"Extended Data Types for PHP" is a collection of PHP5 classes, which provide easily usable common data types like Lists, Trees or Graphs. Installation will be possible via an PEAR Channel or as local library in a website's code base.

XSWAG (Extended SourceWare Archive Group) is a revival project for the famous SWAG code archives for the Pascal programming language. This project is open to every Pascal/Delphi programmer who wishes to contribute to the global Pascal knowledge base. Current version (testing 0.9) features : - a reader program : allows users to browse through the code archives, organizes them by type and operating system and updates the archives from multiple XSWAG servers. - a server daemon : maintains a list of archives and provides updates to clients. - a creator program : to quickly make or modify an XSWAG archive file, add/remove sources and update sources info (os, compiler, architecture, contact info, author name, subject).

An extensible and compressed trie data structure written in C++.

ExtraDix is a sorting algorithm based on Radixsort. It is faster than Quicksort, stable, realized in C and can sort by any basic data type. Testing was done with 1 million data records sorting char, short, int, long, float, double and strings.

FATE (Federated AI Technology Enabler) is the world's first industrial grade federated learning open source framework to enable enterprises and institutions to collaborate on data while protecting data security and privacy. It implements secure computation protocols based on homomorphic encryption and multi-party computation (MPC). Supporting various federated learning scenarios, FATE now provides a host of federated learning algorithms, including logistic regression, tree-based algorithms, deep learning and transfer learning. FATE became open-source in February 2019. FATE TSC was established to lead FATE open-source community, with members from major domestic cloud computing and financial service enterprises. FedAI is a community that helps businesses and organizations build AI models effectively and collaboratively, by using data in accordance with user privacy protection, data security, data confidentiality and government regulations.

This library is being created as I have a need to do very fast FFTs on low end devices not supporting the NEON instruction set. The Raspberry Pi is an ideal candidate for developing in gcc before porting to JNI for low spec Android devices, hence it's inclusion. Fixed point 16/32 integer FFT library suitable for the Raspberry Pi and Android devices. Includes test stubs for gcc on the Raspberry Pi and a Basic4Android wrapper from JNI. It includes hand optimised ARMv6 assembler, demonstrating techniques such as pipeline stuffing to achieve maximum performance. It also demonstrates how to include large chunks of assembler inline with C/C++ thus avoiding ABI issues between platforms.

Flexible job shop scheduling problem (FJSP) is very important in many fields such as production management, resource allocation and combinatorial optimization. In the real manufacturing systems, each operation could be processed on more than one machine and each machine can also process several operations. This feature is known as flexibility. You can define your problem in this software and get an optimal solution as a Gantt Chart. This software is based on my M.Sc. thesis of Shahed university (Tehran, Iran).

Fuzzy Procedural Content Generation Library (FPCGlib) is a C++ template library for game development. FPCGlib provides a unique combination of fuzzy mathematics and procedural techniques to safely generate content with simulated natural variability.

FPM - Fixed Point Math substitutes expensive floating point operations by much cheaper integer arithmetics. Use this library in your plain C (gcc) projects if you like.

FRODO is a Java platform to solve Distributed Constraint Satisfaction Problems (DisCSPs) and Optimization Problems (DCOPs). It provides implementations for a variety of algorithms, including DPOP (and its variants), ADOPT, SynchBB, DSA...

A high-performance functional, set-theoretic collections library. All collections are immutable; updates return a new collection. Supports arbitrary nesting (sets of sets etc.). Implemented with heterogeneous binary trees. Lisp and Java; more to come.

FUMOLA is a co-simulation framework specifically designed to support the features offered by the FMI specification. It provides a flexible platform that allows to configure and execute co-simulation setups in an easy way. FUMOLA is developed on top of the Ptolemy II framework (https://ptolemy.eecs.berkeley.edu) and the FMI++ library (http://fmipp.sourceforge.net). The online documentation of FUMOLA is available here: https://sourceforge.net/p/fumola/wiki/Home/

Libface is a cross platform framework for developing face recognition algorithms and testing its performance.

Provide geneology information, contact information, personal descriptions and webpages, calendars, etc in a web interface. This system will use php and any database system and will provide various level of public and private access.

This projects hosts the worlds fastest algorithms for the labeling of point-features. It especially looks for algorithms thar are free of constraints, applicable to many scenarios (e.g., visualization, maps...) and do not need any preprocessing.

A cross-platform library that computes fast and accurate SIFT image features. libsiftfast provides Octave/Matlab scripts, a command line interface, and a python interface (siftfastpy). Optimized with SIMD instructions and OpenMP .

Significant gains in processing times when sorting arrays with structure in the data. Pre-sorted arrays with relatively few modifications may be sorted 20-30 times faster than Delphi's default QuickSort. The project includes a test suite.

Libraries providing optimized alternative implementations for Delphi VCL/RTL functions, methods and classes.

FastFlow is a C/C++ programming framework supporting the development of pattern-based parallel programs on multi/many-core, GPUs and distributed platforms. FastFlow run-time is built upon non-blocking threads and lock-free queues. Thanks to its very efficient CAS-free communication/synchronization support (e.g. few clock cycles core-to-core latency), FastFlow effectively supports the exploitation of fine grain parallelism, e.g. parallel codes managing very high frequency streams on commodity multi-core. FastFlow works on x86, x86_64, PPC, ARM, and Linux, Mac and Win XP/7. From Jan 1, 2018 code development migrated on GitHub at https://github.com/fastflow/fastflow

This is showcase program, with source code and sample data included for fast peak detection algorithm. It is great tool for entry level, automated analisys, to discard empty and junk curves and save only ones matching required criteria. Assuming that only 1% of data is worth reviewing, and that manual selection takes approx. 3 seconds per curve, you can save up to 8 hours per every 10000 curves (like 2 days every week!). Force amplitude analisys for single curve takes from 1 to 4 milliseconds on low-end intel dual core. Algorithm is so simple, that you can implement it in any language in few hours, without any specialized libraries. To be implemented in our Nanopuller AFM control software as real-time module. Requires LabVIEW Runtime engine to run .exe or LabVIEW 2013 for code.

This is a tidy lightweight library implementing a series of C++ Design Patterns, aiming to be simple, clean and portable. This library is made to help C++ programmers to develop projects with clearer and more compact source code.
