3.Fast Allocations in Ruby 3.5(Fast Allocations in Ruby 3.5)
Fast Allocations in Ruby 3.5
In Ruby 3.5, allocating objects is set to be significantly faster—up to six times faster than in earlier versions. This article discusses the improvements and how they were achieved.
Key Points:
-
Benchmarking: The performance of object allocation is measured using different types of parameters (positional and keyword) and with or without YJIT (Yet another Just-in-Time compiler). The benchmarks show how performance changes with the number of parameters.
-
Results: All types of allocations in Ruby 3.5 are faster than in Ruby 3.4.2. For positional parameters, the speedup is constant—about 1.8 times faster without YJIT and 2.3 times faster with YJIT. Keyword parameters benefit more from the improvements; with three keyword parameters, Ruby 3.5 is three times faster, and with YJIT, over six times faster.
-
Optimization Focus: The main goal was to speed up the
Class#new
method, which creates new instances of classes. The method was slow due to the overhead of calling other methods and the way parameters were passed. -
Calling Conventions: Ruby uses a stack for passing parameters, but calling C functions from Ruby requires converting parameters, adding overhead. The new optimization reduces this overhead by improving the way parameters are handled.
-
Inlining: Instead of implementing
Class#new
in Ruby, an inline version was created directly in the YARV (Yet Another Ruby VM) to remove unnecessary method calls. This reduces the need for memory copies and improves cache hit rates for method calls. -
Downsides: While the optimization increases speed, it also slightly increases memory usage and introduces a minor backward incompatibility in how call stacks are displayed.
Conclusion: The optimizations in Ruby 3.5 will greatly enhance performance in object allocation, making Ruby applications faster and more efficient. The author expresses excitement for the upcoming release and encourages further exploration of the changes.
4.Adventures in Symbolic Algebra with Model Context Protocol(Adventures in Symbolic Algebra with Model Context Protocol)
The text discusses the MCP (Model Context Protocol), a new tool developed by Anthropic that allows AI language models to interact with external tools, similar to how USB-C standardizes connections. MCP is still in its early stages and has some security concerns since it runs locally and can execute arbitrary code.
The author experimented with MCP to help language models perform complex mathematical tasks, particularly in tensor calculus, where they often struggle. The idea is to connect these models with specialized computer algebra systems like Mathematica and Sympy, allowing each to do what they excel at—language models for understanding and planning, and algebra systems for precise calculations.
The MCP environment is described as somewhat chaotic, with unclear documentation and debugging challenges. However, it has the potential to significantly enhance the capabilities of language models in mathematical contexts by allowing them to delegate complex calculations to more reliable systems.
An example is provided, demonstrating how a language model can solve a differential equation by using Sympy to compute the correct solution instead of generating incorrect ones. The author encourages others to try out MCP but warns about potential security risks associated with running unverified code. Instructions for installation are included, emphasizing caution when setting it up.
5.Planetfall(Planetfall)
Summary of "Planetfall" by Daniel Huffman
Daniel Huffman shares his latest project, a detailed map of the fictional planet Chiron from the cult classic computer game Alpha Centauri. This project has been one of the most challenging in his career, requiring extensive technical skills.
Huffman discusses the difference between mapping real and fictional places, noting that his expertise lies in real-world cartography. However, he was able to create this fictional map using existing game data, as the game provides detailed attributes like elevation and rainfall for each pixel on the map.
The process involved meticulous data gathering, including recording elevation values for all 8,192 tiles on the map and creating thematic maps for rainfall and rockiness. He used software like QGIS for data manipulation and interpolation techniques to enhance the resolution of the elevation model, ultimately achieving a more organic-looking terrain.
Huffman explains how he applied a cylindrical equal-area projection to represent the planet accurately, adjusting various parameters for visual appeal. He also detailed the artistic aspects of the mapping process, including colorization, vegetation representation, and river design, all while ensuring the final map reflects the game's aesthetic.
The project highlights the labor-intensive nature of cartography, especially when creating a map from a fictional source. Huffman expresses his excitement about the final product and invites support from those interested in his work.
In conclusion, this map serves as a tribute to Alpha Centauri, showcasing Huffman's journey as a cartographer while merging technical skills with creative design.
6.Gemini Diffusion(Gemini Diffusion)
Google recently announced Gemini Diffusion, its first language model (LLM) that uses a diffusion approach instead of the traditional transformer method. Here are the key points:
-
Diffusion vs. Traditional Models: Traditional models generate text one word at a time, which can be slow and affect output quality. In contrast, diffusion models generate text by refining noise step-by-step, allowing for faster and more accurate results.
-
Speed: Gemini Diffusion is notably fast, capable of generating text at 857 tokens per second. For example, it can create an interactive HTML and JavaScript page in just a few seconds.
-
Performance Comparison: While independent benchmarks are not available yet, Google claims that Gemini Diffusion performs at "5x the speed" of its Gemini 2.0 Flash-Lite model, suggesting it is quite powerful.
-
Clarification on Technology: Some confusion exists about diffusion models. They don't completely replace transformers but use a different method for generating text that involves processing inputs all at once, similar to BERT's approach.
-
Training Method: Diffusion models build on the idea of filling in masked tokens in a sentence, progressively generating text by refining guesses over several iterations, which makes them efficient at output generation.
In summary, Gemini Diffusion is a new, fast language model by Google that uses a unique approach to text generation, promising improved speed and quality.
7.The scientific “unit” we call the decibel(The scientific “unit” we call the decibel)
The author expresses frustration with the concept of decibels (dB), explaining that they are not a standard unit of measurement but rather a way to indicate changes in magnitude, similar to prefixes like "mega-". A decibel is based on a logarithmic scale, originally derived from the "bel," which measures power changes.
The bel was later divided into decibels for convenience, leading to irrational multipliers for different units like power and voltage. This creates confusion, as the meaning of a decibel can vary greatly depending on the context and reference point, often leaving users uncertain about what is being measured.
In acoustics, for instance, dB is often based on sound pressure, but this isn’t always clear. Additionally, specifications for devices like microphones can lead to misunderstandings about the reference levels being used. The author highlights the complexity and inconsistency in the usage of decibels, making them a source of confusion in scientific and technical fields.
8.Four years of sight reading practice(Four years of sight reading practice)
The author has been practicing sight reading on the piano using an iPad app called "NoteVision" for four years. They started playing guitar in the 1990s and began learning piano when their family acquired a piano in 2021. The author uses a MIDI keyboard and a Bluetooth connection to the app, which provides fast feedback and allows customization of practice settings.
They created a Python app to streamline their practice, tracking progress and randomizing keys to avoid favoring easier ones. Their practice routine involves sight reading, scales, theory drills, ear training, and working on specific pieces. Over the years, they have improved their sight reading speed and confidence, although they still face challenges with key signatures outside their practice range.
The author emphasizes the benefits of randomizing practice to avoid bias towards easier keys and notes that they continue to see improvement even after four years of regular practice. They also mention the limitations of their keyboard, which restricts their fluency in higher and lower piano ranges.

