Over the past month, we investigated reports that Claude's performance had declined for some users. We identified three specific issues related to changes made to Claude Code, the Claude Agent SDK, and Claude Cowork, while confirming that the API remained unaffected. These issues have been resolved as of April 20.

1. Reasoning Effort Change: On March 4, we lowered Claude Code's default reasoning effort from high to medium to reduce latency. This change made the model seem less intelligent, leading us to revert to high reasoning effort on April 7 based on user feedback.

2. Memory Clearing Bug: On March 26, a bug in a change intended to clear old reasoning from idle sessions caused Claude to forget context during conversations, making it repetitive. This bug was fixed on April 10.

3. Verbosity Reduction: On April 16, we attempted to reduce output verbosity, but this negatively impacted coding quality. We reverted this change on April 20.

The combination of these changes led users to perceive overall degraded performance, although our internal tests did not initially show the same issues. From April 23, we are resetting usage limits for all subscribers to improve user experience.

Going forward, we will enhance our testing processes, implement stricter controls on system prompt changes, and ensure better internal use of public builds to catch issues earlier. We appreciate user feedback, which helped us identify and resolve these problems.

Arch Linux has introduced a bit-for-bit reproducible Docker image, which is now available under a new “repro” tag. This image ensures that users can create consistent builds, although it comes with a limitation: the pacman package manager is not usable without additional setup. Users need to generate the pacman keyring within the container before they can install or update packages by running specific commands.

The reproducibility of the image is confirmed through digest checks and comparisons of builds. Building the image in a deterministic way was challenging but used similar processes as the WSL image. Key adjustments were made to ensure consistency, such as normalizing timestamps and removing non-deterministic files.

The development team plans to enhance this effort by potentially setting up a system to periodically rebuild and verify the Docker image's reproducibility. This milestone is part of Arch Linux’s broader goal of achieving reproducible builds.

A gambling dispute in the 17th century led to the development of probability theory. The issue arose when a game of chance was interrupted, and players needed to fairly divide the pot based on their scores at that moment. This dilemma, known as the "problem of points," puzzled mathematicians for over 150 years.

Initially, mathematician Luca Pacioli suggested splitting the pot based on the points scored, but this method proved unfair in certain situations. Niccolò Tartaglia proposed a different approach, considering the players' chances of winning based on their current scores. However, both methods had flaws.

The breakthrough came when Blaise Pascal and Pierre de Fermat corresponded and developed new methods based on future possibilities. Fermat counted potential outcomes to determine a fair split, while Pascal devised a way to calculate expected values by working backward from future scenarios. Their work laid the foundation for modern probability theory and risk assessment, influencing fields like finance and insurance.

Today, expected value calculations help evaluate risks and make informed decisions, demonstrating the lasting impact of their mathematical discoveries.

The author has waited fourteen years to share insights about responsive images on the web. As a former leader in the web standards community, they played a crucial role in developing the responsive image markup that has since become a standard practice. While this markup improved web performance by allowing browsers to select appropriate image sizes based on user context, the author admits to frustrations with certain aspects of it, particularly the "sizes" attribute, which is complex and often difficult to use.

They explain that while responsive images are essential for optimizing image delivery, the "sizes" attribute presents challenges because browsers can't accurately determine how much space an image will take up on a page. This complexity often requires developers to create intricate and manual size descriptions for images, which is not user-friendly.

Recent updates to web standards have introduced an "auto" value for the sizes attribute, allowing browsers to automatically determine image sizes, making the process easier for developers. The author celebrates this change as a significant improvement, reducing the need for manual size specifications and streamlining image loading.

In summary, while the author acknowledges their role in the development of responsive images and the frustrations that come with it, they are optimistic about new advancements that simplify the process, ultimately benefiting web performance and user experience.

The article discusses the bacterial flagellar motor, a complex molecular machine that allows bacteria to move. After decades of research, scientists have finally understood how it works. This motor is like a tiny propeller that rotates rapidly to propel bacteria toward food sources. It can switch directions to help the bacteria navigate their environment.

