Q: In signal processing, data compression, source coding, or bit-rate reduction involves encoding information using fewer bits than the original representation. Compression can be either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by identifying unnecessary information and removing it. The process of reducing the size of a data file is referred to as data compression. In the context of data transmission, it is called source coding (encoding done at the source of the data before it is stored or transmitted) in opposition to channel coding.

Compression is useful because it helps reduce resource usage, such as data storage space or transmission capacity. Because compressed data must be decompressed to use, this extra processing imposes computational or other costs through decompression; this situation is far from being a free lunch. Data compression is subject to a spacetime complexity trade-off. For instance, a compression scheme for video may require expensive hardware for the video to be decompressed fast enough to be viewed as it is being decompressed, and the option to decompress the video in full before watching it may be inconvenient or require additional storage. The design of data compression schemes involves trade-offs among various factors, including the degree of compression, the amount of distortion introduced (when using lossy data compression), and the computational resources required to compress and decompress the data.

Q: (CNN) -- The goals just keep flowing for Lionel Messi, who on Sunday surpassed soccer legend Pele's mark of 75 in a calendar year to help Barcelona bounce back from a rare defeat.

The Argentina star netted twice in the 4-2 win at Mallorca that kept the Catalans three points clear in Spain's La Liga, leaving him just nine short of Gerd Muller's all-time record.

The 25-year-old, who became a first-time father earlier this month, was able to put a bit more enthusiasm into his new thumb-sucking celebration than when he scored late in the shock midweek Champions League loss to Scottish side Celtic.

"Leo continually breaks records. His goal tally is spectacular," said Barca manager Tito Vilanova, who has yet to experience a domestic league defeat after his first 11 matches in charge, equaling the best start to a season set by Real Madrid.

"It takes other great players seven or eight seasons to score the amount of goals he scores in one season. Also, some of his goals are absolute beauties."

Messi has now scored 64 goals for his club and 12 for his country this year, from just 59 matches overall.

Pele managed 75 from 53 as a 17-year-old in 1958, helping Brazil to win the World Cup for the first of a record five times.

Muller, a World Cup winner in 1974, surpassed Pele's record in a year that West Germany won the European Championship.

Messi has yet to win a senior title with Argentina, though he won Olympic gold with the under-23 side in 2008.

Q: A shire is a traditional term for a division of land, found in the United Kingdom and some other English speaking countries. It was first used in Wessex from the beginning of Anglo-Saxon settlement, and spread to most of the rest of England in the tenth century. In some rural parts of Australia, a shire is a local government area; however, in Australia it is not synonymous with a "county", which is a lands administrative division.

The word derives from the Old English "scir", itself a derivative of the Proto-Germanic "skizo" (cf. Old High German "scira"), meaning care or official charge. In the UK, "shire" is the original term for what is usually known now as a "county"; the word "county" having been introduced at the Norman Conquest of England. The two are nearly synonymous. Although in modern British usage counties are referred to as "shires" mainly in poetic contexts, terms such as Shire Hall remain common. Shire also remains a common part of many county names.

In regions with so-called rhotic pronunciation such as Scotland, the word "shire" is pronounced or . In non-rhotic areas the final R is silent unless the next word begins in a vowel. When "shire" is a suffix as part of a placename in England, the vowel is unstressed and thus usually shortened and/or monophthongised: pronunciations include , or sometimes , with the pronunciation of the final R again depending on rhoticity. In many words, the vowel is normally reduced all the way to a single schwa, as in for instance "Leicestershire" or "Berkshire" . Outside England, and especially in Scotland and the US, it is more common for "shire" as part of a placename to be pronounced identically to the full word, as a result of spelling pronunciation.
