Researchers have discovered that bonobos use a form of syntax previously believed to be unique to humans. This means they can combine vocal sounds in complex ways to create new meanings, indicating that the basic elements of human language may also be found in our closest relatives.

The study, led by Mélissa Berthet and her team, involved observing 30 bonobos in the Kokolopori Bonobo Reserve in the Democratic Republic of the Congo. They recorded nearly 1,000 calls and noted the context of each call. By analyzing these calls, the researchers found that bonobos can combine sounds in ways that produce meanings not directly related to the individual sounds, demonstrating a type of "non-trivial compositionality."

For example, a combination of calls that typically means "pay attention to me" and "I am excited" could mean "pay attention to me because I am in distress." This suggests that bonobos have a sophisticated communication system that shares similarities with human language.

While this discovery highlights the complexity of bonobo communication, it does not mean they possess language as humans do. The findings suggest that the ability for such complexity in communication may have been inherited from a common ancestor shared with humans, dating back at least 7 million years.

The text explains how the shebang (#!) works in scripts on Linux systems, which specifies the interpreter to run the script. For example, a shell script might start with #! /usr/bin/sh and a Python script with #! /usr/bin/python3. This allows users to run scripts simply by invoking them directly (e.g., ./script.sh) if the script has execute permissions.

The shebang is essential because many Linux utilities are scripts, and it helps the kernel identify the correct interpreter to use when executing these scripts. The kernel handles this process directly, rather than relying on the shell.

When a script is executed, the kernel reads the first line to find the interpreter specified by the shebang. If the script lacks a shebang, it may still run, but the shell will have to infer its type, which can lead to errors. The text also discusses how permissions are checked when executing scripts, emphasizing the importance of having the correct execute permissions set.

Overall, the shebang is a crucial feature in Linux that allows for easy execution of scripts by specifying the interpreter directly within the script file.

Summary: Why Tap a Wheel of Cheese?

Each year, around 4 million wheels of Parmigiano Reggiano are produced, and a small team of 24 specialists, known as battitori, checks their quality. Using a metal hammer, these experts tap each wheel after it has aged for at least 12 months, listening for any defects in sound within seconds.

The author, Kristine Jannuzzi, spent time with two battitori, Alessandro Stocchi and his mentor Renato Giudici. Stocchi, who started training in 2014, learned the craft through hands-on experience with skilled mentors. The job demands precision and care to avoid damaging the cheese.

When assessing cheese, the battitori tap it in a quiet setting. A consistent sound indicates a perfect wheel, while irregular sounds suggest structural flaws like cracks or cavities. Parmigiano Reggiano is graded into three categories: top quality (no defects), good quality (minor defects), and lower quality (significant flaws, not labeled as Parmigiano Reggiano).

Stocchi notes that some defects are a natural part of artisanal cheese making, reflecting the variations in raw ingredients. Only about 10% of wheels have minor defects, and only 1.5% have significant flaws. The job requires passion and a commitment to continuous learning, as there’s always more to discover in the craft.

Apple's machine learning researchers have introduced a new technique called Activation Transport (AcT) to improve control over generative models, such as those used for text and image creation. These models are powerful but can be unpredictable and fail to meet user expectations. Traditional methods for fine-tuning these models, like reinforcement learning with human feedback (RLHF), are resource-intensive and may disrupt overall performance.

AcT allows for precise control over model outputs without needing to change the model's internal parameters or requiring extensive computational resources. It uses optimal transport theory to adjust activations in a way that maintains the model's expected behavior. This technique is beneficial for tasks that require specific outputs, such as ensuring sensitivity in content generation or altering artistic styles in images.

AcT has shown effective results in reducing toxic language and improving truthfulness in generated text while also allowing for nuanced changes in image generation. It provides an interpretable way to control how much influence is applied during the generation process, making it a versatile solution for various applications in generative modeling. The code for implementing AcT is available for researchers and developers to use.

