Free negative ions software for linux

DemoWave is a Web application for conducting referendums that:

allows anyone to propose a new referendum
minimizes the negative effects of people "spamming" the system with bogus referendums
makes referendums where people disagree a lot take longer to go through.

In addition, it can manage a set of laws and referendums on changes to those laws.

DemoWave is intended for democratic organizations that need to decrease the bureaucratic load and increase the participation of their members in the decision-making process.

Nwfiir audio tools is a free suite of console programs for your Unix machine (Linux in particular) to process high resolution digital audio. The suites core program is nwfiir, which is a real-time digital equaliser. The name is a combination of the abbrevations FIR, IIR, WFIR and WIIR, that is four types of filters, Finite Impulse Response, Infinite Impulse Response and their warped counterparts. Currently only FIR and WFIR have been implemented in the application
The goal of room equalisation is to have a desired power response in the listening position. The desired response is most often the flat one, that is when all frequencies in the audible range, from 20 - 20000 Hz, are equally amplified. You may own very expensive speakers and amplifiers and so on, that will produce a flat power response, but only if it is placed in an anechoic lab environment. The room have a profound impact on the sound.
To minimise the problems, one can measure the power response in the listening position with a microphone, and with help of that put in a precisely tuned equaliser that minimises the rooms negative impact on the sound. Commercial systems exist for this (Roister, Tact Audio), however they are still very, very expensive. The software presented here is a a full room equalisation system, apart from the hardware which you may well own already anyway.
Enhancements:
- New component: fird, a FIR filter designer, however with no psycho-acoustic stuff yet.
- A quick hack: fconv, a fast convolver, ugly code lack of features and so on, but can be used to demonstrate how much faster fast convolution is than convolution in the time domain (which nwfiir does).
- Fixed some Makefile stuff.

brainwash project is an open source interpreter for the Brainfuck programming language, written in ANSI C.
Implementation-specific details:
- The array has no bounds; this makes the pointer able to move towards both left and right "infinitely".
- Since each cell holds a signed integer value, cell values can be negative.
- Cell values are initialized to 0 (zero).
- A cell will assume its minimum/maximum value if it is already at its maximum/minimum value and a + / - command is executed respectively.
- Cell values are left intact when executing a , command after the end of input.
- Characters other than the eight Brainfuck commands are considered to be comments and are thus ignored. This, with the exception of ! and # that sometimes act as commands and other times dont (comments).
- When both the program code and its input are read from stdin, ! is (a command) used to separate them.
- When the -d option is used, # is (a command) used to print, to stderr, a memory snapshot of the surrounding cells (useful for debugging).
brainwash is distributed under the terms of the 2-clause revised BSD license which is available in its LICENSE file.
Installation
For gzip:
$ tar -xzvf brainwash-0.2.tar.gz
For bzip2:
$ tar -xjvf brainwash-0.2.tar.bz2
Then:
$ cd brainwash-0.2/
$ gcc brainwash.c -o brainwash
This will create the brainwash binary under the current working directory.
Usage
By invoking brainwash with the -h option, the following help message is printed:
$ ./brainwash -h
brainwash 0.2 (2005-02-05)
Usage: ./brainwash [-t] [-d width] [-i file] [-o file] [file | -]
./brainwash -h
./brainwash -V
-t Time interpretation.
-d width Print the memory snapshot of the width - 1 surrounding cells upon #.
-i file Read the input from file.
-o file Write the output to file.
file Read the program from file.
- Read the program from standard input (default).
-h Print this help message and exit.
-V Print version information and exit.
Enhancements:
- Licensed under the MIT license.
- Standardized the use of temporary files.
- Made unsigned character cells possible by issuing `make char` instead of
- `make` during installation.
- Removed the -t option (not accurate).
- Made the argument of the -d option to default to 11 or less.
- Made the array finite at the left.
- Made the program to ignore a possible shebang line to allow executable
- Brainfuck programs.
- Implemented optimization (suggested by Jon Ripley) through the -O option.

Workrave project can assists you in the recovery and prevention of Repetitive Strain Injury (RSI).
The program frequently alerts you to take micro-pauses, rest breaks and restricts you to your daily limit.
Please refer to the feature comparison for a complete list of features, and how the program performs with respect to other programs on the market. The program runs on GNU/Linux and Microsoft Windows.
Main features:
- Distributed: The program runs distributed on one or more PCs. All connected PCs share the same timing information. When the user switches computers, he still will be asked to pause on time.
- Server data collect: All programs in a network report user data detailing break information, mouse and keyboard usage to a central server. The data stored on this server may be analysed to detect user behaviour and, for example, take proactive measures.
- Applet: The program is able to show status information in an applet that is embeddable in the desktop panel or taskbar.
Enhancements:
- Eraldo Girardi translated Workrave into Italian.
- Better support for vertical applets on Unix.
- Tao WEI translated Workrave into simplified Chinese.
- Peter Tuharsky translated Workrave into Slovak.
- Prokopis Prokopidis translated Workrave into Greek.
- The status window used to appear empty, only to be resized and filled with the timers shortly thereafter. Now it appears right away in the proper size.
- The operation mode (normal/quiet/suspended) now persists across Workrave sessions.
- Enver Altin translated Workrave into Turkish.
- Masanobu Yokota translated Workrave into Japanese.
- Ivan Dimov translated Workrave into Bulgarian.
- ORY Mate translated Workrave into Hungarian.
- Fixed KDE sound events (Phuah Yee Keat)
- Fixed Gnome sound events
- Fixed negative mouse usage when date is changed.
- Fixed text color on Gnome themes with dark backgrounds (i.e. high contrast inverse)
- Gnome applets now support transparency.
- The datadir configuration option in workrave.ini can now be a relative path: [general] datadir=.Data This will store all Workrave data in the Data directory below the Workrave root directory. (Note the double backslash)
- Daily limit now properly resets when hibernated.

