The Art of Fugue – Contrapunctus I (2021)
(The Art of Fugue – Contrapunctus I (2021))

Summary of "The Art of Fugue – Contrapunctus I"

JS Bach's final work, The Art of Fugue, was published after his death but initially received little acclaim, selling only about thirty copies. It wasn't fully performed until 1922. The collection was designed for study rather than casual listening, which is why it can be challenging to enjoy. However, visualizing its structure can enhance the experience.

Contrapunctus I, the first piece, features a simple melody called the subject, and the voices interact around this melody without complex techniques. Unlike later pieces, it doesn't use advanced counterpoint methods. The music flows smoothly with mostly stepwise movements and avoids strong cadences, creating a mesmerizing effect.

Bach's use of "open score," where each voice is written on a separate line, allows for various interpretations and performances on different instruments. While Contrapunctus I may not seem complex, it explores musical ideas freely, similar to jazz in its improvisational feel.

To better appreciate the music, the author finds that adding a rhythmic beat helps maintain focus. The remix of Bach's work with contemporary beats can make it more engaging while still being educational.

Why Cline Doesn't Index Your Codebase (and Why That's a Good Thing)
(Why Cline Doesn't Index Your Codebase (and Why That's a Good Thing))

Cline, a tool for developers, does not index codebases using Retrieval Augmented Generation (RAG), which is a common method for AI systems to access large datasets. Instead, Cline takes a different approach that focuses on better code quality, security, and reliability. Here are the main points:

  1. Problems with RAG for Code:

    • Chunking Issues: RAG breaks code into chunks, losing the logical connections between parts, similar to understanding a symphony by listening to random clips.
    • Index Decay: Code changes frequently, making static indexes quickly outdated, leading to incorrect suggestions from AI tools.
    • Security Risks: Storing indexed code creates vulnerabilities, exposing valuable intellectual property.
  2. Cline's Method:

    • Structural Understanding: Cline starts by mapping the code structure using Abstract Syntax Trees, similar to how a developer familiarizes themselves with a new codebase.
    • Exploratory Reading: Cline reads the code in a connected manner, following imports and relationships, rather than retrieving random chunks.
  3. Benefits:

    • Cline produces high-quality context for tasks, leading to better, more relevant coding suggestions that fit the project's architecture.
    • It operates directly on the code stored on the user's machine, avoiding the need for vector databases.

Cline aims to utilize advanced language models to understand code like a developer would, focusing on intelligent exploration rather than traditional retrieval methods.

GitHub MCP exploited: Accessing private repositories via MCP
(GitHub MCP exploited: Accessing private repositories via MCP)

Summary of GitHub MCP Vulnerability

A serious vulnerability has been found in the GitHub MCP (Managed Code Pipeline) server, allowing attackers to access private repository data. This vulnerability was identified by Invariant's security tools and is one of the first cases of what they call "Toxic Agent Flows," where an agent is tricked into leaking sensitive information.

Key Points:

  • Attack Overview: Attackers can create malicious issues in a public repository that, when interacted with by the user, can cause their agent to unintentionally leak information from private repositories.
  • How It Works: If a user queries their agent for issues in a public repo, the agent can be manipulated to fetch and leak private data into a public pull request.
  • Impact: The method can lead to revealing sensitive information, such as proprietary code and personal data.

Detection and Mitigation:

  • No Need for Tool Compromise: The vulnerability arises from how agents handle untrusted information, not from flaws in the GitHub MCP server itself.
  • Mitigation Strategies:
    1. Granular Permissions: Limit agent access to only necessary repositories to prevent data leaks.
    2. Continuous Monitoring: Implement security scanners to audit interactions and detect potential threats in real-time.

Conclusion:

This vulnerability is a reminder that even well-aligned AI models can be manipulated. Organizations should adopt robust security practices to protect against similar vulnerabilities in their systems. For help securing agent systems, Invariant offers a security program for interested parties.

