Apple and Google are expanding their use of hardware-based attestation, which is a way to ensure that only approved devices can access certain services. Both companies have similar systems: Google's Play Integrity API and Apple's App Attest API. These systems are being adopted by banks and government services, and Apple has already made hardware attestation a requirement.

The main goal of this technology is to restrict the use of non-approved hardware and software, which is often framed as a security feature. However, critics argue that it primarily serves to limit competition, effectively locking users into Apple and Google ecosystems. As a result, users may become unable to access services unless they have a device that meets these requirements.

For example, Google's reCAPTCHA is planning to require verification through certified devices, which could limit access for users with non-approved operating systems, including desktop systems. This trend is seen as anti-competitive, especially since Google can decide what devices are allowed.

Overall, the move towards hardware attestation is raising concerns that it prioritizes corporate control over user security and freedom, limiting access to important services for those without approved devices.

The main advice from the text is to avoid doing what locals do when traveling. While many suggest following locals for an authentic experience, the author argues that locals often have unexciting daily routines. Instead, tourists, who are eager and fresh, can explore freely and create memorable experiences. The author contrasts the joy of tourists enjoying activities like canoeing with locals who dismiss such experiences as "tourist traps." Ultimately, tourists should embrace their unique opportunities to have fun while traveling, rather than trying to mimic locals.

The author was an early supporter of AWS (Amazon Web Services) and praised it for revolutionizing cloud computing, allowing startups to quickly set up their systems. However, over 15 years, their enthusiasm faded due to several frustrations:

1. Lack of Official Libraries: AWS didn't create its own client libraries for programming languages, relying instead on the community.
2. Slow Updates: AWS took too long to transition from Python 2 to Python 3.
3. DynamoDB Issues: The author had a very negative experience with DynamoDB, citing high costs and inefficiency.
4. High Costs: They criticized AWS for expensive data egress fees and complex billing practices.
5. Complexity: The author found AWS's Identity and Access Management (IAM) system overly complicated, as well as the overall complexity of AWS services.
6. Vendor Lock-in: They felt trapped by AWS Lambda and its associated complexities.
7. Open Source Disputes: AWS was accused of undermining open-source projects by creating competing services.

Eventually, the author's dissatisfaction led them to move away from AWS entirely, keeping only a few services. However, they recently returned for specific tests but faced issues with account suspension due to security protocols. This experience reminded them of their previous frustrations with AWS and reinforced their decision to leave the platform. They plan to move their remaining services off AWS in the future.

Summary of Bambu Lab Controversy

Louis Rossmann, a prominent advocate for the Right to Repair, has publicly criticized 3D printer manufacturer Bambu Lab after the company threatened legal action against an independent developer, Pawel Jarczak. This developer was working on a project called OrcaSlicer, which would allow better integration with Bambu Lab's printers. In response to Bambu Lab's cease and desist letter, Rossmann pledged $10,000 to help cover Jarczak's legal fees and encouraged the community to support him through crowdfunding.

Rossmann expressed his frustration with Bambu Lab in a video, where he urged Jarczak to continue his work despite the company's threats. He emphasized the Right to Repair movement, which argues that consumers should be able to fix and modify products they own without restrictions from manufacturers. Many Bambu Lab printers are designed in a way that makes them difficult to repair or modify, which has raised concerns among users.

The public response to Rossmann's video has been overwhelmingly supportive, with many individuals expressing their willingness to contribute financially to Jarczak's legal defense. The situation highlights ongoing tensions in the tech industry between consumer rights and corporate control over products.

The article discusses the complexities of handling idempotency in API requests, particularly in payment systems. Idempotency ensures that making the same request multiple times has the same effect as making it once. While the basic concept seems simple—by using an Idempotency-Key to identify requests and storing their responses—the challenges arise when the same key is used for different requests or when requests arrive out of order.

Key Points:

1. Basic Idempotency: The first request with a unique key will create a payment. Subsequent requests with the same key should ideally return the original response. However, problems arise with concurrent requests, partial successes, and different request bodies.

2. Complex Scenarios:

   • If a second request arrives while the first is still processing, it complicates concurrency control.
   • If the first request fails after affecting external systems, the state of the operation becomes unclear.
   • Different request bodies using the same key can lead to ambiguity about whether it’s a retry or a new operation.

3. Defining Idempotency: An operation is idempotent if repeating it doesn’t change the outcome. This applies to various HTTP methods (e.g., PUT or DELETE), but POST requests usually require additional logic to ensure idempotency.

4. Idempotency Record Structure: To manage idempotency effectively, a database record should capture:

   • Who owns the request (tenant, user, etc.).
   • The operation's meaning.
   • The expected outcome for replaying requests.

5. Handling Conflicting Requests: The server should clearly define its behavior for different scenarios, such as:

   • Replaying the original response for repeated identical requests.
   • Rejecting requests with the same key but different content to catch client errors.

