The working paper titled "Captain Gains on Capitol Hill" by Shang-Jin Wei and Yifan Zhou examines stock trading by U.S. lawmakers. It finds that members of Congress who become leaders see a significant increase in their stock trading performance—47 percentage points higher annually—after they take on leadership roles. This improved performance stems from two main factors:

1. Political Influence: Leaders earn higher returns when their party controls Congress, sell stocks before regulations change, and buy shares in companies that get more government contracts or favorable support from their party.

2. Corporate Access: Their trades often predict positive company news, leading to better returns, especially for firms tied to campaign donors or their home states.

The paper uses detailed transaction data to support these findings. It highlights the potential for lawmakers to benefit financially from their positions through strategic stock trading.

Summary:

The author is developing a game using Rust and has encountered a buzzing sound in their headphones while playing it, unlike when playing other games like Fortnite or Overwatch. They have a decent computer setup but noticed that the buzzing occurs only when rendering the game.

Initially, they suspected a power issue but realized that the buzzing stopped when rendering was disabled. After investigating, they discovered that the buzzing was linked to downloading a "picking texture" from the GPU to the CPU. This texture helps determine what the player clicks on in the game.

Disabling the texture download reduced the buzzing, and testing showed that less frequent downloads also lessened the noise. A discussion with graphics engineers led to the insight that the buzzing was due to heavy GPU work being interrupted by the texture transfer.

To fix the issue, the author changed their approach to only download the part of the picking texture needed for the mouse click, which eliminated the buzzing completely.

3D Gaussian Splatting (3DGS) is effective for creating realistic 3D scenes quickly. However, it's challenging to use it for generating large or endless terrains from a single example. This paper presents a new solution using a tile-based approach. Each tile represents a small area with Gaussian fields that blend together smoothly. This allows for the easy creation of large and diverse terrains. Additionally, the paper includes improvements for rendering these terrains quickly, making real-time visualization possible.

The text reflects on the early days of the Rust programming language, specifically around 2012-2013, and compares it to its current state. Here are the key points simplified:

1. Installation: Initially, Rust required building from source or using a specific installer on Windows, which was complicated compared to today's simpler tool called rustup.

2. First Program: The classic "Hello, world!" example used a different syntax and lacked modern error messages. Early Rust lacked features like macros and had less clear syntax for printing outputs.

3. Syntax and Types: Many elements from the early language, such as types and syntax for integers, have changed. For example, usize and isize were named differently, and there were no modern concepts like ownership and borrowing.

4. Control Flow and Functions: The early version included unique control flow mechanisms and implemented functions differently. The way closures worked and how they were called has evolved significantly.

5. Memory Management: Early Rust had a different memory model with types that are now obsolete, making it more complex to manage memory. The concepts of borrowing and references were also less developed.

6. Error Handling: The handling of errors (then called exceptions) was rudimentary, and the language had no built-in way to catch panics effectively.

7. Library Management: There was no cargo (the package manager for Rust), and crate management was done through a more manual process.

8. Structs and Enums: Structs were similar to C structs, and enums lacked some of the scoping features present in modern Rust.

9. Lifetimes and Aliasing: Lifetimes were less flexible, and aliasing rules were more complicated, leading to potential issues that have since been resolved in newer versions.

10. Conclusion: The author appreciates the progress Rust has made, highlighting improvements in user-friendliness and simplicity, acknowledging the contributions of the Rust community over the years.

Overall, the text illustrates how Rust has evolved from a complex and less intuitive language to a more streamlined and user-friendly programming tool.

Scientists are exploring the potential of a tiny microbe called Chroococcidiopsis to produce oxygen on Mars, addressing one of the biggest challenges for human survival on the planet: breathing. This microorganism can thrive in conditions similar to Martian soil and generates oxygen as it grows.

