The text discusses a peculiar hardware bug in the Raspberry Pi 2, known as the "Xenon Death Flash," which caused the device to crash when exposed to xenon camera flashes. This issue was first discovered by Peter Onion in 2015, who shared his findings with the Raspberry Pi community. Users quickly began investigating, revealing that the problem stemmed from a specific chip (U16) that was sensitive to intense light due to its design.

The bug was linked to the technology used in modern semiconductor packaging, which prioritizes small size over protection, making these chips more vulnerable to optical interference. Similar issues had occurred in the past, highlighting a broader risk in electronic design as devices become smaller and more complex.

To address the problem, users initially covered the sensitive chip with materials like Blu-Tack to block light. The Raspberry Pi Foundation later released a hardware update that redesigned the power management system to eliminate the vulnerability entirely.

This incident raised awareness about the need for comprehensive testing in electronics and showcased the effectiveness of community problem-solving. It serves as a reminder that as technology advances, unexpected vulnerabilities can arise, and collaboration can help tackle these challenges.

Zaha Hadid Architects has started construction on their first adobe project, the Asaan Museum, in Riyadh. This marks a significant development in architecture.

Summary of DumPy Proposal:

DumPy is a proposed alternative to NumPy designed to simplify array programming and reduce cognitive load while maintaining performance, especially on GPUs. The main ideas behind DumPy are:

1. Minimize Complexity: The goal is to reduce unnecessary thinking when programming with arrays. The author believes that NumPy's handling of high-dimensional arrays introduces too much complexity, requiring users to constantly consider array shapes and function behaviors.

2. Loop Syntax: DumPy suggests reintroducing the familiar loop syntax to deal with higher dimensions without actually executing loops. Instead, it would compile this syntax into efficient vectorized operations.

3. Simplified Indexing and Operations: DumPy will limit indexing and operations to avoid confusion. For example, broadcasting and complex indexing rules in NumPy will be removed. You can only perform operations on arrays of the same shape or when one is a scalar.

4. Named Dimensions: While DumPy uses named dimensions for clarity, it avoids the complications that arise from having permanent names within the arrays, which can confuse linear algebra operations.

5. Practical Examples: The author illustrates how DumPy allows users to perform array operations easily compared to NumPy and JAX, which often require more complex code and additional consideration of dimensions.

6. Performance Testing: The author claims DumPy performs comparably to loops in terms of speed and ease of use, suggesting that simplifying the syntax and operations can lead to more efficient coding practices.

In essence, DumPy aims to make array programming as intuitive as possible while leveraging the speed of GPUs, with a focus on reducing the mental overhead associated with complex array manipulations.

Summary of "Caesar's Last Breath"

On May 23, 2025, it was revealed that with each breath we take, we inhale about one molecule from Julius Caesar's last breath. This concept highlights how all the breaths taken by people throughout history, like Socrates and Einstein, are shared in the air we breathe.

The text explains the method of Fermi estimation, a way to make rough calculations using basic numbers. To find out how many molecules from Caesar’s breath we inhale, we need to estimate:

1. The volume of Earth's atmosphere: It's approximately 5 x 10^18 m³.
2. The volume of a breath: About 5 x 10^-4 m³.

By calculating the fraction of the atmosphere that consists of Caesar's breath and multiplying that by the number of molecules in a breath (about 10^22), we find that we inhale roughly one molecule from him with each breath.

This estimation process demonstrates the power of simple calculations and encourages others to engage in Fermi estimation for fun and learning.

Summary: LLM Judges Are Unreliable

Large Language Models (LLMs) are increasingly used for decision-making in sensitive areas like hiring and law. However, their reliability is questionable due to various biases in how they interpret prompts and tasks. Key issues include:

1. Prompt Engineering: Engineers often create prompts based on anecdotal practices rather than solid testing, leading to unpredictable outputs.

2. Positional Preferences: LLMs show a tendency to favor certain responses based on their order in prompts, similar to human cognitive biases.

3. Scoring Inconsistencies: The order in which criteria are presented can significantly affect scores. For example, an item scored last tends to receive lower ratings.

4. Scale Interpretation Bias: LLMs often misinterpret scoring systems, especially when higher scores should indicate negative traits, leading to inaccurate assessments.

