Every newly created system is unstable. Is it impossible to accept it or not? Remember the first airplanes — they were unreliable and, as a result, unpredictable. In 1903, the Wright brothers lifted their plane into the air for about 12 seconds. In 1908, one of the demonstration flights ended in the death of a passenger. At the beginning of the 20th century, accidents were commonplace. But everything has changed, and thank God.

We interviewed specialists from several dozen companies. Here are the most meaningful answers.

Starting July 1, 2025, the voltage standard in the electrical network will officially change in Ukraine. What does this mean for consumers? Do I need to change my devices? And who is responsible if the voltage «jumps»? Let’s break it down point by point.

Ukrainian business has repeatedly tried to abandon 1 °C. Dozens of «Ukrainian alternatives», information campaigns, but it still remains the main accounting system at most Ukrainian enterprises. What is the real reason for this «resistance» to change? Is it just a lack of modern solutions or caution on the part of business? In fact, the problem is deeper. It is rooted in traditional approaches to management that have been formed over the years. And these approaches do not automatically change with the transition to a new, even more modern product, but with the same functionality.

The massive attacks that the enemy is carrying out on Ukraine are becoming more frequent. In particular, the capital of our country has recently been experiencing significant destruction: missile strikes on residential buildings, combined strikes, fires. In addition to various shelters arranged in public places, almost two years ago, woodworking equipment manufacturer Serhiy Zakharin developed and began manufacturing a metal structure for the «Life Capsule» shelter, which can be installed inside an apartment, house, or office. He told dev.ua what is currently happening with production, how large-scale shelling affects the process and volumes, and what changes the capsules may undergo.

OnlyFans models who received notices from tax authorities about additional tax assessments of hundreds of thousands of hryvnias are appealing these notices-decisions in court.

Japan this week executed the «Twitter Killer» who killed nine people in 2017. It is the first use of the death penalty in the country since 2022.

A Ukrainian student team of four specialists founded the startup ExactOptiRoute and is developing a web application that allows you to travel around the center of Kyiv. The developers used operations research and artificial intelligence methods that allow the user to build unusual routes to visit not only historical and architectural monuments, but also enjoy delicious locations, see parks, and get to other useful and interesting places in the capital. The startup’s CEO, 23-year-old Mykola Korablev, told dev.ua what’s special about the application and how it differs from Google Maps.

Since artificial intelligence has become part of workflows, teams have a new set of tools to work more efficiently. It would seem that under such conditions, management should become simpler and the quality of management should increase.

“This is already a must-have, there are already cases where engineers are asked to write online coding prompts during interviews,” is one of the comments we saw on LinkedIn. It was written by Software Developer Viktor Svertoka after discussing such cases with colleagues during a meeting at the DOU Day IT conference. So we decided to ask team leaders whether they practice such a task, and vice versa — we asked developers whether they have encountered such a requirement. In addition, we monitored vacancies on jobs.dou to check how often employers require candidates to have such a skill. Here is what our small study showed.

Blockchain is a distributed ledger of data, the main feature of which is its complete independence from any centers. At the heart of this independence is cryptography, which ensures the authenticity and immutability of records, as well as decentralization, which eliminates the need for a central management body. But while the concept of encryption is understandable at a basic level, the question of implementing the second mechanism remains a mystery to most people.

For a very long time, the specialization of a tester was positioned as the easiest and fastest way to enter IT. And still, some courses and schools periodically speculate on this issue. However, it has already become clear to many that everything is not so simple and unambiguous. In addition, artificial intelligence is developing rapidly, thanks to the tools of which certain transformations are also observed in the work of testers and approaches to the selection of candidates. Serhiy Romanov, a tester with over 15 years of experience who currently works for Ukrainian company Brightgrove, which collaborates with streaming giant Pluto TV, owned by Paramount Global, shared with dev.ua his observations on changes in QA, as well as tips on AI tools and examples of how AI can be used in testers’ work, which can both help and threaten.

Over the past few decades, Ukrainian women have proven that their place and role in the domestic IT sector are beyond doubt. If we take the statistics from February 2024 to February 2025, then among new IT entrepreneurs, women generally made up 48%, almost embodying the same gender equality in practice. But is there a place in Ukrainian IT for purely female projects, which, moreover, declare themselves on the market with a slight touch of shocking? The girls from Sisi.Dev prove that yes. We spoke with Founder and Project Manager Yulia Mazhaeva, Co-founder and Head of UI/UX design Khrystyna Moroz, and Business Development Manager and Marketing specialist Alena Kukhtina to understand what services Sisi.Dev provides, what domains they work with, and what it’s like to run a women’s business during a full-scale war. In a conversation with dev.ua, they also told us how it all started, what business development plans they have, and how customers are reacting to their somewhat provocative «sign.»

Can player safety be developed through the architecture of IT solutions? Sweden and Finland have long stopped accepting responsible gaming as an option — it is a full-fledged ecosystem in which data, behavioral scenarios, and response algorithms work in anticipation.

Hello! This is Oleksandr Kryvotsyuk from «Just About Marketing», and in this article I want to share my own experience of building marketing in IT. Building a marketing department in an IT company is a complex process that requires a clear understanding of the industry, proper budgeting, and a strategic approach. Many companies simply don’t know where to start, which specialists to hire, and how much money to invest.

Since 2024, Ukrposhta has introduced the international practice of selling parcels that have been undelivered and unused for six months at auction through the Prozorro.Sales platform. The company explained how to participate in such auctions.

Hello, marketers and everyone looking for new ways to get closer to the customer! I know the word «personalization» sounds like a cliché from marketing presentations. But things are different now. Not because new ways of collecting data have emerged, but because the user’s mindset has changed — and decisions are often made not by a person, but by their AI-based agent. Have you talked to ChatGPT about buying a new laptop? Or asked Perplexity for advice on a Tesla alternative? If so, congratulations—you’ve experienced the beginning of the biggest marketing transformation since SEO.

The digital era has opened up a lot of advantages for us: the ability to buy anything, anytime and from anywhere, instead of wasting time traveling. Now you can quickly order the desired item to your home. However, cyberspace is an environment in which you need to be constantly attentive, because scammers can take advantage of your carelessness and lure confidential information, and with it, money. So, let’s look at how to shop online safely: without financial and information losses.

If your business isn’t ranking on Google Maps, you’re not alone. Thousands of businesses face the same problem every day. But here’s the truth: getting to the top isn’t as difficult as it seems, as most of the top positions are occupied by businesses that are easy to bypass.

A team of Ukrainian schoolchildren led by a 15-year-old CEO has created an augmented reality mobile application called Firselp, which teaches users how to provide first aid in critical situations. Project leader Dmytro Palamarchuk, who just finished 9th grade, told dev.ua about the service, which aims to make basic first aid knowledge accessible, understandable, and effective even during times of stress.

Despite all the rich epithets about self-development, vocation, team atmosphere, and «kindred spirit,» the main motivator in any job remains salary. Its timely and full payment is the «base.» And if this condition is violated, not everyone will want to continue working with such an employer. But what to do when salary debts accumulate, but it seems like no one is thinking of paying them? Everyone has the right in this situation to go to court, but this involves a lot of time, expenses (after all, it is difficult to cope on your own without a lawyer) and nerves, so not everyone goes this route.

How AI helped me find my dream job: the real experience of a top manager from Silicon Valley.
