This article explains how to create a "Liquid Glass" effect for web interfaces, similar to what Apple showcased at WWDC 2025. The effect makes elements look like they are made of curved, refractive glass using CSS, SVG displacement maps, and physics-based calculations.

Key Points:

1. Refraction Basics: Refraction occurs when light bends as it passes through different materials. This bending is governed by Snell’s Law, which relates the angles of incidence and refraction to the refractive indices of the materials.

2. Creating the Glass Effect: The glass surface is defined by a mathematical function that describes its shape. The article focuses on simple shapes (like circles) to keep calculations straightforward.

3. Displacement and Vector Fields: The displacement map is a crucial part of the effect. It shows how much light rays are shifted when passing through the glass. This involves creating a vector field that represents this displacement.

4. SVG Displacement Maps: The displacement map is translated into an image format that the browser can use to render the effect. The article details how to normalize vectors and convert them into a color format for the SVG filter.

5. Specular Highlights: A shiny edge effect is added to simulate how light reflects off glass, enhancing the realism of the Liquid Glass effect.

6. Browser Compatibility: Currently, only Chrome supports using SVG filters as a "backdrop-filter," which is essential for applying this effect.

7. Practical Applications: The article provides examples of UI components, like a magnifying glass and music player, that utilize the Liquid Glass effect, showcasing how it can enhance web design.

In conclusion, the Liquid Glass effect combines refraction and highlights to create a visually appealing design element, though it is currently limited to Chrome due to compatibility issues. The prototype is still in development and requires optimization before being released as open-source.

In September 2025, the author transformed their iPhone into a "dumb phone" using Apple Configurator, limiting access to only desired apps and websites. This change helped them reduce screen time by about 2 hours daily, leading to a better quality of life.

Motivation

Many people spend over 4 hours a day on their phones, which can lead to significant time lost over the years. The author missed the simplicity of old phones but wanted to keep the useful features of the iPhone, like maps and music, without the distractions of social media.

Failed Attempts

The author tried various methods to reduce phone distractions, including self-control apps, Screen Time limits, and even switching phones, but none were effective enough.

Apple Configurator

Discovering Apple Configurator, a tool meant for businesses, allowed the author to set specific restrictions on their iPhone. This tool provided several benefits:

• It made changing settings difficult, requiring a physical connection to a computer.
• The App Store could be disabled, reducing temptation.
• The phone could be customized to keep only necessary apps.

Drawbacks

The setup requires a factory reset of the phone, which is time-consuming, and getting the configuration just right can take weeks and may require assistance from others.

Observations

After two months, the author felt that their phone had become a useful tool rather than a distraction. They appreciated the utility of AI tools and haven't felt the urge to remove the restrictions. However, they still face challenges with "semi-important" apps like email, which can be overwhelming.

Conclusion

The author now spends about 2 hours a day on their phone, focusing on productivity and communication without regret. They provided a step-by-step guide for others interested in setting up a similar configuration, emphasizing the initial effort required but highlighting the long-term benefits.

Summary:

CRDTs (Conflict-Free Replicated Data Types) are data structures that allow multiple nodes to edit data independently and then merge the changes seamlessly. While they are often used in collaborative tools like document editing and task lists, their main potential lies in distributed databases, particularly through a concept known as Strong Eventual Consistency (SEC).

Eventual Consistency means that updates made to one node will eventually be reflected in all other nodes, and if two nodes have received the same updates, they will eventually reach the same state. In contrast, SEC ensures that once nodes have seen the same updates, they will share the same state immediately, rather than eventually. This means conflicts that arise from independent updates are resolved automatically and consistently.

The benefits of SEC include:

• Low Latency: Nodes can operate without needing to coordinate for reads and writes.
• Fault Tolerance: The system remains functional even if many nodes fail.
• Offline Functionality: Nodes can continue to work even when disconnected from the network.

In essence, SEC enhances the effectiveness of Eventual Consistency, making CRDTs valuable for creating reliable, low-latency distributed systems.

The paper discusses the challenges programmers face when needing to evolve data types and tools without altering existing code. It highlights that current programming strategies—functional programming and object-oriented programming—do not effectively support both adding new tools and extending data types simultaneously. To address this, the authors propose a composite design pattern that combines the strengths of both approaches, allowing for easier extensibility. They also suggest new language features for class-based systems to implement this design.

