2.The Princeton INTERCAL Compiler's source code(The Princeton INTERCAL Compiler's source code)
A new book titled "Forty-Four Esolangs" will be released on September 23, 2025, focusing on programming language concepts. It features the original source code of the INTERCAL-72 compiler for the first time.
INTERCAL, created in 1972 by Don Woods and Jim Lyon, is known as the first esolang (esoteric programming language) and is designed to humorously frustrate programmers. It uses unconventional symbols and structures, making it difficult to read or run. The language is meant for parody rather than practical use.
INTERCAL has influenced many minimalist languages that followed but stands out for its unique approach to programming as a dramatic experience. Notably, it personifies the interpreter, which reacts to the programmer's use of the command "PLEASE"—too little or too much will lead to the program being ignored. This feature has inspired later parody languages and even interpretations in other programming contexts.
Most people today use derivatives of INTERCAL, such as C-INTERCAL, which introduced new elements like the "COME FROM" statement. The original INTERCAL-72 code can now be accessed, allowing for fresh exploration of this pioneering language.
Sean Haas has worked on running the INTERCAL compiler on modern systems and explained some of its quirks, like performing math through string manipulation, which contributes to its notable inefficiency. The scans and transcriptions of the original code are available on GitHub.

7.How to post when no one is reading(How to post when no one is reading)
The journey to becoming a successful creator often starts with years of unnoticed work. Many creators publish content for a long time with little to no audience—think YouTube videos with only a few views or songs that hardly get played. It can take years, or even a lifetime, of effort before receiving recognition, as seen in the case of Van Gogh, who gained fame only after his death.
To keep going during these tough times, consider these strategies:
-
Create What You Love: Focus on making things you enjoy. Mike Posner, for example, initially chased hits but found happiness and success by producing music he liked, leading to a healthier mindset and new hits.
-
Stay True to Yourself: Don't worry about what others want; create what resonates with you. This approach can help maintain motivation and attract like-minded fans.
-
Invest in Your Future Audience: Treat your early work as an investment in your "Binge Bank." This is a collection of content that future fans will appreciate. Just because no one is watching now doesn’t mean they won’t in the future.
If you feel like you're publishing into obscurity, remember to keep creating. Your efforts will pay off in time.
8.TPDE: A Fast Adaptable Compiler Back-End Framework(TPDE: A Fast Adaptable Compiler Back-End Framework)
Fast machine code generation is crucial for quick start-up times in just-in-time (JIT) compilation, as longer compilation times can increase overall latency. However, popular compiler frameworks like LLVM do not focus on fast compilation and include an additional intermediate representation (IR) translation step that adds to this delay. Creating a custom code generator for different architectures is also a challenging task.
In response, this paper introduces TPDE, a compiler back-end framework that works with existing code formats in Static Single Assignment (SSA) form. TPDE uses a specialized adapter to access IR data structures and defines the semantics of the IR. It allows for a streamlined compilation process in just one pass, which includes selecting instructions, allocating registers, and encoding instructions. The output is primarily high-level code, making it easier to adapt to various architectures while still allowing for optimizations.
To demonstrate its versatility, the authors built a new LLVM back-end targeting x86-64 and AArch64. Performance tests show that TPDE can compile LLVM-IR 8 to 24 times faster than LLVM with no optimization, while still achieving similar run-time performance. The framework also shows advantages in JIT scenarios, such as with WebAssembly and database queries, by eliminating the extra IR translation step and reducing compilation time.
9.How Can AI Researchers Save Energy? By Going Backward(How Can AI Researchers Save Energy? By Going Backward)
AI researchers are exploring reversible computing as a way to save energy. This approach allows computations to run backward as well as forward, which could reduce energy waste associated with data deletion.
The idea dates back to the 1960s when physicist Rolf Landauer discovered that deleting information in computers leads to energy loss as heat. Charles Bennett later proposed "uncomputation," where calculations are run forward and then backward to retain energy, but this was initially impractical due to time constraints.
Interest in reversible computing waned until recent advancements highlighted its potential, especially for AI, which requires significant computing power. Running reversible chips slowly while using multiple processors could save energy and reduce cooling needs. Researchers like Hannah Earley have demonstrated the efficiency of reversible computers, leading to commercial ventures aimed at developing these chips.
Overall, reversible computing offers a promising solution to the energy challenges facing modern AI and computing.

