The Alabama Landline That Keeps Ringing
(The Alabama Landline That Keeps Ringing)

Summary: The Foy Information Desk at Auburn University

The Foy Information Desk at Auburn University has been answering public calls for 70 years, originally established by then-dean James E. Foy. Students at the desk handle a variety of inquiries, ranging from the bizarre to the mundane, like legal questions about death or the net worth of celebrities.

The desk has evolved from a resource with physical books to a modern setup with computers, but its phone number remains the same. Many callers are not internet users, and the student workers provide a non-judgmental service for everyone, including regular callers like Beulah, who often has long conversations about her pets.

The desk's training is minimal, with basic guidelines for handling calls. Student workers often develop imagined profiles of their callers based on their voices and accents, forming connections even without knowing much about them.

Cora, a senior at the desk, reflects on her meaningful interactions with callers, emphasizing the importance of being there for those who need someone to talk to. The students take pride in their respectful and caring approach, seeing their role as a vital resource in the community.

In kids, EEG monitoring of consciousness safely reduces anesthetic use
(In kids, EEG monitoring of consciousness safely reduces anesthetic use)

A recent clinical trial in Japan involving over 170 children aged 1 to 6 found that monitoring brain waves with electroencephalograms (EEG) can help anesthesiologists safely reduce the amount of sevoflurane anesthesia given during surgery. This method led to faster recovery times and fewer cases of post-operative delirium compared to standard dosing.

The study, co-authored by Emery N. Brown from MIT, showed that children receiving EEG-guided anesthesia woke up 21 minutes earlier and had breathing tubes removed 3.3 minutes sooner than those on standard protocols. Additionally, only 21% of the EEG-guided group experienced signs of post-anesthesia delirium, compared to 35% in the standard group.

Using less sevoflurane benefits both patient health and reduces costs, as less time in post-acute care can save around $750 per case. This approach also has environmental advantages due to the reduced use of a potent greenhouse gas. The findings suggest that integrating EEG training into anesthesiology practices could enhance patient care.

What went wrong with wireless USB
(What went wrong with wireless USB)

The article discusses the history and challenges of wireless USB technology, specifically focusing on its rise and fall in the market. Here are the key points:

  1. Background: The author reflects on an attempt to make a Palm OS smartwatch mobile through wireless USB technology. Wireless USB was once a promising idea but faced many hurdles.

  2. Technological Roots: Wireless USB was built on ultra wideband (UWB) technology, which allows high-speed data transfer over short distances using weak signals. Competing standards, particularly between MB-OFDM and DS-UWB, caused confusion and market fragmentation.

  3. Development of Wireless USB: Intel and other companies formed the Wireless USB Promoter Group, aiming to create a standardized version of wireless USB. However, two competing technologies (CW-USB and CF-USB) emerged, leading to confusion and complexity.

  4. Market Challenges: Despite initial hype, wireless USB struggled in the market. Many devices required additional dongles, and real-world performance rarely matched the promised speeds. This led to limited adoption, as consumers found it easier to use existing technologies like Bluetooth and Wi-Fi.

  5. Failed Products: Several products were developed, but many faced poor reviews and limited functionality. Ultimately, the lack of compatible devices and the complexity of installation contributed to their failure.

  6. Legacy: By 2008, wireless USB technology had mostly faded from the market. The article concludes that while UWB technology is still used for specific applications (like tracking), wireless USB itself did not succeed due to superior alternatives like Bluetooth and Wi-Fi, which have since become the standard for wireless data transfer.

In summary, wireless USB had potential but failed to gain traction due to competition, technical complexities, and the rapid advancement of other wireless technologies.

The Speed of VITs and CNNs
(The Speed of VITs and CNNs)

Summary: On the Speed of ViTs and CNNs

Key Concepts:

  • Two main architectures in computer vision are Convolutional Neural Networks (CNNs) and Vision Transformers (ViTs).
  • CNNs process images using convolutions, while ViTs divide images into patches and apply self-attention.

