Where did the word bug come from in the meaning of malfunction?

On September 9, 1947, engineers at Harvard University discovered the cause of a malfunction of the Mark II computer - a moth stuck between the relay contacts. One of them documented an incident called "The first case of finding a bug" (in English, "bug" means "insect"). However, the word "bug" for technical malfunctions began to be used long before that, for example, it is found in Edison's diary. The word "debugging" in the sense of "debugging, correcting errors" also appeared earlier - the Oxford Dictionary of 1945 described it in relation to the repair of aircraft engines.

Random interesting fact from the Great Encyclopedia:

When did surnames appear?

"Hey, shorty!"

"Hey, skinny."

"Here comes the Blonde!"

Is this familiar to you? We consider it quite normal to give people nicknames that characterize them to a certain extent.

It is interesting that the names appeared in exactly the same way! A girl born during a famine could be called Una (translated from the Celtic "hunger"), a fair-haired girl would be called Blanche (French for "white"). The boy would be named David, which means "beloved."

People have had names for many thousands of years. Then, around 1066, when the Normans took over England, they began to use surnames to better distinguish between people. Just a name is not enough to distinguish one person from another. For example, there could be two Davids in the city, one of them was lazy. So people would call him David Slugger.

There are various ways to come up with middle names for people. For example, they began to mention the name of the father. So, Peter, the son of Andrei, became known as Peter Andreev's son, and later - Peter Andreevich.

Another way to distinguish people was to mention the area where they were born or lived. The man who lived or worked at the mill became known as Melnikov, who lived near the grove - Roshchin.

And, of course, the work performed by a person made it possible to distinguish him from others. So the Kozhemyakins, Tokarevs, Plotnikovs and others appeared.

Something similar existed in ancient Rome. The second name - patronymic - was added to mention the name of the family or clan to which the child belonged. Later they began to add a third name, a kind of descriptive nickname.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>
