Mathematical Modeling Reveals Just How Bad the Dreidel Game Is

2024-12-18

Last year, the author used the PRISM probabilistic modeling language to model the traditional holiday game Dreidel, proving its lack of fun. This year, he refined the model to simulate the entire game until its conclusion. The new model corrects the previous flaw of only simulating the elimination of the first player and improves the calculation logic for betting and player elimination. Through model simulation, the author found that, on average, a four-player game takes 760 spins to end, and the longest can even exceed 6 hours. This fully proves that the Dreidel game is long, tedious, and frustrating.

USDA Strengthens Food Safety Measures After Deadly Listeria Outbreaks

2024-12-18

Following two deadly Listeria monocytogenes outbreaks linked to Boar's Head deli meats and Yu Shang ready-to-eat meat and poultry products, resulting in dozens of illnesses and multiple deaths, the USDA's Food Safety and Inspection Service (FSIS) has finally acted. Despite prior knowledge of deficiencies at the Boar's Head facility, FSIS failed to intervene until after the outbreak. The agency announced stronger measures, including expanded testing, improved inspector training, and enhanced facility oversight, to prevent future incidents. This highlights vulnerabilities in food safety regulation and the critical need for prompt and effective intervention.

Starlink Sells Out in Zimbabwe Amidst High Demand

2024-12-17

Starlink's high-speed satellite internet service quickly sold out in Zimbabwe within weeks of its launch, driven by the country's slow, unreliable, and expensive traditional internet infrastructure. High demand led to sell-outs in major cities like Harare, and even spread to other African countries. Despite higher initial costs, Starlink's unlimited data and superior speeds are proving attractive to many, forcing local providers to lower their prices. While currently facing capacity issues in urban areas, Starlink's potential in rural and underserved regions is significant, boosting related industries such as installation services and accessory sales.

A Glimpse into OS/2's Built-in Virtualization

2024-12-17

This blog post explores the surprisingly advanced built-in virtualization capabilities of OS/2 2.1 from 1993. The author demonstrates OS/2's ability to load and execute disk images, much like modern hypervisors, by creating a simple VGA mode program and running it in DOSBox, QEMU, and OS/2's own virtual environment. OS/2 can even run images that aren't true bootable DOS floppies, using VMDISK to create an image file and running it in fullscreen or windowed mode within OS/2. This functionality, remarkable for 1993, is essentially a built-in QEMU, prompting the author to consider the further potential of OS/2's virtualization features.

W54: The Pocket-Sized Nuke of the Cold War

2024-12-18

The W54, also known as the Mark 54 or B54, was the smallest nuclear weapon ever deployed by the United States. Its remarkably compact design, boasting a yield ranging from 10 to 1,000 tons of TNT, made it suitable for various applications, including the AIM-26 Falcon air-to-air missile, the Davy Crockett recoilless rifle, and the Special Atomic Demolition Munition (SADM) system. Developed in the late 1950s, the W54's creation presented significant engineering challenges, particularly concerning its environmental sensing device. A later variant, the W72, was integrated into the AGM-62 Walleye guided bomb and remained in service until 1979.

Ryzen 7 9800X3D Teardown Reveals Mostly Dummy Silicon

2024-12-18

A teardown of AMD's Ryzen 7 9800X3D processor reveals a surprising finding: the majority of its volume is comprised of dummy silicon for structural integrity. While the SRAM cache die is significantly smaller than the compute die, AMD has added a substantial layer of dummy silicon above and below to protect the thin, fragile components. This results in a total package thickness of roughly 800µm, with dummy silicon accounting for a staggering 93%. Despite the seemingly wasteful design, it ensures stability and thermal performance. AMD is expected to announce 12-core and 16-core Ryzen 9 X3D processors soon.

Making Unsafe Rust Safer: Verification Tools for Unsafe Code

2024-12-17

Rust's popularity stems from its ability to eliminate memory and concurrency errors at compile time, but its `unsafe` code blocks can bypass these checks. This article explores tools for verifying unsafe Rust code, including code called from C or C++ libraries. It introduces runtime error detection tools—sanitizers—and Miri, an interpreter that deterministically finds undefined behavior. Sanitizers detect out-of-bounds memory access, data races, and more, while Miri provides more precise error reporting with code snippets. However, Miri currently doesn't support code called via FFI from C/C++, necessitating the use of C/C++ compiler sanitizers in such cases. These tools enhance the safety and reliability of Rust code, even when dealing with `unsafe` code or interacting with C/C++ libraries.

RTO Mandates Lead to Tech Talent Exodus, Study Finds

2024-12-17

A study tracking over 3 million employees at 54 S&P 500 high-tech and financial firms reveals that return-to-office (RTO) mandates are causing companies to lose top talent and struggle to find replacements. The research found a 14 percent average increase in employee turnover after RTO policies were implemented, with senior and skilled employees more likely to leave. Women experienced nearly three times the attrition rate of men. Furthermore, RTO mandates prolonged hiring times and increased costs. Companies' attempts to enforce RTO policies through surveillance tactics, such as VPN tracking and badge swipe monitoring, fueled employee resentment and furthered the exodus. The study suggests that RTO mandates reflect a culture of distrust and ineffective management, leading to decreased employee engagement.

Attention as Electromagnetic Field Line Management: A New Model of Consciousness

2024-12-17

Qualia Research Institute proposes a novel model of attention, conceptualizing it as the management of dynamic patterns in the brain's electromagnetic field. By simulating electric field lines arising from weighted sums of harmonic oscillations, researchers demonstrate how attention controls charge density by modulating underlying resonant modes, explaining seemingly random fluctuations and drifts in attentional behavior. This model also offers a potential explanation for psychedelic experiences, suggesting that psychedelics disrupt the normal flow of attention by altering the configuration of harmonic modes. The research provides a new lens for understanding consciousness and developing novel neuro-interventions, such as inducing exotic states of consciousness by non-invasively perturbing the phase locking of attention.

OpenAuth is a universal, standards-based, open-source authentication provider. Deployable as a standalone service or embedded within existing applications, it's framework-agnostic and runs on Node.js, Bun, AWS Lambda, or Cloudflare Workers. Adhering to OAuth 2.0, OpenAuth offers a customizable, themeable UI. Unlike most open-source auth solutions which are libraries, OpenAuth is a centralized server designed for easy self-hosting on your infrastructure. It intentionally omits user management, instead providing callbacks for custom user lookup/creation. Data storage is minimal (refresh tokens, etc.) using a simple KV store (Cloudflare KV, DynamoDB). A pre-built UI is available, but you can easily customize or replace it entirely. Created by the SST team, OpenAuth simplifies authentication for your applications.
