Summary: Building a 30 Petabyte Data Storage Cluster

The Standard Intelligence Team built a 30 petabyte storage cluster in San Francisco to manage 90 million hours of video data for training machine learning models. This setup was necessary because training with video data requires significantly more storage than text data. Instead of spending $12 million annually on cloud storage with AWS, they opted for a local colocation center, reducing costs to about $354,000 per year.

Key Reasons for Local Storage:

• Machine learning training data can tolerate some data corruption, so high reliability is not needed.
• Most businesses use less storage, making cloud solutions expensive relative to their needs.

Cost Breakdown:

• Recurring Costs: $17,500/month for internet and electricity.
• One-Time Costs: Approximately $426,500 for hardware setup (hard drives, storage infrastructure, compute nodes, and installation).

Comparison of Costs:

• AWS would cost about $1,130,000/month.
• Cloudflare would cost around $270,000/month.
• Their local setup costs $29,500/month, making it significantly cheaper.

Setup Process: The team organized a "Storage Stacking Saturday" to quickly assemble the hardware with help from friends. They used simple software to manage data storage, avoiding complex systems that could complicate debugging.

Lessons Learned:

• Proximity to the datacenter was beneficial for maintenance.
• Simplicity in software design helped avoid debugging headaches.
• Proper planning and management of networking were crucial.

Recommendations for Similar Projects:

• Use high-density storage solutions to save space and effort.
• Invest in quality networking equipment to avoid bottlenecks.
• Consider building a similar setup with specific hardware and configuration guidelines provided in the detailed write-up.

The project allowed the team to gather extensive data at a low cost, positioning them competitively against larger labs with substantial funding. They are also looking for new talent to join their research efforts in machine learning.

This chapter introduces natural transformations, which are fundamental in category theory and serve as morphisms between functors. Understanding them is essential for defining concepts like category equality.

Key Concepts:

1. Natural Transformations: These are ways to map between functors, which are themselves mappings between categories. They are crucial for establishing equality between categories.

2. Equivalent Categories: Categories can be considered equivalent if they share the same structure, despite not being isomorphic, meaning they can have different objects but similar relationships between those objects.

3. Isomorphism Invariance: In category theory, isomorphisms are seen as equality. When two objects are isomorphic, they share properties, allowing us to treat them as equal for many purposes.

4. Morphisms vs. Objects: Traditional views in mathematics often focus on objects, but the chapter argues that the relationships (morphisms) between objects are more significant for understanding categories.

5. Natural Transformations in Programming: These can be related to polymorphic functions in programming, where a function can operate on various types in a consistent way.

6. Commutative Diagrams: Natural transformations can be visualized using diagrams that show how morphisms interact, ensuring that certain relationships hold (commute) across transformations.

7. Composition of Natural Transformations: They can be composed both horizontally and vertically, allowing for complex interactions between functors.

8. 2-Categories: The chapter hints at an advanced concept where categories themselves can have morphisms between their morphisms (natural transformations), leading to the idea of "2-categories".

In summary, natural transformations are a crucial concept in category theory that help define relationships between functors and establish equality between categories. They have practical implications in programming and are essential for understanding more complex category structures.

The text discusses the growing divide between designers and developers in web development. Initially, designers and developers worked together seamlessly, but as the web evolved, their roles became more separated. Designers focused on visual aspects using tools like Figma, while developers handled the coding side with complex frameworks. This separation has led to a frustrating "hand-off" process, where communication is hindered by different languages and tools.

Despite efforts to improve collaboration, the core issue remains: the split between designers and developers creates friction and limits creativity. Designers now often lack the ability to implement their functional designs, as they are constrained by their tools and processes.

Nordcraft was created to address these challenges by developing a platform that integrates design and development. It allows for more collaboration and flexibility, enabling teams to leverage each other's strengths without rigid roles. The goal is to foster a more creative and efficient environment for web design and development.

Summary of "How to Avoid Fighting Rust Borrow Checker"

Key Concepts in Rust:

1. Tree-Shaped Ownership: Each object in Rust can have one parent and many children, forming a tree structure.
2. Mutable Borrow Exclusiveness: Only one mutable reference to an object can exist at a time; if one exists, no other references (mutable or immutable) can exist.
3. Contagious Borrowing: Borrowing an object can affect its parent and other objects in its hierarchy. For example, borrowing one wheel of a car implies borrowing the whole car.

