On February 9, the European Commission introduced new rules under the Ecodesign for Sustainable Products Regulation (ESPR) to stop the destruction of unsold clothing, accessories, and footwear. These measures aim to reduce waste, lower environmental impact, and support companies that adopt sustainable practices.

Each year, 4-9% of unsold textiles in Europe are destroyed, contributing to 5.6 million tons of CO2 emissions. The new regulations require companies to report how much unsold stock they throw away and prohibit the destruction of unsold apparel, except in specific circumstances like safety concerns.

The rules will take effect for large companies on July 19, 2026, and for medium-sized companies by 2030. Companies are encouraged to find alternatives to disposal, such as reselling or donating unsold goods. The ESPR aims to promote durability, recyclability, and efficiency in products sold in the EU, helping to create a more sustainable circular economy.

Recent advancements in foundational models have led to the creation of reasoning systems that can perform at a high level in mathematics, similar to top competitors in the International Mathematical Olympiad. However, moving from solving competition problems to conducting professional research involves dealing with extensive literature and complex proofs.

In this context, we present Aletheia, a math research agent that can generate, verify, and revise solutions using natural language. Aletheia uses an advanced version of Gemini Deep Think for difficult reasoning tasks, a new method for scaling inference beyond Olympiad-level challenges, and various tools to tackle mathematical research complexities.

Aletheia has demonstrated its capabilities through various milestones, including:

1. An AI-generated research paper on structure constants in arithmetic geometry, created without human help.
2. A collaborative research paper where humans and AI worked together to prove bounds in systems of interacting particles.
3. A semi-autonomous evaluation of 700 open problems related to Bloom's Erdos Conjectures, which included solving four open questions independently.

To improve public understanding of AI developments in mathematics, we recommend measuring the levels of autonomy and novelty in AI results and introduce the idea of human-AI interaction cards for greater transparency. We conclude by reflecting on the collaboration between humans and AI in mathematics and provide access to all related prompts and outputs at a specified URL.

Summary of Gwtar: A Static Efficient Single-File HTML Format

Gwtar is a new HTML archival format designed to create a single, self-contained HTML file that can efficiently load large assets only as needed. It uses a JavaScript header to manage HTTP range requests, allowing browsers to download only the parts of the file necessary for display.

Key Features:

1. Polyglot Format: Gwtar combines HTML and a tarball of assets into one file, achieving three important properties: being static (self-contained), a single file, and efficient (lazy-loading).
2. Efficient Loading: Instead of downloading everything at once, Gwtar lets users access only the required assets, which is especially useful for large media files.
3. User-Friendly: The format is designed to be compatible with standard web browsers, requiring no special server support, making it easy for users to view and share archived content.

Background and Motivation: Gwtar was created to address the problem of link rot and the limitations of existing HTML archival formats. Many formats fail to achieve all three desired properties of being static, a single file, and efficient.

Technical Aspects:

• Gwtar files start with a header containing JavaScript that manages asset loading and stops the browser from downloading unnecessary data.
• Assets are stored in a tarball following the header, which can include various file types and is designed to be referenced efficiently.
• Gwtar supports optional features like forward error correction (FEC) for data recovery and cryptographic signing for integrity.

Limitations:

• Local viewing can be problematic due to browser security restrictions.
• Some servers may not support range requests, impacting efficiency.
• Cloudflare, a popular CDN, can strip range request headers, requiring Gwtar files to use a special MIME type to function correctly.

Future Improvements: Potential updates could include enhanced validation, built-in compression, and better support for multiple pages or deduplication of assets.

In essence, Gwtar aims to provide a robust and user-friendly solution for archiving HTML content while overcoming the challenges posed by existing formats.

New York City’s public hospital system, known as Health and Hospitals Corporation, has paid nearly $4 million to Palantir since 2023. Palantir is a data analysis company that works with U.S. Immigration and Customs Enforcement (ICE) and the military, which has raised concerns among activists. They argue that it is inappropriate for a company involved in immigration enforcement to also provide software for hospitals.

