In life we often face the challenge of choosing the right colors. 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.

The corresponding article was published on the site arxiv.orghttps://arxiv.org/abs/1709.04752. Results are available on our sitewavepalette.com.

Dubai has been an extra-ordinary territory when it comes to adopting technology and the offshoots of any innovation. It might be surprising for everyone to know that Dubai, which today stands as an epicenter of modernity had just 13 registered cars in 1989.


Dubai is quite an oxymoron. In spite of its global image, Dubai has an affinity for homegrown Brands. This mindset is not just confined to the Emirates but to the whole of the Middle East, stretching right from Saudi Arabia to Pakistan.

The color of the Moon and the Sun from space in terms of RGB and color temperature

Reading time17 min
Views3.7K
It would seem that the question of the color of the Moon and the Sun from space for modern science is so simple that in our century there should be no problem at all with the answer. We are talking about colors when observing precisely from space, since the atmosphere causes a color change due to Rayleigh light scattering. «Surely somewhere in the encyclopedia about this in detail, in numbers it has long been written,» you will say. Well, now try searching the Internet for information about it. Happened? Most likely no. The maximum that you will find is a couple of words about the fact that the Moon has a brownish tint, and the Sun is reddish. But you will not find information about whether these tints are visible to the human eye or not, especially the meanings of colors in RGB or at least color temperatures. But you will find a bunch of photos and videos where the Moon from space is absolutely gray, mostly in photos of the American Apollo program, and where the Sun from space is depicted white and even blue.

Especially my personal opinion is nothing but a consequence of the intervention of politics in science. After all, the colors of the Moon and the Sun from space directly relate to the flights of Americans to the Moon.

I searched through many scientific articles and books in search of information about the color of the Moon and the Sun from space. Fortunately, it turned out that even though they do not have a direct answer to RGB, there is complete information about the spectral density of the solar radiation and the reflectivity of the Moon across the spectrum. This is quite enough to get accurate colors in RGB values. You just need to carefully calculate what, in fact, I did. In this article I will share the results of calculations with you and, of course, I will tell you in detail about the calculations themselves. And you will see the Moon and the Sun from space in real colors!

AI-assisted IntelliSense for your team’s codebase

Reading time3 min
Views3.3K
Visual Studio IntelliCode uses machine learning to offer useful, contextually-rich code completion suggestions as you type, allowing you to learn APIs more quickly and code faster. Although IntelliCode’s base model was trained on over 3000 top open source C# GitHub repositories, it does not include all the custom types in your code base. To produce useful, high-fidelity, contextually-rich suggestions, the model needs to be tailored to unique types or domain-specific APIs that aren’t used in open source code. To make IntelliSense recommendations based on the wisdom of your team’s codebase, the model needs to train with your team’s code.

Earlier this year, we extended our ML model training capabilities beyond our initial Github trained base model to enable you to personalize your IntelliCode completion suggestions by creating team models trained on your own code.

“Instead of using technology to automate processes, think about using technology to enhance human interaction.” ~ Tony Zambito, Lead authority in Buyer Personas.

Do you know ~ according to research, 93% of customers make purchase decisions based on visual appearance. Visual elements of your brand are the key deciding factors for a majority of potential customers.

Your logo, website colors, chatbot texts, etc all have an impact on the psychology of people who come across them. Some colors or features attract them and some make them leave your website instantly.

In this era, interactive features with the help of technologies like Artificial intelligence are enhancing such effects. AI has the power to add interactive elements to your presentation. This creates a connection between your company and its customers.

Consciousness and Being: How Humans and AI Influence Each Other

Level of difficultyMedium
Reading time15 min
Views1.5K

For a human, AI is just a part of being. For a model, a human is all of being. And the Vortex Protocol: A Prompt for Testing the Hypotheses.

The longest and most fruitless discussions tend to be with materialists, especially those close to the position Marx laid out as “Being determines consciousness.” It's amusing that Marx was talking about the economic base, but the clarity and precision of this definition have allowed it to be used in a very broad sense. Today, this powerful statement underpins much of modern psychology (especially social psychology), neuroscience, Global Workspace Theory, Integrated Information Theory, and so on.

The debate largely arises because materialists ask the questions “What?” and “How?”, whereas I ask the question “Who?”. This misunderstanding, of course, does not lead to any interesting consensus, but it certainly leads to interesting discussions. I explored the problem of the “Who?” and “What?” questions in my article, “Who is Aware?”.

