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.

LFortran Compiles PRIMA: A Major Milestone Towards Beta

2025-03-09

The LFortran compiler team successfully compiled and executed libprima/PRIMA, marking the eighth production-grade, third-party code compiled with bit-for-bit alignment to GFortran. This significant milestone brings LFortran closer to its goal of compiling ten such codes, a key step toward achieving beta-quality. Compiling PRIMA, a Fortran package for nonlinear optimization, presented challenges related to procedure variables, arrays with non-unit strides, and precision loss, all of which were overcome. Future efforts focus on compiling additional third-party codes, including fpm and LAPACK, to solidify LFortran's beta readiness.

GPL: Boon or Bane for WordPress?

Daniel Jalkut of Red Sweater Software argues that the GPL license hinders participation and adoption in WordPress. This article counters that argument, asserting that WordPress's thriving plugin and theme community is a direct result of the GPL. The author uses personal experience to show how the GPL protects user freedoms and ultimately fosters a flourishing ecosystem rather than hindering development. While acknowledging limitations, the core principles of sharing and reciprocity are vital for building a robust community and ecosystem – far outweighing license concerns.

Basel Tax Authority Buys Bahamian Web Address Due to Flyer Error

The Basel-Stadt tax authority had to purchase a web address in the Bahamas due to a mistake on an information flyer for digital tax returns. The flyer, sent to over 100,000 households, omitted the '.ch' from the web address, redirecting users to a '.bs' domain in the Bahamas. While the error has been addressed and the Bahamian address will redirect to the correct Swiss site, the mistake cost the authority CHF 900, significantly cheaper than the estimated CHF 100,000 to reprint the flyers. Taxpayers can still file their returns online, albeit with a brief Caribbean detour.

Trump Admin Ends Paper Checks, Goes All-Digital

President Trump's executive order, effective September 30th, eliminates paper checks for all US Treasury disbursements. This includes tax refunds, vendor payments, benefits, and intergovernmental transfers. The move aims to combat waste, fraud, and abuse, citing that paper checks are 16 times more likely to be lost, stolen, or altered than electronic transfers. Maintaining the paper check system cost $657 million in 2024. While check usage declines, fraud is rising, prompting the American Bankers Association to applaud the change and encourage digital banking. Exceptions will be made for those lacking banking access, emergencies, law enforcement, and other specified cases.

X Platform Bans Signal.me Links: A Blow to Privacy?

Elon Musk's X platform (formerly Twitter) has recently banned links to Signal's "Signal.me" URL, preventing users from posting them in DMs, public posts, or even their profile bios. This move raises concerns, as Signal, with its end-to-end encryption and privacy focus, is a crucial communication tool for journalists and whistleblowers, particularly relevant amidst recent US government data leak controversies. While users can still share their Signal usernames manually, this added friction impacts communication and potentially threatens information security and press freedom. The ban signals a further tightening of information control on X, with the motivations remaining unclear.

Xiaomi's Draconian Bootloader Unlock Policy Sparks Debate

Xiaomi has drastically tightened its bootloader unlock policy, limiting users to unlocking only one device per year. While this change minimally impacts average consumers, it could significantly hinder custom ROM development. This move has sparked a debate about device ownership and user freedom, with speculation focusing on Xiaomi's motivations, including preventing users from bypassing built-in ads and tracking, or thwarting scalpers reselling phones with modified software. Users see this as restricting choice, while developers worry about reduced efficiency in custom ROM creation.