Main Arguments:

  1. ViTs Scale Well:

    • ViTs can efficiently process images up to 1024x1024 pixels, which is sufficient for most applications.
    • Benchmarking shows that ViTs can be faster than CNNs on modern GPUs and are more memory efficient.
  2. Resolution Needs:

    • Most tasks do not require very high resolution. Suggested resolutions are:
      • 224 pixels for natural images.
      • 448 pixels for images with text.
      • 896 pixels for desktop screens/documents.
    • Higher resolution mainly serves aesthetic purposes and is not necessary for model performance.
  3. Model Capacity and Performance:

    • Increasing image resolution also increases the model's capacity, which affects performance.
    • Higher capacity often leads to better results, but much of the performance gain seen with increased resolution is due to this capacity, not just resolution.
  4. Local Attention:

    • A technique called local attention can make ViTs faster and more memory efficient by focusing on smaller windows of the image.
    • This method is simple and enhances the efficiency of ViTs compared to CNNs.
  5. Training and Learning:

    • While this discussion focuses on inference speed, ViTs also show efficiency during training.
    • Some recent techniques work better with ViTs than CNNs, highlighting advantages in learning capabilities.

Conclusion:

  • Both architectures have their strengths, but ViTs offer significant benefits in speed, efficiency, and adaptability for many computer vision tasks. The choice between them should depend on specific needs rather than a strict preference for one architecture over the other.

Codd's cellular automaton, created by Edgar F. Codd in 1968, is a simplified version of a self-replicating machine that uses only eight states, compared to the 29 states of John von Neumann's original design. Codd aimed to demonstrate how a machine could reproduce itself with fewer components.

Historically, von Neumann's work in the 1940s and 50s laid the groundwork for self-replicating automata. Codd refined this concept, while other researchers, like Edwin Roger Banks and John Devore, contributed further advancements. Banks introduced a four-state automaton, and Devore simplified Codd's design. Christopher Langton later modified Codd's CA to create Langton's loops, which could replicate but not compute universally.

Codd's cellular automaton features eight states with rotational symmetry and utilizes specific signal trains to perform tasks like extending and retracting components. Although Codd designed a self-replicating computer, it wasn't fully implemented until 2009 by Tim Hutton, who corrected some errors in the original design.

The text discusses Brian Eno's ideas and their implications for democracy, connecting them to the work of political scientist Adam Przeworski. Eno doesn't have an explicit theory of democracy, but his views on art can inform our understanding of how democracy should function. Przeworski's theory suggests that democracy relies on political parties accepting electoral defeat due to self-interest and uncertainty about future elections. This creates a stable system as parties expect to return to power eventually.

However, the author argues that this traditional view fails to explain current democratic decline, especially in the U.S. They propose a "dynamical model of democracy," which acknowledges that democratic systems must adapt over time to changing environments and internal disagreements. Eno's approach emphasizes generating variety and adaptability rather than rigid structures, similar to how diverse musical performances can arise from simple instructions.

The text stresses the importance of balancing stability with the need for diversity in democratic systems, suggesting that a successful democracy should encourage a range of perspectives and solutions to complex problems. Additionally, it warns against polarization, which can stifle diversity and weaken democracy. The author believes that Eno's ideas can provide useful guidance for rethinking democratic practices to promote adaptability and responsiveness in political systems.

He feels that relying on computers ties him to energy corporations, which he criticizes for harming the environment. Instead, he prefers to use horses for farming and a manual typewriter for writing, valuing the personal connection and critique he receives from his wife, who types his work.

Berry lists several reasons for his choice: he believes his writing should not depend on harmful energy sources, he values the simplicity and familiarity of his current tools, and he does not see computers as essential for better writing. He also argues that technological advancements often replace valuable human relationships and that he wants to limit his involvement with damaging technology.

In response to Berry's essay, some readers defend their own use of computers, arguing they are practical tools that can support environmental activism. However, Berry contends that many environmental problems stem from consumer habits, and he advocates for reducing personal consumption as a more direct way to address these issues.

Overall, Berry emphasizes the importance of being mindful about technology's impact on both personal life and the environment, suggesting that true progress should not come at the expense of our relationships or ecological integrity.

DotnetSnes: Library allowing to use C# to create SNES ROMs
(DotnetSnes: Library allowing to use C# to create SNES ROMs)

DotnetSnes Overview

DotnetSnes is a tool that lets developers use .NET languages to create real SNES (Super Nintendo Entertainment System) ROMs.

