Open Cobalt. Open Cobalt is a free and open source software platform for constructing, accessing, and sharing virtual worlds both on local area networks or across the Internet, without any requirement for centralized servers.

Open Cobalt

The technology makes it easy to create deeply collaborative and hyperlinked multi-user virtual workspaces, virtual exhibit spaces, and game-based learning and training environments that run on all major software operating systems. By using a peer-based messaging protocol to reduce reliance on server infrastructures for support of basic in world interactions across many participants, Open Cobalt makes it possible for people to hyperlink their virtual worlds via 3D portals to form a large distributed network of interconnected collaboration spaces. Open Cobalt uses the Squeak software environment, which is an open source Smalltalk system freely available for Windows, Mac and Unix. Expected uses[edit] History[edit] In early 2008, and with the support of the Andrew W.

Distributed hash tables History[edit] These systems differed in how they found the data their peers contained: Napster, the first large-scale P2P content delivery system to exist, had a central index server: each node, upon joining, would send a list of locally held files to the server, which would perform searches and refer the querier to the nodes that held the results.

Distributed hash table

This central component left the system vulnerable to attacks and lawsuits. [citation needed]Gnutella and similar networks moved to a flooding query model – in essence, each search would result in a message being broadcast to every other machine in the network.

Security is all about adding on layers, like an onion, or an ogre, to establish what is called a defence in depth approach.

The more layers of security a bad guy must penetrate, the less likely he will succeed, the more likely you will detect him, and unless you are the specific target of the attack, they may just move on to easier pickings.

There are currently many research groups active in the field of photovoltaics in universities and research institutions around the world.

Solar cell research

This research can be divided into three areas: making current technology solar cells cheaper and/or more efficient to effectively compete with other energy sources; developing new technologies based on new solar cell architectural designs; and developing new materials to serve as light absorbers and charge carriers.

Study Finds Random Electrical Current May Help Folks Learn Math

You may one day swap coffee and cramming for a trusty set of head-mounted electrodes. According to a team of researchers, hailing from the UK and Austria, non-invasive electrical brain stimulation may improve math learning. However, the results, while intriguing, require a few requisite grains of salt: The trial was small, and as yet, there is no proven physiological explanation. The technique, called transcranial random noise stimulation (TRNS), sends weak electrical impulses racing between electrodes attached to the forehead. An early study using the technique suggested TRNS works by stimulating the brain’s ability to generate and propagate electrical potential, thus making it easier to forge new neural pathways.

The five day experiment tested shallow cognitive processing—students memorizing their times tables, for example—and deep cognitive processing, or the ability to learn a mathematical principle and apply it to solve a novel problem. Boost Your Brainpower.

Networks. In mathematical terms, a network is a graph in which the nodes and edges have values associated with them.

Networks

A graph is defined as a pair of sets. Mind Map - Index. Visualizing Hash Functions. I've been working on some static visualizations of hash functions, starting with SHA1 and MD5 (images here and here , respectively). The two sample images show the process of computing the respective hash functions on the input "denny" (with ASCII encoding -- i.e., the input in hex is "64656E6E79"). A portion of the MD5 image is included below: Notes about these two particular algorithms and their visualizations: Both algorithms are mostly defined in terms of operations on 32-bit "words", which essentially means 32-bit integers. They define the input/output conversion from sequences of bits/bytes to words, but this step is not covered in the diagrams. Baking Pi - Operating Systems Development.

Overview[edit] MapReduce is a framework for processing parallelizable problems across huge datasets using a large number of computers (nodes), collectively referred to as a cluster (if all nodes are on the same local network and use similar hardware) or a grid (if the nodes are shared across geographically and administratively distributed systems, and use more heterogenous hardware).

MapReduce

Processing can occur on data stored either in a filesystem (unstructured) or in a database (structured). Design Patterns. It has been highly influential to the field of software engineering and is regarded as an important source for object-oriented design theory and practice. More than 500,000 copies have been sold in English and in 13 other languages.

The term phreak is a portmanteau of the words phone and freak, and may also refer to the use of various audio frequencies to manipulate a phone system.

Phreak, phreaker, or phone phreak are names used for and by individuals who participate in phreaking. Because identities were usually masked, an exact percentage of prevalence cannot be calculated. History[edit] Phone phreaking got its start in the late 1950s. Its golden age was the late 1960s and early 1970s. Switch hook and tone dialer[edit] About Darknet.
