When the internet appeared in Turkmenistan […]
Hello, Habr. In this article, I would like to share my experience in creating a learning environment for experimenting with microservices. When studying each new tool, I always wanted to try it not only on my local machine but also in more realistic conditions. Therefore, I decided to create a simplified microservice application that can later be 'equipped' with various interesting technologies. The main […]
I created my first websites in the late 90s. Back then, getting them up and running was very simple.

Then you had to enter a username and password and upload files to the server. Those were different times; everything back then […]

Among the numerous UPS options, the most commonly used in entry-level server environments are Smart UPS from APC (now Schneider Electric). Their excellent reliability and low prices in the secondary market mean that system administrators, without much thought, plug these UPS devices into racks and attempt to extract maximum profit from equipment that’s 10-15 years old simply by replacing the batteries. Unfortunately, not always […]
In anticipation of the launch of a new stream for the ‘Data Engineer’ course, we have prepared a translation of interesting material.
