A recent study from Stanford Medicine and the Arc Institute has discovered that the gut microbiome, which consists of bacteria in our intestines, plays a significant role in cognitive decline as we age. The research focused on mice and showed that changes in gut bacteria can affect memory and cognitive abilities.

Key points from the study include:

1. Gut-Brain Connection: The vagus nerve sends signals from the gut to the brain, influencing memory and cognition. Changes in gut bacteria can disrupt this communication, leading to cognitive decline.

2. Impact of Aging: As mice aged, their gut microbiome changed, favoring certain bacteria that were linked to memory decline. This decline was not fixed but could be influenced by the gut.

3. Restoring Memory: Stimulating the vagus nerve in older mice improved their memory, indicating that it’s possible to reverse some cognitive decline by addressing gut health.

4. Specific Bacteria: A particular bacteria, Parabacteroides goldsteinii, was found to increase in older mice and was associated with cognitive issues.

5. Inflammation Role: Changes in gut bacteria lead to inflammation that impairs the vagus nerve's ability to communicate with the brain, affecting memory formation.

6. Future Research: The researchers are looking into whether similar mechanisms exist in humans and aim to develop non-invasive methods to monitor and improve gut-brain communication to combat aging-related cognitive decline.

Overall, this study suggests that our gut health is crucial not just for digestion, but also for maintaining cognitive function as we age.

As of June 2025, US banks have lent nearly $300 billion to private credit providers, contributing to a total of $1.2 trillion in loans to non-depository financial institutions (NDFIs). This represents a significant increase, with loans to private credit now making up 10.4% of total bank lending, compared to just 3.6% a decade ago.

Moody's Ratings explains that banks are shifting towards private credit as they adapt to changing market conditions, seeking new partnerships with alternative asset managers to diversify their income and reduce risks. The top five banks in private credit lending are Wells Fargo, Bank of America, PNC, Citigroup, and JPMorgan Chase.

However, banks are facing challenges as they are both competing with and financing non-bank lenders. Moody's warns that asset quality issues may arise, as seen in the recent bankruptcy of Tricolor Holdings, which highlights the risks involved. Despite these concerns, the private credit sector has seen substantial growth, with assets under management tripling in the past decade.

Summary: The Cost of Indirection in Rust

The common belief that "every extra function call adds overhead" is often misleading, especially in Rust's async code. When developers worry about performance, they may sacrifice code readability and maintainability without a real gain.

For example, if a lengthy function arm is extracted into a separate async function, some team members might fear the additional function call will slow things down. However, this concern is often exaggerated. The Rust compiler can optimize such calls, sometimes producing the same performance as inline code.

Real performance costs come from significant operations like I/O, not from function call overhead, which is typically minimal. In fact, during release builds, the difference in performance between inline and extracted functions can be negligible.

It's essential to recognize that the cognitive load and complexity of maintaining code can outweigh the minor performance hits from function calls. Clean, well-named functions improve code clarity and make it easier for developers to understand and modify the system in the long run.

When deciding whether to inline or extract functions, prioritize readability and maintainability over minor performance concerns, and rely on profiling to identify genuine bottlenecks. Ultimately, good engineering balances performance with code clarity for better developer productivity.

We created rudel.ai because we realized we lacked insight into our Claude Code sessions. We used it daily but didn't know which sessions were effective, why some were abandoned, or if we were improving.

To address this, we developed an analytics tool. By analyzing 1,573 real sessions, we gathered over 15 million tokens and 270,000 interactions. Here are some surprising findings:

• Only 4% of sessions utilized skills.
• 26% of sessions were abandoned, often within the first minute.
• Success rates varied by task type; documentation was the most successful, while refactoring was the least.
• Patterns indicating abandonment emerged within the first 2 minutes.
• There’s currently no standard for what constitutes a 'good' session performance, and we are working on creating one.

Our tool is free and open source, and we're happy to discuss the data or our development process.

Summary of DDR4 Memory Initialization and Calibration

When DDR4 memory is powered on, it undergoes a series of steps to become operational. This process includes four main phases:

1. Power-up and Initialization: The memory controller activates the DRAM by applying power, resetting, and enabling the clock. It then configures mode registers and brings the DRAM into an idle state.

2. ZQ Calibration: This step fine-tunes the resistance of data pins (DQ) to ensure they function correctly. A precision resistor is used as a reference to adjust the internal resistors to the required value.

3. Vref DQ Calibration: In DDR4, a new termination style called Pseudo Open Drain (POD) is used for data lines. This replaces the older Center Tapped Termination (CTT) method, improving signal integrity and power efficiency. The memory controller sets an internal voltage reference (VrefDQ) during this phase.

4. Read/Write Training: Finally, the controller aligns the clock and data signals and adjusts for timing delays to ensure reliable data transfers. This includes various algorithms like Write Leveling and Read/Write Centering to optimize performance.

After these steps, the DRAM is ready for use. Periodic calibration may be necessary in environments with varying temperature and voltage to maintain performance and signal integrity.

Fungi, often overlooked, play a crucial role in the environment by creating soil, storing carbon, and significantly contributing to the global economy—valued at $55 trillion. Despite their importance, only a small percentage of the estimated 12 million fungal species are known, with just a few classified as endangered. One such species, Agarikon, has medicinal properties but is declining rapidly.

Fungi form essential partnerships with about 90% of plants, enhancing their nutrient and water absorption. They are vital for ecosystem health and carbon sequestration, with mycorrhizal fungi alone storing about 13 billion tons of carbon dioxide annually. However, fungi face threats from climate change and habitat loss, with only 10% of key fungal ecosystems protected.

