Speculations about Intel potentially implementing hardware acceleration for ray tracing in its upcoming Intel Xe GPU family have been around for quite some time. The company later confirmed this, but only for data center GPUs. Now, clear evidence of ray tracing support in Intel's consumer GPUs has been found in the drivers. A network source with the alias […]
I know many Data Scientists — and I would consider myself one of them — who work on GPU machines, either local or virtual, located in the cloud, whether through Jupyter Notebook or some Python development environment. While working for 2 years as an AI/ML development expert, I did exactly that, while preparing data on a regular server […]
In the Telegram chat @router_os, I often see questions about how to save on purchasing a Mikrotik license or how to use RouterOS for free. Surprisingly, there are indeed legal ways to do this. In this article, I will not address the licensing of Mikrotik hardware devices, as they come with the maximum license that can be supported from the factory […]
A critical vulnerability (CVE-2020-7247) has been discovered in the OpenSMTPD mail server of the developing OpenBSD project, allowing remote execution of shell commands on the server with root user privileges. The vulnerability was identified during a re-audit conducted by Qualys Security (the previous audit of OpenSMTPD was conducted in 2015, and this new vulnerability has been present since May 2018). The issue has been fixed in OpenSMTPD release 6.6.2. All users are recommended to […]
iXsystems has released FreeNAS 11.3, a distribution for quick deployment of Network-Attached Storage (NAS). The distribution is based on the FreeBSD code base, featuring integrated ZFS support and management capabilities through a web interface built using the Python framework Django. Access to the storage can be organized using FTP, NFS, Samba, AFP, rsync, and iSCSI, and software […] can be applied to enhance storage reliability.
Some of us do not use the internet without a VPN for various reasons: some require a dedicated IP, and it is easier and cheaper to purchase a VPS with two IPs than to buy an address from a provider, others want access to all websites, not just those permitted in Russia, and some need IPv6 but the provider does not offer it… Most often […]
Hello everyone, I recently read an old article about speeding up OpenVPN on a router by moving encryption to a separate piece of hardware that is soldered inside the router itself. I have a similar situation as the author — a TP-Link WDR3500 with 128 megabytes of RAM and a poor processor that completely struggles with tunnel encryption. However, I absolutely […]
The Qt Company has announced changes to the licensing model of the Qt framework, which may have a significant impact on communities and distributions using Qt. Starting with version 5.15, LTS branches of Qt will be supported until the next major release is formed, i.e., for approximately six months (updates for LTS branches are issued for three years). This move is expected to accelerate the adoption of new branches and increase the number of […]
Recently, we received LIR status and a /29 block of IPv6. Following this, the need arose to keep track of assigned subnets. And since our billing system is written in PHP, we had to delve into the matter and realize that this language is not the most user-friendly for working with IPv6. Below, we present our solutions for the tasks concerning addresses and […]
Let's talk about eSIM (the full name embeddedSIM — that is, embedded SIM) — SIM cards soldered into gadgets (unlike the usual removable SIM cards). We'll discuss how they are better than traditional SIM cards and why major mobile operators are resisting the adoption of this new technology. This article is written with support from EDISON. We develop applications for Android and iOS, and we can also take on […]
This article is a continuation of the previous one – "Creating a Resilient IT Infrastructure. Part 1 – Preparing for the Deployment of the oVirt 4.3 Cluster." It will cover the process of basic installation and configuration of the oVirt 4.3 cluster for hosting highly available virtual machines, given that all preliminary steps for infrastructure preparation have already been completed. Introduction The main goal of this article is to […]
Intel has disclosed information about two new vulnerabilities in Intel CPUs, caused by data leakage from the L1D cache (CVE-2020-0549, L1DES — L1D Eviction Sampling) and vector registers (CVE-2020-0548, VRS — Vector Register Sampling). These vulnerabilities belong to the MDS (Microarchitectural Data Sampling) class and are based on the application of side-channel analysis methods to data in microarchitectural structures. AMD […]
