Tbilisi
–
Tbilisi, commonly known by its former name Tiflis, is the capital and the largest city of Georgia, lying on the banks of the Kura River with a population of roughly 1.5 million inhabitants. Founded in the 5th century by the monarch of Georgias ancient precursor the Kingdom of Iberia, Tbilisi has since served, with intermissions, as the capital of various Georgian kingdoms and republics. Under Russian rule, from 1801 to 1917 Tiflis was the seat of the Imperial Viceroy governing both sides of the entire Caucasus. Tbilisis varied history is reflected in its architecture, which is a mix of medieval, classical, Middle Eastern, Art Nouveau, historically, Tbilisi has been home to people of diverse cultural, ethnic, and religious backgrounds, though it is overwhelmingly Eastern Orthodox Christian. Archaeological studies of the region have indicated human settlement in the territory of Tbilisi as early as the 4th millennium BC, according to an old legend, the present-day territory of Tbilisi was covered by forests as late as 458. One widely accepted variant of the legend of Tbilisis founding states that King Vakhtang I Gorgasali of Georgia went hunting in the wooded region with a falcon. The Kings falcon allegedly caught or injured a pheasant during the hunt, King Vakhtang became so impressed with the hot springs that he decided to cut down the forest and build a city on the location. The name Tbilisi derives from Old Georgian Tbilisi, and further from Tpili, the name Tbili or Tbilisi was therefore given to the city because of the areas numerous sulphuric hot springs that came out of the ground. King Dachi I Ujarmeli, who was the successor of Vakhtang I Gorgasali, Tbilisi was not the capital of a unified Georgian state at that time and did not include the territory of Colchis. It was, however, the city of Eastern Georgia/Iberia. During his reign, King Dachi I oversaw the construction of the wall that lined the citys new boundaries. From the 6th century, Tbilisi grew at a steady pace due to the favourable and strategic location which placed the city along important trade. Tbilisis favourable and strategic location did not necessarily bode well for its existence as Eastern Georgias/Iberias capital, in the year 627, Tbilisi was sacked by the Byzantine/Khazar armies and later, in 736–738, Arab armies entered the town under Marwan II Ibn-Muhammad. After this point, the Arabs established an emirate centered in Tbilisi, in 764, Tbilisi, still under Arab control was once again sacked by the Khazars. In 853, the armies of Arab leader Bugha Al-Turki invaded Tbilisi in order to enforce its return to Abbasid allegiance, the Arab domination of Tbilisi continued until about 1050. In 1068, the city was again sacked, only this time by the Seljuk Turks under Sultan Alp Arslan. In 1122, after fighting with the Seljuks that involved at least 60,000 Georgians and up to 300,000 Turks. After the battles for Tbilisi concluded, David moved his residence from Kutaisi to Tbilisi, making it the capital of a unified Georgian State, from 12–13th centuries, Tbilisi became a dominant regional power with a thriving economy and a well-established social system/structure

Georgia (country)
–
Georgia is a country in the Caucasus region of Eurasia. The capital and largest city is Tbilisi, Georgia covers a territory of 69,700 square kilometres, and its 2016 population is about 3.72 million. Georgia is a unitary, semi-presidential republic, with the government elected through a representative democracy, during the classical era, several independent kingdoms became established in what is now Georgia. The kingdoms of Colchis and Iberia adopted Christianity in the early 4th century, a unified Kingdom of Georgia reached the peak of its political and economic strength during the reign of King David IV and Queen Tamar in the 12th and early 13th centuries. Thereafter the kingdom declined and eventually disintegrated under hegemony of various powers, including the Mongols, the Ottoman Empire. Russian rule over Georgia was eventually acknowledged in various treaties with Iran. Since the establishment of the modern Georgian republic in April 1991, post-communist Georgia suffered from civil, the countrys Western orientation soon led to the worsening of relations with Russia, culminating in the brief Russo-Georgian War in August 2008. Georgia is a member of the United Nations, the Council of Europe, and it contains two de facto independent regions, Abkhazia and South Ossetia, which gained limited international recognition after the 2008 Russo-Georgian War. Georgia and a part of the international community consider the regions to be part of Georgias