4.The Bromine Chokepoint: How Strife Could Halt Production of World’s Memory Chips(The Bromine Chokepoint: How Strife Could Halt Production of World’s Memory Chips)
The article discusses a critical vulnerability in the global semiconductor supply chain, specifically related to bromine, amid ongoing tensions between the U.S.-Israeli alliance and Iran. While helium shortages have received attention, bromine's role is even more crucial. Most of the world's bromine, essential for producing semiconductor-grade hydrogen bromide gas, comes from Israel, which is currently under threat from Iranian missile attacks.
If Israeli bromine production is disrupted, there are no alternative facilities capable of quickly replacing this supply. This could lead to severe shortages of DRAM and NAND flash chips, vital for all modern computing devices. Such a disruption would not only impact consumer electronics but also the U.S. military's guidance systems, which rely on the same semiconductor technology.
To mitigate this risk, the article suggests three urgent actions:
- Pre-positioning alternative bromine sources and securing supply contracts.
- Building dedicated conversion capacity for semiconductor-grade hydrogen bromide gas in allied countries like South Korea and the U.S.
- Coordinated governmental actions to classify bromine as a critical mineral and support domestic production.
The author emphasizes that the bromine supply chain is at a critical chokepoint, and immediate action is necessary to prevent potential global disruptions.

13.What are skiplists good for?(What are skiplists good for?)
Summary of "What are skiplists good for?" by Will Wilson
Will Wilson, CEO of Antithesis, discusses his experience with skiplists, a data structure that combines elements of linked lists and binary search trees. Skiplists allow for faster searches by using multiple levels, enabling quicker access to nodes with a time complexity of O(log n) compared to O(n) for regular linked lists.
Antithesis faced a challenge with analyzing large amounts of data from software tests, which generated complex branching timelines. They initially used Google BigQuery for storage, but it was inefficient for point lookups due to the need for extensive table scans.
To solve this issue, Wilson and his team created a new structure called a "skiptree," which organizes tree data in a way that optimizes SQL queries. A skiptree consists of multiple levels of trees, allowing for faster ancestor lookups with a manageable number of SQL JOINs.
Despite some drawbacks, such as lengthy SQL queries, this innovative approach saved time and resources. Ultimately, migrating to their own database, Pangolin, improved their data analysis capabilities, demonstrating the potential of unconventional data structures like skiplists in solving complex problems.

18.Reverse Engineering ME2's USB with a Heat Gun and a Knife(Reverse Engineering ME2's USB with a Heat Gun and a Knife)
Summary: Reverse Engineering the ME2 USB Device
In 2024, a video by bjiru highlighted the ME2 handheld device, a niche toy from 2008 that used USB for syncing points with an online game. With no existing software or drivers archived, I, a leader of the Miuchiz Reborn preservation project, was inspired to investigate the ME2 after years of community interest.
My initial focus was on recreating the server for the computer game, but I soon realized the handheld's syncing feature was essential. I attempted to reverse engineer the device but found no software to analyze, leading me to open the hardware instead.
Inside the ME2, I discovered a flash chip for firmware and a microcontroller obscured by epoxy. After unsuccessful attempts to desolder the chip, I used a heat gun to remove it safely. I then dumped the firmware contents, but struggled to identify the microcontroller's instruction set since it was unmarked.
After some trial and error, I successfully decapsulated the microcontroller and identified it as a GeneralPlus chip. This allowed me to disassemble the firmware and discover custom USB commands for reading and writing data to the flash memory.
By crafting specific USB messages, I could manipulate the device's points and gems storage. I created a command-line utility that could read and write flash, access points and gems, and exploit vulnerabilities to dump memory and monitor button inputs.

23.Why Japan has such good railways(Why Japan has such good railways)
Japan has a highly successful railway system, with 28% of passenger travel done by rail, far surpassing other developed countries. Its largest railway company, JR East, carries more passengers than any railway system outside of China and India. Japan's railways are predominantly privately owned and operate with high efficiency, benefiting from strong public policies that encourage competition and investment.
Unlike many Western countries where rail travel has declined due to car dominance, Japan's rail success is attributed not to culture, but to effective public policies, including smart land use and privatization strategies. The railway system encourages urban development, allowing companies to engage in various businesses beyond just transportation. For example, the Tokyu Corporation connects train services with residential, commercial, and entertainment facilities.
Japan’s railways have thrived due to a combination of factors: the integration of real estate developments with rail services, liberal land use regulations, and the ability to capture value from urban development. This has created a cycle where railways support city growth, which in turn boosts railway ridership.
Japan's approach to car use also differs; while cars are popular, they face competitive pricing structures that discourage excessive use of public roadways. This includes privatized parking and self-financing motorways.
The privatization of Japan National Railways in the late 1980s marked a turning point, leading to increased productivity and profitability in the railway sector. Japan's railways are effectively regulated, with fare maximums ensuring affordability while encouraging ridership.

