Providers of the Russian Federation, for the most part, use the systems of deep traffic analysis (DPI, Deep Packet Inspection) to block sites included in the register of banned. There is no single standard for DPI, there is a large number of implementations from different DPI providers that differ in the type of connection and type of work.

There are two common types of DPI connection: passive and active.
Passive DPI
Passive DPI-DPI connected to the provider network in parallel (not in the section) either through a passive optical splitter or using the mirroring of user traffic. This connection does not slow down the speed of the network provider in the case of insufficient DPI performance, which is why it is used by large providers. DPI with this type of connection can technically only detect an attempt to query for prohibited content, but not to suppress it. To circumvent this restriction and block access to the denied site, DPI sends a specially crafted HTTP packet to the user requesting the blocked URL, redirecting to the stub page of the provider, as if the requested resource itself had been sent by the user (the IP address of the sender and the TCP sequence are forged). Because the DPI is physically located closer to the user than the requested site, the forged response reaches the user's device faster than the real response from the site.

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.
