On December 5, 2025, Cloudflare experienced a network outage starting at 08:47 UTC, lasting about 25 minutes and affecting roughly 28% of its HTTP traffic. The issue was not due to a cyber attack but resulted from changes made to their body parsing logic while addressing a security vulnerability in React Server Components.

During the incident, customers whose websites were served by an older version of Cloudflare's proxy and who had a specific ruleset applied encountered HTTP 500 errors. The problem arose from an internal tool that was disabled as a precaution, which inadvertently triggered a coding error in the system.

Cloudflare acknowledged this incident followed another outage on November 18, 2025, and expressed their commitment to preventing future occurrences. They are working on improvements, including enhanced rollout processes, better error handling, and streamlined operations to minimize the impact of any changes made to the network.

A detailed report on their resilience projects will be published soon, and they have temporarily halted changes to ensure better rollback and mitigation systems. Cloudflare apologized for the disruption caused to their customers and the internet community.

NASA's asteroid Bennu has revealed important findings about the early solar system and the origins of life through samples collected by the OSIRIS-REx mission. Recent studies published in scientific journals highlight three major discoveries:

1. Essential Sugars: Researchers found two types of sugars, ribose and glucose, in the Bennu samples. Ribose is crucial for RNA, while glucose is a key energy source for life. This suggests that the building blocks of life were widespread in the solar system, supporting the idea that life on Earth may have originated from extraterrestrial materials.

2. Ancient ‘Gum’: A mysterious gum-like substance was discovered in the samples, which has never been seen before in space materials. This ancient material, rich in nitrogen and oxygen, likely formed during the early solar system and could have provided essential chemical precursors for the emergence of life on Earth.

3. Supernova Dust: The analysis of dust from stars that existed before our solar system showed that Bennu's parent body contained a high amount of supernova dust. This indicates that it formed in a region rich in materials from dying stars, which may provide insights into the conditions of the early solar system.

Overall, these findings enhance our understanding of the ingredients necessary for life and the processes that occurred in the early solar system.

In democracies, major decisions usually need majority support, so leaders (elites) must gain public backing. Traditionally, they relied on education and media to influence opinions. However, advancements in AI have made it cheaper and easier to shape public opinion. This creates a situation where elites can intentionally design public preferences.

A model suggests that when one elite tries to influence opinions, it often leads to greater polarization, meaning people have more extreme, divided views. Advances in persuasion technology make this polarization happen faster. When two opposing elites take turns in power, the same technology can lead to more cohesive opinions or "semi-lock" regions, making it difficult for rivals to change public views.

Overall, the ability to persuade easily changes how elites use polarization as a strategic tool for governance, which could impact the stability of democracy as AI continues to develop.

The article argues that transparent leadership is more effective than servant leadership. The author, who has experience in management, feels that servant leadership, which involves anticipating problems and clearing obstacles for team members, can lead to dependency and isolation when the leader is no longer present.

Transparent leadership, as proposed by the author, focuses on coaching, connecting, and teaching team members to solve problems independently. It emphasizes clear communication of values and principles, allowing direct reports to grow in their roles by gradually taking on leadership responsibilities, and continuously preparing a successor.

Instead of becoming a bureaucratic middle manager, the author suggests that leaders should stay engaged in technical work to maintain their skills and earn respect from their teams, ultimately aiming to make themselves redundant in a constructive way.

The author reflects on their experience re-engaging with technology, specifically using a Raspberry Pi to create a remote-controlled car for home monitoring. After a busy work period focused on AI projects, they wanted to explore physical AI, particularly to alleviate their worries about home safety.

They purchased a Raspberry Pi Zero 2 W on sale and found it more enjoyable to use than previous microcontrollers. To build the RC car, they used a simple 2WD kit and added components like a motor driver and a USB camera for video streaming.

To set up the Raspberry Pi, they installed an operating system, configured it for remote access via SSH, and created a web interface to control the car and view live video. They used Nginx to streamline access to different components through a single URL.

To ensure the system runs automatically after a reboot, they utilized systemd to manage services. Finally, they set up a Cloudflare Tunnel to access the car remotely without compromising their home network security. The project allowed them to monitor their home while away, although they humorously acknowledged a new worry about battery safety. The author expresses excitement about discovering the capabilities of Raspberry Pi and hopes to inspire others to explore similar projects.

Summary: Stacked Diffs with git rebase --onto

Using git rebase --onto helps manage multiple dependent branches (stacked diffs) efficiently without including irrelevant commits. This technique is beneficial for larger features split into smaller, review-friendly pull requests (PRs).

