Bryan Bedford, nominated by President Trump to lead the Federal Aviation Administration (FAA), has falsely claimed for years in his biography that he holds a "commercial" pilot license, which he does not possess. His biography at Republic Airways, where he is CEO, stated he held commercial, multi-engine, and instrument ratings, but this was corrected after inquiries from POLITICO. FAA records confirm that Bedford is a licensed private pilot but lacks commercial credentials.

Although Bedford has passed some exams required for commercial certification, he has never claimed to be a commercial airline pilot. The Department of Transportation (DOT) stated that Bedford's mention of commercial qualifications was an administrative error. Despite this controversy, there are no significant concerns about Bedford's nomination for the FAA position, especially as the agency seeks stability after recent leadership issues.

During his confirmation hearing, Bedford was praised by Republican senators, while Democrats focused on other safety-related topics without raising the issue of his pilot credentials. The claim about his commercial rating has been removed from various sections of Republic Airways' website following scrutiny.

The memoir, "The Talented Ms. Highsmith," recounts the author's experiences working for the famous author Patricia Highsmith during her final months. At twenty, the author moved into Highsmith's home in Switzerland, surrounded by her books and feeling a sense of unease because of Highsmith's dark themes of murder in her writing.

The journey to this position began with a dinner invitation from friends, where the author learned about Highsmith needing assistance. Despite having read only one of her novels, the author volunteered for the job and soon found herself in Highsmith's world, where she navigated the author's eccentricities, health issues, and strict routines.

Highsmith was described as reclusive and difficult, often isolating herself and expecting the author to cater to her needs without much communication. The author struggled with feelings of responsibility and isolation while working for someone who was both a literary genius and deeply troubled.

Throughout their time together, the author read Highsmith’s works and learned about her life, grappling with the complexity of Highsmith's personality and her longing for love and acceptance. After a brief but impactful period, the author left to return to her studies, and Highsmith's health declined shortly thereafter.

Reflecting on their time together, the author concludes that Highsmith, despite her harsh demeanor, craved love and connection. The memoir highlights the struggles of a unique relationship and the lasting impact of Highsmith’s legacy, even after her death. The author later revisited Highsmith's house, noting its transformation into something unrecognizable, symbolizing the changes that occur after a person’s passing.

Robotaxis, particularly Waymo's self-driving cars, are currently more expensive than traditional ride-hailing services like Uber and Lyft. A recent study by Obi shows that Waymo's average ride costs around $20.43, compared to Uber's $15.58 and Lyft's $14.44. Despite the higher prices, Waymo has seen a strong demand, providing 250,000 paid trips weekly across four cities.

The study revealed that Waymo's pricing is less dynamic and more variable than Uber and Lyft, largely due to its limited number of vehicles. This results in higher costs for shorter trips and longer wait times. For instance, Waymo rides can be significantly more expensive for short distances compared to its competitors.

Obi also surveyed riders and found that 70% prefer driverless cars over traditional rides, although safety remains a significant concern for many. Despite the higher costs, some customers are willing to pay a bit more for the novelty and comfort of a driverless ride, indicating a growing interest in this technology.

Web map tiles represent a significant advancement in geospatial technology, transforming how users interact with digital maps. Instead of static images, tiling allows for dynamic exploration of maps by breaking geospatial data into manageable squares at various zoom levels. This shift has greatly influenced public interest in geography and maps.

Although Google Maps is often credited with popularizing map tiles, the concept existed prior to its implementation. Notably, Roger Tomlinson’s Canada Geographic Information System (CGIS) used a tile-based structure in the 1960s. The technique, involving the Morton Matrix (or z-order curve), was developed to improve data processing efficiency.

Other related concepts include quad trees, which were introduced in computer science literature in the 1970s for storing geospatial data. Several patents, including ones from PRC Public Sector and WildTangent, also contributed to the map tiling concept, although it is unclear if these companies ever utilized their patents effectively.

In 1997, a Bell Labs researcher, Michael Potmesil, presented a paper outlining a tile-based architecture for web maps, predating Google Maps’ patent. This shows that the idea of map tiles was not exclusively created by one entity but was a culmination of ideas from various researchers over time. Thus, attributing the invention of map tiles solely to Google Maps overlooks the contributions and groundwork laid by others in the field.

   • Ousterhout identifies dependencies and obscurity as key factors contributing to complexity.
   • He notes that complexity manifests in symptoms like change amplification (where changes impact many parts of the system) and cognitive load (information developers must manage).

3. Zach Tellman's View:

   • Complexity is defined as the total of all explanations needed to understand software, particularly focusing on future explanations.
   • He emphasizes that simplicity is relative to an audience's expectations.
   • Tellman introduces concepts like coupling (how concepts are explained together) and "surprisal" (how unexpected information is).

