Summary: Parsing JSON in Awk

The text discusses the challenges of parsing JSON in a Unix shell environment using Awk, a programming language available in the POSIX shell. JSON's hierarchical structure makes it difficult to split on any character, unlike HTML. While tools like jq and programming languages like Python are better suited for JSON parsing, the author had a working shell script that needed JSON support.

The author created a concise JSON parser in Awk, which assumes valid JSON input from a trusted source. The parser includes a simple function that retrieves values from JSON objects or arrays based on a provided key path.

Key points:

• The function can handle both arrays and objects and returns the corresponding value.
• Basic validation is included, but it does not guarantee complete error handling.
• A decoding function for JSON strings is provided, which handles most escape sequences except for Unicode.
• An error handling function is also included to manage errors in parsing.

Overall, the article shows how to implement a basic JSON parser in Awk in a straightforward manner.

The text discusses the importance of properly seeding random number generators (RNGs) in C++, focusing on the use of std::seed_seq introduced in C++11. Here are the key points summarized:

1. Poor Seeding Practices: Many developers use low-quality seeds like system time or process IDs, which can lead to predictable and biased random outputs.

2. C++11 vs Other Languages: Unlike languages like JavaScript and Python that handle good seeding automatically using the operating system’s randomness, C++ requires specific methods to seed RNGs.

3. Using std::seed_seq: This class is intended to improve seed quality, but it can create problems if used improperly. For example, initializing an RNG like Mersenne Twister with just one 32-bit integer reduces the possible states to about 4 billion, making it easier to predict future outputs.

4. Predictability and Bias: Using a single integer can lead to predictable outcomes and biases in RNG outputs, which can have significant consequences in applications like gaming or data sampling.

5. Example Scenario: The text presents a hypothetical situation involving the Twitter app, where developers used poor RNG practices, leading to unexpected outcomes and data collection issues.

6. Limitations of std::seed_seq: The std::seed_seq can introduce bias even when multiple good seeds are provided, as it doesn’t always guarantee a unique mapping from input seeds to RNG states.

7. Recommendations: The author suggests that if you need to seed an RNG with a more complex internal state, you should provide enough seed randomness, ideally equal to the internal state size. Additionally, C++ should improve its RNG seeding methods in future updates.

8. Conclusion: Proper seeding is crucial for the reliability of random number generation in C++. Developers should be cautious about how they seed their RNGs to avoid biases and predictability.

Overall, the author emphasizes the need for better practices and improvements in C++’s RNG seeding mechanisms.

Joan Westenberg recently deleted all her notes, ideas, and thoughts accumulated over seven years, which she had stored in various productivity tools. Initially, she built what is known as a "second brain" to capture and organize her thoughts, believing it would provide clarity and control. However, over time, this system became overwhelming and stifled her curiosity, turning into a collection of outdated thoughts that no longer served her.

Reflecting on her journey of sobriety, she realized that the insights and growth she achieved were not found in her notes, but through lived experiences. She argues that the modern approach to personal knowledge management can lead to confusion rather than understanding, as it encourages storing ideas instead of actively engaging with them.

Westenberg emphasizes that human memory is dynamic and contextual, rather than a static archive. She critiques the anxiety surrounding unread lists and the false belief that merely naming a goal brings you closer to achieving it. Instead, she advocates for a more minimalist approach to knowledge, where deletion and letting go can lead to a clearer mind and greater presence.

Ultimately, she aspires to live in the moment, write freely, and trust that important ideas will resurface naturally, rather than attempting to manage everything. She plans to restart her note-taking with a more intentional and curated approach, focusing on her current thoughts rather than maintaining a vast archive.

Meta, the company behind Facebook, is exploring the use of private, unpublished photos from users' camera rolls to enhance its AI features. Although they currently claim not to be training their AI models on these photos, they have introduced a feature that allows users to opt into "cloud processing." This feature would enable Facebook to access and analyze images from users' devices to create suggestions for sharing, such as collages or themed content.

Users must opt in to this feature, which comes with terms that grant Meta permission to analyze personal details from those photos. While Meta insists that this is just an early test and does not involve training AI on unpublished photos, there is ambiguity about how long they might retain this data and whether it could be used in the future.

Importantly, users can turn off this cloud processing option, which would stop the access to their unpublished photos. However, some reports suggest that Meta may already be using AI suggestions on previously uploaded photos without user consent. Overall, this development raises concerns about privacy and the handling of personal data by tech companies.

