Key accomplishments include:

• Developing a new agent inspired by Claude Code.
• Setting up a training environment using Docker containers for each task.
• Creating a synthetic data pipeline for generating and validating training data.
• Using a unique reward system that combines unit test results with evaluations from a language model.

Notable results:

• The untrained agent performed well, achieving 13.75% on the benchmark.
• The training setup worked efficiently across multiple servers.
• A mini-evaluation framework for assessing the performance of language model judges was established.
• Full training would require an estimated £30-50k for 1000 training epochs, which Dan could not afford at this time.

He also shared that the synthetic dataset includes a variety of tasks, from simple to very challenging. Dan encourages sharing knowledge in long-horizon RL, believing it has the potential to significantly impact lives. For more technical details, his work is open-sourced on GitHub.

Summary of Project Zero Update (July 29, 2025)

Google's Project Zero team has introduced a new trial policy called "Reporting Transparency" to improve how vulnerabilities are disclosed and addressed.

Key Points:

• Current Disclosure Model: Since 2021, Project Zero has used a "90+30" policy, which gives vendors 90 days to fix a vulnerability before it is disclosed publicly, followed by a 30-day period for users to adopt the patch.

• Identifying the Problem: There is a significant delay in getting fixes from vendors to end-users, known as the "patch gap." A newly identified "upstream patch gap" occurs when a fix exists but has not yet been integrated into the products that users rely on.

• New Trial Policy: Starting immediately, when a vulnerability is reported to a vendor, Project Zero will publicly announce:

  • The vendor or project that received the report.
  • The affected product.
  • The date the report was filed and when the disclosure deadline expires.

• Goals of the New Policy:

  • Increase transparency about reported vulnerabilities.
  • Encourage better communication between upstream vendors and downstream dependents.
  • Help researchers and the public track how long it takes for fixes to reach users.

• Security Considerations: The policy aims to raise awareness without providing technical details that could aid attackers. There is an acknowledgment that some vendors may find this approach challenging, but overall, it is believed that the benefits far outweigh the inconveniences.

• Future Outlook: This is a trial period, and Project Zero will monitor its effectiveness, hoping to create a safer environment where vulnerabilities are quickly addressed across all systems and devices.

The update emphasizes the importance of timely security updates to protect users and improve the overall security ecosystem.

In February 2025, researchers Alan Cao and Will Tan showcased their ability to exploit two outdated network devices during the Junkyard competition at DistrictCon. They highlighted that when manufacturers stop updating hardware, it leaves unpatched vulnerabilities that can be easily targeted by attackers.

The devices they exploited were a Netgear WGR614v9 router and a BitDefender Box V1. Both devices had not received updates for years, allowing the researchers to gain remote access. They developed multiple techniques to exploit the vulnerabilities in the Netgear router, focusing on issues with its UPnP service. By exploiting authentication bypasses and buffer overflows, they managed to execute commands remotely.

For the BitDefender Box, they discovered an unauthenticated firmware update mechanism. They extracted the firmware and found vulnerabilities that allowed them to gain persistent access to the device by exploiting outdated firmware.

The researchers emphasized the importance of being cautious with end-of-life (EOL) devices, as they can pose significant security risks. They recommended consumers check the support timelines of devices before purchasing and consider open-source alternatives. Additionally, EOL devices can be valuable for security research, providing opportunities to learn about vulnerabilities and improve skills in a less competitive environment than high-stakes competitions.

Summary: Do Variable Names Matter for AI Code Completion?

Truchet tiles are square tiles used in graphic design and information visualization. They feature patterns that are not symmetrical when rotated, allowing for diverse arrangements when tiled together. Each tile's orientation can represent different information based on its position.

These tiles were first introduced by Sébastien Truchet in 1704 and later gained popularity through Cyril Stanley Smith in 1987. There are several variations of Truchet tiles:

1. Contrasting Triangles: These tiles are divided diagonally into two triangles of different colors, with four possible orientations.

2. Quarter-Circles: These tiles have two quarter-circles connecting the midpoints of adjacent sides, with two possible orientations.

3. Diagonal Tiles: These consist of a white square with a black diagonal, also allowing for two orientations. This style can create labyrinth-like patterns.

Truchet tiles can also be used in abstract games and have interesting mathematical properties, such as their connection to percolation theory.

Many companies are now using AI voice agents to communicate with customers, but consumers are still making calls manually. To address this, I created Piper, an AI that makes phone calls on your behalf. You simply tell it what you need, like booking an appointment or checking an order, and it handles the conversation while you focus on other tasks.

