Introducing tmux-rs
(Introducing tmux-rs)

Summary of "Introducing tmux-rs" by Collin Richards

On July 3, 2025, Collin Richards announced a personal project where he has successfully rewritten the tmux codebase from C to Rust. After six months of work, the entire codebase, which increased from about 67,000 lines of C to 81,000 lines of Rust, is now fully in Rust, albeit using unsafe code.

Key Points:

  1. Project Motivation: The project is a hobby, similar to gardening, and there isn't a specific reason for the conversion other than personal interest.

  2. Initial Approach: Collin started with a tool called C2Rust to automate the conversion but found the generated code to be unmanageable. He ultimately decided to manually translate the C code into Rust.

  3. Development Process:

    • Understanding the build process was crucial; he adapted the existing autotools setup to work with Rust.
    • He initially translated files one at a time but later switched to translating one function at a time to facilitate easier debugging.
    • Bugs were encountered during the translation, often due to mismatches between C and Rust types or incorrect function prototypes.
  4. Technical Challenges:

    • Raw pointers in Rust were used due to the limitations of directly using Rust references in the translated code.
    • He addressed the use of C's goto statement using Rust constructs like labeled blocks and loops.
    • He reimplemented a parser originally built with yacc using the lalrpop crate.
  5. Tools Used: His workflow included using Vim with custom macros for efficiency and experimenting with AI tools, although he found they didn't significantly speed up the process.

  6. Future Goals: Although the project is now complete at version 0.0.1, Collin aims to improve the code further by transitioning to safe Rust and addressing existing bugs.

The project is open for others interested in Rust and tmux, inviting feedback and collaboration via GitHub Discussions.

Poor Man's Back End-as-a-Service (BaaS), Similar to Firebase/Supabase/Pocketbase
(Poor Man's Back End-as-a-Service (BaaS), Similar to Firebase/Supabase/Pocketbase)

Pennybase Overview

Pennybase is a lightweight Backend-as-a-Service (BaaS) similar to Firebase and Supabase. It is built with less than 1000 lines of Go code and has no external dependencies. Here are its main features:

  • File Storage: Uses CSV files to store data, keeping track of versions for each record.
  • REST API: Provides a simple API for data access and manipulation, returning JSON responses.
  • Authentication: Supports session cookies and Basic Auth for user authentication.
  • Permissions: Implements role-based access control (RBAC) and ownership-based permissions.
  • Real-time Updates: Offers real-time updates using Server-Sent Events (SSE).
  • Schema Validation: Validates data types and formats for records.
  • Template Rendering: Uses Go templates for serving dynamic HTML content.

How It Works

Data is stored in easily readable CSV files, with each update creating a new version of records. An in-memory index is used for quick access to the latest versions. The CSV structure includes columns for record ID, version number, and data fields.

Users and permissions are managed through special CSV files:

  • _users.csv: Contains user credentials and roles.
  • _permissions.csv: Defines access rules for different resources.

REST API Endpoints

Pennybase provides endpoints for:

  • Listing and retrieving records.
  • Creating, updating, and deleting records (with appropriate permissions).
  • Streaming real-time events.

Static Assets and Templates

Pennybase can serve static files (HTML, CSS, JS) and render HTML templates, allowing dynamic content generation based on user and resource data.

Extensibility with Hooks

Pennybase supports extending its functionality through a hook system that allows custom actions during data modifications.

Contributions

The project encourages contributions, focusing on keeping the codebase small and clear. It is open-source under the MIT license.

Locality of Behaviour (2020)
(Locality of Behaviour (2020))

Locality of Behaviour (LoB)

Locality of Behaviour is the idea that a programmer should be able to understand what a piece of code does by looking at that specific code alone. This principle aims to make code more straightforward and maintainable.

Key Points:

  1. Definition: LoB means that the behavior of a code unit should be clear without needing to examine other parts of the code.

  2. Examples:

    • In htmx, a button's behavior is clear from its tag: <button hx-get="/clicked">Click Me</button>. This satisfies LoB.
    • In jQuery, the button’s behavior is hidden in multiple places, making it hard to understand:
      $("#d1").on("click", function(){
        $.ajax({
          /* AJAX options... */
        });
      });
      

    This shows poor LoB.