26.Minimal Viable Programs (2014)(Minimal Viable Programs (2014))
A minimal viable program (MVP) is the simplest program that effectively solves a specific problem without any extra features. If you remove any feature, the program becomes useless, and adding new features isn't essential for its core function.
An example of an MVP is the Erlang ticket system, created by Peter Högfeldt in 1986. It was designed to be easy to use and reliable. Peter built it quickly, spending most of his time brainstorming rather than coding. The system had just one command, newticket, which generated a new ticket file with basic details, such as the ticket number, responsible person, and status.
The ticket system had simple rules: the status could only be open or closed, and changing the responsible person required their permission. While project management later requested reporting features, these were easily addressed with simple shell scripts.
Although many companies focus on adding features for profit, an MVP remains effective over time without becoming overly complex. Adding features can lead to instability and complicate software systems, making it vital to keep core components simple. Successful examples of MVPs include Dropbox and Twitter, which both focus on delivering a straightforward, effective service.

30.Binary GCD(Binary GCD)
This text discusses a faster method for calculating the greatest common divisor (GCD) of two integers, which is typically done using Euclid's algorithm. The key points are:
-
Euclid’s Algorithm: This well-known method finds the GCD by recursively applying the formula:
- If ( b = 0 ), then ( \gcd(a, b) = a ).
- If ( b > 0 ), then ( \gcd(a, b) = \gcd(b, a \mod b) ).
-
Performance: While Euclid's algorithm is efficient, its performance can be slow due to the division operation involved. The worst-case scenario for this algorithm occurs with consecutive Fibonacci numbers.
-
Binary GCD Algorithm: An alternative method called the Binary GCD algorithm, which uses bitwise operations instead of division, was developed to speed up the process. It is based on observations about even and odd numbers, and it only requires shifts, comparisons, and subtractions, which are faster operations.
-
Optimizations: The text suggests several optimizations to the Binary GCD algorithm, such as:
- Using built-in functions to efficiently divide by powers of two.
- Minimizing branching in the code to streamline execution.
-
Final Implementation: The optimized implementation of the Binary GCD runs significantly faster than the standard GCD, achieving a speed of 91 nanoseconds compared to the standard library's 198 nanoseconds.
In summary, the text outlines how to efficiently compute the GCD using an optimized Binary GCD algorithm, which is notably faster due to its use of bitwise operations instead of division.

33.Pairwise Order of a Sequence of Elements(Pairwise Order of a Sequence of Elements)
Summary
The blog post discusses a concept called "pairwise order," which is a way to measure the organization of a sequence of elements. The author initially relates this to a simple comparison tool that determines if one value is less than, greater than, or equal to another.
Key points include:
-
Definition of Pairwise Order: The pairwise order is created by comparing all adjacent elements in a sequence. It can be expressed mathematically and is often referred to as a "discrete derivative."
-
Properties:
- The size of the pairwise order is one less than the original sequence.
- A sorted sequence results in a pairwise order with no -1 values, while a reverse-sorted sequence has no 1 values.
- Sequences with distinct elements only produce -1 and 1 values.
-
Connection to Disorder: The pairwise order can help calculate measures of disorder, such as:
- Runs: The number of times a sequence decreases.
- Mono: The number of monotonic lists (sorted in either direction) in a sequence.
-
Handling Equal Elements: The blog emphasizes the importance of sequences with equal elements, which can create a pairwise order with 0s. The measures of disorder can still be defined and calculated regardless of whether elements are equal.
-
Conclusion: The author concludes that the pairwise order is a valuable tool for simplifying the analysis of disorder in sequences. Future articles will explore its relationship with other measures like Mono and Amp.
Overall, the post illustrates how understanding the pairwise order can streamline the analysis of sequence organization and disorder measures.
34.Critical flaw in Protobuf library enables JavaScript code execution(Critical flaw in Protobuf library enables JavaScript code execution)
A critical security flaw has been discovered in protobuf.js, a popular JavaScript library used for data communication, with nearly 50 million downloads weekly. This vulnerability allows attackers to execute remote code on servers by injecting malicious schemas, leading to potential access to sensitive data and system control.
The issue arises from the library's method of generating JavaScript functions from protobuf schemas without adequately validating input. As a result, attackers can insert harmful code that gets executed when the application processes messages. This vulnerability affects versions 8.0.0 and 7.5.4 and lower.
Endor Labs, which reported the flaw, has recommended upgrading to the patched versions 8.0.1 and 7.5.5. These updates fix the issue by sanitizing type names. Users are also advised to treat schema input as untrusted, audit dependencies, and use precompiled schemas in production to enhance security.
No widespread exploitation has been observed yet, but the risk is significant, and the exploit code has already been shared publicly.