Apache Solr is a high performace search server based on Lucene, with XML/HTTP and JSON APIs, hit highlighting, faceted search, caching, replication, and a Web administration interface.
The project is currently under incubation at the Apache Software Foundation.
Instructions for Building Apache Solr
1. Download the J2SE 5.0 JDK (Java Development Kit) or later from http://java.sun.com. You will need the JDK installed, and the %JAVA_HOME%bin directory included on your command path. To test this, issue a "java -version" command from your shell and verify that the Java version is 5.0 or later.
2. Download the Apache Ant binary distribution from http://ant.apache.org. You will need Ant installed and the %ANT_HOME%bin directory included on your command path. To test this, issue a "ant -version" command from your shell and verify that Ant is available.
3. Download the Apache Solr source distribution, linked from the above incubator web site. Expand the distribution to a folder of your choice, e.g. c:solr.
4. Navigate to that folder and issue an "ant" command to see the available options for building, testing, and packaging solr.
Enhancements:
- This is the first release since graduating from the Apache Incubator.
- Some of the new features include CSV/delimited-text data loading, time based autocommit, faster faceting, negative filters, a spell-check handler, sounds-like word filters, regex text filters, and more flexible plugins.

xtermcontrol enables dynamic control of XFree86 xterm properties. xtermcontrol project makes it easy to change colors, titles, fonts, and the geometry of a running xterm, as well as to report the current settings of the properties.
Window manipulations such as (de)iconify, raise and lower, maximize and restore, and reset are also supported. It also lets advanced users issue any xterm control sequence.
Options:
--fg=COLOR
Set foreground color to COLOR.
--bg=COLOR
Set background color to COLOR.
--colorN=COLOR
Set Nth [0-15] color to COLOR.
--highlight=COLOR
Set highlight color to COLOR.
--cursor=COLOR
Set cursor color to COLOR.
--mouse-fg=COLOR
Set mouse pointer foreground color to COLOR.
--mouse-fg=COLOR
Set mouse pointer background color to COLOR.
--font=FONT
Set font name to FONT. Alternatively it is possible to specify a fontmenu index as #[0-6] or navigate the fontmenu by relative sizes as #+N or #-N, where N is an optional integer.
--title=STRING
Set window title. Note that mechanisms like the Bash PROMPT_COMMAND may overwrite the title. Se also How to change the title of an xterm.
--geometry=WIDTHxHEIGHT+XOFF+YOFF
Set size and/or position. Through its control sequences the xterm only recognize positive XOFF and YOFF offsets, which are pixels relative to the upper left hand corner of the display. xtermcontrol is therefore unable to handle negative offsets as described in the X Geometry Specifications and therefore truncates negative values to zero.
--get-fg
Report foreground color.
--get-bg
Report background color.
--get-colorN
Report Nth [0-15] color.
--get-highlight
Report highlight color.
--get-cursor
Report cursor color.
--get-mouse-fg
Report mouse pointer foreground color.
--get-mouse-bg
Report mouse pointer background color.
--get-font
Report font.
--get-title
Report window title.
--get-geometry
Report size and position. The size of the text area is reported in characters and the position is reported in pixels relative to the upper left hand corner of the display.
--maximize
Maximize window.
--restore
Restore maximized window.
--iconify
Iconify window.
--de-iconify
De-iconify window.
--raise
Raise window.
--lower
Lower window.
--reset
Full reset.
--raw=CTLSEQS
Issue the raw control sequences CTLSEQS.
--file=FILE
Force xtermcontrol to read configurations from FILE instead of the standard personal initialization file ~/.xtermcontrol.
--force, -f
Skip TERM environment variable check.
--verbose, -v
Print verbose reports.
--help, -h
Print help and exit.
--version
Print the version number and exit.
Enhancements:
- src/configuration.c: Fix regexp, so the #rrggbb way to specify a color works in configuration file. Reported by Olle Mulmo.
- doc/xtermcontrol.roff: add BUGS section describing how install needs to setuid root on some broken systems.

retty project is a utlity that can attach to processes running on another terminal. This is useful, for example, when you run an application locally and then decide you want to use that running application from some remote location.
You can run retty on it, do your work, and detach application back again. Its advantage over screen is that you dont have to run the processes on retty in advance.
Bugs:
- Attaching less doesnt work, we have no idea why yet
- The new terminal does not become the new controlling terminal for the application (this seems to be unfixable without messing with the kernel, unfortunately) - that has all sorts of negative consequences, most importantly: /dev/tty is not the right terminal, leading many applications (e.g. mutt) to misguess window size; pressing Ctrl-C does not deliver a signal to the application, so you cant break it this way (send SIGINT manually)
- You can attach only a single process, so if you want to resume editing a mail in mutt, first you need to attach the editor, then when you are finished quit it and attach mutt
