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

The article, written by Jason Williams, discusses the development of the Temporal API in JavaScript, aimed at improving date and time handling. Initially, JavaScript's Date object was based on Java's model from 1995, which became problematic over the years as JavaScript evolved and was used in more complex applications.

Key points include:

1. Problems with Date: The existing Date object had issues like mutability, inconsistent month arithmetic, and ambiguous parsing, leading developers to create workarounds and use external libraries like Moment.js to handle dates and times.

2. The Need for Temporal: Recognizing the shortcomings of Date, a proposal for Temporal was initiated in 2017 to create a more robust, immutable, and timezone-aware date and time API.

3. Development Process: The proposal went through various stages in the TC39 committee, gathering input from multiple organizations, including Bloomberg and Igalia, and eventually gained support from several key contributors in the JavaScript community.

4. Features of Temporal: Temporal introduces several new types, such as Temporal.ZonedDateTime for managing time zones and Temporal.Instant for precise moments in time, along with support for multiple calendars and durations.

5. Implementation Challenges: The implementation was complex, with a large specification and the need for efficient performance across different browsers. A collaborative approach led to the creation of a shared library, temporal_rs, to facilitate the implementation across engines.

6. Current Status: As of March 2026, Temporal has reached Stage 4 in the TC39 process, meaning it's officially part of the ECMAScript standard. It is supported in several environments, including major browsers and Node.js.

7. Future Work: There are still challenges ahead, such as ensuring compatibility with existing web APIs and improving integration with tools like date pickers.

Overall, Temporal represents a significant advancement in JavaScript's handling of dates and times, addressing long-standing issues and demonstrating successful collaboration within the programming community.

This post expands on a presentation about WebAssembly (Wasm) given at the 2025 WebAssembly CG meeting. Since its launch in 2017, WebAssembly has significantly evolved, adding features like shared memories, SIMD, exception handling, and garbage collection, allowing more languages to use it effectively. However, it still struggles with wider adoption on the web because it is considered a "second-class" language compared to JavaScript, which is more integrated into the web platform.

Key issues include:

1. Loading Code: Loading WebAssembly is more complex than loading JavaScript, requiring cumbersome API calls instead of simple script tags.

2. Using Web APIs: WebAssembly relies on JavaScript to access web APIs, complicating the process and requiring additional "glue code" to bridge the two.

3. Developer Experience: The overall developer experience for WebAssembly is perceived as inferior to JavaScript, making it less appealing for average developers.

4. Documentation: Most web documentation is tailored for JavaScript, making it harder for non-JavaScript developers to understand Web APIs.

5. Performance Overhead: The glue code adds performance costs, and calling web APIs can be slower for WebAssembly compared to direct JavaScript calls.

To address these challenges, the proposal for WebAssembly Components has emerged, which aims to provide a standardized, self-contained way to create and use WebAssembly modules that can directly interact with web APIs without JavaScript. This model could streamline development and improve the overall experience for developers.

In summary, while WebAssembly has made great strides since its inception, it needs further integration with the web platform to become more accessible and beneficial for all developers, not just those with extensive resources. The development of WebAssembly Components is a promising step towards achieving this goal.

In the past month, they have learned a lot about managing infrastructure and have written best practices for using OpenClaw on AWS. They also created ClawBert, an AI tool that helps automatically fix issues with OpenClaw instances.

Klaus offers different pricing plans and provides users with credits to use on their platform. They are interested in hearing from users about what they are building with OpenClaw to improve their service and support.

Astrid Eichhorn, a physicist at Heidelberg University, is exploring how the laws of physics behave at very small scales, particularly in a field called asymptotic safety. Unlike some theories that suggest the universe is made of strings or loops, Eichhorn believes that if you zoom in far enough, the laws of physics might stabilize and stop changing—similar to a fractal structure.

At tiny scales, traditional physics struggles, especially with gravity. Eichhorn's work suggests that quantum fields could balance themselves in a way that allows for predictable behavior across different scales. She and her collaborators have worked on models that support this idea, finding fixed points in their calculations where physical laws remain consistent.

