Summary:

The text introduces clean, a new formal verification domain-specific language (DSL) for zero-knowledge (ZK) circuits, developed using Lean4. The goal of clean is to help define ZK circuits, specify their properties, and formally prove their correctness. This is part of the zkEVM Formal Verification Project aimed at enhancing the reliability of ZK circuits.

Key Objectives:

• Create an embedded DSL for ZK circuits in Lean4 to enable formal reasoning.
• Co-locate circuit definitions with their specifications and proofs to develop reusable circuit components.
• Focus on AIR arithmetization and include a table lookup capability.

Formal Verification Process:

1. Define supported operations (primitives) for circuits.
2. Establish the meaning of these primitives (semantics).
3. Identify properties to formally prove for each circuit.

Circuits consist of variables and constraints, with the aim of ensuring that a prover can demonstrate knowledge of a witness that satisfies these constraints. Key properties to be proven include:

• Soundness: If a witness satisfies the constraints, then certain specifications must hold.
• Completeness: For any valid input, a witness can always be found.

DSL Design: The DSL supports four basic operations for circuit definition:

• Witness: Introduce variables and define how to generate them.
• Assert: Add constraints to the circuit.
• Lookup: Define relationships between variables and tables.
• Subcircuit: Include smaller circuits within larger ones for composability.

Verification Framework: The framework uses a FormalCircuit structure to package circuit definitions along with proofs of soundness and completeness. It allows for the modular verification of circuits, enabling the reuse of verified components.

Example Implementation: An 8-bit addition circuit is provided as an example, which computes the sum of two bytes and handles carry operations. The circuit is defined with input and output structures, assumptions, specifications, and soundness/completeness proofs.

Future Work: The project aims to expand its library of reusable circuits, define common hash functions, and create a minimally verified virtual machine for RISC-V. The entire project is open-source and available on GitHub.

Sabine Hossenfelder expresses frustration with large language models (LLMs) like GPT, Grok, and Gemini, which she uses daily. She finds that these models often make up sources, links, and quotes that don't exist, leading to inaccuracies in their responses. Although there has been some improvement over the past two years, she estimates that only 50-60% of references provided by these models are legitimate.

Hossenfelder notes that Grok often fails to include references, while Gemini is even less reliable, frequently directing her to search for information herself. She also mentions that LLMs make frequent errors in estimating numerical values but can help with unit conversions and collecting constants.

She highlights a specific instance where GPT incorrectly dated a paper she uploaded, further illustrating her concerns about the models' reliability. Hossenfelder believes that while some hope knowledge graphs will solve LLM issues, they won't, as logical consistency doesn't guarantee truth. She predicts that companies investing in LLMs might face significant losses if a better AI model emerges, which could impact the stock market negatively.

A Japanese man who was paralyzed can now stand on his own after receiving an injection of reprogrammed stem cells for his spinal cord injury. He was one of four participants in a pioneering trial led by Hideyuki Okano at Keio University. Another participant regained some arm and leg movement, while the other two saw very little improvement. The trial is still in the early stages and has not been peer-reviewed, but researchers believe the treatment is safe.

Induced pluripotent stem cells (iPS cells) were used in this study, created by reverting adult cells to an embryonic state. Two million of these cells were injected into each patient's injury site to potentially develop into nerve cells. All participants had severe spinal injuries and were given immune-suppressing drugs to prevent rejection of the cells.

At the one-year follow-up, no serious side effects were reported, and one participant is even training to walk. Larger trials are needed to confirm whether the observed improvements were due to the treatment or natural recovery.

The report by Jeffrey Knockel and colleagues analyzes Amazon's censorship practices on its US website, particularly regarding the restriction of certain products, especially books, from being shipped to specific regions. Here are the key points:

Summary

Issue with Terraform Providers: Sometimes, Terraform providers change attributes in ways that can cause problems. For instance, the Docker provider converts the "image" attribute into a SHA digest. This can lead to Terraform wanting to recreate resources unnecessarily, causing downtime.

Current Solution: One common fix is to ignore changes to the "image" attribute in the resource configuration. However, this can lead to issues if you later change the image version, as Terraform won't recognize the update and may not apply the intended changes.

