After NVIDIA demonstrated real-time ray tracing on GeForce RTX series graphics cards, it's hard to doubt that this technology (in a reasonable combination with the rasterization algorithm) is the future of computer games. However, graphics processors based on the Turing architecture with specialized RT cores were considered until recently the only category of discrete GPUs with suitable for...
The developers of the NetBSD project have announced the creation of a new hypervisor and its associated virtualization stack, which are already included in the experimental branch of NetBSD-current and will be offered in the stable release of NetBSD 9. NVMM is currently limited to support for the x86_64 architecture and provides two backends for utilizing hardware virtualization mechanisms: x86-SVM with support for AMD CPU virtualization extensions and x86-VMX for...
We know Solarwinds well and have been working with it for a long time. Many are also familiar with their products for network (and not only) monitoring. However, it is not as widely known that they offer around forty free utilities on their website that can help control network devices, manage infrastructure, databases, and even handle incidents. In fact, this software consists of separate […]
If you're involved in building medium to large Wi-Fi networks, where the minimum number of access points is several dozen, and for larger sites it can be in the hundreds or thousands, you need tools to plan such an impressive network. The results of planning/designing will affect Wi-Fi performance throughout the network's lifecycle, which, for our country, can often amount to around […]
The release of the Bedrock Linux 0.7.3 meta-distribution is available, allowing the use of packages and components from various Linux distributions, mixing distributions within a single environment. The system environment is formed from stable Debian and CentOS repositories, and you can also install newer versions of programs from Arch Linux/AUR, as well as compile Gentoo ports.

In previous articles, we explored what IdM is, how to determine whether your organization needs such a system, what tasks it addresses, and how to justify the implementation budget to management. Today, we will discuss the important steps that the organization must take to achieve the required level of maturity before implementing the IdM system. After all, IdM is designed to automate processes, and automating […]
More good news from 3CX! Last week, two important updates were released: a new VoIP application 3CX for Android and a new version of the 3CX Call Flow Designer (CFD) development environment for 3CX v16. The new 3CX VoIP application for Android includes various improvements in stability and usability, particularly a new […]
Sberbank has announced the implementation of several new features in its mobile application that will help customers save time on visits to branches and finding ATMs. One of the innovations concerns the mobile phone number associated with the bank card: it can now be changed directly through the app — without a visit to the bank. Additionally, it is now possible to set up notifications about transactions. […]
Hello everyone! I work as a DevOps engineer in the hotel booking service Ostrovok.ru. In this article, I want to share our experience testing ansible roles. At Ostrovok.ru, we use ansible as our configuration manager. Recently, we felt the need to test roles, but, as it turned out, there are not many tools for this — perhaps the most popular is the Molecule framework, so […]
The developers of the decentralized messaging system Matrix announced that they are shutting down the servers Matrix.org and Riot.im due to a breach of their infrastructure. It turned out that the servers were compromised twice, and the hackers posted complete information about the server configuration on the project's main page. They also clarified that they copied the database with password hashes of almost five and a half million Matrix users. As proof […]
Hello everyone! I really want to dive straight into the topic, but it'll be more appropriate to share a little about my background: Introduction I am a programmer with experience in developing frontend single-page applications, as well as Scala/Java and Node.js on the server side. For quite a while (definitely a couple — three years), I held the opinion that Docker is a godsend and an amazing tool that absolutely everyone […]
The implementation of any IT solution in an enterprise begins with design. At this stage, the IT manager needs to calculate the number of servers and their specifications, ensuring that there are enough to meet user demand while optimizing the cost-quality ratio of these servers, and that the expenses for creating the computing infrastructure for a new information system do not incur serious […]