  3. Implementation vs. Invocation:

    • There's a difference between showing how something works (implementation) and showing how to use it (invocation). Good functions hide the complex details but still make their use clear.
  4. Conflicts with Other Principles:

    • LoB can sometimes clash with other principles like:
      • DRY (Don’t Repeat Yourself): While avoiding redundancy is important, it can lead to less obvious behavior if used excessively.
      • SoC (Separation of Concerns): Separating different aspects of code can obscure behavior, making it hard to see how changes in one area affect another.
  5. Conclusion: While LoB is important for making code easier to maintain, it should be balanced with other principles. Striving for LoB can lead to better software quality and sustainability.

Spending Too Much Money on a Coding Agent
(Spending Too Much Money on a Coding Agent)

Summary: Spending Too Much Money on a Coding Agent

The author discusses their experience using various coding models, particularly Cursor and Claude Sonnet, for programming tasks. Initially, they found these models useful but became frustrated with their inefficiencies under tight deadlines. They then switched to a new model called o3, which, despite being slower, produced better results.

The author and their co-founder decided to spend $1,000 a month on o3 due to its effectiveness, even though it felt excessive. They discovered that o3 and similar models excelled in several areas, such as using tools effectively, avoiding unnecessary complications, and providing valuable research assistance.

Despite concerns about costs, they found that spending on high-quality coding agents could be justified, especially as prices for these models dropped recently. They outlined strategies to maximize the value from these models, including early error detection, using straightforward technologies, refining coding rules, and enhancing development scripts.

Ultimately, the author believes that using multiple coding agents can significantly improve productivity and allow developers to focus on more complex tasks rather than routine coding. The evolution of these tools suggests a shift towards using them collaboratively for better coding practices.

Parallelizing SHA256 Calculation on FPGA
(Parallelizing SHA256 Calculation on FPGA)

Summary: Parallelizing SHA256 Calculation on FPGA

P. Trujillo developed an SHA-256 hash calculator on an FPGA, which computes the hash of a string in 68 clock cycles. However, the initial design was underutilized because it produced only one hash at a time. To improve performance, the new design includes multiple hash calculators that run in parallel.

Key improvements made to the design include:

  • Storing the K matrix (pre-computed values) at a higher level, allowing all calculators to access it without duplication.
  • Initializing the W matrix values in parallel, which removes the need for a complex interface.

The new module is called sha256_core_pif. A coordinating module, SHA256_manager, was added to manage inputs and outputs for the hash calculators. The system is used for a hash cracker application that tests possible strings against a given SHA-256 hash.

The project runs on a Litefury board connected to a Raspberry Pi 5 and uses a clock speed of 62.5 MHz to meet timing requirements, integrating 12 parallel hash calculators. A Python driver was created to interface with the FPGA, allowing it to read and write data as needed.

The project demonstrates the potential of FPGAs in accelerating cryptographic tasks, which is expected to grow in importance in the fields of cryptography and cybersecurity. All project files are available on GitHub, and the author invites others involved in cryptography to explore FPGA solutions.

About AI Evals
(About AI Evals)

Summary of AI Evals FAQs

This text addresses common questions about AI evaluations, particularly for AI applications, based on insights from a course taught by Hamel Husain and Shreya Shankar.

  1. RAG Usage: "RAG" (Retrieval-Augmented Generation) is still valuable. The claim that "RAG is dead" refers to specific naive uses in coding applications, not the concept itself. Effective retrieval strategies are key for AI performance.

  2. Model Selection: Using the same model for both tasks and evaluations can work, especially for binary classification. Prioritize understanding where your model fails through error analysis before switching models.

  3. Custom Annotation Tools: Building a custom annotation tool is highly recommended as it enhances workflow speed and efficiency. Off-the-shelf tools may not meet specific needs.

  4. Binary vs. Likert Evaluations: Binary evaluations (pass/fail) are often more effective than 1-5 rating scales, as they lead to clearer, quicker decision-making.

  5. Debugging Multi-Turn Conversations: Start debugging by assessing overall success and identifying the first failure point. Simplifying the context can streamline error identification.