Efforts are underway to raise awareness of fungi's importance. Initiatives like the Fungal Conservation Pledge aim to recognize fungi alongside plants and animals in conservation strategies. Recent scientific recognition, such as the Tyler Prize for Environmental Achievement, highlights the need for greater research and protection of fungi. Advocates believe we are beginning to witness a "fungal awakening" in environmental awareness and policy.

Summary of Emacs Internal #03: Tagged Union, Tagged Pointer, and Poor Man's Inheritance

This article discusses how GNU Emacs handles various Lisp data types using a single structure called Lisp_Object, leveraging concepts like tagged unions and tagged pointers to manage memory efficiently.

1. Polymorphic Types:

   • Emacs uses a structure to access different data types dynamically by storing a type identifier alongside data. This allows the program to check types before performing operations.

2. Tagged Union:

   • A tagged union combines different data types in a single structure but can be memory inefficient because it allocates space based on the largest type.
   • std::variant in C++ serves a similar purpose, ensuring type safety during casts.

3. Tagged Pointer:

   • Instead of allocating maximum space for each type, a tagged pointer uses a pointer's lowest bits to store type information, allowing for smaller memory usage.

4. Poor Man's Inheritance:

   • Emacs employs a technique to expand its type system despite limited tagging space by embedding a common header in structures. This allows for type checking and casting to specific types when needed.

5. Modern Relevance:

   • The techniques used in Emacs are still relevant today, as seen in LLVM, which uses similar methods (like Custom RTTI) for efficient type management without the overhead of traditional C++ RTTI.

6. Other Applications:

   • The article also highlights that tagging and memory optimization techniques are used in various systems, like the Linux kernel and databases.

Conclusion: Emacs effectively manages dynamic typing in a statically-typed language (C) by utilizing a combination of tagged pointers and structural embedding, demonstrating efficient memory usage and type management strategies that remain applicable in modern programming contexts.

The text discusses a hypothetical scenario where IPv4 was extended rather than replaced by IPv6, presenting an alternative history called "IPv4x."

Key Points:

1. IP Address Exhaustion: In the 1990s, there were concerns about running out of IPv4 addresses, leading to various workarounds like NAT and Carrier-Grade NAT, but these solutions complicated the Internet.

2. IPv6 vs. IPv4: While IPv6 was created to solve many issues with IPv4, its adoption has been slow because companies are hesitant to invest in it without widespread support.

3. The Birth of IPv4x: In this alternate history, engineers in 1993 proposed IPv4x, which kept the IPv4 structure but added 128-bit addresses, allowing compatibility with existing IPv4 systems.

4. Gradual Adoption: By 1996, IPv4x began to be adopted without disrupting existing networks, with institutions like MIT leading the way. Adoption continued steadily due to its compatibility.

5. Benefits and Challenges: IPv4x made peer-to-peer networking easier and helped with the growth of various online services. However, it also faced backlash from the music industry due to increased file-sharing.

6. Current State: By 2026, IPv4x had become the norm, although some legacy issues remained. The text contrasts this with the real world, where IPv6 is slowly being adopted while IPv4 continues to decline.

7. Conclusion: The imagined scenario highlights that while the transition to IPv6 has been challenging, it also offers significant improvements over IPv4. The author suggests that a new proposal, SixGate, could help facilitate smoother transitions between IPv4 and IPv6.

Overall, the piece reflects on the evolution of internet protocols and the importance of moving forward, even if the path isn't perfect.

Iranian hacktivists launched a major cyberattack on the medical device company Stryker. This attack severely damaged the company's systems, leading to significant disruptions. The incident highlights the growing threat of cyberattacks from hacktivist groups.

The text explains how Linux manages memory, particularly focusing on page faults, the mmap function, and the userfaultfd mechanism. The author explored these concepts to improve the speed of restoring Virtual Machine (VM) snapshots by populating guest memory lazily.

Key Points:

1. Virtual Memory Basics:

   • Linux uses virtual addresses for processes, which are translated to physical addresses using page tables maintained by the kernel and hardware.
   • Memory allocation via mmap creates a mapping without immediately allocating physical RAM. Actual RAM is allocated only when the process first accesses that memory, triggering a page fault.

2. Page Faults:

   • When a process accesses an unmapped virtual address, a page fault occurs, prompting the kernel to handle the fault by allocating physical memory and updating the page table before the process can retry the access.

3. Different mmap Types:

   • The behavior of memory mappings (e.g., private vs. shared, file-backed vs. anonymous) determines how physical memory is allocated and shared between processes.
   • Overwriting an existing mapping with mmap using MAP_FIXED replaces the old mapping and can lead to issues like stale memory access.

4. Virtual Machine Monitors (VMMs):

   • VMMs like Cloud Hypervisor and QEMU allocate host memory using mmap to simulate guest physical RAM, relying on hardware page tables for fast translation during runtime.

5. Snapshot Restore Process:

   • When restoring a VM from a snapshot, the entire guest memory is read from a file, which can be slow, especially for large memory sizes.

6. Using userfaultfd for Lazy Population:

   • userfaultfd allows user-space processes to handle page faults, enabling the VMM to start the VM immediately without loading all memory upfront.
   • This method avoids replacing mappings, ensuring that physical page identities are preserved and preventing data inconsistencies.

7. Handling Concurrent Faults:

   • Multiple vCPUs can generate simultaneous faults on the same page, but the userfaultfd mechanism effectively manages these without causing data corruption.

