For monitoring servers and services, we have long been using, and still successfully use, a combined solution based on Nagios and Munin. However, this combination has several drawbacks, which is why we, like many others, actively utilize Zabbix. In this article, we will discuss how to address performance issues with minimal effort as the number of metrics being collected increases […]
Testing has begun on the first release candidate for Wine 5.0, an open implementation of the Win32 API. The codebase has been frozen in preparation for the release, which is expected by the end of December or early January. Compared to the Wine 4.21 release, 37 bug reports have been closed and 475 changes have been made. The most significant changes include: The Wine Gecko rendering engine, which is used in the library […]
The release of Zulip 2.1 has been introduced, a server platform for deploying corporate messengers suitable for facilitating communication among employees and development teams. The project was originally developed by Zulip and was made open-source after its acquisition by Dropbox under the Apache 2.0 license. The server-side code is written in Python using the Django framework. The client software is available for Linux, Windows, macOS, Android, and […]
In 2019, every household had heard of Ryzen processors. Indeed, chips based on the Zen architecture turned out to be very successful. The Ryzen 3000 series desktop processors are well-suited both for building a gaming system and for assembling powerful workstations. We see that, when it comes to AM4 and sTRX4 platforms, AMD is practically […]
The task of increasing the communication range with unmanned aerial vehicles (UAVs) remains relevant. This article examines methods to improve this parameter. The article is written for developers and operators of UAVs and is a continuation of a series of articles on communication with UAVs (the beginning of the series can be found in [1]. What affects the communication range The communication range depends on the modem used, antennas, antenna cables, […]
Welcome to a new video course dedicated to Fortinet solutions — Fortinet Getting Started. Throughout this course, I will discuss the company's main solutions within the Fortinet Security Fabric concept and will also demonstrate the operation of two core solutions — the FortiGate firewall and the FortiAnalyzer log storage and analysis tool. The course plan is as follows: […]
Hello! Welcome to the second lesson of the Fortinet Getting Started course. If you are not yet familiar with the course, I recommend viewing the first lesson, which explains the main goals and structure of the course. This lesson is purely theoretical but contains a wealth of useful information: A brief overview of the Fortinet Security Fabric concept and its products; Functional capabilities […]
This article is the second in the series on high-speed data compression. The first article described a compressor operating at a speed of 10 GB/sec per CPU core (minimum compression, RTT-Min). This compressor has already been implemented in forensic duplicator equipment for high-speed compression of data carrier dumps and enhancing cryptographic resilience; it can also be used for compressing virtual machine images and […]
Dear friends, I’m glad to see you again. I personally really missed our communication. My long absence from this resource was due to an extremely high influx of patients. Among them, I am pleased to note, were many readers of my previous articles. And even, I dare say, commentators! The occasion that inspired me to pick up the pen once again was the fact that […]
After a year of development, the release of the spam filtering platform — SpamAssassin 3.4.3 is now available. SpamAssassin implements a comprehensive approach in determining whether to block a message: the message undergoes a series of checks (context analysis, black and white lists DNSBL, trainable Bayesian classifiers, signature checks, sender authentication via SPF and DKIM, etc.). After evaluating the message through various methods, a certain weight is accumulated […]
Hello, users of Habr! I present to you a translation of the article 'What is NFC and how does it work' by Robert Triggs. It seems strange that the original author would write about this topic in 2019, and I would translate it on the threshold of 2020. Today, NFC has taken on a real-life application and is no longer just a geeky technology for token key fobs. Now it’s also […]
Recently, such job postings have flooded the internet. Despite the attractive salary, it’s hard to ignore the bizarre nonsense written inside. Initially, it seems like 'DevOps' and 'engineer' can somehow be glued together into one word, followed by a random list of requirements, some of which are clearly copied from a sysadmin vacancy. In this post, I’d like to discuss a bit about how we […]
