In Kawara, a small town in Fukuoka Prefecture, children are excitedly collecting trading cards featuring local middle-aged men, known as ojisan, instead of typical fantasy characters or celebrities. This unique card game, created by Eri Miyahara from the Saidosho Community Council, aims to connect kids with their community's elders.

The game features 47 cards with various ojisan, each having special abilities and humorous elements. For example, one card showcases a former fire brigade chief, while another highlights a local soba noodle expert. The most popular card belongs to a former prison officer who has become a local hero among the children.

Initially designed for collecting, the game evolved into a competitive format where kids compare card strengths and engage in battles based on the characters' real-life contributions to the community. This has led to increased participation in local events, doubling the involvement of children in community activities since the game's launch.

The cards are handmade and sold exclusively at the Saidosho Community Center, with packs costing between ¥100 and ¥500. Despite their limited availability, the demand remains high, as many kids save up to get their favorite shiny versions of the cards.

In recent weeks, Google and OpenAI introduced advanced image generation capabilities using multimodal AI. Previously, AI-generated images were created by simpler systems responding to text prompts from language models. This often resulted in poor-quality images with errors, such as including unwanted elements like elephants in an image about a room without them.

Multimodal image generation allows AI to create images more intelligently, piece by piece, similar to how it generates text. This leads to clearer, more accurate results. For instance, if you ask for an infographic, the AI can respond effectively to your feedback and make adjustments, like altering colors or fixing text errors.

These new systems can produce nearly any image based on prompts, enabling creative tasks like transforming hand-drawn sketches into advertisements or modifying existing photos. They also open up various applications, such as creating visual recipes or game textures.

However, the rise of these technologies raises important questions about artistic ownership, copyright, and potential misuse, such as deepfakes. As AI continues to evolve in visual media, it will be crucial to establish clear guidelines to address these challenges and ensure responsible use of these powerful tools.

Researchers have found that intelligence in vertebrate animals, such as birds and mammals, likely evolved independently at least twice. This challenges the long-held belief that both groups inherited complex neural pathways from a common ancestor. Recent studies indicate that while the brain circuits of birds and mammals are similar, they developed in distinct ways. Birds demonstrate advanced cognitive abilities despite having different brain structures from mammals, leading scientists to consider the evolution of intelligence as a result of independent developments in both lineages.

Historically, scientists underestimated bird intelligence due to their unique brain anatomy. However, research from the 1960s onward began to reveal similarities in the neural circuits of birds and mammals, sparking debate about whether these similarities were inherited or evolved separately. New studies using advanced techniques, such as single-cell RNA sequencing, have shown that while the final brain structures may resemble each other, they developed from different embryonic origins.

These findings suggest that intelligence can arise through various evolutionary paths, highlighting the complexity of brain development across species. Understanding these processes can provide insights into the nature of intelligence itself and could inform future research in artificial intelligence.

Rollie Free set the world motorcycle speed record of 150.313 miles per hour on September 13, 1948, at the Bonneville Salt Flats in Utah. To reduce wind resistance, Free rode his Vincent HRD Black Shadow in a horizontal position while wearing only swim trunks. A famous photo of this moment, taken by LIFE photographer Peter Stackpole, has become iconic in motorcycle history. Although Free's record has since been surpassed—now at 376.363 miles per hour set by Rocky Robinson in 2010—the image of Free remains one of the most celebrated in the sport.

The IBM System/360, launched in 1964, was a groundbreaking mainframe series that transformed the computing industry and how businesses operated. IBM invested $5 billion (equivalent to about $40 billion today) in developing this product, which aimed to solve compatibility issues faced by users of previous models, specifically the IBM 1401.

Before the S/360, many customers struggled with outdated systems that couldn't be upgraded without significant costs and effort. IBM faced internal conflicts between engineering teams that hindered progress. To unify efforts, IBM's leadership forced collaboration among rivals within the company, leading to the creation of a compatible and expandable family of computers.

On April 7, 1964, IBM announced the S/360, introducing 150 new products, including six computers and numerous peripherals. Its key feature was compatibility—customers could upgrade their systems without rewriting software. The announcement generated immense interest, with over 100,000 orders placed shortly after.

