In 1930, Lima's Escuela Nacional de Bellas Artes introduced a controversial class on Inca art, sparking public debate. Artist Antonino Espinosa Saldaña criticized the class, claiming Inca art didn't exist as a refined civilization and that modern interpretations would result in confusing designs. This debate was part of a larger discussion about Peruvian national identity and the role of Indigenous people, influenced by the Indigenist movement that aimed to connect Peru's artistic future to its pre-Columbian past.

Amid this context, designer Elena Izcue created "El arte peruano en la escuela," a set of drawing workbooks featuring Indigenous motifs, published in Paris in the late 1920s. These books aimed to instill pride in Peru's artistic heritage, reflecting recent archaeological discoveries that shed light on pre-Hispanic cultures. Izcue intended her work to be educational for children and to encourage a sense of nationalism among teachers.

The designs in her workbooks were inspired mainly by earlier cultures, not just the Incas, and often lacked context or cultural significance. Critics argue this simplified the rich diversity of pre-Hispanic societies into a single narrative, making it easier to promote a unified Peruvian identity. Izcue's work became influential in both Peru and abroad, contributing to a revival of interest in Indigenous-inspired art and design.

Summary of the Hashtable Packing Problem

The Hashtable Packing Problem is a complex optimization challenge related to optimizing Magic Bitboards for chess. It involves arranging multiple hashtables in memory to minimize space while avoiding overlaps. This problem is known to be NP-complete, meaning finding the best solution is very difficult, and instead of seeking perfect solutions, we can rely on heuristics to find good enough solutions.

Key Definitions:

• A Hashtable is a list of integers that represent occupied and empty memory buckets.
• A Hashtable Packing involves determining integer offsets for these hashtables to ensure that occupied buckets do not overlap.

The problem is formally linked to the well-known 3-Partition Problem, which is also NP-complete. By demonstrating that solving the Hashtable Packing Problem could also solve the 3-Partition Problem, it is confirmed to be strongly NP-complete.

Magic Bitboards, a technique for chess move generation, face similar optimization issues. The process involves selecting magic factors for different chess pieces and arranging them efficiently in hashtables. However, due to the NP-completeness of the problem, there are no efficient algorithms (polynomial time or otherwise) to guarantee optimal solutions.

Given the complexity and size of the instances involved (like hashtables for 64 squares of rooks and bishops), the problem cannot be easily decomposed. The author suggests that instead of aiming for optimality, using heuristics is a practical approach, as optimal solutions are unlikely to be efficiently achievable.

Fraud prevention is a challenging ongoing task, often described using animal analogies: "whack-a-mole" for constantly addressing new accounts, "cat-and-mouse" for the evolving nature of fraud, and the idea that you don't have to outrun a bear, just make yourself less appealing to fraudsters. While these analogies are colorful, they aren't very practical for real solutions.

At Stytch, they propose a structured fraud prevention framework that evaluates four key areas:

1. Signal gathering: Collecting user activity data.
2. Decisioning: Making informed decisions based on that data.
3. Enforcement: Adjusting user experience based on those decisions.
4. Analysis and feedback: Continuously improving detection methods.

This framework helps identify weaknesses in fraud prevention efforts. For instance, during sophisticated credential stuffing attacks, traditional defenses like IP bans can fail because attackers use residential botnets. Instead, Stytch uses Device Fingerprinting to gather more data about users’ devices and browsers, allowing for better identification of potential fraud.

Stytch focuses on providing useful signals and decision-making support rather than creating a perfect detection system. They aim to empower businesses to make informed decisions about fraud prevention while keeping up with evolving fraud tactics. The framework is a starting point for deeper discussions about various fraud aspects and encourages collaboration in tackling these challenges.

Meta has developed a controversial tracking method called "localhost tracking" that allows it to identify users while they browse the internet on mobile devices, even when using privacy features like VPNs or incognito mode. This technique could lead to fines totaling around €32 billion due to violations of multiple regulations, including GDPR, DSA, and DMA.

Key Points:

1. What is localhost tracking?

   • It lets Meta link users' web activity to their real identities on Facebook or Instagram, even if they haven't logged in or given consent.

2. How does it work?

   • The Facebook or Instagram app runs in the background, "listening" for data from a website that uses Meta’s tracking technology (Meta Pixel). When users visit such websites, the app can secretly receive their browsing data.

3. Legal Implications:

   • Meta faces potential fines for not obtaining proper consent to collect and combine users' personal data.
   • The penalties could be cumulative, amounting to €32 billion based on its global revenue.

4. Wider Impact:

   • This tracking affects a significant number of popular websites, impacting billions of users without their knowledge.

5. User Protection Concerns:

   • The method exploits loopholes in privacy laws, raising serious questions about consent and data protection.

In summary, Meta's localhost tracking could lead to unprecedented fines due to its invasive nature and violation of privacy regulations.

The text introduces a new approach called Reinforcement Pre-Training (RPT) for improving large language models and reinforcement learning (RL). RPT treats the task of predicting the next word (token) in a sentence as a reasoning challenge that is trained using RL. This method allows the use of large amounts of text data without needing specific labeled answers. By focusing on improving the ability to predict the next token, RPT enhances the accuracy of language models. Additionally, it creates a strong base for further fine-tuning with reinforcement learning. The findings suggest that more training leads to better prediction accuracy, making RPT a promising method for advancing pre-training in language models.