Alternative Approach: A better method is to use a null_resource that tracks changes to the image. When the image changes, this null_resource triggers a re-creation of the Docker container, while the original resource ignores the change. Here’s how you can set it up:

1. Define the image as a local variable.
2. Create a null_resource that triggers on the image change.
3. In the Docker container resource, ignore image changes but include the null_resource in the replace_triggered_by attribute.

This way, you can manage updates without unnecessary downtime, although this method should be used sparingly.

Improvements: The author suggests that ideally, the Docker provider should be improved to handle image name changes better. A pull request could have been made to address this, but sometimes time constraints prevent such fixes.

New research suggests that future chips may need alternatives to copper for better conductivity. A thin film made of polycrystalline niobium phosphide, just a few atoms thick, shows improved surface conductivity, making it a potentially better overall conductor.

The search engine's crawler has been slow, often taking several days to finish crawling the last few websites. Recently, changes reduced memory usage by 80%, allowing more crawling tasks to be completed quickly. Now, 99.9% of crawling is done in 4 days, while the remaining 0.1% takes a week. This delay is due to some websites being very large and restrictions on how many concurrent tasks can be run for the same domain to avoid issues with anti-crawler software.

Initially, the crawler used a random order for crawling, which sometimes caused larger academic sites to start late. To improve this, the crawling tasks were sorted by the number of subdomains, but this led to too many requests hitting blog hosts at once. To fix this, a delay was added to stagger the requests, and the sorting criteria were adjusted to better mix the domains.

The new approach seems to prioritize slower crawling tasks more effectively, although it won't completely solve the problem. Future improvements could involve tracking how long previous crawls took, but this information isn't currently available.

The Alan Turing Institute (ATI), the UK's national AI institute, is facing a crisis despite receiving £100 million in funding in 2024. The institute is planning to lay off staff and cut research projects due to internal discontent and criticism of its effectiveness. Critics argue that the ATI has failed to keep pace with advancements in AI, particularly in generative AI, and that it has not addressed key areas like large language models (LLMs) in its strategies.

Originally established in 2014 amid the "big data" hype, the ATI has struggled with vague goals and a lack of cohesive governance. It operates more like a collection of universities rather than a unified research institution, leading to conflicts of interest and limited collaboration among academics. Many researchers view the ATI as a way for universities to profit from public funds rather than as a driver of innovation.

The ATI's focus has shifted towards commercial projects and ethics rather than cutting-edge AI research, which has alienated many top researchers. Its failure to adapt to significant developments in AI, such as the rise of generative models, has resulted in a perception of irrelevance. A recent review by UK Research and Innovation highlighted the need for a fundamental change in governance.

While some programs within the ATI, particularly those related to defense and security, have shown success, the overall approach of the institute reflects broader issues in the UK's technology strategy, such as shifting priorities and reliance on universities for research. The ATI's experience serves as a cautionary tale about institutional failure and the challenges of effectively managing public research initiatives.

Summary:

Creating self-serve access to internal systems can be beneficial, but it's not always the right solution. It's helpful when tasks are simple, but for complex tasks, a self-serve UI may not actually simplify the process and can introduce risks.

Key points include:

1. Complex Tasks Require Engineering: Just because a task seems trivial doesn't mean it doesn't need engineering. Complex changes often require significant background work that a self-serve UI can't address.

2. Practical Downsides: Self-serve UIs can complicate debugging, lack revision history, and make testing difficult, as they do not integrate well with traditional code management practices.

3. Decision-Making Limitations: Computers lack the context to make informed decisions about project goals, customer needs, and company culture. Human experience is crucial for understanding implications of engineering decisions.

4. Rigidity and False Security: Self-serve UIs can make systems more rigid, limiting what users can do and creating a false sense of security that tasks are simpler than they are.

5. Potential for Mistakes: Easy interfaces can lead to errors, as users may misclick or not fully understand the consequences of their actions.

6. Conclusion: While self-serve UIs can reduce tedious work, they shouldn't be used to simplify complex tasks without a thorough understanding of the underlying challenges. It’s often better to address the root issues in the system rather than relying solely on UI solutions. If a self-serve tool is developed, it should be specific and adaptable to various needs.