Despite initial production delays and software issues, the S/360 went on to dominate the market, driving significant growth in the computing industry. By the early 1970s, IBM's market position was solidified, and the company doubled its workforce and revenue. The S/360 not only changed IBM but also shaped the future of computing, making it a pivotal moment in technology history. After this experience, IBM's leadership vowed to never undertake such a massive project again.

Summary of Neuroplasticity and Neural Graffiti:

Neuroplasticity allows pre-trained language models (LLMs) to adapt in real-time without the need for retraining. The "Spray Layer" is an experimental addition that combines elements from liquid neural networks and transformer models. This layer injects memory traces into the model's final stages to influence its behavior and how it generates responses.

Key points include:

• Functionality: The Spray Layer alters the model's internal state gradually through interactions, which helps it remember past information and change its thinking patterns.
• Output Influence: While it won't guarantee specific word outputs, it encourages the model to focus on certain concepts over time. For instance, if you express love for dogs, the model may start to reflect dog-related themes in its responses.
• Tracking Effects: Users can measure how much the memory layer influences the model's outputs.
• Manifest Goals: The aim is to enhance the AI's personality and curiosity by enabling it to remember past interactions, leading to a more self-aware behavior.

However, using this technology may result in highly specialized behaviors in deployed models, making it less suitable for typical business applications. Instead, it can create unique digital personas.

The article discusses how removing multiplayer features from Unreal Engine can save memory, particularly for single-player games. The author appreciates Unreal's integrated multiplayer capabilities but notes that this can lead to unnecessary memory usage in single-player projects.

While unused code typically doesn’t affect performance, some multiplayer-specific data still occupies memory in single-player games. The author discovers that certain multiplayer data, like component attachments, can take up significant space—up to 328 bytes per actor. By modifying the engine to exclude these multiplayer features, the memory size of an actor can be reduced from about 1088 bytes to 760 bytes.

However, implementing this optimization is complicated. The author initially considered using preprocessor macros for a cleaner solution but encountered issues with Unreal's Header Tool (UHT) not supporting this. Instead, they opted to manually comment out the unused variables, which is a tedious process.

In total, this optimization could save around 392 bytes per actor, which may not seem substantial unless working with a high number of actors. For large projects with over 100,000 actors, this could lead to significant memory savings. However, for most projects, the author suggests that there are more effective ways to optimize memory usage.

A new report from the energy thinktank Ember reveals that clean energy now accounts for 40% of the world's electricity, a level not seen since the 1940s. This milestone is largely due to a significant increase in solar power, which has doubled in three years and now contributes 7% of global electricity. Despite this growth, fossil fuel electricity demand rose by 1.4% last year due to increased needs from air conditioning, AI, and electric vehicles, leading to higher emissions.

Solar power is the fastest-growing electricity source, but it is still behind wind (8%) and nuclear (9%). China is a major player, contributing over half of the new solar capacity, even as it continues to expand coal power. The report emphasizes that while clean energy is growing, fossil fuel use is also increasing due to rising electricity demand, especially during heatwaves. However, Ember anticipates that clean power growth will eventually surpass demand, reducing reliance on fossil fuels.

In November 2020, during the COVID-19 pandemic, Brazil's Central Bank introduced Pix, a digital payment system that allows users to send money instantly and for free. It quickly became popular because it minimized physical contact, which was important at the time. Users can send money using a recipient's national ID number, phone number, or a QR code. By 2024, Pix became Brazil's most widely used payment method, surpassing cash and cards. The number of transactions grew from 9 billion in 2021 to 63 billion in 2024, totaling 26 trillion reais (about $4.5 trillion). Brazil has seen the fastest adoption of such a system in the world.

Summary: A Supermarket Bag And a Truckload Of FOMO

The author shares their frustrating experience while trying to develop an app using Tailwind CSS. They initially struggled with CSS edits on an old Mac Pro and faced challenges when upgrading to Tailwind 4, which required modern CPU instructions that their machine did not support.

After spending days troubleshooting, they switched to using Tailwind’s CDN for a temporary solution but encountered issues with missing CSS styles. Despite a new version of Tailwind being released, it still did not work on their machine.