Reference Shapes:

• Tree-Shaped References: Easy to manage in Rust.
• Shared References: Can complicate ownership and borrowing rules.
  • For immutable shared objects, use lifetime annotations or reference counting (Rc/Arc).
  • Mutable shared objects can cause issues due to borrow-checking rules.

Challenges with the Borrow Checker:

• Contagious Borrow: Borrowing a child can implicitly borrow its parent, complicating mutable operations.
• Cycles: Circular references can lead to borrowing issues.

Solutions for Borrow-Checker Issues:

1. Data-Oriented Design: Focus on data structures to minimize unnecessary getters/setters and avoid contagious borrows.
2. Use IDs/Handles: Replace direct borrowing with identifiers to manage references and avoid borrowing issues.
3. Defer Mutation: Use commands to schedule changes rather than immediate mutations.
4. Avoid Mutation: Opt for immutable data or recreate data structures instead of mutating them.
5. Handle Circular References: Use weak references to break cycles, especially in callbacks.

Interior Mutability:

• Use types like RefCell, Cell, or Mutex to allow changes to data while maintaining the borrow checker rules.

General Guidelines:

• Minimize the scope of borrows and keep them as short-lived as possible.
• Consider using data structures that avoid unnecessary references, like arrays or maps.
• Understand that while Rust provides safety benefits, it can require more complex design patterns to manage ownership and borrowing effectively.

Conclusion: Rust’s borrow checker enhances safety but can lead to complications in mutable data management. Employing strategies like data-oriented design, using handles instead of direct borrowing, and managing mutability carefully will help developers work more effectively within Rust’s ownership model.

Summary of "The Business of Sportsbooks is Built on Losers"

Sportsbooks, like DraftKings and FanDuel, operate in a low-margin environment and rely on casual bettors, often referred to as "losers." Here are the key points:

1. Business Model: Sportsbooks set odds for sports events and take bets from users. They make money primarily through a small margin called "vig" built into the odds. The average casual bettor loses about $100 per year, while skilled bettors (sharps) can win large amounts, which can threaten the sportsbook's profits.

2. Targeting Casual Bettors: Sportsbooks focus on attracting inexperienced bettors who are more likely to place bets on their favorite teams. Only about 3% of bettors make a profit.

3. Costs and Profitability: Sportsbooks face high costs, including state taxes (up to 51% in some states), promotions, and advertising, which significantly cut into their profits. They spend heavily on marketing to acquire new customers, often around $300 per user.

4. Restricting Skilled Bettors: To protect their profits, sportsbooks often restrict or ban skilled bettors who can exploit their odds. This is legal, as businesses can refuse service to customers unless it involves discrimination against protected classes.

5. Parlays as a Revenue Source: Sportsbooks encourage bettors to place complex bets called parlays, which have a higher vig and drive up profits. They use strategies to keep users engaged and betting frequently.

In conclusion, sportsbooks thrive by attracting casual bettors while limiting the impact of skilled gamblers, all within a tough regulatory and financial landscape.

Summary of "Mind the encryptionroot: How to save your data when ZFS loses its mind"

This article is a personal account of the author's experience with ZFS (Zettabyte File System) and its native encryption, where they almost lost 8.5 TiB of data due to mistakes made during routine operations. The author shares their journey to understand the issues, debug the situation, and ultimately recover the data.

Key Points:

1. Background: The author had two ZFS pools (old and new) for data management, with the new pool using native encryption from the start. The old pool was later upgraded to encryption, which led to complications.

2. The Issue: Changing the encryption key for the old pool without properly managing snapshots led to an undecryptable dataset. The author realized too late that the backups were no longer valid because the encryption key changes were not reflected in the backups.

3. Lessons Learned:

   • Continuously test backups to catch issues early.
   • Perform destructive changes only after verifying all steps are in order.
   • Always send a snapshot of the encryption root after changing encryption keys.
   • Create bookmarks before deleting snapshots.

4. Debugging Process: The author explored how ZFS works, including its copy-on-write filesystem, snapshots, and the mechanics of native encryption. They formed a hypothesis about what went wrong and created a test environment to reproduce the issue.

5. Data Recovery: The recovery process was complex, involving creating a modified version of ZFS to manually create bookmarks and send the necessary snapshots to restore access to the encrypted datasets.

