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 […]
Correction updates have been released for stable branches of the DNS server BIND 9.14.4 and 9.11.9, as well as for the experimental branch 9.15.2 currently in development. The new releases address a vulnerability (CVE-2019-6471) caused by a race condition that could lead to a denial of service (process termination upon assertion failure) when blocking a large number of incoming packets. Additionally, the new version 9.14.4 introduces support for the GeoIP2 API […]
Recently, I came across a not-so-popular creature in the world of DevOps, Azure DevOps pipelines. I immediately felt the lack of clear instructions or articles on the topic. I don't know what this is related to, but Microsoft clearly has work to do in promoting the tool. Today, we will build a pipeline for automated testing within the Azure cloud. So, […]
The world of databases has long been dominated by relational DBMS that use SQL. It's so pervasive that the emerging varieties are called NoSQL. They have managed to carve out a niche in this market, but relational DBMS are not going anywhere and continue to be actively used for their purposes. In this article, I want to describe the concept of a functional database. For better understanding, I […]
Microsoft is working on a new global control for multimedia in its Edge browser based on Chromium. Reportedly, the control activated by clicking the 'Multimedia' button in the address bar will now be able to display not only a list of currently playing audio or video files but also other active multimedia sessions, which can then be switched between and managed individually.

In accordance with the amendments to the law 'On Communications' in Kazakhstan that have been in effect since 2016, many Kazakh providers, including Kcell, Beeline, Tele2, and Altel, have today implemented systems to intercept clients' HTTPS traffic by substituting the originally used certificate. Initially, the interception system was planned to be implemented in 2016, but this operation has been constantly delayed, and the law has already become […]

P4 is a programming language designed for programming packet routing rules. Unlike general-purpose languages like C or Python, P4 is a domain-specific language with a number of constructs optimized for network routing. P4 is an open-source language licensed and supported by a non-profit organization called the P4 Language Consortium. It is also supported by […]
You may be familiar with OSINT and have used the Shodan search engine, or you might already be using a Threat Intelligence Platform to prioritize IOCs from various feeds. However, sometimes it is necessary to constantly view your company from an outside perspective and receive assistance in addressing identified incidents. Digital Shadows allows you to monitor your company's digital assets, and its analytics provide actionable insights. Essentially […]
This article aims to explore the possibilities of transparent proxying, which allows for the seamless redirection of all or part of the traffic through external proxy servers without clients noticing. When I began to tackle this task, I encountered a significant issue with implementation — the HTTPS protocol. In the good old days, there weren't many problems with transparent proxying of HTTP, […]
In large groups of people, a leader always emerges, whether consciously or not. The distribution of power from the highest to the lowest levels of the hierarchical pyramid has several advantages for the group as a whole and for individual members. After all, order is always better than chaos, right? For thousands of years, humanity has implemented a power hierarchy in various civilizations in diverse ways […]