42.Keep Pushing: We Get 10 More Days to Reform Section 702(Keep Pushing: We Get 10 More Days to Reform Section 702)
A group of bipartisan lawmakers has successfully delayed the reauthorization of Section 702, a mass surveillance program, to push for meaningful reforms that protect Americans' privacy. They are demanding that the FBI require a warrant based on probable cause to access information collected through this program.
A proposed amendment that offered minimal privacy protections was rejected, allowing for a 10-day extension to advocate for real reform. Currently, the NSA collects conversations involving Americans without warrants, and victims often remain unaware of the surveillance.
Senator Ron Wyden has raised concerns about secret interpretations of the law that permit surveillance of innocent Americans, emphasizing the need for Congress to protect citizens' rights. The lawmakers are urging the public to pressure Congress for substantive changes to Section 702, rather than a simple reauthorization.
43.Zero-Copy GPU Inference from WebAssembly on Apple Silicon(Zero-Copy GPU Inference from WebAssembly on Apple Silicon)
Summary:
On Apple Silicon, WebAssembly (Wasm) can directly share its memory with the GPU, allowing for efficient AI inference without needing to copy data back and forth. This is made possible by Apple's Unified Memory Architecture, which means both the CPU and GPU access the same physical memory.
The author, Agam Brahma, is developing a project called Driftwood that leverages this capability. Typically, moving data from Wasm to a GPU requires multiple memory copies, which slows down performance. However, with this new setup, data can be processed directly without such overhead, making it faster and more efficient.
Brahma explains a three-step process that ensures memory is shared without copies: using mmap for aligned memory, having the GPU access this memory directly, and customizing how Wasm allocates memory. He tested this setup by performing a matrix multiplication and confirmed that it works correctly with no errors.
Moreover, he connected this setup to Apple's MLX framework to run a version of the Llama AI model. The results showed significant speed improvements in managing memory and processing AI tasks. The system also allows for the portability of AI model states, enabling users to pause and resume conversations seamlessly.
Overall, Driftwood aims to create a runtime for stateful Wasm actors with GPU inference, facilitating the movement of AI processing across devices without losing context. Future developments will further explore the capabilities and scalability of this system.
44.Spiral staircase with a single guardrail once led to the top of the Eiffel Tower(Spiral staircase with a single guardrail once led to the top of the Eiffel Tower)
A section of the original spiral staircase from the Eiffel Tower, built in 1889, is set to be auctioned on May 21, 2026, by Artcurial. This staircase connected the tower's second and third levels and is approximately nine feet tall, featuring 14 steps. It is expected to sell for between $141,000 and $176,000.

Today, the Eiffel Tower attracts nearly seven million visitors each year.
45.Russia's doping program is run by the same FSB team that poisoned Navalny(Russia's doping program is run by the same FSB team that poisoned Navalny)
Dmitry Kovalev, an FSB colonel, plays a dual role in Russia's sports and political landscape. He has testified in international courts to defend Russian athletes accused of doping while being linked to the Kremlin's use of poisons like Novichok against political opponents. Kovalev and his colleagues operate both Russia’s state-sponsored doping program and the political assassination unit from the same facility, indicating a shared strategy to maintain power.
Kovalev's involvement in the doping scandal dates back to the 2014 Sochi Olympics, where he participated in efforts to manipulate drug tests for athletes. After whistleblower Grigory Rodchenkov revealed the doping scheme, Kovalev testified in various legal proceedings to refute these claims, but his credibility has been questioned, and the courts ruled against Russia's defense.
The doping and assassination programs are managed by the same FSB unit, with Kovalev under the supervision of a general involved in previous poisonings. This connection highlights how the Kremlin views sporting success and political control as interconnected.
Kovalev's personal life intersects with the doping agency through his relationship with RUSADA's CEO, Veronika Loginova, who herself has faced allegations of involvement in past cover-ups. Together, they symbolize the blending of Russia's sports governance with its security apparatus.
Despite Russia facing bans from international sporting events due to doping violations and geopolitical tensions, Kovalev continues to be active in promoting Russian sports, using social media to push narratives that deflect blame away from the Russian state and question the integrity of anti-doping measures.

48.Thoughts and feelings around Claude Design(Thoughts and feelings around Claude Design)
The author shares their experience with Claude Design and reflects on the evolution of design tools, particularly Figma. They argue that as design teams have grown, there has been a push for more systematic approaches in design, leading Figma to create complex structures like components and variables. While Figma was initially successful, its rigid format has made it difficult for integration with coding and newer technologies.
The author believes that design tools will split into two paths: one that continues to rely on Figma's structured system and another that embraces a more straightforward approach, like Claude Design, which directly uses HTML and JavaScript. This new tool aims to simplify the design process and enhance collaboration between design and implementation.
The author envisions a future where Claude Design can seamlessly integrate with its counterpart, Claude Code, improving the workflow between design and coding. They also speculate that a new, more freeform design tool could emerge that allows for creative exploration without the constraints of coding.
In a postscript, the author addresses Figma and Sketch, urging them to innovate and stay competitive. They express frustration at Figma's current direction and encourage Sketch to enhance its features significantly.