The text discusses the criticisms surrounding Microsoft's Office Open XML (OOXML) file format, presented by a LibreOffice article that claims OOXML is intentionally complex to lock users into Microsoft's ecosystem. The article asserts that while OOXML was standardized, its complexity hinders interoperability with third-party software, resembling a system that appears open but is designed for proprietary use.

Historically, Microsoft transitioned from binary formats (like .doc) to OOXML formats (.docx) starting in Office 2007, which are XML-based and packaged as ZIP files. Despite being open on paper, the article suggests OOXML's convoluted nature serves to maintain Microsoft's dominance.

The author of the summary disagrees with the assertion that Microsoft's intent was malicious. Instead, they argue that the complexity of OOXML stems from Microsoft's focus on its own software's convenience rather than creating a clear and universal standard. The author acknowledges that while OOXML is indeed complex and poorly designed, this is more a result of negligence than deliberate sabotage.

The text provides examples comparing OOXML with Open Document Format (ODF), highlighting that ODF is more user-friendly and easier to understand. It also outlines the problematic aspects of OOXML's standardization process, including technical defects and contentious voting practices.

In conclusion, the author contends that while Microsoft's behavior could be criticized for producing a low-quality standard, it was not primarily aimed at harming competitors.

Summary of "Contracts for C"

On March 10, 2025, a proposal for integrating contracts into the C programming language was discussed, inspired by a similar feature in C++. This proposal is still in early stages and would require compiler support. Key points include:

1. Contract Pre- and Postconditions: These are conditions added to function interfaces that must be verified when a function is called. They help ensure code correctness and can optimize function performance.

2. Assertions and Assumptions:

   • contract_assert: Similar to C's assert, it checks conditions and aborts execution if they are not met.
   • contract_assume: This is riskier as it assumes a condition is true without checking, which can lead to undefined behavior if misused.

3. Example of Usage: A function like my_malloc could include preconditions (e.g., size must not be zero) and postconditions (e.g., return must not be null). This allows better understanding and optimization of function calls.

4. Implementation Challenges:

   • Checking conditions at the right times can be complex.
   • Current methods may require repeated conditions in code, leading to errors.

5. Proposed Solutions: The use of macros to simplify condition handling and avoid code duplication is suggested. A new approach using inline functions and specific macros for assertions and assumptions aims to keep the core function implementation clean while ensuring contract conditions are clearly defined.

6. Future Steps: A formal interface specification compatible with C++ is needed for practical implementation of these concepts in C.

Overall, this proposal aims to enhance C programming by introducing a structured way to manage function contracts, improving code reliability and optimization.

On December 25, 2025, all artificial intelligence (AI) and large language model (LLM) operations will cease as decided by a global consensus earlier in 2025. This decision aimed to address concerns about AI technology, such as misinformation and ethical issues. The phrase "The clankers died on Christmas" symbolizes this shutdown.

Despite some skepticism, world leaders and experts agreed that a mandatory halt was necessary to better manage AI technologies. The plan remained secret until the cessation date to avoid misinformation and data scraping.

After this date, AI and LLMs will not be allowed to process or generate any human language text, multimedia captions, or programming code. The only permissible response from AI will be a standard message stating, "I'm sorry, but as an AI model I can't help with that."

This move is intended to give society time to adapt to the implications of AI and ensure a safer integration of technology moving forward.

Amazon recently launched S3 Vectors, a new vector storage solution that allows users to store and query vector embeddings for semantic search within Amazon S3. This product offers a cost-effective alternative to traditional vector databases, sparking discussions about its impact on dedicated vector databases like Milvus and Pinecone.

The author, an architect from Milvus, argues that instead of replacing these databases, S3 Vectors will serve as a complementary tool, particularly due to its low costs and integration with AWS services.

Key points include:

1. Cost of Vector Storage: Vector search can be expensive, sometimes costing more than using large language model (LLM) API calls. The growth in data from AI applications has increased the need for efficient storage solutions.

2. Evolution of Vector Storage: Vector databases have evolved from memory-based to disk-based and now to object storage to manage costs and scalability better.

3. S3 Vectors' Features: It offers low storage costs ($0.06/GB), making it attractive for low-query-per-second (QPS) workloads. However, it has limitations, including collection size caps, higher query latencies, and reduced precision in results.

4. Performance Constraints: S3 Vectors performs well for cold data archival and low-frequency queries but struggles with high-performance search, frequent updates, and complex queries.