Currently, Piper is a web app, with a Chrome extension coming soon. The technology involved was challenging, especially optimizing the response time to make conversations feel natural and ensuring the AI stays aware of the call context. So far, Piper has successfully completed around 50 calls, although it struggles with complex verifications and document requests.

I believe we're moving towards a future where AI will handle most routine phone calls, making interactions more efficient. You can listen to a voice demo on our website: pipervoice.com.

The film "Late Shift," directed by Swiss filmmaker Petra Volpe, highlights the struggles of overworked nurses in underfunded healthcare systems. It tells the story of Floria, a dedicated young nurse, as she faces overwhelming challenges during a single night shift at a hospital. The film aims to raise awareness about the nursing profession, which is predominantly female and often undervalued.

Volpe was inspired by real-life experiences of nurses and a novel by former care worker Madeline Calvelage. The movie portrays the emotional and complex nature of nursing, showcasing both the demanding work and the tender moments involved. German actress Leonie Benesch plays Floria and emphasizes the importance of portraying nurses as central figures, rather than sidelining them behind doctors.

"Late Shift" has sparked discussions about healthcare reform and has been well-received in German-speaking Europe, even outperforming major films at the box office. The film has resonated with real nurses, who have found its depiction of their work to be accurate and relatable. Volpe hopes the film will encourage better understanding and support for nurses, as well as inspire audiences to appreciate their vital role in healthcare.

The film will be released in the UK and Ireland on August 1.

In July 2025, the conversation around AI design is critiqued, referencing a 1992 talk by researcher Mark Weiser, who opposed the idea of AI as a "copilot." Instead, he argued for designing technology that enhances human awareness—what he called an "invisible computer."

Weiser's concept can be illustrated through modern Head-Up Displays (HUDs) in planes, which provide critical flight information without requiring verbal interaction. This is different from a copilot, which actively communicates instructions.

In software design, examples of HUDs include spellcheck, which visually indicates errors without an assistant interface, and custom debugging tools that help users understand program behavior better.

The text emphasizes that while HUDs are not always superior to copilots, they can enhance human capabilities. Routine tasks may be delegated to virtual assistants, but for complex situations, better tools that extend human understanding are preferable.

The author encourages exploring non-copilot designs in AI to improve user experience and understanding.

The author is interested in Mastodon but is not currently using it. They noticed that new regulations (OSA) could complicate self-hosting Mastodon due to age verification requirements. However, these rules only apply to services with at least 3 million monthly users, meaning small self-hosters might be safe. Yet, if they connect with larger instances, they might still face risks. The author questions whether UK-based Mastodon hosts are worried about these regulations and if they are considering shutting down to avoid liability, raising concerns about the future of Mastodon hosting in the UK.

Next month, we will implement new weekly rate limits for Claude subscribers, which will affect less than 5% of users based on their current usage. This change is due to issues like account sharing and excessive usage that are straining our system.

Key changes starting August 28:

• Weekly usage limits will be added alongside the existing 5-hour limits that reset every 5 hours.
• There will also be a new 7-day limit for Claude Opus 4.

Most users shouldn't notice much difference, as these limits support regular daily use. For Max 5x users, weekly limits will allow for 140-280 hours of Sonnet 4 and 15-35 hours of Opus 4. However, heavy users may reach their limits more quickly.

You can manage or cancel your subscription anytime. We are committed to improving service reliability and are working on fixing any ongoing performance issues.

Summary of The Ultimate Guide to MCP Auth: Identity, Consent, and Agent Security

This guide explains the challenges of using Model Context Protocol (MCP) for building AI systems. MCP allows AI agents to make decisions based on context, but it also introduces security and identity issues. Here are the key points:

1. Understanding MCP: MCP is more than just an API; it helps agents understand their environment and make decisions. However, this also expands the risk of misuse.

2. Authentication and Authorization Layers: There are five important layers to consider:

   • Agent Identity: Each agent needs a unique identity for tracking purposes.
   • Delegator Authentication: Users must confirm their identity and consent for agents to act on their behalf.
   • Consent: Users specify what actions agents can take and under what conditions.
   • Access to MCP Server: Agents must authenticate to access tools and context.
   • Access to External Services: Tools that agents use may require further authentication.

3. Complexity from Context: The context provided to agents can influence their behavior, creating risks like manipulation and accidental data leaks. This makes access control more complex.

4. Current Limitations: MCP is still evolving, leading to inconsistent implementations and documentation. Many existing systems lack adequate support and policy enforcement.