14.What works (and doesn't) selling formal methods(What works (and doesn't) selling formal methods)
Summary of the Text:
This document discusses the challenges and insights related to selling and implementing formal methods (FM) in projects, particularly from the perspective of Mike Dodds at Galois.
-
Understanding Costs and Benefits: Successful formal methods projects need to balance costs (time, money, resources) with benefits (security, reliability). If a project doesn’t make sense in terms of these factors, it won’t be pursued by clients.
-
Deliver Value Early: Formal methods projects often require significant upfront investment before clients see benefits. Projects should be structured to provide early, tangible results to keep clients engaged.
-
Perception of Correctness: Many clients do not prioritize achieving the highest level of correctness in their software. They may already accept some bugs and prefer to focus on other pressing needs, making it crucial to align project goals with their priorities.
-
Defining Success: Clear communication about project outcomes is essential. Clients often misunderstand the implications of formal methods, leading to misaligned expectations. It’s important to clearly outline what success looks like to avoid confusion later on.
-
Start with Affordable Solutions: Before diving into expensive formal methods, it’s recommended to first leverage cheaper techniques (like testing and code reviews) that can effectively improve software reliability.
-
Integration of Techniques: Combining formal methods with traditional assurance techniques can provide a more comprehensive approach, rather than positioning them as mutually exclusive options.
Overall, the key takeaway is that for formal methods to be adopted more widely, they must demonstrate clear value, align with client priorities, and be presented in a way that clients can understand and appreciate.
15.Writing your own C++ standard library part 2(Writing your own C++ standard library part 2)
Summary of "Writing Your Own C++ Standard Library Part 2"
In this blog post by Jussi Pakkanen, he discusses his personal project of creating a custom C++ standard library. He clarifies that his library is not a complete implementation of the ISO standard but rather a collection of essential functions and types for applications.
Two main points of discussion arose from readers:
- Some criticized him for not providing a full ISO standard library, which he acknowledges but insists was not his goal.
- There was debate over the terminology, particularly the use of "STL" to refer to the C++ standard library, which led to arguments among commenters.
He also addresses the complexities of existing container implementations, noting that they need to handle various types of data and their behaviors. His approach to simplify this is to require all types used in his containers to be "WellBehaved," which avoids dealing with problematic types.
Pakkanen highlights the differences between handling strings in Python and C++. He created two versions of a string-splitting function, one similar to Python's behavior and another that is more flexible but requires additional user input.
Currently, his library supports basic string functionality and regex, and can compile quickly, taking about 0.1 seconds per file. Overall, he is experimenting with C++ to create a more user-friendly library.

17.A new generation of Tailscale access controls(A new generation of Tailscale access controls)
Tailscale has introduced a new access control feature called "grants," which simplifies how permissions are written and understood compared to the older ACL syntax. Grants allow users to manage network and application permissions in a more straightforward way, combining elements that were previously separate.
Key points about grants:
- They are easier to write and read than ACLs, with a simplified syntax that combines ports and protocols into one field.
- Grants can express everything that ACLs can, making them a more versatile option.
- They facilitate better authentication and authorization for applications by allowing developers to define user capabilities directly within the grants.
- Grants include a new "via" field for routing traffic through specific exit nodes or routers based on user groups.
Existing Tailscale users don't need to worry about immediately converting their old ACL rules; both ACLs and grants can be used together indefinitely. Users can gradually transition to grants to utilize new features as needed.

