Useful Guidelines

Ukrainian defense-tech has moved into mass production, but the enemy is also adapting, taking technological warfare to a new level. To create advanced complexes, Ukrainian developers no longer have the right to design at random. Basic 3D models do not show how the product will behave in conditions of severe vibrations or extreme overheating, which leads to the loss of equipment and lives. Trying to fix it at the test site is a waste of months and wasted investments. Let’s talk about four hidden physical problems that are killing drones and ground robots.

How text-based social networks are changing and why the old rules of the game no longer work

The main demand from entrepreneurs is shifting towards simplicity and automation. According to the global Mastercard Dreamonomics study, small and medium-sized enterprises already use an average of five digital business tools, 89% want to use them even more, and 78% consider the integration of such services with each other to be critical.

I was recently collecting fresh data for my Coupler.io team on how people are using Claude for analytics. It would seem that it is difficult to surprise us: we build a data platform with AI analytics ourselves, monitor the market and have a good understanding of where it is going. And yet, a few numbers surprised me. Not the direction of change, but its speed. Two years ago, we were just starting to explain to our audience that conversational analytics requires both data and processes. Today, 70% of Claude users have it set up as their only data tool. That is, for seven out of ten, it is no longer an addition to their usual BI or a way to test a hypothesis from time to time. It is the main place where they ask questions of their data. If you work with data, are responsible for analytical processes in a team, or are simply watching how AI enters business, I suggest you analyze together what exactly is changing in people's behavior around data and what this means for business analytics in the next six months.

When a service runs 24/7 and has external and internal consumers, there is virtually no window for maintenance. This is the task that the SharksCode team faced when migrating a high-load backend component along with its data layer to a new infrastructure and a new data storage scheme. The old implementation began to limit scalability and make it difficult to scale the read and write load independently. Meanwhile, any schema changes and releases were becoming increasingly risky. The company was preparing the system for further growth and wanted to do it without a single minute of downtime.

In 1994, the AT&T banner appeared on the HotWired website, making it the first web banner ad. It was clicked on by 44% of those who saw it—nearly one in two, recalled the ad’s co-author Joe McCambly. By today’s standards, this is an exceptional result. For comparison: in a July 2025 article , Semrush notes that the click-through rate for display advertising often falls below 1%—less than one click per hundred impressions. But already in 1997, three years after the launch of the AT&T banner, researchers at the Nielsen Norman Group described banner blindness — the tendency for users to ignore elements on a page that look like advertisements.

Hello! My name is Oleksandr Nigmatulin, I am the co-founder and marketing director of PRNEWS. Working with media publications, I regularly see listicles — from truly useful lists to random ones, compiled without clear criteria and sufficient context. In this article, I’ll walk you through how to create listicles that help readers compare options, capture related search queries, and can be visible in AI search. I’ll also explain where useful format ends and clickbait begins.

A team of 40 engineers can be a large project for a customer and one of dozens of accounts for a global IT vendor. When something goes wrong, the difference becomes noticeable: the response goes through several levels of approval, the search for the right specialist is delayed, and the person capable of making the decision has almost no contact with the customer.

SEO has long ceased to be about buying links on exchanges and adding keywords to the text like «buy a laptop in Kiev cheaply.» Now it’s not just not working — for this, Google’s algorithms give sites an instant one-way ticket to the end of the search results.

A task that used to take a week now takes two days. But that’s not the most interesting thing. I didn’t buy Zapier, Make, n8n or any other automation platform for this. Over five months, I gradually connected the services I use every day via API and wrote small scripts for them. They run locally on my Mac, and Claude Code runs them in the right order.

Ukrainian IT professional Serhiy Bezbabnykh developed the Lost and Found app, which aims to return lost items to their owners.

Ukrainian developer Andriy Kovalchuk launched the Zerva marketplace, which, according to his plans, should connect customers, contractors, and construction companies on the topic of Ukraine’s recovery.
