Ingres is a feature rich and robust database (RDBMS) that's free to use, modify, and redistribute. Support is available for a reasonable price if you need it. Ingres supports many programming languages, including Python, Ruby, Java, Perl, C/C++, and more. Ingres has a bit of a learning curve, but once mastered is extremely powerful and highly tunable. It is also very stable and reliable. Ingres is one of a fairly small number of databases providing excellent geospatial features including data types and functions compliant with the Open Geospatial Consortium (OGC) Simple Feature Specification (SFS) for SQL.
CGI::Application is a Perl framework intended to make it easier to create sophisticated, reusable Web-based applications. This module implements a methodology which can make Web software easier to design, easier to document, easier to write, and easier to evolve. CGI::Application builds on standard, non-proprietary technologies and techniques, such as the Common Gateway Interface and Lincoln D. Stein's excellent CGI.pm module. CGI::Application judiciously avoids employing technologies and techniques which would bind a developer to any one set of tools, operating system, or Web server.
Barcode Studio is designed to quickly create high-quality barcode images. It is commonly used for pre-press requirements, postal bar-coding, desktop publishing applications, mobile tagging, print shops, and general barcode purposes. It supports all linear barcodes (like Code39, 2of5, EAN, UPC, Code39, Code128, and EAN/UCC128), 2D barcodes (like PDF417, QR-Code, Aztec Code, DataMatrix ECC200, and MaxiCode), GS1 DataBar, and HIBC codes. Barcode data can be entered manually or imported from external data sources. Serial numbers are created automatically on demand. It has a built-in quality preview. Single as well as batch barcode creation is supported via the command line or the graphical user interface. Barcodes can be printed directly, copied to the clipboard, generated as image files (BMP, GIF, JPG, TIFF, or PNG) or exported as vector graphics (EPS, EMF, WMF , PDF, or PostScript). The created barcodes are useable immediately: Just insert the barcode graphics into your artwork, database, form, or any document.
Shinken is an advanced monitoring system that is based on Nagios, but redesigned and rewritten from scratch while maintaining compatibility. It can monitor all IT devices from systems to end user applications. In case of a failure, Shinken can alert the operation engineers so they can promptly repair it. It has the same capabilities as Nagios along with more advanced built-in facilities such as load balanced and high availability monitoring.
XSD is a W3C XML Schema to C++ translator. Provided with an XML instance specification (XML Schema), it generates C++ classes that represent the given vocabulary as well as parsing and serialization code. You can then access the data stored in XML using types and functions that semantically correspond to your application domain rather than dealing with elements, attributes, and text in a direct representation of XML such as DOM or SAX. XSD features support for in-memory and stream-oriented processing models, comprehensive XML Schema feature coverage, easy integration, and more.
Chicken is a Scheme compiler that translates most of R5RS Scheme into relatively portable C. It supports fully general tail-call recursion, first-class continuations, and has a very flexible and efficient interface to C and C++. Chicken implements several extensions to the Scheme language: lightweight threads, pattern matching macros, dynamic loading of compiled code, and various object-oriented paradigms, such as TinyCLOS, and others. The library system includes hundreds of convenient modules for practical use.
The Snack sound extension adds commands for sound play/record and sound visualization, e.g. waveforms and spectrograms. It supports in- memory sound objects, file based audio, streaming audio, WAV, AU, AIFF, and MP3 file formats, synchronous and asynchronous playback. The visualization canvas item types update in real-time and can output postscript. New commands and file formats can be added using the Snack C-API.
