Myriahedral projections are a new class of methods for mapping the earth. The globe is projected on a myriahedron, a polyhedron with a very large number of faces. Next, this polyhedron is cut open and unfolded. The resulting maps have a large number of interrupts, but are (almost) conformal and conserve areas. A general approach is presented to decide where to cut the globe, followed by three different types of solution. These follow from the use of meshes based on the standard graticule, the use of recursively subdivided polyhedra and meshes derived from the geography of the earth. A number of examples are presented, including maps for tutorial purposes, optimal foldouts of Platonic solids, and a map of the coastline of the earth.

The suggested URI pattern is based on the distinction between non-information resources (abstract or concrete real-world objects), generic resources, and their representations. Generic resources are Web documents describing the abstract object they are associated with (e.g., a Dewey class). The pattern for generic documents defined in the current pool of Dewey URIs is as follows:

Library for Role based development.

Pythonic implementation of the DCI (Data Context Interaction) pattern (http://www.artima.com/articles/dci_vision.html).

The big difference with mixins is that this role is applied only to the subject instance, not to the subject class (alas, a new class is constructed).

Roles can be assigned and revoked. Multiple roles can be applied to an instance. Revocation can happen in any particular order.

Threading

We’re quite familiar with the idea of writing a program that follows a specific sequence of steps as outlined in, say, a main() function. A Thread is also a series of steps with a beginning, a middle, and an end. A thread’s sequence, however, can run independently of the main program. In fact, we can launch any number of threads at one time and they will all run concurrently. Visit the Java site for a more involved explanation.

This is incredibly useful when it comes to data mining, as we can have separate threads retrieving different pieces of information from the network. If one gets stuck or has an error, the entire program won’t grind to a halt, since the error only stops that individual thread. To create independent, asynchronous threads, we simply extend the Thread class.