6. State Management: A clear state management system (e.g., IN_PROGRESS, COMPLETED, FAILED) is essential for handling retries and ensuring proper recovery from failures.

7. Response Management: Storing full responses for replay can be beneficial, but it also raises concerns about data privacy and storage costs.

8. Expiration and Cleanup: Idempotency records should have a defined expiration to avoid indefinite storage. Cleaning up these records must be done carefully to prevent losing critical state information.

9. Testing and Monitoring: It's vital to test various failure modes and monitor metrics related to idempotency, such as duplicate requests and stale states.

10. Design Decisions: Ultimately, the design of idempotency mechanisms should align with business needs and the potential impact of duplicate operations.

In summary, while idempotency appears straightforward, it involves careful design to handle various edge cases and ensure that operations behave consistently, especially in distributed systems like payment processing.

Summary: Emerich Juettner: The One Dollar Counterfeiter

Emerich Juettner, also known as Edward Mueller, was an unlikely counterfeiter who operated quietly in New York City. Born in Austria-Hungary in 1876, he led a modest life, working various jobs after emigrating to the U.S. Following the death of his wife in 1937, he struggled financially and turned to counterfeiting one-dollar bills using basic engraving techniques in his apartment.

Despite his crude methods—producing bills with poor quality paper and ink—Juettner successfully evaded the authorities for nearly a decade. His low-scale operation focused on the fact that few people scrutinized one-dollar bills closely. The U.S. Secret Service became aware of his counterfeit bills but struggled to identify him.

In January 1948, children discovered some of Juettner's engraving plates and counterfeit bills, leading to his arrest. During questioning, he revealed that he had been making the bills for years, ensuring no one lost more than one dollar. His humble approach and lack of greed garnered public sympathy, resulting in a light sentence of just a year and a day in prison, of which he served four months.

After his release, Juettner gained fame, and his story was adapted into the film Mister 880. He lived the rest of his life in Long Island, passing away in 1955 at the age of 79.

In the first four months of 2026, Spain's average wholesale electricity price was €44 per megawatt-hour, significantly lower than Italy (€127), Germany (€96), and the UK (€103). This marks a striking turnaround for Spain, which used to have one of Europe’s most expensive electricity markets due to reliance on fossil fuels like coal and gas.

Over the past 25 years, Spain has transformed its energy mix. Coal has almost vanished, gas has decreased from 30% to about 19%, while nuclear power remains steady at 19%. Wind and solar energy have surged, with wind providing 20% and solar 22% of generation in 2025. By 2022, renewable energy sources combined (wind and solar) generated more electricity than all fossil fuels together.

This shift has led to a significant drop in wholesale prices because gas is no longer the primary price-setter. While gas accounted for 55% of price-setting hours in 2022, it fell to just 9% in early 2026.

However, the wholesale price does not reflect what households pay, which is higher than the EU average due to additional taxes and charges. Despite low wholesale prices, Spanish households faced an average electricity bill of €0.265/kWh in 2025, placing them above many other European countries.

Spain’s transition to renewables has highlighted the need for grid modernization to handle stability issues, especially after a major blackout in April 2025 that was incorrectly blamed on renewable energy. Experts suggest that improvements in grid management are necessary for all European countries to ensure a reliable power supply.

Overall, Spain is now seen as a model for integrating renewables and achieving low electricity prices, but challenges remain regarding grid stability and future energy costs.

LLMorphism is the belief that human thinking is similar to how large language models (LLMs) operate. As conversational LLMs become more common, this belief may become more widespread. People might assume that if LLMs can talk like humans, then humans must think like LLMs. This is a flawed assumption because just because LLMs can produce human-like language doesn't mean their thinking processes are the same as ours.

LLMorphism can spread in two ways:

1. Analogical Transfer - People project LLM characteristics onto human thinking.
2. Metaphorical Availability - The language used for LLMs starts to influence how we describe human thought.

The author distinguishes LLMorphism from other concepts like mechanomorphism (viewing humans as machines) and anthropomorphism (attributing human traits to non-humans).

The implications of LLMorphism affect various areas, including work, education, healthcare, and creativity. The author argues that the public discussion is missing a key point: we might be giving machines too much credit for intelligence while underestimating human cognition.

The writer discusses a project involving a Finnish-English dictionary called Taskusanakirja (tsk), which needed to implement an efficient search-as-you-type feature. Initially, they used a trie data structure to handle prefix searches, but this became impractical due to the complex nature of Finnish, which has many word variations. To address this, they switched to using a 3 GB SQLite database with Full Text Search (FTS) for word inflections, but this required a large download, which was not ideal.

After a period of software engineering experience, the author decided to explore rewriting the project in Rust, inspired by a method for using finite state transducers (FSTs) to compactly represent data. This led to a significant reduction in size from 3 GB to just 10 MB, achieving a 300x memory reduction. The FSTs proved to be highly effective for the dictionary's needs, particularly because they can efficiently handle the suffixes common in Finnish.