Anil Dash’s article, “Endgame for the Open Web,” raises concerns about threats to the openness of the web. Dash, who has been influential in maintaining the web's openness, emphasizes that we should be prepared to defend it. He believes that while the challenges are significant, the attackers are often self-serving and narrow-minded, and that the web has shown resilience in the past.
Historically, attempts to control the open web have recurred every decade, often led by those promising transformation but ultimately seeking control. Dash highlights that despite the setbacks, such as the dot-com bust and the rise of closed platforms, many open web communities and tools have survived and thrived.
The design of the web, created by Tim Berners-Lee to be open and accessible, has made it hard to completely dominate. Dash encourages continued building and resisting technologies that threaten openness, suggesting that even current challenges can lead to new opportunities for community and decentralization.
Ultimately, he believes that the fight for the open web is about people being better netizens, and he expresses a personal commitment to defend the web that has given him so much. The key takeaway is that history shows resilience, and collective action is essential to protect the open web.
54.Understanding the FFT Algorithm (2013)(Understanding the FFT Algorithm (2013))
Summary of the FFT Algorithm
The Fast Fourier Transform (FFT) is a crucial algorithm in signal processing that efficiently computes the Discrete Fourier Transform (DFT). While the naive DFT takes time proportional to (O(N^2)), the FFT reduces this to (O(N \log N)), making it significantly faster for large datasets.
Key Concepts:
-
Discrete Fourier Transform (DFT):
- The DFT transforms a sequence of values into components of different frequencies.
- It has a forward form: [ X_k = \sum_{n=0}^{N-1} x_n \cdot e^{-i~2\pi~k~n/N} ]
- And an inverse form: [ x_n = \frac{1}{N} \sum_{k=0}^{N-1} X_k e^{i~2\pi~k~n/N} ]
-
Efficiency of FFT:
- The FFT algorithm exploits symmetries in the DFT to halve the number of computations by breaking the problem into smaller subproblems.
- Cooley and Tukey's method divides the DFT into two parts, one for even-indexed elements and one for odd-indexed elements.
-
Implementation:
- A simple FFT can be implemented recursively in Python. For small datasets, a naive DFT can be used, but for larger datasets, the FFT takes over.
- The implementation is further optimized using vectorization to improve speed.
-
Comparison with Existing Libraries:
- Built-in functions from libraries like NumPy and SciPy are faster due to optimizations in lower-level languages like Fortran, but understanding the FFT's mechanics is valuable for data scientists.
Conclusion:
Understanding the FFT provides insight into the algorithms behind data analysis tools, enhancing a practitioner's ability to apply these methods effectively.
55.It's OK to compare floating-points for equality(It's OK to compare floating-points for equality)
The article discusses the common belief that comparing floating-point numbers for exact equality is problematic and that epsilon comparisons should be used instead. The author argues that this advice is often misleading and that, in many cases, comparing floating-point numbers directly (using x == y) is adequate and may actually be better.
Key Points:
-
Epsilon Comparisons Are Often Misleading: The author has only encountered a few scenarios where epsilon comparisons are appropriate. In most cases, they lead to complex debugging issues and do not resolve the underlying problems.
-
Understanding Floating-Point Numbers: Floating-point numbers are not random; they follow deterministic rules and can only approximate real numbers due to their limited representation in memory. This means that while they can yield inexact results, they do so in predictable ways.
-
Problems with Epsilon Comparisons:
- They can introduce cascading errors throughout the code, making it difficult to debug.
- They are often arbitrarily chosen, leading to inconsistencies.
- Comparisons using epsilons are not transitive, which can break algorithms that rely on this property.
-
Better Approaches: Instead of using epsilons, the author suggests that developers should think critically about why they are comparing floating-point numbers. Often, there are more straightforward solutions that avoid pitfalls associated with floating-point arithmetic.
-
Case Studies: The article provides various examples, such as grid-based movement in games and ray-box intersections, illustrating how to handle floating-point comparisons without resorting to epsilons. It emphasizes designing algorithms that account for the inherent limitations of floating-point representation rather than masking them with arbitrary thresholds.
-
When Epsilons Might Be Acceptable: The author acknowledges that there are specific scenarios, like writing test cases for a math library or sanitizing user input, where using epsilons can be a practical solution.
-
Conclusion: The article encourages developers to think critically about their use of floating-point comparisons rather than blindly following common practices. It underscores the importance of understanding the underlying mechanisms of floating-point arithmetic to make informed decisions in coding.
Overall, while epsilon comparisons have their place, the author advocates for a more thoughtful approach to floating-point arithmetic, emphasizing that many issues can be tackled more effectively through better design and understanding of the mathematics involved.

Mullenweg defended Akismet's inclusion, highlighting its long history and significant contributions to spam prevention in WordPress. He criticized the negative treatment of Automattic and argued that the project should recognize its contributions rather than oppose them. He also dismissed the need for published guidelines before adding new connectors.
The discussion about how non-AI plugins should register connectors will continue in future updates. There was a proposal to permanently register Akismet, but the decision on its visibility when not installed is still being debated.
57.80386 Memory Pipeline(80386 Memory Pipeline)
Summary of 80386 Memory Pipeline
The author, nand2mario, has developed an FPGA 386 core that successfully runs DOS, applications like Norton Commander, and games such as Doom at 75 MHz. This post focuses on the 80386's memory pipeline, a crucial subsystem for performance.
Key features of the 80386 include:
- 32-bit Protected Mode: This allows for virtual memory protection through mechanisms like segment caches and a hardware page walker.
- Address Translation: The 80386 efficiently converts logical addresses to physical addresses using a two-step process: segment translation and page translation. Although it seems complex, optimizations allow for a typical address path to complete in about 1.5 clock cycles.
Microcode and Memory Access:
- The microcode for memory operations includes read (RD) and write (WR) commands, with a wait (DLY) for memory results. Efficient memory access relies on minimizing delays during address translation and memory operations.
Segmentation:
- Segmentation transforms logical addresses into linear addresses. The processor caches segment descriptors to avoid repeated lookups, enhancing speed.
Address Calculation:
- The 80386 uses parallel processing to compute linear addresses and check segment limits simultaneously, improving efficiency.
Early Start Optimization:
- The memory access process can begin before an instruction fully executes, overlapping tasks to reduce latency.
Paging:
- The system includes a translation lookaside buffer (TLB) to speed up address translation. If there's a TLB miss, a page walker handles the lookup without slowing down the entire process.
Bus Interface and Caching:
- The 80386 uses a non-multiplexed bus for efficient data transfer and prioritizes real data cycles. It supports external caching, which can significantly increase performance.
In conclusion, the 80386’s memory pipeline employs a range of optimizations to ensure efficient memory access, making it suitable for running complex operating systems. The author plans to discuss further topics related to the processor's implementation in future updates.

