BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording, and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. It supports a wide range of audio inputs, outputs, and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console-mode user interface is included in the package.
The Easysoft ODBC-ODBC Bridge allows applications on one machine to access ODBC data sources on another. It supports multiple concurrent connections from multiple clients to multiple target databases. The principle application is to enable access from Linux and Unix platforms to remote ODBC databases. For example, Apache/PHP programs on Linux can read/write data held on MS SQL Server on Windows, and Perl programs can read/write data held in a MS Access database. Supported applications include Applixware, Open Office, Python, Rexx/SQL, mnGoSearch, OpenLDAP, and Oracle sqlplus. Supported platforms include Linux, MacOSX, IBM zSeries, Windows and various Unix flavors.
The unixODBC project provides Unix applications with the same ODBC 3.51 API and facilities available under Windows. It provides a Driver Manager that supports the full ODBC API and performs the ODBC 3 to ODBC 2 translations with UNICODE to ANSI conversion. It also includes a set of graphical utilities that allow users to specify connections to DBMSes to be used by applications, a collection of ODBC drivers including a simple text based driver, an NNTP driver, a Postgres driver and others, and a selection of templates and libraries that to aid in the construction of ODBC drivers. It works with MySQL, Postgres, StarOffice/OpenOffice, Applixware, iHTML, PHP, Perl DBD::ODBC, and many other applications and drivers. Connection pooling is also provided to increase performance with applications such as PHP.
SiteManager is an Open Source Web Application Toolkit for PHP Developers that includes a framework for code modules and layout templates, database connectivity, SmartForms, sessions, and some other tools. All parts of the system are integrated through object-oriented libraries which allow for easy expandability and maintenance.
PHP Mobile Mail is aimed at mobile professionals who want to use their favorite MUAs (noteably pine or mutt) on their laptop, either in UNIX or Windows (under GNU Gygwin). This lets you work offline. It includes a mail_spooler program, which accepts the output of you MUA and spools (on, or offline). When connected, another process parses through the spool and sends your messages. It is also designed to "fake" using your REAL email address with free services like gmx.net, or mail.yahoo.com, when using their POP and SMTP servers, assuming you have a domain and account that you can control to this degree.
