This blog created at 2018.06.19, as a kind of private event store. Includes important personal logging entries. It may only contain content that is personal or relevant to my interests, such as electronic, IT, or other posts to be written. And I've decided to translate to English with help of Google Translate and on my own at 2020.04.21. There might be grammatical and any other mistakes during the translation and in further content publishing.
