Rule Of Three (C Programming)
The rule of three and rule of five are rules of thumb in C++ for the building of exception-safe code and for formalizing rules on resource management. The rules prescribe how the default members of a class should be used to achieve these goals systematically. Rule of three The rule of three (also known as ''the law of the big three'' or ''the big three'') is a rule of thumb in C++ (prior to C++11) that claims that if a class defines any of the following then it should probably explicitly define all three: * destructor * copy constructor * copy assignment operator These three functions are special member functions. If one of these functions is used without first being declared by the programmer it will be implicitly implemented by the compiler with the following default semantics: * Destructor – call the destructors of all the object's class-type members * Copy constructor – construct all the object's members from the corresponding members of the copy constructor's a ...

Rule Of Three (aeronautics)
In aviation, the rule of three or "3:1 rule of descent" is a rule of thumb that of travel should be allowed for every of descent. For example, a descent from flight level In aviation and aviation meteorology, a flight level (FL) is an aircraft's altitude at standard air pressure, expressed in hundreds of feet. The air pressure is computed assuming an International Standard Atmosphere pressure of 1013.25 hPa ... 350 would require approximately 35x3=105 nautical miles. This would have to be adjusted for headwind or tailwind. Alternatively, David P. Davies gives the rule as 300 feet of descent required for each nautical mile of distance. Large aircraft approaching to land normally use a 3 degree approach path. This is equivalent to 3.14 nautical miles per 1000 ft of descent. If exactly 3 nmi are allowed per 1000 ft of descent, the glide path will be 3.14 degrees. See also * ICAO recommendations on use of the International System of Units References ...

Rule Of Thirds (military)
The rule of thirds is a rule of thumb used when planning for the deployment and usage of a military organization , according to which one third of the total military forces involved should be available for operations, one third should be preparing for operations, and the final third, having been on operations, should be recuperating. Ideally, units and individuals regularly will rotate through each of the three phases. Variations and implications Different nations and militaries will vary the rule of thirds according to their own financial and manpower situations. At times of financial constraint, rather than increasing the total number of forces, one temptation of politicians is to attempt to increase available manpower by folding together the preparation and recuperation phases, creating a ''rule of halves''. A rule of halves was actually the basis of British Army planning during the British Empire, with each regiment consisting of a pair of battalions which would take turns ...

Rule Of Thirds (diving)
In scuba diving, the rule of thirds is a rule of thumb used by divers to plan dives so they have enough breathing gas remaining in their diving cylinder at the end of the dive to be able to complete the dive safely. This rule generally only applies to diving in overhead environments, such as caves and wrecks, where a direct ascent to the surface is impossible and the divers must return the way they came. For divers following the rule, one third of the gas supply is planned for the outward journey, one third is for the return journey and one third is a safety reserve. However, when diving with a buddy with a higher breathing rate or a different volume of gas, it may be necessary to set one third of the buddy's gas supply as the remaining 'third'. This means that the turn point to exit is earlier, or that the diver with the lower breathing rate carries a larger volume of gas than he alone requires. Reserves are needed at the end of dives in case the diver has gone deeper or longer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rule Of Thirds
The rule of thirds is a "rule of thumb" for composing visual arts, visual images such as designs, films, paintings, and photography, photographs. The guideline proposes that an image should be imagined as divided into nine equal parts by two equally spaced horizontal lines and two equally spaced vertical lines, and that important compositional elements should be placed along these lines or their intersections. Proponents of the technique claim that aligning a subject with these points creates more tension, energy and interest in the composition than simply centering the subject. The photograph on the right demonstrates the application of the rule of thirds. The horizon in the photograph sits at the horizontal line dividing the lower third of the photo from the upper two-thirds. The tree sits at the intersection of two lines, sometimes called a ''power point'' or a ''crash point''. Some proponents claim that points of interest in the photo do not have to actually touch one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rule Of Three (writing)
The rule of three is a writing principle that suggests that a trio of entities such as events or characters is more humorous, satisfying, or effective than other numbers. The audience of this form of text is also thereby more likely to remember the information conveyed because having three entities combines both brevity and rhythm with having the smallest amount of information to create a pattern. Slogans, film titles, and a variety of other things have been structured in threes, a tradition that grew out of oral storytelling. Examples include the Three Little Pigs, Three Billy Goats Gruff, Goldilocks and the Three Bears, and the Three Musketeers. Similarly, adjectives are often grouped in threes to emphasize an idea. Meaning The rule of three can refer to a collection of three words, phrases, sentences, lines, paragraphs/stanzas, chapters/sections of writing and even whole books. The three elements together are known as a triad. The technique is used not just in prose, but al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rule Of Three (Wicca)
The Rule of Three (also Three-fold Law or Law of Return) is a religious tenet held by some Wiccans, Neo-Pagans and occultists. It states that whatever energy a person puts out into the world, be it positive or negative, will be returned to that person three times. Some subscribe to a variant of this law in which return is not necessarily threefold. Rule of Three is sometimes described as karma by Wiccans; however, this is not strictly accurate. Both concepts describe the process of cause and effect and often encourage the individual to act in an upright way. In Hindu Vedanta literature, there is a comparable idea of threefold Karma referred to as Sanchita (accumulated works), Kriyamana, Agami, or Vartamana (current works), and Prarabdha (fructifying works), which are associated with past, present and future respectively. According to some traditions, the rule of three is not literal but symbolizes that our energy returns our way as many times as needed for us to learn the lesson ass ...

