This paper presents PhyloLM, a method that uses phylogenetic algorithms to analyze Large Language Models (LLMs). It measures how similar LLM outputs are to each other, creating a metric for their relationships. This metric helps create dendrograms, which effectively show the connections between 111 open-source and 45 closed models. Additionally, the method can predict how well these models will perform on standard tests, making it a useful tool for estimating LLM capabilities quickly and cheaply, even without detailed training data. In summary, PhyloLM translates concepts from population genetics to help evaluate and understand LLMs better.

Summary of Galaxian 3: Project Revival

Namco created Galaxian 3: Project Dragoon, a massive arcade game for 28 players, which debuted in 1990 in Japan. A smaller 16-player version was released in 1991, followed by a six-player version in 1992, which became more widely available. A sequel was released in 1994. Unfortunately, many of these machines were later converted to a different game, leading to the loss of many original components.

As of 2025, only four GT-6 versions remain, with one located in an arcade in New Hampshire. A team of enthusiasts is working to repair and preserve this machine, focusing on fixing player inputs and restoring the projectors.

In March 2024, the team discovered that only two player controls were working and several sound issues were present. They took some electronic components back to California for further testing. During a follow-up trip in March 2025, the team successfully repaired player inputs by adding grounding and replacing faulty components.

The team also worked on the projector systems and secured a replacement projector. Despite some ongoing issues, they achieved significant progress in restoring the game and are hopeful for its future operation. However, they recommend waiting to play the game until it is fully stable. Future improvements are planned, including servicing power supplies and optimizing projectors.

The text describes a particularly complex and problematic __init__ method in Python, specifically related to a class called FooBarWidget. The author encountered an issue while writing a test for this class, which occasionally failed due to an unexpected error involving an attribute called should_exit.

Here's a simplified summary of the key points:

1. Test Failure: The author wrote a test for FooBarWidget that sometimes failed with an AttributeError instead of the expected AssertionError, indicating that the should_exit attribute was not set.

2. Class Structure: The FooBarWidget class inherits from FooWidget, which correctly initializes should_exit. However, the issue arises because FooBarWidget's __init__ method is unusual.

3. Crazy Initialization: In FooBarWidget, the __init__ method starts a new thread to call the parent class's __init__. This means that if the FooBarWidget instance is closed too quickly, the parent class's initialization may not complete, leading to the error.

4. Reason for Design: The design choice was made to avoid blocking the main thread when creating a zmq.Socket, as these sockets cannot be moved between threads. This unconventional approach solves a threading issue but complicates the code significantly.

5. Conclusion: The author reflects on the chaos caused by this design, expressing a mix of horror and disbelief at the complexity introduced by this method of initialization.

Summary: The History and Risks of Nitrous Oxide Use

Nitrous oxide, often called laughing gas or “whippets,” has a long history as a recreational drug. Initially popular among 19th-century philosophers and poets, it is now being widely used by teens, particularly through products like Galaxy Gas, which is marketed for culinary use but is inhaled for a quick high. Concerns have been raised by artists and public health experts about its availability and the risks it poses to young users.

While nitrous oxide has legitimate medical and culinary applications, its recreational use can lead to serious health issues. Inhaling the gas can cause euphoria but may also result in dizziness, unconsciousness, and long-term cognitive problems due to oxygen deprivation. Additionally, it disrupts vitamin B12 metabolism, potentially leading to anemia and neurological complications with heavy use.

The resurgence of nitrous oxide use is fueled by social media trends, with videos showcasing its effects, which may mislead young people about its dangers. Despite some states beginning to regulate its sale, enforcement is challenging, and the substance remains easily accessible, often in smoke shops and online.

As the debate over regulation continues, experts emphasize the need for parental guidance and education about the risks associated with nitrous oxide, rather than relying solely on legal restrictions.

Summary of "Against Transparency" by Cory Doctorow

In California, warnings about chemicals that may cause cancer (due to Prop 65) are everywhere, but they often go ignored because almost everything triggers these warnings. The intent was to inform consumers, but the complexity of determining risk makes this ineffective. Instead of just warning about potential dangers, companies should be required to take steps to minimize risks.