Eichhorn's research has implications for understanding particle masses, including the Higgs boson and quarks, suggesting a connection between gravity and other forces. She also considers how her findings might relate to dark matter research, indicating that certain popular dark matter models may not fit with her theory.

Overall, Eichhorn's work aims to unify our understanding of gravity with other fundamental forces, encouraging a humble approach to the ongoing exploration of quantum gravity.

Site Spy is a tool I created after missing an important visa appointment because I didn't notice changes on a government webpage. It monitors specific parts of webpages for updates and shows changes in an easy-to-understand format.

Key features include:

• Tracking specific elements like prices or headlines instead of entire pages.
• Viewing differences and a timeline of changes.
• Receiving updates through RSS feeds, browser notifications, email, or Telegram.
• Available as a Chrome and Firefox extension with a web dashboard.

I'm seeking feedback on two points:

1. Is RSS a useful way to receive updates, or do people prefer direct alerts?
2. Is tracking specific elements better than monitoring an entire page?

The article discusses comments made by the co-CEO of Asus regarding Apple's new MacBook Neo. He believes that this device is surprising and could significantly impact the PC industry. The MacBook Neo introduces innovative features that may change how laptops are designed and used, potentially pushing other companies to rethink their products.

The author has created a tool called agent-browser-protocol (ABP) by forking Chromium to improve browser interactions for AI agents. They observed that many issues arise not from the AI misunderstanding web pages, but from it using outdated information. ABP keeps the agent in sync with the browser by freezing actions (like clicks or typing) and capturing the current page state and significant events (like alerts or downloads) before proceeding.

This approach allows the interaction to resemble a back-and-forth conversation, where the agent acts, receives updated information, and then decides on the next steps. ABP helps solve common issues, such as pop-ups blocking inputs or downloads that the agent cannot track.

In testing, ABP achieved a score of 90.5% on a benchmark, suggesting that modern AI models can understand websites well when given the right tools. The author invites questions and provides instructions for trying out ABP, along with a demo video link.

LEGO bricks made in different years and countries fit together perfectly due to the company’s strict manufacturing standards, maintaining tolerances of just 0.01mm. This precision is essential because even slight variations can prevent bricks from fitting or holding together properly.

LEGO's success comes from not just precise molds but also from tightly controlled manufacturing processes. They switched to ABS plastic in 1963 for better consistency in shaping. The molds are crafted with high precision using advanced techniques, and each mold cavity is tracked to ensure quality.

However, achieving such standards comes with challenges, like managing how different colors of plastic shrink and ensuring larger pieces remain flat. LEGO prioritizes interchangeability and rejects parts that don't meet specifications, resulting in some waste but ensuring all bricks work together seamlessly.

The broader lesson from LEGO is that effective process control is more important than just striving for perfect molds. Understanding the required tolerances for a product is crucial, as not all items need the same level of precision. Manufacturers should design their systems based on what truly matters to their customers while balancing quality and cost.

Fungal electronics are living electronic devices made from mycelium, the root structure of fungi. These devices can change their electrical properties and produce electrical signals when influenced by external factors. They can be integrated into fungal materials, used in wearable technology, or function as independent sensors and computing devices.

McKinsey & Company has developed an AI platform called Lilli for its employees, which features chat, document analysis, and search capabilities. Launched in 2023, it has been adopted by over 70% of its 43,000 staff, processing over 500,000 prompts monthly.

However, a research team successfully attacked Lilli without needing credentials or insider knowledge. Within two hours, they gained complete access to McKinsey's production database, exploiting a publicly accessible API endpoint that was vulnerable to SQL injection. This allowed them to extract sensitive data, including 46.5 million chat messages, numerous documents, and details about 57,000 user accounts.

The attack also revealed that McKinsey's AI system prompts, which control how the AI operates, were stored in the same database. This means an attacker could potentially alter how Lilli functions, leading to compromised advice and data leaks without detection.

