Tesla has become a laughing stock even among its loyal fans: the last car it released completely failed, both in quality and sales, and the company's main ideologist has become so unhinged in American politics that he has turned from a favorite of the public into an antagonist. dev.ua tells about the difficult path of Tesla Motors, which, contrary to forecasts, became the hegemon of the electric car market, but has descended to the arson of its own car dealerships by ordinary citizens.

In today’s dynamic world, there are specialists who have already reached the senior level in their specialty by the age of 25, having worked almost since school or since the beginning of their studies at a university. Surprisingly, not everyone likes this. However, this fact cannot be ignored. Diana Koval, 23, from Dnipro, has been working since she was 17 and is now a Senior Software Engineer (React.js). The girl is surprised to hear about conversations where specialists are compared by age. She shared with dev.ua the arguments and criteria by which, in her opinion, it is more effective to evaluate specialists, and also talked about her path to the senior level and gave some advice to specialists who strive to grow, regardless of age.

The terrorist country daily demonstrates its readiness for a ceasefire by increasing the intensity of strikes with "calibers", "shaheeds", "kabs" on Ukrainian cities that are closest to the line of combat contact. Since the beginning of April alone, the Russian army has already used almost 2,800 air bombs, more than 1,400 strike drones, as well as about 60 missiles of various types, including ballistics. dev.ua talked to representatives of the IT community who are in the zone of increased danger about how they react to the next barbaric attacks of the enemy and how they work in constant tension with a target on their backs.

The full-scale invasion was not only a test for Pavel Oleksyn, but also the moment when he made one of the most important decisions in his life — to leave medicine and move to IT. A few years ago, he worked as an anesthesiologist in the neonatal intensive care unit. The transition to a new field was not easy. He had to overcome doubts, find time to study, and adapt to a completely different work environment.

Data analyst from EPAM Andriy Kamuz is originally from Kherson. He lived in the southern city for almost 60 years. He is currently in Odessa, occasionally visits relatives and is waiting for the moment when he can return home. Andriy became an IT worker in 1986, when electronic machines were just starting to appear. The engineer told dev.ua about his journey — from working at a factory to an IT service company, as well as how much he misses his hometown. What follows is his direct speech.

A 32-year-old Ukrainian developer from Uzhhorod, before the full-scale invasion, had been working peacefully for more than 10 years in many companies, creating various software for his customers, and had never thought about a different fate. However, since February 2022, a full-scale invasion has turned his life and work upside down, as it has for many Ukrainians. The man joined the hacker community, but chose the «white» side of the force. The hunter under the nickname «stopwar» told dev.ua about what attracted him to this field, what distinguishes «black» hackers from «white» or «ethical» hackers, and what a specialist can expect in the future.

There’s a huge scandal in the HR-Tech world. Two unicorn competitors are suing over alleged corporate espionage. A story worth billions.

In the past few months, undersea telecom cables have been in the spotlight. In November, an undersea communications cable broke between Finland and Germany. Later, it became known that a similar cable broke between Lithuania and Sweden. In early 2025, Taiwan accused China of damaging an undersea cable that runs to the island nation by its ship. Add to this previous similar incidents in the Red Sea, and today we have a new threat that is shaking up the world order. In this article, we will understand the importance of such, at first glance, "old" technology, whether it is realistic to isolate a country by cutting its submarine cables, and why Elon Musk will not save humanity's communication with his alternative in the form of Starlink.

Imagine 18 teams of IT professionals who worked tirelessly for over a year on something super-large and necessary for almost every Ukrainian. And in the end, such a product was born — a financial superapp that takes into account the most secret desires of over a million users, stands guard over interests and business, and shows an extraordinary dynamics of updates for even greater user comfort. Are you intrigued? We’ll tell you. On February 17, Raiffeisen Bank launched a new multifunctional mobile application, MyRaif, a whole ecosystem of digital finances that adapts to each user, created by the bank’s in-house team. By the end of 2025, both applications will be available to the bank’s clients, but later MyRaif will replace Raiffeisen Online, which the developers will turn off. dev.ua spoke with Viktor Manzar, Head of IT Solutions Implementation at Raifu, about why the need to release a new application arose, what its advantages are, and what features are already available to users today.

In August of last year, the Russians began using modified versions of fiber-optic drones on the front lines. The main reason for the popularity of this type of UAV is the inability to suppress it with the electronic warfare (EW) systems that our front lines are littered with. In addition, there is currently no effective countermeasure against fiber-optics. 3DTech is one of those Ukrainian manufacturers of fiber-optic drones that are working on a response to the occupiers. Last weekend, we visited the testing ground with the company and saw how its improved UAV turned out. We also learned what technological solutions can be effective in the fight against such enemy "birds". More about all this later in the material.