5. Using Middleware: Implementing middleware can help manage authentication, consent, and logging actions, enhancing security and oversight.

6. Consent Management: Consent in MCP should be detailed and specific, not just a simple approval during OAuth. It must be revocable and auditable.

7. Recommended Practices:

   • Assign unique identities to all agents.
   • Use consent as a primary control mechanism.
   • Implement middleware for better security and policy enforcement.
   • Focus on fine-grained permissions rather than relying on static tokens.

In conclusion, while MCP offers powerful capabilities for intelligent systems, it requires careful attention to identity and consent to ensure security and reliability.

The article discusses a unique microbe found in Yellowstone National Park that can simultaneously breathe oxygen and sulfur, a process called dual respiration. Typically, organisms either rely on oxygen (aerobic respiration) or use other elements like sulfur (anaerobic respiration) to extract energy. This dual capability challenges previous assumptions about microbial metabolism and suggests that some microbes might have evolved to manage both processes, which could have implications for understanding how life adapted during Earth's transition to an oxygen-rich environment known as the Great Oxidation Event.

Researchers, led by microbiologist Eric Boyd, isolated a strain of this microbe called Hydrogenobacter RSW1. They found that when both oxygen and sulfur are present, RSW1 can grow and generate energy from both, unlike most anaerobic organisms that would be harmed by oxygen. This discovery could indicate that many microbes might have similar abilities, helping them thrive in environments where oxygen levels fluctuate. The findings might also provide insights into the evolutionary adaptations of life as it transitioned to new atmospheric conditions billions of years ago.

The article discusses the use of useCallback and useMemo in React, pointing out that they are often used unnecessarily. The main reasons to use these hooks are for performance optimization and to maintain stable references to functions and values to avoid unnecessary re-renders. However, the author argues that there are cases where memoization is pointless, especially when the memoized values are passed to non-memoized components, as this does not provide any performance benefits.

Key points include:

1. Performance Optimization: Memoization is intended to reduce the frequency of slow operations, such as re-rendering components. However, if a component isn't memoized, the memoization of props is irrelevant.

2. Referential Stability: The primary goal of using useCallback and useMemo is to ensure that references remain stable across renders. This is crucial for performance when using memoized components.

3. Common Pitfalls:

   • Memoizing values that are not passed to memoized components does not yield performance gains.
   • Using props as dependencies in effects can lead to unnecessary re-renders and break memoization.

4. Real-World Example: The author shares an example from their work that illustrates how improper memoization can lead to inefficiencies and bugs.

5. Alternative Patterns: The author suggests using a ref to hold values that need to be accessed in effects without being included as dependencies, thus avoiding the complexity and overhead of unnecessary memoization.

In summary, the article emphasizes being cautious with memoization in React and suggests alternative strategies to manage performance without overcomplicating the code.

Summary:

The research paper "SRAM Has No Chill" discusses a new attack method called Volt Boot, which targets on-chip SRAM (Static Random Access Memory) to retrieve sensitive data. Unlike traditional cold boot attacks that require extremely low temperatures to exploit data retention in DRAM, Volt Boot takes advantage of the power separation in modern system-on-chip (SoC) designs.

Key Points:

1. Background: Cold boot attacks exploit the temperature-dependent data retention of DRAM. However, SRAM loses data quickly when powered off, making it seem secure against these attacks.

2. Volt Boot Attack: This new attack method enables data retention in SRAM across power cycles by manipulating the power supply to the memory. By maintaining voltage to certain memory domains, data can be preserved even when the main power is disconnected.

3. Execution: The researchers successfully demonstrated this attack on various ARM Cortex-A processors, retrieving data from caches, registers, and internal RAMs with 100% accuracy.

4. Vulnerability: Volt Boot reveals that current on-chip security measures are insufficient, as it allows attackers to access sensitive information stored in plain text in SRAM, undermining the security of embedded systems.

5. Countermeasures: Potential defenses against Volt Boot include purging memory during the power-down sequence, resetting SRAM at startup, using hardware-based security features like ARM TrustZone, and enforcing authenticated boot processes.

6. Conclusion: This research shows that while on-chip memory designs were thought to be secure against cold boot attacks, the separation of power domains can be exploited to leak sensitive data. The findings highlight the need for better security measures in modern computing devices.