10.The Philosophy of Byung-Chul Han (2020)(The Philosophy of Byung-Chul Han (2020))
Summary of Byung-Chul Han's Philosophy
Byung-Chul Han, a South Korean-born German philosopher, critiques modern society's obsession with achievement and technology. His writings, often concise and accessible, challenge readers to reconsider their beliefs about contemporary culture.
Han argues that we live in an "achievement society," where the pressure to succeed leads to isolation and mental health issues. Unlike the "disciplinary society" of the 20th century, where people followed orders, today's individuals are driven by the idea that they "can" achieve anything. This shift from "should" to "can" fosters a culture of self-exploitation and burnout.
In his book The Burnout Society, Han explains how this relentless pursuit of achievement affects our connections with others and ourselves. He emphasizes that true beauty and authentic experiences come from imperfection and negativity, which are often lost in today’s digital world of smooth, perfect images.
Han also discusses the crisis of love, noting that narcissism and self-obsession hinder genuine connections. In Saving Beauty, he critiques the modern aesthetic, arguing that the lack of ambiguity and negativity in our lives strips away beauty and depth.
His concept of the "transparent society" posits that we willingly expose ourselves in a digital panopticon, where surveillance feels like freedom but ultimately controls us. He suggests that this transparency may even hinder honest political decision-making.
Finally, in Good Entertainment, Han urges a return to play over passion, advocating for creative pursuits that don't focus on productivity. He believes that to connect authentically with the world and others, we need to embrace our imperfections and let go of the constant drive for achievement.
Overall, Han's philosophy encourages introspection and a reevaluation of what it means to be authentic in a society dominated by positivity and perfection.