Summary of "The Black Swan" Documentary

"The Black Swan" is a documentary directed by Mads Brügger, featuring Amira Smajic, a former master criminal turned informant. Over six months in a rented office in Copenhagen, Smajic secretly filmed corrupt conversations with various individuals involved in financial crimes, including lawyers and gang members. The documentary reveals Denmark's hidden corruption and challenges the country's self-image as a virtuous society.

Since its airing in 2025, "The Black Swan" has shocked Denmark, leading to criminal charges and the introduction of new money-laundering laws. About half of the Danish population has seen the series, sparking discussions about trust in public institutions and the reality of corruption in a country that prides itself on integrity.

Smajic, known as the "Ice Queen," had previously facilitated money laundering for biker gangs. Initially seeking redemption, she later revealed her duplicity, as she was still engaging in criminal activities during filming. The documentary raises ethical questions about journalistic practices, as Smajic's role as a police informant was kept secret.

Brügger's provocative style often involves setting traps for his subjects, and this documentary is no exception. It showcases the ease with which individuals exploit the system, blurring the lines between crime and legality. Ultimately, "The Black Swan" exposes the underlying corruption within Danish society, prompting a reevaluation of trust and morality among its citizens.

Scientists have discovered a new molecule called “berkelocene,” which is the first organometallic molecule containing the heavy element berkelium. This molecule was created from a tiny amount of berkelium-249 in specialized facilities that handle radioactive materials. The discovery challenges previous beliefs about how elements after uranium behave chemically.

Berkelium, discovered in 1949 by Glenn Seaborg, is part of a group of elements known as actinides. While organometallic molecules are common for earlier actinides like uranium, they are rare for later actinides like berkelium. The research team, led by experts at Lawrence Berkeley National Laboratory, found that berkelocene has a unique structure with berkelium bonded to carbon, which helps scientists understand the behavior of actinides better.

Studying berkelium is difficult due to its radioactivity and sensitivity to air. The researchers designed new equipment to safely conduct experiments with this element. Their findings revealed that berkelium can exist in a +4 oxidation state, which is different from what was expected based on traditional models.

This research may help improve understanding of actinides, which is important for dealing with nuclear waste and other related challenges.

The author shares a challenging experience while working on Google Docs, where they encountered a severe bug that caused crashes without a clear cause. This bug, which appeared in a specific version of Chrome, was particularly difficult to debug because it was non-deterministic, meaning it didn’t happen consistently.

Initially, the author investigated logs and tried to replicate the bug through various methods but had no luck. They eventually created a large document and used a script to bold and unbold text, which helped them reproduce the crash. After extensive debugging alongside a coworker over two days, they discovered the issue stemmed from a problem in the bookkeeping code that involved a faulty implementation of the Math.abs() function, which incorrectly returned negative values.

The root cause was traced back to a recent optimization in the V8 engine (Chrome's JavaScript engine), where a mistake in the code had transformed Math.abs() into an identity function, only manifesting under specific conditions. The team implemented a temporary fix while documenting the issue for future reference. Ultimately, the experience highlighted the unpredictable nature of debugging and the complexities involved in software development, with no clear moral or lesson to be gleaned.

Summary of Sharding pgvector

Overview pgvector is a tool for handling embeddings in Postgres, but as data scales (around a million arrays), indexing becomes slow. A solution to manage large datasets is sharding, which involves splitting the vector index across multiple machines to improve search speed and recall.

Index Types pgvector has two index types:

1. HNSW: Fast searching (O(log(n))) but slow to build.
2. IVFFlat: Quick to build but slower to search (O(sqrt(n))). It organizes vectors into groups based on centroids.

Sharding Approach Sharding involves splitting data into parts, similar to how IVFFlat groups vectors. This allows parts to be distributed across multiple machines, enabling faster searches. The process starts by calculating centroids using K-means clustering.

Testing Sharding The team tested the concept using the Cohere/wikipedia dataset, which encodes English Wikipedia articles into 768-dimensional embeddings. The sharding function selects shards based on the distance to centroids.

Results Tests showed good results, with high recall rates for similar queries. Using multiple shards improved the number of successful queries significantly.

Future Steps The project plans to explore additional distance algorithms and implement SIMD instructions for faster computations. PgDog is open-source and seeking partners for development.

Reinforcement Learning (RL) is a type of machine learning where an agent learns to make decisions by interacting with an environment to maximize rewards. Key concepts include:

1. Agent and Environment: The agent takes actions in an environment to receive rewards. The goal is to learn a strategy that maximizes cumulative rewards over time.

