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 […]
Good day to everyone! I want to dedicate my debut article on Habr to a very interesting topic – the Internet quality monitoring system RIPE Atlas. Part of my interests includes researching the Internet or cyberspace (the term is rapidly gaining popularity, especially in academic circles).

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.
Last week, in the first part of this article, we described how the Apache and Nginx integration is built in Timeweb. We are very grateful to readers for their questions and active discussions!

Shared hosting implies that multiple sites are hosted on one server […]
The issuance of certificates began on September 16 of last year. Since then, many articles and notes about the new wireless communication standard have been published, including on Habr. Most of these articles focus on the technical specifications of the technology, detailing its advantages and disadvantages. This is all good and as it should be, especially on technical resources. However, we decided […]
One of the most relevant scenarios for using the PVS-Studio analyzer is its integration with CI systems. Although analyzing a project with PVS-Studio can be integrated into almost any continuous integration system with just a few commands, we continue to make this process even more convenient. PVS-Studio now supports converting analyzer output into a format for TeamCity — TeamCity Inspections Type. Let’s take a look at […]