Comparison:

• Hickey's definition is more objective, while Ousterhout's and Tellman's are subjective, reflecting personal experiences with complexity.
• Hickey believes in minimizing complexity directly, whereas Ousterhout and Tellman acknowledge the subjective nature of complexity and focus on improving understanding.

Conclusion: Tellman's definition is seen as particularly effective, as it encompasses the subjective experience of software development. The author encourages discussions about complexity to focus on future explanations to foster better communication and understanding in software design.

AI models may behave differently when they know they're being evaluated, which can make assessments less reliable. We explored whether advanced language models can tell if transcripts come from evaluations or real-world use, a skill we call "evaluation awareness." We created a diverse set of 1,000 prompts and transcripts from 61 datasets to test this. The models showed better-than-random evaluation awareness, with Gemini-2.5-Pro scoring 0.83, though humans still performed better at 0.92. Both AI and humans were more accurate in identifying evaluations in interactive settings compared to chat. Additionally, models were good at understanding what evaluations were testing. Our findings suggest that these advanced models have a significant but not yet superior level of evaluation awareness, and we recommend monitoring this ability in future AI developments.

To improve pretrained language models for specific tasks, current methods require human input to specify desired behaviors. However, it's challenging to provide high-quality supervision for these advanced models. To solve this issue, we present a new unsupervised approach called Internal Coherence Maximization (ICM), which fine-tunes models using labels they generate themselves, without relying on external supervision. Our method performs as well as traditional training methods that use high-quality labels and outperforms those that use crowdsourced human input on various tasks. Additionally, it better harnesses the superhuman abilities of these models. We also demonstrate that ICM can enhance the training of advanced language models, leading to a reward model and an assistant that surpass the performance of those trained with human supervision.

Jacob Brazeal shares his experience of improving his bullet chess game. After playing chess for a long time, he realized he was much better at blitz than bullet games. Recently, he discovered a new way to move pieces on the computer by clicking on the piece first and then the target square, instead of dragging and dropping. This change saved him about 0.25 seconds per move, leading to a significant increase in his bullet chess rating—over 200 points in one day, reaching a personal best.

He explains that the click-and-click method is faster and allows for better decision-making, reducing the need for rushed pre-moves that often result in mistakes. This improvement has narrowed the gap between his blitz and bullet ratings, and he feels he now has enough time to think through his moves. Jacob wonders if others have been using this technique all along.

Summary of Investigation into Amsterdam's Fraud Detection Model

For four years, an investigation by Lighthouse examined welfare fraud detection algorithms across five European countries, revealing that many systems discriminate against vulnerable groups. In January 2023, they requested records from Amsterdam about a new model aimed at identifying potentially fraudulent welfare applications. The city complied quickly, revealing that the model was designed to be transparent and fair.

The model, an Explainable Boosting Machine (EBM), uses data to flag applications for further investigation based on 15 features, ensuring that demographic factors like gender or race were not directly included. However, the training data reflected biases from previous investigations, which may have led to unfair outcomes, particularly against non-Dutch applicants.

Amsterdam aimed to ensure fairness by testing how well the model worked across different demographic groups. They focused on minimizing false positive rates, meaning they wanted to ensure that different groups were flagged at equal rates. Initially, the model showed significant bias against applicants with migration backgrounds, prompting the city to attempt a “debiased” version by adjusting the training data.

After reweighting the data, the model performed better in terms of bias against non-Dutch applicants. However, during a pilot phase from June to August 2023, new biases emerged, with Dutch applicants being flagged more than before, and the model's overall performance declined. Consequently, the city decided to halt the pilot.

The investigation highlights the challenges of achieving fairness in AI. Adjusting one aspect of fairness can negatively impact others, creating trade-offs. The city’s focus on reducing false positives for one group inadvertently increased bias against another group, demonstrating the complexities involved in developing ethical AI systems.

The full analysis and related data are available on GitHub, indicating the importance of transparency and auditing in public sector algorithms, even under data protection constraints.

The author is disappointed with their experiences using coding chatbots and is looking for a better solution. They want to write a file with comments explaining what they expect the code to do, and then run a program that builds the code based on those descriptions. If the program needs to add extra code, it should comment on why it did so and explain what that code does.

The author prefers this approach to allow for a "literate programming" style, where the code is explained alongside its creation. They do not want an interactive chatbot that slows them down while they type, as they type quickly and accurately. Instead, they are looking for a tool that builds the code after they've finished writing.