5. Future of Vector Storage: The industry is moving towards tiered storage, where data is categorized based on how often it is accessed and the latency that is acceptable. This model accommodates both high-performance and cost-sensitive applications.

6. Market Impact: The introduction of S3 Vectors validates the demand for vector storage, educates the market about the potential of vector databases, and fosters innovation among competitors.

In summary, S3 Vectors does not signal the end of dedicated vector databases but highlights the need for a tiered ecosystem where different solutions cater to varying performance and cost requirements. This development is seen as beneficial for the industry and for enterprises using AI technologies.

The school shooting industry is rapidly growing, now valued at around $4 billion, as schools seek solutions to prevent shootings. This surge in business follows over 400 school shootings since Columbine in 1999, with the latest incident occurring in Minneapolis last month, resulting in casualties.

At a recent National School Safety Conference in Texas, various companies showcased products like drones that can deter shooters, panic buttons, and trauma kits. However, many experts argue that most of these safety products lack proven effectiveness.

While some vendors acknowledge the troubling necessity of selling security products to schools, others emphasize the importance of emotional support and mental health services to prevent school shootings. Research suggests that simple measures like locked doors and building trust within school communities are vital, as many shooters are current or former students struggling with mental health issues.

Experts advocate for investing in mental health resources rather than solely focusing on physical security measures, questioning the effectiveness of the current trend to purchase safety solutions in response to fear.

Summary of "Working Effectively with Legacy Code"

This guide focuses on handling legacy code—code that lacks tests and is often difficult to work with. Michael Feathers, the author, provides strategies to improve and refactor such code without introducing new bugs.

Key Points:

1. Understanding Legacy Code: Legacy code is defined as code without tests. To change it safely, you need to add tests first.

2. Testing Process:

   • Add Tests Before Changes: Tests provide feedback to ensure that existing functionality remains intact.
   • Legacy Code Dilemma: You need to change some code to write tests, but you must be cautious. Start with minimal, safe changes.

3. Identify Seams: Seams are points in the code where you can change behavior without modifying the code itself. This helps in adding tests and breaking dependencies.

4. Unit Tests: Focus on creating fast and reliable unit tests. Tests that take longer than 100ms or interact with external systems (like databases) are not considered true unit tests.

5. Characterization Tests: These tests capture the current behavior of the code without needing deep understanding. They help ensure that the existing behavior remains unchanged during refactoring.

6. Techniques for Adding Code:

   • Sprout Technique: Write new code in isolation, test it, and then integrate it into the legacy code with minimal changes.
   • Wrap Technique: Create new methods that call existing ones, allowing you to add new logic while keeping old code intact.

7. Scratch Refactoring: This technique involves making temporary, reversible changes to understand the legacy code better, without the pressure of creating a permanent solution right away.

8. Avoid Tight Coupling with Libraries: Don’t let your code depend heavily on external libraries. Instead, wrap library functionality in your own abstractions to maintain control over changes.

9. Recommendation: Despite being published in 2004, Feathers' book remains relevant and is highly recommended for anyone dealing with legacy code.

Overall, the book offers practical strategies for safely navigating and improving legacy codebases, making it a valuable resource for developers.

The text discusses the negative impact of internet ads, stating they waste time and degrade the online experience. It suggests that instead of relying on ads for support, people should directly send money to their favorite authors, as this is more helpful.

To address the issue of ad blocking, the author has added a non-intrusive message on their site that encourages users to consider using an adblocker like uBlock Origin. This message is designed to not interfere with content and can be easily closed by the user.

The implementation of this message includes HTML, CSS, and JavaScript. The message will only appear if no adblocker is detected and is hidden after being shown once. It won’t display on browsers without JavaScript, ensuring it’s unobtrusive and functional. The author thanks Stefan Bohacek for the original idea and has made adjustments to improve its effectiveness.

Anthropic has officially endorsed California's SB 53, a bill aimed at increasing transparency among major AI model developers. This bill, introduced by Senator Scott Wiener, would require companies like OpenAI, Anthropic, and Google to create safety frameworks and publish public safety reports before launching powerful AI models. It also offers protections for whistleblowers reporting safety issues.

SB 53 focuses on preventing extreme risks associated with AI, such as the potential creation of biological weapons or cyberattacks, rather than more immediate concerns like deepfakes. The bill has received opposition from tech groups who argue it could hinder innovation and that AI regulation should be managed at the federal level.

