cstring is a small and simple platform-independent C library for the definition and manipulation of expandable C-style strings. Strings are represented as instances of the cstring_t structure, and manipulated by the library's functions. Its features include selection of different allocator pools, mapping cstring_t instances as views onto existing memory areas, efficient work-ahead memory optimization, and minimal link requirements.
Acogc is a simple garbage collector. It can coexist with other allocation strategies, as it is implemented on top of malloc/free. It uses a stop-and-copy algorithm. Its main goal is to be small and embeddable, not to be fast. It provides accurate cooperative collection, so the user has to supply custom marker functions for objects and must tag references on the stack manually. Swept objects are not destroyed, but are pooled in a free-queue and for faster reallocation. Weak references to swept objects can reinstantiate the object.
Twibright Luminaplex and Hyperluma 2 are two algorithms and an example implementation developed to encode (chroma subsample) Y'CbCr video at 4:2:0 and 4:2:2 scheme with higher quality than was currently possible. Ordinary encoding introduces errors, while Luminaplex eliminates virtually all error by finding the values of minimum error. It is published as a prior art to prevent coverage by a software patent.