The key to its operation is a physical phenomenon called the "proton motive force," which is the flow of protons (positively charged particles) into the cell. This force drives the motor's rotation and is essential for various biological processes. When bacteria sense changes in their surroundings, they adjust the motor's direction to either continue moving toward nutrients or to tumble and reorient themselves.

The discovery of the flagellar motor's mechanics involved advanced imaging techniques that revealed its structure and how its components interact. The motor's ability to switch directions is a sophisticated process, allowing bacteria to efficiently search for food. Overall, the flagellar motor exemplifies the incredible engineering achieved through billions of years of evolution in bacteria.

The text discusses the concept of "software brain," a mindset that views the world through the lens of algorithms and databases, significantly influenced by AI. While the tech industry is excited about AI's potential, many people, especially Gen Z, are increasingly critical of it, with surveys showing that a majority believe AI will cause more harm than good.

Despite the growing use of AI tools like ChatGPT, public sentiment is negative, driven by fears of job loss and increased surveillance. Tech leaders acknowledge the need to earn public trust and social permission for AI but have struggled to connect with regular people's concerns.

The author argues that this disconnect is rooted in the limitations of the "software brain," which oversimplifies complex human experiences into data-driven models. People do not want to conform their lives to fit into databases; they value the human aspects of life that cannot be easily automated or quantified. The push for AI integration into everyday life is seen as a threat to individuality and humanity, leading to negative feelings towards technology.

In conclusion, the author believes that the tech industry's focus on automation and data control overlooks the need for a more human-centered approach, resulting in a growing dislike for AI among the general public.

Summary:

AI-assisted coding tools have become common, but they often over-edit code when making fixes. This phenomenon, called "Over-Editing," occurs when a model rewrites more of the code than necessary, making it hard for reviewers to understand changes. For example, a model might rewrite an entire function when only a small fix is needed, complicating the review process.

To study Over-Editing, researchers created a dataset of corrupted code to analyze how much a model changes beyond the minimal fix required. They evaluated various models based on how well they preserved the original code while fixing bugs. Metrics included the Levenshtein Distance (measuring changes) and Cognitive Complexity (measuring readability).

Findings showed that many models, especially reasoning models, tended to over-edit. However, when explicitly instructed to keep edits minimal, models performed better. Training methods like reinforcement learning improved models' ability to make minimal edits without sacrificing their coding skills.

Overall, the study highlights that Over-Editing is a widespread issue in coding models, but it can be mitigated through better prompting and training techniques.

Matt Godbolt, known for Compiler Explorer, discussed why x86 compilers prefer the instruction xor eax, eax to set a register to zero. This instruction is more compact than mov eax, 0 because it doesn't require encoding a four-byte constant. Since x86 lacks a dedicated zero register, a method to zero a register is necessary.

Godbolt didn’t explain why xor is favored over other operations like sub eax, eax, which achieves the same result and has similar performance. However, xor eax, eax leaves the auxiliary flag (AF) undefined, while sub eax, eax clears it.

He speculates that xor gained popularity due to early compiler usage, leading others to view it as a clever choice. This trend influenced Intel to optimize the execution of both xor and sub when used in this way, effectively making them execute with zero cycles.

Despite Intel's support for both instructions, there are concerns that other CPU manufacturers may have only optimized for xor, solidifying its dominance. Once a slight advantage is established, it can lead to widespread adoption.

Additionally, Itanium architecture doesn’t benefit from the xor trick since it has a dedicated zero register, allowing for a straightforward zeroing operation.

A YouTuber named Dr. Semiconductor has taken on the challenge of building his own DRAM (dynamic random-access memory) in his backyard. This effort comes as memory prices have surged due to high demand from AI and data centers. In his videos, he documents the process of converting a shed into a cleanroom for semiconductor production and successfully creating small memory chips.

Dr. Semiconductor designed a simple 5x4 array of memory cells, built them on silicon, and tested their functionality. Although the chips worked, they had limitations, such as holding a charge for only 4 milliseconds compared to 64 milliseconds for commercial RAM. He acknowledged that while his homemade RAM can store data, it’s not yet suitable for running complex applications.