Key Points:

1. Why Use Stacked Diffs?

   • They allow you to break down large features into smaller PRs, making them easier to review and approve.

2. Regular Rebase vs. Rebase --onto:

   • A regular rebase replays commits on the target branch, but it can lead to issues with stacked branches, causing duplicates or conflicts when the base branch updates.
   • git rebase --onto allows you to specify which commits to move and where, preventing these issues.

3. How to Use git rebase --onto:

   • Create a marker branch to track the base state of your feature branch.
   • When the main branch updates, rebase the dependent branches using the --onto command to keep them in sync.

4. Post-Merge Cleanup:

   • After merging the base branch into your feature, you can clean up your commit history by removing the old commits from the rebase.

5. Tips:

   • Always update your marker branch after rebasing.
   • Be prepared to force push after rebases, as commit hashes change.
   • Limit the depth of your stacked diffs to avoid complexity.

In summary, while this workflow may seem complex, it leads to better-organized PRs and streamlined reviews. Just remember to keep your marker branches updated!

A significant percentage of students at elite universities, such as Stanford (38%), Brown (20%), and Harvard (20%), are claiming academic accommodations typically meant for those with learning disabilities. Many of these students report mental health issues like anxiety and ADHD. Critics suggest that the high acceptance standards of these institutions make it unlikely that so many genuinely disabled students are enrolled.

Some professors argue that many students are using these accommodations to cope with academic pressure rather than having real learning disabilities. While some students truly need help, the current guidelines make it easy to obtain accommodations with just a doctor's note.

The trend may be influenced by how conditions like ADHD and anxiety are discussed online, leading young people to see themselves as part of a broader identity associated with these conditions. Additionally, the current cultural climate encourages students to interpret their struggles as signs of a disability, rather than normal challenges in college.

This rise in accommodations is viewed as a way for students to cope with the fear of failure. While they may achieve better grades through these aids, critics argue that this approach ultimately hinders their personal and intellectual growth, making them less prepared for life's challenges.

The blog post discusses the author's reflections on blogging in 2025, highlighting how the internet has changed drastically since the early days of personal blogging. In the past, many people had their own blogs on platforms like WordPress or Blogger, creating a decentralized web. Today, most content is consumed on major social media platforms, making the web feel smaller.

The rise of AI has also transformed how people find information. Instead of searching through websites, AI provides answers directly, which can limit the visibility of traditional blogs. Additionally, high-quality content is increasingly found behind paywalls or in paid newsletters, making it harder for open web content to compete.

Despite these challenges, the author feels nostalgic and wants to return to blogging. They have updated their blog software to be simpler and more aligned with open web principles by removing unnecessary scripts and dependencies. They also plan to share the code for their blogs on GitHub. Ultimately, the author wonders if anyone will read their posts, as they’ve removed tracking features, leaving them feeling like they are "screaming into the void."

The author reflects on their experiences with three programming languages: Go, Rust, and Zig, after realizing they often use familiar languages for work rather than exploring others. They aim to understand what each language values and how it aligns with their own preferences.

Go is known for its simplicity and minimalism. It's designed to be easy to learn and read, with a focus on stability and efficiency in corporate environments. Although it has fewer features compared to other languages, it allows for clear code with less complexity, making it suitable for many common programming tasks.

Rust, on the other hand, is more complex and feature-rich. It prioritizes safety and performance, which can make it challenging to learn. Rust prevents memory-related errors by using a sophisticated type system and compile-time checks to ensure safe code execution. This complexity helps developers avoid undefined behavior, making it a powerful tool for serious applications.

Zig is the newest of the three and offers a different approach. It emphasizes manual memory management and gives developers complete control. While it lacks certain object-oriented features found in Go and Rust, it encourages a more data-oriented design. Zig aims to simplify programming by removing unnecessary abstractions and is seen as a reaction against the complexities of Go and Rust.

In summary, Go is minimalist and corporate-friendly, Rust is maximalist and focuses on safety, and Zig offers control and simplicity with manual memory management. Each language reflects different values, catering to various programming needs and philosophies.

Colin 't Hart explains that while you can't directly remove values from an enum type in PostgreSQL, you can achieve the same outcome by creating a new enum type without those values. To do this, you should:

1. Ensure the table no longer uses the old values.
2. Create a new enum type without those values.
3. Change the columns to use the new enum type, converting the old values to text in the process.
4. Drop the old enum type.
5. Rename the new type to match the old one.

He suggests that automating this process in PostgreSQL could be beneficial, though it is not urgent.

