English Part News of the Cyberspace
Hello!
My name is Alexander Gritsunov. I live in Kharkiv (Ukraine). Welcome to my Site!

This Site is the main part of my Cyberspace. A Library, a Gallery and an Archive are other parts of the Cyberspace. The Cyberspace consists of a cluster of paid second-level Platinum domains and a cluster of free third-level Silver domains. There is also a cluster of unused at present third-level Standby domains

You can enter to the Cyberspace via the equivalent initial pages: However, you must remember that "Front page news" I present only on the first initial page from the listed above (except for "News of the Cyberspace" referred in the upper right corner of this page). So, always try enter to the Cyberspace through http://gritsunov.com
Logical Organization of the Site

The Site has a hierarchical tree logical structure. On the highest (zero) level, the initial page is placed. This is not a "home page" in the ordinary sense (i.e., as some "refuge" where one can jump from any point of the Site). There is no need to do that at all. This Site is logically organised on the principle: "My home is where I reside now". The Navigation tiling™ allows you always to watch all the levels you already have passed and to jump to a wanted page directly or, at least, bypassing the initial page. The current (active) tile is tinted with blue and pushed down. Passed tiles are in steelblue, inactive ones are in slate. Thus, the initial page is nothing more than an entry point to the Site.

On the first level, the Site parts are placed. Each the part embodies one language. Three languages are implemented now: English, Russian, and Ukrainian.

Independently of the language, the second level consists of five sections: "My personality", "Scientific work", "Educational work", "My leisure", and "Et cetera". These are divided into subsections (the third level) and so on. For the sake of simplicity, any element of the hierarchical logical structure placed below a section is called as subsection.

Each page of the Site consists of the main sheet (left, white) and the side sheet (right, sky-blue). As it follows from these names, the main sheet maintains the paramount information, the side sheet presents complementary data. The main sheet can also include blue insets containing complementary information.

The Site is illustrated with the photos of unified dimensions of 320×240, 240×180, 160×120 or 120×90 pixels. Click any photo to enlarge it up to the size of 1024×768, 800×600, 640×480 pixels or another.

There may be points in the Site hierarchical tree logical structure where more than five branches must arise from. Because the Navigation Tiling™ panel unable containing too many tiles in a row, the standard Site structure breaks in such points and non-standard pages originate. Those are treated as "pages-extensions" of a generating primary standard page (parent page). Links to pages-extensions are placed on the primary page main sheet, not on the Navigation Tiling™ panels, so number of those may be as much as needs. A higher standard logical structure is "frozen" for all pages-extensions. A tile of the parent primary page stays highlighted in magenta on all those pages-extensions. See example of page-extension.

So-called popup window is a particular case of the page-extension. This window has smaller size and does not contain the Site header, the Navigation Tiling™ panels as well as the side sheet. The popup windows are used for successive concretizing the information of a primary page or a page-extension, as a rule. See example of popup window.

To make easier the navigation over the Site logical structure, each page, both primary and extension, has its own unique number, placed in the upper left corner of the main sheet. For a primary page, this is a digital number where each cipher (from 1 to 5) is the active or passed tile position in the respective row of the Navigation Tiling™. For a page-extension, the number consists of the digital number of the parent primary page and chain from one to the current page using mnemonic names of html/php files. Slash means transition to a subdirectory (index.html or index.php initial file name in subdirectory is omitted), hyphen signifies link to another html/php file within the current directory. All popup windows have the same mnemonic name "Popup".

The main format of the downloadable documents for this Site is PDF (Portable Document Format). This is a universal file format that preserves the fonts, images, and layout of source documents created on a wide range of applications and platforms. PDF is the standard for the secure, reliable distribution and exchange of electronic documents and forms around the world. Adobe PDF files are compact and complete, and can be shared, viewed, and printed by anyone with free Adobe® Reader® software. You can download the latest version of Adobe® Reader® from the Adobe Reader page.

An alternative format of the documents is DjVu (pronounced "deja vu"). This is a digital document format with advanced compression technology and high performance value. DjVu can advantageously replace PDF, PS, TIFF, JPEG, and GIF for distributing scanned documents, digital documents, or high-resolution pictures. DjVu content downloads and renders faster, looks nicer on a screen, and consume less client resources than competing formats. DjVu images display instantly and can be smoothly zoomed and panned with no lengthy re-rendering. DjVu viewers are available on DjVuLibre page. A free WinDjView is especially recommended, if suitable for your OS.

The upper and the lower Navigation Tiling™ panels are identical while the Site works normally. However, it is recommended to try the both panels, if a trouble will appear or if you wait for a new information (see "Physical Organization of the Cyberspace" article in the right part of this page to learn more).

Notice for the visitors from European countries and Russia. The upper and lower domains of the Platinum Site, as well as the Silver Site, share the server resources with users from the USA. Therefore, attempt working with the regional (Russian or Ukrainian) domains in the evening, if possibly.

Physical Organization of the Cyberspace

The physical resources of this Cyberspace are distributed over several hosts. Such organization gives, in particular, better persistence. If one of the hosts should stop service, it will be possible to relocate the lost resources, so that users will observe no changes in the Cyberspace logical structure. A visitor will be able to enter to the Cyberspace via surviving initial pages:

and to follow over the unchanged Navigation Tiling™. If all the hosts are in good order, the abovementioned initial pages are identical.

All resources of the Platinum Site are duplicated on two hosts: "upper" and "lower" (according to the location of the Navigation Tiling™ panels referring to those hosts). This is so-called twinned hosting. The contents of both the hosts are kept up similar as far as possible in the normal state. However, it will be advisable to try both the hosts by clicking the necessary tile in both the upper and the lower panels in turn, if any trouble arise. For the regional domains, as well as the Silver Site, the twinned hosting has not built up. So, the upper and the lower panels point on the same host.

Warning. You must enter to the Cyberspace only via one of the valid initial pages listed above to obtain all advantages of the Cyberspace logical structure independence from the physical structure of one.
