The company is unapologetic about its approach and encourages users to embrace this shift away from human involvement, suggesting that it alleviates the burdens of daily life. They also acknowledge the ethical concerns regarding their AI's development, including the use of creative works from artists without compensation.

In essence, Replacement.AI is pushing for a future where AI fully replaces human roles, prioritizing efficiency and profit over human connection and welfare.

A recent study from Texas A&M University reveals that abandoned land in Houston contributes to dangerously high temperatures in certain neighborhoods, particularly affecting low-income residents. Research led by Dr. Dingding Ren found that vacant lots with vegetation can help cool nearby areas, while abandoned buildings and paved lots can increase temperatures by up to 20 degrees Fahrenheit.

Using drone images and satellite data, the study mapped heat levels across various sites in Houston, identifying hotspots that correlate with social vulnerability. Areas with more trees and open land tend to be cooler, while those with concrete absorb heat and retain it, raising nighttime temperatures.

Dr. Ren highlighted that the extreme heat makes public spaces unsafe for walking or biking, especially for low-income individuals who often lack shade. He suggests that increasing green spaces and using vacant lots for gardens could help mitigate heat risks and improve public health. The study aims to guide urban planners in prioritizing cooling strategies for Houston's most vulnerable neighborhoods.

The text discusses a concept called "spherical cow" modeling in programming, which refers to simplifying complex problems by ignoring certain variables to focus on key aspects. This technique helps in understanding problems better, but it risks oversimplifying and can lead to complications if relied upon too heavily.

The author highlights that functional programming (FP) is one such "spherical cow," but it neglects important design elements like memory conservation. Using only one model can create issues, such as complicated workarounds in coding. The author advocates for embracing multiple approaches to problem-solving rather than sticking to one.

Additionally, the text critiques how programming languages and notations have evolved, suggesting that a more diverse set of tools and views should be used to address different challenges in programming. It emphasizes the value of asynchronous programming and the need for better notational systems to express complex operations more clearly.

Summary: How to Build a 12V DC Electric Heating Element

This guide explains how to create a 12V DC electric heating element from scratch for solar-powered cooking devices.

Key Points:

1. Purpose: The heating element is designed to connect directly to a solar panel, eliminating the need for batteries or additional electronics, and is used in various solar cooking appliances.

• A simple API with one function, "diversify," that supports several strategies (MMR, MSD, DPP, and COVER).
• It’s lightweight, with only NumPy as a dependency, making it easy to install.
• It’s fast, providing quick results in milliseconds.

The author mentions that while complex methods like cross-encoders are popular, simpler methods can often yield better results. This helps systems present more varied and informative results.

For more information, check out the code and documentation on GitHub. The author is open to feedback and suggestions for new strategies.

This week, the focus has been on fine-tuning AI models, particularly with the launch of Tinker by Thinking Machines Labs, a startup valued at $12 billion. Founded by former OpenAI CTO Mira Murati, Tinker aims to revitalize fine-tuning as a platform for research collaboration.

Fine-tuning had been popular after the rise of large language models (LLMs) but quickly fell out of favor, now making up less than 10% of AI workloads. Early NLP relied on specialized models, but the introduction of the Transformer architecture in 2017 changed that, allowing for model pre-training and fine-tuning.

However, as LLMs grew in size, traditional fine-tuning became costly and complex. The introduction of LoRA (Low-Rank Adaptation) in 2021 made fine-tuning more efficient by adding small matrices instead of retraining every parameter. Yet, despite its advantages, teams found they could achieve similar results with prompt engineering and retrieval-augmented generation without retraining.

Recently, fine-tuning is gaining attention again due to improvements in GPU-as-a-service platforms, evolutionary model changes, and a demand for models that understand specific requirements. Tinker represents this shift, offering a modern fine-tuning approach that balances ease of use with detailed control for researchers.

The fine-tuning process has also evolved into a modular system, allowing multiple adapters for different needs. However, challenges remain, particularly in model evaluation, which is often inconsistent and expensive. New approaches, including online reinforcement learning, may help address these issues and lead to continuous learning.

Overall, fine-tuning is becoming a strategic tool for organizations, focusing on ownership and specialized model performance rather than just a technical process.

