Summary of Reinforcement Learning from Human Feedback (RLHF) in Notebooks

This repository offers a guide for implementing Reinforcement Learning from Human Feedback (RLHF) for training large language models (LLMs) like GPT-2. The goal of RLHF is to align LLMs with user intentions by using a reward model instead of direct human feedback. The RLHF process involves three main steps:

1. Supervised Fine-Tuning (SFT): Fine-tune the LLM on a dataset of question-answer pairs.
2. Reward Model Training: Train a model to predict human rankings of the LLM's outputs.
3. Reinforcement Learning via Proximal Policy Optimization (PPO): Optimize the model to favor outputs that the reward model rates highly.

Example Scenario: To create a chatbot, one collects question-answer pairs, gets human ratings for these answers, and then applies the RLHF steps to improve the LLM.

In this repository, instead of a chatbot, the RLHF method is used to fine-tune GPT-2 to generate sentences that express positive sentiments using the stanfordnlp/sst2 dataset. The process involves three notebooks:

1. 1-SFT.ipynb: Fine-tunes GPT-2 to generate sentences similar to those in the dataset.
2. 2-RM Training.ipynb: Trains a reward model to assess sentiment.
3. 3-RLHF.ipynb: Uses PPO to refine sentence generation based on the reward model.

Getting Started:

• Prerequisites: Obtain a Hugging Face access token.
• Setup: Set the token as an environment variable.
• Running Notebooks: Execute the notebooks in order while following the instructions provided.

Upon completion, GPT-2 will be optimized to generate sentences that convey positive sentiments.

A new Tesla prototype has been spotted, leading to speculation that it could be a smaller version of the Model Y.

The rise of Artificial General Intelligence (AGI) is changing the economy and politics by blurring the lines between workers and owners. AGI can create economic value and is controlled by those who own its infrastructure, which may lead to increased inequality and a loss of democratic power. To address these challenges, we need to redefine our economic system, moving away from the traditional idea that human labor is the basis of economic participation. The paper suggests solutions like universal AI dividends, progressive taxes, and decentralized governance to ensure that the benefits of AGI are shared fairly. Action is needed now to prevent intelligence from becoming an exclusive form of wealth.

The Colombian navy recently seized its first unmanned narco-submarine, equipped with a Starlink antenna, off the Caribbean coast. Although no drugs were found, officials suspect it was a trial run by a cocaine trafficking cartel, specifically the Gulf Clan, which is Colombia's largest drug trafficking group. This type of vessel, designed to transport up to 1.5 tons of cocaine, represents a shift to more advanced, harder-to-detect methods of drug trafficking.

Colombia has been facing record highs in cocaine production, driven by increased global demand. The use of unmanned submarines is seen as a way for traffickers to evade detection and reduce risks associated with human crews, as they can operate with partial autonomy. In recent years, there have been other instances of drug traffickers using technology like Starlink for their operations. Colombian law imposes severe penalties for the construction and use of these semi-submersibles.

Summary of "Stop Killing Games and the Industry Response"

A new European Citizens' Initiative called "Stop Destroying Videogames" has gained over 1 million signatures, aiming to protect video games from being rendered unplayable by publishers. The initiative seeks to ensure that games sold in the EU remain functional after online services are discontinued, allowing players to continue enjoying single-player modes without publisher support.

The initiative was inspired by issues highlighted by a YouTuber, Accursed Farms, who pointed out that many modern games, like "The Crew," rely on publisher-managed servers, which can be shut down, making the games unplayable for consumers who thought they were purchasing them outright.

Opposition from the video game industry argues that discontinuing online services is necessary for business reasons and that creating private servers for older games is not a feasible solution. Critics of the industry believe this reasoning is flawed and that companies should be held accountable for ensuring that games remain playable.

The text also discusses responses from industry representatives, emphasizing the need for better consumer protection laws and modular game design that allows for continued access to purchased content. It highlights the importance of transparency in how games are marketed, suggesting that online-only games should be clearly labeled as subscriptions.

Overall, the article advocates for consumer rights in gaming, encouraging developers to provide ways for players to continue enjoying their games long after official support ends. It also expresses concerns about the potential for companies to circumvent new laws with "dark patterns," similar to issues seen with GDPR compliance.