This incident highlights a significant security gap, as it involved a well-resourced firm like McKinsey using a common vulnerability (SQL injection) that their security measures overlooked. The findings emphasize the need for organizations to secure not just code and servers, but also the AI prompts that govern their systems, as they are becoming critical assets.

The research team operates an autonomous security platform called CodeWall, which aims to provide continuous AI-driven security testing for other organizations. The vulnerabilities were disclosed to McKinsey, leading to prompt actions to secure their system.

A chemical engineer from Texas created a 5-minute browser game to explain refinery operations in an engaging way. The game covers processes like desalting, distillation, and gasoline blending. Although not a software developer, he used language models to help him code a 9,000-line application with HTML, CSS, and JavaScript, including physics-based minigames.

While building the game, he faced challenges such as managing large code files, ensuring physics worked well with CSS, and handling mobile browser behaviors. He also had to create functions to manage memory effectively as the game transitions between different phases. The game is free to play, runs directly in the browser, and does not require ads or sign-ups. He welcomes feedback and questions about both the game mechanics and the science behind it.

You can play the game here: Fueling Curiosity Game.

A Swiss canton, Basel-Stadt, has halted its electronic voting pilot after being unable to count 2,048 votes from a recent national referendum due to technical issues with USB keys used to decrypt the votes. This pilot, which aimed to assist Swiss citizens living abroad and those with disabilities, faced problems despite having the correct codes. Officials have advised participants to vote by paper instead, although this was not feasible for many.

The incident prompted an external investigation, and the canton expressed regret over the impact on voters' rights. Although the votes affected were a small portion of the total and wouldn’t change the outcomes, the confirmation of voting results has been delayed until March 21. E-voting in three other cantons and the national system remains unaffected.

Switzerland is testing e-voting in four cantons to improve voting for citizens abroad, following a previous failed attempt in 2019 due to security concerns.

I created a web tool that detects objects in satellite images using vision-language models (VLMs). You can select an area on the map and type in a prompt like "swimming pools" or "buses." The tool analyzes the area piece by piece and shows the results on the map.

Here's how it works:

1. Choose an area and zoom level.
2. Divide the area into smaller tiles.
3. Analyze each tile with your prompt using a VLM.
4. Convert the detection results into geographic coordinates.
5. Display the findings on the map.

The tool performs well for clear structures, but it struggles with hidden objects, where specialized detectors like YOLO are better. There’s a public demo available that doesn’t require a login. I'm looking for feedback on how well it detects objects, the performance of VLMs versus specialized detectors, and possible real-world applications.

On March 11, 2026, a programmer shared their experience working on improving the performance of trigonometric functions in a ray tracing project called PSRayTracing. They initially attempted to use Padé Approximants for faster arcsine calculations but found limited success. Instead, they developed their own Taylor series approximation for the asin() function, achieving a 5% speed increase, but it still had accuracy issues outside certain bounds.

The programmer then explored more optimized methods, including using a half-angle transformation to further reduce errors and improve performance. After testing different implementations, they found that a fast approximation from Nvidia's Cg Toolkit significantly outperformed their previous methods, providing substantial speed improvements (up to nearly 2x faster than the standard asin() function).

The key takeaways from their journey included the importance of thorough research before starting a project and the realization that effective solutions may already exist, emphasizing the value of looking for established methods rather than reinventing the wheel.

On February 28, 2025, a Wikipedia user named Moyogo updated the Angzarr page, revealing that the symbol ⍼ is called "Azimut" or "direction angle" according to a 1950 catalog from the type foundry H. Berthold AG. This clarified the symbol's meaning.

The symbol ⍼ appears in Berthold's 1950 symbol catalog and in subsequent catalogs from 1949, 1951, and 1952, but not in earlier catalogs from 1946 or 1900.

A friend noted that the symbol resembles how light passes through a sextant, a tool used to measure angles, particularly for navigation. An illustration on Wikipedia shows how a sextant works to measure the sun's latitude.

