Does anyone remember Erwise? Viola? Cello? Let's reminisce. When Tim Berners-Lee arrived at CERN, the famous European particle physics laboratory, in 1980, he was hired to upgrade the control systems of several particle accelerators. But the inventor of the modern web page quickly saw a problem: thousands of people constantly came and went at the research institute, many of whom worked there temporarily. "For programmers on […]
Axel Rietschin, an engineer at Microsoft working on the Windows kernel, has questioned the possibility of developing the ReactOS operating system without borrowing code from Windows. In his opinion, the developers of ReactOS utilized code from the Windows Research kernel, the source texts of which were licensed for universities. Leaks of this code have been published in various environments, including GitHub. Rietschin is confident...
The power of a quantum computer is measured in qubits, the basic unit of measurement in quantum computing. Source. I facepalm after each reading of such phrases. This has not led to good outcomes, my vision is starting to decline; I will soon have to turn to Meklon. I think it's time to systematically summarize the main parameters of a quantum computer. There are several: Number of qubits, Coherence time (decoherence time), Error rate, Processor architecture […]
When visiting any country, it's important not to confuse tourism with immigration. Folk wisdom. Today, I would like to address perhaps the most pressing issue – financial balance while studying, living, and working abroad. In the previous four parts (1, 2, 3, 4.1), I did my best to avoid this topic, but in this article, we will draw a firm line under […]

In this issue, I will show and explain some intricacies of setting up a CMS server in a fault-tolerant cluster mode. TheoryThere are generally three types of CMS server deployment: Single Combined, which means a single server running all necessary services. In most cases, this type of deployment is only applicable for access by internal clients and in small environments, where scalability limitations […]
The Delta Amplon family has a new addition — the manufacturer has introduced a new series of devices with a capacity of 5-20 kVA. The Delta Amplon RT uninterruptible power supplies are characterized by high efficiency and compact size. Previously, this family only offered relatively low-power models, but the new RT series includes single-phase and three-phase devices with capacities up to 20 kVA. The manufacturer positions them for use in […]