14.Strengths and limitations of diffusion language models(Strengths and limitations of diffusion language models)
Summary of Diffusion Language Models
Google's new Gemini Diffusion model is notable for its speed in generating text. Here are the key points about diffusion models compared to traditional autoregressive models:
-
Speed of Generation:
- Diffusion models generate the entire output at once, becoming more accurate with each step. In contrast, autoregressive models create text token-by-token.
- This allows diffusion models to generate parts of the output in parallel, making them faster overall, especially for longer outputs. However, for short outputs, autoregressive models might still be quicker.
-
Fixed-Length Outputs:
- Diffusion models typically produce a fixed number of tokens in one go. This can lead to faster generation for longer outputs but may require more passes for shorter outputs compared to autoregressive models.
-
Handling Long Contexts:
- Diffusion models struggle with long contexts because they need to recalculate attention for every token in each pass, unlike autoregressive models, which can cache previous tokens and reduce computation.
-
Reasoning Capabilities:
- It's uncertain how well diffusion models can perform reasoning tasks compared to autoregressive models. While autoregressive models can change their output as they generate tokens, diffusion models might not have the same flexibility due to their block generation style.
-
Use of Transformers:
- Diffusion models can utilize transformer architectures to manage noise, but this doesn't change their fundamental differences from autoregressive models.
In conclusion, while diffusion models offer significant speed advantages for longer outputs, their ability to reason and handle short outputs efficiently remains an area of ongoing research.
15.Everything’s a bug (or an issue)(Everything’s a bug (or an issue))
David Boreham discusses an effective approach to managing software projects centered around bug tracking, based on his experience at a Silicon Valley company. He emphasizes the importance of treating all project tasks as bugs and using a universal bug tracking system, which he describes as having four key principles:
- Comprehensive Bug Tracking: Every task, whether a bug, feature, or documentation issue, should be logged in the system.
- Consistent Schema: Bugs should have a clear and consistent structure to capture their status and priority effectively.
- Single Responsibility: Each bug should be assigned to one person to ensure accountability.
- Flexible Queries: Users should be able to create and share various views of bug lists tailored to their needs.
Boreham reflects on how modern tools like GitHub Issues fall short of these principles, leading to frustrations in project management. While some alternatives offer better functionality, none fully meet the four principles. He suggests that enhancing open-source tools like Gitea could bridge the gap, as they allow for custom feature additions. Boreham concludes with optimism for returning to an ideal software development process that aligns with the principles he values.

21.For algorithms, a little memory outweighs a lot of time(For algorithms, a little memory outweighs a lot of time)
Summary:
Ryan Williams, a theoretical computer scientist at MIT, made a groundbreaking discovery in 2024 about the relationship between time and memory in computing. He proved that a small amount of memory can be just as powerful as a large amount of time for computations, a significant advancement in computational complexity theory that hadn't seen progress in 50 years.
His proof suggests that any algorithm can be transformed to use much less memory while still accomplishing the same tasks. This finding implies that there are problems that cannot be solved within a certain time limit unless more memory is used.
Williams' work challenges long-held assumptions about memory and computation, and his innovative approach is expected to influence future research in the field. Despite initial doubts about his findings, he rigorously verified his proof, which has garnered widespread acclaim in the computer science community.
Overall, Williams' discovery opens new avenues for understanding computational resources and could lead to breakthroughs in one of the oldest unresolved problems in computer science: the relationship between the complexity classes P and PSPACE.
22.A lost decade chasing distributed architectures for data analytics?(A lost decade chasing distributed architectures for data analytics?)
Summary: The Lost Decade of Small Data?
Hannes Mühleisen explores whether we wasted a decade pursuing complex data systems instead of recognizing the power of individual computers for data analytics. He benchmarks DuckDB on a 2012 MacBook Pro to see if it could handle modern data tasks.

