APL Interpreter – An implementation of APL, written in Haskell (2024)
(APL Interpreter – An implementation of APL, written in Haskell (2024))

The document discusses the development of an APL interpreter in Haskell. Here are the key points:

  1. What is APL?: APL is an array programming language that uses multidimensional arrays as its sole data type. Its unique syntax, which utilizes single Unicode symbols for operations, allows for compact and expressive code.

  2. Learning APL: The author finds APL's approach requires a different mindset, akin to functional programming, focusing on high-level operations rather than low-level recursion.

  3. Why Haskell?: The project was initially aimed at exploring APL, with Haskell as a side project. However, working with Haskell turned out to be more challenging, particularly in managing state and performance.

  4. Interpreter Structure: The interpreter reads text input, converts it to tokens, parses those tokens into a syntax tree, evaluates the tree, and prints the results. The state of the interpreter is tracked throughout this process.

  5. Parsing: The author chose to build the parser from scratch to understand its workings better, using helper functions to translate between imperative and functional styles.

  6. Match Functions: The core logic involves "MatchFn," which processes lists of tokens. This evolved through several versions, eventually integrating monads to manage state more elegantly.

  7. Evaluation: The evaluation of functions in APL can be complex, especially with higher-dimensional arrays. The author emphasizes the importance of indexing and shape manipulation in handling these arrays.

  8. Dyalog APL: The project is heavily inspired by Dyalog APL, aiming to replicate its syntax and behavior. However, discrepancies exist, particularly in how certain functions are implemented and how errors are handled.

  9. Challenges with Haskell: The author appreciates Haskell's compiler for its error-checking but finds the learning curve steep. Debugging is complicated by Haskell's lazy evaluation model, which can lead to delayed error reporting.

  10. Final Thoughts: The author reflects on the experiences gained from the project, highlighting both the benefits and difficulties of using Haskell for this complex task. The project showcases both the potential of array programming and the intricacies of functional programming languages.

Machine Learning: The Native Language of Biology
(Machine Learning: The Native Language of Biology)

Evan Peikon's article, "Machine Learning: The Native Language of Biology," discusses how machine learning is better suited for understanding biological systems compared to traditional mathematical methods.

Key points include:

  1. Limitations of Traditional Mathematics: Mathematical models often fail to capture the complexity of biological systems, which are influenced by interconnectedness, diversity, and high dimensionality. While some mathematical models work for specific biological phenomena (like predator-prey dynamics), many important biological challenges do not fit neatly into mathematical frameworks.

  2. Machine Learning's Advantages: Machine learning allows complex relationships to emerge from data without requiring simplified, human-readable equations. It excels at handling high-dimensional data and capturing context-dependent interactions, which traditional math struggles to do.

  3. Biology as a Language: Similar to natural language, which has context-dependent meanings, biological processes can change based on their environment. Machine learning can model these complexities effectively, as seen in the behavior of transcription factors that change roles depending on context.

  4. Predictive Biology: This emerging field focuses on predicting biological outcomes rather than just cataloging functions or interactions. It emphasizes building models that can foresee how biological systems will respond to different conditions.

  5. Future of Bioengineering: Embracing machine learning in bioengineering could lead to revolutionary advancements, such as designing responsive cellular therapies and creating organisms with novel properties. While traditional methods will still have value, machine learning is becoming the preferred approach for tackling complex biological problems.

Overall, Peikon suggests that just as mathematics has unlocked the laws of physics, machine learning may be key to deciphering the complexities of life.

What a developer needs to know about SCIM
(What a developer needs to know about SCIM)

Summary of SCIM for Developers

Purpose of SCIM
SCIM (System for Cross-domain Identity Management) helps large companies manage user access to various software applications. It centralizes user permissions and allows IT teams to efficiently manage who can access what applications without compromising security.

Role of Identity Providers (IDPs)
IDPs, like Okta and OneLogin, act as databases that store user information and manage access to applications. They communicate changes about user accounts (adding, updating, or removing users) to other software using SCIM.