sovereign territory under Russian military occupation. Georgia probably stems from the Persian designation of the Georgians – gurğān, in the 11th and 12th centuries adapted via Syriac gurz-ān/gurz-iyān, starting with the Persian word gurğ/gurğān, the word was later adopted in numerous other languages, including Slavic and West European languages. This term itself might have established through the ancient Iranian appellation of the near-Caspian region. The self-designation used by ethnic Georgians is Kartvelebi, the medieval Georgian Chronicles present an eponymous ancestor of the Kartvelians, Kartlos, a great-grandson of Japheth. However, scholars agree that the word is derived from the Karts, the name Sakartvelo consists of two parts. Its root, kartvel-i, specifies an inhabitant of the core central-eastern Georgian region of Kartli, ancient Greeks and Romans referred to early western Georgians as Colchians and eastern Georgians as Iberians. Today the full, official name of the country is Georgia, before the 1995 constitution came into force the countrys name was the Republic of Georgia. The territory of modern-day Georgia was inhabited by Homo erectus since the Paleolithic Era, the proto-Georgian tribes first appear in written history in the 12th century BC. The earliest evidence of wine to date has found in Georgia. In fact, early metallurgy started in Georgia during the 6th millennium BC, the classical period saw the rise of a number of early Georgian states, the principal of which was Colchis in the west and Iberia in the east

Tower
–
A tower is a tall structure, taller than it is wide, often by a significant margin. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, Towers are specifically distinguished from buildings in that they are not built to be habitable but to serve other functions. Towers can be stand alone structures or be supported by adjacent buildings or can be a feature on top of a structure or building. Old English torr is from Latin turris via Old French tor, the Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean language, connected with the Illyrian toponym Βου-δοργίς. The oldest known may be the stone tower in walls of Neolithic Jericho. Some of the earliest towers were ziggurats, which existed in Sumerian architecture since the 4th millennium BC, the most famous ziggurats include the Sumerian Ziggurat of Ur, built the 3rd millennium BC, and the Etemenanki, one of the most famous examples of Babylonian architecture. The latter was built in Babylon during the 2nd millennium BC and was considered the tallest tower of the ancient world, some of the earliest surviving examples are the broch structures in northern Scotland, which are conical towerhouses. These and other examples from Phoenician and Roman cultures emphasised the use of a tower in fortification, for example, the name of the Moroccan city of Mogador, founded in the first millennium BC, is derived from the Phoenician word for watchtower. The Romans utilised octagonal towers as elements of Diocletians Palace in Croatia, which monument dates to approximately 300 AD, while the Servian Walls, the Chinese used towers as integrated elements of the Great Wall of China in 210 BC during the Qin Dynasty. Towers were also an important element of castles, other well known towers include the Leaning Tower of Pisa in Pisa, Italy built from 1173 until 1372 and the Two Towers in Bologna, Italy built from 1109 until 1119. The Himalayan Towers are stone towers located chiefly in Tibet built approximately 14th to 15th century, up to a certain height, a tower can be made with the supporting structure with parallel sides. However, above a height, the compressive load of the material is exceeded. This can be avoided if the support structure tapers up the building. A second limit is that of buckling—the structure requires sufficient stiffness to avoid breaking under the loads it faces, many very tall towers have their support structures at the periphery of the building, which greatly increases the overall stiffness. A third limit is dynamic, a tower is subject to varying winds, vortex shedding and these are often dealt with through a combination of simple strength and stiffness, as well as in some cases tuned mass dampers to damp out movements. Varying or tapering the outer aspect of the tower with height avoids vibrations due to vortex shedding occurring along the building simultaneously. Although not correctly called towers many modern skyscraper are often called towers, in the United Kingdom, tall domestic buildings are referred to as tower blocks. In the United States, the original World Trade Center had the nickname the Twin Towers, the tower throughout history has provided its users with an advantage in surveying defensive positions and obtaining a better view of the surrounding areas, including battlefields