Rule Of Threes (survival)
In survival, the rule of threes involves the priorities in order to survive. The rule, depending on the place where one lives, may allow people to effectively prepare for emergencies and determine decision-making in case of injury or danger posed by the environment. Rule Normally, the rule of threes contains the following: * You can survive three ''minutes'' without breathable air (unconsciousness), or in icy water. * You can survive three ''hours'' in a harsh environment (extreme heat or cold). * You can survive three ''days'' without drinkable water. * You can survive three ''weeks'' without food. Each line assumes that the one(s) before it are met. For example, if you have a large quantity of food and water yet are exposed to the environment, then the harsh conditions rule applies. The rule may sometimes be useful in determining the order of priority when in a life-threatening situation, and is a generalization (or rule of thumb), not scientifically accurate. Additional ...

The Hunting Of The Snark
''The Hunting of the Snark'', subtitled ''An Agony in 8 Fits'', is a poem by the English writer Lewis Carroll. It is typically categorised as a nonsense poem. Written between 1874 and 1876, it borrows the setting, some creatures, and eight portmanteau words from Carroll's earlier poem "Jabberwocky" in his children's novel ''Through the Looking-Glass'' (1871). The narrative follows a crew of ten trying to hunt the Snark, a creature which may turn out to be a highly dangerous ''Boojum''. The only crewmember to find the Snark quietly vanishes, leading the narrator to explain that the Snark was a Boojum after all. The poem is dedicated to young Gertrude Chataway, whom Carroll met at the English seaside town Sandown in the Isle of Wight in 1875. Included with many copies of the first edition of the poem was Carroll's religious tract, ''An Easter Greeting to Every Child Who Loves "Alice"''. ''The Hunting of the Snark'' was published by Macmillan in the United Kingdom in March 1876 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agatha Christie Bibliography
Agatha Christie (1890–1976) was an English crime novelist, short-story writer and playwright. Her reputation rests on 66 detective novels and 15 short-story collections that have sold over two billion copies, an amount surpassed only by the Bible and the works of William Shakespeare. She is also the most translated individual author in the world with her books having been translated into more than 100 languages. Her works contain several regular characters with whom the public became familiar, including Hercule Poirot, Miss Marple, Tommy and Tuppence Beresford, Parker Pyne and Harley Quin. Christie wrote more Poirot stories than any of the others, even though she thought the character to be "rather insufferable". Following the publication of the 1975 novel ''Curtain'', Poirot's obituary appeared on the front page of ''The New York Times''. She married Archibald Christie in December 1914, but the couple divorced in 1928. After he was sent to the Western Front in the First W ...