Summary of Improving PixelMelt's Kindle Web Deobfuscator

PixelMelt recently shared a method for downloading purchased Kindle books without DRM, but it faced several issues. The original process involved mimicking a web browser and downloading JSON files to reconstruct text from obfuscated SVGs using OCR (Optical Character Recognition).

Key problems included:

1. The tool only worked with the US Amazon site, which was easy to fix.
2. The OCR produced many errors, such as confusing punctuation marks and incorrect line breaks, making the text hard to read.

To improve the process, a new approach was developed:

• Instead of processing single characters, the entire page was OCR'd for better results.
• Characters were extracted from SVG paths, resized, and placed on a blank page based on their specified dimensions.
• Tesseract 5, an OCR engine, was used to convert the images to text, with options for HTML and PDF outputs.

Despite improvements, some mistakes remained:

• Superscript footnotes were often missing.
• Words could run together, and formatting (like bold or italics) was lost.

Images were not downloaded, and the output lacked semantic meaning and proper layout. The process is still manual and not perfect, but it provides a way to access Kindle books. The author has stopped buying from Amazon, finding alternatives like Kobo more appealing for their easier DRM management.

The text discusses the evolving landscape of social media and the impact of AI on content creation. The author observes a rise in AI-generated content on platforms like Instagram and expresses concern about the quality and authenticity of such content. They predict that many people will move away from traditional social media due to its overwhelming and often misleading content, leading to "decision fatigue."

The author emphasizes the importance of human touch in content creation, suggesting that skilled writers and programmers will be needed to ensure quality and security in a future where AI-generated content may dominate. They speculate that social networks may become more fragmented, with smaller, possibly private platforms emerging.

The text also references the IndieWeb movement's principles of POSSE (Publish on your Own Site, Syndicate Elsewhere) and PESOS (Publish Elsewhere, Syndicate to your Own Site). The author encourages individuals to make their own websites the primary source of their content, despite challenges with external links and API access. Overall, the message is that as technology evolves, maintaining control over personal content will be increasingly important.

The essay by Sophia Rosenfeld discusses how the modern concept of freedom has become closely tied to the idea of choice, particularly in consumer culture. In many parts of the world, especially in the United States, individuals frequently make choices about everyday items and significant life decisions. This abundance of choice is often celebrated as a hallmark of freedom, yet it can also lead to confusion and dissatisfaction, as people struggle to make decisions.

Historically, the rise of choice began in the 17th and 18th centuries, with the growth of consumer shopping and the idea of personal preference. Choices expanded from shopping for goods to selecting beliefs, partners, and political representatives. The 19th century saw further development in the realm of romantic and political choices, culminating in secret voting practices that aligned with the growing emphasis on individual choice.

The 20th century brought even more opportunities for choice to various groups, including women and marginalized communities. However, the essay warns that while choice can empower individuals, it can also lead to an emphasis on individualism that neglects collective needs and responsibilities. Critics point out that the focus on choice can create a false sense of freedom, especially when options are limited or when choice becomes overwhelming.

Rosenfeld argues that it's essential to critically examine our relationship with choice and consider alternative visions of freedom that prioritize community and collective well-being. The historical context of choice provides a framework for understanding its implications on personal and societal levels, suggesting that freedom may not always be found in having many options.

What Are RFCs? A Simple Overview

RFCs, or Requests for Comments, are essential documents that outline how the internet works and how different systems communicate. They provide the standards and protocols necessary for computers to share information effectively, much like how human languages have agreed rules for communication.

Key Points:

1. Importance of Communication Standards: Just as people need a common language to talk, computers require shared rules to communicate over the internet. RFCs serve as these blueprints.

2. The Birth of the Internet: The internet evolved over decades, starting from the 1950s when the U.S. government initiated ARPA to develop a reliable communication system. The first successful network was ARPANET, which used packet-switching technology to send data in small units.

3. Creation of RFCs: The first RFC was published in 1969 to share ideas on network operations. Each RFC is numbered permanently, creating a historical record of internet development.

4. Role of RFCs Today: RFCs are maintained by the Internet Engineering Task Force (IETF) and define core technologies like TCP/IP and HTTP. They are crucial for anyone developing software or systems that need to communicate over the internet.

5. How to Read RFCs: Understanding RFCs is vital for building reliable systems. They use specific terms (like "MUST" and "SHOULD") to clarify requirements, so it's important to read them thoroughly to avoid misinterpretation.