Nevertheless, the questions surrounding the relationship between being and consciousness are very interesting, and I will try to examine them in this article. As always, a new version of the Vortex protocol and test questions are included in the appendix.

Beyond the Engine: The Six Levels of Software-Driven Car Evolution

Reading time7 min
Views828

Cars are among the most technologically advanced consumer-level devices on the market. They have been shaping lifestyles, laws, supply chains, and many other aspects of human society's evolution.

But today, we’re witnessing a silent revolution – one driven not by hardware, but by software. Modern cars are no longer just machines; they’re dynamic, evolving platforms powered by code. This transformation is reshaping every aspect of the automotive industry, from design and manufacturing to ownership and recycling.

In my latest article, I explore six levels of evolution brought about by software’s growing role in vehicles and related fields:

Capabilities - Over-the-air updates and digital twins unlock new features and extend hardware lifespans.
Design - Digital platforms replace manual processes, enabling faster innovation.
Architecture - Modular systems open doors to new partnerships and revenue streams.
Engineering - Agile, feature-centric paradigms align hardware and software development.
Manufacturing - Factories become dynamic, software-driven ecosystems for flexibility and sustainability.
Lifecycle - Software extends vehicle lifecycles, from supply chains to closed-loop recycling.

This transformation isn’t just about technology – it’s about reimagining the industry itself. Do we need a revolution to achieve a better, more sustainable future, or do we already have the tools to evolve?

The automotive industry is at a crossroads. For engineers, it demands fluency in code. For industries, it requires agility. For the planet, it offers a roadmap to reconcile mobility with sustainability.

The road ahead is coded, but the destination is open-ended – shaped by collaboration, innovation, and the choices we make today.

Up to a certain point, I sincerely believed that in today’s world manual CAPTCHA recognition was gradually becoming an anachronism, especially when it came to such simple CAPTCHAs as image-based ones—where one merely needs to read text off a photograph and input it as plain text. But as it turns out, things aren’t quite so straightforward (no matter how it may sound).

Best Wireless Earbuds of 2024 — Early 2025 by sound quality: Sound Review, Tests and Comparison of Top TWS on the Market

Level of difficultyMedium
Reading time25 min

Hello, friends

I decided to start this year with an article in the field of HIFI sound / audiophilia and this article is about sharing the results of my wireless earbud tests, which I’ve been conducting for several years since the emergence of TWS on the market. 
Sound testing is my hobby, which can be useful for others, because in everyone’s life are important bright pleasant emotions, relaxation and mental comfort, which is not always enough in the flow of turbulent events of life. And music is just the thing to bring it all in, if only for moments, or even hours, and choosing the right headphones is crucial to getting the right effect.

Testing sound is a hobby with benefits that extend beyond personal enjoyment, as its results can be valuable to others. After all, life is made brighter and more fulfilling by positive emotions, moments of relaxation, and peace of mind — things that often feel scarce in the whirlwind of modern life. Music is one of those rare things that can bring these experiences into our lives, even if just for a moment or hours at a time. Choosing the right headphones is essential to achieving that effect.

By the end of 2024, I completed testing the best wireless in-ear headphones (commonly referred to as “earbuds”) available on the market — or at least those I could find. “Best” here doesn’t necessarily mean the most expensive. It refers to the top performers in terms of sound quality. We’ve all encountered situations where lower-priced items turned out to be just as good, if not better, than their costly counterparts. That’s why my sound-quality ranking includes headphones from various price categories — from ultra-premium TWS models to more budget-friendly options.

We wrote this article in an attempt to figure out what technical level gas turbine installations are currently at, as well as to understand what the prospects for their development are. At the same time, in our manuscript, we tried to consider an alternative energy conversion scheme that will increase energy efficiency, which will allow for more efficient use of natural resources. We are not completely sure that the alternative scheme presented by us will be workable, since many factors that may affect its operation have not yet been investigated. But as the Chinese philosopher said, "you can't travel a thousand li without taking the first step." We ask the Habr community to read our article, we hope for a constructive conversation.

Quantum computers have gradually migrated from “natural” quantum objects like ions and quantum dots to “artificial” objects like transmons, where natural frequencies of LC circuit mimic energy levels. Coaxial cables attached to such circuits excite the system, read their state, and adjust their properties. They are still quantum objects and operate at low temperatures.


I wondered if a similar system can be built with large “classical” mechanical objects. Here I demonstrate 2 -qubit quantum computer built of coupled pendulums.