The text discusses the evolving landscape of antitrust laws and activism, emphasizing that economic elites disproportionately influence U.S. policy, as highlighted by a study from 2014. The author, Cory Doctorow, expresses frustration with the political system that often caters to billionaires' interests over those of average citizens. However, there has been a recent global surge in antitrust enforcement, led by the EU and supported by countries like Australia and Canada, challenging the dominance of big tech companies.

Doctorow notes that both progressive and conservative political parties have historically supported monopolies, but the current wave of antitrust activity is seen as a rare political shift favoring the public. He attributes this change to widespread discontent with the political system, suggesting that as people seek alternatives to entrenched power, there is potential for significant societal change. The article concludes with a sense of hope, highlighting unexpected political victories and a growing demand for reform.

Business Insider shares interesting and innovative stories that readers want to learn about.

The article titled "Structuring Arrays with Algebraic Shapes," authored by Jakub Bachurski, Alan Mycroft, and Dominic Orchard, was published in the proceedings of the ARRAY '25 workshop. It discusses a new type system called Star, designed for array programming languages. Most current type systems in this area are either very limited or overly complex, often leading to errors or undecidable problems.

Star introduces a better way to handle array indices and shapes by using structural record and variant types with subtyping. This approach aims to reduce indexing errors by allowing programmers to explicitly define the structure of arrays, which enhances type safety and optimization without resorting to complex dependent types.

The paper highlights the advantages of having richer types for arrays, making programming in fields like data science and machine learning more reliable and efficient.

The article discusses whether the focus on British royalty overshadows a true understanding of the country's history. It questions if the emphasis on kings and queens helps or hinders our grasp of historical events and cultural developments, such as architecture and literature, which are often linked to specific monarchs. The author, Levi Roach, a Medieval History professor, warns that relying too much on traditional periods defined by monarchs can distort our understanding of British history.

Researchers from Lawrence Berkeley National Laboratory, UC Irvine, and the University of Illinois Urbana-Champaign have developed a way to turn human urine into a useful product by modifying yeast. They engineered a strain of yeast called Saccharomyces boulardii, nicknamed “osteoyeast,” to convert nutrients in urine into hydroxyapatite, a mineral essential for making bones and teeth. Hydroxyapatite is valuable in surgery and dentistry and could also replace some plastics.

This innovative method not only offers a cheaper way to produce hydroxyapatite but also helps reduce wastewater treatment costs and creates a new source of fertilizer from urine. The yeast can efficiently produce hydroxyapatite at a low cost, with estimates suggesting it could be profitable to produce it for around $19 per kilogram, while it can be sold for up to $200.

The project emphasizes collaboration between different scientific disciplines, combining biology and materials science to track the entire hydroxyapatite production process. The researchers are also exploring further applications for their engineered yeast, which could lead to environmentally friendly bio-mining and the creation of other bio-based materials.

For licensing the osteoyeast technology or more information, contact the Berkeley Lab Intellectual Property Office.

Positional encodings are essential for transformer models, allowing them to handle sequential data without needing recurrence. This paper examines different methods of positional encoding—like sinusoidal, learned, relative, and bias-based methods (such as ALiBi)—and how they affect a transformer's ability to express functions, generalize knowledge, and handle longer sequences. The authors introduce new encoding methods based on orthogonal functions, like wavelets and Legendre polynomials, and analyze their performance. They find that these new methods perform better than traditional sinusoidal encodings in terms of generalization and extrapolation. This research fills an important gap in transformer theory and offers valuable insights for applications in areas like natural language processing and computer vision.

Summary: Programming as Theory Building: Why Senior Developers Are More Valuable Than Ever

Peter Naur's essay from 1985, "Programming as Theory Building," emphasizes that programming is about creating a shared understanding of how systems work, rather than just writing code. This understanding, or "theory," is crucial because once experienced developers leave, the context and rationale behind the code often disappear, leading to "theory-less" code.

Today, many junior developers rely heavily on AI tools to generate code without fully understanding it. This can lead to problems, as they might introduce code that doesn't fit the system's architecture or domain, creating technical debt and confusion in codebases.

Senior developers are vital in this environment because they:

1. Build Domain Theories: They connect business needs with software architecture, understanding why code exists and how it should evolve.
2. Guard Architectural Integrity: They assess whether new code aligns with existing theories and conceptual frameworks.
3. Collaborate Intentionally with AI: They use AI thoughtfully, ensuring that generated code aligns with the system's needs rather than blindly accepting it.
4. Mentor Junior Developers: They teach the importance of understanding and problem-solving, helping to cultivate deeper programming skills.