In summary, RFCs are foundational to the internet, guiding how systems work together and ensuring consistent communication. They are valuable resources for anyone interested in technology.

The author compared the power consumption of their old refrigerator, a 30-year-old UPO Jääkarhu, with a new, mid-range model. The old fridge was noisy, had constant ice buildup, and consumed significantly more electricity, using 2.6 kWh daily compared to the new fridge's 0.7 kWh. This meant the old fridge consumed about 3.7 times more power.

After replacing the old fridge, the monthly electricity consumption dropped from around 78 kWh to roughly 21 kWh. This change, along with a new dishwasher, resulted in a 10-20% reduction in overall power use in the apartment. The author estimates it will take about 38 months for the new fridge to pay for itself through energy savings, assuming an average electricity rate of 17 cents per kWh.

The author expressed concern about the durability of the new refrigerator compared to the old one, which lasted 30 years. They gave away the old fridge to someone in need and noted they appreciated some of the quirks of the old model, like how it kept ice cream colder.

OpenAI recently faced backlash after claiming that its GPT-5 model had solved 10 previously unsolved math problems, specifically Erdős problems. This announcement, made by OpenAI manager Kevin Weil on social media, was quickly criticized by mathematicians, including DeepMind CEO Demis Hassabis, who described the situation as embarrassing. It turned out that GPT-5 had not genuinely solved these problems but had instead found existing research that the operator of erdosproblems.com was not aware of.

Critics pointed out that the language used in the announcements was misleading and emphasized the need for careful communication in the field, especially given the high stakes involved in AI research. Despite the initial hype, mathematician Terence Tao noted that AI, including GPT-5, is currently more beneficial as a tool for speeding up research tasks like literature reviews, rather than solving complex mathematical problems independently.

Recovery teams have found an undamaged $62 SanDisk microSD card from the Titan submersible wreckage, containing 12 still images and nine videos. The camera, made to withstand depths of 6,000 meters, suffered some damage, but the memory card remained intact. Investigators created a copy of the card to preserve its contents and discovered the images and videos were taken at a staging area in Newfoundland, not at the Titanic wreck site. Unfortunately, there were no recordings from the dive that led to the submersible's tragic implosion.

The text discusses why the sort command produces different results on macOS compared to Linux when sorting strings, even with the same locale settings.

Key points include:

1. Different Sort Orders: When sorting the package names "python-dev" and "python3-dev", macOS lists them as:

   • python-dev
   • python3-dev While Linux (Ubuntu 20.04) sorts them as:
   • python3-dev
   • python-dev

2. Locale Issues: The difference in sorting is due to the underlying collation rules defined by the LC_COLLATE locale setting. On macOS, the LC_COLLATE for many locales, including en_US.UTF-8, points to a basic ASCII-based collation that does not account for more nuanced sorting.

3. macOS Collation Source: The collation rules on macOS are derived from an old FreeBSD version and are simplistic, treating characters based on their byte values without following standard rules. This results in a less sophisticated sorting mechanism.

4. Linux Collation Source: In contrast, Linux systems use the GNU C Library (glibc) for locale functions, which implements more complex sorting rules based on the ISO 14651 standard. This leads to more accurate sorting results.

In summary, the differing behavior of the sort command on macOS and Linux is mainly due to the simplicity of the collation rules used by macOS compared to the more sophisticated rules employed by Linux.

A significant discovery has been made in an Oxfordshire quarry, where a dinosaur trackway from 166 million years ago is being unearthed. This summer, paleontologists uncovered one of the longest dinosaur trackways in the world, measuring 220 meters. The footprints likely belong to a large, long-necked herbivore known as Cetiosaurus.

The site has a history of dinosaur finds, with previous discoveries in the 1990s and last year. This year, a controlled explosion was used to remove limestone, allowing researchers to carefully excavate the footprints. In addition to the giant tracks, smaller prints from a two-legged carnivore, Megalosaurus, were also found.

These footprints provide valuable insights into dinosaur behavior, showing how they moved and interacted. For example, one print is misaligned, suggesting the dinosaur paused for a moment. The preservation of these tracks is rare and requires specific conditions to occur.

Researchers also found tiny marine fossils at the site, indicating that the area was once a tropical lagoon. The discovery of these dinosaur footprints is exciting for scientists and highlights the prehistoric history of the UK. More trackways may still be uncovered as excavation continues.

