For some time, I have been actively working on Instafill.ai technology, the main task of which is to relieve lawyers and ordinary users from the routine of filling out PDF forms.

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.

Hello! It’s #vsrativakansii again. And again, there are a few crony offers and HR stories that are being hotly discussed by IT people.

A few years ago, the profession of a producer was associated with show business, celebrities, and big money. Today, this is a person who explains to a senior with 10 years of experience that recording a video about bugs is more important than the bugs themselves. And rehearsing a webinar is more serious than a code review. If this seems like a simple task to you, try persuading an IT guy to re-record a lesson because of one mispronounced word. IT education has already turned into a separate industry, in which the producer plays one of the key roles. Darya Bilokon, Producer Team Lead of the Laba and robot_dreams online schools, told dev.ua about the profession and its features in the section on IT professions.

OpenAI has trained its GPT-4o model to generate images and has made it available to paid subscribers.

Here’s what intellectual property experts have to say about it.

My name is Vlad Chukhrai, and before becoming a project manager at the fintech company bill_line, I held a position in business support. In the case of payment service providers, support does not solve problems with payments of specific customers — this is done by the merchant we work with. The support team that handles processing looks at a more strategic level: how to solve a specific merchant problem in the context of the full transaction processing cycle and how to avoid illegal actions with people’s money. Today I would like to talk about my own experience based on cases and rules that the company has.

22-year-old Bohdan Oliynyk has been working as a DevOps Engineer for 8 months, has already worked on more than one project and has brought many solutions, having a Strong Junior level closer to Middle. However, he recalls that he never thought that he would choose this specialty, and he managed to get into IT only on the fourth attempt. Twice he started learning Front-end, twice — Python, at some point he even had the thought that this field was not for him. But the young man did not give up his attempts and in the end they were crowned with success. He told dev.ua about all the ups and downs and shared life hacks that can help other beginners find themselves in the technosphere.

A powerful historical update of ChatGPT has taken place. Now the chatbot can be used to generate images and process existing visuals and photos.

But the situation is changing.

OpenAI CEO Sam Altman has unveiled a major update to ChatGPT’s image generation capabilities. Now, the AI ​​chatbot can use OpenAI’s GPT-4o model to create and modify images and photos. What are the advantages and disadvantages of image generation in GPT-4o?

Many professionals have already realized that IT is not only about code, startups and remote work from anywhere in the world. It is also about money. Big money.

The trend of vibe coding, where programmers simply ask AI to perform certain tasks and do not delve into the actual code offered by the chatbot, is gaining momentum, and IT professionals have different (sometimes negative) opinions about this practice. However, a number of representatives of prominent tech companies believe that vibe coding can increase programmer efficiency. Here’s what they advise.

A major leak of information related to the Donald Trump administration has occurred in the US. An American journalist accidentally found himself in a Signal chat room where top officials were discussing an attack on military targets in Yemen. Why are such stories happening more and more often? And how does high-level communication take place in Ukraine?