The author emphasizes the value of experimenting and learning through problem-solving, even if it means doing things that might seem less optimal at first. They highlight that the new version of the dictionary will be much smaller and more efficient, aligning with the goal of making it accessible for users with older devices.

Let-go is a programming language similar to Clojure, designed to run on the Go platform. It is about 90% compatible with JVM Clojure and is packaged as a small (~10MB) static binary that starts up quickly, taking around 7 milliseconds, which is significantly faster than JVM and other alternatives.

The project began in 2021 as a joke, but it has proven to be quite effective. It feels like using real Clojure and includes features like an nREPL server for development tools. It can be easily integrated into Go programs and is suitable for various tasks such as creating command-line interfaces, web servers, data processing scripts, and even systems programming.

The language is built on a simple compiler and a stack virtual machine specifically designed for Clojure-like code. It can generate portable bytecode and standalone binaries.

However, Let-go is not a complete replacement for Clojure. It does not support loading Java JAR files, lacks some Java APIs, and may not run existing Clojure projects without changes.

Feedback, issues, and contributions are welcomed from users who try it out.

Summary: The Intolerable Hypocrisy of Cyberlibertarianism

The author reflects on the Internet's evolution, contrasting it with the pre-Internet era, which was often frustrating and chaotic. Despite appreciating the Internet's conveniences, the author criticizes the foundational ideology of cyberlibertarianism—a belief in absolute freedom and minimal regulation—that has shaped the digital landscape.

Key points include:

1. Historical Context: John Perry Barlow's "A Declaration of the Independence of Cyberspace" (1996) promoted the idea that the Internet should be free from government control, framing it as a space for individual self-determination. However, this ideology has led to unintended consequences.

2. Ideological Flaws: The four pillars of cyberlibertarianism—technological determinism, radical individualism, free-market absolutism, and a fantasy of communitarian outcomes—are critiqued. The author argues these ideas falsely equate individual freedom with corporate interests, undermining true social equity.

3. Consequences of Deregulation: The author points out that the promise of a decentralized, harmonious community has not materialized. Instead, large corporations have gained control over the Internet, often prioritizing profits over user welfare while ignoring the need for governance and regulation.

4. Reality Check: The article emphasizes that the Internet has not made people better or more informed. Instead, it has allowed misinformation to flourish, creating echo chambers where individuals reinforce their own beliefs without facing differing viewpoints.

5. Call to Action: The author argues for the need to develop an ethical framework for the Internet, recognizing that just because something is profitable does not mean it is beneficial for society. There's a call to evolve from the flawed cyberlibertarian ideology to create a healthier digital environment.

In conclusion, while the Internet has brought many benefits, the foundational beliefs that shaped its development have led to significant issues that need to be addressed for a better future.

The "Show HN Merit Ranking" is a system designed to rank Show HN posts based on their quality, using a combination of TrueSkill and a language model (LLM) to evaluate them. The main idea is that upvotes on Hacker News (HN) often favor projects that are easy to assess from a screenshot, while more complex technical projects may receive fewer upvotes. This ranking system aims to give a fairer evaluation by considering factors like depth, novelty, and craftsmanship.

Here’s how it works:

1. Data Collection: It gathers Show HN posts using the Algolia API.
2. Content Extraction: It extracts the content of the posts to evaluate them.
3. Judging: A language model compares pairs of posts based on a rubric that prioritizes depth over marketing flair.
4. Rating: The system uses TrueSkill to rank the posts and identifies discrepancies between merit and upvotes.

The process involves multiple stages, and users can run it with specific commands to analyze either 50 or 1,000 posts.

Limitations: The system does not replace HN's original ranking. The LLM has biases and may favor well-documented projects. The output should be seen as one perspective rather than definitive truth.

Nayuta Space is developing a unique rocket, the Black Bird-R, which features a "bellyflop" landing method for its first-stage booster. Recently, they completed several funding rounds to support this project. The company plans to test the rocket's second-stage engine, which uses liquid methane and oxygen, and conduct wind tunnel tests to refine its design.

In a significant change announced in August 2025, Nayuta Space outlined a new recovery method for the rocket's first stage, which will descend unpowered and land on its side using thrusters, instead of landing upright. This approach is expected to increase payload capacity and reduce costs.

The development of the Black Bird-R is progressing, with recent tests on its control surfaces to ensure proper pitch, yaw, and roll during descent. Nayuta Space has also signed agreements to produce the rocket's electrical systems and is currently building components for the rocket. While the first flight date is not yet announced, several tests are planned for 2026. The Black Bird-R will be around 70 meters tall and utilize a two-stage design with multiple engines. The company is also considering a reusable second stage with a similar landing technique.

Summary of "Surfel-based Global Illumination on the Web"

The blog post explores the use of WebGPU to create real-time global illumination using a method called surfels—small surface patches. The author discusses the potential for this technology to enable complex rendering pipelines on the web.