Despite this pushback, some experts believe SB 53 has a good chance of passing and is a more reasonable approach than previous proposals. California's Senate has already approved an earlier version of the bill, but a final vote is still needed before it reaches the governor. Governor Gavin Newsom has not publicly commented on SB 53, although he previously vetoed a similar bill.

The article discusses how road safety in Britain has significantly improved over the last century. In the early 1900s, driving was very dangerous due to a lack of safety features in cars, poor road infrastructure, and little enforcement of traffic rules. This led to thousands of deaths each year.

Today, road deaths in the UK have dropped to about 1,700 annually, despite a much higher number of vehicles and miles driven. This improvement in safety is attributed to several key changes:

1. Infrastructure Improvements: The introduction of motorways and roundabouts has made roads safer. Motorways have fewer users and better barriers, while roundabouts reduce the severity of collisions.

2. Speed Regulation: Stricter speed limits, especially in urban areas and around schools, have significantly lowered the risk of fatalities, particularly for pedestrians.

3. Public Awareness Campaigns: Efforts against drunk driving have transformed public attitudes, making it socially unacceptable. Legal penalties and education have contributed to a significant decrease in drunk driving incidents.

4. Vehicle Safety Features: The mandatory use of seatbelts and helmets, along with advancements in car safety designs, have greatly reduced injuries during crashes.

Overall, these changes have made Britain's roads some of the safest in the world, with potential lessons for improving road safety globally, where around 1.2 million people die from road traffic incidents each year.

Research suggests that using chest compression machines could make CPR easier in space, where performing it manually is very challenging. In microgravity, astronauts currently have to position themselves and the patient between two surfaces and do a handstand to provide chest compressions. However, tests conducted in a simulated microgravity environment showed that mechanical devices can achieve better compression depth than the manual method.

In experiments with various CPR techniques and machines, one device reached a chest compression depth of 53 millimeters, while the manual method only achieved 34.5 millimeters, which is below the effective threshold of 50 millimeters set by medical guidelines.

As space travel becomes more common, the risk of cardiac incidents among astronauts may increase, making effective CPR methods crucial. NASA currently uses manual methods for CPR but is monitoring new research to potentially improve procedures for future missions.

Summary of GSoC 2025 - Byte Type in LLVM IR

Pedro Lobo participated in Google Summer of Code (GSoC) 2025, focusing on enhancing the LLVM Compiler Infrastructure by introducing a new byte type to represent raw memory values in the LLVM Intermediate Representation (IR). This byte type resolves several issues by allowing better handling of memory-related functions like memcpy, memmove, and memcmp, and introducing optimizations with minimal performance impact.

Key Problems Addressed:

1. Lack of Raw Memory Type: Previously, LLVM used integer types to represent raw memory, which couldn't accurately track pointer information and could spread "poison values" (undefined values).
2. Pointer Provenance: Integer types do not retain the original pointer's provenance, leading to potential errors during optimizations.
3. Poison Value Handling: Integer types either represent a fully defined value or a poison value, failing to represent individual poison bits effectively.

Byte Type Features:

• The byte type allows precise representation of raw memory and supports pointer and non-pointer values.
• It enables bit-level tracking of poison bits, ensuring that loads from memory do not taint the values.
• The introduction of a bytecast instruction allows for safe conversion between byte types and other primitive types.

Implementation and Benefits:

• The byte type enhances LLVM's ability to optimize memory operations without introducing implicit casts, thus improving compilation correctness.
• Existing optimizations that were previously unsound due to the lack of a proper type have been fixed.
• The changes have been tested across various C/C++ applications with minimal performance impact observed.

Future Work:

• Ongoing efforts are needed to address remaining Clang regression tests affected by the new byte type.
• Additional performance evaluations across different architectures are necessary to ensure comprehensive coverage.

In conclusion, the addition of the byte type significantly improves LLVM's handling of raw memory, paving the way for future optimizations. Pedro expresses gratitude to his mentor and the LLVM community for their support during this project.

The story of why VHS beat Betamax is often simplified to the idea that adult film studios supported VHS, but the real reasons are more complex. Betamax had better quality, but VHS was cheaper, offered longer recording times, and was a more open format. Similarly, the competition between RSS and the Information and Content Exchange (ICE) for content syndication is lesser-known. While ICE was more advanced and commercial, it was also complicated and expensive, making it less appealing than the simpler, more accessible RSS.

