Archaeologists from the University of Houston have discovered the tomb of Te K’ab Chaak, the first king of the ancient Maya city Caracol in Belize. This is the first identifiable ruler's tomb found in over 40 years of research at the site, which was a significant political center from 560 to 680 AD.

Te K’ab Chaak was buried with valuable items, including pottery, jade jewelry, and a jade mask. His tomb is part of a broader investigation into the connections between Maya and central Mexican cultures. The findings suggest that early Maya rulers, like Te K’ab Chaak, had diplomatic ties with the city of Teotihuacan in Mexico, indicating a complex relationship between the two regions.

The excavation team, led by married archaeologists Arlen and Diane Chase, has been studying Caracol for over 40 years. Their work has revealed that Caracol was a well-planned city with advanced infrastructure and a diverse population, challenging previous notions of a simple social hierarchy among the Maya.

The Chases will share more about these discoveries at an upcoming conference in August 2025.

Summary of Xbox Hacks: The A20

This year marks the 20th anniversary of the original Xbox, which was known for its vulnerabilities. One significant issue was related to the A20 address line in its Intel Pentium III processor.

Historically, early CPUs like the Intel 8088 had limitations in memory addressing due to their design, which could lead to a "wraparound" effect when memory was accessed beyond their limits. IBM addressed this with the A20 gate, allowing systems to switch between old and new memory behaviors.

The Xbox utilized this A20 gate, which meant that by grounding the A20 line, the system could boot into a flash memory with potentially unauthorized software instead of the secure ROM. This posed a security risk for Microsoft, as it allowed for unauthorized access to system features.

The information about this vulnerability was shared by Michael Steil, a key figure in the Xbox Linux Project. As the anniversary of the Xbox approaches, there will be more discussions about its history and vulnerabilities.

MIT researchers have developed a new bionic knee prosthesis that significantly improves mobility for individuals with above-the-knee amputations. This innovative prosthesis integrates directly with the user’s muscle and bone tissue, enhancing stability and control compared to traditional prosthetics.

In a small clinical study, participants using this new system reported they could walk faster, climb stairs, and avoid obstacles more easily. The prosthesis allows users to control its movements using signals from their residual muscles, making it feel more like a natural part of their body.

The new approach, called the agonist-antagonist myoneuronal interface (AMI), reconnects muscle pairs during surgery to maintain their natural communication, improving the user’s ability to control the prosthesis. The bionic knee is also equipped with a titanium rod that integrates into the femur, providing better mechanical support and sensory feedback.

Participants using the combined AMI and the new system, known as the osseointegrated mechanoneural prosthesis (OMP), felt a stronger sense of ownership and control over their prosthetic limb compared to those with traditional or less integrated systems. The researchers aim to conduct larger trials for FDA approval, which may take around five years.

• Other differences: Walking slowly, taking wider steps, and spending more time with one foot on the ground.

These gait differences often accompany other motor challenges, like issues with balance and coordination, due to differences in brain areas responsible for movement control.

These gait characteristics can last throughout a person’s life and may become more noticeable with age. Not everyone with autism will require support for their gait, especially if it doesn't hinder daily activities. However, if gait issues lead to falls or affect participation in activities, support may be beneficial.

Programs that promote movement in everyday settings, like schools, can help autistic children develop their motor skills. Community-based activities, such as sports or dance, can also improve their movement abilities.

Research continues to explore individual variations in gait and how best to support different movement styles in autistic individuals. Overall, physical activity is shown to enhance social skills and behavior regulation in autistic preschoolers, encouraging a shift towards community-based support for these children.

The article "What’s Happening to Reading?" by Joshua Rothman discusses how artificial intelligence (A.I.) is changing the way we read and interact with text.

Key Points:

1. Shift in Reading Habits: Traditionally, reading was a straightforward, solitary activity. However, with the rise of digital technology, many people now consume information in different forms, like social media and audio content, which has altered their reading experiences.

