Results in April

One day in April I was not impressed. In general,. Expected results are much better than getting.

The action brought a lot of software somewhere on the sales and the total turnover of about 50tys. rubles. It is unusual to many, made ​​me think about the fate of this unit. Moreover, income is shared roughly equally between the engines and the panel, which leads to even greater reflection.

Kazapka issued the results of March, although the expected rise. But now everything is clear. We detain up, the overall information support has fallen, the influx of newcomers weak. In general, there is a tendency to enlargement of advertisers - the number of large payments increased, and the average match the number with a minimum. T. e. quantify those who use the system as an instrument, it was about the same as trying to taste.

Rent in April gave a result that exceeds the sum of the previous three months. On the one hand, it is nice, but on the other - this is the first in the history of steel a month seasonal. After all, we started in September when the season was already a spent. In addition, the result, though pleasant, but not too great to relax. We'll see in May, when the garden season, more will be added and tourism. And we some beasts kalyaku malyaku - painted on the shield. Damage slight, but annoying.

Most welter in the situation of the search traffic. If the all clear by Google, and is stable, then Yandex month wagged its tail a few times, then disrupting the balance, then it partially restores. So cutting off the index, improving on the same sites of the position. Previously, I had some explanation, now just waiting for when it's at least some stability in order to indulge in the analysis.

On a tangent all of this is reflected in other projects: Employment grew and makes it impossible to hold the post in the blog, marketing, new projects and just a literary work. Blog showed a small drawdown of traffic, not even reached already familiar 9tys. uniques per month, although the volume of traffic from external sources remained the same.

April this year came out very sluggish, which is slightly annoying. Let's see whether the downward trend in May and will increase still.

The Kola borehole - the way to hell

Since ancient times people have tried to understand the structure of the bowels of the planet. However, for a long time to drill the earth's firmament more than a few hundred meters could not - was not the necessary equipment. Therefore, all ideas about Earth's internal structure is based mainly on theoretical calculations, which has not yet been confirmed by experimental data.

According to conventional wisdom, the earth is composed of three major layers: core, mantle and crust. In the center of the nucleus is divided by an internal solid area ( radius of about 1300 km ) and the liquid outer core radius of about 2200 km, among which stands out is sometimes a transition zone. It is believed that this area of ​​the planet is composed of iron-nickel alloy.

Next is the mantle - a layer consisting of silicates of magnesium, iron, calcium and other metals. It extends from depths of 5-70 km below the Earth's crust, to the border with the nucleus at a depth of 2900 km. It is believed that the mantle is hot enough, and in some layers of the substance remains in the molten state.

The upper layers of the mantle in contact with the earth's crust - thus a layer in which we actually live and. The thickness of the outer shell varies from a few kilometers ( in oceanic areas) up to several tens of kilometers ( in the mountainous regions of the continents ). Field of the Earth's crust is very small, it accounts for only about 0.5% of the total mass of the planet. The basic structure of the cortex - is oxides of silicon, aluminum, iron and alkali metals.


It is believed that the composition of the continental crust, comprising a top layer of sediment ( granite ) and bottom ( basalt ), are the most ancient rocks of the Earth, whose age is estimated at more than 3 billion years. The oceanic crust is a young and thin - a savings deposits (their age is not more than 100-150 million years ) has only one layer, similar in composition to basaltic.

It turns out that for the time of its existence, people are not really able to explore even the earth's crust, and only that would ' feel ' the mantle or the core, so this for many years one of the scientists did not dare even to dream. However, in the middle of the twentieth century, the necessary equipment for such research has finally been developed, and the dream began to turn into reality.

Projects journey deep into the earth began in the early 60s of last century in several countries. Tried to drill in those places where the crust had to be thinner, since the purpose of this drilling was to reach the mantle, kotoruyu-to, in fact, going to study in detail.

For example, Americans were drilled near the island of Maui, Hawaii, where, according to seismic studies, ancient rock out under the ocean floor and the mantle is approximately at a depth of five kilometers (under chetyrehkilometrovoy water column ). However, none of ocean drilling deeper than 3 km could not get through.

In general, almost all projects ultradeep wells mysteriously ended at a depth of three kilometers. It was at this point with the Boers began to be something strange: they fall into unexpected areas with a high temperature, they seemed a bit off the mysterious underworld demon. So in most cases could not even learn of the deep layers of the earth's crust, not to mention the mantle, the study of which, strictly speaking, and represented the true purpose of this research.

And then, in 1970 on the Kola Peninsula has been the drilling of the well-known Kola borehole. The point chosen for this drilling location of the peninsula is not accidental - the peninsula is located on the so-called Baltic Shield, which is composed of the oldest breeds known to man. Work at the site were from 1970 to 1992. During that time managed to ' pierce ' the earth's crust at 12 262 m.

Interestingly, when in 1984 took place in Moscow International Geological Congress, which presented the first results of the well, many scientists jokingly offered to immediately bury it because it destroys all of the structure of the crust. Indeed, the strangeness began in the early stages of penetration. For example, theorists have yet to start drilling promised that the temperature of the Baltic Shield remain relatively low to a depth of at least 15 kilometers. Accordingly, the hole can be dug up almost 20 kilometers, just prior to mantle.

However, at a depth of five kilometers of the ambient temperature is exceeded for the 700C, the seven - for the 1200C, and at a depth of 12 kilometers of sensors already recorded 2200C - 1000C higher than predicted by. The explanation for this phenomenon, scientists still have not found.



