The release of project QEMU 4.2 has been announced. As an emulator, QEMU allows you to run a program compiled for one hardware platform on a system with a completely different architecture, for example, running an application for ARM on an x86-compatible PC. In virtualization mode, QEMU's performance for executing code in an isolated environment is close to that of a native system due to direct instruction execution on the CPU and leveraging […]
Good day. It was very interesting to hear Gaël Thomas's opinion (I don't know the transcription) regarding improving programming skills. However, my personal experience suggests that this article misses the most important point. CLOSE HABR AND GO LEARN That's it. The entire secret: we read theory, we practice. We don't read articles about how to learn better or how to be successful. If you […]
Hello, Habr! I present to you the translation of the article "How to improve your programming skills" by Gaël Thomas. Here are the top 5 tips: 1. Set goals for yourself Goal setting increases a developer's productivity. Understand: Why you started programming What your programming goals are What dream you want to achieve by becoming a developer Everyone has personal goals, but I created a list of universal ideas for […]
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 […]
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 […]
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 […]
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 […]
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 […]
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! 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 […]
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: […]
Intel appears to have not yet introduced all of its mobile Comet Lake-U processors. A record of testing the Google Hatch system with the unreleased Core i7-10610U processor was discovered in the Geekbench 5 performance testing database. This processor features four cores and eight threads. The test indicated a base frequency of 4.9 GHz, but it is much more likely that […]
