OpenArc: A Lightweight Inference API for Accelerating LLMs on Intel Hardware

OpenArc is a lightweight inference API backend leveraging the OpenVINO runtime and OpenCL drivers to accelerate inference of Transformers models on Intel CPUs, GPUs, and NPUs. Designed for agentic use cases, it features a strongly-typed FastAPI implementation with endpoints for model loading, unloading, text generation, and status queries. OpenArc simplifies decoupling machine learning code from application logic, offering a workflow similar to Ollama, LM-Studio, and OpenRouter. It supports custom models and roles, with planned extensions including an OpenAI proxy, vision model support, and more.

Remote Radioactive Material Detection: A 10-Meter Breakthrough

Remote Radioactive Material Detection: A 10-Meter Breakthrough

Researchers at the University of Maryland have developed a novel method for remotely detecting radioactive materials using short-pulse CO2 lasers, achieving detection at a distance of 10 meters—over ten times farther than previous methods. The technique leverages the ionization of surrounding air by radioactive materials. By accelerating these ions with a laser, a cascade of ionization creates microplasmas that scatter laser light, enabling remote detection. This technology holds promise for nuclear disaster response and nuclear security, but challenges remain, including the size of the laser system and environmental noise.

Supreme Court Upholds TikTok Ban: National Security Trumps Free Speech

The Supreme Court unanimously upheld a federal law banning TikTok unless its Chinese parent company sells it. The ruling prioritizes national security concerns over free speech arguments, citing risks posed by TikTok's ties to China. While President-elect Trump suggested a negotiated solution and the Biden administration indicated it wouldn't enforce the ban immediately, the decision leaves TikTok's future in the US uncertain. The court found the law did not violate petitioners' First Amendment rights.

Using eSIMs on Devices with Only Physical SIM Slots: A 9eSIM Review

This blog post details using a 9eSIM SIM card to enable eSIM functionality on devices that only accept physical SIM cards, tested on Android and Linux. The author purchased a 9eSIM bundle including the SIM, smartcard reader, and adapter. Initial setup proved slightly tricky, requiring the SIM card to be used within its original packaging for proper reader connection. Adding, switching, and deleting eSIM profiles was straightforward using an Android app or the Linux command-line tool lpac (and its GUI, EasyLPAC). Tests were conducted with free test eSIM profiles and a paid LycaMobile eSIM, successfully achieving eSIM connectivity on a Debian Linux laptop.

The Event Horizon Telescope (EHT) Collaboration has released a new analysis of the supermassive black hole at the center of Messier 87 (M87*), combining observations from 2017 and 2018. The study confirms that M87*'s black hole rotational axis points away from Earth and highlights the significant role of turbulence within the accretion disk in explaining the observed shift in the ring's brightness peak. Using a vastly expanded simulation image library, the team confirmed the counter-clockwise 30-degree shift of the brightest region of the ring between 2017 and 2018. This research represents a major step forward in understanding the complex dynamics of black hole environments.

IPv6 Isn't Hard, It's Just Different: A GitHub Case Study

A Mastodon post lamented the difficulty of IPv6 configuration. The author uses GitHub as an example to show that the problem isn't IPv6 itself, but inadequate configuration and monitoring. Many websites, while having IPv6 address records (AAAA), are actually inaccessible via IPv6 because the browser's Happy Eyeballs mechanism prioritizes faster IPv4. In one case, a customer's split VPN tunnel blocked IPv6 connections. In another, traceroute showed that IPv6 routing terminated earlier than IPv4, indicating a possible firewall rule or routing issue. The author concludes: take IPv6 seriously, or don't use it. Lack of IPv6 monitoring and automation makes problems difficult to detect and resolve.