The text discusses FastCGI, a protocol for handling web requests, and compares it to modern web server practices. FastCGI allows long-lived processes to serve multiple requests, unlike the older cgi-bin method that runs a new script for each request. The author experiments with FastCGI in Rust, using a library called fastcgi, and sets up a simple server.

However, after testing, the author questions the benefit of FastCGI compared to using an embedded web server, like Tide in Rust, which is easier to set up and doesn't require additional web server configuration. The conclusion is that while FastCGI can still be useful for certain scripted languages, most developers should opt for simpler HTTP web servers.

The text discusses the idea of having specific business hours for websites, similar to physical stores. It mentions that while many websites operate 24/7, some, like B&H Photo, choose to close on certain days for various reasons. The author highlights that the estimated revenue loss during downtime, often calculated for e-commerce sites, can be overstated since not all customers will abandon their carts immediately.

B&H has taught customers to return later if the site is closed, which suggests that not being available all the time can be manageable. The text also cites other examples of websites that have scheduled downtime or limited availability, emphasizing that these sites don’t provide urgent services and have unique offerings that keep customers coming back.

The author proposes that if a website had scheduled downtime, it could save on cloud costs. For instance, by taking one day off per week, a site could potentially save money instead of losing all revenue during downtime. Ultimately, the text concludes that while there are benefits to having limited hours, the need for constant availability remains strong for many businesses.

Summary: Why Lead is Still Bad for Your Brain

Lead is a heavy metal that has been used for centuries in many products, but it is toxic and dangerous, especially for the brain. Although lead levels in the environment have decreased since the 1970s, there is no safe level of lead exposure.

Lead can enter the body through ingestion or inhalation, and children are particularly vulnerable because they absorb lead more easily. Once in the body, lead can accumulate in soft tissues and bones, where it can remain for years. Chronic exposure can lead to serious health issues, including memory problems, cognitive deficits, and behavioral issues.

The toxic effects of lead are not limited to high levels; even small amounts can be harmful. Lead disrupts cellular processes, affects calcium signaling in neurons, and generates harmful reactive oxygen species, damaging brain cells.

To protect against lead exposure, it's important to address potential sources in homes and communities. Safe removal of lead-based paint and pipes, as well as community advocacy for lead removal programs, are key steps. Early interventions can help mitigate the effects of lead exposure, especially in children.

In summary, while society has made progress in reducing lead exposure, it remains a significant health risk, particularly for vulnerable populations.

Summary: Unit Testing with Mocks in Go

Unit testing is crucial for ensuring code quality, especially when working with cloud services like AWS, where creating real resources (like S3 buckets) can be restricted. Mocks help simulate these services for testing purposes.

   • Real testing environments may not always be available (e.g., AWS permissions).
   • Mocks allow for testing error cases that are hard to replicate in real systems.

2. Creating a Testable Function:

   • A function to create an S3 bucket is defined, which checks if the bucket exists after creation.
   • This function requires an interface instead of a concrete S3 client to facilitate mocking.

3. Defining an Interface:

   • An interface is created to outline the necessary methods for bucket creation.
   • The original function is refactored to accept this interface, enabling the use of mock implementations.

4. Implementing Mocks:

   • A mockS3Client struct is created to implement the defined interface.
   • This mock can simulate successful bucket creation and failure scenarios.

5. Testing:

   • Initial tests are written to check both successful and failed bucket creation.
   • Tests are refactored into table-driven tests for better organization and scalability.

6. Future Improvements:

   • Additional checks (like validating bucket names) can be added to the tests.
   • Libraries like Mockery can automate mock generation and provide more features.

This tutorial provides a framework for effectively using mocks in Go to ensure code can be tested without relying on external systems.

The Jupiter Ace was a home computer launched in the UK in 1982, notable for using Forth programming language instead of the more common BASIC. Despite its unique feature, it failed commercially and production ended after a year. BASIC was important at that time because it was interactive, compact, and familiar to many users, functioning as a simple user interface for early home computers.

