The text explains the concept of tangent space, which is essential for normal mapping in 3D graphics. Here are the key points simplified:

1. What is Tangent Space?

   • Tangent space is a local coordinate system at each point on a 3D surface. It helps connect 2D texture coordinates (UVs) to the 3D surface geometry.

2. Why is it Important?

   • It allows for accurate lighting and shading on surfaces by defining how texture movements relate to real-world movements on the surface.

3. How is Tangent Space Defined?

   • Tangent space consists of a tangent plane at each surface point, defined by:
     • A normal vector (perpendicular to the surface)
     • Two tangent vectors (defining directions on the surface)

4. Role of UV Coordinates:

   • UV mappings provide 2D coordinates for each point on the surface and help determine the orientation of the tangent frame.

5. Constructing Tangent Space:

   • Tangent vectors are derived from how texture coordinates correspond to the surface geometry. They need to be orthogonal (perpendicular) for accurate lighting.

6. Using Tangent Space in Normal Mapping:

   • Normal maps store surface orientations as colors, which when sampled, need to be transformed into the tangent space to interact correctly with lighting.

7. Implementation:

   • In graphics programming, the tangent space is typically built during mesh processing and utilized in shaders to enhance the visual detail of low-resolution models.

8. Conclusion:

   • Tangent space is not just a trick for rendering; it is fundamentally tied to how surfaces are defined and how textures interact with them, making it crucial for realistic appearance in 3D graphics.

Transmeta was the last major IPO of the dotcom era, launching on November 7, 2000, and raising $273 million. While some consider it the last successful tech IPO until Google in 2004, it didn't fully fit the dotcom mold as a hardware company. After its IPO, the market for technology and Internet IPOs declined significantly, particularly after the 9/11 attacks.

Transmeta produced CPUs and was notable for having Linus Torvalds, the creator of Linux, as an employee. The company aimed to create an efficient x86-compatible CPU using a software translation layer, but it struggled to compete with Intel and AMD in performance. Their products, the Crusoe and Efficieon CPUs, found limited success, mainly in low-power applications.

Ultimately, Transmeta shifted from selling CPUs to licensing its technology in 2005 and was sold to Novafora in 2009, which later ceased operations. Today, Transmeta products are rare collectibles but lack a strong nostalgic following.

After getting a flu vaccine, the author was offered a blood pressure test that showed concerning results. A pharmacist suggested a 24-hour monitoring study, attaching a device to the author's arm to record measurements periodically. The author was curious about the data but was told not to look at it to avoid stress.

Upon returning to the office, the author researched the device, a Microlife WatchBP O3, and attempted to access its data using available software. After some difficulty, they set up a Windows virtual machine to use the software, but found it inconvenient.

Determined to analyze the data, the author used Wireshark to capture the communication between the device and the virtual machine. They identified patterns in the data packets that included their blood pressure readings and heart rate. Despite some confusion with the data structure and timestamps, the author made progress in understanding how the device encoded information.

The author tried to write code to better extract data but faced challenges and deadlines. Ultimately, they had to return the device, gaining experience in reverse engineering and learning new medical terms like "normotension" (normal blood pressure) and "white coat hypertension" (higher readings in clinical settings). The author humorously concluded that getting blood pressure checked right after a flu shot might not be the best idea.

The blog post discusses how Friedrich Nietzsche's philosophy can help us understand the challenges posed by artificial intelligence (AI) in today's society. As AI transforms work, relationships, and ethics, people face an existential crisis similar to the one Nietzsche addressed during the industrial revolution.

Key points include:

1. Human Value Creation: Nietzsche believed that individuals should create their own values and meaning through self-overcoming and personal responsibility. This idea is relevant as AI threatens traditional jobs and social structures, leading to a crisis of meaning for many.

2. Work Displacement: The rise of AI is displacing millions of jobs, especially for low- and mid-skill workers. This loss not only affects livelihoods but also personal identity and societal recognition, leading to increased mental health issues.