-
Data Size vs. Hardware Capability: The growth of useful data sets hasn't kept pace with hardware advancements. Many datasets can now be managed on single machines rather than needing distributed systems.
-
The 2012 MacBook Pro: This model was notable for its SSD and powerful CPU. Mühleisen tests whether this older machine could still run modern data analytics software like DuckDB.
-
Benchmarking: Using a large dataset, the MacBook Pro successfully completed a series of SQL queries, with response times ranging from one minute to half an hour, which are acceptable for analytical tasks.
-
Comparative Performance: When compared to a modern MacBook Pro, the older model showed significant speed differences, but still managed to perform the tasks effectively.
-
Conclusion: The results suggest that a capable SQL engine like DuckDB could have operated well on a single machine back in 2012. This raises questions about the necessity of moving towards distributed systems for data analysis. Mühleisen concludes that we may have indeed lost a decade by not recognizing the potential of existing technology.

25.Direct TLS can speed up your connections(Direct TLS can speed up your connections)
The text discusses how direct TLS (Transport Layer Security) can improve connection speeds to Aurora DSQL (Distributed SQL) databases, particularly when accessing them from AWS offices. Here are the key points:
-
Connection Speed Issue: A team member noticed that when connecting to DSQL clusters without the corporate VPN, connections were slow (around 3 seconds) only in AWS offices.
-
Discovery: This issue was linked to the corporate network, which has both employee and guest WiFi. Testing showed that slow connections occurred on the employee network.
-
TLS Handshake: The problem stemmed from an extra connection made during the TLS handshake process. The corporate firewall was trying to retrieve the server's SSL certificate, which added latency.
-
Firewall Behavior: The firewall was configured to inspect TLS connections, but it struggled with encrypted certificates in TLS 1.3. It opened a second connection for TLS 1.2, which was not how PostgreSQL expected connections to be initiated.
-
Direct TLS Support: PostgreSQL version 17 introduced a direct TLS connection method that skips certain handshake steps, thus avoiding the delay caused by the firewall.
-
Implementation: To use direct TLS, clients need to be on PostgreSQL 17 or higher and set specific parameters. This change eliminated the 3-second delay, resulting in faster connection speeds.
-
Recommendation: It's advised to use direct TLS as it enhances performance without drawbacks, especially in controlled environments. Examples of how to connect using direct TLS are provided for users.
Overall, the introduction of direct TLS in PostgreSQL allows for quicker and more efficient database connections, particularly in corporate environments where network configurations may otherwise slow down connections.
26.CERN gears up to ship antimatter across Europe(CERN gears up to ship antimatter across Europe)
CERN is working on a new portable device to contain antimatter, which is difficult to study due to its short lifespan. They have created a two-meter-long shipping container that can be transported by truck to different labs in Europe. This container uses superconducting magnets and requires a constant power supply and liquid helium to function correctly.
Recently, the team tested the device by loading it with protons and moving it around the CERN campus. The setup managed to keep all the protons contained during the journey, which covered just under 4 kilometers at speeds over 40 km/h.