5. Classification Sensitivity: LLMs are highly sensitive to changes in prompt wording and structure, causing instability in their classifications.

6. Model Variability: Different LLMs exhibit different biases, meaning it's essential to select and test models carefully for specific tasks.

To improve the reliability of LLMs in judgment tasks, the author suggests several strategies, such as using neutral labels, varying the order of items, rigorously testing prompts, and diversifying the model portfolio. It's crucial to understand the biases inherent in LLMs, especially when used in high-stakes areas, as these biases can have significant consequences.

Researchers are encouraged to systematically test and quantify biases in LLMs to ensure more reliable outputs.

The metre, a unit of measurement, was established during the French Revolution in the late 1700s. It was first defined as one ten-millionth of the distance from the North Pole to the equator, calculated by astronomers and represented by a platinum bar. The definition of the metre has evolved over time, leading to the creation of the metric system.

On May 20, 1875, representatives from 17 countries signed the Metre Convention in Paris, which aimed to standardize measurements worldwide. This led to the establishment of the International Bureau of Weights and Measures.

In 1960, the metre was redefined based on the wavelength of light from krypton gas. Later, in 1983, it was defined as the distance light travels in a vacuum in 1/299,792,458 of a second, utilizing atomic clocks for precision.

Despite the metric system's adoption, many countries, including Australia and the United States, have been slow to fully embrace it. For instance, Australia took over 20 years after signing the treaty to implement the metric system officially. Today, while the metric system is recognized, some imperial units are still commonly used, causing inconsistencies, especially in cooking measurements.

We present a method for creating Diophantine equations with limited complexity using Isabelle/HOL, based on our research in number theory. Hilbert's Tenth Problem, which asks if there is a general way to determine if a Diophantine equation has a solution, was shown to have no solution by Yuri Matiyasevich. However, this issue is still open when looking at rational numbers or equations with limited complexity, defined by the number of variables (ν) and the degree (δ). If all Diophantine sets can be represented within these limits, we call that pair universal, and it means the equations are undecidable.

In our work, we provide a formal verification of the construction needed to establish this universal pair, marking a significant addition to the existing Isabelle AFP on multivariate polynomials. We also formalize concepts from a number theory textbook and classical theories on Diophantine equations in Isabelle. Additionally, we create tools for handling complex definitions of multivariate polynomials more effectively. Our mathematical draft has been developed alongside our research and has benefited from the use of theorem proving. We emphasize the value of the collaboration between mathematicians and computers, which is rare but highly effective.

Summary: Autopsy of an LHC Beam Dump

CERN recently conducted its first autopsy on a radioactive beam dump from the Large Hadron Collider (LHC). This investigation aimed to understand how materials behave when exposed to high-energy beams. The external beam dumps had to be replaced after showing signs of wear, including nitrogen leaks.

To explore the cause of these leaks, an endoscopy revealed cracks in the graphite components of the dump. Consequently, an autopsy was planned to inspect the dump's main parts—high-density, low-density, and extruded graphite. Due to the dump's radioactivity, cutting into it was challenging. Initially, attempts to cut through its tough stainless-steel housing were unsuccessful.

Eventually, CERN teams developed remote cutting techniques using an automated circular saw and a robotic arm. They successfully made the necessary cuts in a specially designed radiation airlock. The autopsy showed that while the extruded graphite discs were cracked, the low-density graphite was in good condition.

The findings confirmed that low-density and high-density graphite could be used for the LHC's next phase, Run 3, but extruded graphite should not be used in future designs. Ongoing studies are testing new materials for future beam dumps. Overall, the modifications made to the existing dumps are expected to enhance their durability for the increased energy levels planned for Run 3.

Summary of "Writing A Job Runner (In Elixir) (Again) (10 years later)"

This article updates a previous post about creating a job runner in Elixir, ten years later. The original code remains largely the same, but the explanation is clearer and more detailed. The author aims to share this work for both Elixir beginners and seasoned developers, encouraging them to explore job processing.

Key Points:

1. Job Processing Basics: Most applications need to perform background tasks, or "jobs," which may require using separate processing to avoid blocking the main application.

2. Job Runner Architecture: A job runner is essentially software that runs other code. In Elixir, this is facilitated by GenStage, a library that enables a demand-driven architecture where consumers request work from producers, ensuring efficient processing.

