What is an intranet?

This term is used by IT professionals often enough, but not always correctly interpreted by users. So it makes sense to discuss it.

Under the intranet is usually understood to a local area network (detailed, for example, within an organization), based on the same technical solutions as the "big" Internet, that is, based on the IP-protocols. In their own corporate intranet contains information resources - corporate portal, corporate forum, corporate bulletin board, etc. They are implemented in such a way as to be accessible only to internal users (employees of the organization), but are accessed using a conventional browser.

It is worth noting that although the above at all times referred to the intranet as a corporate network, in practice this internal network can exist not only in organizations but also, say, in the dormitories or in private homes. And absolutely not necessary that the intranet was organized in some sort of separate geographically localized place - through the use of a VPN (Virtual Private Networks, VPN) access to intranet resources can receive and those who live overseas.

Naturally, the resources available for HTTP/HTTPS, - are not the only services that are used in the intranet. Also, users with "a reduced copy of the Internet" is usually available internal e-mail (SMTP and POP3/IMAP), the internal file servers (FTP), and in many cases operating under the corporate network instant messenger, VoIP-system.

Intranet services are simply convenient for work, so today and got a very widespread practice around the world. Current Intranet solutions allow organizations using them to save on their implementation by eliminating the need to install additional software on client workstations staff, and, moreover, intranet services rather convenient in cases when users are working under different operating systems, as an intranet technologies are inherently cross-platform. Of course, the intranet itself needs serious protection from unauthorized external access, as well as some additional effort on the part of system administrators, but it's all be more than compensated the advantages that it offers.

News For Developers - 10

Microsoft has released an updated version of its subsidiary set of developer tools called Visual Studio 2010 Productivity Power Tools. Among the main differences between the new version should be noted the new ability to selectively disable individual add-ins and Solution Navigator tool for easy navigation of code complex multicomponent solutions. Now users of Visual Studio 2010 have the discretion to enable and disable add-ins. Besides, now all options for add-ins are configured through a single dialog. Utility Solution Navigator provides the user with the support dialogue, which operates in the same way as a more powerful tool Solution Explorer, designed for professional project management in software development. Community Center Solution Navigator can easily deploy the files with the code for easy transition to fit classes, as well as quickly find members of the classes within the class you want. Solution Navigator also offers users a search by code, the filtering project, view information about the classes, as well as preview images. Compared with Service Solution Explorer, the utility lacks only the simultaneous selection of several objects and drag elements. The new Quick Access to a set of Productivity Power Tools offers users a tool box for finding and executing the most popular teams integrated development environment. Function Automatic Brace Completion (automatic closing brackets) improves productivity when writing code by automatically inserting closing code constructions, when opening constructions for typed languages, Visual Basic or C #. In addition, the new version of Productivity Power Tools contains fixes for tools from the previous version, for example, the corrected function Searchable Add Reference (adding links, indexed for searching), and color highlighting in the Help options. In addition, the function is now supported by cutting and copying the code in HTML.

One of the leading engineers of Google - Rob Pike - spoke at a conference O'Reilly Open Source Convention (OSCON) and believed the corporation of modern languages and the development site C + + and Java on them, according to the same source. Pike said about these industrial whales very negatively, describing them as wordy, overly complex and inappropriate for use in solving problems of modern computing infrastructure. "I think that these languages are too complicated to use, too difficult to understand, too complicated. They are very wordy, their complexity, the complexity and incomprehensibility increases with time", - said Rob.

According to the same source, was released PHP 5.3.3, which includes official support for PHP-FPM (FastCGI Process Manager SAPI) and a large number of bug fixes (the result of the action "Month of PHP Security"). The inclusion in the mainline patches from opens up prospects for widespread alternative to apache + mod_php5 decisions - such combinations as nginx + php-fpm or lighttpd + php-fpm, allowing for better performance of Web applications.

Virtualization Reality

If ten years ago you told someone that he could be put behind bars because of the comments on a blog or post on the forum, people would laugh at you and walked away. Today, it is no longer funny - than, as they say, farther into the forest, the more cyber space penetrates all our lives and the more potential trouble can bring such penetration...

In fact, more than logical. The Internet has become a very important part of society, which is already being called the post-industrial, and most important resource in this society is no longer gold and even oil, and information. But property information such that it can not sell its weight ", as sold at traffic megabytes ISPs. The cost of one megabyte of information can vary from zero (when the megabyte - a meaningless "noise" or simply "zeros") to almost infinity (eg, per megabyte which some secret information to the Pentagon). And for a society where information is not just an important commodity, and perhaps most important, treat her with respect, or, indeed, even with awe, quite naturally. And if someone earns in the sale of information, it is natural that he would use all its capabilities to deal with those who receive this information free of charge - which, strictly speaking, and make the holders the rights to music and movies.

As the Internet today is much more populous place than it was ten years ago, it is logical and change the attitude of the authorities of most countries to the statements by the World Wide Web. If before throwing mud and not very well known citizens in the World Wide Web were rarely subject to public attention, but now thanks to the instantaneous response of the Internet community at virtually any network developments and trends to reduce the anonymity of each individual Internet user for his statements really have to follow more closely . Examples of what is really needed "to keep my ears open, becomes greater with each passing day - not just last week, the Moscow City Court upheld the decision on which blogger Michael Verbitsky must pay 40 thousand rubles for the trainer Yuri Kuklachev accusation of the use of electric shocks during dressing cats. And so this kind of litigation in the West and did not find.

