Good day, friends. The second part of the review is coming after the first, and today I am writing a review on the high-level system mentioned in the title. The high-level toolset includes all the software and hardware above the PLC network (we do not include IDE for PLC, HMI, utilities for frequency converters, modules, etc.). The structure of the system from the first part I […]
Good day, dear readers of this article. I am writing this in a review format. A small warning: I want to caution that if you immediately understood what the title refers to, I advise changing the first point (the PLC core itself) to anything from the pricing category one level higher. No savings are worth the amount of nerves it takes, subjectively speaking. For those who are not intimidated by a little gray hair and […]
Companies are announcing artificial intelligence in their automation, discussing how they have implemented a couple of cool customer service systems, but when we call technical support, we continue to suffer and listen to the anguished voices of operators with well-rehearsed scripts. You’ve probably noticed that we in IT are much more perceptive and critical of the work of numerous customer support services from service centers, IT outsourcers, auto services, information services […]
Hello everyone. This is a translation of an article from the book RedHat RHCSA RHCE 7 RedHat Enterprise Linux 7 EX200 and EX300. Personally: I hope this article will be useful not only for beginners but also help more experienced administrators organize their knowledge. So, let’s get started. To access files in Linux, permissions are used. These permissions are assigned to three entities: the file owner, the owner […]
As previously reported, the next major update for the Windows 10 operating system, known as 19H2 or 1909, will begin rolling out to users next week. Overall, it is believed that this update will not bring significant changes to the operating system and will serve as something akin to a regular service pack. However, for enthusiasts, it may be much more important and fundamental, as […]
A significant release of the TensorFlow 2.0 machine learning platform has been presented, providing ready implementations of various deep learning algorithms, a simple programming interface for building models in Python, and a low-level interface for C++, allowing for the management of computation graph construction and execution. The system code is written in C++ and Python and is distributed under the Apache license. The platform was originally developed by the team […]
At the beginning of September, the developers of the Exim mail server informed users about a critical vulnerability (CVE-2019-15846) that allows a local or remote attacker to execute their code on the server with root privileges. Exim users were advised to install an emergency update to version 4.92.2. On September 29, another emergency release, Exim 4.92.3, was published, addressing another critical vulnerability (CVE-2019-16928) that allows […]
I wrote about the Zelenograd company "Telesystems," which produces the world's smallest voice recorders, back in the distant year of 2010; at that time, "Telesystems" even organized a small tour for us at their production facility. The Weeny A110 recorder from the new Weeny/Dime line measures 29x24 mm, weighs 4 grams, and is 4 mm thick. Additionally, the Weeny line also includes even thinner […]
Istio is a convenient tool for connecting, securing, and monitoring distributed applications. Istio employs various technologies for large-scale software deployment and management, including containers for packaging application code and dependencies for deployment, and Kubernetes for managing these containers. Therefore, to work with Istio, you need to understand how an application with multiple services operates […]
The evolution of technology has significantly impacted access control system architecture. By tracing its development, we can predict what awaits us in the near future. The Past Long ago, computer networks were still quite rare. The early access control systems were structured as follows: a master controller serviced a limited number of controllers, while a computer acted as a terminal for its programming and display […]
Microsoft has launched its Windows Virtual Desktop (WVD) service, which allows users to literally run Windows on an Azure virtual machine. The concept of a 'virtual desktop' essentially progresses the trendy notion of streaming gaming and video services, where the client merely needs a low-powered terminal and internet access. The project is noted to have launched globally.
