Hackers compromised internet-connected Danfoss refrigeration controllers in supermarkets across Europe, forcing the units into automatic defrost mode that raised temperatures to around 50°C and disrupted food storage, deliveries and pricing. The attack exposes critical OT/IoT security weaknesses in legacy refrigeration hardware, threatening food safety and supply‑chain stability across Europe and prompting urgent calls for better segmentation and patching of industrial control systems. Researchers linked the incident to vulnerabilities in Danfoss AK‑SM 800A and older models such as the SM800 (EOS 2021) and SC355 (EOS 2016), with CVEs allowing remote activation of defrost cycles; affected supermarkets reported losses of up to €270,000 per store and potential continent‑wide damages in the millions.

An open-source project replaced the MediaTek MT7996 firmware in a Gemtek W1700K Wi-Fi 7 router with custom firmware, enabling the radio to capture 14-bit IQ samples at up to 320 Msps across the 2.4/5/6 GHz bands and stream them over 10 GbE via zero-copy UDP. This shows that low-cost consumer Wi-Fi 7 hardware can be repurposed for high-speed software-defined radio, lowering the entry barrier for wideband RF experimentation and enabling affordable spectrum monitoring, research, and hobbyist use. The custom firmware reverse-engineers the radio registers to output 14-bit IQ data, which a Linux host processes to render a live spectrum; the router’s 10 GbE interface uses zero-copy UDP for low-latency streaming. Commenters note that the same MT7996 chipset is present on boards like the Banana Pi R4, which offers a PCIe NVMe slot for additional storage or expansion.

Starting with version 0.157.0, the OpenAI Codex CLI automatically launches a persistent background daemon (app‑server --managed‑daemon) that survives session closure, copies a ~374 MB platform package into a versioned directory, and runs an hourly updater. This default behavior consumes significant disk space, can corrupt file permissions, and removes user control over background processes, affecting developers who rely on the CLI for reliable, lightweight coding assistance. Users can disable the daemon by setting daemon_auto_start = false in ~/.codex/config.toml, and mitigate leftover files by deleting pid/lock files, symlinking them to /dev/null, and marking them immutable with chattr +i.

The article examines the obscure x86 instruction VFMADDRND231PD, detailing its origin as an AVX-512 FMA variant with rounding control, why it was removed from Intel's architecture, and why it never functioned as intended. Understanding why such an instruction was dropped highlights hardware design pitfalls and helps compiler developers avoid relying on undocumented or buggy extensions, while also illustrating the evolution of x86 SIMD capabilities. VFMADDRND231PD was defined as a fused multiply‑add of packed double‑precision floating‑point values with explicit rounding control, but silicon never implemented it correctly, leading to its removal from later ISA revisions.

A guide posted on lunarwatcher's Codeberg page describes a manual method to make large file downloads resumable in Firefox by managing .part files and adjusting the network.http.response.timeout setting. This technique helps users with unstable connections avoid restarting large downloads from scratch, saving time and bandwidth without relying on third‑party download managers. The process involves moving the existing .part file to a temporary location, restarting the download to create a new .part, pausing, swapping the temp file back, then unpausing to resume from the previous offset; it only works for one‑time links and requires manual file manipulation.

The article provides a step‑by‑step tutorial on writing a demoscene intro for the ZX Spectrum, covering the programming tricks and hardware constraints involved.

The author employed the newly released GPT-6 Astra language model to generate prompts that, after jailbreaking a Kindle, were displayed on its e‑ink screen, effectively turning the device into an AI‑powered photo frame. This demonstrates how advanced LLMs can be leveraged for hardware repurposing and highlights both the creative potential and security implications of jailbreaking consumer e‑ink devices. The jailbreak followed known Kindle modding techniques, while GPT-6 Astra (released September 4 2026) supplied AI‑generated images that were refreshed on the Kindle’s low‑power e‑ink display; however, the model’s existence is currently speculative and the modification may void the device’s warranty.

The Janas project, hosted at github.com/prabanta-dev/janas, introduces a system that streams Mixture‑of‑Experts (MoE) expert layers from an SSD during inference, allowing LLMs larger than the host’s RAM to run. By offloading inactive experts to storage, Janas reduces the memory footprint needed for large MoE models, making it feasible to run state‑of‑the‑art LLMs on memory‑constrained edge devices or consumer PCs. Janas loads only the expert sub‑networks activated for each token, using memory‑mapped SSD reads; performance is therefore bounded by SSD bandwidth and latency, and the approach builds on earlier work such as FlexGen and llama.cpp’s mmap‑based offloading.