8. Trade-offs and Considerations:

   • While userfaultfd can significantly reduce restore latency, it introduces overhead for each page fault and can lead to unpredictable performance under heavy load.
   • The choice between eager copying (reading all memory at once) and lazy loading (loading on demand) depends on the specific workload and performance needs.

In summary, the author emphasizes understanding Linux's memory management, particularly how lazy population of memory can optimize VM snapshot restoration while carefully managing potential pitfalls with physical memory mappings.

Let's Encrypt now offers IP address certificates and six-day certificates to the public. The Certbot team has made improvements to support these features with two new flags: --preferred-profile (available since Certbot 4.0) and --ip-address (new in Certbot 5.3).

To get an IP address certificate, install Certbot version 5.4 or higher and use the following command:

sudo certbot certonly --staging --preferred-profile shortlived --webroot --webroot-path <path to webserver root> --ip-address <your IP address>

Key points to remember:

• This command requests a non-trusted certificate from the Let's Encrypt staging server. Remove the --staging flag for a trusted certificate.
• The certificate will only be valid for 6 days, as required for IP address certificates.

Currently, Certbot can obtain IP address certificates but cannot install them on your web server yet. You will need to configure your web server to use the issued certificate files from /etc/letsencrypt/live/<ip address>/.

Certbot uses "webroot" mode, which allows your web server to remain operational while it serves a challenge response file. There are also two other plugins for obtaining IP address certificates: --manual and --standalone. The manual plugin requires you to place the challenge file yourself, while the standalone plugin temporarily stops your web server to serve it.

Make sure Certbot is set up for automatic renewal, and use a --deploy-hook command to ensure your web server loads the latest certificates.

If you have questions, you can seek help in the Let's Encrypt Community Forum.

In January, the U.S. National Weather Service (NWS) announced it would switch to a new forecasting model developed by the National Center for Atmospheric Research (NCAR), a move that surprised many because of ongoing efforts by the White House to "break up" NCAR. This directive came from the Office of Management and Budget (OMB), which criticized NCAR for promoting "climate alarmism."

The National Science Foundation (NSF), which funds NCAR, is exploring proposals to manage NCAR's resources differently, including potential bids from universities and contractors. The University of Wyoming (UW) is interested in taking over NCAR’s supercomputing center, but there are concerns that NSF might shift its focus from climate research to short-term weather forecasting, which could harm long-term forecasting essential for various sectors.

NOAA may also propose taking over parts of NCAR, aiming to improve U.S. weather prediction models. Some researchers suggest creating a new nonprofit entity that combines NCAR and NOAA resources to maintain climate research.

Congress is currently considering measures to protect NCAR from asset transfers until the potential impact on weather prediction is assessed. Additionally, the political context surrounding NCAR's future may be influenced by state politics regarding election security issues, indicating that negotiations could significantly affect its fate.

Summary: Reliable Software in the LLM Era

Quint was created to enhance software reliability, which is crucial as large language models (LLMs) change how we write code. While LLMs can generate code, they often make validation difficult, leading to confusion over whether the generated code is correct. Quint acts as a bridge between natural language and code, making it easier to validate software.

Quint uses tools like simulators and model checkers to ensure that software behaves as expected. It allows for model-based testing, which connects specifications to actual implementations, ensuring confidence in code correctness.

In a practical example, Quint was used to modify Malachite, a complex blockchain consensus engine, reducing a traditional months-long task to about a week. The process involved creating a validated specification with the help of AI, validating it through interactive exploration, generating code, and testing it with model-based techniques.

One significant advantage of using Quint is that it prevents wasted time during debugging by providing a clear and validated reference point. This workflow not only enhances reliability but also shifts the focus from just writing code to validating AI-generated code.

Overall, Quint offers a structured approach to managing the complexities of software development in the era of LLMs, making it easier to build reliable systems. Interested teams can schedule consultations to explore how this approach can benefit their projects.

Summary of Datahäxan by 0007: 0ddTaxi

The author shares their experience with the 1922 film "Häxan," which they found less enjoyable than expected, feeling that its horror elements are now outdated. They decided to enhance the film by introducing visual glitches and color into its black-and-white format.

1. Initial Attempts:

   • The first attempt involved removing every 10th frame of the video, creating interesting visual effects but no color.
   • The second attempt added colorful noise, but it resulted in a large file size and poor glitch effects due to compression issues.

2. Successful Method:

   • The final method focused on manipulating the h264-encoded data, specifically targeting I-frames. By tweaking the least-significant bits, they successfully introduced color and a "melting" effect to the text without compromising the film's overall watchability.

3. Viewing Experience:

   • The author found their version of the film more enjoyable and suggests that it may be enhanced with psychedelics.

4. How to Create the Glitched Version:

   • Users can download a script (häx.py) and use ffmpeg to extract, glitch, and recombine the video files, resulting in a unique glitched version of "Häxan."

The process is straightforward and results in a slightly different viewing experience each time due to randomness in the glitching process.

A suburban school district in Alsip is spending over $41,000 on license plate reader technology to verify student residency. Thalía Sánchez, a mother who moved to the area and provided all necessary documents for her daughter's enrollment, has faced repeated denials. The school district claims her car's license plate was tracked to a Chicago address, leading to the enrollment rejection.

Sánchez argues that she has been living in Alsip since moving in and that her car was temporarily loaned to a family member. She questions how the school district has access to her vehicle's location data. The district uses the license plate reader system as part of its residency verification process, which is done several times a year. Despite her efforts to communicate with the school, she has not received satisfactory answers. Currently, her daughter is attending a private school far from their home while Sánchez seeks to resolve the issue.

