Summary of "Towards Fearless SIMD, 7 Years Later"

In March 2025, Raph Levien revisits his earlier vision for improving SIMD (Single Instruction, Multiple Data) programming in Rust. Although there has been some progress, writing SIMD in Rust remains challenging. The need for SIMD is highlighted by new projects using CPU/GPU hybrid rendering techniques.

A key issue is that SIMD intrinsics in Rust are marked as unsafe due to the varying support across CPUs. This means developers must ensure the CPU can handle SIMD instructions, which complicates code safety.

Levien provides examples of computing a sigmoid function using SIMD, showcasing the complexity of writing safe and efficient SIMD code. He discusses multiversioning, which allows the same code to run optimally on different CPU architectures, but notes that Rust lacks robust solutions compared to libraries like Highway in C++.

The article also touches on the trends in SIMD, such as the growing use of smaller scalar types like FP16 for better performance, and mentions upcoming features in Intel's AVX10. Additionally, he discusses the ongoing development of the std::simd library, though he expresses concerns about its focus on portability over performance optimization.

Levien emphasizes the need for Rust to improve its SIMD support, making it safer and more ergonomic, and encourages community discussion on how to achieve this. He believes that enhancing SIMD capabilities in Rust is crucial for the language's performance and usability in future projects.

Summary: Accessible Open Textbooks in Math-Heavy Disciplines

The main issue is that LaTeX, a popular tool for creating high-quality documents in math-heavy fields, only outputs in PDF format, which is not accessible for many users. PDFs can’t be easily adjusted for different devices or formats, and they don't provide necessary semantic information for screen readers.

A better solution is to use HTML, which is more accessible and works well with assistive technologies. However, displaying mathematical formulas in HTML can be challenging. MathML is a format designed for this purpose but isn't fully supported by all web browsers. MathJax can help display these formulas correctly on web pages.

Alternatives to LaTeX include:

1. Pressbooks: A web-based tool that supports LaTeX but is not widely used in math-heavy fields.
2. PreTeXt: An XML-based platform that converts content into multiple formats, including HTML and LaTeX.
3. Markdown: A simple markup language that can be easily converted to various formats and is popular in disciplines like statistics.

Each alternative has pros and cons, especially concerning the complexity of existing LaTeX projects. A significant barrier is that authors need to learn new tools and languages, unlike LaTeX, which has a vast ecosystem of features.

Another option is to convert existing LaTeX documents to HTML using tools like LaTeXML, which is effective but requires additional work to make the output visually appealing. BookML can enhance this process by providing styling options and features for online learning systems.

A case study from the University of Calgary shows how an open textbook was successfully adapted for accessibility, which involved converting LaTeX to HTML and ensuring compatibility with screen readers.

Testing for accessibility can be difficult, and while many automated tools exist, thorough testing often requires expertise and resources. The author faced challenges in balancing accessibility features for different screen readers and user needs.

Overall, the document emphasizes the importance of making math-heavy educational resources accessible and the challenges involved in achieving this goal.

Apple's recent promotional video for the TV show Severance unintentionally revealed a significant flaw in its appeal to professional video editors. The video showcased the editing process using a Mac, but it became clear that the editing was actually done remotely via a screen-sharing tool called Jump Desktop. This means that the powerful editing capabilities were not coming from the Mac Mini on screen, but from another Mac located elsewhere.

This highlights a critical issue: Apple’s professional offerings are designed for single machines, which can be a disadvantage in the growing field of remote editing. Many editors are now using cloud-based tools, which could potentially outperform individual Macs. Apple's lack of traditional server options and limitations on virtual machine use make it less competitive in this area.

As remote editing becomes more common, especially post-COVID, Apple may need to rethink its approach to better serve high-end users. The video inadvertently shows that while the Macs featured are present, they are not central to the editing process, suggesting that Apple's offerings could be outpaced by competitors who focus on cloud services and virtual machines.

Utah has become the first state in the U.S. to ban fluoride in public drinking water, with the law signed by Governor Spencer Cox taking effect on May 7. This decision follows concerns from health officials, including Robert F. Kennedy Jr., who suggested that fluoride may have health risks, particularly for children. Critics, including dental health experts, argue that removing fluoride could harm oral health, as it has been used since 1945 to prevent cavities.

The new law prohibits communities from adding fluoride to their water supplies, and supporters of the ban argue it gives people the choice to consume fluoride or not. However, many public health organizations, including the American Dental Association and the Centers for Disease Control and Prevention, advocate for fluoride in water, citing its benefits in reducing tooth decay. They argue that the potential risks associated with fluoride are not supported by evidence from the low levels used in water systems.