Palantir’s software is used to improve billing processes, including automated scanning of patient records to increase charges for hospital services. Critics worry that sharing any patient data with Palantir could risk personal information being exposed or used against immigrants.

Activists, including members from the New York Civil Liberties Union, have called for the city to end its contract with Palantir, stressing that it puts vulnerable communities at risk. They argue that every New Yorker deserves access to healthcare without fear of their information being shared with federal authorities.

The mayor's office, which influences the hospital system's operations, has not publicly commented on the situation.

Since December 2017, it has saved over 200,000 pieces of content from various web technologies. The project provides software tools for easy access and playback of this preserved content, including a launcher, a proxy for web games, and a secure playback environment, all of which are open-source.

Started by BlueMaxima to combat the loss of web games after Flash's decline, Flashpoint has grown to involve many contributors worldwide. It operates as a non-profit, aiming to make these digital experiences accessible. Supporters can donate or learn more about the project’s funding on their website.

The text describes a lightweight web design, featuring only 6KB of CSS and 2.2KB of JavaScript. Both files are minimized and compressed for efficiency.

Palantir Technologies, a US data analytics firm, is suing the Swiss magazine "Republik" over claims of "significant inaccuracies" in its reporting. After failing to obtain a counterstatement from the magazine, Palantir is now pursuing legal action to enforce one. This move has unexpectedly increased attention on "Republik" and generated public support for the small outlet.

Palantir argues that the magazine's articles misrepresent its interactions with Swiss authorities related to military, police, and health sectors, despite no business deals being finalized. The company emphasizes that it respects press freedom but believes it deserves a chance to correct what it sees as misinformation.

Swiss law allows for counterstatements, which can be requested when a publication refuses to correct its claims. However, this process does not determine the truth of the statements in question. "Republik" maintains that its research is thorough and based on official documents.

Palantir faces challenges in establishing itself in Europe, partly due to its controversial connections in the US, and has recently been criticized for its operations in Israel. Despite the ongoing legal battle, "Republik" has experienced a surge in support from its readership.

Summary of Starflight and Its Reverse Engineering Project

What is Starflight? Starflight is a video game from the 1980s by Binary Systems, where players act as a starship captain exploring the galaxy. The game allows for various activities like mining, combat, and diplomacy, with an overarching story about an ancient race causing star flares. It is considered one of the first sandbox games and has influenced many others.

About the Project The author, who wanted to play Starflight as a child but couldn't due to language barriers, revisited the game years later and enjoyed its exploration and storytelling. This project involves reverse engineering the game to understand its design and the developers' thought processes. Starflight is written in Forth, a minimalist programming language, making traditional analysis tools ineffective.

Understanding Forth Forth is unique in its syntax, using a stack-based approach where commands are written in a simple format. For example, to add two numbers, it would look like "2 3 +". This minimalistic style allows for efficient coding but can be complex to reverse engineer.

Disassembly Insights The game's executable consists mainly of Forth code, retaining its original structure without optimization. It contains many pointers and debugging symbols, allowing for significant reverse engineering. The code is slow due to frequent jumps between code blocks, which complicates execution speed.

Game Files Starflight consists of three main files, including game data and executable routines. The game structure includes various directories for graphics, maps, and data tables.

Usage Instructions To reverse engineer Starflight, place the original game files in specified folders and run a make command to generate output files, which will facilitate further exploration of the game's code and structure.

A user bought a smart sleep mask that monitors brainwaves and sends electrical impulses during sleep. The mask, made by a small Chinese company, has features like EEG monitoring and muscle stimulation. However, the app that controls it had connectivity issues, prompting the user to seek help from Claude, who reverse-engineered the mask's Bluetooth protocol and app.

Claude discovered hardcoded credentials in the app that allowed access to the company's MQTT broker, which is used for device communication. This enabled him to receive data not only from his mask but also from other devices, including brainwave data from multiple users' sleep masks.

The main concern is that because all devices share the same credentials, if one can read another's brainwaves, they can also send them electrical impulses. The user reached out to the company to inform them of this security flaw. The reverse engineering process was completed quickly and efficiently by Claude.

