Oh, the wonderful discoveries that Parallels and Citrix prepare for us! The careless ignorant will suddenly disappear for a moment. This article is a logical continuation of "Comparison of VDI and VPN" and is dedicated to my deeper acquaintance with the company Parallels, particularly their product Parallels RAS. I recommend reading the previous article for a complete understanding of my position. Perhaps some readers […]
In this article, I will attempt to compare two completely different technologies: VDI and VPN. I have no doubt that, due to the pandemic that unexpectedly struck all of us in March of this year, specifically the shift to remote work, you and your company have long made a decision on how to optimally ensure comfortable conditions for […]
The developers of the Chromium project have made a change that sets the maximum lifespan for TLS certificates at 398 days (13 months). This condition applies to all public server certificates issued after September 1, 2020. If a certificate does not comply with this requirement, the browser will reject it as invalid, specifically responding with the error ERR_CERT_VALIDITY_TOO_LONG. For certificates issued before September 1, 2020, trust […]

I work as the CTO at 'Lightning AK,' where we handle IT systems configuration management, utilizing Nextcloud for data storage, including a distributed structure with redundancy. The challenges arising from these installations stem from the large volume of data. […]
Hello! A feature branch (also known as a deploy preview or review app) is when not only the master branch is deployed, but also every pull request is assigned a unique URL. You can check whether the code works in a production environment, and features can be demonstrated to other programmers or product managers. While you are working in a pull request, each new commit removes the current deploy for the old code, and a new […]
By using more modern alternatives alongside older command-line tools, you can enjoy more and even enhance productivity. In everyday Linux/Unix work, we use a variety of command-line tools—such as du for monitoring disk usage and system resources. Some of these tools have been around for a long time. For instance, top was introduced in 1984, […]
What do enterprises extract? Gold, iron ore, coal, diamonds? No! Every enterprise extracts money. This is the goal of every enterprise. If a ton of gold or iron ore does not yield profit or, worse, your costs exceed the income from the sale of products, what value does this ore have for the enterprise? Each ton of ore should generate maximum revenue […]
Hello, Habr! Today we will discuss how to address tasks that typically require human involvement using Azure. Operators spend a lot of time answering the same questions, handling phone calls, and responding to text messages. Chatbots automate communication and recognition, helping to reduce the burden on humans. Bots are also used in Azure DevOps, for instance, to approve […]

However, Sentry enables remote monitoring of bugs. Here you can download the solutions discussed in this article. What is needed If you […]
Hello, Habr! I present to you the translation of the article “The Origins of DevOps: What’s in a Name?” by Steve Mezak. Depending on your perspective, DevOps will celebrate its ninth or tenth anniversary this year. In 2016, the RightScale Cloud Status Report noted that 70 percent of small and medium businesses are adopting […]