Gori, Georgia
–
Gori is a city in eastern Georgia, which serves as the regional capital of Shida Kartli and the centre of the homonymous administrative district. The name is from Georgian gora, that is, heap, Gori was an important military stronghold in the Middle Ages and maintains a strategic importance due to its location on the principal highway connecting eastern and western parts of Georgia. In the course of its history, Gori has been invaded by the armies of regional powers several times, the city was occupied by Russian troops during the 2008 Russia–Georgia war. Gori is also known as the birthplace of the Soviet leader Joseph Stalin, ballistic missile designer Alexander Nadiradze, Gori is located 86 kilometers west of Georgias capital Tbilisi, at the confluence of the rivers Mtkvari and Greater Liakhvi,588 meters above sea level. The climate is transitional from moderately warm steppe to moderately humid, the average annual temperature is 10.6 °C, minimal in January and maximal in July and August. The maximum precipitation falls in May and minimum in February, the territory of Gori has been populated since the early Bronze Age. According to medieval Georgian chronicles, the town of Gori was founded by King David IV who settled refugees from Armenia there. However, the fortress of Gori appears to have been in use already in the 7th century, in 1299, Gori was captured by the Alan tribesmen fleeing the Mongol conquest of their original homeland in the North Caucasus. The Georgian king George V recovered the town in 1320, pushing the Alans back over the Caucasus mountains and it was first taken and sacked by Uzun Hassan of the Ak Koyunlu in 1477, followed by Tahmasp I of Persia in the mid-16th century. The town was again garrisoned by the Persians under Shah Abbas I in 1614. Following the Russian annexation of Georgia, Gori was granted the status of a town within the Tiflis Governorate in 1801 and it grew in size and population throughout the 19th century but was destroyed in the 1920 earthquake. An important industrial center in Soviet times, Gori suffered from an economic collapse, Gori is close to the Georgian-Ossetian conflict zone. It is connected to breakaway South Ossetias capital Tskhinvali via a spur which has been defunct since the early 1990s. Since the 2000s, Georgia has increased the military infrastructure in, thus, the Central Military Hospital was relocated from Tbilisi to Gori and re-equipped in October 2006. On January 18,2008, Georgia’s second NATO-standard base to accommodate the 1st Infantry Brigade of the Georgian Ground Forces was established at Gori, the Georgian Agrarian Science Academy Branch was established in the city in 1995, this became Sukhishvili University in 2003. Human Rights Watch claimed that Russian forces had indiscriminately deployed cluster bombs in areas around Gori. According to HRW, on August 12 Russian forces dropped bombs in the center of Gori, killing 11 civilians. Russian military officials deny using cluster munitions in the conflict, calling the HRW assertion slanderous, numerous unexploded bomblets have been found by locals and HRW employees

Radio masts and towers
–
Radio masts and towers are, typically, tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two types, guyed and self supporting structures. They are among the tallest man-made structures, masts are often named after the broadcasting organizations that originally built them or currently use them. In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna, the terms mast and tower are often used interchangeably. However, in engineering terms, a tower is a self-supporting or cantilevered structure. Broadcast engineers in the UK use the same terminology, in US broadcast engineering, a tower is an antenna structure attached to the ground, whereas a mast is a vertical antenna support mounted on some other structure. Masts tend to be cheaper to build but require an extended area surrounding them to accommodate the guy wires, Towers are more commonly used in cities where land is in short supply. There are a few designs that are partly free-standing and partly guyed, called additionally guyed towers. For example, The Gerbrandy tower consists of a tower with a guyed mast on top. The few remaining Blaw-Knox towers do the opposite, they have a lower section surmounted by a freestanding part. Until August 8,1991, the Warsaw radio mast was the worlds tallest supported structure on land, there are over 50 radio