Yulia Buglak is the founder of one of the most unusual Ukrainian startups that clearly stood out at this year’s IT Arena. Fiskin makes luxury accessories from fish skin (!) — in particular, the startup’s website presents women’s bags, cardholders, bracelets and watch straps made from this unusual material for the general public. This is not a cheap pleasure — for example, a fish skin bag will cost over 66 thousand UAH, and a cardholder — over 7,000 UAH, but the brand is positioned as luxury.

Previously, the first snow or frost always came as a surprise — despite the calendar, forecasts, and warnings. As a result, people were suddenly stuck in queues for tire fitting. Something similar is happening today with preparations for blackouts. For three years in a row, Russia has been systematically attacking Ukraine’s power system, and every year we enter the blackout season again. For Ukrainians, this is a new reality that needs to be treated with caution.

This year’s winter will be the hardest for Ukrainians since the beginning of the Great War. Such headlines abound in international media, and statements of similar content continue to pour from the lips of energy experts and officials. According to experts, Russian strikes on CHP plants and infrastructure could lead to local and regional power and heat outages. However, the probability of a mass complete «national blackout» is still considered low, it is worth preparing for dozens of hours without light and heat now. The head of Ukrenergo Vitaliy Zaychenko believes that Ukrainians need to prepare for the fact that the situation can change very dynamically. «In these conditions, it is quite difficult to guarantee that there will always be light. We need to prepare for the fact that the situation can change very dynamically,» the head of Ukrenergo emphasized. According to him, «the enemy is particularly furious and systematically attacking all energy and heat-generating facilities simultaneously. Massive attacks with drones, missiles. It is doing everything to destroy and destroy critical infrastructure.» dev.ua has collected 10 questions and answers about what is happening in the energy system and how to get through the current winter as comfortably as possible.

Everyone has long known how building a company through the system of individual entrepreneurs (hereinafter referred to as «FOP») works, but I want to highlight why, in my opinion, this model still prevails, using the example of a comparison with the state alternative in the form of «Diya.City».

Quantum computing is becoming a reality and will soon be able to solve problems that far exceed the capabilities of today’s fastest supercomputers. However, in the hands of cybercriminals, quantum computers will also create a new level of challenges for cybersecurity professionals. To protect data, governments and businesses need to start the transition to post-quantum cryptography in advance, without waiting for the emergence of affordable powerful quantum computers. The European Union has already started to act in this direction — in early 2026, the EU-supported Quantum-Resistant Cryptography in Practice project will start with the participation of 11 countries.

One of the first questions that arises for a person who is starting to understand the crypto world is: where are the coins actually stored, if not in a cryptocurrency wallet?

In my last blog, I talked about what and how payment routing works. Let me remind you that in the previous series: payment routing is the process of constructing routes (hence routing), within which the maximum number of payments (preferably all) will successfully pass through the most reliable and fastest route. To imagine how this happens, just draw an analogy with the need to let dozens of trains go in different directions. It will take a lot of time on one track, but if there are three tracks, the process will go quickly — but where will which train be sent? The schedule and the route map are routing. But here is the instruction on where trains should go if there is an accident or technical work is being carried out in the world of payments called smart retry. We will talk about it today.

Hello! It’s #vsrativakansii again. Autumn is in full swing, candidates are still complaining about the difficult job search, recruiters can’t find worthy candidates. In short, the labor market lives its own life despite the cold, shelling and blackouts. Today we’re talking about strange vacancies and a little bit about shitty candidates.

In battles on LinkedIn and other professional platforms, candidates and recruiters are constantly «breaking spears» over who is to blame for the current situation on the technology job market. Meanwhile, hundreds of comments under posts and mutual teasing (at best) or humiliation (at worst) do not improve the situation. A well-known IT expert, Sergey Alekseev, is sure that the problem is that existing tools do not allow candidates to truly reveal themselves, but force them to send hundreds of faceless CVs like robots. Recruiters, accordingly, simply drown in the information avalanche and lose the best candidates in this chaos. To find a way out, Alekseev proposed his own product, which he worked on alone for a year — the MyPitch AI platform. Recently, he made an important decision — to fully focus on this project and expand the team.

The technical sphere is at a turning point: the usual methods still work, but artificial intelligence is constantly influencing their renewal and adaptation. In recent years, the pace of change has only increased, and if you look closely, you can see it everywhere. For example, according to the McKinsey State of AI 2025 study, 75% of businesses have already integrated AI into at least one function, and 92% plan to increase investments in the next three years. An assistant in the form of an AI assistant is the reality of most technical teams. I believe that even more significant transformations await us. Should we be afraid of them and what to expect?