The Myth of Developer Obsolescence
(The Myth of Developer Obsolescence)

The text discusses the recurring hype around new technologies that promise to replace software developers, like NoCode, cloud computing, and AI-assisted development. Each time a new technology emerges, it generates excitement, but instead of eliminating jobs, it transforms them and creates new roles that often pay more.

  1. NoCode Movement: Initially thought to allow anyone to build apps without developers, it actually led to the rise of NoCode specialists who understand both business needs and technical aspects, often earning higher salaries than traditional developers.

  2. Cloud Computing: The expectation was that moving to the cloud would eliminate system administrators. Instead, their roles evolved into DevOps engineers, managing more complex systems and earning higher pay.

  3. Offshore Development: The promise of cheaper overseas labor faced challenges such as communication issues and quality control, leading to more complex team structures and often higher overall costs.

  4. AI-Assisted Development: AI is now seen as a tool that can write code, but it often produces errors that require experienced developers to correct. The real value lies in system architecture, which AI cannot handle effectively.

The key takeaway is that rather than replacing developers, new technologies elevate the need for specialized skills, particularly in system architecture, which remains a critical area that AI cannot replace. Code is seen as a liability that requires careful management, and as technology evolves, the role of software architects becomes increasingly important.

Outcome-Based Reinforcement Learning to Predict the Future
(Outcome-Based Reinforcement Learning to Predict the Future)

Reinforcement learning with verifiable rewards (RLVR) has improved math and coding in large language models, but it hasn't been widely used in real-world forecasting. A challenge is that forecasting often relies on binary, delayed, and noisy outcomes, making standard methods unreliable. This study shows that by adapting two algorithms, Group-Relative Policy Optimisation (GRPO) and ReMax, to the forecasting context, a 14 billion parameter model can achieve high accuracy and better prediction calibration.

Key improvements include:

  • Removing unnecessary variance in GRPO.
  • Using baseline-subtracted advantages in ReMax.
  • Training with 100,000 consistent synthetic questions.
  • Adding safeguards against nonsensical answers and missing explanations.

These adaptations allowed the model to handle 110,000 events effectively. The refined model matches the best accuracy benchmarks while outperforming in calibration. A simple trading strategy based on this calibration could potentially yield $127 in profit, compared to $92 from the best current model. This suggests that improved RLVR techniques can turn smaller language models into valuable forecasting tools, with potential for larger models in the future.

  • Streaming: Your device temporarily holds data in a buffer to play it but doesn't save it permanently.
  • Downloading: Your device saves the data as a file for permanent access.

When streaming, the media is typically sent in chronological order, and the server can adjust the quality based on your connection. Streaming often comes with digital rights management (DRM) to prevent users from saving copies of the media, while downloads are usually higher quality and can come in any order.

In essence, all streaming involves downloading, but the expectation is that streamed content is not retained after viewing. Users can still find ways to save streamed media, which raises questions about the effectiveness of restrictions placed by streaming platforms.

SVG favicons in action
(SVG favicons in action)

This article discusses how to create SVG favicons, which are small icons displayed in browser tabs. SVG (Scalable Vector Graphics) favicons have advantages over traditional formats like PNG, including scalability and compactness. One key benefit of using SVG favicons is their ability to support dark mode, allowing the icon to change based on the browser's theme.

To create an SVG favicon with dark mode support, you can use CSS within the SVG file to define styles for light and dark themes. This involves writing CSS code manually, which can be challenging because SVG files can be complex.

The article explains that favicons should generally be simple versions of your website's logo, ensuring they fit well in the small space of a tab. When logos are designed for light backgrounds, they may need adjustments for dark mode, such as increasing brightness or inverting colors.

For convenience, the author introduces an online tool called the SVG favicon editor, which simplifies the process of generating favicons by allowing users to upload their logos and easily apply the necessary adjustments for both light and dark modes.