The essence of programming lies in human understanding and theory building, which AI cannot replicate. To maintain software quality, organizations must focus on preserving this human element through effective documentation, knowledge sharing, and mentorship. In a landscape dominated by AI, senior developers will continue to be essential for creating coherent and meaningful software systems.

Summary:

Justin Fagnani proposes adding a declarative templating API to the web platform. The current DOM API lacks a built-in way to create and manage dynamic DOM nodes efficiently, which is a critical feature in modern web development frameworks like React and Vue. Templating enhances developer experience by making code easier to write and read, improving security against attacks, and optimizing performance.

The absence of a native templating solution leads to longer app loading times, reliance on third-party libraries, and difficulties in developer tools. Competing platforms already offer templating-like systems, making it essential for the web platform to adapt.

Fagnani believes that now is a good time to revisit templating due to advancements in framework technologies and the growing demand from developers. Existing JavaScript features, like tagged template literals, can facilitate this without needing new syntax.

The proposal aims to create a templating API that is efficient, easy to use, and can coexist with existing frameworks. This API would benefit developers and users, and serve as a stepping stone towards more comprehensive templating solutions in the future. Fagnani is looking for collaboration on this proposal.

The article discusses a new rule in C23 that allows for better compatibility of structs, unions, and enums defined in different translation units (TUs). Previously, each definition was treated as a distinct type, but now they are considered compatible if they have the same name and structure. This change enables the use of parameterized types with macros.

For example, a Slice type can be defined using a macro, allowing for dynamic creation of slice types for different data types. This means you can declare functions that use slices parameterized by element types without needing to define each type ahead of time.

However, there are limitations. For instance, defining complex structures like a Map requires generic functions, which aren't fully supported with this new rule. Additionally, there are complications when trying to use slices of slices due to naming conventions in the macro.

Overall, while this new feature simplifies some aspects of type management in C, it also comes with trade-offs and limitations that need to be considered. A demo of the technique is available for those interested in seeing it in action.

The author discusses the slow build times of their Rust website when using Docker. Currently, they build a new Rust binary for every change, which takes about 4 minutes, including downloading dependencies. This process is inefficient, especially compared to faster local builds.

To improve build speed, they explore using Docker with better caching methods. They mention a tool called cargo-chef, which allows pre-building dependencies and caching them, so only the changed code needs recompiling. However, they still face long build times for the final binary, with most of the time spent in that step.

The author investigates what the Rust compiler (rustc) is doing during the build process using timing reports. They find that their final build takes around 2 minutes and 54 seconds, and they aim to analyze the build process further to identify areas for improvement.

In summary, the author is looking for ways to speed up their Rust builds in Docker, mainly focusing on caching dependencies and analyzing compiler performance to reduce build times.

The author shares their experience of automating home lighting using Bash and Zigbee technology. They wanted smart lights that could be controlled remotely and adjusted in color temperature throughout the day. After deciding on Zigbee hardware, they used Zigbee2MQTT software to connect their devices and expose them over the MQTT protocol.

Instead of using complex home automation software, the author created a simple program called MQTTR to handle MQTT messages. They wrote scripts in Bash to control the lights based on messages from their light switches and dimmers. This setup allowed them to toggle lights and manage brightness and color temperature effectively.

The author also integrated their system with an Android app, MqttDroid, but faced challenges due to its limitations in handling JSON messages. They overcame this by creating additional Bash scripts to mirror the state of the lights in a format compatible with MqttDroid.

In summary, the project involved using Bash to build a flexible home lighting automation system that allows control through physical switches, dimmers, and a mobile app. The author is pleased with the results, although some features, like progressive color temperature changes, are still to be implemented.

Summary of Bypassing Ubuntu’s Unprivileged Namespace Restriction

In June 2025, a researcher revealed that Ubuntu's new sandboxing features, aimed at improving security by restricting unprivileged user namespaces, could be bypassed more easily than anticipated. Initially, Ubuntu's implementation seemed robust, designed to prevent untrusted applications from creating unprivileged namespaces, which historically allowed attackers access to significant system vulnerabilities.

Key Points:

1. Ubuntu's Sandbox Introduction: In April 2024, Ubuntu announced new security measures to control unprivileged namespaces through AppArmor, aiming to enhance security after years of being targeted by attackers.

