CPC (Continuation Passing C) is a programming language designed for writing concurrent systems. The CPC programmer manipulates very lightweight threads, choosing whether they should be cooperatively or preemptively scheduled at any given point; the CPC program is then processed by the CPC translator, which produces highly efficient event-loop code. This approach gives the best both worlds: the relative convenience of programming with threads, and the low memory usage of event-loop code. The semantics of CPC is defined as a source-to-source translation from CPC into plain C using a technique known as conversion into Continuation Passing Style. The current implementation of CPC has been used to write Hekate, a BitTorrent seeder designed to handle millions of simultaneous torrents and tens of thousands of simultaneously connected peers.
Qt for Urbi is a binding of the Qt library in Urbi, enabling you to create native graphical interfaces dynamically directly from Urbi. It exposes urbiscript events to ease the use of Qt signals and slots. Major and minor version numbers of the Qt for Urbi packages reflects the Urbi SDK version number for which they were built. Loading it in another version of the Urbi kernel probably won't work. For instance, Qt for Urbi 2.4.x will only work with Urbi SDK 2.4.y. It is still a bit experimental. Only the 32-bit Linux version is available, and not all classes and members are bound yet.
Charm++ is a portable adaptive runtime system for parallel applications. Application developers create an object-based decomposition of the problem of interest, and the runtime system manages issues of communication, mapping, load balancing, fault tolerance, and more. Sequential code implementing the methods of these parallel objects is written in C++. Calls to libraries in C++, C, and Fortran are common and straightforward. Charm++ is portable across individual workstations, clusters, accelerators (Cell SPEs and GPUs), and supercomputers such as those sold by IBM (Blue Gene, POWER) and Cray (XT3/4/5/6). Applications based on Charm++ are used on at least 5 of the 20 most powerful computers in the world.
Larceny is a simple and efficient implementation of the Scheme programming language. Created originally as a test vehicle for research on garbage collection and compiler optimizations, Larceny has grown into a major multi-platform system, and is one of the very few implementations that support all four de facto standards for Scheme: IEEE/ANSI, R5RS, ERR5RS, and the R6RS. Development of Larceny has been supported by NSF, Sun Microsystems, and Microsoft.
mbrChunker is a utility that allows you to mount raw disk images (created by dd, dcfldd, dc3dd, ftk imager, etc.) and create VMDK files. It does this by taking the raw image, analyzing the master boot record (physical sector 0), and getting specific information that is need to create a working VMDK file that points to your raw image. It can also extract information such as heads, cylinders, and sectors per track. With version 0.3.15, the tool now has the ability to search for hex byte offsets within any binary file. It will give you the byte location for every hex pattern found. More information about this can be found in the README.
I is a programming language that was designed to be efficient to write and run. The system incorporates many major libraries, allowing the creation of major projects such as Aciqra. It is an interpreted language and supports CGI scripting through the use of the CGI for Aciv/I extension.
Shannon is a general purpose stream-oriented programming language; it is concise and yet feature rich. Streams, FIFOs, and Unix shell-style pipes are first-class concepts in the language. You can connect functions and FIFOs within your program similar to the way you connect processes with pipes in the Unix shell. These constructs in Shannon, however, are highly efficient as no true multitasking is involved, and at the same time they allow you to write more concise and readable code for chained data processing. State is a special type of function that returns a reference to its own local data and any nested functions it may have. In effect, states implement classes in terms of OOP, and yet classes per se aren't part of the language. A special type of modules marked as "persistent" is an effective replacement for databases and SQL. This allows you to access persistent shared data using native Shannon constructs, eliminating the need for an extra query language. Intuitive and minimalist syntax and semantics are used. Particularly, "minimalist semantics" means less things to remember and more possibilities. Shannon is statically-typed, although it provides dynamic typing facilities as well.
Hybris (hybrid scripting language) is a dynamic scripting programming language created to help developers to automate everyday procedures in a easy and fast way. Although is a high level language, Hybris supports dynamic library linking, native C function calls, and a lot of other low level functionality.
Crules is a dynamic programming language that takes influences from Python, Perl, and Haskell. The main motivation for this language was the concept or design of a new paradigm or feature called "rules". A rule is a potential entry point which has dependencies rather than parameters. Any rule can be overridden to have different or no dependencies. Since the language itself can decide on the best course of actions for an operation, dependencies become preconditions for execution. It also features lazy evaluation, object orientation, variadic and anonymous-parameter functions, and reflection. These features help make the language truly dynamic.
