Natron 2.3.15

A new version of the Natron software has been released, designed for compositing special effects with video for film production (the closest commercial analogs of the project are The Foundry Nuke and Blackmagic Fusion). In the two years since the last release, the project was nearly shelved due to conflicts among the main developers. However, work has resumed. The new version primarily includes fixes and […]

In the beta version of Android 11, the payment service Google Pay does not work.

After several months of testing the preliminary builds, Google has released the first beta version of Android 11. Generally, beta versions are more stable than preliminary builds, but they are not without flaws; therefore, they are not recommended for everyday users. According to network sources, Google Pay does not work in the first beta version of Android 11, so it is better to refrain from installing the OS if […]

The OpenZFS project has removed the mention of the word 'slave' from its code due to political correctness.

Matthew Ahrens, one of the two original authors of the ZFS file system, has cleaned up the source texts of OpenZFS (ZFS on Linux) by removing the term "slave," which is now considered politically incorrect. According to Matthew, the repercussions of human slavery continue to impact society, and in modern contexts, the term "slave" in computer programs serves as an additional reminder of an unfortunate human experience. […]

Zephyr 2.3.0

The release of RTOS Zephyr 2.3.0 has been introduced. Zephyr is based on a compact kernel designed for use in resource-constrained systems and embedded systems. It is distributed under the Apache 2.0 license and is supported by the Linux Foundation.

A Deep Dive into the Principles of Wi-Fi 6: OFDMA and MU-MIMO

In its developments, Huawei is focusing on Wi-Fi 6. Questions from colleagues and clients regarding the new generation of the standard prompted us to write a post about the theoretical foundations and physical principles underlying it. We will transition from history to physics, thoroughly examining the necessity of OFDMA and MU-MIMO technologies. We will also discuss how the fundamentally redesigned […]

OpenShift virtualization: containers, KVM, and virtual machines

OpenShift virtualization (upstream project – Kubernetes: KubeVirt, see here and here), originally known as Container-native Virtualization, has been introduced as a feature of the OpenShift platform designed for deploying and managing virtual machines (VMs) as fundamental entities of Kubernetes. This type of task is technically complex due to the fundamental differences in technologies. To achieve the set goals, familiar […]

Remotely exploitable vulnerability in the GNU adns library

In the developing project GNU library for performing DNS requests, adns, seven vulnerabilities have been identified, four of which (CVE-2017-9103, CVE-2017-9104, CVE-2017-9105, CVE-2017-9109) can be exploited to conduct remote code execution attacks on the system. The other three vulnerabilities lead to denial of service through the crashing of applications using adns. The adns package includes a C library and a set of utilities for […]

ARM has leaked: an exceptional vulnerability has been discovered for speculative execution attacks

For processors across a wide range of Armv8-A architectures (Cortex-A), a unique vulnerability has been identified for side-channel attacks utilizing speculative computation algorithms. ARM has reported this and provided patches and guidance for mitigating the identified vulnerability. The risk is not overwhelming, but it should not be ignored, as processors based on ARM architecture are everywhere, making the risk of leaks […]

Two-factor authentication for VPN users via MikroTik and SMS

Hello colleagues! Now that the excitement around remote work has calmed down a bit, and most admins have successfully enabled remote access for employees to the corporate network, it's time to share my long-standing approach to enhancing VPN security. This article will not cover the currently popular IPSec IKEv2 and xAuth. Instead, we'll discuss building a two-factor authentication (2FA) system for VPN users, with MikroTik serving as the […]

Comparison of platforms for 1C development and Client Communicator

In this article, I will discuss 1C and КлиК not as ready-to-implement solutions, but as platforms for creating customized solutions. 1C Client Communicator Free versions are not available. A free educational version is available with many different limitations. Any configuration can be used in single-user mode for free and without restrictions. Installation File version (not recommended for network use): […]
