A recent study published in Nature Neuroscience raises doubts about the reliability of functional magnetic resonance imaging (fMRI) as a measure of brain activity. Researchers from the Technical University of Munich and Friedrich-Alexander-University Erlangen-Nuremberg found that in about 40% of cases, increased fMRI signals actually corresponded to reduced brain activity. This contradicts the belief that more brain activity always leads to increased blood flow for oxygen.

During experiments with healthy participants, the researchers used a new MRI technique to measure oxygen consumption alongside fMRI signals. They discovered that some brain regions increased their oxygen usage without needing more blood flow, which means they were using existing oxygen more efficiently.

These findings suggest that many fMRI studies on brain disorders, such as depression or Alzheimer's, may need to be re-evaluated. The changes in blood flow measured may not accurately reflect neuronal activity but rather vascular changes. The researchers recommend combining traditional fMRI with quantitative measurements of oxygen consumption to create a more accurate understanding of brain energy usage. This could lead to improved insights into various brain conditions.

Overall, the study challenges long-held assumptions about fMRI and suggests a new direction for brain research.

Summary of Vilgot Huhn's Blog Post on P-Values and Lindley’s Paradox

Vilgot Huhn discusses the limitations of p-values in hypothesis testing, particularly the common practice of p-value circling, which involves scrutinizing p-values near the conventional threshold of 0.05. This practice stems from a long-standing arbitrary choice of 0.05 as a cutoff for significance, leading to questions about its validity.

Key Points:

1. P-Value Basics: P-values measure the probability of observing data as extreme as the sample data, assuming the null hypothesis is true. The traditional threshold of 0.05 is widely used, but there’s no solid justification for this specific value.

2. P-Value Circling: This refers to the practice of highlighting p-values that are close to 0.05 to express skepticism about their reliability. Huhn argues that this skepticism may be somewhat justified due to potential researcher biases and questionable practices like p-hacking.

3. Limitations of P-Values: Huhn explains that p-values do not account for the context of the study, including sample size and the actual presence of effects. He emphasizes that a single p-value does not provide strong evidence of statistical malpractice.

4. Lindley’s Paradox: This paradox highlights that p-values between 0.04 and 0.05 could indicate surprising results if the test has high power. However, Huhn argues that using p-values in this way can lead to confusion and misinterpretation, as p-values are not designed to directly measure evidence for or against hypotheses.

5. Conclusion: Huhn concludes that while it’s important to recognize the limitations of p-values, relying on them alone for assessing evidence is insufficient. He suggests that other statistical measures, such as Bayes factors, may provide better insights into evidence strength.

Overall, the post encourages a careful and contextual approach to interpreting p-values, without overemphasizing their role in determining the validity of research findings.

A BBC investigation revealed that children with cancer have been exploited in scam fundraising campaigns, resulting in millions of dollars being raised without benefiting the families. Many parents were approached to film emotional videos of their sick children, often under false pretenses. For example, a mother named Aljin was misled into filming her son Khalil, who had cancer, and was told the video would raise funds for his treatment. Although the campaign claimed to have raised $27,000, Aljin received only a small filming fee and no money for her son’s care. Khalil later died.

The investigation identified a scam network led by an Israeli man named Erez Hadari, who orchestrated these fraudulent campaigns through an organization called Chance Letikva. Many families were unaware that their stories were being used for fundraising, and numerous parents reported receiving little to no money from the campaigns, despite significant amounts being raised.

The scam targets vulnerable families, often using emotional and distressing tactics to elicit donations. The campaigns were well-produced and appeared legitimate, raising suspicions about their authenticity. Experts noted that fundraising costs should be limited, but scammers often misused funds for advertising instead. The investigation continues, and the BBC calls for scrutiny of such fundraising efforts to protect vulnerable families.

Times New Roman is named after the Times of London, which commissioned typographer Stanley Morison in 1929 to create a new font. Despite some early criticism about its design, it quickly gained popularity, especially in newspapers where narrow fonts were preferred for fitting more text. Over the years, Times New Roman has remained widely available with new typesetting technologies.

While it’s a functional font, its reputation suffers because it’s often seen as the default choice, suggesting a lack of creativity. This is particularly true in the legal field, where many lawyers use it out of habit rather than necessity, mistakenly believing it’s required by courts.

In summary, Times New Roman is a practical but uninspired font, and there are many better alternatives available.

In 2024, over four million children in the U.S. were uninsured, marking a significant increase in the uninsured rate, which reached 6.1%, the highest in a decade. This lack of insurance can lead to delayed medical care, particularly for serious conditions like pediatric cancer, which can worsen outcomes. Many uninsured children qualify for government programs like Medicaid but aren’t enrolled due to lack of awareness or fear of deportation among immigrant families.