27.Gemini figured out my nephew’s name(Gemini figured out my nephew’s name)
Summary:
The author created a server that allows a language model (LLM) named Gemini to search their emails for information. They wanted to find the name of Donovan's son.
Gemini suggested a strategy that involved:
- Searching for emails from Donovan.
- Looking for specific keywords like "son," "baby," or "born."
- Examining promising emails and threads for relevant information.
After several searches, Gemini found emails that mentioned other children but not Donovan's son. Eventually, it identified an email where Donovan discussed a child named "Monty," suggesting that Monty is his son.
The author used a custom server with specific tools for searching and retrieving email content, which helped Gemini in the search process. This experience highlighted the LLM’s thought process in finding the name, showing that effective search strategies can lead to success even from initial dead ends.

38.Violating memory safety with Haskell's value restriction(Violating memory safety with Haskell's value restriction)
The text discusses a potential issue with memory safety in Haskell related to its handling of polymorphic references, particularly in the context of the IO monad. Here are the key points:
-
Polymorphic References: In languages with mutable references and polymorphism, such as Haskell, there is a risk of creating unsafe polymorphic references. This can lead to breaking type safety and memory safety.
-
Haskell’s Type System: Haskell does not have a value restriction like some other languages, which prevents generalizing certain types. However, Haskell's type system still prevents unsafe generalization in the case of IO because of how its monadic structures work.
-
Monadic Bindings: In Haskell, the use of monads (like IO) means that types are managed differently compared to regular let bindings. This prevents the creation of polymorphic references when using IO.
-
MonadGen Class: The text introduces a type class called
MonadGen
, which allows for generalization in certain pure monads (e.g., Identity) while ensuring safety. -
Implementation Challenges: While it is possible to generalize in pure monads, doing so with the IO monad is complicated due to its unique structure. Attempting to implement
MonadGen
for IO encounters type errors related to mixing polymorphic and unlifted types. -
Conclusion: Haskell requires a mechanism similar to a value restriction to maintain memory safety, particularly within the IO monad. Unwrapping the IO constructor can lead to unsafe situations, emphasizing the need for careful handling of polymorphic types.
Overall, the text explores the complexities of Haskell's type system and its approach to ensuring memory safety amid powerful features like polymorphism and mutable state.

53.'Turbocharged' Mitochondria Power Birds' Epic Migratory Journeys('Turbocharged' Mitochondria Power Birds' Epic Migratory Journeys)
Birds, like the white-crowned sparrow and Arctic tern, undertake incredible long-distance migrations. To sustain such flights, researchers have found that changes in their mitochondria—tiny energy-producing structures in cells—play a critical role.
Mitochondria are essential for generating energy (ATP) needed for muscle activity. During migration, birds experience significant changes in their mitochondria, becoming more numerous, efficient, and interconnected. This adaptation allows them to fly for thousands of miles without stopping, unlike humans who struggle with long-distance exertion.
Recent studies show that these mitochondrial changes are triggered by seasonal light cycles rather than physical preparation, allowing birds to quickly adapt their energy production. Researchers captured migratory and non-migratory birds to compare their mitochondrial performance. They found that migratory birds had "turbocharged" mitochondria that provided more energy during flight.
This research reveals how birds can enhance their capabilities in response to environmental changes without altering their genetics. However, the increased mitochondrial activity can produce harmful molecules, but birds may counteract this through diets rich in antioxidants.
The findings not only enhance our understanding of bird migration but also suggest potential implications for human health and exercise, as mitochondrial efficiency plays a crucial role in overall energy metabolism.

