Benchmark: Bitwise vs. Modulo for Even Number Check

This post benchmarks two methods for checking if a number is even in Pascal and C: modulo operation and bitwise operation. The bitwise approach (using the bitwise AND operator) proves significantly faster. A Pascal test iterating from 0 to MaxInt showed bitwise operations were nearly 15 times quicker than modulo. In C, while compiler optimization might translate modulo 2 to bitwise AND, the bitwise method still slightly outperformed modulo. This highlights the efficiency advantage of bitwise operations for even number checks in performance-critical scenarios.

AppleCare+ Denies Claim for MacBook Pro Destroyed in Car Crash

A Redditor's MacBook Pro was totaled in a car accident. Despite having AppleCare+ for accidental damage, Apple denied the claim, citing the extent of the damage. While AppleCare+ covers accidental damage, vague clauses about "similar external causes" and "reckless conduct" allowed Apple to deny coverage. This raises questions about the scope of AppleCare+ protection and whether Apple is misinterpreting its own terms.

Halliday AR Glasses: A Unique Design with Significant Drawbacks

Halliday's AR glasses, showcased at CES, boast a novel optical design that deviates from conventional waveguide-based approaches. Employing a monocular projector to directly project images onto the eye via a mirror optical system, they offer advantages in brightness and efficiency, and compatibility with standard prescription lenses. However, users must look upward to view the image, leading to discomfort and social awkwardness. Stray light also results in a halo effect, diminishing contrast. Despite successful marketing, the design may hinder resolution and image quality improvements, and the lack of a camera limits its AI potential. While innovative, its drawbacks significantly outweigh the benefits.

Diablo Speedrun Champion Exposed as Cheater

Maciej "Groobo" Maselewski reigned supreme in Diablo speedrunning for years, his 3-minute, 12-second Sorceror run seemingly unbeatable. However, a team of speedrunners, attempting to replicate his seemingly lucky dungeon runs using external software, uncovered inconsistencies. An automated search through billions of legitimate Diablo dungeons proved Groobo's run impossible within the game's legitimate parameters. This revelation sparked controversy within the speedrunning community, exposing years of unearned praise and accolades based on fraudulent gameplay.

Chinese Scientists Achieve Breakthrough in High-Temperature Superconductivity

Scientists at Southern University of Science and Technology (Sustech) in China have observed high-temperature superconductivity in a thin film of nickel oxide crystals, achieving resistance-free electricity conduction at a relatively high temperature of 45 Kelvin (-228°C) without high pressure. Published in Nature, this research offers new hope for understanding the mechanism of high-temperature superconductivity and designing room-temperature superconductors. The discovery promises to make technologies like magnetic resonance imaging significantly cheaper and more efficient. While the critical temperature of nickel-based superconductors still needs improvement compared to copper-based ones, the team is actively exploring ways to optimize the material's growth and composition to further raise its critical temperature.

Viking Age Ice Grips: A Thousand Years of Traction

Archaeological finds reveal that Vikings used crampons to navigate icy winters over 1000 years ago. Various types of crampons, dating back to the Viking Age and the Middle Ages, have been unearthed from graves, showcasing their widespread use. Museum educator Espen Kutschera even tested a Viking-era pair, proving their effectiveness. Research suggests that despite the relatively high cost of iron in the Viking Age, crampons were likely accessible to many, highlighting the Vikings' ingenuity and adaptability to harsh winter conditions.

Rust Library Upgrade Challenges: A Clever Way to Avoid Version Conflicts

Upgrading libraries in the Rust ecosystem often causes cascading effects and significant trouble. This article introduces a technique called the "semver trick", which cleverly solves the problem of upgrading less frequently used APIs without changing commonly used ones by having a library depend on its future version. This method is particularly useful for avoiding the need for large-scale coordinated upgrades across the entire dependency chain due to breaking changes in a single library, greatly simplifying the upgrade process.

Sea Turtles' Secret Navigation: It's All in the Dance

Scientists have discovered that sea turtles use Earth's magnetic field for navigation, expressing memories of food locations through a unique "dancing" behavior. Researchers trained turtles to associate specific magnetic fields with food, and the turtles responded by excitedly "dancing" when they sensed the familiar field. Published in Nature, this study reveals that turtles possess two distinct magnetoreception mechanisms: a magnetic compass and a magnetic map, suggesting these mechanisms may have evolved separately. This provides crucial insights into understanding animal magnetoreception.

CES 2025 TVs: More AI Gimmicks Than Real Improvements

At CES 2025, TV manufacturers showcased AI-powered smart TVs, but Ars Technica's author expresses disappointment. Many touted AI features, such as LG's AI remote lacking a direct input switching button and Samsung's AI food recognition, prioritize corporate interests over user needs. Google TV's Gemini-enhanced Assistant also raises questions about practicality and potential subscription fees. The author argues that the industry's focus on software and data collection overshadows hardware improvements and user experience, forcing consumers to pay for largely useless features. Ultimately, many consumers simply desire TVs with superior picture and sound quality, a goal increasingly difficult to achieve without navigating through excessive gimmicks.

Rust: Investigating a Mysterious OOM

Qovery's engine-gateway, a Rust service, experienced unexpected out-of-memory (OOM) crashes. Monitoring showed stable memory usage before abrupt restarts. The culprit? The anyhow library, when backtraces are enabled, captures a backtrace for every error. Symbol resolution, only triggered when printing errors in debug mode (`{:?}`), caused massive memory consumption. Setting environment variables `RUST_BACKTRACE=1` and `RUST_LIB_BACKTRACE=0` to enable backtraces only on panic solved the issue. This highlights how monitoring can be deceptive and the importance of thorough library documentation review.

Rust Reflection: The Tug-of-War Between Safety and Access Rules

2025-01-03

Rust lacks reflection, a feature many developers desire. This article delves into the safety challenges of implementing reflection in Rust. Due to Rust's memory safety guarantees, a reflection API must adhere to strict access rules, preventing arbitrary access to private fields to avoid memory safety vulnerabilities. The author explores how these limitations impact reflection API design, such as handling reflection failures and expressing complex reflection bounds. The trade-offs between safe and unsafe reflection APIs are also discussed, along with balancing functionality and security. Ultimately, creating a safe reflection mechanism in Rust is a complex and challenging problem requiring careful consideration of various factors.

White House Seeks Oracle's Help to Save TikTok from US Ban

To prevent a nationwide ban, the White House is negotiating with Oracle and other investors to transfer control of TikTok's algorithm, data collection, and software updates to American companies. While ByteDance, TikTok's Chinese owner, would retain a minority stake, US investors would hold a majority. This aims to comply with US law mandating TikTok's separation from its Chinese parent company. However, the deal faces hurdles, including TikTok's high valuation and securing congressional approval. Recent signals from Chinese regulators suggest they won't block a majority US ownership, but uncertainties remain about the long-term commitment of the Trump administration and the cooperation of Apple and Google.
