So-called machine learning does not cease to surprise, however for mathematicians the success reason is still not absolutely clear.

Somehow few years ago at supper, to which I was invited, the outstanding specialist in the field of differential geometry Eugenio Calabi volunteered to devote me in a subtlety of very ironic theory about a difference between adherents of pure and applied mathematics. So, having reached a deadlock in the researches, supporters of a pure mathematics quite often narrow a perspective, trying to bypass an obstacle thus. And their colleagues specializing in applied mathematics come to a conclusion that current situation indicates the need to continue studying of mathematics for the purpose of creation of more effective tools.

I always liked such approach; thanks to it it becomes clear that applied mathematicians will always manage to involve new concepts and structures which continually appear within fundamental mathematics. Today, when the question of studying of "big data" – too volume or difficult information blocks which do not manage to be understood is on the agenda, using only traditional methods of data handling – the tendency especially does not lose the relevance.

As practice shows — the big part of clients does not monitor the used resources, the services rented by them in any way (especially it is noticeable on the cheap services VPS from $3).

And, when there are problems with operability of the server, information for the analysis has not enough.

In this article procedure of installation and the collectd and collectd-web setup on the example of OS of Debian family will be described.

To learn to program more difficult, than it seems

1 year, 7 months ago

"El clasico" is simple

"There are a lot of letters", "did not master": as shows experience, programming demands existence of certain capabilities which are possessed by only small percent of the population of the earth. The modern mode on express courses in this area generates more and more speculation on a subject that does not promote growth of number of the qualified programmers at all.

This post is prepared taking into account realities of Great Britain, and therefore it is absolutely logical that in other countries the situation can look differently, in particular, so far as concerns the social status of software developers.

Mass media do not cease to cover the topic of shortage of the qualified programmers ("programmers", "encoders", "software developers" as all terms mean one and too, I will use from as interchanged). Disputes over an occasion of the low level of qualification of programmers are constantly conducted. In fact we are simply not able to prepare the frames corresponding to "solid requests of tomorrow". Here what is written by The Telegraph:

"According to data of Scientific Council, by 2030 the number of specialists in the field of information communication technologies will grow by 39%, and in the report of O2 for 2013 it was noted that the satisfaction of demand for such specialists during the period till 2017 will require about 745 000 new employees.

Besides, by results of the researches conducted last year City &Guilds, three quarters of employers from the sphere of IT, computer and information services noted explicit shortage of qualified personnel while 47% of respondents declared inability of the operating education system to train good specialists".

1 year, 7 months ago

From the translator:

This publication is continuation of the material "As There Is a Rendering of a Frame in GTA V"
. Now the author considers questions of detailing, lighting and post-processing of a frame. Pleasant reading.


Detail level


If we speak about absolute benefits of Rockstar over competitors, then indicators of the detail level of products of the company, definitely, above any praises. Los-Santos is the whole galaxy of various scenes of different extent of detailing / poligonalnosti, and all data are broadcast in real time and it for a minute does not block the loading screen. Just takes the breath away!

Fires of the night city


All sparks which are visible in the distance, real. You can closer approach and will see lamps which radiated light at distance.