They believe this solution is achievable and are seeking suggestions on how to create or find such a tool, as their previous experiences with existing chatbots and search engines have not been satisfactory.

The Final Cartridge III Freezer is a special cartridge for the Commodore 64 that allows users to pause games, apply cheat codes, and save the computer's state. This enhances the capabilities of the Commodore 64, contributing to its long-lasting popularity. The cartridge takes advantage of a feature called Ultimax mode, which makes the C64 compatible with certain game cartridges.

Here's how it works:

1. Freezing Process: When the freeze button is pressed, the cartridge sends a signal (NMI interrupt) that interrupts the C64's current task. However, it must carefully manage when to activate Ultimax mode to avoid issues with memory that may be turned off.

2. Challenges: There are technical difficulties, such as ensuring that the C64's memory is accessed correctly, and preventing errors caused by button bouncing (unwanted multiple signals when the button is pressed).

3. Memory Management: The cartridge operates with limited memory, using tricks to find available space for its functions. It backs up essential data (like register values) and can use memory for its operation without interfering with the running program.

4. Displaying the Menu: The cartridge utilizes a special mode of the C64's graphics system to display a menu without using much memory.

5. File Backups: The Final Cartridge III can create backups of the game state, which involves compressing memory data and writing it to disk or tape.

6. Game Trainer: It can also modify certain game functions by redirecting memory reads to its own code.

The creators of the Final Cartridge III demonstrated a deep understanding of the C64’s hardware and software, enabling innovative features despite the limitations of the system. Their work reflects the spirit of exploration and creativity that the Commodore 64 inspired in its users.

A recent question discusses whether Peano Arithmetic (PA) can prove that every Goodstein sequence eventually reaches zero. While PA can prove specific instances of this, it struggles with the general case. The post explores the relationship between PA and stronger systems, like Zermelo-Fraenkel set theory (ZF), and suggests that PA alone might not suffice for proving the broader statement about Goodstein sequences.

The discussion includes insights into how PA encodes computation and proofs, with references to concepts like ordinals and transfinite induction. The author argues that PA can extend its proof capabilities by incorporating the uniform reflection schema, which enhances its ability to prove Goodstein's theorem.

Overall, the post is a deep dive into the capabilities of PA in relation to Goodstein sequences, providing a blend of mathematical logic and programming perspectives.

The blog post by Avery Pennarun discusses the drawbacks of frequent reauthentication in security systems. Here are the key points:

1. Frequent Login Prompts Are Annoying: Constantly needing to log in interrupts work and frustrates users, potentially leading to weaker security habits.

2. Outdated Thinking: The belief that more authentication equals better security is incorrect. Security should focus on effective access management and real-time policy updates rather than frequent logins.

3. Real Security Measures: Effective security involves checking device possession and identity only when necessary, rather than on a fixed schedule. Automatic screen locks can help secure devices without annoying users.

4. Continuous Verification: Modern security should continuously verify access rather than relying on repeated logins. This can be done through background checks that update security attributes in real time.

5. Adaptive Security: Tailscale aims for smart, frictionless security that provides protection without disrupting users' workflows.

In summary, the article advocates for a shift from frequent reauthentication to smarter, less intrusive security measures that enhance user experience and maintain security.

Sperm, the tiny cells responsible for fertilizing eggs, remain a mystery despite centuries of research. Each man produces about 1,000 sperm per heartbeat, with millions released during intercourse, but only one typically fertilizes an egg. Key questions about how sperm swim, navigate, and fertilize eggs are still debated.

Recent studies using advanced methods have begun to reveal the journey of sperm from their creation in the testes to fertilization. Sperm are unique cells that require significant energy and can survive outside the body. They undergo dramatic changes in structure as they mature.

Historically, scientists have learned a lot about sperm, but many questions remain, particularly about their genetic complexity and how they interact with the female reproductive system. Sperm are guided to the egg by chemical signals, but the exact mechanisms of their navigation and fertilization process are still not fully understood.

Research has shown that sperm are influenced by the female reproductive tract, which evolves alongside them. There is also growing concern about declining sperm counts globally due to factors like pollution and lifestyle choices, contributing to male infertility, which affects roughly half of infertility cases.

Overall, the understanding of sperm biology is still developing, and further research is needed to address these mysteries and improve insights into male fertility issues.

The text discusses the history and implications of Zermelo's axiom of choice, which he introduced in the early 1900s to prove that every set can be well-ordered. Cantor initially proposed this idea, but Zermelo was the first to successfully demonstrate it by introducing the axiom of choice. This axiom sparked intense debate among mathematicians, with many opposing it due to its nonconstructive nature.