How It Works:

  • DotnetSnes provides a .NET library that simplifies creating SNES games.
  • When you compile a project using DotnetSnes.Core, it converts the resulting DLL to C code using the Dotnet To C transpiler (dntc).
  • This C code is then compiled with the PvSnesLib SDK to produce a working SNES ROM.
  • Due to SNES limitations, developers may need to use lower-level programming techniques instead of standard C# practices.

Getting Started:

  1. Environment Setup:

    • Use WSL (Windows Subsystem for Linux) Ubuntu for the best experience.
    • Clone the DotnetSnes repository using SSH to access all necessary submodules.
    • Update and install required dependencies: cmake, g++, dotnet-sdk-8.0.
  2. Preparing the SDK:

    • After cloning, run git submodule update --init --recursive to set up dependencies.
    • Go to the pvsneslib directory and run make to build the toolchain.
  3. Examples:

    • Hello World: A simple example that creates a basic SNES ROM displaying text.
    • LikeMario Game: A more complex example demonstrating game logic, graphics, and input handling.

Creating a New Project:

  • Start a new .NET class library project and reference DotnetSnes.Core and Dntc.Attributes libraries.
  • Define the entry point with a Main() function and add specific attributes for transpilation.
  • Create a Makefile for the build process and include game assets as needed.
  • Write a manifest.json file to guide the transpiler on your project settings.

Building Your Project:

  • After setting everything up, use the make command in your project directory to compile and generate the SNES ROM.

This guide provides a simplified path for developing SNES games using DotnetSnes, outlining setup, examples, and project creation steps.

A Survey of AI Agent Protocols
(A Survey of AI Agent Protocols)

The rapid growth of large language models (LLMs) has led to their use in many fields like customer service, content creation, data analysis, and healthcare. However, a major challenge is that there is no standard way for these LLM agents to communicate with each other or with external tools. This makes it hard for them to collaborate and handle complex tasks effectively.

To address this, a unified communication protocol is needed, which would improve interactions between agents and tools and promote teamwork. This paper offers a detailed analysis of existing communication protocols for LLM agents, categorizing them into two types: context-oriented versus inter-agent protocols and general-purpose versus domain-specific protocols. It also compares the performance of these protocols based on factors like security, scalability, and speed.

Furthermore, the paper discusses future developments in agent protocols, highlighting important features for next-generation systems, such as adaptability, privacy, and group interactions. It suggests trends towards layered architectures and collective intelligence. This work aims to guide researchers and engineers in creating better communication systems for intelligent agents.

The US has approved CRISPR pigs for food
(The US has approved CRISPR pigs for food)

The U.S. has approved a new type of pig that is genetically edited using CRISPR technology to be resistant to a virus called porcine reproductive and respiratory syndrome (PRRS), which is harmful to piglets. This advancement by the British company Genus means these pigs can now enter the food market.

Most pigs in the U.S. are farmed in confined spaces, and PRRS leads to significant economic losses—over $300 million annually. The CRISPR pigs have been engineered to lack the receptor that the PRRS virus uses to infect cells, making them almost entirely immune to the virus.

While gene editing in humans has raised ethical concerns, modifying pigs is viewed more favorably because it offers clear financial benefits. This breakthrough could help reduce virus transmission in livestock, which is important for preventing potential pandemics.

Genus's stock value increased significantly following the approval, and the company hopes to sell gene-edited pork in the U.S. by next year. They are also seeking approvals in other countries like Mexico, Canada, Japan, and China. There are currently no plans to label the pork as genetically engineered.

(We know a little more about Amazon's satellites)

Amazon recently launched its first production satellites for the Kuiper broadband network, which are different in design from SpaceX's Starlink satellites. The launch took place on April 28, 2025, using a ULA Atlas V rocket, but initial media coverage was limited, resembling a secret military launch. Amazon later released a video showing the satellites deploying in orbit, marking the first public view of the Kuiper satellites since the project was announced in 2019.

The Kuiper satellites are trapezoidal and are designed to operate in low Earth orbit, with plans to launch a total of 3,232 satellites over the coming years. This is part of Amazon's effort to compete in the satellite broadband market, where SpaceX currently leads with over 7,300 Starlink satellites.

