Caleb (^{[pronunciation?]}; כָּלֵב, Kalev; Tiberian vocalization: Kālēḇ; Hebrew Academy: Kalev) is a male given name. A character called Caleb is named in the Bible. A reference to him may also be found in the Quran, although his name is not mentioned.

When the Hebrews came to the outskirts of Canaan, the land that had been promised to them by God, after having fled slavery in Egypt, Moses (the Hebrew leader) sent twelve spies (Hebrew: מרגלים‎, meraglim) into Canaan to report on what was there—one spy representing each of the Twelve Tribes. Ten of the spies returned to say that the land would be impossible to claim, and that giants lived there who would crush the Hebrew army. Only two, Joshua (from the tribe of Ephraim) and Caleb (representing Judah), returned and said that God would be able to deliver Canaan into the hands of the Hebrew nation.

The Bible records that, because of the testimony of ten of the spies, the Hebrews chose not to enter Canaan. For this disobedience, God caused them to wander in the desert for forty years before being allowed to enter Canaan and conquer it as their home. The only adult Israelites allowed to survive these forty years and enter Canaan were Joshua and Caleb (son of Jephunneh), as a reward for their faith in God. This is recorded in the Book of Numbers. Caleb is called "my servant" by God in Numbers 14:24, a position of the highest honor heretofore used only for Moses. Caleb, son of Jephunneh,first mentioned in the above account (Numbers 13:6) is not to be confused with another Caleb, great-grandson of Judah through Tamar( 1 Chronicles 2:3-9). This other Caleb was the son of Hezron, and his wife was Azubah (I Chronicles 2:18,19).

Mao Zedong, also transliterated as Mao Tse-tung  listen (help·info), and commonly referred to as Chairman Mao (December 26, 1893 – September 9, 1976), was a Chinese Communist revolutionary, guerrilla warfare strategist, Marxist political philosopher, and leader of the Chinese Revolution. He was the architect and founding father of the People's Republic of China (PRC) from its establishment in 1949, and held authoritarian control over the nation until his death in 1976. His theoretical contribution to Marxism–Leninism, along with his military strategies and brand of policies, are collectively known as Maoism.

Mao rose to power by commanding the Long March, forming a Second United Front with Kuomintang (KMT) during the Second Sino-Japanese War to repel a Japanese invasion, and leading the Communist Party of China (CPC) to victory against Generalissimo Chiang Kai-shek's Kuomintang (KMT) in the Chinese Civil War. After solidifying the reunification of China through his Campaign to Suppress Counterrevolutionaries, Mao enacted sweeping land reform, by using violence and terror to overthrow the feudal landlords before seizing their large estates and dividing the land into people's communes. During the years when Mao was China’s 'Great Helmsman', a range of positive changes came to China. These included promoting the status of women, improving popular literacy, doubling the school population, providing universal housing, abolishing unemployment and inflation, increasing health care access, and dramatically raising life expectancy. In addition, China's population almost doubled during the period of Mao's leadership (from around 550 to over 900 million). As a result, Mao is still officially held in high regard by many in China as a great political strategist, military mastermind, and savior of the nation. Maoists further promote his role as a theorist, statesman, poet, and visionary, while anti-revisionists continue to defend most of his policies.

Aaron Swartz (born November 8, 1986) is an American programmer, writer, political organizer and Internet activist. He is best known in programming circles for co-authoring the RSS 1.0 specification. He received mainstream media attention after his federal indictment and arrest on 19 July 2011, for allegedly harvesting academic journal articles from JSTOR.

Swartz is the co-founder of Demand Progress and the Progressive Change Campaign Committee. He currently lives in Brooklyn, New York.

Swartz was active in discussions of Internet standards from an early age, and co-authored the specification for RSS by the time he was 14.^{[citation needed]} Since then he has been a member of the W3C's RDF Core Working Group, co-designed the formatting language Markdown with John Gruber, and worked on many other projects.

Swartz attended Stanford University for a year, leaving to start the software company Infogami, a startup that was funded by Y Combinator's first Summer Founders Program. Infogami was built around a wiki backend, a subject of interest for Swartz since his early effort to develop theinfo, a wiki-based encyclopedia, in 2000.
