I would like to briefly address the question of whether neural networks can achieve anything significant in art and literature, and whether this constitutes creativity without delving into technical details. Technical information is easily found, with well-known applications as examples. Here, I aim to explore the essence of the phenomenon; everything written here is far from […]

The stages of data retrieval, processing, and recording take time. A little, but for a large system, this can lead to significant delays. The storage issue is a matter of access to the data. They […]
This article will reveal some non-obvious aspects related to the use of wildcards when copying, the ambiguous behavior of the cp command during copy operations, as well as methods to correctly copy a large number of files without misses and crashes. Suppose we need to copy everything from the /source folder to the /target folder. The first thing that comes to mind is: cp /source/* /target Let's fix […]
