Programming of the ELWAT analog computer since the late 1960s. By connecting the connection card
Mechanical counting devices have been created since ancient times. The Antikithira mechanism from ancient Greece (150-100 BC) was a mechanical calculator based on a set of gears used for astronomical calculations. In 1206, the Arab inventor Al-Jazari built a programmable drum machine with chopsticks and cams mounted on a wooden drum in certain places. As the drum rotated, they hit levers that played a specific sound on the percussion instrument. In 1805, the Joseph Marie Jacquard loom was created. The machine used pre-punched cards on which the fabric pattern was recorded. By changing the set of cards, you can get fabrics with different patterns. This idea was later picked up by Herman Hollerith from IBM.
In 1833, Charles Babbage began building an analytical engine, which was essentially a mechanical, programmable computer that was ahead of its time. Due to construction difficulties and lack of interest from the British government, the inventor did not finish his invention, but the project was described by Ada Lovelace, who also wrote the first program for him that calculates Bernoulli numbers, and thus became the first programmer (actually programmer) in history.
The invention of the von Neumann architecture made it possible to store computer programs in computer RAM along with data. The first programs had to be represented directly from the operations offered by a particular machine, often in binary notation. Each model used its own set of commands, which limited portability. In later years, the first assemblers were developed, where the programmer could enter instructions in text format using a symbolic entry instead of an order number, for example, ADD X, TOTAL. In 1954, the first high-level programming language, FORTRAN, was created, where programmers could directly formulate mathematical expressions in the same style that we are used to: y= x^2 + 5*x - 7. The text of the program or its source was translated into a machine-readable form using a special application called a compiler. In the following years, new programming languages were created, often focused on creating applications of a certain type.
In the early years of the computer (around 1940-1960), computer programs were entered into computer memory using punched cards or paper tapes. In the late 60s, the first devices for electronic information storage and computer terminals appeared, thanks to which the source code could be entered directly into a computer using word processors.
Along with the development of the Internet and computer networks, tools have emerged to facilitate collaboration on software, such as version control systems. The source code is stored here on a central server, and developers send patches from their local copies to it. All changes are recorded, and the management program can intelligently combine fragments modified independently by two programmers, so there can be no situation of accidentally deleting the work of another team member.
Computer programming is currently an attractive career in almost all developed countries due to the ever-increasing demand for new computer applications. Some of the richest people in the world are programmers by profession, such as Bill Gates (Microsoft), Larry Ellison (Oracle), Larry Page (Google) and Hasso Plattner (SAP).