Laboratory tests showed that Chroococcidiopsis not only survives but thrives in harsh environments, including high radiation and low pressure, and can repair its DNA if damaged. This resilience suggests it could help create a self-sustaining oxygen supply for future Mars colonies, reducing the need to transport oxygen from Earth.

However, challenges remain, such as how to cultivate these microbes at scale on Mars and protect them in a volatile environment. The research also raises questions about the possibility of life existing elsewhere in the solar system, as extremophiles on Earth have shown that life can adapt to extreme conditions.

Overall, using microbes like Chroococcidiopsis could be a promising part of closed-loop systems for food, water, and oxygen production on Mars, making human settlement more feasible without relying solely on Earth.

On December 2, 2025, it was revealed that HBO Max's 4K restoration of the acclaimed series "Mad Men" has significant quality control issues. While the first four seasons were filmed traditionally, the final three were shot digitally, and the entire series was originally mastered in 1080p HD. Fans were excited for the 4K release, but problems became evident when a viewer noticed visible mistakes, such as a fake puke hose and crew members appearing in a scene that should have been edited out.

This issue is separate from other common restoration problems, where shows are reframed to fit a new aspect ratio, but in "Mad Men," the show was already in the correct 16:9 format. The episode titles were also mixed up, but HBO Max is correcting them. This restoration error has unintentionally revealed the extent of digital effects used in the show, including alterations to make it appear as if it was filmed in 1960s New York instead of 2000s Los Angeles. Overall, these mistakes highlight flaws in the restoration process and raise concerns about the preservation of television history.

Billie's Story: The Creation of SnoutCover

Billie, a pitbull, faced a tough challenge when she was diagnosed with Discoid Lupus Erythematosus (DLE), an autoimmune disease that affected her nose. Her nose lost pigment, became painful, and was worsened by sunlight, making her condition a struggle for both her and her owners.

The treatment options were frustrating. Medications were quickly licked off, and other solutions like sunscreen and fabric shields didn’t work. This led her owners to design a new solution: SnoutCover, a protective device for her nose.

Using a 3D printer, they went through multiple prototypes to create a comfortable, breathable, and effective cover. After many iterations, they achieved a design that protected Billie’s nose and allowed her to heal. Over five months, Billie's condition improved significantly, and she became pain-free, returning to her playful self.

The positive response to Billie's recovery inspired her owners to share the SnoutCover design for free, hoping to help other dogs with similar issues. SnoutCover is made of soft, flexible material with ventilation holes to keep the dog's nose moist while protecting it from sunlight.

This journey highlighted the love and determination of dog owners and emphasized that there is hope for pets suffering from DLE. The SnoutCover design can be found on Makerworld for others to use.

The article discusses concerns about the potential for an AI datacenter crash, comparing it to the telecoms crash of the early 2000s. While there are similarities, the author argues that the fundamentals are different.

Key Points:

1. Telecoms Crash Overview: In the 2000s, massive investments were made in telecom infrastructure based on overestimated demand. By 2002, only a small percentage of the infrastructure was used, leading to a crash.

2. Demand Miscalculation: Telecom companies significantly overestimated internet traffic growth, leading to excessive infrastructure spending. Improvements in technology made much of this infrastructure unnecessary before it could be utilized.

3. AI Infrastructure Dynamics: Unlike telecoms, AI datacenters are not experiencing the same level of exponential efficiency improvements. GPU performance gains are slowing, and power consumption is increasing, which could limit the ability to meet demand.

4. Growing Demand for AI: Demand for AI is potentially underestimated, especially with the rise of AI agents that could consume much more data than traditional usage patterns.

5. Capital Expenditures (CapEx): AI-related CapEx is growing rapidly but is not as dramatic as some reports suggest. Companies are investing heavily, but much of this spending is a continuation of previous trends rather than a new boom.

6. Forecasting Challenges: Predicting future demand for AI infrastructure is difficult. Companies face a dilemma: underestimating demand can hurt user experience, while overestimating can lead to wasted investments.