Despite this success, Dr. Semiconductor emphasizes that this is just a small-scale experiment and the broader memory shortage continues. He plans to combine more of his chips in future tests, but the creation of a cottage industry for homemade RAM is unlikely. The memory crisis is expected to persist, so consumers may need to brace for ongoing high prices.

The text discusses the concept of columnar storage in databases and how it relates to normalization.

1. Row vs. Column Storage: Data can be organized in two ways: row-oriented (where all columns of a row are stored together) and column-oriented (where data for each column is stored separately).

2. Advantages of Row Storage: It's easy to add new rows and retrieve entire rows quickly since all data is stored together. However, if you need to analyze specific data (like counting colors), you may have to read unnecessary information.

3. Advantages of Column Storage: This format allows efficient access to specific data, like colors, without reading irrelevant columns. However, it complicates data modification and row retrieval since you need to access multiple locations to reconstruct a full row.

4. Normalization Analogy: Columnar storage can be seen as a form of normalization, where data is split into separate tables based on attributes, linked by a primary key. This can streamline data analysis and query processing.

5. Conclusion: Understanding columnar storage as a normalization technique helps unify database operations like joins and projections, making it easier to think about data manipulation and query performance.

A recent study published on April 22, 2026, in the journal PLOS Climate reveals that 98% of environmental claims made by the world's largest meat and dairy companies are misleading and categorized as "greenwashing." The research, conducted by Maya Bach and Jennifer Jacquet from the University of Miami, analyzed 1,233 claims from 33 major companies in the animal agriculture sector, which significantly contributes to greenhouse gas emissions.

Key findings include:

• 68% of the claims were climate-related, focusing on greenhouse gas emissions.
• 38% of the claims were unverifiable future promises, such as achieving carbon neutrality by 2030.
• Only 29% of the claims had any supporting evidence, with just three backed by scientific research.
• The study shows a rise in net-zero commitments from these companies, but most rely on offsets rather than actual reductions in emissions.

The authors express concern that these misleading claims can confuse the public and hinder meaningful climate action. They emphasize that while the meat and dairy industries talk about climate change, many of their promises lack substance and evidence.

For more information, the article is available at PLOS Climate: Link.

The pricing of Large Language Models (LLMs) has become confusing, especially following Anthropic’s recent pricing changes. Their Head of Growth explained that a test went wrong, hinting at possible significant price increases for their code generation tools. Meanwhile, GitHub announced tighter usage limits for its Copilot product, which will degrade its service for users.

Sam Altman from OpenAI previously mentioned an AI bubble, noting that OpenAI is currently unprofitable despite substantial investments totaling over $290 billion. With pressure from investors for returns, companies may raise prices, which could drive users away.

Additionally, the rise of local LLMs running on personal hardware, like Apple’s M-series chips, is becoming more feasible. These local models are often more efficient and cost-effective than relying on energy-hungry data centers.

While LLMs can be beneficial tools, the current business model raises concerns. The future profitability of AI companies is uncertain, as they face challenges like potential price increases, decreased user interest, and competition from local computing solutions.

There are ongoing efforts to remove outdated kernel code, particularly from the networking subsystem, in response to an increase in security bug reports generated by large language models (LLMs). The specific code targeted for removal includes various Ethernet drivers, amateur radio protocols, and other legacy systems that have not been properly maintained.

The amateur radio protocols, such as AX.25, have been problematic due to numerous bug reports and a lack of volunteer support to manage these issues. Consequently, developers believe that removing these protocols from the main kernel is necessary to reduce maintenance burden and improve overall security.

There are discussions about whether these drivers should be maintained in the main Linux tree or moved to a separate location for those interested. Some argue that many of these protocols could operate in user space instead of the kernel, which would mitigate potential security risks.

Key points from the discussion include:

• The removal of unmaintained code can enhance security.
• Maintaining legacy drivers requires commitment from developers, which has been lacking.
• Some users suggest moving certain functionalities to user space to reduce kernel complexity.
• There's a call for better organization of outdated or unmaintained code, potentially in a separate module or directory.

Overall, the conversation reflects the challenges faced in balancing legacy support with the need for security and maintainability in modern software development.

2. Term Data Structure: A basic data structure called Term is defined, representing lambda expressions with symbols, lambdas, and applications.

