75% More Pedestrians Have Been Killed Since 2009. Giant Trucks and SUVs Are Why
**Summary of "75% More Pedestrians Have Been Killed Since 2009. Giant Trucks and SUVs Are Why" by The Drive** • **Main Thesis**: The increase in pedestrian fatalities since 2009 is linked to the rise of larger vehicles, particularly SUVs and pickups, due to changes in regulations and consumer preferences. • **Key Findings**: - Pedestrian fatalities have surged by 75% since 2009, with approximately 200 to 400 deaths annually attributed to the growth in vehicle size. - The shift to larger vehicles, especially those with higher hoods, has led to an estimated 3,000 pedestrian deaths from 2016 to 2024. - The increase in pedestrian deaths correlates with the hazards presented by the physical heft, height, and blind spots of today's bigger trucks and SUVs. • **Causes and Context**: - The trend towards larger vehicles began in the 1990s but was interrupted by the financial crisis in 2008. - Stricter emissions regulations and the "footprint model" introduced by the Obama administration encouraged automakers to produce larger vehicles to meet fuel economy standards. - The "Cash for Clunkers" program in 2009 also contributed to the shift towards newer, larger vehicles. • **Physics of Impact**: - Larger vehicles distribute force differently but increase the risk of deadly collisions due to their height and mass. - The height of vehicle hoods can cause pedestrians to be knocked down in front of the vehicle, leading to more severe injuries. • **Industry Response and Solutions**: - European regulations have influenced car design to make front-ends more pedestrian-friendly. - However, the increasing mass of vehicles, combined with their growing height, poses a significant safety risk. - Improved safety systems and crash testing, such as that conducted by Forensic Rock, can help mitigate these risks. • **Author's Insight**: The author highlights the unintended consequences of regulatory changes and consumer preferences, emphasizing the need for a balance between fuel efficiency, safety, and vehicle size. • **Source**: The article is based on a study by The New York Times and the Insurance Institute for Highway Safety, using federal and industry records, including never-before-examined data on vehicle dimensions. • **Why Saved**: This article provides crucial insights into the unintended consequences of regulatory changes and consumer trends in the automotive industry, with significant implications for pedestrian safety. It serves as a reminder of the importance of considering all aspects of vehicle design and their potential impacts on safety.

The work of landlord technology: The fictions of frictionless property management - Erin McElroy, 2024
**Summary of "The Work of Landlord Technology: The Fictions of Frictionless Property Management" by Erin McElroy, 2024** • **Main Thesis**: The author, Erin McElroy, challenges the narrative of landlord technology being a seamless, tenant-friendly solution. Instead, she argues that these systems often exacerbate power imbalances and create new forms of tenant surveillance and control. • **Fiction of Frictionlessness**: McElroy debunks the industry's claim of "frictionless" property management, highlighting that these technologies often introduce new complexities and barriers for tenants. • **Power Dynamics**: The author emphasizes that landlord technology reflects and reinforces existing power dynamics. It's not a neutral tool but a means for landlords to assert control over tenants' lives and spaces. • **Data Collection and Surveillance**: McElroy discusses how these technologies enable landlords to collect vast amounts of data about tenants, transforming them from customers into data subjects. This data can be used to profile, monitor, and potentially discriminate against tenants. • **Case Studies**: The author presents case studies of popular landlord technologies, such as smart locks, rent payment apps, and tenant screening services, to illustrate her points. These include: - **Smart Locks**: While marketed as convenient, they can also enable landlords to remotely lock out tenants or monitor their comings and goings. - **Rent Payment Apps**: These apps often charge tenants fees and can be used to track their financial behavior, potentially leading to evictions based on financial data. • **Gamification and Behavioral Modification**: McElroy notes how some landlord technologies use gamification to encourage tenants to engage with the platform, but this can also manipulate tenants into performing tasks that benefit the landlord, such as reporting maintenance issues. • **Counterarguments**: The author acknowledges that some technologies, like online maintenance request systems, can indeed improve tenant-landlord communication. However, she argues that these benefits are often overshadowed by the systems' more sinister aspects. • **Author's Background**: Erin McElroy is an assistant professor of geography at UC Santa Barbara, specializing in urban and social justice issues. Her work in tenant advocacy and research informs her critical perspective on landlord technology. • **Publication Context**: This article was published in 2024, reflecting the growing concern around the use of technology in residential rental markets and the potential for it to exacerbate housing inequality. • **Implications**: McElroy's work serves as a cautionary tale for tenants, policymakers, and tech developers, highlighting the need for critical evaluation of landlord technologies and the importance of tenant-centric design and regulation. • **Why Saved**: This article was saved as it provides a critical perspective on the growing use of technology in the rental market, offering insights into potential pitfalls and raising important questions about power, data, and housing justice. It's a valuable resource for anyone interested in understanding the complex dynamics of landlord technology and its impact on tenants.