Key points include:

1. Introduction to Surfels: Surfels are flat discs in 3D space that help simulate how light interacts with surfaces, allowing for efficient global illumination without needing high screen resolution.

2. Surfelization Process: This involves converting traditional geometry into surfels through several computational steps, including rendering depth and normals, maintaining a surfel pool, and conducting spatial analysis.

3. Grid Structure: A spatial grid organizes surfels for quicker access, improving performance by limiting the number of surfels each pixel interacts with.

4. Ray Tracing with BVH: A Bounding Volume Hierarchy (BVH) is used to efficiently manage ray tracing, allowing for realistic light interactions without needing dedicated hardware support.

5. Temporal Stability: The post discusses methods to stabilize the rendering over time, including a multi-scale mean estimator to balance responsiveness with noise reduction.

6. Occlusion Handling: To prevent light leaks (where light incorrectly passes through walls), a depth atlas gives surfels awareness of their surroundings.

7. Resolve Pass: The final step involves transferring light information from surfels to screen pixels, utilizing various factors (like distance and orientation) to ensure accurate blending.

The author acknowledges the technical challenges faced, such as browser limitations and the complexity of the algorithms. Despite these hurdles, the project demonstrates the potential of real-time global illumination in web applications, offering a glimpse into the future of graphics on the web. The post concludes by celebrating the progress made possible by WebGPU technology and the community's contributions to this innovative approach.

The text discusses the derivation of the elimination tree for the sparse Cholesky algorithm, which is used to compute a matrix A as the product of a lower triangular matrix L and its transpose. The elimination tree helps identify where non-zero entries appear in L and shows the dependencies between tasks in the factorization process.

Key points include:

1. Purpose of the Elimination Tree: It indicates non-zero entries in L that may not be present in the original matrix A and outlines the dependencies of operations needed for the Cholesky factorization, even when A is sparse.

2. Dense vs. Sparse Cholesky: The algorithm starts with a dense version of Cholesky factorization, which is then adapted for sparse matrices. The process includes scaling and updating the matrix, where fill-in occurs (new non-zero entries added).

3. Task Dependency Graph (DAG): The operations form a DAG that can be simplified to remove unnecessary computations. This results in a pruned graph that guides the factorization process.

4. Column Elimination Tree: This tree structure captures the essential relationships and dependencies among matrix columns, helping to determine where new non-zeros will appear. It is derived from the initial non-zero pattern of A.

5. Symbolic and Numeric Factorization: The elimination tree is used to efficiently determine the non-zero pattern of L before performing numeric computations. This avoids unnecessary checks for existing entries and optimizes the factorization process.

6. Computing the Elimination Tree: The tree is constructed using a specific algorithm that processes the matrix rows and tracks dependencies among them.

The overall goal is to provide a clearer and more practical understanding of how elimination trees function within the sparse Cholesky factorization process, connecting the theoretical aspects with the algorithmic implementation.

Summary of "On Forking the Web"

Overview: This document outlines ideas for creating an alternative web specification that aims to retain the positive aspects of the current web while addressing its issues. It emphasizes simplicity, clear versioning, and strict grammar.

Key Goals:

1. Simplicity:

   • The new specification should be short and easy to understand, facilitating the development of diverse browsers. A potential limit of 1.44 MiB is suggested for the entire specification.

2. Semantic Versioning:

   • Instead of frequently changing specifications, a clear versioning system (like 1.2.3) is proposed. This would allow developers to rely on a stable standard and ensure compatibility across different browser versions.

3. Strict Grammar:

   • The specification should have a clear and formal grammar that can be easily parsed. Non-compliant pages will not be rendered, encouraging adherence to the standard and reducing the need for complex fixes by browsers.

4. Reusing HTML:

   • The possibility of creating a simpler subset of HTML is considered, but the complexity of HTML parsing may pose challenges.

5. Resistance to Standard Capture:

   • The document highlights the risk of monopolistic entities manipulating standards for profit, which complicates the web and hinders competition. Strategies to prevent this need further exploration.

6. Text First:

   • Emphasizing written text as the primary medium ensures flexibility in information sharing, making it accessible on various screen sizes.

7. No Scripting:

   • The specification will avoid scripting to streamline functionality. Instead, it will support native applications for interactivity, promoting efficiency and device optimization.

Non-Goals: The aim is not to replicate the web's features but to create a platform for sharing information without needing complex software.

Summary: What Causes Lightning?

Scientists are making progress in understanding the complex phenomenon of lightning, which has puzzled researchers for centuries. Joseph Dwyer, a physicist, shifted his focus from studying cosmic events to investigating thunderstorms in Florida, where he discovered that lightning is a significant mystery yet to be solved.

Historically, researchers thought lightning occurred due to strong electric fields generated by moving ice crystals in storm clouds, much like sparks created between charged metal balls. However, modern studies reveal that thunderclouds often lack the necessary electric strength to produce lightning. Recent findings suggest that high-energy processes, similar to those seen in cosmic events, may play a critical role in lightning initiation.

