Xeovo donates to Tor x Funding The Commons

Reading time1 min
Reach and readers4K

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 readers5.1K

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

Level of difficultyEasy

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
Reach and readers6K

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 readers7.6K

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: .....

Author: Sergey Lukyanchikov, C-NLTX/Open-Source

Disclaimer: The views expressed in this document reflect the author's subjective perspective on the current and potential capabilities of jBPM.

TL;DR: Zero "quantum supremacy". Zero "agentic orchestration". Zero other hype. Just an approach to achieving an efficient quantum-assisted automation using 100% free open-source components (except for Azure).

In my previous article, I discussed the rationale for adopting jBPM as an AI orchestration platform. This article extends that discussion by examining jBPM’s ability to automate quantum computations and to incorporate their results into business processes and related analytical workflows:

About a year ago, I decided to create a universal open-source solution for list visualization. In the first versions, I tested the virtualization technology with various parameters, and there was a lot of research and questions. Today, version X.12.X was released, which runs on Angular 14-22. I’d like to talk about the capabilities of the tool (ng-virtual-list), the problems it solves, and give a brief overview with examples.

All examples below are contained in the code sample documentation.

The ng-virtual-list tool provides virtualized, high-performance lists with a variety of features that standard lists don’t have.

A native macOS load tester app — and backpressure made it honest

Level of difficultyEasy

Why I built Requester, a real-time HTTP load testing app for macOS, and what Swift structured concurrency taught me about telling the truth under load.

I wanted to hammer an HTTP endpoint and see what happened. Not read a summary report three minutes later — watch it, live, the way you watch a profiler.

The existing options are great but they all live in the terminal: wrkheyk6. I love them, but I kept wishing for a native window with a chart that moved. So I built one for macOS, in Swift and SwiftUI, and called it Requester.

This post is less “here are the features” and more “here are the three things I made building it.” The most interesting one: making the tool honest about backpressure turned out to be a design decision, not an accident.

Why Debian 9, PHP 7.0, and no frameworks. And how to set up HTTPS in 5 minutes.

Foreword for those who haven't read the first article

Last time, I told the story of how I wanted to make a couple of pages for SAMBA and NFS, but ended up with a NAS control panel of 20+ pages. I named the project Mini Bucket.

Important: That version was a beta. Raw, with rough edges, but alive. Its goal was to demonstrate the concept. And people got interested. So, it needs to be polished.

Now – version 3.6.2. A ton of problems have been fixed, security has been added, a separate domain, forum, and wiki have appeared. Today, I'll walk you through the installation step-by-step with screenshots.

But first – a quick summary of what has changed. Then – pure practice.

AI Workspace System: one local workspace for Codex, Claude Code, and GitHub

Level of difficultyMedium
Reading time6 min
Reach and readers9.1K

I ran into a very practical problem after doing a lot of local work with AI agents. I had Codex projects, Claude Code projects, regular repositories edited with agents, drafts, pipelines, instructions, skills, artifacts, and several machines. At some point it became hard to tell where the current version of a project lived, which files were safe to push, where agent instructions belonged, and where source code had already been mixed with logs and intermediate output.

That is why I built AI Workspace System: a small set of shell scripts, conventions, and Markdown documentation that makes local AI-agent work predictable. It is not an IDE and not an agent orchestrator. It is a thin infrastructure layer around Git, GitHub, Codex, and Claude Code.

The core idea is simple: all projects should be visible from one list, instructions should follow one structure, sync should be safe by default, and machine-specific details should not live in the repository.

Ekahau Sidekick and RSSI Offset: Physical Limits of the Method and Why Real Client Behaviour Cannot Be Fully Modelled

Level of difficultyMedium
Reading time13 min
Reach and readers6.9K

Abstract. This work examines the physical foundations of Ekahau Sidekick measurements and the device offset mechanism from the perspectives of antenna theory, receiver noise theory, statistical signal theory, and the IEEE 802.11 standard family. It is shown that the scalar received signal strength indicator (RSSI) offset constitutes a linear level shift and does not model the true signal-to-noise ratio (SNR) of the client device, the quadrature amplitude modulation (QAM) constellation structure, the rate adaptation algorithm, or roaming behaviour. In addition to five independent physical and systemic sources of inaccuracy, the paper addresses modeling assumptions in Ekahau with respect to multiple-input multiple-output (MIMO) gain, multipath propagation, airtime estimation, and SNR visualisation. Verified numerical error estimates for representative deployment scenarios and practical recommendations are provided.