The well also confirmed the view of the device in the likeness of the crust layer cake - first sedimentary rocks, then granite, basalt and below. However, according to the drillers, granites were on the 3 km lower than expected, scientists. A basalt layer generally absent - 6 kilometers penetrated only through the granite. Scientists believe that the Kola drillers, without realizing it, have done Extremely open to all mankind.

Kola ultradeep borehole researchers presented another surprise: life on Earth originated, it appears, at 1.5 billion years earlier than expected. At depths where it was thought that there was no organic matter, found 14 species of fossilized microorganisms, and in fact the age of the deep layers of greater than 2.8 billion years. But, most surprisingly, an even greater depths, where there is no sediment was found methane gas in large concentrations. This is completely and utterly destroyed the theory of biological origin, hydrocarbons such as oil and gas.

On the Kola borehole have also been linked not only scientific sensation, but the mysterious legends, most of which turned out to be journalists when checking fiction. According to one of them (the birth of the author reports a Finnish newspaper), in the very thick of the earth at a depth of more than 12,000 meters, microphones, scientists recorded the cries and moans.


Journalists do not even thinking about that stick to such a depth mic just is not possible (which record the device can operate at a temperature of over two hundred degrees?) Wrote about the fact that the drillers had heard ' a voice from hell '. After these publications, the Kola super-deep well was called ' the road to hell ', arguing that every new kilometer drilled brought misfortune country.

They said that when the drillers were driving of thirteen thousand feet, the Soviet Union collapsed. Well, when the well was drilled to a depth of 14.5 km (which actually happened ), he suddenly came upon a strange emptiness. Intrigued by this unexpected discovery, the drillers went down a microphone, capable of operating at extremely high temperatures, and other sensors. The temperature inside the supposedly reached 1,100 ° C - a fiery heat of the chambers in which, supposedly, you could hear the cries of men.


This legend still roams the vast expanses of the Internet, having gone through the very culprit of gossip - the Kola borehole. Work on it stopped in 1992 due to lack of funding. Until 2008 it was in caretaker status. Two years ago, it was finally decided to abandon further research and to dismantle the entire research and development complex, but well - ' bury '. Final disposition of the well occurred this summer.

So, as you can see, this time scientists could not get to the mantle and to investigate its. However, this does not mean that the Kola borehole did not let science - on the contrary, she turned all of their ideas about the structure of the crust. Perhaps to get even deeper researchers will present the current oil well Maersk Oil ( 12 290 meters deep - which is 28 meters deep Kola ), which is located in the oil basin of the Al- Shaheen, Qatar.

Photovoltaics for the hospital

In the hospital in Mariupol install solar panels. From now on Baby Mariupol sun will warm the whole year round, without a break for the winter. This ensures that started in the operation of solar cell. Solar Energy supports the necessary heat in the hospital, warm water, dry diapers.

Experts say that such a unique setting in the Ukraine there is no. The cost of the work amounted to $ 80 thousand. And will pay for the installation of 3 - 3.5 years. For the suppression of acts of vandalism, the new unit is connected to the alarm system. The following year, the city intends to equip solar panels all health facilities.

Oracle SPARC Supercluster: a new record for database performance

Oracle. on the SPARC Supercluster is capable of producing 30 million database operations per minute, which is three times more than the previous record belonging to the software IBM DB2 and cluster P7. At the heart of SPARC Supercluster is 108 processor SPARC T3, and the total number of cores was 1728 pieces. The system has 13 terabytes of memory, 246 terabytes of flash memory and 1.7 petabytes of total disk space. Mr. Allison enthusiastically told the press on the achievement of the company.

Larry Ellison said that IBM is its real competitor with great potential, but the transition to Oracle on Sun SPARC processors are brought to the market leaders. He stated that the ratio of price and performance Supercluster at 27 percent better than the same. the IBM. Overall, Ellison spoke respectfully about IBM, can not be said about HP. He called the high-performance solutions HP ' turtles ' - a slow and vulnerable. Benchmark Oracle says Supercluster provides a 66 percent better price performance than the HP. HP Open criticism from Ellison's growing from month to month, so his remarks during the presentation of no surprise. Oracle has gained access to technology and Solaris SPARC after the absorption of the Sun. Many projects have been closed Sun Oracle, which has aggressively and tough management. But Oracle has found application server business to Sun. Mr. Ellison said that Oracle wants to be the Apple of the server market, providing customers with a fully integrated product: software and hardware, as well as full technical support and network services.

As part of this philosophy, Oracle introduced a new level of support, called Gold Standard Service, which completely covers all the technical questions about a product. Ellison said that Oracle wants to provide consumers with solid solutions, but will give them the right to choose. The company provides Gold Standard Service for products that combine the Oracle and other vendors. Allison noted the importance of the Linux operating system for business software Oracle, stating that Solaris does not become a barrier to the spread of Red Hat -based Linux distribution. Larry Ellison told about the Solaris Operating System 11, which will support new features and optimized virtualization. He also supported the introduction of solid-state drives tend to say that flash memory will speed up the processing of database. Oracle does not intend to rest on our laurels and will continue to implement solid-state drives into its server products. It is difficult to accept or deny the statements regarding the level of Oracle system performance Supercluster, since external independent tests were conducted, but on paper the results look really impressive. It seems that the influence on the world market and the financial resources of Oracle technology will bring Sun SPARC and Solaris to a new level.