For example, researchers have detected gamma rays and other high-energy phenomena in storm clouds. Dwyer's theory proposes that runaway electron avalanches, which can occur in electric fields, might amplify the conditions needed for lightning. This idea is supported by recent data from the ALOFT mission, which showed that storm clouds exhibit various unexpected behaviors.

However, some evidence suggests that cosmic-ray showers from space might also trigger lightning, indicating that multiple mechanisms could be at play. As scientists continue to explore this topic, they are uncovering new complexities, leading to a deeper understanding that challenges previous theories. The investigation into lightning remains ongoing, with researchers seeking to clarify how different factors contribute to this awe-inspiring natural phenomenon.

The European Parliamentary Research Service (EPRS) has identified virtual private networks (VPNs) as a problem in enforcing online age verification for accessing adult content. They argue that VPNs allow minors to bypass age checks, which is a loophole in current laws aimed at protecting children online.

As more countries, including the UK, implement strict age-verification rules, VPN usage has increased, particularly among younger users. The EPRS suggests that some policymakers believe that age verification should be required for accessing VPN services as well, but this could threaten user privacy and anonymity.

Many current age-verification methods are easy for minors to evade, and new approaches, like "double-blind" verification used in France, are being explored to enhance security without compromising user identity. Additionally, Utah has passed a law targeting VPN use in age verification, indicating that regulations may tighten further.

The EPRS anticipates that VPN providers may face more scrutiny as the EU updates its cybersecurity and online safety laws to address these issues.

Large Language Models (LLMs) are changing how we do knowledge work by allowing tasks to be delegated to them. However, this delegation relies on trust that the LLM will complete tasks accurately. To investigate this, researchers created DELEGATE-52, a test that simulates long workflows requiring detailed document editing across 52 different fields, like coding and music notation.

In experiments with 19 LLMs, including advanced models like Gemini 3.1 Pro and GPT 5.4, it was found that these systems often degrade documents during tasks. On average, they corrupted 25% of the document content over long workflows, with some models performing even worse. The study showed that using tools alongside the models didn't improve their performance, and issues worsened with larger documents or longer interactions. Overall, the findings indicate that current LLMs are not reliable for delegated tasks, as they can introduce significant errors that accumulate over time.

The Conasauga River in northwest Georgia has been contaminated with harmful "forever chemicals," specifically PFAS, due to the carpet industry’s use of these substances for stain resistance. Bob Shaw, CEO of Shaw Industries, famously confronted 3M executives about the implications of their Scotchgard product, which was found to be harmful. Despite warnings from the EPA and scientific studies indicating health risks, carpet manufacturers continued to use similar chemical alternatives, contributing to severe pollution in the region.

The chemicals have infiltrated the environment, affecting drinking water and leading to health issues among local residents. Many individuals, like Dolly Baker and the Jackson family, have reported high levels of PFAS in their blood and associated health problems, including thyroid issues and cancer risks. The industry has largely evaded responsibility, often blaming chemical manufacturers for the contamination.

State and federal regulations have been insufficient, allowing carpet companies to operate with minimal oversight. Recent investigations revealed that Dalton Utilities, responsible for treating wastewater from the carpet mills, has struggled to manage PFAS contamination effectively. Legal actions have emerged as communities seek accountability, with residents filing lawsuits against both carpet manufacturers and chemical suppliers.

As the extent of contamination becomes clearer, public health concerns grow, and local residents demand action to address the toxic legacy left by the carpet industry.

In his declaration, John Perry Barlow addresses governments, asserting that they do not belong in Cyberspace, a realm defined by freedom and creativity. He emphasizes that this new digital world is independent of traditional governmental control and cannot be governed by laws based on physical matter. Barlow argues that governments have not earned the consent of the people in Cyberspace and cannot enforce their rules there.

He states that Cyberspace is a space for open expression, free from discrimination and coercion. Barlow criticizes existing laws, like the Telecommunications Reform Act in the U.S., which he believes undermine the ideals of democracy and freedom. He views attempts by governments to regulate the internet as futile and outdated, as they cannot control the free flow of ideas and communication.

Barlow calls for a new social contract based on ethics and mutual respect, rather than imposed authority. He envisions a civilization in Cyberspace that is more just and humane than the physical world governed by outdated powers. Ultimately, he declares that their thoughts and identities are free from government control, even as they acknowledge physical laws over their bodies.

Singapore has implemented new guidelines allowing caning as a punishment for male students aged nine and older who bully others, including through cyberbullying. This measure is seen as a "last resort" after other disciplinary actions have failed. Under the rules, students can receive up to three strokes of the cane, with strict protocols ensuring safety and requiring approval from the principal and authorized teachers.

The decision follows a review prompted by serious bullying incidents and concerns from international organizations like UNICEF, which argue that corporal punishment can harm children's mental and physical health. The education minister stated that the maturity of the student and the potential for learning from the punishment would be taken into account.