3. Erosion of Relationships: AI is changing how people connect, with machines simulating emotional interactions. This can lead to feelings of loneliness and emptiness, as genuine human relationships are replaced by artificial ones.

4. Fragmentation of Moral Frameworks: AI systems often make decisions without transparency, eroding shared ethical norms and leaving individuals without clear guidelines for trust and responsibility.

While Nietzsche’s ideas promote individual strength and authenticity, they don't fully address the systemic issues of today's technology. The author argues for a new philosophy that combines Nietzsche's insights with an understanding of the need for collective responsibility and ethical governance in the age of AI. This approach aims to foster both personal meaning and a shared sense of purpose in an increasingly automated world.

The author created a modification for a Vornado 633DC fan, allowing remote control via WiFi while keeping the changes hidden inside the fan. Key components include a digital potentiometer (digipot) to control the fan speed electronically instead of manually. The project began with the desire to control the fan's speed remotely, as using a smart plug only allowed for basic on/off control.

The author researched the fan's internal components, discovering how the speed control worked and concluded that a digital solution could replace the traditional potentiometer. After testing the concept with a breadboard, the author designed a custom PCB that would fit inside the fan’s housing without permanently altering it.

The design process involved careful selection of components, including using an ESP32 chip for connectivity and a rotary encoder for physical speed control. The PCB was assembled with most components pre-soldered to simplify the process.

The final modification allows for remote control of the fan's speed and status feedback through an RGB LED, all while maintaining the original manual controls. The project is fully reversible, preserving the fan's original state. Links to the schematic, PCB design, and configuration details are provided for those interested in replicating the project.

Summary of "Agentic Pelican on a Bicycle"

Simon Willison has created an informal benchmark by prompting AI models to generate an SVG image of a pelican riding a bicycle. This task, while absurd, highlights how AI models can improve their outputs through an iterative process known as the agentic loop—generate, assess, and improve.

In an experiment, models were allowed to see their output and make self-corrections. They generated an SVG, converted it to JPG, then improved the SVG based on what they observed in the JPG. The experiment used six multimodal AI models, including different versions of Claude and GPT.

The results varied:

• Claude Opus 4.1 made significant improvements in realism and mechanical coherence.
• Claude Sonnet 4.5 focused on subtle refinements in shape and detail.
• Claude Haiku 4.5 made extensive adjustments over six iterations, but results were not dramatically better.
• GPT-5 Medium and GPT-5-Codex Medium refined their images but had different approaches, with Codex complicating its output unnecessarily.
• Gemini 2.5 Pro fundamentally changed the arrangement of elements in its image.

Key takeaways include:

• Some models made thoughtful improvements, while others were more about minor tweaks.
• The ability to self-critique and know when to stop is crucial for effective output improvement.
• The agentic approach differs from zero-shot generation, revealing the models' capacities for evaluation and self-improvement.

Overall, the experiment shows that while models can refine their work, their ability to do so effectively depends on their design and judgment skills.

The article discusses how the effort involved in creating high-quality work increases significantly as the perceived quality rises. The author argues that creating art is a complex process that involves both exploration (generating ideas) and exploitation (refining those ideas), which happen simultaneously rather than in separate phases.

As the resolution of a project increases, the range of acceptable changes becomes narrower, making it harder to improve without risking quality. This leads to a lot of fine-tuning and edits that feel like they require more effort than expected. For example, in music, even tiny timing changes can greatly affect the groove, while in prose, there are more options that work well together.

The article also contrasts different creative fields, noting that some, like jazz or drawing, allow for more real-time exploration and mistakes, while others require more precision and practice. Ultimately, the author concludes that the process of refining creative work is challenging and requires significant effort as one strives for higher quality.

Earlier this year, I attended the dConstruct web conference in Brighton, UK, where I caught up with friends. After the conference, we relaxed in a park and discussed an Egyptian exhibit at a nearby museum. One of my friends, Mike, made a clever remark about the exhibit's title, which led us to appreciate that someone could read 5,000-year-old hieroglyphs.

