Happy Friday everyone! Friends, today we continue our series of publications dedicated to the 'DevOps Practices and Tools' course, as classes in the new group will start at the end of next week. So, let's get started! Monitoring is simple. This is a well-known fact. Raise Nagios, run NRPE on a remote system, configure Nagios to the NRPE TCP port 5666, and you have...
Google has published a study titled 'How Effective Is Basic Account Hygiene in Preventing Account Theft', which outlines what account owners can do to prevent theft by malicious actors. We present you with a translation of this study. However, the most effective method used by Google itself was not included in the report. I had to write about this method at the end...
Google and Binomial have released the source code for Basis Universal, a codec for efficient texture compression, along with its universal file format '.basis' for distributing image and video-based textures. The reference implementation code is written in C++ and is provided under the Apache 2.0 license. Basis Universal complements the previously published Draco 3D data compression system and aims to address...
In the world of Postgres, indexes are crucial for effective navigation through the database storage (referred to as the 'heap'). Postgres does not support clustering for it, and the MVCC architecture leads to the accumulation of many versions of the same tuple. Therefore, it is essential to be able to create and maintain efficient indexes to support applications. I present to you […]
Kubernetes Dashboard is a user-friendly tool for obtaining current information about a running cluster and providing minimal management. You appreciate it even more when access to these capabilities is needed not only by administrators/DevOps engineers but also by those who are less accustomed to the console and/or do not intend to deal with all the intricacies of interacting with kubectl and other utilities. Thus it happened […]

Among the reasons for this downturn are the complexities of device design processes and a lack of automation. A few years ago, engineers from Intel noted that when creating high-performance […]
It took developers of ZFS on Linux (abbreviated as ZoL) about two years and 5 RC releases to produce a highly significant release — ZFS-0.8.0. New features include 'native' encryption for both file systems and volumes. The aes-256-ccm algorithm is used by default. Keys for the dataset are managed using the 'zfs load-key' command and related subcommands. Encryption during zfs send/receive. This allows for the storage of backups […]
This article does not cover the full setup of DPI and everything related to it, and the scientific value of the text is minimal. However, it describes a simple method for bypassing DPI that many companies have overlooked. Warning #1: this article is exploratory in nature, does not encourage anyone to take action, and is not intended for use. The idea is based on personal experience, and any coincidences are purely accidental. Warning #2: […]
The Audi e-tron electric car, which is the first fully electric vehicle from the German company, received a high safety rating from the European New Car Assessment Programme (Euro NCAP) after conducting crash tests. Currently, Euro NCAP is the primary organization that evaluates vehicle safety based on independent crash tests. The safety rating for the Audi e-tron electric car turned out to be more than positive. Safety […]

As for those who are already familiar with Part 1 — let's get down to business. Yes, and I know that for many, Friday has just begun — so here’s a reason to prepare for the evening. […]
After nearly two years of development, ZFS on Linux 0.8.0 is released, implementing the ZFS file system as a module for the Linux kernel. The module has been tested with Linux kernels from 2.6.32 to 5.1. Ready installation packages will soon be prepared for major Linux distributions, including Debian, Ubuntu, Fedora, RHEL/CentOS. The ZFS on Linux module is already included […]
Hello, colleagues! In the previous material, we got acquainted with a useful and, as you might notice, quite necessary element of VoIP infrastructure—the traffic monitoring system, or SMT for short. We learned what it is, what tasks it solves, and also noted the most prominent representatives presented to the IT world by developers. In this part, we will explore the principles by which SMT is implemented in IT infrastructure […]