Assistant curator Lewis shares his favorite object from the museum's collection: a device used to revive canaries in coal mines. Canaries were used in mines from the late 1800s to detect dangerous gases like carbon monoxide, as they are more sensitive to the gas than humans.

The device, designed by John Haldane, featured a cage that allowed miners to revive a canary if it showed signs of gas poisoning, signaling miners to evacuate. Lewis appreciates that Haldane considered the canary's wellbeing by creating a method to save it, contrasting with the common assumption that canaries were simply expendable.

Lewis favors this object because it shows signs of wear, which adds to its story and context, unlike pristine items. He values the museum's focus on the messy and sometimes troubling aspects of history, as these objects tell deeper stories about scientific innovation and industrial practices.

In addition to the canary device, Lewis mentions other favorite items like unique light bulbs, a Cyberman costume, and fabric from Apollo spacesuits. He encourages visitors to explore the museum's collections online for more information.

The author discusses their journey in implementing the Forth programming language feature called DOES>. Initially, they found it challenging to understand how to implement it, similar to how JavaScript programmers use closures without knowing their workings.

They start by explaining some basic Forth commands, such as CREATE, which defines new words in the Forth dictionary, and DOES>, which modifies a newly created word to execute additional code. The author describes how SHAPE creates a new word and compiles values into it, while MAN is an example word that will run code related to SHAPE.

The key to understanding DOES> lies in its unique temporal aspects during compilation and execution. It executes at three different times: while compiling the word, during the definition of the new word, and when that word is run. This makes DOES> more complex than other Forth words.

The author finally details how they solved the implementation challenges, explaining the steps that occur in the code at each temporal point. They suspect that the reason some Forth implementations like JonesForth didn't include DOES> is due to the requirement for writable and executable memory, which is often restricted in modern systems.

In the end, the author expresses satisfaction in having successfully implemented DOES>, despite the complexities involved.

4. Historical Examples: Figures like John Boyd and Richard Feynman achieved success not by pursuing specific goals but by working within constraints and seeking possibilities.

5. Goals vs. Constraints: Goals are seen as fixed endpoints, while constraints promote adaptability and exploration. Constraints encourage a focus on what one is unwilling to compromise, guiding actions more effectively in uncertain situations.

6. When to Use Goals: The author acknowledges that goals can be useful in well-defined scenarios, like training for an event, but in complex situations, constraints are more effective.

7. Identity vs. Image: Westenberg emphasizes the importance of identity over image, suggesting that focusing on who we want to be (through constraints) can lead to more meaningful outcomes than simply aiming for achievements.

Overall, the article advocates for a mindset shift from chasing goals to setting personal limits that align with one’s values and aspirations.

The text discusses the balance between innovation and imitation in scientific papers. It highlights that sometimes groundbreaking research leads to many derivative works that do not advance the original idea significantly. For example, the 1943 McCulloch and Pitts paper on neural networks had the potential to connect different areas of AI but did not lead to much progress in that direction. Similarly, George Miller’s 7 +/- 2 paper on human memory was important for its methodology but mostly inspired minor follow-ups instead of deeper exploration.

The author notes that the structure of academic publishing often encourages this imitation, causing researchers to focus on small tweaks rather than the broader implications of pioneering ideas. Additionally, researchers may get stuck in their specific fields, missing opportunities for interdisciplinary connections. However, recent developments in AI show a mix of innovation and imitation, with many new papers providing significant insights alongside those that simply build on previous work.

A recent study shows that accreditation from the American College of Surgeons improves the quality of care in hospitals. This accreditation helps hospitals enhance their practices and patient outcomes. Overall, being accredited leads to better healthcare services for patients.

Why LLM Agents Are Not Ideal Pair Programmers

LLM agents, like GitHub Copilot, can code much faster than humans can think, which can lead to challenges in pair programming. While working with these AI agents can be exciting, it often feels similar to pairing with a skilled human programmer who works too quickly. This can cause frustration and disengagement, as the human partner struggles to keep up and may miss important context.

Suggestions for Improvement

To make the experience better, here are two main suggestions:

1. Shift to Asynchronous Workflows: Instead of trying to code together in real-time, break tasks into smaller pieces for the AI to handle independently. This allows for reviewing the work later, similar to how one would handle pull requests in GitHub.

2. Use Slower Interaction Modes: Switch from the rapid "Agent" mode to slower "Edit" or "Ask" modes. This way, programmers can maintain control and ensure quality by manually accepting changes.

Features to Enhance AI Pair Programming

To improve AI agents for pair programming, developers could:

• Allow users to set the speed of the agent’s output.
• Introduce pauses for clarification without disrupting the flow.
• Provide a user interface that aligns more with the tasks at hand.
• Design agents to express self-doubt and engage in conversation.
• Incorporate voice chat for a more natural interaction.

The goal is to make the AI's collaboration feel more like working with a human partner, fostering a better working relationship. Over time, as users adapt to these tools, improvements can be made to enhance their effectiveness in coding tasks.