The author expresses frustration with modern capitalism, particularly how technology and algorithms manipulate people's behavior in everyday interactions, like dating apps and ride-sharing services. They highlight the role of AI in extracting more value from users while making them feel less manipulated.

Summary of Simulated SPI RAM on RP2040

This project enables the RP2040 microcontroller to function like a serial SPI RAM, similar to a 23LC512. It supports three commands: READ, WRITE, and FAST READ. The RAM operates in sequential mode, and operations cannot exceed its memory limits. Only SPI mode is supported, with no support for DSPI/QSPI.

Maximum Speeds:

• READ: SYS clock / 10 (up to 12.5 MHz)
• READ (aligned): SYS clock / 8 (up to 15.6 MHz)
• FAST READ: SYS clock / 8 (up to 15.6 MHz)
• WRITE: SYS clock / 6 (up to 20.8 MHz)

An aligned READ starts at an address that is a multiple of 4, but its length doesn’t need to follow this rule.

Commands Explained:

1. READ (0x03): Follows with a 16-bit address. Data transfer starts immediately with no delay.
2. FAST READ (0x0B): Similar to READ but includes 8 delay cycles before data transfer.
3. WRITE (0x02): Follows with a 16-bit address and the data to write, starting immediately.

Integration Steps: To use this in your own project, copy four specific files into your project, include the sram.c file, and add necessary configurations in your CMakeLists.txt. Configure pins and possibly DMA channels in sram.h, then start the RAM with setup_simulated_sram().

How It Works: The system uses PIO and DMA to efficiently handle data transfer. The process involves waiting for a Chip Select (CS) signal, reading addresses, and transferring data while minimizing CPU overhead. Core1 of the RP2040 manages the operations and timing, ensuring data is available immediately after address processing.

Limitations:

• The duration for which CS must remain high between operations is not well-defined but is roughly estimated at 50 SYS clocks.
• Aborting operations before data transfer begins is not supported.

In 1947, General Mills offered the Atomic “Bomb” Ring as a promotion with its KiX cereal. It cost 15 cents plus a cereal box top and was popular due to the fascination with atomic energy at the time. The ring featured an adjustable gold-colored band with lightning designs and had an aluminum warhead on top, which included a removable red tailfin that served as a secret compartment for tiny messages.

Inside the warhead was a spinthariscope, which allowed users to see flashes of light in the dark, caused by radioactive particles interacting with the ring. Although the ring contained small amounts of Polonium-210, it was advertised as safe. However, any rings still around today no longer produce light due to the decay of the radioactive material.

A year ago, I created a community to help people find collaborators for side projects. After completing my first project, a digital course, I realized I needed a marketing partner but didn't know anyone. This led me to gather people with relevant skills in an Excel sheet and eventually create a Slack channel. Now, we have 400 members sharing projects and collaborating.

To improve our community, I partnered with a developer from our group and built a platform called "relentlessly.no," which currently has 50 users and 17 projects. We're working on enhancing features like notifications and user flows. I believe this community can be more valuable than traditional startup incubators because it connects people globally to create new startups from side projects.

The real value of this community is in the relationships formed, rather than just finding collaborators for specific projects. I've established many trustworthy connections that could lead to future ventures. I see this as my lifelong passion project, and I'm committed to supporting ethical entrepreneurship. I plan to invite people to include me in their funding rounds if they meet their cofounders through our platform, despite not having investment money myself.

The author describes how to create a simplified version of the Snake Game using minimal data structures. Here's a breakdown of the key points:

1. Data Structures: The game uses four integers to store all necessary information:

   • A uint32_t for the game map, representing the snake's body and the playing area.
   • A uint64_t for the snake's movement directions.
   • A uint32_t to keep track of the snake's head, tail, apple position, and length.
   • An int8_t for a loop counter.

2. Game Mechanics:

   • The game map is a 4x8 grid displayed using the curses library.
   • Key inputs (arrow keys) are used to change the snake's direction.
   • The snake grows when it eats an apple, and its position is updated accordingly.

3. Macros: The author employs many macros for bitwise operations to manage the game state efficiently. These macros help in setting, getting, and toggling bits for various game properties.

