Leibniz was a strong advocate of the binary number system. Binary numbers are ideal for machines because they require only two digits, which can easily be represented by the on and off states of a switch. When computers became electronic, the binary system was particularly appropriate because an electrical circuit is either on or off. This meant that on could represent true, off could represent false, and the flow of current would directly represent the flow of logic. Leibniz was prescient in seeing the appropriateness of the binary system in calculating machines, but his machine did not use it.
The Coming Software Apocalypse
Instead, the Step Reckoner represented numbers in decimal form, as positions on position dials. Even decimal representation was not a given: in Samuel Morland invented an adding machine specialized for British money—a decidedly nondecimal system. With other activities being mechanized, why not calculation? In Charles Xavier Thomas de Colmar of France effectively met this challenge when he built his Arithmometer , the first commercial mass-produced calculating device. It could perform addition, subtraction, multiplication, and, with some more elaborate user involvement, division.
Calculators such as the Arithmometer remained a fascination after , and their potential for commercial use was well understood. Many other mechanical devices built during the 19th century also performed repetitive functions more or less automatically, but few had any application to computing. There was one major exception: the Jacquard loom , invented in —05 by a French weaver, Joseph-Marie Jacquard. The Jacquard loom was a marvel of the Industrial Revolution. A textile-weaving loom, it could also be called the first practical information-processing device.
The loom worked by tugging various-coloured threads into patterns by means of an array of rods. By inserting a card punched with holes, an operator could control the motion of the rods and thereby alter the pattern of the weave. Moreover, the loom was equipped with a card-reading device that slipped a new card from a prepunched deck into place every time the shuttle was thrown, so that complex weaving patterns could be automated.
What was extraordinary about the device was that it transferred the design process from a labour-intensive weaving stage to a card-punching stage. Once the cards had been punched and assembled, the design was complete, and the loom implemented the design automatically. The Jacquard loom, therefore, could be said to be programmed for different patterns by these decks of punched cards. For those intent on mechanizing calculations, the Jacquard loom provided important lessons: the sequence of operations that a machine performs could be controlled to make the machine do something quite different; a punched card could be used as a medium for directing the machine; and, most important, a device could be directed to perform different tasks by feeding it instructions in a sort of language—i.
It is not too great a stretch to say that, in the Jacquard loom, programming was invented before the computer.
The robots mimic the action of human to browse, search and extract the data. Advanced setting including web scrolling, wait before execution and etc makes the whole extraction process humanized and smoother. You can enjoy a sip of coffee and leave the extraction to Octoparse by setting the extraction time and frequency. Data cleaning at ease with Octoparse built-in RegEx Tool. Previous post. So I sought data on who is.