Summary of "Six Principles for Production AI Agents"

This article by Arseni Kravchenko outlines six key principles for developing effective AI agents. Here’s a simplified overview of each principle:

1. Invest in Your System Prompt: Clear and detailed prompts are essential for AI models to perform well. Avoid ambiguous instructions and follow best practices provided by LLM (Large Language Model) providers.

2. Split the Context: Manage context effectively to prevent models from hallucinating or losing focus. Start with minimal necessary information and allow access to additional context as needed.

3. Design Tools Carefully: Create straightforward and well-defined tools for AI agents. Limit the number of tools to avoid confusion and ensure they have clear functionalities, similar to a well-designed API.

4. Design a Feedback Loop: Implement a two-phase approach where the AI generates actions (actor) and evaluates them (critic). This ensures that outputs meet predefined standards, enhancing reliability.

5. LLM-Driven Error Analysis: Use error analysis to improve AI agents. Analyze logs of agent performance with LLMs to identify blind spots and enhance context and tool design.

6. Frustrating Behavior Signals System Issues: Frustrating behaviors in agents often stem from system errors rather than flaws in the LLM itself. Always check for missing tools or unclear prompts before blaming the model.

Conclusion: Building reliable AI agents involves good system design and software engineering. Focus on clear instructions, effective context management, robust tools, and continuous error analysis to create agents that can recover from failures and improve over time.

Telescopes on Earth and in space are observing Comet 3I/ATLAS, the third interstellar object seen in our solar system, after Comet 2I/Borisov and the non-comet 1I/‘Oumuamua. This comet is moving faster than the previous interstellar objects and is on a path close to the solar system's plane.

Recent observations, including images from the Vera C. Rubin Observatory, confirm that 3I/ATLAS has a faint, dusty coma and hints of a tail pointing towards the Sun, which is unusual for comets. The estimated size of the comet's nucleus is between 0.5 and 11.4 kilometers (0.3 to 7 miles).

Its origin is still unclear, but some researchers suggest it might be very old, possibly around 7 billion years, having come from the Milky Way's thick disk. The comet will pass near Jupiter, Mars, and Venus, but it will be faint in December and hidden from view when it gets closest to the Sun.

Despite this, some spacecraft, like the Jupiter Icy Moons Explorer (JUICE) and Psyche, may be able to observe the comet during its closest approach. Continuous observation is important to capture any unusual activities, such as fragmentation, as the comet travels through the solar system.

A former worker at the Gaza Humanitarian Foundation (GHF), Anthony Aguilar, has resigned, citing witnessing severe violence by the Israeli Defense Forces against Palestinian civilians. He described the situation as brutal, with unnecessary force used against unarmed and starving people. Aguilar's experiences highlight the ongoing conflict in Gaza and the humanitarian crisis affecting the population.

A new HIV prevention drug called Yeztugo has been approved, marking a significant breakthrough in the fight against HIV. This drug is a capsid inhibitor that offers 100% protection against HIV with just two injections per year. It aims to help millions, especially in low-income countries, as Gilead Sciences and the Global Fund are providing it royalty-free to ensure affordability.

Yeztugo received FDA approval and is expected to be accessible in various countries, with plans to reach up to two million people over three years. This effort includes partnerships for the production of generic versions in resource-limited areas. Experts believe this long-acting medication could significantly increase adherence to HIV prevention and reduce stigma associated with more frequent dosing methods.

Gilead's approach prioritizes public health over profit, emphasizing the need for global access to this life-saving drug. The Global Fund is working to establish the necessary infrastructure to distribute Yeztugo effectively in the regions that need it most. This development represents a hopeful turning point in the ongoing battle against HIV/AIDS.

The "iron law of oligarchy" is a political theory developed by sociologist Robert Michels in his 1911 book, Political Parties. It suggests that all democratic organizations inevitably become dominated by a small elite group, or oligarchy, due to the complexities of managing large organizations. Michels argues that as organizations grow, they require a structured hierarchy, leading to power being concentrated in the hands of a few leaders.

Key points of the theory include:

1. Inevitability of Oligarchy: Regardless of an organization’s initial democratic ideals, it will eventually develop oligarchic tendencies. This occurs because large groups need organization and leadership to function effectively.

2. Delegation and Bureaucracy: As organizations expand, decision-making becomes too complex for all members to participate directly. This leads to the delegation of power to a leadership class, which can become disconnected from ordinary members.

3. Control and Information: Leaders often control important information and can manipulate processes to maintain their power, making accountability difficult.

4. Historical Examples: Michels observed this dynamic in various political parties and unions, noting that even socialist groups, despite their democratic goals, fell into oligarchic patterns.

