Cloud Computing White Paper

The cloud computing does not represent a product or a service. It’s not a technology either.
There are a great number and different definitions of cloud computing. There are several of them:
* Cloud computing represents a style of computing in which the IT power is submitted like a service to the users by the help of the Internet technologies.
* Cloud computing is a model which is a kind of provision of convenient web access to a pool, configured by computer sources which could be operational used.
The users of cloud computing decrease their expenses for infrastructure using the elastic in the cloud computing.
Characteristics.
There are some characteristics of the cloud computing:
– Self service on demand
The user all alone defines and changes the computing needs. They are server time, the speed of the process of accessing and treatment of the information, the size of the stored data and others.
– Universal admission to the network
The services are always accessible to the user
– Resource pooling
The provider of cloud service unites resources for calculating of big number of clients in a pool which rearranges the power between the users in condition of full change of applications.
– Elasticity
All the services could be shared, changed and developed all the time without a need of a relationship with the provider.
– Report of use
The provider of the service automatically calculates the usage of the resource and on the base of that data they evaluate the submitted IT services that the user used.
There are also different models of realization of the cloud computing:
Private cloud
That is an infrastructure that is made for the usage of one organization that includes a couple of customers or clients for example.
Public cloud
This is an infrastructure that is made for wide public use for everybody. It could be owned by all kind of different organizations.
Hybrid cloud
That is a combination of many and different clouds that are connected with each other.
Community cloud
This is an infrastructure that is made for usage of concrete users or organizations that have something in common. The community cloud could be owned by that organization and user or co-owned with a third side.
Models of services:
The quality of the services depends on the models which help the delivery to the users.
– Software as Service (SaaS)
That is a model in which the user has the opportunity to use an application software which is owned by the provider. The model works in a cloud infrastructure and is accessible from different client devices. The control and management is of course done by the service provider.
– Infrastructure as a Service (IaaS)
That is a model in which the customer has the access to the whole cloud infrastructure – virtual server, data base and web equipment. The user can control his own operation system and own data base.
There is some criteria on which the cloud computing could be compared.cloud computing
One of the things is the orientation towards business. Another thing is the elastic scalability and last but not least integration of system components.
Nowadays cloud computing is one of the most common and famous things in the IT world. According to different sources the market of the cloud computing in 2009 is about 17 million dollars which is almost 5% of the whole IT’s market.

Electronic Music Theory: 8 Rhythmic Devices You Should Know (Polyrhythm, Syncopation +)

Image
 I wrote about the primary elements of drum beats: measured time, drum sound selection, and the observable phenomenon of 2s and 3s. Truth be told I wrote that article to get you thinking about rhythm in a different way so I could follow it with this article. I will go over some rhythmic devices that I’ve picked up over the years from working with drummers and percussionists in a variety of live performance and studio recording situations. Being that this is a series dedicated to how music works (music theory), it is appropriate to include some examples of recorded music that utilizes these techniques, which I will do for you below. Once you’ve internalized these concepts and can recognize their idiosyncratic sounds, you’ll start hearing them all over the place. If you have any questions, feel free to ask them using the comment section down below. Alright, let’s jump in. This one example includes all eight rhythmic devices that we’ll cover below:  the downbeat ,  the up

Computable Universes & Algorithmic Theory of Everything: The Computational Multiverse

Digital Physics: Is our universe just the output of a deterministic computer program? As a consequence of Moore's law, each decade computers are getting roughly 1000 times faster by cost. Apply Moore's law to the video game business. As the virtual worlds get more convincing many people will spend more time in them. Soon most universes will be virtual, only one (the original) will be real. Then many will be led to suspect the real one is a simulation as well. Some are already suspecting this today. Then the simplest explanation of our universe is the simplest program that computes it. In 1997 Schmidhuber pointed out [1] that the simplest such program actually computes all possible universes with all types of physical constants and laws, not just ours. His essay also talks about universes simulated within parent universes in nested fashion, and about universal complexity-based measures on possible universes. Here a few video clips on this from the World Science Fest

Balancing your Studies and Social Life at University

When you add up all the course work and social opportunities, the uni experience can be overwhelming, and one of the worst parts is feeling like you have to sacrifice part of your study time for a party or vice versa. But fear not!  The university experience doesn’t have to be all work or all play  – there are ways to have a successful academic career and still have time for fun. The key to making it through is finding a way to balance your studies and social life, by setting realistic expectations, staying organised and having interim goals. Set the right goals A good goal is one you have to stretch to achieve, but is not so unreasonable that you’d have to drop everything else to get there. Try to get into the habit of setting goals not only for your academic life but other parts of your university experience as well. Break your course work into achievable segments.  Instead of waiting until the last minute to study for an exam or start a big project, set intermediate daily o
