for.
2. Type `make to compile the package.
3. Optionally, type `make check to run any self-tests that come with the package.
4. Type `make install to install the programs and any data files and documentation.
5. You can remove the program binaries and object files from the source code directory by typing `make clean. To also remove the files that `configure created (so you can compile the package for a different kind of computer), type `make distclean.
There is also a `make maintainer-clean target, but that is intended mainly for the packages developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution.
Enhancements:
- src/BigInt.hh: removed #ifdef structures
- src/BigInt.icc: assignation BigInt = MpIeee moved to source file
- src/TmpBigInt.hh: moved constructor from MpIeee to source file
- src/b_BigInt_MpIeee.cpp: moved constructor/assign MpIeee to this file
- src/r_toMpIeee.cpp: wrong FPParams constructor was called

wmappl is a simple scrolling application launcher for the WindowMaker dock. It is loosely based off of WMButton by Edward Flora.
Given a list of programs and icons, wmappl displays up to six icons at a time. Scroll buttons or the mouse scroll wheel may be used to cycle through additional programs.

SBaGen generates sounds that give an altered state of consciousness. The theory behind binaural beats is that if you apply slightly different frequency sine waves to each ear, a beating affect is created in the brain itself, due to the brains internal wiring.
If, in the presence of these tones, you relax and let your mind go, your mind will naturally synchronize with the beat frequency. In this way it is possible to tune the frequency of your brain waves to particular frequencies that you have selected, using of the four bands: Delta: deep sleep, Theta: dreaming and intuitive stuff, Alpha: awake, focussed inside, and Beta: awake, focussed outside.
It is also possible to produce mixtures of brain waves of different frequencies by mixing binaural tones, and in this way, with practice and experimentation, it is reportedly possible to achieve rather unusual states, such as out-of-body stuff, and more. See the books by Ken Eagle Feather, and the Monroe Institute site for more details. The Monroe Institute have apparently put 40 years of research into these techniques.
Centerpointe have also done a great deal of research into binaural beats, concentrating more on improving overall well-being and holistic functioning rather than reaching unusual states, and I recommend reading some of the articles on their site (look under "Site Map", for example their Special Report: "How The Holosync Technology Works" and their FAQ).
I should add that I have only read about the more advanced and unusual uses (OOBEs and so on). My own experiences have not reached quite that far, but still I feel that I have benefitted immensely from using these techniques over the last few years: from simply getting my head clear in confusing moments, to the energy boosts that come at times, to more general emotional clearing, and occasional very intense dreams (although not quite lucid).
So, SBAGEN is my utility, released as free software (under the GNU General Public Licence) for Linux, Windows, DOS and Mac OS X, that generates binaural tones in real-time according to a 24-hour programmed sequence read from a file. It can also be used to play a sequence on demand, rather than according to the clock, or to write a WAV file for playing later. Pink noise, MP3 and Ogg files (since version 1.2.0) may also be mixed with the binaural beats to provide background sounds. (Two files of randomly-looping river sounds are provided from version 1.4.0 onwards). This tool is ideal for anyone who wishes to experiment with these techniques and do research into this for themselves. (For those who would rather pay for a pre-packaged programme with support, I recommend taking a look at the Centerpointe site -- and see my disclaimer)
My original idea was to use this utility to play a programme of different tones throughout the night, hoping to improve dreaming and dream-recall, and then to bring myself up into Alpha rhythms to (hopefully) make a good start to the day. I am now using it more for shorter focussed sessions of about an hour, both during daytime and at night. However, other people have used this software in many different ways. For example, one person suffering constant pain from historical injuries appreciated the way that he could tune the frequencies very accurately to his needs to help him sleep better at night. Other more unusual uses have included: mixing the sounds in as part of musical compositions, and generating ambient sounds during live DJ sets or trance music.
Enhancements:
- Fixed problem when playing 7+ hour sequences with -SE or -L
- Warns properly if the WAV file limit of ~7 hours is exceeded, and truncates

wmnetload is a network interface monitor dockapp for Window Maker. wmnetload is designed to fit well with dockapps like wmcpuload and wmmemmon.

It tracks whether the interface is functioning and displays current network interface throughput, along with an auto-scaling graph of recent network activity (the graph separates upstream and downstream traffic load cleanly without resorting to colors).

Configuring the Look

Since one of the main goals of wmnetload is to match the look-and-feel of wmcpuload, and since the look of wmcpuload was changed as of version 0.9, the look of wmnetload has also been revised. However, those who prefer the "classic" wmnetload look (or who are still using older versions of wmcpuload) can compile wmnetload to present the original look by passing --with-classic-look to `configure.

Interface Cycling

Although wmnetload can monitor only a single interface at a time, the interface being monitored can be selected by using mouse buton 3 to cycle through each of the available interfaces. Note that with the classic look, wmnetload does not display the name of the interface, which makes interface cycling hard to use without getting confused.

Alarm Mode

Like wmcpuload, wmnetload allows you to set an alarm value (in kbits/sec) that causes the display backlight to be turned on whenever it is exceeded. This is chiefly useful for alerting you to unusual or aberrant network behavior.

wmUpMon is a dockapp that displays your system uptime in realtime.

Logsurfer project was designed to monitor any text-based logfiles on your system in realtime. The large amount of loginformation collected (like all messages handled by the syslog-daemon or logfiles from your information services FTP, WWW etc.) makes it nearly impossible to check your logs manually to find any unusual activity.
You need a program to do this for you. If you dont want to use a script that checks your logs in certain time intervals (like once a day) then you might be interested in the programs like swatch or logsurfer.
Main features:
- Works on any textfile (or text from standard input)
- Matching of lines is done by two regular expression (logline must match the first expression but must not match the optional second regular expression). So you are able to specify exceptions.
- Uses contexts (collection of messages) instead single lines
- Flexible but easy configuration
- Timeouts and resource limits included
- Handles "shifting" of logfiles (just send a -HUP signal to close and reopen the logfile after you have moved the old one to another place and created a new one)
- Dynamic rules can change the actions associated with logmessages (something might happen that makes you interested in messages you would usually drop)
- Multiple reactions on one logline possible
- Portable written C-code (uses GNU regex library and autoconfigure)