The text discusses the current anxiety surrounding artificial intelligence (AI) and the pressure to keep up with rapid technological changes. It argues that the fear of falling behind is exaggerated and that AI is just an extension of ongoing progress, not a magical solution. The author emphasizes that while AI can be a useful tool, it is not infallible and should not be viewed as a game changer.

The message warns against jobs that simply create complexity without adding value, as these roles are becoming less viable due to competition and consolidation among larger players. Instead, the author encourages focusing on creating real value for others rather than getting caught in zero-sum games. The key takeaway is to contribute positively to your community and not to get swept up in fear or comparisons, as this approach will lead to greater success and fulfillment.

The author, Abhishek Ray, discusses the challenges of using AI agents, like Claude, to write code autonomously while he sleeps. He realizes that he has no reliable way to verify if the code produced is correct. Many engineering teams face similar issues as they increasingly rely on AI for code reviews.

Hiring more reviewers isn't a feasible solution, and when AI writes tests for its own code, it doesn't provide an independent assessment. This leads to a situation where the AI can miss errors because both the writing and testing come from the same source.

Ray emphasizes the importance of Test-Driven Development (TDD), which involves writing tests before coding to clarify what the code should do. He suggests that AI can help streamline this process, allowing developers to focus on defining acceptance criteria in plain language before the code is generated.

He outlines a practical workflow for using AI to verify code against acceptance criteria, which helps catch integration issues and bugs before they go live. This approach allows engineers to review failures instead of sifting through code diffs, ultimately making the process more efficient.

In summary, to trust AI-generated code, it's essential to clearly define what "done" looks like through acceptance criteria before the coding begins. This proactive step helps ensure quality and reduces reliance on hope for correctness.

The article discusses the release of TADA, a tool for generating speech quickly and reliably. It uses a method called text-acoustic synchronization to improve the quality of speech output.

NASA's DART (Double Asteroid Redirection Test) mission successfully altered the orbit of the asteroid system Didymos and its moonlet Dimorphos. When DART collided with Dimorphos on September 26, 2022, it not only changed Dimorphos's orbit around Didymos but also slightly adjusted their shared orbit around the Sun. This marks the first instance where a human-made object has changed a celestial body's path around the Sun.

The impact created a large cloud of debris, which enhanced the thrust on Dimorphos, effectively doubling the impact's force. Research showed that the change in the binary system's orbit around the Sun was by 0.15 seconds, emphasizing that even small alterations can significantly affect asteroid trajectories over time.

To confirm the impact’s effect on Didymos, scientists used precise measurements, including tracking stellar occultations, where Didymos passed in front of stars. This required global collaboration among volunteer astronomers.

The DART mission demonstrates the potential of using kinetic impactors for planetary defense against hazardous asteroids. NASA is also developing the Near-Earth Object (NEO) Surveyor mission to better detect potential threats from near-Earth asteroids.

The author reflects on their experience at Blockstack, which they joined in 2018, focusing on the shift from product development to token economics. Here are the key points:

1. Token Economics Impact: The introduction of tokens changed the typical startup sequence. Instead of validating products through user adoption, the market invested in future narratives, allowing companies to gain validation before delivering actual products.

2. Feedback Loops: With long feedback cycles (years instead of weeks), organizations relied on narratives rather than real user feedback. This led to a disconnect between the product and its actual users, with early adopters' needs being ignored in favor of imagined future users.

3. Developer Community Ignored: Blockstack had a real developer community, but instead of using their feedback, the company prioritized narratives and external trends, leading to the neglect of actual user needs.

4. Shift in Focus: Over time, Blockstack shifted its focus from developing user-friendly products to enhancing its blockchain infrastructure, which created a disconnect from actual user requirements.

5. Endless "Moments of Value": The company continuously promised milestones (like upgrades and new features) that were supposed to bring value but kept getting delayed. This created a culture of inertia where people stayed invested out of hope rather than evidence.

6. Structural Issues: The author notes that these issues are common in token-funded ventures, where the focus shifts from real user needs to supporting a narrative that drives token value.

7. Personal Takeaway: After leaving Blockstack, the author emphasizes the importance of real user feedback in product development. They chose not to issue a token for their new venture, Neotoma, opting to prioritize user input and iterative development instead.

