How do punched cards affect the operation of modern mail programs?

Punched cards, which were used as input and output media on the earliest computers, were designed to be 80 columns wide. To make it easier to transfer programs, the first displays were also designed for a line width of 80 characters. When e-mail appeared, the first protocols for it again operated with 80-character strings. Although monitors have evolved a lot since then, almost all popular mail systems still break lines at 80 characters to ensure compatibility with older programs. Even binary files are converted using MIME base64 to strings of letters and numbers with a maximum length of 80 characters. We can say that the programs change the video files we send to be compatible with punched cards.

Random interesting fact from the Great Encyclopedia:

Why are there so many rounded letters in the Burmese script?

In the Burmese language, almost all the lines of the letters are rounded. This is due to the fact that in Burma they traditionally wrote on palm leaves. They are convenient in size and available in large quantities, but are not too strong, so a writing stick can easily tear the sheet in a straight line.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Burglar alarm for laptop 21.05.2005

The Korean corporation "David & Chris" has patented an "anti-theft device" for portable computers.

If you are afraid that the laptop might be stolen while you leave it on the table in the library, for example, go to the bookshelves, you can turn on the alarm - and if you try to take the computer away, the motion sensor based on the accelerometer will turn on the siren. Only the owner can turn it off by entering a password known to him from the keyboard.