The latest update in "The Ofcom Files" reveals ongoing tensions between the UK's censorship agency, Ofcom, and the American website 4chan. Ofcom has sent a threatening letter to 4chan after the site refused to pay fines imposed by the UK, claiming authority to enforce its censorship laws on Americans.

In response, Preston Byrne, representing 4chan, emphasized that the site will not comply with Ofcom's age assurance rules, which he argues would compromise user anonymity protected by the First Amendment. He also mentioned a proposed federal law in the U.S. called the GRANITE Act, aimed at shielding American companies from foreign censorship.

Byrne criticized Ofcom for trying to impose its rules on U.S. citizens and expressed hope that the U.S. Congress will protect American internet users from foreign overreach. He remains optimistic about achieving this legal protection soon.

In the past year, large language models (LLMs) have significantly evolved and been more widely used, particularly after the release of a new reasoning model called o1 on December 5, 2024. This model introduced a shift from simple responses to more complex, multi-step reasoning, leading to faster deployment and new applications. However, our understanding of how these models are used in real life has not kept pace.

Using the OpenRouter platform, which provides AI inference for various LLMs, researchers analyzed over 100 trillion interactions with these models. They found that open-weight models are increasingly popular, especially for creative tasks and coding help, rather than just productivity. They also noted a trend called the "Glass Slipper" effect, where early users remain engaged with the models much longer than newer users.

These insights highlight the complex ways people use LLMs and suggest that understanding usage patterns can help improve the design and deployment of these systems.

Summary of Lie Groups

Lie groups, named after mathematician Marius Sophus Lie, merge concepts from group theory, geometry, and linear algebra, making them valuable in mathematics and physics. A group is a set of elements with an operation that combines them, like addition or multiplication. Lie groups focus on continuous symmetries, unlike discrete groups that handle distinct transformations.

For example, the rotations of a Frisbee represent a Lie group called SO(2), which can be visualized as a circle. This continuous nature allows for deeper mathematical analysis through something called a manifold. Lie groups also have associated structures called Lie algebras, which simplify calculations by allowing mathematicians to use linear algebra techniques.

These groups are crucial in understanding fundamental physical forces, like gravity and electromagnetism, because they capture symmetries in nature. Notably, mathematician Emmy Noether showed that each symmetry described by a Lie group corresponds to a conservation law in physics. Today, Lie groups continue to be essential tools for both mathematicians and physicists, highlighting the pervasive role of symmetry in the universe.

Summary of Metaphysical Boldness

Digital physics is a field that views the universe as a massive digital computer, drawing on ideas from figures like Konrad Zuse, John Von Neumann, and Stephen Wolfram. This approach suggests that the fundamental structure of reality may be much simpler than we think. For example, a specific model called the lattice gas automaton can simulate complex fluid dynamics using simple rules.

Rather than relying on hidden complex mathematics, digital physics proposes that the universe operates on straightforward rules, with complex phenomena emerging from this simplicity. This perspective is more daring than many scientific models, which often provide useful predictions without revealing deeper truths about reality. In contrast, digital physics boldly claims that the universe is fundamentally a computer, and all its complexities arise from computational processes.

Summary: Help, My Java Object Vanished (and the GC is Not at Fault)

In this article, Paul Hübner, a developer on the HotSpot Java Virtual Machine (JVM) team, shares his experience of debugging a serious issue in the OpenJDK project where Java objects were seemingly disappearing during testing. This exploration led to a deep dive into the workings of Java, particularly related to the implementation of Project Valhalla and the changes introduced by JEP 450, which aimed to create Compact Object Headers for better memory efficiency.

Key Points:

1. Project Valhalla: This project is focused on enhancing Java with features like value objects, which are defined by their fields rather than identity. This allows for optimizations in how memory is managed.

2. Mark Word Changes: The article discusses changes to the mark word (a part of the object header storing metadata) to support the new Compact Object Headers. This change inadvertently caused numerous test failures across various platforms.

3. Debugging Challenges: Hübner faced widespread, intermittent, and non-obvious test failures, making debugging particularly challenging. The failures were not localized to the JVM but affected applications, leading to issues like null pointer exceptions and class not found errors.

4. Investigation Methodology: He employed a systematic approach to debugging, including changing JVM flags to isolate the problem, which revealed that the failures occurred when using the C2 compiler without Compact Object Headers.

5. Identifying the Bug: After extensive testing and analysis, he discovered that an incorrect bitmask was causing the JVM to mishandle object state during synchronization, resulting in the disappearance of object references.