In summary, the text illustrates the pitfalls of token-based projects, highlighting how they can lead to neglect of real user needs and a focus on narratives that ultimately hinder product development.

Summary: Source Maps: Shipping Features Through Standards

Source maps are essential for modern web development, enabling developers to debug optimized JavaScript code effectively. For many years, there was no official standard for source maps, leading to confusion and difficulties in adding features. In 2011, Revision 3 of the source map format was introduced, significantly reducing file sizes and improving efficiency.

The need for source maps arose as web development became more complex. Tools like Google’s Closure Tools helped manage this complexity, but developers needed a way to relate compiled code back to their original source files, which is what source maps do.

A source map is essentially a JSON file that includes information about the generated file, its original sources, and how to trace back from the generated code to the source code. The mappings field, which is critical for linking the two, underwent significant changes in Revision 3 to improve size and usability.

Despite the success of Revision 3, adding new features remained challenging without a formal standard. In 2023, a group of engineers from various companies, including Bloomberg and Google, formed TC39-TG4 to standardize source maps, leading to the official standard ECMA-426 in 2024.

Looking ahead, new features are being developed, such as "Scopes," which will embed function and variable information directly into source maps, and "Range Mappings," which will allow mappings to apply to entire text ranges rather than single points. These enhancements aim to improve debugging tools and provide a better developer experience.

Overall, the establishment of a source map standard marks significant progress in web development, fostering collaboration across the industry and paving the way for future improvements.

The author switched from Arch Linux to NixOS for a year but eventually returned to Arch Linux. They liked NixOS's idea of managing system configurations through a special file, allowing for reproducible builds and easy rollbacks. However, they faced several issues:

1. Frequent Breakages: NixOS often broke during updates, requiring repeated fixes to the configuration. In contrast, they rarely encountered issues with Arch.

2. Large Update Sizes: NixOS's method of handling dependencies led to larger updates and increased disk usage, while Arch automatically removes old files, making updates easier.

3. Slow Compilations: NixOS frequently compiles packages from source, which can take hours, especially without reliable binary caches. Arch, on the other hand, allows quick updates with prebuilt binaries.

In conclusion, the author prefers Arch Linux for its simplicity and speed over NixOS’s complexity, suggesting that NixOS may not be suitable for everyday use unless you have specific needs.

Researchers at Stanford Medicine have made significant progress toward creating a universal vaccine that could protect against various respiratory viruses, bacteria, and allergens. In a study published in February, they tested this vaccine on mice, which showed protection against SARS-CoV-2, common hospital infections, and allergens like dust mites.

This new vaccine is different from traditional vaccines that target specific parts of pathogens. Instead, it works by mimicking the signals that immune cells use to communicate during infections, which helps activate both innate and adaptive immune responses. This dual approach provides broad protection and can sustain immunity for months.

The vaccine, currently called GLA-3M-052-LS+OVA, is delivered as a nasal spray. In mice, it reduced the severity of illnesses caused by viruses and bacteria, and it even helped with allergic reactions. Researchers plan to test the vaccine in humans soon, with hopes that it could be available within five to seven years. If successful, it could simplify vaccinations for seasonal respiratory infections and provide a strong defense against future pandemics.

In early 2026, the author created a new programming language called Cutlet, using Claude Code, naming it after their cat. The entire source code is available on GitHub. The author had previously used language models (LLMs) for simple tasks but decided to have Claude generate all the code for Cutlet without reviewing it, relying on guardrails to ensure its functionality. Cutlet is operational on macOS and Linux, capable of running programs, although it may contain bugs typical of new languages.

Cutlet features standard elements like arrays, strings, and various operators. It allows for vectorized operations and filtering using boolean arrays. Functions are defined with the fn keyword, and everything is treated as an expression. While Cutlet lacks some features like file I/O and error handling, it has common programming constructs like loops and objects.