3. GenStage Overview:

   • Producers generate tasks (jobs) and respond to consumer requests.
   • Consumers process these tasks and request more as they finish.
   • This model provides an elegant solution to managing job flow without overwhelming any part of the system.

4. Elixir Advantages: Elixir’s process model, based on the BEAM VM, allows for lightweight, isolated processes that can recover from failures without affecting others. This makes it ideal for building reliable job processing systems.

5. Components of the Job Runner:

   • Producers fetch jobs from a database.
   • Consumers execute the jobs and handle failures by retrying or logging errors.
   • Jobs are stored in a database with their statuses (queued, running, completed, failed) allowing for persistence and tracking.

6. Building the Job Runner:

   • The article outlines steps for creating a Phoenix application using GenStage.
   • It details how to set up producers and consumers, handle job fetching and execution, and implement error handling.

7. Advanced Features:

   • Techniques for scaling, such as adding more consumers for higher throughput and handling job retries.
   • Suggestions for structuring the code for production use, including more sophisticated error handling and observability.

8. Final Product: The job runner is designed to be robust, resilient, and capable of processing jobs efficiently, utilizing Elixir's strengths in concurrency and fault tolerance.

This update serves as a practical guide for developers wanting to understand job processing in Elixir using modern practices.

Recent results from large reasoning models have been seen as proof of the effectiveness of Chain of Thought (CoT) reasoning. This paper critically examines this view by looking at how the meaning of intermediate tokens, often seen as "thoughts," affects model performance. The authors train transformer models using formally verified reasoning steps, comparing these to a formal problem-solving method (A* search).

They evaluate both the accuracy of the final solutions and the correctness of the intermediate reasoning steps. Interestingly, even when models are trained with correct reasoning steps, they still produce incorrect intermediate traces while achieving correct solutions. Furthermore, when models are trained on noisy or unrelated reasoning data, their performance remains similar to those trained on correct data, sometimes even improving and showing better generalization on new tasks.

These findings suggest that the connection between intermediate reasoning steps and final solution accuracy is weak, challenging the idea that these "Chains of Thought" reliably indicate reasoning processes. The authors caution against viewing these outputs as evidence of human-like thinking in language models.

The article discusses how to design type inference in programming languages to generate clear and helpful error messages when type errors occur. Many existing languages produce confusing error messages due to design choices that prioritize other goals over clarity.

The author, who created an experimental language called PolySubML, emphasizes that type inference does not inherently lead to poor error messages. Instead, it is often the language's design that causes problems. Here are the key points covered:

1. Avoid Guessing and Backtracking: Compilers should not attempt to guess types or backtrack when checking for errors. This can lead to longer and less useful error messages. Instead, compilers should provide a clear chain of reasoning for why a type is invalid.

2. Contextual Errors: Error messages should highlight the specific context of the error. For example, when a type mismatch occurs, the message should indicate where the conflicting types originated, rather than making assumptions about the expected types.

3. User Clarification: Instead of presenting long error messages, compilers should ask users for clarification at specific points in their code. This can help narrow down the source of the error without overwhelming the user with information.

4. Explicit Type Annotations: Users should be able to add explicit type annotations in their code to help identify and resolve type conflicts. The language should allow for easy expression of all types that can be inferred.

5. Avoid Complex Static Inference: The design should not include complex static type inference within the runtime execution model, as this can lead to unexpected behaviors and confusing error messages.

In conclusion, the article argues that with thoughtful design, it is possible to achieve high-quality type error messages in languages that use type inference, leading to a better user experience during development.

Summary of "The Curious Case of the Pygmy Nuthatch"

The article explores a significant mistake in the film "Charlie's Angels" regarding the depiction of a bird, specifically the pygmy nuthatch. The author, Forrest Wickman, shares his journey of investigating this error, which has puzzled bird enthusiasts for years.

During the pandemic, Wickman developed a passion for bird-watching and began noticing inaccuracies in films that featured birds. In "Charlie's Angels," a character incorrectly identifies a Venezuelan troupial as a pygmy nuthatch, claiming it only lives in Carmel, California. This is incorrect as the bird is not only larger and differently colored but also not native to that area.