Third, it caused a drop in the stock prices of technology companies, including top graphics processor manufacturer Nvidia. For a detailed analysis of what helped DeepSeek outperform its competitors, read the material.

 Temu online marketplace, whose advertisements have been seen repeatedly on social media and which the EU is already worried about, organizing an investigation against it, has signed a partnership agreement with Ukrposhta. It is reported that as of January 9, more than 1.5 million shipments have already been delivered within the framework of the cooperation. However, Co-founder and Head of the Aurora network Taras Panasenko called such cooperation «shopping without borders, without delays and without any taxes in Ukraine». According to him, the conditions under which foreign marketplaces operate lead to discrimination against Ukrainian manufacturers and retailers.

This week, the IT community celebrated International Programmer’s Day. Ukrainian specialists chose January 7 as their professional holiday so as not to celebrate it together with the Russians. On the occasion of the holiday, dev.ua asked IT professionals what the most unusual requests or assignments they received from their environment, «because you are a programmer.» Here is a selection of the funniest and most non-trivial answers.

«I left IT almost a year ago. There’s no going back. I just put an end to it, because it’s not mine,» says Olga Popova, a graduate of Kyiv Linguistic University, who entered IT right after university, but didn’t stay in the most promising industry for long. To understand that IT is not the area where she would like to develop, the former IT recruiter needed experience working in three companies. dev.ua Olga told why she left the area that many Ukrainians dream of entering, what’s wrong with IT from the inside, and what she does now. Next is the heroine’s direct speech.

«For me, this is a life project,» says Serhiy Tereshchuk, CTO of DVL, in an interview with dev.ua about his new position, planning the company’s further development plans. Recently established after the merger of Datagroup, Volya, and lifecell, DVL is today the largest international telecom group present in Ukraine. It faces many challenges — from ensuring uninterrupted network operation during wartime and booking specialists to developing 5G and launching new products on the market. We met with Serhiy Tereshchuk and talked not only about the above-mentioned topics, but also about the use of artificial intelligence, the situation on the telecom market with small and medium-sized providers, and ambitions in competition with other mobile operators and companies. The interview has been edited and shortened for clarity.

Jimmy Carter, the 39th president of the United States, died on December 29 at the age of 100. He served from 1977 to 1981. Before becoming president, Carter served one term as governor of Georgia. A former naval officer and engineer who later became a peanut farmer, he convinced voters that he had good intentions and would act honestly after the Watergate scandal, in which Republicans spied on Democrats. President Carter had both ups and downs in his biography. One of the details of his tenure is that he ordered the installation of solar panels on the roof of the White House. Why did the president do this, how did it fit into the historical context and where the president's solar panels are now, read on.

Why do employees stay with one employer for 10 or more years? And how do they grow during this period? These questions interest many, because nowadays staying with one employer for such a long time is more of a choice for individuals than a mass trend. dev.ua found such a story. Darya Omelyanenko has gone through a long career path from customer support, through testing and to business analytics in 10 years, and now shares her experience. Next is her straightforward speech.

Anton Protsiuk has been developing the free encyclopedia Wikipedia in Ukraine for more than 12 years. To do this, he has several roles. The first is the head of programs for the public organization Wikimedia Ukraine, which is not part of Wikipedia, but supports its development. For example, he develops Ukrainian education through trainings and programs in which he uses Wikipedia's achievements on a more serious level. The second is a volunteer, editor, and administrator who writes articles for Wikipedia. “When you do this, you learn something new yourself, your materials are read by millions of people, and you help the Ukrainian language and free knowledge develop,” Anton says about his motivation. Further in the article you will learn how (in numbers) the Ukrainian-language Wikipedia feels today, what Ukrainians are currently reading the most among its articles, how unethical organizations that seek to build a business on "free knowledge" work, and how one programmer managed to "raise" the Cebuano language of the Philippines thanks to the "Free Encyclopedia."

The image of Valery Markus, the former sergeant major of the 47th Motorized Rifle Brigade "Magur", in which he appeared in a series of videos explaining his disappearance from the media space in 2023, immediately evoked associations among Ukrainian gamers. A bearded soldier smoking a cigar is not so rare in the gaming industry, and Big Boss from Hideo Kojima's Metal Gear Solid series and Captain John Price from Activision's Call of Duty Modern Warfare immediately come to mind. Although both characters are known for destroying Russian soldiers, Price did so in Ukraine, among other places, so he perhaps resembles Valery Marcus the most, as noted by veteran Oleg Simoroz. We also lean towards the Captain John version, so we decided to not only compare the Price-Marcus visuals, but also find other points of contact between them.
