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 […]
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 […]
Microsoft Exchange is a comprehensive tool that includes email reception and processing, as well as a web interface for your mail server, access to corporate calendars, and tasks. Exchange is integrated with Active Directory, so let’s assume it has already been deployed. Meanwhile, Windows Server 2019 Core is a version of Windows Server without a graphical interface. In […]
Hello, habr. If someone is running the graphite-web system and has encountered performance issues with the whisper storage (IO, disk space consumption), the likelihood of having looked at ClickHouse as a replacement should approach one. This statement implies that a third-party implementation, such as carbonwriter or go-carbon, is already being used as the metric receiver. ClickHouse addresses […]
Regarding the searches at nginx's office and the arrest of Igor Sysoev, a detailed analysis has already been made on Habr. I'm discussing the same topic, but from a different perspective… What is happening, folks? Look at how journalists have rallied behind Golunov. Are we any worse? This is utter madness, or just pure disgrace. It seems like the lines have been blurred, […]
Translated note: Service mesh is a phenomenon that still lacks a stable translation into Russian (over 2 years ago, we suggested the term 'service grid', and later some colleagues began promoting the combination 'service sieve'). Ongoing discussions about this technology have led to a situation where the marketing and technical components are too closely intertwined. This remarkable […]
In the previous part of the "Introduction to SSD" series, we covered the history of disk drives. The second part will discuss the interfaces used to interact with storage devices. Communication between the processor and peripheral devices occurs according to predefined agreements known as interfaces. These agreements regulate the physical and software levels of interaction. An interface is a set of tools, methods, and rules governing the interaction between system elements. […]
One of the main tasks in building large-scale Zimbra OSE infrastructures is effective load balancing. In addition to enhancing the service's redundancy, load balancing is essential for ensuring consistent responsiveness across all users. To address this task, load balancers — both software and hardware solutions — are employed to redistribute requests among servers. Among these, there are both very […]
On December 9, the latest version of Kubernetes was released — 1.17. Its motto is 'Stability,' with many features achieving GA status and a number of deprecated features being removed... As always, our favorite Action Required section of the CHANGELOG-1.17.md file demands attention. Let's get to work... Attention, Storage! Live kubelet updates in version 1.17 are not supported due to changes in the path […]