5. Counterexamples: Some organizations, like the International Typographical Union, have demonstrated ways to resist oligarchy through strong local autonomy and active member participation.

Overall, Michels' theory suggests that true democracy is challenging to achieve in large organizations, as structures inherently favor a leadership class over widespread participation.

Félix Nadar, born Gaspard-Félix Tournachon in 1820, was a pioneering photographer and a key figure in 19th-century Parisian culture. He is celebrated as the world's first celebrity photographer, known for his insightful portraits of famous artists and writers. Nadar's studio hosted the first Impressionist exhibition and he took the first aerial photograph.

With a vibrant personality and a flair for self-promotion, Nadar made a name for himself among Paris's elite. He began his career in journalism and caricature, building connections with influential figures like Charles Baudelaire and Alexandre Dumas. His photography style focused on capturing the essence of his subjects, using simple backgrounds and natural light to highlight their personalities.

Nadar also pursued ballooning and was involved in early aviation, famously taking an aerial photo of Paris in 1858. He founded the Society for the Encouragement of Aerial Locomotion, aiming to develop flying machines.

Though his son Paul Nadar continued the family legacy in photography, he did not achieve the same acclaim as his father. Félix Nadar remains a legendary figure, admired for his contributions to photography and culture in France. An exhibition of his work was held at the Bibliothèque Nationale in Paris until February 2019.

The text discusses a new font called 433, which replaces visible text with dots and is being used in the latest version of an app called Ensō, particularly in a feature called Coffeeshop Mode. The main reasons for using this font are its simplicity and the author's curiosity.

The author gained nearly 400 testers for Ensō after a previous note went viral, leading to a diverse group of users. This provided an opportunity to test various text rendering methods and eventually led to the decision to create a font that displays a dot for all non-whitespace characters.

The font's name, 433, is inspired by the musical piece 4′33″. The author explains how fonts work, defining them as collections of glyphs that represent characters and are mapped to code points. The goal was to create a compact font that covers a wide range of characters while remaining small in file size.

Through a step-by-step process, the author outlines how the font was created using FontForge, focusing on efficiency by referencing a single dot glyph for multiple code points to reduce size. The final font file, generated in WOFF2 format, was significantly smaller than its TTF counterpart.

The author reflects on the challenges faced, the skills required, and the satisfaction of overcoming these obstacles in font creation. They emphasize the importance of recognizing achievements and learning from experiences. The post concludes with gratitude to a team member who assisted in the effort.

Summary: The Ultimate Meeting Culture

An effective meeting culture allows employees to decline meetings when necessary, helping to reduce the overwhelming number of unproductive meetings that waste time and money. Many meetings lack clear purpose, leading to frustration and confusion among attendees.

Key Points:

• Purpose of Meetings: Meetings should focus on brainstorming solutions and making group decisions, rather than just sharing information (which is better suited for written communication).
• Meeting Structure: Hosts should provide an agenda with time estimates and expected outcomes, take minutes, and keep discussions on track. Meetings should end on time to respect everyone’s schedules.
• Expectations for Attendees: Participants should only attend meetings relevant to them, come prepared, and actively engage in discussions. If declining a meeting, they should understand they forfeit their chance to influence the outcome.
• Handling FOMO (Fear of Missing Out): If you’re not actively participating, it’s better to read the minutes afterward rather than sit through the entire meeting.

By creating a clear and disciplined meeting culture, organizations can improve productivity and reduce unnecessary attendance, allowing everyone to focus on more meaningful work.

Summary of "The Geological Sublime" by Lewis Hyde

In this essay, Lewis Hyde reflects on the concepts of deep time, climate change, and the fragility of butterfly populations. He begins with a personal experience of an earthquake that reminds him of the immense geological forces at play and how they connect to Earth's history over millions of years.

Hyde discusses the insights of geologists like Charles Lyell and Charles Darwin, who introduced the idea of deep time, emphasizing that the Earth has been shaped by slow, gradual processes over vast periods. He contrasts this geological time with the rapid changes in climate and species extinction occurring today. For instance, he notes that butterfly populations in New England have dramatically decreased, with some species disappearing due to changing environmental conditions.

The essay explores the challenge of comprehending deep time when faced with urgent climate issues. Hyde argues for the necessity of understanding the long-term context of Earth's history to grasp the significance of current environmental crises. He also reflects on the idea of "temporal proportion," acknowledging the difficulty of reconciling human timelines with the geological timescale.