The rise in uninsured children is partly due to bureaucratic issues, such as states re-checking Medicaid eligibility after the COVID pandemic, leading to wrongful disenrollment. This situation is critical, as uninsured children are more likely to die from cancer due to late diagnoses and inadequate treatment. Studies show that uninsured children face higher mortality rates compared to those with private insurance.

Experts emphasize the need for a healthcare system that ensures all children have continuous insurance coverage. Solutions include fixing administrative errors and improving access to Medicaid enrollment support. Overall, addressing these gaps is vital to protect children's health and ensure timely treatment for serious illnesses.

Summary: Making Rails Global IDs Safer

On December 10, 2025, the author discusses the risks of using Rails Global IDs (GIDs) in applications, especially when integrating with large language models (LLMs). GIDs are unique identifiers for models in Rails, functioning like URLs that point to specific records.

Key Points:

1. What are GIDs? GIDs are string identifiers for models in Rails applications, formatted like gid://app_name/ModelName/ID. They are primarily used for serialization in ActiveJob.

2. LLMs and GIDs: LLMs can generate GIDs from the text they process. However, this can lead to security issues because:

   • GIDs can be manipulated and are not guaranteed to be generated by the application.
   • GIDs bypass authorization checks, potentially exposing sensitive data.
   • Rails' find method can mistakenly interpret GIDs, leading to incorrect data retrieval.

3. Security Risks: If an LLM generates a GID that resembles a valid ID but points to the wrong record, users could access data that does not belong to them.

4. Preventative Measures:

   • Create a specialized locator that checks the integrity of GIDs and enforces authorization.
   • Use signed GIDs to prevent LLMs from generating unsafe identifiers.
   • Treat any input from LLMs as untrusted, implementing strict checks when handling GIDs.

5. Best Practices: Instead of using GIDs directly, it's safer to use signed IDs that require specific permissions for access.

In conclusion, while GIDs offer useful functionality, they pose significant security risks when used with LLMs. Implementing strict controls and using safer alternatives is essential to mitigate these risks.

Summary:

Matt Stoller discusses a recent revelation about how Pepsi and Walmart allegedly colluded to raise food prices. A report from the Atlanta Fed shows that grocery store monopolies lead to higher food inflation. Specifically, the complaint from the FTC, which was initially hidden, claims that Pepsi kept its prices high for all stores except Walmart, giving Walmart a competitive edge. This "price gap" strategy harms smaller grocery stores and leads to higher prices for consumers.

Pepsi has been accused of engaging in price discrimination, violating the Robinson-Patman Act, by offering better deals and promotional allowances to Walmart while charging other retailers more. This partnership benefits both companies but disadvantages consumers and smaller competitors. The FTC's complaint was unsealed after a nonprofit intervened, revealing the extent of this market manipulation.

The situation has sparked political reactions, with calls for stricter regulations on price discrimination. There is a growing public awareness that pricing practices are unfair and that monopolistic behavior needs to be addressed. The article highlights a historical context of price discrimination and suggests a revival of anti-monopoly sentiments similar to past movements against unfair business practices.

To solve this, they used a Raspberry Pi 4 to monitor the HDMI bus and send necessary commands when a console was turned on. They built a Python script that detects when a console becomes active and sends a command to ensure the audio system switches on correctly, avoiding manual adjustments.

The process involved understanding CEC addresses and commands, tracking device communication, and creating a system that reacts to console activity. The author notes that this setup could be adapted for other HDMI-CEC issues, emphasizing the importance of having a reliable mechanism to manage audio and video sources automatically.

Overall, the solution significantly improved their home theater experience, allowing for smoother transitions between devices without manual input.

A user on Hacker News created a notification tool called UDP-7777 because they find regular notifications overwhelming and ineffective. This tool is designed to provide simple alerts by beeping until acknowledged, mimicking the functionality of 1990s pagers.

Key features include:

• No Cloud: It operates without accounts or central servers, using UDP Port 7777 for direct communication between devices.
• CAPCODES: It assigns a retro 10-digit code (CAPCODE) to your IP address, resembling a phone number.
• Minimal Design: The interface is straightforward, featuring just a box, buttons, and a prominent alert light.

Technically, UDP-7777 is a small program written in Go that uses "burst fire" UDP to ensure message delivery without the delays of TCP. The latest version (2.2.7) includes features like frequency tuning for specific networks, optional security keys to filter messages, and persistent alerts until acknowledged.

