Visual Turing Machine 2.0
Visual Turing Machine is a program that lets you create Turing machines with a point and click interface. more>>
Visual Turing Machine project is a program that lets you create Turing machines with a point and click interface instead of using esoteric languages.
You can pack your complex machines into small boxes, and then reuse them as part of a bigger machine. VTM also features an infinite length tape.
Enhancements:
- New features include an n-ary set of symbols, multiple windows (MDI), a huge workspace (10000x10000 pixels) without a memory issue, the ability to edit your own machines, the ability to execute machines n times (where n is undefined), the ability to use expressions (like n+5) to execute machines, the ability to execute machines at desired speeds, statistics to see how many instructions were executed and how much tape was "used", and an easy wasy to translate the program to other languages.

Yet Another Time Machine 0.4
Yet Another Time Machine is a command line Ogg Vorbis and MPEG audio player. more>>
Yet Another Time Machine is a command line Ogg Vorbis and MPEG audio player with the ability to control the tempo of playback without changing the pitch.
Primary usage would be to listen (for example) to audio books at 150% tempo. This is still understandable and saves time, hence the name of the program.
The following audio encoding formats are supported:
- Ogg Vorbis
- Ogg Speex
- MPEG
- All formats supported by libsndfile (FLAC, WAV, AIFF, ...)
Enhancements:
- Version 0.4 adds support for libsndfile.
- There is also an undocumented gem, you can use < and > to slow down or speed up by 10%, and hitting SPACE can be used to pause playback.

C++ Machine Objects 0.9.4
C++ Machine Objects class library supports a subset of the UML statechart notation. more>>
C++ Machine Objects class library supports a subset of the UML statechart notation for implementing hierarchical state machines in straight C++, similar in spirit to the GoF "State" design pattern.
The currently supported features are hierarchical states, entry and exit actions, state histories, and state variables.
Installation:
The class library as such does not need to be installed. Just include the header file Macho.hpp to make use of it. Prerequisite however is a C++ compiler with sane support for templates.
Included are the example state machines HelloWorld, Example, Microwave and Test. To make the examples run just compile them in the directory they are in, for example:
# GCC
g++ -o microwave Microwave.cpp
# MSVC7
cl /EHsc Microwave.cpp
I like the GoF "State" design pattern. It enables implementing the important concept of state machines with common programming language features. By utilising only basic language mechanisms it is easy to apply in real-life software development.
Another important property that stems from this simplicity is orthogonality, meaning that the pattern can be combined with other design elements, patterns and idioms in arbitrary ways.
In contrast stand the tool supported approaches to state machine creation (of which there is no shortage). Based on code generators and graphical editors, they tend to generate incomprehensible code and forfeit orthogonality by necessarily being outside the domain of the programming language.
Unfortunately the "State" pattern is limited in scope because it does not allow for hierarchical state machines. This is regrettable because flat state machines tend to become unwieldy when getting bigger, for the sheer number of states they produce.
Hierarchical state machines as defined by the statechart notation alleviate this problem by giving an additional structural element through grouping states into hierarchies.
The "State" pattern in its original form is not capable of modeling state hierarchies. The Macho class library extends the concept with this possibility, while keeping the properties of simplicity (there possible) and tool independence from its inspiration.
Enhancements:
- This release adds the feature of backtracking to previous states by using "Snapshots".

Yet Another Machine Simulator 1.3.0
Yet Another Machine Simulator is a machine simulator which emulates the MIPS32 architecture CPU close enough. more>>
Yet Another Machine Simulator is a machine simulator which emulates the MIPS32 architecture CPU close enough. Should be fully compliant, but we cant claim that it is. It allows cross compilation with standard MIPS32 compiler back-ends.
YAMS also provides a very simple device interface to the simulated memory, disks, network interfaces, terminals and a real-time clock. There is also support for pluggable I/O devices. Pluggable devices are separate programs that implement the functionality of one or more devices and communicate with YAMS over a network or Unix domain socket.
Many features of YAMS are configurable. For example the number of CPUs can be configured. When the number of CPUs is more than one, YAMS simulates an SMP machine. The devices are also configurable. For example various delays for disks, terminals and network interfaces can be set.
YAMS also provides a hardware console which can be used to debug programs. The hardware console can be used to set breakpoints and dump the contents of registers, TLBs and memory. The memory dumping functionality also contains a disassembler.
Performanc:
The purpose of YAMS is to provide a very simple yet realistic simulated hardware platform for educational purposes. High performace (i.e. high clock speed) was not a factor in its implementation, so a normal slowdown factor between host clock speed and simulator clock speed is in the order of 500, resulting in simulator clock speeds of only a few megaherz.
So if you are looking for a fast MIPS emulator/simulator, then YAMS is not for you.
Enhancements:
- Better portability with pthreads and printf formatting macros.
- Minor bugfixes.

Kernel-Machine Library 0.1
Kernel-Machine Library is a C++ library to implement kernel machines. more>>
The Kernel-Machine Library is a freely available (released under the GPL) C++ library to promote the use and progress of kernel machines. It is both for academic use and for developing real world applications.
The Kernel-Machine Library draws heavily from features of modern C++ such as template meta-programming to achieve high performance while at the same time offering a comfortable interface.
It enables compile-time selection of specialised algorithms on the basis of data types: for example, the specific case of a SVM in combination with a linear kernel can be computed by a specialised efficient algorithm.
The Kernel-Machine Library has implementations for the following kernel machines and their cited algorithms:
- Support Vector Machine [1, 2, 3]
- Relevance Vector Machine [4]
- Kernel Recursive Least Squares [5]
- Adaptive Sparseness using Jeffreys Prior [6]
- Smooth Relevance Vector Machine [7]
Up till now, the focus has been on regression. The handling of classification and ranking problems is being added.

