dispy is a Python framework for parallel execution of computations by distributing them across multiple processors in a single machine (SMP), or among many machines in a cluster or grid. The computations can be standalone programs or Python functions. dispy is well suited for the data parallel (SIMD) paradigm where a computation is evaluated with different (large) datasets independently (similar to Hadoop, MapReduce, Parallel Python). dispy features include automatic distribution of dependencies (files, Python functions, classes, modules), client-side and server-side fault recovery, scheduling of computations to specific nodes, encryption for security, sharing of computation resources if desired, and more.
distributed.net is a loosely knit group of computer users from all of the world that is taking up challenges requiring lots of computing power (most notably the RC5, DES, and OGR cracking contests). It is simple to participate in the challenges by downloading and running their client software (which uses idle CPU time to complete its tasks).
djib is a streaming server for media (MP3, Ogg Vorbis, video, etc.) files, with a Web frontend allowing the user to browse the collection of available files over the Web. Links to the actual media files allow an HTTP-aware media player (such as Windows Media Player, XMMS, WinAmp, FreeAmp, etc.) to play the files.
dmap2gcode is a depth map image cutting program. A depth map is a greyscale image in which the darkness or lightness of each pixel corresponds to the depth (or height) of the object at each point. dmap2gcode supports various cutter geometries (flat, ball nose, and v-bit), two types of cut entry (straight and arc), a full set of roughing options, and various other settings, all controlled through a graphical user interface. The g-code output from dmap2gcode is compatible with LinuxCNC and Mach3.
