Earlier this spring, we upgraded the infrastructure of the cloud mClouds.ru to the latest Xeon Gold 6254. It's too late for a detailed overview of the processor — over a year has passed since its release, and its specifications are well-known. However, one noteworthy feature is that the processor has a base frequency of 3.1 GHz and 18 cores, which can boost with turbo […]
Network Topology Tasks Create a primary static default route Deploy a floating static route Verify failover to the floating static route when the primary route fails Overview To start, let's clarify what a static route, and even a floating route, is. Unlike dynamic routing, static routing requires building the route manually to a specific network. A floating […]
Hello everyone! Yesterday marked the launch of NEAR, a project my colleagues and I have been working on for the past two years. NEAR is a blockchain protocol and platform for decentralized applications, focusing on performance and ease of use. Today, I want to discuss the problems blockchain protocols solve in today's world, the issues they could address but haven't yet, and where […]
Over the past few years, the price of 2.5-inch solid-state drives has dropped to near that of hard drives. Now, NVMe drives, which operate on the PCI Express bus, are replacing SATA solutions. Between 2019 and 2020, we also observed a decline in the prices of these devices, making them only slightly more expensive than their SATA counterparts. Their main advantage is that such […]
Greetings! Today we will explain how to set up the FortiMail email gateway – a solution by Fortinet for email protection. In this article, we will examine the layout we will be working with, configure FortiMail to receive and verify emails, and also test its functionality. Based on our experience, we can confidently say that the process is very straightforward, and […]
Library Genesis is a true gem of the Internet. This online library, providing free access to over 2.7 million books, has taken a long-awaited step this week. One of the library's web mirrors now allows downloading files via IPFS—a distributed file system. So, the Library Genesis book collection is now uploaded to IPFS, pinned, and connected to search. This means that now […]
Not all server platforms, even the most powerful and scalable ones, meet every need as is. While Kubernetes works great on its own, it may lack the necessary components for completeness. You will always find a use case that ignores your needs or where Kubernetes won't function with the default installation—such as database support […]
From Selectel: This is the second part of the translation of an article about browser fingerprints (you can read the first part here). Today, we will discuss the legality of collecting browser fingerprints of different users by third-party services and websites and how to protect oneself from data collection. So, what about the legality of collecting browser fingerprints? We examined this topic in detail but could not find specific laws (the discussion […]
From Selectel: This article is the first in a series of translations of a very detailed piece about browser fingerprints and how the technology works. Here, we have gathered everything you wanted to know but were afraid to ask about this topic. What are browser fingerprints? This is a method used by websites and services to track visitors. Users are assigned a unique identifier (fingerprint). It contains a lot of information about […]
You may have heard about analysts, machine learning specialists, and artificial intelligence experts, but have you heard about those who are undeservedly overpaid? Meet the data charlatans! These tricksters, lured by lucrative jobs, create a bad reputation for genuine data processing professionals. In this article, we explore how to expose such individuals. Data charlatans are everywhere. Data charlatans are so good at […]
This report focuses on the practical aspects of operator development in Kubernetes, the design of its architecture, and the fundamental principles of its operation. In the first part of the report, we will discuss: what an operator in Kubernetes is and why it is needed; how exactly an operator simplifies the management of complex systems; what an operator can and cannot do. Next, we will move on to discussing the internal structure of the operator. We will examine the architecture and functioning of […]
NetBSD has addressed a vulnerability due to a lack of buffer boundary checks when processing jumbo frames in drivers for USB-connected network adapters. This issue could lead to part of a packet being copied beyond the buffer allocated in the mbuf cluster, potentially allowing an attacker to execute code at the kernel level by sending specific frames from the local network. A fix has been implemented to block the vulnerability […]