Virtual Machine Viewer 0.0.1
Virtual Machine Manager software is a desktop user interface for managing virtual machines. more>>
Virtual Machine Manager software (virt-manager for short package name) is a desktop user interface for managing virtual machines. The project presents a summary view of running domains and their live performance & resource utilization statistics. A detailed view presents graphs showing performance & utilization over time. Ultimately it will allow creation of new domains, and configuration & adjustment of a domains resource allocation & virtual hardware. Finally an embedded VNC client viewer presents a full graphical console to the guest domain.
The application logic is written in Python, while the UI is constructed with Glade and GTK+, based on mockups provided by UI interaction designers. The libvirt Python bindings are used to interacting with the underlying hypervisor. This enables the application to be written independant of any particular hypervisor technology. Initially Xen was the primary platform supported, however, since libvirt 0.2.0 and virt-manager 0.3.1 it is possible to manage QEMU and KVM guests too. It is expected that support for additional hypervisors / virtualization products will expand even further over time as additional libvirt drivers are written.
The "Virt Install" tool (virtinst for short package name) is a command line tool which provides an easy way to provision operating systems into virtual machines. It also provides an API to the virt-manager application for its graphical VM creation wizard.
The "Virt Clone" tool (virtinst for short package name) is a command line tool for cloning existing inactive guests. It copies the disk images, and defines a config with new name, UUID and MAC address pointing to the copied disks.
The "Virtual Machine Viewer" application (virt-viewer for short package name) is a lightweight interface for interacting with the graphical display of virtualized guest OS. It uses GTK-VNC as its display capability, and libvirt to lookup the VNC server details associated with the guest. It is intended as a replacement for the traditional vncviewer client, since the latter does not support SSL/TLS encryption of x509 certificate authentication.

Ragel State Machine Compiler 5.23
Ragel State Machine Compiler compiles state machines from regular languages. more>>
Ragel State Machine Compiler compiles finite state machines from regular languages into executable C/C++/Objective-C code. Ragel state machines can not only recognize byte sequences as regular expression machines do, but can also execute code at arbitrary points in the recognition of a regular language.
Ragel can also be thought of as a finite state transducer compiler where output symbols represent blocks of code that get executed instead of written to the output stream.
When you wish to write down a regular language you start with some simple regular language and build a bigger one using the regular language operators union, concatenation, kleene star, intersection and subtraction.
This is precisely the way you describe to Ragel how to compile your finite state machines. Ragel also understands operators that embed actions into machines and operators that control any non-determinism in machines.
Ragel FSMs are closed under all of Ragels regular language, action specification and priority assignment operators. This property allows arbitrary regular languages to be described. Complexity is limited only by available processing resources.
For example, you can make one machine that picks out specially formatted comments in C code, another machine that builds a list all function declarations and a third that identifies string constants then "or" them all together to make a single machine that performs all of these tasks concurrently and independently on one pass of the input.
Main features:
- Describe arbitrary state machines using regular language operators and/or state tables.
- NFA to DFA conversion.
- Hopcrofts state minimization.
- Embed any number of actions into machines at arbitrary places.
- Control non-determinism using priorities on transitions.
- Visualize output with Graphviz.
- Use byte, double byte or word sized alphabets.
- Generate C/C++/Objective-C code with no dependencies.
- Choose from table or control flow driven output.
Enhancements:
- The documentation and the Ruby code generator were improved.

Simple Machine Language interpreter
Simple Machine Language interpreter is a simple machine language interpreter. more>>
SML is a "toy" machine language intended to teach basic processor concepts. This website contains an explanation and definition of SML, as well as an interpreter and example SML programs. GPLd source code for the interpreter is available, as well as binaries for Windows and Linux.
A machine language defines a set of instructions that a CPU can execute to perform operations. In other words, a machine language defines what you can do with your computer. Modern processors have very complex instruction sets; however, the simple language described here can give you an understanding of what is happening "under the hood" with your computer.
Machine language is the actual data that is directly run by the processor. Writing a program in machine language can therefore be advantageous if you need to save space or highly optimize your code. However, machine language is also not portable and can be difficult to understand and maintain.
Therefore, almost all code is now written in a higher level language, such as C, C++, Java, or scripting languages such as shell or perl. These languages all have their advantages and disadvantages as well, such as varying levels of portability, maintainability, scalability, and execution speed.
One level higher than machine language is assembly language. Assembly language is basically readable machine language. Instead of writing out the code bit-by-bit, you write out the code as a sequence of human readable instructions, which are then compiled almost directly into machine language.
Assembly language is almost always used instead of machine language when such a direct level of control is needed. For example, some games implement part of their code in assembly in order to maximize execution speed. Assembly can be "inlined" into some higher level languages, like C. This means that the assembly is defined as a callable procedure from within the C code.

Concurrent Hierarchical State Machine 4.3
Concurrent Hierarchical State Machine (CHSM) is a language system for specifying concurrent, hierarchical, finite state machines more>>
Concurrent Hierarchical State Machine (CHSM) is a language system for specifying concurrent, hierarchical, finite state machines (an implementation of "statecharts") to model and control reactive systems.
CHSM uses its own statechart specification langauge annotated with either C++ or Java code fragments in the tradition of yacc grammars with C code fragments. The generated code is fully object oriented allowing multiple state machines to exist concurrently. The CHSM run-time library is small, efficient, and thread-safe.
CHSM has been used successfullly in production environments such as CERN, Philips, and Qualcomm. There is an independent review from users at CERN.
Enhancements:
- The "dominance" rule has been extended from parent/child transitions to sibling transitions.
- This allows "if-else" transitions to be done more efficiently.