While some other states like Florida and Ohio are considering similar bans, experts warn that Utah's decision could negatively impact public health, especially for children.

The article discusses the mysterious flow of cerebrospinal fluid (CSF) in the brain and its potential role in waste removal, particularly during sleep. Researchers have debated how the brain clears waste since it lacks a traditional drainage system like the rest of the body.

Recent studies suggest that the pumping action of blood vessels may help move CSF, which could assist in eliminating waste. A prominent theory called the "glymphatic hypothesis" proposes that this process is most effective during sleep, making sleep feel refreshing. However, this hypothesis is contested by some scientists who question the mechanisms proposed.

A new study from the University of Rochester used mice to explore how CSF flows during sleep and implicated a neurotransmitter, norepinephrine, in driving this fluid movement. While some researchers support the glymphatic hypothesis, others express skepticism and emphasize the need for further investigation to fully understand how waste is cleared from the brain.

Overall, the flow of CSF and its connection to sleep and brain health remains a complex and actively researched topic.

Summary of Ubuntu's User Namespace Bypasses

Qualys Security Advisory reported three methods to bypass Ubuntu's restrictions on unprivileged user namespaces, which were introduced to enhance security in Ubuntu 23.10 and enabled by default in Ubuntu 24.04. These restrictions aim to prevent unprivileged users from exploiting kernel vulnerabilities.

1. Bypass via aa-exec: An attacker can use the aa-exec tool to switch to certain AppArmor profiles (like chrome or flatpak) that allow full capabilities, enabling the creation of user namespaces.

2. Bypass via BusyBox: The BusyBox shell, which is installed by default, also allows the creation of user namespaces with full capabilities. An attacker can access it to bypass the restrictions.

3. Bypass via LD_PRELOAD: By using the LD_PRELOAD mechanism with the Nautilus program, another default application, an attacker can execute a shell that creates user namespaces with full capabilities.

These bypasses effectively grant unprivileged users administrative capabilities within user namespaces, which can lead to exploitation of kernel vulnerabilities. For more technical details, refer to Ubuntu's discussions on the topic.

The advisory was sent to the Ubuntu Security Team on January 15, 2025, and a coordinated release of information occurred on March 27, 2025.

The article discusses the limitations of universal health benchmarks in assessing child growth and nutrition, highlighting the need for more individualized standards that account for human diversity.

Key points include:

1. Universal Health Standards: Current health metrics, like growth charts, assume a one-size-fits-all model for defining malnutrition and growth abnormalities, ignoring the diversity in human biology and environmental adaptation.

2. Personal Experience: The author shares their experience with their daughter, who was classified as "wasted" despite being healthy and active, illustrating the disconnect between clinical assessments and individual health.

3. Global Health Data Issues: Studies indicate that global health metrics often rely on data from specific populations (mainly Western) and can misrepresent the health of diverse groups, leading to inappropriate health interventions.

4. The South Asian Enigma: Research shows that populations from South Asia often appear smaller in standard health metrics but may not be unhealthy, contradicting the assumptions made by universal standards.

5. Call for Change: The article advocates for developing health metrics that reflect local populations and conditions instead of imposing universal standards that may mislabel healthy individuals as malnourished.

6. Conclusion: The reliance on outdated and broad health benchmarks can lead to misdiagnoses and ineffective public health policies. A shift towards acknowledging individual and population differences in health assessments is essential for better health outcomes.

A German railway company recently advertised a job for a Windows 3.11 Administrator, needing someone experienced with this 30-year-old operating system and MS-DOS. The job involves managing systems with very old hardware—specifically, 166MHz processors and 8MB of RAM. These outdated systems are still crucial for operating display boards on trains, showing real-time technical data to drivers. While it may seem concerning that modern railways rely on such ancient software, many critical systems stay with older technology because they are deemed reliable. The job listing was quickly removed, but it indicates that these legacy systems may remain in use until at least 2030.

Summary:

The author describes how to create a self-contained executable Python script using the uv package. They have a script called jam_users.py that manages user data in a local API. Traditionally, running this script required setting up dependencies in a global Python environment or a virtual environment, which can be cumbersome.

To simplify this, the author uses uv, which allows embedding dependencies directly in the script header. By adding a special comment at the top of the script, they can run it using uv without manually managing dependencies or environments.

The author enhances the script's shebang line to allow it to be executed directly, making it easier to run on any Unix system with uv installed. This method eliminates the need for users to prepare their systems, streamlining the process of running Python scripts.

Overall, this approach makes it easier to share and run Python scripts without worrying about dependency management.

