However, it should be noted that […]

In our previous article on cloud topics, we discussed how to protect IT resources in the public cloud and why traditional antivirus solutions are not entirely suitable for this purpose. In this post, we will continue the topic of cloud security, discussing the evolution of WAF and the options available: hardware, software, or cloud. What is WAF? More than 75% of hacker attacks are aimed at […]
The "general euphoria" surrounding blockchain is beginning to wane, writes Kommersant, citing experts. Consequently, investment plans for implementing this technology in Russia have become significantly more modest. According to the draft "roadmap" from Rostec, submitted for approval to the Ministry of Digital Development and the Analytical Center under the Government, approximately 28.4 billion rubles will be allocated for the development of blockchain technologies in Russia by 2024, including […]
This month, Microsoft released the final update for Windows 7, which is no longer supported. It turned out that in some cases, the update disrupts the functionality of desktop wallpapers, turning them into a black background.

It was probably easy to review the first e-books (readers) with screens using "electronic ink." A couple of phrases were enough: "The body shape is rectangular. What can it do? It shows letters." Now, writing such a review isn't as simple: readers have acquired touch screens, adjustable color tone backlighting, word and text translation capabilities, internet access, audio output, and installation options […]

Concerns about data privacy, data leaks, and the growing 'power' of large IT corporations are increasingly troubling not only ordinary internet users but also representatives of various political parties. Some of these, such as supporters of leftist movements, propose radical approaches — from nationalizing the internet to transforming tech giants into cooperatives.

This article is a translation of my article on Medium — Getting Started with Data Lake, which turned out to be quite popular, probably due to its simplicity. Therefore, I decided to write it in Russian and add a bit more detail so that an ordinary person who is not a data specialist could understand what a data warehouse (DW) is and what a data lake […]
The Heisenberg Uncertainty Principle states that one cannot simultaneously measure an object's position and its velocity. If the object is in motion, it has no position. And if there is a position, then it has no velocity. As for microservices on the Red Hat OpenShift platform (and managed by Kubernetes), thanks to suitable open-source software, they can simultaneously report both […]