7. Differences from Telecoms: The key differences between the telecoms crash and the current AI situation include the nature of supply and demand dynamics, as well as how infrastructure is utilized over time.

8. Potential for Correction: While a short-term correction in AI datacenters could happen if demand grows slower than expected, the underlying dynamics suggest that the infrastructure will still be used, just at a different pace.

9. Conclusion: The author believes that while there may be challenges ahead for AI datacenters, the situation is not analogous to the telecoms crash. The growth in AI demand and the nature of the technology suggest a different outcome, even if there are bumps along the way.

The study published in "Nature Human Behaviour" explores how different cultures mentally represent music, focusing on rhythm. Researchers conducted experiments with participants from 39 groups across 15 countries, including both urban and Indigenous populations. They asked participants to reproduce rhythms, which allowed the researchers to analyze the patterns and biases in their reproductions.

Key findings include:

1. Common Features: All groups displayed a tendency to gravitate towards specific 'simple' integer-ratio rhythms (like 1:2 or 2:3) in their reproductions, suggesting a universal aspect of music cognition.

2. Cultural Variations: While there are commonalities, the significance of different integer ratios varied between groups, reflecting local musical traditions and practices.

3. Discrete Modes: Each participant group showed distinct peaks in their rhythm reproductions, indicating that they recognized certain categories of rhythms, which can help stabilize musical systems despite cultural differences.

4. Cross-Cultural Insights: The study highlighted that while some rhythmic representations are universal, the specific preferences and practices can vary significantly across cultures.

5. Impact of Western Influence: University students and online participants from various countries exhibited less diversity in their rhythm representations, often resembling US participants more closely due to exposure to Western music.

In summary, this research provides evidence of both shared cognitive mechanisms in music perception and notable cultural variations in rhythm representation.

Summary of "Counter Galois Onion: Improved encryption for Tor circuit traffic"

The Tor network is updating its encryption system by replacing an old algorithm, known as "tor1," with a new design called Counter Galois Onion (CGO). This change aims to protect users from various online attacks and improve future encryption efforts.

Key Points:

1. Current Encryption Issues: The existing tor1 algorithm has several vulnerabilities, particularly susceptibility to tagging attacks, which allow attackers to trace user traffic. It also lacks forward secrecy (the ability to keep past communications secret, even if current keys are compromised) and uses a weak 4-byte authenticator.

2. What is CGO?: CGO is a new encryption design that addresses these issues:

   • It prevents tagging attacks by making any tampering with the encrypted data unrecoverable.
   • It ensures forward secrecy by changing encryption keys with each new message.
   • It replaces the short authenticator with a longer, more secure 16-byte tag.

3. Design Improvements: CGO uses a construction called Rugged Pseudorandom Permutation (RPRP), which enhances security while keeping processing costs manageable. This design allows for efficient encryption and minimizes bandwidth use.

4. Current Implementation Status: The implementation of CGO is in progress for both the Arti (Rust) and C versions of Tor. Future steps include making CGO the default encryption method and optimizing it for performance.

5. Acknowledgments: The update is made possible by contributions from various researchers, cryptographers, and supporters of Tor.

This overhaul marks a significant improvement in Tor's encryption capabilities, enhancing user privacy and security online.

The text discusses an experiment with the classic game DOOM and its sound capabilities. Many players know that DOOM has sound drivers that work directly with sound hardware, but it also includes a basic PC Speaker driver that is often ignored because it only plays simple sound effects poorly. There was a belief that using this driver for music would be too demanding for older PCs, especially the 286 models.

However, the author, curious about this limitation, created a patch to enable music through the PC Speaker on faster systems, like the 486. They developed a new file format called "pcsp" for playing tunes efficiently with minimal processing. The patch involved adding a music mixer to the existing sound server, and testing showed no significant performance issues when running the game with the patch.