2. Decline in Traditional Reading: Recent statistics show a decline in reading among adults and teenagers. For example, the percentage of adults reading at least one book a year dropped from 55% to 48%. Among teenagers, daily reading for fun fell from 27% to 14%.

3. Impact of A.I.: A.I. technologies are changing our reading landscape. Writers are now considering that their work may be consumed by A.I. as well as humans, leading to new ways of thinking about writing and reading. A.I. can summarize texts, making it easier for users to engage with content.

4. A New Reading Culture: The article suggests that in the future, reading may involve more interaction with A.I., leading to a culture where texts are seen as flexible and subject to change, rather than fixed. This could challenge the value of original texts and the concept of being "well-read."

5. Concerns and Opportunities: While some fear that A.I. might diminish the quality of reading experiences, others see potential in using A.I. to enhance understanding and access to a wider range of texts. The relationship between readers and texts may evolve, emphasizing brevity and adaptation over traditional, in-depth reading.

Overall, Rothman argues that as A.I. continues to influence reading practices, it may redefine our relationship with literature and knowledge.

Summary of LLM Daydreaming Proposal

This proposal discusses the limitations of current AI systems, particularly large language models (LLMs), in generating new insights and ideas. The main points are:

1. Current Limitations: Despite their capabilities, LLMs have not produced significant breakthroughs. They are "frozen" in their knowledge and lack the ability to learn from experiences or engage in ongoing background processing like humans do.

2. Day-Dreaming Loop (DDL): To enhance LLMs, the proposal introduces the concept of a "day-dreaming loop," a process where the model continuously combines random concepts from its memory to generate novel ideas. This method would involve a generator model to explore connections and a critic model to evaluate and filter valuable insights.

3. Cost vs. Innovation: Implementing the DDL would incur a "daydreaming tax" due to the potential low success rate of finding useful connections, but this expense might be necessary for innovation and would help differentiate valuable insights from random information.

4. Human Thought Comparison: Unlike LLMs, humans engage in continual learning and thinking, often making unexpected connections during moments of subconscious thought. This process is linked to brain functions like the default mode network, which activates during rest and daydreaming.

5. Challenges: The proposal acknowledges the economic implications of implementing such a system, where users may be reluctant to pay significantly more for the occasional novel insight generated by LLMs.

6. Future Implications: The daydreaming process could create a competitive advantage by generating proprietary training data for improved models. However, the need for costly daydreaming AIs may lead to a shift where expensive models are used to produce data for cheaper, more efficient systems used by most users.

Overall, the proposal suggests that enhancing LLMs through a day-dreaming approach could lead to more innovative and valuable outcomes, despite the associated costs.

The paper titled "VideoConviction: A Multimodal Benchmark for Human Conviction and Stock Market Recommendations" discusses the rise of financial influencers, or "finfluencers," on social media platforms like YouTube. These influencers provide stock recommendations, but understanding their impact requires analyzing various signals, such as tone and delivery style, not just text.

The authors, including researchers from Georgia Institute of Technology and Stanford University, created a dataset called VideoConviction, which contains over 6,000 expert annotations from 457 hours of work. This dataset helps evaluate both multimodal large language models (MLLMs) and text-based large language models (LLMs) in financial discussions.

Key findings include that while multimodal inputs can improve stock ticker extraction (like identifying Apple's ticker AAPL), both types of models often misinterpret investment recommendations, confusing general comments with strong advice. High-conviction recommendations are better than low ones but still do not perform as well as the S&P 500 index fund. Interestingly, an investment strategy that bets against finfluencer recommendations yields better annual returns than the S&P 500, though it carries more risk.

The benchmark created by this research aims to enhance multimodal financial analysis. The dataset and evaluation tools are available for public use.