Female students will face alternative punishments, such as detention or suspension. This caning practice is part of a broader context in Singapore, where corporal punishment is still used for serious crimes among male offenders.

Brave has introduced a simpler version of its product. Whether this version is useful for you depends on how much you value privacy.

GrapheneOS has released an update that addresses a VPN leak vulnerability in Android, which could expose users' real IP addresses even when VPN protections were enabled. This issue was identified by researcher "lowlevel/Yusuf" and affected Android 16. The leak occurred due to a flaw in a new QUIC connection feature, allowing apps to bypass VPN restrictions. Google classified the issue as "Won't Fix," prompting GrapheneOS to implement a solution by disabling the problematic feature in their latest release.

In addition to fixing the VPN issue, the update includes the May 2026 Android security patch, enhancements to memory management, updates to the Linux kernel, and improvements to the Vanadium browser. While there is a temporary workaround for stock Android users, it requires developer access and may not be reliable in future updates. Overall, GrapheneOS continues to prioritize privacy and security for its users, particularly those using Google Pixel devices.

Jens Axboe has developed new Linux kernel patches that boost per-core I/O performance by about 60%. This initiative followed his presentation at the Linux storage summit in Croatia, where he compared Linux I/O performance to the Storage Performance Development Kit (SPDK).

While returning from the summit, Axboe created a proof-of-concept patch that initially aimed for a 50% performance increase but ultimately achieved 60%. These patches focus on optimizing how buffers are managed during I/O operations, specifically using IO_uring, the NVMe PCI driver, and block code in the Linux kernel. Axboe hopes these improvements will soon be incorporated into the main Linux kernel.

The author critiques OpenAI's use of WebRTC for voice AI, arguing it's not suitable due to its aggressive handling of audio packets which can lead to dropped prompts during poor network conditions. They share their experience of working with WebRTC in the past and highlight its complexity, mentioning the numerous standards involved and the technical challenges, particularly around connection stability and latency.

Key points include:

1. WebRTC Limitations: It's designed for real-time applications like conferencing, which can degrade audio quality for voice AI tasks. The author prefers waiting for accurate responses rather than risking poor quality.

2. Connection Issues: WebRTC's connection setup requires multiple round trips, which adds latency and can lead to connection drops when IP addresses change.

3. Hacks and Workarounds: Due to WebRTC's limitations, developers often implement workarounds that can complicate load balancing and networking.

4. Alternative Solutions: The author suggests using WebSockets for audio streaming as it leverages existing infrastructure and is easier to scale. They also recommend exploring QUIC as a more efficient protocol, which offers better load balancing and connection stability.

5. Conclusion: The author believes that while OpenAI's engineers are talented, WebRTC is not the best choice for voice AI, likening it to a poorly cast movie role. They advocate for a shift to QUIC for better performance and user experience.

This morning, the database detected a duplicate UUID (v4), which is surprising because UUIDs are designed to be unique. The original UUID was created in 2025, and today, a new record was added with the same UUID: b6133fd6-70fe-4fe3-bed6-8ca8fc9386cd. The team is using the UUID package from npm to generate these IDs, simply calling uuidv4() to create them. Given that there are only about 15,000 records in the database, the chance of this happening is statistically very low. The author is puzzled and is asking if anyone else has experienced a similar issue.

Summary of "Mythical Man Month" by Fred Brooks

In the early 1960s, Fred Brooks oversaw the development of IBM's System/360 computers. He wrote "The Mythical Man-Month," published in 1975, which has become a key book in software development. Although some ideas may seem outdated today, many lessons remain relevant.

A central idea in the book is Brooks's law: “Adding manpower to a late software project makes it later.” This is due to the increasing complexity of communication as more people join a project. Without careful management of communication, progress can stall.

Another important lesson is the concept of "conceptual integrity." Brooks believes that a well-designed system should reflect a unified set of ideas, rather than a mix of uncoordinated features. This focus on simplicity and coherence has greatly influenced the author's career.

The anniversary edition of the book is recommended as it includes Brooks's influential 1986 essay “No Silver Bullet.”

Sasha Levin sent a message regarding a new feature called "killswitch" designed to help mitigate security issues in the Linux kernel.

Key Points:

1. Purpose of Killswitch: The killswitch allows an administrator to disable specific kernel functions that may have security vulnerabilities by making them return a fixed error code, preventing any buggy behavior until a proper fix is implemented.

2. Activation: To engage the killswitch, an admin can use a command to specify which function to disable. For example, the command echo "engage af_alg_sendmsg -1" > /sys/kernel/security/killswitch/control would disable the af_alg_sendmsg() function.

3. Immediate Effect: Once engaged, the specified function will return an error immediately without executing its actual code, reducing the risk from known vulnerabilities until a patched kernel can be booted.

4. Temporary Measure: The killswitch is meant as a temporary fix, as it will revert to normal operation after a system reboot.

5. Implementation Details: The feature includes documentation, configuration options, and support for testing to ensure it operates correctly.