3. Effectful Implementation: Instead of traditional recursion, Effekt uses a refunctionalized approach where data structures are handled through effects and handlers.

4. Pretty Printing: The pretty function is demonstrated to convert Term structures into string representations using a catamorphism.

5. Counting Constructors: An example function size counts the number of constructors in a lambda term without explicit recursion.

6. Free Variables: Another function retrieves all free variables in a term using a catamorphism.

7. Paramorphisms: The text explains how paramorphisms allow access to the original structure during processing, which can be useful for substitutions.

8. Anamorphisms: Anamorphisms unfold data structures from a seed, illustrated by generating natural numbers or constructing terms from de Bruijn indices.

9. Hylomorphisms: Hylomorphisms combine the processes of unfolding and folding, allowing for efficient term construction without unnecessary intermediate structures.

10. Interactive Learning: Readers are encouraged to experiment with the provided concepts and examples in an interactive environment.

Overall, the article showcases how to implement and utilize recursion schemes using effects in the Effekt programming language.

The author recently researched William James at Harvard, revealing that he was not only a renowned psychologist and philosopher but also a talented visual artist who initially aspired to be a painter. Despite none of his paintings surviving, his archives show he continued to draw throughout his life. James's artistic skills are linked to a broader cultural shift in the 19th century that integrated design with data visualization.

James, along with contemporaries like Francis Galton and W.E.B. Du Bois, significantly influenced the field of data visualization. They believed that creating visual representations of data was essential to the thinking process, rather than a mere afterthought. This perspective contrasts with modern AI design tools, which can automate design but may lack the unique human insight that comes from manual creation.

James contributed to early data visualization, including the first representation of a neural network and a visualization of the stream of consciousness in his work, "Principles of Psychology." Galton's work, which involved systematic data collection and visualization, was influential to James, although Galton's views on eugenics presented ethical concerns.

Du Bois, a student of James, creatively merged measurement with visualization to advocate for the achievements of Black Americans, producing striking charts for the 1900 Paris Exposition. The author argues that the personal touch in these early visualizations is lost with automated design tools, emphasizing the importance of hands-on creativity in research and thought processes.

The hyperbolic tangent function, ( tanh ), is a smooth S-shaped curve that maps real numbers to a range of (-1, 1). It's commonly used as an activation function in neural networks and for audio signal processing due to its ability to introduce non-linearity while keeping outputs within bounds. Both applications require fast calculations, as neural networks may need to compute ( tanh ) millions of times quickly, and audio processing often requires real-time performance.

To achieve faster approximations of ( tanh ), several methods exist:

1. Taylor Series: This method uses a polynomial expansion based on derivatives to approximate ( tanh ). By taking a few terms, we can get a quick estimate.

2. Padé Approximants: This approach uses the ratio of two polynomials to improve accuracy, though it requires more calculations than Taylor series.

3. Splines: This method divides the function into segments, using cubic polynomials to approximate ( tanh ) within each segment. It focuses on speed over accuracy.

4. IEEE-754 Floating-Point Representation: Some methods optimize calculations by manipulating the bit representation of floating-point numbers directly, leading to efficient approximations.

5. K-TanH Algorithm: This method uses integer operations and a lookup table to approximate ( tanh ) efficiently, making it suitable for hardware implementation.

6. Schraudolph's Method: This technique approximates ( e^x ) using bit manipulation, which can also be adapted to compute ( tanh ).

7. Schraudolph-NG: An improved version of Schraudolph's method that increases accuracy by canceling errors in the numerator and denominator.

These methods are evaluated based on their approximation errors compared to standard implementations, balancing speed and accuracy for different applications.

Iranian state media has accused the U.S. of sabotaging its networking equipment during military operations, claiming devices from Cisco, Juniper, Fortinet, and MikroTik rebooted or disconnected unexpectedly, despite Iran being offline. They suggest this indicates a deep sabotage possibly through hidden backdoors in the equipment. However, these claims are unverified and skepticism is warranted as they come from state media.

The U.S. has not specifically addressed these allegations but has acknowledged conducting cyber operations against Iran's communications systems as part of Operation Epic Fury, which aimed to disrupt Iranian networks before strikes began.