20.Progressive JSON(Progressive JSON)
Summary of Progressive JSON
Progressive JPEGs load images in a way that starts fuzzy and becomes clearer over time. The idea can be applied to JSON data transfer, allowing clients to start working with data as it arrives instead of waiting for the entire JSON object to load.
-
Current JSON Transfer Method: Traditional JSON loading requires the entire object to be sent before it can be processed. This means if any part of the JSON takes time to generate, the client must wait, which is inefficient.
-
Streaming JSON: A streaming JSON parser could allow parts of the object tree to be processed as they are received. However, this often results in incomplete or malformed data, making it difficult for clients to use.
-
Progressive JSON Approach: Instead of sending data depth-first (from top to bottom), a breadth-first approach can be used:
- Placeholders (like "$1") represent data that will be filled in later.
- Clients can start processing the data even if some parts are still loading, using Promises to indicate incomplete information.
-
Inlining and Outlining Data:
- Inlining sends data compactly unless it’s slow to generate, while outlining reduces repetition by referencing previously sent objects.
- This system can also handle cyclic objects more easily than standard JSON.
-
React Server Components: The approach resembles how React handles server components. Data streams in progressively, allowing the client to build the UI incrementally without visual interruptions. Using the
<Suspense>
component, developers can control when to display loading states, ensuring a smooth user experience. -
Conclusion: The post encourages adopting progressive streaming in more applications to improve data transfer efficiency, particularly in scenarios where slow data generation can delay client processing. React’s model of handling incomplete data with intentional loading states is highlighted as a solution to utilize streaming effectively.

27.Making maps with noise functions (2022)(Making maps with noise functions (2022))
This text discusses techniques for generating 2D maps using noise functions, specifically focusing on a simple method that allows for creating diverse landscapes in under 50 lines of code. Here are the key points simplified:
-
Map Generation Basics:
- The process starts with filling an array with height and biome data using noise functions like Simplex or Perlin noise.
- Each location on the map is assigned a value between 0.0 and 1.0, which can represent different features like elevation.
-
Elevation and Frequency:
- Elevation is derived from noise values. By adjusting the frequency of the noise, different terrain features can be created (e.g., hills vs. flat areas).
- Using multiple frequencies, known as octaves, creates more complex terrains that include both large and small features.
-
Biomes and Climate:
- Biomes (like forests, deserts, etc.) are assigned based on elevation and moisture levels, which can also be generated with noise functions.
- Climate can be influenced by both elevation and latitude, affecting temperature across the map.
-
Islands and Terraces:
- Techniques to create island maps involve adjusting elevations at the map's edges to ensure they are surrounded by water.
- Terraced landscapes can be created by rounding elevation values to specific levels.
-
Tree Placement:
- Objects like trees can be placed using noise functions to create irregular patterns, though alternatives like Poisson disc sampling may yield better distributions.
-
Wraparound Maps:
- Maps can be designed to wrap around, meaning the east edge connects to the west edge, simulating a cylindrical world.
-
Infinite Terrain:
- The method allows for generating infinite terrain by calculating map data based on the camera's position, making it possible to create expansive worlds without storing all data at once.
-
Implementation:
- The code for generating noise and creating maps is similar across various programming languages, and many libraries are available to facilitate this process.
-
Limitations:
- While the approach is simple and effective for quick map generation, it can lead to repetitive patterns and lacks global features like rivers or lakes.
-
Further Exploration:
- The text encourages experimentation with different noise functions and parameters to achieve unique results and suggests various resources for deeper learning about noise and terrain generation.
Overall, this method serves as a foundational approach for game developers looking to create procedurally generated maps with relative ease.

32.Why DeepSeek is cheap at scale but expensive to run locally(Why DeepSeek is cheap at scale but expensive to run locally)
The text explains why DeepSeek-V3 is efficient at scale but expensive and slow for local use. Here are the key points simplified:
-
Throughput vs. Latency: AI models face a trade-off between throughput (how many requests they can handle at once) and latency (how quickly they respond). High throughput often leads to higher latency because requests are batched together.
-
Batch Inference: GPUs excel at processing large batches of data. For example, processing ten tokens at once is much faster than processing them one by one. This is because one large operation (matrix multiplication) is more efficient than several smaller ones.
-
Collection Windows: Inference servers collect user requests over a set time (the "collection window") before processing them in batches. A longer window can improve efficiency by allowing more requests to be processed together, but it increases latency as users might have to wait longer.
-
Mixture of Experts: Models like DeepSeek-V3 use a technique called mixture of experts, which divides the workload among different specialized units. This requires larger batch sizes to keep all units busy, leading to longer wait times for users.
-
Pipeline Efficiency: Large models with many layers need to avoid idle GPU time (known as "pipeline bubbles") by ensuring enough tokens are processed at once. Longer collection windows help achieve this, but also increase user wait times.
-
Local vs. Scaled Use: Running models locally means processing requests one at a time, which results in low efficiency and throughput. In contrast, large-scale providers can batch many requests, making the system more efficient.
-
Fast Providers: Companies like OpenAI and Anthropic may use more efficient model architectures or have better resource allocation to achieve faster response times compared to models like DeepSeek-V3, which require high latency for efficiency.
In summary, DeepSeek-V3 is designed for efficient processing at scale but struggles with low throughput and high latency when used locally.