6. Conclusion: Hübner emphasizes the importance of a structured debugging methodology, collaboration, and utilizing tools effectively in tackling complex issues in large codebases like the JVM.

The article serves as both a technical exploration of JVM internals and a narrative of the challenges faced in software development, highlighting valuable lessons learned throughout the debugging process.

The author is working on debugging a simulation of a ship in a system that appears to be generating issues with gliders, particularly during a specific time period (65532M to 86663M). They have identified a problem related to a "cordership" that produces backward gliders, which affects the simulation output. The author has recomputed the "switch far seed" multiple times and plans to refine it to handle these gliders.

To speed up debugging, they mention using a narrow beam and techniques shown to them by another user, which could help them reach a specific starting point in their simulation more quickly. The current debugging process is complex and time-consuming, potentially taking weeks or months in some contexts. However, they believe they can finish the project in about a week, needing only one more day to complete their work.

In summary, the main points are:

1. The simulation has issues with gliders during a specific time frame.
2. The author is refining the "switch far seed" to handle backward gliders.
3. They are utilizing methods to speed up the debugging process.
4. The goal is to finish the project soon, but the complexity of debugging makes it challenging.

Prices for computer memory are skyrocketing, affecting many industries. For example, a 64GB RAM kit that cost $209 last month is now $650. Companies like Raspberry Pi are raising prices, and smaller vendors are seeing memory prices double or triple.

The rise in prices is largely due to the demand from AI datacenters, which are prioritizing RAM production for their needs, leaving consumers with fewer options. As a result, companies are stockpiling RAM, leading to shortages. This situation is reminiscent of the chip shortages in 2021-2022.

Many products, including cameras and gaming consoles, will likely see price increases due to this memory shortage. While some hope that prices will drop after the AI boom, much of the new RAM is incompatible with regular consumer devices.

Overall, this trend may hurt PC builders and hobbyists, making it a challenging time for those looking to buy new components or build systems.

No summary available.

The article discusses whether the current boom in AI datacenters is similar to the telecom crash of the early 2000s. It highlights key differences in fundamentals between the two situations.

Telecom Crash Overview:

• In the late 1990s, telecom companies overspent on infrastructure, laying down massive amounts of fiber that went largely unused due to a severe overestimation of demand.
• CEOs falsely claimed internet traffic was growing much faster than it was, leading to significant overbuilding and debt.
• Technological advancements made much of the infrastructure obsolete before it could be utilized.

AI Infrastructure Today:

• Unlike the exponential efficiency gains seen in the telecom era, improvements in AI hardware performance are slowing down, with rising power consumption and limits on semiconductor technology.
• Demand for AI is potentially underestimated. Increased usage of AI agents could lead to a significant surge in token consumption per user, creating a different demand curve compared to the telecoms.

Capital Expenditure Trends:

• The spending on datacenters is rising but is not as dramatic as it seems. Investments in AI infrastructure are being labeled as "AI," but much of it is for existing technologies.

Forecasting Challenges:

• Datacenter construction takes years, making it hard to match capacity with rapidly changing demand.
• Companies might overbuild to avoid falling behind in the competitive AI landscape, leading to potential financial stress if demand does not meet expectations.

Key Differences:

• The telecom crash involved overcapacity due to a miscalculation of demand and rapid technological obsolescence. In contrast, AI datacenters may face slower growth in supply but potentially exponential demand, with existing infrastructure remaining valuable longer.

Conclusion: While there may be a short-term correction in AI datacenters if demand doesn't match rapid investment, the article argues that the fundamentals are different from the telecom crash. Instead of building infrastructure that becomes obsolete, AI datacenters may simply experience slower utilization rates. The main risk lies in timing, not the direction of demand growth.

Summary:

The author shares a disappointing lunch meeting with a former Microsoft colleague who reacted negatively to their AI project, Wanderfugl. Instead of critiquing the product, she expressed frustration with the overall state of AI in Seattle, highlighting issues like layoffs and ineffective AI tools at work. This negativity reflects a broader sentiment among Seattle engineers, who are critical of AI, unlike those in other cities who are more curious and open.

The author notes a shift in Seattle's tech culture, where once there was optimism and room for innovation, now there’s fear and resentment, especially following layoffs and a forced reliance on poor AI tools. Engineers feel discouraged and believe they lack the skills to work on AI, which ultimately stifles creativity and progress. The author concludes that Seattle has talented engineers, but their mindset is holding them back, while places like San Francisco maintain a belief in their ability to create change.