2. Discovery of Bypass: The researcher discovered a method to bypass these protections shortly after hearing about a potential loophole. However, the timing coincided with Pwn2Own 2025, where Ubuntu was no longer a target, making the discovery less relevant for competition.

3. Vendor Response: After reporting the bypass to the Zero Day Initiative (ZDI) and facing delays, the researcher eventually reported the issue directly to the Ubuntu Security Team, who acknowledged the problem and confirmed it aligned with other known vulnerabilities.

4. Technical Details: The bypass involved manipulating AppArmor profiles. By switching the process’s profile to another unconfined one, the restrictions blocking the creation of unprivileged namespaces could be circumvented.

5. Mitigation: The bypass only functions if a specific setting (/proc/sys/kernel/apparmor_restrict_unprivileged_unconfined) is disabled, which has been set to enabled by default in Ubuntu versions after 25.04.

6. Disclosure Timeline: The timeline of events from the discovery of the bypass to its coordinated public disclosure outlines the back-and-forth communication with security teams and the eventual resolution.

This summary highlights how even seemingly secure systems can have vulnerabilities and the importance of continuous security research and feedback loops between researchers and vendors.

Summary: How Much Slower is Random Access?

The article discusses the impact of accessing array elements in different orders (first-to-last vs. random) on performance in computer programs. Here are the key points:

1. Locality of Reference: Programs should be designed to take advantage of memory locality to improve performance, as modern computers have multiple levels of cache (L1, L2, L3).

2. Performance Comparison: The author uses a sample program to sum floating-point numbers in two ways: in order and randomly. Key questions include:

   • When does performance differ based on access order?
   • How much slower is random access compared to sequential access?

3. Data Generation: Random data is generated using a standard method (Fisher-Yates shuffle). However, for large datasets that don't fit in memory, a more efficient two-pass shuffle is used.

4. Experimental Setup: The experiments are conducted on two machines: a MacBook Pro and a Linux desktop, measuring the time taken to sum numbers under different conditions and orders.

5. Results:

   • For small arrays (under a million elements), there's little performance difference.
   • When arrays exceed cache size, random access can be 4 to 16 times slower on different systems.
   • For very large arrays (over a gigabyte), performance degrades significantly, especially on Linux.
   • Memory-mapped files do not significantly improve performance compared to directly accessing files.

6. Conclusions:

   • Access order greatly affects performance, particularly for larger datasets.
   • Using a two-pass shuffle is better for large datasets.

A new type of tetrahedron, a geometric shape with four triangular faces, has been developed that can only rest on one specific face. This discovery confirms a theory proposed by mathematician John Conway decades ago.

In 1966, Conway and Richard Guy questioned whether a stable tetrahedron made of uniform material could be designed to balance on just one face. They initially concluded it was impossible, but later research allowed for uneven weight distribution. Gábor Domokos and his team proved this was feasible and created a physical model of a tetrahedron that flips to its stable side.

The tetrahedron, made from lightweight carbon fiber and dense tungsten carbide, had to be crafted with extreme precision. After overcoming initial failures, the team succeeded in constructing a model that works as intended. This innovative shape could have practical applications, such as in designing self-righting spacecraft.

The research emphasizes the importance of experimentation in mathematics and could lead to further insights into the properties of polyhedra.

The U.S. Supreme Court has ruled to limit the power of federal judges to issue nationwide injunctions that block presidential orders, including Donald Trump's attempt to ban birthright citizenship. This decision allows court orders to apply only to the specific plaintiffs involved in a case, rather than halting policies across the entire country.

While the court did not immediately implement Trump’s policy on birthright citizenship, it has created uncertainty about the future of this policy, which aims to deny citizenship to children born in the U.S. to parents without legal immigration status. Advocacy groups are responding by adjusting their legal strategies to challenge the policy.

The ruling was decided by a 6-3 vote, with the conservative justices supporting the Trump administration. Trump celebrated the ruling as a victory for his agenda, while dissenting liberal justices warned that it threatens the rule of law by allowing unconstitutional policies to affect those who haven't sued in court.

Birthright citizenship has been protected by the 14th Amendment since 1868, and many fear that this ruling could lead to enforcement of Trump's controversial policies, creating anxiety among immigrant families. While the decision has been criticized as legally flawed, some Democratic attorneys general emphasized that birthright citizenship remains the law.

