Free operating room surgery software for linux

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.

Inferno is a compact operating system designed for building distributed and networked systems on a wide variety of devices and platforms.
Inferno was originally developed at Bell Labs (the research division of Lucent Technologies).
Inferno Operating System is a well-designed, economical operating system particularly suitable for use in networked devices such as advanced telephones, hand-held devices, TV set-top boxes, and many other embedded applications.
Inferno can run in native mode on an embedded system or in emulation mode under many different operating systems. Inferno has many features in common with Plan 9.
Cross-Platform Portability
Inferno can run as a user application on top of an existing operating system or as a stand alone operating system. Most of the popular operating systems and processor architectures are supported:
Host Operating Systems:
- Windows NT/2000/XP
- Irix
- Linux
- MacOS X
- FreeBSD
- Solaris
- Plan 9
Supported Architectures:
- Intel x86 (386 & higher)
- Intel XScale
- IBM PowerPC
- ARM StrongARM (ARM & Thumb)
- Sun SPARC
Inferno also runs as a plug-in under Internet Explorer version 4 and higher. Each Inferno system presents an identical environment to the applications, irrespective of the underlying host OS or architecture, allowing the developer to work with a truly homogeneous environment across multiple different platforms.
Portable Applications
Inferno applications are written in Limbo, a modern, safe, modular, concurrent programming language with C-like syntax. It is more powerful than C but considerably easier to understand and debug than C++ or Java. Limbo code is compiled into architecture independent byte code which is then interpreted (or compiled on the fly) on the target processor. This means that any Inferno application will run identically on all Inferno platforms.
Transparent Resources
Inferno offers complete transparency of resources and data using a simple but powerful namespace system. By representing resources as files and having one standard communication protocol, resources such as data stores, services and external devices can easily be shared between Inferno systems. A resource interface may be imported to the local system and used by the applications without them knowing, or needing to know, whether it is local or remote.
Security
High level security is an important part of the Inferno system. By using one standard protocol for all network communication, security can be focused on one point and provided at a system level. Inferno offers full support for authenticated, encrypted connections using a certificate based user identification scheme and variety of algorithms including:
- IDEA, 56 bit DES, 40, 128 and 256 bit RC4 encryption algorithms
- MD4, MD5 and SHA secure hash algorithms
A Complete Solution
Inferno is not only an operating system, it is also a complete development environment, providing all the tools necessary for creating, testing and debugging the applications that run within it.
- Acme IDE: includes editor, shell, advanced pattern matching tools & more
- Fast Compiler: with full syntax and compile time type checking
- Graphical Debugger: with full stack trace for currently executing threads
- Powerful Shell: with sophisticated scripting capabilities
- UNIX like commands: including bind, grep, gzip, mount, ps, tar, yacc...
Enhancements:
- New licence terms (a `dual licence scheme allowing use as Free Software)
- Styx revision based on 9P2000, and consequent changes to Sys
- Authentication changes
- Improved colour graphics support, including compositing
- Scalable fonts using Freetype
- Revamped Tk implementation
- Window management moved out of Tk to a separate window manager in Limbo
- Limbo: exception handling and fixed-point
- Limbo: other possible changes
- Dis VM changes
- More commands and library modules
- Better network service configuration
- /net/dns served by host and native DNS resolver
- Hosted kernels configured from a parts list as for native kernels
- Signed modules
- Internet Explorer plug-in revised and in source form
- Expanded documentation

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.

String::MFN is a Perl module to Normalize a string in the manner of the mfn utility.

SYNOPSIS

use String::MFN;

my $sane_string = mfn($retarded_string);
...

Normalizes a string. Normalization, in brief, means modifying the string to resemble a sane UNIX filename while retaining information carried by the original formatting.
Normalization, in specific, consists of characters other than [w-.+] being removed, lowercasing of all letters, separation of internaCaps, separation of leading numerals from trailing non-numerals, replacement of "bracketing" characters ({[()]}), replacement of ampersands, and collapsing (things that look like) repeating extentions.