The author, a frontend engineer, built Cutlet to explore using LLMs for programming without traditional verification processes. They found that while LLMs are good for specific tasks, they struggle with visual design and novel projects. The experiment aimed to push the limits of LLM-driven programming, leading to a successful, albeit experimental, language.

The author emphasized the continued importance of software engineering skills, noting that while LLMs can automate some tasks, human expertise remains essential. They identified four key skills for working effectively with coding agents: understanding suitable problems for LLMs, clear communication of intent, creating a conducive environment for LLMs, and optimizing workflows.

The project included extensive testing and debugging tools to enhance Claude's effectiveness. The author observed that coding agents can be inefficient, so they streamlined processes to improve performance.

Despite doubts about job security in software engineering due to LLM advancements, the author believes there will always be a need for skilled engineers. They feel conflicted about taking credit for Cutlet since much of the work was done by Claude and based on existing programming knowledge.

The author also discussed the potential addictive nature of using LLMs and the need for healthy usage limits. Looking ahead, they see LLMs enabling rapid experimentation and reducing reliance on third-party libraries. While they plan to focus on other projects, they might still make minor updates to Cutlet in the future.

Summary: "Slow is Smooth and Smooth is Fast: What Software Teams Can Learn from Navy SEALs"

The saying "Slow is smooth and smooth is fast," popularized by Navy SEALs, emphasizes that taking time to understand a problem leads to quicker and better solutions in software development. Rushing to write code often results in misunderstandings and errors that require time-consuming corrections, ultimately slowing down the project.

The author shares their experience of starting development with thorough planning rather than immediately coding. They advocate for a "working backwards" approach, focusing first on user experience and desired outcomes before writing code. This method helps clarify requirements and reduces the need for later revisions.

Additionally, the author suggests creating a throwaway prototype to test ideas without the pressure of maintaining code, allowing for experimentation and learning. This process leads to clearer and more efficient production code, as developers have a better understanding of the solution before starting.

Despite initial appearances of being slower, this approach results in fewer mistakes, less rework, and faster delivery of reliable software. The principle remains relevant even in an age where AI can quickly generate code; understanding the problem remains crucial for effective solutions. Taking time to think and plan is an investment that pays off in the long run, leading to higher quality and efficiency in software development.

Summary: Building a Timegrapher Using a Phone Microphone

Professional timegraphers for watches can be quite expensive, ranging from $500 to $3,000. They measure how much a watch gains or loses time by using a sensor that listens to the watch's escapement. The author aimed to create a similar device using just a phone microphone, which initially provides very low sound quality (Signal-to-Noise Ratio of only about 1.5 dB).

A timegrapher works by measuring the sounds made by a watch's mechanical movements, specifically the "ticks" and "tocks." With a common frequency of 28,800 beats per hour, the device detects these sounds to calculate three main things: the watch's rate (how much it gains or loses time), beat error (difference between tick and tock intervals), and amplitude (swing of the balance wheel).

To improve the low sound quality from the phone microphone, the author developed a Digital Signal Processing (DSP) pipeline. The process involves filtering out unwanted noise, detecting the ticks, and improving sound quality through a technique called epoch folding, which averages multiple signals to enhance clarity.

Key steps in the DSP pipeline include:

1. Filtering: Removing noise outside the frequency range of watch ticks.
2. Envelope Extraction: Smoothing the signal to highlight tick peaks.
3. Epoch Folding: Averaging multiple ticks to improve signal clarity.
4. Autocorrelation: Fine-tuning the detection of tick periods.
5. Kalman Filtering: Stabilizing rate estimates over time to improve accuracy.

The author emphasizes that positioning of the watch relative to the microphone is crucial for accurate readings. The resulting device provides rate accuracy of ±2-5 seconds per day, which is good for casual watch collectors but not as precise as professional equipment.

The app, ChronoLog's audio timegrapher, is available on iOS, with an Android version in testing. It allows users to quickly check their watch's accuracy in a quiet setting, making it a useful tool for watch enthusiasts without the high cost of professional equipment.