  6. Automated Evaluators: Focus on building automated evaluators for persistent issues rather than every failure. Simple checks are often more cost-effective.

  7. Annotation Staffing: For most small to medium organizations, one expert ("benevolent dictator") is sufficient for quality decisions.

  8. Evaluation Gaps: Existing tools may not cover all evaluation needs, especially for error analysis and custom metrics. Be prepared to fill these gaps yourself.

  9. Synthetic Data Generation: Use a structured approach to generate synthetic data, focusing on dimensions that reflect potential failure modes.

  10. Evaluating Diverse Queries: Base evaluation strategies on observed failure patterns rather than trying to classify every query type in advance.

  11. Chunk Size for Document Processing: Choose chunk sizes based on task type—larger chunks for fixed-output tasks and smaller chunks for expansive-output tasks to improve reasoning.

  12. Evaluating RAG Systems: Use traditional information retrieval metrics for the retrieval component and error analysis for the generation component.

  13. Custom Interfaces for Review: Build annotation tools that enhance clarity and speed, allowing for intuitive reviews and efficient navigation.

  14. Budgeting for Evaluations: Treat evaluation as an integral part of development, focusing on error analysis rather than just automated checks.

  15. Error Analysis Importance: Conduct thorough error analysis to identify unique failure modes and guide the development of relevant evaluation metrics.

  16. Guardrails vs. Evaluators: Guardrails prevent immediate errors in real-time, while evaluators assess quality and performance post-response.

  17. Minimum Viable Evaluation Setup: Start with error analysis, using a single expert to guide quality. Utilize notebooks for efficient trace review and analysis.

  18. Evaluating Agentic Workflows: Assess overall task success first, then analyze individual steps to identify failures.

  19. Vendor Selection: Choose evaluation vendors based on support and fit for your needs, as features are often similar.

  20. CI/CD vs. Production Evaluation: CI tests are small and focused on known issues, while production evaluations sample live data and may require more complex assessments.

Overall, the emphasis is on practical strategies for improving AI evaluations, highlighting the importance of understanding failures and tailoring approaches to specific applications.

Importance of context management in AI NPCs
(Importance of context management in AI NPCs)

Summary: Importance of Context Management in AI NPCs

In developing my AI NPC project, I encountered challenges with managing AI context. This aspect is often overlooked but is crucial. To address the growing context issue, I implemented a solution involving frequent summarization and self-growing systems. This allows the AI to remember important details about interactions, creating a more immersive experience where each AI can learn and observe uniquely.

However, as the context increases, its effectiveness decreases, slowing down the AI's response time. I've found that too much context can overwhelm the model, leading it to ignore relevant information. To combat this, I developed a system to keep the AI's context cleaner, preventing it from becoming confused by unrelated messages.

I believe in maintaining a clean context by not overloading the AI with unnecessary information, such as error messages or irrelevant tool use details. This approach improves the AI's performance and keeps it focused.

The term 'Context Engineering' has emerged as a new concept in AI development, which I see as an evolution from 'Prompt Engineering.' While I enjoy working on this for fun, effective context management is essential for creating truly interactive NPCs. It's important to balance context with relevant prompts to enhance the AI's capabilities.

The article discusses the whole-genome sequencing of an ancient Egyptian man from the Old Kingdom, specifically from a site called Nuwayrat, dated between 2855 and 2570 BCE. This individual was buried in a ceramic pot inside a rock-cut tomb, which helped preserve his DNA.

Key findings include:

  • The man's ancestry primarily reflects North African Neolithic origins, but about 20% of his genetic makeup is linked to the eastern Fertile Crescent, including areas like Mesopotamia.
  • This suggests that ancient Egypt had connections with neighboring regions not just through trade and culture but also through human migration.
  • The study contributes to understanding the genetic diversity of early Egyptians, challenging the idea that their population was solely of local origin.

The individual was likely of higher social status, with evidence suggesting he led a physically demanding life despite his elite burial. Genetic predictions indicate he had brown eyes and skin that ranged from dark to black. Additionally, his diet was consistent with typical ancient Egyptian fare, including terrestrial animal protein and plants.

Overall, this research provides valuable insights into the genetic history and connections of ancient Egyptians with surrounding regions during a pivotal time in their civilization.

