Screenshotbot Ditches GitHub Dependency, Efficiently Uses git-upload-pack

2025-05-09

To enhance security and support more Git platforms, Screenshotbot initially chose not to read GitHub repositories. While this limited functionality, it improved user confidence and security review approval rates. The article details how Screenshotbot uses commit-graph construction and the git-upload-pack protocol to efficiently retrieve necessary information, supporting shallow clones and addressing the time-consuming issue of cloning large monorepos. The new method leverages existing SSH access in customers' CI jobs to directly access commit information via the git-upload-pack protocol, avoiding dependence on GitHub APIs. This improves efficiency, stability, and supports more platforms, including self-hosted Git repositories. Despite the complexities of the git-upload-pack protocol, the author notes several important details, such as the Packfile format and limitations of different Git servers. This article provides valuable experience and references for developers.

AI Code: From Vibrators to Pacemakers – How Far Can Our Trust in Code Go?

2025-07-10

The author uses the code of a vibrator and a pacemaker as examples to discuss the issue of code security and trust in the age of AI. The simple vibrator program and the complex pacemaker program are surprisingly similar in structure, but the latter concerns life safety and requires strict review and certification. The author questions whether, even if AI can write better code than humans in the future, we can fully trust AI-generated code, especially for programs related to life safety, such as a car's braking system. The author argues that radical transparency, including open code, specifications, and processes, is key to building trust, but the correctness of the code alone is not enough; comprehensive system understanding and security measures are also needed.

Google Maps Renames the Gulf of Mexico to 'Gulf of America'

Google Maps has updated its maps in the US to reflect the Trump administration's renaming of the Gulf of Mexico to the 'Gulf of America', showing the new name on both web and mobile platforms. Google states this follows the US Geographic Names Information System (GNIS). Mexican users still see 'Gulf of Mexico', while the rest of the world sees the original name with '(Gulf of America)' appended. Location is determined by mobile OS, SIM card, and network data. Desktop users see the changes based on search settings or device location. Apple Maps has yet to change, though redirects 'Gulf of America' searches to the Gulf of Mexico. Other map providers like MapQuest haven't updated either. Interestingly, Waze shows both names when searching 'Gulf of Mexico', but yields no results for 'Gulf of America'.

Lead-208 Nucleus: Not So Spherical After All

An international collaboration has overturned the long-held belief that the lead-208 (²⁰⁸Pb) atomic nucleus is perfectly spherical. Using high-precision experiments, researchers found it's slightly elongated, resembling a rugby ball. This challenges fundamental assumptions about nuclear structure and has significant implications for understanding the formation of heavy elements in the universe. The discovery involved bombarding lead atoms with high-speed particles and analyzing the resulting gamma-ray fingerprints. Theoretical physicists are now re-evaluating models of atomic nuclei, suggesting a more complex structure than previously thought.

Multithreading Super Mario Bros. on an NES Emulator: A Surprisingly Simple Feat

The author implemented multithreading in Super Mario Bros. on an NES emulator (FCEUX) using a Lua plugin, without modifying the emulator's core code. By leveraging the emulator's save state functionality, different game states were treated as separate threads. Synchronization primitives like mutexes and condition variables were implemented using specific in-game areas, allowing users to interact with threading concepts directly. For example, multiple Mario instances can play concurrently, but only one can enter a pipe at a time. This project demonstrates not only creativity but also provides a clear and engaging explanation of multithreading, highlighting the importance of understanding fundamental computer science concepts.

Trump's Trade War: Wall Street's Epic Miscalculation

The Trump administration's surprise announcement of new tariffs on nearly every country caught Wall Street completely off guard. The market had optimistically assumed a more moderate approach from Trump, a severe misjudgment. Trump's protectionist policies are unprecedented, imposing crushing tariffs not only on strategic rivals like China, but also on Vietnam, Bangladesh, and allies like the EU and Japan. This isn't reciprocal; it's unilateral and overwhelming. The result was a market panic. The article highlights Trump's extreme aversion to trade deficits and his bizarre methodology for calculating tariff rates as key factors. He views any trade deficit as America being 'ripped off,' ignoring the complexities and employing a nonsensical formula to support his view. Ultimately, investors' misreading of Trump led to the market crash, a direct consequence of Trump's consistent stance and policies.