The author plans to release the patch publicly soon but wants to implement more features and fix some issues first. Currently, only one soundtrack, E1M1, is ready.

Japanese game developers are facing a significant challenge due to a drastic price increase in font licensing. One major provider, Fontworks LETS, has raised its annual plan cost from about $380 to over $20,500, discontinuing its previous game license plan. The new plan from Monotype, Fontworks' parent company, does not offer local pricing for Japanese developers and has a user limit that may not suit larger studios.

This situation is particularly tough because finding affordable fonts that can accurately display Japanese characters like Kanji and Katakana is already complicated. According to the CEO of Indie-Us Games, this issue, while not widely known, has become critical. UI/UX designer Yamanaka noted that it could disrupt live service games, requiring studios to re-test and validate existing content if they switch to different fonts. Some studios might even have to rebrand if they can no longer afford their current font licenses.

The article discusses the impressive performance of SQLite, particularly in handling transactions per second (TPS) with a large number of rows. It argues that SQLite's design, which includes being embedded and having a single writer, actually enhances its scalability rather than hindering it.

Key Points:

1. SQLite's Strengths: Despite common criticisms (like lacking Multi-Version Concurrency Control or MVCC and being designed for mobile apps), SQLite performs exceptionally well with high transaction rates.

2. Benchmark Setup: The benchmarks were conducted on a MacBook Pro with an Apple M1 Pro chip, demonstrating SQLite's efficiency in executing interactive transactions, which involve running queries and application code sequentially.

3. Transaction Definition: The article focuses on transactions that involve multiple operations (like crediting and debiting accounts), emphasizing the importance of being able to roll back changes if needed.

4. Performance Metrics:

   • PostgreSQL showed a respectable 13,756 TPS under normal conditions but dropped significantly with network latency.
   • SQLite, without network delays, achieved an impressive 44,096 TPS and even higher with batching techniques.

5. Amdahl's Law: The author explains how network latency severely limits performance in database systems like PostgreSQL, while SQLite's absence of network interaction allows it to outperform in high-load scenarios.

6. Batching and Concurrent Reads: SQLite's single-writer model allows for efficient batching of transactions, which can further increase TPS. When combined with concurrent reads, performance can reach over 102,000 TPS.

7. Conclusion: The article illustrates the effectiveness of SQLite in specific use cases, particularly where transactions are frequent and network delays can be a bottleneck. It cautions that while SQLite is powerful, it may not be suitable for all applications, especially those requiring complex database management.

Overall, the article advocates for recognizing SQLite's capabilities and suggests it can be a strong alternative to traditional network databases in certain contexts.

A recent study suggests that Earth's moon may have formed after a collision with a neighboring planet called Theia, which was similar to Earth and formed in the inner solar system. This collision, which happened around 4.5 billion years ago, caused a massive impact that resulted in molten debris from Earth forming the moon. Researchers analyzed samples from the Apollo missions and other terrestrial rocks to find chemical clues indicating that Theia was likely a rocky world close to Earth. The study reinforces the idea that both Earth and Theia originated from the same region of the solar system. However, the exact nature of their collision and how they became chemically similar remains a mystery.

Summary of "A Series of Vignettes From My Childhood and Early Career"

The author shares nostalgic anecdotes about their experiences with programming and the evolution of the software engineering profession over nearly three decades.

1. The Death of Software Engineering: A wise adult warned the author in the 1990s that programming would soon become obsolete as libraries and tools would allow anyone to create software without needing deep skills. However, despite such predictions, the author has continued to thrive in the field, highlighting that new challenges and problem-solving opportunities constantly arise.

2. The Multimedia Age: In the early 1990s, the rise of "multimedia" (sound and video) in software was seen as essential. However, its initial excitement faded, and it became a standard expectation rather than a standout feature.

3. Technological Advances: By 2000, tools like IntelliJ IDE introduced powerful features that made programming easier, leading some to believe programmers would become unnecessary. The author argues that while these tools are helpful, they do not replace the creative and logical aspects of programming.