In 1976, Peter Kirstein helped connect Queen Elizabeth II to the internet by setting up her email account at the Royal Signals and Radar Establishment in England. This event marked her as one of the first world leaders to send an email. The Queen's username was "HME2," and her first message announced the availability of a programming language called Coral 66 on the ARPANET, the precursor to the internet.

Kirstein played a crucial role in bringing the ARPANET to the UK, establishing a connection at the University of London in 1973 and later expanding it to other locations. He facilitated this connection despite initial plans being hindered by political issues. His work contributed to the development of TCP/IP protocols, which led to the creation of the modern internet. In recognition of his contributions, Kirstein was inducted into the Internet Hall of Fame in 2012.

Summary of Episode 438: The Real Book

Since the mid-1970s, most jazz musicians have used a book called the Real Book, which has a homemade look and contains sheet music for hundreds of jazz standards. However, it was initially illegal because it was self-published without permission from music publishers.

The concept of fake books, which help musicians play songs they don’t know, started in the 1940s with George Goodwin's Tune-Dex. Jazz musicians needed an easier way to manage sheet music, leading to the creation of cheap, organized fake books. Over time, many illegal versions emerged because music publishers opposed them.

By the mid-1970s, students at Berklee College of Music, frustrated with outdated fake books, decided to create the Real Book, which included modern jazz songs and updated chord changes. They hand-notated the music and made it visually appealing, and it quickly became popular among musicians.

Eventually, bootleg versions of the Real Book spread worldwide. In the mid-2000s, Hal Leonard published a legal version, securing rights for the songs and allowing composers to receive royalties, though some authorship issues remain unresolved.

Despite its popularity, the Real Book faces criticism. Some argue it simplifies jazz too much and reduces a rich cultural tradition to a mere study guide. Critics believe true jazz understanding comes from immersion in the culture and learning directly from experienced musicians. While the Real Book can be a useful starting point, it’s important for musicians to explore various interpretations of songs and develop their unique styles.

The European Union (EU) is mandating that Apple replace its proprietary peer-to-peer Wi-Fi protocol, Apple Wireless Direct Link (AWDL), with the open standard Wi-Fi Aware, also known as Neighbor Awareness Networking (NAN). This change is part of the EU's Digital Markets Act (DMA), which aims to improve interoperability between devices. Apple must implement Wi-Fi Aware 4.0 in its upcoming iOS 19 update and support Wi-Fi Aware 5.0 shortly thereafter.

Historically, AWDL provided Apple devices with fast, high-performance peer-to-peer communication, enabling features like AirDrop and AirPlay. However, it was limited to Apple products and did not allow cross-platform connectivity. Wi-Fi Aware, on the other hand, is an open standard that enables devices from different manufacturers to discover and connect to each other directly via Wi-Fi, enhancing compatibility between iPhones and Android devices.

The key benefits of Wi-Fi Aware include efficient discovery, high data throughput, low latency, and enhanced security features. This shift will allow developers to create applications that work seamlessly across both Apple and Android platforms without the need for complex workarounds.

In summary, the EU's regulations are pushing Apple to adopt a standard that will facilitate better interoperability, allowing devices from different brands to connect easily and paving the way for innovative applications in local networking.

Researchers have discovered that Prototaxites, a large ancient organism once thought to be a type of fungus, may actually be a completely unknown branch of life. This organism existed between 420 million and 375 million years ago and could grow up to 26 feet tall. Initially classified as a fungus due to its structure and feeding habits, recent studies suggest it might belong to an entirely different group of eukaryotes.

Fossils of Prototaxites, including a species called Prototaxites taiti found in Scotland, show unique internal structures that differ from known fungi. Chemical analyses revealed that it lacked chitin, a key component of fungal cell walls, and instead contained materials similar to those in plants. This discovery raises questions about its classification and suggests that Prototaxites represents a novel form of multicellular life that is now extinct. Further research is needed to fully understand this mysterious organism.

The Ivanpah Solar Power Plant in California, operated by NRG Energy Inc., will close some of its units after more than 11 years of operation. This decision follows the termination of long-term power purchase agreements with Pacific Gas and Electric Co. (PG&E), as newer solar technologies have become more cost-effective. Ivanpah, which was once the largest concentrating solar power plant in the world, uses mirrors to concentrate sunlight and generate power but has faced performance issues and environmental criticisms, including bird fatalities.

The U.S. Department of Energy had supported the project with $1.6 billion in loan guarantees, and negotiations to end the contracts aimed to recover loans and save costs for California ratepayers. NRG is now seeking approvals to begin decommissioning the units next year and has suggested that the site could be repurposed for newer solar technologies after the shutdown.
