If a mobile app or chatbot was also needed, it became even more complicated, and the budget just for the launch […]
Recently, Cloud4Y held a webinar dedicated to the issues of TCO, or total cost of ownership. We received a multitude of questions on this topic, reflecting the audience's desire to understand it better. If you are hearing about TCO for the first time or want to understand how to properly assess the benefits of using your own or cloud infrastructure, it's worth checking it out. When […]
This year, we started a major project to create a cyber range – a platform for cyber exercises for companies from various industries. This involves creating virtual infrastructures that are 'identical to real ones' — so that they replicate the typical internal structure of a bank, an energy company, etc., not only in terms of the corporate segment of the network. We will share more details about the banking and other infrastructures of the cyber range later, and […]
A specialized distribution release of Tails 4.10 (The Amnesic Incognito Live System) has been formed, based on the Debian package base and designed to ensure anonymous access to the network. Anonymous access in Tails is provided by the Tor system. All connections, except for traffic through the Tor network, are blocked by the packet filter by default. For storing user data in the data preservation mode between sessions, […]

Backup refers to storing copies of data somewhere outside the primary storage location. The main purpose of backup is to recover data after loss. In connection with this […]
In the previous publication, we looked at how to create a bot, initialized an instance of the Bot class, and explored methods for sending messages using it. In this article, I continue this topic, so I recommend reading this article only after going through the first part. This time we will figure out how to bring our bot to life and add command support to it […]
In this article, we will use bash, ssh, docker, and nginx to organize a seamless deployment of a web application. Blue-green deployment is a technique that allows instant updates to the application without rejecting any request. It is one of the zero downtime deployment strategies and is best suited for applications with a single instance, but with the capacity to load a second, fully prepared instance alongside it […]
The day of August 24, 1995, marked the official presentation of the legendary Windows 95, which brought graphical user interface operating systems to the masses and made Microsoft widely known. After 25 years, let’s try to understand what made 'the Wind' win the hearts of billions of users around the world. One of the most important features of Windows 95 was that it allowed the operating system […]

Several third-party GUI tools for configuration and workspace implementation are being developed separately […]
The implementation of the ZFS file system in the main branch of FreeBSD (HEAD) has been transitioned to using OpenZFS code, which develops the codebase of 'ZFS on Linux' as the reference version of ZFS. In spring, FreeBSD support was moved to the main OpenZFS project, after which all related changes to FreeBSD continued to be developed there, enabling FreeBSD developers to promptly implement changes into the system […]
