The content discusses the challenges faced by programmers who are not familiar with macOS when writing code that will run on this operating system. It emphasizes the importance of understanding macOS's unique features, particularly regarding energy consumption, which is a major priority for Apple. The M1 Pro processor, for example, has a significant range in power consumption, from 10 mW to 40 W, necessitating careful consideration of how to optimize performance versus energy use. The post advocates for assigning "quality of service

PRoot is a user-space tool that allows users to implement features typically requiring root privileges, such as changing the root filesystem (chroot) and using bind mounts, without needing special setup. It enables users to utilize any directory as the new root filesystem (guest rootfs), access files from the actual filesystem (host rootfs), and run programs built for different CPU architectures using QEMU user-mode. PRoot confines program execution to the guest rootfs but allows access to host files via its built-in

The 1970 World Expo in Osaka, Japan, themed "Progress and Harmony for Mankind," attracted 64 million visitors from 77 countries. A notable exhibit was the Sanyo Ultrasonic Bath, where users would enter a chamber to experience a 15-minute cycle of warm water jets, ultrasonic cleaning, rinsing, and drying, enhanced with infrared and ultraviolet light for sanitation. Though this prototype never went into production, it inspired Japan's Science Group to develop a new version for the upcoming

The article, presented at the 2016 International Cycling History Conference, discusses an M.I.T. course from 1974 led by Professor Shawn Buckley, where students, including Marc Rosenbaum and Harriet Fell, built their own bicycle frames. Marc, a senior mechanical engineering student at the time, aimed to design an ultra-light bicycle that provided acceleration benefits without compromising stiffness. He emphasized stiffness over strength, noting that frames typically don't break during racing. The paper details Marc's design and the bicycles he

The special report titled “Reinventing Invention: Stories From Innovation’s Edge” highlights the visionary work of Bill Harding in 1970, who aimed to create a fully automated wafer-fabrication line capable of producing integrated circuits in under a day. This ambitious goal was realized through Project SWIFT, a groundbreaking initiative led by Harding while he was a manager at IBM's Manufacturing Research group. The project required a revolutionary redesign of manufacturing processes, leading to innovations that are now standard in the semiconductor industry

The author has been researching LLM-based evaluations, specifically "LLM-as-a-Judge" metrics, for language models, with promising results in areas such as hallucination detection and content moderation. However, developing these metrics has proven challenging due to the need to understand data structure and the probabilistic nature of LLM outputs. While some hosted model providers offer structured output modes, they have limitations, especially for open-source models. The author proposes structured generation as a solution, which constrains generative model

This study investigates the link between sleep regularity, measured through accelerometers, and the risk of major adverse cardiovascular events (MACE) in adults aged 40-79 from the UK Biobank. It categorizes sleep regularity into three groups: irregular, moderately irregular, and regular. The study followed 72,269 participants over eight years, finding that both irregular and moderately irregular sleepers faced a higher risk of MACE compared to regular sleepers. Specifically, irregular sleep was associated with a hazard ratio

The content discusses tools developed for controlling the webcam LED on the ThinkPad X230, enabling software-based manipulation without physical access. This technology serves as a demonstration of potential vulnerabilities, showing how malware could disable the LED while recording video through the webcam. By reflashing the webcam firmware over USB—thanks to its internal USB connection—the LED can be controlled arbitrarily. This technique could extend to many other laptops due to common design patterns. The document references a talk given at POC 2024, which

C-Reduce is a tool developed by Regehr and colleagues designed to minimize bug reproducer files for C compilers. Instead of sending a large C file (e.g., 10,000 lines) that triggers a compiler bug, users can leverage C-Reduce to automatically reduce the size of the file, making it more manageable for developers. Although many believe C-Reduce works only for C, it is actually widely applicable. The author shares an example where they encountered a bug with RustPython

C++20 introduced two significant features: `requires` and `requires { requires }`, which simplify overload resolution and enable reflection-based optimizations in templates when combined with `if constexpr` from C++17. The `requires` clause allows function overloads to be enabled or disabled based on compile-time conditions. For instance, it can restrict overloads to specific types, such as integers or floating-point numbers, improving overload resolution efficiency. The concept of "subsumption" is integral, as it

The article discusses common misconceptions about Haskell, specifically focusing on the treatment of effectful computations as first-class values. It emphasizes that in Haskell, side effects, such as generating random numbers, are not executed immediately when functions like `randomRIO` are called. Instead, calls to `randomRIO` can be stored in data structures without triggering any randomness until explicitly executed. The author explains that the values returned by such functions are not actual integers, but rather encapsulated instructions for generating those integers later

The advisory discusses a long-standing arbitrary code execution vulnerability in Emacs identified as CVE-2024-53920. This vulnerability allows arbitrary code execution when viewing or editing Emacs Lisp code due to unsafe macro-expansion that runs unrestricted code, affecting most common configurations. Although the issue has been known for several years, it has not yet been resolved, though Emacs maintainers are working on future countermeasures. Users are advised to take precautions to protect themselves while using existing versions. L

A new scroll dataset, PHerc. 172, has been released in collaboration with the Bodleian Library, University of Oxford, Diamond Light Source, and EduceLab. This ancient scroll dates back to around 79 AD, when it was buried during the Mount Vesuvius eruption. It was later gifted to the future George IV of England by Ferdinand IV of Naples, allegedly in exchange for kangaroos. Currently housed at the Bodleian Library, PHerc. 172 was

The content discusses the challenges faced by an incident management company that relies on its own alerting system, particularly the paradox of needing the system to notify about its own failures. To address this issue, they have developed a "dead man's switch" for their on-call system, ensuring they can still receive alerts even if their product fails. This system has never been needed due to their own failures, but they emphasize the importance of having a contingency plan for worst-case scenarios. The post also provides a brief example