The piece argues that while transparency (like privacy policies) is important, it isn't enough. Most people do not read these policies, which often contain legal jargon that can be misleading or harmful. Doctorow suggests that instead of relying on warnings and policies, we need stronger regulations to protect consumers, similar to how we banned dangerous products in the past.

He highlights the need for smarter regulations that allow consumers to engage with products and services without constantly worrying about hidden dangers. The Consumer Finance Protection Bureau (CFPB) is praised for its efforts to protect consumers, but there is concern about powerful individuals and companies trying to undermine such protections.

Ultimately, Doctorow advocates for a legal framework that prioritizes consumer safety over the interests of companies looking to exploit fine print and loopholes.

Iron Fertilization Summary

Iron fertilization is a method aimed at reducing carbon dioxide in the atmosphere by adding iron to the ocean's surface to promote the growth of phytoplankton. These tiny organisms use sunlight and carbon dioxide to produce food and oxygen, similar to land plants. While oceans have many nutrients, iron is often lacking, which limits phytoplankton growth.

When iron is added to the ocean, it can trigger large blooms of phytoplankton that absorb significant amounts of carbon dioxide. Natural events, like dust storms or volcanic eruptions, have shown that iron-rich materials can lead to these blooms and help lower atmospheric carbon levels. Historical climate data supports the idea that iron-rich dust has influenced global temperatures.

Research has shown that adding iron can lead to changes in phytoplankton communities, particularly increasing diatoms, which are larger and more effective at capturing carbon dioxide. However, there are concerns about potential harmful algal blooms and the ecological impact of altering nutrient distribution in the ocean.

Past experiments with iron fertilization faced skepticism due to unknown outcomes, but scientists are revisiting this method as a possible solution for climate change. They are developing guidelines for research to ensure transparency and assess the effects of iron addition. New technologies help monitor the carbon removal process in the ocean.

While iron fertilization could be a cost-effective approach to tackling excess carbon dioxide, it is crucial to continue reducing fossil fuel use simultaneously.

The article discusses best practices for using object storage, which has become a popular choice for storing large data in the cloud since its launch in 2006. Here are the key points:

1. Latency Issues: Object storage can have unpredictable latency, often showing a long tail in response times. This means that while most requests are quick, some can be very slow, affecting overall performance.

2. Hedging Strategies: To mitigate latency, you can use "hedging," where you send multiple requests at once or retry requests if they exceed a certain time limit. This can significantly improve response times at the cost of increased requests.

3. Caching: Implementing a cache for frequently accessed data can reduce latency and overall costs. The cost-effectiveness of caching depends on your specific workload.

4. Horizontal Scaling: Instead of reading an entire object with one request, you can split the read across multiple connections or requests. This parallelism can maximize throughput, especially if using a distributed cache.

5. Design Considerations: There is no one-size-fits-all solution; understanding your system's behavior through modeling and measurement is crucial. Tailoring your hardware and system design to the specific needs of your workload can lead to better performance.

In summary, using object storage effectively involves understanding its unique characteristics, implementing strategies to handle latency, and optimizing data access through caching and parallel reads.

Astronomers using the Hubble Space Telescope and other observatories have discovered that a massive star, 25 times the size of our sun, likely turned into a black hole without exploding as a supernova. Instead of the expected bright explosion, the star quietly collapsed under its own gravity in a process called a "failed supernova."

This finding suggests that up to 30% of massive stars may end their lives this way, which could explain why we rarely observe supernovae from the most massive stars. Researchers, including those from The Ohio State University, concluded that the star, known as N6946-BH1, disappeared from view after briefly brightening in 2009. They detected some infrared light from the area, indicating possible debris falling into the black hole.

This research could change our understanding of how very massive black holes form, as it suggests they might form more easily without the supernova process. The study involved collaboration among several institutions and was supported by the National Science Foundation.

Summary:

Recent discoveries of microbes living deep within the Earth's crust are reshaping our understanding of life and its evolution. These tiny organisms, referred to as "intraterrestrials," thrive in extreme conditions without sunlight or oxygen, relying instead on chemical processes involving various elements, including toxic substances like arsenic and radioactive uranium.

Intraterrestrials can live for hundreds of thousands or even millions of years, raising questions about how they evolve given their slow reproduction rates. Their long lifespans allow them to adapt to geological changes over vast timescales, rather than the shorter cycles we typically associate with evolution.

