The robot shows the person a recognized captcha, and the site owner holds his head in concern. — Captcha no longer stops AI

CAPTCHA has long been considered one of the simplest and most reliable ways to protect websites from bots. It required the user to perform an action that automated programs supposedly could not repeat: recognize distorted characters, select images with bicycles, or mark all traffic lights. But the era of artificial intelligence has changed the rules of the game. What seemed impossible for a computer ten years ago is now performed by algorithms faster and more accurately than humans. Website owners are now facing a reality where the familiar CAPTCHA no longer guarantees protection.

Why Governments Started Investing Trillions in AI Infrastructure

A group of people in business attire are discussing a large AI processor against the backdrop of data centers and a government building with a dome. — The state as a key investor in strategic AI infrastructure

Artificial intelligence has ceased to be a laboratory experiment and has become the foundation of a new economy. If just a few years ago AI investments were associated mostly with private companies, today governments have actively joined the race. The USA, the EU, China, Japan, and the United Arab Emirates are competing to build the most powerful data centers, purchase thousands of GPUs, develop their own models, and even form state-level alliances with corporations. The amount of investment is no longer counted in billions — but in trillions of dollars.

How 1U Servers Differ from Mini PCs That Are Also Mounted in Racks

A person is debating between choosing a 1U server and a mini PC, pictured on either side. — Finding a balance between power, format and ease of placement

In today’s world, compactness is not just a convenience — it’s a necessity. Companies strive to fit more computing power into smaller spaces, while technical specialists look for ways to optimize performance without sacrificing efficiency. That’s why, alongside traditional rack-mounted server solutions, mini PCs are increasingly appearing — and at first glance, they might seem like a decent alternative. However, there is a significant difference between them — both in purpose and in capability.

How Smart Plugs Help Manage Energy Consumption During Power Outages

The smartphone controls the heater via a smart socket with a Wi-Fi module. — Convenient power management during power outages

At a time when electricity supply is often unstable and energy saving has become a matter not just of economy but also of protecting household appliances, smart plugs come to the rescue. These small devices can turn an ordinary electrical appliance into part of a smart home, allowing users to remotely control power, monitor energy consumption, and even automate device operation. But how exactly do they help during outages, and why have they become so popular in recent years?

How Data Centers Isolate Vibrations from Server Racks

The server rack is mounted on a platform with springs that isolate vibrations. — Protecting servers from vibrations and micromovements

Modern data centers are not just rooms filled with servers. They are complex engineering systems where every detail matters — from air temperature and humidity to the slightest floor vibrations. One of the least noticeable yet critically important factors for stable server performance is vibration. It can cause microscopic failures in hard drives, accelerate component wear, and, under heavy load, even lead to hardware failure. That’s why engineers pay great attention to isolating vibrations inside data centers.

Replacement of disks and power supplies without shutting down the server

An engineer installs or replaces a server module in a data center rack. — Hot swapping allows servers to be serviced without interruption

In a world where business processes operate continuously and online services are available to users 24/7, the stability of servers becomes one of the key success factors. A website may receive thousands of visitors per day, a CRM system serves managers in real time, and financial transactions take place every second. Under such conditions, even a short downtime can have significant consequences: from halted sales and disrupted internal processes to loss of reputation and customer trust. That is why modern servers are designed to remain operational even during maintenance. One of the technologies enabling this is the ability to hot-swap disks and power supplies.

AI Accelerators as the Foundation of Modern Data Center Architecture

AI accelerators are becoming the core of modern server infrastructure

The rapid progress of artificial intelligence has forced the data center industry to radically restructure: classical server farms must transform into AI-oriented “supercenters” with supercomputer-level power and new infrastructure requirements. At the core of these changes are specialized AI accelerators — hardware chips designed to speed up machine learning tasks, which have essentially become the foundation of modern data center architecture. Without such accelerators, breakthroughs like ChatGPT would take much more time and money — no wonder AI accelerators are now widely used by global tech giants.

How a Hypervisor Divides a Physical Server into VPS

The physical server is divided into several independent VPSs. — Partitioning hardware resources into separate virtual environments

Not so long ago, to launch a website or an online service, it was necessary to rent or purchase a whole physical server. This is expensive, difficult to administer, and comes with excessive capacity that often remains unused. The situation changed with the appearance of virtualization — a technology that allows creating several independent virtual servers on a single physical server. Each of them operates as if it has its own processor, memory, disk space, and operating system. The key element of this process is the hypervisor. It acts as a “conductor” that controls the distribution of resources and ensures the stable operation of each VPS.

Why Free SSL Certificates Are Not Always Suitable for Business

A man in a suit looks thoughtfully at an image of an SSL certificate marked "FREE." — Which SSL certificate should you choose for your business?

When we talk about website security, the first thing that comes to mind is the SSL certificate. It encrypts the data transmitted between the browser and the server, protecting it from interception. A site with the padlock icon in the address bar appears more trustworthy, which is why many companies use free SSL from Let’s Encrypt and similar providers. However, the question is whether this solution is always suitable for business. In reality, free SSL is a good starting point, but it doesn’t always offer the level of trust, control, and stability required for commercially valuable websites.

Why laptops are becoming fanless and what it means for performance

Laptop on a table with a crossed out fan icon and question marks around it. — Why modern laptops are abandoning coolers and how this affects heating and speed

Not so long ago, fanless laptops seemed like niche devices: they were bought only by those who valued absolute silence rather than speed. It was believed that passive cooling could not cope with the heat generated by the processor, which meant that the performance of such laptops would be low. However, in recent years the situation has changed dramatically. The market has seen models that combine silence, compactness, and enough power for everyday tasks. This is not just a trend, but the result of significant changes in the approach to hardware design and processor architectures.