That XOR Trick (2020)
(That XOR Trick (2020))

The text discusses how to solve certain interview questions using XOR, a logical operator that works on bits. Here are the key points:

  1. XOR Basics: XOR (denoted as ^) returns 0 if both bits are the same and 1 if they are different. It can be applied to various types of values, not just booleans.

  2. Key Properties of XOR:

    • XOR with 0: (x \oplus 0 = x)
    • XOR of the same number: (x \oplus x = 0)
    • Commutative: (x \oplus y = y \oplus x)
    • Duplicate cancellation: A sequence of XOR operations can cancel out duplicates.
  3. Applications:

    • In-Place Swapping: You can swap two variables using three XOR operations.
    • Finding a Missing Number: Given an array of numbers from 1 to n with one missing, you can find the missing number by XORing all numbers from 1 to n with the numbers in the array.
    • Finding a Duplicate Number: The same XOR method can be used to find a duplicated number in an array of n+1 integers containing numbers from 1 to n.
    • Finding Two Missing/Duplicated Numbers: The process can be extended to find two missing or duplicated numbers by analyzing bit differences from the XOR result.
  4. Limitations: The XOR trick works well for one or two missing/duplicated numbers but fails for more than two.

  5. Final Thoughts: While using XOR in interviews may not be ideal due to its specialized nature, the properties of XOR provide elegant solutions to these problems. The author appreciates the beauty and utility of XOR in solving these challenges.

Writing Code Was Never the Bottleneck
(Writing Code Was Never the Bottleneck)

The author argues that writing code has never been the main bottleneck in software engineering. Instead, challenges like code reviews, mentoring, testing, and communication slow down the process more than actually coding does. With the rise of AI tools like LLMs, which can generate code quickly, there's a misconception that coding is now the bottleneck.

However, while LLMs make it easier to produce code, they increase the complexity of understanding, testing, and trusting that code. As more code is generated, the pressure on reviewers and maintainers grows, especially when they struggle to understand the generated code or when it deviates from established practices.

The author emphasizes that the true challenge remains understanding the code, not writing it. Even though LLMs speed up code production, the effort required for reasoning about the code and ensuring quality remains high. Collaboration and shared understanding are still crucial, but faster code generation can lead to assumptions about quality, putting additional stress on teams.

In summary, while the cost of writing code has decreased, the need for thorough review and understanding has not changed, making it the real bottleneck in software development.

The Amiga stood out for its superior graphics and sound compared to competitors like the Atari ST and PC, making it a popular choice among gamers and creatives in the early 90s.

Despite the rise of the PC market and the emergence of games like Doom, the author argues that Doom wasn't the reason for the Amiga's decline. Instead, the Amiga's architecture, which excelled in 2D graphics and multitasking, struggled to compete with the rapidly advancing PC hardware, especially as CPUs became cheaper and more powerful.

As PCs became more affordable and capable of running complex games, the Amiga's limitations became apparent. Commodore's failure to innovate and release a competitive new model contributed to the decline. The Amiga's unique features, like pre-emptive multitasking, were no longer enough to keep it relevant.

The author reflects on their loyalty to the Amiga, even as they eventually transitioned to PCs for gaming and everyday tasks. Despite the Amiga's decline, they still cherish their experiences with it and recognize its impact on the computing landscape. Ultimately, the Amiga's downfall was not just due to a single factor, like Doom, but rather a combination of technological advancements in PCs and missteps by Commodore.

What's the difference between named functions and arrow functions in JavaScript?
(What's the difference between named functions and arrow functions in JavaScript?)

The article explains the differences between ordinary functions and arrow functions in JavaScript, highlighting their syntax, behavior, and when to use each type.

