If you search Google for the phrase 'kubernetes apply vs replace', you will find an answer on StackOverflow that is incorrect. When searching for 'kubernetes apply vs patch', the first link is the documentation on […]
Hello everyone! As part of my coursework, I researched the capabilities of a domestic cloud platform, Yandex.Cloud. The platform offers various services to address practical tasks. However, sometimes it is necessary to configure your cloud application with a sufficiently complex infrastructure based on these services. In this article, I want to share my experience in deploying such an application. What do I want to achieve? Grafana — […]
The release of the Python scientific computing library NumPy 1.19 is now available, focused on working with multidimensional arrays and matrices, and providing a large collection of functions that implement various algorithms related to matrix usage. NumPy is one of the most in-demand libraries used for scientific calculations. The project's code is written in Python with optimizations in C and is distributed […]

Data leaks are a significant concern for security services. Now, with most people working from home, the risk of leaks is much higher. This is why well-known cybercriminal groups are paying increased attention to outdated and insufficiently protected remote access protocols. Interestingly, an increasing number of data leaks today are related to Ransomware. How, why, and in what ways — read […]

The results of a study on the impact of thousands of the most popular Chrome extensions on browser performance have been published. It has been shown that some extensions can significantly affect performance, create a heavy load on the system, and increase memory consumption several times. The testing assessed CPU load in active and background modes, memory usage, and its effect on rendering speed […]
While developing a solution for a client, two tasks arose that I wanted to solve elegantly using Zabbix's standard functionality. Task 1: Monitoring the current firmware version on Mikrotik routers. This task is easily accomplished by adding an HTTP agent to the template. The agent retrieves the current version from the Mikrotik website, while a trigger compares the current version with the actual one and issues an alert if there's a discrepancy. When […]
According to statistics, the volume of network traffic increases by about 50% each year. This leads to an increase in the load on equipment and, in particular, raises the performance requirements for IDS/IPS. You can purchase expensive specialized hardware, but there’s a cheaper option — implementing one of the open-source systems. Many beginner administrators believe that installing and configuring a free IPS […]
The developers of the LLVM project have expressed their intention to follow the example of other projects and stop using the word "master" to identify the main repository. This change is presented as a demonstration that the LLVM community is inclusive and sensitive to issues that may cause discomfort to certain groups of participants. Instead of "master," it is proposed to choose a neutral alternative, such as "dev," "trunk," "main," or "default." It is noted that […]