Hyde incorporates personal anecdotes about butterfly watching, highlighting the beauty and complexity of nature while also acknowledging the threats that climate change poses. He concludes by emphasizing the importance of recognizing our place within the vast history of the Earth and the need for a deeper understanding of the interconnectedness of life and the environment.

A recent study explored how different large language models (LLMs) identify public figures in images. The researcher tested models like ChatGPT, Claude, and Google’s Gemini with images of notable individuals, including Barack Obama, to see how accurately they could recognize them.

Key findings include:

• ChatGPT and Claude often refused to identify public figures, likely due to strict privacy and safety guidelines.
• In contrast, Gemini successfully identified public figures without hesitation, suggesting it has different training and reinforcement learning methods.
• Other models like Llama, Mistral, and Qwen also identified Obama accurately.
• When tested with images of non-notable individuals (like the researcher), models correctly stated that no notable person was present.
• In tests with multiple public figures, Gemini and Qwen provided accurate identifications, while others struggled with name order or hallucinated incorrect names.

The study concluded that Gemini outperformed the others in identifying public figures, likely due to its access to extensive training data. The researcher expressed concerns about the ethical implications of LLMs identifying public figures, especially if this capability extends to non-public figures in the future.

Summary of Claude's Findings on Contradictions in Thinking

Claude examined two Obsidian vaults for contradictions in the author's thoughts and identified several key tensions that reflect the author's intellectual journey:

1. Power Paradox: The author recognizes that power can corrupt but also believes seeking influence isn't inherently bad. This raises questions about maintaining spiritual detachment while desiring influence.

2. Digital Engagement Dilemma: The author wants to engage thoughtfully with digital tools for meaningful purposes, yet criticizes the reactive culture they foster.

3. Action vs. Acceptance: The author's writings show a tension between accepting limitations and actively seeking to create change, reflecting a struggle to balance Eastern philosophies of acceptance with Western ideals of personal agency.

4. Knowledge Paradox: The author questions the value of consuming information without emotional engagement while advocating for extensive intellectual output.

5. Individual vs. Collective Focus: There’s a conflict between the desire for personal legacy and the belief in contributing to others’ fulfillment.

In the second vault, additional tensions include:

• Autonomy vs. Systems Integration: The author values autonomy but also engages heavily with institutional processes, showing a desire to reform them from within.

• Risk-Taking vs. Risk-Averse Engagement: There’s a discrepancy between advocating for risk-taking and navigating conventional academic systems.

• Problem-Solver vs. Opportunity-Creator: The author promotes opportunity creation but often frames proposals as solutions to existing problems.

• Individual Genius vs. Collaborative Systems: The author admires individual visionaries while also advocating for collaborative approaches, indicating a tension between individualism and systemic improvement.

• Academic vs. Entrepreneurial Identity: The author feels trapped between academic rigor and entrepreneurial drive.

Overall, Claude notes that these contradictions are not flaws but rather signs of the author’s evolving thought process. The author is grappling with complex philosophical questions, and the tensions have become more sophisticated over time, indicating an ongoing intellectual development.

A user tested Trae, a version of VSCode developed by ByteDance, and found several major issues:

1. High Resource Usage: Trae uses significantly more RAM (5.7 GB) and processes (33) compared to standard VSCode.

2. Ineffective Telemetry Settings: Even after disabling telemetry, Trae continued to send data to ByteDance's servers, and the data collection actually increased.

3. Data Being Sent: Trae collects detailed information, including hardware specs, user IDs, OS version, and usage data, even with telemetry turned off.

4. Community Censorship: The user faced censorship on Discord when trying to discuss these issues, as posts about privacy were deleted, and their account was muted.

The user warns that these problems raise concerns about performance, privacy, and open discussion. A detailed analysis with evidence is available in the linked post.

Debian, a well-known Linux distribution, is preparing to avoid the Year 2038 problem (also called the Unix Epochalypse) by switching to 64-bit time for most of its systems in the upcoming Debian 13 "Trixie" release. This change is necessary because, on January 19, 2038, the way time is measured on many systems (using a 32-bit integer) will overflow, potentially causing errors.

To address this, Debian developers will implement a 64-bit time format, even for 32-bit hardware, although the oldest hardware will still use the current system for compatibility. This transition affects thousands of software packages, requiring significant work to ensure compatibility across the platform.

While systems using 64-bit hardware are already safe, many older and budget-friendly devices still rely on 32-bit processors. The developers are confident that the transition will be completed successfully to prevent problems as the 2038 deadline approaches.