6. Kernel Tainting: Engaging the killswitch will mark the kernel as "tainted," indicating that its behavior has been altered from the original source.

This feature aims to provide a quick response to vulnerabilities, especially for functions that are not widely used, allowing systems to remain secure while awaiting official updates.

The text describes a new local storage engine that avoids using fsync during write operations, which is typically a requirement for ensuring data durability in storage systems. Instead, this engine employs techniques like pre-allocation, O_DIRECT writes, and an SSD-aware journal to maintain data integrity during crashes.

Key Points:

1. No fsync: The engine eliminates the expensive fsync calls for operations like PUT and DELETE. It relies on fixed-size pre-allocated files and a journal system that ensures crash consistency.

2. Performance Improvement: The engine significantly outperforms traditional methods that use fsync. In benchmarks, it achieved over 190,000 operations per second, which is much faster than the alternatives that incorporate fsync.

3. Design Constraints: This storage solution is designed specifically for SSDs and does not support HDDs. It focuses on simple key-value (KV) operations, which allows for more efficient data handling.

4. Components: The engine consists of three main parts:

   • Index: Maps keys to value locations, primarily stored in memory.
   • Journal: Records changes for crash consistency without storing actual value data.
   • Data Area: Manages where the values are stored and allows for predictable allocation and fast deletes.

5. Operation Overview: When performing a PUT operation, the engine allocates space, writes the data directly, updates the journal, and modifies the index, all without requiring fsync.

6. Performance Metrics: The engine's throughput is significantly higher than traditional filesystem-based approaches, with lower average latency.

7. Limitations: The design is narrow in scope and not suitable for general-purpose use. It also depends on specific SSD durability assumptions, meaning it may not work well with all types of storage devices.

In summary, the new storage engine achieves high performance by removing fsync, relying on direct writes, and managing its own data structures, making it suitable for specific high-speed applications.

Summary of the IBM Selectric Composer

Introduction to the Selectric Composer (1964)
The IBM Selectric Composer was an innovative typewriter that changed how text was produced. Unlike earlier typewriters that used fixed-width fonts, it allowed for variable letter widths, improving typographic quality.

Key Features

• Variable Widths: Letters could belong to one of seven width groups, allowing for better spacing and more natural text appearance.
• Color-Coded Units: Different font sizes and styles used a color-coding system to indicate the correct scaling settings.
• Precision Engineering: The “golf balls” that held type were made from nickel-plated plastic and were precisely manufactured.

Font and Glyph Management

• The Selectric Composer had a limited number of typefaces and assigned fixed width units to each character, which sometimes led to awkward spacing.
• The system was designed based on the “Times” typeface, which created challenges when adapting other fonts due to varying letter widths.

Limitations
While the Selectric Composer was advanced for its time, it could not compete with metal type or photo typesetting. It found its niche in smaller publications and company documents but became outdated with the rise of desktop publishing in the 1990s.

Digitization of Fonts
To recreate fonts from the Selectric Composer for digital use, adjustments were needed to match the original sizes. The process involved calculating scaling factors and ensuring accurate cap heights for different font sizes.

Conclusion
Despite its limitations, the IBM Selectric Composer played a significant role in typographic history and laid the groundwork for future advancements in type-setting technology. It remains a notable example of innovation in the field.

Scientists are increasingly concerned about the Atlantic Meridional Overturning Circulation (AMOC), a crucial ocean current that warms northern Europe and affects global climate. Research suggests that the AMOC may be close to a "tipping point" where it could collapse, leading to severe consequences such as drier conditions in Europe, intensified storms, and weakened monsoons in Africa and Asia.

For decades, experts believed the likelihood of a shutdown was low, but recent studies indicate it could be as high as 50%. Iceland has even classified the risk of an AMOC shutdown as a national security threat.

The AMOC is driven by cold, salty water sinking near Greenland. However, climate change is warming these waters, making them less dense and disrupting the current. This could lead to a feedback loop that further slows the AMOC. Past events show that a shutdown could drastically alter climate conditions, as seen during the last ice age.

Current data suggests that the AMOC has begun to slow, but predictions vary on when a collapse might occur. Some models indicate a significant slowdown by the end of the century, while others predict it could take much longer or not happen at all. Despite these uncertainties, many scientists agree that even a weakening of the AMOC could have serious climate impacts, emphasizing the urgent need to reduce greenhouse gas emissions.

Mozilla reported that a team called Mythos has discovered 271 vulnerabilities in their software, and these findings have very few false positives. This means that most of the identified issues are real problems that need attention, making the work of Mythos reliable and valuable for improving security.

The article discusses the evaluation of Large Language Models (LLMs) in modeling real-world systems using TLA+, a formal specification language. The Specula team created SysMoBench, a benchmark to assess how well LLMs can generate accurate TLA+ specifications for various systems.

Key points include:

1. LLM Evaluation: The team tested LLMs like Claude, GPT, and others on their ability to create TLA+ specs for systems, comparing the output against actual system behaviors.

