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.

On 17.10.2024, the article “A new inherent approach to solving the Collatz 3n+1 problem and its analogues” was published on the Academia.edu website [1]. The second link is for those who find it easier to read in Russian “Новый внутренне присущий подход к решению проблемы Коллатца 3n+1 и ее аналогов” [2].
The English version was originally intended for the arXiv preprint platform, but they suggested first publishing in a peer-reviewed mathematical journal. Attempts to access other platforms HAL, Qeios, and ResearchGate were met with the requirement for affiliation, which an independent researcher does not have.
The process took almost two months — more than the research itself from idea to text. As a result, the article ended up on the Academia site, which is free from “face control”. I think it will be useful for anyone interested in the Collatz conjecture to read it. Exclusively for Habr, this short text summarizing the content and meaning of the publication.

Hey there! I'm excited to share some big news from Google about their latest AI model, Gemini 2.0. I encourage you to read the article till the end and watch my video demo. It's mind-blowing!

Any SEO expert knows the pain of collecting Google keyword data. It’s one thing if you can count all the queries on one hand, but what if they number in the thousands? How do you check the search volume in Google for each keyword? Frankly, once you hit tens of thousands of keywords, it’s enough to make your head spin. You’ll be tempted to reach for outdated, familiar tools, only to find modern reality throwing a curveball: the old formula of Key Collector + Google Ads + a few proxies simply doesn’t cut it anymore. We’re entering a new era, and without direct access to the official API, things get grim and complicated fast.

In the fast-paced world of software development, ensuring the quality and reliability of applications is crucial. With the ever-increasing complexity of software systems, it becomes essential to adopt a comprehensive and structured approach to testing. One such approach can be encapsulated in the acronym "RABBIT," where each letter stands for a distinct branch of testing. This multifaceted strategy covers various testing methodologies that together create a robust framework for quality assurance. This article explores each branch of RABBIT testing in detail, providing insights into their significance, implementation, and appropriate use cases.

Gen Z – a generation of young people born between the last few years of the 20th century and the first ten years of the 21st, are the primary users of a modern-day Internet. They started using technology since their early childhood, being almost constantly glued to their smartphones and tablets, which led to them being very demanding users that have their own requirements in UX. At the same time, they are known for their sense of humor and straightforwardness – which means they love using products that are both easy to navigate but full of interactive elements. Below we’ve collected a few things you should consider when creating a UX design aimed at a young audience.

SSH (Secure Shell) is the backbone of remote system administration and secure remote access, serving millions of developers and system administrators daily. However, when SSH connections fail, the cryptographic nature of the protocol can make debugging challenging. The complex interplay between authentication mechanisms, encryption algorithms, and network layers often obscures the root cause of connection issues. This complexity is further compounded by the protocol's security-first design, where error messages are intentionally vague to prevent potential attackers from gathering system information. Whether we're dealing with key authentication failures, network connectivity issues, or configuration mismatches, understanding the underlying SSH architecture becomes critical for effective troubleshooting.

In today's interconnected development world, secure authentication is not just a luxury—it's a necessity. Whether you're a seasoned DevOps engineer or a junior developer just starting your journey, understanding SSH key pairs is crucial for your daily workflow. They're the unsung heroes that keep our git pushes secure, our server access protected, and our deployments safe from prying eyes.
But let's be honest: SSH keys canbe confusing. With terms like “public key infrastructure,” “cryptographic algorithms,” and “key fingerprints” floating around, it's easy to feel overwhelmed. This guide aims to demystify SSH key pairs, breaking down complex concepts into digestible pieces that will help you make informed decisions about your security setup.
