Apple Issues Warnings for Apps Using External Payment Systems in the EU

2025-05-15

Apple has begun issuing warnings for apps in the EU that use external payment systems instead of in-app purchases (IAP). The warning appears prominently at the top of the App Store listing, even after an app has been installed and updated. This has raised concerns among developers, despite the EU's Digital Markets Act (DMA) prohibiting scare screens at the point of purchase. Apple defines three warning levels in macOS, and the external payments warning uses the highest 'critical' level. However, developers question how many users will notice these warnings, as apps can auto-update, adding external payment functionality without requiring users to revisit the App Store.

Swift Move Semantics: A Comparison with C++

2025-01-09

This article delves into the similarities and differences between move semantics in Swift and C++. Swift automatically performs move optimizations, which is beneficial for performance but can surprise C++ programmers accustomed to the RAII idiom. Swift's "non-copyable types" are similar to C++'s "move-only types," but Swift's moves are destructive, avoiding potential issues with C++'s "non-destructive moves." The article compares Swift's `consume` with C++'s `std::move`, and explains Swift's shortened variable lifetimes, parameter passing conventions (`consuming`, `borrowing`, `inout`), and the Law of Exclusivity. Finally, it discusses using non-copyable types for RAII, generics, and conditionally copyable types in Swift, and why Swift lacks perfect forwarding.

Universe's Demise Prediction Debunked: A Scientific Mishap Based on Crude Approximation

A recent paper claimed that any massive object emits Hawking radiation, leading to the universe ending sooner than expected. This conclusion sparked widespread attention but was quickly challenged. Critics pointed out that the paper used a crude approximation, whose results are proven false even in simpler models. In fact, the physics community rigorously proved 50 years ago that the gravitational field of a static object does not create particle-antiparticle pairs. This incident highlights the importance of information verification in science communication and the need for critical thinking when interpreting scientific findings.

Mystery Solved: Apple II MouseCard's VBL-Synced Interrupts

This post delves into the synchronization mechanism between the Apple II MouseCard's IRQ interrupts and vertical blanking (VBL). The author initially observed flickering in MAME emulation but smooth rendering on real hardware. Through community interaction and analysis of the MouseCard firmware, the mystery was solved: the MouseCard doesn't directly receive the VBL signal but uses software on a 68705 microprocessor to precisely calculate and trigger interrupts, achieving VBL synchronization. This involves manipulating 6821 PIA registers and configuring the 68705's internal timer, ultimately achieving highly accurate VBL synchronization, consistent with Apple's official documentation.

Birds' Brains: Convergent Evolution of Cognitive Power

New research using single-cell RNA sequencing reveals surprising similarities in the brain structures of birds and mammals, despite their distinct evolutionary paths. Scientists have long puzzled over how birds, lacking a neocortex, possess complex cognitive abilities. The study found that the avian dorsal ventricular ridge (DVR) functionally mirrors the mammalian neocortex, but its development, cell types, and generation timing differ significantly, suggesting independent evolution rather than inheritance from a common ancestor. This challenges long-held beliefs about brain evolution and suggests our understanding of 'optimal intelligence' may be too narrow.