These microbes play a crucial role in Earth's ecosystems by regulating oxygen levels and detoxifying pollutants. They could also significantly influence how the planet responds to climate change, particularly as thawing permafrost releases carbon into the atmosphere.

Additionally, the potential for deep-sea mining raises concerns about the impact on these ecosystems. Mining could destroy habitats that support microbial life and disrupt the vital processes they contribute to ocean health.

Overall, the study of intraterrestrials is still in its early stages, but it holds promise for understanding life on Earth and its relationship with our environment.

A judge in Nevada has declared the practice of "tower dumps," where law enforcement collects extensive personal data from cell towers, unconstitutional. Tower dumps allow police to access information on all phones connected to a tower over a certain time, which can include thousands of users, violating privacy rights protected by the Fourth Amendment.

In a case involving Cory Spurlock, who faces charges related to drug dealing and a murder-for-hire scheme, police used a tower dump to link his phone to the crimes. Spurlock's lawyers argued that this constituted an illegal search. The judge, Miranda M. Du, agreed that a tower dump is a search and that the warrant used was overly broad, but decided not to suppress the evidence due to the police acting in good faith.

This ruling is significant as it is the first of its kind in the Ninth Circuit, though a similar ruling occurred in Mississippi earlier. The issue may eventually reach the Supreme Court, especially since the Court has previously ruled that accessing cell phone location data without a warrant violates the Fourth Amendment. The tower dump in Spurlock's case included data from 1,686 users, many of whom had not consented to share their location.

A new ASN.1 API for Python is being developed to improve performance and reduce security risks associated with ASN.1 parsing in cryptography and networking. ASN.1 (Abstract Syntax Notation One) is crucial for many internet protocols and cryptographic schemes but has historically led to vulnerabilities due to its complex encoding rules.

Key points about the new API include:

1. Performance Improvement: The API will utilize a Rust-based ASN.1 parser, which will offer performance closer to native code, unlike existing pure Python implementations that are slower.

2. Differential Reduction: By using a single parser already integrated into PyCA Cryptography for X.509, the new API aims to minimize the risk of inconsistencies that can lead to security issues.

3. Modernized Interface: The API will feature a more user-friendly design using Python's dataclasses and type hints, making it easier for developers to work with ASN.1 structures.

The development plan involves building basic support for ASN.1 types, integrating the new API into PyCA Cryptography, and releasing it alongside future versions of the library. The initiative is funded by Alpha-Omega and aims to enhance the Python ecosystem's capabilities in cryptography and security.

Summary of Apollo 13 Story

Apollo 13 was a space mission launched on April 11, 1970, aiming to land on the Moon. However, two days into the mission, an oxygen tank exploded, leaving the astronauts—Jim Lovell, Jack Swigert, and Fred Haise—stranded in space without enough oxygen, water, or electricity. They had to move to the lunar module, which had some oxygen, but not enough to sustain all three astronauts for the duration of their journey back to Earth.

One critical problem was the rising carbon dioxide levels in the lunar module. The carbon dioxide absorbers were designed for two astronauts, but now there were three, leading to a risk of suffocation. The absorbers used in the command module had square containers, while those in the lunar module were circular, making them incompatible.

Ground control engineers quickly devised a plan to modify the square absorbers for use in the lunar module. They instructed the astronauts to create a makeshift device using materials available in the spacecraft. This involved connecting a square absorber to the lunar module's system with duct tape, cardboard, and hoses. This improvised solution successfully reduced carbon dioxide levels, allowing the astronauts to breathe safely.

After a tense journey, the astronauts returned to Earth, where the command module safely splashed down in the ocean. They were rescued and returned home, grateful to have survived against the odds. The story highlights the importance of teamwork, ingenuity, and problem-solving in a crisis.

A team of scientists, including vision expert Austin Roorda, claims to have discovered a new color called "olo," which can only be experienced through laser stimulation of the retina. In an experiment, they fired laser pulses into their eyes, specifically targeting M cones in the retina, which are usually not activated by natural light. They describe olo as a rich, saturated color that appears blue-green, but it cannot be fully conveyed through traditional displays.

