So, what is Isosurface – according to Wikipedia is a three-dimensional analog of an isoline. It is a surface that represents points of a constant value (e.g. pressure, temperature, velocity, density) within a volume of space; in other words, it is a level set of a continuous function whose domain is 3D-space. Let us take a look at the pictures:

These images show the surfaces with a different value “constant value” - the density. On the first image a value is less than on the second.

Many are looking for such studies, which would have been pleasant for the person, and useful in the development of certain skills for the programmers, and people with an office work.

1) Juggling

A Juggling is a wonderful thing that is healthy for health and for the soul. What benefit can we get from the juggling?
First of all, it is a good exercise for the eyes that removing the stress from them, which is important for the people that have been working at the computer. Then, this is the physical exercise (even if it is a small) as for the hands, so for the feet (at the beginning we will have to constantly bend over to pick up the falling objects). Finally, it is a moral satisfaction from the fact that you get to manipulate objects in the air. The juggling did not require any accessories. Only three (initially two) objects of such form that would be convenient catch and toss up preferably not too light or too heavy.

The Internet has many videos on how to learn to juggle, for example:

Well, the sweetest is juggling, which activates the mutual work of both hemispheres that stimulates the creative process and allows us to write a good code. The last thing is the speculation.

There is a very interesting book “The Psychology of persuasion” on the practical psychology that is written by Robert Cialdini.

Despite the fact that this book is devoted to the use of knowledge about the psychology of human behavior in the society, so many moments reflect the relations that arise between the seller and the buyer in this book.

On the first pages are given some examples of successful and effective management of customers and their buying behavior.
The book carries away a reader. In order to understand the essence of the article, let us read two brief stories from the author.

My neighbor is a jeweler; he is the owner of antique jewelry store. Once he told me like his own experience convinced him that is existence of the stereotype “expensive = good”. One of his friends was looking for a wedding gift for his bride. The jeweler just had a beautiful necklace for \$ 500 that he was ready to let his friend have for \$ 250. As a friend saw the necklace, he was delighted and wanted to buy it. But when he found out that the necklace was worth \$ 250, he immediately became sad and began haltingly to refuse, explaining that he was looking for his bride “something really worthwhile”.

People have known a saying “worst is first”, which I cannot say about my recent experience of the internet trade. Most likely, this is just an exception that proves the rule, but after all, I want to talk about those minor findings that I made last month.

So, it is a little story about how you can easily make for one month at least 15 000 Euros.

My professional career is a web-development. I do the R & D in a small IT company; I write “advanced” applications for the corporate intranets and, in principle, I do not complain about my life. Of course, in this scenario I would like to do some interesting project at the same time, what I have repeatedly engaged in the world of Open Source. Over the time, I wanted to make money on the side projects that with Open Source was not as easy as it may seem from the articles on the Habrahabr.ru :) That's why I decided to try for myself something entirely new - open an internet shop.

Microsoft made an unusually sharp statement that graphics technology WebGL, which has been promoted by the Khronos Group, is too dangerous in order to be supported in Windows.

Currently both browsers Google Chrome and Mozilla Firefox are provided with support of WebGL. Google calls this “the most powerful way to add 3D graphics on the web pages”and appeals to the developers “explore the field of graphic development “. Mozilla positions WebGL as the ideal technology for “interactive 3D games and applications with the rich graphics and realization of a new approach to the visual design without using other software components”.

In turn, Microsoft has published a statement entitled as “WebGL considered harmful” in the official blog of Microsoft Safety Center. It was published by a group that is responsible for the organization of security of Windows and other products Microsoft.
The statement was made after a pair of reports that describe the “serious design flaws” and “security problems” in WebGL. Last report includes a demonstration of how user data can be stolen through browser.

Despite the complexity with the project of Google Books, Google has been continuing to work towards the digitization of books, and today it has become known about the latest achievement of the corporation. Google corporation has concluded an agreement on the long-term cooperation with the British Library. In the Net will be posted 250 000 digital copies of books, starting with the publications of the 18th century within the scope of cooperation.

Of course, this is a fraction of the treasures that are kept at the British Library (about 150 million books), however, users can access the valuable publications, most of which will be available free of charge. The fact is that for most of the publications copyright has already expired.

#### Hi, everybody!

Today I would like to represent our small project named "UMumble" to You, and I suppose I will start from the beginning.
How did this idea start up?

One evening, surfing the Internet I came across an interesting project that combined a news portal with interestingly organized IT community. But why was it interesting to me?

At first sight, it was a common IT community voting for certain news items, thereby digging them up to the top (in seems to me that I have already seen it, for sure at digg.com). But getting deeper into it I noticed that its articles were quite professional although there was no editor at the resource. The articles were written by the community itself, and the community voted for them using special rating system. One could vote for anything including the users (thereby raising their positions at the rating table or banning them to write at the resource), topics, questions, comments etc. And such collective actions of the community prohibited (allowed for) certain activities .It was a sort of a role game. Considering that the resource was not English but quite, I discussed it and consulted with my colleagues and a decision to create a similar project was made. That's how "UMumble" appeared.
