See the nearly invisible, now in color: a methodology for visualizing objects through a scatterer

Posted on

One of Superman's most famous abilities is his super vision, which allowed him to see atoms, see in the dark and at great distances, and even see through objects. This ability is rarely demonstrated on screens, but it exists. In our reality, seeing through almost completely opaque objects is also possible by applying some scientific tricks. However, the resulting images always […]

How we tested several time series databases

In Russia, special thanks for this go to Yandex and ClickHouse. Until now, if you needed to store […]

The task seemed trivial and did not foreshadow any trouble… Let's begin: 1. We stop and kill all containers of our application: docker-compose down if there are many containers, and they are in […]