Key Points:

  1. Function Types:

    • Function Declarations: Named functions that are hoisted (available before their declaration) and can be used anywhere in the scope.
    • Function Expressions: Functions defined within an expression, either anonymous or named, that are not hoisted. They must be defined before being called.
    • Arrow Functions: A more concise way to write functions, always anonymous, and do not have their own this, arguments, or super.
  2. Syntax Differences:

    • Arrow functions use => instead of the function keyword and can be shorter when the body has one expression (no curly braces or return needed).
  3. Behavioral Differences:

    • Arrow functions do not bind their own this, which can lead to issues when using them as methods on objects.
    • They cannot be used as constructors (with new) and cannot use the yield keyword, making them incompatible with generator functions.
  4. When to Use Each:

    • Use arrow functions for concise, anonymous callbacks, especially in array methods like .map().
    • Use function declarations or expressions when you need access to this or want to define functions before using them (for readability).

Conclusion:

Choosing between function types depends on your specific needs regarding this context, readability, and whether you are working with generators. Arrow functions are generally preferred for their brevity and simplicity in most cases, while traditional functions offer more flexibility in some scenarios.

(Demonstration of Algorithmic Quantum Speedup for an Abelian Hidden Subgroup)

Simon’s problem involves finding a hidden pattern in a special type of function. This problem is significant because it was one of the first to show that quantum computers can solve certain tasks much faster than classical computers. In this study, researchers used two IBM Quantum processors to show that their quantum algorithm could solve a version of Simon’s problem more quickly when the hidden pattern had specific limitations. They achieved a notable speedup with up to 58 qubits, although it was not as high as the ideal case. The speedup improved when they used techniques to protect against errors and to reduce measurement mistakes. This research demonstrates a clear advantage of quantum computing for solving specific problems.

(Next month, saved passwords will no longer be in Microsoft’s Authenticator app)

Starting this month, Microsoft Authenticator will stop supporting the autofill password function as part of a shift towards using passkeys instead of traditional passwords. Last month, Microsoft also prevented users from saving new passwords in the app. By August 2025, all your saved passwords will be removed, and you'll need to use passkeys—like a PIN, fingerprint, or facial recognition.

Digital security expert Attila Tomaschek explains that passkeys are safer than passwords because they require both a public and a private key for authentication, reducing risks like phishing and identity theft. Using the same password across multiple accounts can be risky, making users vulnerable to scams.

Microsoft Authenticator helps you log into your accounts securely with biometric options, and while passwords can still be stored in Microsoft Edge, it's recommended to transition to passkeys.

A passkey is a secure credential created using biometric data or a PIN, stored only on your device, which eliminates the hassle of remembering passwords. To set up a passkey in Microsoft Authenticator, open the app, tap on your account, and follow the prompts after logging in with your existing credentials.

Recent research shows that audible sound can influence gene activity in mouse cells, potentially leading to medical advancements. A study at Kyoto University found that exposing mouse muscle precursor cells to sound waves for different durations altered the activity of over 100 genes. Many of these genes are involved in cell attachment and movement.

Specifically, the sound increased the attachment sites of cells to surrounding tissues, likely by activating an enzyme called focal adhesion kinase (FAK). Additionally, the sound reduced the development of fat cells, leading to a decrease in fat accumulation by 13 to 15%.

Audible sound is noninvasive and easier to produce than ultrasound, making it a promising tool for treating various conditions, including obesity and cancer. Researchers aim to test these methods in living mice and eventually in humans within the next five to ten years.

A list is a monad
(A list is a monad)

Summary: A List is a Monad (Part 1)

This post discusses the concept of monads in functional programming, emphasizing that they can be seen as containers or contexts for values. Monads allow functions to be reused across different situations without rewriting the control flow logic.

There are two main types of monads:

  1. Monads as Results: These hold already computed values with additional context, like a list or an optional value.
  2. Monads as Recipes: These represent computations that haven't happened yet, like C#'s Task<T>, which holds a promise of future values.

The post focuses on the "Results" category, particularly using lists to illustrate the mechanics of two key operations: Map and flatMap.

  • Map applies a function to each item in a list, transforming it without needing to manually iterate through the list. This allows for cleaner, more declarative code compared to traditional procedural programming.

  • flatMap is used to chain computations that return monadic values, preventing the creation of nested monads.

The post also introduces the Maybe monad, which can hold a computed value or indicate absence. It simplifies the process of checking for null values by incorporating those checks into its operations.

For a type to be a true monad, it must implement two operations (Unit and flatMap) and follow three laws (Left Identity, Right Identity, and Associativity) that ensure consistent behavior when chaining operations.