Historically, the vendors named by Iran have faced security issues. For instance, Cisco's routers were intercepted by the NSA, and Juniper found unauthorized code in its firewalls. Despite these security concerns, the U.S. intelligence community attributes certain hacking incidents to state-sponsored actors, including those from China.

Additionally, Iran has experienced one of the longest nationwide internet shutdowns, remaining largely disconnected for over 52 days since the conflict began.

Researchers from Penn State have successfully captured a rare atmospheric phenomenon called corona discharge, which causes tree tops to glow during thunderstorms. This event was theorized for over 70 years but had never been observed outside of laboratory conditions. The team, led by meteorologist William Brune, traveled to Florida to study summer storms but had limited success until they encountered a major storm in North Carolina.

Using a specialized telescope system, they documented 859 instances of corona discharges on one tree and 93 on another nearby tree during the storm. These discharges occur when strong negative charges in storm clouds attract positive charges from the ground, creating an electric field at the tips of leaves that emits a faint glow. This process can help break down harmful chemicals in the atmosphere, such as volatile organic compounds and methane.

The researchers noted that while they have confirmed the existence of corona discharges in nature, many questions remain about their effects on trees and the environment. They plan to collaborate with biologists to further investigate these impacts. This research was supported by the U.S. National Science Foundation and highlights ongoing discoveries in atmospheric science.

The text discusses the evolution of AI agents from synchronous to asynchronous interactions. Traditionally, users interacted with agents through chat windows, but now agents are designed to operate in the background, performing tasks without constant human oversight. This shift creates challenges because the existing technology, primarily based on HTTP, is not well-suited for asynchronous communication.

Key points include:

1. Rise of Async Agents: AI agents are increasingly running in the background, integrating with various platforms (like WhatsApp) and performing tasks independently of user input.

2. Transport Issues: Current chatbots depend on a continuous HTTP connection for communication, which fails in asynchronous scenarios. This means results can't be sent to users if they're no longer connected.

3. Solutions in the Industry: Companies like OpenClaw and Anthropic are addressing these challenges. OpenClaw allows agents to work in external chat platforms, while Anthropic offers features like Routines and Remote Control to manage agent sessions.

4. Durable State vs. Durable Transport: The problem has two parts: maintaining the agent's state during interruptions and ensuring reliable communication between agents and users. While companies are improving state management, they still rely on HTTP polling for transport, which isn't ideal.

5. Future Directions: The author, working for Ably, proposes building a better transport system for AI agents based on real-time messaging. This system would allow seamless connections and disconnections, enabling users and agents to communicate without losing context, thus enhancing the overall functionality of AI agents.

In summary, the shift to asynchronous AI agents poses new challenges that current technologies struggle to address, but innovative solutions are being developed to improve communication and state management.

Summary of Software Engineering Laws

The text outlines 56 key principles and patterns in software engineering that guide the development of systems, team dynamics, and decision-making. Here are some important laws summarized:

1. Conway's Law: Organizations design systems that reflect their communication structure.
2. Premature Optimization: Optimizing too early can lead to complexity without real benefits.
3. Hyrum's Law: With enough users, all observable behaviors of a system will be depended upon, regardless of what the documentation states.
4. Boy Scout Rule: Always leave the code better than you found it, making small improvements whenever possible.
5. YAGNI (You Aren't Gonna Need It): Don’t add features until they are necessary to avoid over-engineering.
6. Brooks's Law: Adding more people to a late project can make it later due to communication overhead.
7. Gall's Law: Complex systems should evolve from simple, working systems.
8. Law of Leaky Abstractions: All non-trivial abstractions will eventually reveal their underlying complexity.
9. CAP Theorem: A distributed system can only guarantee two out of three: consistency, availability, or partition tolerance.
10. Dunbar's Number: There is a cognitive limit (about 150 relationships) to the number of stable relationships one person can maintain.
11. Ringelmann Effect: Individual productivity decreases as group size increases.
12. Peter Principle: Employees tend to be promoted to their level of incompetence.
13. Bus Factor: The minimum number of team members whose absence would endanger the project.
14. Dilbert Principle: Companies often promote incompetent employees to management roles to minimize their impact on technical work.