4. Game Loop:

   • The main loop initializes the game, processes user input, moves the snake, and updates the display.
   • Collision detection is handled to check if the snake hits the wall or itself.

5. Code Availability: The complete code is available on GitHub, and users can compile it using gcc with the curses library linked.

6. Final Note: The author emphasizes that the code is more of a joke or an exercise in minimalism rather than a model of good programming practices. The game is meant for fun and experimentation with bit manipulation.

Overall, the project showcases how to implement a simple game with significant constraints on data representation.

The text discusses the ongoing debate between two database providers, Planetscale and Neon, particularly highlighting Neon’s recent popularity due to its performance. The author references a quote from the book "Project Hail Mary," which emphasizes that different systems are designed for different purposes. While Planetscale and Neon each excel in their own areas, there is no one-size-fits-all solution in distributed systems. The author encourages engineers to recognize this and avoid negativity in discussions, as both platforms can be beneficial depending on the use case.

The Wind Knitting Factory is a unique knitting machine powered by wind, installed on a building's facade. Its large blades capture wind to drive the machine, which knits a long scarf that hangs down the side of the building. The knitting speed varies: it goes faster in strong winds and slower when it's calm.

As the scarf is knitted, it drops to a window, where it is transported inside for people to watch as it grows longer. Occasionally, the knitted fabric is collected and made into scarves, each labeled with the date and time the wind was used to create it.

This innovative project highlights how urban wind can be harnessed for production, blending public and private spaces in the city.

The "Stop Killing Games" movement has gained significant traction, collecting over a million signatures to become a European Citizens' Initiative. However, it faces opposition from Video Games Europe, a trade group for game publishers in the EU. They argue that ending online services is a complex decision that must remain an option for developers, as discontinuing support can be necessary for financial reasons. They also express concerns that enforcing private servers or single-player modes could increase costs and legal risks.

The author shares their journey of learning Haskell by building a Reverse Polish Notation (RPN) calculator, prompted by a friend's suggestion to explore functional programming. Initially familiar with imperative languages like Python and C, the author found Haskell's functional programming paradigm—where functions are mathematical abstractions and data is immutable—challenging but rewarding.

Key concepts learned included:

1. Recursive Types: Haskell allows defining natural numbers recursively, making the translation from mathematical definitions to code elegant.
2. Lambda Functions and Currying: Haskell's use of lambda functions and curried functions simplifies working with multiple arguments.
3. Merge Sort: Implementing merge sort in Haskell highlighted its clean and concise recursive structure.
4. Reverse Polish Notation (RPN): RPN simplifies mathematical expressions by eliminating the need for parentheses, allowing for straightforward stack-based evaluation.

The author initially struggled with implementing an RPN evaluator but sought guidance from Haskell expert Graham Hutton, who provided a more elegant solution. To enhance this solution, the author learned about monads—powerful structures in Haskell that manage context, error handling, and state, which are crucial for building parsers.

By creating a robust parser with monadic techniques, the author was able to handle complex input while keeping the code clean and readable. Reflecting on the experience, the author emphasizes the beauty and expressiveness of Haskell and the importance of learning from authoritative resources and mentors. The journey underscored the value of deep learning and sharing knowledge, encouraging others to embark on their own explorations.

Rene Turcios, known as the "hackathon king" of San Francisco, has participated in over 200 hackathons in just two years, despite not knowing how to code. Instead, he uses AI tools to create software, a practice called "vibe coding," which he embraced before it became widely recognized. Turcios has gained popularity in the hackathon community, winning prizes and building a reputation for quickly delivering projects that typically take much longer for traditional developers.

Before his hackathon success, Turcios had a unique background as a professional Yu-Gi-Oh! player and worked in various odd jobs after moving to San Francisco in 2019. Frustrated with traditional coding practices, he turned to hackathons to learn how to use AI for coding. His competitive spirit drives him to attend multiple events each week, and he has even started his own AI agents startup, relying solely on AI for coding tasks.

Turcios believes that anyone can create anything using AI, and he is now focusing on teaching others how to effectively use AI coding tools. His journey highlights the evolving landscape of coding and the increasing role of AI in software development.