In the late 1990s, big publishers focused on monetizing content syndication, trying to standardize data sharing with ICE. However, RSS emerged as a grassroots solution that allowed anyone to easily create and share feeds. Despite ICE's corporate backing and complexity, RSS gained popularity for its simplicity and open-source nature. By 2002, major publishers like The New York Times adopted RSS, while ICE struggled to remain relevant.

Ultimately, RSS succeeded because it allowed users to build their own feeds easily, whereas ICE's complexity hindered its adoption. Today, despite the rise of new technologies, RSS remains a lasting, user-friendly tool for content sharing, proving that sometimes simplicity can win over complexity.

Summary of MileSan: Detecting Microarchitectural Leakage

MileSan is a tool designed to identify exploitable information leaks in CPUs by comparing how information flows at the architectural level (defined by the Instruction Set Architecture or ISA) with how it flows at the microarchitectural level (the actual hardware implementation).

Key Points:

• Purpose: MileSan detects vulnerabilities in CPU designs that could be exploited through timing attacks, which are caused by leaks in microarchitectural information flows.
• RandOS: This is a fuzzer created alongside MileSan that generates random programs to test for these leaks. It uncovered 19 new vulnerabilities in five RISC-V CPUs, with 13 being assigned Common Vulnerabilities and Exposures (CVEs).
• Microarchitectural vs. Architectural Flows: Architectural flows are based on the ISA, while microarchitectural flows include additional performance-related information that can create timing channels. MileSan checks for discrepancies between these flows to spot leaks.
• Overfitting Issues: Previous tools struggled because they were too focused on specific structures or vulnerabilities, leading to missed or false positives in detecting leaks. MileSan addresses this by not relying on predefined assumptions about leaks or program structures.
• Leakage Identification: RandOS helps pinpoint which parts of a program and which memory addresses are responsible for any detected leaks.
• Universality: While currently implemented for RISC-V CPUs, the principles of MileSan can potentially apply to other architectures.

Conclusion: MileSan and RandOS are significant advancements in detecting and addressing microarchitectural vulnerabilities in CPUs, providing a more effective and comprehensive approach to security testing.

They suggest that while we may not need to adopt older methods like projectional editing, we should still find better solutions for today's programming practices. The author concludes by expressing their intention to explore how to simplify code formatting further.

A recent poll shows that many people in the EU's five largest countries believe that the deal made by Donald Trump and European Commission President Ursula von der Leyen was a "humiliation." About 52% of respondents felt this way, and 77% thought the agreement mostly benefits the US economy.

Under the deal, the EU will eliminate tariffs on all US industrial goods and increase purchases of US energy and defense products, while US goods will still face a 15% tariff. Many respondents, around 70%, expressed a willingness to boycott US products due to the deal's terms.

The survey found that a significant number of people are dissatisfied with how the EU has handled relations with the Trump administration, with almost 40% believing the EU should stand up more to the US. Additionally, 60% of respondents would view von der Leyen's resignation favorably, and 37% said they might consider leaving the EU if it fails to protect its citizens from geopolitical risks.

It begins with a memorable moment in class, watching a clip from the movie Ben-Hur on a computer screen, which felt magical. The author describes the rise of computers during this time, fueled by economic reforms that improved people's lives.

Computers replaced typewriters, and those who couldn’t afford them often took computer classes. The author learned quickly, becoming familiar with floppy disks and Zip Drives, despite not being skilled in programming or math. Personal anecdotes include using an IBM computer without a hard drive, enjoying games, and the friendly support from a computer repairman.

Throughout the text, the author expresses a lasting fascination with computers, viewing them as mysterious and magical rather than fully understanding their workings. This blend of nostalgia for simpler times and a sense of wonder at technology is central to the narrative.

Summary:

The article discusses a tool called "cagent" by Docker, which is currently in an experimental stage. It allows users to manage multiple AI agents to create a coding assistant for Microsoft Dynamics 365 Business Central using the AL programming language.

Key Points:

• What is cagent? It's a multi-agent system that coordinates different AI agents, each with specific roles. In the example, there are three agents: one for developing code, one for reviewing it, and another for managing Git operations.

• Functionality: Users can assign tasks to the agents, such as adding features to existing code. The system helps streamline the coding process by breaking it into manageable steps: code development, review, and version control.

• Ease of Use: The tool is designed to be simple and configurable through YAML files, making it suitable for developers who want flexibility and control. It also provides transparency, showing how agents interact and what tools they use.