6. Conclusion: The author successfully recovered their data and emphasizes the importance of understanding ZFS's encryption features and practices. They advise caution when using native encryption until improvements are made, suggesting the use of block-level encryption instead for most users.

This account serves as a cautionary tale for those using ZFS encryption, highlighting potential pitfalls and the importance of careful data management.

Chronic inflammation is now recognized as a stronger predictor of heart disease than cholesterol, according to new recommendations from the American College of Cardiology (ACC). They suggest that everyone should have their inflammation levels, specifically high-sensitivity C-reactive protein (hs-CRP), measured through a blood test. This shift is significant because it highlights inflammation as a standard modifiable risk factor for heart disease.

Key findings include:

• High levels of inflammation (hs-CRP) correlate more closely with heart disease risk than cholesterol levels, especially in patients already on cholesterol-lowering statins or those without traditional risk factors.
• Traditional risk factors still matter, but inflammation remains a crucial factor.
• Effective ways to lower inflammation include using certain medications like statins and colchicine, as well as lifestyle changes such as a healthy diet, regular exercise, quitting smoking, and maintaining a healthy weight.
• Not all anti-inflammatory drugs work; some have shown no benefit in major trials.

For hs-CRP levels:

• Ideal levels are below 1 mg/L, while levels above 3 mg/L indicate high risk.
• Other inflammation markers have been evaluated, but hs-CRP is the most effective for predicting cardiovascular risk.

The ACC now recommends routine hs-CRP testing for everyone, emphasizing the importance of addressing inflammation as a separate risk factor from cholesterol.

Summary of Virtual Memory Basics

1. Purpose of Main Memory: Computers use main memory (RAM) for fast data access, as it is quicker than disk storage. The CPU works with RAM due to its speed, even though it is volatile (data is lost when power is off).

2. Memory Allocation: The operating system allocates memory to multiple processes, ensuring they don't interfere. A simple method is to assign contiguous blocks of memory, but this can lead to external fragmentation when free memory isn't contiguous.

3. External Fragmentation: This occurs when total free memory is sufficient, but not in one continuous block. This can prevent the system from running more processes efficiently.

4. Paging: To combat fragmentation, operating systems use paging, which divides memory into fixed-size blocks (frames). Processes access a virtual memory space that appears contiguous, even if the physical memory is not.

5. Demand Paging: Not all parts of a program need to be loaded at once. Demand paging loads only the necessary pages into memory, which helps save space and manage large programs more efficiently.

6. Memory Layout: A process’s virtual memory is divided into segments like the stack (for function calls), heap (for dynamic memory), and code segment (for executable code). Each has specific functions and growth directions.

7. Stack vs. Heap Allocation: The stack grows downwards for function calls and local variables, while the heap grows upwards for dynamic memory allocation. Stack allocation is faster but limited to known sizes at compile time, whereas heap allocation is more flexible but slower and requires larger management overhead.

8. Memory Mapping: This allows files and memory to be mapped directly into the process's address space. Memory mappings can be private (copy-on-write) or shared between processes.

9. System Calls: Linux uses system calls like malloc for heap memory management and mmap for memory mapping, allowing efficient memory allocation and management tailored to program needs.

Understanding these concepts helps in grasping how operating systems manage memory and optimize performance for various applications.

Quality in software is essential, but there’s no consensus on its definition or who decides it. Many leaders mistakenly equate quality with metrics like KPIs, but true quality is about meeting user expectations. Companies like Linear focus on quality as a brand value, while at Stripe, quality was a major priority, achieving 99.999% uptime.

Quality should not be a slogan or a scorecard; it should be inherent in the product itself, judged by users. A decentralized approach—emphasizing continuous feedback and shared responsibility—builds more resilience than a top-down, centralized approach.

Quality is difficult to define, but it can be summarized as how well a product meets or exceeds user expectations. This definition emphasizes the subjective nature of quality, which varies with consumers and evolves over time.

The pressure on software developers to maintain quality increases as technology advances rapidly. Historically, companies like Ford learned the hard way that leadership-driven quality initiatives can fail without sustained commitment. Ford's “Quality is Job 1” campaign in the 1980s aimed to regain market share lost to foreign competitors by prioritizing quality. Initially successful, Ford later relaxed its focus on quality, contributing to its decline.

The article discusses the new feature in C++26 called std::optional<T&>, which allows developers to represent optional references in a safer way. Here are the key points:

1. Background: std::optional was introduced in C++17 to represent an optional value. However, it couldn't hold references. C++26 addresses this by introducing std::optional<T&>.