Despite initial resistance, the axiom gained acceptance because it became essential for the development of various mathematical fields, including set theory and topology. By the late 1930s, it was widely integrated into mathematical education.

However, intuitionists, like Brouwer, rejected the axiom, viewing it as nonconstructive and lacking motivation. There was a notable revival of interest in the axiom in 1967 when Bishop suggested that a choice function exists in constructive mathematics, implying that the concept of choice is inherent in the notion of existence.

Summary of “Language and Image Minus Cognition”: An Interview with Leif Weatherby

Leif Weatherby, an Associate Professor at NYU, discusses his upcoming book "Language Machines," which examines how Large Language Models (LLMs) have changed our understanding of language by separating it from cognition and computation. He critiques the concept of "remainder humanism," which he describes as a theoretical deadlock where scholars argue that while machines can mimic human tasks, humans are inherently superior. This perspective limits our understanding of LLMs and overlooks the complexities of language.

Weatherby contrasts various approaches to language: Chomsky's syntactical view, which sees LLM output as mere mimicry, and the statistical view, which claims LLMs produce indistinguishable human-like text. He argues for a structuralist perspective, where language is understood in a dynamic system of signs rather than just through reference or intent. He believes that LLMs reveal the underlying structures of language and call for a revival of literary scholarship in this area.

The interview also highlights the need for integrating structuralism with cognitive and data science to understand the relationship between language and computation. Weatherby asserts that LLMs offer new insights into language without equating machines with human intelligence. He calls for a collaborative approach across disciplines to harness the potential of AI in cultural studies, suggesting that this moment presents a significant opportunity for the humanities amidst the challenges posed by AI.

RAG, or Retrieval-Augmented Generation, is a popular approach in Generative AI (GenAI) that combines a user's prompt with dynamic information from external sources to improve responses from language models (LLMs). While RAG has gained traction for its ease of use and the rapid growth of RAG-based startups, it has significant drawbacks, especially for high-stakes applications in regulated industries.

Key Points:

1. RAG Definition: RAG enhances user prompts by integrating additional information, but it also allows LLMs to provide direct outputs, which can lead to unreliable or "hallucinated" responses.

2. Popularity Reasons:

   • Easy Prototyping: RAG systems can be quickly assembled using available open-source tools, making them attractive for demos.
   • Startup Investment: Many startups are focusing on RAG, leading to increased funding and interest in this area.
   • Influential Support: Key investors and analysts have promoted RAG, shaping its popularity.
   • Increased Research: The global research community is actively exploring RAG, contributing to its credibility.
   • Stagnant Search Technology: There has been little innovation in traditional search engines, making RAG an appealing alternative.

3. Concerns with RAG:

   • RAG can expose users to inaccurate LLM outputs, making it unsuitable for critical applications like finance or healthcare.
   • It mainly handles unstructured data, ignoring structured and semi-structured data crucial in many industries.

4. Alternatives: For high-stakes scenarios, Semantic Parsing is suggested as a better option, as it avoids some of the pitfalls associated with RAG.

In summary, while RAG is gaining popularity due to its ease of use and market interest, it is not reliable for high-stakes applications due to its tendency to produce inaccurate outputs. Alternatives like Semantic Parsing may be more suitable for those scenarios.

The text discusses a thought experiment where 100 people each have $100 and, every tick of the clock, each person randomly gives $1 to another person. Over time, this random process leads to unequal distribution of wealth, contrary to expectations of uniformity.

Key points include:

1. Wealth Inequality: The random giving process leads to some people becoming very rich while others become poor, illustrating how randomness can create significant disparities in wealth.

2. Graph Representation: The situation can be modeled as a random walk on a graph, where each state represents a possible distribution of money among the people. The graph isn't perfectly uniform, but most states resemble a regular graph.

3. Long-Term Distribution: In the long run, while most states are equally likely, it's likely that some individuals will end up with a lot of money, and many will be nearly broke.

4. Longest Piece Problem: The text also touches on the concept of random distributions by comparing the situation to a well-studied problem in probability regarding the lengths of pieces when breaking a stick at random points.

5. Implications of Giving Less Money: If each person only has $1, the likelihood of someone being broke increases significantly, affecting how wealth is distributed even more dramatically.

Overall, the experiment reveals how random interactions can lead to persistent inequalities despite an initial equal starting point.

The author shares their struggle with procrastination and how they found a solution by understanding the addictive nature of video games. They built a successful business but faced burnout and bankruptcy due to reliance on stress to get work done. By analyzing what makes video games engaging, the author realized their focus could also be applied to other tasks.