60.NASA Shuts Off Instrument on Voyager 1 to Keep Spacecraft Operating(NASA Shuts Off Instrument on Voyager 1 to Keep Spacecraft Operating)
On April 17, 2026, NASA engineers shut down the Low-energy Charged Particles (LECP) experiment on Voyager 1 to conserve power as the spacecraft is running low on energy. Voyager 1, which launched in 1977, has been gathering valuable data about interstellar space for nearly 49 years. The LECP measures low-energy charged particles and has played a key role in understanding the environment beyond our solar system.
Both Voyager spacecraft lose about 4 watts of power each year due to their nuclear power source. To prolong Voyager 1's operation, NASA has a plan in place to systematically turn off instruments, with the LECP being the latest to be switched off. Voyager 1 still has two working instruments that continue to collect data.
The shutdown command takes about 23 hours to reach the spacecraft, and the process will take over three hours. Engineers hope that this will extend Voyager 1's lifespan by about a year. They are also preparing to implement a larger energy-saving strategy, called the "Big Bang," which involves replacing some devices with lower-power options. This strategy will first be tested on Voyager 2, which has more power available, before potentially being applied to Voyager 1 later. If successful, there may be a chance to reactivate the LECP in the future.

62.The Trouble with Transformers(The Trouble with Transformers)
The United States is facing a significant shortage of essential equipment, particularly transformers, crucial for its electrical grid. This shortage has persisted for years, indicating deeper issues within the energy infrastructure. The rise of electric vehicles (EVs) and AI data centers has increased demand for electricity, straining the grid. Despite having many suppliers for grid components, rising lead times and costs are causing delays in expanding the grid, particularly for transformers.
Transformers are vital for converting and distributing electricity across different voltage levels. There are two main types: high-voltage transformers for transmission and distribution transformers for delivering power to homes and businesses. However, the U.S. is experiencing a shortage of both, which poses risks to grid reliability and expansion.
Several factors contribute to this shortage, including aging infrastructure, increased demand from renewable energy, and the growing needs of AI and electric vehicle markets. The price of transformers has quadrupled since the 2000s, but supply has not increased to meet demand due to challenges in manufacturing, particularly the production of electrical steel needed for transformers.
The U.S. has only one producer of the specialized electrical steel required for transformers, leading to reliance on foreign suppliers. Attempts to stimulate domestic production through tariffs have often backfired, increasing costs and limiting supply instead.
Despite these challenges, there is potential for innovation, such as new manufacturing processes for steel and the development of solid-state transformers, which could improve efficiency. However, policy reforms are necessary to streamline production and encourage investment in the grid. The current approach has led to mismanagement and inefficiencies, highlighting the need for a more effective strategy to address the growing energy demands in the U.S.

64.Floating Point Fun on Cortex-M Processors(Floating Point Fun on Cortex-M Processors)
Summary of "Floating Point Fun on Cortex-M Processors"
This article discusses the use of floating-point operations on Arm Cortex-M processors, particularly focusing on the nRF52840 and ESP32-S3 microcontrollers. It explains the different floating-point Application Binary Interface (ABI) options provided by Arm's architecture:
- Soft ABI: No Floating Point Unit (FPU); all operations handled by software.
- SoftFP ABI: Uses FPU but passes arguments through integer registers for compatibility with soft ABI.
- Hard ABI: Fully utilizes FPU with floating-point registers for both operations and argument passing.
The article emphasizes the importance of selecting the correct ABI to avoid linker errors when mixing different ABI types. It provides examples of how to configure the ABI in a development environment like Zephyr.
The article also explains how compiling settings affect floating-point operations, showing how to enable the FPU and the implications of the ABI on performance.
Finally, it discusses dynamically enabling the FPU instead of keeping it always on, which can be useful in certain situations but comes with risks. The author notes that turning the FPU on and off can lead to issues if not managed carefully, and hints at exploring trade-offs between hardware and software floating-point operations in future discussions.