2. Key Terms:

   • State (s): A specific situation in the environment.
   • Action (a): The choices available to the agent.
   • Reward (r): Feedback from the environment after an action is taken.
   • Policy (π): A strategy that defines the action to take in each state.
   • Value Function (V): A measure of how good it is to be in a given state under a specific policy.

3. Markov Decision Processes (MDPs): Most RL problems can be framed as MDPs, where future states depend only on the current state and action.

4. Common Algorithms:

   • Dynamic Programming: Used when the model of the environment is known.
   • Monte-Carlo Methods: Learn from complete episodes of experience without needing the model.
   • Temporal-Difference Learning: Learns from incomplete episodes, updating estimates based on other learned values.
   • SARSA and Q-Learning: Popular TD learning methods; SARSA is on-policy, while Q-learning is off-policy.
   • Deep Q-Networks (DQN): Combines Q-learning with deep learning to handle large state-action spaces.

5. Policy Gradient Methods: Directly learn the policy rather than the value functions, useful for complex action spaces.

6. Challenges:

   • Exploration vs. Exploitation: Balancing between trying new actions and optimizing known rewards.
   • Deadly Triad: Instability that arises when combining off-policy learning, nonlinear function approximation, and bootstrapping.

7. Case Study - AlphaGo Zero: A landmark example of RL where the AI defeated top human players in Go, using self-play and reinforcement learning without human data.

Overall, reinforcement learning is a powerful framework for developing intelligent systems capable of learning optimal behaviors through trial and error in various environments.

Summary of How Trump is Following Project 2025’s Roadmap to Defund Science

In recent months, President Donald Trump has taken significant actions that impact the U.S. research community, many of which were planned in advance as part of "Project 2025," a detailed policy guide released by the Heritage Foundation. This blueprint outlines aggressive proposals aimed at conservative policymakers, including drastic cuts to science funding and the dismantling of diversity programs.

Despite Trump initially claiming he was unaware of Project 2025 during his 2024 campaign, his administration has enacted many of its recommendations. Over half of Trump’s executive orders align with Project 2025, which seeks to reduce federal oversight and funding for scientific initiatives. Major actions already taken include:

1. Ending Diversity Programs: Trump has signed an executive order that terminates diversity, equity, and inclusion (DEI) programs, affecting key agencies like the National Science Foundation (NSF) and the National Institutes of Health (NIH).

2. Defunding Climate Science: The Trump administration is working to withdraw from the Paris climate agreement and roll back environmental regulations.

3. Cutting University Funding: The NIH attempted to reduce the indirect costs universities receive for research, although a federal judge has temporarily halted this policy.

4. Reducing Government Workforce: There have been mass layoffs in federal agencies, including NASA and NIH, as part of efforts to downsize the government.

Looking ahead, many recommendations from Project 2025 remain unimplemented, but there are indications that further cuts to scientific research, including fetal-tissue research, may be on the way. Overall, Trump's actions reflect a departure from traditional science funding and support, aligning closely with the radical agenda laid out in Project 2025.

The author, a beginner in Rust, explores the concept of dynamic dispatch and trait objects through a coding example involving a struct called CloningLab that uses a vector of Mammal trait objects. Initially, the author defines the Mammal trait with methods for walk and run, and implements it for a Cat struct. This setup works well until the author tries to add another trait, Clone, to the Mammal bounds, which results in a compilation error.

The author is surprised by this limitation, as they expected it to work similarly to multiple inheritance in C++. They explain that Rust uses vtables (tables of function pointers) for dynamic dispatch, which adds an indirection layer and differs from C++'s approach. Rust's design encourages monomorphism, which is seen as a beneficial trade-off.

The author discusses how multiple bounds could be handled in C++ and suggests a potential implementation in Rust using trait inheritance to create a single vtable, reducing redundancy. However, they highlight a limitation: you cannot convert a trait object of a combined trait type (like CloneMammal) to a more specific trait type (like Clone). This is due to the compiler's inability to determine the correct vtable for the specific trait object at runtime.

In conclusion, the author finds this exploration helpful for understanding trait objects in Rust, despite the restriction not being a major issue in practice.