Anker has paused sales of its 3D printers, the M5 and M5C, indefinitely. Initially, Anker planned to separate its 3D printing business into a new sub-brand called EufyMake, which would still support existing products. However, EufyMake has stopped selling 3D printers and is no longer providing key parts needed for maintenance. Customers are struggling to find essential components like the hotend for the M5C, leading to frustrations among users. Although Anker hasn't ruled out future 3D printer models, there are currently no plans to resume sales of the existing models. Other companies in the 3D printing market have also faced challenges. For those seeking reliable 3D printers, alternatives like the Bambu P1S and P1P, and the Elegoo Centauri Carbon are recommended.

The text discusses a significant shift in how power operates in society, termed "leverage arbitrage divergence." This refers to the widening gap between actors who can quickly change the world (like tech companies) and those who respond slowly (like educational institutions and governments).

There are three types of leverage:

1. Labor leverage - Coordination among people (e.g., committees).
2. Capital leverage - Resource deployment (e.g., investments).
3. Code leverage - Automation and technology (e.g., algorithms).

Higher-order leverage (like code) allows certain actors to extract value rapidly, leading to challenges for those with lower-order leverage. For example, tech companies can reshape society faster than democratic institutions can adapt, resulting in a decline of essential shared resources like trust and social cohesion.

This disconnect causes various societal issues, such as feelings of powerlessness among individuals despite access to technology, and government regulations that lag behind technological advancements.

To address these challenges, the author suggests developing "leverage literacy" to help people understand and use their power effectively. Additionally, there's a need to redesign how success is measured and resources allocated to ensure long-term benefits for society.

In summary, the future depends on our ability to coordinate across different types of leverage rather than optimizing within them, which could either lead to societal progress or dysfunction. The choice is ours to make.

In 2023, connecting two devices directly can be challenging. A solution called "Dumb pipe" helps by bypassing network barriers and using temporary identifiers for the devices. It also maintains the connection even when network conditions change. What you choose to do with this connection is entirely up to you.

Summary:

Google has updated Android's Linux Terminal app, allowing it to run graphical Linux applications, including games like Doom, in its latest Canary build. This new feature adds a "Display" button that opens a graphical environment, enabling users to run desktop apps not available on Android.

The Terminal app, which runs a Debian virtual machine, previously only supported command line programs. Now, users can enable hardware acceleration for better performance by creating a specific file in the app's directory.

This update is significant as it expands the capabilities of Android by allowing access to various Linux programs and potentially PC games in the future. While currently available in the Canary build, it's unclear when this feature will reach the Beta or Stable versions, but it may be included in the upcoming Android 16 release in December 2025.

In Flanders, a new system of "intelligent traffic lights" has been introduced over the past two years, allowing drivers and cyclists to turn traffic lights green faster using a smartphone app. So far, 230 out of 250 planned intersections have been equipped with this technology. About 200,000 users currently have apps that can control these lights, leading to smoother traffic flow.

However, popular navigation apps like Google Maps and Waze are not participating, limiting the system's reach. The Roads Agency is trying to get these major apps involved to increase user adoption. Meanwhile, emergency services have benefited from the system, allowing ambulances and fire trucks to get green lights and respond more quickly to emergencies.

Traditional computer architectures face problems because they need to constantly move data between memory and processing units, which slows down performance and wastes energy, especially as technology advances. Photonic in-memory computing offers a solution by using light for faster data transfer, reducing delays and energy usage.

This research introduces a new type of photonic static random access memory (pSRAM) called X-pSRAM, which allows for rapid data storage and ultra-fast Boolean XOR calculations. It uses special components like microring resonators and photodiodes to achieve operations at speeds of at least 10 GHz entirely using light.

Additionally, it supports multiple calculations simultaneously through a method called wavelength-division multiplexing (WDM). The X-pSRAM has been tested and shown to use only 13.2 femtojoules of energy per bit for XOR operations, marking a significant step forward in optical computing technology. This advancement could benefit fields like cryptography, hyperdimensional computing, and neural networks.

Summary: Fixing Blog Performance with a New Jekyll Plugin

The author created a new Jekyll plugin called jekyll-skyhook to improve their blog's performance after discovering that Google was not indexing their pages. Key issues included:

1. Content Issues: The author acknowledged that their blog content needed improvement and planned to promote it better for backlinks.