Unlike SpaceX, which has been open about its satellite designs, Amazon has kept details about Kuiper under wraps. The satellites were released individually into orbit, with their deployment staggered over about 15 minutes. Amazon's head of Project Kuiper, Rajeev Badyal, previously worked at SpaceX, where he was involved in the early Starlink development.

The total mass of the 27 Kuiper satellites launched was approximately 34,000 pounds, making it the heaviest payload ever delivered by the Atlas V rocket. Each satellite is estimated to weigh between 1,185 and 1,259 pounds.

Surprisingly simple method makes a low-cost, tuneable liquid lens
(Surprisingly simple method makes a low-cost, tuneable liquid lens)

Researchers in the Philippines have developed a simple and cost-effective method to create adjustable liquid lenses using water droplets. This new approach is inspired by the shape of a water droplet, which can be manipulated to change its curvature and focus by varying the volume of water.

Unlike traditional glass lenses, which have fixed shapes and require complex setups to change their focal length, these liquid lenses can be adjusted easily without any moving parts. The researchers achieved this by coating a glass slide with a water-repellent material (PVC), allowing the droplets to maintain a spherical shape. By adding more water to the droplet, they found that the focal length increased linearly, from 1.3 mm to 7.6 mm as the droplet size increased.

This method provides a flexible and low-cost option for educational and laboratory experiments, making it easier for students and researchers to explore optical systems. The researchers believe this technique could serve as a foundation for developing more advanced liquid lens technologies in the future.

Bloom Filters
(Bloom Filters)

Summary of Bloom Filters

Bloom filters are a data structure created to efficiently check if an item is part of a set, using a probabilistic method. This allows for quick rejection of non-member items while minimizing time and space usage. Proposed by Burton Bloom in 1970, Bloom filters are useful in scenarios where most queries will not find the item.

Key Features:

  • Probabilistic Nature: If the Bloom filter indicates an item is not present, it's certain that it isn't. If it indicates presence, there could be a small chance of a false positive.
  • Efficiency: They are particularly effective when many checks return negative results, speeding up processes by avoiding unnecessary disk reads.

How It Works:

  • A Bloom filter consists of a bit array and multiple hash functions.
  • To insert an item, it is hashed multiple times, and the resulting bit positions are set to 1.
  • To test for membership, the item is hashed again, and if all corresponding bits are 1, it may be present (with a chance of error).

Implementation:

  • A simple implementation in Go uses a bit array to store membership information and applies hashing to manage items.
  • Parameters like the size of the array and the number of hash functions can be calculated based on the expected number of items and the desired false positive rate.

Practical Example: For a system storing 1 billion items with a 1% error rate, the Bloom filter would need about 9.6 billion bits and would allow for fast membership testing, greatly reducing the need for slow disk reads.

Mathematical Insights: The filter's performance can be mathematically analyzed to determine optimal settings for size and hash functions, ensuring minimal false positive rates.

Overall, Bloom filters are valuable in applications where space and speed are critical, particularly in data storage systems.

The article discusses the decline of tech jobs, termed "enshittification," where tech workers, once highly valued and well-compensated, are now facing deteriorating working conditions. For years, tech workers enjoyed high salaries and perks due to their scarcity and productivity. However, as layoffs increase—over half a million in the U.S. since 2023—workers are losing their leverage.

Tech companies, like Meta and Amazon, are cutting jobs while increasing executive bonuses, expecting remaining employees to take on more work for less pay and fewer benefits. This shift reflects a broader trend where tech workers, previously seen as peers to their bosses, are becoming more like other exploited workers in different industries.

The concept of "vocational awe" is discussed, highlighting how tech workers felt their work was vital, leading them to accept unfavorable conditions. However, as companies push for more productivity, workers are realizing they are being exploited. The article argues that tech workers must unite and organize, similar to workers in other sectors, to regain their rights and improve their labor conditions.

In summary, the tech industry is experiencing a significant shift where once-privileged workers are now facing exploitation, and unionization may be the only way to combat this trend.