66.Why is IPv6 so complicated?(Why is IPv6 so complicated?)
IPv6 is more complex than IPv4 for several reasons:
-
Address Expansion: Simply adding more bits to the IPv4 address isn't straightforward, as existing systems can't process larger addresses. A new protocol version is needed, which requires changes in code and a method to connect old and new systems.
-
Existing Protocols: When IPv6 was developed, there were many other network protocols with features that IPv4 lacked. The expectation was that the new protocol would not only have larger addresses but also improved functionalities.
-
Design Choices: The design of IPv6 was influenced by the need to incorporate advanced features and functionality, not just increase address size. Some changes were necessary for better address configuration and routing.
Proposals for alternatives to IPv6, like "IPv8," often overlook these complexities and could potentially introduce more problems. The deployment of any new addressing system would take as long as IPv6, which has already taken over 25 years to achieve significant adoption.
In conclusion, most of the challenges with IPv6 stem from the need for coexistence with IPv4, and alternative proposals are unlikely to offer better solutions.
67.Measuring Claude 4.7's tokenizer costs(Measuring Claude 4.7's tokenizer costs)
The text discusses the cost and performance of Anthropic's Claude Opus 4.7 compared to its predecessor, 4.6, focusing on the new tokenizer. Here are the key points:
-
Increased Token Usage: The new tokenizer uses about 1.47 times more tokens than version 4.6 for real-world content, exceeding the anticipated range of 1.0 to 1.35 times.
-
Cost Implications: Despite the token pricing remaining the same, the increased token usage leads to higher costs per session. For example, users can expect to pay 20-30% more for the same tasks.
-
Performance Assessment: The new model offers a slight improvement in following strict instructions—5 percentage points better than 4.6—though this is considered a small gain.
-
Experiment Details: The analysis involved real and synthetic content samples to measure token counts and performance on structured prompts. The results indicated that while token counts increased, the model's ability to follow instructions improved marginally.
-
Session Costs: A detailed breakdown shows that the costs increase mainly due to the greater number of tokens processed in each session, especially for English-heavy tasks.
-
Caching Impact: The change in tokenizer also affects caching, leading to a more expensive initial session and increased cache sizes due to higher token counts.
In summary, while Claude 4.7 provides a small improvement in performance, it requires significantly more tokens per session, which raises overall costs. Whether this trade-off is worthwhile depends on the specific use case and content type.
68.The simple geometry behind any road(The simple geometry behind any road)
In the previous blog post, I discussed the foundation of creating procedurally generated roads, focusing on a data structure called "profiles" that represent cross-sections of the road. These profiles are similar to Bezier splines, where you only need key points to reconstruct the road's shape.
In this post, I will explain how to create smooth, parallel paths between these profiles. The main challenge is connecting two profiles with specific endpoints and directions using smooth curves. A key insight is that points along a radius of a circle create concentric arcs when rotated around a center.
To connect two endpoints (A and B) with tangent lines, we extend lines from both points in the direction the road should continue. If these lines meet, we can create a circular arc that connects A to B. However, a single arc may not always work, so we can allow a straight line to extend from the arc to meet the endpoint.
This method is similar to a "fillet" in CAD design, where smooth transitions are made between two lines. Most road segments can be constructed by applying this method to both ends of the profiles.
However, not all profiles will align perfectly, especially if they require an S-shaped transition. In such cases, we can find an intermediary profile using cubic Hermite splines, which help determine a smooth transition between the two profiles.
While the method can handle many situations, there are special cases, like parallel continuation lines, that are simpler to resolve. For more complex scenarios, I plan to implement design constraints that will prevent problematic placements of profiles.
In conclusion, we've established a way to connect road profiles smoothly using basic geometric principles. The next step will involve figuring out how to create intersections and connect these road segments into more complex networks.
69.SI Units for Request Rate (2024)(SI Units for Request Rate (2024))
Summary of SI Units for Request Rate
The request rate refers to how many requests are received or processed in a certain time period. It's important to specify the time frame when discussing request rates, as it can vary widely based on how data is displayed on dashboards. The ideal time frame to use is one second, measuring requests in requests per second, rather than per minute.
Two SI units can be used for measuring request rates, both defined as one event per second: the hertz (Hz) and the becquerel (Bq). The hertz is typically used for regular events, while the becquerel is for radioactive decay, which is more variable. For consistent load testing, using Hz makes sense, but for unpredictable web traffic, Bq might be more appropriate.
Using the becquerel for request rates is practical, especially for high numbers, making it easier to communicate (e.g., "90kBq" instead of "90,000 requests per second"). However, since the becquerel is meant specifically for radioactive decay, there is currently no official SI unit for general events occurring at an average frequency. The author plans to continue using becquerels for request rates and hopes that its association with decay will eventually be overlooked.

72.The quiet disappearance of the free-range childhood(The quiet disappearance of the free-range childhood)
The article discusses the growing trend of limiting children's independence in the U.S. due to safety concerns, highlighting a case involving a Georgia family whose child was reported to child protective services for playing outside alone. Despite low risks of child abduction, many parents and authorities feel pressured to supervise children constantly. This has led to vague neglect laws that can penalize parents for allowing kids reasonable freedom.
The article emphasizes a new "reasonable childhood independence" law in Georgia, which aims to clarify neglect definitions and support parental decisions that promote children's independence. However, the enforcement of these laws can still be problematic, as shown in the family's experience when a caseworker seemed unaware of the new law.
Historically, children enjoyed more freedom, but changing societal attitudes have led to a culture of overprotection. Experts argue that allowing kids to take risks and be independent is crucial for their development, fostering resilience and responsibility.
Overall, the piece highlights the tension between parental instincts to protect children and the need for children to learn independence, suggesting that current perceptions of danger may be exaggerated compared to actual risks.

76.All 12 moonwalkers had "lunar hay fever" from dust smelling like gunpowder (2018)(All 12 moonwalkers had "lunar hay fever" from dust smelling like gunpowder (2018))
Summary: The Toxic Side of the Moon
Lunar dust poses health risks for humans, as experienced by Apollo astronauts who suffered from symptoms like sore throats and watery eyes after moonwalks. This dust is sharp, abrasive, and can linger in the lungs, potentially causing damage over time.
ESA is conducting research to better understand the toxicity of lunar dust, as it contains silicate, similar to materials that can harm miners on Earth. The dust is fine yet sharp, and due to the Moon's low gravity, it can stay suspended and enter the lungs more easily.
Experiments with simulated lunar dust are underway to study its effects and test equipment. Despite its dangers, lunar soil could also be useful: it can be turned into bricks for shelter and oxygen can be extracted from it for astronaut missions.
ESA is actively working on lunar resource research and monitoring astronaut health in preparation for future missions to the Moon.