Wickman delves into the film's production, revealing that the script underwent numerous rewrites by different writers, which led to the introduction of the pygmy nuthatch name for comedic effect. However, when it came time to film, the production team opted for visually striking birds that fit the scene's tropical setting, leading to the use of the Venezuelan troupial instead.

The bird's song heard in the film was also a mismatch: it turned out to be a recording of a thick-billed fox sparrow, manipulated to fit the scene, which further added to the confusion among birders.

In the end, Wickman concludes that the errors stemmed from the chaotic nature of filmmaking, where many decisions are made under pressure. While the film did not accurately portray the bird, the choices made by the filmmakers were driven by a desire to create an entertaining product. The investigation highlights the complexities of filmmaking, where creativity sometimes leads to bizarre outcomes.

Summary:

Lorin Hochstein critiques the traditional Root Cause Analysis (RCA) approach to investigating incidents, arguing that it oversimplifies complex system failures. He emphasizes that RCA focuses on identifying a linear chain of causes (root, underlying, and immediate) to prevent future incidents, but this model is flawed.

Hochstein appreciates some aspects of the UK Health and Safety Executive's guide on RCA, such as acknowledging multiple causes and the importance of investigating near misses. However, he believes that RCA's causal model fails to capture the complexity of interactions in systems.

Instead, he proposes the Resilience Engineering (RE) model, which views incidents as results of unpredictable interactions between system components rather than a series of causes. The RE model focuses on how systems adapt to faults and maintain functionality despite existing issues. It encourages organizations to develop their adaptive capacity rather than solely eliminating root causes, recognizing that latent failures are always present, leading to different incidents over time.

In summary, Hochstein advocates for a shift from RCA to RE to foster better understanding and management of complex systems.

Summary: 'Turbocharged' Mitochondria Power Birds’ Epic Migratory Journeys

Researchers are exploring how birds manage long migrations, such as the white-crowned sparrow's 2,600-mile trip from Mexico to Alaska and the Arctic tern's 10,000-mile journey to Antarctica. These birds undergo significant physiological changes, including increased body weight and enlarged hearts, to support their endurance during migration.

A key finding from recent studies is the role of mitochondria, the cell's energy producers. During migration, birds experience changes in the quantity, shape, and efficiency of their mitochondria, which help them generate more energy for sustained flight. Unlike humans, birds can adapt their mitochondrial performance quickly in response to environmental cues, like changing light conditions in spring, without needing prolonged training.

Two independent research teams found that migratory birds have "turbocharged" mitochondria that are more numerous and efficient compared to non-migratory birds. This enhanced mitochondrial function allows birds to fly for many hours without food.

Additionally, the studies suggest that while increased mitochondrial activity provides energy, it also produces harmful molecules called reactive oxygen species. Birds may mitigate this risk through a diet rich in antioxidants.

These findings shed light on the intricate adaptations that enable birds to undertake remarkable migratory feats and hint at the broader implications for understanding energy use in both birds and humans.

The text discusses the concept of "Vibe Coding," a trend in software development where users rely on AI code assistants to generate code based on brief problem descriptions, rather than engaging deeply with software architecture or programming principles.

1. Agentic AI and Vibe Coding: "Agentic AI" refers to AI systems that perform tasks autonomously, while "Vibe Coding" emphasizes quick code generation without thorough understanding or planning.

2. Narrative Power: The term "Vibe Coding" promotes ideas of democratizing technology and empowering individuals, but the author argues these narratives are misleading and ignore the complexities of software development.

3. Misunderstanding Software: Many people have a superficial understanding of how software is created. Effective software development requires careful analysis of requirements, user needs, and thoughtful architecture, not just coding.

4. Risks of Vibe Coding: Relying on AI for coding can lead to poor-quality software that lacks proper structure and understanding, which can create long-term issues and dependencies on less effective tools.

5. Devaluation of Skills: The trend diminishes the value of learning and expertise, suggesting that quick fixes replace the journey of personal growth and skill acquisition in coding.

6. Cynicism vs. Empowerment: The author argues that while vibe coding appears to empower individuals by providing tools, it often leads to inadequate solutions and reinforces existing inequalities, especially for marginalized groups.

7. External Consequences: Poorly developed software can negatively impact users and systems, contributing to a broader decline in the quality of digital products and services.