76.Atlas: Learning to Optimally Memorize the Context at Test Time(Atlas: Learning to Optimally Memorize the Context at Test Time)
Transformers are widely used in sequence modeling because they are effective for tasks that require retrieving information from context. However, they have limitations in handling long sequences due to their high memory and time requirements. This has led researchers to look for better alternatives, such as modern recurrent neural networks, but these also struggle with understanding long contexts.
The main issues with current models are:
- Limited memory capacity due to their design.
- They only update memory based on the most recent input.
- They do not manage their fixed-size memory very well.
To address these problems, a new long-term memory module called ATLAS has been developed. ATLAS improves memory capacity and learns from both current and past information, avoiding the limitations of previous models. Additionally, a new family of architectures called DeepTransformers has been created, which extends the original Transformer model.
Tests show that ATLAS performs better than traditional Transformers and recent linear models in various tasks, including language modeling and long-context understanding. It significantly improves performance on long-context tasks, achieving over 80% accuracy on a specific benchmark.
77.An optimizing compiler doesn't help much with long instruction dependencies(An optimizing compiler doesn't help much with long instruction dependencies)
The article discusses the effectiveness of optimizing compilers in improving software performance, particularly for memory-intensive tasks. The author investigates whether compiling code in debug mode versus release mode affects performance, especially for large AI models.
Key points include:
-
Memory-Bound Code: The author tests a memory-intensive code snippet that accesses data randomly from a vector. They compare the performance of the code compiled with no optimizations (-O0) and full optimizations (-O3).
-
Performance Findings: On ideal hardware, the O0 version generates significantly more instructions than O3, suggesting it should run slower. However, real hardware shows that while O3 is faster, the improvement is less than expected as the dataset size increases.
-
Instruction Level Parallelism (ILP): The first code snippet has a good amount of ILP, allowing the CPU to execute loads in parallel, leading to faster performance. In contrast, a second example using a linked list has low ILP, causing delays as the CPU waits for data, making optimizations less effective.
-
Conclusion: While an optimizing compiler can improve performance, its benefits are limited in cases with low ILP, meaning that sometimes the hardware and memory constraints are the real bottlenecks, not the code itself.
The author encourages readers to reach out for help with performance issues in their projects.
78.Why Use Structured Errors in Rust Applications?(Why Use Structured Errors in Rust Applications?)
Summary: Why Use Structured Errors in Rust Applications

-
Custom Error Types: Creating specific error types helps provide clear information about what went wrong, making it easier for developers to understand and maintain the code.
-
Libraries vs. Applications: Libraries should use detailed error types to help callers handle errors effectively, while applications often use simpler error handling methods like
anyhow
, which makes dealing with errors more convenient. -
Advantages of Structured Errors:
- Custom error types show all possible failure modes clearly.
- They help maintain consistency in error messaging.
- They can be enriched with extra data and functionality (e.g., logging, HTTP status codes).
- Code reviews become easier since the error types are well-defined.
-
Trade-offs:
- Custom errors require more code and initial setup, which can increase maintenance.
- Developers must think carefully about error naming and structuring.
- Additional dependencies, like
thiserror
, may be needed to reduce boilerplate code.
-
Conclusion: Despite the challenges, the benefits of using structured errors—such as better clarity and maintainability—often outweigh the drawbacks, making them valuable in application development. The author plans to explore managing custom error types and provide examples in future posts.
79.The Two Ideals of Fields(The Two Ideals of Fields)
Summary of "Two Ideals of Fields" by Susam Pal
A field is defined as having exactly two ideals: the zero ideal (which contains only the number zero) and the field itself. These are called trivial ideals. If a commutative ring has no ideals other than these two, it is classified as a field.
Key Points:
-
Definition of Ideals:
- An ideal is a subset of a ring that is an additive subgroup and absorbs multiplication by any ring element.
- In commutative rings, left and right ideals are the same, simply called ideals.
-
Examples:
- The set of even integers is an ideal in the integers.
- In the ring of polynomials with integer coefficients, the set generated by 2 and a variable (t) forms an ideal.
-
Ideals in Fields:
- A field has only two ideals: {0} and the field itself.
- If an ideal contains a non-zero element, it must contain all elements of the field, thus proving that the only ideals are trivial.
-
Rings with Trivial Ideals:
- If a commutative ring has only the trivial ideals, then every non-zero element has a multiplicative inverse, making it a field.
-
Conclusion:
- Every field is a commutative ring with distinct identities and only trivial ideals, and vice versa. This symmetry in their definitions is noteworthy.
This summary highlights the essential concepts regarding fields and their ideals, making the topic easier to understand.