What will happen next? It is possible that the day is near when the example of many European countries (including the not so distant from us in Estonia) for each inhabitant of our planet will be a plastic card - an electronic copy of his personality, giving him the right to literally all - of receive their money in the bank (and cash at the time was obviously not remain) to travel in public transport. And then there really will be a big headache that today, many experts predict security - identity theft. " Even today, having some idea of the state systems, create virtual people is no more difficult than virtual firms "phony", and to conduct on behalf of many operations. Further there will be even easier - apparently it is this is one of the main risks of further virtualization of the surrounding reality. However, as it will in fact, of course, only time will show...

In Russia are preparing a law on the Internet

July 5th State Duma deputy from the "United Russia" Robert Schlegel has published in his blog the text of the draft law on the internet. Rather, it is about 30 pages of amendments to the law "On information, information technology and information security. On July 7, had already been officially declared that the working group of the Duma committee on information policy, prepared a draft law regulating the use of the Internet in Russia.

Changes for the better

Duma amendments to the law "On information, information technology and information security for the first time in the history of Russian law-introduce such basic concepts as" global computer networks "and" operator of a web-site. " They also determine the limits of jurisdiction of national legislation on the World Wide Web. It is known that the Duma bill will be introduced no earlier than autumn, when he sent to the presidential administration and government.

The Working Group is predicated on Internet law, an initiative of United Russia. Its composition gives the hope that Russia will avoid the strict controls and restrictions on the web. Among the developers of the new version of the law - the secretary of the Union of Journalists of Russia Mikhail Fedotov (author of the current law on mass media), the head of the UNESCO Chair at the Higher School of Economics Astamur Tedeev, editor in chief of Moskovsky Komsomolets, Pavel Gusev, and "guru Runet Anton Nosik.

The main idea of legislative changes is as follows: in RuNet can do the same thing in real life. Made clear: any attempt to impose additional restrictions are illegal. Also, there should be no restrictions on the rights of Internet businesses and individuals out of court: any limitation is only with court approval. The bill states that: "The transfer of information through global computer networks with no restrictions - if it does not violate the law, and responsibility for the information it carries a direct distributor, but not the operator, providing access to the network."

In this business relationship in the web under the jurisdiction of Russian law, if their object is the property located on the territory of Russia, a party in such relationships are natural and legal persons - residents of Russia. Let me explain: if the owners of the site - the Russians, and their server - on foreign hosting, they still are responsible for your site.

However, Minkomsvyazi prepared an alternative bill - it is significantly expands the powers of police and security services when working with providers and web-sites and in many respects similar to the Belarusian Decree № 60. In particular, the document proposes that all ISPs and registrars to suspend domain name on the letter of the law enforcement agency and restrict user access to information in the web of the Prosecutor. However, as analysts have noticed, the de facto in RuNet these standards are already working.


Duma developers' law on the Internet "took care of that bill give users as much as possible the rights that previously had not been legislated. For this purpose, in particular, legislators changed the terms used in the previous version of the document - some concepts removed, while others have added. For example, given the improved definition of "information", the term "information-telecommunications network, replace" global computer network ", introduced the concept of the site operator and the operator access to the global network (ISP). True, and not a definition of the word "site".

Article 12, devoted to the basics of state regulation in the IT-field, now states that one purpose of government - ensuring its citizens unhindered access to information technologies and networks. Also, the State must ensure that the rights and lawful interests of users of the Internet and other computer technologies.

In this state regulation would be aimed at ensuring the inviolability of property, freedom and economic activity, and another to his will "expand the penetration of global computer networks in Russia."

Article 16 prohibits the public authorities to adopt "regulations, abolishing or restricting the rights of users and providers. Also, you can not enter non-law "On information" duties, prohibit access to the web and change the definitions which are contained in the law.

Article 18 introduces the concept of "information practices and netiquette." If such "custom" does not violate the law of Russia, then they are given to self-regulation to the Internet community.

The question of whether the provider and have hoster responsibility for the information disseminated by the user, is solved explicitly: "No, do not bear.

MPs expect a draft law that would support Dmitry Medvedev, is their version of the changes in the RF Law "On information, information technology and information security. At the same hopes, it seems, and an absolute majority runetchikov. But there are still many questions. For example, it is unclear how innovations are consistent with SORM system that allows intelligence agencies obtain information in the telecommunication network without notifying the court.


For the first time, Russian deputies tried to "regulate the Internet in 2000. Then the State Duma Committee on Information Policy attempted to hold public hearings on this issue and develop a bill acceptable to all. But the idea fell through - the cyber space, and Russian lawmakers have existed in different dimensions.

In 2008, experts Vladimir Gorzhaltsan and Yuri Temples presented their model law "On the Internet". The status of the model meant that the document - just a compilation of recommendations for the subjects of the federation, who want to do legislative regulation web. However, wary of any activity relating to the state in the network of Russian Internet community has adopted the document "in arms".

But now all in their stride - the same online community believed that the current Russian president, happen that did not give the Internet to insult.

Version now before the legislative changes, Mikhail Fedotov and Robert Schlegel, briefly described the journalists at the beginning of this year. Then they, in particular, have recognized that refused to clearly articulated standards of conduct in any given situation, but simply codified the basic principles of Runet.