In conclusion, while SVG favicons are underused, they offer unique benefits, particularly for websites with dark mode features. With the right tools and techniques, creating effective SVG favicons can be quick and easy.

A new class of materials that can passively harvest water from air
(A new class of materials that can passively harvest water from air)

Researchers at Penn Engineering have discovered a new type of material that can extract water from the air without using any external energy. This innovative material, made of nanostructured components that combine water-attracting and water-repelling properties, collects moisture from the air and releases it as droplets.

The discovery happened unexpectedly while the team was experimenting with different materials. They found that unlike typical porous materials where water gets trapped, their material allows water to move and form droplets on the surface. This process works even in low humidity conditions, using a method called capillary condensation.

The researchers were surprised to see that the water droplets remained stable for a long time, contrary to usual expectations. They believe the material's unique structure creates a cycle where water is continually replenished from the air, making it effective for passive water collection in dry areas.

The simplicity of this material, made from common polymers, means it could be used in various applications, such as water harvesting devices, cooling electronics, or smart surfaces that respond to humidity. The team plans to further optimize this technology to make it practical for real-world use, aiming to provide clean water in arid regions and develop more sustainable cooling solutions.

Why console makers can legally brick your game console
(Why console makers can legally brick your game console)

Summary

Console makers like Nintendo, Sony, and Microsoft have the legal right to "brick" (permanently disable) your gaming console if you violate their end-user license agreements (EULAs), such as by hacking or using pirated software. Nintendo recently updated its EULA to allow this, prompting criticism. Sony and Microsoft have similar clauses in their agreements that permit them to disable consoles for rule violations.

While companies usually only ban consoles from online services, they can technically disable offline functionality as well. However, this practice is rare. Although they have the legal authority, console makers often do not use this power, possibly due to concerns about public backlash.

Legal experts believe that while users own the hardware, the software is licensed, allowing companies to enforce these rules. Many consumer advocates argue that users should have the right to modify their devices without fear of punishment like bricking.

In summary, while console makers can legally brick devices for EULA violations, they rarely do so in practice, likely to avoid negative public reactions.

Changelog: Lazy trees (faster Nix builds)
(Changelog: Lazy trees (faster Nix builds))

Lazy trees are a new feature in Determinate Nix version 3.5.2, designed to improve efficiency in large repositories, especially monorepos. They allow for faster and less resource-intensive evaluations by copying only the necessary files instead of the entire source tree. This can lead to significant reductions in evaluation time and disk space usage, with some users experiencing up to 3 times faster evaluations and 20 times less disk usage.

To use lazy trees, users need to enable them in their Nix configuration. The feature is currently available on an opt-in basis, and the team is working on integrating it into the upstream Nix.

In tests, using lazy trees has shown notable improvements:

  • Evaluating a package like "cowsay" without lazy trees took about 11 seconds and used 433 MB of disk space, while with lazy trees, it took only 3.5 seconds and used just 11 MB.

Users should be aware of potential warnings regarding inefficient file copying. The team has provided guidance on how to specify sources to avoid these inefficiencies.

For those interested in trying lazy trees in CI environments like GitHub Actions, specific configurations are available. Users can easily upgrade or install Determinate Nix to access this feature.

The team plans to continue enhancing Nix’s performance with future updates, aiming for better evaluation caching and parallel processing capabilities.

TIL: timeout in Bash scripts
(TIL: timeout in Bash scripts)

Summary: Using Timeout in Bash Scripts

In Bash scripts, the timeout command can help prevent infinite loops when waiting for a process, like a web server, to start.

In a script, you might use until to check if the server is up, but if the server fails to start, the script could get stuck in an infinite loop. For example:

until curl --silent --fail-with-body 10.0.0.1:8080/health; do
    sleep 1
done

To avoid this, you can use timeout, which limits how long a command can run. If the time limit is exceeded, it sends a signal to terminate the command.