2. What is std::optional<T&>?:

   • It does not own the object; it merely refers to an existing one.
   • It combines reference and value-like semantics.
   • It behaves like a pointer that can be null.

3. Benefits: This feature reduces the need for raw pointers, making code more expressive and less error-prone.

4. Key Design Choices:

   • Assignments to std::optional<T&> rebind the reference instead of copying, preventing unintended behaviors.
   • make_optional() creates an owning std::optional<T> instead of std::optional<T&>, avoiding potential dangling references.

5. Constness: The design uses shallow constness, meaning dereferencing a const optional<T&> still gives a non-const reference.

6. Value Retrieval: The method value_or returns a value instead of a reference to maintain safety and avoid surprises.

In conclusion, std::optional<T&> enhances C++ by providing a safer alternative for managing optional references, improving code clarity and reducing reliance on raw pointers.

Summary: Comprehension Debt in LLM-Generated Code

Developers are increasingly facing challenges when modifying or fixing code generated by Large Language Models (LLMs). This is similar to dealing with old legacy systems, where understanding the code is essential before making changes. However, LLMs generate vast amounts of code quickly, creating a new problem known as "comprehension debt."

Some teams take the time to review and understand LLM-generated code, which slows down their workflow, negating any time saved from using LLMs. Others hastily add unreviewed code to their projects, risking future complications.

While LLMs can assist in code editing, they often fall short, leading to frustrating cycles where the tool cannot adequately resolve issues. This means developers will frequently need to manually edit the code, increasing the time needed to comprehend it.

Overall, the reliance on LLMs is creating a growing backlog of "comprehension debt" that developers must address.

The article discusses a method for organizing Slack channels based on urgency rather than topic. The author, Mark, found that rearranging his channels by "how often" he needs to read them made him more responsive and less stressed. He categorized channels into four groups: "Read Now," "Read Hourly," "Read Daily," and "Read Whenever." This approach helps him focus on urgent messages first, reducing burnout from noisy channels and ensuring he doesn't miss important information.

Mark suggests using a flexible framework to prioritize channels based on their importance and his level of involvement. He emphasizes that organizing channels by "what" they are (like team or project) is less effective because it doesn’t reflect urgency. The goal is to quickly identify which channels require immediate attention, making it easier to maintain productivity and achieve Inbox Zero on Slack. He encourages others to try this method for better management of their Slack communications.

Summary of DEML (DAG Elevation Markup Language)

DEML is a new language designed for representing Directed Acyclic Graphs (DAGs) more intuitively than existing graph languages like Graphviz and Mermaid. It uses an elevation-based system where nodes are organized by their relationships, similar to how rivers flow downhill.

The text is asking someone about their current projects and if they have any new ideas they are considering.

This website focuses on the Sun Microsystems Network File System (NFS), which started in 1983 and is still important for modern computer systems. The project celebrated its 40th anniversary in September 2025 during the MSST Conference in Santa Clara, CA.

The site contains various materials, including design documents, engineering specifications, research papers, and marketing content. It is organized into four sections:

1. Source and specifications
2. Documents about NFS
3. Documents on related work
4. Photos

Most materials can be downloaded freely. There is also a list of related Internet RFCs available. Additionally, there is a reference to another site (nfsv4bat.org) that has more NFS materials post-1995, but it may be slow and insecure.

The website was created with contributions from several individuals, and comments or suggestions can be sent to the creator, Geoff Arnold. The site was last updated on September 24, 2025.

The Wikimedia Foundation has released a Human Rights Impact Assessment (HRIA) on how artificial intelligence (AI) and machine learning (ML) interact with Wikimedia projects. The Foundation believes that access to knowledge is a human right and aims to ensure that everyone can freely access and share reliable information.

The assessment was conducted to understand the potential impacts, both positive and negative, of AI and ML on human rights within the Wikimedia ecosystem. It highlights that while AI tools can assist volunteers in managing content, there are risks, such as biases in knowledge representation and the potential for harmful content generation. The report emphasizes the need for careful management of these technologies to protect the rights of Wikimedia volunteers and users.

Key findings include:

• AI tools developed by the Foundation can promote human rights but also pose risks if not properly managed.
• Generative AI may lead to increased disinformation and harmful content.
• Content from Wikimedia projects used to train AI models could result in biases and cultural insensitivity.