Inspired by this, I jokingly suggested creating a t-shirt that said "Hello World" in hieroglyphics. However, I learned that ancient Egyptian didn't have a glyph for the letter 'L'. Despite this, we reached out to Egyptology experts for help with the translation. In the end, we settled on the phrase "Welcome, the entire land," which is a unique greeting from a long-lost culture.

The hieroglyphs were artistically designed, and I printed them on a t-shirt. I love that only a small number of people can understand it, and I encourage others to use the design for their own items. Special thanks to Mike and the Egypt Exploration Society for their help with this fun project.

The text discusses the challenges of programming with multiple CPU cores, particularly focusing on the issues that arise from managing shared mutable state in concurrent systems. Here are the key points simplified:

1. Parallel Computing: Modern computers have multiple CPU cores, making it crucial to use parallel computing effectively. However, managing shared data between threads is complex.

2. Data Races: A data race occurs when multiple threads access the same memory location simultaneously, leading to unpredictable results. For example, two threads trying to withdraw from the same bank account can cause incorrect balances.

3. Mutexes: Mutexes are a common solution to prevent data races by ensuring that only one thread can access a resource at a time. However, they have limitations:

   • They can lead to deadlocks, where two threads are stuck waiting on each other.
   • They require careful management and can complicate code, making it harder to maintain.

4. Composition Issues: Using mutexes often requires breaking encapsulation and duplicating code for synchronized and unsynchronized operations, which complicates the design.

5. Software Transactional Memory (STM): STM is presented as a superior alternative to mutexes. It allows multiple operations to be treated as a single atomic transaction, preventing data races and deadlocks. If a conflict occurs during a transaction, it can be rolled back and retried, simplifying code and improving safety.

6. Concurrency Patterns: Actor systems and Communicating Sequential Processes (CSP) are alternative approaches that can help manage concurrency without the pitfalls of shared mutable state.

7. Recommendations: The author suggests considering languages that support STM or adopting immutable data structures to avoid many concurrency issues.

In summary, while mutexes are commonly used, they introduce significant challenges in concurrent programming. Alternatives like STM provide more reliable and manageable solutions, making them preferable in many scenarios involving parallelism.

Researchers are constantly looking for ways to improve optimization, with Adam being the most popular optimizer. New methods, called spectral-whitening optimizers, claim to outperform Adam.

2. Gradient Calculation: The gradient helps determine how to adjust model parameters to reduce loss. However, the traditional method assumes a simple Euclidean distance, which may not be optimal for all parameters. Using a more complex metric can improve performance.

3. Whitening Metric: Modern optimizers often use a "whitening" metric, which helps ensure that all parameters update at their optimal rates. This metric is derived from the Gauss-Newton matrix, which approximates the curvature of the loss function.

4. Comparison with Other Methods: The whitening metric relates to several optimization techniques, including:

   • Newton's Method: Uses the Hessian matrix but is computationally expensive.
   • Natural Gradient Descent: Uses the Fisher information matrix, focusing on the shape of the probability distribution rather than the loss function.
   • Spectral Norm Descent: Measures distance based on the maximum singular value of the matrix.

5. Popular Optimizers:

   • Adam/RMSProp: Uses an element-wise approximation of the whitening metric.
   • Shampoo and SOAP: Track gradient covariances using Kronecker factors for better performance.
   • PSGD: An iterative approach that updates a preconditioner matrix.
   • Muon: Approximates the SVD efficiently to improve optimization.

6. Benchmarking: Experiments show that spectral-whitening optimizers like SOAP outperform Adam in terms of performance per gradient step, especially when hyperparameters are well-tuned.

7. Conclusions: Spectral-whitening methods generally improve over Adam. SOAP is noted for its effectiveness, while Muon is recognized for its computational efficiency. Further exploration is encouraged to develop even more effective optimization methods.

This summary captures the main ideas about modern optimizers and their evolution, focusing on improving training efficiency in machine learning models.