90.Ru and W isotope systematics in ocean island basalts reveals core leakage(Ru and W isotope systematics in ocean island basalts reveals core leakage)
The article discusses the findings related to the isotopic composition of ocean island basalts (OIB), particularly focusing on the elements ruthenium (Ru) and tungsten (W). Researchers found that the Ru isotope variations in Hawaiian basalts are higher than those in the regular mantle, suggesting that these basalts may contain material from Earth's core. This supports the idea that core material can influence the composition of mantle sources.
The study indicates that the differences in Ru isotopes could provide a new method to understand the interactions between the Earth's core and mantle. The researchers reported specific Ru isotope data from various basalt samples, showing that Hawaiian basalts are enriched in certain Ru isotopes compared to the upper mantle. This enrichment is linked to core material and suggests a potential contribution from the core to the mantle through processes occurring at the core-mantle boundary. Overall, these findings highlight the importance of Ru isotopes in tracing core-mantle interactions.
91.The Illusion of Causality in Charts(The Illusion of Causality in Charts)
The text discusses how charts can give a misleading impression of causality, meaning they can suggest that one event causes another when that may not be true. This "implied causality" can be found in various chart types, including line charts, bar charts, scatter plots, and maps.
Key points include:
-
Line and Bar Charts: These can suggest a causal relationship by showing trends before and after an event or by comparing different groups. For example, a comparison of heart disease rates in vegans versus omnivores might imply that diet alone causes differences, ignoring other health factors.
-
Scatter Plots: These often show correlations between two variables, which can lead to the assumption that one causes the other. However, other factors may influence the results, and it's essential to consider how the data was collected.
-
Maps: Maps can imply causality by comparing regions with different policies or by showing spatial proximity to a potential cause, like pollution. However, proximity alone does not confirm a causal link.
-
General Patterns of Implied Causality: Four main mechanisms can indicate implied causality across various charts:
- Factor: Comparing groups that differ by one factor.
- Event: Comparing states before and after an event.
- Covariation: Observing how two quantities change together.
- Proximity: Considering the closeness to a source that might affect outcomes.
Understanding these principles helps in critically evaluating data visualizations and avoiding incorrect conclusions about causal relationships.
92.Java Virtual Threads Ate My Memory: A Web Crawler's Tale of Speed vs. Memory(Java Virtual Threads Ate My Memory: A Web Crawler's Tale of Speed vs. Memory)
Summary:
Dario Balinzo experimented with a web crawler using Java's Virtual Threads instead of traditional platform threads. While Virtual Threads greatly increased the speed of processing URLs, it led to an OutOfMemoryError because the system couldn't handle the rapid influx of data without any limits.
Initially, Balinzo created a basic web crawler using platform threads, processing a predetermined list of URLs. When he switched to Virtual Threads, the URL fetching became significantly faster, but the processing couldn't keep up, causing excessive memory usage.
To solve this issue, he suggested two approaches:
- Limit concurrency: Use a semaphore to control the number of tasks running simultaneously, preventing overwhelming the system.
- Rate limiting: Avoid submitting too many tasks at once, spreading requests over time to mimic realistic scenarios.
This experience highlighted that while Virtual Threads offer performance benefits, they require careful management of resources and concurrency to avoid memory problems.
93.Designing Pareto-optimal RAG workflows with syftr(Designing Pareto-optimal RAG workflows with syftr)
Summary of "Designing Pareto-optimal GenAI workflows with syftr"
