• Beyond the “contact tracing” app

      As a mathematician, it amazes me how much computing power fits on our mobile phones today. Like other «Gen Z» digital natives, I grew up watching people dream up and build technologies that have transformed our social lives, work lives and everything in between.

      Yet in a time when humanity desperately needs innovation more than ever, the application of mobile technologies in the fight against COVID-19 has been weak and fragmented. We have technology literally at our fingertips that could be utilized to help us through this pandemic, but governments around the world have barely managed to develop even a contact tracing app.

        • A Second Check of Newton Game Dynamics with PVS-Studio

            Рисунок 1

            Some time ago, somewhere on the Internet, I stumbled upon a physics engine called Newton Game Dynamics. Knowing that engine projects are usually big and complex, I decided to check its code with PVS-Studio for any interesting defects. I was especially enthusiastic about this one because my co-worker Andrey Karpov already checked it in 2014 and a second check would be a good opportunity to demonstrate our analyzer's evolution over the past six years. As of this writing, the latest version of Newton Game Dynamics is dated February 27, 2020, which means it has been actively developing for the past six years too. So, hopefully, this article will be interesting not only to us but to the engine's developers as well – and for them it's a chance to fix some bugs and improve their code.

                    • How To Open Control Panel On Windows

                      Quite often, I write the following phrase in my articles: ‘Open Control Panel and click Programs’ and then it appears that many users do not know how to open Control Panel in Windows. Moreover, the Programs option is not always available. Let’s close a gap and commit to memory the way you can do it.

                      In this article, I want to show you 5 ways of opening Control Panel on Windows 10 and 8.1. Some of them even work on Windows 7.

                      Please note that most articles provide you with a Control Panel guide with a ‘View By’ option set to icons. However, Windows offers you a Category view by default. For this reason, I recommend that you take into account and change the filter option to Category. It is located in the upper right corner of Control Panel window.

                        For me, these two models are quite similar, but in fact they don’t have obvious characteristics to measure this similarity. These models have different numbers of vertices, edges and polygons. They are of different sizes, rotated differently and both have the same transforms (Location = [0,0,0], Rotation in radians = [0,0,0], Scale = [1,1,1]). So how to determine their similarity?

This happens when we need to choose clothes suitable for each other, shoes suitable for clothes, choose different wallpapers for the children's room, makeup, choose colors for our site and much more. The process of selecting several colors that combine with each other is called the construction of a color palette (gamut).

                              In colouristics there are several methods for constructing a color palette (color gamma) based on the arrangement of colors relative to each other in the color circle and, usually, having the same brightness. Harmonious perception of which is not sufficiently substantiated from the physical point of view.

                              The wave method of building color palette based on the relationship of color and acoustic waves, and also the concept of consonance (harmony) in music theory. Below is a more detailed description of the method.

                              This site allows you to choose the most harmonious combination of colors for your site, clothing, interior, etc.