The researchers mapped the retina to stimulate M cones alone, resulting in a color perception that exceeds normal human vision. While they provided an image of a turquoise square as a reference for olo, they emphasized that the actual experience of the color is much more vivid.

Some experts have questioned the significance of this discovery, suggesting it is just a more intense shade of green. The researchers believe their work could help advance understanding of visual perception and may have implications for studying color blindness and vision-related diseases. However, they noted that olo is not likely to be available for public experience through current technology, like smartphones or VR headsets.

Many foreign students in the US are experiencing anxiety due to recent detentions and visa revocations linked to pro-Palestinian protests on college campuses. Agents have been seen detaining students without criminal charges, and reports indicate that over 1,000 students have had their visas revoked. The Trump administration claims that visas are a privilege that can be revoked for various reasons, including political speech.

Students are feeling targeted, especially those who have spoken out about the war in Gaza. Some are now carrying cards listing their constitutional rights and are afraid to leave their homes. The government argues that these actions are necessary to address concerns about safety for Jewish students and to counter activities that threaten US interests.

Civil liberties groups have criticized these detentions as violations of rights, while students deny any connections to terrorist organizations like Hamas. The atmosphere on campuses is tense, with students fearing arrest simply for expressing their views. Some universities are also facing institutional threats, like funding freezes, if they do not comply with government demands regarding student visas.

Summary of Constraint System Work (Fall 2023)

At the start of phase 2, the team faced challenges with implementing a constraint system, which is crucial for creating realistic mechanical models and enabling dynamic interactions between objects. Although constraints have potential, they are often unreliable, leading to issues like:

1. Floaty-ness: Changes in one parameter can cause other parameters to behave unnaturally.
2. Blow-ups: Adjusting parts of the system can lead to instability, causing parts to collapse or explode.
3. Poor performance: Slow calculations or excessive recalculations occur when adding or removing constraints.

Initially optimistic, Alex made progress by reducing the number of variables the solver needed to handle. He achieved this by using equality constraints, which allowed for a more efficient solving process. For example, an angle constraint could manage two variables (degrees and radians) as one, improving accuracy and stability.

A key improvement was the introduction of a system that recognizes when conflicting constraints are added. Instead of creating instability, it maintains a single variable for the angle while allowing users to add additional constraints without risk.

The team also implemented "clustering," which organizes constraints into groups that can be solved separately. This not only improves performance but also opens the door for parallel processing in larger projects.

The flexibility of the constraint system allows the integration of various solvers, leading to better results. They experimented with different solvers, achieving improved convergence. Future plans include testing a new solver that uses advanced techniques for better performance.

Lastly, they improved how values are represented in the system, shifting from Cartesian to polar coordinates for better relationships between positions.

Summary: Synology's Hard Drive Locking Controversy

Synology is facing criticism for its decision to lock its NAS (Network Attached Storage) units to only its branded hard drives in the new 2025 Plus models. This change limits users' choices and could negatively impact their data security and recovery options. Users will lose access to important features like volume deduplication and firmware updates for non-Synology drives, making it harder to manage their storage effectively.

The article argues that this move seems to be a way for Synology to increase profits rather than provide better service to customers. The locked drives have lower capacity options compared to competitors, which could hinder users' ability to scale their storage needs. Additionally, the reliance on Synology for drive replacements raises concerns about future availability, especially if the company faces financial difficulties.

Overall, the writer expresses disappointment in Synology's outdated hardware and the restrictive practices, making it difficult to recommend their products over other options in the market.

OpenAI has released two new AI models, o3 and o4-mini, which are advanced but have a significant issue: they hallucinate, or make up information, more than some of OpenAI's older models. Hallucinations are a major challenge in AI, and while past models had shown improvement in reducing these errors, o3 and o4-mini have not followed this trend.

Internal tests revealed that o3 hallucinated 33% of the time on a specific knowledge test, which is double the rate of earlier models. O4-mini performed even worse, with a 48% hallucination rate. Third-party tests also showed that o3 sometimes incorrectly claimed to have performed actions, like running code on a computer, which it cannot do.

Experts suggest that the methods used to improve these reasoning models might be causing more hallucinations. While these models perform well in certain tasks, their high error rates could make them less appealing for businesses that require accuracy, such as law firms.