60.What Is the Difference Between a Block, a Proc, and a Lambda in Ruby? (2013)(What Is the Difference Between a Block, a Proc, and a Lambda in Ruby? (2013))
Summary of Blocks, Procs, and Lambdas in Ruby
In Ruby, blocks, procs, and lambdas are all ways to group and run code, but they have important differences:
-
Blocks:
- Not objects; they are part of method syntax.
- Can be defined using curly braces
{}
or thedo...end
keywords. - Only one block can be passed to a method at a time.
-
Procs:
- Procs are objects, instances of the Proc class.
- Can be assigned to variables and passed around like any other object.
- Do not check the number of arguments passed; if the wrong number is given, they return
nil
for missing arguments and ignore extra ones.
-
Lambdas:
- Lambdas are also objects and a specific type of proc.
- They do check the number of arguments; an error occurs if the wrong number is provided.
- The behavior of the
return
keyword differs:return
exits the surrounding method for lambdas, but for procs, it exits the method where the proc is defined.
Closure: A closure is a function that can remember the environment in which it was created, allowing it to access variables outside its immediate scope.
Key Differences:
- Procs are objects, while blocks are not.
- You can only have one block per method call, but multiple procs can be passed.
- Lambdas enforce argument counts; procs do not.
- The
return
keyword behaves differently in lambdas and procs.
This summary highlights how these three constructs help in organizing code in Ruby, each serving unique purposes with distinct behaviors.

Summary:
Bezel is developing an advanced image generator that learns to enhance its own output. The project focuses on creating detailed personas to help brands tailor advertisements effectively. The system uses the OpenAI Image API for generating and editing images, and employs large language models (LLMs) to evaluate and improve the quality of these images.
Key steps include:
-
Image Generation: Using a prompt to create an ad image (e.g., a Redbull summer campaign), which initially resulted in poor quality due to complexities in the prompt.
-
Evaluation Process: An LLM, referred to as "LLM-as-a-Judge," assesses generated images for issues like text clarity and visual appeal. It identifies specific problems (e.g., blurry text) and suggests improvements.
-
Iterative Refinement: The images are improved in multiple iterations, typically three, focusing on fixing identified issues.
-
Expanding Evaluation: After addressing text clarity, the evaluation was extended to image composition and overall appeal to specific personas. However, combining creative and technical tasks in one model led to poor results.
-
Alternative Approach: A new method using bounding boxes to specify text areas for improvement was tested but found ineffective due to inaccuracies in bounding box generation.
The conclusion highlights that while LLMs excel at reasoning about image issues, they struggle with precise, pixel-level corrections. The findings suggest LLM-as-a-Judge is effective for evaluating image generations, marking a step forward in automated image enhancement.

84.Link Time Optimizations: New Way to Do Compiler Optimizations(Link Time Optimizations: New Way to Do Compiler Optimizations)
Summary of Link Time Optimizations
Link Time Optimizations (LTO) are techniques used to improve the performance and size of compiled programs during the linking phase of development. Traditionally, compilers optimize code within individual files, but they miss opportunities for optimizations across multiple files. LTO allows the linker to perform additional optimizations, such as inlining functions and improving code locality, which can lead to faster and smaller binaries.
Key Points:
-
Compiler Optimizations: Compilers use options like -O0 for debugging and -O3 for performance. They can optimize code within a single file but struggle when functions are spread across multiple files.
-
LTO Advantages:
- The linker can inline functions from different files, reducing function call overhead.
- It can rearrange functions in memory for better data access, which improves performance.
- LTO can yield binaries that are a few percent faster and smaller.
-
Performance Trade-offs:
- Using LTO can significantly increase compilation and linking times and memory usage, especially for large projects.
- For instance, in tests with the ProjectX project, LTO reduced runtime by 9.2% but increased compilation time by about 10 times.
-
Real-world Examples:
- In ProjectX, enabling LTO led to performance improvements.
- However, in ffmpeg, which was already optimized, LTO did not provide the expected benefits, suggesting that LTO is more effective for projects that haven't been heavily optimized.
-
Implementation: To enable LTO, developers need to add the -flto option to both the compiler and linker commands.
Overall, LTO can enhance performance and reduce binary size for many projects, but its effectiveness varies depending on how well-optimized the codebase is already. Developers should measure performance impacts on their specific projects to determine the value of using LTO.