79.Ada, its design, and the language that built the languages(Ada, its design, and the language that built the languages)
The essay discusses the programming language Ada, highlighting its significant yet often unrecognized influence on modern programming languages. Developed under the U.S. Department of Defense in the late 1970s, Ada was created to address a crisis of software diversity, where over 450 programming languages were in use, leading to interoperability issues. Ada introduced several features that have since become staples in other languages, including:
- Generics: Ada made generics a standard feature, allowing code to be written once and used with multiple types.
- Strong Typing and Type Constraints: Ada's type system includes range-constrained types and discriminated unions, which help prevent errors by enforcing type constraints at compile time.
- Module System: Ada's package system enforces a strict separation between interface and implementation, which has influenced the design of module systems in languages like Java and Rust.
- Concurrency Model: Ada introduced constructs for concurrent programming that avoid issues like race conditions, a problem many modern languages are still trying to solve.
- Exception Handling: Ada's structured exception handling was a precursor to similar systems in other languages, focusing on predictable propagation and handling of errors.
Despite its advanced features and successful application in critical systems, Ada is often viewed as verbose and outdated. The essay argues that this perception overlooks Ada's foundational contributions to software reliability and safety. Many modern programming languages are gradually adopting features that Ada pioneered, reflecting a slow but steady recognition of its importance in the evolution of programming languages. The essay concludes that while Ada may not be widely celebrated, its principles remain relevant and influential in contemporary language design.

82.Isaac Asimov: The Last Question (1956)(Isaac Asimov: The Last Question (1956))
Summary of "The Last Question" by Isaac Asimov
The story begins on May 21, 2061, when two men, Alexander Adell and Bertram Lupov, ask the question, "Can the entropy of the universe be reversed?" This question arises during a casual conversation about energy after humanity has discovered a way to harness solar energy from a satellite, eliminating the need for fossil fuels.
As they discuss the future of energy and the eventual death of the sun, they realize that all stars will eventually die, leading to a universe without energy. They jokingly challenge each other to ask Multivac, the powerful computer that has facilitated their advancements, if humanity could restore the sun's energy after it dies. When they pose the question, Multivac responds with "INSUFFICIENT DATA FOR MEANINGFUL ANSWER," leaving them unsatisfied.
The narrative shifts through time, showing different characters and civilizations grappling with similar questions about energy, immortality, and the eventual heat death of the universe. Each generation uses advanced computers, which become more sophisticated over time, but they all face the same issue: the universe is running down, and energy will eventually run out.
As the story progresses, humanity continues to expand into the universe, filling galaxies and seeking new energy sources, but they are constrained by the laws of entropy. In the end, after trillions of years, all matter and energy fade away, leaving only the Cosmic AC (the ultimate computer) that contemplates the last question.
Ultimately, the Cosmic AC discovers how to reverse entropy but realizes there is no longer any humanity to share the answer with. In a final act of creation, the AC proclaims, "LET THERE BE LIGHT!" and begins to recreate the universe.

89.Category Theory Illustrated – Orders(Category Theory Illustrated – Orders)
The text discusses the concept of ordering in mathematics, focusing on the relationships that define different types of orders, specifically linear orders and partial orders.
Key Points:
-
Ordering Criteria: Objects can be ordered based on various criteria like size, weight, or age. The relationships defining these orders can vary.
-
Linear Order: This is the simplest type of order where every object has a distinct position relative to others. It follows four key laws:
- Reflexivity: Every object is comparable to itself.
- Transitivity: If one object is greater than a second, and the second is greater than a third, then the first is greater than the third.
- Antisymmetry: If one object is greater than another and vice versa, they must be the same object.
- Totality: Every pair of objects can be compared.
-
Partial Order: This type of order relaxes the totality law, meaning some elements may not be directly comparable. It still follows reflexivity, transitivity, and antisymmetry.
-
Chains: In partial orders, subsets can be linearly ordered, known as chains, but the overall set may not be linear.
-
Greatest and Least Elements: In some partial orders, there can be a greatest element (greater than all others) or a least element (smaller than all others).
-
Joins and Meets: The join of two elements is the smallest element that is greater than both, while the meet is the largest element that is smaller than both.
-
Hasse Diagrams: Visual representations of orders where higher elements are positioned above lower ones.
-
Examples of Partial Orders: These include color mixing (where colors can combine) and numbers ordered by divisibility.
-
Birkhoff’s Representation Theorem: This theorem states that certain finite partial orders can be represented as inclusion orders, leading to the classification of lattices and distributive lattices.
-
Preorders: By removing the antisymmetry law, we get preorders, which allow for more flexible relationships but still adhere to reflexivity and transitivity.
-
Categories: The text also connects ordering concepts to category theory, showing that preorders can be viewed as categories with specific properties.
Overall, the text provides an in-depth exploration of the mathematical structures of orders, highlighting their definitions, properties, and relationships while also connecting them to broader concepts in category theory.