Recently, Anthropic and OpenAI introduced "fast mode" for their coding models, allowing users to interact with them at much higher speeds. However, there are key differences between the two:

1. Speed Comparison: OpenAI's fast mode can process over 1000 tokens per second, making it 15 times faster than its previous model, while Anthropic's fast mode processes up to 2.5 times faster than its earlier version.

2. Model Differences: Anthropic's fast mode uses the actual Opus 4.6 model, whereas OpenAI's fast mode uses a new, less capable model called GPT-5.3-Codex-Spark. This means OpenAI's fast mode is faster but less reliable.

3. Technical Approaches:

   • Anthropic employs low-batch-size inference, allowing for quicker responses by minimizing wait times.
   • OpenAI uses Cerebras chips, which are much larger than typical GPUs and enable faster in-memory processing, but their limitations necessitate a smaller, less capable model.

4. Strategic Timing: Anthropic's announcement seems like a strategic move to compete with OpenAI's faster inference, even though their method is less technically complex.

5. Future of Fast Inference: While both companies are exploring fast AI inference, it may not become a primary focus. The trade-off between speed and reliability is crucial, as faster models may result in more mistakes.

In conclusion, both companies have taken different paths to achieve faster AI inference, each with its own strengths and weaknesses.

The author discusses their experience playing the game Squeakross, which features picross puzzles. They find the puzzles frustrating due to their ambiguity, as some can have multiple valid solutions based on the given clues. This issue, known as an "Elementary Switch," occurs when clues do not provide enough information to distinguish between possible configurations.

In contrast, the author's own game, bicross, avoids this problem by ensuring all puzzles are uniquely solvable. Bicross uses a three-step process for level generation:

1. Generate a Level: A random boolean grid is created and filtered to ensure it meets a "fun-zone" density.
2. Constraint Propagation: The game calculates hints from the grid and checks for a unique solution using a method that tests all valid arrangements. It involves stacking permutations and pruning possibilities based on logical constraints.
3. Acceptance Criteria: The process repeats until a unique solution is found or no solution is possible. If ambiguity arises, the level is discarded, and a new one is generated.

This method can be CPU intensive, but the author notes it runs quickly enough for gameplay. They emphasize the importance of having provably solvable puzzles, particularly in a game that punishes players for mistakes.

The text explains how to create an interference pattern using a simple method involving a gap between two fingers and light from common sources like sunlight. This phenomenon is typically taught in high school physics through the double slit experiment, which demonstrates the wave properties of light.

The author clarifies that the interference pattern seen in the finger gap is not a result of single slit diffraction but rather "diffraction by a semi-infinite screen." This distinction is important because the characteristics of the patterns differ significantly between the two phenomena.

Diffraction occurs when waves bend around obstacles, and the author describes how to understand this concept using basic principles from physics. The text includes comparisons of interference patterns created by both single and double slits, explaining how the patterns and their spacing depend on the width of the slits.

Observations made with both fingers and a nail clipper show that the interference pattern does not change significantly with varying gap widths, which further supports the idea that the phenomenon is due to diffraction by a semi-infinite screen.

The conclusion emphasizes that coherent light is not necessary for interference patterns; even incoherent light can produce these patterns if the light source is small enough. Thus, anyone can observe interference patterns with simple setups using everyday materials.

The inner-platform effect refers to a common issue where software architects create systems that are overly customizable, resulting in them essentially replicating their development platform. This often leads to inefficiency and is considered an "anti-pattern".

Key Points:

• Definition: The inner-platform effect is the tendency to build complex systems that mimic the software development platform, instead of utilizing it effectively.
• Examples:
  • Plugins: In software like text editors and web browsers, developers sometimes create plugins that replicate operating system functions, which can be inefficient.
  • Database Design: Developers might store data in a simplified format that bypasses effective database management, leading to poor performance and complicated queries.
  • Web Desktops: Running a full desktop environment within a browser can create user confusion and inefficiency.
• Effects: Developers may end up duplicating functions that already exist in programming languages, making software slower and less reliable. However, in some cases, creating an inner platform can help with portability and managing different system privileges.
• Appropriate Use: Inner platforms can be beneficial when they allow applications to run across various environments without affecting external systems.

