We hurry the general capacity of the LeaseWeb networks in a data-center of a premium class of EvoSwitch in which we offer dedicated servers in lease will share joyful news, in the 2015th year, reached value 5 of Tbit / page. It is a lot of or a little? Why over 60 000 subscribers selected this data-center for the projects in spite of the fact that exist more profitable at the offer price of low-costers in other countries? The reasons a set, in particular — we, a hosting provider which applies an individual approach to each subscriber, but nevertheless, in addition to us, it:
— loyal legislation of the Netherlands; — EvoSwitch premium class data-center; — LeaseWeb — provider with whom we and our subscribers successfully cooperate many years we are their bonus partners and thanks to long-term cooperation we can offer terms better, than in a data-center directly, at the same time in every possible way caring for you in an individual order (on a site the selected engineer is always available, requests of our subscribers are reviewed in priority, in 90% of cases technical support is given by our administrators far off without the need for carrying out physical works with the server); — a network of delivery of a traffic to your visitors with improbable connectivity (minimum a ping and maximum speed on a flow); — the general capacity of a network 5 of Tbit / with; — 2,5 Tbit / from a traffic are generated by subscribers of a data-center; — 58 points of presence worldwide; — inclusions in 36 points of an exchange of a traffic in more, than 20 countries; — 4213 peer-to-peer connections to Internet service providers of different level.

Opening of a new data-center of the British provider of a collocation of Hydro66 took place. All IT infrastructure of DPC of 1 000 sq.m. will work at the hydroelectric power from the nearest hydroelectric power station (500 m) which is near the Swedish city Boden. According to designers the similar choice of power sources will help to reduce costs for a collocation in comparison with platforms of Europe and Great Britain. Also it will turn out to reduce costs at the expense of a location. The climate of Sweden rather cold will also allow to refuse mechanical and chemical methods of cold supply.

In 1956 there was a need for creation of a practical sample of the digital computer which could be used in higher education institutions, laboratories. For such purposes the effective small computer expected mass use was required simple in mastering, reliable, inexpensive, but at the same time.
The requirements shown to such machine: speed of work had to be equal to several hundred operations per second, simplicity and convenience of programming, accuracy of calculations — 6-8 sure decimal signs, high-reliability in operation and in technical maintenance, moderate dimensions, economical consumption of energy, use of inexpensive and "not scarce" materials and parts "was welcomed". Such requirements for those times were "inconsistent", creation of the machine more convenient for work of programmers would cause increase in quantity of the equipment that, in turn, would entail decrease in reliability and value increase not only the machine, but also its operation.
In a case when a startup the project young and perspective, but the budget is strongly limited — it is necessary to squeeze out a maximum possible from the available resources. Well if money under an equipment upgrade is budgeted (in mythical good time), but now it is necessary to receive performance maximum from the available resources.
On open spaces of the Internet there are many articles on a subject as to implement it — failure from LAMP for benefit of nginx+php-fpm or uWSGI (out of need), their thin setup (we do not forget to cache a statics), the PHP installation of an accelerator, tuning of DBMS (if it is used), and other useful things.
But even at installation and competent execution of all points it is possible to optimize work of services a little more.

The address programming language is considered one of the first programming languages of the high level. It was created by the Soviet developer Ekaterina Logvinovna Yushchenko together with the mathematician Vladimir Semenovich Korolyuk in 1955. Constructions of this algorithmic language were included into a basis of the modern languages of programming.
Developments of the member of the correspondent of Academy of Sciences of the USSR Alexey Andreevich Lyapunov became a peculiar base for address language. This outstanding mathematician created the operator programming method which was widely adopted in practice and exerted strong impact on all subsequent development of theoretical programming.

— at payment of VPS/server for a period of the 1st month you receive a month more of use absolutely free of charge; — for a period of 6 months — 2 months as a gift; — of the 1st year — 3 months as a gift.
And all this despite magic discounts which still continue to work, in particular at annual payment! And they on truth of a volshebna, for example, it is possible to rent a dedicated server in the Netherlands of 2 x Intel Quad-Core Xeon 5504/16GB DDR3/12x500GB SATA/1Gbps 100TB only for $59,93 a month now! It is nearly 4 times cheaper than standard cost!

When you work in a hosting company most of friends and acquaintances, all the issues concerning a hosting are resolved through you. It allows to be in a trend of the last innovations, and also not only to increase the skills, but also to keep them in a tone. As soon as special problems of children became difficult to be solved on a hosting server, as a rule due to the lack of an opportunity to set necessary software for work of this or that script, I thought of the inexpensive virtual server at once, especially they at us appeared. Also we understood that it will be simpler to work with the server via the convenient web interface, and the good control bar will be as-@-as, by the way. And if it is also free, then we will be only in plus. Without hesitation, opened the browser and began to google free control bars a hosting.
Understanding that studying of everyone will demand time, I decided to ask also council our experienced administrator on what I received the short answer:
But the head of technical department allowed expect the answer enough:
These are not really popular in our circles.
Here so there was my first acquaintance to one of the most popular free control bars a hosting in a RuNet — Vesta CP. I would like to tell you as the solution of objectives leads not only to writing of tutorials, but also allows to get acquainted with interesting people who put the heart and soul in that business which are really brought to them by pleasure. And as a result, we receive the remarkable software product. Well unless it is not wonderful? Pleasant and constructive to you readings …

For these years I became the witness of how more and more people support the manifesto 12 Factor App and begin to implement the provisions described there. It led to emergence of applications which were considerably simplified in expansion and management. However examples of practical application of these 12 factors were quite unusual occurrence on Internet open spaces.
During operating time with Docker, benefits of 12 Factor App (12FA) of steel for me more notable. For example, 12FA recommends that logging was configured for standard output and it was processed as the general event stream. You sometime used command docker logs? It also is 12FA in operation!
Data leakage of users of different services because of cracking of the last — not a rarity, unfortunately. It is worth remembering sensational cracking of service of changes of Ashley Medison when in the Network data of millions of users flowed away. A huge number of users were just bots, but it changes nothing — each of us is vulnerable.
In the Network even data of users who monitor the accounts flow away, think out difficult passwords, try to provide negative scenarios. But leaks all the same happen. And interesting nuance — if about data security of adults all monitor and everywhere, then a problem of data protection of children in the Network somehow not too very famous. And here it is even more problems, children are not too well acquainted with bases of information security. And if yes, that hackers find other ways of data acquisition of kids. It is possible to give recent cracking of the VTech services (the vendor of children's electronic toys) as a result of which in the Network data of millions of accounts of little users flowed away as an example.