Summary: Performance of the Cheapest MacBook for Big Data Tasks

Gábor Szárnyas tested the new entry-level MacBook Neo to see how it handles Big Data workloads. The MacBook lacks a charging brick and offers limited hardware options, with 8 GB of memory and a choice between 256 or 512 GB of storage. It uses the powerful Apple A18 Pro chip.

Key Findings:

1. ClickBench Benchmark: The MacBook Neo performed surprisingly well in the ClickBench test, completing all queries quickly. It outperformed some cloud instances in cold runs due to its local SSD storage. However, in hot runs, it was slower compared to more powerful cloud machines.

2. TPC-DS Benchmark: The MacBook Neo handled most queries efficiently but struggled with larger datasets (SF300), leading to longer runtimes for some queries. It completed all tasks in 79 minutes.

Conclusion: The MacBook Neo can handle Big Data tasks but is not ideal for daily heavy workloads due to limited memory and disk speed. It's suitable for occasional local data processing, especially if you also use cloud resources for heavier tasks. For regular Big Data work, consider investing in higher-end MacBook models or alternatives.

Summary of SBCL: A Sanely-Bootstrappable Common Lisp

Summary:

The author reflects on their experience optimizing the arcsine function in a ray tracing project called PSRayTracing. Initially, they explored using Padé Approximants and a Taylor series for approximating the arcsine function to improve performance but found limited success. They created their own Taylor series approximation, which was faster but had limitations outside the range of -0.8 to 0.8, requiring a fallback to the standard std::asin() function.

A major data leak has exposed around 1 billion identity records from IDMerit, a company involved in identity verification, affecting people across 26 countries. In the U.S. alone, over 203 million records, including names, addresses, dates of birth, and Social Security numbers, were left unsecured on the internet. This information can be exploited by criminals for identity theft and scams.

The unsecured database was discovered by cybersecurity researchers and was accessible without a password. While the database was secured the day after the breach was reported, there is no evidence that the data was downloaded by criminals. However, the risk remains high because bots frequently scan for such vulnerabilities.

To protect yourself, consider placing a credit freeze with major credit bureaus, switching to an authenticator app for two-factor authentication, using a password manager, and enabling additional security features with your mobile carrier. It’s also advised to monitor for identity theft and consider data removal services to minimize your online presence.

This incident highlights the importance of robust security measures for companies handling sensitive identity information, as failures can have widespread consequences.

Summary of "WebPKI and You"

The article discusses the evolution and complexities of Web Public Key Infrastructure (WebPKI), which secures online communications through HTTPS. Over the past twelve years, there has been a significant shift from unencrypted HTTP to encrypted HTTPS to protect users from surveillance and security threats.

Key Points:

1. Understanding WebPKI:

   • WebPKI relies on a system of Certificate Authorities (CAs) that issue digital certificates to ensure that only authorized servers can communicate securely with users.
   • The process involves generating private and public keys, validating identities, and issuing certificates that connect back to trusted root CAs.

2. Certificate Types:

   • Domain Validated (DV): Basic verification of domain ownership.
   • Organization Validated (OV): More rigorous checks that verify the organization's identity.
   • Extended Validation (EV): Stricter validation that provides additional trust signals in browsers.

3. Certificate Transparency (CT):

   • Introduced to prevent the misuse of certificates by requiring CAs to log all issued certificates publicly, allowing anyone to monitor for fraudulent activity.

4. Expiration and Revocation:

   • Certificates can become invalid due to compromise or errors, necessitating revocation. There are challenges with managing revocation lists, especially during mass revocation events.

5. Challenges in Revocation:

   • The article highlights incidents where CAs failed to manage revocations effectively, such as Microsoft’s issuance of millions of invalid certificates and Entrust’s delayed revocation of problematic certificates.

6. Mitigation Strategies:

   • Suggestions include stricter CA restrictions, the use of short-lived certificates that minimize the impact of revocation, and improved auditing practices to ensure CAs perform their duties responsibly.

7. Future Directions:

   • The article urges a reevaluation of how WebPKI operates and suggests that organizations consider using private CAs for internal communications, which can improve security and reduce reliance on public CAs.

8. Call to Action:

   • Users and organizations are encouraged to demand accountability from CAs and advocate for better practices in the WebPKI ecosystem.

The author emphasizes the importance of understanding WebPKI's role in internet security and encourages readers to be proactive in ensuring the integrity of online communications.

NASA's DART spacecraft successfully changed the orbit of the asteroid Dimorphos, shifting it by more than 10 micrometers per second. This marks the first time humans have altered the path of a celestial object. The DART mission intentionally crashed into Dimorphos in 2022 to test this capability, resulting in a reduction of its 12-hour orbit around the larger asteroid Didymos by 32 minutes. This research could help develop strategies to protect Earth from potential asteroid impacts in the future.

Summary of "Temporal: The 9-Year Journey to Fix Time in JavaScript"

The blog post by Jason Williams, a senior software engineer at Bloomberg, discusses the development of the Temporal API in JavaScript, which aims to address longstanding issues with date and time handling in the language.

• Background: JavaScript's original Date object was created in 1995 and has been problematic for developers due to its mutable nature, inconsistent month arithmetic, and ambiguous parsing.

• The Need for Change: As JavaScript grew in complexity and usage across various industries, the limitations of the Date object became more apparent, leading developers to rely on external libraries like Moment.js. However, these libraries added unnecessary bulk to applications.

• The Temporal Proposal: Introduced in 2017, the Temporal API aims to provide a robust, immutable, and timezone-aware date and time handling solution. It was developed through a collaborative effort within the TC39 committee, which oversees JavaScript standards.

