The Red Hat OpenShift Container Platform 4 enables the streamlined creation of hosts for deploying containers, including in the infrastructure of cloud service providers, on virtualization platforms, or in bare-metal systems. To create a truly cloud-based platform, we had to strictly control all utilized components and thus enhance the reliability of this complex automation process. […]
(Image by Computerizer from Pixabay) Hello! My name is Evgeny Cherkin, I am a programmer on the development team at the mining company Polymetal. When embarking on any large project, you start to think: 'What software is best to use for its maintenance?'. An IT project goes through a series of stages before releasing the next version. It's great when the chain of these stages is automated. The automated process itself for releasing a new version […]
In this article, we will briefly talk about copyright, but mainly about choosing a free license for the RAD framework IONDV. The framework and for open-source products based on it. We will discuss the permissive Apache 2.0 license, what led us to it, and the decisions we faced in the process. The process of choosing a license is quite labor-intensive […]
Hello everyone! A year ago, I wrote an article about how I organized a university course on signal processing. Judging by the feedback, there are many interesting ideas in the article, but it's large and difficult to read. I have long wanted to break it into smaller parts and write them more clearly. However, rewriting the same thing twice doesn't seem to work. Additionally, […]

The article translation is prepared for students of the 'Linux Administrator' course. Previously, I explained how to check and enable the use of Hugepages in Linux. This article will only be useful if you actually have the opportunity to use Hugepages. I have encountered many people who are misled by the prospect that Hugepages will magically boost performance. However, hugepaging is a complex topic, […]
Go is currently the dominant programming language chosen by people for writing operators for Kubernetes. There are objective reasons for this: There is a powerful framework for developing operators in Go — the Operator SDK. Game-changing applications like Docker and Kubernetes are written in Go. Writing your operator in Go means communicating with the ecosystem in […]
In the previous article, I described the concept and implementation of a database based on functions rather than tables and fields as in relational databases. It included numerous examples demonstrating the advantages of this approach over the classical one. Many found them insufficiently convincing. In this article, I will show how such a concept allows for quick and convenient balancing […]
After participating in the State of the Union session at WWDC 2019, I decided to delve deep into SwiftUI. I spent a lot of time working with it and have now started developing a real application that could be useful to a wide audience. I named it MovieSwiftUI — it's an app for searching for new and old movies and collecting them […]
