A new release of the CNC milling machine control system I developed has taken place. This release mainly addresses shortcomings and bugs from the previous version (NoRT CNC Control Release). Improvements: The movement speed scheduler has been redesigned. The new scheduler fully analyzes movement from start to finish, taking into account the curvature of arcs during movement along arcs and selecting the maximum possible […]
The Single Responsibility Principle, also known as the principle of single responsibility or the principle of single variability, is a slippery concept that's often a nerve-wracking question in programming interviews. My first serious encounter with this principle occurred at the beginning of my first year when we, young and inexperienced, were taken to the woods to transform from student larvae into real students. […]
Your deeds are wondrous, Lord. I recently expressed this at a conference dedicated to the theory of generations X, Y, Z. It so happened that all this generational hype passed me by. Therefore, when they started telling me that managing teams requires considering their affiliation to a certain letter of the Latin alphabet, I was a bit puzzled ('surprised', 'astonished', 'dumbfounded', […]

One of the most actively developing trends in gaming is cloud gaming, where a powerful PC or next-gen console is not required to launch a new title. According to analytics agency IHS Markit, last year gaming services […]
One morning, I came across an article about a verifiable random number generator on the Waves platform blockchain. The overall picture was clear, but the method of specific implementation was not. There were codes, signatures, what goes where and why? After several consultations with the oracle's author, I managed to combine the logic of the draw (implemented in PHP) with the algorithm for generating a random number. When the tournament/round started […]
The first milestone test release of the mobile platform Tizen 5.5 has been introduced. This release is aimed at familiarizing developers with the new capabilities of the platform.

The project is being developed under […]
PyPI, the package index for developers using the Python language, has added support for two-factor authentication to protect accounts in case of main password compromise. This feature is available to all registered users of the index. Currently, only time-based one-time passwords (TOTP) generated through a special mobile application are supported as methods of two-factor authentication. One-time password generation can involve […]

In addition to the new measures previously presented […]
This post is dedicated to Children's Day. Any coincidences are purely coincidental. At the age of 10, I got my first computer and a disk with Visual Studio 6. Since then, I've been coming up with little tasks for myself—automating errands, building some web service for three people, or writing a game that will later be removed from the Play Store due to age. Of course, I lost the source codes and […]
In my collection of interesting cases related to online data storage, I came across a noteworthy specimen — today's letter from Crashplan to users of "CrashPlan for Small Business." This specimen will delight tedious skeptics as it confirms their boldest expectations. For optimists and those who have never thought about how online backups work, this may come as a surprise. On May […]
