A WONDERFUL FUTURE

Technology is advancing at an astonishing rate. It seems like only yesterday that domestically produced KR1810VM86M microprocessors with a clock rate of just 8 megahertz appeared, forever dividing our lives into “before” and “after.” And a set of eight K565RU7 memory chips (similar to the Intel 41256) provided a RAM capacity of 256 kilobytes, a fantastic value for its time.

Back then, it seemed that with such rapid development, humanity was about to transcend the galaxy and rush to other worlds. Today, these figures only evoke a smile, but it was precisely with such advances in computing technology in the 1980s and 1990s that our journey into the future world of ones and zeros began.

The Missing Road Signs That Will Get Driverless Cars Out of Traffic Jams

Level of difficultyEasy
Reading time6 min
Reach and readers3.2K

Operating autonomous vehicles in mixed traffic with human-driven vehicles imposes two fundamental limitations. First, sharing roads with conventional vehicles causes delays through traffic congestion. Second, unpredictable behaviour of human drivers and pedestrians, together with current traffic regulations, prevents autonomous vehicles from realising the full benefits of automated vehicle-to-vehicle coordination – optimal distance control, prioritised merging, dynamic road load management, and automatic compliance with radio-transmitted vehicle-to-infrastructure (V2I) commands.

To overcome these limitations, physically segregated road sections or physically segregated lanes must be introduced, reserved exclusively for highly automated vehicles operating in fully automated mode without a driver on board. These segregated sections and lanes require special traffic management rules, including dedicated road signs, road markings, entry and exit procedures, and V2I commands.

Physically segregated lanes and road sections would allow the safe exploitation of all capabilities of fully automated mode, including centralised control via V2I commands as technical readiness permits. To implement such segregation, new road signs are needed that clearly mark the boundaries of these sections and inform all road users of the applicable rules.

This article is for the IT specialists working in regional road authorities. Since your recommendations influence the development of transport infrastructure, let us discuss what is happening on our roads in the field of high technology!

This topic has become a real headache. Whenever a region allocates funds for an ITS (Intelligent Transport System), everyone wants to install smart solutions at the busiest intersections in the city center. SpesLab constantly receives requests about this, and we are already tired of explaining that it is a bad idea.

Xeovo donates to Tor x Funding The Commons

Reach and readers3.3K

Xeovo contributed to the Tor × Funding the Commons matching pool, supporting projects that build tools for privacy, anti-censorship and journalists.

We are a relatively small VPN provider, but we believe companies working in privacy should give back to the projects/tools that keep the internet open.

Internet freedom has declined for 15 consecutive years. This is not only happening in authoritarian states. Even democratic countries are introducing more surveillance powers, censorship mechanisms, age-verification systems, weakening encryption and laws that can make private communication impossible.

At the same time, censorship and surveillance tools are becoming more sophisticated, while public understanding of digital privacy continues to decline.

We hope our contribution of $10,000 can make a small difference and help these projects continue their work. If you are interested, we encourage you to check out the Tor × Funding the Commons campaign. And if you are able to donate, even a small contribution can help support the tools that keep the internet open.

Xeovo supports other privacy and anti-censorship projects as well. In the future, we plan to publish a public page showing the initiatives we have contributed to.

Security Week 2626: вредоносные обои рабочего стола в Steam Workshop

Reading time4 min
Reach and readers4.3K

На прошлой неделе исследователи «Лаборатории Касперского» опубликовали разбор свежей кампании по распространению вредоносного ПО в Steam Workshop, встроенной в игровую платформу Steam мастерской для обмена пользовательским контентом. Для заражения пользователей злоумышленники используют программу Wallpaper Engine — это платная утилита для создания кастомных обоев рабочего стола. Возможности программы достаточно широки — от анимации и воспроизведения видео до запуска приложений. Именно этой особенностью и воспользовались организаторы атаки.