Forth, while more efficient and faster for serious software development, was less known and harder to learn, which limited its appeal. The main reason for Jupiter Ace's failure was not the choice of programming language but its outdated hardware—only 3KB of RAM and basic graphics, compared to competitors like the ZX Spectrum and Oric-1 that offered color and more memory.

In summary, while the inclusion of Forth made the Jupiter Ace stand out, it ultimately couldn't compete due to its inferior hardware. For those interested in learning Forth, using a Jupiter Ace emulator is a recommended approach.

Summary:

The SuperNote A6 X2 Nomad tablet, created by Ratta Software, was found to have a serious security vulnerability, allowing attackers to remotely install a rootkit without user interaction. This issue was designated CVE-2025-32409.

The discovery began with a routine scan of the device, revealing an open port (60002). Researchers examined the device's firmware and found that it allowed unauthenticated file transfers, which they exploited to upload files to the tablet.

They identified a flaw in the naming convention for files uploaded to a specific directory. When an attacker tried to upload a file named "update.zip," the system would rename it to "update(1).zip" if a file with that name already existed. This posed a challenge because the device required the update file to be named exactly "update.zip" to trigger an installation.

To circumvent this, the researchers devised a strategy using a "race condition." They sent a small dummy file named "update.zip" first, which completed its upload quickly. Immediately afterward, they sent the actual malicious update file. This clever timing allowed the malicious file to be recognized as "update.zip," enabling the installation of the rootkit during normal device operation.

The timeline of disclosing the vulnerability involved multiple communications with Ratta Software, culminating in a promise to address the issue in a future update. PRIZM Labs, the security firm behind the discovery, specializes in security for defense and aerospace sectors and offers various security services.

In a recent speech at the ASU+GSV Summit, U.S. Education Secretary Linda McMahon mistakenly referred to artificial intelligence (AI) as "A1," similar to a brand of steak sauce. This occurred multiple times during her talk about innovations in education, where she discussed how AI could enhance learning for young students. McMahon, who is working on dismantling the Department of Education under President Trump, faced confusion over her mix-up, especially since she mentioned AI correctly beforehand. McMahon has a net worth of about $3.2 billion and aims to promote creativity in education, arguing that the U.S. doesn't always need a Department of Education. While she and Trump seek to reduce the department's role, congressional approval is required for its formal closure.

The photographs were originally in black and white and later hand-colored, a common practice of that era. The author reflects on how the world depicted in these photos has changed significantly since then, making it unrecognizable to anyone from that time. The post invites readers to explore these historical images and consider Japan's transformation over the years.

A recent study suggests that Saturn's moon Titan might have the potential to support life, but only in very limited quantities. Titan is unique due to its thick atmosphere and abundant organic materials, including lakes and rivers of liquid methane. Researchers, led by Antonin Affholder and Peter Higgins, used bioenergetic modeling to explore how life could exist in Titan's subsurface ocean, which could be up to 300 miles deep.

Their findings indicate that while simple, microscopic life could exist on Titan, the overall biomass would be minimal—comparable to a small dog. They emphasize that not all organic compounds on Titan may be suitable food for life, and the exchange of materials between the surface and the ocean is limited.

The study particularly focused on glycine, a simple amino acid, and found that only a small portion of Titan's organic materials might be accessible to potential microbes. The researchers concluded that finding life on Titan would be challenging, akin to searching for a needle in a haystack, as the rich organic inventory may not be as beneficial for habitability as previously thought. Future missions, like NASA's Dragonfly, planned for launch in 2028, aim to explore Titan further.

Summary of New Window Commands for Emacs

Introduction: In September 2024, the author found a package called transpose-frame.el for managing window layouts in Emacs. Inspired by an article by Tobias on better practices, the author requested to move this package into Emacs core. However, the package had many issues that would require a complete rewrite rather than just code changes.

Development Process: The author volunteered to rewrite the package, which turned out to be a complex task involving collaboration with Emacs maintainers. After about four months of work, the new functionality was integrated into Emacs version 31, now available in a file called window-x.el.

