We are developing the most user-friendly* interface for viewing logs

Posted on

If you have ever used web interfaces to view logs, you have likely noticed how bulky and often quite inconvenient and unresponsive these interfaces tend to be. Some you can get used to, and some are simply terrible, but it seems to me that the root of all problems lies in our incorrect approach to the task of viewing logs: we try to create a web interface […]

RIPE Atlas

Tuning PID Controllers: Is the Boogeyman Really as Scary as He's Made Out to Be? Part 1. Single-Loop System

Posted on

This article opens a series focused on automated methods for tuning PID controllers in the Simulink environment. Today, we will explore how to use the PID Tuner application. Introduction The most common type of controllers used in industry for closed-loop control systems can be considered PID controllers. While engineers remember the structure and operating principles of these controllers from their student days, their tuning — that is, calculation — is often a more complex process.

Performance testing of analytical queries in PostgreSQL, ClickHouse, and clickhousedb_fdw (PostgreSQL)

Posted on

In this study, I wanted to examine what performance improvements can be achieved by using the ClickHouse data source instead of PostgreSQL. I am aware of the performance benefits I gain from using ClickHouse. Will these benefits be preserved if I access ClickHouse from PostgreSQL using a foreign data wrapper (FDW)? The database environments under investigation are PostgreSQL v11 and clickhousedb_fdw.
