Free running room software for linux

The goal of RUMT is to check the memory of a computer over a long period of time and almost-real load conditions without having to interrupt the services.

RUMT exploits the possibility of some Unix kernels to selectivly disable some memory areas while still accessing them through the /dev/mem device. The principle of RUMT is to write pseudo-random data in these disabled memory areas, and later check them. This principle and the original code for the deterministic pseudo-random generator are from David Madore.

This distribution contains another variant on the same theme: URUMT allocates a large chunk of memory, locks it in memory using the mlock(2) system call, and scans /dev/mem to find where in physical memory the allocated area is. Then it continuously runs the same tests in that memory.

URUMT can not be used to test a particular area of memory: the kernel will give it whatever physical memory it feels like. But URUMT can be restarted now and then, hopefully getting different physical memory each time.

This is perfect if you suspect you have bad bits, but do not know at all where they are. Once you have sighted the bad bits, you can use a plain RUMT to test more extensively the neighborhood.

Meeting Room Booking System (MRBS) is a free, GPL, web application using PHP and MySQL/pgsql for booking meeting rooms. This project is similar in concept to Netscape Calendar, but much cheaper!
Main features:
- Web/Intranet based - Available from any workstation through a Browser
- Simple to follow, Web based options and intuitive presentation
- Flexible Repeating Bookings
- Authentication with your existing user database (eg Netware, NT Domain, NIS etc.)
- Ensures that conflicting entries cannot be entered
- Reporting option
- Selectable DAY / WEEK / MONTH views
- Multiple auth levels (read-only, user, admin)
- Multiple languages supported (translated to Czech, Chinese, Danish, Dutch, Finnish, French, German, Greek, Italian, Japanese, Norwegian, Portuguese, Spanish, Swedish)
- Stable and in use at many organizations
- mySQL and Postgres support
MRBS is very reliable at this point. All the features that are needed in day-to-day operation are included. Its very intuitive for users, so very little or no instruction is needed. It is in production use at many large organisations around the world for uses as diverse as its originally intended meeting rooms to restaurant tables and aeroplanes at a flying school!
Different languages are supported, there are translations for many languages available (currently Czech, Chinese, Danish, Dutch, Finnish, French, German, Greek, Italian, Japanese, Norwegian, Portuguese, Spanish, Swedish). If your language is not supported it is very easy to customize as all strings are stored in language-specific files.
Enhancements:
- Extra options were added to the LDAP authentication scheme.
- You can now configure the cookie path used by the cookie and PHP session schemes.
- A short PHP start tag was fixed.
- Meeting duration can now use , as the decimal point.
- The Swedish translation was updated.
- AIX support was added.
- The language preference code was improved.
- Some bracketing in the month view was corrected.

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.