Summary of "The Accountability Problem" Keynote

Overview

In this keynote, the speaker discusses the "Accountability Problem" in software development, particularly in entrepreneurial companies. He emphasizes the need for software departments to define their own accountability rather than allowing business partners to dictate it based on misconceptions about software development.

Key Points

1. Understanding Context: The speaker, a VP of Engineering at OpenSesame, shares his experiences working with late-stage startups and the importance of context when applying advice.

2. Biases Affecting Interpretation: He highlights how biases shape our understanding of software development. For instance, misconceptions from non-developers lead to the belief that software development is merely about writing code, when it is actually about collaboration, communication, and iterative discovery.

3. The Accountability Challenge: Many organizations view software development through a project-based lens, expecting clear timelines and deliverables. This results in a lack of proper accountability and often leads to poor software quality.

4. Defining Accountability: The speaker argues that accountability should focus on the results software teams create, rather than specific features or deadlines. He proposes the concept of "Product Bets," which are strategic investments aimed at achieving business outcomes.

5. Product Bets Explained:

   • Definition: A Product Bet outlines a business outcome and the means to achieve it, emphasizing estimated value rather than exact deliverables.
   • Components: Each bet includes a headline for the outcome, a sponsor from leadership, and an estimated present value derived from potential sales, upsells, retention improvements, and costs.

6. Implementing Product Bets: The speaker shares his experience introducing Product Bets at OpenSesame, which involved leadership buy-in and the development of a financial model to estimate the potential value of each bet.

7. Challenges and Progress: He acknowledges the initial resistance and challenges in getting leadership to engage with the Product Bet framework but notes that over time it has led to a more focused conversation about value rather than just features and deadlines.

8. Final Thoughts: The speaker concludes that software development teams can take accountability for the outcomes they generate. By adopting Product Bets, they can demonstrate their value to the organization and align better with the expectations of other business departments.

Conclusion

The keynote emphasizes the importance of redefining accountability in software development to focus on results and value creation, rather than merely on timelines and features. By adopting the concept of Product Bets, software teams can better communicate their contributions to the business and enhance collaboration with other departments.

Reports indicate that No-IP's dynamic DNS service has been disrupted in Spain due to actions by local ISPs, which blocked the service after receiving a court order. Users reported seeing 'Error 451' when trying to access the service, which is critical for those whose IP addresses change frequently, like for remote access to CCTV cameras.

The ongoing legal dispute in the U.S. Supreme Court between record labels and Cox Communications highlights the debate over how to handle online piracy. The record labels advocate for cutting internet access to entire households of those caught pirating, while Cox argues this is too harsh. This raises questions about the fairness of collective punishment, as innocent family members might lose access to essential services due to one person's actions.

In Spain, ISPs are blocking access to numerous IP addresses linked to potential piracy, affecting many users without prior notice or clear explanations. This lack of transparency has frustrated customers, who often receive vague responses about the reasons for the blocks. Despite these issues, the blocking measures do not currently appear to extend to IP addresses, limiting the overall impact.

This situation in Spain is unprecedented in Europe, where similar blocking measures are becoming more common, but not to this extent of collateral damage. The lack of accountability and communication from ISPs raises concerns about the fairness of these actions in a regulated environment.

On September 30, 2025, Raymond Chen discusses the term "convicted" in his writing. He likely explores its meaning and implications, focusing on how it relates to legal contexts or personal experiences. The text aims to provide insights into the concept of being found guilty of a crime.

Summary: Why the Open Social Web Matters Now

Ben Werdmuller, speaking at FediForum, emphasizes the importance of the open social web in today's world, marked by rising authoritarianism and threats to vulnerable communities. He reflects on his experience in building open-source social networking platforms and highlights three key questions for developers:

1. Who are we helping? - Understand the specific communities and their needs.
2. Why are we the right team? - Ensure your team has the relevant experience and understanding of the communities served.
3. How can we serve their needs better? - Focus on providing practical solutions that address real issues facing these communities.

Werdmuller discusses the decline of traditional journalism and the growing control of social media by a few powerful companies, which can lead to misinformation and corruption. He advocates for decentralized networks that empower communities to communicate and organize safely, especially in light of increasing surveillance and authoritarian measures.