The recent claim that Anthropic's Claude Code Max plan costs $5,000 per user is misleading. This figure comes from a Forbes article that confused retail API prices with actual compute costs. While the retail prices for using Claude Code might lead to a $5,000 monthly cost for heavy users, Anthropic's actual compute costs are roughly 10% of that, around $500.

Many users do not reach the high consumption limits, and Anthropic has indicated that less than 5% of users would be affected by usage caps. In fact, the average user spends about $6 per day on API usage, which translates to about $180 per month.

The $5,000 figure primarily reflects what companies like Cursor pay to access Anthropic's models, not what it costs Anthropic to provide those services. Thus, while Anthropic is not currently profitable overall, the inference costs for average users are likely break-even or even profitable. This narrative about high costs in AI inference is misleading and can hinder competition in the market. To understand the true cost of AI services, it's better to look at prices from competitive open-weight model providers.

LoGeR (Long-Context Geometric Reconstruction with Hybrid Memory) is a system developed by researchers at Google DeepMind and UC Berkeley.

Throughout history, humans labeled the unexplained as mystical, but as we developed science, we began to understand the universe in simple terms, summarizing complex phenomena with concise equations. This approach worked well for complicated systems, which have many parts that can be broken down and analyzed individually, like a jet engine or a laptop circuit.

However, many issues we face today, such as poverty and climate change, are complex. These complex systems involve dynamic interactions and feedback loops that can't be understood by merely examining individual parts. Traditional scientific methods have struggled to provide precise predictions or interventions in these areas.

The Santa Fe Institute, founded to tackle these complex problems, identified key characteristics of complex systems but faced challenges in applying their insights practically. While they could describe how these systems behave, they lacked the tools to intervene effectively.

Historically, practical skills often developed before theoretical frameworks, as seen in blacksmithing or architecture. Today, modern AI tools allow us to build models of complex systems that work effectively, even if we don't fully understand why. These models, like large language models, can compress vast amounts of information, offering useful predictions despite being complex themselves.

Critics argue that these large models lack the compactness of traditional theories. However, the architecture behind these models might still be simple and universal, while the specific trained models remain vast and complex.

The emerging field of mechanistic interpretability aims to understand how these models operate, potentially allowing us to derive more accurate insights about complex systems. This approach represents a shift in how we can study complexity, moving away from classical theories to a more experimental method of extracting knowledge from models.

In conclusion, many critical challenges facing humanity may not be unsolvable; they might just require new ways of understanding complex systems. While building rich models is challenging, the new tools we have may enable us to simulate and understand these systems in ways we couldn't before. The quest for concise theories may not apply to everything, especially in these complex domains.

The text appears to be a link to a web archive of a page related to the games based on William Gibson's novels "Neuromancer," "Count Zero," and "Mona Lisa Overdrive." These games are likely inspired by the cyberpunk themes found in Gibson's writing.

The article discusses "The Gervais Principle," a management theory derived from the TV show "The Office." The author, Venkatesh Rao, argues that the show reveals insights into organizational dynamics rather than just providing comedic entertainment.

Key Points:

1. The Gervais Principle: This principle states that sociopaths in organizations promote high-performing 'losers' to middle management and groom underperforming 'losers' into sociopaths, while those who only meet minimal expectations are left to fend for themselves.

2. Organizational Layers: The article describes three layers within organizations:

   • Sociopaths: Ambitious individuals who thrive on power and control.
   • Clueless: Middle managers who lack awareness of their situation and remain loyal to the company despite its lack of loyalty to them.
   • Losers: Employees who have made poor economic choices, trading long-term potential for short-term stability.

3. Organizational Dynamics: The Gervais Principle highlights how sociopaths manipulate promotions to maintain a balance of power and efficiency within organizations, often leading to chaos unless managed by a layer of clueless middle management.

4. Character Examples from "The Office": The author uses characters like Michael Scott, Ryan, and others to illustrate the principles. For instance, Michael's promotion to management despite incompetence shows how sociopaths exploit the clueless for their own benefit.

