Unicode
Unicode or ''The Unicode Standard'' or TUS is a character encoding standard maintained by the Unicode Consortium designed to support the use of text in all of the world's writing systems that can be digitized. Version 16.0 defines 154,998 Character (computing), characters and 168 script (Unicode), scripts used in various ordinary, literary, academic, and technical contexts. Unicode has largely supplanted the previous environment of a myriad of incompatible character sets used within different locales and on different computer architectures. The entire repertoire of these sets, plus many additional characters, were merged into the single Unicode set. Unicode is used to encode the vast majority of text on the Internet, including most web pages, and relevant Unicode support has become a common consideration in contemporary software development. Unicode is ultimately capable of encoding more than 1.1 million characters. The Unicode character repertoire is synchronized with Univers ...

Linear A
Linear A is a writing system that was used by the Minoans of Crete from 1800 BC to 1450 BC. Linear A was the primary script used in Minoan palaces, palace and religious writings of the Minoan civilization. It evolved into Linear B, which was used by the Mycenaean civilization, Mycenaeans to write an early form of Ancient Greek, Greek. It was discovered by the archaeologist Sir Arthur Evans in 1900. No texts in Linear A have yet been Undeciphered writing systems, deciphered. Evans named the script "Linear" because its characters consisted simply of lines inscribed in clay, in contrast to the more pictographic characters in Cretan hieroglyphs – likewise undeciphered – that were used during the same period. Linear A belongs to a group of scripts that evolved independently of the Egyptian and Mesopotamian systems. During the second millennium BC, there were four major branches: Linear A, Linear B, Cypro-Minoan, and Cretan hieroglyphs, Cretan hieroglyphic. In the ...

Screw Head - Pozidrive
A screw is an externally helical threaded fastener capable of being tightened or released by a twisting force (torque) to the head. The most common uses of screws are to hold objects together and there are many forms for a variety of materials. Screws might be inserted into holes in assembled parts or a screw may form its own thread. The difference between a screw and a bolt is that the latter is designed to be tightened or released by torquing a nut. The screw head on one end has a slot or other feature that commonly requires a tool to transfer the twisting force. Common tools for driving screws include screwdrivers, wrenches, coins and hex keys. The head is usually larger than the body, which provides a ''bearing surface'' and keeps the screw from being driven deeper than its length; an exception being the ''set screw'' (aka grub screw). The cylindrical portion of the screw from the underside of the head to the tip is called the ''shank''; it may be fully or partially ...

List Of Screw Drives
At a minimum, a screw drive is a set of shaped cavities and protrusions on the screw head that allows torque to be applied to it. Usually, it also involves a mating tool, such as a screwdriver, that is used to turn it. Some of the less-common drives are classified as being "tamper-resistant". Most heads come in a range of sizes, typically distinguished by a number, such as "Phillips #00". Overview Slotted drives Slot Slot screw drives have a single horizontal indentation (the ''slot'') in the fastener head and is driven by a "common blade" or flat-bladed screwdriver. This form was the first type of screw drive to be developed, and, for centuries, it was the simplest and cheapest to make because it can just be sawed or filed. Blunt or damaged tools can easily be re-ground as required in any workshop. It is unique because the slot head is straightforward to manufacture, and because it can be driven by a simple handtool. The ''slotted screw'' is commonly found in existing p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zodiac Killer Symbol
The zodiac is a belt-shaped region of the sky that extends approximately 8° north and south celestial latitude of the ecliptic – the apparent path of the Sun across the celestial sphere over the course of the year. Within this zodiac belt appear the Moon and the brightest planets, along their orbital planes. The zodiac is divided along the ecliptic into 12 equal parts, called " signs", each occupying 30° of celestial longitude. These signs roughly correspond to the astronomical constellations with the following modern names: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. The signs have been used to determine the time of the year by identifying each sign with the days of the year the Sun is in the respective sign. In Western astrology, and formerly astronomy, the time of each sign is associated with different attributes. The zodiacal system and its angular measurement in 360 sexagesimal degree (°) origi ...