He argues that the open social web can provide a refuge for marginalized groups, enabling secure communication and collective action. The future of social networking should prioritize community needs and foster collaboration without centralization. Ultimately, Werdmuller encourages developers to build platforms that genuinely meet the needs of communities, particularly those facing real dangers, and to engage with these communities from the outset.

Turbo Stream elements are special HTML elements that can change a webpage's content dynamically when added. By using a <turbo-stream> tag with an action attribute, you can perform actions like adding, replacing, or removing content. For example, when a user submits a form to create a new book, the server can respond with a Turbo Stream element to add that book to the list on the page.

Here's how Turbo works in two main parts:

1. Handling Form Submissions:

   • Turbo listens for form submissions in the browser. When a form is submitted, it prevents the default submission, then sends the form data to the server using the fetch API.
   • It adds a special header (Accept: text/vnd.turbo-stream.html) to tell the server to respond with Turbo Stream elements. If the server does not respond correctly, Turbo will raise an error.

2. Processing Turbo Stream Responses:

   • Turbo listens for responses from the server. If the response is a Turbo Stream, it adds the content to the DOM and executes any actions defined in the Turbo Stream elements (like appending or removing content).
   • Multiple Turbo Stream elements can be sent in one response, and all actions will be performed in order.

If you're using regular fetch requests, you can manually set the Accept header to receive Turbo Stream responses.

In summary, Turbo Stream simplifies dynamic updates to a webpage by intercepting form submissions and handling server responses effectively.

Meridah Nandudu, a 35-year-old from Uganda, transformed her life and her village's coffee industry by empowering women farmers. After struggling to find a job in social work, she decided to start her own coffee business, Bayaaya Specialty Coffee, which now sources beans from over 600 women farmers.

Growing up in a male-dominated coffee culture, Nandudu witnessed the challenges women faced, including domestic violence and financial dependence on their husbands. Motivated to create change, she returned to her village after a difficult marriage and began training in coffee farming through a free program.

Nandudu faced initial resistance from men who controlled the coffee sales, but she incentivized them to allow their wives to sell directly to her. Gradually, many men accepted this arrangement, leading to increased financial independence for women.

Today, Nandudu's success has inspired many in her community, and she plans to expand her business by roasting and exporting coffee, aiming to empower even more women. Her mission is to help women gain control over their lives and finances, moving from dependence to empowerment.

Summary:

Ruth Selman shares exciting news about a 17th-century letter written in code by William Perwich, which has been successfully deciphered after 350 years. The letter, sent from the court of Louis XIV in France on April 9, 1670, was decoded by two groups of cryptographers: Matthew Brown and a team of Dr. George Lasry, Professor Norbert Biermann, and Tomokiyo Satoshi.

The decoding process involved determining a 20-column structure and identifying 'null' letters that needed to be discarded. They used a combination of codebreaking software and manual effort to interpret the letter, which discusses soldiers' grievances about the king's favoritism toward his mistresses and hints at political alliances.

Although the letter contains some numerical codes that remain unsolved, its findings reveal the political tensions of the time, specifically regarding Louis XIV's relationship with the Dutch and his strategies for war. Overall, the letter provides intriguing insights into the court's gossip and politics from that era.

The Blog System/5A newsletter explores various topics like operating systems, programming languages, and software engineering. The author reflects on programming tools from the late 1980s and early 1990s, particularly text-based Integrated Development Environments (IDEs) like Turbo C++ and QuickBASIC, which were powerful and user-friendly.

In contrast, modern tools like Vim and Emacs, while powerful, often lack the intuitive design and ease of use found in those older IDEs. The article discusses the evolution of text-based user interfaces (TUIs) and how they are making a comeback due to advancements like Language Server Protocol (LSP).

While graphical IDEs like VSCode are popular today, TUIs have advantages for remote work, lower resource consumption, and open-source flexibility. The author criticizes modern IDEs for being bloated compared to older tools, suggesting that despite technological advancements, the fundamental experience of coding hasn’t changed significantly in 30 years. The piece concludes with a call to appreciate the simplicity and effectiveness of past programming environments.

The paper discusses a new type of garbage collector called "immix," designed to improve memory management in managed programming languages. As applications increasingly use short-lived objects, efficient garbage collection becomes crucial for performance. Traditional garbage collectors—such as semi-space, mark-sweep, and mark-compact—each excel in some areas but have trade-offs that leave them lacking in others.