Scientists are studying unusual types of lightning known as transient luminous events (TLEs), which occur high above thunderstorms. These include red sprites, green ghosts, and blue jets, and they are different from regular lightning. Red sprites, in particular, are bright red flashes that appear briefly above thunderstorms and are linked to powerful lightning strikes below.

The first red sprites were photographed in 1989, and since then, researchers have been trying to understand their causes and patterns. Recently, photographers captured a record number of red sprites over thunderstorms in South Asia, helping scientists connect these events to the lightning that triggers them.

A project called Spritacular, led by NASA, encourages volunteers to submit photos of TLEs, creating a database to help researchers identify trends and study these phenomena. Understanding TLEs is important not only for atmospheric science but also for predicting how climate change might affect thunderstorm activity and, consequently, TLE occurrences. Scientists believe that changes in climate could lead to more intense thunderstorms and stronger lightning, which could increase TLE activity. Overall, this field of study offers exciting insights into the connections between weather, electricity, and our atmosphere.

Summary of "Why the Simplest Desktop Agent Abstraction Wins"

Bytebot is a new approach to AI agents, focusing on simplicity and universality. Instead of building complex integrations with various tools and APIs, Bytebot operates by simulating a human worker's interaction with a computer using just a keyboard, mouse, and screen. This method allows it to work across all software and workflows designed for human use without needing custom setups.

The creators of Bytebot initially tried to develop a browser-based agent but faced numerous challenges due to the limitations of web technologies. They learned that complex systems often fail, while simple, scalable solutions yield better results. By designing Bytebot around human-computer interaction rather than current AI limitations, they aim to handle difficult tasks that don't fit neatly into structured APIs, such as using legacy software or managing multiple applications.

This approach provides several benefits:

• Universality: Works with any app or operating system.
• Fidelity: Can perform any action a human can.
• Composability: Actions can be combined and learned over time.
• Observability: Agent decisions can be traced through screenshots.
• Extensibility: Additional features can be added later.

On June 16, 2025, the Senate Finance Committee proposed new tax benefits for "qualified small business stock" (QSBS) after the House passed the "One Big Beautiful Bill Act." Currently, QSBS allows founders and investors in certain small companies to exclude up to 100% of gains from sales, with specific eligibility criteria.

The Senate proposal includes three main changes:

1. Tiered-Gain Exclusion: Introduces a tiered exclusion based on how long QSBS is held:

   • 50% exclusion for 3-4 years
   • 75% exclusion for 4-5 years
   • 100% exclusion for over 5 years

2. Increased Per-Issuer Cap: Raises the gain exclusion cap from $10 million to $15 million, with future adjustments for inflation.

3. Higher Gross Assets Threshold: Increases the gross asset limit for eligible companies from $50 million to $75 million, also adjusted for inflation.

These changes would make it easier for founders and investors to exit investments early without losing all tax benefits. However, the new rules would only apply to QSBS issued after the legislation is enacted, and existing investments would still follow the current rules. The proposal is seen as beneficial for startups and may impact financing decisions in the near future.

In the Salish Sea near British Columbia, researchers observed killer whales using bull kelp for grooming each other, a behavior called "allokelping." This is the first time any aquatic mammals have been seen using tools for cooperative grooming. The study, published in Current Biology, highlights the social behaviors of these endangered orcas, known for forming strong bonds and caring for their young.

Using drones, researchers documented a specific pod of 25 orcas over 12 days and identified 30 instances of allokelping. This behavior may help the whales with skin care, possibly by removing parasites or aiding temperature regulation. Unlike other tool-using animals, this grooming practice serves a social purpose, enhancing relationships between the whales.

Experts believe allokelping might be unique to southern resident killer whales, but similar behaviors could be discovered in other species. Understanding such cultural behaviors is crucial for conservation efforts, as it emphasizes the importance of preserving not just the physical traits of endangered species but also their cultural practices.

Summary of "Introducing tmux-rs" by Collin Richards

Collin Richards has been working on a personal project to rewrite the tmux terminal multiplexer from C to Rust. This project has reached a significant milestone: the entire codebase is now in Rust, although it still uses unsafe code. The original tmux code contained about 67,000 lines in C and has expanded to around 81,000 lines in Rust.

