Pornhub Title Evolution: From 'Hot Blonde' to 'Incest'

This paper uses language embeddings to analyze the evolution of Pornhub homepage titles from 2008 to 2023. The study finds a shift from simple descriptions like "hot blonde" to content with more violent and incestuous themes. This change is linked to Pornhub's professionalization, commercialization, and changes in relevant laws and regulations. Using yearly centroid calculations and t-SNE visualization, the researchers reveal three distinct periods in title content and analyze keyword trends, such as the declining market share of terms like "Latina" and the significant increase in terms like "incest" and "rape." The research raises questions about the commercialization of the pornography industry and the direction of its content.

Leadership: The Importance of Consistent Messaging

2025-02-04

This article explores the challenges of effective communication in large organizations. A former COO's advice to the author – that leaders must repeatedly deliver the same message to ensure its impact – is central. Even simple messages from a CEO, via email or all-hands meetings, can fail due to skimming, absences, information distortion, and the forgetting curve. Effective communication demands empathy, understanding the audience's perspective, and utilizing multiple channels for consistent messaging. The author emphasizes the need for discipline and persistence – 'beating the drum' – to ensure team alignment and understanding.

Self-Driving a 1993 Volvo 940 (Part 1: Actuators)

2025-01-04

The author and friends are participating in the 2025 Carbage Run winter edition, a 6-day winter journey across Sweden to the Arctic Circle and back to Helsinki. Their car: a 1993 Volvo 940, almost devoid of electronics. To make it self-driving, they're retrofitting actuators: steering motor, brake booster, and accelerator servo. This post details the process of adapting an electric power steering system from a 2020 Toyota Corolla, replacing the vacuum-assisted braking system with a Bosch iBooster, and using an off-the-shelf RC servo for the accelerator. A Tesla radar sensor was also added. It's a challenging project, with future posts covering wiring and a custom ECU.

How Far Can You See on the Prairies?

Driving across the flat prairies can be monotonous, but the vast distance visible is captivating. With no obstructions, the horizon stretches out, and simple geometry reveals it's approximately 4.7km away. This is roughly the distance of a 5km race, making it surprisingly impressive. But are there even farther sightlines on Earth? This leads to a contemplation of Earth's curvature and the limits of human vision.

Blazing Fast Cuckoo Filter Lookups in C# with Bit Twiddling

Blazing Fast Cuckoo Filter Lookups in C# with Bit Twiddling

While implementing a Cuckoo Filter in C#, the author significantly optimized lookup speed by cleverly replacing a 4-byte bucket with a 32-bit integer and employing bit manipulation tricks. Initially, a byte array required looping through four bytes per bucket. Switching to a uint array and using bit shifting improved performance by roughly 35%. However, the author's final optimization, a branchless bit manipulation technique to directly check for a target byte, resulted in over 60% faster positive lookups and more than double the speed for negative lookups. While readability decreased slightly, the performance gains are substantial, making this a worthwhile optimization strategy.

US-Funded International Broadcasters Under Threat

For decades, the U.S. government has funded international broadcasters, providing news and information to authoritarian countries and countering censorship. However, a new appointee in the Trump administration is attempting to defund and dismantle these outlets, leading to legal battles. This move not only threatens the survival of these broadcasters but also allows countries like China and Russia to fill the information void with their propaganda, posing a threat to U.S. national security. The cuts also jeopardize America's efforts to combat censorship and disinformation globally.

Japan's Citizen-Created Sex Offender Map Sparks Legal Debate

Japan's Citizen-Created Sex Offender Map Sparks Legal Debate

In response to a lack of a national sex offender registry and numerous cases of child sexual abuse, a website called Amyna has emerged in Japan, offering a map of alleged sex offenders. Created by a former UN worker, Amyna aims to fill the gap in official systems, but its legality is highly questionable. Japan's strict personal information protection laws heavily restrict data disclosure, potentially leaving Amyna vulnerable to privacy violation claims. While the site argues it protects children, its lack of robust verification processes and handling of sensitive information risks false accusations and secondary victimization. The initiative has sparked a wide-ranging debate about privacy, citizen rights, and government responsibility, highlighting shortcomings in Japan's legal framework for child protection.

Earth's Inner Core May Have Changed Shape: Seismic Waves Reveal a Twist

Earth's Inner Core May Have Changed Shape: Seismic Waves Reveal a Twist

New research using seismic wave data suggests Earth's solid inner core may have altered its shape over the past two decades. Analyzing seismic waves from 128 earthquakes off South America (1991-2023), researchers found discrepancies between waves passing through the core and those that didn't. This indicates a change beyond just rotational speed. The change could stem from magnetic forces in the outer core's convection acting on the inner core's less viscous edge, or interactions between the inner core and the lower mantle. However, other factors like outer core changes, inner core convection, or molten material eruptions remain possible explanations. This study offers a new perspective on understanding the Earth's deep interior evolution, but further research is needed for confirmation.

Programmer's Abstract Machine Models: Understanding the Meta of Software

This article explores the "Abstract Machine Models" (AMMs) programmers utilize when writing software. The author recounts personal experiences designing programming tools, highlighting the intimate connection between hardware architecture and programming languages. They argue that a programmer's mental AMM isn't simply a language or hardware model but an abstraction incorporating extra-functional behaviors like time, memory, and I/O. Analyzing languages like Haskell, the author distinguishes between descriptive and specification models and details AMMs' application across various programming languages and hardware platforms. The article further explores AMMs' roles in evaluating programming skills and building software ecosystems, analyzing how different types of language designers influence AMMs. Finally, the author summarizes AMMs' importance in software engineering and points towards future research directions.