4. Automation Experiences: The author recounts two instances where they automated tasks at their job—first helping a contractor streamline a migration project and then automating their own web maintenance tasks.

Summary of "Practical Intro to Operational Transformation"

This article discusses Operational Transformation (OT) and Conflict-Free Replicated Data Types (CRDT), two methods used for collaborative editing. It emphasizes that there isn't a single best algorithm for OT; instead, there are various algorithms with different advantages and challenges.

Key Points:

• OT vs. CRDT:

  • OT transforms operations (like insertions and deletions) to maintain a consistent document state among users. It can become complex with multiple users.
  • CRDT allows operations to be applied in different orders without needing central synchronization, ensuring all users eventually see the same document state.

• Complexity:

  • While CRDTs are often viewed as simpler, implementing them efficiently can be complicated. OT can be easier to implement but has challenges, especially with undoing actions.

• Transformation Properties (TP1 and TP2):

  • TP1 ensures that two concurrent operations can lead to the same document state through different application routes.
  • TP2 is harder to satisfy and usually requires operations to be rearranged for proper application.

• Control Algorithm:

  • This determines how to transform incoming operations based on the current document state, managing the context of operations to avoid conflicts.

• Undo Operations:

  • Undoing actions in OT is complex due to the need to track the history of changes accurately. CRDTs handle undo operations more straightforwardly.

• Simple OT Algorithm:

  • A basic OT algorithm is proposed that uses a central server to manage operations and contexts, ensuring simplicity in implementation.

• Real-World Applications:

  • Various implementations of OT and CRDT exist in collaborative tools like Google Docs, and examples of algorithms include CoWord and CoMaya.

The article ultimately underscores the ongoing development and complexity in both OT and CRDT systems, suggesting that neither method is universally superior and that each has its specific use cases and challenges.

The text discusses different types of voltage adjustment circuits, focusing on charge pumps, particularly a voltage halver design.

1. Charge Pumps: These are efficient circuits used to adjust voltage levels in electronic devices. A basic charge pump is a voltage doubler that can be easily integrated into digital chips.

2. How It Works: In a voltage doubler, a capacitor (Cf) charges from the power supply and then transfers its charge to another capacitor (Cout), effectively doubling the voltage. The process can be controlled to minimize voltage ripple.

3. Voltage Halver: The text introduces a more complex charge pump that halves the voltage. It uses two series capacitors (C1 and C2) that initially share the supply voltage evenly. However, when a load is connected, the voltages can become unequal.

4. Using a Flying Capacitor: To maintain equal voltages while providing continuous power to the load, a "flying" capacitor (Cf) moves back and forth between C1 and C2, transferring charge as needed. This allows the circuit to stabilize the output voltage at half the supply voltage, independent of the capacitor sizes.

In summary, the voltage halver is an innovative circuit that uses charge transfer to achieve stable, halved voltage outputs.

The author is concerned about the job prospects for college students, especially those in fields affected by AI. Recent studies show that companies using AI are hiring fewer junior employees, leading to increased unemployment among young professionals. Many students struggle to find their first jobs and feel hopeless about their future.

Through interviews with university staff and students, the author found that while job placement statistics may not reflect the current situation, everyone agrees that networking is crucial for job success. However, many students don’t know how to effectively network or build meaningful relationships. The lack of mentorship from senior engineers is a significant issue, as the tech industry has shifted away from developing junior talent.

AI is taking over tasks traditionally assigned to junior workers, leading to fewer opportunities for hands-on training and mentorship. This could result in a skills gap in the future when senior engineers retire.

The author suggests that individuals focus on building skills that AI cannot replicate, such as relationship-building and collaboration. They encourage students to intentionally nurture key professional relationships and practice these skills while still in school.