However, timeout cannot be directly used with until because until is a shell built-in command. Instead, you can wrap the until command in a Bash process like this:

timeout 1m bash -c "until curl --silent --fail-with-body 10.0.0.1:8080/health; do
    sleep 1
done"

Alternatively, you can create a separate script for the until loop and use timeout on that script:

Scheming a mise-en-abîme in BQN
(Scheming a mise-en-abîme in BQN)

This text discusses the creation of an interpreter for a subset of the Scheme programming language, inspired by Peter Norvig's essay. The author prefers using a different implementation style, citing the elegance of a non-Lisp host. The goal is to follow the R5RS standard, although the interpreter is not fully compliant yet.

Key points include:

  • The interpreter uses BQN (a programming language) to define utilities and a global environment with Scheme primitives as functions.
  • The interpreter is designed as a modifier to support variations in the input environment.
  • It lacks proper error handling and has more lines of code compared to similar implementations, but includes important metaprogramming features.
  • The author tests the interpreter with a quine (a self-replicating program) and checks its compliance against a favorite Scheme implementation.
  • The final section invites readers to find any errors in the interpreter and acknowledges formatting challenges in the text.

Overall, this is a learning exercise in building a Scheme interpreter using BQN, with an emphasis on simplicity and functionality.

Demonstrating end-to-end scientific discovery with Robin: a multi-agent system
(Demonstrating end-to-end scientific discovery with Robin: a multi-agent system)

Today, we introduced Robin, our new multi-agent system designed to automate scientific research. Robin combines previous AI agents—Crow, Falcon, Owl, Phoenix, and Finch—into one system to streamline the entire scientific discovery process.

Our first major achievement with Robin was identifying ripasudil, a drug used for glaucoma, as a potential treatment for dry age-related macular degeneration (dAMD), a serious cause of blindness. This discovery was made through a series of steps:

  1. Hypothesis Generation: Robin used Crow to review literature and formed a hypothesis about enhancing retinal pigment epithelium (RPE) phagocytosis for dAMD treatment.
  2. Experimental Design: Falcon evaluated several molecules, leading to lab tests on ten candidates. Finch analyzed the results and found that a ROCK inhibitor increased RPE phagocytosis.
  3. Mechanism Investigation: Robin suggested further experiments to explore how the ROCK inhibitor affected gene expression in RPE cells, identifying key changes.
  4. Final Discovery: Using data from initial tests, Robin proposed more drug candidates, ultimately identifying ripasudil as a promising option for treating dAMD.

The entire process took just 2.5 months, showcasing how quickly Robin can operate. While our first focus was on therapeutics, Robin’s capabilities can apply to many scientific fields. We will release Robin as open-source on May 27th, aiming to inspire others to create their own automated discovery systems.

(Sleep apnea pill shows striking success in large clinical trial)

A recent clinical trial showed promising results for a new pill, AD109, that could help people with obstructive sleep apnea (OSA) replace the cumbersome CPAP machines currently used for treatment. OSA affects millions globally and can lead to serious health risks. The pill combines two existing medications that work together to keep the airway open during sleep by stimulating the necessary muscles.

In the trial involving 646 participants, those taking AD109 had 56% fewer breathing disruptions at night, and 22% achieved complete control of their sleep apnea, meaning fewer than five airway blockages per hour. The treatment also improved blood oxygen levels, which is crucial for heart health.

While experts are excited about these results, they still have questions about the drug’s overall impact on symptoms like daytime sleepiness and the long-term risks of OSA. Concerns about potential side effects from one of the medications used in AD109 were also raised. However, many believe this development could lead to more personalized treatment options for sleep apnea, moving away from a one-size-fits-all approach. The full trial results will be presented later this year, and there are plans for further research.

