MirBSD originated as a patch set against OpenBSD-current, an ultra secure operating system and NetBSD derivate, and has since also incorporated changes from NetBSD, a 4.4BSD-derived ultra portable operating system. It features bugfixes, code removal for the sake of simplicity, and feature enhancements over stock OpenBSD as well as a much more up-to-date GNU toolchain, careful integration of patches from other projects (such as KAME), and many improvements. It works on the Intel Pentium and some 80486 machines with more than 32 MiB RAM and the SPARC, and a port to the PowerPC Macintosh is in preparation.
BeleniX is a distribution based on the version of OpenSolaris that runs on x86 machines. It comes as a live CD and includes all of the OpenSolaris components (core kernel, libraries, and utilities) and also includes additional GNU/OSS software. BeleniX is a full fledged OS distribution that can be installed and used as a regular desktop system.
The OpenBSD project produces a free, multi-platform 4.4BSD-based UNIX-like operating system. Its goals emphasize portability, standardization, correctness, proactive security, and integrated cryptography. OpenBSD supports binary emulation of most programs from SVR4 (Solaris), FreeBSD, Linux, BSD/OS, SunOS, and HP-UX.
SPJson is a simple stream-oriented JSON parser that supports pull-model and DOM-model JSON parsing. As the user passes it chunks of a JSON document, it identifies objects, arrays, or other entities and returns the appropriate event. Chunks can range from one byte to the whole JSON document. Resulting DOM trees can be read, modified, and saved.
