Pi Pico Rx: A Minimalist Software Defined Radio

2025-03-26

This article details the Pi Pico Rx, a remarkably simple software-defined radio (SDR) receiver built around a Raspberry Pi Pico. Using only a few components – a Pico, an analog switch, and an op-amp – it covers LW, MW, and SW bands, receiving signals from across the globe. The Pi Pico Rx cleverly utilizes the RP2040's PIO feature for quadrature oscillator generation and employs unique IQ sampling and DSP algorithms to demodulate AM, FM, SSB, and CW. Further features include an OLED display, spectrum scope, 512 programmable memory channels, headphone/speaker output, making it a functional and accessible DIY project.

Who Wants Impartial News? A Cross-National Study Reveals the Complexities of Preference

Who Wants Impartial News? A Cross-National Study Reveals the Complexities of Preference

A new study investigates preferences for impartial news across 40 countries. While most people express a preference for impartiality, certain groups lean towards news aligning with their views: politically engaged individuals with strong ideologies, young people relying heavily on social media, women, and those with lower socioeconomic status. The study also finds higher support for non-impartial news in countries with diverse news sources and lower-quality democracies. This challenges traditional notions of journalistic impartiality, suggesting that perceptions of 'impartiality' are deeply contextual, shaped by political, social, and economic environments.

Browser Font Size Preferences: Debunking the 16px == 1em Myth

This article explores the limitations of browser font size preferences and how to better achieve responsive typography. The author points out that the browser's default font size isn't always 16px, and simple pixel calculations based on em and rem units don't adapt to all user preferences. The article suggests abandoning pixel-based font size calculations, using the browser's default font size directly, and using the `clamp()` function with viewport units for responsive adjustments to provide the best reading experience on different screen sizes. A custom element-based solution is also proposed, allowing users to set personalized font sizes for different websites.

Bellmac-32: The CMOS Gamble That Changed the World

In the late 1970s, Bell Labs engineers took a bold gamble, using cutting-edge 3.5-micron CMOS technology and a novel 32-bit architecture to create the Bellmac-32 microprocessor, aiming to surpass competitors like IBM and Intel. While not a commercial blockbuster, the Bellmac-32's pioneering use of CMOS laid the groundwork for the chips in today's smartphones, laptops, and tablets. Despite the high risks of this technology at the time, Bell Labs' teams across Holmdel and Murray Hill overcame manufacturing and testing challenges. Though it didn't become mainstream, the Bellmac-32's innovations in CMOS and chip architecture profoundly impacted the semiconductor industry, forging a new path.

Palantir CEO Slams Europe's Slow AI Adoption

At a Riyadh investment forum, Palantir CEO Alex Karp praised Saudi engineers for their meritocracy and patriotism, while criticizing Europe's slow AI adoption. He highlighted the US and the Middle East as leaders in AI implementation, contrasting this with Europe's lagging progress and what he perceived as a sense of resignation among its players. This is attributed to Europe's stringent AI regulations and its low market share in crucial AI infrastructure areas like raw materials, cloud infrastructure, and supercomputers. While Europe leads in AI semiconductor equipment manufacturing, its market share in these other areas is below 5%.

Obsidian's Supply Chain Security: A Cautious Approach

Obsidian, a note-taking app, employs a rigorous security strategy to mitigate supply chain attacks. This involves minimizing third-party dependencies, strictly version-pinning all dependencies with a lockfile and a thorough upgrade process (including line-by-line changelog reviews and extensive testing), avoiding postinstall scripts, and implementing a significant delay between dependency upgrades and releases to allow time for community and researcher detection of malicious versions. These measures significantly reduce Obsidian's vulnerability to supply chain attacks, ensuring user data security and privacy.

Calculating Earth's Radius with Geometric Algebra: A Sunset Photo Hack

2025-03-15

This article presents a clever method for calculating the Earth's radius using a single photograph of a sunset over a calm body of water. Building upon Robert Vanderbei's elegant trigonometric analysis, the author employs the more powerful system of geometric algebra to analyze the image. By constructing vector equations and leveraging properties of geometric algebra, such as the geometric product and wedge product, a concise formula for calculating the Earth's radius is derived. The method ingeniously uses the relationship between the sun's position and its reflection on the water, and the effects of Earth's curvature, ultimately yielding a result reasonably close to the actual value.

The Crisis of Academic Conferences: Formalism Stifles Innovation?

2025-04-28

In computer science, top academic conferences have become the primary metric for research value, but their increasing bureaucratization and formalism threaten the vitality of academic innovation. The article argues that conferences have devolved into annual 'promotion exams,' with reviews focusing more on formal rules than on the inherent value of research, stifling many promising, innovative works. The author calls for a change in conference review culture, shifting the focus back to academic innovation itself. Recommendations include eliminating unnecessary bureaucratic rules and entrusting decision-making to senior experts in the field to foster academic advancement.

Tesla's Cut-Rate Cybertruck RWD: A Cheap Lie?

Tesla has released a base rear-wheel-drive Cybertruck, but it's priced at a hefty $71,985, only $10,000 less than the dual-motor all-wheel-drive model. This version is significantly stripped down, featuring slower acceleration, smaller wheels, reduced towing capacity, simplified suspension, a missing tonneau cover, and a downgraded interior. While range is slightly improved, the overall value proposition is poor, failing to compete effectively with other electric trucks. Tesla's strategy appears to be a sales boost, but whether sacrificing features for sales will succeed remains to be seen.