Immix belongs to a new family of collectors known as "mark-region," which combines two strategies: marking and opportunistic defragmentation. This allows immix to efficiently reclaim memory while also ensuring that objects are allocated contiguously, enhancing performance.

Key points about immix include:

• It uses large contiguous memory regions for better performance, while also managing smaller regions to maintain efficiency.
• It improves overall application performance by 7% to 25% compared to traditional collectors, with some benchmarks showing performance improvements of up to 75%.
• The collector operates with minimal memory overhead, requiring only 3% more memory than the mark-compact collector but 15% less than mark-sweep.
• Immix is designed to work well in both full heap scenarios and as part of generational collectors, showing superior performance across various benchmarks.

Overall, the introduction of immix presents a promising advancement in garbage collection, balancing speed, space efficiency, and performance effectively.

Using PEGs in Janet: A Simple Guide

Janet is a small programming language that uses parser expression grammars (PEGs) instead of regular expressions for parsing. PEGs allow you to define rules that can refer to each other, making them very flexible.

Steps to Create a PEG for HTML Parsing

1. Define the Main Rule: Start with a main rule that indicates how parsing begins. The main rule matches a sequence of tagged elements until the end of the string.

2. Define Tagged Rule: Create a rule for tagged elements, which includes an opening tag, a value, and a closing tag.

3. Define Open-Tag Rule: This rule matches the opening tag and captures the tag name for later use.

4. Define Close-Tag Rule: This rule matches the closing tag. It checks if the tag names match using a function.

5. Define Value Rule: The value can be a combination of tagged and untagged content.

6. Define Untagged Rule: This rule matches any characters that are not part of a tag.

7. Drop Back Reference: To handle nested tags, use a function that removes the tag name from memory once used.

8. Capture Tag Names and Values: Modify the rules to return structured data, capturing tag names and their values.

Compiling the Grammar

If you want to use the grammar multiple times, you can compile it for better performance.

Example Usage

You can test your grammar by matching it against HTML strings. For instance, the grammar can successfully parse a string like <p><em>Hello</em> <strong>world</strong>!</p> and return structured data. If the input is invalid, like a mismatched closing tag, it will return nil.

Conclusion

PEGs in Janet provide a powerful way to parse data beyond what regular expressions can offer, making them a valuable feature of the language.

The article by Abhishaike Mahajan discusses the recent surge in funding for protein foundation model startups, raising questions about the rationale behind these investments. Notable companies received significant funding, such as Isomorphic Labs ($600M) and Xaira Therapeutics ($1B). Critics argue that these investments may not be justified, as many models appear similar in performance, especially with the rise of open-source alternatives.

However, Mahajan presents an optimistic view, suggesting several reasons why investors might see value in these startups. One key argument is the potential for "multiproperty optimization," where private models could manage multiple biochemical properties simultaneously, leading to breakthroughs beyond simple binding tasks. This could automate significant parts of the preclinical workflow, potentially reducing costs and improving efficiency in drug development.

Mahajan emphasizes that while current benchmarks focus heavily on binding, other properties like stability and manufacturability are crucial too. The true potential of these models may lie in their ability to integrate various objectives, which could lead to innovative advancements in biology and drug discovery.

The author, a fan of Rust, expresses frustration with the language's tendency towards excessive abstraction in its ecosystem. They argue that many Rust libraries, while powerful, are overly complex and can make simple tasks feel daunting. This results in a culture where writing convoluted code is seen as the norm, often leading developers to create overly generic solutions that cater to hypothetical future needs rather than immediate requirements.

The author contrasts two types of Rust developers: those who enjoy the art of abstraction and those who just want functional, uncomplicated code. They believe that while abstraction has its place, it should be used judiciously. Code should remain understandable and maintainable, and developers should prioritize clarity over cleverness.

The takeaway is to strive for simplicity in coding, ensuring that new abstractions genuinely serve current needs rather than future possibilities. The author hopes to inspire others to write straightforward code, avoiding unnecessary complexity.

Summary of "Caveat promptor" by Lorin Hochstein

After a major incident, leaders often urge engineering teams to be more careful to prevent future problems. However, this approach doesn't improve reliability because it overlooks a key concept in resilience engineering: the efficiency-thoroughness trade-off (ETTO).

