BitNami JRubyStack provides a fast, easy way to develop and deploy Ruby on Rails applications on a Java runtime using JRuby. It includes JRuby, Rails, Java, Tomcat, the GlassFish gem, MySQL, and Subversion. It supports Windows, Linux, and Mac OS X, so you can share the same Rails environment on multiple platforms.
BlueJ with Modified Error Subsystem is a modified version of BlueJ which has had the error reporting subsystem rewritten to find common programming errors that novice programmers make, report these errors in a descriptive way to reiterate the core concepts of programming, and give advice that the student can follow to fix the problem.
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.
DevContest is a tool for teachers of programming that makes it possible to create programming contests for your students. You prepare tasks, a description of them, an examle of the input and output, and a Python script that generates input and output. Students send their source code to the server and the system decides if they work well..
FastFlow is a pattern-based programming framework targeting streaming applications. It implements pipeline, farm, divide and conquer, and their composition, as well as generic streaming networks. It is specifically designed to support the development and the seamless porting of existing applications on multi-core, GPGPUs, and clusters of them. The layered template-based C++ design ensures flexibility and extendibility. Its lock-free/fence-free run-time support minimizes cache invalidation traffic and enforces the development of high-performance (high-throughput, low-latency) scalable applications. It has been proven comparable or faster than TBB, OpenMP, and Cilk on several micro-benchmarcks and real-world applications, especially when dealing with fine-grained parallelism and high-throughput applications.