Key Points:

• Motivation: The rewrite is a hobby project, akin to gardening but with coding challenges. There's no specific reason for the change beyond personal interest.

• Initial Approach: Richards started using C2Rust, a tool that converts C code to Rust. However, the generated code was hard to maintain and excessively large, prompting him to manually translate the code.

• Development Process:

  • He built a solid understanding of tmux’s original build process using autotools.
  • He developed a new build system involving both Rust and C components.
  • The translation process involved translating one function at a time to ensure correctness.

• Challenges Encountered:

  • Various bugs were introduced during translation, often due to mismatched types or incorrect function declarations.
  • He found that raw pointers in Rust were necessary since Rust’s strict reference types couldn’t always be used directly.

• C Patterns in Rust:

  • The rewrite faced challenges related to C idioms, such as the use of goto, which were mapped to Rust constructs.
  • He had to work with intrusive data structures and reimplement a parser using the lalrpop library.

• Tools Used:

  • He relied on Vim for coding and tried an AI tool, Cursor, but found it didn’t significantly speed up his work.

• Conclusion: While the code is now fully in Rust, Richards acknowledges that it still has many bugs and isn't as reliable as he hoped. His next goal is to transition the codebase to safe Rust. He released version 0.0.1 of tmux-rs for others interested in Rust and tmux, inviting feedback and collaboration on GitHub.

Summary: The Right Way to Embed an LLM in a Group Chat

In group chats, adding an AI assistant can be useful but also potentially disruptive. People often prefer using separate apps like ChatGPT for questions, but integrating AI can save time when it helps with tasks like creating polls for group decisions. For instance, in the travel planning app TripJam, the AI can suggest restaurants and make polls directly in the chat.

The main challenge is that in a group chat, users usually address each other, not the AI, making it important for the AI to be helpful yet unobtrusive. The AI should perform useful tasks like summarizing locations or managing itineraries without interrupting the conversation.

To enhance the AI's effectiveness, it should have access to various tools, such as adding locations or creating polls, and it should be able to understand user queries efficiently. Right now, it only responds when directly asked, but future updates may allow it to infer when assistance is needed, while minimizing interruptions.

Privacy is a priority, and while the AI uses external models, there are plans for better privacy options in the future. Overall, the goal is to make group chats more convenient and interactive with AI assistance while respecting user privacy and minimizing disruption.

Summary of Compression Dictionary Transport

Compression Dictionary Transport is an experimental technology designed to reduce the size of HTTP responses by using a shared compression dictionary. This method helps decrease bandwidth usage and speeds up page loading times.

Key Points:

1. Purpose: It utilizes a shared dictionary to identify and reference repeated strings in data, allowing for more efficient compression.
2. How It Works: Instead of sending the same string multiple times, the system sends a reference to a single copy of the string. For instance, in JavaScript, repeated phrases can be replaced with shorter references.
3. Advantages: This technology can achieve greater compression than standard methods by using a custom dictionary tailored to specific resources, reducing download sizes significantly.
4. Dictionary Sources: A dictionary can be formed from previous versions of a file or from commonly used strings. This helps capture only the differences (delta compression) between versions.
5. Implementation:
   • The server indicates which resources can use a specific dictionary through headers.
   • Browsers can download the dictionary during idle time.
   • The compression responses must include specific headers to work correctly.
6. Security Restrictions: There are security measures in place to prevent abuse, such as requiring dictionaries to be from the same origin and following CORS rules.

Conclusion: Compression Dictionary Transport represents a promising way to improve web performance by optimizing how data is compressed and transferred, but it is still experimental and should be used carefully, with attention to browser compatibility and security considerations.

Overall, the research suggests that having a pet, particularly dogs or cats, could be a positive factor in maintaining cognitive function as people age. Future policies might consider supporting pet ownership among older adults to promote healthy aging.

The blog post discusses SIMD (Single Instruction, Multiple Data) functions, which allow a function to process multiple data points simultaneously, enhancing performance. Here are the key points:

1. Definition of SIMD Functions: SIMD functions process multiple inputs at once. For example, a standard sine function takes one value, while a vector version can take an array of values.

