Real-Time Proactive Secret Sharing Library is an implementation of the Shamirs secret sharing scheme and Herzbergs proactive secret sharing algorithm.

Real-Time Proactive Secret Sharing Library targets the RTAI OS. It includes a port of GNU GMP to RTAI, which is used for multiple precision arithmetic operations.

to run the rt-pss

./start_pss ID (*) ID should be between 0 and PSSW_NUMBER_OF_MACHINES-1(this constant is defined in src/share_app_pssw.h)
(*) each local RT-PSS should be executed with a
different ID starting with 0
(*) you must have superuser privilegies to do that.

to stop the rt-pss


./stop_pss (*) be sure that no applications that uses the RT-PSS are
running.
(*) you must have superuser privilegies to do that.

developing RT-PSS Apps

There is a demo application available in the directory: examples/GetShare. The RT-PSS API can be consulted in the file README.API

Slicetime is a program that helps you track time you spend on projects. Slicetime is designed to make it easy to switch between different projects, the main window is in the shape of vertical sidebar that makes it convenient to keep it always visible on the side of the screen. In short, continuous tracking of time taken on projects is made as effortless as possible.
The purpose of the program is to make you aware of which tasks take more time, and which take less; it can also be used to keep track and charge time if youre working for someone on hourly basis. The advantage of the program is that it lets you switch back and forth very easily, letting you keep a very accurate account of how much a task took even if you have to stop it frequently and work on something else.
The results can be very surprising, something may feel like it took only a few minutes whereas it took almost an hour in real time; the reverse is sometimes true although not as often.
Slicetime main window is a vertical bar with a row of buttons, each button representing a project. When the button is pressed in, the project is active, the rest of projects are inactive. Each project button shows the time taken on the project today. At 12 oclock the daily time is reset and new days count is started.
Time is kept for current day, week, month and total. Example: I may have a slicetime project that has 3:59 time today, 8:00 this week (including today), 17:00 this month (including this week) and 125:00 total time, which may have been accumulated over years.
Slicetime makes it easy to change project time for current day if you forgot to check in or check out. Menu command (add or subtract project time) will add or subtract the time for today. Another command will set all times for total, month, week and day.
Slicetime as of now has two report options, it can report by time taken for each project on a daily, weekly, montly and total basis and the same by percentage. For example, it will show that today project A was 60%, project B - 30% and C - 10%, and will do the same for current week, month and total.
Note that Slicetime does not keep separate time accounting from previous week, month, day, etc. It will not tell you that you spend 5 hours last saturday. It will only tell you total time, time taken on current month, week and day; but it makes perfect sense to keep this data as well, and I will almost certainly add it.
Functionality:
- Add project
- Remove project (deletes all data and button, irrecoverable, use sparingly!)
- Report by time
- Report by percentage
- Set project time
- Add or subtract project time
Version restrictions:
- Number of project buttons is effectively limited by vertical size of screen. On a common 1024 res, you can fit in around 42 projects, which should be enough for anyone, but I will add an option of hiding projects from main window if requested.
- Latest version not tested in Unix, but will most likely work. I will test it soon & fix if needed.
- Could keep time for each past day, week, month, year. Most likely will be added eventually.
Enhancements:
- Several bugs were fixed.
- The interface was changed to be more user friendly.
- Autosave functionality was added to make up for some stability problems on WinXP.