Mapping LLM embeddings in three dimensions
**Summary of "Mapping LLM Embeddings in Three Dimensions"** - **Purpose**: The research explores visualizing and understanding Large Language Model (LLM) embeddings by mapping them in 3D space, aiming to provide insights into LLM's internal representations and improve interpretability. - **Methodology**: The authors use the t-SNE (t-Distributed Stochastic Neighbor Embedding) algorithm to reduce the high-dimensional embeddings to 3D, enabling visual exploration. - **Key Findings**: - **Clustering**: LLM embeddings cluster based on semantic similarity, with related words (e.g., 'king' and 'queen') close to each other in the 3D space. - **Manifold Structure**: Embeddings form a continuous, manifold-like structure, with semantically similar words lying on connected paths. - **Siamese Relationships**: Words with strong semantic relationships (e.g., 'Paris' and 'France') appear close together, forming 'siamese' pairs. - **Visualizations**: The authors provide interactive 3D visualizations, allowing users to rotate, zoom, and explore the embedding space. These visualizations can be found at <https://projects.stephenkay.co/llm-embeddings/>. - **Interpretability**: By examining the 3D maps, researchers can gain insights into LLM's understanding of language, such as its grasp of semantic relationships and analogies (e.g., 'man : king :: woman : queen'). - **Limitations**: The 3D visualization is a simplification of the high-dimensional embedding space, and some information may be lost or distorted during the dimensionality reduction process. - **Future Work**: The authors suggest exploring other dimensionality reduction techniques, dynamic embeddings, and incorporating task-specific information to enhance the visualizations' utility. - **Why Saved**: This research was saved due to its potential in improving our understanding of LLMs, enabling better interpretability, and facilitating more informed model development and fine-tuning. The interactive visualizations also provide a compelling way to explore and communicate LLM embeddings.

Hexagons and Hilbert curves – The headaches of distributed spatial indices | Hacker News
**Summary of "Hexagons and Hilbert curves – The headaches of distributed spatial indices" on Hacker News** • **Topic**: The challenges and complexities of using distributed spatial indices for efficient geospatial data processing, with a focus on hexagon and Hilbert curve-based approaches. • **Author**: The post is a comment by user 'jared' (Jared Moore), a software engineer with experience in geospatial data processing. • **Context**: The discussion follows a Hacker News article about a new geospatial database, sparking interest in the spatial indexing methods used by Jared. • **Hexagon-based indexing**: - **Idea**: Divide the world into hexagonal grids, each containing a fixed number of points. - **Advantages**: Even distribution of points, simple geometry, and efficient nearest neighbor search. - **Challenges**: Hexagons at the edges of the grid require special handling, and the grid size affects the search radius and query performance. • **Hilbert curve-based indexing**: - **Idea**: Map 2D spatial data to 1D space using Hilbert curves, preserving locality and enabling efficient range queries. - **Advantages**: Efficient range queries, no special handling for edges, and easy parallelization. - **Challenges**: Complex geometry, less intuitive than hexagons, and performance can degrade for high-dimensional data. • **Distributed spatial indexing**: - **Problem**: Traditional spatial indexing methods (e.g., R-tree, Quadtree) struggle with distributed data and high query loads. - **Approaches**: Use distributed databases (e.g., Apache Cassandra, Google Bigtable) with custom spatial indexing or rely on built-in geospatial extensions (e.g., PostGIS, MongoDB). • **Trade-offs**: Both hexagon and Hilbert curve-based indexing have trade-offs in terms of query performance, data distribution, and complexity. The best choice depends on the specific use case and data characteristics. • **Jared's experience**: He found that Hilbert curves worked well for his use case (processing large amounts of geospatial data in a distributed setting), but they required more computational resources and had a steeper learning curve. • **Key takeaway**: There's no one-size-fits-all solution for distributed spatial indexing. Both hexagon and Hilbert curve-based approaches have their merits, and the choice depends on the specific requirements and constraints of the project. • **Relevance**: This discussion is relevant for data engineers, geospatial data scientists, and anyone working with large-scale geospatial data in a distributed environment. It provides valuable insights into the trade-offs and challenges of different spatial indexing methods.

• **Purpose**: The user is looking for a physical display device that can show real-time status updates of their Netlify deploys, indicating the need for a convenient, centralized, and easily accessible monitoring solution. • **Requirements**: - Real-time updates: The display should instantly reflect the current status of deploys, including any ongoing or completed deployments. - Centralized view: It should show all active and recent deployments in one place, allowing the user to quickly grasp the overall deployment landscape. - Easy access: The display should be easily visible and accessible, ideally in the user's workspace or development environment. • **Potential Solutions**: - **Raspberry Pi with a Monitor**: By setting up a Raspberry Pi with a monitor, the user can run a dedicated application that fetches and displays Netlify deploy status using Netlify's API. This provides a low-cost, customizable, and always-on solution. - **Netlify's Web Interface**: While not a physical display, Netlify's web interface can be kept open on a secondary monitor or a dedicated device (like an old laptop) for real-time updates. However, this relies on an active internet connection and may not be as convenient as a dedicated display. - **Third-party Monitoring Tools**: Services like Datadog, New Relic, or Uptime Robot can be configured to monitor Netlify deploy status and display the information on a physical dashboard. These tools offer advanced features but may come with additional costs. • **API Details**: Netlify provides an API that allows developers to fetch deployment data, including status, build logs, and more. The API uses standard HTTP methods and returns JSON data, making it easy to integrate with various display solutions (e.g., Raspberry Pi, third-party monitoring tools). • **Example Setup (Raspberry Pi)**: To set up a Raspberry Pi for this purpose, the user would need to install Python and the `requests` library, create a script that fetches deploy data using Netlify's API, and configures the script to run continuously. The script could then display the data using a simple GUI library like `tkinter` or a more advanced one like `PyQt`. • **Limitations and Considerations**: - **Internet Connectivity**: The display solution relies on an active internet connection to fetch and display real-time data. - **API Rate Limits**: Netlify's API has rate limits, which may need to be considered when designing the display solution, especially if it needs to update frequently. - **Security**: When using a physical display, the user should ensure that their Netlify API token is kept secure to prevent unauthorized access to their account. • **User's Previous Interactions**: The user has previously interacted with Netlify's web interface and CLI for deployments but found them less convenient for monitoring purposes, leading to the search for a dedicated display solution. • **Future Use Cases**: The user plans to use this physical display not only for monitoring Netlify deploys but also as a starting point for creating a more comprehensive development environment dashboard, potentially including other tools and services they use.
