SIMD-accelerated libjpeg-compatible JPEG codec library
libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.

Image library for Object Pascal.
Imaging is native Object Pascal (Delphi and FPC) image loading, saving and manipulation library. It is available for several platforms and does not require any third party dynamic libraries.
A C++ library for multiprecision complex-number matrix calculations.
zkcm library is a C++ library for multi-precision complex-number matrix calculations. It provides a number of functionalities including the LU decomposition, the singular value decomposition, tensor product calculation, tracing-out operations, etc.
C++ cryptographic library (modern hash functions, ciphers, KDFs)
cppcrypto provides optimized implementations of cryptographic primitives. Hash functions: BLAKE, BLAKE2, Groestl, JH, Kupyna, MD5, SHA-1, SHA-2, SHA-3, SHAKE, Skein, SM3, Streebog, Whirlpool. Block ciphers: Anubis, Aria, Camellia, CAST-256, Kalyna, Kuznyechik, Mars, Serpent, Simon-128, SM4, Speck-128, Threefish, Twofish, and Rijndael (AES) with all block and key sizes. Stream ciphers: HC-128, HC-256, Salsa20, XSalsa20, ChaCha, XChaCha. Encryption modes: CBC, CTR. MAC functions: HMAC, Poly1305. Key derivation functions: PBKDF2, scrypt, Argon2 (Argon2i, Argon2d, Argon2id). Includes sample command-line tools: - 'digest' - for calculating and verifying file checksum(s) using any of the supported hash algorithms (similar to md5sum or RHash). - 'cryptor' - for file encryption using Serpent-256 algorithm (CBC mode with HMAC). Check out the cppcrypto web site linked below for programming documentation and performance comparison.
Useful crossplatform library for distributed systems
Platform-Independent Primitives. Contain string, thread, timer, file, config file, serial port, ethernet (UDP, TCP, broadcast, multicast), protocol, multiprotocol, peer, console, variable, struct, evaluator, system monitor (Linux only), CLI (command-line interface) parser. Package include library that you can build with 'qmake' or 'CMake' and test program in 'main.cpp'. Online documentation: http://ppip.sourceforge.net/doc/
Extract the TLD of any, world wide, URI.
The libtld is used to extract the TLD from any URI from anywhere in the world. The library recognizes all TLDs, whatever the number of levels the TLD includes (i.e. .com has one, .au has up to 4 such as .schools.nsw.edu.au) this library will be capable of extracting it. The library is for C, C++, and PHP.
This project has moved to GitHub https://github.com/Zipios/Zipios Zipios is a C++ library for reading and writing Zip archive files. Access to the data of individual entries is provided through standard C++ iostreams. A simple read-only virtual file system that mounts regular directories and zip files is also provided.
Extended C Library
Why Is libxc needed? There doesn't exist a library for ANSI C99 for common data containers, such as vectors, trees, etc. There also also doesn't exist a library for common functionality, such as error reporting/logging, string functions, configuration management (reading config files), etc... The programmer working in C doesn't have anything analogous to the Boost C++ library. The extended C library is intended to make some headway into providing this functionality. To ensure unrestricted usage the libxc project is provided under the very permissive BSD license. If you need a different license then please send me a request (lelanthran at gmail) and I'll do my best to satisfy your request. What's completed? As of writing, the following libraries have been written and tested: 1. Memory accounting/tracking 2. String operations 3. Vectors 4. Trees 5. Dictionary arrays 6. Configuration management See the wiki page for more information
Management and simulation of Electric Vehicles activities
EVLib is a library for the management and the simulation of Electric Vehicle (EV) activities, at a charging station level, within a Smart Grid environment. EVLib provides a simple, yet efficient interface for the management of all major EV related activities such as the charging and dis-charging of batteries, as well as battery swapping. Moreover, a large number of parameters, such as the number of chargers, the waiting queues, and the available energy can be easily configured. On top of this, the library supports the simultaneous operation of many EV activities through the efficient use of threads.
a CLI generator and and SW library
CLIck allows you to create flat or hierarchical CLI (command line interfaces) in an extremely easy and quick way, supporting very popular features like history with command recalling, context-based auto-completion, tab-based command list, automatic command-line help, special characters, automatic structure builder, and much more. CLIck is written in ANSI C and tested on C and C++ applications on several architectures. It doesn't depend on any external library and uses only a very small subset of POSIX APIs. Despite the project name, you won't need your mouse at all!