New research from the University of Washington challenges the belief that strong math skills are essential for learning programming. Instead, it suggests that language skills and problem-solving abilities are more important. A study involving 42 participants learning Python through an online course found that those with better language aptitude learned the language faster and performed better overall, with language skills explaining nearly 20% of the learning rate, compared to just 2% for math skills.

The study also used brain activity measurements, showing that certain brain patterns linked to language learning were associated with better programming outcomes. These findings indicate that programming may be more closely related to language learning than previously thought, which could help change perceptions about who can be successful in coding.

This research has implications for education, suggesting that removing advanced math prerequisites for computer science could make the field more inclusive, particularly for women, who often excel in language skills. As programming becomes increasingly necessary in various jobs, it may be time to rethink how programming is taught and to focus more on language and creativity rather than strict math skills.

A PostgreSQL planner semi-join gotcha with CTE, LIMIT, and RETURNING
(A PostgreSQL planner semi-join gotcha with CTE, LIMIT, and RETURNING)

The author discovered an issue in PostgreSQL when using a Common Table Expression (CTE) with a DELETE statement that includes a LIMIT. The goal was to delete one task from a task_queue table for a specific queue_group_id and return the associated item_id. However, sometimes the query returned multiple item_ids instead of just one, despite the LIMIT.

The unexpected behavior was traced back to the query planner's execution strategy. Instead of executing the subquery with LIMIT 1 just once, the planner executed it multiple times, leading to multiple rows being deleted and returned. This was due to the planner using a Nested Loop Semi Join, which correlated the DELETE operation with the subquery, causing it to run the LIMIT 1 for each candidate row found.

The intermittent nature of the issue was explained by the planner's dependency on table statistics and data distribution, which could change between runs, affecting the execution plan.

To resolve the problem, the author suggested restructuring the query to avoid using a CTE. By directly using a subselect in the WHERE clause of the DELETE statement, the query more clearly communicated the intent to the planner, ensuring that the LIMIT was applied globally.

The key takeaway is to be cautious when using CTEs with DELETE or UPDATE statements that include LIMIT, and to always check the query plan with EXPLAIN ANALYZE to ensure the desired behavior is achieved.

The Totalitarian Buddhist Who Beat SIM City (2010)
(The Totalitarian Buddhist Who Beat SIM City (2010))

Summary: The Totalitarian Buddhist Who Beat Sim City

The article discusses Vincent Ocasla, a 22-year-old architecture student from the Philippines, who spent four years creating a complex city in Sim City called Magnasanti. Unlike typical gameplay, Vincent's approach is more artistic, using the game to explore themes of control and societal issues.

Magnasanti has a population of six million, but its citizens live in a dystopian state with high pollution and no essential services, reflecting the negative consequences of focusing solely on efficiency and profit. Vincent draws inspiration from the Buddhist concept of the Wheel of Life and critiques how society can become trapped in cycles of control and mediocrity.

He emphasizes that while his city looks orderly, it hides many problems, mirroring real-world issues. Vincent does not play other games anymore, feeling they lack purpose. He also clarifies that he does not have any mental disorders, just a passion for his unique project in Sim City.

RustAssistant: Using LLMs to Fix Compilation Errors in Rust Code
(RustAssistant: Using LLMs to Fix Compilation Errors in Rust Code)

Summary: RustAssistant: Using LLMs to Fix Compilation Errors in Rust Code

The paper discusses Rust, a programming language known for its safety features, making it a good choice for low-level systems programming compared to C/C++. However, Rust has a steep learning curve due to its complex features. To help developers, the authors introduced a tool called RustAssistant, which uses Large Language Models (LLMs) to automatically suggest fixes for compilation errors in Rust code.

RustAssistant combines various prompting techniques and interacts with the Rust compiler to achieve about 74% accuracy in fixing real-world compilation errors from popular Rust projects. The tool works by first capturing detailed compiler error messages, then extracting relevant code snippets, and finally sending this information to an LLM to generate a suggested fix. If the fix doesn't completely resolve the issue, RustAssistant iteratively refines the solution until the code compiles correctly.

The paper also provides a dataset of Rust compilation errors for future research and highlights the potential of LLMs to assist programmers in overcoming challenges related to Rust's advanced features. Overall, RustAssistant aims to ease the process of coding in Rust, making it more accessible for developers.