87.Writing into Uninitialized Buffers in Rust(Writing into Uninitialized Buffers in Rust)
Summary: Writing into Uninitialized Buffers in Rust
On March 11, 2025, a new approach for handling uninitialized buffers in Rust was introduced by John Nunley and Alex Saveau. They created a Buffer
trait that is part of rustix 1.0, allowing safer reading into buffers. This trait lets programmers read bytes from a file descriptor into a buffer, which can be either initialized or uninitialized.
Key Features of the Buffer Trait:
- Functionality: The
read
function uses theBuffer
trait to handle various buffer types, including initialized and uninitialized arrays. - Usage:
- For initialized buffers, you can read into a mutable byte array (
&mut [u8]
) and get back the number of bytes read. - For uninitialized buffers (
&mut [MaybeUninit<u8>]
), it returns both the initialized and uninitialized parts of the buffer. - The trait also allows reading into the spare capacity of
Vec
without dynamic allocations.
- For initialized buffers, you can read into a mutable byte array (
Implementation:
The read
function works by calling the system's read operation and then checking how many bytes were read. It uses an unsafe method to ensure the buffer is properly initialized afterward.
Error Handling:
While the Buffer
trait simplifies buffer management, it can sometimes lead to unclear error messages in Rust's compiler, prompting the need for better documentation.
Future Considerations:
The design of the Buffer
trait is proposed as a simpler alternative to Rust's experimental BorrowedBuf
, potentially making its way into Rust's standard library if successful. The goal is to provide a safer and more efficient way to work with uninitialized buffers without requiring full initialization upfront.

96.Environment variables with no equals sign(Environment variables with no equals sign)
The text discusses how environment variables in programming are usually written in the format NAME=value. However, it points out that you can also have environment variables without an equals sign. A C program example shows that you can create an environment variable called "banana" without an equals sign, and when using the env
command, it will still display both "NAME=value" and "banana." The author notes that this doesn't have significant practical use, as shells like bash will simply ignore variables without an equals sign.

98.Did Akira Nishitani Lie in the 1994 Capcom vs. Data East Lawsuit?(Did Akira Nishitani Lie in the 1994 Capcom vs. Data East Lawsuit?)
The article discusses the 1994 lawsuit between Capcom and Data East, where Capcom accused Data East's game "Fighter's History" of copying "Street Fighter II." A key point of contention is a deposition from Akira Nishitani, co-designer of Street Fighter II, who claimed that their game's characters were not inspired by other sources, including video games and comics. This statement is considered dubious, as research indicates that many characters in Street Fighter II were influenced by real-life martial artists, movies, and other games.
The lawsuit arose after Street Fighter II's success in 1991 led to many imitators, with Fighter's History being one of the most similar. Capcom filed a suit alleging copyright violations and sought damages. However, the judge ruled that while Fighter's History was derivative, it did not violate copyright laws, allowing the game to continue in arcades.
The article also explores why Nishitani might have made his claim. It suggests that he may not have been lying but rather emphasizing a different creative philosophy, arguing that Data East's game was a more blatant copy than Capcom’s original creation. The legal documents reveal various disputes over what constitutes inspiration versus copying, as well as comparisons to other fighting games like "Mortal Kombat II."
Ultimately, the ruling favored Data East, and the article concludes that while Nishitani's statement contradicts evidence of inspiration from other sources, there may be a nuanced perspective where he believed Capcom's approach was more original than Data East's.
99."Microsoft has simply given us no other option," Signal blocks Windows Recall("Microsoft has simply given us no other option," Signal blocks Windows Recall)
Signal, a messaging app, is warning its users about privacy risks from a new AI tool called Recall in Windows 11. Recall can take screenshots and store user activity every few seconds, potentially exposing private messages, including those from Signal.
To protect user privacy, Signal has made its app on Windows block screenshots by default. Users who want to allow screenshots need to change their settings. Despite Microsoft updating Recall to be opt-in and encrypt data, concerns remain about what it can index, including sensitive information.
Signal is using a copyright protection feature from Microsoft to prevent Recall from taking screenshots of messages, highlighting the lack of proper privacy controls for developers. This workaround helps protect user privacy but has limitations, as it only works if all chat participants use the default settings. Microsoft has not commented on the lack of control for developers over Recall.