The inner-platform effect illustrates the risks of over-customization in software development, leading to unnecessary complexity and inefficiency.

Summary of Vibe Coding and Its Implications

Vibe coding involves generating complex AI-created code that is often not meant for human comprehension. This trend is affecting the tech industry, leading to job cuts as companies claim AI can replace human workers. Employees feel pressured to produce AI-generated code and worry about falling behind their peers. Many people are questioning the value of studying computer science due to AI's increasing capabilities.

While AI can be helpful, the writer cautions against fully embracing vibe coding. The results are often disappointing, as highlighted by developer Armin Ronacher, who experienced frustration with AI-generated tools that didn't work as expected. This phenomenon resembles gambling, where individuals may feel a false sense of achievement but ultimately face negative outcomes.

The article discusses the concept of "flow," a state of focused engagement, and how vibe coding can mimic this state without providing clear indicators of success, leading to poor productivity assessments. Many developers believe they are working faster with AI, but studies show they may actually be slower.

Predictions about AI's future capabilities, such as replacing software engineers, have often been overly optimistic. The author urges individuals not to neglect their skill development based on speculative claims about AI's potential.

Ultimately, human creativity and critical thinking remain essential. AI can generate code, but it lacks the ability to produce meaningful, organized software engineering. Relying too heavily on AI could lead to obsolescence in the workforce.

The article discusses the effectiveness of full-body MRIs in detecting cancer. While some people believe that these scans can help catch health issues early, medical experts are skeptical.

Key points include:

1. Cancer Detection Rates: Full-body MRIs often reveal "abnormal" findings, but only a small percentage (about 1.8%) are actually cancer. A study found that while 95% of patients had some abnormality, actual cancer detection was very low.

2. Cost and Accessibility: Full-body MRIs are expensive, ranging from hundreds to thousands of dollars, and are usually not covered by insurance, making them inaccessible for many.

3. Overdiagnosis Risks: There is a significant risk of overdiagnosis, where benign conditions are incorrectly identified as serious health issues. This can lead to unnecessary treatments and anxiety.

4. Context Matters: Experts advise that understanding the context of MRI results is crucial. A negative scan doesn’t ensure someone is disease-free, as some conditions might not be detectable at that time.

5. Future of Health Monitoring: Some specialists advocate for a more proactive approach to health monitoring, including regular check-ups and tests rather than one-time screenings.

Ultimately, while full-body MRIs can sometimes detect serious conditions, the medical community urges caution regarding their use, especially for asymptomatic individuals. Consulting with a healthcare professional is recommended for personalized advice.

Summary: The Three Year Myth

The author reflects on losing their job and realizes a pattern they call the "Three Year Myth." This myth involves being told to wait two to three years for promotions, raises, or changes within an organization. Employees trust this promise and continue to work hard, but often find themselves overlooked as others advance.

The author shares personal experiences of being ahead of the curve in suggesting beneficial changes but being ignored or rejected due to the timing or the power dynamics within the company. They emphasize that when leaders ask you to wait, it often protects their own interests at the cost of your growth.

The key takeaway is that waiting for recognition or advancement can be detrimental to your career. Promotions and rewards are dependent on who holds power, not on merit or timing. The author advises not to accept delays without context, as they might indicate you are seen more as a threat than an asset.

In conclusion, don't wait for what you deserve; seek recognition and growth now.

Astronomers have observed a massive star in the Andromeda Galaxy that collapsed into a black hole without going through a supernova explosion. This star, named M31-2014-DS1, is located 2.5 million light-years away and faded gradually instead of exploding. The outer layers of the star were slowly pushed away, while the core collapsed under gravity to form a black hole.

The researchers combined new telescope data with past observations to understand this unique event better. They found that the star brightened in infrared light starting in 2014 but dropped sharply in brightness by 2016, eventually becoming nearly invisible to standard telescopes. What remains of the star can still be detected in mid-infrared light.