In summary, the author sees a need for a shift in how students, professionals, and educational institutions approach career development, emphasizing the importance of relational skills in an AI-driven job market.

The trend of "carspreading," or the increasing size of cars, is growing in the UK and Europe, with larger vehicles being popular among consumers for their practicality and perceived safety. However, cities like Paris are imposing stricter regulations to reduce the number of big cars due to concerns about traffic congestion and pollution. For example, Paris has raised parking fees for heavy vehicles significantly to encourage smaller cars.

Cities in the UK, such as Cardiff, are following suit by increasing parking permit costs for heavier vehicles, citing their higher emissions and safety risks. Critics argue that larger cars can be more dangerous to pedestrians and cyclists, while supporters claim they are necessary for families and businesses.

The popularity of SUVs is notable, with their market share growing significantly over the years. Consumers appreciate their higher driving position and spaciousness. Automakers benefit from producing larger vehicles, as they often have higher profit margins.

While larger vehicles may offer better safety features for occupants, they pose risks to others on the road, and their environmental impact is a concern as they typically emit more pollutants. Suggestions to curb the trend include imposing taxes on heavier vehicles, similar to measures already in place in France.

Despite the push for smaller cars, the market for SUVs remains strong, although there is hope for a resurgence of smaller vehicles in the electric car market.

Summary of "The Rise and Fall of the H-1B Visa"

On September 19, 2025, President Donald Trump announced a shocking $100,000 fee for new H-1B visa applications, significantly altering U.S. immigration policy for skilled workers. This change mainly affects tech companies and applicants from countries like India, which heavily rely on H-1B visas. The H-1B visa, originally intended to attract top talent in STEM fields, has been criticized for allowing companies to replace American workers and suppress wages.

The visa program's issues began in the 1990s when lobbying groups pushed for its expansion. Major corporations and their lobbyists successfully shaped the program to benefit their interests, often claiming labor shortages without sufficient evidence. The program's design allowed companies to hire foreign workers at lower wages, contributing to wage stagnation and job displacement for American workers.

By the early 2020s, H-1B visas were mostly issued to Indian nationals, with many being used by Indian outsourcing firms. The program has been criticized for its random lottery system that doesn't prioritize skill or salary, leading to the hiring of cheaper labor instead of the best candidates.

Recent developments, including Trump's proposed reforms, aim to tighten H-1B regulations and improve wage standards for visa holders. However, the future of the H-1B program remains uncertain, with calls for significant reform or even abolition to better protect American workers and ensure fair labor practices.

Researchers are exploring the field of reverse mathematics to understand why certain complex problems, like the traveling salesperson problem, are so difficult to solve. Traditional methods in computational complexity theory have struggled to provide solid proofs for the hardness of such problems.

In a recent paper, a team of researchers used reverse mathematics to show that many seemingly different theorems are actually equivalent. This approach involves swapping theorems for axioms and proving the relationships between them. For example, they found a connection between the pigeonhole principle and the equality problem in communication complexity, showing that they can prove each other within a specific set of axioms.

This new understanding suggests that various complexity lower bounds are more fundamental than previously thought. However, it also indicates that some theorems may be unprovable under existing axioms. The interest in metamathematics is growing as researchers seek to clarify the foundations of mathematics and tackle long-standing problems in computational complexity.

Summary: Sending Rootless Pings in Rust

Normally, sending a ping requires root access because it involves creating a raw ICMP socket. However, you can send a ping without root by using a UDP socket with an ICMP protocol flag. Here's a simplified guide on how to do this in Rust:

1. Create a UDP Socket: Use the socket2 crate to create a UDP socket for ICMP.

   use socket2::{Domain, Protocol, Socket, Type};
   use std::net::UdpSocket;
   
   let socket = Socket::new(Domain::IPV4, Type::DGRAM, Some(Protocol::ICMPV4))?;
   let socket: UdpSocket = socket.into();
   

2. Send the Ping Packet: Construct the packet without an IP header. Note that Linux and macOS handle identifiers and checksums differently.

