RST code
The RST system is used by amateur radio operators, shortwave listeners, and other radio hobbyists to exchange information about the quality of a radio signal being received. The code is a three digit number, with one digit each for conveying an assessment of the signal's readability, strength, and tone. The code was developed in the 1934 by Amateur radio operator Arthur W. Braaten, W2BSR.
Readability
The R stands for "Readability". Readability is a qualitative assessment of how easy or difficult it is to correctly copy the information being sent during the transmission. In a Morse code telegraphy transmission, readability refers to how easy or difficult it is to distinguish each of the characters in the text of the message being sent; in a voice transmission, readability refers to how easy or difficult it is for each spoken word to be understood correctly. Readability is measured on a scale of 1 to 5.

Ole Martin Årst
Ole Martin Årst (born 19 July 1974) is a Norwegian retired footballer. He is a former top scorer in both Belgium's and Norway's top leagues.
Club career
Årst was born in Bergen, but grew up in Tromsø. He made his professional debut for Tromsø IL on 22 April 1995 against Hamarkameratene at Briskeby stadion. After the 1997 season he was sold to Anderlecht for NOK 13 million. He then moved to K.A.A. Gent in Belgium and ended up as a top goalscorer in 2000 with 30 goals. Then Standard Liège signed him for NOK 24 million. He returned to Tromsø IL in the summer of 2003 for NOK 5 million.
Årst became the top scorer in the Tippeligaen 2005, with 16 goals. After a hat-trick against IK Start on 2 October 2005 Årst was ranked as the top league scorer of all times in Tromsø IL with 51 goals. On 9 July 2007 he transferred to IK Start.
Start went down that season, but as Start won a direct promotion in 2008, Årst did not participate in any games due to a serious injury. The same injury limited him to only two games in the 2009 season.
Hamming space
In statistics and coding theory, a Hamming space is usually the set of all 
binary strings of length N. It is used in the theory of coding signals and transmission.
More generally, a Hamming space can be defined over any alphabet (set) Q as the set of words of a fixed length N with letters from Q. If Q is a finite field, then a Hamming space over Q is an N-dimensional vector space over Q. In the typical, binary case, the field is thus GF(2) (also denoted by Z2).
In coding theory, if Q has q elements, then any subset C (usually assumed of cardinality at least two) of the N-dimensional Hamming space over Q is called a q-ary code of length N; the elements of C are called codewords. In the case where C is a linear subspace of its Hamming space, it is called a linear code. A typical example of linear code is the Hamming code. Codes defined via a Hamming space necessarily have the same length for every codeword, so they are called block codes when it is necessary to distinguish them from variable-length codes that are defined by unique factorization on a monoid.
Code (album)
Code (stylized as C O D E) is an album by British electronic band Cabaret Voltaire. The track "Don't Argue" was released as a single, as was "Here To Go".
The lyrics (and title) of "Don't Argue" incorporate verbatim a number of sentences from the narration of the 1945 short film Your Job in Germany, directed by Frank Capra. The film was aimed at American soldiers occupying Germany and strongly warned against trusting or fraternizing with German citizens.

Code (law)
A code is a type of legislation that purports to exhaustively cover a complete system of laws or a particular area of law as it existed at the time the code was enacted, by a process of codification. Though the process and motivations for codification are similar in different common law and civil law systems, their usage is different. In a civil law country, a Code typically exhaustively covers the complete system of law, such as civil law or criminal law. By contrast, in a common law country with legislative practices in the English tradition, a Code is a less common form of legislation, which differs from usual legislation that, when enacted, modify the existing common law only to the extent of its express or implicit provision, but otherwise leaves the common law intact. By contrast, a code entirely replaces the common law in a particular area, leaving the common law inoperative unless and until the code is repealed. In a third case of slightly different usage, in the United States and other common law countries that have adopted similar legislative practices, a Code is a standing body of statute law on a particular area, which is added to, subtracted from, or otherwise modified by individual legislative enactments.
