cpuburn is is a set of programs that load x86 CPUs as heavily as possible for the purposes of system testing. FPU and ALU instructions are coded in an endless loop in an attempt to maximize heat production from the CPU, putting stress on the CPU itself, the cooling system, the motherboard (especially voltage regulators), and power supply. The tests may damage undercooled, overclocked, or otherwise weak systems and cause data loss or permanent damage to electronic components.
Fiwix is an operating system kernel based on the Unix architecture and fully focused on being Linux compatible. It is designed exclusively for educational purposes, so the kernel code is kept as simple as possible for the benefit of students. It runs on the 32-bit x86 hardware platform, and is compatible with a good base of existing GNU applications.
ADTPro transfers disks to and from Apple II and Apple /// computers and the modern world using any of these communications methods: serial/USB, UDP via the Uthernet or LANceGS Ethernet cards, or audio via the Apple's cassette ports. ADTPro has comprehensive bootstrapping support for otherwise diskless Apple IIs. The home page includes extensive tutorials for getting started.
The dyncall library project provides a clean and portable C interface to dynamically issue foreign function calls using small call kernels written in assembly. Instead of providing code for every bridged function call, which unnecessarily results in code bloat, only a modest number of instructions are used to invoke all calls.
HLA Adventure is an adventure game that was written in Randy Hyde's HLA language. It features Mippy, a cute dragon that lives happily in the forests and caves and often comes out during the later part of the day to eat leaves, smoulder decaying trees, and generally romp around like every good dragon should.
libposix is an impementation of the core functionality of all Unix systems. It is a full, cross-platform implementation of the POSIX 2008 standard. It is meant to replace existing implementations of a Unix system's core libraries. It is an exact implementation of POSIX 2008 and nothing else (no extensions, no previous POSIX versions). However, it works well with possible extensions to the core system functionallity (for example, GNU or BSD).
HAVEGE (HArdware Volatile Entropy Gathering and Expansion) is a user-level software unpredictable random number generator for general-purpose computers that exploits modifications of the internal volatile hardware states as a source of uncertainty. It combines on-the-fly hardware volatile entropy gathering with pseudo-random number generation. The internal state includes thousands of internal volatile hardware states and is merely unmonitorable. It can support several hundreds of megabits per second on current workstations and PCs.
The Smart Card Detective (SCD) is a general framework for research on smart cards. It allows you to monitor any smart card application (including Chip and PIN / EMV transactions) and create your custom applications. The software is completely open source, and the hardware can be bought from Smart Architects. The device has a smart card interface as well as a terminal/reader interface, allowing the SCD to act as a passive/active monitor between a card and a reader or emulate a card or a terminal. Using the Python command line interface, you can interact with the SCD using a PC. This allows more flexible operation, although the SCD also features many stand-alone applications and a battery so that you can also use it without a PC.
