  • Simplify the analysis of the OpenCL environment and of kernel requirements.
  • Allow for all levels of integration with existing OpenCL code: use as much or as few of cf4ocl required for your project, with full access to the underlying OpenCL objects and functions at all times.
Features:
  • Object-oriented interface to the OpenCL API
* New/destroy functions, no direct memory alloc/free * Easy (and extensible) device selection * Simple event dependency mechanism * User-friendly error management

Cloudgizer
Cloudgizer is a tool for building web applications as Apache modules in C language enhanced with simple markup, with emphasis on performance, small-footprint, and more productive and safer programming in C. It combines the ease of scripting with the power of C, improving the resource utilization for cloud applications. The programmer writes simple markup language mixed with C code, which is then translated entirely into C code and compiled natively as Apache module. The resulting application is fast and takes less memory, as there are no interpreters or virtual machines. Features include easy markups to use MariaDB database, HTML input parameters, cookies, simpler outputting of web pages, files storage and manipulation, encryption, encoding, program execution, web calls, safer and easier string manipulation etc. - the list is too long to place in one sentence. Overall Cloudgizer does a lot of stuff for you that you'd otherwise need to do yourself. A memory garbage collection system and memory overwrite/underwrite detection comes in handy for program stability. The same goes for string and memory handling markups to help write applications that won't crash. Also included is an application packaging system and an automated application installer. This makes rollout of products and release cycle more manageable. Cloudgizer source files have extension .v. Cloudgizer pre-compiler (cld program) will turn your .v files into .c files, ready for compilation as pure C programs. Then, your program will be compiled and linked with Apache web server on RH/Centos systems. It links with Apache as an Apache module in a "prefork" configuration. It does the work of communicating with Apache, and it makes it easier to write high-performance/small-footprint web programs in C. Cloudgizer is not designed to be thread-safe as it works in a "prefork" configuration of Apache. You can also build command-line programs. The same program can serve as both command-line utility and a web program linked with Apache. Cloudgizer works with RedHat/Centos 7 operating system, Apache web server and mariaDB database.
Cuba
The Cuba library offers a choice of four independent routines for multidimensional numerical integration: Vegas, Suave, Divonne, and Cuhre. They work by very different methods, first three are Monte Carlo based. All four have a C/C++, Fortran interface and can integrate vector integrands. Their invocation is very similar, so it is easy to substitute one method by another for cross-checking. For further safeguarding, the output is supplemented by a chi-square probability which quantifies the reliability of the error estimate.
DSSI
DSSI is an API for audio plugins, with particular application for software synthesis plugins with native user interfaces. DSSI is an open specification developed for use in GNU/Linux audio applications, although it is portable to other platforms. It may be thought of as LADSPA-for-instruments, or something comparable to VSTi. This package contains the header file required for compiling hosts and plugins.

FLIF
FLIF is a novel lossless image format which outperforms existing image formats in terms of compression ratio. It works well on any kind of image (photographic, line art, computer graphics, etc.) and also supports animations. FLIF images (or animations) can be progressively decoded, which makes the format potentially very suitable for responsive web design. This is the reference implementation of FLIF, which includes a command-line tool (flif) to convert between FLIF and PNG/PNM/PAM, a decoding library (libflif_dec), an encoding library (libflif_enc), some scripts (gif2flif, apng2flif, raw2flif, ...), and a simple image/animation viewer (viewflif).
Factory C
Factory C is Factory C because it uses a factory table that uses a strategic factory method(s) thats the singleton class factory method to the class interface heap for a factory table class. There are 3 levels of OOP in Factory C and thats Virtual, Factory, and Complex. The Complex object uses a runtime object for its interface inside of its own builder table and heap containers for its class interface heap and class information heaps, and runtime objects for its interface registrations. This (Factory C) is for fully dynamic-at-runtime Object-Oriented Programming with no limitations on things like datatypes or multiple inheritance or coupling. As a presentation of hash tables or data structures Factory C uses a Virtual Table, Factory Table, and an Adapter Table. there is a single linked list template you can typename, also a vector and binary search tree (heap). but only the datastructures needed to implement Factory C are included. Also, part or the Object-Orientation of Factory C is that every primitive type has a constructor plus interface as a virtual table object and factory method plus interface heap as a factory table class. The Complex object is created using a small class builder that is implemented in C.
Farstream
The Farstream (formerly Farsight2) project is an effort to create a framework to deal with all known audio/video conferencing protocols.

Fontconfig
fontconfig is a library for customizing and configuring fonts in a system, providing configuration, enumeration and substitution of fonts to other programs. Applications can use fontconfig in two ways:
  • by querying it for the available fonts on the system, or
  • by querying it for a font matching certain parameters (comprising a pattern) as closely as possible.
To perform font matching, fontconfig stores typesetting information about all of the installed fonts, including the name of the font family, style, weight, dots per inch (DPI), and Unicode coverage. This information is also used to perform font substitution.

Features

fontconfig can:

  • discover new fonts when installed automatically, removing a common source of configuration problems.
  • perform font name substitution, so that appropriate alternative fonts can be selected if fonts are missing.
  • identify the set of fonts required to completely cover a set of languages.
  • have GUI configuration tools built as it uses an XML-based configuration file (though with autodiscovery, we believe this need is minimized).
  • efficiently and quickly find the fonts you need among the set of fonts you have installed, even if you have installed thousands of fonts, while minimizing memory usage.
  • be used in concert with the X Render Extension and FreeType to implement high quality, anti-aliased and subpixel rendered text on a display.

fontconfig does not:

  • render the fonts themselves (this is left to FreeType or other rendering mechanisms)
  • depend on the X Window System in any fashion, so that printer only applications do not have such dependencies

GCC supports many different architectures and operating systems.
Gengetopt Heckert gnu.tiny.png
'gengetopt' takes an easy-to-do description of options and generates a C function that uses the GNU getopt_long(3) function to parse and validate the options. gengetopt is perfect if you don't want to write all the stuff required to call GNU getopt_long(3), or if you have a program and wish it took many options. The generated code works if you use autoconf or automake.
Geocode-glib
Geocode-glib allows you to do geocoding (going from a place name, to a longitude/latitude pair) and reverse geocoding (finding a place name from coordinates) using the Nominatim service. This library should be used in place of Geoclue's D-Bus API for geocoding and reverse geocoding.

Gnuae Heckert gnu.tiny.png
GnuAE is a GNOME/GTK compliant GUI for designing photovoltaic and wind powered houses with compliance to the National Electrical Code. As GnuAE has a database of components and current average prices, it can help you judge the total cost of a system by experimenting with different options like using a propane or DV fridge, or more or less reserve days or hours of sun. GnuAE is also designed to make it much easier to wire for NEC code compliance without studying all 800 some pages of the NEC specification. Even for an electrician, the interdependencies between calculations is daunting. While DC wiring is much simpler than AC wiring, most off-grid household systems are both. There is even a built in NEC calculator for people that have a good feel for what they are doing, but want to also experiment with differing conduit sizes, parallel wire runs, and voltage drop.