One potential solution to reduce hallucinations is to incorporate web search capabilities, which could help improve accuracy. OpenAI acknowledges that addressing hallucinations is a key area of ongoing research and is working to enhance the reliability of its models.

Summary:

Art viewing is gaining recognition for its potential benefits to well-being, but research in this area is fragmented. A systematic review was conducted to gather evidence on how art viewing impacts well-being, examining 38 studies with over 6,800 participants. This review explored various art viewing experiences, study designs, and the outcomes observed.

Key findings include:

1. Diverse Experiences: Art viewing occurs in numerous settings (like museums and online), with different activities and schedules, leading to various well-being outcomes.

2. Mechanisms of Impact: The review identified several mechanisms through which art viewing may enhance well-being, including emotional, cognitive, social, and resilience-building aspects. However, strong evidence mainly supports its effects on eudemonic well-being (a sense of meaning and purpose), with less support for other outcomes.

3. Research Gaps: The study highlights the need for more rigorous methodologies and a clearer understanding of what specific elements of art viewing (like context and duration) contribute to its positive effects.

4. New Guidelines: To facilitate future research, the authors introduced the Receptive Art Activity Research Reporting Guidelines (RAARR), aimed at standardizing how art interventions are described in studies.

In summary, while there is evidence that viewing art can improve well-being, more structured research is necessary to fully understand how and when these benefits occur.

The article discusses the author's journey with the programming language Objective-C, which he initially found charming and powerful. Objective-C was developed in the 1980s by combining object-oriented programming with C language syntax. Although it was verbose and complex, the author appreciated its expressiveness when he learned it during college.

However, as he worked professionally with Objective-C, he grew frustrated with its lengthy syntax and the difficulties it created in managing large codebases. The language’s verbosity became burdensome, leading to confusion and bugs in the code.

In 2014, Apple introduced Swift, a new programming language that addressed many of the issues developers had with Objective-C, favoring concise and clear code. Despite his fondness for Objective-C, the author recognized the need for change and felt that the pursuit of the perfect programming language, akin to Gottfried Leibniz’s dream of a universal language, is an ongoing journey for programmers. Ultimately, he decided to leave software engineering for other pursuits.

We introduce a new method for creating neural Signed Distance Fields (SDF) from point clouds that don't have a specific orientation. Instead of using the usual eikonal equation, we apply the heat method, which is a common technique for calculating distances on surfaces. Our approach involves two main steps using neural networks:

1. We first estimate the gradients of the unsigned distance field by applying a small amount of heat flow to the point cloud data.
2. Then, we use this estimate to calculate the neural SDF.

We confirm that the problems we solve are well-defined and, through tests, we show that our method achieves excellent surface reconstruction and reliable SDF gradients. Additionally, we demonstrate that it can accurately solve a partial differential equation related to the zero-level set.

Summary:

In an article dated April 6, 2025, Molson Hart argues that the new tariffs on imports, announced by the president, will not successfully bring manufacturing back to the U.S. Instead, they may harm the economy. Hart, who has extensive experience in manufacturing, outlines 14 reasons why these tariffs are ineffective:

1. Tariffs are too low: Even with tariffs, manufacturing in the U.S. remains more expensive than in countries like China.
2. Weak supply chains: The U.S. lacks a robust industrial supply chain, making it difficult to source necessary components locally.
3. Lack of manufacturing know-how: The U.S. has lost the expertise required to produce many essential components.
4. Labor costs: American labor is more expensive and often less reliable compared to Chinese workers, who have a strong work ethic and skills.
5. Inadequate infrastructure: The U.S. needs significant improvements in energy and transportation infrastructure to support manufacturing.
6. Long setup times: Building factories in the U.S. takes years, delaying any potential benefits from tariffs.
7. Uncertain tariff policies: Frequent changes in tariffs create an unstable business environment, discouraging investment.
8. Public perception: Many Americans prefer jobs in sectors like technology rather than manufacturing, which is often seen as undesirable work.
9. Lack of available skilled labor: There aren’t enough workers with the necessary skills to fill manufacturing jobs.
10. Automation: Automation is not a silver bullet; China is advancing rapidly in this area and is already ahead.
11. Litigious environment: The U.S. has a high risk of lawsuits, which can deter manufacturing investment.
12. Uneven enforcement of tariffs: U.S. companies face stricter repercussions for tariff violations than foreign companies, creating an unfair playing field.
13. Misstructuring of tariffs: Tariffs on both finished goods and components hinder domestic production.
14. Globalization continues: The policies may push manufacturing to countries like Vietnam instead of returning to the U.S.