This tool is aimed at people wanting to minimize distractions, such as DevOps teams or individuals needing focused work time. The creator welcomes feedback on the IP-to-phone-number mapping feature. You can find more information and download the program at udp7777.com.

A MAGA-themed messaging app called Freedom Chat had a serious security breach that exposed users' phone numbers and PINs. The app, which claimed to be highly secure with features like end-to-end encryption and no metadata collection, was found to be misleading. A researcher discovered that it collected metadata and used a third-party service to store messages in a way that allowed anyone to read them easily.

Upon testing the app, it was revealed that every user’s PIN was visible to all other members in a channel, compromising their security. Moreover, the app used a contact discovery feature similar to WhatsApp, which could allow users to enumerate phone numbers, potentially matching them with their associated PINs.

The vulnerability was reported to Freedom Chat, which initially promised fixes. However, the issues were not adequately addressed, leading to the exposure of all users' phone numbers and PINs, rendering the PIN feature ineffective. The timeline of events showed that the vulnerability was discovered in late November 2025, disclosed to the company in early December, and by December 11, it was publicly revealed.

Microsoft has deactivated the IntelliCode extension for Visual Studio Code (VS Code) with the latest update (version 1.107). IntelliCode, which had over 60 million downloads, provided AI-assisted suggestions, but it is now deprecated, and its features will no longer work.

Instead, Microsoft is promoting its Copilot extension, which offers a limited free version that allows for 2,000 suggestions. After reaching this limit, users must purchase a paid license. Unlike IntelliCode, which was free and unlimited, Copilot's suggestions are limited per input.

The basic IntelliSense feature, which provides language support, remains free but does not include AI capabilities. The deactivation affects several IntelliCode-related extensions.

Additionally, the new update introduces experimental support for TypeScript 7 and enhancements for managing agents in VS Code, allowing developers more control over their development environment.

Summary: Avoid UUID Version 4 Primary Keys in PostgreSQL

Key Points:

1. Performance Issues with UUID v4:

   • UUID Version 4 keys are random, which leads to inefficiencies in database indexing, resulting in higher latency for inserts and lookups.
   • They consume more space (16 bytes) compared to integers (4 or 8 bytes), impacting overall database performance, especially with large datasets.

2. Misconceptions about UUIDs:

   • Many believe UUIDs are secure, but they are not meant to be used as secure identifiers.
   • There are better alternatives for generating unique identifiers, like using sequential integers or time-ordered UUIDs (e.g., UUID version 7).

3. Reasons to Avoid UUIDs:

   • Random UUIDs lead to more page splits in indexes, causing increased input/output (I/O) overhead and fragmentation.
   • They result in worse cache hit ratios, making it harder to efficiently access data.

4. Recommendations:

   • For new databases, use sequential integers or big integers as primary keys instead of UUIDs.
   • If UUIDs must be used, consider opting for time-ordered UUIDs (e.g., UUID version 7) to mitigate some performance issues.

5. Mitigation Strategies:

   • Regularly rebuild indexes and manage database memory settings to improve performance when using UUIDs.
   • Consider clustering tables on high-cardinality indexed columns to enhance query performance.

This summary emphasizes the drawbacks of using UUID v4 as primary keys in PostgreSQL and suggests alternatives for better database efficiency.

The rise of artificial intelligence (AI) is prompting discussions about whether machines should be taxed like human workers, especially as companies like Amazon and Meta announce layoffs due to automation. With fewer workers, there are concerns about decreased tax revenues, as most tax income comes from labor. Some, like Nobel laureate Edmund Phelps and Bill Gates, have proposed taxing robots to maintain social benefits.

Experts suggest that rather than a specific tax on AI, governments might consider raising capital gains taxes to address potential revenue losses. AI is expected to boost global GDP, but it could also lead to job transformation rather than outright elimination. There is a mix of optimism and caution regarding job creation and the need for a balanced tax system that encourages job growth.

Concerns about income inequality and the environmental impact of AI technologies are also highlighted. Overall, the debate continues about how to adapt tax systems and address the challenges posed by AI while ensuring shared prosperity.

John Varley, a notable science fiction writer, passed away on December 10, 2025. He gained fame in the mid-1970s with his imaginative "Eight Worlds" stories, set in a future where aliens have eliminated humans on Earth but humanity survives elsewhere in the Solar System. These stories featured unique concepts like gender-changing, memory banking, and the stark contrast of wealthy cities becoming shantytowns at night.

Varley produced many influential works, including "In the Hall of the Martian Kings" and "Air Raid." His novel "Titan" was expected to start a classic trilogy. For a time, he was compared to legendary writer Robert Heinlein.