2. Why Use Vector Functions?: Vector functions improve performance by enabling the compiler to automatically vectorize loops, allowing for parallel processing of data.

3. Declaring Vector Functions: There are methods to declare vector functions using compiler-specific attributes or OpenMP pragmas. This informs the compiler about available vector implementations.

4. Parameter Types: Parameters in vector functions can be categorized as variable, uniform, or linear, which affects how the function operates and its efficiency.

5. Limitations and Challenges:

   • Limited Compiler Support: Not all compilers fully support SIMD functions; some may generate inefficient implementations.
   • Usability Issues: Compilers may not optimize vector functions as efficiently as expected, particularly if the function calls prevent inlining.
   • Overwriting Compiler Implementations: To provide custom implementations for better performance, developers may need to work with compiler internals and naming conventions.

6. Compiler Quirks: Some compilers might not generate vector calls efficiently or at all under certain conditions, complicating the use of SIMD.

7. Conclusion: While SIMD functions offer significant performance benefits, getting them to work effectively across different compilers and environments can be challenging. Proper understanding and careful implementation are required for optimal performance.

The post also invites readers to reach out for discussions on performance issues or training on vectorization.

If you're working in tech and want to leave for a more meaningful career, you have several options. Your reasons for wanting to change may vary, such as feeling unfulfilled by the tech industry or wanting to make a positive impact. Here are some paths to consider:

1. Public Institutions: Working in the public sector can offer a more relaxed environment and meaningful projects that affect many people. However, be cautious of consultancy firms that may compromise the quality of work.

2. Tech Cooperatives: In a tech co-op, you and your coworkers share ownership and decision-making power. This offers freedom but also comes with more responsibility. You can start small, often focusing on consultancy work.

3. Tech NGOs: Many non-profit organizations need tech talent to support their missions in areas like environmentalism, human rights, and education. Networking and targeted outreach can help you find these opportunities.

4. Unions or Political Parties: If you want to improve conditions within the tech industry, consider working in the tech department of a union or political party. These organizations often require tech support for their operations.

5. Teaching and Mentoring: If you enjoy sharing knowledge, consider teaching programming or design at schools, universities, or online platforms. There’s a strong demand for educational roles in tech.

6. Techno-Political Hustler: This is a newer concept where individuals engage in various projects and organizations driven by social, political, or ethical motivations. It involves connecting people and resources but requires a broad skill set and network.

Ultimately, the process of finding a fulfilling career is personal and requires self-exploration. It's never too late to seek a path that aligns with your values and interests.

Summary of GREMLLM

GREMLLM is an upgraded utility class designed to enhance your coding experience with dynamic behavior. It allows objects to implement methods and properties on-the-fly using LLM reasoning.

Installation: You can install GREMLLM using the command:

pip install gremllm

Usage: To use GREMLLM, you need to specify what kind of object it is. For example:

from gremllm import Gremllm

counter = Gremllm('counter')
counter.value = 5
counter.increment()
print(counter.value)  # Outputs 6

Key Features:

• Dynamic Behavior: Objects can change their methods and properties dynamically.
• Wet Mode: Allows method calls to return living GREMLLM objects for continuous chaining.
• Verbose Mode: Displays the generated code for better understanding.
• Multi-Model Support: Compatible with various models like OpenAI, Claude, and local models.
• Inheritance: Child objects inherit settings like wet and verbose modes.
• Smart Error Handling: Provides fallbacks when issues occur.

Configuration: You can configure your preferred LLM using:

llm keys set openai  # For OpenAI

Other models can also be set similarly.

Examples:

1. Counter Example: Basic operations like incrementing a value.
2. Shopping Cart Example: Managing items in a cart and calculating totals.

Wet Mode: In this mode, methods return GREMLLM objects, allowing for infinite interactions:

wet_counter = Gremllm('counter', wet=True)
result = wet_counter.increment()  # Returns a living object

Verbose Mode: You can enable this mode to see the code generated during execution, helping with debugging.

Overall, GREMLLM provides a unique and flexible way to work with objects in your code, making interactions more dynamic and engaging.