Feeling overwhelmed, the author decided to buy a newer Mac Studio, which allowed them to finally see their app's design come to life. However, this experience led them to criticize the trend of using new technologies out of fear of falling behind in the industry (FOMO). They argue that many developers feel pressured to adopt the latest tools, often leading to frustration and inefficiency.

The author emphasizes the importance of using familiar technologies that align with one's goals rather than chasing trends. They conclude that building should be prioritized over following influencer-driven tech advice, advocating for a more thoughtful and personal approach to technology choices.

In New Delhi's Nehru Place, technicians like Sushil Prasad are reviving old laptops by combining parts from discarded devices, creating affordable "Frankenstein" laptops for students and workers who can't afford new ones. This repair culture is thriving despite challenges from global tech companies that make repairs difficult by limiting access to spare parts.

Technicians often source components from e-waste markets, like Seelampur, which processes tons of electronic waste daily. While this salvaging provides essential materials, it also exposes workers to toxic substances.

The Indian government is considering right-to-repair laws to support this industry, but progress is slow. Many believe that formalizing the repair sector could reduce waste and increase job opportunities. For now, repair technicians continue to address the needs of India’s growing digital economy, proving that there is a strong demand for affordable tech solutions.

The article discusses the concepts of arbitrage and equilibrium within the Team Fortress 2 (TF2) economy, which is a digital trading environment.

Key Points:

1. Arbitrage Explained: Arbitrage is the practice of buying low and selling high. It is a goal for traders but can lead to a disappearance of these opportunities as everyone seeks them out, eventually leading to market equilibrium.

2. Digital vs. Analog Economies: In traditional economies, it is difficult to measure price differences and arbitrage opportunities due to limited data. In contrast, digital economies like TF2 have abundant real-time data, allowing for the analysis of trading patterns and opportunities.

3. Barter Economy: TF2 operates as a barter economy where players trade items directly without a standardized currency. This can complicate trades since both parties must want what the other is offering.

4. Equilibrium in Economics: Equilibrium is a state where supply and demand balance each other, and there are no arbitrage opportunities left. It can be static (no change) or dynamic (predictable changes).

5. Measuring Equilibrium: The article provides a simplified example with four items to illustrate how equilibrium can be determined through relative prices. If prices are not aligned, arbitrage opportunities arise, which can lead to changes until equilibrium is reached.

6. Complexity in TF2: The TF2 economy has over 35,000 items, resulting in a vast number of potential prices and making it challenging to determine a single price for each item.

7. Real-Time Data Advantage: Unlike traditional economies, the TF2 economy can be continuously monitored, revealing that it often operates far from equilibrium, indicating many arbitrage opportunities exist.

Overall, the TF2 economy is a unique example of a digital barter system that allows for detailed economic analysis thanks to its rich data environment.

A new technology called Compressed Air Supercharging (CAS) is gaining attention in drag racing. This method, pioneered by Dale Vaznaian, uses compressed air stored in tanks to force oxygen into engines without requiring horsepower or exhaust gases. This setup can provide denser, cooler air, which can lead to better performance with lower boost levels (around 10 psi), making it easier on engine components.

Some racers, like Tina Pierce and Dave, use CAS in their drag trucks, achieving impressive horsepower with minimal refills. Others, like Ryan Mitchell, are transitioning from traditional superchargers to CAS and finding similar performance. While the technology is still new and met with skepticism, it shows promise for enhancing racing performance and could potentially change the landscape of power adders in the future.

In the 1980s, software was downloaded through television broadcasts, much like it was with radio. This article explores two interesting methods used for these TV software downloads during that era.

Television shows in the UK, especially from the BBC, taught viewers coding and electronics, which led to the idea of broadcasting software. One technique, called Teletext, took advantage of the brief moments when the TV screen was blank during frame transitions. This allowed data to be sent without interrupting the show.

Another method used a photodiode, a device that could read light changes on the screen. By placing it over a patterned area on the TV, it could convert those changes into computer code. Although this method had a slow data transfer rate, it was innovative for its time.

