Sub-Pixel Motion Detection with Ferroelectric Polymer-Based Memristor

Sub-Pixel Motion Detection with Ferroelectric Polymer-Based Memristor

Researchers have developed a novel ferroelectric random-access memory (FeRAM) using solution-processed ferroelectric P(VDF-TrFE) thin films for sub-pixel motion detection. This FeRAM, based on a passive crossbar array of capacitors, leverages the nonlinear dynamics of ferroelectric domains to effectively eliminate sneak-path issues. By switching ferroelectric domains via controlled electric field polarity, the system stores and processes image information, directly extracting image differences. This enables applications like calculating derivatives of mathematical functions and identifying moving objects. The system boasts high accuracy, low power consumption, and eliminates the need for additional memory units, showing significant potential for applications in video surveillance and defect detection.

Developing iOS Apps on Non-Apple Devices: Legal Minefield

The possibility of building iOS apps on non-Apple devices has long been debated. This post highlights that the primary challenge is legal and licensing, not technical. Apple's Developer Program License Agreement explicitly forbids installing, using, or running iOS SDKs or other Apple software on non-Apple devices. While the Oracle v. Google case altered the copyright landscape regarding reverse engineering for compatibility, the author argues that deploying apps built on non-Apple devices directly to the App Store carries significant legal risk, with Apple retaining the right to terminate violating developer accounts.

Gonzalo Guerrero: A Transcultural Legend of the New World

Gonzalo Guerrero, a Spanish sailor from the early 16th century, was shipwrecked on the Yucatán Peninsula and taken captive by the Maya. He not only gained his freedom but rose to become a respected warrior under a Maya lord, marrying a Maya woman and fathering children, some of the first mestizos in the Americas. He famously refused offers to join the Spanish conquistadors, choosing loyalty to the Maya and participating in wars against the Spanish colonizers, ultimately dying in battle. His story is a compelling tale of transcultural assimilation, personal choice, and the complexities of the colonial era.

VC's Last Hope: An AI Bubble and Sam Altman

The Q1 2025 Venture Monitor reveals a moribund venture capital industry, except for AI, which is almost entirely reliant on OpenAI. High interest rates have dried up funding, leaving VCs scrambling and hoping for an AI miracle fueled by OpenAI's aggressive spending. The report blames Trump's tariffs, overlooking the industry's support for him. Early-stage funding is stagnant, many startups are dying, IPOs are rare, and exits are almost nonexistent. VCs are keeping existing companies afloat with late-stage funding and secondary sales. The future of venture capital remains uncertain and precarious.

AI Deciphers 2000-Year-Old Herculaneum Scroll: Unveiling Philodemus' Ethical Treatise

Using AI-powered 'virtual unwrapping', researchers have for the first time identified the title and author within a sealed Herculaneum scroll, PHerc. 172. The scroll has been confirmed as *On Vices* by the Greek philosopher Philodemus, an ethical treatise offering guidance on cultivating a virtuous life. This breakthrough, achieved by the Vesuvius Challenge and researchers from the University of Würzburg, earned them a $60,000 prize. While the author and title are clear, the scroll's precise place within the *On Vices* series (known to have at least 10 books) requires further investigation. This discovery offers valuable insights into Philodemus' ethical views and the complete *On Vices*, showcasing AI's transformative potential in humanities research.

Sandboxing Libraries: A Thorny Path to Security

This article delves into the significant challenges of building sandboxed libraries. The author explores threat modeling, memory tampering, cross-language interoperability, and code reuse. Even languages like Java struggle with complete sandboxing due to features like reflection, global methods, and native methods. Joe-E, a capability-based programming language, while severely restricting Java's functionality, offers valuable insights. However, this approach introduces the "God Object" problem, requiring a single object to control all permissions, contradicting good OOP principles. Chrome's Mojo system presents a process-based sandboxing solution, but faces challenges like unstable APIs, code reuse difficulties, and performance overhead. Ultimately, creating secure sandboxed libraries remains a complex and unsolved problem.

The Right to Disconnect: Do We Have the Freedom to Opt Out of AI?

AI is silently reshaping our lives, from curated newsfeeds to traffic management. But a critical question arises: do we have the right to live free from AI's influence? The article argues that AI's integration into essential services like healthcare and finance makes opting out incredibly difficult, leading to potential exclusion. Bias in AI systems exacerbates existing inequalities, widening the digital divide. Using Goethe's Sorcerer's Apprentice as a metaphor, the author warns against uncontrolled technological power. The piece calls for governments, businesses, and society to create AI governance frameworks that respect individual freedoms, improve digital literacy, and ensure everyone has a choice in engaging with AI, preventing AI from becoming a tool of control.

LCP eBook DRM: A Cautiously Optimistic Assessment

2025-05-09

Readium's LCP eBook DRM scheme allows offline reading after download, eliminating the need for constant online verification. It uses AES-256 encryption and is authorized via an .lcpl file containing decryption information. While the scheme relies on a proprietary decryption BLOB, its open ePub format and multi-reader support make it relatively secure and allow for offline backups. However, the bookseller can track reading devices and times, and forgotten passwords are unrecoverable. Furthermore, the long-term compatibility and security of the BLOB are questionable, and the risk of cracking remains. In short, LCP represents a relatively benign attempt at DRM, but its long-term security and level of user control require cautious assessment.

Bias-Free Dual H2 Production System: 4x Higher Efficiency Than DOE Target

Researchers have devised a novel bias-free dual hydrogen production system, replacing the energy-intensive oxygen evolution reaction with the cost-effective oxidation of furfural. The system consists of a highly efficient PtC/Ni/c-Si photocathode for water reduction and a copper anode for furfural oxidation, producing valuable furoic acid and hydrogen. This design cleverly harnesses the high photocurrent of the c-Si photocathode, eliminating the need for external bias and achieving a significantly higher hydrogen production rate than conventional water splitting. The solar hydrogen production rate is more than 8 times higher than previously reported bias-free PEC H2 production systems, far exceeding the US Department of Energy (DOE) target.

MCP: A Protocol in Need of a Major Overhaul?

This article presents a critical analysis of the Model Context Protocol (MCP). The author attempted to build an MCP server, only to find the documentation lacking, design decisions bizarre, and the HTTP transport options (SSE+HTTP and the so-called "Streamable HTTP") overly complex and confusing, far inferior to the simplicity and efficiency of WebSockets. The author argues that MCP's excessive flexibility leads to increased complexity, higher maintenance costs, and security risks. They suggest replacing the existing HTTP transport with WebSockets and simplifying the protocol design for improved usability.