On July 14, 2025, Cloudflare experienced a 62-minute outage of its 1.1.1.1 public DNS Resolver service, which affected users worldwide. The outage began at 21:52 UTC and ended at 22:54 UTC, leaving many users unable to access the Internet. The issue was caused by a misconfiguration related to legacy systems that manage IP addresses, rather than an external attack.

Cloudflare introduced the 1.1.1.1 service in 2018, and it became popular for its free DNS resolution. The outage was triggered by a configuration error made earlier on June 6, which connected the 1.1.1.1 service to a new, not-yet-active service. When changes were applied on July 14, it caused the 1.1.1.1 service's IP addresses to be withdrawn from production, leading to the outage.

During the incident, DNS traffic dropped significantly, but some services like DNS-over-HTTPS (DoH) remained stable because they used different configurations. After identifying the issue, Cloudflare reverted to the previous configuration, restoring most services by 22:54 UTC.

To prevent future incidents, Cloudflare plans to improve its deployment processes, phase out outdated systems, and implement better documentation and testing standards. They apologized for the disruption and are committed to enhancing service stability.

Summary: The Sound of Inevitability by Tom Renner

In this post, Tom Renner discusses the concept of "inevitabilism," which he learned about from Shoshana Zuboff's book, The Age of Surveillance Capitalism. Inevitabilism suggests that certain futures are unavoidable, leading people to prepare for them instead of questioning their validity. This mindset can dominate conversations, making those who disagree seem out of touch.

Renner highlights how prominent tech figures frame the discussion around AI by suggesting that we must adapt to an inevitable future with it, rather than asking if this future aligns with our desires. He argues against this framing, stating that we do have choices about our future and how technology should be used. Renner encourages readers to think critically about the future they want and to resist being swayed by the idea that certain outcomes are predetermined.

Summary: Designing for the Eye: Optical Corrections in Architecture and Typography

This article by Niko Kitsakis discusses the importance of optical corrections in visual design and architecture, emphasizing how our perception can be influenced by optical illusions. One well-known example is the Müller-Lyer illusion, which shows that two lines of the same length can appear different due to the direction of their arrowheads. Recent research suggests that this illusion can be perceived universally, regardless of cultural background.

The article highlights how artists and typographers, like Paul Renner, understand that visual impressions are essential in design. They prioritize what looks right to the eye over strict measurements, acknowledging that all viewers share similar perceptual biases.

In typography, these optical corrections help letters appear visually balanced and aesthetically pleasing. For instance, the typeface Futura has adjustments that compensate for how we perceive shapes, making letters look more appealing.

Similarly, in architecture, optical corrections are crucial. The Parthenon, a masterpiece of Greek architecture, employed various optical adjustments to create a sense of beauty and life in its structure. These include the curvature of the base and slight tapering of columns, which prevent the building from looking heavy or sagging.

Overall, the article argues that understanding these optical principles is vital for both architects and typographers. It warns against settling for mediocrity in design, advocating for an appreciation of beauty and culture in our creations.

Over the past year, robotics has made significant advancements, particularly with Pi's π0.5 and Tesla's Optimus, which can perform tasks like cleaning and cooking. However, these robots are often seen as mere appliances because they lack expressiveness, which is crucial for natural interactions. Expressiveness helps convey a robot's intentions and emotions, making it feel more alive.

The author, inspired by concepts from Apple's ELEGNT paper and a soft robot called SpiRobs, began developing Shoggoth Mini to explore these ideas further. The process involved several design challenges, such as creating a testbed for the tentacle robot and improving its cable management for easier iteration.

The control system was simplified to allow intuitive manipulation via a trackpad, reducing the complexity of moving the tentacle. This 2D projection became integral to the robot’s operation, allowing for both manual and automated controls.

The robot's perception system used hand tracking and tentacle tracking, and it employed reinforcement learning for more advanced behaviors, like following a user's finger. While the robot maintained expressiveness, the author noted that it sometimes felt less "alive" over time due to predictability.