How SCIM Works
SCIM uses standardized JSON messages for:

  • Creating new user accounts.
  • Updating user information.
  • Deleting user accounts.

For example, when a user is added or their role changes, the IDP sends a JSON message to your software to update the user records accordingly.

Common Misconceptions About SCIM

  • SCIM is not directly related to compliance or data retention.
  • It does not dictate how to manage user sessions or require real-time updates.
  • Implementing SCIM does not necessarily mean you need to overhaul your software’s user management system.

Technical Details
SCIM functions through CRUD (Create, Read, Update, Delete) operations, using HTTP methods (GET, POST, PUT, PATCH, DELETE). Your software acts as a server that responds to requests from the IDP, which is the client.

Challenges with SCIM

  • Implementing SCIM can involve complex operations, especially with PATCH requests that modify existing data.
  • Some IDPs may not fully comply with the SCIM specification, leading to inconsistencies and requiring additional adjustments in your implementation.

Recommendation
Building a SCIM solution from scratch is generally not advisable. It can be time-consuming and may detract from focusing on more critical customer needs. Instead, consider using existing off-the-shelf SCIM solutions to streamline the process.

Humans organize knowledge by grouping similar ideas into simple categories while keeping their meanings. For example, both robins and blue jays are categorized as birds, which share common traits like the ability to fly. This process balances detail and simplicity. Large Language Models (LLMs) are good at language tasks, but it’s uncertain if they categorize information like humans do.

To explore this, researchers created a new framework based on information theory to compare how LLMs and humans categorize information. They analyzed data from various LLMs and compared it to human categorization standards. They found that while LLMs create broad categories similar to humans, they often miss subtle distinctions that are important for human understanding. LLMs tend to compress information too aggressively, while humans focus on context and nuance, even if that makes their categorization less efficient. These differences highlight gaps between AI and human thinking and suggest ways to improve LLMs for better alignment with human concepts.

Reproducing the deep double descent paper
(Reproducing the deep double descent paper)

Summary: Reproducing Deep Double Descent

In summer 2025, a beginner in machine learning (ML) has been learning intensively at the Recurse Center. After gaining some basic knowledge, they aimed to reproduce results from a paper on "Deep Double Descent," which explains how larger models can sometimes perform better after initially degrading in accuracy.

Key Concepts:

  • Double Descent: This phenomenon shows that as model size increases, accuracy can first drop before improving again. Smaller models may not capture the problem well, while larger models can overfit but eventually learn better features.
  • Training and Testing: Models are evaluated on separate datasets. A model that performs well on training data but poorly on test data is said to generalize poorly.

Project Goals: The author focused on reproducing results related to varying sizes of ResNet18 models, simplifying their initial approach to save time. They trained models on the CIFAR-10 dataset instead of the larger ImageNet, requiring adjustments to the model architecture.

Challenges Faced:

  • Model Configuration: The author encountered issues with the standard ResNet18 implementation, which was meant for larger images. They had to modify the model to fit their needs.
  • Training Time: The training process was initially estimated to take nearly five months, but the author reduced it to about 10 days by renting GPU time.

Results:

  • The experiments showed notable double descent effects at higher label noise levels.
  • With no noise, models performed well without double descent. With 10% and 20% noise, both model-wise and epoch-wise double descent were observed, confirming findings from the original paper.

Conclusion: The author successfully reproduced the results from the paper, learning a great deal about the process along the way. They expressed satisfaction with the journey from initial learning to achieving working models in ML.

Summary of iPhone 15 Pro's Depth Maps and Image Processing

Since 2017, Apple iPhones have included depth maps in images using technologies like LiDAR and structured-light scanning. These images are stored in High Efficiency Image File Format (HEIF), which can hold multiple images and metadata. While HEIC is the default format, JPEG can be used if depth maps aren't needed.

Finn Jaeger, a VFX head at Replayboys, is working on a project called HEIC Shenanigans, which helps extract images and metadata from HEIC files and convert them into EXR files. His project involves using Python, and he has shared a codebase for this.

