Pakistan (ⁱ/ˈpækᵻstæn/ or ⁱ/pɑːkiˈstɑːn/; Urdu: پاكستان‎ ALA-LC: Pākistān, pronounced [pɑːkɪst̪ɑːn]), officially the Islamic Republic of Pakistan (Urdu: اسلامی جمہوریۂ پاكستان‎ ALA-LC: Islāmī Jumhūriyah Pākistān IPA: [ɪslɑːmiː d͡ʒʊmɦuːriəɪh pɑːkɪst̪ɑːn]), is a country in South Asia. It is the sixth-most populous country with a population exceeding 199 million people. It is the 36th largest country in the world in terms of area with an area covering 881,913 km² (340,509 sq mi). Pakistan has a 1,046-kilometre (650 mi) coastline along the Arabian Sea and the Gulf of Oman in the south and is bordered by India to the east, Afghanistan to the west, Iran to the southwest and China in the far northeast respectively. It is separated from Tajikistan by Afghanistan's narrow Wakhan Corridor in the north, and also shares a maritime border with Oman.

The territory that now constitutes Pakistan was previously home to several ancient cultures, including the Mehrgarh of the Neolithic and the Bronze Age Indus Valley Civilisation, and was later home to kingdoms ruled by people of different faiths and cultures, including Hindus, Indo-Greeks, Muslims, Turco-Mongols, Afghans and Sikhs. The area has been ruled by numerous empires and dynasties, including the Indian Mauryan Empire, the Persian Achaemenid Empire, Alexander of Macedonia, the Arab Umayyad Caliphate, the Mongol Empire, the Mughal Empire, the Durrani Empire, the Sikh Empire and the British Empire. As a result of the Pakistan Movement led by Muhammad Ali Jinnah and the subcontinent's struggle for independence, Pakistan was created in 1947 as an independent nation for Muslims from the regions in the east and west of the Subcontinent where there was a Muslim majority. Initially a dominion, Pakistan adopted a new constitution in 1956, becoming an Islamic republic. A civil war in 1971 resulted in the secession of East Pakistan as the new country of Bangladesh.

Pakistanis

Pakistanis (Urdu: پاكِستانى قوم‎; Pakistani Qaum) are the people who are citizens of the modern State of Pakistan and their descendants. Pakistan is a multi-ethnic and multilingual state: the majority of its people belong linguistically to the Indo-Aryan group, and there are significant minorities belonging to the Iranic and Dard subgroups among others. As of 2011, the estimated population of Pakistan was over 199 million making it the world's sixth most-populous country.

Ethnic sub-groups

Pakistan has one of the world's fastest growing populations. As the country is located in South Asia, Pakistani people are a mixture of various ethnic groups. Several ethnic groups, invading armies and the migrations to the region by people passing through on their way to and from Indus have left their imprint on the population.

Pakistani people belong predominantly to seven main ethno-linguistic groups: Punjabis, Sindhis, Seraikis, Pashtuns, Mohajirs, Balochs, and Kashmiris, with substantial numbers of Brahuis, Hindkowans, Shins, Burushos, Wakhis, Baltis, Chitralis and other small, minority ethnic groups in the remote north of the country.

White hat (computer security)

The term "white hat" in Internet slang refers to an ethical computer hacker, or a computer security expert, who specializes in penetration testing and in other testing methodologies to ensure the security of an organization's information systems.Ethical hacking is a term coined by IBM meant to imply a broader category than just penetration testing. White-hat hackers may also work in teams called "sneakers",red teams, or tiger teams.

History

One of the first instances of an ethical hack being used was a "security evaluation" conducted by the United States Air Force of the Multics operating systems for "potential use as a two-level (secret/top secret) system." Their evaluation found that while Multics was "significantly better than other conventional systems," it also had "... vulnerabilities in hardware security, software security and procedural security" that could be uncovered with "a relatively low level of effort." The authors performed their tests under a guideline of realism, so that their results would accurately represent the kinds of access that an intruder could potentially achieve. They performed tests that were simple information-gathering exercises, as well as other tests that were outright attacks upon the system that might damage its integrity. Clearly, their audience wanted to know both results. There are several other now unclassified reports that describe ethical hacking activities within the U.S. military.

Eight-ball

Eight-ball (often spelled 8-ball or eightball, and sometimes called solids and stripes, spots and stripes in the UK or, more rarely, bigs and littles/smalls or highs and lows) is a pool (pocket billiards) game popular in much of the world, and the subject of international professional and amateur competition. Played on a pool table with six pockets, the game is so universally known in some countries that beginners are often unaware of other pool games and believe the word "pool" itself refers to eight-ball. The game has numerous variations, including Alabama eight-ball, crazy eight, last pocket, misery, Missouri, 1 and 15 in the sides, rotation eight ball, soft eight, and others. Standard eight-ball is the second most competitive professional pool game, after nine-ball and for the last several decades ahead of straight pool.

Eight-ball is played with cue sticks and 16 balls: a cue ball, and 15 object balls consisting of seven striped balls, seven solid-colored balls and the black 8 ball. After the balls are scattered with a break shot, the players are assigned either the group of solid balls or the stripes once a ball from a particular group is legally pocketed. The ultimate object of the game is to legally pocket the eight ball in a called pocket, which can only be done after all of the balls from a player's assigned group have been cleared from the table.