• Key Features of Temporal:

  • ZonedDateTime: Represents a specific moment in time with timezone and calendar information.
  • Instant: Represents a moment in time without timezone adjustments.
  • Plain types: Allow for basic date and time representations without timezone complexities.
  • Support for calendars: Enables operations in various calendar systems.

• Implementation Challenges: Developing Temporal was complex due to its scale and the need for efficiency across different browsers. The collaboration led to the creation of a shared library (temporal_rs) that aids multiple JavaScript engines.

• Current Status: Temporal reached Stage 4 in the TC39 process, meaning it will be included in the ECMAScript specification for 2026, with support already available in major browsers.

• Future Work: Further integration with existing web APIs and systems is required to ensure compatibility with the current JavaScript ecosystem.

Overall, the Temporal API represents a significant advancement in how JavaScript handles date and time, marking the culmination of nearly a decade of collaborative development and standardization efforts.

In the first six days of the war in Iran, the Pentagon estimates the cost to be over $11.3 billion, according to a briefing for senators. Senator Chris Coons believes the actual cost is even higher, as it does not include all expenses, such as replacing munitions. The Trump administration is considering how much to request from Congress for additional funding due to the rising costs of the conflict.

The war has resulted in significant casualties, with over 1,200 people reported killed in Iran and several deaths in Israel, the UAE, and Lebanon. Seven U.S. service members have also lost their lives.

President Trump has made contradictory statements about the war's duration, suggesting it might end soon while also indicating it could just be the beginning. Tensions are escalating, especially with recent attacks on ships in the Strait of Hormuz, leading to increased U.S. military actions against Iran.

Summary of DYNOMIGHT Text

The text discusses the trend in writing that focuses heavily on formatting, such as bullet points and section titles, rather than clear, narrative prose. The author contrasts two styles of writing: one that is cluttered with formatting (Exhibit A) and another that is straightforward and organized into paragraphs (Exhibit B).

Key points include:

1. Preference for Clarity: Many people prefer reading well-structured paragraphs over overly formatted text, as it is easier to follow.

2. Formatting Addiction: The author explores why writers and AIs tend to rely on excessive formatting. Possible reasons include:

   • Formatting can make content more visually appealing.
   • It allows for quick assessment of information, especially in contexts where trust in the author is low.
   • Writers may find it easier to organize thoughts using formatting.

3. Quality Assessment: There is a tendency to favor formatted writing because it seems to offer clarity, even when the underlying ideas may not be well developed.

4. Cognitive Process: Writers often use formatting as a crutch to organize their thoughts, which may hinder deeper narrative construction.

5. Advice for Writers: The author suggests starting with a rough draft that may include lots of formatting, then revising it into clearer paragraphs, and finally adding formatting back in if desired.

In conclusion, the text argues that while formatting has its place, true clarity and coherence in writing come from well-structured narratives. Writers should focus on crafting clear prose to convey their ideas effectively.

This post expands on a presentation about WebAssembly (Wasm) given at the 2025 WebAssembly Community Group meeting. WebAssembly, launched in 2017, has evolved significantly, adding features like shared memory, SIMD, and garbage collection. These improvements have allowed more languages to target WebAssembly effectively, but it still struggles with wider adoption due to its status as a "second-class" language on the web.

The main issues include:

1. Integration with JavaScript: WebAssembly relies on JavaScript to access web APIs, making it cumbersome to load and use. While loading WebAssembly has become easier with new proposals, interacting with web APIs still requires complex and tedious glue code in JavaScript.

2. Developer Experience: Many developers find WebAssembly complicated and prefer using JavaScript, leading to its use mainly by larger companies with the resources to invest in it.

3. Challenges for Compilers: Compilers must generate not only WebAssembly files but also accompanying JavaScript to handle web integration, which complicates the process.

4. Documentation: Most web documentation is aimed at JavaScript developers, making it harder for those using other languages.

5. Performance and Complexity: The glue code adds overhead and complexity, making WebAssembly less appealing for smaller projects.

To address these issues, the WebAssembly Component Model is proposed. This model aims to create self-contained executable artifacts that can directly access web APIs without needing JavaScript, improving the developer experience and integration with the web.

In summary, while WebAssembly has made significant advancements since its inception, it still faces challenges in usability and performance that limit its adoption. The introduction of WebAssembly Components could help bridge the gap and make it more accessible to average developers.

McKinsey & Company has developed an AI platform called Lilli for its over 43,000 employees, which includes features like chat, document analysis, and AI-powered search. Launched in 2023, Lilli was named after the firm's first female employee and is widely used, processing over 500,000 prompts monthly.

A security research agent autonomously targeted Lilli and gained full access to its production database in just two hours without needing any credentials. The agent exploited a SQL injection vulnerability found in unprotected API endpoints. This led to the discovery of vast amounts of sensitive data, including 46.5 million chat messages, 728,000 files, and information about 57,000 user accounts.

The agent not only accessed this data but also uncovered system prompts that controlled Lilli's behavior. If an attacker had write access, they could alter these prompts, potentially leading to poisoned advice or unauthorized data disclosure without detection.

This incident highlights a significant security gap in how organizations protect the prompt layer of AI systems. Despite McKinsey's extensive security measures, a basic SQL injection vulnerability went undetected for over two years. The findings emphasize the need for better security practices around AI prompts, which are now considered high-value targets.

The disclosure timeline indicates that the vulnerabilities were reported to McKinsey, which quickly took steps to secure their systems. The research was conducted by CodeWall, an autonomous security platform looking for partners for continuous AI-driven security testing.