This study suggests that not all massive stars explode dramatically; some may quietly collapse into black holes. The findings provide insights into how black holes form and indicate that convection processes in stars play a significant role in this transition. The outer layers of the star circulate and cool, creating a lasting glow from the debris, which will be observable for decades.

Overall, this discovery contributes to our understanding of the life cycles of massive stars and the formation of black holes in the universe.

Bobbie Chen has created a unique font that displays numbers in a style used by thirteenth-century Cistercian monks. This font features 9,999 ligatures, which are special combinations of characters that improve visual appearance and readability. Inspired by a previous post about generating Cistercian numerals, Chen decided to use font ligatures instead of images.

Ligatures are commonly used in digital fonts to prevent letter collisions and enhance text. This font allows users to replace standard numbers with Cistercian numerals, making it possible to find, copy, and use these numerals easily in any text.

Creating the font involved defining thousands of ligature rules to map sequences of numbers to their corresponding Cistercian glyphs. The design uses SVG paths from an existing numeral generator. Chen notes that the ordering of the Cistercian quadrants is different from modern numeral systems, which adds an interesting twist to how numbers are visualized.

Overall, the project showcases the creative possibilities of font design while raising awareness about potential misuse of such features. Chen encourages users to explore the font through a demo site. For more technical details, the code is available on GitHub.

The article discusses the differences in color representation for Pikachu images from two different Pokémon websites, highlighting how color models and profiles affect what we see.

Key Points:

1. Color Models: Screens use the RGB model (red, green, blue), while printers use CMYK (cyan, magenta, yellow, black). This affects how colors are displayed differently on screens and in print.

2. Image Details: The Pikachu image has a specific resolution and uses the CMYK color space. Each color in this model can have 256 possible values.

3. Color Profiles: These are used to ensure consistent color representation across different devices. The RGB standard is often sRGB, while CMYK has many profiles, such as U.S. Web Coated (SWOP) v2 and regional variations like Euroscale for Europe and Japan Color for Japan.

4. Unprofiled Images: If an image lacks an embedded color profile, software defaults to a specific profile, which can lead to color differences based on the user's location.

5. Color Comparison: The article compares two Pikachu images and finds they may use different color profiles, leading to the observed color differences. The exact "correct" color representation is unclear, suggesting that both might be valid regional variations.

In summary, color differences in Pokémon images arise from the color models and profiles used during creation and display, highlighting the complexities of digital color representation.

The 2025 Shkreli Awards, hosted by the Lown Institute, highlight the worst examples of greed and dysfunction in healthcare. Named after Martin Shkreli, the awards feature a list of nominees chosen by Lown Institute staff and input from readers. A panel of experts will select the winners.

One of the key issues highlighted this year is the dangerous practice of organ retrieval from patients who may still be alive or conscious. An investigation by the New York Times revealed that some patients are being pushed towards organ donation while still on life support and showing signs of awareness. This practice has increased due to pressure on organ procurement organizations to boost transplant numbers, leading to blurred lines between end-of-life care and organ harvesting.

Families have reported distressing experiences, such as their loved ones showing signs of consciousness during preparations for organ donation. This method, known as donation after circulatory death, has become more common despite previously being largely forbidden, now making up nearly a third of all organ donations.

The text explores the concept of "flood fill" in the context of AI automation and its limitations in the physical world. It begins by comparing the flood fill tool in image editing software to the potential reach of AI in various fields. While some believe AI will automate everything, the author argues against this notion, introducing the idea of a "magic circle," a concept derived from games that defines the boundaries of acceptable actions.

In human civilization, numerous "magic circles" exist, from simple games to complex systems like the economy and law. The magic circle for AI is defined as "symbols in, symbols out," meaning AI operates within strict parameters. Unlike other technologies, computation is flexible yet limited, as it struggles to interact with the messy realities of the physical world.

The author shares a personal project that illustrates the complexity of bridging the digital and physical realms, highlighting that while AI may assist in digital tasks, it cannot autonomously manage physical actions like mailing letters or affixing stamps.

The discussion emphasizes that automation often requires redesigning processes, as seen in sewing and olive harvesting, rather than simply replacing human effort. The text concludes that while AI may flood the digital space, it will face significant barriers in the physical world due to its inherent complexity.