The author uses a powerful computer setup with Ubuntu and various tools to process an HEIC image sent by an expert. They extract the gain map and depth map from the image, producing files with specific metadata details.

Additionally, the author discusses converting HEIC images into OpenEXR format, which is widely used in visual effects. This process involves several steps using an image processing tool called oiiotool.

Ultimately, the final output is a comprehensive EXR file that includes the base image, gain map, and depth map, ready for further visual effects work. The author offers consulting services for those interested in their expertise.

Cysteine depletion triggers adipose tissue thermogenesis and weight loss
(Cysteine depletion triggers adipose tissue thermogenesis and weight loss)

The article discusses research on the effects of cysteine depletion on weight loss and fat metabolism. Key findings include:

  1. Cysteine and Weight Loss: Reducing caloric intake leads to lower levels of cysteine in human fat tissue. Experiments in mice showed that a lack of cysteine caused significant weight loss by increasing fat utilization and changing white fat cells to a brown fat-like state, which burns more energy.

  2. Mechanism: The process of fat browning and weight loss from cysteine depletion depends on the sympathetic nervous system, specifically through noradrenaline signaling. This response occurs independently of two other factors often linked to fat metabolism, FGF21 and UCP1.

  3. Dietary Implications: In obese mice, removing cysteine from their diet resulted in rapid fat browning and a 30% weight loss, also improving inflammation linked to obesity.

  4. Cysteine's Importance: The study highlights that cysteine is crucial for metabolism; its absence triggers quick fat changes and weight loss. Restoring cysteine in the diet can reverse these effects.

  5. Broader Context: The findings suggest that understanding cysteine's role could lead to new ways to combat metabolic disorders and improve health, especially in the context of caloric restriction strategies.

Overall, the research establishes cysteine as a vital amino acid for maintaining healthy metabolism and body weight.

Neuromorphic computing
(Neuromorphic computing)

Neuromorphic computing is an advanced form of artificial intelligence (AI) that aims to be smaller, faster, and more efficient than the human brain. Current AI systems, particularly large language models, consume an enormous amount of energy—projected to exceed the U.S. GDP by 2027. Researchers at Los Alamos and the Department of Energy are working to create AI that operates on just 20 watts, similar to the energy used by the human brain.

This new approach mimics the brain's structure and function using energy-efficient networks, rather than traditional supercomputers. These neuromorphic systems are designed to learn and adapt like humans, allowing for better context recognition and decision-making. For example, they could differentiate between a STOP sign and a STOP sign on a t-shirt, unlike current AI which reacts to signals without context.

Experts are exploring which animal brains to study for insights, and they are developing new low-energy processors to support this technology. Currently, large neuromorphic computers have over a billion neurons and aim to replicate the complexity of the human brain.

The goal is to design a neuromorphic computer that fits in a small space and operates significantly faster than a biological brain while using minimal power. This could lead to a future where AI is as energy-efficient and intelligent as human brains.

Summary: How We Reduced the Impact of Zombie Clients

Samantha Frank's blog post discusses the issue of "zombie clients"—abandoned or misconfigured servers that repeatedly request digital certificates from Let’s Encrypt, even though they are no longer valid. These requests waste resources because the software does not stop trying to renew certificates, leading to significant inefficiencies.

Key Points:

  1. The Problem: Many devices keep requesting certificates for domain names they no longer own, leading to high rates of failed requests and resource consumption.

  2. Rate Limiting: Let’s Encrypt introduced a rate limit system to manage these zombie clients. The limits are designed to be non-punitive, aiming to conserve resources without frustrating genuine users.

  3. Zombie-Specific Measures: A new approach called "pausing" was implemented, where accounts that continuously fail to validate for a specific hostname are temporarily limited in their ability to make further requests. This helps conserve resources without affecting other valid requests from the same account.

  4. Self-Service Unpausing: Users can easily reactivate their accounts if they notice issues. A feature allows them to unpause their account-hostname pair after resolving the underlying problem.

  5. Results: Since implementing these measures, Let’s Encrypt has paused over 100,000 problematic accounts, reduced failed certificate orders by about 30%, and received minimal complaints from users.

