Free guarantees software for linux

Alert Manager was created to run an alert command, monitor the status of that commands output, and guarantee that if something goes wrong it wont go unnoticed.
Alert Manager has been successfully deployed in several fortune 500 companies providing guaranteed alert delivery and command execution.
It has a very flexable configuration file that allows creation of "alert chains" - chains of commands, each with their own fallback command, failure command, timeout, retry counter, and other advanced options.
It has a method for passing messages from the command line into the various commands defined in the configuration file
Main features:
- Runs any system command (defined in configuration file) and has several methods for verifying that it executed successfully.
- Logs all activity to a file.
- Has a method to prevent infinite loops of failing commands.
- Supports user definable variables in the configuration file that can be used later in that file.
- Script returns error status to the system when an error occurs and logs a detailed message.
- Verbose error messages to STDOUT if something goes wrong.
- Multiple debugging levels.
Enhancements:
- Fixed a bug in configuration file parsing that would cause alertManager to process some commented lines when it should have ignored those lines.
- Add support for passing the "message" in via STDIN. Just use a "-m stdin" and pipe some text to alertManager.
- Set SIGCHLD to IGNORE so children can exit on their own without waiting for the parent to reap them or exit.

- Archives indicators : Areca computes a lot of indicators for you, which will help you in the everyday management of your archives.

renamepics project uses the exiftags program to rename all JPEG files within a directory to the date and time they were taken using EXIF information.
For example a file named Sally1-birthday.jpg would be renamed something like 20051011-141023.jpg
This keeps all file names unique (provided you arent taking more than 1 picture per second), and lets you tell when the picture was taken with a glance.
renamepics should be considered beta software at best, and there is no guarantee, explicit or implied.
Use at your own risk.
It is working great for me, but if it chews up all your precious pictures and you never see them again, I dont want to hear about it.
Enhancements:
- This release makes exif the default program to extract exif data instead of exiftags, as it seems to run a bit cleaner.
- exiftags can still be used by uncommenting in the script.

Finance::Quote::ASX is a Perl module that can obtain quotes from the Australian Stock Exchange.

SYNOPSIS

use Finance::Quote;

$q = Finance::Quote->new;

%stockinfo = $q->fetch("asx","BHP"); # Only query ASX.
%stockinfo = $q->fetch("australia","BHP"); # Failover to other sources OK.

This module obtains information from the Australian Stock Exchange http://www.asx.com.au/. All Australian stocks and indicies are available. Indexes start with the letter X. For example, the All Ordinaries is "XAO".

This module is loaded by default on a Finance::Quote object. Its also possible to load it explicity by placing "ASX" in the argument list to Finance::Quote->new().
This module provides both the "asx" and "australia" fetch methods. Please use the "australia" fetch method if you wish to have failover with other sources for Australian stocks (such as Yahoo). Using the "asx" method will guarantee that your information only comes from the Australian Stock Exchange.

Information returned by this module is governed by the Australian Stock Exchanges terms and conditions.

Realtime Application Interface project allows applications with strict timing constraints to be run on Linux.

- Context switching between hard and soft real-time, handling of TSC errors, and POSIX compatibility have been improved.
- There are numerous minor bugfixes.

Gnaural is a multi-platform programmable binaural-beat generator, implementing the principles described in October 1973 Scientific American, Gerald Oster, "Auditory Beats in the Brain."

There has been considerable research done on the subject since that publication, and Gnaurals Windows-based predecessor, WinAural, has been used as the audio stimulus in at least one published study, "The Induced Rhythmic Oscillations of Neural Activity in the Human Brain", D. Cvetkovic, D. Djuwari, I. Cosic (Australia), from Proceeding (417) Biomedical Engineering - 2004.

The central finding of Osters article: brain activity can be entrained to the auditory beat frequencies created when each ear is presented simultaneously with tones of slightly offset in frequency. My interest has been exploring how this effect (known as "frequency following response" or "brainwave entrainment") can be used to explore mental states, ranging from profoundly meditative to highly alert.

What are auditory binaural beats?

In 1839, German experimenter Heinrich Wilhelm Dove discovered that playing two tones simultaneously, one in to each ear, induced the perception of a "beat frequency" when the tones were of slightly differing frequency (generally less than 100 Hz apart).

While an acoustic mixing of the two tones will also produce a beat frequency, what is notable about auditory binaural beats is that there is no acoustic mixing of the tones: the beats exist solely within the auditory system. Some researchers believe that they are an artifact of the "neural wiring" used to spatially determine the origins of sounds in our environment.

Gerald Osters breakthrough in 1973 was to observe that the neural processing associated with binaural beats can induce an overall entrainment of brainwave activity (essentially, an oscillation between the two hemispheres in sync with the beat frequency). The neurology of this phenomenon is, according to Oster, tied to the contralateral integration of auditory input taking place in the superior olivary nucleus in the brainstem.

My main interest in the principle has been the possibility that brainwave entrainment can be used to target specific mental states. Gnaural has a long lineage, starting with a DOS program in the mid 1990s, progressing to WinAural for Windows and (in the hope a making a cross-platform solution) BrainJav for Java, and finally the truly cross-platform solution in Gnaural. In over a decade of experience with the technique, I have mainly found it useful for slowing-down brain activity. In that capacity, it has served me in areas ranging from stress reduction, sleep make-up, and particularly as a sort of "poor mans meditation", requiring almost no effort to achieve states of mind that I usually have found rather hard to achieve with real meditation.

But these are strictly my observations, and I make no guarantees about what the technique can do for anyone else. Some of the more unusual applications Ive heard about for my software include sustaining a heightened mental focus for online tournament gaming, and enhancing flotation-tank and related sensory deprivation environments. Many people also apparently use the technique to study more effectively.

One of the stranger facts regarding binaural beats is their seeming ability to be equally-at-home in the laboratory setting as in "grass roots" contexts (such as alternative medicine and the New Age phenomenon). That there is a grass-roots enthusiasm (easily demonstrated by googling binaural beats) is probably related to the sense of promise inherent in an easy-to-implement technique offering the possibility of direct influence of brain behavior. But from a scientific standpoint, there is a big gap between claims (of what binaural beats can do) and corroboration (by scientific method), which has led to a sense in many that the actual subject of binaural beats is "controversial." But this is an irrational response, given that the actual scientific/laboratory basis of binaural beats has remained an established part of the scientific literature for over 30 years.

One of my goals in writing Gnaural was to implement the binaural beat principle within the bounds of my understanding of the established scientific facts regarding the subject. To some extent, this has meant leaving-out many of the "bells and whistles" prevailent in other implementations. That my software has been used for at least one published "hard-science" study suggests that it has been somewhat successful. However, I also hope that Gnaural proves useful for people who wish to explore subjective areas unfettered by scientific rigor. In a subject dealing with matters of the mind, I see both sides -- "grass-roots empiricism" and "scientific empiricism" -- as being complementary halves of a complete investigation of the possibilities, and ultimately, Id hope to see the two sides of our culture be catalysts for each other, rather than inhibited by a mutual antagonism.