The overall goal is to show how monads can simplify code by managing control flow and value presence, paving the way for more advanced monadic concepts in future discussions.

Physicists at the Facility for Rare Isotope Beams (FRIB) in Michigan are making progress in understanding how stars create heavy elements, specifically those heavier than iron. By simulating the conditions found in stars, researchers are studying the "intermediate neutron-capture process" (i-process), which is believed to be a third method of forming heavy elements, alongside the known s-process and r-process.

The s-process occurs slowly in red giant stars, while the r-process happens quickly in neutron stars. The i-process is thought to occur in environments that are neutron-rich but do not fit neatly into either category. Scientists at FRIB are conducting experiments that involve accelerating atomic nuclei and smashing them to create unstable isotopes, which helps in determining how these heavy elements are formed.

As they gather data, the researchers are comparing their findings with the elemental compositions observed in ancient stars to validate their models. They aim to discover the origins of precious metals like gold and platinum, which are still not fully understood. The research is expected to yield significant insights into the formation of heavy elements over the next five to ten years.

The article discusses how AI coding assistants can pose security risks and highlights a project by Sharon Brizinov, who scanned GitHub for "Oops Commits" to find leaked secrets. Here are the main points:

  1. GitHub's Commit System: When developers delete commits on GitHub, the commits are not actually removed; GitHub retains a record of them. This means that sensitive information can still be accessed even after it appears to be deleted.

  2. Research Findings: Brizinov discovered that he could access these deleted commits by using GitHub's Event API and the GitHub Archive, which logs all public commit events. He found secrets worth $25,000 in bug bounties by analyzing these deleted commits.

  3. New Tool: Together with Truffle Security, he developed an open-source tool called the Force Push Scanner that helps users detect secrets in these hidden commits.

  4. Impact of Leaked Secrets: The research revealed that many sensitive credentials, including GitHub Personal Access Tokens and AWS secrets, were leaked through deleted commits, posing significant security risks.

  5. Case Study: One notable incident involved a leaked GitHub PAT that granted administrative access to all repositories of Istio, an important open-source project. This could have led to severe supply-chain attacks, but the issue was quickly addressed once reported.

  6. Conclusion: The research emphasizes that once a secret is committed to a repository, it should be deemed compromised, and immediate action should be taken to revoke it, regardless of whether it has been deleted from the visible commit history.

The first alpha of Turso: The next evolution of SQLite
(The first alpha of Turso: The next evolution of SQLite)

Six months ago, a project to completely rewrite SQLite, called "Project Limbo," was announced. This project has attracted a community of over 115 contributors and is now named "Turso," which represents the next version of SQLite. Turso aims to match SQLite's reliability through modern testing techniques, including a partnership with Antithesis, an autonomous testing platform. They are so confident in their testing that they will pay $1,000 for any missed data corruption bugs.

The need for a rewrite arises from limitations in SQLite, such as issues with concurrent writes, real-time data handling, and support for non-relational data. These challenges have become more apparent with the rise of AI applications.

Turso introduces key features like an asynchronous interface for better performance, especially in web environments, and native vector search capabilities for AI and machine learning. The alpha version supports basic SQLite operations and aims to provide a reliable foundation for future development. Early adopters, such as Spice.ai, are already seeing performance benefits from using Turso.

The team emphasizes the importance of community contributions and invites those interested to join their Discord. They also acknowledge their partners, including Antithesis and Blacksmith, for their support in achieving stability and reliability in this alpha release. Overall, Turso is positioned as a modern evolution of SQLite, designed to meet the demands of contemporary applications.

Huawei releases an open weight model trained on Huawei Ascend GPUs
(Huawei releases an open weight model trained on Huawei Ascend GPUs)

The Mixture of Experts (MoE) approach in Large Language Models allows for a larger model with better learning capabilities while keeping execution costs low, as only a few parameters are activated for each input. However, some experts are used much more frequently than others, causing inefficiencies when running on multiple devices. To address this, we developed the Mixture of Grouped Experts (MoGE), which groups experts to ensure a more balanced workload. This design helps distribute the computational load evenly when executed on different devices, improving performance during model inference.

