History of computers1
The first computers were human beings whose job was to perform complex calculations manually. This led to the development of early mechanical calculating devices like the abacus to aid these "human computers". Over centuries, inventors searched for ways to mechanize calculation, resulting in innovations like Napier's Bones, the slide rule, and early mechanical calculators invented by Wilhelm Schickard, Blaise Pascal, and others. However, the first modern computers were electronic devices that could perform calculations automatically.
History of computer
Thousands of years ago, people used bones and stones to keep accounts and perform calculations. As the need for more complex calculations grew, early calculating devices were developed, beginning with the abacus. Over many years, inventors created numerous mechanical calculating machines using new technologies and principles, including the Napier bones, slide rule, Pascaline, stepped reckoner, and Leibniz calculator. These inventions paved the way for modern computers by demonstrating how numbers could be mechanically manipulated through gears, wheels and other analog components.
History of computer
The abacus was an early calculating tool used by ancient Babylonians. In the 1600s, important early calculating devices were invented including logarithms by John Napier, which allowed multiplication via addition, and Pascal's mechanical calculator. In the 1820s, Charles Babbage proposed plans for an automatic mechanical calculator called the Difference Engine. Herman Hollerith later invented a punched card reader and mechanical counter that automated census data tabulation, laying the foundations for modern computing.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Computer history of 4 q seungri
- 2. .The Abacas. The abacas was the first calculating machine. It was developed by the Chinese about 5000years ago. It was built out of wood and beads. It could be held and carried around easily . Abacus was so successful that ita use spread from China to many other countries. The abacus is still in use in some countries today.
- 3. In 1617, John Napier, a mathematician from Scotland, invented calculating rods called Napier’s Bones. The rods were used to help people multiply large numbers. By moving the rods around and reading rows of numbers. .Napier’s Bones.
- 4. Some years later, in 1642, a young French Mathematician named Blasé Pascal was working in his father’s office. His job was to add long columns of tax figures. Doing all this adding was boring and time-consuming. So, Pascal came up with a way to get a job done faster. He invented a machine, the size of a shoe box, that could add and subtract numbers. .Pascal’s Arithmetic Machine.