Zodiac Killer
The Zodiac Killer is the pseudonym of an unidentified serial killer who murdered five known victims in the San Francisco Bay Area between December 1968 and October 1969. The case has been described as "arguably the most famous unsolved murder case in American history," and has become both a fixture of popular culture and a focus for efforts by amateur detectives. The Zodiac's known attacks took place in Benicia, Vallejo, unincorporated Napa County, and the City and County of San Francisco proper. He attacked three young couples and a lone male cab driver. Two of these victims survived. The Zodiac coined his name in a series of taunting messages that he mailed to regional newspapers, in which he threatened killing sprees and bombings if they were not printed. He also said that he was collecting his victims as slaves for the afterlife. He included four cryptograms or ciphers in his correspondence; two were decrypted in 1969 and 2020, and two are generally considered to be un ...

Tifinagh
Tifinagh ( Tuareg Berber language: ; Neo-Tifinagh: ; Berber Latin alphabet: ; ) is a script used to write the Berber languages. Tifinagh is descended from the ancient Libyco-Berber alphabet. The traditional Tifinagh, sometimes called Tuareg Tifinagh, is still favored by the Tuareg people of the Sahara desert in southern Algeria, northeastern Mali, northern Niger, and northern Burkina Faso for writing the Tuareg languages. Neo-Tifinagh is an alphabet developed by the Berber Academy by adopting Tuareg Tifinagh for use for Kabyle; it has been since modified for use across North Africa. Tifinagh is one of three major competing Berber orthographies alongside the Berber Latin alphabet and the Arabic alphabet. Tifinagh is the official script for Tamazight, an official language of Morocco and Algeria. Outside of symbolic cultural uses, Latin remains the dominant script for writing Berber languages throughout North Africa. The ancient Libyco-Berber script was used by the ancient north ...

Teth
Teth, also written as or Tet, is the ninth letter of the Semitic abjads, including Phoenician ''ṭēt'' 𐤈, Hebrew, Aramaic ''ṭēṯ'' 𐡈, and Syriac ''ṭēṯ'' ܛ, and Arabic ''ṭāʾ'' . It is also related to the Ancient North Arabian 𐪗, South Arabian , and Geʽez . The Phoenician letter also gave rise to the Greek theta (), originally an aspirated voiceless dental stop but now used for the voiceless dental fricative. The Arabic letter (ط) is sometimes transliterated as ''Tah'' in English, for example in Arabic script in Unicode. The sound value of Teth is , one of the Semitic emphatic consonants. Origins The Phoenician letter name may mean " spinning wheel" pictured as (compare Hebrew root (''ṭ-w-y'') meaning 'spinning' (a thread) which begins with Teth). According to another hypothesis (Brian Colless), the letter possibly continues a Middle Bronze Age glyph named 'good', Aramaic 'tav', Hebrew 'tov', Syriac ܛܒܐ 'tava', modern Arabi ...

Carian Alphabets
The Carian alphabets are a number of regional scripts used to write the Carian language of western Anatolia. They consisted of some 30 alphabetic letters, with several geographic variants in Caria and a homogeneous variant attested from the Nile delta, where Carians, Carian mercenary, mercenaries fought for the Egyptian pharaohs. They were written left-to-right in Caria (apart from the Carian–Lydian city of Tralleis) and right-to-left in Egypt. Carian was deciphered primarily through Egyptian–Carian bilingual tomb inscriptions, starting with John Ray in 1981; previously only a few sound values and the alphabetic nature of the script had been demonstrated. The readings of Ray and subsequent scholars were largely confirmed with a Carian–Greek bilingual inscription discovered in Kaunos in 1996, which for the first time verified personal names, but the identification of many letters remains provisional and debated, and a few letters are wholly unknown. The Carian alphabet resem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