Bank of America recently reported a significant increase in borrowing among major tech companies to fund their artificial intelligence (AI) projects. In September and October, companies like Meta, Oracle, and others issued $75 billion in bonds and loans, more than double the average annual borrowing over the past decade.

As companies invest heavily in AI, their capital expenditures are expected to reach 94% of their operating cash flow by 2025 and 2026, up from 76% in 2024. This shift raises concerns about sustainable growth since companies may increasingly rely on debt to finance the necessary infrastructure for AI.

Tech companies have traditionally funded their AI expansions with strong cash flows from core businesses. However, the current scale of data center investments is pushing them to seek external financing. Although cash flows remain healthy overall, the rapid pace of investment exceeds what internal funds can support.

Many tech firms already have considerable debt, and while some, like Meta, have large cash reserves, others, like Oracle, may face challenges if interest rates rise. Smaller companies may struggle even more with higher borrowing costs due to lower credit ratings.

Investing in AI carries risks, as reliance on debt might accelerate growth but also increase vulnerability to market fluctuations. Companies with diverse revenue streams, like Microsoft and Amazon, are better positioned to manage these risks. However, there are concerns about a potential debt bubble and the sustainability of current high valuations.

In summary, investors should be cautious about investing in AI-driven companies, monitoring their debt levels and the return on their capital expenditures, as the landscape of AI funding evolves.

True spatial intelligence in AI could revolutionize areas like storytelling, robotics, and scientific research, making machines more intuitive and effective collaborators.

To achieve this, Li's team at World Labs is working on "world models," which would enable AI to understand and generate complex environments. These models need to be generative, multimodal, and interactive, allowing AI to create worlds that are physically and geometrically consistent while understanding inputs from various sources.

Li emphasizes the importance of developing AI that enhances human capabilities rather than replacing them, highlighting the potential for spatial intelligence to improve creativity, robotics, healthcare, and education. Overall, the aim is to create AI that becomes a true partner in addressing complex challenges and enhancing human life.

Summary of "The Write Last, Read First Rule"

TigerBeetle is a financial transactions database focused on correctness. However, creating a reliable system from individual correct parts can be challenging. This article discusses how to maintain consistency without transactions, manage external states, and recover from failures.

Key Points:

1. System Structure: TigerBeetle specializes in handling financial transactions (like moving money), while Postgres manages master data (like account holder information). This separation allows scalability and security.

2. Transactions: A transaction is a complete set of operations that either commits (succeeds) or aborts (fails). However, combining operations from both TigerBeetle and Postgres does not guarantee a complete transaction.

3. Safety Properties:

   • Consistency: Every account in Postgres should have a corresponding account in TigerBeetle, and vice versa.
   • Traceability: Accounts with a positive balance in TigerBeetle must exist in Postgres to avoid losing money.

4. System of Record vs. System of Reference:

   • The System of Record is the primary source of truth (TigerBeetle).
   • The System of Reference supports the record (Postgres).
   • Order of operations is crucial; write to the reference first and then to the record.

5. Correctness in Operations: The principle "Write Last, Read First" ensures that the application remains consistent. Correct ordering of operations is essential to avoid errors.

6. Implementation: Clients interact through an Application Programming Interface (API) that orchestrates operations between the subsystems. The API ensures that operations are idempotent, meaning repeating an operation won't change the outcome after the first application.

7. Error Handling: The system must detect and manage errors. If operations violate expected order or create conflicts, the system will alert the operator.

8. Conclusion: Without transactions, careful coordination is key for maintaining correctness. By defining clear roles for systems and orderly operations, one can build reliable applications from reliable components.

The article discusses the history of Soviet-made cars in Singapore from the late 1970s to the 1990s. During this period, Singapore mainly imported cars from various countries, with Japanese brands like Toyota and Honda being the most popular. However, trade with the Soviet Union increased significantly in the late 1970s, leading to the introduction of Soviet cars like Lada and Volga in Singapore.