Hart concludes that without essential reforms—like improving labor conditions, infrastructure, and manufacturing know-how—the U.S. will struggle to regain its manufacturing strength. He emphasizes that a systematic, gradual approach is needed to encourage domestic production rather than abrupt and poorly considered tariff policies.

The text discusses measuring a value (P) using two unreliable sensors, A and B. Sensor A provides a noisy measurement, while sensor B gives either the correct value or random noise with equal likelihood.

Key points include:

1. Error Analysis: Sensor A's error can be large, while sensor B's error is smaller but never exactly zero. Combining both sensors reduces error compared to using them individually.

2. Optimal Weighting: By adjusting the weights of sensors A and B, the best mean error occurs at a weight of about 0.58 for sensor A, improving precision over a 50-50 mix.

3. Using Differences: A strategy is proposed where if the difference between A and B is small (below a certain threshold), sensor B's reading is trusted; if the difference is large, sensor A is preferred. A mixed approach is used for values in between.

4. Improved Accuracy: This method yields a better mean error of about 0.1163, which is an improvement over the simple linear mix, suggesting the potential for more complex mixing strategies.

The author seeks further ideas on improving these estimates.

A 1,700-year-old egg found in England has left scientists puzzled because it remains completely intact and full of liquid. Discovered in a site called Berryfields, which was used by Romans for rituals, the egg is the oldest unintentionally preserved avian egg ever found.

Researchers believe the egg’s preservation is due to anaerobic conditions in the waterlogged soil, preventing oxygen from causing decomposition. While the egg was found among broken shells, its intact state is unusual and may provide insights into Roman culture and rituals related to fertility.

Scientists plan to carefully extract the liquid inside the egg for analysis, including DNA testing to identify the species that laid it. They suspect it might be from a chicken, which held significance in Roman rituals. The egg will eventually be displayed at London’s Natural History Museum after further research.

In 2019, Gmail product manager Aakash Shaney noted that email had not changed much, but Google introduced AMP for email to make messages more interactive and up-to-date. This allowed users to perform tasks like booking flights directly from their inboxes. However, many developers questioned the need for these changes and expressed concerns about the potential loss of control over their content.

AMP (Accelerated Mobile Pages) initially aimed to improve mobile web performance, but it faced criticism for creating separate experiences for mobile and desktop users. As Google pushed for AMP adoption, some web developers viewed it as a threat to the open web, leading to antitrust lawsuits against Google regarding its advertising practices.

When AMP was introduced to email, it required developers to create multiple versions of their emails (AMP, HTML, and plain text), which increased the complexity and effort needed to send messages. Despite some initial interest, many email services did not fully support AMP, leading to doubts about its longevity.

In 2021, Google quietly scaled back its support for AMP, indicating a shift away from the project. Although Google still uses AMP for some features within Gmail, the broader AMP for Email initiative has not been updated, and many developers have moved on to using standard HTML for email interactivity.

Overall, email is expected to evolve slowly while maintaining its core characteristics, such as reliability and permanence. The desire for interactivity does not need to compromise the fundamental nature of email, which remains a stable form of communication despite technological advancements.

The article discusses a study that examines how adipose (fat) tissue retains an "epigenetic memory" of obesity even after significant weight loss. Researchers used advanced sequencing techniques to analyze fat tissue from both humans and mice. They found that changes in gene expression related to obesity persist in fat cells even after weight loss, indicating that the body may have a lasting memory of its previous obese state.

Key findings include:

• Weight loss is difficult to maintain because the body seems to remember its obesity state, which can lead to weight regain (the "yo-yo" effect).
• Mouse studies showed that fat cells have permanent changes in their epigenetic makeup due to obesity, affecting their function and response to high-fat diets.
• The study identified that these changes in fat tissue can help explain why some individuals struggle to keep weight off after losing it.

Overall, the research suggests that targeting these lasting epigenetic changes could help improve long-term weight management and health outcomes for people dealing with obesity.