Looking ahead, the author plans to explore further enhancements, such as adding voice capabilities, expanding the control system, and improving the robot's ability to express itself. The project is open for collaboration and discussion within the robotics community.

Summary of GPUHammer: Rowhammer Attacks on GPU Memories

GPUHammer is a new attack method that demonstrates how Rowhammer vulnerabilities can affect GPU memory, specifically GDDR6 in NVIDIA's A6000 GPU. This attack can cause bit flips in memory, allowing one user to corrupt another user’s data on shared GPUs. The researchers showed that a single bit flip could drastically reduce the accuracy of deep neural network models from 80% to 0.1%.

Key Points:

1. Rowhammer Overview: Rowhammer is a flaw where quickly accessing one row of memory can cause errors in adjacent rows. While this issue has been studied in CPUs, this research focuses on GPUs, which have unique challenges.

2. Challenges with GPUs: GDDR6 memory has higher latency and faster refresh rates compared to DDR4 in CPUs, making it harder to exploit Rowhammer. Also, the way memory addresses are mapped in GPUs complicates the attack.

3. Attack Method:

   • Mapping Memory: The researchers reverse-engineered how GPU memory addresses correlate to physical memory locations to identify vulnerable rows.
   • Maximizing Attacks: They used a multi-threaded approach to increase the speed of memory access, necessary for successful attacks.
   • Bypassing Defenses: They synchronized their attacks with memory refresh cycles to evade in-built defenses.

4. Results: The researchers successfully induced bit flips in multiple memory banks of the A6000 GPU and demonstrated the ability to degrade the performance of machine learning models significantly.

5. Mitigation Strategies:

   • Enabling Error Correction Codes (ECC) can help correct single-bit errors but may slow down performance by up to 10%.
   • Future GPU designs could include more effective protections against such vulnerabilities.

6. Current Vulnerability Status: The attack was confirmed on the NVIDIA A6000; other GPUs tested did not show the same vulnerabilities. Newer models like the H100 and RTX 5090 may be safer due to advanced error correction features.

This research highlights a significant security concern for GPUs, particularly in cloud-based environments where resources are shared among users.

The Model Context Protocol (MCP) server is an open-source tool that helps language models (LLMs) understand time better. Unlike typical setups that connect LLMs to external data, MCP enhances their capabilities by providing them with a sense of time. It features six functions, such as current_datetime and time_difference, which enable LLMs to recognize pauses and analyze the structure of conversations.

MCP runs quickly, either locally in under 60 seconds using Python or through a hosted demo. Beyond time, MCP can potentially incorporate other signals like location, weather, device status, calendar events, and even biometric data to improve collaboration.

The creator invites feedback and ideas on additional features and functionalities for MCP. For more details, there's a full backstory available online.

The article argues that true meritocracy cannot exist without incorporating randomness, or "lottocracy," into the selection processes for authority positions. It explains that traditional metrics used to measure qualifications, such as election success, often lead to corruption and the selection of individuals who are skilled at gaming the system rather than being genuinely qualified.

Key points include:

1. Corruption of Metrics: When selection criteria are transparent, they can be manipulated, undermining the legitimacy of authority and governance.

2. Problems with Traditional Selection: Positions of power often go to those who are charming or well-connected rather than those who are competent.

3. Role of Randomness: Introducing random selection can eliminate advantages gained through manipulation, ensuring that authority is held by those who truly merit it.

4. Practical Applications: Suggestions for implementing randomness include creating randomly selected oversight boards for hiring and appointments, and using stratified sampling for committees to ensure diverse perspectives.

5. Addressing Concerns: Common objections to randomness, such as fears of incompetence, can be mitigated through training and transparent processes.

6. Historical Examples: Successful randomness-based governance examples include juries and ancient Athens, which used lottery systems for public roles.

Overall, the article advocates for randomness in governance as a way to maintain integrity and prevent corruption, allowing real talent and ability to thrive.