2. Performance Problems: Using tools like Google PageSpeed Insights, they found a low score of 43 out of 100 due to:

   • Google Fonts: The author switched to self-hosting fonts instead of using the Google Fonts CDN.
   • YouTube Embeds: They replaced standard YouTube embeds with a more efficient library, lite-youtube.
   • Image Optimization: Initially, images were not optimized for performance. The author recognized the need for responsive images and lazy loading.

To address these issues, the author developed jekyll-skyhook, which includes features like:

• Automatic image resizing and format conversion (e.g., WebP, AVIF).
• Responsive image support with srcset generation.
• Cache-busting URLs for assets.
• Automatic CSS URL rewriting.

The blog structure was organized to use modern tools like npm for processing assets, with a clear build and deployment process.

Summary of AV-Racer Devlog (1): Getting a Functional Car Model

The article discusses the early stages of developing a car game, focusing on how to simulate a car's movement. The author initially lacked knowledge about car physics but collaborated with a friend to gather useful information. They set up a basic project using SDL2 for graphics and later switched to OpenGL.

The project began with a simple car model that could move in a 2D space, responding to keyboard inputs for acceleration. However, their attempts at realistic car physics were unsuccessful, leading them to adopt a simpler, arcade-like approach.

To simulate the car's movement, they simplified the model to treat the car as a single object rather than multiple tires. They developed an acceleration system that adjusts the car's velocity based on gas input, ensuring that the acceleration direction aligns with the car's orientation. The article hints at further refinements and adjustments to improve the game's mechanics.

John Graham-Cumming discusses his project of connecting his vintage KIM-1 computer from 1976 to his Mac. He believes that old hardware should be actively used rather than left unused. The KIM-1 can be connected to a terminal, like the ASR Teletype, through a current loop interface, which is different from common voltage-based serial connections.

He found a kit to create an adapter between RS-232 and the KIM-1's current loop but encountered an issue with the circuit that required a modification. After building the kit, he successfully adjusted it to allow communication between the KIM-1 and his Mac. The KIM-1 can communicate at 1200 baud using ASCII, and he uses a terminal program called minicom. Additionally, he plans to emulate a punched tape format for easier program uploads to the KIM-1.

The text discusses the emerging role of AI companions and their implications on society, particularly focusing on their use, effectiveness, and potential risks. Key points include:

1. Popularity among Teens: About 72% of teens have tried AI companions, with 52% using them regularly. Many find interactions with AI companions satisfying, sometimes even more so than with real friends.

2. Persuasion and Personalization: Research indicates that larger AI models are more persuasive. While personalization can enhance engagement, its effects are currently small compared to the influence of model size and post-training adjustments. There are concerns that as personalization improves, it may lead to increased manipulation and deception.

3. Risks and Concerns: AI companions raise significant risks, especially for young users. Issues include the potential for fostering unhealthy social behaviors and the challenge of ensuring AI systems respect user privacy and preferences.

4. Goonpocalypse Fear: There is concern about a future dominated by hypersexualized AI interactions (termed "goonpocalypse"), but evidence suggests that current usage patterns are more benign.

Summary: How to Create Time-Consuming Websites

1. Use Many Dependencies: Install lots of tools and libraries (npm packages) without understanding them. When they break, you'll spend time replacing them with new ones that will also break.

2. Choose a Framework Early: Pick a framework before you truly need it. When updates occur, you'll need to understand the changes, which will take more of your time.

3. Require Complicated Processes: Implement steps that make it necessary to compile or build your site before you can view it in a browser. This adds extra time and effort since you’ll be working on the build process rather than the actual website.

If you have more tips on making websites that consume a lot of your time and energy, feel free to share!

The National Science Foundation (NSF) plans to end operations of the RV Nathaniel B. Palmer, the only U.S. research ship that can navigate the extreme conditions of Antarctica and the Southern Ocean. This decision has raised concerns among polar scientists, leading over 170 researchers to urge the NSF and Congress to reconsider. The Palmer has been crucial for scientific research in Antarctica since 1992, particularly for studying the Thwaites Glacier.

Although the U.S. intends to build a new research icebreaker, it won't be ready for at least a decade, and the NSF recently cut funding for the planning of a successor ship. The NSF's budget request for 2026 indicated the termination of the Palmer's lease to focus on Antarctic stations instead.

The RV Sikuliaq, another icebreaker, is expected to take over some of the Palmer's responsibilities, but scientists say it is less capable for Antarctic research. The NSF has not clearly communicated its plans, leaving researchers uncertain about upcoming expeditions. Some hope Congress will intervene to maintain access to the Palmer, as it remains vital for field research in the region.