A notable advancement was Visicode, developed by John and Richard Billingsley. It improved data transmission by encoding multiple bits per frame using narrow stripes on the screen.

Both Teletext and Visicode are now outdated but demonstrate clever uses of technology. Some of this old data can still be found in home video recordings, preserving a piece of computing history.

Git, created by Linus Torvalds 20 years ago, has evolved from a simple project into the most widely used version control system in the world.

Summary: Optimizing Cloudflare D1 Database Queries

Background: The author has been working with Cloudflare Workers and the D1 database, facing several challenges common for frontend developers who are not familiar with database management.

Key Problems Identified:

1. Monitoring: Use the D1 dashboard to find unusual database activity and examine query performance.

2. Batch Requests: Instead of executing multiple database operations separately, combine them into batch requests to reduce response times. For example, use:

   await db.batch([
     db.insert(user).values({...}),
     db.insert(tweet).values({...})
   ]);
   

   This method minimizes the number of REST requests.

3. Updating Records: Avoid including the ID field in update operations to prevent unnecessary row reads, which can significantly increase the load on the database.

4. Efficient Counting: Avoid using count queries that scan all rows. Instead, use cursor-based pagination without total counts.

5. Managing Joins: Be cautious with multi-table joins, as they can lead to excessive row reads. Split complex queries into smaller ones and perform data handling in application logic.

6. Bulk Inserts: Use a single insert statement for multiple records instead of inserting them one by one. However, be aware of SQLite’s limit on the number of parameters per query, which requires chunking larger batches.

Conclusion: Server-side issues can greatly impact performance and costs, so thorough monitoring and testing are essential. A systematic approach to identifying and resolving database problems is crucial for optimization.

A new type of ecosystem, made up of non-native species, has developed on the Hawaiian island of O'ahu due to human activities. These "freakosystems" provide a glimpse into the future of our planet as they show how ecosystems can change dramatically.

O'ahu's forests, once rich with native plants and animals, now mostly contain species from around the world, brought in by settlers.

   • Data Wiping: Use specialized data-wiping software to securely erase hard drives. For devices with solid-state drives, enable full-disk encryption first.
   • Physical Destruction: For highly sensitive data, physically destroying the storage device is the safest option, although it makes the device unsuitable for resale.
   • Certified Recycling: Use reputable e-waste recyclers that follow strict data destruction protocols to ensure your data is protected.
   • Safe Selling/Donating: Always perform a thorough data wipe before selling or donating devices.

4. Legal Compliance: Businesses must adhere to data protection laws to avoid penalties for improper disposal of sensitive information.

Taking these precautions can help prevent identity theft and data breaches while ensuring responsible recycling of electronic devices.

Summary: The Rise of Microcomputers and Don Tarbell's Contributions

In the late 1960s, Don Tarbell, a computer enthusiast from Alabama, began selling DIY computer components and quickly gained expertise in building home computers. By 1972, he had created a functional computer system with an 8-bit processor. The launch of the Altair 8800 kit in 1975 marked a turning point, enabling hobbyists to create personal computers. Many enthusiasts, including Tarbell, formed communities to share knowledge and innovations.

Tarbell developed the Tarbell cassette interface, allowing users to store data cheaply on cassette tapes, which helped address a major limitation of the Altair. This innovation, along with others from various small companies, contributed to the rapid growth of the microcomputer industry.

As competition increased, new companies emerged, offering improved hardware and software solutions. Notable figures like Bill Gates and Paul Allen saw the potential for software and created a BASIC interpreter for the Altair, leading to the establishment of Microsoft.

By 1976, the market was thriving with a variety of personal computers, software, and accessories, transforming the landscape from a niche hobby to a burgeoning industry. This period was characterized by innovation and entrepreneurial spirit, setting the stage for the future of personal computing.

The article discusses new research trends in cartography, which is the art and science of map-making. Traditionally, cartography was more artistic, but since the 1950s, it has shifted towards a scientific approach. In the 1970s, researchers began to view maps as communication tools, aiming to create the most effective map that minimizes confusion for users.