  6. Future Considerations: Let’s Encrypt plans to discontinue renewal reminder emails, which may lead to more zombie clients. The self-service unpause feature will help manage this potential increase.

Overall, the measures taken have successfully reduced the load on Let’s Encrypt’s infrastructure while ensuring minimal disruption for active users.

The text discusses the challenges of achieving Artificial General Intelligence (AGI) and critiques the current reliance on generative AI models, particularly large language models (LLMs). Here are the key points simplified:

  1. Misunderstanding of AGI: Many believe AGI is close due to the success of generative AI, but these models do not genuinely replicate human intelligence. They perform well because they have been scaled effectively rather than because they truly understand intelligence.

  2. Need for Physical Understanding: True AGI must have a grasp of the physical world, as many real-world tasks cannot be reduced to mere symbol manipulation. Current models like LLMs only predict text based on patterns, lacking a deep understanding of the world.

  3. Limitations of Current Models: While LLMs seem competent in language, they often rely on memorizing rules rather than forming a true understanding of semantics (meaning) and pragmatics (contextual use). This indicates a superficial grasp of language rather than real intelligence.

  4. Critique of Multimodal Approaches: The idea of combining different types of AI models (like visual and textual) into a single AGI is viewed as flawed. This approach risks oversimplifying how different forms of intelligence work together and may not lead to truly general intelligence.

  5. Need for Structural Thinking: Building AGI will require thoughtful consideration of how different modalities (language, vision, actions) interact. A purely scale-driven approach is unlikely to yield a complete and functional AGI.

  6. Conclusion: The path to AGI should focus on creating systems that learn and interact with the world in a grounded way, rather than just integrating existing models. This will involve a deeper understanding of how intelligence operates across various modalities.

Overall, the text argues for a more integrated and embodied approach to developing AGI, emphasizing the importance of understanding the physical world and the interactions between different forms of intelligence.

DiffX – Next-Generation Extensible Diff Format
(DiffX – Next-Generation Extensible Diff Format)

Summary of DiffX - Next-Generation Extensible Diff Format

Diff files are commonly used by software developers to show differences between text files, indicating inserted (+) and deleted (-) lines. Most developers are familiar with Unified Diffs, which have limitations, such as a lack of standardization in encoding, metadata, and file paths. This inconsistency makes it difficult for tools to reliably parse and analyze diffs.

Unified Diffs are widely used but haven’t evolved to meet modern needs, lacking the ability to represent multiple commits, binary patches, and standard metadata formats. To address these issues, a new format called DiffX is proposed. DiffX builds on Unified Diffs, adding structure and metadata while remaining compatible with existing tools.

Key Features of DiffX:

  • Standardized parsing rules for diffs.
  • Formal storage and naming of metadata.
  • Ability to represent multiple commits in one file.
  • Support for binary content and text encodings.
  • Compatibility with existing parsers and tools.

DiffX aims to enhance the diff experience without forcing tools to adopt a new format or causing disruption. It is designed to be future-proof and user-friendly.

If you're interested in learning more about the limitations of current diff formats or want to explore DiffX further, resources like the DiffX File Format Specification and example files are available.

(A new Pitt study has upended decades-old assumptions about brain plasticity)

A new study from the University of Pittsburgh challenges long-held beliefs about how the brain adapts and learns. Researchers found that the brain uses separate sites for different types of signals—spontaneous (random) and evoked (triggered by sensory input)—rather than relying on a single shared site. This discovery, led by Oliver Schlüter and published in Science Advances, suggests that the brain can stay stable while also being flexible enough to learn.

The study focused on the primary visual cortex, observing that while evoked signals strengthened with visual input, spontaneous signals plateaued, indicating different control mechanisms for each. This separation helps maintain consistent background activity while allowing the brain to develop pathways important for learning.

The findings may have significant implications for understanding disorders like autism and Alzheimer’s disease, as they provide insights into how normal signaling can become disrupted. Overall, the research highlights a key strategy the brain employs to balance stability and flexibility in its functions.
