Privilege escalation is the use of the current account's rights by an attacker to gain additional access, typically at a higher level within the system. Although privilege escalation can result from the exploitation of zero-day vulnerabilities, or from sophisticated hackers conducting targeted attacks, or from cleverly disguised malware, it most often occurs due to […]
I frequently encounter developers who have not heard of the SOLID principles (we discussed them in detail here. — Editor) or object-oriented programming (OOP), or who have heard of them but do not implement them in practice. This article describes the advantages of OOP principles that assist developers in their daily work. Some are well-known, while others are less so, and […]
From the translator: We have published an article by Severin Perez on using SOLID principles in programming. The information in the article will be useful for both beginners and experienced programmers. If you are involved in development, you have likely heard of the SOLID principles. They allow programmers to write clean, well-structured, and easily maintainable code. It is worth noting that in programming there are […]

They have stated that they offered an unofficial experimental editor for many years, but now it is about an official product.

However, the topic of dual-screen solutions in […]
Hello everyone. I work as a lead system administrator at OK and am responsible for the stable operation of the portal. I want to share how we established the process of automatically replacing disks, and then how we excluded the administrator from this process and replaced them with a bot. This article is somewhat of a transliteration of my presentation at HighLoad+ 2018 on building the disk replacement process. First, a little […]
The ETL component of the data warehouse often takes a back seat to the warehouse itself and receives less attention than the main database or front-end component, BI, and report generation. However, from the perspective of filling the warehouse with data, ETL plays a key role and requires no less attention from administrators than the other components. My name is Alexander, and I currently administrate ETL at Rostelecom, and […]
I have always believed that a lazy programmer is a good programmer. Why? Because if you ask a hard-working person to do something, they will go ahead and do it. A lazy programmer will spend 2-3 times longer, but will write a script that will do it for them. Perhaps the first time it will take an unjustifiably long time, but with repeated […]
The release of the free cryptographic library Sodium 1.0.18 is now available. It is API compatible with the NaCl (Networking and Cryptography library) and provides functions for secure network communication, hashing, random number generation, digital signatures, and encryption using authenticated public and symmetric (shared-key) keys. The Sodium API emphasizes simplicity and defaults to the most secure options, […]
