Mbé vs Bytom

Informations

In computer science, group coded recording or group code recording (GCR) refers to several distinct but related encoding methods for representing data on magnetic media. The first, used in 6250 bpi magnetic tape since 1973, is an error-correcting code combined with a run-length limited (RLL) encoding scheme, belonging into the group of modulation codes.

The others are different mainframe hard disk as well as floppy disk encoding methods used in some microcomputers until the late 1980s. GCR is a modified form of a NRZI code, but necessarily with a higher transition density.

Bytom (Polish pronunciation: [ˈbɨtɔm] (listen); Silesian: Bytōm, Bytōń, German: Beuthen O.S.) is a city with powiat rights in southern Poland, in Silesia, in centre of Metropolitan Association of Upper Silesia and Dąbrowa Basin. It is one of the oldest cities in the Upper Silesia, and the former seat of the Piast dukes of the Duchy of Bytom. Until 1532, it was in the hands of the Silesian Piasts, then it belonged to the Hohenzollern dynasty. After 1623 it was a state country in the hands of the Donnersmarck family. From 1742 to 1945 the town was within the borders of Prussia and Germany, and played an important role as an economic and administrative centre of the local industrial region. Until the outbreak of World War II, it was the main centre of national, social, cultural and publishing organisations fighting to preserve Polish identity in Upper Silesia.

During Kristallnacht in 1938, Nazi Germans burned down the Bytom Synagogue. In 1942, the Beuthen Jewish community was liquidated and its members were the first transport to be sent to Auschwitz concentration camp. After the war, decades of the Polish People's Republic were characterized by a constant emphasis on the development of heavy industry, which deeply polluted and degraded Bytom. After 1989, the city experienced a socio-economic decline. The city is blighted with derelict, dilapidated buildings which are ubiquitous. The population has been in rapid decline since 1999 leading to a number of locals describing the city as a ghost town. Poverty remains rife in Bytom. However, it is an important place in the cultural, entertainment, and industrial map of the region.