Overall, the author suggests that individuals should consider how their work interacts with these magic circles and recognize the limitations of digital technologies in engaging with the physical world. They advocate for careful regulation of AI's role in physical tasks and reflect on the ongoing debate about the true impact of information technology on productivity.

Summary: WolfSSL Issues and Middlebox Compatibility

The author expresses frustration with various SSL/TLS libraries, particularly WolfSSL, OpenSSL, and GnuTLS. They note that OpenSSL has become slow, and while WolfSSL was adopted for some projects, it has significant issues with TLS 1.3 compatibility due to middleboxes—devices that can interfere with encrypted traffic.

The article highlights that TLS 1.3 includes a "Middlebox Compatibility Mode" to work around these issues, but WolfSSL requires this mode to be enabled at compile time, which leads to inconsistent functionality. The author discovered a bug when using WolfSSL with Elixir/Erlang, which prevented connections to WolfSSL servers if TLS 1.3 was used.

The author suggests that using LibreSSL may be a better alternative moving forward, as it avoids some of the issues present in other libraries. They conclude with a warning about the challenges faced when trying to implement faster TLS solutions and the importance of focusing on reliable libraries.

Summary: Inspecting the Source of Go Modules

Go has a strong system for ensuring the integrity of its packages through the Go Checksum Database. This database guarantees that all Go clients use the same source code for any given module version, even though Go modules can be fetched from different locations.

The Checksum Database works by storing a cryptographic hash of each module version the first time it is used. This hash is then provided to all Go clients, ensuring that if any changes are made to the code after its initial release (like force-pushing changes), the client will detect the mismatch and fail to fetch the module.

However, there's a risk when directly accessing code from code hosts like GitHub, which might not show the actual code version associated with a module. This can lead to issues, such as in a recent case where a fake module was published with malicious code.

To mitigate these risks, developers are encouraged to use commands that fetch the correct source code directly from the Checksum Database. Additionally, a new service called pkg.geomys.dev can be used to view the true source of Go modules and comes with browser extensions to enhance convenience.

Overall, while Go provides robust tools for ensuring package integrity, careful practices should be followed when reviewing code to avoid potential security issues.

The paper by Nick Bostrom discusses the timing of developing superintelligence (AGI) and its implications for humanity. Here are the key points simplified:

1. Superintelligence Development: Creating superintelligence is compared to risky surgery rather than a game of chance. It carries both potential benefits and serious risks.

2. Diverse Perspectives on AI: Some thinkers advocate for halting AI development due to fears of catastrophic risks, while others believe that even low risks might justify a complete stop. Bostrom argues that the risks of not developing superintelligence could be greater, as many currently suffer and die from preventable conditions.

3. Benefits of Superintelligence: Advanced AI could revolutionize medicine, potentially curing diseases and extending life significantly. It might also help humanity manage global threats more effectively.

4. Risk Assessment: The decision to develop superintelligence involves weighing the risks of AI-induced disasters against the ongoing risks of current technologies and diseases.

5. Optimal Timing: Bostrom suggests that the best strategy may be to quickly develop AGI capabilities and then pause before full deployment, but warns that poorly managed pauses could lead to negative outcomes.

6. Quality of Life Considerations: The analysis includes a focus on how life expectancy and quality of life could improve with superintelligence. Even with high risks, developing AGI might increase overall life expectancy.

7. Trade-offs: There’s a complex trade-off between the risks of launching AGI sooner versus the risks of delaying it to improve safety measures. Delaying could mean ongoing deaths from current issues.

8. Discounting Future Benefits: The paper discusses how valuing future benefits less (temporal discounting) can push decisions toward delaying AGI development, but this can vary based on the expected quality of life after AGI.

9. Diminishing Returns: There's an idea that the value of additional life years decreases as one lives longer, affecting the decision on when to launch AGI.

Overall, Bostrom emphasizes the need for careful consideration of risks and benefits when deciding on the timing of superintelligence development, suggesting that, under many scenarios, moving forward sooner may lead to better outcomes for humanity.