The Foundation encourages discussions with volunteer communities to address these findings and implement necessary recommendations. They invite feedback on how to responsibly utilize AI and ML to enhance Wikimedia projects while safeguarding human rights.

In Japan and the EU, Open Source licenses are viewed as contract agreements. However, in the United States, Open Source licenses are seen as "unilateral permission" rather than contracts. This difference in perspective is significant because the U.S. is the primary origin of Open Source practices.

Summary: Selling Lemons: The Hidden Costs of the Meta Game

The concept of "a market for lemons," introduced by economist George Akerlof, describes how information gaps between buyers and sellers can lead to market failures. When buyers can't tell the difference between good and bad products, the average price drops, causing quality goods to leave the market. This results in a prevalence of lower-quality products, or "lemons."

The author argues that the internet has entered a "lemon stage," where online shopping is plagued by low-quality, generic products that overshadow better options. This is driven by sellers using marketing tactics to gain visibility rather than focusing on product quality.

This problem extends beyond e-commerce to areas like online dating and hiring, where participants and companies struggle to distinguish between high-quality and mediocre options due to similar information asymmetries. In hiring, for example, both candidates and employers often misrepresent themselves, leading to inefficiencies and a downward spiral in quality.

The author warns that this focus on optimizing for visibility and algorithms (the "meta") detracts from the actual quality of products and services. The emphasis on outcomes over outputs can lead to poor results, as the actual work gets overlooked in favor of superficial strategies.

Ultimately, the article calls for a return to focusing on product quality and real value creation, rather than getting lost in the complexities of market manipulation.

In 2020, during the pandemic, the author began learning Spanish through Duolingo, hoping to prepare for a potential taco truck venture in Mexico. After five years and an 1800-day streak, they found their Spanish skills lacking, unable to write in the language despite recognizing some words and sentences.

Duolingo's gamification features, like XP points and leagues, did not motivate the author. They struggled to understand how XP correlated with language learning and felt detached from the social aspects, as interactions were superficial and lacked genuine engagement. The forums for discussion, which were previously helpful, were removed, diminishing the sense of community.

While the author found some value in maintaining a learning streak, it did not equate to effective language acquisition, as they could easily repeat old lessons without true understanding. They later compared Duolingo’s methods with those of Language Transfer, realizing that Duolingo's approach of translating sentences without adequate grammar instruction was insufficient.

The author criticized Duolingo's focus on user retention over quality education, noting that the company prioritized expanding its user base and creating content with AI rather than improving the learning experience. After moving to Japan, the author shifted their focus to learning Japanese using other resources, such as group lessons, flashcards, and specialized platforms like Wanikani and Bunpro, which provided more targeted and effective learning opportunities.

Larry Sanger presents nine theses aimed at reforming Wikipedia, motivated by a desire for truth and justice. Here are the key points summarized:

1. End Consensus Decision-Making: The current practice of making decisions through consensus is flawed and stifles dissent. Sanger argues it should be replaced, as it has become a tool for those in power to marginalize others.

2. Allow Competing Articles: To achieve true neutrality, Wikipedia should allow multiple articles on the same topic, each representing different perspectives. This would help mitigate the existing bias towards a narrow viewpoint.

3. Abolish Source Blacklists: Wikipedia currently maintains a list of disallowed sources that unfairly excludes certain media outlets. Sanger advocates for a more open approach to referencing sources.

4. Revive True Neutrality: The neutrality policy needs to be strengthened to ensure all viewpoints, especially marginalized ones, are represented fairly.

5. Repeal “Ignore All Rules”: This rule, intended to encourage newcomers, has become a shield for insiders. It should be removed to promote accountability.

6. Identify Wikipedia Leaders: Transparency is essential. Those in leadership positions should reveal their identities to ensure accountability.

7. Public Article Ratings: Sanger calls for a public feedback system for articles to improve quality and respect user opinions.

8. End Indefinite Blocking: The practice of permanently banning users is unjust and should be reformed to allow for more leniency and oversight.

9. Establish a Legislative Process: Wikipedia's policy-making process is weak. A more democratic approach, such as an elected editorial assembly, is necessary for effective governance.

Sanger also mentions additional proposals, including supporting a decentralized encyclopedia network and implementing performance reviews for administrators. Overall, he urges the Wikipedia community to embrace these reforms to enhance the platform's credibility and inclusivity.