The ETTO principle, introduced by Erik Hollnagel, explains that there's a balance between completing tasks quickly and being thorough. In software development, using AI tools to generate code can speed up the process, but this also requires careful human review to catch any mistakes the AI might make.

As engineers become familiar with AI-generated code, they learn where to focus their review efforts, aiming to minimize time spent while maintaining quality. However, mistakes can still slip through, leading to incidents. Reminders to be careful after such incidents don't address the underlying issue: the efficiency-thoroughness trade-off remains a constant challenge, regardless of how AI changes the development process.

A study by researchers from Penn State and Oregon State University found that most people struggle to recognize bias in AI systems, particularly when it comes to how these systems interpret emotions based on race. The researchers used training data that primarily featured white faces for happy emotions and Black faces for sad emotions. Most participants in the study did not notice the bias unless they belonged to the negatively portrayed group.

The researchers created different versions of an AI system to detect facial expressions and tested it with 769 participants of various racial backgrounds. They found that people generally trust AI to be neutral, even when it is biased. Black participants were more likely to identify bias, especially in scenarios where their group was misclassified.

The study highlights the importance of understanding how AI learns from unrepresentative training data and its implications for fairness across all racial groups. The researchers plan to focus on improving public awareness and understanding of algorithmic bias in future studies.

Summary of StageConnect

StageConnect is an Arduino library designed to create devices that connect using Analog Devices AD242x chips, like the AD2428. It leverages the automotive A²B technology to link devices such as the Behringer WING and Midas DP48, transmitting 32 channels of high-quality audio through simple XLR connectors.

Usage

To use StageConnect, include the main library and the I2C wrapper class. Set up the I2C connection and create instances of the classes. You will need to call stageConnect.update() every 100 milliseconds. For guidance, check the example sketch for using callbacks and receiving channel names.

Technical Details

• Recommended cable length is up to 15 meters, but Behringer supports longer cables.
• Be cautious when adjusting hardware parameters due to the complexity of the AD242x chip filter network.
• Refer to the AD2428MINI schematics for electrical connections.
• Use unique brand IDs above 0x80 to avoid conflicts with other products.

A United flight from Denver to Los Angeles had to divert to Salt Lake City on October 16, 2025, due to a crack in its cockpit windshield. There are theories that the crack may have been caused by space debris, as suggested by a photo showing scorch marks on the windshield. However, experts believe the crack is likely due to a fault in the windshield heating system, which can cause overheating and is a known issue in modern aircraft.

The plane was at 36,000 feet, making bird or hail strikes unlikely. Cracked windshields are common in aviation, and such diversions happen regularly. An FAA report from 2023 indicated that the risk of space debris causing harm to aviation is very low, with no confirmed cases of aircraft being struck by space debris. As of now, the aircraft remains grounded in Salt Lake City more than a day after the incident.

The text discusses the concept of treating control flow structures like "if" and "for" as regular functions instead of special syntax, as seen in languages like Python. Here are the key points:

1. Special Syntax vs. Functions: In Python, control structures like "if" and "for" have fixed syntax and cannot be manipulated like functions. In contrast, languages like REBOL, Red, and Rye treat these structures as functions, allowing for greater flexibility.

2. Advantages of Functions:

   • Consistency: All language features follow the same structure, making it easier to learn and use.
   • Flexibility: Functions can be composed, passed around, and combined, enhancing the ability to create complex behavior.
   • Extensibility: Developers can create custom control structures without limitations.

3. Examples: The text provides examples comparing Python and Rye. In Rye, constructs like conditionals and loops are function calls, which can accept blocks of code as arguments, allowing for more dynamic programming.

4. Piping and Applying Functions: In Rye, you can pipe conditions into functions and apply functions to arguments easily, which is not possible in Python due to its syntax restrictions.

5. Creating Custom Control Structures: Since control flow is treated as functions, users can define their own structures, like "unless" and "until," expanding the language's capabilities.

6. Performance and Tooling: While Python can optimize special syntax at compile time, languages like Rye may have runtime overhead. However, having everything as functions simplifies tooling and documentation.

Overall, the text advocates for the benefits of viewing control flow as functions, highlighting the improvements in consistency, flexibility, and extensibility in programming languages that adopt this approach.