Rails Real-Time Form Validation Plug-In uses AJAX to validate form data against a model in real-time. AJAX requests are made as the user is filling in form fields.
The form data is then validated against a model on the server-side. RTV then responds with javascript that dynamically updates the HTML document. This enables you to mark form fields as valid/invalid using CSS.
The download package now includes a sample rails application. It does not need a database to run, thanks to this. Simply execute ./script/server from the rtv_sample_app directory and point your bwoser to http://localhost:3000.
Usage:
Download and extract the contents of the_plugin directory to your vendor/plugins directory. Please the the rtv_sample_app for more details.
In your controller:
include UIEnhancements::RealtimeValidation
helper :RealtimeValidation
realtime_validation_for(:the_form_id, :the_model)
In your view, after a form:
In your CSS (example):
.fieldWithoutErrors,
.fieldWithErrors
{
outline-width: 1px;
outline-color: white;
outline-style: solid;
/* !!HACK!! IE will not use this because it does not understand !important. Border is not needed for firefox, so make it 0px!*/
border-width: 0px !important;
/*for IE!*/
border-width: 1px;
border-color: white;
border-style: solid;
}
.fieldWithErrors
{
background: pink;
background-color:pink;
outline-color: red;
/*for IE!*/
border-color: red;
}
/* Browser support may be limited here...*/
.fieldWithErrors input,
.fieldWithErrors select,
.fieldWithErrors textarea
{
background: pink;
background-color: pink;
}
Known to work with:
- Rails 1.1.6
- FireFox 2
Enhancements:
- This release adds a sample application, some code cleanup and minor bugfixes, and some changes to the sample CSS.

Cascade Historian software is an event driven data storage program used to maintain persistent time-sequence data sets derived from process data.

Features and Benefits

In addition to providing storage the Historian also offers a historical query facility suitable for generating graphs and tabular output for export to other analysis programs. Other programs can also send data to the Cascade Historian by linking the API library and making the appropriate function calls.

The data storage mechanism within the Cascade Historian will maintain any number of simultaneous time histories, one for each configured process point.

The data for each point is maintained in one or more files, allowing for removal of stale data or offline archival of old data. These files are either numbered in increasing numerical order, or dated. When using dated files, the Cascade Historian automatically begins logging to a new file at midnight.

Data logging by event

The Cascade Historian records data by event. If no data change event occurs for a point, no data is written to disk. This saves disk space when the process point is idle, and captures even very short duration events when the point is changing. This is both more efficient and more accurate than a sampling historian. It is possible to place both a time and value deadband on each point to reduce storage for points whose values are constantly changing by insignificant amounts. The Cascade Historian will not reorder out of sequence data.

Data is stored on disk in fixed length binary records to minimize disk space, with a time resolution of nanoseconds. These files can be easily read by any custom program as well as by the Cascade Historian.

Any process may request data from the Cascade Historian. The Cascade Historian maintains a configurable in-memory cache for each point being recorded so that queries of recent data will not require disk access. If the request cannot be satisfied from the in-memory cache, then the disk files related to the point will be consulted for the data to satisfy the request. The requests can take one of the following forms:

Raw Data - Simply returns all recorded events for the data point, reported vs. time.
Periodic Data - Performs linear interpolation on the data to produce a data set at an even time interval. This produces the same result that a sampling historian would produce.
Relative Interpolation - Performs interpolation of one data point against another to produce a Y vs. X data set. Interpolation is performed on Y to produce (X,Y) pairs at the times of known values of X.
Periodic Relative Interpolation - Performs interpolation of one data point against another to produce a Y vs. X data set. Interpolation is performed on both X and Y to produce (X,Y) pairs at an even time interval.

The Cascade Historian has been built to allow quick addition of other forms of historical query.

Digital Room Correction project is a program used to generate correction filters for acoustic compensation of HiFi and audio systems in general, including listening room compensation.
DRC generates just the FIR correction filters, which can be used with a real time or offline convolver to provide real time or offline correction. DRC doesnt provide convolution features, and provides only some simplified, although really accurate, measuring tools.
For further informations see the documentation section, which includes the full manual of the current version of DRC and a complete set of measurements showing the effect of the DRC correction in a real life situation.
DRC is available for free and is released under the terms of the GNU General Public License. See the documentation for details.
Enhancements:
- A new feature for replacing command line parameters has been introduced.
- The dip and peak limiting procedures have been improved in order to avoid numerical instabilities.
- A new wavelet-based analysis graph has been added to the sample results.
- Many performance improvements have been introduced.
- A new optional parameter used to define the base directory for all files has been added.