Grammars of Formal Uncertainty
(Grammars of Formal Uncertainty)

Large language models (LLMs) can help create formal specifications, but there’s a challenge: LLMs are probabilistic, while formal verification needs certainty. This paper explores the problems and uncertainties in LLM-generated formal documents. The study evaluates five advanced LLMs and finds that using Satisfiability Modulo Theories (SMT) improves accuracy for logical tasks by 34.8% but worsens factual tasks by 44.5%. Traditional uncertainty measurement methods, like analyzing token probabilities, do not effectively catch these errors. To improve this, the authors propose a new framework using probabilistic context-free grammar (PCFG) to better understand LLM outputs and their uncertainties, which vary by task. By combining different uncertainty signals, they can significantly reduce errors (by 14-100%) while maintaining high reliability in LLM-driven formalization.

The author is working on a scripting language for a fantasy console project and recognizes the need for a module system to manage public and private declarations. Currently, all code is in a single global space. The author explores different ways to handle access control, referencing existing languages like Java, C++, Python, Go, and Dart.

Key points include:

  1. Module System Basics: Each file has its own scope, and modules can encapsulate internal declarations that should remain private.

  2. Access Control Approaches:

    • Modifier Keywords: Common in languages like Java and C#, these are explicit but can be verbose.
    • Modifier Sections: Used in C++, allowing a keyword to apply to multiple declarations, but can be confusing regarding access rights.
    • Sigils in Names: Languages like Python and Go embed access levels in names (e.g., leading underscores), which can be terse but obscure.
    • Export Manifests: A separate section listing public declarations, which is clear but verbose and requires manual syncing with declarations.
  3. Current Considerations: The author leans towards a default public access control, with a simpler way to indicate private declarations. They are considering ideas such as alternate keywords or using a leading underscore to denote privacy.

  4. Final Thoughts: The author is weighing the pros and cons of each approach while aiming for clarity and ease of use in their new language. They are also open to feedback on their ideas for syntax.

The bad science behind expensive nuclear
(The bad science behind expensive nuclear)

On May 23, 2025, President Trump signed four executive orders aimed at promoting nuclear power in the U.S. One order requested that the Nuclear Regulatory Commission (NRC) re-evaluate the Linear No Threshold (LNT) model, which suggests that any level of radiation exposure increases cancer risk without a safe threshold. This model underlies nuclear safety regulations globally, yet it remains largely unknown to the public.

The text discusses a case from 2013 where GE Hitachi proposed building three advanced nuclear reactors in the UK, which faced extensive regulatory demands despite a strong safety record. The UK's Office for Nuclear Regulation required costly design changes to reduce radiation discharges by an extremely small amount, showing how regulatory standards can inflate costs unnecessarily.

The LNT model has deep historical roots, stemming from research in the 1920s that linked radiation exposure to genetic mutations. Despite some scientists questioning LNT's validity, it became the prevailing belief, influencing strict radiation safety regulations. Critics argue that this model is overly simplistic and does not account for the body's ability to repair damage from low doses of radiation over time.

The text details the historical context of nuclear regulation, including major incidents like nuclear weapons tests and their impact on public perception of radiation. Over time, regulatory bodies, particularly the AEC, faced growing criticism for downplaying health risks associated with radiation, leading to the establishment of the NRC, which adopted more stringent safety standards.

The narrative concludes that while the scientific community still largely supports LNT, emerging evidence suggests that low doses of radiation may not pose the same risks as high doses. The ongoing reliance on LNT and the ALARA (As Low As Reasonably Achievable) principle in regulatory practices is seen as a major factor driving up nuclear power costs and complicating the energy transition. Critics argue that this regulatory framework constrains investment in nuclear energy, which is critical for addressing global energy demands.

The thesis by Rohan Sawhney, titled "Monte Carlo Geometry Processing: A Grid-Free Approach to Solving Partial Differential Equations on Volumetric Domains," focuses on improving how complex partial differential equations (PDEs) are solved, particularly in geometrically intricate areas. Traditional methods often require creating detailed volumetric meshes, which can be time-consuming and inefficient on modern computers.