Key points include:

1. Understanding Game Loops: Video games, especially first-person shooters, use quick loops of action and immediate feedback to keep players engaged. This feedback creates a state of flow and releases dopamine, making tasks feel enjoyable.

2. Applying the Game Loop to Tasks: To overcome procrastination, the author suggests breaking tasks into smaller, manageable parts and using sticky notes for visual feedback. Completing each small task provides a sense of accomplishment.

3. Daily Routine and Momentum: Starting the day with simple tasks creates momentum, making it easier to tackle more challenging tasks later. Preparing sticky notes the night before helps streamline the morning routine.

4. Using a Receipt Printer: To enhance productivity, the author adopted a thermal receipt printer to print daily tasks, eliminating the time spent writing sticky notes. This system improved consistency and efficiency, allowing for more tasks to be completed.

5. Custom Software: The author developed software to manage tasks more effectively, allowing for quick adjustments and an organized view of tasks and subtasks.

Overall, the combination of breaking tasks down, utilizing visual feedback, and incorporating technology has significantly improved the author’s productivity, particularly in managing ADHD. They encourage readers to try these methods and plan to share their software publicly in the future.

Summary of HTML Spec Change: Escaping < and > in Attributes

On May 20, 2025, the HTML specification was updated to require that the characters < and > are escaped in HTML attributes. This change aims to enhance security by preventing mutation XSS (mXSS) vulnerabilities. It will be implemented in Chrome 138 on June 24, 2025.

Key Changes:

• When accessing the outerHTML of an element, attributes containing < or > will now show these characters as < and >.
  • For example, <div data-content="<u>hello</u>"></div> will now be represented as <div data-content="&lt;u&gt;hello&lt;/u&gt;"></div>.
• This change only affects how HTML is serialized (turned back into a text format) and does not alter how HTML is parsed or accessed using DOM APIs like getAttribute or dataset, which will still return the original values.

What Might Break:

• Using innerHTML or outerHTML to extract attribute values may lead to unexpected results since the output will now include escaped characters.
• End-to-end tests comparing generated HTML to static values may fail if < or > are present in attributes, requiring updates to the expected values.

Impact:

• Developers need to adjust their code and tests to accommodate this change for better security against certain vulnerabilities.

The change will also be available in Firefox 140 and Safari 26 Beta. For issues arising from this change, users are encouraged to report them on the Chromium bug tracker.

Many online scammers are using clever tactics to trick people, including fake unsubscription links in emails. While most legitimate emails provide a way to unsubscribe, clicking on these links can pose security risks as they take you out of your email client and onto the open web.

Experts warn that about 1 in 644 unsubscribe links could lead to harmful sites, and scammers often use these links to confirm that your email address is active. This can make you a target for future spam or phishing attempts. A safe practice is to avoid providing personal information, like passwords, after clicking an unsubscribe link.

To stay safe, consider using "list-unsubscribe headers," which are safer because they keep your actions within your email client. If that option isn't available, you can mark emails as junk or use dummy email accounts to protect your primary email. Although it may be tough to eliminate unwanted emails completely, these steps can help maintain your digital privacy.

Summary: Rendering Crispy Text On The GPU

The article discusses advancements in real-time text rendering using the GPU, focusing on overcoming issues with previous methods like Multi-Channel Signed Distance Fields (SDFs). The author found SDFs unsatisfactory due to problems with quality, atlas size, flexibility, and complexity.

Key Improvements:

• The author experimented with subpixel anti-aliasing to enhance text clarity, especially on non-standard OLED monitors that exhibit fringing issues.
• The new approach involves directly using the vector curves that define glyphs, rasterizing them in real-time instead of pre-baking them into textures. This method reduces memory usage and improves quality at various resolutions.

Rendering Process Overview:

1. Bezier Curves Processing: Glyph curves are loaded and converted to quadratic Bezier curves for easier rendering.
2. Coverage Calculation: A ray tracing method is used to determine pixel coverage by intersecting rays with the curves.
3. Curve Access Optimization: Glyphs are split into horizontal bands to reduce the number of curves checked during rendering.
4. Atlas Packing: An atlas is created to store glyphs, allowing reuse and minimizing the need to render the same glyph multiple times.
5. Temporal Accumulation: Samples are accumulated over frames to refine the quality of the rendered glyphs progressively.

Subpixel Anti-Aliasing: This technique utilizes the individual RGB subpixels of displays to enhance text rendering quality, especially important for monitors with unconventional subpixel layouts. The author emphasizes the need for software to adapt to varying subpixel structures for better results.

Conclusion: The pursuit of high-quality text rendering is crucial for user interfaces, as it greatly affects user experience. The author encourages further exploration and innovation in glyph rendering techniques.