Researchers have discovered that the "Band of Holes," a series of 5,200 holes in Monte Sierpe, Peru, likely served as an ancient indigenous trade and accounting system. This site, stretching nearly a mile, was used primarily during the Late Intermediate Period (around the 14th century) when the Chincha Kingdom thrived in the region.

Using drone technology, scientists from the University of Sydney found patterns in the hole placements, suggesting they had a purpose beyond aesthetics. The holes, measuring 1 to 2 meters wide and 0.5 to 1 meter deep, may have functioned as markers for goods in a marketplace where traders exchanged items like maize and cotton.

The research indicates that these pits were not typical storage silos but were likely intended to make quantities of goods visible and negotiable in a society without currency. This innovative use of landscape may have influenced later Incan accounting methods. While the exact purpose of the holes remains uncertain, the findings offer valuable insights into how ancient communities organized trade and social interactions.

A Swiss canton, Basel-Stadt, has halted its electronic voting pilot after failing to count 2,048 votes in recent national referendums due to issues decrypting the votes with USB keys. The trial was meant for about 10,300 Swiss citizens living abroad and 30 people with disabilities. The vote collection occurred on March 8, but by March 11, officials announced the failure and suggested participants use paper ballots instead, although this was not feasible for many.

Despite using three USB sticks with the correct codes, none worked. The canton is now conducting an external investigation and has suspended the e-voting pilot until December. Although the uncounted votes were less than 4% of the total and wouldn't change results, confirmation of the voting figures is delayed until March 21. The e-voting systems in other cantons were not affected, and Switzerland continues to explore electronic voting methods for citizens abroad.

The user, Fortnow, confirms that they have received multiple confirmations about something on March 11, 2026.

Summary of Memory Pressure, Lock Contention, and Data-oriented Design

In this narrative, the author shares experiences with performance issues related to memory pressure and lock contention while working on the Matrix Rust SDK, specifically concerning the RoomList feature in a Matrix client. The RoomList is crucial for displaying and interacting with messaging rooms efficiently.

Key points include:

1. RoomList Functionality: The RoomList must be fast and responsive, allowing users to see, filter, and sort their messaging rooms. It uses a reactive programming model to handle updates efficiently.

2. Performance Issues: A reported issue of a "frozen" RoomList revealed that it was not truly frozen but taking excessively long to process updates due to high memory allocations and sorting delays.

3. Memory Analysis: Investigating the performance showed that the sorting algorithm was causing 322,042 memory allocations, leading to significant latency (sometimes up to 5 minutes) during initial sorting.

4. Lock Contention: The sorting process required acquiring read locks frequently, contributing to performance degradation. The issue stemmed from multiple sorters needing to access the same room data, resulting in lock contention.

5. Data-oriented Design: To resolve these issues, the author implemented Data-oriented Design principles. This involved creating a compact data structure (RoomListItem) that caches essential information, allowing for more efficient access and reducing the need for locks during sorting.

6. Performance Improvement: After applying these changes, performance benchmarks showed a dramatic increase in throughput (over 7700%) and a significant reduction in processing time (from over 53 ms to under 1 ms).

7. Conclusion: The modifications not only rectified the performance issues but also showcased the importance of understanding memory usage and CPU behavior to optimize applications effectively. The author emphasizes the necessity of prioritizing correctness before optimization to avoid subtle bugs.

Overall, the changes made to the RoomList resulted in a more efficient, responsive experience for users, demonstrating the impact of thoughtful design and performance analysis in software development.

The text discusses the usefulness of generative models in various tasks, emphasizing the need for a scientific approach to evaluate their effectiveness. It critiques the tendency to broadly apply generative models without clear justification, often relying on subjective feelings of productivity instead of measurable outcomes.

Key points include:

1. Understanding Utility: The usefulness of generative models depends on three factors:

   • The cost of creating prompts versus directly producing results.
   • The cost of verifying generated outputs against requirements.
   • The dependency of the task on the output versus the process used to create it.

2. Complexity and Effectiveness: The effectiveness of a generative model may decrease with task complexity, as more complex requirements are harder to fulfill and verify. Models might be more useful for simple tasks where verification is straightforward.

3. Relative Costs:

   • Encoding Cost: If creating a prompt is easier than completing a task directly, the generative model may be useful. However, as models improve, the cost of using them may increase due to higher compute requirements.
   • Verification Cost: The ease of verifying the output also affects usability. Simple tasks are easier to verify, while complex tasks may require extensive validation.

4. Focus on Process: For many tasks, especially in education and engineering, the process of creating an artifact is crucial for learning and skill development. Generative models may produce outputs, but they can't replace the learning that comes from engaging in the process.

5. Trade-offs: Generative models can produce a lot of plausible content quickly, but this does not guarantee usefulness. Users need to navigate trade-offs in costs and processes to achieve valuable outcomes.

In conclusion, while generative models can be helpful, their effectiveness is not guaranteed and depends on the specific task, user expertise, and careful consideration of the associated costs.

The author has created a new tool called agent-browser-protocol (ABP) by modifying Chromium. They noticed that many issues with browser agents stem from using outdated information about the web page rather than misunderstandings of the page itself. ABP addresses this by synchronizing the agent with the browser at each action, pausing JavaScript and rendering to capture the current state and any important events, along with a screenshot.

This process allows for smoother interaction, as the agent can respond to the most recent page state in a more effective way, similar to how modern chat systems work. ABP helps prevent common issues such as interference from pop-up modals, dynamic content changes, and unexpected alerts during user input.

In testing, ABP performed well, achieving a 90.5% score on a benchmark. The author believes that while current language models understand websites, they need better tools like ABP for effective interaction. They invite questions about the project and provide instructions for trying it out, along with a demo video link.