We created the Pangu Pro MoE model, which has 72 billion parameters, with 16 billion activated for each token. This model is optimized for specific Ascend NPUs and has shown improved expert load balancing and efficient execution in both training and inference. Our tests reveal that Pangu Pro MoE achieves an inference speed of 1148 tokens per second per card, with potential improvements to 1528 tokens per second using acceleration techniques. This performance surpasses other models with 32 billion and 72 billion parameters. Overall, Pangu Pro MoE provides an excellent cost-to-performance ratio and demonstrates effective parallel training capabilities, making it competitive against other leading models.

Fakespot, a tool for detecting fake online reviews, officially shut down on July 1, 2025, after nine years of operation. Founded in 2016 by Saoud Khalifah, Fakespot was created to help shoppers identify unreliable reviews, particularly on Amazon, where studies showed 43% of top-selling products had misleading feedback.

Despite its success and a $7 million funding round, Fakespot was acquired by Mozilla in 2023, which later decided to discontinue it due to sustainability challenges. Mozilla integrated Fakespot's technology into its Firefox browser but ultimately chose to refocus on core features and AI innovations, leading to the closure.

Many users expressed disappointment over the loss of the service, highlighting the ongoing need for reliable review analysis. In response to this gap, a new tool called TrueStar is being developed to provide similar services with a focus on sustainability.

In summary, Fakespot's closure marks the end of a significant resource for online shoppers, but there are emerging alternatives being developed.

A new study from the National Cancer Institute (NCI) found that air pollution is linked to genetic mutations in lung cancer tumors of non-smokers. This research analyzed lung tumors from 871 non-smokers across four continents and discovered that those living in highly polluted areas had more genetic mutations compared to those in cleaner environments. The study is part of a larger project on lung cancer in non-smokers led by Maria Teresa Landi.

Lung cancer is the leading cause of cancer deaths in the U.S., with a significant percentage of cases occurring in non-smokers. The study highlights air pollution as a major public health concern, especially as climate change worsens conditions like wildfires and extreme heat. It found that air pollution causes more mutations than exposure to secondhand smoke.

The research also noted geographic differences in mutations linked to specific pollutants, such as aristolochic acid in Taiwan, which is associated with traditional medicine. The study emphasizes the need for more research into the health effects of air pollution, especially as funding for such studies is being cut.

Experts warn that ongoing fossil fuel use not only leads to increased air pollution but also raises healthcare costs and health risks for millions of Americans. The findings call attention to the urgent need to address air quality and its impact on health.

Mathematical software has often been developed in "packages" that rely on C++ and use header files for their interfaces. This system can be cumbersome and slow. To improve this, C++20 introduced a "module" system that allows packages to export their code in a more efficient way. This summary explores how to convert large C++ mathematical software packages to this new module system, using a finite element library with 800,000 lines of code as an example. The author presents a method to create both header-based and module-based interfaces from the same code. While converting to modules requires some effort, it can reduce compile time for the library itself, even though the effects on downstream projects are unclear. The author concludes with ideas for gradually converting the entire mathematical software ecosystem to this new system over the coming years.

Summary:

This analysis explores the ratings of nootropics—substances claimed to enhance cognitive abilities—gathered from a recommendation system. The author defines nootropics broadly, including medications, plants, and even activities like sleep and exercise, which can significantly impact cognitive performance.

Key Insights:

  1. Recommendation System: The author developed a system where users rate nootropics they've tried. This system collected data from nearly 2,000 participants, resulting in over 36,000 ratings.

  2. Rating Scale: Ratings range from 0 (useless) to 10 (life-changing), based on participants' experiences. The analysis considers biases such as self-reporting and the placebo effect.

  3. Lifestyle Interventions: Sleep and exercise (especially weightlifting) received very high ratings, often outperforming well-known nootropics like Adderall and Modafinil. This suggests lifestyle changes are critical for cognitive enhancement.

  4. Peptides: Nootropics like Semax and Cerebrolysin, although underutilized, showed promising ratings and low risk profiles, but are not widely known outside Russia.

  5. Common Nootropics: Many popular nootropics (e.g., Piracetam, Ashwagandha) received mediocre ratings compared to lifestyle interventions and certain lesser-known substances.