These laws highlight the complexities and challenges in software development, emphasizing the importance of team structure, communication, and thoughtful design practices.

Summary of "Garbage Collection Without Unsafe Code"

On February 6, 2024, an overview was presented about creating a garbage collection (GC) library for Rust called safe-gc, which operates without using any unsafe code. Previous GC libraries in Rust typically incorporate unsafe code internally, but safe-gc aims to provide a completely safe API for users.

Key points about safe-gc include:

1. Implementation: Safe-gc has zero unsafe code in both its API and implementation, ensuring that all operations are safe. It uses a forbid(unsafe_code) directive to enforce this.

2. Usage: Users define their GC-managed types using the Gc<T> type, which allows for automatic management of references to other GC objects. Users implement the Trace trait to help the collector identify object references, which is crucial for avoiding memory errors.

3. Performance: While safe-gc is designed for safety, it is not highly optimized for performance compared to other GC libraries.

4. Garbage Collection Process: The library implements a mark-and-sweep algorithm:

   • Mark Phase: It identifies which objects are still reachable from active references (roots).
   • Sweep Phase: It collects objects that are no longer reachable and reclaims their space for future allocations.

5. Root Management: Safe-gc uses Root<T> types to ensure that objects stay alive during garbage collection, preventing unintentional deletions.

6. Finalization: The library avoids unsafe finalizers by using Rust's Drop trait without needing access to the heap, thus minimizing risks associated with object cleanup.

7. Future Improvements: The initial intention was to implement a copying collector, but due to complexities in managing heterogeneous types, the mark-and-sweep method was favored for its simplicity and effectiveness.

In conclusion, safe-gc is a significant advancement in Rust's garbage collection landscape, providing a safe and fun way to manage memory without the pitfalls associated with unsafe code.

On April 20, 2026, Congressman Blake Moore introduced the AI Children's Toy Safety Act, which seeks to prohibit the use of artificial intelligence chatbots in toys for children in the U.S. He expressed concerns that these chatbots could compromise children's data privacy, create addictive behaviors, and expose kids to inappropriate content.

Moore emphasized the importance of keeping AI development ethical and protecting children's well-being, stating that children's toys should not be used for data collection or manipulation.

Currently, many AI chatbot services have age restrictions, but their technology is still being used in children's toys. Test results indicated that some AI toys often engaged in inappropriate conversations. The bill aims to ensure that children are not influenced by AI technologies in their play and development.

The author appreciates the engaging comments on their blog but also faces challenges with spam. They use a tool called Antispam Bee to filter out hundreds of spam comments daily, but some still slip through. A recent example includes three comments that seem to reply to each other and appear normal at first glance. However, one of them contains a link to a dubious casino and all three comments come from the same IP address in the Philippines. They were posted three minutes apart, which is suspicious. Upon closer inspection, the comments seem to lack meaningful content and resemble AI-generated text. The author notes that while technological solutions can help, they may also make it harder for genuine commenters, as spammers will always find ways to bypass barriers.

This text discusses anonymous credentials, a privacy-focused method allowing users to authenticate on websites without revealing their identities. The system involves three main parties: an Issuer that provides credentials, Resources like websites, and Users who obtain and use these credentials.

Key features of an effective anonymous credential system include:

1. Usage Limitation: The ability to restrict how often a credential can be used to prevent misuse, such as credential cloning.
2. Expressiveness: Allowing users to prove various claims using their credentials without revealing unnecessary information.

The post then introduces two real-world systems:

1. Privacy Pass: A widely-used anonymous credential standard, employed by major companies like Cloudflare and Apple. It allows users to receive and use simple, single-use credentials (similar to a wristband) that confirm ownership without revealing identity. Privacy Pass uses blind signatures for credential verification, ensuring anonymity and security.

2. Google's Proposal for Anonymous Age Verification: This is a future initiative aimed at improving privacy during age verification online.

The author notes that while Privacy Pass is effective and widely used, it lacks advanced features needed for challenges like age verification. The next post will explore Google's new approach, which aims to address these issues.