New Commands: The following commands can be used for managing window layouts in Emacs 31:

1. Transpose Layout:
   M-x transpose-window-layout - Reflects the layout diagonally.

2. Rotate Layout:
   M-x rotate-window-layout-clockwise - Rotates the layout clockwise.
   M-x rotate-window-layout-anticlockwise - Rotates the layout counterclockwise.

3. Flip Layout:
   M-x flip-window-layout-horizontally - Flips the layout horizontally.
   M-x flip-window-layout-vertically - Flips the layout vertically.

4. Cycle Windows:
   M-x rotate-windows - Cycles through the windows.
   M-x rotate-windows-back - Reverses the cycle.

These commands can enhance window management and can be explored in various layouts. If you don't have Emacs 31, this is just a preview of the new features.

MIT engineers have developed a method to engineer bacteria that can detect pollutants and nutrients, acting as sensors for farmers to monitor crops. These bacteria produce unique color signals that can be detected from up to 90 meters away using hyperspectral cameras.

The researchers created two types of bacteria that emit different wavelengths of light when they sense specific molecules. This allows for long-distance monitoring, which is more practical than traditional methods that require microscopes. The technology can be adapted to various sensors, making it versatile for different applications, such as detecting chemicals in soil or monitoring crop health.

The study demonstrates a new way to gather data from bacterial cells, which could lead to advancements in agricultural monitoring and other fields. Before these sensors can be deployed, they need to be approved by regulatory agencies. The research was funded by the U.S. Department of Defense and other organizations.

The Trump administration recently decided not to impose further restrictions on Nvidia's H20 chip, which is a key AI chip sold to China. This change happened after Nvidia CEO Jensen Huang attended a high-profile dinner at Mar-a-Lago, where he discussed future U.S. investments in AI data centers.

Previously, there was significant pressure on the administration to place stricter export controls on this chip due to concerns that it could enhance China's military and AI capabilities. Despite the planned restrictions being in place for months, the White House's reversal is seen as a victory for China, as the H20 chip is still better than many of its domestic alternatives.

In the first quarter of this year, Chinese companies purchased $16 billion worth of H20 chips in anticipation of these controls. The U.S. has faced delays in implementing export controls due to staffing shortages at the Bureau of Industry and Security, which handles such regulations. Some lawmakers expressed disappointment over the decision to ease restrictions, emphasizing the need for tighter controls to prevent adversaries from gaining technological advantages.

Summary: Parser Combinators vs. Regexes in Haskell

In a discussion about solving programming challenges in Haskell, the author highlights the preference for parser combinators over regular expressions (regexes) for parsing tasks. Here's a simplified breakdown:

1. Community Preference: Haskell developers typically avoid regexes due to issues like lack of community cohesion around regex libraries. Instead, they prefer parser combinators, which offer better performance and flexibility.

2. Regex Example: A regex solution for a specific problem (from Advent of Code) successfully extracts and calculates products from a string input. However, it has performance issues and relies on assumptions that can lead to runtime errors if the input format changes.

3. Parser Solution: A parser using the attoparsec library is introduced. Although it requires more upfront work, it offers better guarantees about input handling. The parser explicitly checks for valid input formats and avoids runtime exceptions.

4. Stateful Parsing: As the problem evolves to include instructions that enable or disable contributions to the sum, a stateful parser can be implemented using state transformers. This allows the parser to maintain and adapt to changes in state without the limitations of regex.

5. Performance: The parser solution runs significantly faster (0.07 seconds) compared to the regex version (19 seconds) on the same input size, demonstrating the efficiency of parser combinators.

6. Flexibility and Maintenance: Parser combinators provide greater flexibility for future changes, making them easier to maintain compared to regexes, especially for complex input structures.

In conclusion, while regexes might seem simple for straightforward tasks, parser combinators are preferred in Haskell for their performance advantages, safety, and adaptability to changing requirements.