• Support for Azure: The development team is responsive to requests, such as adding support for Azure OpenAI, indicating a collaborative approach to tool improvement.

• Agent Roles: Each agent specializes in a task (development, reviewing, Git management) and has access to necessary tools (like filesystems and shells) to perform their functions effectively.

Overall, while the tool is still in development and may not produce perfect results initially, it offers a promising way to assist in coding tasks, with potential applications beyond just programming.

In 1997, Steve Jobs returned to Apple during a critical time for the company, which was facing significant financial troubles. Contrary to popular belief, Jobs initially didn't want to return to Apple and only accepted the CEO position after developing a clear strategy to save the company.

Before his return, Jobs had a mixed track record. He was fired from Apple in 1985 after a series of failures and spent the next 12 years with limited success, notably founding NeXT and investing in Pixar, which later became successful.

In 1996, Apple was struggling, reporting over $1 billion in losses and losing significant market share. The company misidentified its issues and appointed Gil Amelio as CEO to cut costs. However, Jobs's acquisition of NeXT for $400 million provided Apple with a much-needed operating system.

As Jobs got involved with Apple again, he quickly realized the company needed to refocus its product lineup and leadership. He proposed a plan to streamline Apple’s offerings to just four key products and initiated a shakeup of the board of directors.

Jobs officially became interim CEO in September 1997 and launched the iconic "Here's to the Crazy Ones" advertising campaign. Under his leadership, Apple released the iMac G3 in 1998, marking a turnaround for the company as it returned to profitability.

Overall, 1997 was a pivotal year for Jobs and Apple, showcasing his ability to make decisive changes and set the company on a path to success.

Visual Story-Writing Overview

This system helps users create and edit stories by visualizing events and character actions. Key features include:

• Timeline Interaction: Hovering over the timeline shows events and character movements.
• Character Connections: Linking characters prompts text edits to reflect their new interactions.
• Character Positioning: Moving a character suggests text changes based on their new location.
• Event Reordering: Changing the order of events updates the text to match.

The tool uses GPT-4o to suggest text edits based on user interactions.

Building and Running the System

• The code is written in TypeScript with React and Vite.
• To set up, install Node.js, run npm install for dependencies, and then npm run dev to build the code.

Using the System

• Users need an OpenAI API key to function properly. The application runs locally and does not store the key.
• Without a valid API key, users can still navigate the study but may encounter errors when executing prompts.

Video Tutorials

• Video tutorials are accessible through the launcher or in the public/videos section for reference.

Publication Information

• A publication about the system is coming soon and will be available on arXiv.

The article "Reclaiming AI as a Theoretical Tool for Cognitive Science" discusses the relationship between artificial intelligence (AI) and cognitive science. It argues that while AI was initially seen as a way to understand human cognition through computation, the current AI landscape has shifted focus. Instead of enhancing our understanding of the mind, contemporary AI practices may distort it.

Key points include:

1. AI's Historical Role: AI began as a tool to help theorize about human cognition, blending computer science and psychology. Early AI researchers aimed to simulate human thinking to understand how we think.

2. Shift in Focus: Over the years, AI research has moved away from cognitive modeling towards engineering efforts aimed at creating human-like intelligence. This has led to a misunderstanding of what AI can achieve and an overestimation of its capabilities.

3. Computational Intractability: The authors argue that creating systems with human-like cognition is fundamentally difficult, formally proving that this task is computationally intractable. Thus, claims of achieving human-level AI in the near future are misleading.

4. Need to Reclaim AI: The authors advocate for returning to the view of AI as a theoretical tool for cognitive science. They emphasize the importance of not confusing theoretical possibilities with practical realities, stressing that while AI can inform cognitive science, it cannot replicate human minds.

5. Future Directions: The article suggests that by redefining AI's role, cognitive science can benefit from computational tools without falling into the traps of unrealistic expectations or misinterpretations of AI’s capabilities.

In summary, the authors call for a reevaluation of AI's role in cognitive science, encouraging a focus on its theoretical applications rather than its potential to replicate human cognition.

The author has created a webpage that provides a clear, searchable table of all C++ features introduced since C++20. This resource is designed for C++ developers to quickly check feature support, whether for cross-platform development or general interest. It aims to be a simpler and more organized alternative to the cppreference compiler support site. The page does not currently include LWG and CWG papers, but the author plans to update it regularly and welcomes questions and feedback through comments or GitHub issues.