However, Varley later moved to Hollywood, where he struggled with scriptwriting, leading to a decline in his prominence. Although he returned to writing and maintained his talent, his ideas were no longer as groundbreaking, as newer authors like William Gibson and Neal Stephenson emerged.

Many readers will remember Varley as a significant figure in science fiction, particularly during his peak. He inspired a generation of writers and fans, but his later works did not reach the same level of impact. His legacy remains as a brilliant storyteller who once set the standard in the genre.

Summary: Custom Yellow Handshake Emojis with Zero-Width Joiners

In December 2025, the article discusses how to create custom yellow handshake emojis using a technique involving zero-width joiners (ZWJs).

1. Background: In 2022, Apple introduced multi-skin tone handshake emojis, allowing users to create variations like 🫱🏻‍🫲🏿. However, these emojis are made up of multiple Unicode codepoints, unlike the traditional 🤝 emoji, which is a single codepoint.

2. How It Works: Each emoji is composed of Unicode characters. The traditional handshake emoji is represented by one codepoint (U+1F91D), while the multi-skin tone handshake uses several (e.g., U+1FAF1 for the right hand, U+1F3FB for skin tone, and ZWJs to combine them).

3. Creating New Handshakes: By understanding the construction of these emojis, users can create new variations, such as a yellow and black handshake. This involves modifying only one hand’s skin tone and utilizing ZWJs to combine them into a single character.

4. Limitations: Although these custom emojis can be created, they may not appear as large messages on Apple devices because they are treated as text rather than emojis.

Overall, the piece explains the technical aspects of creating and customizing emoji handshakes using codepoints and ZWJs while highlighting the limitations of rendering on certain platforms.

A study using data from 1980 to 2024 shows that 25% of US-trained STEM PhD graduates leave the US within 15 years of finishing their degree. The rates of leaving are lower in life sciences and higher in AI and quantum science, but they have remained stable over the years. Interestingly, even after these graduates leave, the US still benefits from their work. Although the US share of global patent citations from these graduates drops from 70% to 50% after they move, it is still five times more than what their new countries receive and equal to the total from all other countries. This indicates that the US gains value from training foreign scientists, whether they stay in the country or not.

SoundCloud has confirmed that it experienced a security breach that led to disruptions in VPN access and outages on its platform. During this breach, hackers stole a database containing users' email addresses and profile information, affecting about 20% of SoundCloud's users, which could mean around 28 million accounts are impacted.

SoundCloud stated that no sensitive data, like financial information or passwords, was accessed. The company activated its incident response procedures after detecting unauthorized activity and is now working with cybersecurity experts to enhance its security measures.

Although SoundCloud believes it has blocked all unauthorized access, the response to the breach inadvertently caused problems with VPN connectivity. The company hasn't provided a timeline for when VPN access will be restored. Additionally, the ShinyHunters extortion gang is reportedly behind the breach and is attempting to extort SoundCloud.

This situation is still developing, and more information may be released in the future.

Summary of Common Rust Lifetime Misconceptions

This article discusses common misconceptions about lifetimes in Rust, particularly for beginners. Here are the key points:

1. Types and Lifetimes:

   • T includes all types, not just owned types. It also encompasses borrowed types (&T and &mut T).
   • T is a superset of &T and &mut T, which are separate and disjoint sets.

2. 'static Lifetime:

   • T: 'static means that `T can live at least as long as the program, but it does not mean it must be valid for the entire program.
   • Types can be dynamically created at runtime and still have a 'static lifetime.

3. Reference Types:

   • &'a T (a reference) and T: 'a (any type valid for lifetime 'a) are not the same; the former is stricter in that it only allows references.

4. Generics and Lifetimes:

   • All Rust code typically involves generics and implicit lifetime annotations, even if you think your code is simple.

5. Compiler Behavior:

   • Just because code compiles does not mean the lifetime annotations are correct. Compiler messages can suggest fixes but might not lead to the best solution for your needs.

6. Lifetimes at Runtime:

   • Lifetimes are statically verified at compile-time and cannot change during runtime.

7. Mutability and References:

   • Downgrading mutable references to shared references can lead to issues, as the mutable borrow's lifetime may extend even after it’s dropped.

8. Closures:

   • Closures do not follow the same lifetime rules as functions, leading to confusion.

The article emphasizes the importance of understanding these concepts to avoid common pitfalls in Rust programming. It encourages users to give descriptive names to lifetime annotations and be mindful of their placement.