  6. Tianeptine: This antidepressant was rated higher than other medications, raising questions about its effectiveness and perception.

  7. Zembrin: Contrary to previous surveys suggesting it was highly effective, this analysis found Zembrin's ratings comparable to normal Kanna, indicating it may not be as special as once thought.

  8. Cautions: The analysis emphasizes the importance of understanding risks associated with nootropics, especially less-studied substances, and reminds readers to approach self-reported data cautiously.

In conclusion, the results highlight the significant impact of lifestyle choices on cognitive performance and suggest that many well-known nootropics may not be as effective as commonly believed.

Sparsity Is Cool
(Sparsity Is Cool)

Summary of BackSparsity is Cool

Sparse attention models, like Native Sparse Attention (NSA), are becoming efficient alternatives to traditional attention mechanisms in large language models (LLMs). These models are faster and can handle longer contexts without significant performance loss. The study explores the attention patterns in these sparse models, providing insights into their architecture and performance.

Key Points:

  1. Challenges with Traditional Attention: Traditional attention mechanisms scale poorly with longer sequences because they require computations that grow quadratically with sequence length. Most queries only need to focus on a small subset of tokens, making full attention inefficient.

  2. Sparse Attention Approaches:

    • Native Sparse Attention (NSA) and Mixture of Block Attention (MoBA) are two recent models designed to incorporate sparsity directly into the training process, improving both efficiency and performance.
    • NSA uses a multi-branch design, allowing each query to attend to compressed, selected, and local contexts simultaneously, improving both speed and expressivity.
  3. Implementation and Efficiency:

    • The NSA model is implemented with hardware in mind to optimize memory access and computational efficiency. It manages attention computations dynamically to reduce unnecessary operations.
    • The model demonstrates significant speedups over traditional attention mechanisms during both training and inference.
  4. Attention Patterns:

    • The study provides the first detailed analysis of attention maps in sparse models, revealing different patterns compared to dense attention.
    • Attention sinks are identified, where certain tokens receive disproportionately high attention scores, often used to reduce computation for less relevant tokens.
  5. Performance Evaluation:

    • NSA outperforms dense attention models on several benchmarks, especially in long-context tasks.
    • The model's design allows it to generalize better over longer contexts, maintaining performance even as sequence lengths increase.
  6. Future Directions: The findings encourage further exploration of the mechanisms behind sparse attention and suggest potential improvements in model architecture for better efficiency and performance.

In summary, sparse attention models like NSA present a promising evolution in the design of LLMs, effectively balancing computational efficiency with the ability to process long contexts.

Azure API vulnerability and roles misconfiguration compromise corporate networks
(Azure API vulnerability and roles misconfiguration compromise corporate networks)

Summary

Security researchers have found serious vulnerabilities in Azure's built-in roles and API configurations that could jeopardize enterprise networks.

  1. Over-Privileged Roles: Some Azure roles grant more permissions than intended. For example, roles like the Managed Applications Reader allow users to read all Azure resources instead of just specific ones. This can lead to unauthorized access to sensitive information.

  2. API Vulnerability: A flaw in the Azure API allows attackers with read-only permissions to leak VPN pre-shared keys. These keys are crucial for connecting to internal networks, enabling attackers to access cloud resources.

  3. Attack Chain: By exploiting these vulnerabilities, a weak user can gain access to both cloud and on-premises resources. Attackers can steal credentials, discover sensitive data, and plan further attacks.

  4. Mitigation Strategies:

    • Audit Roles: Organizations should review and avoid using the over-privileged roles.
    • Limit Scope: Assign roles with restricted access to only necessary resources.
    • Create Custom Roles: Instead of using built-in roles, custom roles with specific permissions should be created.
  5. Vendor Response: Microsoft acknowledged the VPN vulnerability as significant and fixed it, but deemed the over-privileged roles issue to be of low severity, only updating the documentation instead of rectifying the roles.

  6. Key Takeaway: Organizations must be vigilant and proactive in managing permissions and roles in Azure, as relying solely on cloud providers can lead to security oversights.

For further security enhancements, organizations can seek specialized help or services to bolster their Azure environments.