Health departments across the U.S. are facing significant delays in funding from the Centers for Disease Control and Prevention (CDC), leading to layoffs and disruptions in public health services. The CDC has not received its full budget for the 2025 fiscal year, causing grants to be months late. Many state health departments rely heavily on this federal funding, with some states getting over 60% of their budget from the CDC.

Without timely grants, health departments are unable to continue critical programs. For example, Ohio's HIV prevention services and contact tracing efforts in North Carolina have been halted, leading to job losses and increased risks of disease spread. The CDC is currently operating with only 30 days of funding at a time due to bureaucratic delays, which has been described as "impounding" their budget.

Despite a continuing resolution from Congress allocating $9 billion to the CDC, the distribution of funds has been slow. Health officials express frustration over the lack of communication regarding funding status, which complicates their planning and operations. If delays continue, unspent funds may have to be returned to the Treasury, further jeopardizing public health initiatives.

Predictive Integrity Learning Framework (PILF) Summary

The Predictive Integrity Learning Framework (PILF) is a cognitive learning system that aims to improve how machine learning models adapt during training. Instead of using fixed settings for learning rates and model capacities, PILF uses real-time data evaluation to determine how much the model should learn from each data batch.

Key Points:

1. Dynamic Learning Strategies:

   • Traditional models rely on static hyperparameters, which can limit their effectiveness.
   • PILF replaces these with data-driven strategies that adjust learning rates and model capacities based on the "Surprise" level in data—indicating how much new information is present.

2. Core Implementation Stages:

   • Stage Zero: Introduced gated backpropagation to selectively update model weights based on Surprise.
   • Stage One: Implemented a dynamic learning rate scheduler (PILR-S) that adjusts learning rates based on Surprise metrics.
   • Stage Two: Combined the dynamic learning rate with a mixture of experts (MoE) architecture using static expert selection.
   • Stage Three: Developed a fully adaptive system where both the learning rate and the number of active experts are adjusted dynamically based on data complexity.
   • Stage Four (Current): Focused on creating a self-organizing architecture that moves from passive to active learning through a new routing mechanism.

3. Future Directions:

   • Plans to enhance the system further by integrating Gaussian distributions for improved routing and adding generative models to support knowledge retention.

4. Installation and Usage:

   • Users can set up the PILF framework by cloning its repository and installing necessary dependencies, including PyTorch.

5. Theoretical Contributions:

   • PILF transforms static hyperparameters into adaptive strategies, improves efficiency through on-demand resource allocation, and mitigates issues like catastrophic forgetting by linking learning processes with Surprise.

This framework aims to make machine learning models more efficient and responsive to the information they encounter during training.

Bogong moths migrate long distances—up to 1,000 km—from southeast Australia to cool caves in the Australian Alps during spring and return to their breeding grounds in autumn. Researchers discovered that these moths navigate using the stars as a compass to find their way. In experiments, moths were tethered in a flight simulator and showed they could maintain their migratory direction even in the absence of the moon and under changing star positions.

The study suggests that the moths have specialized brain cells that respond to the night sky, helping them orient themselves southward, which is crucial for their long journeys. Even when clouds blocked the stars, the moths continued to fly northward, indicating they also rely on the Earth’s magnetic field for navigation.

Overall, the findings reveal that Bogong moths can use both stellar cues and magnetic fields to navigate effectively over long distances, making them unique among invertebrates for their ability to determine specific geographical directions using the night sky.

Summary: PNG is Back!

A new PNG specification has been released after over two decades of stagnation, bringing exciting updates. The U.S. Library of Congress and other major institutions recommend PNG, highlighting its importance.

Key Updates:

1. HDR Support: The new PNG supports High Dynamic Range images, which enhances color representation using only 4 bytes.
2. APNG Recognition: Animated PNGs, previously proposed by Mozilla, are now officially recognized and widely supported.
3. Exif Data Support: PNG now supports Exif data for storing information like copyright and GPS location.
4. General Improvements: The spec includes fixes and clarifications.

Background: The last PNG update was over 20 years ago, and advancements in technology, particularly the need for HDR support, led to this revival. Major companies like Adobe, Apple, and Google contributed to the development.

Current Support: Many popular programs, including Chrome, Firefox, and Photoshop, already support the new PNG spec.

Future Plans: The PNG Working Group is already planning further updates, including better compression and improved compatibility between HDR and Standard Dynamic Range.

Thanks to the PNG Working Group for their hard work in making this happen!