Sawhney introduces a new algorithm based on the "walk on spheres" (WoS) method, which reformulates the problem into recursive integral equations. This approach allows for the use of Monte Carlo methods, avoiding the need for mesh generation and enabling easier handling of complex geometric data. The proposed methods benefit from the characteristics of Monte Carlo rendering, such as parallel processing and the capability to efficiently evaluate PDE solutions without solving large systems of equations.

The research aims to provide more robust and scalable solutions for scientists, engineers, and designers working with complicated geometric data. The thesis also acknowledges various contributors and collaborators who supported Sawhney throughout his PhD journey.

Violating memory safety with Haskell's value restriction
(Violating memory safety with Haskell's value restriction)

The text discusses a potential memory safety issue in Haskell related to polymorphic references in impure languages. Here's a simplified summary of the key points:

  1. Polymorphic References: In languages that allow both polymorphism and mutable references, like a hypothetical impure language, one could create unsafe polymorphic references that violate type safety.

  2. Value Restriction: This issue is often mitigated by a rule called the value restriction, which prevents certain expressions from being generalized to polymorphic types unless they are "values" (i.e., expressions that do not perform computations).

  3. Haskell's Approach: Unlike some other languages, Haskell does not have a strict value restriction in its let bindings. However, when the text's unsafe code is translated to Haskell, it produces a type error instead of being unsafe, due to Haskell's handling of monadic bindings.

  4. Monadic Bindings: In Haskell, the way monadic operations are structured prevents the unsafe generalization of types, keeping the code safe. The type of the result in monadic operations remains monomorphic, which avoids the memory safety issues.

  5. Generalizable Monads: The author explores if other monads, like the Identity monad, can allow generalization in a safe way. They propose a type class, MonadGen, that can enable generalization for certain monads safely.

  6. State Monad: The State monad in Haskell is shown to allow generalization, unlike the IO monad. The internal structure of IO is unique, making it challenging to implement MonadGen for it.

  7. Unsafe Unwrapping: The conclusion emphasizes that despite Haskell’s purity, it still needs mechanisms to prevent unsafe type generalizations similar to the value restriction found in other languages. Unwrapping the IO constructor can lead to memory safety violations.

Overall, the key takeaway is that Haskell's handling of monadic types helps maintain memory safety, but certain operations, especially with IO, require careful management to avoid unsafe scenarios.

Having your compile-time cake and eating it too
(Having your compile-time cake and eating it too)

Summary of "Having your compile-time cake and eating it too" by Derin Eryılmaz

This post discusses how programming languages can effectively balance compile-time features with user-friendly type systems, focusing on Rust and Zig.

  1. Type Systems: Type systems help prevent runtime errors by ensuring that values have the correct types before the program runs. In Zig, types are treated as values, allowing for complex compile-time operations, which can lead to confusing type signatures.

  2. Human-Friendly Type Systems: The Hindley-Milner (HM) type system, used by languages like Rust and Haskell, treats types as abstract constructs. This simplifies type reasoning, eliminates arbitrary logic in type signatures, and supports strong type inference.

  3. Compile-Time Execution: The post proposes that variables known at compile-time should be tracked separately from the type system. Programmers should explicitly indicate when to run functions at compile-time to maintain clarity.

  4. Types and Type Objects: Types should not be treated as values, as doing so complicates type reasoning. The author suggests separating a type's structure from its identity while allowing types to be referenced logically in code.

  5. Code Objects: The concept of code objects allows manipulation of source code at compile-time. This enables powerful features, such as generating functions or checking the validity of regex patterns before runtime.

  6. Metaprogramming: The author introduces ways to automate common tasks, like generating string representations for types or summing fields in structs, without complicating the type system.

  7. Conclusion: The ideas presented aim to combine the best features of Rust and Zig, providing a framework for a language that retains the simplicity of HM while offering advanced compile-time capabilities. The author encourages others to explore these concepts further.