structures in the United States that are 600 m or taller. The steel lattice is the most widespread form of construction and it provides great strength, low weight and wind resistance, and economy in the use of materials. Lattices of triangular cross-section are most common, and square lattices are also widely used, guyed masts are often used, the supporting guy lines carry lateral forces such as wind loads, allowing the mast to be very narrow and simply constructed. When built as a tower, the structure may be parallel-sided or taper over part or all of its height, when constructed of several sections which taper exponentially with height, in the manner of the Eiffel Tower, the tower is said to be an Eiffelized one. The Crystal Palace tower in London is an example, guyed masts are sometimes also constructed out of steel tubes. This construction type has the advantage that cables and other components can be protected from weather inside the tube and these masts are mainly used for FM-/TV-broadcasting, but sometimes also as mast radiator. The big mast of Mühlacker transmitting station is an example of this. A disadvantage of this mast type is that it is more affected by winds than masts with open bodies

Wayback Machine
–
The Internet Archive launched the Wayback Machine in October 2001. It was set up by Brewster Kahle and Bruce Gilliat, and is maintained with content from Alexa Internet, the service enables users to see archived versions of web pages across time, which the archive calls a three dimensional index. Since 1996, the Wayback Machine has been archiving cached pages of websites onto its large cluster of Linux nodes and it revisits sites every few weeks or months and archives a new version. Sites can also be captured on the fly by visitors who enter the sites URL into a search box, the intent is to capture and archive content that otherwise would be lost whenever a site is changed or closed down. The overall vision of the machines creators is to archive the entire Internet, the name Wayback Machine was chosen as a reference to the WABAC machine, a time-traveling device used by the characters Mr. Peabody and Sherman in The Rocky and Bullwinkle Show, an animated cartoon. These crawlers also respect the robots exclusion standard for websites whose owners opt for them not to appear in search results or be cached, to overcome inconsistencies in partially cached websites, Archive-It. Information had been kept on digital tape for five years, with Kahle occasionally allowing researchers, when the archive reached its fifth anniversary, it was unveiled and opened to the public in a ceremony at the University of California, Berkeley. Snapshots usually become more than six months after they are archived or, in some cases, even later. The frequency of snapshots is variable, so not all tracked website updates are recorded, Sometimes there are intervals of several weeks or years between snapshots. After August 2008 sites had to be listed on the Open Directory in order to be included. As of 2009, the Wayback Machine contained approximately three petabytes of data and was growing at a rate of 100 terabytes each month, the growth rate reported in 2003 was 12 terabytes/month, the data is stored on PetaBox rack systems manufactured by Capricorn Technologies. In 2009, the Internet Archive migrated its customized storage architecture to Sun Open Storage, in 2011 a new, improved version of the Wayback Machine, with an updated interface and fresher index of archived content, was made available for public testing. The index driving the classic Wayback Machine only has a bit of material past 2008. In January 2013, the company announced a ground-breaking milestone of 240 billion URLs, in October 2013, the company announced the Save a Page feature which allows any Internet user to archive the contents of a URL. This became a threat of abuse by the service for hosting malicious binaries, as of December 2014, the Wayback Machine contained almost nine petabytes of data and was growing at a rate of about 20 terabytes each week. Between October 2013 and March 2015 the websites global Alexa rank changed from 162 to 208, in a 2009 case, Netbula, LLC v. Chordiant Software Inc. defendant Chordiant filed a motion to compel Netbula to disable the robots. Netbula objected to the motion on the ground that defendants were asking to alter Netbulas website, in an October 2004 case, Telewizja Polska USA, Inc. v. Echostar Satellite, No.02 C3293,65 Fed. 673, a litigant attempted to use the Wayback Machine archives as a source of admissible evidence, Telewizja Polska is the provider of TVP Polonia and EchoStar operates the Dish Network