Исследователи наблюдали два варианта распространения вредоносного ПО под видом анимированных обоев. В самом простом варианте жертве доставлялся архив, внутри которого содержались и обещанные обои, и вредоносные файлы. Чуть более сложный метод предполагал распространение в уже запароленном архиве. К нему был приложен скрипт, который распаковывал архив и запускал вредоносную нагрузку автоматически. Обои публиковались в Steam Workshop с конца 2025 года. Авторы отчета обнаружили десятки вредоносных обоев, причем некоторые из них имели десятки тысяч скачиваний. Результат установки такого ПО ожидаемый: кража учетной записи Steam, установка вымогателя-шифровальщика и запуск криптомайнера.

Mentorpiece Vacy Index June 2026: Classic Tech Role Hiring Drops, While Dedicated AI Remains Niche

Unfortunately, the Tech Hiring Activity Index for June doesn’t bring any particularly good news.

However, there is a compelling trend: just two months ago, roughly three times as many US tech companies were hiring for classic manual QA as for dedicated AI testing roles. That gap has now narrowed to two to one.
But don’t let the growth rates fool you. While dedicated AI roles – those where AI is the deliverable, whether that means building, testing, and evaluating models or developing applications on top of ready-made ones, rather than merely using AI tools to support other work – are emerging, they are doing so from a very low baseline and still represent a tiny fraction of the overall tech job market.

Every day, every single day, devices in fire suppression systems need to be checked! When these are enormous warehouses spread across vast territories, a security guard has to constantly walk around and inspect all of them — just for this one task. The pressure gauge has become a symbol of punishment in fire safety authorities.

Millions of analog sensors are also used in gas and water distribution systems, as well as in many other industries.

The gradient that changed after publishing: reading color from 16-bit screenshots on iOS

Level of difficultyMedium

Some users reported that the gradient behind a picture in a story looked one way before publishing and a different way after — but only for screenshots. The culprit: iPhone screenshots are 16 bits per channel, while our color extraction only understood 8. Here’s the debugging story and the fix — byte order, component layout, and turning two adjacent bytes back into one 16-bit value.

Even among the dots and dashes, you can recognize the hand of a radio operator. And by the style of typing on a computer keyboard, it has become possible to determine the author of the text with almost 100% accuracy.

As a result, we get another sign of identification and authorization.

UUIDv7 and RFC 9562 FAQ

Level of difficultyMedium
Reading time3 min

I am a contributor to RFC 9562, and I wrote this FAQ because I kept seeing the same concerns about UUIDv7 surfacing across Hacker News, Reddit, and developer blogs. The discussion would always circle back to the same objections, most of which are superficial and fall apart when you look closer. UUIDv7 is too big. The timestamp leaks creation time. It creates hot shards. It’s slower than BIGINT. Sorting breaks if clocks drift. After encountering these objections repeatedly, I decided to collect the most debated questions in one place and answer them based on real implementation experience.

Two Generals, One Temptation: The Quantum ACK Challenge

Level of difficultyMedium
Reading time9 min
Reach and readers7.3K

What if the “spooky” correlations of quantum entanglement could confirm receipt of a one-way message, ending the acknowledgment (ACK) regress in the Two Generals’ Problem, without sending anything back? This Opinion explains, in everyday terms, why standard quantum mechanics forbids that hope and offers a clear yardstick for testing claims: the quantum trigger, a hypothetical local device that would behave like an ACK if it existed. We show why such a device has zero advantage under the no-signaling rule, unpack how ordinary timing, spectral and physical-emission leakage, shared schedulers, and post-selection can impersonate a “quantum ACK,” and provide quick diagnostics any team can run.

Mini Bucket 3.6.4: Now with plugins — the door is open for developers

How we turned a NAS control panel into an extension platform, why Log Manager was needed, and what the Plugin Template is for.

In the previous article (Mini Bucket 3.6.2: from beta to release), I showed how the panel matured to a stable state: we patched holes, separated databases, and added HTTPS.

But it’s still just a panel. SMB, FTP, and the rest are standard features found in almost any admin panel. It’s time to expand the functionality.

The best solution turned out to be: .....
