Laomedon

In Greek mythology, Laomedon was a Trojan king, son of Ilus and thus nephew of Ganymede and Assaracus. Laomedon was the father of Priam, Lampus, Clytius, Proclia, Medesicaste and Hesione. Tithonus is described by most sources as Laomedon's eldest legitimate son. Laomedon's possible wives are Placia and Leucippe, he had a son named Bucolion by the nymph Calybe, as recounted by Homer in the Iliad. Dictys Cretensis added Thymoetes to the list of Laomedon's children. Laomedon owned several horses with divine parentage that Zeus had given Tros as compensation for the kidnapping of Ganymede. Anchises secretly bred his own mares from these horses. According to one story, Laomedon's son, was kidnapped by Zeus, who had fallen in love with the beautiful boy. Laomedon grieved for his son. Sympathetic, Zeus sent Hermes with two horses so swift. Hermes assured Laomedon that Ganymede was immortal and would be the cupbearer for the gods, a position of much distinction. However, Ganymede is more described as a son of Tros, an earlier King of Troy and grandfather of Laomedon.

Laomedon himself was the son of Ganymede's brother Ilus, the son of Tros. When Poseidon and Apollo entered a conspiracy to put Zeus in bonds, the supreme god being offended, sent them to serve with King Laomedon as punishment for their nefarious design. In other sources, the two gods tested the wantonness of the Laomedon; as ordered by Laomedon who promised wages, the two deities assuming the likeness of men undertook to build huge walls around the city. But when they had finished, the king refused to fulfil their agreement of reward. In vengeance, before the Trojan War, Apollo sent a pestilence to Troy while Poseidon released a sea monster which, carried up by a flood, snatched away the people of the plain; the oracles foretold deliverance from these calamities if Laomedon would expose his daughter Hesione to be devoured by the sea monster. The king exposed her by fastening her to the rocks near the sea, but by chance, after fighting the Amazons, who had landed at Troy, saw the girl to be sacrificed.

The hero promised to save the princess on condition of receiving from Laomedon the mares which Zeus had given in compensation for the rape of Ganymede. When Laomedon agreed, Heracles rescued Hesione at the last minute, but when Laomedon would not give up his magical horses for their deeds, the hero put to sea after threatening to make war on Troy. After his servitude, Heracles mustered an army of noble volunteers and sailed for Ilium with eighteen ships of fifty oars each. Having come to port at Ilium, he left the guard of the ships to Oicles and he, with the rest of the champions, set out to attack the city. Meanwhile, Laomedon marched against the ships with a slew Oicles in battle, but being repulsed by the troops of Heracles, Laomedon was besieged. The siege once laid, Telamon was the first to breach the wall and enter the city, after him Heracles; when the son of Zeus had taken the city he shot down his sons, except Podarces. Heracles assigned Hesione as a war prize to Telamon and allowed her to take with her whomsoever of the captives she would.

When Hesione chose Podarces, Heracles said that her brother must first be a slave and be ransomed by her. So, when the prince was being sold, Hesione took the golden veil from her head and gave it as a ransom.

Liujiang District

Liujiang District is under the administration of Liuzhou, Guangxi Zhuang Autonomous Region, located on the southwest bank of the Liu River. It covers a land area of 2,504 square kilometres and had a population of 562,351 as of 2010; the southernmost county-level division of Liuzhou City, it lies south of Liuzhou's city proper, bordering the prefecture-level cities of Laibin to the south and Hechi to the northwest. Liucheng consists of 11 towns and 1 township:Towns: Labao, Baipeng, Luoman, Sandu, Jiangde, Shibo The only township in the Baisha Township Guizhou–Guangxi Railway These findings might give some support to the claim that modern humans from Africa arrived at southern China about 100,000 years BP

BESK

BESK was Sweden's first electronic computer, using vacuum tubes instead of relays. It was developed by Matematikmaskinnämnden and for a short time it was the fastest computer in the world; the computer was completed in 1953 and in use until 1966. The technology behind BESK was continued with the transistorized FACIT EDB and FACIT EDB-3 machines, both software compatible with BESK. Non-compatible machines inspired by BESK were SMIL made for the University of Lund, SAABs räkneautomat SARA, "SAAB's calculating machine", DASK made in Denmark. BESK was developed by the Swedish Board for Computing Machinery a few years after the mechanical relay computer BARK; the team was led by Conny Palm, who died in December 1951, after which Stig Comét took over. The hardware was developed by Erik Stemme. Gösta Neovius and Olle Karlqvist were responsible for instruction set, it was modeled on the IAS machine for which the design team had retrieved drawings during a scholarship to Institute for Advanced Study and Massachusetts Institute of Technology, U.

S. During the development of the BESK magnetic drum memory, Olle Karlqvist discovered a magnetic phenomenon, called the Karlqvist gap. BESK was a 40-bit machine; the electrostatic memory could store 512 words. The instruction length was 20 bits, so each word could store two instructions. BESK contained 400 germanium diodes; the power consumption was 15 kVA. An average runtime of 5 minutes was achieved before hardware problems appeared. In 1954 the system became more stable. Breakpoints were introduced to allow software restart after hardware failures. BESK had a British Williams tube 512 word x 40 bit memory based on 40 cathode tubes, eight spare tubes; the memory was from the beginning found to be insufficient and Carl-Ivar Bergman was given just a few weeks to build and install a ferrite core memory in 1956. To get finished before the deadline they hired housewives with knitting experience to make the memory. One of the new memory bits did not work at first, but it was cut out and replaced. BESK was inaugurated on April 1, 1954 and handled weather data for Carl-Gustaf Rossby and the Swedish Meteorological and Hydrological Institute, statistics for the telecommunications service provider Televerket, wing profiles for the attack aircraft Saab Lansen, road profiles for the road authority Vägverket.

During the nights Swedish National Defence Radio Establishment used BESK for cracking encryption of radio messages. BESK was used for calculations for the Swedish nuclear energy industry, for example Monte Carlo simulations of neutron spectrum, for the Swedish nuclear weapon program, but most of those calculations were done by SMIL. In 1957 Hans Riesel used BESK to discover a Mersenne prime with 969 digits - the largest prime known at the time. SAAB rented computer time on the BESK to make calculations of the strength of the Saab Lansen attack aircraft. In the fall of 1955 SAAB thought the capacity was insufficient and started working on SAABs räkneautomat SARA, "SAAB's calculating machine", going to be twice as fast as BESK; some former SARA employees went to Facit and worked with the FACIT EDB. In the spring of 1956, eighteen of the BESK developers were hired by office equipment manufacturer Facit and housed in an office at Karlavägen 62 in Stockholm, where they started to build copies of BESK called Facit EDB, led by Carl-Ivar Bergman.

A total of nine machines were built, of which four were used internally by Facit Electronics and five were sold to customers. On July 1, 1960, Facit Electronics with 135 employees moved to Solna, just north of Stockholm. In 1960 BESK was used to create an animation of a car driving down a planned highway from the driver's perspective; this was one of the earliest computer animations made. The short clip was broadcast on Swedish national television on 9 November 1961. "Besk" is Swedish for the taste "bitter". Bäsk is the name of a traditional bitters made from distilled alcohol seasoned with the herb Artemisia absinthium L. local to the province of Skåne, in which Lund is located. This was an intentional and unnoticed pun after officials denied usage of the name CONIAC for the predecessor BARK. BARK - Binär Aritmetisk Relä-Kalkylator - Sweden's first computer.