2. SysMoBench Overview: This benchmark comprises four evaluation phases:

   • Syntax: Checks if the spec compiles.
   • Runtime: Tests if the spec runs without errors.
   • Conformance: Validates if the spec matches the system's execution traces.
   • Invariant: Ensures key properties of the system are satisfied.

3. Findings: While LLMs excel in syntax (often scoring close to 100%), they struggle with conformance and invariant checks, averaging around 46% and 41% respectively. Common issues include:

   • Specifying unreachable states.
   • Missing states that the real system can reach.

4. Transition Validation: This method breaks down execution traces to evaluate each action's correctness, providing detailed feedback instead of a single score.

5. Challenges: There are still issues to address, such as trace sampling limitations, loss of information in state abstraction, and the need for manual setups for new systems.

6. Future Directions: The team plans to enhance SysMoBench and develop tools like Specula, which show promise in achieving full conformance in TLA+ modeling.

Overall, while LLMs show strong potential in generating TLA+ specifications, there is a significant gap between producing syntactically correct models and accurately reflecting the behavior of specific systems.

Summary of Getting Arrested in Japan

Japan is known for its safety, but strict laws can lead to unexpected arrests for minor infractions. If arrested, you will be taken to a police detention center (kōchi-sho) instead of a courtroom. Here, you may be held for up to 23 days while authorities investigate, with the possibility of extensions if further allegations arise.

Detention centers are harsh environments designed to exert psychological pressure. Conditions include disrupted sleep, limited communication, and strict schedules, often leading to mental exhaustion and even false confessions. In contrast to the U.S. system, which quickly involves courts and legal representation, Japan's system focuses on lengthy investigations before charges are filed.

Upon arrival at a detention center, you undergo thorough inspection and must comply with numerous strict rules. Cells are small, uncomfortable, and lack basic amenities. Daily routines are heavily regulated, with limited personal freedom and basic activities allowed.

Food is minimal and often inedible, adding to the distress of detainees. Most of your time is spent in isolation with little to no stimulation, leading to significant mental strain.

Communication is restricted to Japanese, and there are no visitors allowed. It is crucial to contact your embassy if arrested, as they can provide assistance and information.

The author shares their own traumatic experience of being detained for 35 days, highlighting the psychological toll and life disruptions caused by the system. The overall message is to be aware of the potential dangers in Japan's detention process.

In April, a blog post discussed a wooden typewriter from the Chinese model kit company ROKR. Initially thought to be a non-functional tribute, the typewriter actually works and can type in capital letters, although not as smoothly as traditional models. Priced at $119.99, it offers a unique and affordable way to experience typing.

The typewriter is made mainly of laser-cut wood, with some plastic and metal parts. An interview with the design team revealed that the project took about a year and a half to complete, focusing on recreating the tactile feel of a real typewriter while simplifying the design for assembly. The team aimed to provide a nostalgic typing experience that contrasts with modern digital tools.

ROKR has created two versions of the typewriter: the Classic (Black Gold) version and the Magic (Fairy Tale) version, catering to different aesthetic preferences. The design retains key aspects of traditional typewriters but incorporates simplified mechanics to suit the materials used. The team has also filed patents for their unique mechanisms.

Overall, the ROKR typewriter stands out as a functional piece that brings back the joy of typing, appealing to both nostalgic users and a new audience.

A Virginia man named Sohaib Akhter has been found guilty of deleting around 96 databases containing sensitive US government data, which occurred shortly after he and his twin brother Muneeb were fired from their jobs at a software supplier to the government. The brothers accessed an individual’s account without permission, and after being terminated, Muneeb used his access to delete the databases and attempted to cover up their actions.

Muneeb also copied thousands of sensitive files onto a USB stick and tried to access further sensitive equipment. Both brothers have a history of criminal activity, with Sohaib previously convicted for accessing sensitive data. He is facing additional charges related to illegal firearm possession.

Muneeb has not yet been convicted but faces serious charges, including downloading and exploiting stolen login information from various companies. If found guilty, he could face up to 45 years in prison.

The text discusses a new approach to improving the way retrieval-augmented agents access large knowledge bases. Traditional methods involve making several queries and refining them until useful information is found, which can be slow and inefficient.

The new method, called the SuperIntelligent Retrieval Agent (SIRA), aims to streamline this process. SIRA uses advanced techniques to combine multiple search attempts into a single, effective search. It focuses on identifying the best terms to find relevant evidence, rather than just what might seem relevant at first.

SIRA enhances documents with additional vocabulary and predicts useful terms that might be missing from the search queries. It also uses statistics to filter out terms that are too common or unlikely to be helpful. Finally, it makes a single, optimized retrieval call that combines the original query with the improved terms.

In tests, SIRA performed significantly better than existing methods, proving that a well-constructed search can be much more efficient than multiple attempts, while also being easy to understand and quick to use.