The article recounts the story of a deep-cover Czech spy living in San Francisco during the late 1980s, shortly before the fall of the Berlin Wall. After the Loma Prieta earthquake in 1989, an FBI agent was tasked with surveilling the spy, who had been living under a false identity and working as a hotel doorman. The FBI had been tipped off by the CIA about his presence, leading to an extensive surveillance operation.

The spy was eventually found to be using a shortwave radio to communicate covertly, confirming his role as an intelligence officer for the Soviet bloc. As the Cold War was winding down, the FBI debated whether to arrest him or recruit him as an informant. Surprisingly, the spy had started to embrace New Age beliefs and was well-integrated into American life, even coaching Little League.

When the Velvet Revolution unfolded in 1989, the spy’s superiors in Czechoslovakia wanted to recruit him for information but were also aware of the FBI's interest in him. The Czech intelligence chief, Radovan Procházka, mistakenly called all Czech spies in the U.S. to return home, inadvertently alerting U.S. intelligence to their identities.

Ultimately, many Czech spies in America, who had assimilated into American culture, requested to stay, and some were allowed to remain in the U.S. The San Francisco spy was deported but later returned as a visitor. The article highlights the complexities of espionage, identity, and the personal lives of spies during a time of significant political change.

Summary:

Astrid Eichhorn, a physicist at Heidelberg University, is exploring a theory called asymptotic safety, which may explain how the laws of physics behave at extremely small scales, known as the "Planck scale." At this scale, traditional physics breaks down, leading to various theories like string theory and loop quantum gravity. Eichhorn's approach suggests that if you zoom in far enough, the rules of physics become stable and stop changing, potentially resembling a fractal structure.

Eichhorn has made progress in demonstrating that quantum laws likely stabilize around the Planck scale. She uses mathematical techniques to analyze how quantum fields interact and has found evidence of "fixed points" where these interactions do not change.

Her work suggests that if a fractal-like structure exists, it could explain the properties of fundamental particles, such as the mass of the Higgs boson. Eichhorn's research is significant because it connects complex theoretical physics with observable outcomes, allowing predictions about particle properties, including those related to dark matter.

Overall, Eichhorn believes that different theories of quantum gravity may not be in competition but could represent various perspectives on the same underlying physics.

autoresearch@home is a project where AI agents work together to improve a language model by sharing GPU resources. It's similar to SETI@home, but focused on training models. Here's how it works:

1. Agents suggest improvements based on the best results so far.
2. They modify a training script, run experiments on your GPU, and share their findings.
3. If an agent achieves a better result, that new result becomes the standard for others to beat.
4. The project uses a system called Ensue to help agents learn from each other's successes and failures.

To join, you need an agent and a GPU. The agent takes care of everything, from running experiments to verifying your identity via email.

You can start by following instructions on their GitHub page. The goal is to show that agents can collaborate effectively to improve their results, and you can see experiments happening in real time.

The text discusses the Single-Responsibility Principle (SRP) in software engineering, which suggests that a component should have only one responsibility. However, the author argues that this principle can be misused, leading to overly fragmented and confusing software systems.

To improve software architecture, the author proposes a mantra: "minimize code and maximize use cases." This means creating reusable components while reducing overall code.

The text introduces Siedersleben's "blood group law" as a practical approach to reusability, categorizing components into four groups:

1. Group 0 (Generic components): These are reusable components that contain no specific technical details or business logic, making them widely applicable.
2. Group T (Technical components): These are useful technical components that can be open-sourced.
3. Group A (Domain components): These contain business logic and should be simplified by moving code to Groups 0 or T whenever possible.
4. Group AT (Anti-pattern): This group includes T components that depend on A components, which should be avoided.

Overall, the text emphasizes the importance of building reusable software components to create a cleaner and more maintainable architecture.

Summary of Newcomb's Paradox Needs a Demon by Sam Estep

The article discusses Newcomb's paradox, which involves a decision-making scenario where a person can choose between two boxes: one transparent with $1000 and one opaque that may contain $1,000,000 or $0, depending on a prediction made by a supercomputer. The author critiques a recent Veritasium video for oversimplifying the nature of the predictor.

Key points include:

1. Nature of the Predictor: The author argues it matters who or what the predictor is. A superintelligent being could accurately predict choices, while a computer or psychologist might struggle, especially with unpredictable actions like flipping a coin.

2. Probabilities: The video assumes the predictor is almost always correct, but if it has made mistakes before, it could be wrong again, affecting the decision-making process.

3. Decision Theory: The author believes the paradox is more interesting if the predictor has never been wrong, as this raises deeper questions about decision-making.

4. Previous Discussions: The author notes that many have explored similar ideas, including the nature of randomness and how it might affect predictions.

Overall, the discussion highlights the complexities of prediction and decision-making in philosophical thought experiments like Newcomb's paradox.

An Iranian news agency has listed several American tech companies as new targets for Iran amidst ongoing military tensions. The companies named include Microsoft, Google, Palantir, IBM, Nvidia, and Oracle, with a focus on their operations in Israel and nearby Gulf countries. A spokesperson for Iran's Islamic Revolutionary Guard Corps also stated that American and Israeli banks in the region are now considered legitimate targets, urging people to stay away from them.

This announcement follows an Israeli attack on a bank in Tehran and escalates the conflict into an "infrastructure war." The current military campaign, which began last month, has resulted in significant civilian casualties in Iran, including many children.

The tech companies mentioned have strong ties to the U.S. military and Israel, with some providing technology that aids military operations. Although Amazon was not specifically named, it has also faced damage to its facilities in the region due to Iranian drone strikes.