8. Final Thoughts: The emphasis on output without a commitment to quality and understanding is seen as disrespectful and detrimental to both individuals and society. The author calls for a more thoughtful approach to software development that prioritizes skill development and meaningful engagement with the work.

Overall, the text critiques the superficial allure of "Vibe Coding" while highlighting the importance of expertise and thoughtful processes in software development.

Summary: When a Team is Too Big

Alex Ewerlöf explores the challenges of large teams and advocates for a more effective approach to teamwork. Key points include:

1. Team Size: Large teams can lead to inefficiencies, misunderstandings, and communication issues. A team that is too big often struggles with coordination, resulting in missed tasks and unclear responsibilities.

2. Generalists vs. Specialists: Generalist teams tend to be more productive and resilient because they reduce internal dependencies and bottlenecks. In contrast, specialists can create complications due to their narrow focus, leading to communication breakdowns and delays.

3. Standup Meetings: Initial standup meetings in a large team were ineffective, often causing boredom and lack of engagement. Switching to asynchronous updates helped reduce disruption but also missed the valuable dialogues that standups are meant to foster.

4. Task Forces: Attempts to split the team into focused task forces by specialization initially seemed promising but revealed dependencies between groups, indicating that collaboration was still necessary.

5. The Shift to Generalism: The ultimate solution was to transition the team from specialists to generalists. This allowed for better ownership, collaboration, and knowledge sharing. The generalist model encouraged team members to learn multiple skills, reducing handover issues.

6. Challenges of Generalism: While generalism improved productivity, it also led to burnout and a lack of depth in specialized skills. Balancing workload and ensuring sustainable practices are important.

7. Culture of Experimentation: The team's success stemmed from a culture of continuous improvement and experimentation, allowing them to adapt their workflow effectively.

In conclusion, Ewerlöf emphasizes that the root of teamwork issues often lies in a lack of shared goals and communication. A willingness to experiment and adapt is crucial for any team's success.

The author reflects on a fractal they created in middle school, which they've kept on their wall for 12 years. They call it "the wallflower" and describe how it was drawn by repeatedly tiling squares in different orientations. Over time, the author learned more about math and discovered that their fractal is similar to other known fractals.

They explain two methods for generating the fractal: one involves manual placement of shapes, while the other uses an L-System—a set of rules for drawing based on turns. Initially, the author thought both methods produced the same result, but later discovered differences, particularly in how the shapes were arranged around the center.

The text explores mathematical concepts like cardinality, pairing functions, and how to label the squares in a structured way. The author notices a connection between the fractal's growth and powers of 5, which leads them to develop a unique number system based on vectors and matrices.

They also delve into the idea of extending the fractal into higher dimensions and consider the challenges involved. Ultimately, the author reflects on their journey of rediscovery and the beauty of math, expressing hope that their exploration inspires others to find joy in similar pursuits.

Google recently announced Gemini Diffusion, their first language model (LLM) that uses diffusion techniques instead of traditional transformers.

Key points about Gemini Diffusion:

1. How It Works: Unlike standard language models that generate text one word at a time (which can be slow), diffusion models generate text by refining noise in a step-by-step process. This allows them to correct errors and produce high-quality outputs more quickly.

2. Speed: The model is notably fast. For example, it can produce text at a rate of 857 tokens per second. In a test, it created a simulated chat app in just a few seconds.

3. Comparison: While Gemini Diffusion is fast, it is compared to other tools like Cerebras Coder, which runs at about 2,000 tokens per second. Google claims it performs at "5x the speed" of their previous model, Gemini 2.0 Flash-Lite.

4. Clarification on Technology: There was some confusion about diffusion models. They do not completely replace transformers; instead, they modify how outputs are generated, often using a transformer structure but without the usual sequential token generation.

5. Training Process: The model is trained to predict masked tokens in a sentence, gradually reducing the number of masked tokens until it can generate full sequences of text.

Overall, Gemini Diffusion aims to combine the efficiency of diffusion models with the capabilities of existing language models, enhancing both speed and output quality.

Creating a distributed version of Postgres is challenging but not new. There are various approaches, such as:

• Citus: An open-source extension that requires manual setup.
• CockroachDB: Easier to integrate but not open-source and not a true Postgres.
• Neon: A true Postgres extension with interesting features, but not fully distributed.