In 1977, Volga taxis were introduced as affordable, comfortable vehicles, while the Lada 1200, a model similar to the Fiat 124, also made its debut. Despite being less expensive than competitors, Lada struggled with sales and quality issues, leading to the end of its distribution rights by 1981. A brief revival in the late 1980s brought models like the Lada Samara, but they faced ongoing design and reliability challenges.

The article also notes that, following the Soviet Union's collapse in 1991, the reputation of Lada cars declined, and they eventually disappeared from Singapore's roads. Today, the rarest car brands in Singapore include various vintage and luxury models, with only a handful of each brand registered.

Physicists have recently reformulated quantum mechanics using only real numbers, eliminating the imaginary number (i) (the square root of -1) that has long been a source of confusion in the field. For over a century, the equations of quantum physics relied on complex numbers, which include both real and imaginary components, to describe behaviors of particles and atoms.

The initial use of (i) was met with skepticism, and physicist Erwin Schrödinger hoped to find a purely real version of his equation. However, (i) remained in use, as it provided practical benefits for calculations. Recent studies initially supported the idea that complex numbers were essential for quantum mechanics. Yet, new research from teams in Germany and France has demonstrated that it is possible to formulate an equivalent theory using only real numbers.

While this new approach avoids (i), it still reflects some of the unique properties of complex numbers, suggesting that the mathematical structure of quantum mechanics may still have connections to complex arithmetic. The debate continues about whether complex numbers are needed, as some researchers argue they fit naturally into the theory, making it simpler and more elegant.

Overall, while physicists can describe quantum phenomena without using imaginary numbers, the simplicity and effectiveness of complex numbers in quantum mechanics may still hold significant relevance in understanding the nature of reality.

Summary of Secure Coding in JavaScript

JavaScript is widely used on the internet, making it a common target for attackers. Here are ten key tips for writing more secure JavaScript to protect your applications:

1. Cross-Site Scripting (XSS): This is a major security risk where attackers can inject malicious code into your application. Always validate user input and use output encoding to prevent XSS.

2. Use Secure Frameworks: Frameworks like React, Angular, and Vue.js help automatically encode output, reducing the risk of XSS.

3. Avoid Inline Scripting: Keep JavaScript in separate files to enhance security and organization, preventing inline vulnerabilities.

4. Use Strict Mode: Enabling strict mode in JavaScript helps write cleaner and safer code by enforcing stricter syntax rules.

5. Utilize Open Source Tools: Leverage free tools like DomPurify, Retire.js, and others to help identify and mitigate security risks.

6. Clarify Text in Code: Ensure that user-provided text is treated as data and not executable code by using methods like innerText instead of innerHTML.

7. Limit Dynamic Attributes: Only use safe, static attributes when setting values from user input to avoid potential risks.

8. Backend Validation: Always validate input on the server side to ensure security, as front-end validation can be bypassed.

9. Avoid Dangerous Functions: Steer clear of functions like eval() and innerHTML when working with user data, as they can introduce vulnerabilities.

10. Implement General Security Practices: Follow standard secure coding practices like input validation, encryption, and using a secure development lifecycle (SDLC) to enhance overall security.

By starting with a few of these best practices and sharing knowledge with others, developers can significantly improve the security of their JavaScript applications.

The article discusses the need for UK users to transition away from Apple services due to the withdrawal of Apple's Advanced Data Protection (ADP) feature, which is being removed in compliance with the UK government's Investigatory Powers Act. Users who had ADP enabled will have to turn it off manually to retain their iCloud accounts.

Key points include:

1. ADP Removal: Apple is discontinuing ADP in the UK, meaning new users will not have access to it, and existing users must disable it themselves.

2. Data Protection: While certain iCloud data categories will still be protected by standard encryption, users who rely on end-to-end encryption (E2EE) for security should move their sensitive data off iCloud.

3. Data Management: Users are advised to purge their iCloud accounts and consider alternative services that offer E2EE, such as Proton, Standard Notes, Obsidian, or Joplin.