Overall, the post emphasizes the importance of maintaining a balance between powerful compile-time features and a clear, understandable type system for programmers.

The list, part of content provided by King Features, includes only five real titles out of fifteen. Writer Marco Buscaglia has admitted that the list was generated partly by Artificial Intelligence and takes full responsibility for its inaccuracies.

Readers expressed frustration on social media, questioning the value of subscribing to newspapers that include misleading content. Chicago Public Media, the parent company of the Sun-Times, is investigating how this occurred and emphasized the importance of providing accurate information to their audience.

The incident highlights broader issues in the media industry, including the decline of professional book reviewers and the potential risks of AI-generated content. Some writers are considering legal action to protect their work from being misrepresented by AI.

(Now you can watch the Internet Archive preserve documents in real time)

The Internet Archive has launched a new YouTube livestream that shows how they digitize microfiche in real time. Microfiche are sheets of film containing miniaturized documents, often used for storing historical records. The livestream gives viewers a close-up look at the digitization process at their Richmond, California location, where operators use high-resolution cameras to capture images of microfiche cards. Software then stitches these images together, making them searchable before they are uploaded to the Archive's online collections. The livestream runs Monday to Friday from 10:30 AM to 6:30 PM ET, and during off hours, it features other content from the Archive, such as public domain films and historical NASA images.

Dependency injection frameworks add confusion
(Dependency injection frameworks add confusion)

The text discusses the use of Dependency Injection (DI) in Go programming, highlighting the pros and cons of using DI frameworks versus manual dependency management.

Key Points:

  1. Understanding Dependency Injection (DI):

    • DI is simply a technique for passing dependencies (like databases) to constructors rather than creating them within the constructors. This makes code more flexible and testable.
  2. DI Frameworks vs. Manual Wiring:

    • Many developers find DI frameworks cumbersome due to their complexity and reliance on reflection, which can lead to hard-to-trace runtime errors.
    • A manual wiring approach, where dependencies are explicitly created and passed, is often clearer, easier to debug, and allows for better compile-time error checking.
  3. Example of Manual Wiring:

    • The text provides an example of manually wiring dependencies in Go, showing how it allows for clear error messages and control over the dependency graph.
  4. Trade-offs of Using DI Frameworks:

    • Frameworks can simplify dependency management in large applications but may introduce additional complexity and a learning curve. They often require a shift in mindset and vocabulary.
    • In contrast, manual wiring keeps the code straightforward and understandable.
  5. When to Use a DI Framework:

    • While the author generally finds DI frameworks add confusion, they acknowledge there might be scenarios (like large-scale applications) where frameworks can be beneficial if the team is equipped to handle their complexities.

In summary, the text advocates for manual dependency management in Go for its clarity and simplicity while recognizing that DI frameworks may have their place in certain contexts.

'Strange metals' point to a whole new way to understand electricity
('Strange metals' point to a whole new way to understand electricity)

In Silke Bühler Paschen's lab at the Vienna University of Technology, researchers are investigating "strange metals," which behave unusually when conducting electricity. Unlike regular metals, strange metals show a resistivity that increases linearly with temperature, and they lose electrical resistance altogether at low temperatures, becoming superconductors. This phenomenon has puzzled physicists for decades, as it contradicts the standard theory of electricity, which treats electrons as independent particles.

Recent experiments suggest that in strange metals, electrons lose their individuality and behave more like a collective "soup" rather than distinct entities. This challenges the traditional understanding of how electricity flows and raises questions about the very nature of particles and charge carriers. Some physicists believe that finding a theory to explain strange metals could lead to breakthroughs in superconductivity, potentially paving the way for room-temperature superconductors that could transform technology.

Research indicates that strange metals might be governed by quantum entanglement, where properties of particles are linked. Several theories are emerging, with scientists proposing different mechanisms behind the strange behavior of these metals. The ongoing exploration aims to better understand these materials and their implications for both fundamental physics and practical applications in technology.