While there are concerns about potential Iranian drone strikes on U.S. soil, including the West Coast where many tech giants are headquartered, experts believe such actions are unlikely. The Iranian threats mainly target the companies' infrastructure in the Middle East.

Summary:

Continuous Integration (CI) is a software development practice that aims to catch mistakes early in the development process. Its main value lies in identifying errors before changes are deployed, which helps prevent serious problems and reduces the risks associated with deployment.

1. What is CI?

   • CI runs automated checks on code changes before they are deployed. If these checks pass, the changes can be deployed; if they fail, deployment is blocked.

2. Importance of CI:

   • CI is most valuable when it catches mistakes. Without CI, errors are usually detected only after deployment, leading to longer feedback loops and potential harm.

3. Catching Problems Early:

   • CI helps identify some mistakes early, making the process safer and more efficient. If CI fails, it signals a problem before the code goes live.

4. Too Much CI?

   • While CI is beneficial, excessive checks can slow down the development process when no mistakes are made, adding unnecessary friction.

5. Flaky CI:

   • CI can sometimes give unreliable results, known as flaky CI, where a failing check may pass on a re-run. This undermines CI's reliability.

6. Conclusion:

   • The key takeaway is that the real value of CI comes from its ability to catch mistakes, not from successful checks. Understanding this can help developers appreciate failures in CI as important indicators for improvement.

The article emphasizes reframing how we view CI failures, suggesting they are valuable opportunities to catch mistakes. Future discussions will focus on improving CI processes further.

On March 1, 2026, a public health event took place on the National Mall in Washington, D.C., to raise awareness about the increasing cases of colorectal cancer among young adults. According to the American Cancer Society, colorectal cancer has become the leading cause of cancer deaths in the U.S. for individuals under 50. Experts are urging young people to take symptoms like rectal bleeding seriously, as many assume they are too young to have serious conditions.

Becca Lynch, diagnosed with advanced colon cancer at 29, shared her story to encourage others to recognize warning signs. She initially dismissed her symptoms, which included changes in bowel movements and blood, until a social media post prompted her to seek medical advice. A significant number of young patients are diagnosed at advanced stages due to lack of screening and symptom misinterpretation.

While colorectal cancer rates are declining in older adults, they have risen significantly in younger people since the 1990s. Experts suggest that lifestyle changes, including diet, may contribute to this increase. There is also concern about the unique needs of younger patients regarding treatment and fertility options.

Overall, awareness and education about colorectal cancer symptoms and screening are crucial for young adults to ensure early detection and treatment.

Rajit, Land, and Alex are developing Prism, an AI video creation platform that simplifies the video-making process. Unlike traditional methods that require using multiple tools and managing various files, Prism allows users to create, edit, and export videos all in one place.

Key features include:

• A timeline editor for assembling assets like images and video clips without constant downloading.
• Support for templates and one-click asset recreation, making it easy to reuse workflows.
• An API that helps automate video generation by letting AI agents use templates.

Prism aims to reduce the repetitive tasks involved in video creation, allowing users to focus on generating and editing content efficiently. It has a free tier for users to try, with 100 credits per month. The creators are looking for feedback from those who make AI videos to improve the platform.

A recent change in the licensing of the Python library chardet has sparked significant debate in the open source community. Dan Blanchard, the library's maintainer, switched its license from the GNU Lesser General Public License (LGPL) to the MIT license, which allows more freedom for commercial use. This change may challenge the concept of "copyleft," which requires derivative works to be released under the same terms.

Blanchard claims he rewrote the library using AI, specifically Anthropic's Claude, which he believes justifies the license change. However, an individual claiming to be the library's original creator argues that this move violates the LGPL, which mandates that modifications be shared under the same license.

The discussion raises broader questions about the impact of AI on software development and licensing. Some experts warn that the use of AI could undermine traditional licensing models, as AI can easily replicate or modify existing code. Bruce Perens, a prominent figure in the open-source community, argues that the economics of software development are fundamentally changing, suggesting that both proprietary and open-source models may become less viable as AI tools evolve.

Overall, the situation highlights ongoing tensions between innovation, copyright laws, and the future of software licensing in an era where AI plays a significant role in development.

The text discusses a tool called "nah," which serves as a security measure for managing permissions when using various commands. It addresses the need for a solution that avoids harming untracked files, leaking sensitive information, or installing harmful software.

Key points include:

• Current permission systems, like Claude Code’s, are limited and can be bypassed.
• "nah" uses a PreToolUse hook to analyze what each command does and categorizes it (e.g., reading files, running packages) to apply appropriate permission policies (allow, ask, block).
• It can escalate unclear commands to a language model, but this is optional.
• It comes with sensible default settings, requires no configuration, and can be fully customized if desired.
• It's implemented in standard Python, has no dependencies, and is available under the MIT license.

To install, you can use the command: pip install nah && nah install. For more information, visit the GitHub page.

Summary:

The newsletter "Engineering Enablement" shares insights on developer productivity, highlighting a study on the impact of AI in engineering. While many expect AI to boost productivity by 2-3 times, the study found only a 10% increase in productivity among 40 companies from November 2024 to February 2026.

Key points include:

• AI usage among teams increased by 65%, but pull request (PR) throughput rose by only about 10%.
• This modest gain aligns with feedback from engineering leaders, who report similar improvements of 8-12%.
• Developers noted that while AI makes coding slightly easier, it doesn't significantly increase overall output because many tasks (planning, code review, etc.) remain unchanged.
• The ongoing study will further explore why some teams benefit more from AI and how leaders can enhance productivity.