Recently, with advancements in computer technology, researchers like Alan MacEachren have proposed a new concept called "cartographic visualization." This approach allows maps to not only communicate existing information but also to uncover new patterns in spatial data. Instead of striving for a single "best" map, modern tools enable the creation of multiple representations that can answer various research questions.

Overall, this evolving perspective in cartographic theory emphasizes data exploration and integrates insights from computer graphics, cognitive science, and semiotics. It aims to enhance our understanding of maps and improve map-making practices.

About nine months ago, I and three friends started a company to use AI for monitoring large codebases for security issues, hoping to replace some functions of human security testers. We began working on this project in June 2024. After releasing our initial tool, we saw some improvement in performance thanks to a new AI model, Claude 3.5. However, subsequent AI releases did not significantly enhance our tool's ability to identify vulnerabilities.

Despite the industry's claims of improved AI performance, my experiences and conversations with other founders suggest that these advancements do not translate into real-world usefulness. There is a lack of public benchmarks for evaluating AI in security contexts, making it hard to measure improvements accurately.

Many AI companies might exaggerate their models' capabilities for competitive advantage, leading to skepticism about their honesty regarding performance metrics. While some benchmarks show slight improvements, they often fail to assess practical applications effectively.

My company uses AI to help overwhelmed security engineers manage numerous security issues in their software. However, the AI often struggles to follow specific instructions and tends to highlight potential problems rather than confirm code safety, which is not helpful for our needs.

In summary, while AI models might appear to improve in controlled tests, this does not equate to better performance in real-world tasks, particularly in complex scenarios like security testing. It’s crucial for the industry to develop more effective assessment methods to understand AI's actual capabilities and limitations.

Summary:

On April 2, 2025, it was reported that DeepMind's AI system, called Dreamer, successfully learned to collect diamonds in the video game Minecraft without any prior instruction. This achievement is significant because it demonstrates the AI's ability to generalize knowledge across different situations, moving closer to the goal of creating advanced AI systems.

Minecraft is a complex game with randomly generated worlds, requiring players to perform multiple steps to gather resources and ultimately find diamonds. Dreamer uses a method called reinforcement learning, which allows it to learn through trial and error, exploring the game independently.

A key feature of Dreamer is its “world model,” which helps the AI predict the outcomes of its actions without needing to perform them in the game. This capability could potentially apply to real-world tasks, where trial and error can be costly. The success of Dreamer in Minecraft was an unexpected but effective way to test its learning algorithm.

Camera manufacturers use different RAW formats, leading to confusion and compatibility issues for users. While JPEG files are easy to share, RAW files provide richer data for editing but come in various proprietary formats, such as Canon's CR3, Nikon's NEF, and Sony's ARW. Adobe created a universal RAW format called DNG to address these issues, but only a few manufacturers have adopted it.

Some smaller brands use DNG for its flexibility and ease of use, while larger companies stick with proprietary formats to maintain control over image quality and processing. Proprietary formats can offer unique features and optimized performance, but they can also lead to challenges with software compatibility, especially for new cameras.

Ultimately, users often need specialized software to edit RAW files, and early adopters may face delays in software support for new camera formats. Although an open format like DNG would simplify things, the current landscape is unlikely to change significantly, leaving users to navigate a mix of proprietary formats.

Summary:

Researchers at the University of Michigan have developed a new method for manufacturing electric vehicle (EV) batteries that allows them to charge five times faster in cold temperatures, down to -10°C (14°F). This breakthrough addresses common issues that deter potential EV buyers, such as reduced range and slower charging in winter.

The new battery design includes a special coating on the electrode and microscale channels that prevent lithium from building up on the surface during charging. This solution allows the batteries to maintain 97% of their capacity even after being fast-charged multiple times in cold conditions.

The research aims to make it easier for EV manufacturers to implement this technology without major changes to existing production processes. Currently, many consumers are hesitant to buy EVs due to concerns about battery performance in winter, with a drop in interest from 23% to 18% in just one year. The team is now working on making the technology factory-ready with support from state funding and has applied for patent protection.