The article discusses the HTML <time> element, which is intended to provide a semantic way to represent dates and times on web pages. While it is used in about 8% of web pages, the author notes that it doesn't function as expected. Most browsers and assistive technologies do not utilize the <time> element for anything more than basic rendering, meaning it doesn't enhance user experience or accessibility as intended.

The author has researched its practical uses and discovered that it is primarily recognized by search engines for displaying date snippets, but there's little guidance from Google promoting its use. Instead, Google suggests using Schema.org's fields for dates. The article expresses disappointment that the <time> element remains underused and unfulfilled in its potential to improve web interactions, like adding events to calendars or localizing dates based on user preferences.

Overall, the <time> element is seen as a neat concept that, unfortunately, lacks practical application in today's web environment.

Summary:

Modals are often overused in design and development, leading to a frustrating user experience. They can be disruptive, confusing, and hard to escape, especially on small screens. Instead of using modals, consider alternatives like:

• Non-modal dialogs: Use for non-critical interactions that don’t block users.
• Inline content: Present information directly on the page.
• Expanding elements: Utilize accordions, tooltips, or sliding sidebars.
• New pages: Lead users to a separate page for interactions.
• Undo options: Allow users to undo actions without confirmation modals.

If you must use a modal, ensure it’s easy to close, focused on a single task, concise, and accessible. Avoid overly complex modals, such as multi-step or fullscreen ones, and steer clear of marketing modals. Always consider whether a modal is truly necessary.

The article discusses the C++ auto keyword, which allows the compiler to automatically deduce the type of a variable. It presents a series of coding examples to illustrate how type deduction works in different scenarios, categorized by difficulty levels: basic, intermediate, and advanced.

Key Points:

1. Basic Deductions:

   • auto v = 5; deduces v as int.
   • auto v = 0.1; deduces v as double.
   • Deductions can fail if types do not match, e.g., auto v = 5, w = 0.1; fails to compile.

2. Intermediate Deductions:

   • Deduces types based on references and qualifiers.
   • auto v = &x; keeps qualifiers like const and volatile.
   • auto& v = y; deduces v as a reference when using auto&.

3. Advanced Deductions:

   • Introduces more complex concepts like forwarding references and decltype.
   • Deduces types based on whether the expression is an lvalue or rvalue.
   • For example, decltype(auto) v = (x); deduces v as an lvalue reference.

4. Lambda and Structured Binding:

   • Deductions can become tricky with lambda captures and structured bindings.
   • For instance, capturing a reference in a lambda using decltype(auto) behaves differently depending on how the variable is captured.

Conclusion:

The article encourages readers to test these deductions and suggests checking their results using online tools. It invites readers to share their experiences or examples related to type deduction in C++.

Summary of Dinacon 2025: Passive Acoustic Listening

On August 3, 2025, Dinacon 2025 in Bali explored "passive acoustic monitoring," a method used to understand ecosystems through their sounds. This technique gained popularity after Roger Payne introduced whale songs to the public in 1970, which sparked interest in ocean conservation.

At the conference, workshops were held to teach participants how to create affordable hydrophones (underwater microphones) using simple electronic components. These hydrophones were tested in a koi pond to capture underwater sounds. The process involved making a waterproof case, assembling a pre-amp circuit, and using materials like silicone and Plasti Dip for durability.

Additionally, a stereophonic hydrophone was developed, allowing for spatial audio recording underwater. This involved placing two hydrophones at different depths to mimic how sound travels in water.

A project called "Seastream" aimed to broadcast live underwater sounds using a hydrophone connected to a Raspberry Pi. Despite initial success, connectivity issues halted the project.

Finally, two underwater microphones recorded sounds over four days in a coral reef. To help analyze these long recordings, a user-friendly tool called the Dinacon Hydrophone Explorer was created, allowing users to listen, annotate, and share observations from the recordings.

Overall, Dinacon 2025 highlighted the importance of listening to underwater ecosystems and encouraged innovative approaches to bioacoustic research.

Japan is set to update its romanization rules for the first time in 70 years. The Agency for Cultural Affairs has recommended replacing the current Kunrei system with the more popular Hepburn system. This change aims to reflect how Japanese is commonly spelled in both Japan and internationally.

The Kunrei system, established in 1954, uses spellings like "ti" and "hu," which will be changed to "chi" and "fu" under the Hepburn system. The new rules will also adapt spellings for other sounds, such as "shi" for し and "ji" for じ. The government plans to implement these changes gradually in educational materials, like textbooks.

Personal names and organizations will still be allowed to choose their preferred spellings. This review of romanization rules started in 2022, and the changes are expected to be approved within the current fiscal year.