4. Global Impact: The changes currently affect only UK users, while other regions retain ADP. However, UK users' data security is at risk due to the government's demands for access to iCloud data.

5. Ongoing Developments: The article mentions a second request from the UK government, which raises concerns about data security based on users' nationality.

The author emphasizes the importance of managing personal data security and encourages readers to take action to protect their information.

The text emphasizes that vertical integration is crucial for improving developer productivity and tool effectiveness. Vertical integration means having different tools in a workflow tightly connected, allowing for seamless interactions and efficiencies.

Key points include:

1. Definition of Vertical Integration: It involves tight integration of various tools in the development process, enabling workflows that save time and reduce friction.

2. Examples of Benefits:

   • Quick builds due to shared artifacts.
   • Easy navigation between failing tests and code editors.
   • Automatic handling of deployment failures.
   • Immediate access to relevant code across projects and languages.

3. Current Challenges:

   • Existing tools often lack the cooperation needed for effective integration, leading to inefficient workflows.
   • Open source projects tend to be smaller and less motivated to adopt complex integrations.
   • Industry users face challenges in switching to integrated systems due to high migration costs and existing complexities in their workflows.

4. Market Viability:

   • Building a commercially viable vertically-integrated stack is difficult due to the need for extensive integrations and the reluctance of large organizations to adopt new tools.
   • Smaller companies may hesitate to adopt integrated solutions due to fears of vendor instability and high migration costs.

5. Conclusion: Vertical integration is essential for maximizing the value of developer tools, but creating and selling such integrated systems is complex and fraught with challenges. Hence, achieving effective vertical integration remains a significant hurdle in the industry.

Sai and Aayush are developing Hypercubic, an AI platform designed to help large companies manage and update their mainframe systems, which are still crucial for industries like banking and insurance. Many of these systems use COBOL, a programming language from the 1960s, and 70% of Fortune 500 companies still rely on them. However, the engineers familiar with these systems are retiring, leaving a gap in knowledge about how they function.

Hypercubic aims to address this challenge by capturing the essential human insights and reasoning behind these systems. It has two main tools:

1. HyperDocs: This tool analyzes COBOL and other related code to create clear documentation, architecture diagrams, and dependency graphs. It saves time compared to traditional methods of reverse-engineering these systems.

2. HyperTwin: This tool gathers knowledge from current experts by observing their work and conducting AI-driven interviews. It builds a digital representation of how these experts troubleshoot and maintain the systems.

Together, these tools create a comprehensive knowledge graph that connects the code, systems, and the human reasoning behind them. Hypercubic aims to make legacy system modernization easier and more effective by preserving crucial knowledge that is often lost.

They welcome feedback, especially from those with experience in mainframes or legacy system modernization.

Text rendering is a challenging task for developers, involving complex issues like layout, Unicode, and rendering speeds. The author has focused on creating text effects quickly using GPU technology, emphasizing the use of signed distance fields (SDF) for anti-aliasing and other effects.

The article explains how to compute SDF on the GPU, which is faster than CPU calculations, especially for mobile devices. Key processes include:

1. Extracting Glyphs: Glyphs are defined by outlines made of Bézier curves. The author shows how to hard-code these outlines and provides a method for managing them efficiently in shaders.

2. Distance Calculation: The distance from a point to the shape is determined by checking all Bézier curves that make up the glyph and selecting the shortest distance.

3. Optimizations: The author discusses optimizations such as using bounding boxes to reduce computations and finding an initial best guess for distances to improve performance.

4. Winding Number for Shape: To determine if a point is inside or outside a shape, a winding number algorithm is implemented, which counts crossings of a ray through the shape.

5. Limitations: The article notes challenges like overlapping shapes and the complexity of rendering certain glyphs, which can lead to visual glitches.

6. Effects: Despite the limitations, having a distance field allows for various visual effects, such as anti-aliasing, outlines, and glow effects, enhancing text visibility and aesthetics.

The author concludes by expressing hope that their experience will help others interested in text rendering, despite the challenges faced.