Mike Waltz, Donald Trump's national security adviser, accidentally added journalist Jeffrey Goldberg to a White House Signal group chat discussing US military plans in Yemen. This mistake happened because Waltz incorrectly saved Goldberg's phone number under another contact months earlier. An internal investigation revealed a series of errors that began during the 2024 campaign and went unnoticed until the group chat was created.

Trump briefly considered firing Waltz, mainly because he disliked Goldberg and wanted to avoid giving the media satisfaction in forcing his resignation. However, he ultimately decided against it, partly due to the investigation's findings and Waltz's apologies.

The White House's IT office conducted a review and found that Waltz's phone had saved Goldberg's number during an automatic update. The error came to light when Waltz was trying to add another official to the chat. Despite the incident, Trump has publicly supported Waltz, and the administration had authorized the use of Signal for secure communications across agencies, as there was no alternative platform available.

Tunnock's teacakes, once banned from RAF flights due to a cockpit incident where they exploded, have been cleared for air travel again. The ban originated 60 years ago when a pilot and student forgot unwrapped teacakes in the cockpit, leading to a sticky mess during an emergency. Recently, tests conducted in an altitude chamber showed that while the teacakes can crack at high altitudes, they do not explode and pose no safety risk.

The RAF recommends that pilots keep the teacakes frozen and in their wrappers until they are ready to eat them. A Tunnock's representative expressed that it's amusing to think fighter pilots would worry about teacakes, but they are glad the treats are now officially approved for consumption in-flight.

The LA Report offers daily news updates, highlighting critical stories for readers. Following the Palisades Fire in January, firefighting planes dropped fire retardant to control the blaze. However, testing by USC and LAist revealed harmful heavy metals, such as lead and arsenic, in the fire retardant used. Perimeter Solutions, the manufacturer, claims their products meet safety standards and that detected metals are naturally occurring and below safety limits. Despite this, safety data sheets provided by the company do not mention the presence of heavy metals, raising concerns about transparency and regulatory compliance.

Experts have noted that while heavy metals can pose health risks, exposure for the general public, such as hikers, is likely low, but caution is advised. The environmental impact is more significant, especially concerning aquatic ecosystems, where runoff from fire retardants can harm wildlife. The U.S. Forest Service has regulations to protect waterways from these chemicals, but violations have been reported.

Overall, there is a need for better transparency regarding the contents of fire retardants and their potential health and environmental risks.

Researchers believe that inside black holes, there may be complex structures known as "supermazes," which consist of tangled strings in higher dimensions. This idea is based on string theory, particularly M-theory, which suggests our universe has 11 dimensions instead of the four we usually recognize.

Supermazes represent how different dimensional strings, called branes, intersect within black holes. Unlike traditional black holes that have distinct boundaries and singularities, these supermazes would be more like "fuzzballs"—objects that behave like black holes but lack certain traditional features.

A recent study describes these supermazes and proposes they might help address the black hole information paradox, which questions how information is preserved when black holes evaporate. The researchers claim that supermazes could retain information through the particles emitted during this process, potentially solving the paradox of information loss associated with black holes.

Overall, this research contributes to the ongoing effort to reconcile general relativity with quantum mechanics, aiming for a comprehensive understanding of the universe's workings.

Catullus was a famous Roman poet known for his complex and passionate poetry, which blends tenderness, aggression, and obscenity. His early death led to public mourning, but most of his work nearly vanished until a single manuscript was discovered during the Renaissance.

His poetry features two distinct sides: one is a bold and emotional young writer, often expressing intense feelings about love and betrayal, particularly in his poems about a woman called Lesbia. The other side is a more sophisticated poet, showcasing refined wit and literary skill in longer, elaborate works.

Catullus’s poems cover a wide range of emotions, from the lighthearted to the deeply personal. He often wrote about everyday experiences, such as love and friendship, while also tackling serious themes like loss and betrayal. The duality of his character is evident in his work, where he can be both vulgar and profoundly poignant.

Despite the challenges of translation, Catullus's work continues to resonate with readers today, capturing the complexities of love and human emotion. His unique style and the raw intensity of his feelings have made him a lasting influence on poets through the centuries. The rediscovery of his poems in the Renaissance revived interest in his work, which remains a significant part of classical literature.
