Выпуск VirtualBox 7.2.12 с устранением проблемы, приводящей к зависанию хостовой системы

Компания Oracle опубликовала корректирующий релиз системы виртуализации VirtualBox 7.2.12, в котором представлено 3 изменения. В дополнениях для хост-окружений с Linux устранена проблема, приводившая к сбою на уровне ядра Linux с переводом ядра в состояние Panic или зависанию системы при запуске виртуальной машины. Зависание проявляется при использовании VirtualBox 7.2.10 у пользователей Debian 13, Arch Linux, Linux Mint, Fedora 44 и других дистрибутивов, в которых при загрузке модуля kvm выставляется опция "enable_virt_at_load=0".

Gemini now generates fully editable multi-slide presentations in Google Slides

Google has updated Slides to allow the Gemini AI engine to generate complete, multi-slide presentations from a single text prompt. Unlike previous iterations that produced static templates, this update creates native layouts where every element, including text and images, remains fully editable by the user. The system includes a planning phase where the AI asks follow-up questions regarding the target audience and tone before generating a reviewable outline.

📰 Some of my smart devices were sneaking around my Pi-hole, and blocking them was easier than I thought

When I implemented Pi-hole on my home network, I thought of it as a set-and-forget thing, as most of the community discussion suggested. I installed Pi-hole on my home Debian server, added a couple of reputable blocklists, and set it as a default DNS on my dual-WAN gateway. And for a while, it really did seem like the job was done. Ads disappeared, obvious trackers filtered out, and the dashboard showed me thousands of blocked queries.

Вышла ZLUDA 6, независимая реализация CUDA

Вышла очередная версия ZLUDA — прослойки совместимости для параллельных вычислений на графических процессорах не-Nvidia, нацеленная на полную совместимость с CUDA. Соответствует версии CUDA 13.1. Пока поддерживаются только AMD (версия ROCm до 7.2), планируется и Intel. Написана на Rust.
Заявлена начальная поддержка работы поверх ZLUDA физического движка PhysX и 3D-редактора Blender.
О названии. Cuda по-польски — «чудеса», złuda — «иллюзия». Автор говорит, что не вкладывал глубокого смысла, просто взял первое попавшееся слово созвучное с CUDA, чтобы сменить название notCUDA.

Firefox is adding Vulkan video decoding for Nvidia GPUs

Firefox is adding hardware-accelerated Vulkan Video decoding, saving Nvidia users on Linux the hassle of manually configuring the nvidia-vaapi-driver package. The change will be included in Firefox 153, out July 21, but it will not be enabled by default – not to start with. Instead, users will be able to flip a pair of preferences in about:config to try it out, with the awareness that there may be hiccups and edge cases (especially on devices with hybrid graphics, mentioned further down). Given that Nvidia GPUs are capable (understatement klaxon), I was surprised to hear that this didn’t already work. Turns out, Firefox’s […]

Rising component costs trigger sharpest decline in US PC shipments since 2023

US PC shipments fell by 7% in the first quarter of 2026, marking the most significant market contraction in nearly three years. This downturn is primarily attributed to severe supply constraints and surging prices for DRAM and NAND flash memory components. Analysts note that the market is also experiencing a demand hangover following the aggressive hardware refresh cycle prompted by the end of Windows 10 support.

Computex 2026 reveals a split market between budget laptops and AI superchips

The laptop market at Computex 2026 has diverged into two distinct tiers focused on affordability and local AI performance. Apple’s MacBook Neo has spurred a wave of competitive budget Windows devices, including the $599 Dell XPS 13 and Acer’s Swift Air 14. These entry-level machines prioritize thin-and-light designs and long battery life but are often limited to 8GB of RAM due to high memory costs.

📰 AMD's new CPU core type just got unlocked on Linux before it was even announced

If you've ever poked around your computer or laptop's power plans, you'll know that your hardware can be fine-tuned to use as much or as little power as you'd like. Normally, you can choose between an emphasis on power and a focus on conserving energy. However, Intel has introduced a third option called the Low Power Efficient cores that saves battery on background tasks and idle states.

Claude Sonnet 5 hidden costs offset performance gains over predecessor

Anthropic has launched Claude Sonnet 5, a mid-tier model designed to deliver performance levels approaching the flagship Opus 4.8. While the model excels at multi-step agentic tasks and coding, independent evaluations show it ranks fifth overall in general intelligence benchmarks. It introduces an "adaptive thinking" mode by default, which allows the model to handle complex automation workflows that previously required more expensive tiers.

VirtualBox 7.2.12 resolves host kernel panics and improves Windows DX11 performance

Oracle has released VirtualBox 7.2.12, a maintenance update addressing a critical stability flaw affecting Linux hosts. The most significant fix resolves a bug that caused full kernel freezes on Arch Linux when attempting to start a virtual machine. This issue previously required a hard hardware reset because the system would stop responding before any diagnostic information could be logged.