   • For Linux: The kernel automatically manages the identifier and checksum.
   • For macOS: You must provide a correct checksum.

   Example packet structure:

   let sequence: u16 = 1;
   let mut packet: Vec<u8> = vec![
       8, 0, 0, 0, 0, 1,
       (sequence >> 8) as u8, (sequence & 0xff) as u8,
       b'h', b'e', b'l', b'l', b'o',
   ];
   
   let checksum = calculate_checksum(&packet);
   packet[2] = (checksum >> 8) as u8;
   packet[3] = (checksum & 0xff) as u8;
   
   socket.send_to(&packet, "1.1.1.1:0")?;
   

3. Receive the Response: After sending, handle the response differently for macOS and Linux, as macOS includes the IP header in the response while Linux does not.

   Example code to interpret the response:

   let mut buffer = vec![0u8; 64];
   let (size, from_addr) = socket.recv_from(&mut buffer)?;
   
   #[cfg(target_os = "macos")]
   const IP_HEADER_LEN: usize = 20;
   
   #[cfg(not(target_os = "macos"))]
   const IP_HEADER_LEN: usize = 0;
   
   let data = &buffer[IP_HEADER_LEN..size];
   let reply_type = data[0]; // should be 0
   let reply_sequence = ((data[6] as u16) << 8) | (data[7] as u16); // should match 'sequence'
   let payload = &data[8..]; // payload should be b"hello"
   

You can expand this implementation to include features like latency, loss, and periodic pings as additional exercises.

Spontaneous symmetry breaking (SSB) is crucial for understanding different phases of quantum matter. Recent research has expanded this idea to mixed states in open quantum systems, identifying two types of symmetry: strong and weak. New types of quantum phases can occur when strong symmetry breaks down to weak symmetry. However, current methods to detect this transition require a lot of copies of the state, leading to a key question: can we efficiently detect this transition in general? The answer is no, as demonstrated in specific cases involving Z_2 and U(1) symmetries. The researchers created examples of mixed states that do not break strong symmetry but are hard to tell apart from those that do, proving that efficient detection methods for this type of symmetry breaking are not possible.

The Partridge Packing Problem is a packing puzzle where the goal is to fit smaller squares into a larger square. Specifically, for a given size ( n ), you need to fit:

• 1 square of size ( 1 \times 1 )
• 2 squares of size ( 2 \times 2 )
• Up to ( n ) squares of size ( n \times n )

These smaller squares must fit into a larger square of size ( \frac{n(n+1)}{2} \times \frac{n(n+1)}{2} ). The problem is inspired by the song "The Twelve Days of Christmas," where the number of gifts corresponds to the squares.

While the total area of the smaller squares matches the area of the larger square, it doesn't guarantee that packing them without overlap is possible. For instance, sizes 2 to 7 have no solutions, but sizes 8 to 33 do have at least one solution. The challenge increases as ( n ) grows.

This post will demonstrate how to model and solve this problem using MiniZinc, a constraint programming language, assuming some prior knowledge of the language.

Over 70 million people worldwide stutter, but most speech recognition systems struggle to accurately understand or transcribe their speech. Traditional methods for correcting stuttering often involve complicated processes that can lead to misunderstandings. This text introduces two new models, StutterZero and StutterFormer, which are designed to convert stuttered speech directly into fluent speech while also predicting the text.

StutterZero uses a specific type of neural network, while StutterFormer employs a dual-stream model that combines acoustic and linguistic features. Both models were trained on special datasets and tested on new speakers, showing significant improvements over existing systems. StutterZero reduced transcription errors by 24% and improved meaning similarity by 31%, while StutterFormer performed even better, with a 28% reduction in errors and a 34% improvement in meaning similarity.

These advancements highlight the potential for better interaction between people who stutter and technology, making speech therapy and AI systems more accessible.