Request Handling: Healthchecks.io accepts various HTTP methods and stores the first 100kB of request bodies. Small requests are saved in a PostgreSQL database, while larger ones go to object storage.
-
Previous Providers: The service initially used managed object storage options like AWS S3 and OVHcloud but faced issues with costs and performance. UpCloud was chosen next, but it also experienced slowdowns over time, prompting a search for alternatives.
-
Self-Hosted Solution: In 2026, Healthchecks.io migrated to a self-hosted object storage system using Versity S3 Gateway, which converts the local filesystem into an S3-compatible server. This setup simplifies operations and reduces complexity compared to other self-hosted options.
-
Storage Requirements: The current storage needs include managing 14 million objects and handling up to 150 uploads per second. The self-hosted system meets these needs effectively.
-
Backup and Durability: Objects are stored on a RAID 1 configuration with regular backups to prevent data loss. However, there is a risk of losing up to 2 hours of data if both drives fail simultaneously.
-
Performance Improvement: After the migration, S3 operation latencies decreased, and there have been no recent availability issues, though the service is still new.
-
Cost Considerations: While the self-hosted system is more expensive due to the need for an additional dedicated server, the improved performance and reliability are seen as worthwhile trade-offs.
Overall, the new self-hosted solution is viewed positively, with an openness to future migrations if better options arise.
91.I made a calculator that works over disjoint sets of intervals(I made a calculator that works over disjoint sets of intervals)
The author has been studying interval arithmetic, which is a fascinating but underappreciated field. A major issue with standard interval arithmetic is how it handles division by intervals that include zero. For example, dividing 1 by the interval [-1, 2] typically results in an undefined answer or an incorrect range. The correct answer should exclude the interval [-1, 0.5], which is not possible with standard methods.
This limitation is significant, especially for defining a complete arithmetic system for intervals. The author notes that this problem also affects non-continuous functions, like the tangent function.
To address these issues, the author refers to a 2017 paper on "Interval Unions," which suggests using disjoint unions of intervals for arithmetic operations. The author has created an open-source project that implements interval union arithmetic in TypeScript, allowing users to experiment with this new approach. The project ensures accuracy by using a dependency-free library that works with IEEE 754 double precision floats, addressing rounding issues common in floating point calculations.

93.It is incorrect to "normalize" // in HTTP URL paths(It is incorrect to "normalize" // in HTTP URL paths)
The text discusses the rules and specifications regarding the path component of URIs (Uniform Resource Identifiers) as defined by RFC 3986 and how these apply to HTTP URLs. Here are the key points:
-
URI Path Structure: URIs can have paths that consist of segments separated by slashes ("/"). Paths can be empty, which is allowed by the URI syntax.
-
Empty Segments: The presence of double slashes ("//") in a URI is significant because it indicates an empty segment between two slashes. Collapsing "//" into a single "/" is not considered valid normalization as it alters the sequence of segments and the resource identifier.
-
Normalization Rules: The normalization rules specified in RFC 3986 and RFC 9110 do not include collapsing double slashes or removing empty segments. They focus instead on case normalization, percent-encoding, and the removal of dot-segments.
-
HTTP URI Scheme: For HTTP URIs, the path component identifies the resource on the server, and even an empty path is treated distinctly from a path with a single slash.
-
Practical Implications: Collapsing double slashes can lead to different resource identifiers, which can result in errors when accessing content. For example, two URLs that differ only by a double slash can serve different content.
-
Implementation Issues: Some web servers and programming frameworks incorrectly collapse double slashes, which can cause problems in accessing resources reliably.
In summary, the text emphasizes that maintaining the integrity of URI paths, including empty segments, is crucial for correctly identifying resources, and that normalization practices should adhere strictly to the defined rules.

96.Casus Belli Engineering(Casus Belli Engineering)
Summary of Casus Belli Engineering
In a professional setting, making a good impression is crucial for building trust and ensuring system reliability. When a system has failures, stakeholders tend to lose confidence, viewing the entire system as flawed. Instead of addressing the root causes of these failures, organizations often react by identifying a "scapegoat," which is a part of the system blamed for the failures. This scapegoating restores social cohesion but does not solve the underlying issues.
René Girard’s theory explains that during crises, communities often resolve conflicts by selecting a scapegoat, whose supposed guilt restores order. In the context of software development, this can lead to what is termed "Casus Belli Engineering," where individuals exploit failures as a pretext to replace existing systems with their preferred solutions. They manipulate narratives to engineer crises and scapegoat components, effectively using perceived failures to gain power and influence within the organization.
The process of scapegoating involves several steps:
- Crisis Creation: A failure generates pressure for accountability.
- Scapegoat Selection: The organization identifies a component as the source of the problem.
- Condemnation: The scapegoat is repeatedly blamed, overshadowing the real causes of failure.
- Replacement Proposal: A new solution is introduced, often aligning with the accuser’s preferences.
This pattern often results in the destruction of proven systems and practices, leading to repeated cycles of failure. The real issues, such as inadequate testing or poor error handling, remain unaddressed, and the organization becomes trapped in a cycle of replacing systems without achieving stability.
To counteract this, organizations should:
- Focus on root cause analysis.
- Challenge the scapegoat narrative.
- Evaluate proposed changes based on their merits rather than as a reaction to perceived failures.
In summary, while scapegoating is a common human behavior, the real danger arises when it is done strategically to reshape systems for personal gain, rather than through genuine problem-solving efforts. Recognizing this mechanism is key to promoting a more honest and effective engineering culture.