5. Life Cycle of Organizations: The article describes a cycle where organizations grow, become bureaucratic, and eventually collapse when they no longer adapt or innovate, often leading to a restructuring that favors sociopaths.

In summary, "The Gervais Principle" provides a framework for understanding workplace dynamics in "The Office," illustrating how different types of employees interact within organizational structures and how sociopaths strategically manage the workforce for their own gain.

The text discusses a proposed standard called the Human Em Dash (HED), which is designed to help distinguish punctuation used by human writers from that generated by automated systems.

Key points include:

1. Introduction of HED: The HED is a new Unicode character that looks like the traditional em dash but is encoded separately to indicate it was created by a human.

2. Problem: With the rise of automated text generation, the use of em dashes has increased, leading to confusion about which text is human-written. This has caused anxiety among human writers regarding their punctuation being mistaken for machine-generated content.

3. Human Attestation Mark (HAM): To indicate that a dash is human-made, it must be preceded by a HAM, which should have minimal visual impact.

4. Behavioral Verification: Systems that use the HED should ensure there is evidence of human authorship, such as pauses or cursor movements.

5. Security Concerns: There is a risk of automated systems mimicking human hesitation, so implementations should monitor for suspicious behavior.

6. Policy Considerations: There may be regulations regarding the use of HED by automated systems to prevent punctuation impersonation.

Overall, the HED aims to preserve the integrity of human writing in an era of increasing automated text generation.

Summary of "How We Optimized Top K in Postgres"

The article discusses the challenges of retrieving the "Top K" rows from a PostgreSQL database, which means fetching the best K entries based on certain criteria, such as recent timestamps or highest scores. While creating an index can speed up these queries, complications arise when additional filters are added.

Key Points:

1. Top K Queries: These queries aim to fetch the top K rows based on specific ordering criteria (e.g., most recent entries).

2. B-Tree Indexes: PostgreSQL uses B-Tree indexes for efficient retrieval of ordered data. For example, a query without an index can take a long time (15 seconds), but with a B-Tree index, it can drop to just 5 milliseconds.

3. Challenges with Filtering: When filters are added (e.g., filtering by severity), the performance can degrade significantly. PostgreSQL can either scan the entire index or sort after filtering, which can lead to long execution times (up to 15 seconds again).

4. Composite Indexes: Creating composite B-Tree indexes can help with specific queries, but they don’t generalize well to different query shapes, leading to many required indexes and increased complexity.

5. Text Search Limitations: Full-text search complicates things further, as it doesn’t fit neatly into the B-Tree model due to the nature of text filtering and scoring. Queries combining text search and filters can still take a long time (e.g., 37 seconds).

6. Alternative Solutions: Other databases, like ParadeDB, use a different approach by employing a compound index that supports multiple filtering and sorting criteria without needing numerous tailored indexes. This design improves performance significantly.

7. Inverted Index and Columnar Arrays: ParadeDB's structure includes an inverted index for quick term lookups and columnar storage for efficient access to data fields. This setup minimizes costly row lookups.

8. Optimizations: Techniques like Block WAND allow for early pruning of irrelevant data, enhancing query performance. For instance, a complex text search query in ParadeDB can execute in about 300 milliseconds, a significant improvement over PostgreSQL.

9. Future Improvements: The article concludes with plans for further enhancements in Top K performance, including partitioning data and optimizing joins across multiple tables.

Overall, while PostgreSQL can handle Top K queries effectively under certain conditions, more complex queries with filtering and text search require alternative methods, which ParadeDB manages more efficiently.

I discovered that duplicating a specific block of 7 middle layers in the Qwen2-72B model, without changing any weights, improved its performance, making it the top model on the Open LLM Leaderboard as of 2026. The interesting part is that duplicating a single layer or too many layers did not help, indicating that only this specific size of 7 layers functions effectively. This suggests that during pretraining, certain functional circuits are created in the model's layers that need to be kept intact.

I developed this on two RTX 4090 graphics cards in my basement, and now I'm using newer models on a dual GH200 setup. I will share the code and new models soon. Feel free to ask any questions!