None of these options met the author's needs, so they created pgfdb, an experimental open-source extension that makes Postgres work on top of FoundationDB. This allows it to maintain full compatibility with Postgres while gaining the scalability and reliability of FoundationDB.

pgfdb utilizes Postgres features to replace its standard storage and transaction systems, adapting to FoundationDB's capabilities. It's still in the experimental stage, and its performance is uncertain, but the author is open to discussions about it.

The text appears to be a simple login interface for an institutional account. It includes options to log in and mentions accessibility features.

The text discusses a new protocol called Model Context Protocol (MCP) that connects language models (LLMs) with symbolic computer algebra systems. The main idea is that while LLMs can understand math problems, they struggle to solve them, whereas computer algebra systems are designed for accurate mathematical manipulation. MCP allows LLMs to use these systems effectively.

MCP functions like a standard interface that lets LLMs call external tools through a server. It runs locally, which raises security concerns since it allows LLMs to execute arbitrary code.

The author experimented with MCP to help LLMs handle complex math tasks, particularly tensor calculus, which they often get wrong. By using MCP, the LLM can delegate mathematical computations to specialized tools like SymPy, ensuring accurate results.

The process of setting up and debugging an MCP server can be challenging, with issues often arising from non-deterministic behavior. However, when it works, the integration can produce correct solutions to complex problems, as shown in an example involving the damped harmonic oscillator.

The author encourages others to try the code available on GitHub but warns about potential security risks involved in running these servers. Overall, MCP has the potential to enhance how LLMs interact with mathematical software, making complex computations more accessible.

The text discusses two main approaches to statistics: frequentism and Bayesianism, aimed at helping scientists understand their differences and practical applications.

Key Points:

1. Definitions of Probability:

   • Frequentism: Defines probability based on the frequency of events occurring in repeated experiments. It suggests that probabilities relate to the outcomes of many trials, not to fixed values.
   • Bayesianism: Expands the concept of probability to represent levels of certainty about events. It allows for the estimation of probabilities based on prior knowledge and data.

2. Philosophical Differences:

   • Frequentists focus on the long-term frequency of events, while Bayesians emphasize knowledge and belief about parameters.

3. Practical Application:

   • The text provides examples comparing how frequentist and Bayesian methods handle a simple statistical problem: estimating the true flux of light from a star based on observed photon counts.
   • Both approaches can yield similar estimates for simple problems, but may diverge significantly in more complex scenarios.

4. Methods:

   • Frequentist methods use maximum likelihood estimation to find the best estimate and confidence intervals.
   • Bayesian methods apply Bayes' theorem, using prior distributions and likelihoods to derive posterior distributions, often utilizing sampling techniques like Markov Chain Monte Carlo (MCMC) for complex models.

5. Conclusion:

   • While both approaches can lead to similar results in straightforward cases, they develop distinct methodologies and interpretations, especially as problems increase in complexity. The text encourages further exploration of these differences in future discussions.

In summary, the text serves as an introduction to the foundational differences between frequentist and Bayesian statistics, highlighting their implications for scientific data analysis.

Computing the eigendecomposition of a matrix can lead to errors due to floating-point arithmetic on computers, as noted by Wilkinson in 1965. This means that even if a real asymmetric matrix has repeated real eigenvalues, the computed solution might show complex eigenvalues instead.

Recently, some colleagues faced a reproducibility issue while running R code for simulations that generated samples from a multivariate normal distribution. Despite using set.seed() to control random number generation, they consistently received different results on different machines, which was far from what they expected. Their initial thoughts were that they had made an error in their code, or that the R function MASS::mvrnorm() was faulty.

After investigation, it became clear that the problem stemmed from floating-point arithmetic errors rather than their code or the R package. Floating-point operations can lead to tiny discrepancies in numerical calculations, which can produce significantly different results, especially in more complex scenarios like generating multivariate normal samples.

For example, two similar covariance matrices might appear identical but differ slightly due to these computational errors. When random samples are generated from these matrices, small differences can lead to vastly different outputs, even when the random number generator seed is the same. This highlights the complexities and unpredictability of numerical computations on computers, where tiny input variations can lead to large output discrepancies, especially in multivariate cases.

In summary, while set.seed() usually ensures reproducibility in R, floating-point arithmetic can disrupt this expectation, making it essential to understand the limitations of numerical methods.
